b8c78e2a9d git svn: work around SVN 1.7 mishandling of svn:special changes
Subversion represents symlinks as ordinary files with content starting
with "link " and the svn:special property set to "*".  Thus a file can
switch between being a symlink and a non-symlink simply by toggling
its svn:special property, and new checkouts will automatically write a
file of the appropriate type.  Likewise, in subversion 1.6 and older,
running "svn update" would notice changes in filetype and update the
working copy appropriately.

Starting in subversion 1.7 (issue 4091), changes to the svn:special
property trip an assertion instead:

	$ svn up svn-tree
	Updating 'svn-tree':
	svn: E235000: In file 'subversion/libsvn_wc/update_editor.c' \
	line 1583: assertion failed (action == svn_wc_conflict_action_edit \
	|| action == svn_wc_conflict_action_delete || action == \
	svn_wc_conflict_action_replace)

Revisions prepared with ordinary svn commands ("svn add" and not "svn
propset") don't trip this because they represent these filetype
changes using a replace operation, which is approximately equivalent
to removal followed by adding a new file and works fine.  Follow suit.

Noticed using t9100.  After this change, git-svn's file-to-symlink
changes are sent in a format that modern "svn update" can handle and
tests t9100.11-13 pass again.

dc01f880a5 git-svn: keep leading slash when canonicalizing paths (fallback case)
Subversion's svn_dirent_canonicalize() and svn_path_canonicalize()
APIs keep a leading slash in the return value if one was present on
the argument, which can be useful since it allows relative and
absolute paths to be distinguished.

When git-svn's canonicalize_path() learned to use these functions if
available, its semantics changed in the corresponding way.  Some new
callers rely on the leading slash --- for example, if the slash is
stripped out then _canonicalize_url_ourselves() will transform
"proto://host/path/to/resource" to "proto://hostpath/to/resource".

Unfortunately the fallback _canonicalize_path_ourselves(), used when
the appropriate SVN APIs are not usable, still follows the old
semantics, so if that code path is exercised then it breaks.  Fix it
to follow the new convention.

Noticed by forcing the fallback on and running tests.  Without this
patch, t9101.4 fails:

 Bad URL passed to RA layer: Unable to open an ra_local session to \
 URL: Local URL 'file://homejrnsrcgit-scratch/t/trash%20directory.\
 t9101-git-svn-props/svnrepo' contains unsupported hostname at \
 /home/jrn/src/git-scratch/perl/blib/lib/Git/SVN.pm line 148

With it, the git-svn tests pass again.

9478b11968 Make git-svn branch patterns match complete URL
When using the {word,[...]} style of configuration for tags and branches,
it appears the intent is to only match whole path parts, since the words
in the {} pattern are meta-character quoted.

When the pattern word appears in the beginning or middle of the url,
it's matched completely, since the left side, pattern, and (non-empty)
right side are joined together with path separators.

However, when the pattern word appears at the end of the URL, the
right side is an empty pattern, and the resulting regex matches
more than just the specified pattern.

For example, if you specify something along the lines of

    branches = branches/project/{release_1,release_2}

and your repository also contains "branches/project/release_1_2", you
will also get the release_1_2 branch.  By restricting the match regex
with anchors, this is avoided.

f271fad266 git-svn.perl: consider all ranges for a given merge, instead of only tip-by-tip
Consider the case where you have trunk, branch1 of trunk, and branch2 of
branch1.  trunk is merged back into branch2, and then branch2 is
reintegrated into trunk.  The merge of branch2 into trunk will have
svn:mergeinfo property references to both branch1 and branch2.  When
git-svn fetches the commit that merges branch2 (check_cherry_pick),
it is necessary to eliminate the merged contents of branch1 as well as
branch2, or else the merge will be incorrectly ignored as a cherry-pick.

61b472ed8b git svn: reset invalidates the memoized mergeinfo caches
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'.

