| 1 | after 5.003_05: |
| 2 | PERLLIB_PREFIX was not active if it matches an element of @INC |
| 3 | as a whole. |
| 4 | Do not need PERL_SBRK if crtdll-revision is >= 50. |
| 5 | Use -Zsmall-conv if crtdll-revision is >= 50 (in static perl!). |
| 6 | :7: warning: #warning <dirent.h> requires <sys/types.h> |
| 7 | We compile miniperl static. It cannot fork, thus there may be |
| 8 | problems with pipes (since HAS_FORK is in |
| 9 | place). Pipes are required by makemaker. |
| 10 | We compile perl___.exe A.OUT and dynamic. It should be able to |
| 11 | fork. |
| 12 | If we can fork, we my_popen by popen unless "-|". Thus we |
| 13 | write a cooky "-1" into the pid array to indicate |
| 14 | this. |
| 15 | Apparently we can fork, and we can load dynamic extensions |
| 16 | now, though probably not simultaneously. |
| 17 | *DB tests corrected for OS/2 one-user stat[2]. |
| 18 | /bin/sh is intercepted and replaced by SH_PATH. |
| 19 | Note that having '\\' in the command line of one-arg `system' |
| 20 | would trigger call via shell. |
| 21 | Segfault with system {'ls'} 'blah'; corrected. |
| 22 | Documentation of OS/2-different features added to main PODs. |
| 23 | New buitins in Cwd:: |
| 24 | |
| 25 | Cwd::current_drive |
| 26 | Cwd::sys_chdir - leaves drive as it is. |
| 27 | Cwd::change_drive |
| 28 | Cwd::sys_is_absolute - has drive letter and is_rooted |
| 29 | Cwd::sys_is_rooted - has leading [/\\] (maybe |
| 30 | after a drive) |
| 31 | Cwd::sys_is_relative - changes with current dir |
| 32 | Cwd::sys_cwd - Interface to cwd from EMX. |
| 33 | Cwd::sys_abspath(name, dir) |
| 34 | - Really really odious |
| 35 | function. Returns absolute |
| 36 | name of file which would |
| 37 | have 'name' if CWD were 'dir'. |
| 38 | Dir defaults to the current dir. |
| 39 | Cwd::extLibpath [type] - Get/set current value of extended |
| 40 | Cwd::extLibpath_set - library search path. |
| 41 | path [type] |
| 42 | The optional last argument redirects |
| 43 | to END-path if true, |
| 44 | default is to search BEGIN-path. |
| 45 | (Note that some of these may be moved to different |
| 46 | libraries - eventually). |
| 47 | Executables: |
| 48 | perl - can fork, can dynalink (but not simultaneously) |
| 49 | perl_ - can fork, cannot dynalink |
| 50 | perl__ - same as perl___, but PM. |
| 51 | perl___ - cannot fork, can dynalink. |
| 52 | The build of the first one - perl - is rather convoluted, and |
| 53 | requires a build of miniperl_. |
| 54 | |
| 55 | after 5.003_07: |
| 56 | custom tmpfile and tmpname which may use $TMP, $TEMP. |
| 57 | all the calls to OS/2 API wrapped so that it is safe to use |
| 58 | them under DOS (may die(), though). |
| 59 | Tested that popen works under DOS with modified PDKSH and RSX. |
| 60 | File::Copy works under DOS. |
| 61 | MakeMaker modified to work under DOS (perlmain.c.tmp and sh -c true). |
| 62 | |
| 63 | after 5.003_08: |
| 64 | OS2::PrfDB exports symbols as documented; |
| 65 | should work on OS/2 2.1 again. |
| 66 | uses reliable signals when spawing. |
| 67 | do not use popen() any more - no intermediate shell unless needed. |
| 68 | |
| 69 | after 5.003_11: |
| 70 | Functions emx_{malloc,realloc,calloc,free} are exported from DLL. |
| 71 | get_sysinfo() bugs corrected (flags were not used and wrongly defined). |
| 72 | |
| 73 | after 5.003_20: |
| 74 | _isterm is substituted instead of isatty, s?random instead of srand. |
| 75 | `register' disabled if -DDEBUGGING and not AOUT build: stupid SD386. |
| 76 | 3-argument select() was stomping over memory. |
| 77 | |
| 78 | after 5.003_21: |
| 79 | Can start scripts by executing 'dir/script' and |
| 80 | 'script.sh'. Form without extension will call shell only if |
| 81 | the specified file exists (will not look on path) (to prohibit |
| 82 | trying to run shell commands directly). - Needed by magic.t. |
| 83 | |
| 84 | after 5.003_27: |
| 85 | ALTERNATE_SHEBANG="extproc " supported, thus options on this |
| 86 | line are processed (possibly twice). -S is made legal on such |
| 87 | a line. This -S -x is not needed any more. |
| 88 | perl.dll may be used from non-EMX programs (via PERL_SYS_INIT |
| 89 | - the caller should have valid variable "env" with |
| 90 | environment). Known problems: $$ does not work - is 0, waitpid |
| 91 | returns immediately, thus Perl cannot wait for completion of |
| 92 | started programs. |
| 93 | |
| 94 | after 5.004_01: |
| 95 | flock emulation added (disable by setting env PERL_USE_FLOCK=0), |
| 96 | thanks to Rocco Caputo; |
| 97 | RSX bug with missing waitpid circomvented; |
| 98 | -S bug with full path with \ corrected. |
