1 | Revision history for Perl extension Time::HiRes. |
| 2 | |
| d8cb5b61 |
3 | 1.59 |
| 4 | - Change the Win32 recalibration limit to 0.5 seconds and tweak |
| 5 | the documentation to blather less about the gory details of the |
| 6 | Win32 implementation and more about the complications in general |
| 7 | of meddling with the system clock. |
| 8 | |
| 9 | 1.58 |
| 10 | - Document the 1.57 change better. |
| 11 | |
| c1dc6e7c |
12 | 1.57 |
| d8cb5b61 |
13 | - Win32/Cygwin/MinGW: if the performance counter drifts by more |
| 14 | than two seconds from the system clock (due to ntp adjustments, |
| c1dc6e7c |
15 | for example), recalibrate our internal counter: from Jan Dubois, |
| 16 | based on [cpan #5933] by Jerry D. Hedden. |
| 17 | |
| 1caec985 |
18 | 1.56 |
| 19 | - Give a clearer message if the tests timeout (perl change #22253) |
| 20 | - Don't use /tmp or its moral equivalents (perl bug #15036, |
| 21 | perl change #22258) |
| 22 | |
| b6136f41 |
23 | 1.55 |
| 24 | - Windows: ming32 patch from Mike Pomraning (use Perl's Const64() |
| 25 | instead of VC-specific i64 suffix) |
| 26 | |
| 0225372c |
27 | 1.54 |
| 28 | - Solaris: like Tru64 (dec_osf) also Solaris need -lrt for nanosleep |
| 29 | |
| 30 | 1.53 |
| 31 | - Windows: higher resolution time() by using the Windows |
| 32 | performance counter API, from Jan Dubois and Anton Shcherbinin. |
| 33 | The exact new higher resolution depends on the hardware, |
| 34 | but it should be quite a bit better than using the basic |
| 35 | Windows timers. |
| 36 | |
| 690f7c5f |
37 | 1.52 |
| 38 | - In AIX (v?) with perl 5.6.1 the HiRes.t can hang after |
| 39 | the subtest 18. No known analysis nor fix, but added |
| 40 | an alarm (that requires fork() and alarm()) to the test. |
| 41 | |
| b85af263 |
42 | 1.51 |
| 43 | - doc tweaks from mjd (perl change #20456) |
| 44 | - NCR MP-RAS hints file added (svr4.pl) (perl change #21249) |
| 45 | |
| d7358e6a |
46 | 1.50 |
| 47 | - add a message (for non-core builds) to Makefile.PL about |
| 48 | the LC_ALL=C workaround |
| 49 | - &Time::HiRes::d_nanosleep was broken (perl change #20131) |
| 50 | - the nanosleep() probe was broken (perl change #20061) |
| 51 | - use existence instead of definedness for feature probes |
| 52 | (perl change #20043) |
| 53 | - MPE/iX tweak (perl change #20042) |
| 54 | - do not use HAS_NANOSLEEP (perl change #19898) |
| 55 | |
| df16a331 |
56 | 1.49 |
| 57 | - UVuf for non-IVSIZE platforms (from Keiichiro Nagano) |
| 58 | - OS/2 can always mix subsecond sleeps with signals |
| 59 | (part of perl change #19789) |
| 60 | |
| 2d9815af |
61 | 1.48 |
| 62 | - workaround for buggy gcc 2.95.3 in openbsd/sparc64 |
| 63 | (perl change #19592) |
| 64 | |
| 1a08a6ab |
65 | 1.47 |
| 2d9815af |
66 | - do not use -lrt in Linux (from March Lehmann, perl change #19449) |
| 1a08a6ab |
67 | - unnecessary (nanosleep is in libc anyway) |
| 68 | - harmful (-lrt slows down execution) |
| 69 | - incompatible (with many distributions' pthreads) |
| 70 | |
| 25ca0970 |
71 | 1.46 |
| 72 | - do not create files in blib directories under core |
| 73 | (perl change #19160, from rgs) |
| 74 | - detypo s/VTLARM/VTARLM/ (perl change #19328, from mjd) |
| 75 | |
| 76 | 1.45 |
| 77 | - guarantee that $xdefine in HiRes.t is always defined |
| 78 | (perl change #19109, from IlyaZ) |
| 79 | - a cleaner way to detect PERL_CORE (perl change #19111, |
| 80 | from IlyaZ) |
| 81 | |
| 0be47ac6 |
82 | 1.44 |
