68f532f4ba git-svn: use YAML format for mergeinfo cache when possible
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).

9f7ad1479d git-svn: make Git::SVN::RA a separate file
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.)

72827aa468 git-svn: rename SVN::Git::* packages to Git::SVN::*
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.

c102f4cf72 git-svn: move Git::SVN::Prompt into its own file
git-svn.perl is very long (around 6500 lines) and although it is
nicely split into modules, some new readers do not even notice --- it
is too distracting to see all this functionality collected in a single
file.

Splitting it into multiple files would make it easier for people
to read individual modules straight through and to experiment with
components separately.

Let's start with Git::SVN::Prompt.  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.

6ade9bdada git-svn: ignore SIGPIPE
In HTTP with keep-alive it's not uncommon for the client to notice that
the server decided to stop maintaining the current connection only when
sending a new request.  This naturally results in -EPIPE and possibly
SIGPIPE.

The subversion library itself makes no provision for SIGPIPE.  Some
combinations of the underlying libraries do (typically SIG_IGN-ing it),
some don't.

Presumably for that reason all subversion commands set SIGPIPE to
SIG_IGN early in their main()-s.

So should we.

This, together with the previous patch, fixes the notorious "git-svn
died of signal 13" problem (see e.g.
http://thread.gmane.org/gmane.comp.version-control.git/134936).

037a98cd3f git-svn: use POSIX::sigprocmask to block signals
In order to maintain consistency of the database mapping svn revision
numbers to git commit ids, rev_map_set() defers signal processing until
it's finished with an append transaction.[*]

The conventional way to achieve this is through sigprocmask(), which is
available in perl in the standard POSIX module.

This is implemented by this patch.  One important consequence of it is
that the signal handlers won't be unconditionally set to SIG_DFL anymore
upon the first invocation of rev_map_set() as they used to.  As a
result, the signals ignored by git-svn parent will remain ignored;
otherwise the behavior remains the same.

This patch paves the way to ignoring SIGPIPE throughout git-svn which
will be done in the followup patch.

[*] Deferring signals is not enough to ensure the database consistency:
the program may die on SIGKILL or power loss, run out of disk space,
etc.  However that's a separate issue that this patch doesn't address.

open_or_add_dir checks to see if the directory already exists or not.
If it already exists and is not a directory, then we fail.  However,
open_or_add_dir did not previously account for the possibility that the
path did exist as a file, but is deleted in the current commit.

In order to prevent this legitimate case from failing, open_or_add_dir
needs to know what files are deleted in the current commit.

1e5814f3de git-svn: teach git-svn to populate svn:mergeinfo
Allow git-svn to populate the svn:mergeinfo property automatically in
a narrow range of circumstances. Specifically, when dcommitting a
revision with multiple parents, all but (potentially) the first of
which have been committed to SVN in the same repository as the target
of the dcommit.

In this case, the merge info is the union of that given by each of the
parents, plus all changes introduced to the first parent by the other
parents.

In all other cases where a revision to be committed has multiple
parents, cause "git svn dcommit" to raise an error rather than
completing the commit and potentially losing history information in
the upstream SVN repository.

This behavior is disabled by default, and can be enabled by setting
the svn.pushmergeinfo config option.

Similar to the 'remote.<name>.pushurl' config key for git remotes,
'pushurl' is designed to be used in cases where 'url' points to an SVN
repository via a read-only transport, to provide an alternate
read/write transport. It is assumed that both keys point to the same
repository.

The 'pushurl' key is distinct from the 'commiturl' key in that
'commiturl' is a full svn path while 'pushurl' (like 'url') is a base
path. 'commiturl' takes precendece over 'pushurl' in cases where
either might be used.

The 'pushurl' is used by git-svn's dcommit and branch commands.

