The config option color.grep.match can be used to specify the highlighting
color for matching strings. Add the options matchContext and matchSelected
to allow different colors to be specified for matching strings in the
context vs. in selected lines. This is similar to the ms and mc specifiers
in GNU grep's environment variable GREP_COLORS.

This memoization appears unneeded as the check_cherry_pick2 cache is
in front of it does enough.
With this change applied, importing from local svn+ssh and http copies
of the R repo[1] takes only 2:00 (2 hours) on my system and the git-svn
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.

This override was probably never necessary, but most likely a no-op
as it does not appear to do anything in SVN::Ra itself.
Signed-off-by: Eric Wong <normalperson@yhbt.net>
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"

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.
