1 | Revision history for Perl extension Time::HiRes. |
2 | |
a5929ff3 |
3 | 1.83 [2005-11-19] |
4 | - has_symbol() was wrong since e.g. ITIMER_VIRTUAL is exported |
5 | via @EXPORT_OK even when it is not available. This is heinous. |
6 | @EXPORT_OK should be determined at Makefile.PL time. |
7 | - be more lenient is testing clock_gettime(): allow more slop, |
8 | and retry up to three times, sleeping a random nap between |
9 | the retries |
10 | - human months are one-based (noticed by Anton Berezin) |
11 | |
82cbdcc3 |
12 | 1.82 [2005-10-06] |
13 | - CLOCK_REALTIME is an enum value (of the clockid_t enum) |
14 | in HP-UX (and might be so elsewhere, too), debugged by |
15 | H. Merijn Brand |
16 | - include const-c.inc as late as possible (from Randy Kobes, |
17 | [rt.cpan.org #15552] to avoid undefined usleep() on Win32 |
18 | |
a5929ff3 |
19 | 1.81 [2005-11-05] |
b311af62 |
20 | - try to be more robust and consistent in the detection of |
21 | CLOCK_REALTIME and ITIMER_VIRTUAL in HiRes.t: the proper |
22 | way is |
23 | |
24 | sub has_symbol { |
25 | my $symbol = shift; |
26 | eval 'import Time::HiRes qw($symbol)'; |
27 | return 0 unless $@ eq ''; |
28 | return exists ${"Time::HiRes::$symbol"}; |
29 | } |
30 | |
31 | and then use |
32 | |
33 | &FOO_BAR |
34 | |
35 | in the test. All these moves are needed because |
36 | |
37 | 1) one cannot directly do eval 'Time::HiRes::FOO_BAR' |
38 | because FOO_BAR might have a true value of zero |
39 | (or in the general case an empty string or even undef) |
40 | |
41 | 2) In case FOO_BAR is not available in this platform, |
42 | &FOO_BAR avoids the bareword warning |
43 | |
44 | - wait more (1.5 seconds instead of 0.1) for the CLOCK_REALTIME test |
45 | but expect the 'customary' slop of 0.20 instead of 0.25 |
46 | - fixed inside a comment HAS_POLL -> TIME_HIRES_NANOSLEEP |
47 | - at the end of HiRest.t tell how close we were to termination |
48 | |
a5929ff3 |
49 | 1.80 [2005-11-04] |
70cf0185 |
50 | - Gisle noticed a mistake (using HAS_NANOSLEEP) in 1.79 |
51 | |
a5929ff3 |
52 | 1.79 [2005-11-03] |
e5433ad8 |
53 | - try nanosleep for emulating usleep -- may help in some weird |
54 | embedded realtime places which have nanosleep but neither usleep |
55 | nor select nor poll (doesn't have to be weird embedded realtime |
56 | place, though -- in many places usleep is nanosleep anyway) |
57 | - try poll for emulating usleep -- this may help some obscure/old |
58 | SVR4 places that have neither usleep nor select |
59 | - a redundant test guard in HiRes.t |
60 | |
a5929ff3 |
61 | 1.78 [2005-11-03] |
1a7d3a53 |
62 | - ITIMER_VIRTUAL detection in HiRes.t had problems (that we cannot |
e5433ad8 |
63 | in the general case fail already at 'use' phase is suboptimal) |
1a7d3a53 |
64 | - fixes to the documentation of clock_gettime() and clock_getres() |
65 | |
a5929ff3 |
66 | 1.77 [2005-11-03] |
ced84e60 |
67 | - add support for the POSIX clock_gettime() and clock_getres(), |
68 | if available, either as library calls or as syscalls |
69 | - be more defensive about missing functionality: break out |
70 | early (during 'use') if no e.g. clock_getres() is available, |
71 | and protect our back by trapping those cases also in HiRes.xs |
72 | - the test added in 1.76 could cause an endless loop e.g. in Solaris, |
