2 | PERLLIB_PREFIX was not active if it matches an element of @INC | |
3 | as a whole. | |
4 | Do not need PERL_SBRK if crtdll-revision is >= 50. | |
5 | Use -Zsmall-conv if crtdll-revision is >= 50 (in static perl!). | |
6 | :7: warning: #warning <dirent.h> requires <sys/types.h> | |
7 | We compile miniperl static. It cannot fork, thus there may be | |
8 | problems with pipes (since HAS_FORK is in | |
9 | place). Pipes are required by makemaker. | |
10 | We compile perl___.exe A.OUT and dynamic. It should be able to | |
11 | fork. | |
12 | If we can fork, we my_popen by popen unless "-|". Thus we | |
13 | write a cooky "-1" into the pid array to indicate | |
14 | this. | |
15 | Apparently we can fork, and we can load dynamic extensions | |
16 | now, though probably not simultaneously. | |
17 | *DB tests corrected for OS/2 one-user stat[2]. | |
18 | /bin/sh is intercepted and replaced by SH_PATH. | |
19 | Note that having '\\' in the command line of one-arg `system' | |
20 | would trigger call via shell. | |
21 | Segfault with system {'ls'} 'blah'; corrected. | |
22 | Documentation of OS/2-different features added to main PODs. | |
23 | New buitins in Cwd:: | |
24 | ||
25 | Cwd::current_drive | |
26 | Cwd::sys_chdir - leaves drive as it is. | |
27 | Cwd::change_drive | |
28 | Cwd::sys_is_absolute - has drive letter and is_rooted | |
29 | Cwd::sys_is_rooted - has leading [/\\] (maybe | |
30 | after a drive) | |
31 | Cwd::sys_is_relative - changes with current dir | |
32 | Cwd::sys_cwd - Interface to cwd from EMX. | |
33 | Cwd::sys_abspath(name, dir) | |
34 | - Really really odious | |
35 | function. Returns absolute | |
36 | name of file which would | |
37 | have 'name' if CWD were 'dir'. | |
38 | Dir defaults to the current dir. | |
39 | Cwd::extLibpath [type] - Get/set current value of extended | |
40 | Cwd::extLibpath_set - library search path. | |
41 | path [type] | |
42 | The optional last argument redirects | |
43 | to END-path if true, | |
44 | default is to search BEGIN-path. | |
45 | (Note that some of these may be moved to different | |
46 | libraries - eventually). | |
47 | Executables: | |
48 | perl - can fork, can dynalink (but not simultaneously) | |
49 | perl_ - can fork, cannot dynalink | |
50 | perl__ - same as perl___, but PM. | |
51 | perl___ - cannot fork, can dynalink. | |
52 | The build of the first one - perl - is rather convoluted, and | |
53 | requires a build of miniperl_. | |
55497cff | 54 | |
55 | after 5.003_07: | |
56 | custom tmpfile and tmpname which may use $TMP, $TEMP. | |
57 | all the calls to OS/2 API wrapped so that it is safe to use | |
58 | them under DOS (may die(), though). | |
59 | Tested that popen works under DOS with modified PDKSH and RSX. | |
60 | File::Copy works under DOS. | |
61 | MakeMaker modified to work under DOS (perlmain.c.tmp and sh -c true). | |
72ea3524 IZ |
62 | |
63 | after 5.003_08: | |
64 | OS2::PrfDB exports symbols as documented; | |
65 | should work on OS/2 2.1 again. | |
66 | uses reliable signals when spawing. | |
67 | do not use popen() any more - no intermediate shell unless needed. | |
df3ef7a9 IZ |
68 | |
69 | after 5.003_11: | |
70 | Functions emx_{malloc,realloc,calloc,free} are exported from DLL. | |
71 | get_sysinfo() bugs corrected (flags were not used and wrongly defined). | |
44a8e56a | 72 | |
73 | after 5.003_20: | |
74 | _isterm is substituted instead of isatty, s?random instead of srand. | |
75 | `register' disabled if -DDEBUGGING and not AOUT build: stupid SD386. | |
76 | 3-argument select() was stomping over memory. | |
e29f6e02 IZ |
77 | |
78 | after 5.003_21: | |
79 | Can start scripts by executing 'dir/script' and | |
