Revision history for Perl extension P4.
3.6001 Tue Aug 07 2007
Rework change 5787 in which support for taint checking of arguments
passed to P4::Run() was introduced. It turns out Scalar::Util, on
which this is based isn't distributed with Perl 5.6, so we can't
rely on it. This change simply disables the taint checking for
Perl 5.6 (no-one's using it because it only ever worked for Perl 5.8
users).
3.5943 Fri May 18 2007
Update P4Perl to build against 2007.2 API. The 2007.2 API has
a more traditional directory structure and P4Perl needs to
take that into account. This change also makes Makefile.PL
check that the version of the API being used is less than
or equal to the highest API version known when this version
was written.
Hopefully this will prevent people from struggling to build
older (stable) versions of P4Perl against recent APIs only
supported by the development builds.
3.5941 Fri May 18 2007
Documentation updates. Thanks to Steve Vance for pointing
out some of the shortcomings.
3.5869 Wed Mar 21 2007
Fix memory leaks. Thanks to John LoVerso and Sandy Currier for
tracking these down and sending me the patch.
3.5868 Wed Mar 21 2007
Port P4Perl to Perl 5.8.8. This change is spectacularly ugly,
but then so are the innards of Perl. See the long thread at:
http://www.nntp.perl.org/group/perl.perl5.porters/2006/06/msg114383.html
for details of the problem, and some discussion of solutions. I've
had to come up with a solution that doesn't involve patching people's
Perl installations, so my fix is even less easy on the eye but it
appears to work, and hopefully hasn't broken things for older
Perl versions.
3.5787 Wed Dec 06 2006
Update P4Perl to build against the 2006.2 API, and detect
(and reject) the passing of tainted data to P4::Run() as
a security measure.
3.5708 Wed Oct 18 2006
Add static P4::Identify() method to report the version of
P4Perl, and the API used to build it.
3.5704 Tue Oct 17 2006
Fix bug introduced in change 5677: the quoting of the const_char
definition wasn't good on Windows as it doesn't really understand
single quotes. Switched to using double-quotes.
3.5692 Fri Oct 06 2006
Add support for $p4->ServerLevel() which returns the server's
'server2' protocol level. This is not the same as, but is
closely aligned to, the server version and can be used
to test for feature availability. If you need explicit Perforce
version strings, run 'p4 info' in tagged mode and parse the
'serverVersion' string.
New feature requested by Robert Cowham.
3.5677 Tue Sept 26 2006
Rework P4Perl build script to support 2006.1 API. There were
some sweeping changes in the 2006.1 API which did away with the
old const_char definition. Unfortunately, since P4Perl has to
build with older APIs, I can't quite do the same. This change
tweaks the way that Makefile.PL determines the definition for
const_char so that (a) it's always 'const char' when a 2006.1
or later API is used, (b) it uses the platform specific hint
for older APIs (c) it falls back on 'char' in the absence of a
hint.
In an ideal world, we'd be able to compute the options based on
(a) OS, (b) compiler version (c) Perl version and (d) API version,
but that's tough to get right.
No functional change.
3.5624 Thu Aug 03 2006
Add hints file for Mac OS X from Tim Bunce (thanks Tim!).
3.5592 Thu Jul 20 2006
Bug fix: We were erroneously making a Perl scalar mortal (which causes
its reference count to be decremented when it goes out of scope) when
receiving binary data from the server. Decrementing the reference count
to early meant the scalar was being cleaned up when it was in fact
still in use.
This change simply removes the sv_2mortal() call.
Thanks to Mike Hall at National Instruments for finding this one.
3.5564 Fri Jun 30 2006
Fix memory leaks when dealing with tagged output with array
members. One of these days I'll get the hang of Perl's pesky
reference counting mechanism...
These leaks would have been most noticable with 'p4 filelog' (and
that's where they were reported), but in fact any command that
returned tagged output with array members would have leaked.
3.5396 Wed Apr 12 2006
x86_64 porting changes. Use INT2PTR and PTR2INT to handle the
stashing of the PerlClientApi pointer in a Perl scalar. This is
necessary because, despite all documentation to the contrary, an
I32 is not 64-bit capable on all 64-bit machines.
Also, the hints file now looks for x86_64 in the architecture
name and if it finds it, then const_char='const char' rather
than the default of 'char'.