| 99 | |
| 100 | before 5.004_02: |
| 101 | -S switch to perl enables a search with additional extensions |
| 102 | .cmd, .btm, .bat, .pl as well. This means that if you have |
| 103 | mycmd.pl or mycmd.bat on PATH, |
| 104 | perl -S mycmd |
| 105 | will work. Perl will also look in the current directory first. |
| 106 | Moreover, a bug with \; in PATH being non-separator is fixed. |
| 107 | |
| 108 | after 5.004_03: |
| 109 | $^E tracks calls to CRT now. (May break if Perl masks some |
| 110 | changes to errno?) |
| 111 | $0 may be edited to longer lengths (at least under OS/2). |
| 112 | OS2::REXX->loads looks in the OS/2-ish fashion too. |
| 113 | |
| 114 | after 5.004_04: |
| 115 | Default perl.exe was built with a shorter stack than expected. |
| 116 | Strip extensions DLLs too (unless debugging build). |
| 117 | ./os2.c being RO could stop cp. |
| 118 | When starting scripts, Perl will find them on path (using the same |
| 119 | extensions as for -S command-line switch). If it finds magic |
| 120 | `extproc ' or `#!' cookies, it will start the scripts directly. |
| 121 | May use `cmd /c more <' as a pager. |
| 122 | If a program could not be started, this might have been hidden. |
| 123 | End of pipe was closed twice when `open'ing a pipeline. |
| 124 | |
| 125 | after 5.004_53: |
| 126 | Minimal thread support added. One needs to manually move pthread.h |
| 127 | |
| 128 | after 5.004_64: |
| 129 | Make DLL names different if thread-enabled. |
| 130 | Emit more informative internal DLL descriptions. |
| 131 | |
| 132 | 5.004_72: |
| 133 | Updated OS2::Process (v0.2) included. |
| 134 | |
| 135 | after 5.004_73: |
| 136 | Fixed a bug with argv not NULL-terminated when starting scripts. |
| 137 | Support all the forms of starting scripts. |
| 138 | Support killing a child when receiving a signal during system() |
| 139 | (in two stage, on first send the same signal, on the next |
| 140 | send SIGKILL). |
| 141 | Add the same logic for scripts as in pdksh, including |
| 142 | stripping the path from #! line if needed, |
| 143 | calling EXECSHELL or COMSPEC for magic-less scripts; |
| 144 | Now pdksh is called only if one-arg system()/friends contains |
| 145 | metachars, or if magic-line asks for sh, or there is no magic |
| 146 | line and EXECSHELL is set to sh. |
| 147 | Shell is supplied the original command line if possible. |
| 148 | |
| 149 | after 5.005_02: |
| 150 | Can start PM programs from non-PM sessions by plain system() |
| 151 | and friends. Can start DOS/Win programs. Can start |
| 152 | fullscreen programs from non-fullscreen sessions too. |
| 153 | In fact system(P_PM,...) was broken. |
| 154 | We mangle the name of perl*.DLL, to allow coexistence of different |
| 155 | versions of Perl executables on the system. Mangling of |
| 156 | names of extension DLL is also changed, thus running two |
| 157 | different versions of the executable with loaded |
| 158 | extensions should not lead to conflicts (since |
| 159 | extension-full-name and Perl-version mangling work in the |
| 160 | same set ot 576 possible keys, this may lead to clashes). |
| 161 | $^E was reset on the second read, and contained ".\r\n" at the end. |
| 162 | |
| 163 | after 5.005_53: |
| 164 | Would segfault system()ing non-existing program; |
| 165 | AOUT build was hosed; |
| 166 | warning-test for getpriority() might lock the system hard on |
| 167 | pre-fixpak22 configuration (calling getpriority() on |
| 168 | non-existing process triggers a system-wide bug). |
| 169 | |
| 170 | |
| 171 | PrfDB was using a bug in processing XSUBs returning U32. |
| 172 | |
| 173 | Variable $OS2::emx_rev implemented (string and numberic values |
| 174 | are the same as C variables _emx_rev and _emx_vprt). |
| 175 | Variable $OS2::emx_env implemented (same as C variable _emx_env). |
| 176 | Variable $OS2::os_ver implemented (_osmajor + 0.001 * _osminor). |
| 177 | |
| 178 | Improved centralized management of HAB and HMQ. To get Perl's |
| 179 | HAB, call perl_hab_GET(). (After the initial call one |
| 180 | can use Perl_hab instead.) To require Perl's HMQ, |
| 181 | call perl_hmq_GET(), to release it call perl_hmq_UNSET(), |
| 182 | to obtain it between these calls use Perl_hmq. |
| 183 | HMQ management is refcounted, and the program will morph |
| 184 | itself into/from PM if required. |
| 185 | If perl.h cannot be included, hab may be obtained by Perl_hab_GET(). |
| 186 | |
| 187 | New function OS2::Error(do_harderror,do_exception). Returns |
| 188 | undef if it was not called yet, otherwise bit 1 is |
| 189 | set if on previous call do_harderror was enabled, bit |
