Currently, if you want to use gettext or eval_gettext to format a message
you may have to add a separate echo statement and a surrounding subshell
in order to interpolate the required trailing new line.
This patch introduces two new helper functions, gettextln and eval_gettextln
which append a trailing newline to the gettext output.
This allows constructions of the form:
if test -s "$GIT_DIR/BISECT_START"
then
(
gettext "You need to give me at least one good and one bad revisions.
(You can use \"git bisect bad\" and \"git bisect good\" for that.)" &&
echo
) >&2
else
...
to be expressed more concisely as:
if test -s "$GIT_DIR/BISECT_START"
then
gettextln "You need to give me at least one good and one bad revisions.
(You can use \"git bisect bad\" and \"git bisect good\" for that.)" >&2
else
...

Add a $(uname_S) case for Minix with the correct options.
Minix's linker needs all libraries specified explicitly.
Add NEEDS_SSL_WITH_CURL to add -lssl when using -lcurl.
Add NEEDS_IDN_WITH_CURL to add -lidn when using -lcurl.
When NEEDS_SSL_WITH_CURL is defined and NEEDS_CRYPTO_WITH_SSL
is defined, add -lcrypt to CURL_LIBCURL.
Change OPENSSL_LINK to OPENSSL_LIBSSL in the
NEEDS_CRYPTO_WITH_SSL conditional in the libopenssl
section. Libraries go in OPENSSL_LIBSSL, OPENSSL_LINK
is for linker flags.

This optimizes the "recency order" (see pack-heuristics.txt in
Documentation/technical/ directory) used to order objects within a
packfile in three ways:
- Commits at the tip of tags are written together, in the hope that
revision traversal done in incremental fetch (which starts by
putting them in a revision queue marked as UNINTERESTING) will see a
better locality of these objects;
- In the original recency order, trees and blobs are intermixed. Write
trees together before blobs, in the hope that this will improve
locality when running pathspec-limited revision traversal, i.e.
"git log paths...";
- When writing blob objects out, write the whole family of blobs that use
the same delta base object together, by starting from the root of the
delta chain, and writing its immediate children in a width-first
manner, in the hope that this will again improve locality when reading
blobs that belong to the same path, which are likely to be deltified
against each other.
I tried various workloads in the Linux kernel repositories (HEAD at
v3.0-rc6-71-g4dd1b49) packed with v1.7.6 and with this patch, counting how
large seeks are needed between adjacent accesses to objects in the pack,
and the result looks promising. The history has 2072052 objects, weighing
some 490MiB.
* Simple commit-only log.
$ git log >/dev/null
There are 254656 commits in total.

Less than 2MiB seek: 61.71% 62.87%
With the current pack heuristics, more than 30% of accesses have to
seek further than 300MB; the updated pack heuristics ensures that less
than 0.1% of accesses have to seek further than 135MB. This is largely
due to the fact that the updated heuristics does not mix blobs and
trees together.

The result is very similar to the pathspec-limited log above, which
only looks at the tree objects.
* Packing recent history.
$ (git for-each-ref --format='^%(refname)' refs/tags; echo HEAD) |
git pack-objects --revs --stdout >/dev/null
This should pack data worth 71 commits.

Less than 2MiB seek: 77.09% 99.04%
The long-tail part of the result looks worse with the patch, but
the change helps majority of the access. 99.04% of the accesses
need less than 2MiB of seeking, compared to 77.09% with the current
packing heuristics.
* Index pack.
$ git index-pack -v .git/objects/pack/pack*.pack

Less than 2MiB seek: 81.73% 96.92%
As the index-pack command already walks objects in the delta chain
order, writing the blobs out in the delta chain order seems to
drastically improve the locality of access.
Note that a half-a-gigabyte packfile comfortably fits in the buffer cache,
and you would unlikely to see much performance difference on a modern and
reasonably beefy machine with enough memory and local disks. Benchmarking
with cold cache (or over NFS) would be interesting.

In a workload other than "git log" (without pathspec nor any option that
causes us to inspect trees and blobs), the recency pack order is said to
cause the access jump around quite a bit. Add a hook to allow us observe
how bad it is.
"git config core.logpackaccess /var/tmp/pal.txt" will give you the log
in the specified file.