73 | due to mixing of sleep() and alarm() (bad programmer, no cookie!) |
74 | |
3d0346a5 |
75 | 1.76 [2005-10-22] |
76 | - testing for nanosleep had wrong logic which caused nanosleep |
77 | to become undefined for e.g. Mac OS X |
78 | - added a test for a core dump that was introduced by Perl 5.8.0 |
79 | safe signals and was fixed for the time of 5.8.1 (one report of |
80 | the core dump was [perl #20920]), the test skipped pre-5.8.1. |
81 | - *cough* s/unanosleep/nanosleep/g; *cough* |
82 | |
9649b81b |
83 | 1.75 [2005-10-18] |
84 | - installation patch from Gisle Aas: in Perls 5.8.x and later |
85 | use MakeMaker INSTALLDIRS value of 'perl' instead of 'site'. |
86 | |
06252d99 |
87 | 1.74 [2005-09-19] |
88 | - [cpan #14608] Solaris 8 perl 5.005_03 File::Spec module does not have method rel2abs |
89 | (the workaround is not to use rel2abs, should not be necessary) |
90 | - [cpan #14642] U2time wrongly exported on the C API |
91 | (patch supplied by the reporter, SALVA@cpan.org) |
92 | - add release dates to Changes |
93 | |
94 | 1.73 [2005-08-16] |
95 | - Time::HiRes::nanosleep support for Solaris [PATCH] |
937b804e |
96 | (POSIX::uname() not available if building with core perl, |
97 | from Gisle Aas, via perl5-porters, perl change #25295) |
98 | |
06252d99 |
99 | 1.72 [2005-07-01] |
100 | - going back to the 1.68 loader setup (using DynaLoader) |
0cf8ddea |
101 | since too many weird things starting breaking |
102 | - fix a typo in José Auguste-Etienne's name |
103 | |
06252d99 |
104 | 1.71 [2005-06-28] |
105 | - a thinko in the nanosleep() detection |
56c1b3bd |
106 | - move more changes stuff from the README to Changes |
107 | - add -w to the Makefile.PL |
108 | |
06252d99 |
109 | 1.70 [2005-06-26] |
110 | - oops in 1.69 about @ISA (not affecting anything but silly) |
f8daf111 |
111 | - add copyright 2005 to HiRes.pm |
112 | - add copyright and license to HiRes.xs |
56c1b3bd |
113 | - add copyrights 2003, 2004, 2005 to README |
f8daf111 |
114 | |
06252d99 |
115 | 1.69 [2005-06-25] |
116 | - actually run a test for nanosleep |
56c1b3bd |
117 | (if there is no $Config{d_nanosleep}) since e.g. in AIX 4.2 |
26e22fd9 |
118 | it seems that one can link in nanosleep() but then calling |
119 | it fails instantly and sets errno to ENOSYS (Not implemented). |
120 | This may be fixable in the AIX case by figuring out the right |
121 | (realtime POSIX?) libs and whatnot, but in the general case |
122 | running a real test case is better. (Of course, this change |
123 | will no doubt run into portability problems because of the |
0cf8ddea |
124 | execution step...) Note that because of hysterical raisins |
125 | most Perls do NOT have $Config{d_nanosleep} (scanning for |
126 | it by Configure would in many platforms require linking in |
127 | things like -lrt, which would in many platforms be a bad idea |
128 | for Perl itself). |
129 | (from José Auguste-Etienne) |
26e22fd9 |
130 | - support XSLoader also since it's much faster |
131 | (from Alexey Tourbin) |
132 | - add SEE ALSO (BSD::Resource and Time::TAI64) |
133 | |
06252d99 |
134 | 1.68 [2005-05-14] |
993164ab |
135 | - somehow 1.67 had a lot of doubled lines (a major cut-and-paste |
136 | error suspected), but miraculously it still worked since the |
