bdcaebbedd Merge branch 'mm/send-email-cc-cruft-after-address'
"git send-email" attempts to pick up valid e-mails from the
trailers, but people in real world write non-addresses there, like
"Cc: Stable <add@re.ss> # 4.8+", which broke the output depending
on the availability and vintage of Mail::Address perl module.

dcfafc5214 Git.pm: add comment pointing to t9000
parse_mailboxes should probably eventually be completely equivalent to
Mail::Address, and if this happens we can drop the Mail::Address
dependency. Add a comment in the code reminding the current state of the
code, and point to the corresponding failing test to help future
contributors to get it right.

e3fdbcc8e1 parse_mailboxes: accept extra text after <...> address
The test introduced in this commit succeeds without the patch to Git.pm
if Mail::Address is installed, but fails otherwise because our in-house
parser does not accept any text after the email address. They succeed
both with and without Mail::Address after this commit.

Mail::Address accepts extra text and considers it as part of the name,
iff the address is surrounded with <...>. The implementation mimics
this behavior as closely as possible.

This mostly restores the behavior we had before b1c8a11 (send-email:
allow multiple emails using --cc, --to and --bcc, 2015-06-30), but we
keep the possibility to handle comma-separated lists.

112423eb90 git-svn: "git worktree" awareness
git-svn internals were previously not aware of repository
layout differences for users of the "git worktree" command.
Introduce this awareness by using "git rev-parse --git-path"
instead of relying on outdated uses of GIT_DIR and friends.

b26098fc2f git-svn: reduce scope of input record separator change
Reducing the scope of where we change the record separator ($/)
avoids bugs in calls which rely on the input record separator
further down, such as the 'chomp' usage in command_oneline.

This is necessary for a future change to git-svn, but exists in
Git.pm since it seems useful for gitweb and our other Perl
scripts, too.

0b6641557c git-svn: fix auth parameter handling on SVN 1.9.0+
For users with "store-passwords = no" set in the "[auth]" section of
their ~/.subversion/config, SVN 1.9.0+ would fail with the
following message when attempting to call svn_auth_set_parameter:

  Value is not a string (or undef) at Git/SVN/Ra.pm

Ironically, this breakage was caused by r1553823 in subversion:

  "Make svn_auth_set_parameter() usable from Perl bindings."

Since 2007 (602015e0e6), git-svn has used a workaround to make
svn_auth_set_parameter usable internally.  However this workaround
breaks under SVN 1.9+, which deals properly with the type mapping
and fails to recognize our workaround.

For pre-1.9.0 SVN, we continue to use the existing workaround for
the lack of proper type mapping in the bindings.

Tested under subversion 1.6.17 and 1.9.3.

I've also verified r1553823 was not backported to SVN 1.8.x:

  BRANCH=http://svn.apache.org/repos/asf/subversion/branches/1.8.x
  svn log -v $BRANCH/subversion/bindings/swig/core.i

888ab716ad Git.pm: stop assuming that absolute paths start with a slash
On Windows, absolute paths never start with a slash, unless a POSIX
emulation layer is used. The latter is the case for MSYS2's Perl that
Git for Windows leverages. However, in the tests we also go through
plain `git.exe`, which does *not* leverage the POSIX emulation layer,
and therefore the paths we pass to Perl may actually be DOS-style paths
such as C:/Program Files/Git.

So let's just use Perl's own way to test whether a given path is
absolute or not instead of home-brewing our own.

This patch partially fixes t7800 and t9700 when running in Git for
Windows' SDK.

8262574822 git-svn: improve rebase/mkdirs performance
Processing empty_dir directives becomes extremely slow for svn
repositories with a large enough history.

This is due to using a single hash to store the list of empty
directories, with the expensive step being purging items from
that hash using grep+delete.

Storing directories in a hash of hashes improves the performance
of this purge step and removes a potentially lengthy delay after
every rebase/mkdirs command.

The svn repository with this behaviour has 110K commits with
unhandled.log containing 170K empty_dir directives.

This takes 10 minutes to process when using a single hash, vs
3 seconds with a hash of hashes.

8d314d7afe send-email: reduce dependencies impact on parse_address_line
parse_address_line had not the same behavior whether the user had
Mail::Address or not. Teach parse_address_line to behave like
Mail::Address.

