1 | Revision history for Perl extension Time::HiRes. |
2 | |
26e22fd9 |
3 | 1.69 - actually run a test for nanosleep since e.g. in AIX 4.2 |
4 | it seems that one can link in nanosleep() but then calling |
5 | it fails instantly and sets errno to ENOSYS (Not implemented). |
6 | This may be fixable in the AIX case by figuring out the right |
7 | (realtime POSIX?) libs and whatnot, but in the general case |
8 | running a real test case is better. (Of course, this change |
9 | will no doubt run into portability problems because of the |
10 | execution step...) |
11 | (from José Auguste-tienne) |
12 | - support XSLoader also since it's much faster |
13 | (from Alexey Tourbin) |
14 | - add SEE ALSO (BSD::Resource and Time::TAI64) |
15 | |
993164ab |
16 | 1.68 |
17 | - somehow 1.67 had a lot of doubled lines (a major cut-and-paste |
18 | error suspected), but miraculously it still worked since the |
19 | doubling took place below the __END__ token |
20 | - undef Pause() before defining it to avoid redefinition warnings |
21 | during compilation in case perl.h had already defined Pause() |
22 | (part of perl change #24271) |
23 | - minor doc tweaks |
24 | |
25 | 1.67 |
26 | - (internal) don't ignore the return value of gettimeofday() |
27 | - (external) return undef or an empty if the C gettimeofday() fails |
28 | (affects Time::HiRes gettimeofday() and the hires time()) |
29 | |
44d3ce20 |
30 | 1.66 |
31 | - add nanosleep() |
32 | - fix the 'hierachy' typo in Makefile.PL [rt.cpan.org #8492] |
33 | - should now build in Solaris [rt.cpan.org #7165] (since 1.64) |
34 | - should now build in Cygwin [rt.cpan.org #7535] (since 1.64) |
35 | - 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 |
36 | has become rather unlikely |
37 | |
64a7a97c |
38 | 1.65 |
39 | - one should not mix u?alarm and sleep (the tests modified |
40 | by 1.65, #12 and #13, hung in Solaris), now we just busy |
41 | loop executing an empty block |
42 | - in the documentation underline the unspecificity of mixing |
43 | sleeps and alarms |
44 | - small spelling fixes |
45 | |
46 | 1.64 |
47 | - regenerate ppport.h with Devel::PPPort 3.03, |
48 | now the MY_CXT_CLONE is defined in ppport.h, |
49 | we no more need to do that. |
50 | |
51 | - the test #12 would often hang in sigsuspend() (at least that's |
52 | where Mac OS X' ktrace shows it hanging). With the sleep()s |
53 | changed to sleep(1)s, the tests still pass but no hang after |
54 | a few hundred repeats. |
55 | |
1fbb4de4 |
56 | 1.63 |
57 | - Win32 and any ithread build: ppport.h didn't define |
58 | MY_CXT_CLONE, which seems to be a Time-HiResism. |
59 | |
60 | 1.62 |
61 | - Skip testing if under PERL_CORE and Time::HiRes has not |
62 | been Configured (from Marcus Holland-Moritz, core change |
63 | #23246) |
64 | - Use ppport.h generated by Devel::PPPort 3.01, |
65 | allowing cutting away our own portability code. |
66 | - Don't use $ENV{PERL_CORE} for < 5.6.0. |
67 | - Don't use "for my $i" for <= 5.003. |
68 | - Don't use Pause() for <= 5.003. |
69 | - Can't use newSVpvf for <= 5.003. |
70 | (most of the changes from Marcus) |
71 | |
4ed0e2d4 |
72 | 1.61 |
73 | - Win32: reset reading from the performance counters every |
74 | five minutes to better track wall clock time (thanks to |
75 | PC timers being often quite bad), should help long-running |
76 | programs. |
77 | |
78 | 1.60 |
79 | - Win32: Patch from Steve Hay |
80 | [PATCH] Re: [perl #30755] [Win32] Different results from Time::HiRes::gettimeofdayunder the debugger |
81 | to [perl #30755] reported by Nigel Sandever |
82 | |
83 | - Cygwin: Use the Win32 recalibration code also in Cygwin if the |
84 | <w32api/windows.h> APIs are available. Cygwin testing by |
