* | Give error when no remote is configuredDaniel Barkalow2009-03-10
|/ | | | | | | | | | | | | | | | | | | | | When there's no explicitly-named remote, we use the remote specified for the current branch, which in turn defaults to "origin". But it this case should require the remote to actually be configured, and not fall back to the path "origin". Possibly, the config file's "remote = something" should require the something to be a configured remote instead of a bare repository URL, but we actually test with a bare repository URL. In fetch, we were giving the sensible error message when coming up with a URL failed, but this wasn't actually reachable, so move that error up and use it when appropriate. In push, we need a new error message, because the old one (formerly unreachable without a lot of help) used the repo name, which was NULL.

* refactor signal handling for cleanup functionsJeff King2009-01-21
| | | | | | | | | | | | | | | | The current code is very inconsistent about which signals are caught for doing cleanup of temporary files and lock files. Some callsites checked only SIGINT, while others checked a variety of death-dealing signals. This patch factors out those signals to a single function, and then calls it everywhere. For some sites, that means this is a simple clean up. For others, it is an improvement in that they will now properly clean themselves up after a larger variety of signals.

* chain kill signals for cleanup functionsJeff King2009-01-21
| | | | | | | | | | | | | | | | | | | | | | | | | If a piece of code wanted to do some cleanup before exiting (e.g., cleaning up a lockfile or a tempfile), our usual strategy was to install a signal handler that did something like this: do_cleanup(); /* actual work */ signal(signo, SIG_DFL); /* restore previous behavior */ raise(signo); /* deliver signal, killing ourselves */ For a single handler, this works fine. However, if we want to clean up two _different_ things, we run into a problem. The most recently installed handler will run, but when it removes itself as a handler, it doesn't put back the first handler. This patch introduces sigchain, a tiny library for handling a stack of signal handlers. You sigchain_push each handler, and use sigchain_pop to restore whoever was before you in the stack.

| * Fix fetch/pull when run without --update-head-okJohannes Schindelin2008-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some confusing tutorials suggested that it would be a good idea to fetch into the current branch with something like this: git fetch origin master:master (or even worse: the same command line with "pull" instead of "fetch"). While it might make sense to store what you want to pull, it typically is plain wrong when the current branch is "master". This should only be allowed when (an incorrect) "git pull origin master:master" tries to work around by giving --update-head-ok to underlying "git fetch", and otherwise we should refuse it, but somewhere along the lines we lost that behavior. The check for the current branch is now _only_ performed in non-bare repositories, which is an improvement from the original behaviour. Some newer tests were depending on the broken behaviour of "git fetch" this patch fixes, and have been adjusted. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Acked-by: Shawn O.

* fetch: give a hint to the user when local refs fail to updateJeff King2008-06-29
| | | | | | | | | | | | | | | | | | | | | | | | There are basically two categories of update failures for local refs: 1. problems outside of git, like disk full, bad permissions, etc. 2. D/F conflicts on tracking branch ref names In either case, there should already have been an error message. In case '1', hopefully enough information has already been given that the user can fix it. In the case of '2', we can hint that the user can clean up their tracking branch area by using 'git remote prune'. Note that we don't actually know _which_ case we have, so the user will receive the hint in case 1, as well. In this case the suggestion won't do any good, but hopefully the user is smart enough to figure out that it's just a hint.

* fetch: report local storage errors in status tableJeff King2008-06-27
| | | | | | | | | | | | | | | | | | | | | | | Previously, if there was an error while storing a local tracking ref, the low-level functions would report an error, but fetch's status output wouldn't indicate any problem. E.g., imagine you have an old "refs/remotes/origin/foo/bar" but upstream has deleted "foo/bar" in favor of a new branch "foo". You would get output like this: error: there are still refs under 'refs/remotes/origin/foo' From $url_of_repo * [new branch] foo -> origin/foo With this patch, the output takes into account the status of updating the local ref: error: there are still refs under 'refs/remotes/origin/foo' From $url_of_repo !

* git-fetch: fix status output when not storing tracking refJeff King2008-04-10
| | | | | | | | | | | | | | | | | | | There was code in update_local_ref for handling this case, but it never actually got called. It assumed that storing in FETCH_HEAD meant a blank peer_ref name, but we actually have a NULL peer_ref in this case, so we never even made it to the update_local_ref function. On top of that, the display formatting was different from all of the other cases, probably owing to the fact that nobody had ever actually seen the output. This patch harmonizes the output with the other cases and moves the detection of this case into store_updated_refs, where we can actually trigger it.

* remote.c: Fix overtight refspec validationJunio C Hamano2008-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * git fetch: Take '-n' to mean '--no-tags'Johannes Schindelin2008-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to commit 8320199 (Rewrite builtin-fetch option parsing to use parse_options().), we understood '-n' as a short option to mean "don't fetch tags from the remote". This patch reinstates behaviour similar, but not identical to the pre commit 8320199 times. Back then, -n always overrode --tags, so if both --tags and -n was given on command-line, no tags were fetched regardless of argument ordering. Now we use a "last entry wins" strategy, so '-n --tags' means "fetch tags". Since it's patently absurd to say both --tags and --no-tags, this shouldn't matter in practice.

