| 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.

|
|---|
| 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.