"git svn mkdirs" (which creates empty directories in the current
working copy) can be very slow and is often unnecessary.  Provide a
config file option "svn-remote.<name>.automkdirs" that prevents empty
directories from being created automatically.  (They are still created
if "git svn mkdirs" is invoked explicitly.)

b1b47554ae git-log: put space after commit mark
Currently, commit marks (left, right, boundary, cherry) are output right
before the commit sha1, which makes it difficult to copy sha1s. Sample
output for "git log --oneline --cherry":

=049c269 t6007: test rev-list --cherry

Change this to

= 049c269 t6007: test rev-list --cherry

which matches exactly the current output of "git log --graph".

Leave "git rev-list" output as is (no space) so that they do not break.

Adjust "git-svn" which uses "git log --pretty=raw --boundary".

d48b284183 perl: bump the required Perl version to 5.8 from 5.6.[21]
Formalize our dependency on perl 5.8, bumped from 5.6.[12]. We already
used the three-arg form of open() which was introduced in 5.6.1, but
t/t9700/test.pl explicitly depended on 5.6.2.

However git-add--interactive.pl has been failing on the 5.6 line since
it was introduced in v1.5.0-rc0~12^2~2 back in 2006 due to this open
syntax:

    sub run_cmd_pipe {
           my $fh = undef;
           open($fh, '-|', @_) or die;
           return <$fh>;
    }

Which when executed dies on "Can't use an undefined value as
filehandle reference". Several of our tests also fail on 5.6 (even
more when compiled with NO_PERL_MAKEMAKER=1):

    t2016-checkout-patch.sh
    t3904-stash-patch.sh
    t3701-add-interactive.sh
    t7105-reset-patch.sh
    t7501-commit.sh
    t9700-perl-git.sh

Our code is bitrotting on 5.6 with no-one interested in fixing it, and
pinning us to such an ancient release of Perl is keeping us from using
useful features introduced in the 5.8 release.

The 5.6 series is now over 10 years old, and the 5.6.2 maintenance
release almost 7. 5.8 on the other hand is more than 8 years old.

All the modern Unix-like operating systems have now upgraded to it or
a later version, and 5.8 packages are available for old IRIX, AIX
Solaris and Tru64 systems.

3235b7053c git-svn: fix fetch with deleted tag
Currently git-svn assumes that two tags created from the same
revision will have the same repo url, so it uses a ref to the
tag without checking that its url matches the current url.

This causes issues when fetching an svn repo where a tag was
created, deleted, and then recreated under the following
circumstances:

- Both tags were copied from the same revision.
- Both tags had the same name.
- Both tags had different repository paths.
- [Optional] Both tags have a file with the same name but
  different content.

When all four conditions are met, a checksum mismatch error
occurs because the content of two files with the same path
differs (see t/t9155--git-svn-fetch-deleted-tag.sh):

    Checksum mismatch: ChangeLog 065854....
    expected: ce771b....
         got: 9563fd....

When only the first three conditions are met, no error occurs
but the tag in git matches the first (deleted) tag instead of
the last (most recent) tag (see
t/t9156-git-svn-fetch-deleted-tag-2.sh).

The fix is to verify that the repo url for the ref matches the
current url.  If the urls do not match, then a "tail" is grown
on the tag name by appending a dash and rechecking the new ref's
repo url until either a matching repo url is found or a new tag
is created.

181264ad59 git svn: fix dcommit to work with touched files
The dcommit command fails if an otherwise unmodified file has
been touched in the working directory:

    Cannot dcommit with a dirty index.  Commit your changes
    first, or stash them with `git stash'.

This happens because "git diff-index" reports a difference
between the index and the filesystem:

    :100644 100644 d00491...... 000000...... M      file

The fix is to run "git update-index --refresh" before
"git diff-index" as is done in git-rebase and
git-rebase--interactive before "git diff-files".

This changes dcommit to display a list of modified files before
exiting.

Also add a similar test case for "git svn rebase".