137 | doubling took place below the __END__ token |
138 | - undef Pause() before defining it to avoid redefinition warnings |
139 | during compilation in case perl.h had already defined Pause() |
140 | (part of perl change #24271) |
141 | - minor doc tweaks |
142 | |
06252d99 |
143 | 1.67 [2005-05-04] |
993164ab |
144 | - (internal) don't ignore the return value of gettimeofday() |
145 | - (external) return undef or an empty if the C gettimeofday() fails |
146 | (affects Time::HiRes gettimeofday() and the hires time()) |
147 | |
06252d99 |
148 | 1.66 [2004-12-19] |
44d3ce20 |
149 | - add nanosleep() |
150 | - fix the 'hierachy' typo in Makefile.PL [rt.cpan.org #8492] |
151 | - should now build in Solaris [rt.cpan.org #7165] (since 1.64) |
152 | - should now build in Cygwin [rt.cpan.org #7535] (since 1.64) |
82cbdcc3 |
153 | - close also [rt.cpan.org #5933] "Time::HiRes::time does not |
154 | pick up time adjustments like ntp" since ever reproducing it |
155 | (and therefore verifying a possible fix) in the same environment |
44d3ce20 |
156 | has become rather unlikely |
157 | |
06252d99 |
158 | 1.65 [2004-09-18] |
64a7a97c |
159 | - one should not mix u?alarm and sleep (the tests modified |
160 | by 1.65, #12 and #13, hung in Solaris), now we just busy |
161 | loop executing an empty block |
162 | - in the documentation underline the unspecificity of mixing |
163 | sleeps and alarms |
164 | - small spelling fixes |
165 | |
06252d99 |
166 | 1.64 [2004-09-16] |
64a7a97c |
167 | - regenerate ppport.h with Devel::PPPort 3.03, |
168 | now the MY_CXT_CLONE is defined in ppport.h, |
169 | we no more need to do that. |
170 | |
171 | - the test #12 would often hang in sigsuspend() (at least that's |
172 | where Mac OS X' ktrace shows it hanging). With the sleep()s |
173 | changed to sleep(1)s, the tests still pass but no hang after |
174 | a few hundred repeats. |
175 | |
06252d99 |
176 | 1.63 [2004-09-01] |
1fbb4de4 |
177 | - Win32 and any ithread build: ppport.h didn't define |
178 | MY_CXT_CLONE, which seems to be a Time-HiResism. |
179 | |
06252d99 |
180 | 1.62 [2004-08-31] |
1fbb4de4 |
181 | - Skip testing if under PERL_CORE and Time::HiRes has not |
182 | been Configured (from Marcus Holland-Moritz, core change |
183 | #23246) |
184 | - Use ppport.h generated by Devel::PPPort 3.01, |
185 | allowing cutting away our own portability code. |
186 | - Don't use $ENV{PERL_CORE} for < 5.6.0. |
187 | - Don't use "for my $i" for <= 5.003. |
188 | - Don't use Pause() for <= 5.003. |
189 | - Can't use newSVpvf for <= 5.003. |
190 | (most of the changes from Marcus) |
191 | |
06252d99 |
192 | 1.61 [2004-08-21] |
4ed0e2d4 |
193 | - Win32: reset reading from the performance counters every |
194 | five minutes to better track wall clock time (thanks to |
195 | PC timers being often quite bad), should help long-running |
196 | programs. |
197 | |
06252d99 |
198 | 1.60 [2004-08-15] |
4ed0e2d4 |
199 | - Win32: Patch from Steve Hay |
200 | [PATCH] Re: [perl #30755] [Win32] Different results from Time::HiRes::gettimeofdayunder the debugger |
201 | to [perl #30755] reported by Nigel Sandever |
202 | |
203 | - Cygwin: Use the Win32 recalibration code also in Cygwin if the |
204 | <w32api/windows.h> APIs are available. Cygwin testing by |
205 | Yitzchak Scott-Thoennes. |