This memoization can cause problems, e.g consider the following case:

SVN repo:

  ... - a - b - c - m  <- trunk
          \        /
            d  -  e    <- branch1

The Git import of the above repo is at commit 'a' and doesn't know about
the branch1. In case of an 'git svn rebase', only the trunk of the
SVN repo is imported. During the creation of the git commit 'm', git svn
uses the svn:mergeinfo property and tries to find the corresponding git
commit 'e' to create 'm' with 'c' and 'e' as parents. But git svn rebase
only imports the current branch so commit 'e' is not imported.
Therefore git svn fails to create commit 'm' as a merge commit, because one
of its parents is not known to git. The imported history looks like this:

  ... - a - b - c - m  <- trunk

A later 'git svn fetch' to import all branches can't rewrite the commit 'm'
to add 'e' as a parent and to make it a real git merge commit, because it
was already imported.

That's why the imported history misses the merge and looks like this:

  ... - a - b - c - m  <- trunk
          \
            d  -  e    <- branch1

Right now the only known workaround for importing 'm' as a merge is to
force reimporting 'm' again from SVN, e.g. via

  $ git svn reset --revision $(git find-rev $c)
  $ git svn fetch

Sadly, this is where the behavior has regressed: git svn reset doesn't
invalidate the old mergeinfo cache, which is no longer valid for the
reimport, which leads to 'm' beeing imprted with only 'c' as parent.

As solution to this problem, this commit invalidates the mergeinfo cache
to force correct recalculation of the parents.

During development of this patch, several ways for invalidating the cache
where considered. One of them is to use Memoize::flush_cache, which will
call the CLEAR method on the underlying Memoize persistency implementation.
Sadly, neither Memoize::Storable nor the newer Memoize::YAML module
introduced in 68f532f4ba could optionally be used implement the
CLEAR method, so this is not an option.

Reseting the internal hash used to store the memoized values has the same
problem, because it calls the non-existing CLEAR method of the
underlying persistency layer, too.

Considering this and taking into account the different implementations
of the memoization modules, where Memoize::Storable is not in our control,
implementing the missing CLEAR method is not an option, at least not if
Memoize::Storable is still used.

Therefore the easiest solution to clear the cache is to delete the files
on disk in 'git svn reset'. Normally, deleting the files behind the back
of the memoization module would be problematic, because the in-memory
representation would still exist and contain wrong data. Fortunately, the
memoization is active in memory only for a small portion of the code.
Invalidating the cache by deleting the files on disk if it isn't active
should be safe.

705b49cb81 git-svn: canonicalize newly-minted URLs
Go through all the spots that use the new add_path_to_url() to
make a new URL and canonicalize them.

* copyfrom_path has to be canonicalized else find_parent_branch
  will get confused

* due to the `canonicalize_url($full_url) ne $full_url)` line of
  logic in gs_do_switch(), $full_url is left alone until after.

At this point SVN 1.7 passes except for 3 tests in
t9100-git-svn-basic.sh that look like an SVN bug to do with
symlinks.

93c3fcbe4d git-svn: attempt to mimic SVN 1.7 URL canonicalization
Previously, our URL canonicalization didn't do much of anything.
Now it actually escapes and collapses slashes.  This is mostly a cut & paste
of escape_url from git-svn.

This is closer to how SVN 1.7's canonicalization behaves.  Doing it with
1.6 lets us chase down some problems caused by more effective canonicalization
without having to deal with all the other 1.7 issues on top of that.

* Remote URLs have to be canonicalized otherwise Git::SVN->find_existing_remote
  will think they're different.

* The SVN remote is now written to the git config canonicalized.  That
  should be ok.  Adjust a test to account for that.

SVN changed its path canonicalization API between 1.6 and 1.7.

http://svnbook.red-bean.com/en/1.7/svn.developer.usingapi.html#svn.developer.usingapi.urlpath

The SVN API does not accept foo/.. but it also doesn't canonicalize
it.  We have to do it ourselves.

    my $path2 = 'bar';
    my $path = $path1 . '/' . $path2;

creating 'foo//bar'.

Could have used File::Spec, but I'm shying away from it due to SVN

d22e567770 perl/Makefile.PL: warn about duplicate module list in perl/Makefile
Adding or removing a module requires modifying both files to support
builds with and without MakeMaker.  Add a comment to remind patch
authors and reviewers at the crucial moment.