80 | 'script.sh'. Form without extension will call shell only if | |
81 | the specified file exists (will not look on path) (to prohibit | |
82 | trying to run shell commands directly). - Needed by magic.t. | |
aa689395 | 83 | |
84 | after 5.003_27: | |
85 | ALTERNATE_SHEBANG="extproc " supported, thus options on this | |
86 | line are processed (possibly twice). -S is made legal on such | |
87 | a line. This -S -x is not needed any more. | |
88 | perl.dll may be used from non-EMX programs (via PERL_SYS_INIT | |
89 | - the caller should have valid variable "env" with | |
90 | environment). Known problems: $$ does not work - is 0, waitpid | |
91 | returns immediately, thus Perl cannot wait for completion of | |
92 | started programs. | |

367f3c24 IZ |
94 | after 5.004_01: |
95 | flock emulation added (disable by setting env PERL_USE_FLOCK=0), | |
96 | thanks to Rocco Caputo; | |
97 | RSX bug with missing waitpid circomvented; | |
98 | -S bug with full path with \ corrected. | |
99 | ||
d8c2d278 IZ |
100 | before 5.004_02: |
101 | -S switch to perl enables a search with additional extensions | |
102 | .cmd, .btm, .bat, .pl as well. This means that if you have | |
103 | mycmd.pl or mycmd.bat on PATH, | |
104 | perl -S mycmd | |
105 | will work. Perl will also look in the current directory first. | |
106 | Moreover, a bug with \; in PATH being non-separator is fixed. | |
84902520 | 107 | |
fb73857a | 108 | after 5.004_03: |
109 | $^E tracks calls to CRT now. (May break if Perl masks some | |
110 | changes to errno?) | |
111 | $0 may be edited to longer lengths (at least under OS/2). | |
112 | OS2::REXX->loads looks in the OS/2-ish fashion too. | |

91643db9 IZ |
114 | after 5.004_04: |
115 | Default perl.exe was built with a shorter stack than expected. | |
116 | Strip extensions DLLs too (unless debugging build). | |
117 | ./os2.c being RO could stop cp. | |
118 | When starting scripts, Perl will find them on path (using the same | |
119 | extensions as for -S command-line switch). If it finds magic | |
120 | `extproc ' or `#!' cookies, it will start the scripts directly. | |
121 | May use `cmd /c more <' as a pager. | |
122 | If a program could not be started, this might have been hidden. | |
123 | End of pipe was closed twice when `open'ing a pipeline. | |
124 | ||
dd96f567 IZ |
125 | after 5.004_53: |
126 | Minimal thread support added. One needs to manually move pthread.h | |
3aefca04 IZ |
127 | |
128 | after 5.004_64: | |
129 | Make DLL names different if thread-enabled. | |
130 | Emit more informative internal DLL descriptions. | |
2c2e0e8c IZ |
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. | |
017f25f1 IZ |
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. | |

163 | after 5.005_53: | |
e96326af IZ |
164 | Would segfault system()ing non-existing program; |
165 | AOUT build was hosed; | |
4bfbfac5 IZ |
166 | warning-test for getpriority() might lock the system hard on |
167 | pre-fixpak22 configuration (calling getpriority() on | |
168 | non-existing process triggers a system-wide bug). | |
169 | ||
4e3d4845 IZ |
170 | |
171 | PrfDB was using a bug in processing XSUBs returning U32. | |
172 | ||
4bfbfac5 IZ |
173 | Variable $OS2::emx_rev implemented (string and numberic values |
174 | are the same as C variables _emx_rev and _emx_vprt). | |
175 | Variable $OS2::emx_env implemented (same as C variable _emx_env). | |
176 | Variable $OS2::os_ver implemented (_osmajor + 0.001 * _osminor). | |
177 | ||
178 | Improved centralized management of HAB and HMQ. To get Perl's | |
179 | HAB, call perl_hab_GET(). (After the initial call one | |