206 | |
207 | - Solaris: use -lposix4 to get nanosleep for Solaris 2.6, |
208 | after that keep using -lrt, patch from Alan Burlison, |
209 | bug reported in [cpan #7165] |
210 | |
06252d99 |
211 | 1.59 [2004-04-08] |
d8cb5b61 |
212 | - Change the Win32 recalibration limit to 0.5 seconds and tweak |
213 | the documentation to blather less about the gory details of the |
214 | Win32 implementation and more about the complications in general |
215 | of meddling with the system clock. |
216 | |
06252d99 |
217 | 1.58 [2004-04-08] |
d8cb5b61 |
218 | - Document the 1.57 change better. |
219 | |
06252d99 |
220 | 1.57 [2004-07-04] |
d8cb5b61 |
221 | - Win32/Cygwin/MinGW: if the performance counter drifts by more |
222 | than two seconds from the system clock (due to ntp adjustments, |
c1dc6e7c |
223 | for example), recalibrate our internal counter: from Jan Dubois, |
224 | based on [cpan #5933] by Jerry D. Hedden. |
225 | |
06252d99 |
226 | 1.56 [2004-29-02] |
1caec985 |
227 | - Give a clearer message if the tests timeout (perl change #22253) |
228 | - Don't use /tmp or its moral equivalents (perl bug #15036, |
229 | perl change #22258) |
230 | |
06252d99 |
231 | 1.55 [2004-01-14] |
4ed0e2d4 |
232 | - Windows: mingw32 patch from Mike Pomraning (use Perl's Const64() |
b6136f41 |
233 | instead of VC-specific i64 suffix) |
234 | |
06252d99 |
235 | 1.54 [2003-12-31] |
0225372c |
236 | - Solaris: like Tru64 (dec_osf) also Solaris need -lrt for nanosleep |
237 | |
06252d99 |
238 | 1.53 [2003-12-30] |
0225372c |
239 | - Windows: higher resolution time() by using the Windows |
240 | performance counter API, from Jan Dubois and Anton Shcherbinin. |
241 | The exact new higher resolution depends on the hardware, |
242 | but it should be quite a bit better than using the basic |
243 | Windows timers. |
244 | |
06252d99 |
245 | 1.52 [2003-10-28] |
690f7c5f |
246 | - In AIX (v?) with perl 5.6.1 the HiRes.t can hang after |
247 | the subtest 18. No known analysis nor fix, but added |
248 | an alarm (that requires fork() and alarm()) to the test. |
249 | |
06252d99 |
250 | 1.51 [2003-09-22] |
b85af263 |
251 | - doc tweaks from mjd (perl change #20456) |
252 | - NCR MP-RAS hints file added (svr4.pl) (perl change #21249) |
253 | |
06252d99 |
254 | 1.50 [2003-08-02] |
d7358e6a |
255 | - add a message (for non-core builds) to Makefile.PL about |
256 | the LC_ALL=C workaround |
257 | - &Time::HiRes::d_nanosleep was broken (perl change #20131) |
258 | - the nanosleep() probe was broken (perl change #20061) |
259 | - use existence instead of definedness for feature probes |
260 | (perl change #20043) |
261 | - MPE/iX tweak (perl change #20042) |
262 | - do not use HAS_NANOSLEEP (perl change #19898) |
263 | |
06252d99 |
264 | 1.49 [2003-06-23] |
df16a331 |
265 | - UVuf for non-IVSIZE platforms (from Keiichiro Nagano) |
266 | - OS/2 can always mix subsecond sleeps with signals |
267 | (part of perl change #19789) |
268 | |
06252d99 |
269 | 1.48 [2003-06-04] |
2d9815af |
270 | - workaround for buggy gcc 2.95.3 in openbsd/sparc64 |
271 | (perl change #19592) |
272 | |
06252d99 |
273 | 1.47 [2003-05-03] |
2d9815af |
274 | - do not use -lrt in Linux (from March Lehmann, perl change #19449) |
1a08a6ab |
275 | - unnecessary (nanosleep is in libc anyway) |