85 | Yitzchak Scott-Thoennes. |
86 | |
87 | - Solaris: use -lposix4 to get nanosleep for Solaris 2.6, |
88 | after that keep using -lrt, patch from Alan Burlison, |
89 | bug reported in [cpan #7165] |
90 | |
d8cb5b61 |
91 | 1.59 |
92 | - Change the Win32 recalibration limit to 0.5 seconds and tweak |
93 | the documentation to blather less about the gory details of the |
94 | Win32 implementation and more about the complications in general |
95 | of meddling with the system clock. |
96 | |
97 | 1.58 |
98 | - Document the 1.57 change better. |
99 | |
c1dc6e7c |
100 | 1.57 |
d8cb5b61 |
101 | - Win32/Cygwin/MinGW: if the performance counter drifts by more |
102 | than two seconds from the system clock (due to ntp adjustments, |
c1dc6e7c |
103 | for example), recalibrate our internal counter: from Jan Dubois, |
104 | based on [cpan #5933] by Jerry D. Hedden. |
105 | |
1caec985 |
106 | 1.56 |
107 | - Give a clearer message if the tests timeout (perl change #22253) |
108 | - Don't use /tmp or its moral equivalents (perl bug #15036, |
109 | perl change #22258) |
110 | |
b6136f41 |
111 | 1.55 |
4ed0e2d4 |
112 | - Windows: mingw32 patch from Mike Pomraning (use Perl's Const64() |
b6136f41 |
113 | instead of VC-specific i64 suffix) |
114 | |
0225372c |
115 | 1.54 |
116 | - Solaris: like Tru64 (dec_osf) also Solaris need -lrt for nanosleep |
117 | |
118 | 1.53 |
119 | - Windows: higher resolution time() by using the Windows |
120 | performance counter API, from Jan Dubois and Anton Shcherbinin. |
121 | The exact new higher resolution depends on the hardware, |
122 | but it should be quite a bit better than using the basic |
123 | Windows timers. |
124 | |
690f7c5f |
125 | 1.52 |
126 | - In AIX (v?) with perl 5.6.1 the HiRes.t can hang after |
127 | the subtest 18. No known analysis nor fix, but added |
128 | an alarm (that requires fork() and alarm()) to the test. |
129 | |
b85af263 |
130 | 1.51 |
131 | - doc tweaks from mjd (perl change #20456) |
132 | - NCR MP-RAS hints file added (svr4.pl) (perl change #21249) |
133 | |
d7358e6a |
134 | 1.50 |
135 | - add a message (for non-core builds) to Makefile.PL about |
136 | the LC_ALL=C workaround |
137 | - &Time::HiRes::d_nanosleep was broken (perl change #20131) |
138 | - the nanosleep() probe was broken (perl change #20061) |
139 | - use existence instead of definedness for feature probes |
140 | (perl change #20043) |
141 | - MPE/iX tweak (perl change #20042) |
142 | - do not use HAS_NANOSLEEP (perl change #19898) |
143 | |
df16a331 |
144 | 1.49 |
145 | - UVuf for non-IVSIZE platforms (from Keiichiro Nagano) |
146 | - OS/2 can always mix subsecond sleeps with signals |
147 | (part of perl change #19789) |
148 | |
2d9815af |
149 | 1.48 |
150 | - workaround for buggy gcc 2.95.3 in openbsd/sparc64 |
151 | (perl change #19592) |
152 | |
1a08a6ab |
153 | 1.47 |
2d9815af |
154 | - do not use -lrt in Linux (from March Lehmann, perl change #19449) |
1a08a6ab |
155 | - unnecessary (nanosleep is in libc anyway) |
156 | - harmful (-lrt slows down execution) |
157 | - incompatible (with many distributions' pthreads) |
158 | |
25ca0970 |
159 | 1.46 |
160 | - do not create files in blib directories under core |
161 | (perl change #19160, from rgs) |
162 | - detypo s/VTLARM/VTARLM/ (perl change #19328, from mjd) |
163 | |
164 | 1.45 |
165 | - guarantee that $xdefine in HiRes.t is always defined |
166 | (perl change #19109, from IlyaZ) |
167 | - a cleaner way to detect PERL_CORE (perl change #19111, |
168 | from IlyaZ) |
169 | |
0be47ac6 |
170 | 1.44 |
171 | - add hints/irix.pl to turn off overly POSIX flags that |
172 | cause hide struct timespec to be hidden (and compilation |
25ca0970 |
173 | to fail) (bleadperl change #19085) |
