1 | Revision history for Perl extension Time::HiRes. |
2 | |
44d3ce20 |
3 | 1.66 |
4 | - add nanosleep() |
5 | - fix the 'hierachy' typo in Makefile.PL [rt.cpan.org #8492] |
6 | - should now build in Solaris [rt.cpan.org #7165] (since 1.64) |
7 | - should now build in Cygwin [rt.cpan.org #7535] (since 1.64) |
8 | - close also [rt.cpan.org #5933] "Time::HiRes::time does not pick up time adjustments like ntp" since ever reproducing it in the same environment |
9 | has become rather unlikely |
10 | |
64a7a97c |
11 | 1.65 |
12 | - one should not mix u?alarm and sleep (the tests modified |
13 | by 1.65, #12 and #13, hung in Solaris), now we just busy |
14 | loop executing an empty block |
15 | - in the documentation underline the unspecificity of mixing |
16 | sleeps and alarms |
17 | - small spelling fixes |
18 | |
19 | 1.64 |
20 | - regenerate ppport.h with Devel::PPPort 3.03, |
21 | now the MY_CXT_CLONE is defined in ppport.h, |
22 | we no more need to do that. |
23 | |
24 | - the test #12 would often hang in sigsuspend() (at least that's |
25 | where Mac OS X' ktrace shows it hanging). With the sleep()s |
26 | changed to sleep(1)s, the tests still pass but no hang after |
27 | a few hundred repeats. |
28 | |
1fbb4de4 |
29 | 1.63 |
30 | - Win32 and any ithread build: ppport.h didn't define |
31 | MY_CXT_CLONE, which seems to be a Time-HiResism. |
32 | |
33 | 1.62 |
34 | - Skip testing if under PERL_CORE and Time::HiRes has not |
35 | been Configured (from Marcus Holland-Moritz, core change |
36 | #23246) |
37 | - Use ppport.h generated by Devel::PPPort 3.01, |
38 | allowing cutting away our own portability code. |
39 | - Don't use $ENV{PERL_CORE} for < 5.6.0. |
40 | - Don't use "for my $i" for <= 5.003. |
41 | - Don't use Pause() for <= 5.003. |
42 | - Can't use newSVpvf for <= 5.003. |
43 | (most of the changes from Marcus) |
44 | |
4ed0e2d4 |
45 | 1.61 |
46 | - Win32: reset reading from the performance counters every |
47 | five minutes to better track wall clock time (thanks to |
48 | PC timers being often quite bad), should help long-running |
49 | programs. |
50 | |
51 | 1.60 |
52 | - Win32: Patch from Steve Hay |
53 | [PATCH] Re: [perl #30755] [Win32] Different results from Time::HiRes::gettimeofdayunder the debugger |
54 | to [perl #30755] reported by Nigel Sandever |
55 | |
56 | - Cygwin: Use the Win32 recalibration code also in Cygwin if the |
57 | <w32api/windows.h> APIs are available. Cygwin testing by |
58 | Yitzchak Scott-Thoennes. |
59 | |
60 | - Solaris: use -lposix4 to get nanosleep for Solaris 2.6, |
61 | after that keep using -lrt, patch from Alan Burlison, |
62 | bug reported in [cpan #7165] |
63 | |
d8cb5b61 |
64 | 1.59 |
65 | - Change the Win32 recalibration limit to 0.5 seconds and tweak |
66 | the documentation to blather less about the gory details of the |
67 | Win32 implementation and more about the complications in general |
68 | of meddling with the system clock. |
69 | |
70 | 1.58 |
71 | - Document the 1.57 change better. |
72 | |
c1dc6e7c |
73 | 1.57 |
d8cb5b61 |
74 | - Win32/Cygwin/MinGW: if the performance counter drifts by more |
75 | than two seconds from the system clock (due to ntp adjustments, |
c1dc6e7c |
76 | for example), recalibrate our internal counter: from Jan Dubois, |
77 | based on [cpan #5933] by Jerry D. Hedden. |
78 | |
1caec985 |
79 | 1.56 |
80 | - Give a clearer message if the tests timeout (perl change #22253) |
81 | - Don't use /tmp or its moral equivalents (perl bug #15036, |
82 | perl change #22258) |
83 | |
b6136f41 |
84 | 1.55 |
4ed0e2d4 |
85 | - Windows: mingw32 patch from Mike Pomraning (use Perl's Const64() |
b6136f41 |
86 | instead of VC-specific i64 suffix) |
87 | |
0225372c |
88 | 1.54 |
89 | - Solaris: like Tru64 (dec_osf) also Solaris need -lrt for nanosleep |
90 | |
91 | 1.53 |
92 | - Windows: higher resolution time() by using the Windows |
93 | performance counter API, from Jan Dubois and Anton Shcherbinin. |
