1Revision history for Perl extension Time::HiRes.
2
0225372c
RGS
31.54
4 - Solaris: like Tru64 (dec_osf) also Solaris need -lrt for nanosleep
5
61.53
7 - Windows: higher resolution time() by using the Windows
8 performance counter API, from Jan Dubois and Anton Shcherbinin.
9 The exact new higher resolution depends on the hardware,
10 but it should be quite a bit better than using the basic
11 Windows timers.

RGS
131.52
14 - In AIX (v?) with perl 5.6.1 the HiRes.t can hang after
15 the subtest 18. No known analysis nor fix, but added
16 an alarm (that requires fork() and alarm()) to the test.
17

JH
181.51
19 - doc tweaks from mjd (perl change #20456)
20 - NCR MP-RAS hints file added (svr4.pl) (perl change #21249)
21
d7358e6a
JH
221.50
23 - add a message (for non-core builds) to Makefile.PL about
24 the LC_ALL=C workaround
25 - &Time::HiRes::d_nanosleep was broken (perl change #20131)
26 - the nanosleep() probe was broken (perl change #20061)
27 - use existence instead of definedness for feature probes
28 (perl change #20043)
29 - MPE/iX tweak (perl change #20042)
30 - do not use HAS_NANOSLEEP (perl change #19898)
31
df16a331
JH
321.49
33 - UVuf for non-IVSIZE platforms (from Keiichiro Nagano)
34 - OS/2 can always mix subsecond sleeps with signals
35 (part of perl change #19789)
36
2d9815af
JH
371.48
38 - workaround for buggy gcc 2.95.3 in openbsd/sparc64
39 (perl change #19592)
40
1a08a6ab 411.47
2d9815af 42 - do not use -lrt in Linux (from March Lehmann, perl change #19449)
1a08a6ab
ML
43 - unnecessary (nanosleep is in libc anyway)
44 - harmful (-lrt slows down execution)
45 - incompatible (with many distributions' pthreads)
46
25ca0970
JH
471.46
48 - do not create files in blib directories under core
49 (perl change #19160, from rgs)
50 - detypo s/VTLARM/VTARLM/ (perl change #19328, from mjd)
51
521.45
53 - guarantee that $xdefine in HiRes.t is always defined
54 (perl change #19109, from IlyaZ)
55 - a cleaner way to detect PERL_CORE (perl change #19111,
56 from IlyaZ)
57
0be47ac6
JH
581.44
59 - add hints/irix.pl to turn off overly POSIX flags that
60 cause hide struct timespec to be hidden (and compilation
25ca0970 61 to fail) (bleadperl change #19085)
0be47ac6
JH
62 - documentation tweaks
63
a0c8e3cf
JH
641.43
65 - add c:/temp to the list of temp directories to probe
66 so that cygwin (and win*?) builds are happy. This was
67 needed at least in my cygwin 1.3.20/w2k setup.
68
98b50af3
JH
691.42
70 - modernize the constants code (from Nicholas Clark)
71
721.41
73 - At some point the ability to figure our the correct incdir
74 for EXTERN.h (either a core perl build, or an installed perl)
75 had broken (which lead into all test compiles failing with
76 a core perl build, but thanks to the robustness of Makefile.PL
a0c8e3cf
JH
77 nothing of this was visible). The brokenness seemed to be
78 caused by $ENV{PERL_CORE} not being on for core builds?
79 Now stole a trick from the Encode that sets $ENV{PERL_CORE}
80 right, and both styles of build should work again.
98b50af3
JH
81
821.40
83 - Nicholas Clark noticed that the my_catdir() emulation function
84 was broken (which means that we didn't really work for Perls
85 5.002 and 5.003)
86 - inspired by fixing the above made the whole Makefile.PL -w
87 and strict clean
88 - tightened up the Makefile.PL output, less whitespace
89
6a20eacc
HS
901.39
91 - fix from Craig Berry for better building in VMS with PERL_CORE
92
3f2ee006
HS
931.38
94 - no functional changes
95 - move lib/Time/HiRes.pm as Hires.pm
96 - libraries scanning was slightly broken (always scanned
97 for a library even when $Config{libs} already had it)
98
991.37
100 - Ray Zimmerman ran into a race condition in Mac OS X.