| 190 | 2 is set if if on previous call do_exception was enabled. |
| 191 | This function enables/disables error popups associated with |
| 192 | hardware errors (Disk not ready etc.) and software exceptions. |
| 193 | |
| 194 | New function OS2::Errors2Drive(drive). Returns undef if it was |
| 195 | not called yet, otherwise return false if Errors were |
| 196 | not requested to be written to a hard drive, or the |
| 197 | drive letter if this was requested. |
| 198 | This function may redirect error popups associated with |
| 199 | hardware errors (Disk not ready etc.) and software exceptions |
| 200 | to the file POPUPLOG.OS2 at the root directory of the |
| 201 | specified drive. Overrides OS2::Error() specified by |
| 202 | individual programs. Given argument undef will |
| 203 | disable redirection. Has global effect, persists |
| 204 | after the application exits. |
| 205 | |
| 206 | New function OS2::SysInfo(). Returns a hash with system information. |
| 207 | The keys of the hash are |
| 208 | |
| 209 | MAX_PATH_LENGTH, MAX_TEXT_SESSIONS, MAX_PM_SESSIONS, |
| 210 | MAX_VDM_SESSIONS, BOOT_DRIVE, DYN_PRI_VARIATION, |
| 211 | MAX_WAIT, MIN_SLICE, MAX_SLICE, PAGE_SIZE, |
| 212 | VERSION_MAJOR, VERSION_MINOR, VERSION_REVISION, |
| 213 | MS_COUNT, TIME_LOW, TIME_HIGH, TOTPHYSMEM, TOTRESMEM, |
| 214 | TOTAVAILMEM, MAXPRMEM, MAXSHMEM, TIMER_INTERVAL, |
| 215 | MAX_COMP_LENGTH, FOREGROUND_FS_SESSION, |
| 216 | FOREGROUND_PROCESS |
| 217 | |
| 218 | New function OS2::BootDrive(force). Returns a letter without colon. |
| 219 | |
| 220 | New functions OS2::MorphPM(serve)/OS2::UnMorphPM(serve). Transforms |
| 221 | the current application into a PM application and back. |
| 222 | The argument true means that a real message loop is |
| 223 | going to be performed. |
| 224 | OS2::MorphPM() returns the PM message queue handle as an integer. |
| 225 | |
| 226 | New function OS2::Serve_Messages(force). Fake on-demand |
| 227 | retrieval of outstanding PM messages. If force is false, |
| 228 | will not dispatch messages if a real message loop is known to |
| 229 | be present. Returns number of messages retrieved. |
| 230 | Dies with "QUITing..." if WM_QUIT message is obtained. |
| 231 | |
| 232 | New function OS2::Process_Messages(force [, cnt]). Retrieval |
| 233 | of PM messages until window creation/destruction. |
| 234 | If force is false, will not dispatch messages |
| 235 | if a real message loop is known to be present. |
| 236 | Returns change in number of windows. If cnt is given, |
| 237 | it is incremented by the number of messages retrieved. |
| 238 | Dies with "QUITing..." if WM_QUIT message is obtained. |
| 239 | |
| 240 | after 5.005_54: |
| 241 | Opening pipes from/to processes could fail if (un)appropriate |
| 242 | combination of STDIN/STDOUT was closed. |
| 243 | |
| 244 | If the only shell-metachars of a command are ' 2>&1' at the |
| 245 | end of a command, it is executed without calling the external shell. |
| 246 | |
| 247 | after 5.005_57: |
| 248 | Make UDP sockets return correct caller address (OS2 API bug); |
| 249 | Enable TCPIPV4 defines (works with Warp 3 IAK too?!); |
| 250 | Force Unix-domain sockets to start with "/socket", convert |
| 251 | '/' to '\' in the calls; |
| 252 | Make C<system 1, $cmd> to treat $cmd as in C<system $cmd>; |
| 253 | Autopatch Configure; |
| 254 | Find name and location of g[nu]patch.exe; |
| 255 | Autocopy perl????.dll to t/ when testing; |
| 256 | |
| 257 | after 5.005_62: |
| 258 | Extract a lightweight DLL access module OS2::DLL from OS2::REXX |
| 259 | which would not load REXX runtime system; |
| 260 | Allow compile with os2.h which loads os2tk.h instead of os2emx.h; |
| 261 | Put the version of EMX CRTL into -D define; |
| 262 | Use _setsyserror() to store last error of OS/2 API for $^E; |
| 263 | New macro PERL_SYS_INIT3(argvp, argcp, envp); |
| 264 | Make Dynaloader return info on the failing module after failed dl_open(); |
| 265 | OS2::REXX test were done for interactive testing (were writing |
| 266 | "ok" to stderr); |
| 267 | system() and friends return -1 on failure (was 0xFF00); |
| 268 | Put the full name of executable into $^X |
| 269 | (alas, uppercased - but with /); |
| 270 | t/io/fs.t was failing on HPFS386; |
| 271 | Remove extra ';' from defines for MQ operations. |
| 272 | |
| 273 | pre 5.6.1: |
| 274 | Resolved: "Bad free()" messages (e.g., from DB_File) with -Zomf build. |
| 275 | The reason was: when an extension DLL was linked, the order of |
| 276 | libraries was similar to this: |
| 277 | f1.obj f2.obj libperl.lib -llibr1 -llibr2 |