* | Teach git-fetch to exploit server side automatic tag followingShawn O. Pearce2008-03-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the remote peer upload-pack process supports the include-tag protocol extension then we can avoid running a second fetch cycle on the client side by letting the server send us the annotated tags along with the objects it is packing for us. In the following graph we can now fetch both "tag1" and "tag2" on the same connection that we fetched "master" from the remote when we only have L available on the local side: T - tag1 S - tag2 / / L - o ------ o ------ B \ \ \ \ origin/master master The objects for "tag1" are implicitly downloaded without our direct knowledge. The existing "quickfetch" optimization within git-fetch discovers that tag1 is complete after the first connection and does not open a second connection. Signed-off-by: Shawn O.

Unfortunately we still cannot nab T at the same time as we are not able to see that T^{} will also be in the range implied by L..B. Such computations must be performed on the remote side (not yet supported) or on the client side as post-processing (the current behavior). This optimization is an extension of the previous one in that it helps on projects which tend to publish both a new commit and a new tag, then lay idle for a while before publishing anything else. Most followers are able to download both the new commit and the new tag in one connection, rather than two. git.git tends to follow such patterns with its roughly once-daily updates from Junio. A protocol extension and additional server side logic would be necessary to also ensure T is grabbed on the first connection. Signed-off-by: Shawn O.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If autofollowing of tags is enabled, we see a new tag on the remote that we don't have, and we already have the SHA-1 object that the tag is peeled to, then we can fetch the tag while we are fetching the other objects on the first connection. This is a slight optimization for projects that have a habit of tagging a release commit after most users have already seen and downloaded that commit object through a prior fetch session. In such cases the users may still find new objects in branch heads, but the new tag will now also be part of the first pack transfer and the subsequent connection to autofollow tags is not required. Currently git.git does not benefit from this optimization as any release usually gets a new commit at the same time that it gets a new release tag, however git-gui.git and many other projects are in the habit of tagging fairly old commits. Users who did not already have the tagged commit still require opening a second connection to autofollow the tag, as we are unable to determine on the client side if $tag^{} will be sent to the client during the first transfer or not. Such computation must be performed on the remote side of the connection and is deferred to another series of changes. Signed-off-by: Shawn O.

The url in git_connect should be const (and work on a copy) instead of requiring the caller to copy it. match_refs doesn't modify the refspecs it gets. get_fetch_map and get_remote_ref don't change the list they get. Allow transport get_refs_list methods to modify the struct transport. Add a function to copy a list of refs, when a function needs a mutable copy of a const list. Add a function to check the type of a ref, as per the code in connect.c Signed-off-by: Daniel Barkalow <barkalow@iabervon.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

In such a case there is no reason to copy any objects as we can already obtain them through the alternate. However we need to ensure the objects are all reachable, so we run `git rev-list --objects $theirs --not --all` to verify this. If any object is missing or unreadable then we need to fetch/copy the objects from the remote. When a missing object is detected the git-rev-list process will exit with a non-zero exit status, making this condition quite easy to detect. Although git-fetch is currently a builtin (and so is rev-list) we cannot invoke the traverse_objects() API at this point in the transport code. The object walker within traverse_objects() calls die() as soon as it finds an object it cannot read. If that happens we want to resume the fetch process by calling do_fetch_pack(). To get around this we spawn git-rev-list into a background process to prevent a die() from killing the foreground fetch process, thus allowing the fetch process to resume into do_fetch_pack() if copying is necessary. We aren't interested in the output of rev-list (a list of SHA-1 object names that are reachable) or its errors (a "spurious" error about an object not being found as we need to copy it) so we redirect both stdout and stderr to /dev/null. We run this git-rev-list based check before any fetch as we may already have the necessary objects local from a prior fetch. If we don't then its very likely the first $theirs object listed on the command line won't exist locally and git-rev-list will die very quickly, allowing us to start the network transfer. This test even on remote URLs may save bandwidth if someone runs `git pull origin`, sees a merge conflict, resets out, then redoes the same pull just a short time later. If the remote hasn't changed between the two pulls and the local repository hasn't had git-gc run in it then there is probably no need to perform network transfer as all of the objects are local. Documentation for the new quickfetch function was suggested and written by Junio, based on his original comment in git-fetch.sh. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
| * | | git-fetch: Always fetch tags if the object they reference existsShawn O. Pearce2007-11-11
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously git-fetch.sh used `git cat-file -t` to determine if an object referenced by a tag exists, and if so fetch that tag locally. This was subtly broken during the port to C based builtin-fetch as lookup_object() only works to locate an object if it was previously accessed by the transport. Not all transports will access all objects in this way, so tags were not always being fetched. The rsync transport never loads objects into the internal object table so automated tag following didn't work if rsync was used. Automated tag following also didn't work on the native transport if the new tag was behind the common point(s) negotiated between the two ends of the connection as the tag's referrant would not be loaded into the internal object table. Further the automated tag following was broken with the HTTP commit walker if the new tag's referrant was behind an existing ref, as the walker would stop before loading the tag's referrant into the object table. Switching to has_sha1_file() restores the original behavior from the shell script by checking if the object exists in the ODB, without relying on the state left behind by a transport.