| 83 | - add hints/irix.pl to turn off overly POSIX flags that |
| 84 | cause hide struct timespec to be hidden (and compilation |
| 25ca0970 |
85 | to fail) (bleadperl change #19085) |
| 0be47ac6 |
86 | - documentation tweaks |
| 87 | |
| a0c8e3cf |
88 | 1.43 |
| 89 | - add c:/temp to the list of temp directories to probe |
| 90 | so that cygwin (and win*?) builds are happy. This was |
| 91 | needed at least in my cygwin 1.3.20/w2k setup. |
| 92 | |
| 98b50af3 |
93 | 1.42 |
| 94 | - modernize the constants code (from Nicholas Clark) |
| 95 | |
| 96 | 1.41 |
| 97 | - At some point the ability to figure our the correct incdir |
| 98 | for EXTERN.h (either a core perl build, or an installed perl) |
| 99 | had broken (which lead into all test compiles failing with |
| 100 | a core perl build, but thanks to the robustness of Makefile.PL |
| a0c8e3cf |
101 | nothing of this was visible). The brokenness seemed to be |
| 102 | caused by $ENV{PERL_CORE} not being on for core builds? |
| 103 | Now stole a trick from the Encode that sets $ENV{PERL_CORE} |
| 104 | right, and both styles of build should work again. |
| 98b50af3 |
105 | |
| 106 | 1.40 |
| 107 | - Nicholas Clark noticed that the my_catdir() emulation function |
| 108 | was broken (which means that we didn't really work for Perls |
| 109 | 5.002 and 5.003) |
| 110 | - inspired by fixing the above made the whole Makefile.PL -w |
| 111 | and strict clean |
| 112 | - tightened up the Makefile.PL output, less whitespace |
| 113 | |
| 6a20eacc |
114 | 1.39 |
| 115 | - fix from Craig Berry for better building in VMS with PERL_CORE |
| 116 | |
| 3f2ee006 |
117 | 1.38 |
| 118 | - no functional changes |
| 119 | - move lib/Time/HiRes.pm as Hires.pm |
| 120 | - libraries scanning was slightly broken (always scanned |
| 121 | for a library even when $Config{libs} already had it) |
| 122 | |
| 123 | 1.37 |
| 124 | - Ray Zimmerman ran into a race condition in Mac OS X. |
| 125 | A 0.01-second alarm fired before the test expected. |
| 126 | The test first slept indefinitely (blocking for signals) |
| 127 | and only after that tested for the signal having been sent. |
| 128 | Since the signal had already been sent, the test #12 never |
| 129 | completed. The solution: test first, then block. |
| 130 | - default to being silent on all probing attempts, set the |
| 131 | environment variable VERBOSE to a true value to see the |
| 132 | details (the probing command and the possible errors) |
| 133 | |
| 134 | 1.36 |
| 135 | - do not clear MAN3PODS in Makefile.PL (Radoslaw Zielinski) |
| 136 | - INSTALLDIRS => 'perl' missing which means that Time::HiRes |
| 137 | cannot be upgraded from CPAN to override the 5.8.0 version |
| 138 | (Guido A. Ostkamp) |
| 139 | - Time::HiRes 1.35 could not be dropped as-is to bleadperl |
| 140 | because the include directories did not adjust themselves |
| 141 | if $ENV{PERL_CORE} (Hugo van der Sanden) |
| 142 | - add documentation about the restart of select() under alarm() |
| 143 | |
| 144 | 1.35 |
| 145 | - small documentation tweaks |
| 146 | |
| 147 | |
| 148 | 1.34 |
| 149 | - better VMS operation (Craig Berry) |
| 150 | |
| 151 | 1.33 |
| 152 | - our time machine is accelerating: now works with Perl 5.004_01 |
| 153 | (tried with 5.003_07 and 5.002 but I get segmentation faults |
| 154 | from running the Makefile.PL with those in Tru64 4.0D) |
| 155 | |
| 156 | 1.32 |
| 157 | - backward compatibility (pre-5.6.0) tweaks: |
