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_. | |
55497cff | 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. | |
df3ef7a9 IZ |
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). | |
44a8e56a | 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. | |
aa689395 | 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. | |

367f3c24 IZ |
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 | ||
d8c2d278 IZ |
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. | |
84902520 | 107 | |
fb73857a | 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. | |

91643db9 IZ |
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 | ||
dd96f567 IZ |
125 | after 5.004_53: |

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. | |

e96326af IZ |
164 | Would segfault system()ing non-existing program; |
165 | AOUT build was hosed; | |
4bfbfac5 IZ |
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 | ||
4e3d4845 IZ |
170 | |
171 | PrfDB was using a bug in processing XSUBs returning U32. | |
172 | ||
4bfbfac5 IZ |
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. | |

250 | Force Unix-domain sockets to start with "/socket", convert | |
251 | '/' to '\' in the calls; | |

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); | |

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. | |
335bd836 | 336 | README.os2 updated to reflect the current state of Perl. |

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 | |

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 | ||
25417810 | 462 | New API: OS2::DLLname([type], [\&sub]) |
c4e0013e IZ |
463 | |
464 | New OS2::Process APIs: | |
465 | ||

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: | |
c4e0013e IZ |
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.) | |
00e72b55 IZ |
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. | |

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 | |

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 | |

711 | call20_Dos(), call20_Win(), call20_Win_0OK(), | |
712 | call20_Win_0OK_survive() in OS2::DLL to call C functions via | |

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). |