101 A 0.01-second alarm fired before the test expected.
102 The test first slept indefinitely (blocking for signals)
103 and only after that tested for the signal having been sent.
104 Since the signal had already been sent, the test #12 never
105 completed. The solution: test first, then block.
106 - default to being silent on all probing attempts, set the
107 environment variable VERBOSE to a true value to see the
108 details (the probing command and the possible errors)
109
1101.36
111 - do not clear MAN3PODS in Makefile.PL (Radoslaw Zielinski)
112 - INSTALLDIRS => 'perl' missing which means that Time::HiRes
113 cannot be upgraded from CPAN to override the 5.8.0 version
114 (Guido A. Ostkamp)
115 - Time::HiRes 1.35 could not be dropped as-is to bleadperl
116 because the include directories did not adjust themselves
117 if $ENV{PERL_CORE} (Hugo van der Sanden)
118 - add documentation about the restart of select() under alarm()
119
1201.35
121 - small documentation tweaks
122
123
1241.34
125 - better VMS operation (Craig Berry)
126
1271.33
128 - our time machine is accelerating: now works with Perl 5.004_01
129 (tried with 5.003_07 and 5.002 but I get segmentation faults
130 from running the Makefile.PL with those in Tru64 4.0D)
131
1321.32
133 - backward compatibility (pre-5.6.0) tweaks:
134 - no XSLoader in 5.00503, use DynaLoader instead
135 - no SvPV_nolen, either
136 - no PerlProc_pause(), either
137 - now tested with 5.00404 and 5.00503
138 - Makefile.PL requires 5.00404 (no more 5.002)
139 - use nanosleep instead of usleep, if it is available (Wilson Snyder)
140 (this means that one can mix subsecond sleeps with alarms)
141 - because of nanosleep we probe for -lrt and -lposix4
142 - the existence of getitimer/nanosleep/setitimer/ualarm/usleep
143 is available by exportable constants Time::HiRes::d_func
144 (since older Perl do not have them in %Config, and even
145 5.8.0 does not probe for nanosleep)
146
1471.31
148 - backward compatibility (pre-5.6.1) tweaks:
149 - define NV if no NVTYPE
150 - define IVdf if needed (note: the Devel::PPPort
151 in 5.8.0 does not try hard hard enough since
152 the IVSIZE might not be defined)
153 - define NVgf if needed
154 - grab the typemap from 5.8.0 for the NV stuff
1551.30
156
157 - release 1.29_02 as 1.30
158
1591.29_02
160
161 - fix a silly unclosed comment typo in HiRes.xs
162 - document and export REALTIME_REALPROF (Solaris)
163
1641.29_01
165
166 - only getitimer(ITIMER_REAL) available in Cygwin and Win32
167 (need to patch this also in Perl 5.[89])
168 - remove CVS revision log from HiRes.xs
169
1701.29_00

237 The following changes were made on top of the changes
238 made for Time::HiRes during the Perl 5.7 development
239 cycle that culminated in the release of Perl 5.8.0.
240
241 - add "require 5.005" to the Makefile.PL
242 - remove the REVISION section (CVS log) from HiRes.pm
243 - add jhi's copyright alongside Douglas'
244 - move HiRes.pm to lib/Time/
245 - move HiRes.t to t/
246 - modify HiRes.t to use $ENV{PERL_CORE}
247 - modify the original Time::HiRes version 1.20 Makefile.PL
248 to work both with Perl 5.8.0 and the new code with pre-5.8.0
249 Perls (tried with 5.6.1)
250 - tiny tweaks and updates in README and TODO
251 - bump the VERSION to 1.29
252

JH
2531.20 Wed Feb 24 21:30 1999
254 - make our usleep and ualarm substitutes into hrt_usleep
255 and hrt_ualarm. This helps static links of Perl with other
256 packages that also have usleep, etc. From
257 Ilya Zakharevich <ilya@math.ohio-state.edu>
258 - add C API stuff. From Joshua Pritikin
259 <joshua.pritikin@db.com>
3f2ee006 260 - VMS Makefile.PL fun. From pvhp@forte.com (Peter Prymmer)
dcf686c9
JH
261 - hopefully correct "-lc" fix for SCO.