276 | - harmful (-lrt slows down execution) |
277 | - incompatible (with many distributions' pthreads) |
278 | |
06252d99 |
279 | 1.46 [2003-04-25] |
25ca0970 |
280 | - do not create files in blib directories under core |
281 | (perl change #19160, from rgs) |
282 | - detypo s/VTLARM/VTARLM/ (perl change #19328, from mjd) |
283 | |
06252d99 |
284 | 1.45 [2003-04-01] |
25ca0970 |
285 | - guarantee that $xdefine in HiRes.t is always defined |
286 | (perl change #19109, from IlyaZ) |
287 | - a cleaner way to detect PERL_CORE (perl change #19111, |
288 | from IlyaZ) |
289 | |
06252d99 |
290 | 1.44 [2003-03-30] |
0be47ac6 |
291 | - add hints/irix.pl to turn off overly POSIX flags that |
292 | cause hide struct timespec to be hidden (and compilation |
25ca0970 |
293 | to fail) (bleadperl change #19085) |
0be47ac6 |
294 | - documentation tweaks |
295 | |
06252d99 |
296 | 1.43 [2003-03-11] |
a0c8e3cf |
297 | - add c:/temp to the list of temp directories to probe |
298 | so that cygwin (and win*?) builds are happy. This was |
299 | needed at least in my cygwin 1.3.20/w2k setup. |
300 | |
06252d99 |
301 | 1.42 [2003-01-07] |
98b50af3 |
302 | - modernize the constants code (from Nicholas Clark) |
303 | |
06252d99 |
304 | 1.41 [2003-01-03] |
98b50af3 |
305 | - At some point the ability to figure our the correct incdir |
306 | for EXTERN.h (either a core perl build, or an installed perl) |
307 | had broken (which lead into all test compiles failing with |
308 | a core perl build, but thanks to the robustness of Makefile.PL |
a0c8e3cf |
309 | nothing of this was visible). The brokenness seemed to be |
310 | caused by $ENV{PERL_CORE} not being on for core builds? |
311 | Now stole a trick from the Encode that sets $ENV{PERL_CORE} |
312 | right, and both styles of build should work again. |
98b50af3 |
313 | |
06252d99 |
314 | 1.40 [2003-01-03] |
98b50af3 |
315 | - Nicholas Clark noticed that the my_catdir() emulation function |
316 | was broken (which means that we didn't really work for Perls |
317 | 5.002 and 5.003) |
318 | - inspired by fixing the above made the whole Makefile.PL -w |
319 | and strict clean |
320 | - tightened up the Makefile.PL output, less whitespace |
321 | |
06252d99 |
322 | 1.39 [2003-10-20] |
6a20eacc |
323 | - fix from Craig Berry for better building in VMS with PERL_CORE |
324 | |
06252d99 |
325 | 1.38 [2003-10-13] |
3f2ee006 |
326 | - no functional changes |
327 | - move lib/Time/HiRes.pm as Hires.pm |
328 | - libraries scanning was slightly broken (always scanned |
329 | for a library even when $Config{libs} already had it) |
330 | |
06252d99 |
331 | 1.37 [2003-09-23] |
3f2ee006 |
332 | - Ray Zimmerman ran into a race condition in Mac OS X. |
333 | A 0.01-second alarm fired before the test expected. |
334 | The test first slept indefinitely (blocking for signals) |
335 | and only after that tested for the signal having been sent. |
336 | Since the signal had already been sent, the test #12 never |
337 | completed. The solution: test first, then block. |
338 | - default to being silent on all probing attempts, set the |
339 | environment variable VERBOSE to a true value to see the |
340 | details (the probing command and the possible errors) |
341 | |
06252d99 |
342 | 1.36 [2003-09-12] |
3f2ee006 |
