2012-01-08dashed externals: kill children on exitLibravatar Clemens Buchacher3-1/+3
Several git commands are so-called dashed externals, that is commands executed as a child process of the git wrapper command. If the git wrapper is killed by a signal, the child process will continue to run. This is different from internal commands, which always die with the git wrapper command. Enable the recently introduced cleanup mechanism for child processes in order to make dashed externals act more in line with internal commands.

2012-01-08run-command: optionally kill children on exitLibravatar Jeff King2-0/+69
When we spawn a helper process, it should generally be done and finish_command called before we exit. However, if we exit abnormally due to an early return or a signal, the helper may continue to run in our absence. In the best case, this may simply be wasted CPU cycles or a few stray messages on a terminal. But it could also mean a process that the user thought was aborted continues to run to completion (e.g., a push's pack-objects helper will complete the push, even though you killed the push process). This patch provides infrastructure for run-command to keep track of PIDs to be killed, and clean them on signal reception or input, just as we do with tempfiles. PIDs can be added in two ways: 1. If NO_PTHREADS is defined, async helper processes are automatically marked. By definition this code must be ready to die when the parent dies, since it may be implemented as a thread of the parent process. 2. If the run-command caller specifies the "clean_on_exit" option. This is not the default, as there are cases where it is OK for the child to outlive us (e.g., when spawning a pager). PIDs are cleared from the kill-list automatically during wait_or_whine, which is called from finish_command and finish_async.

2012-01-06Documentation: rerere.enabled is the primary way to configure rerereLibravatar Thomas Rast1-4/+4
The wording seems to suggest that creating the directory is needed and the setting of rerere.enabled is only for disabling the feature by setting it to 'false'. But the configuration is meant to be the primary control and setting it to 'true' will enable it; the rr-cache directory will be created as necessary and the user does not have to create it.

2012-01-05log --show-signature: reword the common two-head merge caseLibravatar Junio C Hamano1-0/+12
While identifying the commit merged to our history as "parent #2" is technically correct, we will never say "parent #1" (as that is the tip of our history before the merge is made), and we rarely would say "parent #3" (which would mean the merge is an octopus), especially when responding to a request to pull a signed tag. Treat the most common case to merge a single commit specially, and just say "merged tag '<tagname>'" instead. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2012-01-03write first for-merge ref to FETCH_HEAD firstLibravatar Joey Hess25-102/+114
The FETCH_HEAD refname is supposed to refer to the ref that was fetched and should be merged. However all fetched refs are written to .git/FETCH_HEAD in an arbitrary order, and resolve_ref_unsafe simply takes the first ref as the FETCH_HEAD, which is often the wrong one, when other branches were also fetched. The solution is to write the for-merge ref(s) to FETCH_HEAD first. Then, unless --append is used, the FETCH_HEAD refname behaves as intended. If the user uses --append, they presumably are doing so in order to preserve the old FETCH_HEAD. While we are at it, update an old example in the read-tree documentation that implied that each entry in FETCH_HEAD only has the object name, which is not true for quite a while.

2012-01-01stash: Don't fail if work dir contains file named 'HEAD'Libravatar Jonathon Mah4-31/+80
When performing a plain "git stash" (without --patch), git-diff would fail with "fatal: ambiguous argument 'HEAD': both revision and filename". The output was piped into git-update-index, masking the failed exit status. The output is now sent to a temporary file (which is cleaned up by existing code), and the exit status is checked. The "HEAD" arg to the git-diff invocation has been disambiguated too, of course. In patch mode, "git stash -p" would fail harmlessly, leaving the working dir untouched. Interactive adding is fine, but the resulting tree was diffed with an ambiguous 'HEAD' argument. Use >foo (no space) when redirecting output. In t3904, checks and operations on each file are in the order they'll appear when interactively staging. In t3905, fix a bug in "stash save --include-untracked -q is quiet": The redirected stdout file was considered untracked, and so was removed from the working directory. Use test path helper functions where appropriate. Signed-off-by: Jonathon Mah <me@JonathonMah.com> Acked-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Junio C Hamano <gitster@pobox.com>
