1 | Revision history for Perl extension Time::HiRes. |
2 | |
170c5524 |
3 | 1.85 [2005-12-16] |
4 | - the interface to clock_nanosleep() is more natural |
5 | when it is like (hires) time() (instead of like nanosleep), |
6 | and the .xs implementation of clock_nanosleep() in 1.84 |
7 | was broken anyway |
8 | - the semantics of clock() are not quite so silly as I thought, |
9 | but still somewhat odd, documented as such |
10 | - additional enhancements to the clock() documentation |
11 | - add test for clock_nanosleep() (I cannot test this |
12 | since none of my systems have the function) |
13 | - add test for clock() |
14 | |
15 | 1.84 [2005-12-16] |
16 | - add clock() which returns the processor time in |
17 | (floating point) seconds since an arbitrary era |
18 | - add clock_nanosleep() which suspends the current |
19 | thread until either absolute time or for relative time |
20 | - [rt.cpan.org #16486] printf missing value in HiRes.t |
21 | - add constants CLOCKS_PER_SEC, CLOCK_SOFTTIME, TIMER_ABSTIME |
22 | - tiny typo fixes |
23 | |
a5929ff3 |
24 | 1.83 [2005-11-19] |
25 | - has_symbol() was wrong since e.g. ITIMER_VIRTUAL is exported |
26 | via @EXPORT_OK even when it is not available. This is heinous. |
27 | @EXPORT_OK should be determined at Makefile.PL time. |
28 | - be more lenient is testing clock_gettime(): allow more slop, |
29 | and retry up to three times, sleeping a random nap between |
30 | the retries |
31 | - human months are one-based (noticed by Anton Berezin) |
32 | |
82cbdcc3 |
33 | 1.82 [2005-10-06] |
34 | - CLOCK_REALTIME is an enum value (of the clockid_t enum) |
35 | in HP-UX (and might be so elsewhere, too), debugged by |
36 | H. Merijn Brand |
37 | - include const-c.inc as late as possible (from Randy Kobes, |
38 | [rt.cpan.org #15552] to avoid undefined usleep() on Win32 |
39 | |
a5929ff3 |
40 | 1.81 [2005-11-05] |
b311af62 |
41 | - try to be more robust and consistent in the detection of |
42 | CLOCK_REALTIME and ITIMER_VIRTUAL in HiRes.t: the proper |
43 | way is |
44 | |
45 | sub has_symbol { |
46 | my $symbol = shift; |
47 | eval 'import Time::HiRes qw($symbol)'; |
48 | return 0 unless $@ eq ''; |
49 | return exists ${"Time::HiRes::$symbol"}; |
50 | } |
51 | |
52 | and then use |
53 | |
54 | &FOO_BAR |
55 | |
56 | in the test. All these moves are needed because |
57 | |
58 | 1) one cannot directly do eval 'Time::HiRes::FOO_BAR' |
59 | because FOO_BAR might have a true value of zero |
60 | (or in the general case an empty string or even undef) |
61 | |
62 | 2) In case FOO_BAR is not available in this platform, |
63 | &FOO_BAR avoids the bareword warning |
64 | |
65 | - wait more (1.5 seconds instead of 0.1) for the CLOCK_REALTIME test |
66 | but expect the 'customary' slop of 0.20 instead of 0.25 |
67 | - fixed inside a comment HAS_POLL -> TIME_HIRES_NANOSLEEP |
68 | - at the end of HiRest.t tell how close we were to termination |
69 | |
a5929ff3 |
70 | 1.80 [2005-11-04] |
70cf0185 |
71 | - Gisle noticed a mistake (using HAS_NANOSLEEP) in 1.79 |
72 | |
a5929ff3 |
73 | 1.79 [2005-11-03] |
e5433ad8 |
74 | - try nanosleep for emulating usleep -- may help in some weird |
75 | embedded realtime places which have nanosleep but neither usleep |
76 | nor select nor poll (doesn't have to be weird embedded realtime |
77 | place, though -- in many places usleep is nanosleep anyway) |
78 | - try poll for emulating usleep -- this may help some obscure/old |