When the user input is correct, this implementation behaves
exactly like Mail::Address except when there are quotes
inside the name:

  "Jane Do"e <jdoe@example.com>

In this case the result of parse_address_line is:

  With M::A : "Jane Do" e <jdoe@example.com>
  Without   : "Jane Do e" <jdoe@example.com>

When the user input is not correct, the behavior is also mostly
the same.

Unlike Mail::Address, this doesn't parse groups and recursive
commentaries.

  Git::SVN::*: avoid premature FileHandle closure

Kyle J. McKay
e426311bef Git::SVN::*: avoid premature FileHandle closure
Since b19138b (git-svn: Make it incrementally faster by minimizing temp
files, v1.6.0), git-svn has been using the Git.pm temp_acquire and
temp_release mechanism to avoid unnecessary temp file churn and provide
a speed boost.

However, that change introduced a call to temp_acquire inside the
Git::SVN::Fetcher::close_file function for an 'svn_hash' temp file.
Because an SVN::Pool is active at the time this function is called, if
the Git::temp_acquire function ends up actually creating a new
FileHandle for the temp file (which it will the first time it's called
with the name 'svn_hash') that FileHandle will end up in the SVN::Pool
and should that pool have SVN::Pool::clear called on it that FileHandle
will be closed out from under Git::temp_acquire.

Since the only call site to Git::temp_acquire with the name 'svn_hash'
is inside the close_file function, if an 'svn_hash' temp file is ever
created its FileHandle is guaranteed to be created in the active
SVN::Pool.

This has not been a problem in the past because the SVN::Pool was not
being cleared.  However, since dfa72fdb (git-svn: reload RA every
log-window-size, v2.2.0) the pool has been getting cleared periodically
at which point the FileHandle for the 'svn_hash' temp file gets closed.
Any subsequent calls to Git::temp_acquire for 'svn_hash', however,
succeed without creating/opening a new temporary file since it still has
the now invalid FileHandle in its cache.  Callers that then attempt to
use that FileHandle fail with an error.

We avoid this problem by making sure the 'svn_hash' temp file is created
in the same place the 'svn_delta_...' and 'git_blob_...' temp files are
(and then temp_release'd) so that it can be safely used inside the
close_file function without having its FileHandle end up in an SVN::Pool
that gets cleared.

Additionally the Git.pm cat_blob function creates a bidirectional pipe
FileHandle using the IPC::Open2::open2 function.  If that handle is
created too late, it also gets caught up in the SVN::Pool and incorrectly
closed by the SVN::Pool::clear call.  But this only seems to happen with
more recent versions of Perl and svn.

To avoid this problem we add an explicit call to _open_cat_blob_if_needed
before the first call to SVN::Pool->new_default to make sure the open2
handle does not end up in the SVN::Pool.

We can delay loading some modules until we need them for uncommon
code paths.  For example, persistent memoization is not often
needed, so we can avoid loading the modules for it until we
encounter svn::mergeinfo during fetch.

This gives a tiny reduction in syscalls (from 15641 to 15305) when
running "git svn info" and counting via "strace -fc".  Further,
more invasive work will be needed to noticeably improve performance.

83c9433e67 git-svn: support for git-svn propset
This change allows git-svn to support setting subversion properties.

It is useful for manually setting properties when committing to a
subversion repo that *requires* properties to be set without requiring
moving your changeset to separate subversion checkout in order to
set props.

This change is initially from David Fraser, appearing at:

  http://mid.gmane.org/1927112650.1281253084529659.JavaMail.root@klofta.sjsoft.com>

They are now forward-ported to most recent git along with fixes to
deal with files in subdirectories.

Style and functional changes from Eric Wong have been taken
in their entirety from:

  http://mid.gmane.org/20141201094911.GA13931@dcvr.yhbt.net

There is a nit to point out: the code does not support
adding props unless there are also content changes to the files as
well.  This is demonstrated in the testcase.

process never uses more than 60MB RSS on my x86-64 GNU/Linux system[2].
This 60M measurement is only for the git-svn Perl process itself and
does not include memory used by git subprocesses accessing large packs
(subprocess memory usage _is_ measured by my time(1) tool).

Before this change, an import took longer (2:20) on svn+ssh:// but
git-svn used around 240MB during the imports.  Worse yet, git-svn
ballooned to over 400M when writing out the cache to the filesystem.