| 278 | (with C RTL implicitly after this). When libperl.lib overrides |
| 279 | some C RTL functions, they are correctly resolved when mentioned |
| 280 | in f1.obj and f2.obj. However, the resolution for libr1.lib and |
| 281 | libr2.lib is implementation-dependent. |
| 282 | |
| 283 | With -Zomf linking the symbols are resolved for libr1.lib and |
| 284 | libr2.lib *only if* they reside in .obj-file-sections of libperl.lib |
| 285 | which were already "picked up" for symbols in f1.obj f2.obj. |
| 286 | However, libperl.lib is an import library for a .DLL, so *each |
| 287 | symbol in libperl.lib sits in its own pseudo-section*! |
| 288 | |
| 289 | Corollary: only those symbol from libperl.lib which were already |
| 290 | mentioned in f1.obj f2.obj would be used for libr1.lib and |
| 291 | libr2.lib. Example: if f1.obj f2.obj do not mention calloc() but |
| 292 | libr1.lib and libr2.lib do, then .lib's will get calloc() of C RTL, |
| 293 | not one of libperl.lib. |
| 294 | |
| 295 | Solution: create a small duplicate of libperl.lib with overriding |
| 296 | symbols only. Put it *after* -llibr1 -llibr2 on the link line. |
| 297 | Map strdup() and putenv() to Perl_strdup() and Perl_putenv() |
| 298 | inside this library. |
| 299 | |
| 300 | Resolved: rmdir() and mkdir() do not accept trailing slashes. |
| 301 | Wrappers are implemented. |
| 302 | Resolved: when loading modules, FP mask may be erroneously changed by |
| 303 | _DLLInitTerm() (e.g., TCP32IP). |
| 304 | Solutions: a) dlopen() saves/restores the FP mask. |
| 305 | b) When starting, reset FP mask to a sane value |
| 306 | (if the DLL was compile-time linked). |
| 307 | New functions in package OS2: |
| 308 | unsigned _control87(unsigned new,unsigned mask) # as in EMX |
| 309 | unsigned get_control87() |
| 310 | # with default values good for handling exception mask: |
| 311 | unsigned set_control87_em(new=MCW_EM,mask=MCW_EM) |
| 312 | Needed to guard against other situations when the FP mask is |
| 313 | stompted upon. Apparently, IBM used a compiler (for some period |
| 314 | of time around '95?) which changes FP mask right and left... |
| 315 | Resolved: $^X was always uppercased (cosmetic). Solution: |
| 316 | use argv[0] if it differs from what the OS returns only in case. |
| 317 | Resolved: when creating PM message queues, WinCancelShutdown() was |
| 318 | not called even if the application said that it would not serve |
| 319 | messages in this queue. Could result in PM refusing to shutdown. |
| 320 | |
| 321 | Solution: resolve WinCancelShutdown at run time, keep the refcount |
| 322 | of who is going to serve the queue. |
| 323 | Resolved: Perl_Deregister_MQ() segfaulted (pid/tid not initialized). |
| 324 | Resolved: FillWinError() would not fetch the error. |
| 325 | Solution: resolve WinGetLastError at run time, call it. |
| 326 | Resolved: OS2::REXX would ignore arguments given to a Perl function |
| 327 | imported into the REXX compartment via REXX_eval_with(). |
| 328 | Resolved: OS2::REXX would treat arguments given to a Perl function |
| 329 | imported into the REXX compartment via _register() as ASCIIZ |
| 330 | strings inside of binary strings. |
| 331 | Resolved: OS2::REXX did not document _register(). |
| 332 | Resolved: OS2::REXX would not report the error to REXX if an error |
| 333 | condition appeared during a call to Perl function from REXX |
| 334 | compartment. As a result, the return string was not initialized. |
| 335 | A complete example of a mini-application added to OS2::REXX. |
| 336 | README.os2 updated to reflect the current state of Perl. |
| 337 | |
| 338 | pre 5.7.2: |
| 339 | aout build: kid bootstrap_* were not associated with XS. |
| 340 | bldlevel did not contain enough info. |
| 341 | extLibpath* was failing on the call of the second type. |
| 342 | Configure defines flushNULL now (EMX -Zomf bug broke autodetection). |
| 343 | Configure did not find SIGBREAK. |
| 344 | extLibpath supports LIBSTRICT, better error detection. |
| 345 | crypt() used if present in -lcrypt or -lufc. |
| 346 | dumb getpw*(), getgr*() etc. supported; as in EMX, but if no |
| 347 | $ENV{PW_PASSWD}, the passwd field contains a string which |
| 348 | cannot be returned by crypt() (for security reasons). |
| 349 | The unwound recursion in detecting executable by script was |
| 350 | using static buffers. Thus system('pod2text') would fail if the |
| 351 | current directory contained an empty file named 'perl'. |
| 352 | Put ordinals in the base DLL. |
| 353 | Enable EXE-compression. |
| 354 | Load time (ms): Without /e:2: 70.6; With /e:2: 75.3; Lxlite: 62.8 |