262 - add PPD stuff
263
2641.19 Tue Sep 29 22:30 1998
265 - put VMS gettimeofday() in. Patch is from Sebastian Bazley
266 <seb@stian.demon.co.uk>
267 - change GIMME_V to GIMME to help people with older versions of
268 Perl.
269 - fix Win32 version of gettimeofday(). It didn't affect anything,
270 but it confuses people reading the code when the return value
271 is backwards (0 is success).
272 - fix Makefile.PL (more) so that detection of gettimeofday is
273 more correct.
274
2751.18 Mon Jul 6 22:40 1998
276 - add usleep() for Win32.
277 - fix Makefile.PL to fix reported HP/UX feature where unresolved
278 externals still cause an executable to be generated (though no
279 x bit set). Thanks to David Kozinn for report and explanation.
280 Problems with the fix are mine :)
281
2821.17 Wed Jul 1 20:10 1998
283 - fix setitimer calls so microseconds is not more than 1000000.
284 Hp/UX 9 doesn't like that. Provided by Roland B Robert, PhD.
3f2ee006 285 - make Win32. We only get gettimeofday (the select hack doesn't
dcf686c9 286 seem to work on my Win95 system).
3f2ee006 287 - fix test 4 on 01test.t. add test to see if time() and
dcf686c9
JH
288 Time::HiRes::time() are close.
289
2901.16 Wed Nov 12 21:05 1997
291 - add missing EXTEND in new gettimeofday scalar code.
292
2931.15 Mon Nov 10 21:30 1997
294 - HiRes.pm: update pod. Provided by Gisle Aas.
295 - HiRes.xs: if gettimeofday() called in scalar context, do
296 something more useful than before. Provided by Gisle Aas.
297 - README: tell of xsubpp '-nolinenumber' woes. thanks to
298 Edward Henigin <ed@texas.net> for pointing out the problem.
299
3001.14 Wed Nov 5 9:40 1997
301 - Makefile.PL: look for setitimer
302 - HiRes.xs: if missing ualarm, but we have setitimer, make up
303 our own setitimer. These were provided by Gisle Aas.
304
3051.13 Tue Nov 4 23:30 1997
306 - Makefile.PL: fix autodetect mechanism to do try linking in addition
307 to just compiling; should fix Linux build problem. Fix was provided
308 by Gisle Aas.
309
3101.12 Sun Oct 12 12:00:00 1997
311 - Makefile.PL: set XSOPT to '-nolinenumbers' to work around xsubpp bug;
312 you may need to comment this back out if you have an older xsubpp.
313 - HiRes.xs: set PROTOTYPES: DISABLE
314
3151.11 Fri Sep 05 16:00:00 1997
316 - Makefile.PL:
317 Had some line commented out that shouldn't have been (testing
318 remnants)
319 - README:
320 Previous version was corrupted.
321
3221.10 Thu May 22 20:20:00 1997
323 - HiRes.xs, HiRes.pm, t/*:
324 - only compile what we have OS support for (or can
325 fake with select())
326 - only test what we compiled
327 - gross improvement to the test suite
328 - fix EXPORT_FAIL.
329 This work was all done by Roderick Schertler
330 <roderick@argon.org>. If you run Linux or
331 one of the other ualarm-less platoforms, and you like this
332 module, let Roderick know; without him, it still wouldn't
333 be working on those boxes...
334 - Makefile.PL: figure out what routines the OS has and
335 only build what we need. These bits were written by Jarkko
336 Hietaniemi <jhi@iki.fi>. Again, gratitude is due...
337
3381.02 Mon Dec 30 08:00:00 1996
339 - HiRes.pm: update documentation to say what to do when missing
340 ualarm() and friends.
341 - README: update to warn that ualarm() and friends need to exist
342
3431.01 Fri Oct 17 08:00:00 1996
344 - Makefile.PL: make XSPROTOARGS => '-noprototyopes'
345 - HiRes.pm: put blank line between __END__ and =head1 so that
346 pod2man works.
347
3481.00 Tue Sep 03 13:00:00 1996
349 - original version; created by h2xs 1.16
