1 Revision history for Perl extension Time::HiRes.
4 - fix from Craig Berry for better building in VMS with PERL_CORE
7 - no functional changes
8 - move lib/Time/HiRes.pm as Hires.pm
9 - libraries scanning was slightly broken (always scanned
10 for a library even when $Config{libs} already had it)
13 - Ray Zimmerman ran into a race condition in Mac OS X.
14 A 0.01-second alarm fired before the test expected.
15 The test first slept indefinitely (blocking for signals)
16 and only after that tested for the signal having been sent.
17 Since the signal had already been sent, the test #12 never
18 completed. The solution: test first, then block.
19 - default to being silent on all probing attempts, set the
20 environment variable VERBOSE to a true value to see the
21 details (the probing command and the possible errors)
24 - do not clear MAN3PODS in Makefile.PL (Radoslaw Zielinski)
25 - INSTALLDIRS => 'perl' missing which means that Time::HiRes
26 cannot be upgraded from CPAN to override the 5.8.0 version
28 - Time::HiRes 1.35 could not be dropped as-is to bleadperl
29 because the include directories did not adjust themselves
30 if $ENV{PERL_CORE} (Hugo van der Sanden)
31 - add documentation about the restart of select() under alarm()
34 - small documentation tweaks
38 - better VMS operation (Craig Berry)
41 - our time machine is accelerating: now works with Perl 5.004_01
42 (tried with 5.003_07 and 5.002 but I get segmentation faults
43 from running the Makefile.PL with those in Tru64 4.0D)
46 - backward compatibility (pre-5.6.0) tweaks:
47 - no XSLoader in 5.00503, use DynaLoader instead
48 - no SvPV_nolen, either
49 - no PerlProc_pause(), either
50 - now tested with 5.00404 and 5.00503
51 - Makefile.PL requires 5.00404 (no more 5.002)
52 - use nanosleep instead of usleep, if it is available (Wilson Snyder)
53 (this means that one can mix subsecond sleeps with alarms)
54 - because of nanosleep we probe for -lrt and -lposix4
55 - the existence of getitimer/nanosleep/setitimer/ualarm/usleep
56 is available by exportable constants Time::HiRes::d_func
57 (since older Perl do not have them in %Config, and even
58 5.8.0 does not probe for nanosleep)
61 - backward compatibility (pre-5.6.1) tweaks:
62 - define NV if no NVTYPE
63 - define IVdf if needed (note: the Devel::PPPort
64 in 5.8.0 does not try hard hard enough since
65 the IVSIZE might not be defined)
66 - define NVgf if needed
67 - grab the typemap from 5.8.0 for the NV stuff
70 - release 1.29_02 as 1.30
74 - fix a silly unclosed comment typo in HiRes.xs
75 - document and export REALTIME_REALPROF (Solaris)
79 - only getitimer(ITIMER_REAL) available in Cygwin and Win32
80 (need to patch this also in Perl 5.[89])
81 - remove CVS revision log from HiRes.xs

150 The following changes were made on top of the changes
151 made for Time::HiRes during the Perl 5.7 development
152 cycle that culminated in the release of Perl 5.8.0.
154 - add "require 5.005" to the Makefile.PL
155 - remove the REVISION section (CVS log) from HiRes.pm
156 - add jhi's copyright alongside Douglas'
157 - move HiRes.pm to lib/Time/
159 - modify HiRes.t to use $ENV{PERL_CORE}
160 - modify the original Time::HiRes version 1.20 Makefile.PL
161 to work both with Perl 5.8.0 and the new code with pre-5.8.0
162 Perls (tried with 5.6.1)
163 - tiny tweaks and updates in README and TODO
164 - bump the VERSION to 1.29
166 1.20 Wed Feb 24 21:30 1999
167 - make our usleep and ualarm substitutes into hrt_usleep
168 and hrt_ualarm. This helps static links of Perl with other
169 packages that also have usleep, etc. From
170 Ilya Zakharevich <ilya@math.ohio-state.edu>
171 - add C API stuff. From Joshua Pritikin
172 <joshua.pritikin@db.com>
173 - VMS Makefile.PL fun. From pvhp@forte.com (Peter Prymmer)
174 - hopefully correct "-lc" fix for SCO.
