2008-06-01git-svn fails in prop_walk if $self->{path} is not emptyChristian Engwer
If url://repo/trunk is the current Git branch, prop_walk strips trunk from the path name. That is useful as, for example "git svn show-ignore" should not return results like trunk/foo but foo if svn:ignore for trunk includes foo. The problem now is that prop_walk strips trunk from the path and then calls itself recursively. But now trunk is missing in the path and get_dir fails, because it is called for a non existing path. The attached patch fixed the problem, by adding the previously stipped $self->{path} in the recursive call. I tested it with my current git-svn repository for the commands show-ignore and show-external.

2008-05-28Git::cat_blob: allow using an empty blob to fix git-svn breakageJunio C Hamano
Recent "git-svn optimization" series introduced Git::cat_blob() subroutine whose interface was broken in that it returned the size of the blob but signalled an error by returning 0. You can never use an empty blob with such an interface. This fixes the interface to return a negative value to signal an error. Reported by Björn Steinbrink.

2008-05-01git-svn: Same default as cvsimport when using --use-log-authorStephen R. van den Berg
When using git-cvsimport, the author is inferred from the cvs commit, e.g. cvs commit logname is foobaruser, then the author field in git results in: Author: foobaruser <foobaruser> Which is not perfect, but perfectly acceptable given the circumstances. The default git-svn import however, results in: Author: foobaruser <foobaruser@acf43c95-373e-0410-b603-e72c3f656dc1> When using mixes of imports, from CVS and SVN into the same git repository, you'd like to harmonise the imports to the format cvsimport uses. git-svn supports an experimental option --use-log-author which currently results in the same logentry as without that option when no From: or Signed-off-by: is found in the logentry ($email currently ends up empty, and hence is generated again).

2008-04-30git-svn: detect and fail gracefully when dcommitting to a voidMatthieu Moy
The command git svn clone (URL of an empty SVN repo here) works, creates an empty git repository.

2008-03-09Fix dcommit, rebase when rewriteRoot is in useJohn Goerzen
When the rewriteRoot setting is used with git-svn, it causes the svn IDs added to commit messages to bear a different URL than is actually used to retrieve Subversion data. It is common for Subversion repositories to be available multiple ways: for instance, HTTP to the public, and svn+ssh to people with commit access. The need to switch URLs for access is fairly common as well -- perhaps someone was just given commit access. To switch URLs without having to rewrite history, one can use the old url as a rewriteRoot, and use the new one in the svn-remote url setting. This works well for svn fetching and general git commands. However, git-svn dcommit, rebase, and perhaps other commands do not work in this scenario. They scan the svn ID lines in commit messages and attempt to match them up with url lines in [svn-remote] sections in the git config. This patch allows them to match rewriteRoot options, if such options are present. Signed-off-by: John Goerzen <jgoerzen@complete.org> Acked-by: Eric Wong <normalperson@yhbt.net>

2008-02-06git-svn: improve repository URL matching when following parentsEric Wong
This way we can avoid the spawning of a new SVN::Ra session by reusing the existing one. The most problematic issue is that some svn servers disallow too many connections from a single IP, so this will allow git-svn to fetch from those repositories with a higher success rate by using fewer connections.

2008-01-12git-svn: handle leading/trailing whitespace from svnsync revpropsEric Wong
Repositories generated by svnsync cannot be relied on to have properly set revprops without newlines in UUIDs and URLs. There may be broken versions of svnsync out there that append extra newlines to UUIDs, or the revprops could've been changed by repository administrators at any time, too. At least one repository we've come across has an embedded newline erroneously set in the svnsync-uuid prop. This is bad because the trailing newline is taken as another record by the Git.pm library, and the wantarray detection causes tmp_config() to return an array with an empty-but-existing second element. We will now strip leading and trailing whitespace both before setting and after reading the uuid and url for svnsync values. We will also force tmp_config to return a single scalar when reading existing values. SVN UUIDs should never have whitespace in them, and SVN repository URLs should be URI-escaped, so neither of those values we ever see in git-svn should actually have whitespace in them.

2007-12-19git-svn: workaround a for broken symlinks in SVNEric Wong
It's possible for bad clients to commit symlinks without the 5-character "link " prefix in symlinks. So guard around this bug in SVN and make a best effort to create symlinks if the "link " prefix is missing. More information on this SVN bug is described here: http://subversion.tigris.org/issues/show_bug.cgi?id=2692 To be pedantic, there is still a corner case that neither we nor SVN can handle: If somebody made a link using a broken SVN client where "link " is the first part of its path, e.g. "link sausage", then we'd end up having a symlink which points to "sausage" because we incorrectly stripped the "link ".

We set the 6 environment variables for controlling committer/author email/name/time for every commit. We do this in the parent process to be passed to git-commit-tree, because open3() doesn't afford us the control of doing it only in the child process. This means we leave them hanging around in the main process until the next revision comes around and all 6 environment variables are overwridden again. Unfortunately, for the last commit, leaving them hanging around means the git-rebase invocation will pick it up, rewriting the rebased commit with incorrect author information. This should fix it.

2007-12-11git-svn: replace .rev_db with a more space-efficient .rev_map formatEric Wong
Migrations are done automatically on an as-needed basis when new revisions are to be fetched. Stale remote branches do not get migrated, yet. However, unless you set noMetadata or useSvkProps it's safe to just do: find $GIT_DIR/svn -name '.rev_db*' -print0 | xargs rm -f to purge all the old .rev_db files. The new format is a one-way migration and is NOT compatible with old versions of git-svn. This is the replacement for the rev_db format, which was too big and inefficient for large repositories with a lot of sparse history (mainly tags). The format is this: - 24 bytes for every record, * 4 bytes for the integer representing an SVN revision number * 20 bytes representing the sha1 of a git commit - No empty padding records like the old format - new records are written append-only since SVN revision numbers increase monotonically - lookups on SVN revision number are done via a binary search - Piping the file to xxd(1) -c24 is a good way of dumping it for viewing or editing, should the need ever arise. As with .rev_db, these files are disposable unless noMetadata or useSvmProps is set. Signed-off-by: Eric Wong <normalperson@yhbt.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
