git-svn: do a partial rebuild if rev_map is out-of-date
Suppose you're using git-svn to work with a certain SVN repository.
Since you don't like 'git-svn fetch' to take forever, and you don't want
to accidentally interrupt it and end up corrupting your repository, you
set up a remote Git repository to mirror the SVN repository, which does
its own 'git-svn fetch' on a cronjob; now you can 'git-fetch' from the
Git mirror into your local repository, and still dcommit to SVN when you
have changes to push.
After you do this, though, git-svn will get very confused if you ever
try to do 'git-svn fetch' in your local repository again, since its
rev_map will differ from the branch's head, and it will be unable to
fetch new commits from SVN because of the metadata conflict. But all
the necessary metadata are there in the Git commit message; git-svn
already knows how to rebuild rev_map files that get blown away, by
using the metadata.
This patch teaches git-svn do a partial rebuild of the rev_map to
match the true state of the branch, if it ever is used to fetch again.
This will only work for projects not using either noMetadata or
useSvmProps configuration options; if you are using these options,
git-svn will fall back to the previous behaviour.

diff: fix "multiple regexp" semantics to find hunk header comment
When multiple regular expressions are concatenated with "\n", they were
traditionally AND'ed together, and only a line that matches _all_ of them
is taken as a match. This however is unwieldy when multiple regexp
feature is used to specify alternatives.
This fixes the semantics to take the first match. A nagative pattern, if
matches, makes the line to fail as before. A match with a positive
pattern will be the final match, and what it captures in $1 is used as the
hunk header comment.
We could write alternatives using "|" in ERE, but the machinery can only
use captured $1 as the hunk header comment (or $0 if there is no match in
$1), so you cannot write:
"junk ( A | B ) | garbage ( C | D )"
and expect both "junk" and "garbage" to get stripped with the existing
code. With this fix, you can write it as:
"junk ( A | B ) \n garbage ( C | D )"
and the way capture works would match the user expectation more
naturally.

diff.*.xfuncname which uses "extended" regex's for hunk header selection
Currently, the hunk headers produced by 'diff -p' are customizable by
setting the diff.*.funcname option in the config file. The 'funcname' option
takes a basic regular expression. This functionality was designed using the
GNU regex library which, by default, allows using backslashed versions of
some extended regular expression operators, even in Basic Regular Expression
mode. For example, the following characters, when backslashed, are
interpreted according to the extended regular expression rules: ?, +, and |.
As such, the builtin funcname patterns were created using some extended
regular expression operators.
Other platforms which adhere more strictly to the POSIX spec do not
interpret the backslashed extended RE operators in Basic Regular Expression
mode. This causes the pattern matching for the builtin funcname patterns to
fail on those platforms.
Introduce a new option 'xfuncname' which uses extended regular expressions,
and advertise it _instead_ of funcname. Since most users are on GNU
platforms, the majority of funcname patterns are created and tested there.
Advertising only xfuncname should help to avoid the creation of non-portable
patterns which work with GNU regex but not elsewhere.
Additionally, the extended regular expressions may be less ugly and
complicated compared to the basic RE since many common special operators do
not need to be backslashed.
For example, the GNU Basic RE:
^[ ]*\\(\\(public\\|static\\).*\\)$
becomes the following Extended RE:
^[ ]*((public|static).*)$

checkout: do not lose staged removal
The logic to checkout a different commit implements the safety to never
lose user's local changes. For example, switching from a commit to
another commit, when you have changed a path that is different between
them, need to merge your changes to the version from the switched-to
commit, which you may not necessarily be able to resolve easily. By
default, "git checkout" refused to switch branches, to give you a chance
to stash your local changes (or use "-m" to merge, accepting the risks of
getting conflicts).
This safety, however, had one deliberate hole since early June 2005. When
your local change was to remove a path (and optionally to stage that
removal), the command checked out the path from the switched-to commit
nevertheless.
This was to allow an initial checkout to happen smoothly (e.g. an initial
checkout is done by starting with an empty index and switching from the
commit at the HEAD to the same commit). We can tighten the rule slightly
to allow this special case to pass, without losing sight of removal
explicitly done by the user, by noticing if the index is truly empty when
the operation begins.

push: receiver end advertises refs from alternate repositories
Earlier, when pushing into a repository that borrows from alternate object
stores, we followed the longstanding design decision not to trust refs in
the alternate repository that houses the object store we are borrowing
from. If your public repository is borrowing from Linus's public
repository, you pushed into it long time ago, and now when you try to push
your updated history that is in sync with more recent history from Linus,
you will end up sending not just your own development, but also the
changes you acquired through Linus's tree, even though the objects needed
for the latter already exists at the receiving end. This is because the
receiving end does not advertise that the objects only reachable from the
borrowed repository (i.e. Linus's) are already available there.
This solves the issue by making the receiving end advertise refs from
borrowed repositories. They are not sent with their true names but with a
phoney name ".have" to make sure that the old senders will safely ignore
them (otherwise, the old senders will misbehave, trying to push matching
refs, and mirror push that deletes refs that only exist at the receiving
end).
Junio C Hamano [Tue, 9 Sep 2008 08:27:09 +0000 (01:27 -0700)]
push: prepare sender to receive extended ref information from the receiver
"git push" enhancement allows the receiving end to report not only its own
refs but refs in repositories it borrows from via the alternate object
store mechanism. By telling the sender that objects reachable from these
extra refs are already complete in the receiving end, the number of
objects that need to be transfered can be cut down.
These entries are sent over the wire with string ".have", instead of the
actual names of the refs. This string was chosen so that they are ignored
by older programs at the sending end. If we sent some random but valid
looking refnames for these entries, "matching refs" rule (triggered when
running "git push" without explicit refspecs, where the sender learns what
refs the receiver has, and updates only the ones with the names of the
refs the sender also has) and "delete missing" rule (triggered when "git
push --mirror" is used, where the sender tells the receiver to delete the
refs it itself does not have) would try to update/delete them, which is
not what we want.
This prepares the send-pack (and "push" that runs native protocol) to
accept extended existing ref information and make use of it. The ".have"
entries are excluded from ref matching rules, and are exempt from deletion
rule while pushing with --mirror option, but are still used for pack
generation purposes by providing more "bottom" range commits.
