git-svn: fix auth parameter handling on SVN 1.9.0+

2016-01-27T06:30:02Z

For users with "store-passwords = no" set in the "[auth]" section of their ~/.subversion/config, SVN 1.9.0+ would fail with the following message when attempting to call svn_auth_set_parameter: Value is not a string (or undef) at Git/SVN/Ra.pm Ironically, this breakage was caused by r1553823 in subversion: "Make svn_auth_set_parameter() usable from Perl bindings." Since 2007 (602015e0e6ec), git-svn has used a workaround to make svn_auth_set_parameter usable internally. However this workaround breaks under SVN 1.9+, which deals properly with the type mapping and fails to recognize our workaround. For pre-1.9.0 SVN, we continue to use the existing workaround for the lack of proper type mapping in the bindings. Tested under subversion 1.6.17 and 1.9.3. I've also verified r1553823 was not backported to SVN 1.8.x: BRANCH=http://svn.apache.org/repos/asf/subversion/branches/1.8.x svn log -v $BRANCH/subversion/bindings/swig/core.i ref: https://bugs.debian.org/797705 Cc: 797705@bugs.debian.org Reported-by: Thierry Vignaud Signed-off-by: Eric Wong Tested-by: Thierry Vignaud Signed-off-by: Junio C Hamano

git-svn: improve rebase/mkdirs performance

2015-11-10T01:35:01Z

Processing empty_dir directives becomes extremely slow for svn repositories with a large enough history. This is due to using a single hash to store the list of empty directories, with the expensive step being purging items from that hash using grep+delete. Storing directories in a hash of hashes improves the performance of this purge step and removes a potentially lengthy delay after every rebase/mkdirs command. The svn repository with this behaviour has 110K commits with unhandled.log containing 170K empty_dir directives. This takes 10 minutes to process when using a single hash, vs 3 seconds with a hash of hashes. Signed-off-by: Dair Grant Signed-off-by: Eric Wong

send-email: reduce dependencies impact on parse_address_line

2015-07-07T21:38:20Z

parse_address_line had not the same behavior whether the user had Mail::Address or not. Teach parse_address_line to behave like Mail::Address. When the user input is correct, this implementation behaves exactly like Mail::Address except when there are quotes inside the name: "Jane Do"e In this case the result of parse_address_line is: With M::A : "Jane Do" e Without : "Jane Do e" When the user input is not correct, the behavior is also mostly the same. Unlike Mail::Address, this doesn't parse groups and recursive commentaries. Signed-off-by: Remi Lespinet Signed-off-by: Matthieu Moy Signed-off-by: Junio C Hamano

Git::SVN::*: avoid premature FileHandle closure

2015-02-26T22:02:34Z

Since b19138b (git-svn: Make it incrementally faster by minimizing temp files, v1.6.0), git-svn has been using the Git.pm temp_acquire and temp_release mechanism to avoid unnecessary temp file churn and provide a speed boost. However, that change introduced a call to temp_acquire inside the Git::SVN::Fetcher::close_file function for an 'svn_hash' temp file. Because an SVN::Pool is active at the time this function is called, if the Git::temp_acquire function ends up actually creating a new FileHandle for the temp file (which it will the first time it's called with the name 'svn_hash') that FileHandle will end up in the SVN::Pool and should that pool have SVN::Pool::clear called on it that FileHandle will be closed out from under Git::temp_acquire. Since the only call site to Git::temp_acquire with the name 'svn_hash' is inside the close_file function, if an 'svn_hash' temp file is ever created its FileHandle is guaranteed to be created in the active SVN::Pool. This has not been a problem in the past because the SVN::Pool was not being cleared. However, since dfa72fdb (git-svn: reload RA every log-window-size, v2.2.0) the pool has been getting cleared periodically at which point the FileHandle for the 'svn_hash' temp file gets closed. Any subsequent calls to Git::temp_acquire for 'svn_hash', however, succeed without creating/opening a new temporary file since it still has the now invalid FileHandle in its cache. Callers that then attempt to use that FileHandle fail with an error. We avoid this problem by making sure the 'svn_hash' temp file is created in the same place the 'svn_delta_...' and 'git_blob_...' temp files are (and then temp_release'd) so that it can be safely used inside the close_file function without having its FileHandle end up in an SVN::Pool that gets cleared. Additionally the Git.pm cat_blob function creates a bidirectional pipe FileHandle using the IPC::Open2::open2 function. If that handle is created too late, it also gets caught up in the SVN::Pool and incorrectly closed by the SVN::Pool::clear call. But this only seems to happen with more recent versions of Perl and svn. To avoid this problem we add an explicit call to _open_cat_blob_if_needed before the first call to SVN::Pool->new_default to make sure the open2 handle does not end up in the SVN::Pool.

git-svn: fix localtime=true on non-glibc environments

2015-02-26T22:02:34Z

git svn uses POSIX::strftime('%s', $sec, $min, ...) to make unix epoch time. But lowercase %s formatting character is a GNU extention. This causes problem in git svn fetch --localtime on non-glibc systems, such as msys or cygwin. Using Time::Local::timelocal($sec, $min, ...) fixes it. Signed-off-by: Ryuichi Kokubo Signed-off-by: Eric Wong Notes: lowercase %s format character in strftime is a GNU extension and not widely supported. POSIX::strftime affected by underlying crt's strftime because POSIX::strftime just calls crt's one. Time::Local is good function to replace POSIX::strftime because it's a perl core module function. Document about Time::Local. http://perldoc.perl.org/Time/Local.html These are specifications of strftime. The GNU C Library Reference Manual. http://www.gnu.org/software/libc/manual/html_node/Formatting-Calendar-Time.html perl POSIX module's strftime document. It does not have '%s'. http://perldoc.perl.org/POSIX.html strftime document of Microsort Windows C Run-Time library. https://msdn.microsoft.com/en-us/library/fe06s4ak.aspx The Open Group's old specification does not have '%s' too. http://pubs.opengroup.org/onlinepubs/007908799/xsh/strftime.html On my environment, following problems happened. - msys : git svn fetch does not progress at all with perl.exe consuming CPU. - cygwin : git svn fetch progresses but time stamp information is dropped. Every commits have unix epoch timestamp. I would like to thank git developer and contibutors. git helps me so much everyday. Thank you. Signed-off-by: Junio C Hamano

git-svn: lazy load some modules

2015-02-26T20:19:21Z

We can delay loading some modules until we need them for uncommon code paths. For example, persistent memoization is not often needed, so we can avoid loading the modules for it until we encounter svn::mergeinfo during fetch. This gives a tiny reduction in syscalls (from 15641 to 15305) when running "git svn info" and counting via "strace -fc". Further, more invasive work will be needed to noticeably improve performance.