79 | SVR4 places that have neither usleep nor select |
80 | - a redundant test guard in HiRes.t |
81 | |
a5929ff3 |
82 | 1.78 [2005-11-03] |
1a7d3a53 |
83 | - ITIMER_VIRTUAL detection in HiRes.t had problems (that we cannot |
e5433ad8 |
84 | in the general case fail already at 'use' phase is suboptimal) |
1a7d3a53 |
85 | - fixes to the documentation of clock_gettime() and clock_getres() |
86 | |
a5929ff3 |
87 | 1.77 [2005-11-03] |
ced84e60 |
88 | - add support for the POSIX clock_gettime() and clock_getres(), |
89 | if available, either as library calls or as syscalls |
90 | - be more defensive about missing functionality: break out |
91 | early (during 'use') if no e.g. clock_getres() is available, |
92 | and protect our back by trapping those cases also in HiRes.xs |
93 | - the test added in 1.76 could cause an endless loop e.g. in Solaris, |
94 | due to mixing of sleep() and alarm() (bad programmer, no cookie!) |
95 | |
3d0346a5 |
96 | 1.76 [2005-10-22] |
97 | - testing for nanosleep had wrong logic which caused nanosleep |
98 | to become undefined for e.g. Mac OS X |
99 | - added a test for a core dump that was introduced by Perl 5.8.0 |
100 | safe signals and was fixed for the time of 5.8.1 (one report of |
101 | the core dump was [perl #20920]), the test skipped pre-5.8.1. |
102 | - *cough* s/unanosleep/nanosleep/g; *cough* |
103 | |
9649b81b |
104 | 1.75 [2005-10-18] |
105 | - installation patch from Gisle Aas: in Perls 5.8.x and later |
106 | use MakeMaker INSTALLDIRS value of 'perl' instead of 'site'. |
107 | |
06252d99 |
108 | 1.74 [2005-09-19] |
109 | - [cpan #14608] Solaris 8 perl 5.005_03 File::Spec module does not have method rel2abs |
110 | (the workaround is not to use rel2abs, should not be necessary) |
111 | - [cpan #14642] U2time wrongly exported on the C API |
112 | (patch supplied by the reporter, SALVA@cpan.org) |
113 | - add release dates to Changes |
114 | |
115 | 1.73 [2005-08-16] |
116 | - Time::HiRes::nanosleep support for Solaris [PATCH] |
937b804e |
117 | (POSIX::uname() not available if building with core perl, |
118 | from Gisle Aas, via perl5-porters, perl change #25295) |
119 | |
06252d99 |
120 | 1.72 [2005-07-01] |
121 | - going back to the 1.68 loader setup (using DynaLoader) |
0cf8ddea |
122 | since too many weird things starting breaking |
123 | - fix a typo in José Auguste-Etienne's name |
124 | |
06252d99 |
125 | 1.71 [2005-06-28] |
126 | - a thinko in the nanosleep() detection |
56c1b3bd |
127 | - move more changes stuff from the README to Changes |
128 | - add -w to the Makefile.PL |
129 | |
06252d99 |
130 | 1.70 [2005-06-26] |
131 | - oops in 1.69 about @ISA (not affecting anything but silly) |
f8daf111 |
132 | - add copyright 2005 to HiRes.pm |
133 | - add copyright and license to HiRes.xs |
56c1b3bd |
134 | - add copyrights 2003, 2004, 2005 to README |
f8daf111 |
135 | |
06252d99 |
136 | 1.69 [2005-06-25] |
137 | - actually run a test for nanosleep |
56c1b3bd |
138 | (if there is no $Config{d_nanosleep}) since e.g. in AIX 4.2 |
26e22fd9 |
139 | it seems that one can link in nanosleep() but then calling |
140 | it fails instantly and sets errno to ENOSYS (Not implemented). |
141 | This may be fixable in the AIX case by figuring out the right |
142 | (realtime POSIX?) libs and whatnot, but in the general case |
143 | running a real test case is better. (Of course, this change |