177 1.19 Tue Sep 29 22:30 1998
178 - put VMS gettimeofday() in. Patch is from Sebastian Bazley
179 <seb@stian.demon.co.uk>
180 - change GIMME_V to GIMME to help people with older versions of
182 - fix Win32 version of gettimeofday(). It didn't affect anything,
183 but it confuses people reading the code when the return value
184 is backwards (0 is success).
185 - fix Makefile.PL (more) so that detection of gettimeofday is
188 1.18 Mon Jul 6 22:40 1998
189 - add usleep() for Win32.
190 - fix Makefile.PL to fix reported HP/UX feature where unresolved
191 externals still cause an executable to be generated (though no
192 x bit set). Thanks to David Kozinn for report and explanation.
193 Problems with the fix are mine :)
195 1.17 Wed Jul 1 20:10 1998
196 - fix setitimer calls so microseconds is not more than 1000000.
197 Hp/UX 9 doesn't like that. Provided by Roland B Robert, PhD.
198 - make Win32. We only get gettimeofday (the select hack doesn't
199 seem to work on my Win95 system).
200 - fix test 4 on 01test.t. add test to see if time() and
201 Time::HiRes::time() are close.
203 1.16 Wed Nov 12 21:05 1997
204 - add missing EXTEND in new gettimeofday scalar code.
206 1.15 Mon Nov 10 21:30 1997
207 - HiRes.pm: update pod. Provided by Gisle Aas.
208 - HiRes.xs: if gettimeofday() called in scalar context, do
209 something more useful than before. Provided by Gisle Aas.
210 - README: tell of xsubpp '-nolinenumber' woes. thanks to
211 Edward Henigin <ed@texas.net> for pointing out the problem.
213 1.14 Wed Nov 5 9:40 1997
214 - Makefile.PL: look for setitimer
215 - HiRes.xs: if missing ualarm, but we have setitimer, make up
216 our own setitimer. These were provided by Gisle Aas.
218 1.13 Tue Nov 4 23:30 1997
219 - Makefile.PL: fix autodetect mechanism to do try linking in addition
220 to just compiling; should fix Linux build problem. Fix was provided
223 1.12 Sun Oct 12 12:00:00 1997
224 - Makefile.PL: set XSOPT to '-nolinenumbers' to work around xsubpp bug;
225 you may need to comment this back out if you have an older xsubpp.
226 - HiRes.xs: set PROTOTYPES: DISABLE
228 1.11 Fri Sep 05 16:00:00 1997
230 Had some line commented out that shouldn't have been (testing
233 Previous version was corrupted.
235 1.10 Thu May 22 20:20:00 1997
236 - HiRes.xs, HiRes.pm, t/*:
237 - only compile what we have OS support for (or can
239 - only test what we compiled
240 - gross improvement to the test suite
242 This work was all done by Roderick Schertler
243 <roderick@argon.org>. If you run Linux or
244 one of the other ualarm-less platoforms, and you like this
245 module, let Roderick know; without him, it still wouldn't
246 be working on those boxes...
247 - Makefile.PL: figure out what routines the OS has and
248 only build what we need. These bits were written by Jarkko
249 Hietaniemi <jhi@iki.fi>. Again, gratitude is due...
251 1.02 Mon Dec 30 08:00:00 1996
252 - HiRes.pm: update documentation to say what to do when missing
253 ualarm() and friends.
254 - README: update to warn that ualarm() and friends need to exist
256 1.01 Fri Oct 17 08:00:00 1996
257 - Makefile.PL: make XSPROTOARGS => '-noprototyopes'
258 - HiRes.pm: put blank line between __END__ and =head1 so that
261 1.00 Tue Sep 03 13:00:00 1996
262 - original version; created by h2xs 1.16
