after 5.003_05: PERLLIB_PREFIX was not active if it matches an element of @INC as a whole. Do not need PERL_SBRK if crtdll-revision is >= 50. Use -Zsmall-conv if crtdll-revision is >= 50 (in static perl!). :7: warning: #warning requires We compile miniperl static. It cannot fork, thus there may be problems with pipes (since HAS_FORK is in place). Pipes are required by makemaker. We compile perl___.exe A.OUT and dynamic. It should be able to fork. If we can fork, we my_popen by popen unless "-|". Thus we write a cooky "-1" into the pid array to indicate this. Apparently we can fork, and we can load dynamic extensions now, though probably not simultaneously. *DB tests corrected for OS/2 one-user stat[2]. /bin/sh is intercepted and replaced by SH_PATH.

Executables: perl - can fork, can dynalink (but not simultaneously) perl_ - can fork, cannot dynalink perl__ - same as perl___, but PM. perl___ - cannot fork, can dynalink. The build of the first one - perl - is rather convoluted, and requires a build of miniperl_. after 5.003_05: PERLLIB_PREFIX was not active if it matches an element of @INC as a whole.

The build of the first one - perl - is rather convoluted, and requires a build of miniperl_. after 5.003_07: custom tmpfile and tmpname which may use $TMP, $TEMP. all the calls to OS/2 API wrapped so that it is safe to use them under DOS (may die(), though). Tested that popen works under DOS with modified PDKSH and RSX. File::Copy works under DOS. MakeMaker modified to work under DOS (perlmain.c.tmp and sh -c true). after 5.003_08: OS2::PrfDB exports symbols as documented; should work on OS/2 2.1 again. uses reliable signals when spawing. do not use popen() any more - no intermediate shell unless needed. after 5.003_11: Functions emx_{malloc,realloc,calloc,free} are exported from DLL. get_sysinfo() bugs corrected (flags were not used and wrongly defined). after 5.003_20: _isterm is substituted instead of isatty, s?random instead of srand. `register' disabled if -DDEBUGGING and not AOUT build: stupid SD386. 3-argument select() was stomping over memory. after 5.003_21: Can start scripts by executing 'dir/script' and 'script.sh'. Form without extension will call shell only if the specified file exists (will not look on path) (to prohibit trying to run shell commands directly). - Needed by magic.t. after 5.003_27: ALTERNATE_SHEBANG="extproc " supported, thus options on this line are processed (possibly twice). -S is made legal on such a line. This -S -x is not needed any more. perl.dll may be used from non-EMX programs (via PERL_SYS_INIT - the caller should have valid variable "env" with environment). Known problems: $$ does not work - is 0, waitpid returns immediately, thus Perl cannot wait for completion of started programs. after 5.004_01: flock emulation added (disable by setting env PERL_USE_FLOCK=0), thanks to Rocco Caputo; RSX bug with missing waitpid circomvented; -S bug with full path with \ corrected. before 5.004_02: -S switch to perl enables a search with additional extensions .cmd, .btm, .bat, .pl as well. This means that if you have mycmd.pl or mycmd.bat on PATH, perl -S mycmd will work. Perl will also look in the current directory first. Moreover, a bug with \; in PATH being non-separator is fixed. after 5.004_03: $^E tracks calls to CRT now. (May break if Perl masks some changes to errno?) $0 may be edited to longer lengths (at least under OS/2). OS2::REXX->loads looks in the OS/2-ish fashion too. after 5.004_04: Default perl.exe was built with a shorter stack than expected. Strip extensions DLLs too (unless debugging build). ./os2.c being RO could stop cp. When starting scripts, Perl will find them on path (using the same extensions as for -S command-line switch). If it finds magic `extproc ' or `#!' cookies, it will start the scripts directly. May use `cmd /c more <' as a pager. If a program could not be started, this might have been hidden. End of pipe was closed twice when `open'ing a pipeline. after 5.004_53: Minimal thread support added. One needs to manually move pthread.h after 5.004_64: Make DLL names different if thread-enabled. Emit more informative internal DLL descriptions. 5.004_72: Updated OS2::Process (v0.2) included. after 5.004_73: Fixed a bug with argv not NULL-terminated when starting scripts. Support all the forms of starting scripts. Support killing a child when receiving a signal during system() (in two stage, on first send the same signal, on the next send SIGKILL). Add the same logic for scripts as in pdksh, including stripping the path from #! line if needed, calling EXECSHELL or COMSPEC for magic-less scripts; Now pdksh is called only if one-arg system()/friends contains metachars, or if magic-line asks for sh, or there is no magic line and EXECSHELL is set to sh. Shell is supplied the original command line if possible. after 5.005_02: Can start PM programs from non-PM sessions by plain system() and friends. Can start DOS/Win programs. Can start fullscreen programs from non-fullscreen sessions too. In fact system(P_PM,...) was broken. We mangle the name of perl*.DLL, to allow coexistence of different versions of Perl executables on the system. Mangling of names of extension DLL is also changed, thus running two different versions of the executable with loaded extensions should not lead to conflicts (since extension-full-name and Perl-version mangling work in the same set ot 576 possible keys, this may lead to clashes). $^E was reset on the second read, and contained ".\r\n" at the end.