Many examples of git command invocation are given in asciidoc listing
blocks, which makes them monospaced and avoids further interpretation of
special characters. Some manpages make a list of examples, like:
git foo::
Run git foo.
git foo -q::
Use the "-q" option.
to quickly show many variants. However, they can sometimes be hard to
read, because they are shown in a proportional-width font (so, for
example, seeing the difference between "-- foo" and "--foo" can be
difficult).
This patch puts all such examples into backticks, which gives the
equivalent formatting to a listing block (i.e., monospaced and without
character interpretation).
As a bonus, this also fixes an example in the git-push manpage, in which
"git push origin :::" was accidentally considered a newly-indented list,
and not a list item with "git push origin :" in it.

This makes it easy to customize the git diff-tree options, for example
to include -p to include inline diffs.
It defaults to the current options "--stat --summary --find-copies-harder"
and thus is backward-compatible.

In most cases, fetching the remote HEAD explicitly is
unnecessary. It's just a symref pointing to a branch which
we are already fetching, so we will already ask for its sha1.
However, if the remote has a detached HEAD, things are less
certain. We do not ask for HEAD's sha1, but we do try to
write it into a local detached HEAD. In most cases this is
fine, as the remote HEAD is pointing to some part of the
history graph that we will fetch via the refs.
But if the remote HEAD points to an "orphan" commit (one
which was is not an ancestor of any refs), then we will not
have the object, and update_ref will complain when we try to
write the detached HEAD, aborting the whole clone.
This patch makes clone always explicitly ask the remote for
the sha1 of its HEAD commit. In the non-detached case, this
is a no-op, as we were going to ask for that sha1 anyway. In
the regular detached case, this will add an extra "want" to
the protocol negotiation, but will not change the history
that gets sent. And in the detached orphan case, we will
fetch the orphaned history so that we can write it into our
local detached HEAD.

The guess_remote_head function tries to figure out where a
remote's HEAD is pointing by comparing the sha1 of the
remote's HEAD with the sha1 of various refs found on the
remote. However, we were too liberal in matching refs, and
would match tags or remote tracking branches, even though
these things could not possibly be referenced by the HEAD
symbolic ref (since git will detach when checking them out).
As a result, a clone of a remote repository with a detached
HEAD might write "refs/tags/*" into our local HEAD, which is
bogus. The resulting HEAD should be detached.
The other related code path is remote.c's get_head_names()
(which is used for, among other things, "set-head -a"). This was
not affected, however, as that function feeds only refs from
refs/heads to guess_remote_head.

We didn't test this setup at all, and doing so reveals a few
bugs:
1. Cloning a repository with an orphaned detached HEAD
(i.e., one that points to history that is not
referenced by any ref) will fail.
2. Cloning a repository with a detached HEAD that points
to a tag will cause us to write a bogus "refs/tags/..."
ref into the HEAD symbolic ref. We should probably
detach instead.
3. Cloning a repository with a detached HEAD that points
to a branch will cause us to checkout that branch. This
is a known limitation of the git protocol (we have to
guess at HEAD's destination, since the symref contents
aren't shown to us). This test serves to document the
desired behavior, which can only be achieved once the
git protocol learns to share symref information.

Kirill Smelkov noticed that post-1.7.6 "git checkout"
started leaking tons of memory. The streaming_write_entry
function properly calls close_istream(), but that function
did not actually free() the allocated git_istream struct.
The git_istream struct is totally opaque to calling code,
and must be heap-allocated by open_istream. Therefore it's
not appropriate for callers to have to free it.
This patch makes close_istream() into "close and de-allocate
all associated resources". We could add a new "free_istream"
call, but there's not much point in letting callers inspect
the istream after close. And this patch's semantics make us
match fopen/fclose, which is well-known and understood.

Previously the refspec capability could not be listed as
required or their parsing would break.
Most likely the reason the second hunk wasn't caught is because the
series that added 'refspec' as capability, and the one that added
required capabilities were done in parallel.

Currently the helper must somehow guess how many import statements to
read before it starts outputting its fast-export stream. This is
because the remote helper infrastructure runs fast-import only once,
so the helper is forced to output one stream for all import commands
it will receive. The only reason this worked in the past was because
only one ref was imported at a time.
Change the semantics of the import statement such that it matches
that of the push statement. That is, the import statement is followed
by a series of import statements that are terminated by a '\n'.

