2012-10-10git svn: work around SVN 1.7 mishandling of svn:special changesLibravatar Jonathan Nieder1-1/+24
Subversion represents symlinks as ordinary files with content starting with "link " and the svn:special property set to "*". Thus a file can switch between being a symlink and a non-symlink simply by toggling its svn:special property, and new checkouts will automatically write a file of the appropriate type. Likewise, in subversion 1.6 and older, running "svn update" would notice changes in filetype and update the working copy appropriately. Starting in subversion 1.7 (issue 4091), changes to the svn:special property trip an assertion instead: $ svn up svn-tree Updating 'svn-tree': svn: E235000: In file 'subversion/libsvn_wc/update_editor.c' \ line 1583: assertion failed (action == svn_wc_conflict_action_edit \ || action == svn_wc_conflict_action_delete || action == \ svn_wc_conflict_action_replace) Revisions prepared with ordinary svn commands ("svn add" and not "svn propset") don't trip this because they represent these filetype changes using a replace operation, which is approximately equivalent to removal followed by adding a new file and works fine. Follow suit. Noticed using t9100. After this change, git-svn's file-to-symlink changes are sent in a format that modern "svn update" can handle and tests t9100.11-13 pass again.

2012-10-05git-svn: keep leading slash when canonicalizing paths (fallback case)Libravatar Jonathan Nieder1-1/+0
Subversion's svn_dirent_canonicalize() and svn_path_canonicalize() APIs keep a leading slash in the return value if one was present on the argument, which can be useful since it allows relative and absolute paths to be distinguished. When git-svn's canonicalize_path() learned to use these functions if available, its semantics changed in the corresponding way. Some new callers rely on the leading slash --- for example, if the slash is stripped out then _canonicalize_url_ourselves() will transform "proto://host/path/to/resource" to "proto://hostpath/to/resource". Unfortunately the fallback _canonicalize_path_ourselves(), used when the appropriate SVN APIs are not usable, still follows the old semantics, so if that code path is exercised then it breaks. Fix it to follow the new convention. Noticed by forcing the fallback on and running tests. Without this patch, t9101.4 fails: Bad URL passed to RA layer: Unable to open an ra_local session to \ URL: Local URL 'file://homejrnsrcgit-scratch/t/trash%20directory.\ t9101-git-svn-props/svnrepo' contains unsupported hostname at \ /home/jrn/src/git-scratch/perl/blib/lib/Git/SVN.pm line 148 With it, the git-svn tests pass again.

2012-10-05Make git-svn branch patterns match complete URLLibravatar Ammon Riley1-1/+3
When using the {word,[...]} style of configuration for tags and branches, it appears the intent is to only match whole path parts, since the words in the {} pattern are meta-character quoted. When the pattern word appears in the beginning or middle of the url, it's matched completely, since the left side, pattern, and (non-empty) right side are joined together with path separators. However, when the pattern word appears at the end of the URL, the right side is an empty pattern, and the resulting regex matches more than just the specified pattern. For example, if you specify something along the lines of branches = branches/project/{release_1,release_2} and your repository also contains "branches/project/release_1_2", you will also get the release_1_2 branch. By restricting the match regex with anchors, this is avoided. Signed-off-by: Ammon Riley <ammon.riley@gmail.com> Signed-off-by: Eric Wong <normalperson@yhbt.net>

The merge of branch2 into trunk will have svn:mergeinfo property references to both branch1 and branch2. When git-svn fetches the commit that merges branch2 (check_cherry_pick), it is necessary to eliminate the merged contents of branch1 as well as branch2, or else the merge will be incorrectly ignored as a cherry-pick.

2012-08-10git svn: reset invalidates the memoized mergeinfo cachesLibravatar Peter Baumann1-2/+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'. This memoization can cause problems, e.g consider the following case: SVN repo: ... - a - b - c - m <- trunk \ / d - e <- branch1 The Git import of the above repo is at commit 'a' and doesn't know about the branch1. In case of an 'git svn rebase', only the trunk of the SVN repo is imported. During the creation of the git commit 'm', git svn uses the svn:mergeinfo property and tries to find the corresponding git commit 'e' to create 'm' with 'c' and 'e' as parents. But git svn rebase only imports the current branch so commit 'e' is not imported. Therefore git svn fails to create commit 'm' as a merge commit, because one of its parents is not known to git. The imported history looks like this: ... - a - b - c - m <- trunk A later 'git svn fetch' to import all branches can't rewrite the commit 'm' to add 'e' as a parent and to make it a real git merge commit, because it was already imported. That's why the imported history misses the merge and looks like this: ... - a - b - c - m <- trunk \ d - e <- branch1 Right now the only known workaround for importing 'm' as a merge is to force reimporting 'm' again from SVN, e.g. via $ git svn reset --revision $(git find-rev $c) $ git svn fetch Sadly, this is where the behavior has regressed: git svn reset doesn't invalidate the old mergeinfo cache, which is no longer valid for the reimport, which leads to 'm' beeing imprted with only 'c' as parent. As solution to this problem, this commit invalidates the mergeinfo cache to force correct recalculation of the parents. During development of this patch, several ways for invalidating the cache where considered. One of them is to use Memoize::flush_cache, which will call the CLEAR method on the underlying Memoize persistency implementation. Sadly, neither Memoize::Storable nor the newer Memoize::YAML module introduced in 68f532f4ba888 could optionally be used implement the CLEAR method, so this is not an option. Reseting the internal hash used to store the memoized values has the same problem, because it calls the non-existing CLEAR method of the underlying persistency layer, too. Considering this and taking into account the different implementations of the memoization modules, where Memoize::Storable is not in our control, implementing the missing CLEAR method is not an option, at least not if Memoize::Storable is still used. Therefore the easiest solution to clear the cache is to delete the files on disk in 'git svn reset'. Normally, deleting the files behind the back of the memoization module would be problematic, because the in-memory representation would still exist and contain wrong data. Fortunately, the memoization is active in memory only for a small portion of the code. Invalidating the cache by deleting the files on disk if it isn't active should be safe.

This is closer to how SVN 1.7's canonicalization behaves. Doing it with 1.6 lets us chase down some problems caused by more effective canonicalization without having to deal with all the other 1.7 issues on top of that. * Remote URLs have to be canonicalized otherwise Git::SVN->find_existing_remote will think they're different. * The SVN remote is now written to the git config canonicalized.

2012-06-10git-svn: use YAML format for mergeinfo cache when possibleLibravatar Jonathan Nieder2-0/+94
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).

For simplicity, we install this as a module in the standard search path, just like the existing Git and Git::I18N modules. In the process, add a manpage explaining its interface and that it is not likely to be useful for other projects to avoid confusion.

2012-03-16perl/Makefile: install Git::I18N under NO_PERL_MAKEMAKERLibravatar Ævar Arnfjörð Bjarmason1-2/+5
When I added the i18n infrastructure in v1.7.8-rc2-1-g5e9637c I forgot to install Git::I18N also when NO_PERL_MAKEMAKER=YesPlease was set. Change the generation of the fallback perl.mak file to do that. Now Git/I18N.pm is installed alongside Git.pm in such a way that anything that uses GITPERLLIB will find it. Reported-by: Tom G.

2012-03-10Git::I18N: compatibility with perl <5.8.3Libravatar Ævar Arnfjörð Bjarmason1-1/+10
Change the Exporter invocation in Git::I18N to be compatible with 5.8.0 to 5.8.2 inclusive. Before Exporter 5.57 (released with 5.8.3) Exporter didn't export the 'import' subroutine.