144 | will no doubt run into portability problems because of the |
0cf8ddea |
145 | execution step...) Note that because of hysterical raisins |
146 | most Perls do NOT have $Config{d_nanosleep} (scanning for |
147 | it by Configure would in many platforms require linking in |
148 | things like -lrt, which would in many platforms be a bad idea |
149 | for Perl itself). |
150 | (from José Auguste-Etienne) |
26e22fd9 |
151 | - support XSLoader also since it's much faster |
152 | (from Alexey Tourbin) |
153 | - add SEE ALSO (BSD::Resource and Time::TAI64) |
154 | |
06252d99 |
155 | 1.68 [2005-05-14] |
993164ab |
156 | - somehow 1.67 had a lot of doubled lines (a major cut-and-paste |
157 | error suspected), but miraculously it still worked since the |
158 | doubling took place below the __END__ token |
159 | - undef Pause() before defining it to avoid redefinition warnings |
160 | during compilation in case perl.h had already defined Pause() |
161 | (part of perl change #24271) |
162 | - minor doc tweaks |
163 | |
06252d99 |
164 | 1.67 [2005-05-04] |
993164ab |
165 | - (internal) don't ignore the return value of gettimeofday() |
166 | - (external) return undef or an empty if the C gettimeofday() fails |
167 | (affects Time::HiRes gettimeofday() and the hires time()) |
168 | |
06252d99 |
169 | 1.66 [2004-12-19] |
44d3ce20 |
170 | - add nanosleep() |
171 | - fix the 'hierachy' typo in Makefile.PL [rt.cpan.org #8492] |
172 | - should now build in Solaris [rt.cpan.org #7165] (since 1.64) |
173 | - should now build in Cygwin [rt.cpan.org #7535] (since 1.64) |
82cbdcc3 |
174 | - close also [rt.cpan.org #5933] "Time::HiRes::time does not |
175 | pick up time adjustments like ntp" since ever reproducing it |
176 | (and therefore verifying a possible fix) in the same environment |
44d3ce20 |
177 | has become rather unlikely |
178 | |
06252d99 |
179 | 1.65 [2004-09-18] |
64a7a97c |
180 | - one should not mix u?alarm and sleep (the tests modified |
181 | by 1.65, #12 and #13, hung in Solaris), now we just busy |
182 | loop executing an empty block |
183 | - in the documentation underline the unspecificity of mixing |
184 | sleeps and alarms |
185 | - small spelling fixes |
186 | |
06252d99 |
187 | 1.64 [2004-09-16] |
64a7a97c |
188 | - regenerate ppport.h with Devel::PPPort 3.03, |
189 | now the MY_CXT_CLONE is defined in ppport.h, |
190 | we no more need to do that. |
191 | |
192 | - the test #12 would often hang in sigsuspend() (at least that's |
193 | where Mac OS X' ktrace shows it hanging). With the sleep()s |
194 | changed to sleep(1)s, the tests still pass but no hang after |
195 | a few hundred repeats. |
196 | |
06252d99 |
197 | 1.63 [2004-09-01] |
1fbb4de4 |
198 | - Win32 and any ithread build: ppport.h didn't define |
170c5524 |
199 | MY_CXT_CLONE, which seems to be a Time-HiRes-ism. |
1fbb4de4 |
200 | |
06252d99 |
201 | 1.62 [2004-08-31] |
1fbb4de4 |
202 | - Skip testing if under PERL_CORE and Time::HiRes has not |
203 | been Configured (from Marcus Holland-Moritz, core change |
204 | #23246) |
205 | - Use ppport.h generated by Devel::PPPort 3.01, |
206 | allowing cutting away our own portability code. |
207 | - Don't use $ENV{PERL_CORE} for < 5.6.0. |
208 | - Don't use "for my $i" for <= 5.003. |
209 | - Don't use Pause() for <= 5.003. |
210 | - Can't use newSVpvf for <= 5.003. |
211 | (most of the changes from Marcus) |
212 | |
06252d99 |
213 | 1.61 [2004-08-21] |
4ed0e2d4 |
