chain kill signals for cleanup functions
If a piece of code wanted to do some cleanup before exiting
(e.g., cleaning up a lockfile or a tempfile), our usual
strategy was to install a signal handler that did something
like this:
do_cleanup(); /* actual work */
signal(signo, SIG_DFL); /* restore previous behavior */
raise(signo); /* deliver signal, killing ourselves */
For a single handler, this works fine. However, if we want
to clean up two _different_ things, we run into a problem.
The most recently installed handler will run, but when it
removes itself as a handler, it doesn't put back the first
handler.
This patch introduces sigchain, a tiny library for handling
a stack of signal handlers. You sigchain_push each handler,
and use sigchain_pop to restore whoever was before you in
the stack.

quickfetch(): Prevent overflow of the rev-list command line
quickfetch() calls rev-list to check whether the objects we are about to
fetch are already present in the repo (if so, we can skip the object fetch).
However, when there are many (~1000) refs to be fetched, the rev-list
command line grows larger than the maximum command line size on some systems
(32K in Windows). This causes rev-list to fail, making quickfetch() return
non-zero, which unnecessarily triggers the transport machinery. This somehow
causes fetch to fail with an exit code.
By using the --stdin option to rev-list (and feeding the object list to its
standard input), we prevent the overflow of the rev-list command line,
which causes quickfetch(), and subsequently the overall fetch, to succeed.
However, using rev-list --stdin is not entirely straightforward: rev-list
terminates immediately when encountering an unknown object, which can
trigger SIGPIPE if we are still writing object's to its standard input.
We therefore temporarily ignore SIGPIPE so that the fetch process is not
terminated.
The patch also contains a testcase to verify the fix (note that before
the patch, the testcase would only fail on msysGit).

quickfetch(): Prevent overflow of the rev-list command line
quickfetch() calls rev-list to check whether the objects we are about to
fetch are already present in the repo (if so, we can skip the object fetch).
However, when there are many (~1000) refs to be fetched, the rev-list
command line grows larger than the maximum command line size on some systems
(32K in Windows). This causes rev-list to fail, making quickfetch() return
non-zero, which unnecessarily triggers the transport machinery. This somehow
causes fetch to fail with an exit code.
By using the --stdin option to rev-list (and feeding the object list to its
standard input), we prevent the overflow of the rev-list command line,
which causes quickfetch(), and subsequently the overall fetch, to succeed.
However, using rev-list --stdin is not entirely straightforward: rev-list
terminates immediately when encountering an unknown object, which can
trigger SIGPIPE if we are still writing object's to its standard input.
We therefore temporarily ignore SIGPIPE so that the fetch process is not
terminated.
The patch also contains a testcase to verify the fix (note that before
the patch, the testcase would only fail on msysGit).

use write_str_in_full helper to avoid literal string lengths
In 2d14d65 (Use a clearer style to issue commands to remote helpers,
2009-09-03) I happened to notice two changes like this:
- write_in_full(helper->in, "list\n", 5);
+
+ strbuf_addstr(&buf, "list\n");
+ write_in_full(helper->in, buf.buf, buf.len);
+ strbuf_reset(&buf);
IMHO, it would be better to define a new function,
static inline ssize_t write_str_in_full(int fd, const char *str)
{
return write_in_full(fd, str, strlen(str));
}
and then use it like this:
- strbuf_addstr(&buf, "list\n");
- write_in_full(helper->in, buf.buf, buf.len);
- strbuf_reset(&buf);
+ write_str_in_full(helper->in, "list\n");
Thus not requiring the added allocation, and still avoiding
the maintenance risk of literal string lengths.
These days, compilers are good enough that strlen("literal")
imposes no run-time cost.
Transformed via this:
perl -pi -e \
's/write_in_full\((.*?), (".*?"), \d+\)/write_str_in_full($1, $2)/'\
$(git grep -l 'write_in_full.*"')

Give error when no remote is configured
When there's no explicitly-named remote, we use the remote specified
for the current branch, which in turn defaults to "origin". But it
this case should require the remote to actually be configured, and not
fall back to the path "origin".
Possibly, the config file's "remote = something" should require the
something to be a configured remote instead of a bare repository URL,
but we actually test with a bare repository URL.
In fetch, we were giving the sensible error message when coming up
with a URL failed, but this wasn't actually reachable, so move that
error up and use it when appropriate.
In push, we need a new error message, because the old one (formerly
unreachable without a lot of help) used the repo name, which was NULL.

remote.c: Fix overtight refspec validation
We tightened the refspec validation code in an earlier commit ef00d15
(Tighten refspec processing, 2008-03-17) per my suggestion, but the
suggestion was misguided to begin with and it broke this usage:
$ git push origin HEAD~12:master
The syntax of push refspecs and fetch refspecs are similar in that they
are both colon separated LHS and RHS (possibly prefixed with a + to
force), but the similarity ends there. For example, LHS in a push refspec
can be anything that evaluates to a valid object name at runtime (except
when colon and RHS is missing, or it is a glob), while it must be a
valid-looking refname in a fetch refspec. To validate them correctly, the
caller needs to be able to say which kind of refspecs they are. It is
unreasonable to keep a single interface that cannot tell which kind it is
dealing with, and ask it to behave sensibly.
This commit separates the parsing of the two into different functions, and
clarifies the code to implement the parsing proper (i.e. splitting into
two parts, making sure both sides are wildcard or neither side is).
This happens to also allow pushing a commit named with the esoteric "look
for that string" syntax:
$ git push ../test.git ':/remote.c: Fix overtight refspec:master'
