might create an rr-cache directory. Add a note that simply invoking

In prepare_attr_stack, we pop the old elements of the stack
(which were left from a previous lookup and may or may not
be useful to us). Our loop to do so checks that we never
reach the top of the stack. However, the code immediately
afterwards will segfault if we did actually reach the top of
the stack.
Fortunately, this is not an actual bug, since we will never
pop all of the stack elements (we will always keep the root
gitattributes, as well as the builtin ones). So the extra
check in the loop condition simply clutters the code and
makes the intent less clear. Let's get rid of it.

When we prepare the attribute stack for a lookup on a path,
we start with the cached stack from the previous lookup
(because it is common to do several lookups in the same
directory hierarchy). So the first thing we must do in
preparing the stack is to pop any entries that point to
directories we are no longer interested in.
For example, if our stack contains gitattributes for:
foo/bar/baz
foo/bar
foo
but we want to do a lookup in "foo/bar/bleep", then we want
to pop the top element, but retain the others.
To do this we walk down the stack from the top, popping
elements that do not match our lookup directory. However,
the test do this simply checked strncmp, meaning we would
mistake "foo/bar/baz" as a leading directory of
"foo/bar/baz_plus". We must also check that the character
after our match is '/', meaning we matched the whole path
component.
There are two special cases to consider:
1. The top of our attr stack has the empty path. So we
must not check for '/', but rather special-case the
empty path, which always matches.
2. Typically when matching paths in this way, you would
also need to check for a full string match (i.e., the
character after is '\0'). We don't need to do so in
this case, though, because our path string is actually
just the directory component of the path to a file
(i.e., we know that it terminates with "/", because the
filename comes after that).

Originally, this code remained relatively silent when we
failed to connect to the cache. The idea was that it was
simply a cache, and we didn't want to bother the user with
temporary failures (the worst case is that we would simply
ask their password again).
However, if you have a configuration failure or other
problem, it is helpful for the daemon to report those
problems. Git will happily ignore the failed error code, but
the extra information to stderr can help the user diagnose
the problem.

On many systems, the sockaddr_un.sun_path field is quite
small. Even on Linux, it is only 108 characters. A user of
the credential-cache daemon can easily surpass this,
especially if their home directory is in a deep directory
tree (since the default location expands ~/.git-credentials).
We can hack around this in the unix-socket.[ch] code by
doing a chdir() to the enclosing directory, feeding the
relative basename to the socket functions, and then
restoring the working directory.
This introduces several new possible error cases for
creating a socket, including an irrecoverable one in the
case that we can't restore the working directory. In the
case of the credential-cache code, we could perhaps get away
with simply chdir()-ing to the socket directory and never
coming back. However, I'd rather do it at the lower level
for a few reasons:
1. It keeps the hackery behind an opaque interface instead
of polluting the main program logic.
2. A hack in credential-cache won't help any unix-socket
users who come along later.
3. The chdir trickery isn't that likely to fail (basically
it's only a problem if your cwd is missing or goes away
while you're running). And because we only enable the
hack when we get a too-long name, it can only fail in
cases that would have failed under the previous code
anyway.

In test 'blame --textconv with local changes' of t8006-blame-textconv,
using /usr/xpg4/bin/sed (as set by SANE_TOOL_PATH), an additional
newline was added to the output from the 'helper' script.
This was noted by sed with a message such as:
sed: Missing newline at end of file zero.bin.
Sed then exits with status 2 causing the helper script to also exit
with status 2.
In turn, this was triggering a fatal error from git blame:
fatal: unable to read files to diff
To work around this difference in sed behaviour, use perl -p instead
of sed -e as it exits cleanly and does not insert the additional
newline.

The sendemail.multiedit variable is meant to be a boolean.
However, it is not marked as such in the code, which means
we store its value literally. Thus in the do_edit function,
perl ends up coercing it to a boolean value according to
perl rules, not git rules. This works for "0", but "false",
"no", or "off" will erroneously be interpreted as true.

The wording seems to suggest that creating the directory is needed and the
setting of rerere.enabled is only for disabling the feature by setting it
to 'false'. But the configuration is meant to be the primary control and
setting it to 'true' will enable it; the rr-cache directory will be
created as necessary and the user does not have to create it.

The old code basically did:
generate array of SHA1s for alternate refs
for each unique SHA1 in array:
add_extra_ref(".have", sha1)
for each ref (including real refs and extra refs):
show_ref(refname, sha1)
But there is no need to stuff the alternate refs in extra_refs; we can
call show_ref() directly when iterating over the array, then handle
real refs separately. So change the code to:
generate array of SHA1s for alternate refs
for each unique SHA1 in array:
show_ref(".have", sha1)
for each ref (this now only includes real refs):
show_ref(refname, sha1)

Run "git grep" in "grep" search with '-z' option, to be able to parse
response also for files with filename containing ':' character. The
':' character is otherwise (without '-z') used to separate filename
from line number and from matched line.
Note that this does not protect files with filename containing
embedded newline. This would be hard but doable for text files, and
harder or even currently impossible with binary files: git does not
quote filename in
"Binary file <foo> matches"
message, but new `--break` and/or `--header` options to git-grep could

There were two bugs in generating file links (links to "blob" view),
one hidden by the other. The correct way of generating file link is
href(action=>"blob", hash_base=>$co{'id'},
file_name=>$file);
It was $co{'hash'} (this key does not exist, and therefore this is
undef), and 'hash' instead of 'hash_base'.
To have this fix applied in single place, this commit also reduces
code duplication by saving file link (which is used for line links) in
$file_href.

While identifying the commit merged to our history as "parent #2" is
technically correct, we will never say "parent #1" (as that is the tip of
our history before the merge is made), and we rarely would say "parent #3"
(which would mean the merge is an octopus), especially when responding to
a request to pull a signed tag.

say "merged tag '<tagname>'" instead.

The current code is removing the trailing "/", but computing the string
length on the previous value, i.e. with the trailing "/". Later in the
code, we do
my $path = substr($File::Find::name, $pfxlen + 1);
And the "$pfxlen + 1" is supposed to mean "the length of the prefix, plus
1 for the / separating the prefix and the path", but with an incorrect
$pfxlen, this basically eats the first character of the path, and yields
"404 - No projects found".
While we're there, also fix $pfxdepth to use $dir, although a change of 1
in the depth shouldn't really matter.

The FETCH_HEAD refname is supposed to refer to the ref that was fetched
and should be merged. However all fetched refs are written to
.git/FETCH_HEAD in an arbitrary order, and resolve_ref_unsafe simply
takes the first ref as the FETCH_HEAD, which is often the wrong one,
when other branches were also fetched.
The solution is to write the for-merge ref(s) to FETCH_HEAD first.
Then, unless --append is used, the FETCH_HEAD refname behaves as intended.
If the user uses --append, they presumably are doing so in order to
preserve the old FETCH_HEAD.
While we are at it, update an old example in the read-tree documentation
that implied that each entry in FETCH_HEAD only has the object name, which
is not true for quite a while.