343 | - do not clear MAN3PODS in Makefile.PL (Radoslaw Zielinski) |
344 | - INSTALLDIRS => 'perl' missing which means that Time::HiRes |
345 | cannot be upgraded from CPAN to override the 5.8.0 version |
346 | (Guido A. Ostkamp) |
347 | - Time::HiRes 1.35 could not be dropped as-is to bleadperl |
348 | because the include directories did not adjust themselves |
349 | if $ENV{PERL_CORE} (Hugo van der Sanden) |
350 | - add documentation about the restart of select() under alarm() |
351 | |
06252d99 |
352 | 1.35 [2003-08-24] |
3f2ee006 |
353 | - small documentation tweaks |
354 | |

356 | 1.34 [2003-08-22] |
3f2ee006 |
357 | - better VMS operation (Craig Berry) |
358 | |
06252d99 |
359 | 1.33 [2003-08-20] |
3f2ee006 |
360 | - our time machine is accelerating: now works with Perl 5.004_01 |
361 | (tried with 5.003_07 and 5.002 but I get segmentation faults |
362 | from running the Makefile.PL with those in Tru64 4.0D) |
363 | |
06252d99 |
364 | 1.32 [2003-08-20] |
3f2ee006 |
365 | - backward compatibility (pre-5.6.0) tweaks: |
366 | - no XSLoader in 5.00503, use DynaLoader instead |
367 | - no SvPV_nolen, either |
368 | - no PerlProc_pause(), either |
369 | - now tested with 5.00404 and 5.00503 |
370 | - Makefile.PL requires 5.00404 (no more 5.002) |
371 | - use nanosleep instead of usleep, if it is available (Wilson Snyder) |
372 | (this means that one can mix subsecond sleeps with alarms) |
373 | - because of nanosleep we probe for -lrt and -lposix4 |
374 | - the existence of getitimer/nanosleep/setitimer/ualarm/usleep |
375 | is available by exportable constants Time::HiRes::d_func |
376 | (since older Perl do not have them in %Config, and even |
377 | 5.8.0 does not probe for nanosleep) |
378 | |
06252d99 |
379 | 1.31 [2003-08-19] |
3f2ee006 |
380 | - backward compatibility (pre-5.6.1) tweaks: |
381 | - define NV if no NVTYPE |
382 | - define IVdf if needed (note: the Devel::PPPort |
383 | in 5.8.0 does not try hard hard enough since |
384 | the IVSIZE might not be defined) |
385 | - define NVgf if needed |
386 | - grab the typemap from 5.8.0 for the NV stuff |
56c1b3bd |
387 | |
388 | 1.31 and 1.32 add more backward compatibility (now all the way |
389 | back to Perl 5.00404), and using nanosleep() (if available) for |
390 | subsecond sleeps. |
391 | |
06252d99 |
392 | 1.30 [2003-08-16] |
3f2ee006 |
393 | |
394 | - release 1.29_02 as 1.30 |
395 | |
56c1b3bd |
396 | 1.30 adds all the changes made during the Perl 5.6->5.7->5.8 |
397 | development cycle. Most notably portability across platforms has been |
398 | enhanced, and the interval timers (setitimer, getitimer) have been |
399 | added. Note that the version of Time::HiRes that is included in Perl |
400 | 5.8.0 calls itself 1.20_00, but it is equivalent to this Time::HiRes |
401 | version. Note also that in 1.30 Wegscheid turns over the maintenance |
402 | to Jarkko Hietaniemi. |
403 | |
06252d99 |
404 | 1.29_02 [2003-08-16] |
3f2ee006 |
405 | |
406 | - fix a silly unclosed comment typo in HiRes.xs |
407 | - document and export REALTIME_REALPROF (Solaris) |
408 | |
06252d99 |
409 | 1.29_01 [2003-08-16] |
3f2ee006 |
410 | |
411 | - only getitimer(ITIMER_REAL) available in Cygwin and Win32 |
412 | (need to patch this also in Perl 5.[89]) |
413 | - remove CVS revision log from HiRes.xs |
414 | |
06252d99 |
