| 1 | =head1 NAME |
| 2 | |
| 3 | perldiag - various Perl diagnostics |
| 4 | |
| 5 | =head1 DESCRIPTION |
| 6 | |
| 7 | These messages are classified as follows (listed in increasing order of |
| 8 | desperation): |
| 9 | |
| 10 | (W) A warning (optional). |
| 11 | (D) A deprecation (optional). |
| 12 | (S) A severe warning (mandatory). |
| 13 | (F) A fatal error (trappable). |
| 14 | (P) An internal error you should never see (trappable). |
| 15 | (X) A very fatal error (non-trappable). |
| 16 | (A) An alien error message (not generated by Perl). |
| 17 | |
| 18 | Optional warnings are enabled by using the B<-w> switch. Warnings may |
| 19 | be captured by setting C<$SIG{__WARN__}> to a reference to a routine that will be |
| 20 | called on each warning instead of printing it. See L<perlvar>. |
| 21 | Trappable errors may be trapped using the eval operator. See |
| 22 | L<perlfunc/eval>. |
| 23 | |
| 24 | Some of these messages are generic. Spots that vary are denoted with a %s, |
| 25 | just as in a printf format. Note that some messages start with a %s! |
| 26 | The symbols C<"%-?@> sort before the letters, while C<[> and C<\> sort after. |
| 27 | |
| 28 | =over 4 |
| 29 | |
| 30 | =item "my" variable %s can't be in a package |
| 31 | |
| 32 | (F) Lexically scoped variables aren't in a package, so it doesn't make sense |
| 33 | to try to declare one with a package qualifier on the front. Use local() |
| 34 | if you want to localize a package variable. |
| 35 | |
| 36 | =item "my" variable %s masks earlier declaration in same scope |
| 37 | |
| 38 | (S) A lexical variable has been redeclared in the same scope, effectively |
| 39 | eliminating all access to the previous instance. This is almost always |
| 40 | a typographical error. Note that the earlier variable will still exist |
| 41 | until the end of the scope or until all closure referents to it are |
| 42 | destroyed. |
| 43 | |
| 44 | =item "no" not allowed in expression |
| 45 | |
| 46 | (F) The "no" keyword is recognized and executed at compile time, and returns |
| 47 | no useful value. See L<perlmod>. |
| 48 | |
| 49 | =item "use" not allowed in expression |
| 50 | |
| 51 | (F) The "use" keyword is recognized and executed at compile time, and returns |
| 52 | no useful value. See L<perlmod>. |
| 53 | |
| 54 | =item % may only be used in unpack |
| 55 | |
| 56 | (F) You can't pack a string by supplying a checksum, because the |
| 57 | checksumming process loses information, and you can't go the other |
| 58 | way. See L<perlfunc/unpack>. |
| 59 | |
| 60 | =item %s (...) interpreted as function |
| 61 | |
| 62 | (W) You've run afoul of the rule that says that any list operator followed |
| 63 | by parentheses turns into a function, with all the list operators arguments |
| 64 | found inside the parentheses. See L<perlop/Terms and List Operators (Leftward)>. |
| 65 | |
| 66 | =item %s argument is not a HASH element |
| 67 | |
| 68 | (F) The argument to exists() must be a hash element, such as |
| 69 | |
| 70 | $foo{$bar} |
| 71 | $ref->[12]->{"susie"} |
| 72 | |
| 73 | =item %s argument is not a HASH element or slice |
| 74 | |
| 75 | (F) The argument to delete() must be either a hash element, such as |
| 76 | |
| 77 | $foo{$bar} |
| 78 | $ref->[12]->{"susie"} |
| 79 | |
| 80 | or a hash slice, such as |
| 81 | |
| 82 | @foo{$bar, $baz, $xyzzy} |
| 83 | @{$ref->[12]}{"susie", "queue"} |
| 84 | |
| 85 | =item %s did not return a true value |
| 86 | |
| 87 | (F) A required (or used) file must return a true value to indicate that |
| 88 | it compiled correctly and ran its initialization code correctly. It's |
| 89 | traditional to end such a file with a "1;", though any true value would |
| 90 | do. See L<perlfunc/require>. |
| 91 | |
| 92 | =item %s found where operator expected |
| 93 | |
| 94 | (S) The Perl lexer knows whether to expect a term or an operator. If it |
| 95 | sees what it knows to be a term when it was expecting to see an operator, |
| 96 | it gives you this warning. Usually it indicates that an operator or |
| 97 | delimiter was omitted, such as a semicolon. |
| 98 | |
| 99 | =item %s had compilation errors |
| 100 | |
| 101 | (F) The final summary message when a C<perl -c> fails. |
| 102 | |
| 103 | =item %s has too many errors |
| 104 | |
| 105 | (F) The parser has given up trying to parse the program after 10 errors. |
| 106 | Further error messages would likely be uninformative. |
| 107 | |
| 108 | =item %s matches null string many times |
| 109 | |
| 110 | (W) The pattern you've specified would be an infinite loop if the |
| 111 | regular expression engine didn't specifically check for that. See L<perlre>. |
| 112 | |
| 113 | =item %s never introduced |
| 114 | |
| 115 | (S) The symbol in question was declared but somehow went out of scope |
| 116 | before it could possibly have been used. |
| 117 | |
| 118 | =item %s syntax OK |
| 119 | |
| 120 | (F) The final summary message when a C<perl -c> succeeds. |
| 121 | |
| 122 | =item %s: Command not found |
| 123 | |
| 124 | (A) You've accidentally run your script through B<csh> instead |
| 125 | of Perl. Check the #! line, or manually feed your script into |
| 126 | Perl yourself. |
| 127 | |
| 128 | =item %s: Expression syntax |
| 129 | |
| 130 | (A) You've accidentally run your script through B<csh> instead |
| 131 | of Perl. Check the #! line, or manually feed your script into |
| 132 | Perl yourself. |
| 133 | |
| 134 | =item %s: Undefined variable |
| 135 | |
| 136 | (A) You've accidentally run your script through B<csh> instead |
| 137 | of Perl. Check the #! line, or manually feed your script into |
| 138 | Perl yourself. |
| 139 | |
| 140 | =item %s: not found |
| 141 | |
| 142 | (A) You've accidentally run your script through the Bourne shell |
| 143 | instead of Perl. Check the #! line, or manually feed your script |
| 144 | into Perl yourself. |
| 145 | |
| 146 | =item B<-P> not allowed for setuid/setgid script |
| 147 | |
| 148 | (F) The script would have to be opened by the C preprocessor by name, |
| 149 | which provides a race condition that breaks security. |
| 150 | |
| 151 | =item C<-T> and C<-B> not implemented on filehandles |
| 152 | |
| 153 | (F) Perl can't peek at the stdio buffer of filehandles when it doesn't |
| 154 | know about your kind of stdio. You'll have to use a filename instead. |
| 155 | |
| 156 | =item 500 Server error |
| 157 | |
| 158 | See Server error. |
| 159 | |
| 160 | =item ?+* follows nothing in regexp |
| 161 | |
| 162 | (F) You started a regular expression with a quantifier. Backslash it |
| 163 | if you meant it literally. See L<perlre>. |
| 164 | |
| 165 | =item @ outside of string |
| 166 | |
| 167 | (F) You had a pack template that specified an absolute position outside |
| 168 | the string being unpacked. See L<perlfunc/pack>. |
| 169 | |
| 170 | =item accept() on closed fd |
| 171 | |
| 172 | (W) You tried to do an accept on a closed socket. Did you forget to check |
| 173 | the return value of your socket() call? See L<perlfunc/accept>. |
| 174 | |
| 175 | =item Allocation too large: %lx |
| 176 | |
| 177 | (X) You can't allocate more than 64K on an MSDOS machine. |
| 178 | |
| 179 | =item Allocation too large |
| 180 | |
| 181 | (F) You can't allocate more than 2^31+"small amount" bytes. |
| 182 | |
| 183 | =item Applying %s to %s will act on scalar(%s) |
| 184 | |
| 185 | (W) The pattern match (//), substitution (s///), and translation (tr///) |
| 186 | operators work on scalar values. If you apply one of them to an array |
| 187 | or a hash, it will convert the array or hash to a scalar value -- the |
| 188 | length of an array, or the population info of a hash -- and then work on |
| 189 | that scalar value. This is probably not what you meant to do. See |
| 190 | L<perlfunc/grep> and L<perlfunc/map> for alternatives. |
| 191 | |
| 192 | =item Arg too short for msgsnd |
| 193 | |
| 194 | (F) msgsnd() requires a string at least as long as sizeof(long). |
| 195 | |
| 196 | =item Ambiguous use of %s resolved as %s |
| 197 | |
| 198 | (W)(S) You said something that may not be interpreted the way |
| 199 | you thought. Normally it's pretty easy to disambiguate it by supplying |
| 200 | a missing quote, operator, parenthesis pair or declaration. |
| 201 | |
| 202 | =item Args must match #! line |
| 203 | |
| 204 | (F) The setuid emulator requires that the arguments Perl was invoked |
| 205 | with match the arguments specified on the #! line. Since some systems |
| 206 | impose a one-argument limit on the #! line, try combining switches; |
| 207 | for example, turn C<-w -U> into C<-wU>. |
| 208 | |
| 209 | =item Argument "%s" isn't numeric%s |
| 210 | |
| 211 | (W) The indicated string was fed as an argument to an operator that |
| 212 | expected a numeric value instead. If you're fortunate the message |
| 213 | will identify which operator was so unfortunate. |
| 214 | |
| 215 | =item Array @%s missing the @ in argument %d of %s() |
| 216 | |
| 217 | (D) Really old Perl let you omit the @ on array names in some spots. This |
| 218 | is now heavily deprecated. |
| 219 | |
| 220 | =item assertion botched: %s |
| 221 | |
| 222 | (P) The malloc package that comes with Perl had an internal failure. |
| 223 | |
| 224 | =item Assertion failed: file "%s" |
| 225 | |
| 226 | (P) A general assertion failed. The file in question must be examined. |
| 227 | |
| 228 | =item Assignment to both a list and a scalar |
| 229 | |
| 230 | (F) If you assign to a conditional operator, the 2nd and 3rd arguments |
| 231 | must either both be scalars or both be lists. Otherwise Perl won't |
| 232 | know which context to supply to the right side. |
| 233 | |
| 234 | =item Attempt to free non-arena SV: 0x%lx |
| 235 | |
| 236 | (P) All SV objects are supposed to be allocated from arenas that will |
| 237 | be garbage collected on exit. An SV was discovered to be outside any |
| 238 | of those arenas. |
| 239 | |
| 240 | =item Attempt to free non-existent shared string |
| 241 | |
| 242 | (P) Perl maintains a reference counted internal table of strings to |
| 243 | optimize the storage and access of hash keys and other strings. This |
| 244 | indicates someone tried to decrement the reference count of a string |
| 245 | that can no longer be found in the table. |
| 246 | |
| 247 | =item Attempt to free temp prematurely |
| 248 | |
| 249 | (W) Mortalized values are supposed to be freed by the free_tmps() |
| 250 | routine. This indicates that something else is freeing the SV before |
| 251 | the free_tmps() routine gets a chance, which means that the free_tmps() |
| 252 | routine will be freeing an unreferenced scalar when it does try to free |
| 253 | it. |
| 254 | |
| 255 | =item Attempt to free unreferenced glob pointers |
| 256 | |
| 257 | (P) The reference counts got screwed up on symbol aliases. |
| 258 | |
| 259 | =item Attempt to free unreferenced scalar |
| 260 | |
| 261 | (W) Perl went to decrement the reference count of a scalar to see if it |
| 262 | would go to 0, and discovered that it had already gone to 0 earlier, |
| 263 | and should have been freed, and in fact, probably was freed. This |
| 264 | could indicate that SvREFCNT_dec() was called too many times, or that |
| 265 | SvREFCNT_inc() was called too few times, or that the SV was mortalized |
| 266 | when it shouldn't have been, or that memory has been corrupted. |
| 267 | |
| 268 | =item Attempt to use reference as lvalue in substr |
| 269 | |
| 270 | (W) You supplied a reference as the first argument to substr() used |
| 271 | as an lvalue, which is pretty strange. Perhaps you forgot to |
| 272 | dereference it first. See L<perlfunc/substr>. |
| 273 | |
| 274 | =item Bad arg length for %s, is %d, should be %d |
| 275 | |
| 276 | (F) You passed a buffer of the wrong size to one of msgctl(), semctl() or |
| 277 | shmctl(). In C parlance, the correct sizes are, respectively, |
| 278 | S<sizeof(struct msqid_ds *)>, S<sizeof(struct semid_ds *)>, and |
| 279 | S<sizeof(struct shmid_ds *)>. |
| 280 | |
| 281 | =item Bad filehandle: %s |
| 282 | |
| 283 | (F) A symbol was passed to something wanting a filehandle, but the symbol |
| 284 | has no filehandle associated with it. Perhaps you didn't do an open(), or |
| 285 | did it in another package. |
| 286 | |
| 287 | =item Bad free() ignored |
| 288 | |
| 289 | (S) An internal routine called free() on something that had never been |
| 290 | malloc()ed in the first place. Mandatory, but can be disabled by |
| 291 | setting environment variable C<PERL_BADFREE> to 1. |
| 292 | |
| 293 | This message can be quite often seen with DB_File on systems with |
| 294 | "hard" dynamic linking, like C<AIX> and C<OS/2>. It is a bug of |
| 295 | C<Berkeley DB> which is left unnoticed if C<DB> uses I<forgiving> |
| 296 | system malloc(). |
| 297 | |
| 298 | =item Bad hash |
| 299 | |
| 300 | (P) One of the internal hash routines was passed a null HV pointer. |
| 301 | |
| 302 | =item Bad name after %s:: |
| 303 | |
| 304 | (F) You started to name a symbol by using a package prefix, and then didn't |
| 305 | finish the symbol. In particular, you can't interpolate outside of quotes, |
| 306 | so |
| 307 | |
| 308 | $var = 'myvar'; |
| 309 | $sym = mypack::$var; |
| 310 | |
| 311 | is not the same as |
| 312 | |
| 313 | $var = 'myvar'; |
| 314 | $sym = "mypack::$var"; |
| 315 | |
| 316 | =item Bad symbol for array |
| 317 | |
| 318 | (P) An internal request asked to add an array entry to something that |
| 319 | wasn't a symbol table entry. |
| 320 | |
| 321 | =item Bad symbol for filehandle |
| 322 | |
| 323 | (P) An internal request asked to add a filehandle entry to something that |
| 324 | wasn't a symbol table entry. |
| 325 | |
| 326 | =item Bad symbol for hash |
| 327 | |
| 328 | (P) An internal request asked to add a hash entry to something that |
| 329 | wasn't a symbol table entry. |
| 330 | |
| 331 | =item Badly placed ()'s |
| 332 | |
| 333 | (A) You've accidentally run your script through B<csh> instead |
| 334 | of Perl. Check the #! line, or manually feed your script into |
| 335 | Perl yourself. |
| 336 | |
| 337 | =item BEGIN failed--compilation aborted |
| 338 | |
| 339 | (F) An untrapped exception was raised while executing a BEGIN subroutine. |
| 340 | Compilation stops immediately and the interpreter is exited. |
| 341 | |
| 342 | =item bind() on closed fd |
| 343 | |
| 344 | (W) You tried to do a bind on a closed socket. Did you forget to check |
| 345 | the return value of your socket() call? See L<perlfunc/bind>. |
| 346 | |
| 347 | =item Bizarre copy of %s in %s |
| 348 | |
| 349 | (P) Perl detected an attempt to copy an internal value that is not copiable. |
| 350 | |
| 351 | =item Callback called exit |
| 352 | |
| 353 | (F) A subroutine invoked from an external package via perl_call_sv() |
| 354 | exited by calling exit. |
| 355 | |