94 | The exact new higher resolution depends on the hardware, |
95 | but it should be quite a bit better than using the basic |
96 | Windows timers. |
97 | |
690f7c5f |
98 | 1.52 |
99 | - In AIX (v?) with perl 5.6.1 the HiRes.t can hang after |
100 | the subtest 18. No known analysis nor fix, but added |
101 | an alarm (that requires fork() and alarm()) to the test. |
102 | |
b85af263 |
103 | 1.51 |
104 | - doc tweaks from mjd (perl change #20456) |
105 | - NCR MP-RAS hints file added (svr4.pl) (perl change #21249) |
106 | |
d7358e6a |
107 | 1.50 |
108 | - add a message (for non-core builds) to Makefile.PL about |
109 | the LC_ALL=C workaround |
110 | - &Time::HiRes::d_nanosleep was broken (perl change #20131) |
111 | - the nanosleep() probe was broken (perl change #20061) |
112 | - use existence instead of definedness for feature probes |
113 | (perl change #20043) |
114 | - MPE/iX tweak (perl change #20042) |
115 | - do not use HAS_NANOSLEEP (perl change #19898) |
116 | |
df16a331 |
117 | 1.49 |
118 | - UVuf for non-IVSIZE platforms (from Keiichiro Nagano) |
119 | - OS/2 can always mix subsecond sleeps with signals |
120 | (part of perl change #19789) |
121 | |
2d9815af |
122 | 1.48 |
123 | - workaround for buggy gcc 2.95.3 in openbsd/sparc64 |
124 | (perl change #19592) |
125 | |
1a08a6ab |
126 | 1.47 |
2d9815af |
127 | - do not use -lrt in Linux (from March Lehmann, perl change #19449) |
1a08a6ab |
128 | - unnecessary (nanosleep is in libc anyway) |
129 | - harmful (-lrt slows down execution) |
130 | - incompatible (with many distributions' pthreads) |
131 | |
25ca0970 |
132 | 1.46 |
133 | - do not create files in blib directories under core |
134 | (perl change #19160, from rgs) |
135 | - detypo s/VTLARM/VTARLM/ (perl change #19328, from mjd) |
136 | |
137 | 1.45 |
138 | - guarantee that $xdefine in HiRes.t is always defined |
139 | (perl change #19109, from IlyaZ) |
140 | - a cleaner way to detect PERL_CORE (perl change #19111, |
141 | from IlyaZ) |
142 | |
0be47ac6 |
143 | 1.44 |
144 | - add hints/irix.pl to turn off overly POSIX flags that |
145 | cause hide struct timespec to be hidden (and compilation |
25ca0970 |
146 | to fail) (bleadperl change #19085) |
0be47ac6 |
147 | - documentation tweaks |
148 | |
a0c8e3cf |
149 | 1.43 |
150 | - add c:/temp to the list of temp directories to probe |
151 | so that cygwin (and win*?) builds are happy. This was |
152 | needed at least in my cygwin 1.3.20/w2k setup. |
153 | |
98b50af3 |
154 | 1.42 |
155 | - modernize the constants code (from Nicholas Clark) |
156 | |
157 | 1.41 |
158 | - At some point the ability to figure our the correct incdir |
159 | for EXTERN.h (either a core perl build, or an installed perl) |
160 | had broken (which lead into all test compiles failing with |
161 | a core perl build, but thanks to the robustness of Makefile.PL |
a0c8e3cf |
162 | nothing of this was visible). The brokenness seemed to be |
163 | caused by $ENV{PERL_CORE} not being on for core builds? |
164 | Now stole a trick from the Encode that sets $ENV{PERL_CORE} |
165 | right, and both styles of build should work again. |
98b50af3 |
166 | |
167 | 1.40 |
168 | - Nicholas Clark noticed that the my_catdir() emulation function |
169 | was broken (which means that we didn't really work for Perls |
170 | 5.002 and 5.003) |
171 | - inspired by fixing the above made the whole Makefile.PL -w |
172 | and strict clean |
173 | - tightened up the Makefile.PL output, less whitespace |
174 | |
6a20eacc |
175 | 1.39 |
176 | - fix from Craig Berry for better building in VMS with PERL_CORE |
177 | |
3f2ee006 |
178 | 1.38 |
179 | - no functional changes |
180 | - move lib/Time/HiRes.pm as Hires.pm |
181 | - libraries scanning was slightly broken (always scanned |
182 | for a library even when $Config{libs} already had it) |
183 | |
184 | 1.37 |
185 | - Ray Zimmerman ran into a race condition in Mac OS X. |
186 | A 0.01-second alarm fired before the test expected. |