214 | - Win32: reset reading from the performance counters every |
215 | five minutes to better track wall clock time (thanks to |
216 | PC timers being often quite bad), should help long-running |
217 | programs. |
218 | |
06252d99 |
219 | 1.60 [2004-08-15] |
4ed0e2d4 |
220 | - Win32: Patch from Steve Hay |
221 | [PATCH] Re: [perl #30755] [Win32] Different results from Time::HiRes::gettimeofdayunder the debugger |
222 | to [perl #30755] reported by Nigel Sandever |
223 | |
224 | - Cygwin: Use the Win32 recalibration code also in Cygwin if the |
225 | <w32api/windows.h> APIs are available. Cygwin testing by |
226 | Yitzchak Scott-Thoennes. |
227 | |
228 | - Solaris: use -lposix4 to get nanosleep for Solaris 2.6, |
229 | after that keep using -lrt, patch from Alan Burlison, |
230 | bug reported in [cpan #7165] |
231 | |
06252d99 |
232 | 1.59 [2004-04-08] |
d8cb5b61 |
233 | - Change the Win32 recalibration limit to 0.5 seconds and tweak |
234 | the documentation to blather less about the gory details of the |
235 | Win32 implementation and more about the complications in general |
236 | of meddling with the system clock. |
237 | |
06252d99 |
238 | 1.58 [2004-04-08] |
d8cb5b61 |
239 | - Document the 1.57 change better. |
240 | |
06252d99 |
241 | 1.57 [2004-07-04] |
d8cb5b61 |
242 | - Win32/Cygwin/MinGW: if the performance counter drifts by more |
243 | than two seconds from the system clock (due to ntp adjustments, |
c1dc6e7c |
244 | for example), recalibrate our internal counter: from Jan Dubois, |
245 | based on [cpan #5933] by Jerry D. Hedden. |
246 | |
06252d99 |
247 | 1.56 [2004-29-02] |
1caec985 |
248 | - Give a clearer message if the tests timeout (perl change #22253) |
249 | - Don't use /tmp or its moral equivalents (perl bug #15036, |
250 | perl change #22258) |
251 | |
06252d99 |
252 | 1.55 [2004-01-14] |
4ed0e2d4 |
253 | - Windows: mingw32 patch from Mike Pomraning (use Perl's Const64() |
b6136f41 |
254 | instead of VC-specific i64 suffix) |
255 | |
06252d99 |
256 | 1.54 [2003-12-31] |
0225372c |
257 | - Solaris: like Tru64 (dec_osf) also Solaris need -lrt for nanosleep |
258 | |
06252d99 |
259 | 1.53 [2003-12-30] |
0225372c |
260 | - Windows: higher resolution time() by using the Windows |
261 | performance counter API, from Jan Dubois and Anton Shcherbinin. |
262 | The exact new higher resolution depends on the hardware, |
263 | but it should be quite a bit better than using the basic |
264 | Windows timers. |
265 | |
06252d99 |
266 | 1.52 [2003-10-28] |
690f7c5f |
267 | - In AIX (v?) with perl 5.6.1 the HiRes.t can hang after |
268 | the subtest 18. No known analysis nor fix, but added |
269 | an alarm (that requires fork() and alarm()) to the test. |
270 | |
06252d99 |
271 | 1.51 [2003-09-22] |
b85af263 |
272 | - doc tweaks from mjd (perl change #20456) |
273 | - NCR MP-RAS hints file added (svr4.pl) (perl change #21249) |
274 | |
06252d99 |
275 | 1.50 [2003-08-02] |
d7358e6a |
276 | - add a message (for non-core builds) to Makefile.PL about |
277 | the LC_ALL=C workaround |
278 | - &Time::HiRes::d_nanosleep was broken (perl change #20131) |
279 | - the nanosleep() probe was broken (perl change #20061) |
280 | - use existence instead of definedness for feature probes |
281 | (perl change #20043) |
282 | - MPE/iX tweak (perl change #20042) |
283 | - do not use HAS_NANOSLEEP (perl change #19898) |
284 | |
06252d99 |
285 | 1.49 [2003-06-23] |
df16a331 |