| 355 | Size drops from 750K to 627K, with lxlite to 515K. |
| 356 | lxlite /c:max gives 488K, but dumps core in t/TEST |
| 357 | os2ish.h defines SYSLOG constants ==> Sys::Syslog works. |
| 358 | Corrected warnings related to OS/2 code. |
| 359 | At one place = was put instead of ==. |
| 360 | Setting $^E should work. |
| 361 | Force "SYS0dddd=0xbar: " to error messages and to dlerror(). |
| 362 | ($^E == 2 printed SYS0002 itself, but 110 did not.) |
| 363 | $OS2::nsyserror=0 switches off forcing SYSdddd on $^E. |
| 364 | perl_.exe does not require PM dlls any more (symbols resolved at |
| 365 | runtime on the as needed basis). |
| 366 | OS2::Process: |
| 367 | get/set: term size; codepages; screen's cursor; screen's contents |
| 368 | reliable session name setting; |
| 369 | process's parent pid, and the session id; |
| 370 | switching to and enumeration of sessions |
| 371 | window hierarchy inspection |
| 372 | post a message to a window |
| 373 | More robust getpriority() on older Warps. |
| 374 | |
| 375 | New C APIs for runtime loading of entry points from DLLs |
| 376 | (useful for entry points not present on older versions of |
| 377 | OS/2, or with DLLs not present on floppy-boot stripped down |
| 378 | setups): CallORD(), DeclFuncByORD(), DeclVoidFuncByORD(), |
| 379 | DeclOSFuncByORD(), DeclWinFuncByORD(), AssignFuncPByORD(). |
| 380 | |
| 381 | pre 5.7.3: |
| 382 | Testing with PERL_TEST_NOVREXX=1 in environment makes tests |
| 383 | noninteractive (VREXX test requires pressing a button on a dialog). |
| 384 | |
| 385 | New (ugly and voodooish) hack to work around a bug in EMX |
| 386 | runtime architecture: |
| 387 | |
| 388 | EMX.DLL is *not* initialized from its _DLL_InitTerm() |
| 389 | routine, but the initialization is postponed until |
| 390 | immediately before main() is called by the principal |
| 391 | executable (may be the initialization also happens during |
| 392 | InitTerm of -Zso -Zsys DLLs?). The only reason I can see is |
| 393 | to postpone the initialization until the "layout" structure |
| 394 | is available, so the type of the executable is known. |
| 395 | [Instead, one should have broken the initialization into two |
| 396 | steps, with no-layout-known initialization ASAP, and the |
| 397 | finishing touch done when "layout" is known.] |
| 398 | |
| 399 | It is due to this hack that -Zsys, -Zso etc. are needed so |
| 400 | often. |
| 401 | |
| 402 | If during initialization of the Perl runtime environment we |
| 403 | discover that EMX environment is not set up completely, this |
| 404 | can be because of either our DLL being called from an |
| 405 | uncompatible flavor of EMX executable, or from an |
| 406 | unrelated-to-EMX.DLL (e.g., -Zsys or compiled with a |
| 407 | different compiler) executable. In the first case only the |
| 408 | CRTL is not completely initialized, in the other case |
| 409 | EMX.DLL may be not initialized too. |
| 410 | |
| 411 | We detect which of these two situations takes place, then |
| 412 | explicitly call the initialization entry points of EMX.DLL |
| 413 | and of CRT. The large caveat is that the init-entry point |
| 414 | of EMX.DLL also moves the stack pointer (another defect of |
| 415 | EMX architecture, the init() and |
| 416 | set_exception_handlers_on_stack() entry points should have |
| 417 | been separated). Thus we need some inline-assembler to |
| 418 | compensate for this, and need to remove the installed |
| 419 | exception handler - it is useless anyway, since exception |
| 420 | handlers need to be on the stack. [This one is on the |
| 421 | stack, but will be overwritten on exit from the function.] |
| 422 | |
| 423 | We also install an extra hack to run our atexit() handlers |
| 424 | on termination of the process (since the principal |
| 425 | executable does not know about *this* CRTL, we need to do it |
| 426 | ourselves - and longjmp() out of the chain of exception |
| 427 | handlers at a proper moment :-(). |
| 428 | |
| 429 | The net result: Perl DLL can be now used with an arbitrary |
| 430 | application. PERLREXX DLL is provided which makes Perl usable |
| 431 | from any REXX-enabled application. |
| 432 | |
| 433 | New test targets added to test how well Perl DLL runs with |
| 434 | different flavors of executables (see all_harness etc). To |
| 435 | avoid waiting for the user button press, run with env |
| 436 | PERL_TEST_NOVREXX=1. |
| 437 | |
| 438 | Another hack: on init of Perl runtime environment, the |
| 439 | executable is tested for being an aout EMX executable. The |
| 440 | test is the same done by gdb, so although this test is very |