415 | 1.29_00 [2003-08-14] |

481 | |
482 | The following changes were made on top of the changes |
483 | made for Time::HiRes during the Perl 5.7 development |
484 | cycle that culminated in the release of Perl 5.8.0. |
485 | |
486 | - add "require 5.005" to the Makefile.PL |
487 | - remove the REVISION section (CVS log) from HiRes.pm |
488 | - add jhi's copyright alongside Douglas' |
489 | - move HiRes.pm to lib/Time/ |
490 | - move HiRes.t to t/ |
491 | - modify HiRes.t to use $ENV{PERL_CORE} |
492 | - modify the original Time::HiRes version 1.20 Makefile.PL |
493 | to work both with Perl 5.8.0 and the new code with pre-5.8.0 |
494 | Perls (tried with 5.6.1) |
495 | - tiny tweaks and updates in README and TODO |
496 | - bump the VERSION to 1.29 |
497 | |
dcf686c9 |
498 | 1.20 Wed Feb 24 21:30 1999 |
499 | - make our usleep and ualarm substitutes into hrt_usleep |
500 | and hrt_ualarm. This helps static links of Perl with other |
501 | packages that also have usleep, etc. From |
502 | Ilya Zakharevich <ilya@math.ohio-state.edu> |
503 | - add C API stuff. From Joshua Pritikin |
504 | <joshua.pritikin@db.com> |
3f2ee006 |
505 | - VMS Makefile.PL fun. From pvhp@forte.com (Peter Prymmer) |
dcf686c9 |
506 | - hopefully correct "-lc" fix for SCO. |
507 | - add PPD stuff |
508 | |
56c1b3bd |
509 | 1.20 adds a platform neutral set of C accessible routines if you are |
510 | running 5.005+. All other changes are packaging changes and build |
511 | fixes(?) for statically linked Perl, SCO, and VMS. |
512 | |
dcf686c9 |
513 | 1.19 Tue Sep 29 22:30 1998 |
514 | - put VMS gettimeofday() in. Patch is from Sebastian Bazley |
515 | <seb@stian.demon.co.uk> |
516 | - change GIMME_V to GIMME to help people with older versions of |
517 | Perl. |
518 | - fix Win32 version of gettimeofday(). It didn't affect anything, |
519 | but it confuses people reading the code when the return value |
520 | is backwards (0 is success). |
521 | - fix Makefile.PL (more) so that detection of gettimeofday is |
522 | more correct. |
523 | |
56c1b3bd |
524 | 1.19 has better VMS support. |
525 | |
dcf686c9 |
526 | 1.18 Mon Jul 6 22:40 1998 |
527 | - add usleep() for Win32. |
528 | - fix Makefile.PL to fix reported HP/UX feature where unresolved |
529 | externals still cause an executable to be generated (though no |
530 | x bit set). Thanks to David Kozinn for report and explanation. |
531 | Problems with the fix are mine :) |
532 | |
56c1b3bd |
533 | 1.18 has limited Win32 support (no ualarm). Added usleep for Win32. |
534 | Probably buggy. I'm sure I'll hear. |
535 | |
dcf686c9 |
536 | 1.17 Wed Jul 1 20:10 1998 |
537 | - fix setitimer calls so microseconds is not more than 1000000. |
538 | Hp/UX 9 doesn't like that. Provided by Roland B Robert, PhD. |
3f2ee006 |
539 | - make Win32. We only get gettimeofday (the select hack doesn't |
dcf686c9 |
540 | seem to work on my Win95 system). |
3f2ee006 |
541 | - fix test 4 on 01test.t. add test to see if time() and |
dcf686c9 |
542 | Time::HiRes::time() are close. |
543 | |
544 | 1.16 Wed Nov 12 21:05 1997 |
545 | - add missing EXTEND in new gettimeofday scalar code. |
546 | |
56c1b3bd |
547 | 1.16+ should be closer to building out of the box on Linux. Thanks |
548 | to Gisle Aas for patches, and the ualarm equivalent using setitimer. |
