Johan Herland fe191fcaa5 Git 2.0: git svn: Set default --prefix='origin/' if --prefix is not given
git-svn by default puts its Subversion-tracking refs directly in
refs/remotes/*. This runs counter to Git's convention of using
refs/remotes/$remote/* for storing remote-tracking branches.

Furthermore, combining git-svn with regular git remotes run the risk of
clobbering refs under refs/remotes (e.g. if you have a git remote
called "tags" with a "v1" branch, it will overlap with the git-svn's
tracking branch for the "v1" tag from Subversion.

Even though the git-svn refs stored in refs/remotes/* are not "proper"
remote-tracking branches (since they are not covered by a proper git
remote's refspec), they clearly represent a similar concept, and would
benefit from following the same convention.

For example, if git-svn tracks Subversion branch "foo" at
refs/remotes/foo, and you create a local branch refs/heads/foo to add
some commits to be pushed back to Subversion (using "git svn dcommit),
then it is clearly unhelpful of Git to throw

  warning: refname 'foo' is ambiguous.

every time you checkout, rebase, or otherwise interact with the branch.

The existing workaround for this is to supply the --prefix=quux/ to
git svn init/clone, so that git-svn's tracking branches end up in
refs/remotes/quux/* instead of refs/remotes/*. However, encouraging
users to specify --prefix to work around a design flaw in git-svn is
suboptimal, and not a long term solution to the problem. Instead,
git-svn should default to use a non-empty prefix that saves
unsuspecting users from the inconveniences described above.

This patch will only affect newly created git-svn setups, as the
--prefix option only applies to git svn init (and git svn clone).
Existing git-svn setups will continue with their existing (lack of)
prefix. Also, if anyone somehow prefers git-svn's old layout, they
can recreate that by explicitly passing an empty prefix (--prefix "")
on the git svn init/clone command line.

The patch changes the default value for --prefix from "" to "origin/",
updates the git-svn manual page, and fixes the fallout in the git-svn
testcases.

(Note that this patch might be easier to review using the --word-diff
and --word-diff-regex=. diff options.)

Jonathan Nieder 44bc5ac71f svn test: escape peg revision separator using empty peg rev
This test script uses "svn cp" to create a branch with an @-sign in
its name:

	svn cp "pr ject/trunk" "pr ject/branches/not-a@{0}reflog"

That sets up for later tests that fetch the branch and check that git
svn mangles the refname appropriately.

Unfortunately, modern svn versions interpret path arguments with an
@-sign as an example of path@revision syntax (which pegs a path to a
particular revision) and truncate the path or error out with message
"svn: E205000: Syntax error parsing peg revision '{0}reflog'".

When using subversion 1.6.x, escaping the @ sign as %40 avoids trouble
(see 08fd28bb, 2010-07-08).  Newer versions are stricter:

	$ svn cp "$repo/pr ject/trunk" "$repo/pr ject/branches/not-a%40{reflog}"
	svn: E205000: Syntax error parsing peg revision '%7B0%7Dreflog'

The recommended method for escaping a literal @ sign in a path passed
to subversion is to add an empty peg revision at the end of the path
("branches/not-a@{0}reflog@").  Do that.

Pre-1.6.12 versions of Subversion probably treat the trailing @ as
another literal @-sign (svn issue 3651).  Luckily ever since
v1.8.0-rc0~155^2~7 (t9118: workaround inconsistency between SVN
versions, 2012-07-28) the test can survive that.

Tested with Debian Subversion 1.6.12dfsg-6 and 1.7.5-1 and r1395837
of Subversion trunk (1.8.x).

Michael G. Schwern dad9090f89 t9118: workaround inconsistency between SVN versions
SVN 1.7 will truncate "not-a%40{0}" to just "not-a".

Rather than guess what SVN is going to do for each version, make the test use
the branch name that was actually created.

Jonathan Nieder 4ecb79386d t9118 (git-svn): prevent early failure from taking down later tests
When test #2 fails, the cwd is project/, causing all the
remaining tests in the same script to get confused and fail.

So in the spirit of v1.7.1.1~53^2~10 (t5550-http-fetch: Use subshell
for repository operations, 2010-04-17), use a subshell for svn
working copy operations.  This way, the cwd will reliably return
to the top of the trash directory and later tests can still be run
when a command has failed.

Michael J Gruber 08fd28bb08 t9118: avoid PEG revision identifier in tests
@ is SVN's identifier for PEG revisions. But SVN's treatment of PEG
identifiers in copy target URLs changed in r954995/r952973, i.e. between
1.6.11 and 1.6.12. They get eaten now (which is considered the right
way).

Therefore, avoid the @ in the tests with funky branch names.

Torsten Schmutzler 73d419558d git-svn: mangle refnames forbidden in git

cannot be used as refnames for git.  Some are
legal branchnames in subversion however.
Mangle the not yet handled cases.

Eygene Ryabinkin da083d688e git-svn testsuite: use standard configuration for Subversion tools
I have tweaked configuration in my ~/.subversion directory, namely I am
running auto-properties and automatically adding '$Id$' expansion to
every file.  This choke the last test named 'proplist' from
t9101-git-svn-props.sh, because one more property, svn:keywords is
automatically added.

I had just wrapped svn invocation with the svn_cmd that specifies empty
directory via --config-dir argument.  Since the latter is the global
option, it should be recognized by all svn subcommands, so no
regressions will be introduced.

Now svn_cmd is used everywhere, not just in the failed test module: this
should guard us from the future clashes with user-defined configuration
tweaks.

Eric Wong f4392df485 git-svn: fix handling of even funkier branch names
Apparently do_switch() tolerates the lack of escaping in less
funky branch names.  For the really strange and scary ones, we
need to escape them properly.  It strangely maintains compatible
with the existing handling of branch names with spaces and
exclamation marks.

Bryan Donlan f69e836fab Fix tests breaking when checkout path contains shell metacharacters
This fixes the remainder of the issues where the test script itself is at
fault for failing when the git checkout path contains whitespace or other
shell metacharacters.

The majority of git svn tests used the idiom

  test_expect_success "title" "test script using $svnrepo"

These were changed to have the test script in single-quotes:

  test_expect_success "title" 'test script using "$svnrepo"'

which unfortunately makes the patch appear larger than it really is.

One consequence of this change is that in the verbose test output the
value of $svnrepo (and in some cases other variables, too) is no
longer expanded, i.e. previously we saw

  * expecting success:
	test script using /path/to/git/t/trash/svnrepo

but now it is:

  * expecting success:
	test script using "$svnrepo"

Eric Wong cfbe7ab333 git-svn: support for funky branch and project names over HTTP(S)
SVN requires that paths be URI-escaped for HTTP(S) repositories.
file:// and svn:// repositories do not need these rules.

Additionally, accessing individual paths inside repositories
(check_path() and get_log() do NOT require escapes to function
and in fact it breaks things).