I also tried removing memoization for `has_no_changes', too, but a
local copy of the R repository(*) was not close to finishing within
10 hours on my system.

dfa72fdb96 git-svn: reload RA every log-window-size
Despite attempting to use local memory pools everywhere we can,
(including our call to SVN::Ra::do_update and all subsequent reporter
calls), there does not appear to be a way to force the Git::SVN::Fetcher
callbacks to use a pool other than the per-SVN::Ra pool.
Git::SVN::Fetcher ends up using the main RA pool which grows
monotonically in size for the lifetime of the RA object.

Thus the only way to free that memory appears to be to destroy and
recreate the RA connection for at every --log-window-size interval.

This reduces memory usage over the course of fetching 10K revisions
using a test repository created with the script at the end of this
commit message.

As reported by time(1) on my x86-64 system:

	before: 54024k
	 after: 28680k

Unfortunately, there remains some yet-to-be-tracked-down slow memory
growth which would be evident as the `nr' parameter increases in
the repository generation script:
-----------------------------8<------------------------------
set -e
tmp=$(mktemp -d svntestrepo-XXXXXXXX)
svnadmin create "$tmp"
repo=file://"$(cd $tmp && pwd)"
svn co "$repo" "$tmp/wd"
cd "$tmp/wd"
if ! test -f a
then
	> a
	svn add a
	svn commit -m 'A'
fi

nr=10000
while test $nr -gt 0
do
	echo $nr > a
	svn commit -q -m A
	nr=$((nr - 1))
done
echo "repository created in $repo"

abfef3bbf5 git-svn: only look at the new parts of svn:mergeinfo
In a Subversion repository where many feature branches are merged into a
trunk, the svn:mergeinfo property can grow very large. This severely
slows down git-svn's make_log_entry() because it is checking all
mergeinfo entries every time the property changes.

In most cases, the additions to svn:mergeinfo since the last commit are
pretty small, and there is nothing to gain by checking merges that were
already checked for the last commit in the branch.

Add a mergeinfo_changes() function which computes the set of interesting
changes to svn:mergeinfo since the last commit. Filter out merged
branches whose ranges haven't changed, and remove a common prefix of
ranges from other merged branches.

This speeds up "git svn fetch" by several orders of magnitude on a large
repository where thousands of feature branches have been merged.

561d952ed4 Merge branch 'mm/pager-less-sans-S'
Since the very beginning of Git, we gave the LESS environment a
default value "FRSX" when we spawn "less" as the pager.  "S" (chop
long lines instead of wrapping) has been removed from this default
set of options, because it is more or less a personal taste thing,
as opposed to others that have good justifications (i.e. "R" is very
much justified because many kinds of output we produce are colored
and "FX" is justified because output we produce is often shorter
than a page).

Existing users who prefer not to see line-wrapped output may want to
set

  $ git config core.pager "less -S"

to restore the traditional behaviour.  It is expected that people
find output from the most subcommands easier to read with the new
default, except for "blame" which tends to produce really long
lines.  To override the new default only for "git blame", you can do
this:

  $ git config pager.blame "less -S"

b3275838d9 pager: remove 'S' from $LESS by default
By default, Git used to set $LESS to -FRSX if $LESS was not set by
the user. The FRX flags actually make sense for Git (F and X because
sometimes the output Git pipes to less is short, and R because Git
pipes colored output). The S flag (chop long lines), on the other
hand, is not related to Git and is a matter of user preference. Git
should not decide for the user to change LESS's default.

More specifically, the S flag harms users who review untrusted code
within a pager, since a patch looking like:

    -old code;
    +new good code; [... lots of tabs ...] malicious code;

would appear identical to:

    -old code;
    +new good code;

Users who prefer the old behavior can still set the $LESS environment
variable to -FRSX explicitly, or set core.pager to 'less -S'.

The documentation in config.txt is made a bit longer to keep both an
example setting the 'S' flag (needed to recover the old behavior)
and an example showing how to unset a flag set by Git.

e54c1f2d25 pager: set LV=-c alongside LESS=FRSX
On systems with lv configured as the preferred pager (i.e.,
DEFAULT_PAGER=lv at build time, or PAGER=lv exported in the
environment) git commands that use color show control codes instead of
color in the pager:

	$ git diff
	^[[1mdiff --git a/.mailfilter b/.mailfilter^[[m
	^[[1mindex aa4f0b2..17e113e 100644^[[m
	^[[1m--- a/.mailfilter^[[m
	^[[1m+++ b/.mailfilter^[[m
	^[[36m@@ -1,11 +1,58 @@^[[m

"less" avoids this problem because git uses the LESS environment
variable to pass the -R option ('output ANSI color escapes in raw
form') by default.  Use the LV environment variable to pass 'lv' the
-c option ('allow ANSI escape sequences for text decoration / color')
to fix it for lv, too.

