Michael J Gruber 9963e025e8 git-svn: Fix git svn log --show-commit
git svn log --show-commit had no tests and, consequently, no attention
by the author of

b1b4755 (git-log: put space after commit mark, 2011-03-10)

who kept git svn log working only without --show-commit.

Introduce a test and fix it.

Alejandro R. Sedeño 12a296bca3 git-svn: Add a svn-remote.<name>.pushurl config key
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.

Michael Haggerty 55f9d7a75c git-svn: add an option to skip the creation of empty directories
"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.)

Michael J Gruber 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".

  perl: bump the required Perl version to 5.8 from 5.6.[21]
2010-10-26 21:57:31 -07:00
Ævar Arnfjörð Bjarmason 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.

David D. Kilzer 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.

David D. Kilzer 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".

Sergey Vlasov 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.

Jonathan Nieder 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.

spaces. As GIT_SSH will not work if it contains quotes, it is safe to

Jay Soffian 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.

When constructing a destination URL, use the property 'commiturl' if it
is specified in the configuration file; otherwise take 'url' as usual.
This accommodates the scenario where a user only wants to involve the
writable repository in operations performing a commit and defaults
everything else to a read-only URL.

Igor Mironov a83b91e724 git-svn: fix mismatched src/dst errors for branch/tag
This fixes the following issue:

$ git svn branch -t --username=svnuser \
  --commit-url=https://myproj.domain.com/svn mytag
Copying http://myproj.domain.com/svn/trunk at r26 to
https://myproj.domain.com/svn/tags/mytag...

Trying to use an unsupported feature: Source and dest appear not to be
in the same repository (src: 'http://myproj.domain.com/svn/trunk';
dst: 'https://myproj.domain.com/svn/tags/mytag')

Andrew Myrick 41c01693ac git-svn: handle merge-base failures
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.

Andrew Myrick 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.

Eric Wong 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.

Eric Wong 0fe19753f2 git svn: lookup new parents correctly from svn:mergeinfo
This appears to be a trivial case where array indices were being

Andrew Myrick 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.

Sam Vilain 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.

Sam Vilain 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.

Sam Vilain 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.

Sam Vilain 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.

[ew: changed "next" to "return" for function exit]
