The parent git process is supposed to send us an empty line to indicate that the conversation is over. However, the parent process may die() if there is a problem with the operation (e.g., we try to fetch a ref that does not exist). In this case, it produces a useful message, but then remote-curl _also_ produces an unhelpful message: $ git pull origin matser fatal: couldn't find remote ref matser Unexpected end of command stream The "right" way to fix this is to teach the parent git to always cleanly close the connection to the helper, letting it know that we are done. Implementing that is rather clunky, though, as it would involve either replacing die() operations with returning errors up the stack (until we disconnect the transport), or adding an atexit handler to clean up any transport helpers left open. It's much simpler to just suppress the EOF message in remote-curl. It was not added to address any real-world situation in the first place, but rather a "we should probably report unexpected things" suggestion[1]. It is the parent git which drives the operation, and whose exit value actually matters. If the parent dies, then the helper has no need to complain (except as a debugging aid). In the off chance that the pipe is closed without the parent dying, it can still notice the non-zero exit code.

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/everyday.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.
