* git-svn: lazy load some modulesEric Wong2015-02-261-6/+7
| | | | | | | | | | | | | 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.

* git-svn: support for git-svn propsetAlfred Perlstein2014-12-091-1/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change allows git-svn to support setting subversion properties. It is useful for manually setting properties when committing to a subversion repo that *requires* properties to be set without requiring moving your changeset to separate subversion checkout in order to set props. This change is initially from David Fraser, appearing at: http://mid.gmane.org/1927112650.1281253084529659.JavaMail.root@klofta.sjsoft.com> They are now forward-ported to most recent git along with fixes to deal with files in subdirectories. Style and functional changes from Eric Wong have been taken in their entirety from: http://mid.gmane.org/20141201094911.GA13931@dcvr.yhbt.net There is a nit to point out: the code does not support adding props unless there are also content changes to the files as well. This is demonstrated in the testcase.

* Git 2.0: git svn: Set default --prefix='origin/' if --prefix is not givenJohan Herland2014-04-191-11/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | git-svn by default puts its Subversion-tracking refs directly in refs/remotes/*. This runs counter to Git's convention of using refs/remotes/$remote/* for storing remote-tracking branches. Furthermore, combining git-svn with regular git remotes run the risk of clobbering refs under refs/remotes (e.g. if you have a git remote called "tags" with a "v1" branch, it will overlap with the git-svn's tracking branch for the "v1" tag from Subversion. Even though the git-svn refs stored in refs/remotes/* are not "proper" remote-tracking branches (since they are not covered by a proper git remote's refspec), they clearly represent a similar concept, and would benefit from following the same convention. For example, if git-svn tracks Subversion branch "foo" at refs/remotes/foo, and you create a local branch refs/heads/foo to add some commits to be pushed back to Subversion (using "git svn dcommit), then it is clearly unhelpful of Git to throw warning: refname 'foo' is ambiguous. every time you checkout, rebase, or otherwise interact with the branch. The existing workaround for this is to supply the --prefix=quux/ to git svn init/clone, so that git-svn's tracking branches end up in refs/remotes/quux/* instead of refs/remotes/*. However, encouraging users to specify --prefix to work around a design flaw in git-svn is suboptimal, and not a long term solution to the problem. Instead, git-svn should default to use a non-empty prefix that saves unsuspecting users from the inconveniences described above. This patch will only affect newly created git-svn setups, as the --prefix option only applies to git svn init (and git svn clone). Existing git-svn setups will continue with their existing (lack of) prefix. Also, if anyone somehow prefers git-svn's old layout, they can recreate that by explicitly passing an empty prefix (--prefix "") on the git svn init/clone command line. The patch changes the default value for --prefix from "" to "origin/", updates the git-svn manual page, and fixes the fallout in the git-svn testcases. (Note that this patch might be easier to review using the --word-diff and --word-diff-regex=. diff options.)

| | | | | | | | | | | | | | In Git v2.0, we will change the default --prefix for init/clone from none/empty to "origin/" (which causes SVN-tracking branches to be placed at refs/remotes/origin/* instead of refs/remotes/*). This patch warns users about the upcoming change, both in the git-svn manual page, and on stderr when running init/clone in the "multi-mode" without providing a --prefix.

* git-svn: fix signed commit parsingNicolas Vigier2013-10-101-1/+1
| | | | | | | | | | | | | | | | | | When parsing a commit object, git-svn wrongly think that a line containing spaces means the end of headers and the start of the commit message. In case of signed commit, the gpgsig entry contains a line with one space, so "git svn dcommit" will include part of the signature in the commit message. An example of such problem : http://svnweb.mageia.org/treasurer?view=revision&revision=86 This commit changes the regex to only match an empty line as separator between the headers and the commit message.

* | git svn: handle errors and concurrent commits in dcommitRobert Luberda2012-08-101-19/+55
|/ | | | | | | | | | | | | | | | | | | | | dcommit didn't handle errors returned by SVN and coped very poorly with concurrent commits that appear in SVN repository while dcommit was running. In both cases it left git repository in inconsistent state: index (which was reset with `git reset --mixed' after a successful commit to SVN) no longer matched the checkouted tree, when the following commit failed or needed to be rebased. See http://bugs.debian.org/676904 for examples. This patch fixes the issues by: - introducing error handler for dcommit. The handler will try to rebase or reset working tree before returning error to the end user. dcommit_rebase function was extracted out of cmd_dcommit to ensure consistency between cmd_dcommit and the error handler. - calling `git reset --mixed' only once after all patches are successfully committed to SVN. This ensures index is not touched for most of the time of dcommit run. Signed-off-by: Eric Wong <normalperson@yhbt.net>