| 356 | =item Can't "goto" outside a block |
| 357 | |
| 358 | (F) A "goto" statement was executed to jump out of what might look |
| 359 | like a block, except that it isn't a proper block. This usually |
| 360 | occurs if you tried to jump out of a sort() block or subroutine, which |
| 361 | is a no-no. See L<perlfunc/goto>. |
| 362 | |
| 363 | =item Can't "last" outside a block |
| 364 | |
| 365 | (F) A "last" statement was executed to break out of the current block, |
| 366 | except that there's this itty bitty problem called there isn't a |
| 367 | current block. Note that an "if" or "else" block doesn't count as a |
| 368 | "loopish" block, as doesn't a block given to sort(). You can usually double |
| 369 | the curlies to get the same effect though, because the inner curlies |
| 370 | will be considered a block that loops once. See L<perlfunc/last>. |
| 371 | |
| 372 | =item Can't "next" outside a block |
| 373 | |
| 374 | (F) A "next" statement was executed to reiterate the current block, but |
| 375 | there isn't a current block. Note that an "if" or "else" block doesn't |
| 376 | count as a "loopish" block, as doesn't a block given to sort(). You can |
| 377 | usually double the curlies to get the same effect though, because the inner |
| 378 | curlies will be considered a block that loops once. See L<perlfunc/last>. |
| 379 | |
| 380 | =item Can't "redo" outside a block |
| 381 | |
| 382 | (F) A "redo" statement was executed to restart the current block, but |
| 383 | there isn't a current block. Note that an "if" or "else" block doesn't |
| 384 | count as a "loopish" block, as doesn't a block given to sort(). You can |
| 385 | usually double the curlies to get the same effect though, because the inner |
| 386 | curlies will be considered a block that loops once. See L<perlfunc/last>. |
| 387 | |
| 388 | =item Can't bless non-reference value |
| 389 | |
| 390 | (F) Only hard references may be blessed. This is how Perl "enforces" |
| 391 | encapsulation of objects. See L<perlobj>. |
| 392 | |
| 393 | =item Can't break at that line |
| 394 | |
| 395 | (S) A warning intended for while running within the debugger, indicating |
| 396 | the line number specified wasn't the location of a statement that could |
| 397 | be stopped at. |
| 398 | |
| 399 | =item Can't call method "%s" in empty package "%s" |
| 400 | |
| 401 | (F) You called a method correctly, and it correctly indicated a package |
| 402 | functioning as a class, but that package doesn't have ANYTHING defined |
| 403 | in it, let alone methods. See L<perlobj>. |
| 404 | |
| 405 | =item Can't call method "%s" on unblessed reference |
| 406 | |
| 407 | (F) A method call must know what package it's supposed to run in. It |
| 408 | ordinarily finds this out from the object reference you supply, but |
| 409 | you didn't supply an object reference in this case. A reference isn't |
| 410 | an object reference until it has been blessed. See L<perlobj>. |
| 411 | |
| 412 | =item Can't call method "%s" without a package or object reference |
| 413 | |
| 414 | (F) You used the syntax of a method call, but the slot filled by the |
| 415 | object reference or package name contains an expression that returns |
| 416 | neither an object reference nor a package name. (Perhaps it's null?) |
| 417 | Something like this will reproduce the error: |
| 418 | |
| 419 | $BADREF = undef; |
| 420 | process $BADREF 1,2,3; |
| 421 | $BADREF->process(1,2,3); |
| 422 | |
| 423 | =item Can't chdir to %s |
| 424 | |
| 425 | (F) You called C<perl -x/foo/bar>, but C</foo/bar> is not a directory |
| 426 | that you can chdir to, possibly because it doesn't exist. |
| 427 | |
| 428 | =item Can't coerce %s to integer in %s |
| 429 | |
| 430 | (F) Certain types of SVs, in particular real symbol table entries |
| 431 | (typeglobs), can't be forced to stop being what they are. So you can't |
| 432 | say things like: |
| 433 | |
| 434 | *foo += 1; |
| 435 | |
| 436 | You CAN say |
| 437 | |
| 438 | $foo = *foo; |
| 439 | $foo += 1; |
| 440 | |
| 441 | but then $foo no longer contains a glob. |
| 442 | |
| 443 | =item Can't coerce %s to number in %s |
| 444 | |
| 445 | (F) Certain types of SVs, in particular real symbol table entries |
| 446 | (typeglobs), can't be forced to stop being what they are. |
| 447 | |
| 448 | =item Can't coerce %s to string in %s |
| 449 | |
| 450 | (F) Certain types of SVs, in particular real symbol table entries |
| 451 | (typeglobs), can't be forced to stop being what they are. |
| 452 | |
| 453 | =item Can't create pipe mailbox |
| 454 | |
| 455 | (P) An error peculiar to VMS. The process is suffering from exhausted quotas |
| 456 | or other plumbing problems. |
| 457 | |
| 458 | =item Can't declare %s in my |
| 459 | |
| 460 | (F) Only scalar, array, and hash variables may be declared as lexical variables. |
| 461 | They must have ordinary identifiers as names. |
| 462 | |
| 463 | =item Can't do inplace edit on %s: %s |
| 464 | |
| 465 | (S) The creation of the new file failed for the indicated reason. |
| 466 | |
| 467 | =item Can't do in-place edit without backup |
| 468 | |
| 469 | (F) You're on a system such as MSDOS that gets confused if you try reading |
| 470 | from a deleted (but still opened) file. You have to say B<-i>C<.bak>, or some |
| 471 | such. |
| 472 | |
| 473 | =item Can't do inplace edit: %s E<gt> 14 characters |
| 474 | |
| 475 | (S) There isn't enough room in the filename to make a backup name for the file. |
| 476 | |
| 477 | =item Can't do inplace edit: %s is not a regular file |
| 478 | |
| 479 | (S) You tried to use the B<-i> switch on a special file, such as a file in |
| 480 | /dev, or a FIFO. The file was ignored. |
| 481 | |
| 482 | =item Can't do setegid! |
| 483 | |
| 484 | (P) The setegid() call failed for some reason in the setuid emulator |
| 485 | of suidperl. |
| 486 | |
| 487 | =item Can't do seteuid! |
| 488 | |
| 489 | (P) The setuid emulator of suidperl failed for some reason. |
| 490 | |
| 491 | =item Can't do setuid |
| 492 | |
| 493 | (F) This typically means that ordinary perl tried to exec suidperl to |
| 494 | do setuid emulation, but couldn't exec it. It looks for a name of the |
| 495 | form sperl5.000 in the same directory that the perl executable resides |
| 496 | under the name perl5.000, typically /usr/local/bin on Unix machines. |
| 497 | If the file is there, check the execute permissions. If it isn't, ask |
| 498 | your sysadmin why he and/or she removed it. |
| 499 | |
| 500 | =item Can't do waitpid with flags |
| 501 | |
| 502 | (F) This machine doesn't have either waitpid() or wait4(), so only waitpid() |
| 503 | without flags is emulated. |
| 504 | |
| 505 | =item Can't do {n,m} with n E<gt> m |
| 506 | |
| 507 | (F) Minima must be less than or equal to maxima. If you really want |
| 508 | your regexp to match something 0 times, just put {0}. See L<perlre>. |
| 509 | |
| 510 | =item Can't emulate -%s on #! line |
| 511 | |
| 512 | (F) The #! line specifies a switch that doesn't make sense at this point. |
| 513 | For example, it'd be kind of silly to put a B<-x> on the #! line. |
| 514 | |
| 515 | =item Can't exec "%s": %s |
| 516 | |
| 517 | (W) An system(), exec(), or piped open call could not execute the named |
| 518 | program for the indicated reason. Typical reasons include: the permissions |
| 519 | were wrong on the file, the file wasn't found in C<$ENV{PATH}>, the |
| 520 | executable in question was compiled for another architecture, or the |
| 521 | #! line in a script points to an interpreter that can't be run for |
| 522 | similar reasons. (Or maybe your system doesn't support #! at all.) |
| 523 | |
| 524 | =item Can't exec %s |
| 525 | |
| 526 | (F) Perl was trying to execute the indicated program for you because that's |
| 527 | what the #! line said. If that's not what you wanted, you may need to |
| 528 | mention "perl" on the #! line somewhere. |
| 529 | |
| 530 | =item Can't execute %s |
| 531 | |
| 532 | (F) You used the B<-S> switch, but the script to execute could not be found |
| 533 | in the PATH, or at least not with the correct permissions. |
| 534 | |
| 535 | =item Can't find label %s |
| 536 | |
| 537 | (F) You said to goto a label that isn't mentioned anywhere that it's possible |
| 538 | for us to go to. See L<perlfunc/goto>. |
| 539 | |
| 540 | =item Can't find string terminator %s anywhere before EOF |
| 541 | |
| 542 | (F) Perl strings can stretch over multiple lines. This message means that |
| 543 | the closing delimiter was omitted. Because bracketed quotes count nesting |
| 544 | levels, the following is missing its final parenthesis: |
| 545 | |
| 546 | print q(The character '(' starts a side comment.) |
| 547 | |
| 548 | =item Can't fork |
| 549 | |
| 550 | (F) A fatal error occurred while trying to fork while opening a pipeline. |
| 551 | |
| 552 | =item Unsupported function fork |
| 553 | |
| 554 | (F) Your version of executable does not support forking. |
| 555 | |
| 556 | Note that under some systems, like OS/2, there may be different flavors of |
| 557 | Perl executables, some of which may support fork, some not. Try changing |
| 558 | the name you call Perl by to C<perl_>, C<perl__>, and so on. |
| 559 | |
| 560 | =item Can't get filespec - stale stat buffer? |
| 561 | |
| 562 | (S) A warning peculiar to VMS. This arises because of the difference between |
| 563 | access checks under VMS and under the Unix model Perl assumes. Under VMS, |
| 564 | access checks are done by filename, rather than by bits in the stat buffer, so |
| 565 | that ACLs and other protections can be taken into account. Unfortunately, Perl |
| 566 | assumes that the stat buffer contains all the necessary information, and passes |
| 567 | it, instead of the filespec, to the access checking routine. It will try to |
| 568 | retrieve the filespec using the device name and FID present in the stat buffer, |
| 569 | but this works only if you haven't made a subsequent call to the CRTL stat() |
| 570 | routine, because the device name is overwritten with each call. If this warning |
| 571 | appears, the name lookup failed, and the access checking routine gave up and |
| 572 | returned FALSE, just to be conservative. (Note: The access checking routine |
| 573 | knows about the Perl C<stat> operator and file tests, so you shouldn't ever |
| 574 | see this warning in response to a Perl command; it arises only if some internal |
| 575 | code takes stat buffers lightly.) |
| 576 | |
| 577 | =item Can't get pipe mailbox device name |
| 578 | |
| 579 | (P) An error peculiar to VMS. After creating a mailbox to act as a pipe, Perl |
| 580 | can't retrieve its name for later use. |
| 581 | |
| 582 | =item Can't get SYSGEN parameter value for MAXBUF |
| 583 | |
| 584 | (P) An error peculiar to VMS. Perl asked $GETSYI how big you want your |
| 585 | mailbox buffers to be, and didn't get an answer. |
| 586 | |
| 587 | =item Can't goto subroutine outside a subroutine |
| 588 | |
| 589 | (F) The deeply magical "goto subroutine" call can only replace one subroutine |
| 590 | call for another. It can't manufacture one out of whole cloth. In general |
| 591 | you should be calling it out of only an AUTOLOAD routine anyway. See |
| 592 | L<perlfunc/goto>. |
| 593 | |
| 594 | =item Can't localize a reference |
| 595 | |
| 596 | (F) You said something like C<local $$ref>, which is not allowed because |
| 597 | the compiler can't determine whether $ref will end up pointing to anything |
| 598 | with a symbol table entry, and a symbol table entry is necessary to |
| 599 | do a local. |
| 600 | |
| 601 | =item Can't localize lexical variable %s |
| 602 | |
| 603 | (F) You used local on a variable name that was previously declared as a |
| 604 | lexical variable using "my". This is not allowed. If you want to |
| 605 | localize a package variable of the same name, qualify it with the |
| 606 | package name. |
| 607 | |
| 608 | =item Can't locate %s in @INC |
| 609 | |
| 610 | (F) You said to do (or require, or use) a file that couldn't be found |
| 611 | in any of the libraries mentioned in @INC. Perhaps you need to set |
| 612 | the PERL5LIB environment variable to say where the extra library is, |
| 613 | or maybe the script needs to add the library name to @INC. Or maybe |
| 614 | you just misspelled the name of the file. See L<perlfunc/require>. |
| 615 | |
| 616 | =item Can't locate object method "%s" via package "%s" |
| 617 | |
| 618 | (F) You called a method correctly, and it correctly indicated a package |
| 619 | functioning as a class, but that package doesn't define that particular |
| 620 | method, nor does any of its base classes. See L<perlobj>. |
| 621 | |
| 622 | =item Can't locate package %s for @%s::ISA |
| 623 | |
| 624 | (W) The @ISA array contained the name of another package that doesn't seem |
| 625 | to exist. |
| 626 | |
| 627 | =item Can't mktemp() |
| 628 | |
| 629 | (F) The mktemp() routine failed for some reason while trying to process |
| 630 | a B<-e> switch. Maybe your /tmp partition is full, or clobbered. |
| 631 | |
| 632 | =item Can't modify %s in %s |
| 633 | |
| 634 | (F) You aren't allowed to assign to the item indicated, or otherwise try to |
| 635 | change it, such as with an auto-increment. |
| 636 | |
| 637 | =item Can't modify non-existent substring |
| 638 | |
| 639 | (P) The internal routine that does assignment to a substr() was handed |
| 640 | a NULL. |
| 641 | |
| 642 | =item Can't msgrcv to read-only var |
| 643 | |
| 644 | (F) The target of a msgrcv must be modifiable to be used as a receive |
| 645 | buffer. |
| 646 | |
| 647 | =item Can't open %s: %s |
| 648 | |
| 649 | (S) An inplace edit couldn't open the original file for the indicated reason. |
| 650 | Usually this is because you don't have read permission for the file. |
| 651 | |
| 652 | =item Can't open bidirectional pipe |
| 653 | |
| 654 | (W) You tried to say C<open(CMD, "|cmd|")>, which is not supported. You can |
| 655 | try any of several modules in the Perl library to do this, such as |
| 656 | IPC::Open2. Alternately, direct the pipe's output to a file using "E<gt>", |
| 657 | and then read it in under a different file handle. |
| 658 | |
| 659 | =item Can't open error file %s as stderr |
| 660 | |
| 661 | (F) An error peculiar to VMS. Perl does its own command line redirection, and |
| 662 | couldn't open the file specified after '2E<gt>' or '2E<gt>E<gt>' on the |
| 663 | command line for writing. |
| 664 | |
| 665 | =item Can't open input file %s as stdin |
| 666 | |
| 667 | (F) An error peculiar to VMS. Perl does its own command line redirection, and |
| 668 | couldn't open the file specified after 'E<lt>' on the command line for reading. |
| 669 | |
| 670 | =item Can't open output file %s as stdout |
| 671 | |
| 672 | (F) An error peculiar to VMS. Perl does its own command line redirection, and |
