2008-05-04add special "matching refs" refspecLibravatar Paolo Bonzini1-1/+9
This patch provides a way to specify "push matching heads" using a special refspec ":". This is useful because it allows "push = +:" as a way to specify that matching refs will be pushed but, in addition, forced updates will be allowed, which was not possible before.

2008-03-22remote.c: Fix overtight refspec validationLibravatar Junio C Hamano1-1/+1
We tightened the refspec validation code in an earlier commit ef00d15 (Tighten refspec processing, 2008-03-17) per my suggestion, but the suggestion was misguided to begin with and it broke this usage: $ git push origin HEAD~12:master The syntax of push refspecs and fetch refspecs are similar in that they are both colon separated LHS and RHS (possibly prefixed with a + to force), but the similarity ends there. For example, LHS in a push refspec can be anything that evaluates to a valid object name at runtime (except when colon and RHS is missing, or it is a glob), while it must be a valid-looking refname in a fetch refspec. To validate them correctly, the caller needs to be able to say which kind of refspecs they are. It is unreasonable to keep a single interface that cannot tell which kind it is dealing with, and ask it to behave sensibly. This commit separates the parsing of the two into different functions, and clarifies the code to implement the parsing proper (i.e. splitting into two parts, making sure both sides are wildcard or neither side is). This happens to also allow pushing a commit named with the esoteric "look for that string" syntax: $ git push ../test.git ':/remote.c: Fix overtight refspec:master' Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-03-01Clean up find_unique_abbrev() callersLibravatar Junio C Hamano1-3/+1
Now find_unique_abbrev() never returns NULL, there is no need for callers to prepare for seeing NULL and fall back to giving the full 40-hexdigits. While we are at it, drop "..." in the "git reset" output that reports the location of the new HEAD, between the abbreviated commit object name and the one line commit summary. Because we are always showing the HEAD (which cannot be missing!), we never had a case where we show the full 40 hexdigits that is not followed by three dots, and these three dots were stealing 3 columns from the precious horizontal screen real estate out of 80 that can better be used for the one line commit summary.

2008-02-23start_command(), if .in/.out > 0, closes file descriptors, not the callersLibravatar Johannes Sixt1-6/+8
Callers of start_command() can set the members .in and .out of struct child_process to a value > 0 to specify that this descriptor is used as the stdin or stdout of the child process. Previously, if start_command() was successful, this descriptor was closed upon return. Here we now make sure that the descriptor is also closed in case of failures. All callers are updated not to close the file descriptor themselves after start_command() was called. Note that earlier run_gpg_verify() of git-verify-tag set .out = 1, which worked because start_command() treated this as a special case, but now this is incorrect because it closes the descriptor. The intent here is to inherit stdout to the child, which is achieved by .out = 0. Signed-off-by: Johannes Sixt <johannes.sixt@telecom.at> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-02-23start_command(), .in/.out/.err = -1: Callers must close the file descriptorLibravatar Johannes Sixt1-0/+1
By setting .in, .out, or .err members of struct child_process to -1, the callers of start_command() can request that a pipe is allocated that talks to the child process and one end is returned by replacing -1 with the file descriptor. Previously, a flag was set (for .in and .out, but not .err) to signal finish_command() to close the pipe end that start_command() had handed out, so it was optional for callers to close the pipe, and many already do so. Now we make it mandatory to close the pipe. Signed-off-by: Johannes Sixt <johannes.sixt@telecom.at> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-01-02Update callers of check_ref_format()Libravatar Junio C Hamano1-4/+6
This updates send-pack and fast-import to use symbolic constants for checking the return values from check_ref_format(), and also futureproof the logic in lock_any_ref_for_update() to explicitly name the case that is usually considered an error but is Ok for this particular use.

2007-11-20send-pack: cluster ref status reportingLibravatar Jeff King1-40/+53
Instead of intermingling success and failure, we now print: 1. all uptodate refs (if args.verbose is enabled) 2. successfully pushed refs 3. failed refs with the assumption that the user is most likely to see the ones at the end, and therefore we order them from "least interesting" to "most interesting."

2007-11-18send-pack: fix "everything up-to-date" messageLibravatar Jeff King1-1/+15
This has always been slightly inaccurate, since it used the new_refs counter, which really meant "did we send any objects," so deletions were not counted. It has gotten even worse with recent patches, since we no longer look at the 'ret' value, meaning we would say "up to date" if non-ff pushes were rejected. Instead, we now claim up to date iff every ref is either unmatched or up to date. Any other case should already have generated a status line.

2007-11-18send-pack: tighten remote error reportingLibravatar Jeff King1-42/+52
Previously, we set all ref pushes to 'OK', and then marked them as errors if the remote reported so. This has the problem that if the remote dies or fails to report a ref, we just assume it was OK. Instead, we use a new non-OK state to indicate that we are expecting status (if the remote doesn't support the report-status feature, we fall back on the old behavior). Thus we can flag refs for which we expected a status, but got none (conversely, we now also print a warning for refs for which we get a status, but weren't expecting one). This also allows us to simplify the receive_status exit code, since each ref is individually marked with failure until we get a success response. We can just print the usual status table, so the user still gets a sense of what we were trying to do when the failure happened.

2007-11-17send-pack: assign remote errors to each refLibravatar Jeff King1-6/+45
This lets us show remote errors (e.g., a denied hook) along with the usual push output. There is a slightly clever optimization in receive_status that bears explanation. We need to correlate the returned status and our ref objects, which naively could be an O(m*n) operation. However, since the current implementation of receive-pack returns the errors to us in the same order that we sent them, we optimistically look for the next ref to be looked up to come after the last one we have found. So it should be an O(m+n) merge if the receive-pack behavior holds, but we fall back to a correct but slower behavior if it should change.

2007-11-17send-pack: check ref->status before updating tracking refsLibravatar Jeff King1-13/+5
Previously, we manually checked the 'NONE' and 'UPTODATE' conditions. Now that we have ref->status, we can easily say "only update if we pushed successfully". This adds a test for and fixes a regression introduced in ed31df31 where deleted refs did not have their tracking branches removed. This was due to a bogus per-ref error test that is superseded by the more accurate ref->status flag.

2007-11-17send-pack: track errors for each refLibravatar Jeff King1-90/+134
Instead of keeping the 'ret' variable, we instead have a status flag for each ref that tracks what happened to it. We then print the ref status after all of the refs have been examined. This paves the way for three improvements: - updating tracking refs only for non-error refs - incorporating remote rejection into the printed status - printing errors in a different order than we processed (e.g., consolidating non-ff errors near the end with a special message) Signed-off-by: Jeff King <peff@peff.net> Acked-by: Alex Riesen <raa.lkml@gmail.com> Acked-by: Daniel Barkalow <barkalow@iabervon.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2007-11-09Teach send-pack a mirror modeLibravatar Andy Whitcroft1-12/+34
Existing "git push --all" is almost perfect for backing up to another repository, except that "--all" only means "all branches" in modern git, and it does not delete old branches and tags that exist at the back-up repository that you have removed from your local repository. This teaches "git-send-pack" a new "--mirror" option. The difference from the "--all" option are that (1) it sends all refs, not just branches, and (2) it deletes old refs you no longer have on the local side from the remote side.

2007-11-08send-pack: segfault fix on forced pushLibravatar Junio C Hamano1-2/+3
When pushing to overwrite a ref that points at a commit we do not even have, the recent "terse push" patch tried to get a unique abbreviation for the non-existent (from our point of view) object, which resulted in strcpy(buf, NULL) and segfaulted. Signed-off-by: Junio C Hamano <gitster@pobox.com>