549 | |
550 | If your underlying operating system doesn't implement ualarm(), then |
551 | a fake using setitimer() will be made. If the OS is missing usleep(), |
552 | a fake one using select() will be made. If a fake can't be made for |
553 | either ualarm() or usleep(), then the corresponding Perl function will |
554 | not be available. If the OS is missing gettimeofday(), you will get |
555 | unresolved externals, either at link- or run-time. |
556 | |
557 | This is an improvement; the package used to not even build if |
558 | you were missing any of these bits. Roderick Schertler |
559 | |
560 | <roderick@argon.org> did all the conditional compilation stuff, |
561 | look at HiRes.pm and the test suites; it's good educational reading. |
562 | |
dcf686c9 |
563 | 1.15 Mon Nov 10 21:30 1997 |
564 | - HiRes.pm: update pod. Provided by Gisle Aas. |
565 | - HiRes.xs: if gettimeofday() called in scalar context, do |
566 | something more useful than before. Provided by Gisle Aas. |
567 | - README: tell of xsubpp '-nolinenumber' woes. thanks to |
568 | Edward Henigin <ed@texas.net> for pointing out the problem. |
569 | |
570 | 1.14 Wed Nov 5 9:40 1997 |
571 | - Makefile.PL: look for setitimer |
572 | - HiRes.xs: if missing ualarm, but we have setitimer, make up |
573 | our own setitimer. These were provided by Gisle Aas. |
574 | |
575 | 1.13 Tue Nov 4 23:30 1997 |
576 | - Makefile.PL: fix autodetect mechanism to do try linking in addition |
577 | to just compiling; should fix Linux build problem. Fix was provided |
578 | by Gisle Aas. |
579 | |
580 | 1.12 Sun Oct 12 12:00:00 1997 |
581 | - Makefile.PL: set XSOPT to '-nolinenumbers' to work around xsubpp bug; |
582 | you may need to comment this back out if you have an older xsubpp. |
583 | - HiRes.xs: set PROTOTYPES: DISABLE |
584 | |
585 | 1.11 Fri Sep 05 16:00:00 1997 |
586 | - Makefile.PL: |
587 | Had some line commented out that shouldn't have been (testing |
588 | remnants) |
589 | - README: |
590 | Previous version was corrupted. |
591 | |
592 | 1.10 Thu May 22 20:20:00 1997 |
593 | - HiRes.xs, HiRes.pm, t/*: |
594 | - only compile what we have OS support for (or can |
595 | fake with select()) |
596 | - only test what we compiled |
597 | - gross improvement to the test suite |
598 | - fix EXPORT_FAIL. |
599 | This work was all done by Roderick Schertler |
600 | <roderick@argon.org>. If you run Linux or |
601 | one of the other ualarm-less platoforms, and you like this |
602 | module, let Roderick know; without him, it still wouldn't |
603 | be working on those boxes... |
604 | - Makefile.PL: figure out what routines the OS has and |
605 | only build what we need. These bits were written by Jarkko |
606 | Hietaniemi <jhi@iki.fi>. Again, gratitude is due... |
607 | |
608 | 1.02 Mon Dec 30 08:00:00 1996 |
609 | - HiRes.pm: update documentation to say what to do when missing |
610 | ualarm() and friends. |
611 | - README: update to warn that ualarm() and friends need to exist |
612 | |
613 | 1.01 Fri Oct 17 08:00:00 1996 |
614 | - Makefile.PL: make XSPROTOARGS => '-noprototyopes' |
615 | - HiRes.pm: put blank line between __END__ and =head1 so that |
616 | pod2man works. |
617 | |
618 | 1.00 Tue Sep 03 13:00:00 1996 |
619 | - original version; created by h2xs 1.16 |