| 673 | couldn't open the file specified after 'E<gt>' or 'E<gt>E<gt>' on the command |
| 674 | line for writing. |
| 675 | |
| 676 | =item Can't open output pipe (name: %s) |
| 677 | |
| 678 | (P) An error peculiar to VMS. Perl does its own command line redirection, and |
| 679 | couldn't open the pipe into which to send data destined for stdout. |
| 680 | |
| 681 | =item Can't open perl script "%s": %s |
| 682 | |
| 683 | (F) The script you specified can't be opened for the indicated reason. |
| 684 | |
| 685 | =item Can't rename %s to %s: %s, skipping file |
| 686 | |
| 687 | (S) The rename done by the B<-i> switch failed for some reason, probably because |
| 688 | you don't have write permission to the directory. |
| 689 | |
| 690 | =item Can't reopen input pipe (name: %s) in binary mode |
| 691 | |
| 692 | (P) An error peculiar to VMS. Perl thought stdin was a pipe, and tried to |
| 693 | reopen it to accept binary data. Alas, it failed. |
| 694 | |
| 695 | =item Can't reswap uid and euid |
| 696 | |
| 697 | (P) The setreuid() call failed for some reason in the setuid emulator |
| 698 | of suidperl. |
| 699 | |
| 700 | =item Can't return outside a subroutine |
| 701 | |
| 702 | (F) The return statement was executed in mainline code, that is, where |
| 703 | there was no subroutine call to return out of. See L<perlsub>. |
| 704 | |
| 705 | =item Can't stat script "%s" |
| 706 | |
| 707 | (P) For some reason you can't fstat() the script even though you have |
| 708 | it open already. Bizarre. |
| 709 | |
| 710 | =item Can't swap uid and euid |
| 711 | |
| 712 | (P) The setreuid() call failed for some reason in the setuid emulator |
| 713 | of suidperl. |
| 714 | |
| 715 | =item Can't take log of %g |
| 716 | |
| 717 | (F) Logarithms are defined on only positive real numbers. |
| 718 | |
| 719 | =item Can't take sqrt of %g |
| 720 | |
| 721 | (F) For ordinary real numbers, you can't take the square root of a |
| 722 | negative number. There's a Complex package available for Perl, though, |
| 723 | if you really want to do that. |
| 724 | |
| 725 | =item Can't undef active subroutine |
| 726 | |
| 727 | (F) You can't undefine a routine that's currently running. You can, |
| 728 | however, redefine it while it's running, and you can even undef the |
| 729 | redefined subroutine while the old routine is running. Go figure. |
| 730 | |
| 731 | =item Can't unshift |
| 732 | |
| 733 | (F) You tried to unshift an "unreal" array that can't be unshifted, such |
| 734 | as the main Perl stack. |
| 735 | |
| 736 | =item Can't upgrade that kind of scalar |
| 737 | |
| 738 | (P) The internal sv_upgrade routine adds "members" to an SV, making |
| 739 | it into a more specialized kind of SV. The top several SV types are |
| 740 | so specialized, however, that they cannot be interconverted. This |
| 741 | message indicates that such a conversion was attempted. |
| 742 | |
| 743 | =item Can't upgrade to undef |
| 744 | |
| 745 | (P) The undefined SV is the bottom of the totem pole, in the scheme |
| 746 | of upgradability. Upgrading to undef indicates an error in the |
| 747 | code calling sv_upgrade. |
| 748 | |
| 749 | =item Can't use "my %s" in sort comparison |
| 750 | |
| 751 | (F) The global variables $a and $b are reserved for sort comparisons. |
| 752 | You mentioned $a or $b in the same line as the E<lt>=E<gt> or cmp operator, |
| 753 | and the variable had earlier been declared as a lexical variable. |
| 754 | Either qualify the sort variable with the package name, or rename the |
| 755 | lexical variable. |
| 756 | |
| 757 | =item Can't use %s for loop variable |
| 758 | |
| 759 | (F) Only a simple scalar variable may be used as a loop variable on a foreach. |
| 760 | |
| 761 | =item Can't use %s ref as %s ref |
| 762 | |
| 763 | (F) You've mixed up your reference types. You have to dereference a |
| 764 | reference of the type needed. You can use the ref() function to |
| 765 | test the type of the reference, if need be. |
| 766 | |
| 767 | =item Can't use \1 to mean $1 in expression |
| 768 | |
| 769 | (W) In an ordinary expression, backslash is a unary operator that creates |
| 770 | a reference to its argument. The use of backslash to indicate a backreference |
| 771 | to a matched substring is valid only as part of a regular expression pattern. |
| 772 | Trying to do this in ordinary Perl code produces a value that prints |
| 773 | out looking like SCALAR(0xdecaf). Use the $1 form instead. |
| 774 | |
| 775 | =item Can't use bareword ("%s") as %s ref while \"strict refs\" in use |
| 776 | |
| 777 | (F) Only hard references are allowed by "strict refs". Symbolic references |
| 778 | are disallowed. See L<perlref>. |
| 779 | |
| 780 | =item Can't use string ("%s") as %s ref while "strict refs" in use |
| 781 | |
| 782 | (F) Only hard references are allowed by "strict refs". Symbolic references |
| 783 | are disallowed. See L<perlref>. |
| 784 | |
| 785 | =item Can't use an undefined value as %s reference |
| 786 | |
| 787 | (F) A value used as either a hard reference or a symbolic reference must |
| 788 | be a defined value. This helps to de-lurk some insidious errors. |
| 789 | |
| 790 | =item Can't use global %s in "my" |
| 791 | |
| 792 | (F) You tried to declare a magical variable as a lexical variable. This is |
| 793 | not allowed, because the magic can be tied to only one location (namely |
| 794 | the global variable) and it would be incredibly confusing to have |
| 795 | variables in your program that looked like magical variables but |
| 796 | weren't. |
| 797 | |
| 798 | =item Can't use subscript on %s |
| 799 | |
| 800 | (F) The compiler tried to interpret a bracketed expression as a |
| 801 | subscript. But to the left of the brackets was an expression that |
| 802 | didn't look like an array reference, or anything else subscriptable. |
| 803 | |
| 804 | =item Can't write to temp file for B<-e>: %s |
| 805 | |
| 806 | (F) The write routine failed for some reason while trying to process |
| 807 | a B<-e> switch. Maybe your /tmp partition is full, or clobbered. |
| 808 | |
| 809 | =item Can't x= to read-only value |
| 810 | |
| 811 | (F) You tried to repeat a constant value (often the undefined value) with |
| 812 | an assignment operator, which implies modifying the value itself. |
| 813 | Perhaps you need to copy the value to a temporary, and repeat that. |
| 814 | |
| 815 | =item Cannot open temporary file |
| 816 | |
| 817 | (F) The create routine failed for some reason while trying to process |
| 818 | a B<-e> switch. Maybe your /tmp partition is full, or clobbered. |
| 819 | |
| 820 | =item Cannot resolve method `%s' overloading `%s' in package `%s' |
| 821 | |
| 822 | (F|P) Error resolving overloading specified by a method name (as |
| 823 | opposed to a subroutine reference): no such method callable via the |
| 824 | package. If method name is C<???>, this is an internal error. |
| 825 | |
| 826 | =item chmod: mode argument is missing initial 0 |
| 827 | |
| 828 | (W) A novice will sometimes say |
| 829 | |
| 830 | chmod 777, $filename |
| 831 | |
| 832 | not realizing that 777 will be interpreted as a decimal number, equivalent |
| 833 | to 01411. Octal constants are introduced with a leading 0 in Perl, as in C. |
| 834 | |
| 835 | =item Close on unopened file E<lt>%sE<gt> |
| 836 | |
| 837 | (W) You tried to close a filehandle that was never opened. |
| 838 | |
| 839 | =item connect() on closed fd |
| 840 | |
| 841 | (W) You tried to do a connect on a closed socket. Did you forget to check |
| 842 | the return value of your socket() call? See L<perlfunc/connect>. |
| 843 | |
| 844 | =item Constant subroutine %s redefined |
| 845 | |
| 846 | (S) You redefined a subroutine which had previously been eligible for |
| 847 | inlining. See L<perlsub/"Constant Functions"> for commentary and |
| 848 | workarounds. |
| 849 | |
| 850 | =item Constant subroutine %s undefined |
| 851 | |
| 852 | (S) You undefined a subroutine which had previously been eligible for |
| 853 | inlining. See L<perlsub/"Constant Functions"> for commentary and |
| 854 | workarounds. |
| 855 | |
| 856 | =item Copy method did not return a reference |
| 857 | |
| 858 | (F) The method which overloads "=" is buggy. See L<overload/Copy Constructor>. |
| 859 | |
| 860 | =item Corrupt malloc ptr 0x%lx at 0x%lx |
| 861 | |
| 862 | (P) The malloc package that comes with Perl had an internal failure. |
| 863 | |
| 864 | =item corrupted regexp pointers |
| 865 | |
| 866 | (P) The regular expression engine got confused by what the regular |
| 867 | expression compiler gave it. |
| 868 | |
| 869 | =item corrupted regexp program |
| 870 | |
| 871 | (P) The regular expression engine got passed a regexp program without |
| 872 | a valid magic number. |
| 873 | |
| 874 | =item Deep recursion on subroutine "%s" |
| 875 | |
| 876 | (W) This subroutine has called itself (directly or indirectly) 100 |
| 877 | times than it has returned. This probably indicates an infinite |
| 878 | recursion, unless you're writing strange benchmark programs, in which |
| 879 | case it indicates something else. |
| 880 | |
| 881 | =item Did you mean &%s instead? |
| 882 | |
| 883 | (W) You probably referred to an imported subroutine &FOO as $FOO or some such. |
| 884 | |
| 885 | =item Did you mean $ or @ instead of %? |
| 886 | |
| 887 | (W) You probably said %hash{$key} when you meant $hash{$key} or @hash{@keys}. |
| 888 | On the other hand, maybe you just meant %hash and got carried away. |
| 889 | |
| 890 | =item Died |
| 891 | |
| 892 | (F) You passed die() an empty string (the equivalent of C<die "">) or |
| 893 | you called it with no args and both C<$@> and C<$_> were empty. |
| 894 | |
| 895 | =item Do you need to pre-declare %s? |
| 896 | |
| 897 | (S) This is an educated guess made in conjunction with the message "%s |
| 898 | found where operator expected". It often means a subroutine or module |
| 899 | name is being referenced that hasn't been declared yet. This may be |
| 900 | because of ordering problems in your file, or because of a missing |
| 901 | "sub", "package", "require", or "use" statement. If you're |
| 902 | referencing something that isn't defined yet, you don't actually have |
| 903 | to define the subroutine or package before the current location. You |
| 904 | can use an empty "sub foo;" or "package FOO;" to enter a "forward" |
| 905 | declaration. |
| 906 | |
| 907 | =item Don't know how to handle magic of type '%s' |
| 908 | |
| 909 | (P) The internal handling of magical variables has been cursed. |
| 910 | |
| 911 | =item do_study: out of memory |
| 912 | |
| 913 | (P) This should have been caught by safemalloc() instead. |
| 914 | |
| 915 | =item Duplicate free() ignored |
| 916 | |
| 917 | (S) An internal routine called free() on something that had already |
| 918 | been freed. |
| 919 | |
| 920 | =item elseif should be elsif |
| 921 | |
| 922 | (S) There is no keyword "elseif" in Perl because Larry thinks it's |
| 923 | ugly. Your code will be interpreted as an attempt to call a method |
| 924 | named "elseif" for the class returned by the following block. This is |
| 925 | unlikely to be what you want. |
| 926 | |
| 927 | =item END failed--cleanup aborted |
| 928 | |
| 929 | (F) An untrapped exception was raised while executing an END subroutine. |
| 930 | The interpreter is immediately exited. |
| 931 | |
| 932 | =item Error converting file specification %s |
| 933 | |
| 934 | (F) An error peculiar to VMS. Because Perl may have to deal with file |
| 935 | specifications in either VMS or Unix syntax, it converts them to a |
| 936 | single form when it must operate on them directly. Either you've |
| 937 | passed an invalid file specification to Perl, or you've found a |
| 938 | case the conversion routines don't handle. Drat. |
| 939 | |
| 940 | =item Execution of %s aborted due to compilation errors |
| 941 | |
| 942 | (F) The final summary message when a Perl compilation fails. |
| 943 | |
| 944 | =item Exiting eval via %s |
| 945 | |
| 946 | (W) You are exiting an eval by unconventional means, such as |
| 947 | a goto, or a loop control statement. |
| 948 | |
| 949 | =item Exiting pseudo-block via %s |
| 950 | |
| 951 | (W) You are exiting a rather special block construct (like a sort block or |
| 952 | subroutine) by unconventional means, such as a goto, or a loop control |
| 953 | statement. See L<perlfunc/sort>. |
| 954 | |
| 955 | =item Exiting subroutine via %s |
| 956 | |
| 957 | (W) You are exiting a subroutine by unconventional means, such as |
| 958 | a goto, or a loop control statement. |
| 959 | |
| 960 | =item Exiting substitution via %s |
| 961 | |
| 962 | (W) You are exiting a substitution by unconventional means, such as |
| 963 | a return, a goto, or a loop control statement. |
| 964 | |
| 965 | =item Fatal VMS error at %s, line %d |
| 966 | |
| 967 | (P) An error peculiar to VMS. Something untoward happened in a VMS system |
| 968 | service or RTL routine; Perl's exit status should provide more details. The |
| 969 | filename in "at %s" and the line number in "line %d" tell you which section of |
| 970 | the Perl source code is distressed. |
| 971 | |
| 972 | =item fcntl is not implemented |
| 973 | |
| 974 | (F) Your machine apparently doesn't implement fcntl(). What is this, a |
| 975 | PDP-11 or something? |
| 976 | |
| 977 | =item Filehandle %s never opened |
| 978 | |
| 979 | (W) An I/O operation was attempted on a filehandle that was never initialized. |
| 980 | You need to do an open() or a socket() call, or call a constructor from |
| 981 | the FileHandle package. |
| 982 | |
| 983 | =item Filehandle %s opened for only input |
| 984 | |
| 985 | (W) You tried to write on a read-only filehandle. If you |
| 986 | intended it to be a read-write filehandle, you needed to open it with |
| 987 | "+E<lt>" or "+E<gt>" or "+E<gt>E<gt>" instead of with "E<lt>" or nothing. If |
| 988 | you intended only to write the file, use "E<gt>" or "E<gt>E<gt>". See |
| 989 | L<perlfunc/open>. |
| 990 | |
| 991 | =item Filehandle opened for only input |
| 992 | |
| 993 | (W) You tried to write on a read-only filehandle. If you |
| 994 | intended it to be a read-write filehandle, you needed to open it with |
| 995 | "+E<lt>" or "+E<gt>" or "+E<gt>E<gt>" instead of with "E<lt>" or nothing. If |
| 996 | you intended only to write the file, use "E<gt>" or "E<gt>E<gt>". See |
| 997 | L<perlfunc/open>. |
| 998 | |
| 999 | =item Final $ should be \$ or $name |
| 1000 | |
| 1001 | (F) You must now decide whether the final $ in a string was meant to be |
| 1002 | a literal dollar sign, or was meant to introduce a variable name |
| 1003 | that happens to be missing. So you have to put either the backslash or |
| 1004 | the name. |
| 1005 | |
| 1006 | =item Final @ should be \@ or @name |
| 1007 | |
| 1008 | (F) You must now decide whether the final @ in a string was meant to be |
