2013-04-04perl: redirect stderr to /dev/null instead of closingLibravatar Thomas Rast1-3/+3
On my system, t9100.1 triggers the following warning: ==352== Syscall param write(buf) points to uninitialised byte(s) ==352== at 0x57119C0: __write_nocancel (in /lib64/libc-2.17.so) ==352== by 0x56AC1D2: _IO_file_write@@GLIBC_2.2.5 (in /lib64/libc-2.17.so) ==352== by 0x56AC0B1: new_do_write (in /lib64/libc-2.17.so) ==352== by 0x56AD3B4: _IO_do_write@@GLIBC_2.2.5 (in /lib64/libc-2.17.so) ==352== by 0x56AD6FE: _IO_file_overflow@@GLIBC_2.2.5 (in /lib64/libc-2.17.so) ==352== by 0x56AE3D8: _IO_default_xsputn (in /lib64/libc-2.17.so) ==352== by 0x56ACAA2: _IO_file_xsputn@@GLIBC_2.2.5 (in /lib64/libc-2.17.so) ==352== by 0x5682133: buffered_vfprintf (in /lib64/libc-2.17.so) ==352== by 0x567CE9D: vfprintf (in /lib64/libc-2.17.so) ==352== by 0x5687096: fprintf (in /lib64/libc-2.17.so) ==352== by 0x4E7AC5: vreportf (usage.c:15) ==352== by 0x4E7B14: die_builtin (usage.c:38) The actual complaint appears to be a bug in the underlying implementation. What's interesting here is that it is apparently _triggered_ by closing stderr, which results in (from strace) write(2, "fatal: Needed a single revision\n", 32) = -1 EBADF (Bad file descriptor) write(2, "\0", 1) = -1 EBADF (Bad file descriptor) Closing stderr is a bad idea anyway: there is a very real chance that we print fatal error messages to some other file that just happens to be opened on the now-free FD 2. So let's not do that. As pointed out by Eric Wong (thanks), the initial close needs to go: die() would again write nowhere if we close STDERR beforehand.

perl/Git.pm::cat_blob slurped everything in core only to write it out to a file descriptor, which was not a very smart thing to do. * jc/perl-cat-blob: Git.pm: fix cat_blob crashes on large files
2013-02-22Git.pm: fix cat_blob crashes on large filesLibravatar Joshua Clayton1-10/+7
Read and write each 1024 byte buffer, rather than trying to buffer the entire content of the file. We are only copying the contents to a file descriptor and do not use it ourselves. Previous code would crash on all files > 2 Gib, when the offset variable became negative (perhaps below the level of perl), resulting in a crash. On a 32 bit system, or a system with low memory it might crash before reaching 2 GiB due to memory exhaustion. This code may leave a partial file behind in case of failure, where the old code would leave a completely empty file. Neither version verifies the correctness of the content. Calling code must take care of verification and cleanup.

2013-02-09perl/Git.pm: fix get_tz_offset to properly handle DST boundary casesLibravatar Ben Walton1-3/+3
When passed a local time that was on the boundary of a DST change, get_tz_offset returned a GMT offset that was incorrect (off by one hour). This is because the time was converted to GMT and then back to a time stamp via timelocal() which cannot disambiguate boundary cases as noted in its documentation. Modify this algorithm, using an approach suggested in http://article.gmane.org/gmane.comp.version-control.git/213871 to first convert the timestamp in question to two broken down forms with localtime() and gmtime(), and then compute what timestamps these two broken down forms would represent in GMT (i.e. a timezone that does not have DST issues) by applying timegm() on them. The difference between the resulting timestamps is the timezone offset. This avoids the ambigious conversion and allows a correct time to be returned on every occassion.