8ac3a66702 git-svn: write memoized data explicitly to avoid Storable bug
Apparently using the Storable module during global destruction is
unsafe - there is a bug which can cause segmentation faults:

  http://rt.cpan.org/Public/Bug/Display.html?id=36087
  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=482355

The persistent memoization support introduced in commit 8bff7c538
relied on global destruction to write cached data, which was leading
to segfaults in some Perl configurations.  Calling Memoize::unmemoize
in the END block forces the cache writeout to be performed earlier,
thus avoiding the bug.

b4b3360078 git-svn: strip off leading slashes on --trunk argument
The following command

 git svn clone \
	-r9500:10006 \
	svn://svn.debian.org/svn/pkg-games/packages \
	--trunk=/trunk/freedoom \
	--branches=/branches/freedoom \
	--tags=/tags/freedoom \
	freedoom.git.2009091

produces strange results:

With v1.6.3.3 (and perhaps earlier versions), this would fetch up to
and including r9978 (the last revision of the no_iwad_alternatives
branch before it was deleted), check it out, and prematurely declare
success, leaving out some commits to the trunk (r9984, r9985, r10006)
from after the branch was merged.

With v1.6.5-rc0~74 (svn: allow branches outside of refs/remotes,
2009-08-11) and later, this fetches up to and including r9978 and then
attempts a post-fetch checkout and fails.

 r9978 = 25f0920175c395f0f22f54ae7a2318147f745274
 (refs/remotes/no_iwad_alternatives)
 fatal: refs/remotes/trunk: not a valid SHA1
 update-ref refs/heads/master refs/remotes/trunk: command returned error: 128

Checking .git/config reveals

 fetch = packages//trunk/freedoom:refs/remotes/trunk

And with both 1.6.3.3 and 1.7.1, using --trunk=trunk/freedom without
the leading slash (/) works fine.

Moral: git-svn needs to scrub an initial / from $_trunk and related
arguments it receives.  Make it so.

3e18ce1ac3 git-svn: allow UUID to be manually remapped via rewriteUUID
In certain situations it may be necessary to manually remap an svn
repostitory UUID. For example:

                  o--- [git-svn clone]
                 /
[origin svn repo]
                 \
                  o--- [svnsync clone]

Imagine that only "git-svn clone" and "svnsync clone" are made available
to external users. Furthur, "git-svn clone" contains only trunk, and for
reasons unknown, "svnsync clone" is missing the revision properties that
normally provide the origin svn repo's UUID.

A git user who has cloned the "git-svn clone" repo now wishes to use
git-svn to pull in the missing branches from the "synsync clone" repo.
In order for git-svn to get the history correct for those branches,
it needs to know the origin svn repo's UUID. Hence rewriteUUID.

Change git-svn to warn and continue when merge-base fails while processing svn
merge tickets.

merge-base can fail when a partial branch is created and merged back to trunk
in svn, because it cannot find a common ancestor between the partial branch and
trunk.

1cef6500a9 git-svn: ignore changeless commits when checking for a cherry-pick
Update git-svn to ignore commits that do not change the tree when it is
deciding if an svn merge ticket represents a real branch merge or just a
cherry-pick.

Consider the following integration model in the svn repository:

   F---G  branch1
  /     \
 D  tag1 \   E  tag2
/         \ /
A---B      C  trunk

branch1 is merged to trunk in commit C.

With this patch, git-svn will correctly identify branch1 as a proper merge
parent, instead of incorrectly ignoring it as a cherry-pick.

150d38c4f3 git svn: branch/tag commands detect username in URLs
svn+ssh:// repositories often have userinfo embedded in the URL
which were stripped out of the "git-svn-id:" trailers.  Since
the SVN::Client::copy function takes userinfo into account when
matching URLs for SVN repositories, we need to retrieve the full
URL with embedded userinfo in it to avoid mismatched URLs.

063681d72e git-svn: Remove obsolete MAXPARENT check
Change git-svn not to impose a limit of 16 parents on a merge.

This limit in git-svn artificially prevents cloning svn repositories
that contain commits with more than 16 merge parents.

The limit was removed from builtin-commit-tree.c for git v1.6.0 in commit
ef98c5cafb, so there is no need to check for it
it in git-svn.