| 1009 | a literal "at" sign, or was meant to introduce a variable name |
| 1010 | that happens to be missing. So you have to put either the backslash or |
| 1011 | the name. |
| 1012 | |
| 1013 | =item Format %s redefined |
| 1014 | |
| 1015 | (W) You redefined a format. To suppress this warning, say |
| 1016 | |
| 1017 | { |
| 1018 | local $^W = 0; |
| 1019 | eval "format NAME =..."; |
| 1020 | } |
| 1021 | |
| 1022 | =item Format not terminated |
| 1023 | |
| 1024 | (F) A format must be terminated by a line with a solitary dot. Perl got |
| 1025 | to the end of your file without finding such a line. |
| 1026 | |
| 1027 | =item Found = in conditional, should be == |
| 1028 | |
| 1029 | (W) You said |
| 1030 | |
| 1031 | if ($foo = 123) |
| 1032 | |
| 1033 | when you meant |
| 1034 | |
| 1035 | if ($foo == 123) |
| 1036 | |
| 1037 | (or something like that). |
| 1038 | |
| 1039 | =item gdbm store returned %d, errno %d, key "%s" |
| 1040 | |
| 1041 | (S) A warning from the GDBM_File extension that a store failed. |
| 1042 | |
| 1043 | =item gethostent not implemented |
| 1044 | |
| 1045 | (F) Your C library apparently doesn't implement gethostent(), probably |
| 1046 | because if it did, it'd feel morally obligated to return every hostname |
| 1047 | on the Internet. |
| 1048 | |
| 1049 | =item get{sock,peer}name() on closed fd |
| 1050 | |
| 1051 | (W) You tried to get a socket or peer socket name on a closed socket. |
| 1052 | Did you forget to check the return value of your socket() call? |
| 1053 | |
| 1054 | =item getpwnam returned invalid UIC %#o for user "%s" |
| 1055 | |
| 1056 | (S) A warning peculiar to VMS. The call to C<sys$getuai> underlying the |
| 1057 | C<getpwnam> operator returned an invalid UIC. |
| 1058 | |
| 1059 | |
| 1060 | =item Glob not terminated |
| 1061 | |
| 1062 | (F) The lexer saw a left angle bracket in a place where it was expecting |
| 1063 | a term, so it's looking for the corresponding right angle bracket, and not |
| 1064 | finding it. Chances are you left some needed parentheses out earlier in |
| 1065 | the line, and you really meant a "less than". |
| 1066 | |
| 1067 | =item Global symbol "%s" requires explicit package name |
| 1068 | |
| 1069 | (F) You've said "use strict vars", which indicates that all variables must |
| 1070 | either be lexically scoped (using "my"), or explicitly qualified to |
| 1071 | say which package the global variable is in (using "::"). |
| 1072 | |
| 1073 | =item goto must have label |
| 1074 | |
| 1075 | (F) Unlike with "next" or "last", you're not allowed to goto an |
| 1076 | unspecified destination. See L<perlfunc/goto>. |
| 1077 | |
| 1078 | =item Had to create %s unexpectedly |
| 1079 | |
| 1080 | (S) A routine asked for a symbol from a symbol table that ought to have |
| 1081 | existed already, but for some reason it didn't, and had to be created on |
| 1082 | an emergency basis to prevent a core dump. |
| 1083 | |
| 1084 | =item Hash %%s missing the % in argument %d of %s() |
| 1085 | |
| 1086 | (D) Really old Perl let you omit the % on hash names in some spots. This |
| 1087 | is now heavily deprecated. |
| 1088 | |
| 1089 | =item Ill-formed logical name |%s| in prime_env_iter |
| 1090 | |
| 1091 | (W) A warning peculiar to VMS. A logical name was encountered when preparing |
| 1092 | to iterate over %ENV which violates the syntactic rules governing logical |
| 1093 | names. Because it cannot be translated normally, it is skipped, and will not |
| 1094 | appear in %ENV. This may be a benign occurrence, as some software packages |
| 1095 | might directly modify logical name tables and introduce non-standard names, |
| 1096 | or it may indicate that a logical name table has been corrupted. |
| 1097 | |
| 1098 | =item Illegal character %s (carriage return) |
| 1099 | |
| 1100 | (F) A carriage return character was found in the input. This is an |
| 1101 | error, and not a warning, because carriage return characters can break |
| 1102 | here documents (e.g. C<print E<lt>E<lt>EOF;>). Note that Perl always |
| 1103 | opens scripts in text mode, so this error should only occur in C<eval>. |
| 1104 | |
| 1105 | =item Illegal division by zero |
| 1106 | |
| 1107 | (F) You tried to divide a number by 0. Either something was wrong in your |
| 1108 | logic, or you need to put a conditional in to guard against meaningless input. |
| 1109 | |
| 1110 | =item Illegal modulus zero |
| 1111 | |
| 1112 | (F) You tried to divide a number by 0 to get the remainder. Most numbers |
| 1113 | don't take to this kindly. |
| 1114 | |
| 1115 | =item Illegal octal digit |
| 1116 | |
| 1117 | (F) You used an 8 or 9 in a octal number. |
| 1118 | |
| 1119 | =item Illegal octal digit ignored |
| 1120 | |
| 1121 | (W) You may have tried to use an 8 or 9 in a octal number. Interpretation |
| 1122 | of the octal number stopped before the 8 or 9. |
| 1123 | |
| 1124 | =item In string, @%s now must be written as \@%s |
| 1125 | |
| 1126 | (F) It used to be that Perl would try to guess whether you wanted an |
| 1127 | array interpolated or a literal @. It did this when the string was first |
| 1128 | used at runtime. Now strings are parsed at compile time, and ambiguous |
| 1129 | instances of @ must be disambiguated, either by prepending a backslash to |
| 1130 | indicate a literal, or by declaring (or using) the array within the |
| 1131 | program before the string (lexically). (Someday it will simply assume |
| 1132 | that an unbackslashed @ interpolates an array.) |
| 1133 | |
| 1134 | =item Insecure dependency in %s |
| 1135 | |
| 1136 | (F) You tried to do something that the tainting mechanism didn't like. |
| 1137 | The tainting mechanism is turned on when you're running setuid or setgid, |
| 1138 | or when you specify B<-T> to turn it on explicitly. The tainting mechanism |
| 1139 | labels all data that's derived directly or indirectly from the user, |
| 1140 | who is considered to be unworthy of your trust. If any such data is |
| 1141 | used in a "dangerous" operation, you get this error. See L<perlsec> |
| 1142 | for more information. |
| 1143 | |
| 1144 | =item Insecure directory in %s |
| 1145 | |
| 1146 | (F) You can't use system(), exec(), or a piped open in a setuid or setgid |
| 1147 | script if C<$ENV{PATH}> contains a directory that is writable by the world. |
| 1148 | See L<perlsec>. |
| 1149 | |
| 1150 | =item Insecure PATH |
| 1151 | |
| 1152 | (F) You can't use system(), exec(), or a piped open in a setuid or |
| 1153 | setgid script if C<$ENV{PATH}> is derived from data supplied (or |
| 1154 | potentially supplied) by the user. The script must set the path to a |
| 1155 | known value, using trustworthy data. See L<perlsec>. |
| 1156 | |
| 1157 | =item Integer overflow in hex number |
| 1158 | |
| 1159 | (S) The literal hex number you have specified is too big for your |
| 1160 | architecture. On a 32-bit architecture the largest hex literal is |
| 1161 | 0xFFFFFFFF. |
| 1162 | |
| 1163 | =item Integer overflow in octal number |
| 1164 | |
| 1165 | (S) The literal octal number you have specified is too big for your |
| 1166 | architecture. On a 32-bit architecture the largest octal literal is |
| 1167 | 037777777777. |
| 1168 | |
| 1169 | =item Internal inconsistency in tracking vforks |
| 1170 | |
| 1171 | (S) A warning peculiar to VMS. Perl keeps track of the number |
| 1172 | of times you've called C<fork> and C<exec>, to determine |
| 1173 | whether the current call to C<exec> should affect the current |
| 1174 | script or a subprocess (see L<perlvms/exec>). Somehow, this count |
| 1175 | has become scrambled, so Perl is making a guess and treating |
| 1176 | this C<exec> as a request to terminate the Perl script |
| 1177 | and execute the specified command. |
| 1178 | |
| 1179 | =item internal disaster in regexp |
| 1180 | |
| 1181 | (P) Something went badly wrong in the regular expression parser. |
| 1182 | |
| 1183 | =item internal urp in regexp at /%s/ |
| 1184 | |
| 1185 | (P) Something went badly awry in the regular expression parser. |
| 1186 | |
| 1187 | =item invalid [] range in regexp |
| 1188 | |
| 1189 | (F) The range specified in a character class had a minimum character |
| 1190 | greater than the maximum character. See L<perlre>. |
| 1191 | |
| 1192 | =item ioctl is not implemented |
| 1193 | |
| 1194 | (F) Your machine apparently doesn't implement ioctl(), which is pretty |
| 1195 | strange for a machine that supports C. |
| 1196 | |
| 1197 | =item junk on end of regexp |
| 1198 | |
| 1199 | (P) The regular expression parser is confused. |
| 1200 | |
| 1201 | =item Label not found for "last %s" |
| 1202 | |
| 1203 | (F) You named a loop to break out of, but you're not currently in a |
| 1204 | loop of that name, not even if you count where you were called from. |
| 1205 | See L<perlfunc/last>. |
| 1206 | |
| 1207 | =item Label not found for "next %s" |
| 1208 | |
| 1209 | (F) You named a loop to continue, but you're not currently in a loop of |
| 1210 | that name, not even if you count where you were called from. See |
| 1211 | L<perlfunc/last>. |
| 1212 | |
| 1213 | =item Label not found for "redo %s" |
| 1214 | |
| 1215 | (F) You named a loop to restart, but you're not currently in a loop of |
| 1216 | that name, not even if you count where you were called from. See |
| 1217 | L<perlfunc/last>. |
| 1218 | |
| 1219 | =item listen() on closed fd |
| 1220 | |
| 1221 | (W) You tried to do a listen on a closed socket. Did you forget to check |
| 1222 | the return value of your socket() call? See L<perlfunc/listen>. |
| 1223 | |
| 1224 | =item Method for operation %s not found in package %s during blessing |
| 1225 | |
| 1226 | (F) An attempt was made to specify an entry in an overloading table that |
| 1227 | doesn't resolve to a valid subroutine. See L<overload>. |
| 1228 | |
| 1229 | =item Might be a runaway multi-line %s string starting on line %d |
| 1230 | |
| 1231 | (S) An advisory indicating that the previous error may have been caused |
| 1232 | by a missing delimiter on a string or pattern, because it eventually |
| 1233 | ended earlier on the current line. |
| 1234 | |
| 1235 | =item Misplaced _ in number |
| 1236 | |
| 1237 | (W) An underline in a decimal constant wasn't on a 3-digit boundary. |
| 1238 | |
| 1239 | =item Missing $ on loop variable |
| 1240 | |
| 1241 | (F) Apparently you've been programming in B<csh> too much. Variables are always |
| 1242 | mentioned with the $ in Perl, unlike in the shells, where it can vary from |
| 1243 | one line to the next. |
| 1244 | |
| 1245 | =item Missing comma after first argument to %s function |
| 1246 | |
| 1247 | (F) While certain functions allow you to specify a filehandle or an |
| 1248 | "indirect object" before the argument list, this ain't one of them. |
| 1249 | |
| 1250 | =item Missing operator before %s? |
| 1251 | |
| 1252 | (S) This is an educated guess made in conjunction with the message "%s |
| 1253 | found where operator expected". Often the missing operator is a comma. |
| 1254 | |
| 1255 | =item Missing right bracket |
| 1256 | |
| 1257 | (F) The lexer counted more opening curly brackets (braces) than closing ones. |
| 1258 | As a general rule, you'll find it's missing near the place you were last |
| 1259 | editing. |
| 1260 | |
| 1261 | =item Missing semicolon on previous line? |
| 1262 | |
| 1263 | (S) This is an educated guess made in conjunction with the message "%s |
| 1264 | found where operator expected". Don't automatically put a semicolon on |
| 1265 | the previous line just because you saw this message. |
| 1266 | |
| 1267 | =item Modification of a read-only value attempted |
| 1268 | |
| 1269 | (F) You tried, directly or indirectly, to change the value of a |
| 1270 | constant. You didn't, of course, try "2 = 1", because the compiler |
| 1271 | catches that. But an easy way to do the same thing is: |
| 1272 | |
| 1273 | sub mod { $_[0] = 1 } |
| 1274 | mod(2); |
| 1275 | |
| 1276 | Another way is to assign to a substr() that's off the end of the string. |
| 1277 | |
| 1278 | =item Modification of non-creatable array value attempted, subscript %d |
| 1279 | |
| 1280 | (F) You tried to make an array value spring into existence, and the |
| 1281 | subscript was probably negative, even counting from end of the array |
| 1282 | backwards. |
| 1283 | |
| 1284 | =item Modification of non-creatable hash value attempted, subscript "%s" |
| 1285 | |
| 1286 | (F) You tried to make a hash value spring into existence, and it couldn't |
| 1287 | be created for some peculiar reason. |
| 1288 | |
| 1289 | =item Module name must be constant |
| 1290 | |
| 1291 | (F) Only a bare module name is allowed as the first argument to a "use". |
| 1292 | |
| 1293 | =item msg%s not implemented |
| 1294 | |
| 1295 | (F) You don't have System V message IPC on your system. |
| 1296 | |
| 1297 | =item Multidimensional syntax %s not supported |
| 1298 | |
| 1299 | (W) Multidimensional arrays aren't written like C<$foo[1,2,3]>. They're written |
| 1300 | like C<$foo[1][2][3]>, as in C. |
| 1301 | |
| 1302 | =item Name "%s::%s" used only once: possible typo |
| 1303 | |
| 1304 | (W) Typographical errors often show up as unique variable names. If you |
| 1305 | had a good reason for having a unique name, then just mention it |
| 1306 | again somehow to suppress the message (the C<use vars> pragma is |
| 1307 | provided for just this purpose). |
| 1308 | |
| 1309 | =item Negative length |
| 1310 | |
| 1311 | (F) You tried to do a read/write/send/recv operation with a buffer length |
| 1312 | that is less than 0. This is difficult to imagine. |
| 1313 | |
| 1314 | =item nested *?+ in regexp |
| 1315 | |
| 1316 | (F) You can't quantify a quantifier without intervening parentheses. So |
| 1317 | things like ** or +* or ?* are illegal. |
| 1318 | |
| 1319 | Note, however, that the minimal matching quantifiers, C<*?>, C<+?>, and C<??> appear |
| 1320 | to be nested quantifiers, but aren't. See L<perlre>. |
| 1321 | |
| 1322 | =item No #! line |
| 1323 | |
| 1324 | (F) The setuid emulator requires that scripts have a well-formed #! line |
| 1325 | even on machines that don't support the #! construct. |
| 1326 | |
| 1327 | =item No %s allowed while running setuid |
| 1328 | |
| 1329 | (F) Certain operations are deemed to be too insecure for a setuid or setgid |
| 1330 | script to even be allowed to attempt. Generally speaking there will be |
| 1331 | another way to do what you want that is, if not secure, at least securable. |
| 1332 | See L<perlsec>. |
| 1333 | |
| 1334 | =item No B<-e> allowed in setuid scripts |
| 1335 | |
| 1336 | (F) A setuid script can't be specified by the user. |
| 1337 | |
| 1338 | =item No comma allowed after %s |
| 1339 | |
| 1340 | (F) A list operator that has a filehandle or "indirect object" is not |