| 441 | voodoo, it should be pretty robust (the beginning of the |
| 442 | executable code - at 0x10000 - is tested for a known bit |
| 443 | pattern). The result is used to set $OS2::can_fork, which is |
| 444 | eventually used to set $Config::Config{can_fork}. |
| 445 | |
| 446 | REXX::eval_REXX() made reenterable. ADDRESS PERLEVAL |
| 447 | available for the run REXX code. PERLLASTERROR available. |
| 448 | |
| 449 | A .map file is created for the .dll. Now easier to debug the |
| 450 | failures which do not happen with a debugging executable. |
| 451 | |
| 452 | Duplicate libperl.lib as perl.lib etc. to make Embed happier. |
| 453 | |
| 454 | File::Spec better adjusted to OS/2 (still does not support aa:/dir/). |
| 455 | |
| 456 | New module OS::Process::Const with necessary constants for the |
| 457 | Perl calls which mimic OS/2 API calls. |
| 458 | |
| 459 | After @14577: |
| 460 | $Config{pager} better (but needs work in the binary installer!). |
| 461 | |
| 462 | New API: OS2::DLLname([type], [\&sub]) |
| 463 | |
| 464 | New OS2::Process APIs: |
| 465 | |
| 466 | process_hwnd winTitle_set winTitle swTitle_set bothTitle_set |
| 467 | hWindowPos hWindowPos_set DesktopWindow |
| 468 | ActiveWindow_set |
| 469 | EnableWindow EnableWindowUpdate IsWindowEnabled |
| 470 | IsWindowVisible IsWindowShowing WindowPtr WindowULong |
| 471 | WindowUShort SetWindowBits SetWindowPtr |
| 472 | SetWindowULong |
| 473 | SetWindowUShort MPFROMSHORT MPVOID MPFROMCHAR |
| 474 | MPFROM2SHORT |
| 475 | MPFROMSH2CH MPFROMLONG |
| 476 | |
| 477 | OS::Process::Const symbols exportable from OS::Process too. |
| 478 | |
| 479 | OS::Process: prototypes on subroutines which do not naturally |
| 480 | take "vectors" as arguments (not backwards compatible!). |
| 481 | |
| 482 | New C API: SaveCroakWinError(), WinError_2_Perl_rc, |
| 483 | DeclWinFuncByORD_CACHE(), DeclWinFuncByORD_CACHE_survive(), |
| 484 | DeclWinFuncByORD_CACHE_resetError_survive(), |
| 485 | DeclWinFunc_CACHE(), DeclWinFunc_CACHE_resetError(), |
| 486 | DeclWinFunc_CACHE_survive(), |
| 487 | DeclWinFunc_CACHE_resetError_survive(); many new OS2 entry |
| 488 | points conveniently available via wrappers which will do the |
| 489 | necessary run-time dynalinking. |
| 490 | |
| 491 | After @15047: |
| 492 | makes PerlIO preserve the binary/text mode of filehandles |
| 493 | chosen by CRT library. (However, TTY handles still are not |
| 494 | clean, since switching them to TERMIO mode and back changes |
| 495 | the NL translation law at runtime, and PerlIO level does not |
| 496 | know this.) |
| 497 | |
| 498 | After @18156: |
| 499 | mkdir() rmdir() tolerate trailing slashes. |
| 500 | "localized" morphing to PM when already morphed would unmorph at end. |
| 501 | Convert \n to \r\n in REXX commands (Classic REXX would allow \r and |
| 502 | \r\n, but not \n as line-ends). |
| 503 | |
| 504 | After @19053: |
| 505 | Better detection of OS/2 in Configure scripts (if c:/ is not readable). |
| 506 | Better Configure support for \\ inside cpp-emited # lineno "filename". |
| 507 | Export pthread-support functions from threaded DLL. |
| 508 | [older change] If perl5.def file is present, the new perl5.def has |
| 509 | compatible ordinals. |
| 510 | OS/2 code compiles with threads enabled; much more robust pthreads |
| 511 | emulation (but some statics still present); survives fork(). |
| 512 | New attributes supported with [f]stat() and chmod() |
| 513 | archived is 0x1000000 = 0100000000 |
| 514 | hidden is 0x2000000 = 0200000000 |
| 515 | system is 0x4000000 = 0400000000 |
| 516 | If extra flag 0x8000000 = 01000000000 is missing during |
| 517 | chmod(), these 3 flags are ignored; this extra flag |
| 518 | is set in the result of stat() [this provides backward |
| 519 | compatibility, as well as transparency of stat()/ |
| 520 | chmod() supporting DOSISH]. |
| 521 | OS/2-specific modules use XSLoader now. |
| 522 | Remove DLLs manually after failing build (link386 would not?!). |
| 523 | Special-case stat()ing "/dev/nul" and "/dev/null" too. |
| 524 | Update dlopen() and friends: preserve i387 flags, better error messages, |
| 525 | support name==NULL (load for "this" DLL); |
| 526 | OS2::DLL does not eval() generated functions, uses closes instead; |
| 527 | new method wrapper_REXX() for DLL objects. |
| 528 | |
| 529 | After @19774: |
| 530 | Use common typemap for OS2:: modules. |
| 531 | New test file os2/perlrexx.cmd (should be run manually; does not it |
| 532 | exit too early???). |
| 533 | Export fork_with_resources(), croak_with_os2error() from DLL. |
| 534 | usleep() availability put in %Config{}. |