| 158 | - no XSLoader in 5.00503, use DynaLoader instead |
| 159 | - no SvPV_nolen, either |
| 160 | - no PerlProc_pause(), either |
| 161 | - now tested with 5.00404 and 5.00503 |
| 162 | - Makefile.PL requires 5.00404 (no more 5.002) |
| 163 | - use nanosleep instead of usleep, if it is available (Wilson Snyder) |
| 164 | (this means that one can mix subsecond sleeps with alarms) |
| 165 | - because of nanosleep we probe for -lrt and -lposix4 |
| 166 | - the existence of getitimer/nanosleep/setitimer/ualarm/usleep |
| 167 | is available by exportable constants Time::HiRes::d_func |
| 168 | (since older Perl do not have them in %Config, and even |
| 169 | 5.8.0 does not probe for nanosleep) |
| 170 | |
| 171 | 1.31 |
| 172 | - backward compatibility (pre-5.6.1) tweaks: |
| 173 | - define NV if no NVTYPE |
| 174 | - define IVdf if needed (note: the Devel::PPPort |
| 175 | in 5.8.0 does not try hard hard enough since |
| 176 | the IVSIZE might not be defined) |
| 177 | - define NVgf if needed |
| 178 | - grab the typemap from 5.8.0 for the NV stuff |
| 179 | 1.30 |
| 180 | |
| 181 | - release 1.29_02 as 1.30 |
| 182 | |
| 183 | 1.29_02 |
| 184 | |
| 185 | - fix a silly unclosed comment typo in HiRes.xs |
| 186 | - document and export REALTIME_REALPROF (Solaris) |
| 187 | |
| 188 | 1.29_01 |
| 189 | |
| 190 | - only getitimer(ITIMER_REAL) available in Cygwin and Win32 |
| 191 | (need to patch this also in Perl 5.[89]) |
| 192 | - remove CVS revision log from HiRes.xs |
| 193 | |
| 194 | 1.29_00 |
| 195 | |

| 260 | |
| 261 | The following changes were made on top of the changes |
| 262 | made for Time::HiRes during the Perl 5.7 development |
| 263 | cycle that culminated in the release of Perl 5.8.0. |
| 264 | |
| 265 | - add "require 5.005" to the Makefile.PL |
| 266 | - remove the REVISION section (CVS log) from HiRes.pm |
| 267 | - add jhi's copyright alongside Douglas' |
| 268 | - move HiRes.pm to lib/Time/ |
| 269 | - move HiRes.t to t/ |
| 270 | - modify HiRes.t to use $ENV{PERL_CORE} |
| 271 | - modify the original Time::HiRes version 1.20 Makefile.PL |
| 272 | to work both with Perl 5.8.0 and the new code with pre-5.8.0 |
| 273 | Perls (tried with 5.6.1) |
| 274 | - tiny tweaks and updates in README and TODO |
| 275 | - bump the VERSION to 1.29 |
| 276 | |
| dcf686c9 |
277 | 1.20 Wed Feb 24 21:30 1999 |
| 278 | - make our usleep and ualarm substitutes into hrt_usleep |
| 279 | and hrt_ualarm. This helps static links of Perl with other |
| 280 | packages that also have usleep, etc. From |
| 281 | Ilya Zakharevich <ilya@math.ohio-state.edu> |
| 282 | - add C API stuff. From Joshua Pritikin |
| 283 | <joshua.pritikin@db.com> |
| 3f2ee006 |
284 | - VMS Makefile.PL fun. From pvhp@forte.com (Peter Prymmer) |
| dcf686c9 |
285 | - hopefully correct "-lc" fix for SCO. |
| 286 | - add PPD stuff |
| 287 | |
| 288 | 1.19 Tue Sep 29 22:30 1998 |
| 289 | - put VMS gettimeofday() in. Patch is from Sebastian Bazley |
| 290 | <seb@stian.demon.co.uk> |
| 291 | - change GIMME_V to GIMME to help people with older versions of |
| 292 | Perl. |
| 293 | - fix Win32 version of gettimeofday(). It didn't affect anything, |
| 294 | but it confuses people reading the code when the return value |
| 295 | is backwards (0 is success). |
| 296 | - fix Makefile.PL (more) so that detection of gettimeofday is |
| 297 | more correct. |
| 298 | |
| 299 | 1.18 Mon Jul 6 22:40 1998 |
| 300 | - add usleep() for Win32. |