| 1341 | allowed to have a comma between that and the following arguments. |
| 1342 | Otherwise it'd be just another one of the arguments. |
| 1343 | |
| 1344 | One possible cause for this is that you expected to have imported a |
| 1345 | constant to your name space with B<use> or B<import> while no such |
| 1346 | importing took place, it may for example be that your operating system |
| 1347 | does not support that particular constant. Hopefully you did use an |
| 1348 | explicit import list for the constants you expect to see, please see |
| 1349 | L<perlfunc/use> and L<perlfunc/import>. While an explicit import list |
| 1350 | would probably have caught this error earlier it naturally does not |
| 1351 | remedy the fact that your operating system still does not support that |
| 1352 | constant. Maybe you have a typo in the constants of the symbol import |
| 1353 | list of B<use> or B<import> or in the constant name at the line where |
| 1354 | this error was triggered? |
| 1355 | |
| 1356 | =item No command into which to pipe on command line |
| 1357 | |
| 1358 | (F) An error peculiar to VMS. Perl handles its own command line redirection, |
| 1359 | and found a '|' at the end of the command line, so it doesn't know whither you |
| 1360 | want to pipe the output from this command. |
| 1361 | |
| 1362 | =item No DB::DB routine defined |
| 1363 | |
| 1364 | (F) The currently executing code was compiled with the B<-d> switch, |
| 1365 | but for some reason the perl5db.pl file (or some facsimile thereof) |
| 1366 | didn't define a routine to be called at the beginning of each |
| 1367 | statement. Which is odd, because the file should have been required |
| 1368 | automatically, and should have blown up the require if it didn't parse |
| 1369 | right. |
| 1370 | |
| 1371 | =item No dbm on this machine |
| 1372 | |
| 1373 | (P) This is counted as an internal error, because every machine should |
| 1374 | supply dbm nowadays, because Perl comes with SDBM. See L<SDBM_File>. |
| 1375 | |
| 1376 | =item No DBsub routine |
| 1377 | |
| 1378 | (F) The currently executing code was compiled with the B<-d> switch, |
| 1379 | but for some reason the perl5db.pl file (or some facsimile thereof) |
| 1380 | didn't define a DB::sub routine to be called at the beginning of each |
| 1381 | ordinary subroutine call. |
| 1382 | |
| 1383 | =item No error file after 2E<gt> or 2E<gt>E<gt> on command line |
| 1384 | |
| 1385 | (F) An error peculiar to VMS. Perl handles its own command line redirection, |
| 1386 | and found a '2E<gt>' or a '2E<gt>E<gt>' on the command line, but can't find |
| 1387 | the name of the file to which to write data destined for stderr. |
| 1388 | |
| 1389 | =item No input file after E<lt> on command line |
| 1390 | |
| 1391 | (F) An error peculiar to VMS. Perl handles its own command line redirection, |
| 1392 | and found a 'E<lt>' on the command line, but can't find the name of the file |
| 1393 | from which to read data for stdin. |
| 1394 | |
| 1395 | =item No output file after E<gt> on command line |
| 1396 | |
| 1397 | (F) An error peculiar to VMS. Perl handles its own command line redirection, |
| 1398 | and found a lone 'E<gt>' at the end of the command line, so it doesn't know |
| 1399 | whither you wanted to redirect stdout. |
| 1400 | |
| 1401 | =item No output file after E<gt> or E<gt>E<gt> on command line |
| 1402 | |
| 1403 | (F) An error peculiar to VMS. Perl handles its own command line redirection, |
| 1404 | and found a 'E<gt>' or a 'E<gt>E<gt>' on the command line, but can't find the |
| 1405 | name of the file to which to write data destined for stdout. |
| 1406 | |
| 1407 | =item No Perl script found in input |
| 1408 | |
| 1409 | (F) You called C<perl -x>, but no line was found in the file beginning |
| 1410 | with #! and containing the word "perl". |
| 1411 | |
| 1412 | =item No setregid available |
| 1413 | |
| 1414 | (F) Configure didn't find anything resembling the setregid() call for |
| 1415 | your system. |
| 1416 | |
| 1417 | =item No setreuid available |
| 1418 | |
| 1419 | (F) Configure didn't find anything resembling the setreuid() call for |
| 1420 | your system. |
| 1421 | |
| 1422 | =item No space allowed after B<-I> |
| 1423 | |
| 1424 | (F) The argument to B<-I> must follow the B<-I> immediately with no |
| 1425 | intervening space. |
| 1426 | |
| 1427 | =item No such pipe open |
| 1428 | |
| 1429 | (P) An error peculiar to VMS. The internal routine my_pclose() tried to |
| 1430 | close a pipe which hadn't been opened. This should have been caught earlier as |
| 1431 | an attempt to close an unopened filehandle. |
| 1432 | |
| 1433 | =item No such signal: SIG%s |
| 1434 | |
| 1435 | (W) You specified a signal name as a subscript to %SIG that was not recognized. |
| 1436 | Say C<kill -l> in your shell to see the valid signal names on your system. |
| 1437 | |
| 1438 | =item Not a CODE reference |
| 1439 | |
| 1440 | (F) Perl was trying to evaluate a reference to a code value (that is, a |
| 1441 | subroutine), but found a reference to something else instead. You can |
| 1442 | use the ref() function to find out what kind of ref it really was. |
| 1443 | See also L<perlref>. |
| 1444 | |
| 1445 | =item Not a format reference |
| 1446 | |
| 1447 | (F) I'm not sure how you managed to generate a reference to an anonymous |
| 1448 | format, but this indicates you did, and that it didn't exist. |
| 1449 | |
| 1450 | =item Not a GLOB reference |
| 1451 | |
| 1452 | (F) Perl was trying to evaluate a reference to a "typeglob" (that is, |
| 1453 | a symbol table entry that looks like C<*foo>), but found a reference to |
| 1454 | something else instead. You can use the ref() function to find out |
| 1455 | what kind of ref it really was. See L<perlref>. |
| 1456 | |
| 1457 | =item Not a HASH reference |
| 1458 | |
| 1459 | (F) Perl was trying to evaluate a reference to a hash value, but |
| 1460 | found a reference to something else instead. You can use the ref() |
| 1461 | function to find out what kind of ref it really was. See L<perlref>. |
| 1462 | |
| 1463 | =item Not a perl script |
| 1464 | |
| 1465 | (F) The setuid emulator requires that scripts have a well-formed #! line |
| 1466 | even on machines that don't support the #! construct. The line must |
| 1467 | mention perl. |
| 1468 | |
| 1469 | =item Not a SCALAR reference |
| 1470 | |
| 1471 | (F) Perl was trying to evaluate a reference to a scalar value, but |
| 1472 | found a reference to something else instead. You can use the ref() |
| 1473 | function to find out what kind of ref it really was. See L<perlref>. |
| 1474 | |
| 1475 | =item Not a subroutine reference |
| 1476 | |
| 1477 | (F) Perl was trying to evaluate a reference to a code value (that is, a |
| 1478 | subroutine), but found a reference to something else instead. You can |
| 1479 | use the ref() function to find out what kind of ref it really was. |
| 1480 | See also L<perlref>. |
| 1481 | |
| 1482 | =item Not a subroutine reference in overload table |
| 1483 | |
| 1484 | (F) An attempt was made to specify an entry in an overloading table that |
| 1485 | doesn't somehow point to a valid subroutine. See L<overload>. |
| 1486 | |
| 1487 | =item Not an ARRAY reference |
| 1488 | |
| 1489 | (F) Perl was trying to evaluate a reference to an array value, but |
| 1490 | found a reference to something else instead. You can use the ref() |
| 1491 | function to find out what kind of ref it really was. See L<perlref>. |
| 1492 | |
| 1493 | =item Not enough arguments for %s |
| 1494 | |
| 1495 | (F) The function requires more arguments than you specified. |
| 1496 | |
| 1497 | =item Not enough format arguments |
| 1498 | |
| 1499 | (W) A format specified more picture fields than the next line supplied. |
| 1500 | See L<perlform>. |
| 1501 | |
| 1502 | =item Null filename used |
| 1503 | |
| 1504 | (F) You can't require the null filename, especially because on many machines |
| 1505 | that means the current directory! See L<perlfunc/require>. |
| 1506 | |
| 1507 | =item Null picture in formline |
| 1508 | |
| 1509 | (F) The first argument to formline must be a valid format picture |
| 1510 | specification. It was found to be empty, which probably means you |
| 1511 | supplied it an uninitialized value. See L<perlform>. |
| 1512 | |
| 1513 | =item NULL OP IN RUN |
| 1514 | |
| 1515 | (P) Some internal routine called run() with a null opcode pointer. |
| 1516 | |
| 1517 | =item Null realloc |
| 1518 | |
| 1519 | (P) An attempt was made to realloc NULL. |
| 1520 | |
| 1521 | =item NULL regexp argument |
| 1522 | |
| 1523 | (P) The internal pattern matching routines blew it big time. |
| 1524 | |
| 1525 | =item NULL regexp parameter |
| 1526 | |
| 1527 | (P) The internal pattern matching routines are out of their gourd. |
| 1528 | |
| 1529 | =item Odd number of elements in hash list |
| 1530 | |
| 1531 | (S) You specified an odd number of elements to a hash list, which is odd, |
| 1532 | because hash lists come in key/value pairs. |
| 1533 | |
| 1534 | =item Offset outside string |
| 1535 | |
| 1536 | (F) You tried to do a read/write/send/recv operation with an offset |
| 1537 | pointing outside the buffer. This is difficult to imagine. |
| 1538 | The sole exception to this is that C<sysread()>ing past the buffer |
| 1539 | will extend the buffer and zero pad the new area. |
| 1540 | |
| 1541 | =item oops: oopsAV |
| 1542 | |
| 1543 | (S) An internal warning that the grammar is screwed up. |
| 1544 | |
| 1545 | =item oops: oopsHV |
| 1546 | |
| 1547 | (S) An internal warning that the grammar is screwed up. |
| 1548 | |
| 1549 | =item Operation `%s': no method found,%s |
| 1550 | |
| 1551 | (F) An attempt was made to perform an overloaded operation for which |
| 1552 | no handler was defined. While some handlers can be autogenerated in |
| 1553 | terms of other handlers, there is no default handler for any |
| 1554 | operation, unless C<fallback> overloading key is specified to be |
| 1555 | true. See L<overload>. |
| 1556 | |
| 1557 | =item Operator or semicolon missing before %s |
| 1558 | |
| 1559 | (S) You used a variable or subroutine call where the parser was |
| 1560 | expecting an operator. The parser has assumed you really meant |
| 1561 | to use an operator, but this is highly likely to be incorrect. |
| 1562 | For example, if you say "*foo *foo" it will be interpreted as |
| 1563 | if you said "*foo * 'foo'". |
| 1564 | |
| 1565 | =item Out of memory for yacc stack |
| 1566 | |
| 1567 | (F) The yacc parser wanted to grow its stack so it could continue parsing, |
| 1568 | but realloc() wouldn't give it more memory, virtual or otherwise. |
| 1569 | |
| 1570 | =item Out of memory! |
| 1571 | |
| 1572 | (X|F) The malloc() function returned 0, indicating there was insufficient |
| 1573 | remaining memory (or virtual memory) to satisfy the request. |
| 1574 | |
| 1575 | The request was judged to be small, so the possibility to trap it |
| 1576 | depends on the way perl was compiled. By default it is not trappable. |
| 1577 | However, if compiled for this, Perl may use the contents of C<$^M> as |
| 1578 | an emergency pool after die()ing with this message. In this case the |
| 1579 | error is trappable I<once>. |
| 1580 | |
| 1581 | =item Out of memory during request for %s |
| 1582 | |
| 1583 | (F) The malloc() function returned 0, indicating there was insufficient |
| 1584 | remaining memory (or virtual memory) to satisfy the request. However, |
| 1585 | the request was judged large enough (compile-time default is 64K), so |
| 1586 | a possibility to shut down by trapping this error is granted. |
| 1587 | |
| 1588 | =item page overflow |
| 1589 | |
| 1590 | (W) A single call to write() produced more lines than can fit on a page. |
| 1591 | See L<perlform>. |
| 1592 | |
| 1593 | =item panic: ck_grep |
| 1594 | |
| 1595 | (P) Failed an internal consistency check trying to compile a grep. |
| 1596 | |
| 1597 | =item panic: ck_split |
| 1598 | |
| 1599 | (P) Failed an internal consistency check trying to compile a split. |
| 1600 | |
| 1601 | =item panic: corrupt saved stack index |
| 1602 | |
| 1603 | (P) The savestack was requested to restore more localized values than there |
| 1604 | are in the savestack. |
| 1605 | |
| 1606 | =item panic: die %s |
| 1607 | |
| 1608 | (P) We popped the context stack to an eval context, and then discovered |
| 1609 | it wasn't an eval context. |
| 1610 | |
| 1611 | =item panic: do_match |
| 1612 | |
| 1613 | (P) The internal pp_match() routine was called with invalid operational data. |
| 1614 | |
| 1615 | =item panic: do_split |
| 1616 | |
| 1617 | (P) Something terrible went wrong in setting up for the split. |
| 1618 | |
| 1619 | =item panic: do_subst |
| 1620 | |
| 1621 | (P) The internal pp_subst() routine was called with invalid operational data. |
| 1622 | |
| 1623 | =item panic: do_trans |
| 1624 | |
| 1625 | (P) The internal do_trans() routine was called with invalid operational data. |
| 1626 | |
| 1627 | =item panic: goto |
| 1628 | |
| 1629 | (P) We popped the context stack to a context with the specified label, |
| 1630 | and then discovered it wasn't a context we know how to do a goto in. |
| 1631 | |
| 1632 | =item panic: INTERPCASEMOD |
| 1633 | |
| 1634 | (P) The lexer got into a bad state at a case modifier. |
| 1635 | |
| 1636 | =item panic: INTERPCONCAT |
| 1637 | |
| 1638 | (P) The lexer got into a bad state parsing a string with brackets. |
| 1639 | |
| 1640 | =item panic: last |
| 1641 | |
| 1642 | (P) We popped the context stack to a block context, and then discovered |
| 1643 | it wasn't a block context. |
| 1644 | |
| 1645 | =item panic: leave_scope clearsv |
| 1646 | |
| 1647 | (P) A writable lexical variable became read-only somehow within the scope. |
| 1648 | |
| 1649 | =item panic: leave_scope inconsistency |
| 1650 | |
| 1651 | (P) The savestack probably got out of sync. At least, there was an |
| 1652 | invalid enum on the top of it. |
| 1653 | |
| 1654 | =item panic: malloc |
| 1655 | |
| 1656 | (P) Something requested a negative number of bytes of malloc. |
| 1657 | |
| 1658 | =item panic: mapstart |
| 1659 | |
| 1660 | (P) The compiler is screwed up with respect to the map() function. |
| 1661 | |
| 1662 | =item panic: null array |
| 1663 | |
| 1664 | (P) One of the internal array routines was passed a null AV pointer. |
| 1665 | |
| 1666 | =item panic: pad_alloc |
| 1667 | |
| 1668 | (P) The compiler got confused about which scratch pad it was allocating |
| 1669 | and freeing temporaries and lexicals from. |
| 1670 | |
| 1671 | =item panic: pad_free curpad |
| 1672 | |
| 1673 | (P) The compiler got confused about which scratch pad it was allocating |
| 1674 | and freeing temporaries and lexicals from. |
| 1675 | |
| 1676 | =item panic: pad_free po |
| 1677 | |
| 1678 | (P) An invalid scratch pad offset was detected internally. |
