dcf686c9 1Revision history for Perl extension Time::HiRes.
2
1a08a6ab 31.47
4 - do not use -lrt in Linux (from March Lehmann)
5 - unnecessary (nanosleep is in libc anyway)
6 - harmful (-lrt slows down execution)
7 - incompatible (with many distributions' pthreads)
8
25ca0970 91.46
10 - do not create files in blib directories under core
11 (perl change #19160, from rgs)
12 - detypo s/VTLARM/VTARLM/ (perl change #19328, from mjd)
13
141.45
15 - guarantee that $xdefine in HiRes.t is always defined
16 (perl change #19109, from IlyaZ)
17 - a cleaner way to detect PERL_CORE (perl change #19111,
18 from IlyaZ)
19
0be47ac6 201.44
21 - add hints/irix.pl to turn off overly POSIX flags that
22 cause hide struct timespec to be hidden (and compilation
25ca0970 23 to fail) (bleadperl change #19085)
0be47ac6 24 - documentation tweaks
25
a0c8e3cf 261.43
27 - add c:/temp to the list of temp directories to probe
28 so that cygwin (and win*?) builds are happy. This was
29 needed at least in my cygwin 1.3.20/w2k setup.
30
98b50af3 311.42
32 - modernize the constants code (from Nicholas Clark)
33
341.41
35 - At some point the ability to figure our the correct incdir
36 for EXTERN.h (either a core perl build, or an installed perl)
37 had broken (which lead into all test compiles failing with
38 a core perl build, but thanks to the robustness of Makefile.PL
a0c8e3cf 39 nothing of this was visible). The brokenness seemed to be
40 caused by $ENV{PERL_CORE} not being on for core builds?
41 Now stole a trick from the Encode that sets $ENV{PERL_CORE}
42 right, and both styles of build should work again.
98b50af3 43
441.40
45 - Nicholas Clark noticed that the my_catdir() emulation function
46 was broken (which means that we didn't really work for Perls
47 5.002 and 5.003)
48 - inspired by fixing the above made the whole Makefile.PL -w
49 and strict clean
50 - tightened up the Makefile.PL output, less whitespace
51
6a20eacc 521.39
53 - fix from Craig Berry for better building in VMS with PERL_CORE
54
3f2ee006 551.38
56 - no functional changes
57 - move lib/Time/HiRes.pm as Hires.pm
58 - libraries scanning was slightly broken (always scanned
59 for a library even when $Config{libs} already had it)
60
611.37
62 - Ray Zimmerman ran into a race condition in Mac OS X.
63 A 0.01-second alarm fired before the test expected.
64 The test first slept indefinitely (blocking for signals)
65 and only after that tested for the signal having been sent.
66 Since the signal had already been sent, the test #12 never
67 completed. The solution: test first, then block.
68 - default to being silent on all probing attempts, set the
69 environment variable VERBOSE to a true value to see the
70 details (the probing command and the possible errors)
71
721.36
73 - do not clear MAN3PODS in Makefile.PL (Radoslaw Zielinski)
74 - INSTALLDIRS => 'perl' missing which means that Time::HiRes
75 cannot be upgraded from CPAN to override the 5.8.0 version
76 (Guido A. Ostkamp)
77 - Time::HiRes 1.35 could not be dropped as-is to bleadperl
78 because the include directories did not adjust themselves
79 if $ENV{PERL_CORE} (Hugo van der Sanden)
80 - add documentation about the restart of select() under alarm()
81
821.35
83 - small documentation tweaks
84
85
861.34
87 - better VMS operation (Craig Berry)
88
891.33
90 - our time machine is accelerating: now works with Perl 5.004_01
91 (tried with 5.003_07 and 5.002 but I get segmentation faults
92 from running the Makefile.PL with those in Tru64 4.0D)
93
941.32
95 - backward compatibility (pre-5.6.0) tweaks:
96 - no XSLoader in 5.00503, use DynaLoader instead
97 - no SvPV_nolen, either
98 - no PerlProc_pause(), either
99 - now tested with 5.00404 and 5.00503
100 - Makefile.PL requires 5.00404 (no more 5.002)
101 - use nanosleep instead of usleep, if it is available (Wilson Snyder)
102 (this means that one can mix subsecond sleeps with alarms)
103 - because of nanosleep we probe for -lrt and -lposix4
104 - the existence of getitimer/nanosleep/setitimer/ualarm/usleep
105 is available by exportable constants Time::HiRes::d_func
106 (since older Perl do not have them in %Config, and even
107 5.8.0 does not probe for nanosleep)
108
1091.31
110 - backward compatibility (pre-5.6.1) tweaks:
111 - define NV if no NVTYPE
112 - define IVdf if needed (note: the Devel::PPPort
113 in 5.8.0 does not try hard hard enough since
114 the IVSIZE might not be defined)
115 - define NVgf if needed
116 - grab the typemap from 5.8.0 for the NV stuff
1171.30
118
119 - release 1.29_02 as 1.30
120
1211.29_02
122
123 - fix a silly unclosed comment typo in HiRes.xs
124 - document and export REALTIME_REALPROF (Solaris)
125
1261.29_01
127
128 - only getitimer(ITIMER_REAL) available in Cygwin and Win32
129 (need to patch this also in Perl 5.[89])
130 - remove CVS revision log from HiRes.xs
131
1321.29_00

199 The following changes were made on top of the changes
200 made for Time::HiRes during the Perl 5.7 development
201 cycle that culminated in the release of Perl 5.8.0.