| 535 | Combine most (but not all!) statics into one struct. |
| 536 | New load-on-demand C functions |
| 537 | Dos32QueryHeaderInfo |
| 538 | DosTmrQueryFreq |

| 572 | WinFlashWindow |
| 573 | WinLoadPointer |
| 574 | WinQuerySysPointer |
| 575 | Check "\\SEM32\\PMDRAG.SEM" before loading PM-specific DLLs. |
| 576 | Handling of system {realname} was not correct in presence of |
| 577 | exe-type deduction, #!-emulation etc. |
| 578 | Use optimized PUSHTARG etc. XSUB convention. |
| 579 | $^E stringification contains PMERR_INVALID_HWND, PMERR_INVALID_HMQ, |
| 580 | PMERR_CALL_FROM_WRONG_THREAD, PMERR_NO_MSG_QUEUE, |
| 581 | PMERR_NOT_IN_A_PM_SESSION if these errors are not in .MSG file |
| 582 | (at least on Warp3fp42). |
| 583 | PERLLIB_PREFIX augmented by PERLLIB_582_PREFIX, PERLLIB_58_PREFIX, |
| 584 | PERLLIB_5_PREFIX (example for 5.8.2, the first one present is |
| 585 | considered). |
| 586 | New flag bit 0x2 for OS2::MorphPM(): immediately unmorph after creation |
| 587 | of message queue. |
| 588 | (De)Registring MQ preserves i386 flags. |
| 589 | When die()ing inside OS2:: API, include $^E in the message. |
| 590 | New function OS2::Timer(): returns Tmr-timer ticks (about 1MHz) since |
| 591 | start of OS/2, converted to number of seconds (keep in mind |
| 592 | that this timer uses a different crystal than the real-time |
| 593 | clock; thus these values have only weak relationship to the |
| 594 | wall clock time; behaviour with APM on is not defined). |
| 595 | New function OS2::DevCap() [XXX Wrong usage message!!!] |
| 596 | Usage: OS2::DevCap([WHAT, [HOW=0]]); the default for WHAT is |
| 597 | the memory device context, WHAT should be a device context |
| 598 | (as integer) if HOW==0 and a window handle (as integer) if |
| 599 | HOW==1. Returns a hash with keys |

| 641 | Support new keys NUMPROCESSORS MAXHPRMEM MAXHSHMEM MAXPROCESSES |
| 642 | VIRTUALADDRESSLIMIT INT10ENABLE from OS2::SysInfo(); support |

| 647 | addition to old mod_name_handle = 0, mod_name_shortname = 1, |
| 648 | mod_name_full = 2 for OS2::DLLname(flag, cv); use an address |
| 649 | (as integer) or module handle instead of cv. |
| 650 | New function OS2::_headerInfo(req,size[,handle,[offset]]). |
| 651 | New function OS2::libPath(); returns the value of LIBPATH. |
| 652 | New function OS2::mytype(which=0) to query current process type: |
| 653 | 0: type immediately after startup or last fork(); |
| 654 | 1: type immediately after startup; |
| 655 | 2: type before the first morphing; |
| 656 | 3: type as set now in the header. |
| 657 | New function OS2::mytype_set(type); |
| 658 | New function OS2::incrMaxFHandles(delta = 0); returns updated value |
| 659 | for the possible number of open file descriptors. |
| 660 | Make check_emx_runtime() thread-safe. |
| 661 | Fix float-to-string conversion in the range .0001..0.1 (would return |
| 662 | in exponential notation, per gcvt()). |
| 663 | Make fork(): a) preserve i387 flags; |
| 664 | b) preverve the dynamically loaded (system) DLLs; |
| 665 | c) preserve morphed status; |
| 666 | Make sleep() work with time > 0xffffffff/1000. |
| 667 | Implement usleep() via _sleep2(); make select() with num_files==0 |
| 668 | thread-safe (via calling DosSleep()). |
| 669 | OS2::Process::Const() manages (MB|MBID|CF|CFI|SPTR)_.* constants too. |
| 670 | New (exported) functions from OS2::Process (some undocumented???): |

| 709 | New method OS2::DLL->module() (to replace botched ->new() method). |
| 710 | New functions call20(), call20_p(), call20_rp3(), call20_rp3_p(), |
| 711 | call20_Dos(), call20_Win(), call20_Win_0OK(), |
| 712 | call20_Win_0OK_survive() in OS2::DLL to call C functions via |
| 713 | pointers. |
| 714 | |
| 715 | After @20218: |
| 716 | select() workaround broke build of x2p. |
| 717 | New OS2::Process (exported, undocumented) functions: |
| 718 | kbdChar |
| 719 | kbdhChar |
| 720 | kbdStatus |
| 721 | _kbdStatus_set |

| 732 | vioFont |
| 733 | vioFont_set |
| 734 | Make CheckOS2Error() macro return the error code. |
| 735 | New dynaloaded entry point DosReplaceModule(). |
| 736 | New function OS2::replaceModule(target [, source [, backup]]). |
| 737 | |
| 738 | After @21211: |
| 739 | Make Cwd::sys_abspath() default to '.' and taint the result. |
| 740 | Fix os2_process*.t to work if the default for VIO windows is maximized. |
| 741 | Fix to avoid non-existing PIDs for get_sysinfo() broke pid==0. |
| 742 | Restore default mode for pipes to be TEXT mode. |
| 743 | |
| 744 | After @21379: |
| 745 | New OS2::Process functions: __term_mirror_screen() __term_mirror() |
| 746 | io_term(). |