| 1679 | |
| 1680 | =item panic: pad_reset curpad |
| 1681 | |
| 1682 | (P) The compiler got confused about which scratch pad it was allocating |
| 1683 | and freeing temporaries and lexicals from. |
| 1684 | |
| 1685 | =item panic: pad_sv po |
| 1686 | |
| 1687 | (P) An invalid scratch pad offset was detected internally. |
| 1688 | |
| 1689 | =item panic: pad_swipe curpad |
| 1690 | |
| 1691 | (P) The compiler got confused about which scratch pad it was allocating |
| 1692 | and freeing temporaries and lexicals from. |
| 1693 | |
| 1694 | =item panic: pad_swipe po |
| 1695 | |
| 1696 | (P) An invalid scratch pad offset was detected internally. |
| 1697 | |
| 1698 | =item panic: pp_iter |
| 1699 | |
| 1700 | (P) The foreach iterator got called in a non-loop context frame. |
| 1701 | |
| 1702 | =item panic: realloc |
| 1703 | |
| 1704 | (P) Something requested a negative number of bytes of realloc. |
| 1705 | |
| 1706 | =item panic: restartop |
| 1707 | |
| 1708 | (P) Some internal routine requested a goto (or something like it), and |
| 1709 | didn't supply the destination. |
| 1710 | |
| 1711 | =item panic: return |
| 1712 | |
| 1713 | (P) We popped the context stack to a subroutine or eval context, and |
| 1714 | then discovered it wasn't a subroutine or eval context. |
| 1715 | |
| 1716 | =item panic: scan_num |
| 1717 | |
| 1718 | (P) scan_num() got called on something that wasn't a number. |
| 1719 | |
| 1720 | =item panic: sv_insert |
| 1721 | |
| 1722 | (P) The sv_insert() routine was told to remove more string than there |
| 1723 | was string. |
| 1724 | |
| 1725 | =item panic: top_env |
| 1726 | |
| 1727 | (P) The compiler attempted to do a goto, or something weird like that. |
| 1728 | |
| 1729 | =item panic: yylex |
| 1730 | |
| 1731 | (P) The lexer got into a bad state while processing a case modifier. |
| 1732 | |
| 1733 | =item Pareneses missing around "%s" list |
| 1734 | |
| 1735 | (W) You said something like |
| 1736 | |
| 1737 | my $foo, $bar = @_; |
| 1738 | |
| 1739 | when you meant |
| 1740 | |
| 1741 | my ($foo, $bar) = @_; |
| 1742 | |
| 1743 | Remember that "my" and "local" bind closer than comma. |
| 1744 | |
| 1745 | =item Perl %3.3f required--this is only version %s, stopped |
| 1746 | |
| 1747 | (F) The module in question uses features of a version of Perl more recent |
| 1748 | than the currently running version. How long has it been since you upgraded, |
| 1749 | anyway? See L<perlfunc/require>. |
| 1750 | |
| 1751 | =item Permission denied |
| 1752 | |
| 1753 | (F) The setuid emulator in suidperl decided you were up to no good. |
| 1754 | |
| 1755 | =item pid %d not a child |
| 1756 | |
| 1757 | (W) A warning peculiar to VMS. Waitpid() was asked to wait for a process which |
| 1758 | isn't a subprocess of the current process. While this is fine from VMS' |
| 1759 | perspective, it's probably not what you intended. |
| 1760 | |
| 1761 | =item POSIX getpgrp can't take an argument |
| 1762 | |
| 1763 | (F) Your C compiler uses POSIX getpgrp(), which takes no argument, unlike |
| 1764 | the BSD version, which takes a pid. |
| 1765 | |
| 1766 | =item Possible attempt to put comments in qw() list |
| 1767 | |
| 1768 | (W) qw() lists contain items separated by whitespace; as with literal |
| 1769 | strings, comment characters are not ignored, but are instead treated |
| 1770 | as literal data. (You may have used different delimiters than the |
| 1771 | exclamation marks parentheses shown here; braces are also frequently |
| 1772 | used.) |
| 1773 | |
| 1774 | You probably wrote something like this: |
| 1775 | |
| 1776 | @list = qw( |
| 1777 | a # a comment |
| 1778 | b # another comment |
| 1779 | ); |
| 1780 | |
| 1781 | when you should have written this: |
| 1782 | |
| 1783 | @list = qw( |
| 1784 | a |
| 1785 | b |
| 1786 | ); |
| 1787 | |
| 1788 | If you really want comments, build your list the |
| 1789 | old-fashioned way, with quotes and commas: |
| 1790 | |
| 1791 | @list = ( |
| 1792 | 'a', # a comment |
| 1793 | 'b', # another comment |
| 1794 | ); |
| 1795 | |
| 1796 | =item Possible attempt to separate words with commas |
| 1797 | |
| 1798 | (W) qw() lists contain items separated by whitespace; therefore commas |
| 1799 | aren't needed to separate the items. (You may have used different |
| 1800 | delimiters than the parentheses shown here; braces are also frequently |
| 1801 | used.) |
| 1802 | |
| 1803 | You probably wrote something like this: |
| 1804 | |
| 1805 | qw! a, b, c !; |
| 1806 | |
| 1807 | which puts literal commas into some of the list items. Write it without |
| 1808 | commas if you don't want them to appear in your data: |
| 1809 | |
| 1810 | qw! a b c !; |
| 1811 | |
| 1812 | =item Possible memory corruption: %s overflowed 3rd argument |
| 1813 | |
| 1814 | (F) An ioctl() or fcntl() returned more than Perl was bargaining for. |
| 1815 | Perl guesses a reasonable buffer size, but puts a sentinel byte at the |
| 1816 | end of the buffer just in case. This sentinel byte got clobbered, and |
| 1817 | Perl assumes that memory is now corrupted. See L<perlfunc/ioctl>. |
| 1818 | |
| 1819 | =item Precedence problem: open %s should be open(%s) |
| 1820 | |
| 1821 | (S) The old irregular construct |
| 1822 | |
| 1823 | open FOO || die; |
| 1824 | |
| 1825 | is now misinterpreted as |
| 1826 | |
| 1827 | open(FOO || die); |
| 1828 | |
| 1829 | because of the strict regularization of Perl 5's grammar into unary and |
| 1830 | list operators. (The old open was a little of both.) You must put |
| 1831 | parentheses around the filehandle, or use the new "or" operator instead of "||". |
| 1832 | |
| 1833 | =item print on closed filehandle %s |
| 1834 | |
| 1835 | (W) The filehandle you're printing on got itself closed sometime before now. |
| 1836 | Check your logic flow. |
| 1837 | |
| 1838 | =item printf on closed filehandle %s |
| 1839 | |
| 1840 | (W) The filehandle you're writing to got itself closed sometime before now. |
| 1841 | Check your logic flow. |
| 1842 | |
| 1843 | =item Probable precedence problem on %s |
| 1844 | |
| 1845 | (W) The compiler found a bare word where it expected a conditional, |
| 1846 | which often indicates that an || or && was parsed as part of the |
| 1847 | last argument of the previous construct, for example: |
| 1848 | |
| 1849 | open FOO || die; |
| 1850 | |
| 1851 | =item Prototype mismatch: (%s) vs (%s) |
| 1852 | |
| 1853 | (S) The subroutine being defined had a pre-declared (forward) declaration |
| 1854 | with a different function prototype. |
| 1855 | |
| 1856 | =item Read on closed filehandle E<lt>%sE<gt> |
| 1857 | |
| 1858 | (W) The filehandle you're reading from got itself closed sometime before now. |
| 1859 | Check your logic flow. |
| 1860 | |
| 1861 | =item Reallocation too large: %lx |
| 1862 | |
| 1863 | (F) You can't allocate more than 64K on an MSDOS machine. |
| 1864 | |
| 1865 | =item Recompile perl with B<-D>DEBUGGING to use B<-D> switch |
| 1866 | |
| 1867 | (F) You can't use the B<-D> option unless the code to produce the |
| 1868 | desired output is compiled into Perl, which entails some overhead, |
| 1869 | which is why it's currently left out of your copy. |
| 1870 | |
| 1871 | =item Recursive inheritance detected |
| 1872 | |
| 1873 | (F) More than 100 levels of inheritance were used. Probably indicates |
| 1874 | an unintended loop in your inheritance hierarchy. |
| 1875 | |
| 1876 | =item Reference miscount in sv_replace() |
| 1877 | |
| 1878 | (W) The internal sv_replace() function was handed a new SV with a |
| 1879 | reference count of other than 1. |
| 1880 | |
| 1881 | =item regexp memory corruption |
| 1882 | |
| 1883 | (P) The regular expression engine got confused by what the regular |
| 1884 | expression compiler gave it. |
| 1885 | |
| 1886 | =item regexp out of space |
| 1887 | |
| 1888 | (P) A "can't happen" error, because safemalloc() should have caught it earlier. |
| 1889 | |
| 1890 | =item regexp too big |
| 1891 | |
| 1892 | (F) The current implementation of regular expressions uses shorts as |
| 1893 | address offsets within a string. Unfortunately this means that if |
| 1894 | the regular expression compiles to longer than 32767, it'll blow up. |
| 1895 | Usually when you want a regular expression this big, there is a better |
| 1896 | way to do it with multiple statements. See L<perlre>. |
| 1897 | |
| 1898 | =item Reversed %s= operator |
| 1899 | |
| 1900 | (W) You wrote your assignment operator backwards. The = must always |
| 1901 | comes last, to avoid ambiguity with subsequent unary operators. |
| 1902 | |
| 1903 | =item Runaway format |
| 1904 | |
| 1905 | (F) Your format contained the ~~ repeat-until-blank sequence, but it |
| 1906 | produced 200 lines at once, and the 200th line looked exactly like the |
| 1907 | 199th line. Apparently you didn't arrange for the arguments to exhaust |
| 1908 | themselves, either by using ^ instead of @ (for scalar variables), or by |
| 1909 | shifting or popping (for array variables). See L<perlform>. |
| 1910 | |
| 1911 | =item Scalar value @%s[%s] better written as $%s[%s] |
| 1912 | |
| 1913 | (W) You've used an array slice (indicated by @) to select a single element of |
| 1914 | an array. Generally it's better to ask for a scalar value (indicated by $). |
| 1915 | The difference is that C<$foo[&bar]> always behaves like a scalar, both when |
| 1916 | assigning to it and when evaluating its argument, while C<@foo[&bar]> behaves |
| 1917 | like a list when you assign to it, and provides a list context to its |
| 1918 | subscript, which can do weird things if you're expecting only one subscript. |
| 1919 | |
| 1920 | On the other hand, if you were actually hoping to treat the array |
| 1921 | element as a list, you need to look into how references work, because |
| 1922 | Perl will not magically convert between scalars and lists for you. See |
| 1923 | L<perlref>. |
| 1924 | |
| 1925 | =item Scalar value @%s{%s} better written as $%s{%s} |
| 1926 | |
| 1927 | (W) You've used a hash slice (indicated by @) to select a single element of |
| 1928 | a hash. Generally it's better to ask for a scalar value (indicated by $). |
| 1929 | The difference is that C<$foo{&bar}> always behaves like a scalar, both when |
| 1930 | assigning to it and when evaluating its argument, while C<@foo{&bar}> behaves |
| 1931 | like a list when you assign to it, and provides a list context to its |
| 1932 | subscript, which can do weird things if you're expecting only one subscript. |
| 1933 | |
| 1934 | On the other hand, if you were actually hoping to treat the hash |
| 1935 | element as a list, you need to look into how references work, because |
| 1936 | Perl will not magically convert between scalars and lists for you. See |
| 1937 | L<perlref>. |
| 1938 | |
| 1939 | =item Script is not setuid/setgid in suidperl |
| 1940 | |
| 1941 | (F) Oddly, the suidperl program was invoked on a script with its setuid |
| 1942 | or setgid bit not set. This doesn't make much sense. |
| 1943 | |
| 1944 | =item Search pattern not terminated |
| 1945 | |
| 1946 | (F) The lexer couldn't find the final delimiter of a // or m{} |
| 1947 | construct. Remember that bracketing delimiters count nesting level. |
| 1948 | |
| 1949 | =item seek() on unopened file |
| 1950 | |
| 1951 | (W) You tried to use the seek() function on a filehandle that was either |
| 1952 | never opened or has been closed since. |
| 1953 | |
| 1954 | =item select not implemented |
| 1955 | |
| 1956 | (F) This machine doesn't implement the select() system call. |
| 1957 | |
| 1958 | =item sem%s not implemented |
| 1959 | |
| 1960 | (F) You don't have System V semaphore IPC on your system. |
| 1961 | |
| 1962 | =item semi-panic: attempt to dup freed string |
| 1963 | |
| 1964 | (S) The internal newSVsv() routine was called to duplicate a scalar |
| 1965 | that had previously been marked as free. |
| 1966 | |
| 1967 | =item Semicolon seems to be missing |
| 1968 | |
| 1969 | (W) A nearby syntax error was probably caused by a missing semicolon, |
| 1970 | or possibly some other missing operator, such as a comma. |
| 1971 | |
| 1972 | =item Send on closed socket |
| 1973 | |
| 1974 | (W) The filehandle you're sending to got itself closed sometime before now. |
| 1975 | Check your logic flow. |
| 1976 | |
| 1977 | =item Sequence (?#... not terminated |
| 1978 | |
| 1979 | (F) A regular expression comment must be terminated by a closing |
| 1980 | parenthesis. Embedded parentheses aren't allowed. See L<perlre>. |
| 1981 | |
| 1982 | =item Sequence (?%s...) not implemented |
| 1983 | |
| 1984 | (F) A proposed regular expression extension has the character reserved |
| 1985 | but has not yet been written. See L<perlre>. |
| 1986 | |
| 1987 | =item Sequence (?%s...) not recognized |
| 1988 | |
| 1989 | (F) You used a regular expression extension that doesn't make sense. |
| 1990 | See L<perlre>. |
| 1991 | |
| 1992 | =item Server error |
| 1993 | |
| 1994 | Also known as "500 Server error". |
| 1995 | |
| 1996 | B<This is a CGI error, not a Perl error>. |
| 1997 | |
| 1998 | You need to make sure your script is executable, is accessible by the user |
| 1999 | CGI is running the script under (which is probably not the user account you |
| 2000 | tested it under), does not rely on any environment variables (like PATH) |
| 2001 | from the user it isn't running under, and isn't in a location where the CGI |
| 2002 | server can't find it, basically, more or less. Please see the following |
| 2003 | for more information: |

| 2010 | |
| 2011 | =item setegid() not implemented |
| 2012 | |
| 2013 | (F) You tried to assign to C<$)>, and your operating system doesn't support |
| 2014 | the setegid() system call (or equivalent), or at least Configure didn't |
| 2015 | think so. |
| 2016 | |
| 2017 | =item seteuid() not implemented |
| 2018 | |
| 2019 | (F) You tried to assign to C<$E<gt>>, and your operating system doesn't support |
| 2020 | the seteuid() system call (or equivalent), or at least Configure didn't |
| 2021 | think so. |
| 2022 | |
| 2023 | =item setrgid() not implemented |
| 2024 | |
| 2025 | (F) You tried to assign to C<$(>, and your operating system doesn't support |
| 2026 | the setrgid() system call (or equivalent), or at least Configure didn't |
| 2027 | think so. |
| 2028 | |
| 2029 | =item setruid() not implemented |
| 2030 | |
| 2031 | (F) You tried to assign to C<$<lt>>, and your operating system doesn't support |
| 2032 | the setruid() system call (or equivalent), or at least Configure didn't |
| 2033 | think so. |
| 2034 | |
| 2035 | =item Setuid/gid script is writable by world |
| 2036 | |
| 2037 | (F) The setuid emulator won't run a script that is writable by the world, |
| 2038 | because the world might have written on it already. |
| 2039 | |
| 2040 | =item shm%s not implemented |
| 2041 | |