Noticed when the default value for color.ui flipped to 'auto' in
v1.8.4-rc0~36^2~1 (2013-06-10).

2394e94e83 git-svn: workaround for a bug in svn serf backend
Subversion serf backend in versions 1.8.5 and below has a bug(*) that the
function creating the descriptor of a file change -- add_file() --
doesn't make a copy of its third argument when storing it on the
returned descriptor.  As a result, by the time this field is used (in
transactions of file copying or renaming) it may well be released, and
the memory reused.

One of its possible manifestations is the svn assertion triggering on an
invalid path, with a message

svn_fspath__skip_ancestor: Assertion
`svn_fspath__is_canonical(child_fspath)' failed.

This patch works around this bug, by storing the value to be passed as
the third argument to add_file() in a local variable with the same scope
as the file change descriptor, making sure their lifetime is the same.

73ffac3b38 git-svn: fix termination issues for remote svn connections
git-svn used in combination with serf to talk to svn repository
served over HTTPS dumps core on termination.

This is caused by a bug in serf, and the most recent serf release
1.3.1 still exhibits the problem; a fix for the bug exists (see
https://code.google.com/p/serf/source/detail?r=2146).

Until the bug is fixed, work around the issue within the git perl
module Ra.pm by freeing the private copy of the remote access object
on termination, which seems to be sufficient to prevent the error
from happening.

Note: Since subversion-1.8.0 and later do require serf-1.2.1 or
later, this issue typically shows up when upgrading to a recent
version of subversion.

Credits go to Jonathan Lambrechts for proposing a fix to Ra.pm,
Evgeny Kotkov and Ivan Zhakov for fixing the issue in serf and
pointing me to that fix.

When the temp_is_locked function was introduced, there was
a desire to make _temp_cache use it.  Unfortunately due to the
various tests and logic flow involved changing the _temp_cache
function to use the new temp_is_locked function is problematic
as _temp_cache needs a slightly different test than is provided
by the temp_is_locked function.

This change reverts use of temp_is_locked in the _temp_cache
function and restores the original code that existed there
before the temp_is_locked function was added.

8ac251b66b git-svn: allow git-svn fetching to work using serf
When attempting to git-svn fetch files from an svn https?: url using
the serf library (the only choice starting with svn 1.8) the following
errors can occur:

Temp file with moniker 'svn_delta' already in use at Git.pm line 1250
Temp file with moniker 'git_blob' already in use at Git.pm line 1250

David Rothenberger <daveroth@acm.org> has determined the cause to
be that ra_serf does not drive the delta editor in a depth-first
manner [...]. Instead, the calls come in this order:

1. open_root
2. open_directory
3. add_file
4. apply_textdelta
5. add_file
6. apply_textdelta

When using the ra_serf access method, git-svn can end up needing
to create several temp files before the first one is closed.

This change causes a new temp file moniker to be generated if the
one that would otherwise have been used is currently locked.

The actual complaint appears to be a bug in the underlying
implementation.  What's interesting here is that it is apparently
_triggered_ by closing stderr, which results in (from strace)

  write(2, "fatal: Needed a single revision\n", 32) = -1 EBADF (Bad file descriptor)
  write(2, "\0", 1) = -1 EBADF (Bad file descriptor)

Closing stderr is a bad idea anyway: there is a very real chance that
we print fatal error messages to some other file that just happens to
be opened on the now-free FD 2.  So let's not do that.

As pointed out by Eric Wong (thanks), the initial close needs to go:
die() would again write nowhere if we close STDERR beforehand.

See http://www.open.collab.net/community/subversion/articles/merge-info.html
Extract:
The range r30430:30435 that was added to 1.5.x in this merge has a '*' suffix for 1.5.x\www.
This '*' is the marker for a non-inheritable mergeinfo range.
The '*' means that only the path on which the mergeinfo is explicitly set has had this range merged into it.

712c6adaee Git.pm: fix cat_blob crashes on large files
Read and write each 1024 byte buffer, rather than trying to buffer
the entire content of the file.  We are only copying the contents to
a file descriptor and do not use it ourselves.

Previous code would crash on all files > 2 Gib, when the offset
variable became negative (perhaps below the level of perl),
resulting in a crash.  On a 32 bit system, or a system with low
memory it might crash before reaching 2 GiB due to memory
exhaustion.

