receive-pack: close sideband fd on early pack errors
Since commit a22e6f8 (receive-pack: send pack-processing
stderr over sideband, 2012-09-21), receive-pack will start
an async sideband thread to copy the stderr from our
index-pack or unpack-objects child to the client. We hand
the thread's input descriptor to unpack(), which puts it in
the "err" member of the "struct child_process".
After unpack() returns, we use finish_async() to reap the
sideband thread. The thread is only ready to die when it
gets EOF on its pipe, which is connected to the err
descriptor. So we expect all of the write ends of that pipe
to be closed as part of unpack().
Normally, this works fine. After start_command forks, it
closes the parent copy of the descriptor. Then once the
child exits (whether it was successful or not), that closes
the only remaining writer.
However, there is one code-path in unpack() that does not
handle this. Before we decide which of unpack-objects or
index-pack to use, we read the pack header ourselves to see
how many objects it contains. If there is an error here, we
exit without running either sub-command, the pipe descriptor
remains open, and we are in a deadlock, waiting for the
sideband thread to die (which is in turn waiting for us to
close the pipe).
We can fix this by making sure that unpack() always closes
the pipe before returning.

git add: rework the logic to warn "git add <pathspec>..." default change
The earlier logic to warn against "git add subdir" that is run
without "-A" or "--no-all" was only to check any <pathspec> given
exactly spells a directory name that (still) exists on the
filesystem. This had number of problems:
* "git add '*dir'" (note that the wildcard is hidden from the
shell) would not trigger the warning.
* "git add '*.py'" would behave differently between the current
version of Git and Git 2.0 for the same reason as "subdir", but
would not trigger the warning.
* "git add dir" for a submodule "dir" would just update the index
entry for the submodule "dir" without ever recursing into it, and
use of "-A" or "--no-all" would matter. But the logic only
checks the directory-ness of "dir" and gives an unnecessary
warning.
Rework the logic to detect the case where the behaviour will be
different in Git 2.0, and issue a warning only when it matters.
Even with the code before this warning, "git add subdir" will have
to traverse the directory in order to find _new_ files the index
does not know about _anyway_, so we can do this check without adding
an extra pass to find if <pathspec> matches any removed file.
This essentially updates the "add_files_to_cache()" public API to
"update_files_in_cache()" API that is internal to "git add", because
with the "--all" option, the function is no longer about "adding"
paths to the cache, but is also used to remove them.
There are other callers of the former from "checkout" (used when
"checkout -m" prepares the temporary tree that represents the local
modifications to be merged) and "commit" ("commit --include" that
picks up local changes in addition to what is in the index). Since
ADD_CACHE_IGNORE_ERRORS (aka "--no-all") is not used by either of
them, once dust settles after Git 2.0 and the warning becomes
unnecessary, we may want to unify these two functions again.

When "cat-file -p" prints commits, it shows them in their
raw format, since git's format is already human-readable.
For tags, however, we print the whole thing raw except for
one thing: we convert the timestamp on the tagger line into a
human-readable date.
This dates all the way back to a0f15fa (Pretty-print tagger
dates, 2006-03-01). At that time there was no other way to
pretty-print a tag. These days, however, neither of those
matters much. The normal way to pretty-print a tag is with
"git show", which is much more flexible than "cat-file -p".
Commit a0f15fa also built "verify-tag --verbose" (and
subsequently "tag -v") around the "cat-file -p" output.
However, that behavior was lost in commit 62e09ce (Make git
tag a builtin, 2007-07-20), and we went back to printing
the raw tag contents. Nobody seems to have noticed the bug
since then (and it is arguably a saner behavior anyway, as
it shows the actual bytes for which we verified the
signature).
Let's drop the tagger-date formatting for "cat-file -p". It
makes us more consistent with cat-file's commit
pretty-printer, and as a bonus, we can drop the hand-rolled
tag parsing code in cat-file (which happened to behave
inconsistently with the tag pretty-printing code elsewhere).
This is a change of output format, so it's possible that
some callers could considered this a regression. However,
the original behavior was arguably a bug (due to the
inconsistency with commits), likely nobody was relying on it
(even we do not use it ourselves these days), and anyone
relying on the "-p" pretty-printer should be able to expect
a change in the output format (i.e., while "cat-file" is
plumbing, the output format of "-p" was never guaranteed to
be stable).

run-command: use thread-aware die_is_recursing routine
If we die from an async thread, we do not actually exit the
program, but just kill the thread. This confuses the static
counter in usage.c's default die_is_recursing function; it
updates the counter once for the thread death, and then when
the main program calls die() itself, it erroneously thinks
we are recursing. The end result is that we print "recursion
detected in die handler" instead of the real error in such a
case (the easiest way to trigger this is having a remote
connection hang up while running a sideband demultiplexer).
This patch solves it by using a per-thread counter when the
async_die function is installed; we detect recursion in each
thread (including the main one), but they do not step on
each other's toes.
Other threaded code does not need to worry about this, as
they do not install specialized die handlers; they just let
a die() from a sub-thread take down the whole program.
Since we are overriding the default recursion-check
function, there is an interesting corner case that is not a
problem, but bears some explanation. Imagine the main thread
calls die(), and then in the die_routine starts an async
call. We will switch to using thread-local storage, which
starts at 0, for the main thread's counter, even though
the original counter was actually at 1. That's OK, though,
for two reasons:
1. It would miss only the first level of recursion, and
would still find recursive failures inside the async
helper.
2. We do not currently and are not likely to start doing
anything as heavyweight as starting an async routine
from within a die routine or helper function.
Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
When any git code calls die or die_errno, we use a counter
to detect recursion into the die functions from any of the
helper functions. However, such a simple counter is not good
enough for threaded programs, which may call die from a
sub-thread, killing only the sub-thread (but incrementing
the counter for everyone).
Rather than try to deal with threads ourselves here, let's
just allow callers to plug in their own recursion-detection
function. This is similar to how we handle the die routine
(the caller plugs in a die routine which may kill only the
sub-thread).

http: set curl FAILONERROR each time we select a handle
Because we reuse curl handles for multiple requests, the
setup of a handle happens in two stages: stable, global
setup and per-request setup. The lifecycle of a handle is
something like:
1. get_curl_handle; do basic global setup that will last
through the whole program (e.g., setting the user
agent, ssl options, etc)
2. get_active_slot; set up a per-request baseline (e.g.,
clearing the read/write functions, making it a GET
request, etc)
3. perform the request with curl_*_perform functions
4. goto step 2 to perform another request
Breaking it down this way means we can avoid doing global
setup from step (1) repeatedly, but we still finish step (2)
with a predictable baseline setup that callers can rely on.
Until commit 6d052d7 (http: add HTTP_KEEP_ERROR option,
2013-04-05), setting curl's FAILONERROR option was a global
setup; we never changed it. However, 6d052d7 introduced an
option where some requests might turn off FAILONERROR. Later
requests using the same handle would have the option
unexpectedly turned off, which meant they would not notice
http failures at all.
This could easily be seen in the test-suite for the
"half-auth" cases of t5541 and t5551. The initial requests
turned off FAILONERROR, which meant it was erroneously off
for the rpc POST. That worked fine for a successful request,
but meant that we failed to react properly to the HTTP 401
(instead, we treated whatever the server handed us as a
successful message body).
The solution is simple: now that FAILONERROR is a
per-request setting, we move it to get_active_slot to make
sure it is reset for each request.