187 | The test first slept indefinitely (blocking for signals) |
188 | and only after that tested for the signal having been sent. |
189 | Since the signal had already been sent, the test #12 never |
190 | completed. The solution: test first, then block. |
191 | - default to being silent on all probing attempts, set the |
192 | environment variable VERBOSE to a true value to see the |
193 | details (the probing command and the possible errors) |
194 | |
195 | 1.36 |
196 | - do not clear MAN3PODS in Makefile.PL (Radoslaw Zielinski) |
197 | - INSTALLDIRS => 'perl' missing which means that Time::HiRes |
198 | cannot be upgraded from CPAN to override the 5.8.0 version |
199 | (Guido A. Ostkamp) |
200 | - Time::HiRes 1.35 could not be dropped as-is to bleadperl |
201 | because the include directories did not adjust themselves |
202 | if $ENV{PERL_CORE} (Hugo van der Sanden) |
203 | - add documentation about the restart of select() under alarm() |
204 | |
205 | 1.35 |
206 | - small documentation tweaks |
207 | |
208 | |
209 | 1.34 |
210 | - better VMS operation (Craig Berry) |
211 | |
212 | 1.33 |
213 | - our time machine is accelerating: now works with Perl 5.004_01 |
214 | (tried with 5.003_07 and 5.002 but I get segmentation faults |
215 | from running the Makefile.PL with those in Tru64 4.0D) |
216 | |
217 | 1.32 |
218 | - backward compatibility (pre-5.6.0) tweaks: |
219 | - no XSLoader in 5.00503, use DynaLoader instead |
220 | - no SvPV_nolen, either |
221 | - no PerlProc_pause(), either |
222 | - now tested with 5.00404 and 5.00503 |
223 | - Makefile.PL requires 5.00404 (no more 5.002) |
224 | - use nanosleep instead of usleep, if it is available (Wilson Snyder) |
225 | (this means that one can mix subsecond sleeps with alarms) |
226 | - because of nanosleep we probe for -lrt and -lposix4 |
227 | - the existence of getitimer/nanosleep/setitimer/ualarm/usleep |
228 | is available by exportable constants Time::HiRes::d_func |
229 | (since older Perl do not have them in %Config, and even |
230 | 5.8.0 does not probe for nanosleep) |
231 | |
232 | 1.31 |
233 | - backward compatibility (pre-5.6.1) tweaks: |
234 | - define NV if no NVTYPE |
235 | - define IVdf if needed (note: the Devel::PPPort |
236 | in 5.8.0 does not try hard hard enough since |
237 | the IVSIZE might not be defined) |
238 | - define NVgf if needed |
239 | - grab the typemap from 5.8.0 for the NV stuff |
240 | 1.30 |
241 | |
242 | - release 1.29_02 as 1.30 |
243 | |
244 | 1.29_02 |
245 | |
246 | - fix a silly unclosed comment typo in HiRes.xs |
247 | - document and export REALTIME_REALPROF (Solaris) |
248 | |
249 | 1.29_01 |
250 | |
251 | - only getitimer(ITIMER_REAL) available in Cygwin and Win32 |
252 | (need to patch this also in Perl 5.[89]) |
253 | - remove CVS revision log from HiRes.xs |
254 | |
255 | 1.29_00 |
256 | |

322 | The following changes were made on top of the changes |
323 | made for Time::HiRes during the Perl 5.7 development |
324 | cycle that culminated in the release of Perl 5.8.0. |
325 | |
326 | - add "require 5.005" to the Makefile.PL |
327 | - remove the REVISION section (CVS log) from HiRes.pm |
328 | - add jhi's copyright alongside Douglas' |
329 | - move HiRes.pm to lib/Time/ |
330 | - move HiRes.t to t/ |
331 | - modify HiRes.t to use $ENV{PERL_CORE} |
332 | - modify the original Time::HiRes version 1.20 Makefile.PL |
333 | to work both with Perl 5.8.0 and the new code with pre-5.8.0 |
334 | Perls (tried with 5.6.1) |
335 | - tiny tweaks and updates in README and TODO |
336 | - bump the VERSION to 1.29 |
337 | |
dcf686c9 |
338 | 1.20 Wed Feb 24 21:30 1999 |
339 | - make our usleep and ualarm substitutes into hrt_usleep |
340 | and hrt_ualarm. This helps static links of Perl with other |
341 | packages that also have usleep, etc. From |
342 | Ilya Zakharevich <ilya@math.ohio-state.edu> |
343 | - add C API stuff. From Joshua Pritikin |