3.5313 Tue Feb 07 2006
- Add new SetApiLevel() method to allow users to lock scripts to a
particular API level. This helps when upgrading to new servers
that extend support for tagged output to hitherto unsupported
commands (2005.2 did a lot of that).
See the C/C++ API Release Notes for the full details, but by way of
example, to lock scripts to the 2005.1 interface use:
$p4->SetApiLevel( 57 );
3.5259 Thu Jan 12 2006
- Update P4Perl for 2005.2 API changes. The 2005.2 API supplies forms
ready-parsed to the client when used in tagged mode. This is fine for
P4Perl, except that we were not caching the specdef if no parsing was
required and that meant that although forms could be converted to
hashes, the reverse direction was broken.
This change makes sure that we cache the specdef whenever it's
available.
3.5073 Wed Aug 03 2005
- Yet another P4::SetProg fix. Turns out the last change fixed
everything except the build script and it all worked...
unless you used the 2005.1 API which has a different format
for the Version file.
P4::SetProg is a no-op when P4Perl is built with an older API
so not identifying the API build properly breaks it thoroughly.
This change adapts P4Perl's setup script to support both
pre-2005.1 and 2005.1 formats, and gives the user the
chance to enter the API version manually if it can't be
automatically determined.
- Installers also included in this change
3.5067 Wed Jul 27 2005
- Bug fix: P4::SetProg() interface method was missing so SetProg
wasn't working too well!
3.5038 Mon Jul 04 2005
- Bug fix: Fix memory leaks in P4Perl reported by Craig Galley. Perl's
reference count garbage collection is not much fun to work with,
but hopefully this change plugs P4Perl's leaks. There's still a
leak that remains, but whether it's in P4Perl's code or just in
Perl I don't know. A loop like this:
while( 1 ) {
my $p4 = new P4;
}
will leak like a sieve but I'm pretty sure P4Perl is cleaning up
as it should. While it's very difficult to be certain with Perl's
memory mode, creating one P4 object and using it multiple times
now appears to be pretty steady.
- Also fixed use of uninitialized debug variable which could produce
debug output you hadn't asked for.
3.5035 Wed Jun 29 2005
- Bug fix: call ClientApi::SetProg() before every command instead of
just once as this value is not retained by the Perforce API.
3.4987 Fri Jun 03 2005
- Bug fix for tagged mode output from 'p4 diff2'. Diff2 is one of
the few (only?) commands to use variables of the form 'var' and
'var2' rather than 'var1' and 'var2'. Normally, if there's no
numeric suffix to a variable, P4Perl can assume it's looking at
the only instance of that variable in the output. In the case of
'p4 diff2', that's not true.
This change enables P4Perl to adapt to this change of circumstances
and convert a previously scalar member of the hash result into an
array member.
3.4873 Thu Mar 31 2005
- Bug fix: fix typos in test harness that were causing the tests
to fail.
3.4864 Mon Mar 21 2005
- Bug fix: Introduce workaround for obscure 2000.1/2000.2 protocol
bug that I really thought we'd seen the last of.
- Along the way, a total revamp of the debugging output - required
to diagnose the problem.
3.4856 Wed Mar 15 2005
- Rework P4::Errors() and P4::Warnings() so that they return a list
rather than an array. Perl seems to like this more and it's easy
to assign the list to an array should you wish to do so.
Note that this may cause some backwards-compatibility issues.
3.4831 Wed Feb 09 2005
- Change implementation of P4 class from being a blessed reference
to an integer (pointer) to a blessed reference to a hash. The
pointer is now stashed in a member of the hash. This makes it easier
for those that want to to subclass the P4 class and bolt on their own
functionality. No functional change.
3.4804 Thu Jan 20 2005
- Add support for P4::SetMaxResults() and P4::SetMaxScanRows() which
specify the desired limits for an instance of the P4 class. Note
that the limits remain in force until disabled by setting them to
zero.
3.4754 Tue Jan 11 2005
- Add support for passing multiple items of input to Perforce commands
that need them. The prime example is 'p4 password' which prompts the
user three times for password input (old password, new password and
new password again).
- Also add a P4::Password( $old, $new ) method to make it nice and
easy to use.
3.4698 Wed Dec 22 2004
- Bug fix. Correct client initialization so that it no longer causes
problems if the connection to the server fails for some reason.