| 747 | Fix a.out build: special-case thread::shared, pick up all the build |
| 748 | static libraries, not only those for top-level modules. |
| 749 | Fix DLLname() test to work with the static build too. |
| 750 | New dynaloaded entry point RexxRegisterSubcomExe(); make OS2::REXX use |
| 751 | it so it is not linked with REXX*.DLLs any more. |
| 752 | If system "./foo", and empty "./foo" and "./foo.exe" exist, |
| 753 | argv[0] would be set to junk. |
| 754 | Make perl2cmd convert .pl files and keep the command-line switches. |
| 755 | Make XSLoader and Perl-specific parts of DynaLoader to die with static |
| 756 | builds (new variable $OS2::is_static used); |
| 757 | Move perlmain.obj to the DLL; export main() as dll_perlmain(); create |
| 758 | a library libperl_dllmain to translate the exported symbol |
| 759 | back to main(); link the executables with this library instead |
| 760 | of perlmain.obj. |
| 761 | Add /li to link386's options (line number info in the .map file). |
| 762 | Another break from fix to avoid non-existing PIDs for get_sysinfo(). |
| 763 | |
| 764 | After @21574: |
| 765 | Update import libraries when perl version changes (e.g., due to rsync). |
| 766 | New exported symbols dup() and dup2() [the wrappers have workaround |
| 767 | for off-by-one error + double fault in the pre-Nov2003 kernels |
| 768 | when a (wrong) filedescriptor which is limit+1 is dup()ed]. |
| 769 | Enable disabling fd via a FILE* (to avoid close() during fclose()). |
| 770 | New dynaloaded entry point DosPerfSysCall(). |
| 771 | New function OS2::perfSysCall(cmd = CMD_KI_RDCNT, ulParm1= 0, |
| 772 | ulParm2= 0, ulParm3= 0); when called |
| 773 | with cmd == CMD_KI_RDCNT = 0x63 and no other parameters, |
| 774 | returns: in the scalar context: the tick count of processor 1; |
| 775 | in the list context: 4 tick counts per processor: |
| 776 | total/idle/busy/interrupt-time. |
| 777 | with cmd == CMD_KI_GETQTY == 0x41 and no other parameters, |
| 778 | returns the CPU count. Currently in other cases the return |
| 779 | is void. |
| 780 | New executables perl___<number> generated with decreased stack size |
| 781 | (good when virtual memory is low; e.g. floppy boot). |
| 782 | |
| 783 | After 5.8.2 (@21668): |
| 784 | Fixes to installperl scripts to avoid junk output, allow overwrite |
| 785 | of existing files (File::Copy::copy is mapped to DosCopy() |
| 786 | with flags which would not overwrite). |
| 787 | Disable DynaLoading of Perl modules with AOUT build (will core anyway). |
| 788 | For AOUT build: Quick hack to construct directories necessary for |
| 789 | /*/% stuff [maybe better do it from hints/os2.sh?]. |
| 790 | AOUT build: do -D__ST_MT_ERRNO__ to simplify linking with -Zmtd |
| 791 | (e.g., to test GD: gd.dll linked with -Zmtd). |
| 792 | MANIFEST.SKIP was read without a drive part of the filename. |
| 793 | Rename Cwd::extLibpath*() to OS2::... (old names still preserved). |
| 794 | Install perl.lib and perl.a too. |
| 795 | New methods libPath_find(),has_f32(),handle(),fullname() for OS2::DLL. |
| 796 | Enable quad support using long long. |
| 797 | New C exported functions os2_execname(), async_mssleep(), msCounter(), |
| 798 | InfoTable(), dir_subst(), Perl_OS2_handler_install(), |
| 799 | fill_extLibpath(). |
| 800 | async_mssleep() uses some undocumented features which allow usage of |
| 801 | highest possible resolution of sleep() while preserving low |
| 802 | priority (raise of resolution may be not available before |
| 803 | Warp3fp40; resolution is 8ms/CLOCK_SCALE). |
| 804 | usleep() and select(undef,undef,undef,$t) are using this |
| 805 | interface for time up to 0.5sec. |
| 806 | New convenience macros os2win_croak_0OK(rc,msg), os2win_croak(rc,msg), |
| 807 | os2cp_croak(rc,msg). |
| 808 | Supports ~installprefix, ~exe, ~dll in PERLLIB_PREFIX etc (actual |
| 809 | directories are substituted). |
| 810 | New functions OS2::msCounter(), OS2::ms_sleep(), OS2::_InfoTable(). |
| 811 | Checks stack when fixing EMX being under-initialized (-Zomf -Zsys |
| 812 | produces 32K stack???). |
| 813 | New environment variables PERL_BEGINLIBPATH, PERL_PRE_BEGINLIBPATH, |
| 814 | PERL_POST_BEGINLIBPATH, PERL_ENDLIBPATH, |
| 815 | PERL_PRE_ENDLIBPATH PERL_POST_ENDLIBPATH (~-enabled); |
| 816 | PERL_EMXLOAD_SECS. |
| 817 | Better handling of FIRST_MAKEFILE (propagate to subdirs during test, |
| 818 | do not require Makefile.PL present). |
| 819 | perl2cmd converter: do not rewrite if no change. |
| 820 | README.os2 updated with info on building binary distributions and |
| 821 | custom perl executables (but not much else). |