344 | <joshua.pritikin@db.com> |
3f2ee006 |
345 | - VMS Makefile.PL fun. From pvhp@forte.com (Peter Prymmer) |
dcf686c9 |
346 | - hopefully correct "-lc" fix for SCO. |
347 | - add PPD stuff |
348 | |
349 | 1.19 Tue Sep 29 22:30 1998 |
350 | - put VMS gettimeofday() in. Patch is from Sebastian Bazley |
351 | <seb@stian.demon.co.uk> |
352 | - change GIMME_V to GIMME to help people with older versions of |
353 | Perl. |
354 | - fix Win32 version of gettimeofday(). It didn't affect anything, |
355 | but it confuses people reading the code when the return value |
356 | is backwards (0 is success). |
357 | - fix Makefile.PL (more) so that detection of gettimeofday is |
358 | more correct. |
359 | |
360 | 1.18 Mon Jul 6 22:40 1998 |
361 | - add usleep() for Win32. |
362 | - fix Makefile.PL to fix reported HP/UX feature where unresolved |
363 | externals still cause an executable to be generated (though no |
364 | x bit set). Thanks to David Kozinn for report and explanation. |
365 | Problems with the fix are mine :) |
366 | |
367 | 1.17 Wed Jul 1 20:10 1998 |
368 | - fix setitimer calls so microseconds is not more than 1000000. |
369 | Hp/UX 9 doesn't like that. Provided by Roland B Robert, PhD. |
3f2ee006 |
370 | - make Win32. We only get gettimeofday (the select hack doesn't |
dcf686c9 |
371 | seem to work on my Win95 system). |
3f2ee006 |
372 | - fix test 4 on 01test.t. add test to see if time() and |
dcf686c9 |
373 | Time::HiRes::time() are close. |
374 | |
375 | 1.16 Wed Nov 12 21:05 1997 |
376 | - add missing EXTEND in new gettimeofday scalar code. |
377 | |
378 | 1.15 Mon Nov 10 21:30 1997 |
379 | - HiRes.pm: update pod. Provided by Gisle Aas. |
380 | - HiRes.xs: if gettimeofday() called in scalar context, do |
381 | something more useful than before. Provided by Gisle Aas. |
382 | - README: tell of xsubpp '-nolinenumber' woes. thanks to |
383 | Edward Henigin <ed@texas.net> for pointing out the problem. |
384 | |
385 | 1.14 Wed Nov 5 9:40 1997 |
386 | - Makefile.PL: look for setitimer |
387 | - HiRes.xs: if missing ualarm, but we have setitimer, make up |
388 | our own setitimer. These were provided by Gisle Aas. |
389 | |
390 | 1.13 Tue Nov 4 23:30 1997 |
391 | - Makefile.PL: fix autodetect mechanism to do try linking in addition |
392 | to just compiling; should fix Linux build problem. Fix was provided |
393 | by Gisle Aas. |
394 | |

396 | - Makefile.PL: set XSOPT to '-nolinenumbers' to work around xsubpp bug; |
397 | you may need to comment this back out if you have an older xsubpp. |
398 | - HiRes.xs: set PROTOTYPES: DISABLE |
399 | |
400 | 1.11 Fri Sep 05 16:00:00 1997 |
401 | - Makefile.PL: |
402 | Had some line commented out that shouldn't have been (testing |
403 | remnants) |
404 | - README: |
405 | Previous version was corrupted. |
406 | |
407 | 1.10 Thu May 22 20:20:00 1997 |
408 | - HiRes.xs, HiRes.pm, t/*: |
409 | - only compile what we have OS support for (or can |
410 | fake with select()) |
411 | - only test what we compiled |
412 | - gross improvement to the test suite |
413 | - fix EXPORT_FAIL. |
414 | This work was all done by Roderick Schertler |
415 | <roderick@argon.org>. If you run Linux or |
416 | one of the other ualarm-less platoforms, and you like this |
417 | module, let Roderick know; without him, it still wouldn't |
418 | be working on those boxes... |
419 | - Makefile.PL: figure out what routines the OS has and |
420 | only build what we need. These bits were written by Jarkko |
421 | Hietaniemi <jhi@iki.fi>. Again, gratitude is due... |
422 | |
423 | 1.02 Mon Dec 30 08:00:00 1996 |
424 | - HiRes.pm: update documentation to say what to do when missing |
425 | ualarm() and friends. |
426 | - README: update to warn that ualarm() and friends need to exist |
427 | |
428 | 1.01 Fri Oct 17 08:00:00 1996 |
429 | - Makefile.PL: make XSPROTOARGS => '-noprototyopes' |
430 | - HiRes.pm: put blank line between __END__ and =head1 so that |
431 | pod2man works. |