286 | - UVuf for non-IVSIZE platforms (from Keiichiro Nagano) |
287 | - OS/2 can always mix subsecond sleeps with signals |
288 | (part of perl change #19789) |
289 | |
06252d99 |
290 | 1.48 [2003-06-04] |
2d9815af |
291 | - workaround for buggy gcc 2.95.3 in openbsd/sparc64 |
292 | (perl change #19592) |
293 | |
06252d99 |
294 | 1.47 [2003-05-03] |
2d9815af |
295 | - do not use -lrt in Linux (from March Lehmann, perl change #19449) |
1a08a6ab |
296 | - unnecessary (nanosleep is in libc anyway) |
297 | - harmful (-lrt slows down execution) |
298 | - incompatible (with many distributions' pthreads) |
299 | |
06252d99 |
300 | 1.46 [2003-04-25] |
25ca0970 |
301 | - do not create files in blib directories under core |
302 | (perl change #19160, from rgs) |
303 | - detypo s/VTLARM/VTARLM/ (perl change #19328, from mjd) |
304 | |
06252d99 |
305 | 1.45 [2003-04-01] |
25ca0970 |
306 | - guarantee that $xdefine in HiRes.t is always defined |
307 | (perl change #19109, from IlyaZ) |
308 | - a cleaner way to detect PERL_CORE (perl change #19111, |
309 | from IlyaZ) |
310 | |
06252d99 |
311 | 1.44 [2003-03-30] |
0be47ac6 |
312 | - add hints/irix.pl to turn off overly POSIX flags that |
313 | cause hide struct timespec to be hidden (and compilation |
25ca0970 |
314 | to fail) (bleadperl change #19085) |
0be47ac6 |
315 | - documentation tweaks |
316 | |
06252d99 |
317 | 1.43 [2003-03-11] |
a0c8e3cf |
318 | - add c:/temp to the list of temp directories to probe |
319 | so that cygwin (and win*?) builds are happy. This was |
320 | needed at least in my cygwin 1.3.20/w2k setup. |
321 | |
06252d99 |
322 | 1.42 [2003-01-07] |
98b50af3 |
323 | - modernize the constants code (from Nicholas Clark) |
324 | |
06252d99 |
325 | 1.41 [2003-01-03] |
98b50af3 |
326 | - At some point the ability to figure our the correct incdir |
327 | for EXTERN.h (either a core perl build, or an installed perl) |
328 | had broken (which lead into all test compiles failing with |
329 | a core perl build, but thanks to the robustness of Makefile.PL |
a0c8e3cf |
330 | nothing of this was visible). The brokenness seemed to be |
331 | caused by $ENV{PERL_CORE} not being on for core builds? |
332 | Now stole a trick from the Encode that sets $ENV{PERL_CORE} |
333 | right, and both styles of build should work again. |
98b50af3 |
334 | |
06252d99 |
335 | 1.40 [2003-01-03] |
98b50af3 |
336 | - Nicholas Clark noticed that the my_catdir() emulation function |
337 | was broken (which means that we didn't really work for Perls |
338 | 5.002 and 5.003) |
339 | - inspired by fixing the above made the whole Makefile.PL -w |
340 | and strict clean |
341 | - tightened up the Makefile.PL output, less whitespace |
342 | |
06252d99 |
343 | 1.39 [2003-10-20] |
6a20eacc |
344 | - fix from Craig Berry for better building in VMS with PERL_CORE |
345 | |
06252d99 |
346 | 1.38 [2003-10-13] |
3f2ee006 |
347 | - no functional changes |
348 | - move lib/Time/HiRes.pm as Hires.pm |
349 | - libraries scanning was slightly broken (always scanned |
350 | for a library even when $Config{libs} already had it) |
351 | |
06252d99 |
352 | 1.37 [2003-09-23] |
3f2ee006 |
353 | - Ray Zimmerman ran into a race condition in Mac OS X. |
354 | A 0.01-second alarm fired before the test expected. |
355 | The test first slept indefinitely (blocking for signals) |
356 | and only after that tested for the signal having been sent. |
