t5570: fix forwarding of git-daemon messages via cat
The shell function that starts git-daemon wants to read the first line of
the daemon's stderr to ensure that it started correctly. Subsequent daemon
errors should be redirected to fd 4 (which is the terminal in verbose mode
or /dev/null in quiet mode). To that end the shell script used 'read' to
get the first line of output, and then 'cat &' to forward everything else
in a background process.
The problem is, that 'cat >&4 &' does not produce any output because the
shell redirects a background process's stdin to /dev/null. To have this
command invocation do anything useful, we have to redirect its stdin
explicitly (which overrides the /dev/null redirection).
The shell function connects the daemon's stderr to its consumers via a
FIFO. We cannot just do this:
read line <git_daemon_output
cat <git_daemon_output >&4 &
because after the first redirection the pipe is closed and the daemon
could receive SIGPIPE if it writes at the wrong moment. Therefore, we open
the readable end of the FIFO only once on fd 7 in the shell and dup from
there to the stdin of the two consumers.

git-remote-testgit: fix race when spawning fast-import
Test "pushing to local repo" in t5800-remote-helpers can hang
due to a race condition in git-remote-testgit. Fix it by
setting stdin to unbuffered.
On the writer side, "git push" invokes push_refs_with_export(),
which sends to stdout the command "export\n" and immediately
starts up "git fast-export". The latter writes its output stream
to the same stdout.
On the reader side, remote helper "git-remote-testgit" reads from
stdin to get its next command. It uses getc() to read characters
from libc up until \n. Libc has buffered a potentially much
larger chunk of stdin. When it sees the "export\n" command, it
forks "git fast-import" to read the stream.
If fast-export finishes before git fast-import starts, the
fast-export output can end up in libc's buffer in
git-remote-testgit, rather than in git fast-import. The latter
hangs indefinitely on a now-empty stdin.

descendants of current HEAD (or are HEAD). We've hit this while updating
master to origin/master but accidentaly we called (while being on master):
$ git merge master origin/master
Here is a minimal testcase:
$ git init a && cd a
$ echo a >a && git add a
$ git commit -minitial
$ echo b >a && git add a
$ git commit -msecond
$ git checkout master^
$ git merge master master
Fast-forwarding to: master
Already up-to-date with master
Merge made by the 'octopus' strategy.

properly keep track of current working directory
Various failure modes in the repository detection code path currently
quote the wrong directory in their error message. The working directory
is changed iteratively to the parent directory until a git repository is
found. If the working directory cannot be changed to the parent
directory for some reason, the detection gives up and prints an error
message. The error message should report the current working directory.
Instead of continually updating the 'cwd' variable, which is actually
used to remember the original working directory, the 'offset' variable
is used to keep track of the current working directory. At the point
where the affected error handling code is called, 'offset' already
points to the end of the parent of the working directory, rather than
the current working directory.
Fix this by explicitly using a variable 'offset_parent' and update
'offset' concurrently with the call to chdir.
In a similar fashion, the function get_device_or_die() would print the
original working directory in case of a failure, rather than the current
working directory. Fix this as well by making use of the 'offset'
variable.
Lastly, replace the phrase 'mount parent' with 'mount point'. The former
appears to be a typo.

submodules: recursive fetch also checks new tags for submodule commits
Since
88a21979c (fetch/pull: recurse into submodules when necessary) all
fetched commits are examined if they contain submodule changes (unless
configuration or command line options inhibit that). If a newly recorded
submodule commit is not present in the submodule, a fetch is run inside
it to download that commit.
Checking new refs was done in an else branch where it wasn't executed for
tags. This normally isn't a problem because tags are only fetched with
the branches they live on, then checking the new commits in the fetched
branches for submodule commits will also process all tags. But when a
specific tag is fetched (or the refspec contains refs/tags/) commits only
reachable by tags won't be searched for submodule commits, which is a bug.
Fix that by moving the code outside the if/else construct to handle new
tags just like any other ref. The performance impact of adding tags that
most of the time lie on a branch which is checked anyway for new submodule
commit should be minimal, as since
6859de4 (fetch: avoid quadratic loop
checking for updated submodules) all ref-tips are collected first and then
fed to a single rev-list.