7a955a5365 git-svn: detect cherry-picks correctly.
The old function was incorrect; in some instances it marks a cherry picked
range as a merged branch (because of an incorrect assumption that
'rev-list COMMIT --not RANGE' would work).  This is replaced with a
function which should detect them correctly, memoized to limit the expense
of dealing with branches with many cherry picks to one 'merge-base' call
per merge, per branch which used cherry picking.

ea020cbd6a git-svn: exclude already merged tips using one rev-list call
The old function would have to check all mentioned merge tips, every time
that the mergeinfo ticket changed.  This involved 1-2 rev-list operation
for each listed mergeinfo line.  If there are a lot of feature branches
being merged into a trunk, this makes for a very expensive operation for
detecting the new parents on every merge.

This new version first uses a single 'rev-list' to figure out which commit
ranges are already reachable from the parents.  This is used to eliminate
the already merged branches from the list.

33973a5b17 git-svn: fix some mistakes with interpreting SVN mergeinfo commit ranges
SVN's list of commit ranges in mergeinfo tickets is inclusive, whereas
git commit ranges are exclusive on the left hand side.  Also, the end
points of the commit ranges may not exist; they simply delineate
ranges of commits which may or may not exist.  Fix these two mistakes.

7d944c3399 git-svn: memoize conversion of SVN merge ticket info to git commit ranges
Each time the svn mergeinfo ticket changes, we look it up in the rev_map;
when there are a lot of merged branches, this will result in many repeated
lookups of the same information for subsequent commits.  Arrange the slow
part of the function so that it may be memoized, and memoize it.  The more
expensive revision walking operation can be memoized separately.

577e9fcad2 git svn: fix --revision when fetching deleted paths
When using the -r/--revision argument to fetch deleted history,
calling SVN::Ra::get_log() from an SVN::Ra object initialized
to track the deleted URL will fail.

This regression was introduced in:
  commit 4aacaeb3dc
  "fix shallow clone when upstream revision is too new"

We now ignore errors from SVN::Ra::get_log() here because using
--revision will always override the value of $head here if
(and only if) we're tracking deleted directories.

6111b93499 git svn: attempt to create empty dirs on clone+rebase
We parse unhandled.log files for empty_dir statements and make a
best effort attempt to recreate empty directories on fresh
clones and rebase.  This should cover the majority of cases
where users work off a single branch or for projects where
branches do not differ in empty directories.

Since this cannot affect "normal" git commands like "checkout"
or "reset", so users switching between branches in a single
working directory should use the new "git svn mkdirs" command
after switching branches.

1a30582b43 git svn: read global+system config for clone+init
Since $GIT_DIR does not exist when initializing new repositories,
we can follow back to the global and system config files for

The logic for this was originally introduced when
$GIT_DIR/config was the only config file git could read (back
when "git config" was "git repo-config"), so the function is
renamed to "read_git_config" instead of "read_repo_config".

753dc384dc git svn: handle SVN merges from revisions past the tip of the branch
When recording the revisions that it has merged, SVN sets the top
revision to be the latest revision in the repository, which is not
necessarily a revision on the branch that is being merged from.  When
it is not on the branch, git-svn fails to add the extra parent to
represent the merge because it relies on finding the commit on the
branch that corresponds to the top of the SVN merge range.

In order to correctly handle this case, we look for the maximum
revision less than or equal to the top of the SVN merge range that is
actually on the branch being merged from.

[ew: This includes the following (squashed) commit to prevent
     errors during bisect:]

    git-svn: add (failing) test for SVN 1.5+ merge with intervening commit

    This test exposes a bug in git-svn's handling of SVN 1.5+ mergeinfo
    properties.  The problematic case is when there is some commit on an
    unrelated branch after the last commit on the merged-from branch.
    When SVN records the mergeinfo property, it records the latest
    revision in the whole repository, which, in the problematic case, is
    not on the branch it is merging from.

    To trigger the git-svn bug, we modify t9151 to include two SVN merges,
    the second of which has an intervening commit.  The SVN dump was
    generated using SVN 1.6.6 (on Debian squeeze amd64).