This code may leave a partial file behind in case of failure, where
the old code would leave a completely empty file.  Neither version
verifies the correctness of the content.  Calling code must take
care of verification and cleanup.

75f7b5dfc4 perl/Git.pm: fix get_tz_offset to properly handle DST boundary cases
When passed a local time that was on the boundary of a DST change,
get_tz_offset returned a GMT offset that was incorrect (off by one
hour).  This is because the time was converted to GMT and then back to
a time stamp via timelocal() which cannot disambiguate boundary cases
as noted in its documentation.

Modify this algorithm, using an approach suggested in

  http://article.gmane.org/gmane.comp.version-control.git/213871

to first convert the timestamp in question to two broken down forms
with localtime() and gmtime(), and then compute what timestamps
these two broken down forms would represent in GMT (i.e. a timezone
that does not have DST issues) by applying timegm() on them.  The
difference between the resulting timestamps is the timezone offset.

This avoids the ambigious conversion and allows a correct time to be
returned on every occassion.

cc3046271d git-svn: do not escape certain characters in paths
Subversion 1.7 and newer implement HTTPv2, an extension that should make HTTP
more efficient. Servers with support for this protocol will make the subversion
client library take an alternative code path that checks (with assertions)
whether the URL is "canonical" or not.

This patch fixes an issue I encountered while trying to `git svn dcommit` a
rename action for a file containing a single quote character ("User's Manual"
to "UserMan.tex"). It does not happen for older subversion 1.6 servers nor
non-HTTP(S) protocols such as the native svn protocol, only on an Apache server
shipping SVN 1.7. Trying to `git svn dcommit` under the aforementioned
conditions yields the following error which aborts the commit process:

    Committing to http://example.com/svn ...
    perl: subversion/libsvn_subr/dirent_uri.c:1520: uri_skip_ancestor:
Assertion `svn_uri_is_canonical(child_uri, ((void *)0))' failed.
    error: git-svn died of signal 6

An analysis of the subversion source for the cause:

- The assertion originates from uri_skip_ancestor which calls
  svn_uri_is_canonical, which fails when the URL contains percent-encoded values
  that do not necessarily have to be encoded (not "canonical" enough). This is
  done by a table lookup in libsvn_subr/path.c. Putting some debugging prints
  revealed that the character ' is indeed encoded to %27 which is not
  considered canonical.
- url_skip_ancestor is called by svn_ra_neon__get_baseline_info with the root
  repository URL and path as parameters;
- which is called by copy_resource (libsvn_ra_neon/commit.c) for a copy action
  (or in my case, renaming which is actually copy + delete old);
- which is called by commit_add_dir;
- which is assigned as a structure method "add_file" in
  svn_ra_neon__get_commit_editor.

In the whole path, the path argument is not modified.

Through some more uninteresting wrapper functions, the Perl bindings gives you
access to the add_file method which will pass the path argument without
modifications to svn.

git-svn calls the "R"(ename) subroutine in Git::SVN::Editor which contains:
326         my $fbat = $self->add_file($self->repo_path($m->{file_b}), $pbat,
327                                 $self->url_path($m->{file_a}), $self->{r});
"repo_path" basically returns the path as-is, unless the "svn.pathnameencoding"
configuration property is set. "url_path" tries to escape some special
characters, but does not take all special characters into account, thereby
causing the path to contain some escaped characters which do not have to be
escaped.

The list of characters not to be escaped are taken from the
subversion/libsvn_subr/path.c file to fully account for all characters. Tested
with a filename containing all characters in the range 0x20 to 0x78 (inclusive).

9012f571b4 git svn: do not overescape URLs (fallback case)
Subversion's canonical URLs are intended to make URL comparison easy
and therefore have strict rules about what characters are special
enough to urlencode and what characters should be left alone.

When in the fallback codepath because unable to use libsvn's own
canonicalization function for some reason, escape special characters
in URIs according to the svn_uri__char_validity[] table in
subversion/libsvn_subr/path.c (r935829).  The libsvn versions that
trigger this code path are not likely to be strict enough to care, but
it's nicer to be consistent.

Noticed by using SVN 1.6.17 perl bindings, which do not provide
SVN::_Core::svn_uri_canonicalize (triggering the fallback code),
with libsvn 1.7.5, whose do_switch is fussy enough to care:

  Committing to file:///home/jrn/src/git/t/trash%20directory.\

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 \

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.

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.