Longer term, it would be nicer to maintain a single list, perhaps in a
separate file used by both build systems.

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

(Documenting or moving functions that do not fit that pattern is left
as an exercise to the interested reader.)

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.

5e9637c629 i18n: add infrastructure for translating Git with gettext
Change the skeleton implementation of i18n in Git to one that can show
localized strings to users for our C, Shell and Perl programs using
either GNU libintl or the Solaris gettext implementation.

This new internationalization support is enabled by default. If
gettext isn't available, or if Git is compiled with
NO_GETTEXT=YesPlease, Git falls back on its current behavior of
showing interface messages in English. When using the autoconf script
we'll auto-detect if the gettext libraries are installed and act
appropriately.

This change is somewhat large because as well as adding a C, Shell and
Perl i18n interface we're adding a lot of tests for them, and for
those tests to work we need a skeleton PO file to actually test
translations. A minimal Icelandic translation is included for this
purpose. Icelandic includes multi-byte characters which makes it easy
to test various edge cases, and it's a language I happen to
understand.

The rest of the commit message goes into detail about various
sub-parts of this commit.

= Installation

Gettext .mo files will be installed and looked for in the standard
$(prefix)/share/locale path. GIT_TEXTDOMAINDIR can also be set to
override that, but that's only intended to be used to test Git itself.

= Perl

Perl code that's to be localized should use the new Git::I18n
module. It imports a __ function into the caller's package by default.

Instead of using the high level Locale::TextDomain interface I've
opted to use the low-level (equivalent to the C interface)
Locale::Messages module, which Locale::TextDomain itself uses.

Locale::TextDomain does a lot of redundant work we don't need, and
some of it would potentially introduce bugs. It tries to set the
$TEXTDOMAIN based on package of the caller, and has its own
hardcoded paths where it'll search for messages.

I found it easier just to completely avoid it rather than try to
circumvent its behavior. In any case, this is an issue wholly
internal Git::I18N. Its guts can be changed later if that's deemed
necessary.

See <AANLkTilYD_NyIZMyj9dHtVk-ylVBfvyxpCC7982LWnVd@mail.gmail.com> for
a further elaboration on this topic.

= Shell

Shell code that's to be localized should use the git-sh-i18n
library. It's basically just a wrapper for the system's gettext.sh.

If gettext.sh isn't available we'll fall back on gettext(1) if it's
available. The latter is available without the former on Solaris,
which has its own non-GNU gettext implementation. We also need to
emulate eval_gettext() there.

If neither are present we'll use a dumb printf(1) fall-through
wrapper.

= About libcharset.h and langinfo.h

We use libcharset to query the character set of the current locale if
it's available. I.e. we'll use it instead of nl_langinfo if
HAVE_LIBCHARSET_H is set.

The GNU gettext manual recommends using langinfo.h's
nl_langinfo(CODESET) to acquire the current character set, but on
systems that have libcharset.h's locale_charset() using the latter is
either saner, or the only option on those systems.

GNU and Solaris have a nl_langinfo(CODESET), FreeBSD can use either,
but MinGW and some others need to use libcharset.h's locale_charset()
instead.

48d9e6ae4b perl: command_bidi_pipe() method should set-up git environmens
When command_input_pipe and command_output_pipe are used as a
method of a Git::repository instance, they eventually call into
_cmd_exec method that sets up the execution environment such as
GIT_DIR, GIT_WORK_TREE environment variables and the current
working directory in the child process that interacts with the
repository.

command_bidi_pipe however didn't expect to be called as such, and
lacked all these set-up.  Because of this, a program that did this
did not work as expected:

    my $repo = Git->repository(Directory => '/some/where/else');
    my ($pid, $in, $out, $ctx) =
    $repo->command_bidi_pipe(qw(hash-object -w --stdin-paths));

This patch refactors the _cmd_exec into _setup_git_cmd_env that
sets up the execution environment, and makes _cmd_exec and
command_bidi_pipe to use it.

