1after 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 55after 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 63after 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 69after 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 73after 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 78after 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 84after 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 94after 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 circumvented; 98 -S bug with full path with \ corrected. 99 100before 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 108after 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 114after 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 125after 5.004_53: 126 Minimal thread support added. One needs to manually move pthread.h 127 128after 5.004_64: 129 Make DLL names different if thread-enabled. 130 Emit more informative internal DLL descriptions. 131 1325.004_72: 133 Updated OS2::Process (v0.2) included. 134 135after 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 149after 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 163after 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 numeric 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 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 240after 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 247after 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 257after 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 273pre 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 stomped 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 338pre 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 381pre 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 459After @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 491After @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 498After @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 504After @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 529After @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 539 DosTmrQueryTime 540 WinQueryActiveDesktopPathname 541 WinInvalidateRect 542 WinCreateFrameControl 543 WinQueryClipbrdFmtInfo 544 WinQueryClipbrdOwner 545 WinQueryClipbrdViewer 546 WinQueryClipbrdData 547 WinOpenClipbrd 548 WinCloseClipbrd 549 WinSetClipbrdData 550 WinSetClipbrdOwner 551 WinSetClipbrdViewer 552 WinEnumClipbrdFmts 553 WinEmptyClipbrd 554 WinAddAtom 555 WinFindAtom 556 WinDeleteAtom 557 WinQueryAtomUsage 558 WinQueryAtomName 559 WinQueryAtomLength 560 WinQuerySystemAtomTable 561 WinCreateAtomTable 562 WinDestroyAtomTable 563 WinOpenWindowDC 564 DevOpenDC 565 DevQueryCaps 566 DevCloseDC 567 WinMessageBox 568 WinMessageBox2 569 WinQuerySysValue 570 WinSetSysValue 571 WinAlarm 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.

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();

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) preserve 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???): 671 process_codepage_set 672 TopLevel 673 FocusWindow_set_keep_Zorder 674 ActiveDesktopPathname 675 InvalidateRect 676 CreateFrameControl 677 ClipbrdFmtInfo 678 ClipbrdOwner 679 ClipbrdViewer 680 ClipbrdData 681 OpenClipbrd 682 CloseClipbrd 683 ClipbrdData_set 684 ClipbrdOwner_set 685 ClipbrdViewer_set 686 EnumClipbrdFmts 687 EmptyClipbrd 688 AddAtom 689 FindAtom 690 DeleteAtom 691 AtomUsage 692 AtomName 693 AtomLength 694 SystemAtomTable 695 CreateAtomTable 696 DestroyAtomTable 697 _ClipbrdData_set 698 ClipbrdText 699 ClipbrdText_set 700 _MessageBox 701 MessageBox 702 _MessageBox2 703 MessageBox2 704 LoadPointer 705 SysPointer 706 Alarm 707 FlashWindow 708 Do not use AUTOLOAD in OS2::DLL; moved to OS2::DLL::dll. 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 715After @20218: 716 select() workaround broke build of x2p. 717 New OS2::Process (exported, undocumented) functions: 718 kbdChar 719 kbdhChar 720 kbdStatus 721 _kbdStatus_set 722 kbdhStatus 723 kbdhStatus_set 724 vioConfig 725 viohConfig 726 vioMode 727 viohMode 728 viohMode_set 729 _vioMode_set 730 _vioState 731 _vioState_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 738After @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 744After @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 764After @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 783After 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). 822