357 | Since the signal had already been sent, the test #12 never |
358 | completed. The solution: test first, then block. |
359 | - default to being silent on all probing attempts, set the |
360 | environment variable VERBOSE to a true value to see the |
361 | details (the probing command and the possible errors) |
362 | |

363 | 1.36 [2003-09-12] |
3f2ee006 |
364 | - do not clear MAN3PODS in Makefile.PL (Radoslaw Zielinski) |
365 | - INSTALLDIRS => 'perl' missing which means that Time::HiRes |
366 | cannot be upgraded from CPAN to override the 5.8.0 version |
367 | (Guido A. Ostkamp) |
368 | - Time::HiRes 1.35 could not be dropped as-is to bleadperl |
369 | because the include directories did not adjust themselves |
370 | if $ENV{PERL_CORE} (Hugo van der Sanden) |
371 | - add documentation about the restart of select() under alarm() |
372 | |
06252d99 |
373 | 1.35 [2003-08-24] |
3f2ee006 |
374 | - small documentation tweaks |
375 | |
376 | |
06252d99 |
377 | 1.34 [2003-08-22] |
3f2ee006 |
378 | - better VMS operation (Craig Berry) |
379 | |
06252d99 |
380 | 1.33 [2003-08-20] |
3f2ee006 |
381 | - our time machine is accelerating: now works with Perl 5.004_01 |
382 | (tried with 5.003_07 and 5.002 but I get segmentation faults |
383 | from running the Makefile.PL with those in Tru64 4.0D) |
384 | |
06252d99 |
385 | 1.32 [2003-08-20] |
3f2ee006 |
386 | - backward compatibility (pre-5.6.0) tweaks: |
387 | - no XSLoader in 5.00503, use DynaLoader instead |
388 | - no SvPV_nolen, either |
389 | - no PerlProc_pause(), either |
390 | - now tested with 5.00404 and 5.00503 |
391 | - Makefile.PL requires 5.00404 (no more 5.002) |
392 | - use nanosleep instead of usleep, if it is available (Wilson Snyder) |
393 | (this means that one can mix subsecond sleeps with alarms) |
394 | - because of nanosleep we probe for -lrt and -lposix4 |
395 | - the existence of getitimer/nanosleep/setitimer/ualarm/usleep |
396 | is available by exportable constants Time::HiRes::d_func |
397 | (since older Perl do not have them in %Config, and even |
398 | 5.8.0 does not probe for nanosleep) |
399 | |
06252d99 |
400 | 1.31 [2003-08-19] |
3f2ee006 |
401 | - backward compatibility (pre-5.6.1) tweaks: |
402 | - define NV if no NVTYPE |
403 | - define IVdf if needed (note: the Devel::PPPort |
404 | in 5.8.0 does not try hard hard enough since |
405 | the IVSIZE might not be defined) |
406 | - define NVgf if needed |
407 | - grab the typemap from 5.8.0 for the NV stuff |
56c1b3bd |
408 | |
409 | 1.31 and 1.32 add more backward compatibility (now all the way |
410 | back to Perl 5.00404), and using nanosleep() (if available) for |
411 | subsecond sleeps. |
412 | |
06252d99 |
413 | 1.30 [2003-08-16] |
3f2ee006 |
414 | |
415 | - release 1.29_02 as 1.30 |
416 | |
56c1b3bd |
417 | 1.30 adds all the changes made during the Perl 5.6->5.7->5.8 |
418 | development cycle. Most notably portability across platforms has been |
419 | enhanced, and the interval timers (setitimer, getitimer) have been |
420 | added. Note that the version of Time::HiRes that is included in Perl |
421 | 5.8.0 calls itself 1.20_00, but it is equivalent to this Time::HiRes |
422 | version. Note also that in 1.30 Wegscheid turns over the maintenance |
423 | to Jarkko Hietaniemi. |
424 | |
06252d99 |
425 | 1.29_02 [2003-08-16] |
3f2ee006 |
426 | |
427 | - fix a silly unclosed comment typo in HiRes.xs |
428 | - document and export REALTIME_REALPROF (Solaris) |
