2beec89733 git-svn: do a partial rebuild if rev_map is out-of-date
Suppose you're using git-svn to work with a certain SVN repository.
Since you don't like 'git-svn fetch' to take forever, and you don't want
to accidentally interrupt it and end up corrupting your repository, you
set up a remote Git repository to mirror the SVN repository, which does
its own 'git-svn fetch' on a cronjob; now you can 'git-fetch' from the
Git mirror into your local repository, and still dcommit to SVN when you
have changes to push.

After you do this, though, git-svn will get very confused if you ever
try to do 'git-svn fetch' in your local repository again, since its
rev_map will differ from the branch's head, and it will be unable to
fetch new commits from SVN because of the metadata conflict.  But all
the necessary metadata are there in the Git commit message; git-svn
already knows how to rebuild rev_map files that get blown away, by
using the metadata.

This patch teaches git-svn do a partial rebuild of the rev_map to
match the true state of the branch, if it ever is used to fetch again.

This will only work for projects not using either noMetadata or
useSvmProps configuration options; if you are using these options,
git-svn will fall back to the previous behaviour.

2cf3e3ac02 git-svn: match SVN 1.5 behaviour of info' on unknown item
Previously 'git svn info unknown-file' only announced its failure (in
the SVN 1.4 style, "not a versioned resource"), and exited
successfully.

It is desirable to actually exit with failure, so change the code to
exit(1) under this condition.  Since that is already halfway SVN 1.5
compatibility, also change the error output to match 1.5.

Note that reusing the escape_url() further down in Git::SVN::Ra is not

whether extending it to all schemes would break SVN access anywhere,
so I made a new one that quotes in all schemes.

711521e246 git-svn: fix dcommit to urls with embedded usernames
Don't rely on the extracted URL from working_head_info since that has the
username removed.  Instead use the $gs->full_url method (as before with
ba24e74 (git-svn: add ability to specify --commit-url for dcommit,
2008-08-07)) to give us the URL to commit to if --commit-url is not
specified.

Aditionally, since we clean usernames from URLs, checking the URL after
rebase can fail because it doesn't match the URL we used to commit; so
unconditionally provide a username-free URL for checking the result of the
refetch.

510b0945d0 git-svn: Reduce temp file usage when dealing with non-links
Currently, in sub 'close_file', git-svn creates a temporary file and
copies the contents of the blob to be written into it. This is useful
for symlinks because svn stores symlinks in the form:

link $FILE_PATH

Git creates a blob only out of '$FILE_PATH' and uses file mode to
indicate that the blob should be interpreted as a symlink.

As git-hash-object is invoked with --stdin-paths, a duplicate of the
link from svn must be created that leaves off the first five bytes,
i.e. 'link '. However, this is wholly unnecessary for normal blobs,
though, as we already have a temp file with their contents. Copying
the entire file gains nothing, and effectively requires a file to be
written twice before making it into the object db.

This patch corrects that issue, holding onto the substr-like
duplication for symlinks, but skipping it altogether for normal blobs
by reusing the existing temp file.

0b19138ba3 git-svn: Make it incrementally faster by minimizing temp files
Currently, git-svn would create a temp file on four occasions:
1. Reading a blob out of the object db
2. Creating a delta from svn
3. Hashing and writing a blob into the object db
4. Reading a blob out of the object db (in another place in code)

Any time git-svn did the above, it would dutifully create and then
delete said temp file.  Unfortunately, this means that between 2-4
temporary files are created/deleted per file 'add/modify'-ed in
svn (O(n)).  This causes significant overhead and helps the inode
counter to spin beautifully.

By its nature, git-svn is a serial beast.  Thus, reusing a temp file
does not pose significant problems.  "truncate and seek" takes much
less time than "unlink and create".  This patch centralizes the
tempfile creation and holds onto the tempfile until they are deleted
on exit.  This significantly reduces file overhead, now requiring
at most three (3) temp files per run (O(1)).

570d35c26d git-svn: Allow deep branch names by supporting multi-globs
Some repositories use a deep branching strategy, such as:

    branches/1.0/1.0.rc1
    branches/1.0/1.0.rc2
    branches/1.0/1.0.rtm
    branches/1.0/1.0.gold

Only allowing a single glob stiffles this.

This change allows for a single glob 'set' to accept this deep
branching strategy.

The ref glob depth must match the branch glob depth.  When using
the -b or -t options for init or clone, this is automatically
done.

For example, using the above branches:

  svn-remote.svn.branches = branches/*/*:refs/remote/*/*

gives the following branch names:

  1.0/1.0.rc1
  1.0/1.0.rc2
  1.0/1.0.rtm
  1.0/1.0.gold

ba24e7457a git-svn: add ability to specify --commit-url for dcommit
This allows one to use public svn:// URLs for fetch and
svn+ssh:// URLs for committing (without using the complicated
rewriteRoot option, reimporting or git-filter-branch).

Using this can also help avoid unnecessary server
authentication/encryption overhead on busy SVN servers.

Along with the new --revision option, this can also be allowed
to override the branch detection in dcommit, too.  This is
potentially dangerous and not recommended!  (And also purposely
undocumented, but the loaded gun is there in case somebody
wants to make it safe).

611921654f git-svn: Abort with an error if 'fetch' parameter is invalid.
Previously, if a config entry looked like this:

         svn-remote.svn.fetch=:refs/heads/whatever

git-svn would silently do nothing if you asked it to "git svn fetch", and
give a strange error if asked to "git svn dcommit".  What it really wants is
a line that looks like this:

	svn-remote.svn.fetch=:refs/remotes/whatever

So we should simply abort if we get the wrong thing.

