Jeff King 7253a02348 http-backend: fix die recursion with custom handler When we die() in http-backend, we call a custom handler that writes an HTTP 500 response to stdout, then reports the error to stderr. Our routines for writing out the HTTP response may themselves die, leading to us entering die() again. When it was originally written, that was OK; our custom handler keeps a variable to notice this and does not recurse. However, since `cd163d4` (usage.c: detect recursion in die routines and bail out immediately, 2012-11-14), the main die() implementation detects recursion before we even get to our custom handler, and bails without printing anything useful. We can handle this case by doing two things: 1. Installing a custom die_is_recursing handler that allows us to enter up to one level of recursion. Only the first call to our custom handler will try to write out the error response. So if we die again, that is OK. If we end up dying more than that, it is a sign that we are in an infinite recursion. 2. Reporting the error to stderr before trying to write out the HTTP response. In the current code, if we do die() trying to write out the response, we'll exit immediately from this second die(), and never get a chance to output the original error (which is almost certainly the more interesting one; the second die is just going to be along the lines of "I tried to write to stdout but it was closed").

	Git - the stupid content tracker

////////////////////////////////////////////////////////////////

"git" can mean anything, depending on your mood.

 - random three-letter combination that is pronounceable, and not
   actually used by any common UNIX command.  The fact that it is a
   mispronunciation of "get" may or may not be relevant.
 - stupid. contemptible and despicable. simple. Take your pick from the
   dictionary of slang.
 - "global information tracker": you're in a good mood, and it actually
   works for you. Angels sing, and a light suddenly fills the room.
 - "goddamn idiotic truckload of sh*t": when it breaks

Git is a fast, scalable, distributed revision control system with an
unusually rich command set that provides both high-level operations
and full access to internals.

Git is an Open Source project covered by the GNU General Public
License version 2 (some parts of it are under different licenses,
compatible with the GPLv2). It was originally written by Linus
Torvalds with help of a group of hackers around the net.

Please read the file INSTALL for installation instructions.

See Documentation/gittutorial.txt to get started, then see
Documentation/giteveryday.txt for a useful minimum set of commands, and
Documentation/git-commandname.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with "man gittutorial" or "git help tutorial", and the
documentation of each command with "man git-commandname" or "git help
commandname".

CVS users may also want to read Documentation/gitcvs-migration.txt
("man gitcvs-migration" or "git help cvs-migration" if git is
installed).

Many Git online resources are accessible from http://git-scm.com/
including full documentation and Git related tools.

The user discussion and development of Git take place on the Git
mailing list -- everyone is welcome to post bug reports, feature
requests, comments and patches to git@vger.kernel.org (read
Documentation/SubmittingPatches for instructions on patch submission).
To subscribe to the list, send an email with just "subscribe git" in
the body to majordomo@vger.kernel.org. The mailing list archives are
available at http://news.gmane.org/gmane.comp.version-control.git/,
http://marc.info/?l=git and other archival sites.

The maintainer frequently sends the "What's cooking" reports that
list the current status of various development topics to the mailing
list.  The discussion following them give a good reference for
project status, development direction and remaining tasks.