http: use newer curl options for setting credentials
We give the username and password to curl by sticking them

mechanism, where you can specify each element individually.
This has the advantage that a username can contain a ":"

http: clean up leak in init_curl_http_auth
When we have a credential to give to curl, we must copy it
into a "user:pass" buffer and then hand the buffer to curl.
Old versions of curl did not copy the buffer, and we were
expected to keep it valid. Newer versions of curl will copy
the buffer.
Our solution was to use a strbuf and detach it, giving
ownership of the resulting buffer to curl. However, this
meant that we were leaking the buffer on newer versions of
curl, since curl was just copying it and throwing away the
string we passed. Furthermore, when we replaced a
credential (e.g., because our original one was rejected), we
were also leaking on both old and new versions of curl.
This got even worse in the last patch, which started
replacing the credential (and thus leaking) on every http
request.
Instead, let's use a static buffer to make the ownership
more clear and less leaky. We already keep a static "struct
credential", so we are only handling a single credential at
a time, anyway.

remote-curl: main test case for the OS command line overflow
This is main test case for the original problem that triggered this
patch series. We create a repo with 50k tags and then test whether
git-clone over the smart HTTP protocol succeeds.
Note that we construct the repo in a slightly different way than the
original script used to reproduce the problem. This is because the
original script just created 50k tags all pointing to the same commit,
so if there was a bug where remote-curl.c was not passing all the refs
to fetch-pack we wouldn't know. The clone would succeed even if only one
tag was passed, because all the other tags were pointing at the same SHA
and would be considered present.
Instead we create a repo with 50k independent (dangling) commits and
then tag each of those commits with a unique tag. This way if one of the
tags is not given to fetch-pack, later stages of the clone would
complain about it.
This allows us to test both that the command line overflow was fixed, as
well as that it was fixed in a way that doesn't leave out any of the
refs.

fast-import: tighten parsing of datarefs
The syntax for the use of mark references in fast-import
demands either a SP (space) or LF (end-of-line) after
a mark reference. Fast-import does not complain when garbage
appears after a mark reference in some cases.
Factor out parsing of mark references and complain if
errant characters are found. Also be a little more careful
when parsing "inline" and SHA1s, complaining if extra
characters appear or if the form of the dataref is unrecognized.
Buggy input can cause fast-import to produce the wrong output,
silently, without error. This makes it difficult to track
down buggy generators of fast-import streams. An example is
seen in the last line of this commit command:
commit refs/heads/S2
committer Name <name@example.com>
1112912893 -0400
data <<COMMIT
commit message
COMMIT
from :1M 100644 :103 hello.c
It is missing a newline and should be:
[...]
from :1
M 100644 :103 hello.c
What fast-import does is to produce a commit with the same
contents for hello.c as in refs/heads/S2^. What the buggy
program was expecting was the contents of blob :103. While
the resulting commit graph looked correct, the contents in
some commits were wrong.

run-command: treat inaccessible directories as ENOENT
When execvp reports EACCES, it can be one of two things:
1. We found a file to execute, but did not have

2. We did not have permissions to look in some directory
in the $PATH.
In the former case, we want to consider this a
permissions problem and report it to the user as such (since
getting this for something like "git foo" is likely a
configuration error).
In the latter case, there is a good chance that the
inaccessible directory does not contain anything of
interest. Reporting "permission denied" is confusing to the
user (and prevents our usual "did you mean...?" lookup). It
also prevents git from trying alias lookup, since we do so
only when an external command does not exist (not when it
exists but has an error).
This patch detects EACCES from execvp, checks whether we are
in case (2), and if so converts errno to ENOENT. This
behavior matches that of "bash" (but not of simpler shells
that use execvp more directly, like "dash").