429 | |
06252d99 |
430 | 1.29_01 [2003-08-16] |
3f2ee006 |
431 | |
432 | - only getitimer(ITIMER_REAL) available in Cygwin and Win32 |
433 | (need to patch this also in Perl 5.[89]) |
434 | - remove CVS revision log from HiRes.xs |
435 | |
06252d99 |
436 | 1.29_00 [2003-08-14] |

502 | |
503 | The following changes were made on top of the changes |
504 | made for Time::HiRes during the Perl 5.7 development |
505 | cycle that culminated in the release of Perl 5.8.0. |
506 | |
507 | - add "require 5.005" to the Makefile.PL |
508 | - remove the REVISION section (CVS log) from HiRes.pm |
509 | - add jhi's copyright alongside Douglas' |
510 | - move HiRes.pm to lib/Time/ |
511 | - move HiRes.t to t/ |
512 | - modify HiRes.t to use $ENV{PERL_CORE} |
513 | - modify the original Time::HiRes version 1.20 Makefile.PL |
514 | to work both with Perl 5.8.0 and the new code with pre-5.8.0 |
515 | Perls (tried with 5.6.1) |
516 | - tiny tweaks and updates in README and TODO |
517 | - bump the VERSION to 1.29 |
518 | |
dcf686c9 |
519 | 1.20 Wed Feb 24 21:30 1999 |
520 | - make our usleep and ualarm substitutes into hrt_usleep |
521 | and hrt_ualarm. This helps static links of Perl with other |
522 | packages that also have usleep, etc. From |
523 | Ilya Zakharevich <ilya@math.ohio-state.edu> |
524 | - add C API stuff. From Joshua Pritikin |
525 | <joshua.pritikin@db.com> |
3f2ee006 |
526 | - VMS Makefile.PL fun. From pvhp@forte.com (Peter Prymmer) |
dcf686c9 |
527 | - hopefully correct "-lc" fix for SCO. |
528 | - add PPD stuff |
529 | |
56c1b3bd |
530 | 1.20 adds a platform neutral set of C accessible routines if you are |
531 | running 5.005+. All other changes are packaging changes and build |
532 | fixes(?) for statically linked Perl, SCO, and VMS. |
533 | |
dcf686c9 |
534 | 1.19 Tue Sep 29 22:30 1998 |
535 | - put VMS gettimeofday() in. Patch is from Sebastian Bazley |
536 | <seb@stian.demon.co.uk> |
537 | - change GIMME_V to GIMME to help people with older versions of |
538 | Perl. |
539 | - fix Win32 version of gettimeofday(). It didn't affect anything, |
540 | but it confuses people reading the code when the return value |
541 | is backwards (0 is success). |
542 | - fix Makefile.PL (more) so that detection of gettimeofday is |
543 | more correct. |
544 | |
56c1b3bd |
545 | 1.19 has better VMS support. |
546 | |
dcf686c9 |
547 | 1.18 Mon Jul 6 22:40 1998 |
548 | - add usleep() for Win32. |
549 | - fix Makefile.PL to fix reported HP/UX feature where unresolved |
550 | externals still cause an executable to be generated (though no |
551 | x bit set). Thanks to David Kozinn for report and explanation. |
552 | Problems with the fix are mine :) |
553 | |
56c1b3bd |
554 | 1.18 has limited Win32 support (no ualarm). Added usleep for Win32. |
555 | Probably buggy. I'm sure I'll hear. |
556 | |
dcf686c9 |
557 | 1.17 Wed Jul 1 20:10 1998 |
558 | - fix setitimer calls so microseconds is not more than 1000000. |
559 | Hp/UX 9 doesn't like that. Provided by Roland B Robert, PhD. |
3f2ee006 |
560 | - make Win32. We only get gettimeofday (the select hack doesn't |
dcf686c9 |
561 | seem to work on my Win95 system). |
3f2ee006 |
562 | - fix test 4 on 01test.t. add test to see if time() and |
dcf686c9 |
563 | Time::HiRes::time() are close. |
564 | |
565 | 1.16 Wed Nov 12 21:05 1997 |
566 | - add missing EXTEND in new gettimeofday scalar code. |
567 | |
56c1b3bd |