202
203 - add "require 5.005" to the Makefile.PL
204 - remove the REVISION section (CVS log) from HiRes.pm
205 - add jhi's copyright alongside Douglas'
206 - move HiRes.pm to lib/Time/
207 - move HiRes.t to t/
208 - modify HiRes.t to use $ENV{PERL_CORE}
209 - modify the original Time::HiRes version 1.20 Makefile.PL
210 to work both with Perl 5.8.0 and the new code with pre-5.8.0
211 Perls (tried with 5.6.1)
212 - tiny tweaks and updates in README and TODO
213 - bump the VERSION to 1.29
214
dcf686c9 2151.20 Wed Feb 24 21:30 1999
216 - make our usleep and ualarm substitutes into hrt_usleep
217 and hrt_ualarm. This helps static links of Perl with other
218 packages that also have usleep, etc. From
219 Ilya Zakharevich <ilya@math.ohio-state.edu>
220 - add C API stuff. From Joshua Pritikin
221 <joshua.pritikin@db.com>
3f2ee006 222 - VMS Makefile.PL fun. From pvhp@forte.com (Peter Prymmer)
dcf686c9 223 - hopefully correct "-lc" fix for SCO.
224 - add PPD stuff
225
2261.19 Tue Sep 29 22:30 1998
227 - put VMS gettimeofday() in. Patch is from Sebastian Bazley
228 <seb@stian.demon.co.uk>
229 - change GIMME_V to GIMME to help people with older versions of
230 Perl.
231 - fix Win32 version of gettimeofday(). It didn't affect anything,
232 but it confuses people reading the code when the return value
233 is backwards (0 is success).
234 - fix Makefile.PL (more) so that detection of gettimeofday is
235 more correct.
236
2371.18 Mon Jul 6 22:40 1998
238 - add usleep() for Win32.
239 - fix Makefile.PL to fix reported HP/UX feature where unresolved
240 externals still cause an executable to be generated (though no
241 x bit set). Thanks to David Kozinn for report and explanation.
242 Problems with the fix are mine :)
243
2441.17 Wed Jul 1 20:10 1998
245 - fix setitimer calls so microseconds is not more than 1000000.
246 Hp/UX 9 doesn't like that. Provided by Roland B Robert, PhD.
3f2ee006 247 - make Win32. We only get gettimeofday (the select hack doesn't
dcf686c9 248 seem to work on my Win95 system).
3f2ee006 249 - fix test 4 on 01test.t. add test to see if time() and
dcf686c9 250 Time::HiRes::time() are close.
251
2521.16 Wed Nov 12 21:05 1997
253 - add missing EXTEND in new gettimeofday scalar code.
254
2551.15 Mon Nov 10 21:30 1997
256 - HiRes.pm: update pod. Provided by Gisle Aas.
257 - HiRes.xs: if gettimeofday() called in scalar context, do
258 something more useful than before. Provided by Gisle Aas.
259 - README: tell of xsubpp '-nolinenumber' woes. thanks to
260 Edward Henigin <ed@texas.net> for pointing out the problem.
261
2621.14 Wed Nov 5 9:40 1997
263 - Makefile.PL: look for setitimer
264 - HiRes.xs: if missing ualarm, but we have setitimer, make up
265 our own setitimer. These were provided by Gisle Aas.
266
2671.13 Tue Nov 4 23:30 1997
268 - Makefile.PL: fix autodetect mechanism to do try linking in addition
269 to just compiling; should fix Linux build problem. Fix was provided
270 by Gisle Aas.
271
2721.12 Sun Oct 12 12:00:00 1997
273 - Makefile.PL: set XSOPT to '-nolinenumbers' to work around xsubpp bug;
274 you may need to comment this back out if you have an older xsubpp.
275 - HiRes.xs: set PROTOTYPES: DISABLE
276
2771.11 Fri Sep 05 16:00:00 1997
278 - Makefile.PL:
279 Had some line commented out that shouldn't have been (testing
280 remnants)
281 - README:
282 Previous version was corrupted.
283
2841.10 Thu May 22 20:20:00 1997
285 - HiRes.xs, HiRes.pm, t/*:
286 - only compile what we have OS support for (or can
287 fake with select())
288 - only test what we compiled
289 - gross improvement to the test suite
290 - fix EXPORT_FAIL.
291 This work was all done by Roderick Schertler
292 <roderick@argon.org>. If you run Linux or
293 one of the other ualarm-less platoforms, and you like this
294 module, let Roderick know; without him, it still wouldn't
295 be working on those boxes...
296 - Makefile.PL: figure out what routines the OS has and
297 only build what we need. These bits were written by Jarkko
298 Hietaniemi <jhi@iki.fi>. Again, gratitude is due...
299
3001.02 Mon Dec 30 08:00:00 1996
301 - HiRes.pm: update documentation to say what to do when missing
302 ualarm() and friends.
303 - README: update to warn that ualarm() and friends need to exist
304
3051.01 Fri Oct 17 08:00:00 1996
306 - Makefile.PL: make XSPROTOARGS => '-noprototyopes'
307 - HiRes.pm: put blank line between __END__ and =head1 so that
308 pod2man works.
309
3101.00 Tue Sep 03 13:00:00 1996
311 - original version; created by h2xs 1.16
