pull: merge into unborn by fast-forwarding from empty tree
The logic for pulling into an unborn branch was originally
designed to be used on a newly-initialized repository
(d09e79c, git-pull: allow pulling into an empty repository,
2006-11-16). It thus did not initially deal with
uncommitted changes in the unborn branch. The case of an
_unstaged_ untracked file was fixed by 4b3ffe5 (pull: do not
clobber untracked files on initial pull, 2011-03-25).
However, it still clobbered existing staged files, both when
the file exists in the merged commit (it will be
overwritten), and when it does not (it will be deleted).
We fix this by doing a two-way merge, where the "current"
side of the merge is an empty tree, and the "target" side is
HEAD (already updated to FETCH_HEAD at this point). This
amounts to claiming that all work in the index was done vs.
an empty tree, and thus all content of the index is
precious.
Note that this use of read-tree just gives us protection
against overwriting index and working tree changes. It will
not actually result in a 3-way merge conflict in the index.
This is fine, as this is a rare situation, and the conflict
would not be interesting anyway (it must, by definition, be
an add/add conflict with the whole content conflicting). And
it makes it simpler for the user to recover, as they have no
HEAD to "git reset" back to.

When commit d09e79c taught git to pull into an unborn
branch, it first updated the unborn branch to point at the
pulled commit, and then used read-tree to update the index
and working tree. That ordering made sense, since any
failure of the latter step would be due to filesystem
errors, and one could then recover with "git reset --hard".
Later, commit 4b3ffe5 added extra safety for existing files
in the working tree by asking read-tree to bail out when it
would overwrite such a file. This error mode is much less
"your pull failed due to random errors" and more like "we
reject this pull because it would lose data". In that case,
it makes sense not to update the HEAD ref, just as a regular
rejected merge would do.
This patch reverses the order of the update-ref and
read-tree calls, so that we do not touch the HEAD ref at all if a
merge is rejected. This also means that we would not update
HEAD in case of a transient filesystem error, but those are
presumably less rare (and one can still recover by repeating
the pull, or by accessing FETCH_HEAD directly).
While we're reorganizing the code, we can drop the "exit 1"
from the end of our command chain. We exit immediately
either way, and just calling exit without an argument will
use the exit code from the last command.

http.c: don't rewrite the user:passwd string multiple times
Curl older than 7.17 (RHEL 4.X provides 7.12 and RHEL 5.X provides
7.15) requires that we manage any strings that we pass to it as
pointers. So, we really shouldn't be modifying this strbuf after we
have passed it to curl.
Our interaction with curl is currently safe (before or after this
patch) since the pointer that is passed to curl is never invalidated;
it is repeatedly rewritten with the same sequence of characters but
the strbuf functions never need to allocate a larger string, so the
same memory buffer is reused.
This "guarantee" of safety is somewhat subtle and could be overlooked
by someone who may want to add a more complex handling of the username
and password. So, let's stop modifying this strbuf after we have
passed it to curl, but also leave a note to describe the assumptions
that have been made about username/password lifetime and to draw
attention to the code.

Many "git submodule" operations do not work on a submodule at a path whose

This is because "git ls-files" is used to find which paths are bound to

for non ASCII pathnames.
Tell "git ls-files" to not C-quote its output, which is easier than unwrapping

read from $HOME owned by root" bug.
Merge branch 'jn/config-ignore-inaccessible' into maint
A git daemon that starts as "root" and then drops privilege often
leaves $HOME set to that of the root user, which is unreadable by
the daemon process, which was diagnosed as a configuration error.

the tightening which was originally meant as an additional security

discard_cache doesn't have to free the array of cache entries, because
the next call of read_cache can simply reuse it, as they all operate on
the global variable the_index.
discard_index on the other hand does have to free it, because it can be
used e.g. with index_state variables on the stack, in which case a
missing free would cause an unrecoverable leak. This patch releases the
memory and removes a comment that was relevant for discard_cache but has
become outdated.
Since discard_cache is just a wrapper around discard_index nowadays, we
lose the optimization that avoids reallocation of that array within
loops of read_cache and discard_cache. That doesn't cause a performance
regression for me, however (HEAD = this patch, HEAD^ = master + p0002):

gitweb: fix problem causing erroneous project list
The bug is manifest when running gitweb in a persistent process (e.g.
FastCGI, PSGI), and it's easy to reproduce. If a gitweb request
includes the searchtext parameter (i.e. s), subsequent requests using
the project_list action--which is the default action--and without
a searchtext parameter will be filtered by the searchtext value of the
first request. This is because the value of the $search_regexp global
(the value of which is based on the searchtext parameter) is currently
being persisted between requests.
Instead, clear $search_regexp before dispatching each request.

dir.c: fix ignore processing within not-ignored directories
As of 95c6f271 "dir.c: unify is_excluded and is_path_excluded APIs", the
is_excluded API no longer recurses into directories that match an ignore
pattern, and returns the directory's ignored state for all contained paths.
This is OK for normal ignore patterns, i.e. ignoring a directory affects
the entire contents recursively.
Unfortunately, this also "works" for negated ignore patterns ('!dir'), i.e.
the entire contents is "not-ignored" recursively, regardless of ignore
patterns that match the contents directly.
In prep_exclude, skip recursing into a directory only if it is really
ignored (i.e. the ignore pattern is not negated).

Case folding is not done correctly when matching against the [:upper:]
character class and uppercased character ranges (e.g. A-Z).
Specifically, an uppercase letter fails to match against any of them
when case folding is requested because plain characters in the pattern
and the whole string are preemptively lowercased to handle the base case
fast.
That optimization is kept and ISLOWER() is used in the [:upper:] case
when case folding is requested, while matching against a character range
is retried with toupper() if the character was lowercase, as the bounds
of the range itself cannot be modified (in a case-insensitive context,
[A-_] is not equivalent to [a-_]).

This patch was written with a different motivation. There is a problem
unique to push.default = current:
# on branch push-current-head
$ git push
# on another terminal
$ git checkout master
# return to the first terminal
# the push tried to push master!
This happens because the 'git checkout' on the second terminal races
with the 'git push' on the first terminal. Although this patch does not
solve the core problem (there is still no guarantee that 'git push' on
the first terminal will resolve HEAD before 'git checkout' changes HEAD
on the second), it works in practice.

Setting push.default to current adds the refspec "HEAD" for the
transport layer to handle. If "HEAD" doesn't resolve to a branch (and
since no refspec rhs is specified), the push fails after some time with
a cryptic error message:
$ git push
error: unable to push to unqualified destination: HEAD
The destination refspec neither matches an existing ref on the remote nor
begins with refs/, and we are unable to guess a prefix based on the source ref.
error: failed to push some refs to 'git@github.com:artagnon/git'
Fail early with a nicer error message:
$ git push
fatal: You are not currently on a branch.
To push the history leading to the current (detached HEAD)
state now, use
git push ram HEAD:<name-of-remote-branch>