- Also corrected the number of tests in the test harness.
3.4676 Mon Dec 06 2004
- Enable P4Perl to work against a server in unicode mode. This change
adds two new methods to the P4 class: SetCharset() and GetCharset()
which have the expected behaviour.
Thanks to Raymond Danks <raymond.danks@amd.com>.
- Also cleaned up the test harness a little
3.4667 Thu Dec 02 2004
- New ParseSpec() and FormatSpec() methods allow you to convert
specs between hash and string representations easily. Shortcut
methods Parse* and Format* are also defined. (i.e. FormatClient()
and ParseLabel() etc.)
- New methods IsTagged() and IsParseForms() tell you if your client
is in tagged/form parsing mode respectively. If you care.
- P4::Tag() is deprecated in favour of P4::Tagged(). P4::Tag() exists
for backwards compatibility
3.4608 Mon Oct 25 2004
- Bug fix: The SetInput() method was omitted in the big rewrite
so quite a lot was broken in builds 3.4579 and later. This
change fixes that omission, and adds support for 'p4 login'
too (that was how I discovered that SetInput() was missing).
3.4585 Mon Oct 18 2004
- Make P4Perl v3.x backwardly compatible with older versions of
the Perforce API.
3.4582 Mon Oct 18 2004
- Port previous change to NT. As usual, it's never simple. We
can't use fprintf( stderr, ... ) because of Perl's stupid
macro's. Hence a lot of fprintf()'s got changed to printf()'s.
- A couple of other minor changes and bugfixes.
3.4579 Fri Oct 15 2004
- Total rewrite. There's no need for P4::Client anymore, P4.pm is
now completely standalone. Of course that means that to build
P4.pm, you need to go through the same procedure you used to use
for P4-Client. C'est-la-vie. Internally, things are much cleaner
and now P4Perl shares the same architecture as P4Ruby so porting
new features and bug fixes between them should be much easier.
- Note that in the course of this change, the clunky DoPerlDiffs()
and DoP4Diffs() methods have been pruned. If you're using
DoPerlDiffs(), and you want to continue to do so, you'll need to
either ) continue using a 1.x build.
- Also note that errors and warnings now go to separate arrays
by default (so you can take note of errors, but ignore warnings
in your scripts). Users wanting the old behaviour must now
call P4::MergeErrors( 1 ).
- So why no version '2'? Simple really, P4::Client was already at
version 2, and I didn't want to confuse things by having people
think that P4::Client might be more recent/or on a par with P4.
Hence the jump straight to v3.
1.4320 Wed Jun 09 2004
- Bug fix. Fix the test script so that it handles both tagged and
non-tagged output for "p4 info". Tagged support for "p4 info" was
added in 2003.2. Thanks to Jeremy Bopp.
1.3550 Wed Aug 06 2003
- Add support for OutputBinary() to P4Perl classes. This allow
"p4 print" to work with binary files, and text files on clients
with non-native line endings.
- Re-add __END__ tag accidentally deleted in previous change
1.3537 Tue Aug 05 2003
- Documentation change. Added docs for P4::SubmitSpec and
P4::SetInput(). No functional change.
1.2587 Fri Jan 10 2003
- Documentation change. Added docs for P4::Error and P4::ErrorCount.
No functional change
1.2003 Wed Aug 07 2002
- MakeMaker tweaks. No functional change.
1.1733 Tue Apr 30 2002
- Documentation update and GA release.
0.982 Tue Oct 23 2001
- Fixed test.pl which was choking on test 6 due to ParseForms()
not having been called.
- Fixed return scheme so that an empty list rather than undef
is returned in array context when there are no results.
0.960 Fri Oct 19 2001
- Added sample code in example.pl
- Changed SetXXX/GetXXX shortcuts to FetchXXX and SaveXXX since
GetClient()/SetClient() were already in use - damn!
- Changed return scheme so that in scalar context Run() returns
an array reference if there is more than one result. Better
than a flat string which you then have to parse.
- Added PPD file contributed by George Ibbott
<gibbott@bakerstreettech.com>
0.931 Mon Oct 8 2001
- Enhanced interface with some shortcuts for common functions
and made it easy to use the form parsing capabilities of
P4::Client v 1.931.
0.10 Mon Oct 1 2001
- Initial version.