180 | can use Perl_hab instead.) To require Perl's HMQ, | |
181 | call perl_hmq_GET(), to release it call perl_hmq_UNSET(), | |
182 | to obtain it between these calls use Perl_hmq. | |
183 | HMQ management is refcounted, and the program will morph | |
184 | itself into/from PM if required. | |
185 | If perl.h cannot be included, hab may be obtained by Perl_hab_GET(). | |
186 | ||
187 | New function OS2::Error(do_harderror,do_exception). Returns | |
188 | undef if it was not called yet, otherwise bit 1 is | |
189 | set if on previous call do_harderror was enabled, bit | |
190 | 2 is set if if on previous call do_exception was enabled. | |
191 | This function enables/disables error popups associated with | |
192 | hardware errors (Disk not ready etc.) and software exceptions. | |
193 | ||
194 | New function OS2::Errors2Drive(drive). Returns undef if it was | |
195 | not called yet, otherwise return false if Errors were | |
196 | not requested to be written to a hard drive, or the | |
197 | drive letter if this was requested. | |
198 | This function may redirect error popups associated with | |
199 | hardware errors (Disk not ready etc.) and software exceptions | |
200 | to the file POPUPLOG.OS2 at the root directory of the | |
201 | specified drive. Overrides OS2::Error() specified by | |
202 | individual programs. Given argument undef will | |
203 | disable redirection. Has global effect, persists | |
204 | after the application exits. | |
205 | ||
206 | New function OS2::SysInfo(). Returns a hash with system information. | |
207 | The keys of the hash are | |
208 | ||
209 | MAX_PATH_LENGTH, MAX_TEXT_SESSIONS, MAX_PM_SESSIONS, | |
210 | MAX_VDM_SESSIONS, BOOT_DRIVE, DYN_PRI_VARIATION, | |
211 | MAX_WAIT, MIN_SLICE, MAX_SLICE, PAGE_SIZE, | |
212 | VERSION_MAJOR, VERSION_MINOR, VERSION_REVISION, | |
213 | MS_COUNT, TIME_LOW, TIME_HIGH, TOTPHYSMEM, TOTRESMEM, | |
214 | TOTAVAILMEM, MAXPRMEM, MAXSHMEM, TIMER_INTERVAL, | |
215 | MAX_COMP_LENGTH, FOREGROUND_FS_SESSION, | |
216 | FOREGROUND_PROCESS | |
217 | ||
218 | New function OS2::BootDrive(force). Returns a letter without colon. | |
219 | ||
220 | New functions OS2::MorphPM(serve)/OS2::UnMorphPM(serve). Transforms | |
221 | the current application into a PM application and back. | |
222 | The argument true means that a real message loop is | |
223 | going to be performed. | |
224 | OS2::MorphPM() returns the PM message queue handle as an integer. | |
225 | ||
226 | New function OS2::Serve_Messages(force). Fake on-demand | |
227 | retrieval of outstanding PM messages. If force is false, | |
228 | will not dispatch messages if a real message loop is known to | |
229 | be present. Returns number of messages retrieved. | |
230 | Dies with "QUITing..." if WM_QUIT message is obtained. | |
231 | ||
232 | New function OS2::Process_Messages(force [, cnt]). Retrieval | |
233 | of PM messages until window creation/destruction. | |
234 | If force is false, will not dispatch messages | |
235 | if a real message loop is known to be present. | |
236 | Returns change in number of windows. If cnt is given, | |
237 | it is incremented by the number of messages retrieved. | |
238 | Dies with "QUITing..." if WM_QUIT message is obtained. | |
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. | |

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>; | |

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. | |

273 | pre 5.6.1: | |
274 | Resolved: "Bad free()" messages (e.g., from DB_File) with -Zomf build. | |
275 | The reason was: when an extension DLL was linked, the order of | |
276 | libraries was similar to this: | |
