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

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

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!!!]
|

|
---|
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???):

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 |
|
---|
715 | After @20218:
|
---|
716 | select() workaround broke build of x2p.
|
---|
717 | New OS2::Process (exported, undocumented) functions:
|
---|

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).
