* Teach fetch-pack/upload-pack about --include-tagShawn O. Pearce2008-03-04
| | | | | | | | | | | | The new protocol extension "include-tag" allows the client side of the connection (fetch-pack) to request that the server side of the native git protocol (upload-pack / pack-objects) use --include-tag as it prepares the packfile, thus ensuring that an annotated tag object will be included in the resulting packfile if the object it refers to was also included into the packfile.

* upload-pack: Initialize the exec-path.Johannes Sixt2008-02-13
| | | | | | | | | | | Since git-upload-pack has to spawn git-pack-objects, it has to make sure that the latter can be found in the PATH. Without this patch an attempt to clone or pull via ssh from a server fails if the git tools are not in the standard PATH on the server even though git clone or git pull were invoked with --upload-pack=/path/to/git-upload-pack.

* upload-pack: Use finish_{command,async}() instead of waitpid().Johannes Sixt2007-11-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | upload-pack spawns two processes, rev-list and pack-objects, and carefully monitors their status so that it can report failure to the remote end. This change removes the complicated procedures on the grounds of the following observations: - If everything is OK, rev-list closes its output pipe end, upon which pack-objects (which reads from the pipe) sees EOF and terminates itself, closing its output (and error) pipes. upload-pack reads from both until it sees EOF in both. It collects the exit codes of the child processes (which indicate success) and terminates successfully. - If rev-list sees an error, it closes its output and terminates with failure. pack-objects sees EOF in its input and terminates successfully. Again upload-pack reads its inputs until EOF. When it now collects the exit codes of its child processes, it notices the failure of rev-list and signals failure to the remote end. - If pack-objects sees an error, it terminates with failure. Since this breaks the pipe to rev-list, rev-list is killed with SIGPIPE. upload-pack reads its input until EOF, then collects the exit codes of the child processes, notices their failures, and signals failure to the remote end. - If upload-pack itself dies unexpectedly, pack-objects is killed with SIGPIPE, and subsequently also rev-list. The upshot of this is that precise monitoring of child processes is not required because both terminate if either one of them dies unexpectedly. This allows us to use finish_command() and finish_async() instead of an explicit waitpid(2) call. The change is smaller than it looks because most of it only reduces the indentation of a large part of the inner loop.

| | | | | | | | | | | This gets rid of an explicit fork().

* git-upload-pack: make sure we close unused pipe endsH. Peter Anvin2007-03-27
| | | | | | | | | | | | | | | | | Right now, we don't close the read end of the pipe when git-upload-pack runs git-pack-object, so we hang forever (why don't we get SIGALRM?) instead of dying with SIGPIPE if the latter dies, which seems to be the norm if the client disconnects.

| * Fixup no-progress for fetch & cloneJohannes Schindelin2007-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The intent of the commit 'fetch & clone: do not output progress when not on a tty' was to make fetching and cloning less chatty when output was not redirected (such as in a cron job). However, there was a serious thinko in that commit. It assumed that the client _and_ the server got this update at the same time. But this is obviously not the case, and therefore upload-pack died on seeing the option "--no-progress". This patch fixes that issue by making it a protocol option. So, until your server is updated, you still see the progress, but once the server has this patch, it will be quiet. A minor issue was also fixed: when cloning, the checkout did not heed no_progress.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A shallow commit is a commit which has parents, which in turn are "grafted away", i.e. the commit appears as if it were a root. Since these shallow commits should not be edited by the user, but only by core git, they are recorded in the file $GIT_DIR/shallow. A repository containing shallow commits is called shallow. The advantage of a shallow repository is that even if the upstream contains lots of history, your local (shallow) repository needs not occupy much disk space. The disadvantage is that you might miss a merge base when pulling some remote branch. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>
