Shawn O. Pearce	f43cd49fb8	Change {pre,post}-receive hooks to use stdin Sergey Vlasov, Andy Parkins and Alex Riesen all pointed out that it is possible for a single invocation of receive-pack to be given more refs than the OS might allow us to pass as command line parameters to a single hook invocation. We don't want to break these up into multiple invocations (like xargs might do) as that makes it impossible for the pre-receive hook to verify multiple related ref updates occur at the same time, and it makes it harder for post-receive to send out a single batch notification. Instead we pass the reference data on a pipe connected to the hook's stdin, supplying one ref per line to the hook. This way a single hook invocation can obtain an infinite amount of ref data, without bumping into any operating system limits. Signed-off-by: Shawn O.

Shawn O. Pearce	05ef58ec1f	Teach receive-pack to run pre-receive/post-receive hooks Bill Lear pointed out that it is easy to send out notifications of changes with the update hook, but successful execution of the update hook does not necessarily mean that the ref was actually updated. Lock contention on the ref or being unable to append to the reflog may prevent the ref from being changed. Sending out notifications prior to the ref actually changing is very misleading. To help this situation I am introducing two new hooks to the receive-pack flow: pre-receive and post-receive. These new hooks are invoked only once per receive-pack execution and are passed three arguments per ref (refname, old-sha1, new-sha1). The new post-receive hook is ideal for sending out notifications, as it has the complete list of all refnames that were successfully updated as well as the old and new SHA-1 values. This allows more interesting notifications to be sent. Multiple ref updates could be easily summarized into one email, for example. The new pre-receive hook is ideal for logging update attempts, as it is run only once for the entire receive-pack operation. It can also be used to verify multiple updates happen at once, e.g. an update to the `maint` head must also be accompained by a new annotated tag. Lots of documentation improvements for receive-pack are included in this change, as we want to make sure the new hooks are clearly explained. Signed-off-by: Shawn O.

Johannes Schindelin	5bd74506cd	Get rid of the dependency to GNU diff in the tests Now that "git diff" handles stdin and relative paths outside the working tree correctly, we can convert all instances of "diff -u" to "git diff". This commit is really the result of $ perl -pi.bak -e 's/diff -u/git diff/' $(git grep -l "diff -u" t/) Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net> (cherry picked from commit c699a40d68215c7e44a5b26117a35c8a56fbd387)	18 years ago
Jason Riedy	2aad957a51	Replace "echo -n" with printf in shell scripts. Not all echos know -n. This was causing a test failure in t5401-update-hooks.sh, but not t3800-mktag.sh for some reason.

Shawn O. Pearce	27086d0f84	Add test case for update hooks in receive-pack. Verify that the update hooks work as documented/advertised. This is a simple set of tests to check that the update hooks run with the parameters expected, have their STDOUT and STDERR redirected to the client side of the connection, and that their STDIN does not contain any data (as its actually /dev/null).