superfluous combined diff output in between other hunks) or
not (in which case you get the combined diff and the program

The current behavior was not planned, and is just what the

remove unmerged entries from our list of modified files, and
print a warning that we are ignoring them.
We can cheaply find which entries are unmerged by adding

There is one non-obvious thing we must change when parsing
this combined output. Before this patch, when we saw a
numstat line for a file that did not have index changes, we
would create a new record with 'unchanged' in the 'INDEX'
field. Because "--raw" comes before "--numstat", we must
move this special-case down to the raw-line case (and it is
sufficient to move it rather than handle it in both places,

fetch-pack: new --stdin option to read refs from stdin
If a remote repo has too many tags (or branches), cloning it over the
smart HTTP transport can fail because remote-curl.c puts all the refs
from the remote repo on the fetch-pack command line. This can make the
command line longer than the global OS command line limit, causing
fetch-pack to fail.
This is especially a problem on Windows where the command line limit is
orders of magnitude shorter than Linux. There are already real repos out
there that msysGit cannot clone over smart HTTP due to this problem.
Here is an easy way to trigger this problem:
git init too-many-refs
cd too-many-refs
echo bla > bla.txt
git add .
git commit -m test
sha=$(git rev-parse HEAD)
tag=$(perl -e 'print "bla" x 30')
for i in `seq 50000`; do
echo $sha refs/tags/$tag-$i >> .git/packed-refs
done
Then share this repo over the smart HTTP protocol and try cloning it:
$ git clone http://localhost/.../too-many-refs/.git
Cloning into 'too-many-refs'...
fatal: cannot exec 'fetch-pack': Argument list too long
50k tags is obviously an absurd number, but it is required to
demonstrate the problem on Linux because it has a much more generous
command line limit. On Windows the clone fails with as little as 500
tags in the above loop, which is getting uncomfortably close to the
number of tags you might see in real long lived repos.
This is not just theoretical, msysGit is already failing to clone our
company repo due to this. It's a large repo converted from CVS, nearly
10 years of history.
Four possible solutions were discussed on the Git mailing list (in no
particular order):
1) Call fetch-pack multiple times with smaller batches of refs.
This was dismissed as inefficient and inelegant.
2) Add option --refs-fd=$n to pass a an fd from where to read the refs.
This was rejected because inheriting descriptors other than
stdin/stdout/stderr through exec() is apparently problematic on Windows,
plus it would require changes to the run-command API to open extra
pipes.
3) Add option --refs-from=$tmpfile to pass the refs using a temp file.
This was not favored because of the temp file requirement.
4) Add option --stdin to pass the refs on stdin, one per line.
In the end this option was chosen as the most efficient and most
desirable from scripting perspective.
There was however a small complication when using stdin to pass refs to
fetch-pack. The --stateless-rpc option to fetch-pack also uses stdin for
communication with the remote server.
If we are going to sneak refs on stdin line by line, it would have to be
done very carefully in the presence of --stateless-rpc, because when
reading refs line by line we might read ahead too much data into our
buffer and eat some of the remote protocol data which is also coming on
stdin.
One way to solve this would be to refactor get_remote_heads() in
fetch-pack.c to accept a residual buffer from our stdin line parsing
above, but this function is used in several places so other callers
would be burdened by this residual buffer interface even when most of
them don't need it.
In the end we settled on the following solution:
If --stdin is specified without --stateless-rpc, fetch-pack would read
the refs from stdin one per line, in a script friendly format.
However if --stdin is specified together with --stateless-rpc,
fetch-pack would read the refs from stdin in packetized format
(pkt-line) with a flush packet terminating the list of refs. This way we
can read the exact number of bytes that we need from stdin, and then
get_remote_heads() can continue reading from the same fd without losing
a single byte of remote protocol data.
This way the --stdin option only loses generality and scriptability when
used together with --stateless-rpc, which is not easily scriptable
anyway because it also uses pkt-line when talking to the remote server.