Note that unlike _cmd_exec that execv's a git command as an
external process, command_bidi_pipe is called from the main line
of control, and the execution environment needs to be restored
after open2() does its magic.

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.

Change the perl Makefile to work around this by explicitly unsetting
INSTALL_BASE.

INSTALL_BASE is set in PERL_MM_OPT by e.g. the popular local::lib
package, from its documentation:

    eval $(perl -I$HOME/perl5/lib/perl5 -Mlocal::lib 2>/dev/null)

Many other environments might also have set PERL_MM_OPT before
building Git. This change enables us to build in these environments.

402e139c7e git-svn: support fetch with autocrlf on
Before commit d3c9634e, performing a "git svn rebase" that fetched a
change containing CRLFs corrupted the git-svn meta-data. This was
worked around in d3c9634e by setting core.autocrlf to "false" in the
per-repo config when initing the clone. However, if the config
variable was later changed, the corruption would still occur.

This patch tries to fix it while allowing core.autocrlf to be
enabled, by disabling filters when when hashing.

git-svn is currently the only call-site for hash_and_insert_object
(apart from the test-suite), so changing it should be safe.

836ff95df6 Git.pm: Use File::Temp->tempfile instead of ->new
Perl 5.8.0 ships with File::Temp 0.13, which does not have the new()
interface introduced in 0.14, as pointed out by Tom G. Christensen.

This modifies Git.pm to use the more established tempfile() interface
and updates 'git svn' to match.

e41352b24e Git.pm: Add faculties to allow temp files to be cached
This patch offers a generic interface to allow temp files to be
cached while using an instance of the 'Git' package. If many
temp files are created and destroyed during the execution of a
program, this caching mechanism can help reduce the amount of
files created and destroyed by the filesystem.

The temp_acquire method provides a weak guarantee that a temp
file will not be stolen by subsequent requests. If a file is
locked when another acquire request is made, a simple error is
thrown.

108c2aaf79 Git.pm: localise $? in command_close_bidi_pipe()
Git::DESTROY calls _close_cat_blob and _close_hash_and_insert_object,
which in turn call command_close_bidi_pipe, which calls waitpid, which
alters $?. If this happens during global destruction, it may alter the
program's exit status unexpectedly. Making $? local to the function
solves the problem.

(The problem was discovered due to a failure of test #8 in
t9106-git-svn-commit-diff-clobber.sh.)

31a92f6aa4 Git.pm: Add remote_refs() git-ls-remote frontend
This patch also converts the good ole' git-remote.perl to use it.
It is otherwise used in the repo.or.cz machinery and I guess other
scripts might find it useful too.

Unfortunately,

	git-ls-remote --heads .

is subtly different from

	git-ls-remote . refs/heads/

(since the second matches anywhere in the string, not just at the
beginning) so we have to provide interface for both.

32d8050a86 Git.pm: fix return value of config method
If config is called in array context, it is supposed to return all
values set for the given option key.  This works for all cases except
if there is no value set at all.  In that case, it wrongly returns
(undef) instead of ().  This fixes the return statement so that it
returns undef in scalar context but an empty array in array context.

d683a0e00c Git::cat_blob: allow using an empty blob to fix git-svn breakage
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.

b4c61ed6d3 Color support for "git-add -i"
This is mostly lifted from earlier series by Dan Zwell, but updated to
use "git config --get-color" and "git config --get-colorbool" to make it
simpler and more consistent with commands written in C.

A new configuration color.interactive variable is like color.diff and
color.status, and controls if "git-add -i" uses color.

A set of configuration variables, color.interactive.<slot>, are used to
define what color is used for the prompt, header, and help text.

For perl scripts, Git.pm provides $repo->get_color() method, which takes
the slot name and the default color, and returns the terminal escape
sequence to color the output text.  $repo->get_colorbool() method can be
used to check if color is set to be used for a given operation.

MakeMaker supports three installation modes: perl, site, and vendor. The first
and third install manpages to $PREFIX/share/man, only site installs to
$PREFIX/man. For consistency with the rest of git, which does not make the
distinction and writes all manpages to $PREFIX/share/man, this change makes
sure that perl does too, even when it's installed in site mode.