On the other hand, there's actually no good reason for git-svn to enforce
using the refs/remotes namespace, but the code seems to have hardcoded this
in several places and I'm not brave enough to try to fix it all right now.

29c70e0b3e git-svn: avoid filling up the disk with temp files.
Commit ffe256f9ba ("git-svn: Speed up fetch")
introduced changes that create a temporary file for each object fetched by
svn.  These files should be deleted automatically, but perl apparently
doesn't do this until the process exits (or perhaps when its garbage
collector runs).

This means that on a large fetch, especially with lots of branches, we
sometimes fill up /tmp completely, which prevents the next temp file from
being written completely.  This is aggravated by the fact that a new temp
file is created for each updated file, even if that update produces a file
identical to one already in git.  Thus, it can happen even if there's lots
of disk space to store the finished repository.

We weren't adequately checking for write errors, so this would result in an
invalid file getting committed, which caused git-svn to fail later with an
invalid checksum.

This patch adds a check to syswrite() so similar problems don't lead to
corruption in the future.  It also unlink()'s each temp file explicitly
when we're done with it, so the disk doesn't need to fill up.

74b1e12357 git-svn: make rebuild respect rewriteRoot option
Suppose someone fetches git-svn-ified commits from another repo and then
attempts to use 'git-svn init --rewrite-root=foo bar'. Using git svn rebase
after that will fail badly:

 * For each commit tried by working_head_info, rebuild is called indirectly.
 * rebuild will iterate over all commits and skip all of them because the
   URL does not match. Because of that no rev_map file is generated at all.
 * Thus, rebuild will run once for every commit. This takes ages.
 * In the end there still isn't any rev_map file and thus working_head_info
   fails.

Addressing this behaviour fixes an apparently not too uncommon problem with
providing git-svn mirrors of Subversion repositories. Some repositories are
accessed using different URLs depending on whether the user has push
privileges or not. In the latter case, an anonymous URL is often used that
differs from the push URL. Providing a mirror that is usable in both cases
becomes a lot more possible with this change.

328eb9b32f git-svn: don't append extra newlines at the end of commit messages.
In git, all commits end in exactly one newline character.  In svn, commits
end in zero or more newlines.  Thus, when importing commits from svn into
git, git-svn always appends two extra newlines to ensure that the
git-svn-id: line is separated from the main commit message by at least one
blank line.

Combined with the terminating newline that's always present in svn commits
produced by git, you usually end up with two blank lines instead of one
between the commit message and git-svn-id: line, which is undesirable.

Instead, let's remove all trailing whitespace from the git commit on the way
through to svn.

b7166cce8c git-svn fails in prop_walk if $self->{path} is not empty
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.

abfa533dea git-svn: Same default as cvsimport when using --use-log-author
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).

This patches harmonises the result with cvsimport, and makes
git-svn --use-log-author produce:

Author: foobaruser <foobaruser>

0bb91d9a62 Fix dcommit, rebase when rewriteRoot is in use
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.

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.

This sometimes showed up as a new (and redundant)
[svn-remote "$parent_refname"] entry in $GIT_DIR/svn/.metadata.

98fa5b6851 git-svn: handle leading/trailing whitespace from svnsync revprops
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.

Thanks to Dennis Schridde for the bug report and Junio for
helping diagnose this.

321b1842dc git-svn: unlink index files that were globbed, too
commit 3157dd9e89 (git-svn: unlink
internal index files after operations) introduced unlinking
index files after fetching.  However, this missed indices for
refs that were created by globbing branches and tags.  This will
track all refs we ever touch during a fetch and unlink them at
exit time.

7fc35e0e94 git-svn: workaround a for broken symlinks in SVN
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 ".
Hopefully this hasn't happened in practice, but if it has,
it's not our fault SVN is broken :)

Thanks to Benoit Sigoure and Sverre Johansen for reporting
and feedback.

ad94802a7b git-svn: avoid leaving leftover committer/author info in rebase
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.

12a6d752fb git-svn: handle our top-level path being deleted and later re-added
Previously, git-svn would ignore cases where the path we're
tracking is removed from the repository.  This was to prevent
heads with follow-parent from ending up with a tree full of
empty revisions (and thus breaking rename detection).

The previous behavior is fine until the path we're tracking
is re-added later on, leading to the old files being merged
in with the new files in the directory (because the old
files were never marked as deleted)

We will now only remove all the old files locally that were
deleted remotely iff we detect the directory we're in is being
created from scratch.

Thanks for Marcus D. Hanwell for the bug report and
Peter Baumann for the analysis.

cd459e3ffa git-svn: get color config from --get-colorbool
git-config recently learned a --get-colorbool option. By

Specifically, this fixes the case where "color.diff = true"

66ab84b99c git-svn: reinstate old rev_db optimization in new rev_map
This reinstates an old optimization in .rev_db which
stored the highest revision number we scanned, allowing
us to avoid scanning the SVN log for those revisions
again in a subsequent invocation.

This means the last 24-byte record in a .rev_map file
can be a 4-byte SVN revision number with 20-bytes of
zeroes representing a non-existent commit.  This record
can and will be overwritten when a new commit iff
the commit is all zeroes.

060610c572 git-svn: replace .rev_db with a more space-efficient .rev_map format
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.

2d87979215 git-svn: add a show-externals command.
show-externals can be used by scripts to provide svn:externals-like
functionality.  For example, a script can list all of the externals and then
use check out the listed URLs at the appropriate paths, similar to what the svn
client does.  Said script (or perhaps git-svn itself, in the future) could
simply invoke svn export on the paths, or it could go one further, using
git-svn clone and even git-submodule together to better integrate externals
checkouts.

The implementation is shamelessly copied from show-ignores.  A more general
command to list user-specified properties is probably a better idea.