0be47ac6 |
174 | - documentation tweaks |
175 | |
a0c8e3cf |
176 | 1.43 |
177 | - add c:/temp to the list of temp directories to probe |
178 | so that cygwin (and win*?) builds are happy. This was |
179 | needed at least in my cygwin 1.3.20/w2k setup. |
180 | |
98b50af3 |
181 | 1.42 |
182 | - modernize the constants code (from Nicholas Clark) |
183 | |
184 | 1.41 |
185 | - At some point the ability to figure our the correct incdir |
186 | for EXTERN.h (either a core perl build, or an installed perl) |
187 | had broken (which lead into all test compiles failing with |
188 | a core perl build, but thanks to the robustness of Makefile.PL |
a0c8e3cf |
189 | nothing of this was visible). The brokenness seemed to be |
190 | caused by $ENV{PERL_CORE} not being on for core builds? |
191 | Now stole a trick from the Encode that sets $ENV{PERL_CORE} |
192 | right, and both styles of build should work again. |
98b50af3 |
193 | |
194 | 1.40 |
195 | - Nicholas Clark noticed that the my_catdir() emulation function |
196 | was broken (which means that we didn't really work for Perls |
197 | 5.002 and 5.003) |
198 | - inspired by fixing the above made the whole Makefile.PL -w |
199 | and strict clean |
200 | - tightened up the Makefile.PL output, less whitespace |
201 | |
6a20eacc |
202 | 1.39 |
203 | - fix from Craig Berry for better building in VMS with PERL_CORE |
204 | |
3f2ee006 |
205 | 1.38 |
206 | - no functional changes |
207 | - move lib/Time/HiRes.pm as Hires.pm |
208 | - libraries scanning was slightly broken (always scanned |
209 | for a library even when $Config{libs} already had it) |
210 | |
211 | 1.37 |
212 | - Ray Zimmerman ran into a race condition in Mac OS X. |
213 | A 0.01-second alarm fired before the test expected. |
214 | The test first slept indefinitely (blocking for signals) |
215 | and only after that tested for the signal having been sent. |
216 | Since the signal had already been sent, the test #12 never |
217 | completed. The solution: test first, then block. |
218 | - default to being silent on all probing attempts, set the |
219 | environment variable VERBOSE to a true value to see the |
220 | details (the probing command and the possible errors) |
221 | |
222 | 1.36 |
223 | - do not clear MAN3PODS in Makefile.PL (Radoslaw Zielinski) |
224 | - INSTALLDIRS => 'perl' missing which means that Time::HiRes |
225 | cannot be upgraded from CPAN to override the 5.8.0 version |
226 | (Guido A. Ostkamp) |
227 | - Time::HiRes 1.35 could not be dropped as-is to bleadperl |
228 | because the include directories did not adjust themselves |
229 | if $ENV{PERL_CORE} (Hugo van der Sanden) |
230 | - add documentation about the restart of select() under alarm() |
231 | |
232 | 1.35 |
233 | - small documentation tweaks |
234 | |
235 | |
236 | 1.34 |
237 | - better VMS operation (Craig Berry) |
238 | |
239 | 1.33 |
240 | - our time machine is accelerating: now works with Perl 5.004_01 |
241 | (tried with 5.003_07 and 5.002 but I get segmentation faults |
242 | from running the Makefile.PL with those in Tru64 4.0D) |
243 | |
244 | 1.32 |
245 | - backward compatibility (pre-5.6.0) tweaks: |
246 | - no XSLoader in 5.00503, use DynaLoader instead |
247 | - no SvPV_nolen, either |
248 | - no PerlProc_pause(), either |
249 | - now tested with 5.00404 and 5.00503 |
250 | - Makefile.PL requires 5.00404 (no more 5.002) |
251 | - use nanosleep instead of usleep, if it is available (Wilson Snyder) |
252 | (this means that one can mix subsecond sleeps with alarms) |
253 | - because of nanosleep we probe for -lrt and -lposix4 |
254 | - the existence of getitimer/nanosleep/setitimer/ualarm/usleep |
255 | is available by exportable constants Time::HiRes::d_func |