277 | f1.obj f2.obj libperl.lib -llibr1 -llibr2 | |
278 | (with C RTL implicitly after this). When libperl.lib overrides | |
279 | some C RTL functions, they are correctly resolved when mentioned | |
280 | in f1.obj and f2.obj. However, the resolution for libr1.lib and | |
281 | libr2.lib is implementation-dependent. | |
282 | ||
283 | With -Zomf linking the symbols are resolved for libr1.lib and | |
284 | libr2.lib *only if* they reside in .obj-file-sections of libperl.lib | |
285 | which were already "picked up" for symbols in f1.obj f2.obj. | |
286 | However, libperl.lib is an import library for a .DLL, so *each | |
287 | symbol in libperl.lib sits in its own pseudo-section*! | |
288 | ||
289 | Corollary: only those symbol from libperl.lib which were already | |
290 | mentioned in f1.obj f2.obj would be used for libr1.lib and | |
291 | libr2.lib. Example: if f1.obj f2.obj do not mention calloc() but | |
292 | libr1.lib and libr2.lib do, then .lib's will get calloc() of C RTL, | |
293 | not one of libperl.lib. | |
294 | ||
295 | Solution: create a small duplicate of libperl.lib with overriding | |
296 | symbols only. Put it *after* -llibr1 -llibr2 on the link line. | |
297 | Map strdup() and putenv() to Perl_strdup() and Perl_putenv() | |
298 | inside this library. | |
299 | ||
300 | Resolved: rmdir() and mkdir() do not accept trailing slashes. | |
301 | Wrappers are implemented. | |
302 | Resolved: when loading modules, FP mask may be erroneously changed by | |
303 | _DLLInitTerm() (e.g., TCP32IP). | |
304 | Solutions: a) dlopen() saves/restores the FP mask. | |
305 | b) When starting, reset FP mask to a sane value | |
306 | (if the DLL was compile-time linked). | |
307 | New functions in package OS2: | |
308 | unsigned _control87(unsigned new,unsigned mask) # as in EMX | |
309 | unsigned get_control87() | |
310 | # with default values good for handling exception mask: | |
311 | unsigned set_control87_em(new=MCW_EM,mask=MCW_EM) | |
312 | Needed to guard against other situations when the FP mask is | |
313 | stompted upon. Apparently, IBM used a compiler (for some period | |
314 | of time around '95?) which changes FP mask right and left... | |
315 | Resolved: $^X was always uppercased (cosmetic). Solution: | |
316 | use argv[0] if it differs from what the OS returns only in case. | |
317 | Resolved: when creating PM message queues, WinCancelShutdown() was | |
318 | not called even if the application said that it would not serve | |
319 | messages in this queue. Could result in PM refusing to shutdown. | |
320 | ||
321 | Solution: resolve WinCancelShutdown at run time, keep the refcount | |
322 | of who is going to serve the queue. | |
323 | Resolved: Perl_Deregister_MQ() segfaulted (pid/tid not initialized). | |
324 | Resolved: FillWinError() would not fetch the error. | |
325 | Solution: resolve WinGetLastError at run time, call it. | |
326 | Resolved: OS2::REXX would ignore arguments given to a Perl function | |
327 | imported into the REXX compartment via REXX_eval_with(). | |
328 | Resolved: OS2::REXX would treat arguments given to a Perl function | |
329 | imported into the REXX compartment via _register() as ASCIIZ | |
330 | strings inside of binary strings. | |
331 | Resolved: OS2::REXX did not document _register(). | |
332 | Resolved: OS2::REXX would not report the error to REXX if an error | |
333 | condition appeared during a call to Perl function from REXX | |
334 | compartment. As a result, the return string was not initialized. | |
335 | A complete example of a mini-application added to OS2::REXX. | |
335bd836 | 336 | README.os2 updated to reflect the current state of Perl. |