| 301 | - fix Makefile.PL to fix reported HP/UX feature where unresolved |
| 302 | externals still cause an executable to be generated (though no |
| 303 | x bit set). Thanks to David Kozinn for report and explanation. |
| 304 | Problems with the fix are mine :) |
| 305 | |
| 306 | 1.17 Wed Jul 1 20:10 1998 |
| 307 | - fix setitimer calls so microseconds is not more than 1000000. |
| 308 | Hp/UX 9 doesn't like that. Provided by Roland B Robert, PhD. |
| 3f2ee006 |
309 | - make Win32. We only get gettimeofday (the select hack doesn't |
| dcf686c9 |
310 | seem to work on my Win95 system). |
| 3f2ee006 |
311 | - fix test 4 on 01test.t. add test to see if time() and |
| dcf686c9 |
312 | Time::HiRes::time() are close. |
| 313 | |
| 314 | 1.16 Wed Nov 12 21:05 1997 |
| 315 | - add missing EXTEND in new gettimeofday scalar code. |
| 316 | |
| 317 | 1.15 Mon Nov 10 21:30 1997 |
| 318 | - HiRes.pm: update pod. Provided by Gisle Aas. |
| 319 | - HiRes.xs: if gettimeofday() called in scalar context, do |
| 320 | something more useful than before. Provided by Gisle Aas. |
| 321 | - README: tell of xsubpp '-nolinenumber' woes. thanks to |
| 322 | Edward Henigin <ed@texas.net> for pointing out the problem. |
| 323 | |
| 324 | 1.14 Wed Nov 5 9:40 1997 |
| 325 | - Makefile.PL: look for setitimer |
| 326 | - HiRes.xs: if missing ualarm, but we have setitimer, make up |
| 327 | our own setitimer. These were provided by Gisle Aas. |
| 328 | |
| 329 | 1.13 Tue Nov 4 23:30 1997 |
| 330 | - Makefile.PL: fix autodetect mechanism to do try linking in addition |
| 331 | to just compiling; should fix Linux build problem. Fix was provided |
| 332 | by Gisle Aas. |
| 333 | |
| 334 | 1.12 Sun Oct 12 12:00:00 1997 |
| 335 | - Makefile.PL: set XSOPT to '-nolinenumbers' to work around xsubpp bug; |
| 336 | you may need to comment this back out if you have an older xsubpp. |
| 337 | - HiRes.xs: set PROTOTYPES: DISABLE |
| 338 | |
| 339 | 1.11 Fri Sep 05 16:00:00 1997 |
| 340 | - Makefile.PL: |
| 341 | Had some line commented out that shouldn't have been (testing |
| 342 | remnants) |
| 343 | - README: |
| 344 | Previous version was corrupted. |
| 345 | |
| 346 | 1.10 Thu May 22 20:20:00 1997 |
| 347 | - HiRes.xs, HiRes.pm, t/*: |
| 348 | - only compile what we have OS support for (or can |
| 349 | fake with select()) |
| 350 | - only test what we compiled |
| 351 | - gross improvement to the test suite |
| 352 | - fix EXPORT_FAIL. |
| 353 | This work was all done by Roderick Schertler |
| 354 | <roderick@argon.org>. If you run Linux or |
| 355 | one of the other ualarm-less platoforms, and you like this |
| 356 | module, let Roderick know; without him, it still wouldn't |
| 357 | be working on those boxes... |
| 358 | - Makefile.PL: figure out what routines the OS has and |
| 359 | only build what we need. These bits were written by Jarkko |
| 360 | Hietaniemi <jhi@iki.fi>. Again, gratitude is due... |
| 361 | |
| 362 | 1.02 Mon Dec 30 08:00:00 1996 |
| 363 | - HiRes.pm: update documentation to say what to do when missing |
| 364 | ualarm() and friends. |
| 365 | - README: update to warn that ualarm() and friends need to exist |
| 366 | |
| 367 | 1.01 Fri Oct 17 08:00:00 1996 |
| 368 | - Makefile.PL: make XSPROTOARGS => '-noprototyopes' |
| 369 | - HiRes.pm: put blank line between __END__ and =head1 so that |
| 370 | pod2man works. |
| 371 | |
| 372 | 1.00 Tue Sep 03 13:00:00 1996 |
| 373 | - original version; created by h2xs 1.16 |