| 2042 | (F) You don't have System V shared memory IPC on your system. |
| 2043 | |
| 2044 | =item shutdown() on closed fd |
| 2045 | |
| 2046 | (W) You tried to do a shutdown on a closed socket. Seems a bit superfluous. |
| 2047 | |
| 2048 | =item SIG%s handler "%s" not defined |
| 2049 | |
| 2050 | (W) The signal handler named in %SIG doesn't, in fact, exist. Perhaps you |
| 2051 | put it into the wrong package? |
| 2052 | |
| 2053 | =item sort is now a reserved word |
| 2054 | |
| 2055 | (F) An ancient error message that almost nobody ever runs into anymore. |
| 2056 | But before sort was a keyword, people sometimes used it as a filehandle. |
| 2057 | |
| 2058 | =item Sort subroutine didn't return a numeric value |
| 2059 | |
| 2060 | (F) A sort comparison routine must return a number. You probably blew |
| 2061 | it by not using C<E<lt>=E<gt>> or C<cmp>, or by not using them correctly. |
| 2062 | See L<perlfunc/sort>. |
| 2063 | |
| 2064 | =item Sort subroutine didn't return single value |
| 2065 | |
| 2066 | (F) A sort comparison subroutine may not return a list value with more |
| 2067 | or less than one element. See L<perlfunc/sort>. |
| 2068 | |
| 2069 | =item Split loop |
| 2070 | |
| 2071 | (P) The split was looping infinitely. (Obviously, a split shouldn't iterate |
| 2072 | more times than there are characters of input, which is what happened.) |
| 2073 | See L<perlfunc/split>. |
| 2074 | |
| 2075 | =item Stat on unopened file E<lt>%sE<gt> |
| 2076 | |
| 2077 | (W) You tried to use the stat() function (or an equivalent file test) |
| 2078 | on a filehandle that was either never opened or has been closed since. |
| 2079 | |
| 2080 | =item Statement unlikely to be reached |
| 2081 | |
| 2082 | (W) You did an exec() with some statement after it other than a die(). |
| 2083 | This is almost always an error, because exec() never returns unless |
| 2084 | there was a failure. You probably wanted to use system() instead, |
| 2085 | which does return. To suppress this warning, put the exec() in a block |
| 2086 | by itself. |
| 2087 | |
| 2088 | =item Stub found while resolving method `%s' overloading `%s' in package `%s' |
| 2089 | |
| 2090 | (P) Overloading resolution over @ISA tree may be broken by importation stubs. |
| 2091 | Stubs should never be implicitely created, but explicit calls to C<can> |
| 2092 | may break this. |
| 2093 | |
| 2094 | =item Subroutine %s redefined |
| 2095 | |
| 2096 | (W) You redefined a subroutine. To suppress this warning, say |
| 2097 | |
| 2098 | { |
| 2099 | local $^W = 0; |
| 2100 | eval "sub name { ... }"; |
| 2101 | } |
| 2102 | |
| 2103 | =item Substitution loop |
| 2104 | |
| 2105 | (P) The substitution was looping infinitely. (Obviously, a |
| 2106 | substitution shouldn't iterate more times than there are characters of |
| 2107 | input, which is what happened.) See the discussion of substitution in |
| 2108 | L<perlop/"Quote and Quote-like Operators">. |
| 2109 | |
| 2110 | =item Substitution pattern not terminated |
| 2111 | |
| 2112 | (F) The lexer couldn't find the interior delimiter of a s/// or s{}{} |
| 2113 | construct. Remember that bracketing delimiters count nesting level. |
| 2114 | |
| 2115 | =item Substitution replacement not terminated |
| 2116 | |
| 2117 | (F) The lexer couldn't find the final delimiter of a s/// or s{}{} |
| 2118 | construct. Remember that bracketing delimiters count nesting level. |
| 2119 | |
| 2120 | =item substr outside of string |
| 2121 | |
| 2122 | (W) You tried to reference a substr() that pointed outside of a string. |
| 2123 | That is, the absolute value of the offset was larger than the length of |
| 2124 | the string. See L<perlfunc/substr>. |
| 2125 | |
| 2126 | =item suidperl is no longer needed since %s |
| 2127 | |
| 2128 | (F) Your Perl was compiled with B<-D>SETUID_SCRIPTS_ARE_SECURE_NOW, but a |
| 2129 | version of the setuid emulator somehow got run anyway. |
| 2130 | |
| 2131 | =item syntax error |
| 2132 | |
| 2133 | (F) Probably means you had a syntax error. Common reasons include: |
| 2134 | |
| 2135 | A keyword is misspelled. |
| 2136 | A semicolon is missing. |
| 2137 | A comma is missing. |
| 2138 | An opening or closing parenthesis is missing. |
| 2139 | An opening or closing brace is missing. |
| 2140 | A closing quote is missing. |
| 2141 | |
| 2142 | Often there will be another error message associated with the syntax |
| 2143 | error giving more information. (Sometimes it helps to turn on B<-w>.) |
| 2144 | The error message itself often tells you where it was in the line when |
| 2145 | it decided to give up. Sometimes the actual error is several tokens |
| 2146 | before this, because Perl is good at understanding random input. |
| 2147 | Occasionally the line number may be misleading, and once in a blue moon |
| 2148 | the only way to figure out what's triggering the error is to call |
| 2149 | C<perl -c> repeatedly, chopping away half the program each time to see |
| 2150 | if the error went away. Sort of the cybernetic version of S<20 questions>. |
| 2151 | |
| 2152 | =item syntax error at line %d: `%s' unexpected |
| 2153 | |
| 2154 | (A) You've accidentally run your script through the Bourne shell |
| 2155 | instead of Perl. Check the #! line, or manually feed your script |
| 2156 | into Perl yourself. |
| 2157 | |
| 2158 | =item System V IPC is not implemented on this machine |
| 2159 | |
| 2160 | (F) You tried to do something with a function beginning with "sem", "shm", |
| 2161 | or "msg". See L<perlfunc/semctl>, for example. |
| 2162 | |
| 2163 | =item Syswrite on closed filehandle |
| 2164 | |
| 2165 | (W) The filehandle you're writing to got itself closed sometime before now. |
| 2166 | Check your logic flow. |
| 2167 | |
| 2168 | =item tell() on unopened file |
| 2169 | |
| 2170 | (W) You tried to use the tell() function on a filehandle that was either |
| 2171 | never opened or has been closed since. |
| 2172 | |
| 2173 | =item Test on unopened file E<lt>%sE<gt> |
| 2174 | |
| 2175 | (W) You tried to invoke a file test operator on a filehandle that isn't |
| 2176 | open. Check your logic. See also L<perlfunc/-X>. |
| 2177 | |
| 2178 | =item That use of $[ is unsupported |
| 2179 | |
| 2180 | (F) Assignment to C<$[> is now strictly circumscribed, and interpreted as |
| 2181 | a compiler directive. You may say only one of |
| 2182 | |
| 2183 | $[ = 0; |
| 2184 | $[ = 1; |
| 2185 | ... |
| 2186 | local $[ = 0; |
| 2187 | local $[ = 1; |
| 2188 | ... |
| 2189 | |
| 2190 | This is to prevent the problem of one module changing the array base |
| 2191 | out from under another module inadvertently. See L<perlvar/$[>. |
| 2192 | |
| 2193 | =item The %s function is unimplemented |
| 2194 | |
| 2195 | The function indicated isn't implemented on this architecture, according |
| 2196 | to the probings of Configure. |
| 2197 | |
| 2198 | =item The crypt() function is unimplemented due to excessive paranoia |
| 2199 | |
| 2200 | (F) Configure couldn't find the crypt() function on your machine, |
| 2201 | probably because your vendor didn't supply it, probably because they |
| 2202 | think the U.S. Government thinks it's a secret, or at least that they |
| 2203 | will continue to pretend that it is. And if you quote me on that, I |
| 2204 | will deny it. |
| 2205 | |
| 2206 | =item The stat preceding C<-l _> wasn't an lstat |
| 2207 | |
| 2208 | (F) It makes no sense to test the current stat buffer for symbolic linkhood |
| 2209 | if the last stat that wrote to the stat buffer already went past |
| 2210 | the symlink to get to the real file. Use an actual filename instead. |
| 2211 | |
| 2212 | =item times not implemented |
| 2213 | |
| 2214 | (F) Your version of the C library apparently doesn't do times(). I suspect |
| 2215 | you're not running on Unix. |
| 2216 | |
| 2217 | =item Too few args to syscall |
| 2218 | |
| 2219 | (F) There has to be at least one argument to syscall() to specify the |
| 2220 | system call to call, silly dilly. |
| 2221 | |
| 2222 | =item Too late for "B<-T>" option |
| 2223 | |
| 2224 | (X) The #! line (or local equivalent) in a Perl script contains the |
| 2225 | B<-T> option, but Perl was not invoked with B<-T> in its argument |
| 2226 | list. This is an error because, by the time Perl discovers a B<-T> in |
| 2227 | a script, it's too late to properly taint everything from the |
| 2228 | environment. So Perl gives up. |
| 2229 | |
| 2230 | If the Perl script is being executed as a command using the #! |
| 2231 | mechanism (or its local equivalent), this error can usually be fixed |
| 2232 | by editing the #! line so that the B<-T> option is a part of Perl's |
| 2233 | first argument: e.g. change C<perl -n -T> to C<perl -T -n>. |
| 2234 | |
| 2235 | If the Perl script is being executed as C<perl scriptname>, then the |
| 2236 | B<-T> option must appear on the command line: C<perl -T scriptname>. |
| 2237 | |
| 2238 | =item Too many ('s |
| 2239 | |
| 2240 | =item Too many )'s |
| 2241 | |
| 2242 | (A) You've accidentally run your script through B<csh> instead |
| 2243 | of Perl. Check the #! line, or manually feed your script into |
| 2244 | Perl yourself. |
| 2245 | |
| 2246 | =item Too many args to syscall |
| 2247 | |
| 2248 | (F) Perl supports a maximum of only 14 args to syscall(). |
| 2249 | |
| 2250 | =item Too many arguments for %s |
| 2251 | |
| 2252 | (F) The function requires fewer arguments than you specified. |
| 2253 | |
| 2254 | =item trailing \ in regexp |
| 2255 | |
| 2256 | (F) The regular expression ends with an unbackslashed backslash. Backslash |
| 2257 | it. See L<perlre>. |
| 2258 | |
| 2259 | =item Translation pattern not terminated |
| 2260 | |
| 2261 | (F) The lexer couldn't find the interior delimiter of a tr/// or tr[][] |
| 2262 | construct. |
| 2263 | |
| 2264 | =item Translation replacement not terminated |
| 2265 | |
| 2266 | (F) The lexer couldn't find the final delimiter of a tr/// or tr[][] |
| 2267 | construct. |
| 2268 | |
| 2269 | =item truncate not implemented |
| 2270 | |
| 2271 | (F) Your machine doesn't implement a file truncation mechanism that |
| 2272 | Configure knows about. |
| 2273 | |
| 2274 | =item Type of arg %d to %s must be %s (not %s) |
| 2275 | |
| 2276 | (F) This function requires the argument in that position to be of a |
| 2277 | certain type. Arrays must be @NAME or C<@{EXPR}>. Hashes must be |
| 2278 | %NAME or C<%{EXPR}>. No implicit dereferencing is allowed--use the |
| 2279 | {EXPR} forms as an explicit dereference. See L<perlref>. |
| 2280 | |
| 2281 | =item umask: argument is missing initial 0 |
| 2282 | |
| 2283 | (W) A umask of 222 is incorrect. It should be 0222, because octal literals |
| 2284 | always start with 0 in Perl, as in C. |
| 2285 | |
| 2286 | =item Unable to create sub named "%s" |
| 2287 | |
| 2288 | (F) You attempted to create or access a subroutine with an illegal name. |
| 2289 | |
| 2290 | =item Unbalanced context: %d more PUSHes than POPs |
| 2291 | |
| 2292 | (W) The exit code detected an internal inconsistency in how many execution |
| 2293 | contexts were entered and left. |
| 2294 | |
| 2295 | =item Unbalanced saves: %d more saves than restores |
| 2296 | |
| 2297 | (W) The exit code detected an internal inconsistency in how many |
| 2298 | values were temporarily localized. |
| 2299 | |
| 2300 | =item Unbalanced scopes: %d more ENTERs than LEAVEs |
| 2301 | |
| 2302 | (W) The exit code detected an internal inconsistency in how many blocks |
| 2303 | were entered and left. |
| 2304 | |
| 2305 | =item Unbalanced tmps: %d more allocs than frees |
| 2306 | |
| 2307 | (W) The exit code detected an internal inconsistency in how many mortal |
| 2308 | scalars were allocated and freed. |
| 2309 | |
| 2310 | =item Undefined format "%s" called |
| 2311 | |
| 2312 | (F) The format indicated doesn't seem to exist. Perhaps it's really in |
| 2313 | another package? See L<perlform>. |
| 2314 | |
| 2315 | =item Undefined sort subroutine "%s" called |
| 2316 | |
| 2317 | (F) The sort comparison routine specified doesn't seem to exist. Perhaps |
| 2318 | it's in a different package? See L<perlfunc/sort>. |
| 2319 | |
| 2320 | =item Undefined subroutine &%s called |
| 2321 | |
| 2322 | (F) The subroutine indicated hasn't been defined, or if it was, it |
| 2323 | has since been undefined. |
| 2324 | |
| 2325 | =item Undefined subroutine called |
| 2326 | |
| 2327 | (F) The anonymous subroutine you're trying to call hasn't been defined, |
| 2328 | or if it was, it has since been undefined. |
| 2329 | |
| 2330 | =item Undefined subroutine in sort |
| 2331 | |
| 2332 | (F) The sort comparison routine specified is declared but doesn't seem to |
| 2333 | have been defined yet. See L<perlfunc/sort>. |
| 2334 | |
| 2335 | =item Undefined top format "%s" called |
| 2336 | |
| 2337 | (F) The format indicated doesn't seem to exist. Perhaps it's really in |
| 2338 | another package? See L<perlform>. |
| 2339 | |
| 2340 | =item unexec of %s into %s failed! |
| 2341 | |
| 2342 | (F) The unexec() routine failed for some reason. See your local FSF |
| 2343 | representative, who probably put it there in the first place. |
| 2344 | |
| 2345 | =item Unknown BYTEORDER |
| 2346 | |
| 2347 | (F) There are no byte-swapping functions for a machine with this byte order. |
| 2348 | |
| 2349 | =item unmatched () in regexp |
| 2350 | |
| 2351 | (F) Unbackslashed parentheses must always be balanced in regular |
| 2352 | expressions. If you're a vi user, the % key is valuable for finding |
| 2353 | the matching parenthesis. See L<perlre>. |
| 2354 | |
| 2355 | =item Unmatched right bracket |
| 2356 | |
| 2357 | (F) The lexer counted more closing curly brackets (braces) than opening |
| 2358 | ones, so you're probably missing an opening bracket. As a general |
| 2359 | rule, you'll find the missing one (so to speak) near the place you were |
| 2360 | last editing. |
| 2361 | |
| 2362 | =item unmatched [] in regexp |
| 2363 | |
| 2364 | (F) The brackets around a character class must match. If you wish to |
| 2365 | include a closing bracket in a character class, backslash it or put it first. |
| 2366 | See L<perlre>. |
| 2367 | |
| 2368 | =item Unquoted string "%s" may clash with future reserved word |
| 2369 | |
| 2370 | (W) You used a bare word that might someday be claimed as a reserved word. |
| 2371 | It's best to put such a word in quotes, or capitalize it somehow, or insert |
| 2372 | an underbar into it. You might also declare it as a subroutine. |
| 2373 | |
| 2374 | =item Unrecognized character \%03o ignored |
| 2375 | |
| 2376 | (S) A garbage character was found in the input, and ignored, in case it's |
| 2377 | a weird control character on an EBCDIC machine, or some such. |
| 2378 | |
| 2379 | =item Unrecognized signal name "%s" |
| 2380 | |
| 2381 | (F) You specified a signal name to the kill() function that was not recognized. |