In other words, use fast-export --use-done-feature to add a 'done'
command at the end of streams passed to remote helpers' "import"
commands, and teach the remote helpers implementing "export" to use
the 'done' command in turn when producing their streams.
The trailing \n in the protocol signals the helper that the
connection is about to close, allowing it to do whatever cleanup
neccesary.
Previously, the connection would already be closed by the
time the trailing \n was to be written. Now that the remote-helper
protocol uses the new done command in its fast-import streams, this
is no longer the case and we can safely write the trailing \n.

If fast-export is being used to generate a fast-import stream that
will be used afterwards it is desirable to indicate the end of the
stream with the new 'done' command.

Add a 'done' command that causes fast-import to stop reading from the
stream and exit.
If the new --done command line flag was passed on the command line
(or a "feature done" declaration included at the start of the stream),
make the 'done' command mandatory. So "git fast-import --done"'s
input format will be prefix-free, making errors easier to detect when
they show up as early termination at some convenient time of the
upstream of a pipe writing to fast-import.
Another possible application of the 'done' command would to be allow a
fast-import stream that is only a small part of a larger encapsulating
stream to be easily parsed, leaving the file offset after the "done\n"
so the other application can pick up from there. This patch does not
teach fast-import to do that --- fast-import still uses buffered input
(stdio).

Trying to push for local repositories will fail since there is no
local checkout in .git/info/... to push from as that is only used for
non-local repositories (local repositories are pushed to directly).
This went unnoticed because the transport helper infrastructure does
not check the return value of the helper.

The gitdir capability is recognized by git and can be used to tell
the helper where the .git directory is. But it is not mentioned in
the documentation and considered worse than if gitdir was passed
via GIT_DIR environment variable.
Remove support for the gitdir capability and export GIT_DIR instead.
Teach testgit to use env instead of the now-removed gitdir command.

When a remote helper exports to a non-local git repo, the
steps are roughly:
1. fast-export into a local staging area; the set of
interesting refs is defined by what is in the fast-export
stream
2. git push from the staging area to the non-local repo
In the second step, we should explicitly push all refs, not
just matching ones. This will let us push refs that do not
yet exist in the remote repo.

When we want to push to a remote helper that has the
"export" capability, we collect all of the refs we want to
push and then feed them to fast-export.
However, the list of refs is actually a list of remote refs,
not local refs. The mapped local refs are included via the
peer_ref pointer. So when we add an argument to our
fast-export command line, we must be sure to use the local
peer_ref name (and if there is no local name, it is because
we are not actually sending that ref, or we may not even
have the ref at all).

Upon receiving an "import" command, the testgit remote
helper would ignore the ref asked for by git and generate a
fast-export stream based on HEAD. Instead, we should
actually give git the ref it asked for.
This requires adding a new parameter to the export_repo
method in the remote-helpers python library, which may be
used by code outside of git.git. We use a default parameter
so that callers without the new parameter will get the same
behavior as before.

These are all things one might expect to work in a helper
that is capable of handling multiple branches (which our
testgit helper in theory should be able to do, as it is
backed by git). All of these bugs are specific to the
import/export codepaths, so they don't affect helpers like
git-remote-curl that use fetch/push commands.
The first and fourth tests are about fetching and pushing
new refs, and demonstrate bugs in the git_remote_helpers
library (so they would be most likely to impact helpers for
other VCSs which import/export git).
The second test is about importing multiple refs; it
demonstrates a bug in git-remote-testgit, which is mostly
for exercising the test code. Therefore it probably doesn't
affect anyone in practice.
The third test demonstrates a bug in git's side of the
helper code when the upstream has added refs that we do not
have locally. This could impact git users who use remote
helpers to access foreign VCSs.
All of those bugs have fixes later in this series.
The fifth test is the most complex, and does not have a fix
in this series. It tests pushing a ref via the export
mechanism to a new name on the remote side (i.e.,
"git push $remote old:new").
The problem is that we push all of the work of generating
the export stream onto fast-export, but we have no way of
communicating to fast-export that this name mapping is
happening. So we tell fast-export to generate a stream with
the commits for "old", but we can't tell it to label them
all as "new".