568 | 1.16+ should be closer to building out of the box on Linux. Thanks |
569 | to Gisle Aas for patches, and the ualarm equivalent using setitimer. |
570 | |
571 | If your underlying operating system doesn't implement ualarm(), then |
572 | a fake using setitimer() will be made. If the OS is missing usleep(), |
573 | a fake one using select() will be made. If a fake can't be made for |
574 | either ualarm() or usleep(), then the corresponding Perl function will |
575 | not be available. If the OS is missing gettimeofday(), you will get |
576 | unresolved externals, either at link- or run-time. |
577 | |
578 | This is an improvement; the package used to not even build if |
579 | you were missing any of these bits. Roderick Schertler |
580 | |
581 | <roderick@argon.org> did all the conditional compilation stuff, |
582 | look at HiRes.pm and the test suites; it's good educational reading. |
583 | |
dcf686c9 |
584 | 1.15 Mon Nov 10 21:30 1997 |
585 | - HiRes.pm: update pod. Provided by Gisle Aas. |
586 | - HiRes.xs: if gettimeofday() called in scalar context, do |
587 | something more useful than before. Provided by Gisle Aas. |
588 | - README: tell of xsubpp '-nolinenumber' woes. thanks to |
589 | Edward Henigin <ed@texas.net> for pointing out the problem. |
590 | |
591 | 1.14 Wed Nov 5 9:40 1997 |
592 | - Makefile.PL: look for setitimer |
593 | - HiRes.xs: if missing ualarm, but we have setitimer, make up |
594 | our own setitimer. These were provided by Gisle Aas. |
595 | |
596 | 1.13 Tue Nov 4 23:30 1997 |
597 | - Makefile.PL: fix autodetect mechanism to do try linking in addition |
598 | to just compiling; should fix Linux build problem. Fix was provided |
599 | by Gisle Aas. |
600 | |
601 | 1.12 Sun Oct 12 12:00:00 1997 |
602 | - Makefile.PL: set XSOPT to '-nolinenumbers' to work around xsubpp bug; |
603 | you may need to comment this back out if you have an older xsubpp. |
604 | - HiRes.xs: set PROTOTYPES: DISABLE |
605 | |
606 | 1.11 Fri Sep 05 16:00:00 1997 |
607 | - Makefile.PL: |
608 | Had some line commented out that shouldn't have been (testing |
609 | remnants) |
610 | - README: |
611 | Previous version was corrupted. |
612 | |
613 | 1.10 Thu May 22 20:20:00 1997 |
614 | - HiRes.xs, HiRes.pm, t/*: |
615 | - only compile what we have OS support for (or can |
616 | fake with select()) |
617 | - only test what we compiled |
618 | - gross improvement to the test suite |
619 | - fix EXPORT_FAIL. |
620 | This work was all done by Roderick Schertler |
621 | <roderick@argon.org>. If you run Linux or |
170c5524 |
622 | one of the other ualarm-less platforms, and you like this |
dcf686c9 |
623 | module, let Roderick know; without him, it still wouldn't |
624 | be working on those boxes... |
625 | - Makefile.PL: figure out what routines the OS has and |
626 | only build what we need. These bits were written by Jarkko |
627 | Hietaniemi <jhi@iki.fi>. Again, gratitude is due... |
628 | |
629 | 1.02 Mon Dec 30 08:00:00 1996 |
630 | - HiRes.pm: update documentation to say what to do when missing |
631 | ualarm() and friends. |
632 | - README: update to warn that ualarm() and friends need to exist |
633 | |
634 | 1.01 Fri Oct 17 08:00:00 1996 |
635 | - Makefile.PL: make XSPROTOARGS => '-noprototyopes' |
636 | - HiRes.pm: put blank line between __END__ and =head1 so that |
637 | pod2man works. |
638 | |
639 | 1.00 Tue Sep 03 13:00:00 1996 |
640 | - original version; created by h2xs 1.16 |