* git-svn: don't create master if another head existsMarcin Owsiany2012-07-191-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | git-svn insists on creating the "master" head (unless it exists) on every "fetch". It is useful that it gets created initially, when no head exists - users expect this git convention of having a "master" branch on initial clone. However creating it when there already is another head does not provide any value - the ref is never updated, so it just gets stale after a while. Also, some users find it annoying that it gets recreated, especially when they would like the git branch names to follow SVN repository branch names. More background in http://thread.gmane.org/gmane.comp.version-control.git/115030 Make git-svn skip the "master" creation if HEAD already points at a valid head. This means "master" does get created on initial "clone" but does not get recreated once a user deletes it. Also, make post_fetch_checkout work with any head that is pointed to by HEAD, not just "master". Also, use fatal error handling consistent with the rest of the program for post_fetch_checkout.

* git-svn: use YAML format for mergeinfo cache when possibleJonathan Nieder2012-06-101-6/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since v1.7.0-rc2~11 (git-svn: persistent memoization, 2010-01-30), git-svn has maintained some private per-repository caches in .git/svn/.caches to avoid refetching and recalculating some mergeinfo-related information with every "git svn fetch". These caches use the 'nstore' format from the perl core module Storable, which can be read and written quickly and was designed for transfer over the wire (the 'n' stands for 'network'). This format is endianness-independent and independent of floating-point representation. Unfortunately the format is *not* independent of the perl version --- new perl versions will write files that very old perl cannot read. Worse, the format is not independent of the size of a perl integer. So if you toggle perl's use64bitint compile-time option, then using 'git svn fetch' on your old repositories produces errors like this: Byte order is not compatible at ../../lib/Storable.pm (autosplit into ../../lib/auto/Storable/_retrieve.al) line 380, at /usr/share/perl/5.12/Memoize/Storable.pm line 21 That is, upgrading perl to a version that uses use64bitint for the first time makes git-svn suddenly refuse to fetch in existing repositories. Removing .git/svn/.caches lets git-svn recover. It's time to switch to a platform independent serializer backend with better compatibility guarantees. This patch uses YAML::Any. Other choices were considered: - thawing data from Data::Dumper involves "eval". Doing that without creating a security risk is fussy. - the JSON API works on scalars in memory and doesn't provide a standard way to serialize straight to disk. YAML::Any is reasonably fast and has a pleasant API. In most backends, LoadFile() reads the entire file into a scalar anyway and converts it as a second step, but having an interface that allows the deserialization to happen on the fly without a temporary is still a comfort. YAML::Any is not a core perl module, so we take care to use it when and only when it is available. Installations without that module should fall back to using Storable with all its quirks, keeping their cache files in .git/svn/.caches/*.db Installations with YAML peacefully coexist by keeping a separate set of cache files in .git/svn/.caches/*.yaml. In most cases, switching between is a one-time thing, so it doesn't seem worth the complication to migrate existing caches. The upshot: after this patch, as long as YAML::Any is installed you can move your git repository between machines with different perl installations and "git svn fetch" will work fine. If you do not have YAML::Any, the behavior is unchanged (and in particular does not get any worse).

* git-svn: make Git::SVN::RA a separate fileJonathan Nieder2012-06-101-611/+1
| | | | | | | | | | | | | | | | | This slices off another 600 or so lines from the frighteningly long git-svn.perl script. The Git::SVN::Ra interface is similar enough to SVN::Ra that it is probably safe to ignore most of its implementation on first reading. (Documenting or moving functions that do not fit that pattern is left as an exercise to the interested reader.) [ew: rebased and fixed conflict against commit c26ddce86d7215b4d9687bd4c6b5dd43a3fabf31 (git-svn: platform auth providers are working only on 1.6.15 or newer)] Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: make Git::SVN::Editor a separate fileJonathan Nieder2012-06-101-470/+2
| | | | | | | | | This makes the git-svn script shorter and less scary for beginners to read through for the first time. Take the opportunity to explain the purpose and basic interface of the Git::SVN::Editor class while at it.

* | git-svn: make Git::SVN::Fetcher a separate fileJonathan Nieder2012-05-291-505/+2
| | | | | | | | | | | | | | | | | | | | This patch removes a chunk of code (the Git::SVN::Fetcher consumer of libsvn's tree delta protocol) from git-svn.perl and documents its interface so the hurried reader does not have to read that code right away.

* | git-svn: rename SVN::Git::* packages to Git::SVN::*Jonathan Nieder2012-05-291-25/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Using names in the Git:: namespace means these cannot conflict with a hypothetical binding teaching Subversion to interact with git repositories. Currently the packages are private to git-svn.perl so the choice of name isn't likely to make much difference. This change is mainly meant as preparation for splitting out the packages in question as modules on the public search path.