256 | (since older Perl do not have them in %Config, and even |
257 | 5.8.0 does not probe for nanosleep) |
258 | |
259 | 1.31 |
260 | - backward compatibility (pre-5.6.1) tweaks: |
261 | - define NV if no NVTYPE |
262 | - define IVdf if needed (note: the Devel::PPPort |
263 | in 5.8.0 does not try hard hard enough since |
264 | the IVSIZE might not be defined) |
265 | - define NVgf if needed |
266 | - grab the typemap from 5.8.0 for the NV stuff |
267 | 1.30 |
268 | |
269 | - release 1.29_02 as 1.30 |
270 | |
271 | 1.29_02 |
272 | |
273 | - fix a silly unclosed comment typo in HiRes.xs |
274 | - document and export REALTIME_REALPROF (Solaris) |
275 | |
276 | 1.29_01 |
277 | |
278 | - only getitimer(ITIMER_REAL) available in Cygwin and Win32 |
279 | (need to patch this also in Perl 5.[89]) |
280 | - remove CVS revision log from HiRes.xs |
281 | |
282 | 1.29_00 |
283 | |

348 | |
349 | The following changes were made on top of the changes |
350 | made for Time::HiRes during the Perl 5.7 development |
351 | cycle that culminated in the release of Perl 5.8.0. |
352 | |
353 | - add "require 5.005" to the Makefile.PL |
354 | - remove the REVISION section (CVS log) from HiRes.pm |
355 | - add jhi's copyright alongside Douglas' |
356 | - move HiRes.pm to lib/Time/ |
357 | - move HiRes.t to t/ |
358 | - modify HiRes.t to use $ENV{PERL_CORE} |
359 | - modify the original Time::HiRes version 1.20 Makefile.PL |
360 | to work both with Perl 5.8.0 and the new code with pre-5.8.0 |
361 | Perls (tried with 5.6.1) |
362 | - tiny tweaks and updates in README and TODO |
363 | - bump the VERSION to 1.29 |
364 | |
dcf686c9 |
365 | 1.20 Wed Feb 24 21:30 1999 |
366 | - make our usleep and ualarm substitutes into hrt_usleep |
367 | and hrt_ualarm. This helps static links of Perl with other |
368 | packages that also have usleep, etc. From |
369 | Ilya Zakharevich <ilya@math.ohio-state.edu> |
370 | - add C API stuff. From Joshua Pritikin |
371 | <joshua.pritikin@db.com> |
3f2ee006 |
372 | - VMS Makefile.PL fun. From pvhp@forte.com (Peter Prymmer) |
dcf686c9 |
373 | - hopefully correct "-lc" fix for SCO. |
374 | - add PPD stuff |
375 | |
376 | 1.19 Tue Sep 29 22:30 1998 |
377 | - put VMS gettimeofday() in. Patch is from Sebastian Bazley |
378 | <seb@stian.demon.co.uk> |
379 | - change GIMME_V to GIMME to help people with older versions of |
380 | Perl. |
381 | - fix Win32 version of gettimeofday(). It didn't affect anything, |
382 | but it confuses people reading the code when the return value |
383 | is backwards (0 is success). |
384 | - fix Makefile.PL (more) so that detection of gettimeofday is |
385 | more correct. |
386 | |
387 | 1.18 Mon Jul 6 22:40 1998 |
388 | - add usleep() for Win32. |
389 | - fix Makefile.PL to fix reported HP/UX feature where unresolved |
390 | externals still cause an executable to be generated (though no |
391 | x bit set). Thanks to David Kozinn for report and explanation. |
392 | Problems with the fix are mine :) |
393 | |
394 | 1.17 Wed Jul 1 20:10 1998 |
395 | - fix setitimer calls so microseconds is not more than 1000000. |
396 | Hp/UX 9 doesn't like that. Provided by Roland B Robert, PhD. |
3f2ee006 |
397 | - make Win32. We only get gettimeofday (the select hack doesn't |
dcf686c9 |

441 | This work was all done by Roderick Schertler |
442 | <roderick@argon.org>. If you run Linux or |
443 | one of the other ualarm-less platoforms, and you like this |
444 | module, let Roderick know; without him, it still wouldn't |
445 | be working on those boxes... |
446 | - Makefile.PL: figure out what routines the OS has and |
447 | only build what we need. These bits were written by Jarkko |
448 | Hietaniemi <jhi@iki.fi>. Again, gratitude is due... |