| 2382 | Say C<kill -l> in your shell to see the valid signal names on your system. |
| 2383 | |
| 2384 | =item Unrecognized switch: -%s |
| 2385 | |
| 2386 | (F) You specified an illegal option to Perl. Don't do that. |
| 2387 | (If you think you didn't do that, check the #! line to see if it's |
| 2388 | supplying the bad switch on your behalf.) |
| 2389 | |
| 2390 | =item Unsuccessful %s on filename containing newline |
| 2391 | |
| 2392 | (W) A file operation was attempted on a filename, and that operation |
| 2393 | failed, PROBABLY because the filename contained a newline, PROBABLY |
| 2394 | because you forgot to chop() or chomp() it off. See L<perlfunc/chop>. |
| 2395 | |
| 2396 | =item Unsupported directory function "%s" called |
| 2397 | |
| 2398 | (F) Your machine doesn't support opendir() and readdir(). |
| 2399 | |
| 2400 | =item Unsupported function %s |
| 2401 | |
| 2402 | (F) This machines doesn't implement the indicated function, apparently. |
| 2403 | At least, Configure doesn't think so. |
| 2404 | |
| 2405 | =item Unsupported socket function "%s" called |
| 2406 | |
| 2407 | (F) Your machine doesn't support the Berkeley socket mechanism, or at |
| 2408 | least that's what Configure thought. |
| 2409 | |
| 2410 | =item Unterminated E<lt>E<gt> operator |
| 2411 | |
| 2412 | (F) The lexer saw a left angle bracket in a place where it was expecting |
| 2413 | a term, so it's looking for the corresponding right angle bracket, and not |
| 2414 | finding it. Chances are you left some needed parentheses out earlier in |
| 2415 | the line, and you really meant a "less than". |
| 2416 | |
| 2417 | =item Use of $# is deprecated |
| 2418 | |
| 2419 | (D) This was an ill-advised attempt to emulate a poorly defined B<awk> feature. |
| 2420 | Use an explicit printf() or sprintf() instead. |
| 2421 | |
| 2422 | =item Use of $* is deprecated |
| 2423 | |
| 2424 | (D) This variable magically turned on multi-line pattern matching, both for |
| 2425 | you and for any luckless subroutine that you happen to call. You should |
| 2426 | use the new C<//m> and C<//s> modifiers now to do that without the dangerous |
| 2427 | action-at-a-distance effects of C<$*>. |
| 2428 | |
| 2429 | =item Use of %s in printf format not supported |
| 2430 | |
| 2431 | (F) You attempted to use a feature of printf that is accessible from |
| 2432 | only C. This usually means there's a better way to do it in Perl. |
| 2433 | |
| 2434 | =item Use of %s is deprecated |
| 2435 | |
| 2436 | (D) The construct indicated is no longer recommended for use, generally |
| 2437 | because there's a better way to do it, and also because the old way has |
| 2438 | bad side effects. |
| 2439 | |
| 2440 | =item Use of bare E<lt>E<lt> to mean E<lt>E<lt>"" is deprecated |
| 2441 | |
| 2442 | (D) You are now encouraged to use the explicitly quoted form if you |
| 2443 | wish to use a blank line as the terminator of the here-document. |
| 2444 | |
| 2445 | =item Use of implicit split to @_ is deprecated |
| 2446 | |
| 2447 | (D) It makes a lot of work for the compiler when you clobber a |
| 2448 | subroutine's argument list, so it's better if you assign the results of |
| 2449 | a split() explicitly to an array (or list). |
| 2450 | |
| 2451 | =item Use of uninitialized value |
| 2452 | |
| 2453 | (W) An undefined value was used as if it were already defined. It was |
| 2454 | interpreted as a "" or a 0, but maybe it was a mistake. To suppress this |
| 2455 | warning assign an initial value to your variables. |
| 2456 | |
| 2457 | =item Useless use of %s in void context |
| 2458 | |
| 2459 | (W) You did something without a side effect in a context that does nothing |
| 2460 | with the return value, such as a statement that doesn't return a value |
| 2461 | from a block, or the left side of a scalar comma operator. Very often |
| 2462 | this points not to stupidity on your part, but a failure of Perl to parse |
| 2463 | your program the way you thought it would. For example, you'd get this |
| 2464 | if you mixed up your C precedence with Python precedence and said |
| 2465 | |
| 2466 | $one, $two = 1, 2; |
| 2467 | |
| 2468 | when you meant to say |
| 2469 | |
| 2470 | ($one, $two) = (1, 2); |
| 2471 | |
| 2472 | Another common error is to use ordinary parentheses to construct a list |
| 2473 | reference when you should be using square or curly brackets, for |
| 2474 | example, if you say |
| 2475 | |
| 2476 | $array = (1,2); |
| 2477 | |
| 2478 | when you should have said |
| 2479 | |
| 2480 | $array = [1,2]; |
| 2481 | |
| 2482 | The square brackets explicitly turn a list value into a scalar value, |
| 2483 | while parentheses do not. So when a parenthesized list is evaluated in |
| 2484 | a scalar context, the comma is treated like C's comma operator, which |
| 2485 | throws away the left argument, which is not what you want. See |
| 2486 | L<perlref> for more on this. |
| 2487 | |
| 2488 | =item untie attempted while %d inner references still exist |
| 2489 | |
| 2490 | (W) A copy of the object returned from C<tie> (or C<tied>) was still |
| 2491 | valid when C<untie> was called. |
| 2492 | |
| 2493 | =item Value of %s construct can be "0"; test with defined() |
| 2494 | |
| 2495 | (W) In a conditional expression, you used <HANDLE>, <*> (glob), or |
| 2496 | C<readdir> as a boolean value. Each of these constructs can return a |
| 2497 | value of "0"; that would make the conditional expression false, which |
| 2498 | is probably not what you intended. When using these constructs in |
| 2499 | conditional expressions, test their values with the C<defined> operator. |
| 2500 | |
| 2501 | =item Variable "%s" is not imported%s |
| 2502 | |
| 2503 | (F) While "use strict" in effect, you referred to a global variable |
| 2504 | that you apparently thought was imported from another module, because |
| 2505 | something else of the same name (usually a subroutine) is exported |
| 2506 | by that module. It usually means you put the wrong funny character |
| 2507 | on the front of your variable. |
| 2508 | |
| 2509 | =item Variable "%s" may be unavailable |
| 2510 | |
| 2511 | (W) An inner (nested) I<anonymous> subroutine is inside a I<named> |
| 2512 | subroutine, and outside that is another subroutine; and the anonymous |
| 2513 | (innermost) subroutine is referencing a lexical variable defined in |
| 2514 | the outermost subroutine. For example: |
| 2515 | |
| 2516 | sub outermost { my $a; sub middle { sub { $a } } } |
| 2517 | |
| 2518 | If the anonymous subroutine is called or referenced (directly or |
| 2519 | indirectly) from the outermost subroutine, it will share the variable |
| 2520 | as you would expect. But if the anonymous subroutine is called or |
| 2521 | referenced when the outermost subroutine is not active, it will see |
| 2522 | the value of the shared variable as it was before and during the |
| 2523 | *first* call to the outermost subroutine, which is probably not what |
| 2524 | you want. |
| 2525 | |
| 2526 | In these circumstances, it is usually best to make the middle |
| 2527 | subroutine anonymous, using the C<sub {}> syntax. Perl has specific |
| 2528 | support for shared variables in nested anonymous subroutines; a named |
| 2529 | subroutine in between interferes with this feature. |
| 2530 | |
| 2531 | =item Variable "%s" will not stay shared |
| 2532 | |
| 2533 | (W) An inner (nested) I<named> subroutine is referencing a lexical |
| 2534 | variable defined in an outer subroutine. |
| 2535 | |
| 2536 | When the inner subroutine is called, it will probably see the value of |
| 2537 | the outer subroutine's variable as it was before and during the |
| 2538 | *first* call to the outer subroutine; in this case, after the first |
| 2539 | call to the outer subroutine is complete, the inner and outer |
| 2540 | subroutines will no longer share a common value for the variable. In |
| 2541 | other words, the variable will no longer be shared. |
| 2542 | |
| 2543 | Furthermore, if the outer subroutine is anonymous and references a |
| 2544 | lexical variable outside itself, then the outer and inner subroutines |
| 2545 | will I<never> share the given variable. |
| 2546 | |
| 2547 | This problem can usually be solved by making the inner subroutine |
| 2548 | anonymous, using the C<sub {}> syntax. When inner anonymous subs that |
| 2549 | reference variables in outer subroutines are called or referenced, |
| 2550 | they are automatically re-bound to the current values of such |
| 2551 | variables. |
| 2552 | |
| 2553 | =item Variable syntax |
| 2554 | |
| 2555 | (A) You've accidentally run your script through B<csh> instead |
| 2556 | of Perl. Check the #! line, or manually feed your script into |
| 2557 | Perl yourself. |
| 2558 | |
| 2559 | =item Warning: something's wrong |
| 2560 | |
| 2561 | (W) You passed warn() an empty string (the equivalent of C<warn "">) or |
| 2562 | you called it with no args and C<$_> was empty. |
| 2563 | |
| 2564 | =item Warning: unable to close filehandle %s properly |
| 2565 | |
| 2566 | (S) The implicit close() done by an open() got an error indication on the |
| 2567 | close(). This usually indicates your file system ran out of disk space. |
| 2568 | |
| 2569 | =item Warning: Use of "%s" without parentheses is ambiguous |
| 2570 | |
| 2571 | (S) You wrote a unary operator followed by something that looks like a |
| 2572 | binary operator that could also have been interpreted as a term or |
| 2573 | unary operator. For instance, if you know that the rand function |
| 2574 | has a default argument of 1.0, and you write |
| 2575 | |
| 2576 | rand + 5; |
| 2577 | |
| 2578 | you may THINK you wrote the same thing as |
| 2579 | |
| 2580 | rand() + 5; |
| 2581 | |
| 2582 | but in actual fact, you got |
| 2583 | |
| 2584 | rand(+5); |
| 2585 | |
| 2586 | So put in parentheses to say what you really mean. |
| 2587 | |
| 2588 | =item Write on closed filehandle |
| 2589 | |
| 2590 | (W) The filehandle you're writing to got itself closed sometime before now. |
| 2591 | Check your logic flow. |
| 2592 | |
| 2593 | =item X outside of string |
| 2594 | |
| 2595 | (F) You had a pack template that specified a relative position before |
| 2596 | the beginning of the string being unpacked. See L<perlfunc/pack>. |
| 2597 | |
| 2598 | =item x outside of string |
| 2599 | |
| 2600 | (F) You had a pack template that specified a relative position after |
| 2601 | the end of the string being unpacked. See L<perlfunc/pack>. |
| 2602 | |
| 2603 | =item Xsub "%s" called in sort |
| 2604 | |
| 2605 | (F) The use of an external subroutine as a sort comparison is not yet supported. |
| 2606 | |
| 2607 | =item Xsub called in sort |
| 2608 | |
| 2609 | (F) The use of an external subroutine as a sort comparison is not yet supported. |
| 2610 | |
| 2611 | =item You can't use C<-l> on a filehandle |
| 2612 | |
| 2613 | (F) A filehandle represents an opened file, and when you opened the file it |
| 2614 | already went past any symlink you are presumably trying to look for. |
| 2615 | Use a filename instead. |
| 2616 | |
| 2617 | =item YOU HAVEN'T DISABLED SET-ID SCRIPTS IN THE KERNEL YET! |
| 2618 | |
| 2619 | (F) And you probably never will, because you probably don't have the |
| 2620 | sources to your kernel, and your vendor probably doesn't give a rip |
| 2621 | about what you want. Your best bet is to use the wrapsuid script in |
| 2622 | the eg directory to put a setuid C wrapper around your script. |
| 2623 | |
| 2624 | =item You need to quote "%s" |
| 2625 | |
| 2626 | (W) You assigned a bareword as a signal handler name. Unfortunately, you |
| 2627 | already have a subroutine of that name declared, which means that Perl 5 |
| 2628 | will try to call the subroutine when the assignment is executed, which is |
| 2629 | probably not what you want. (If it IS what you want, put an & in front.) |
| 2630 | |
| 2631 | =item [gs]etsockopt() on closed fd |
| 2632 | |
| 2633 | (W) You tried to get or set a socket option on a closed socket. |
| 2634 | Did you forget to check the return value of your socket() call? |
| 2635 | See L<perlfunc/getsockopt>. |
| 2636 | |
| 2637 | =item \1 better written as $1 |
| 2638 | |
| 2639 | (W) Outside of patterns, backreferences live on as variables. The use |
| 2640 | of backslashes is grandfathered on the right-hand side of a |
| 2641 | substitution, but stylistically it's better to use the variable form |
| 2642 | because other Perl programmers will expect it, and it works better |
| 2643 | if there are more than 9 backreferences. |
| 2644 | |
| 2645 | =item '|' and 'E<lt>' may not both be specified on command line |
| 2646 | |
| 2647 | (F) An error peculiar to VMS. Perl does its own command line redirection, and |
| 2648 | found that STDIN was a pipe, and that you also tried to redirect STDIN using |
| 2649 | 'E<lt>'. Only one STDIN stream to a customer, please. |
| 2650 | |
| 2651 | =item '|' and 'E<gt>' may not both be specified on command line |
| 2652 | |
| 2653 | (F) An error peculiar to VMS. Perl does its own command line redirection, and |
| 2654 | thinks you tried to redirect stdout both to a file and into a pipe to another |
| 2655 | command. You need to choose one or the other, though nothing's stopping you |
| 2656 | from piping into a program or Perl script which 'splits' output into two |
| 2657 | streams, such as |
| 2658 | |
| 2659 | open(OUT,">$ARGV[0]") or die "Can't write to $ARGV[0]: $!"; |
| 2660 | while (<STDIN>) { |
| 2661 | print; |
| 2662 | print OUT; |
| 2663 | } |
| 2664 | close OUT; |
| 2665 | |
| 2666 | =item Got an error from DosAllocMem |
| 2667 | |
| 2668 | (P) An error peculiar to OS/2. Most probably you're using an obsolete |
| 2669 | version of Perl, and this should not happen anyway. |
| 2670 | |
| 2671 | =item Malformed PERLLIB_PREFIX |
| 2672 | |
| 2673 | (F) An error peculiar to OS/2. PERLLIB_PREFIX should be of the form |
| 2674 | |
| 2675 | prefix1;prefix2 |
| 2676 | |
| 2677 | or |
| 2678 | |
| 2679 | prefix1 prefix2 |
| 2680 | |
| 2681 | with non-empty prefix1 and prefix2. If C<prefix1> is indeed a prefix of |
| 2682 | a builtin library search path, prefix2 is substituted. The error may appear |
| 2683 | if components are not found, or are too long. See L<perlos2/"PERLLIB_PREFIX">. |
| 2684 | |
| 2685 | =item PERL_SH_DIR too long |
| 2686 | |
| 2687 | (F) An error peculiar to OS/2. PERL_SH_DIR is the directory to find the |
| 2688 | C<sh>-shell in. See L<perlos2/"PERL_SH_DIR">. |
| 2689 | |
| 2690 | =item Process terminated by SIG%s |
| 2691 | |
| 2692 | (W) This is a standard message issued by OS/2 applications, while *nix |
| 2693 | applications die in silence. It is considered a feature of the OS/2 |
| 2694 | port. One can easily disable this by appropriate sighandlers, see |
| 2695 | L<perlipc/"Signals">. See L<perlos2/"Process terminated by SIGTERM/SIGINT">. |
| 2696 | |