2011-02-14perl: command_bidi_pipe() method should set-up git environmensLibravatar Masatake Osanai1-5/+20
When command_input_pipe and command_output_pipe are used as a method of a Git::repository instance, they eventually call into _cmd_exec method that sets up the execution environment such as GIT_DIR, GIT_WORK_TREE environment variables and the current working directory in the child process that interacts with the repository. command_bidi_pipe however didn't expect to be called as such, and lacked all these set-up. Because of this, a program that did this did not work as expected: my $repo = Git->repository(Directory => '/some/where/else'); my ($pid, $in, $out, $ctx) = $repo->command_bidi_pipe(qw(hash-object -w --stdin-paths)); This patch refactors the _cmd_exec into _setup_git_cmd_env that sets up the execution environment, and makes _cmd_exec and command_bidi_pipe to use it. Note that unlike _cmd_exec that execv's a git command as an external process, command_bidi_pipe is called from the main line of control, and the execution environment needs to be restored after open2() does its magic.

2010-09-27perl: bump the required Perl version to 5.8 from 5.6.[21]Libravatar Ævar Arnfjörð Bjarmason1-0/+1
Formalize our dependency on perl 5.8, bumped from 5.6.[12]. We already used the three-arg form of open() which was introduced in 5.6.1, but t/t9700/test.pl explicitly depended on 5.6.2. However git-add--interactive.pl has been failing on the 5.6 line since it was introduced in v1.5.0-rc0~12^2~2 back in 2006 due to this open syntax: sub run_cmd_pipe { my $fh = undef; open($fh, '-|', @_) or die; return <$fh>; } Which when executed dies on "Can't use an undefined value as filehandle reference". Several of our tests also fail on 5.6 (even more when compiled with NO_PERL_MAKEMAKER=1): t2016-checkout-patch.sh t3904-stash-patch.sh t3701-add-interactive.sh t7105-reset-patch.sh t7501-commit.sh t9700-perl-git.sh Our code is bitrotting on 5.6 with no-one interested in fixing it, and pinning us to such an ancient release of Perl is keeping us from using useful features introduced in the 5.8 release. The 5.6 series is now over 10 years old, and the 5.6.2 maintenance release almost 7. 5.8 on the other hand is more than 8 years old. All the modern Unix-like operating systems have now upgraded to it or a later version, and 5.8 packages are available for old IRIX, AIX Solaris and Tru64 systems.

2010-03-05git-svn: support fetch with autocrlf onLibravatar Erik Faye-Lund1-1/+1
Before commit d3c9634e, performing a "git svn rebase" that fetched a change containing CRLFs corrupted the git-svn meta-data. This was worked around in d3c9634e by setting core.autocrlf to "false" in the per-repo config when initing the clone. However, if the config variable was later changed, the corruption would still occur. This patch tries to fix it while allowing core.autocrlf to be enabled, by disabling filters when when hashing. git-svn is currently the only call-site for hash_and_insert_object (apart from the test-suite), so changing it should be safe.

2008-11-13Git.pm: Make _temp_cache use the repository directoryLibravatar Marten Svanfeldt (dev)1-5/+10
Update the usage of File::Temp->tempfile to place the temporary files within the repository directory instead of just letting Perl decide what directory to use, given there is a repository specified when requesting the temporary file. This is needed to be able to fix git-svn on msys as msysperl generates paths with UNIX-style paths (/tmp/xxx) while the git tools expect natvie path format (c:/..). The repository dir is stored in native format so by using it as the base directory for temporary files we always get a usable native full path.

2008-08-12Git.pm: Add faculties to allow temp files to be cachedLibravatar Marcus Griep1-2/+123
This patch offers a generic interface to allow temp files to be cached while using an instance of the 'Git' package. If many temp files are created and destroyed during the execution of a program, this caching mechanism can help reduce the amount of files created and destroyed by the filesystem. The temp_acquire method provides a weak guarantee that a temp file will not be stolen by subsequent requests. If a file is locked when another acquire request is made, a simple error is thrown.

This is mostly lifted from earlier series by Dan Zwell, but updated to use "git config --get-color" and "git config --get-colorbool" to make it simpler and more consistent with commands written in C. A new configuration color.interactive variable is like color.diff and color.status, and controls if "git-add -i" uses color. A set of configuration variables, color.interactive.<slot>, are used to define what color is used for the prompt, header, and help text. For perl scripts, Git.pm provides $repo->get_color() method, which takes the slot name and the default color, and returns the terminal escape sequence to color the output text. $repo->get_colorbool() method can be used to check if color is set to be used for a given operation.
