2008-03-26Tighten refspec processingLibravatar Daniel Barkalow1-39/+137
This changes the pattern matching code to not store the required final / before the *, and then to require each side to be a valid ref (or empty). In particular, any refspec that looks like it should be a pattern but doesn't quite meet the requirements will be found to be invalid as a fallback non-pattern. This was cherry picked from commit ef00d15 (Tighten refspec processing, 2008-03-17), and two fix-up commits 46220ca (remote.c: Fix overtight refspec validation, 2008-03-20) and 7d19da4 (refspec: allow colon-less wildcard "refs/category/*", 2008-03-25) squashed in.

2008-03-25refspec: allow colon-less wildcard "refs/category/*"Libravatar Junio C Hamano1-7/+11
"git push --tags elsewhere" is implemented in terms of wildcarded refspec "refs/tags/*" these days, and the user wants to push the tags under the same name to the other branch. This resurrects the support for it. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-03-22remote.c: Fix overtight refspec validationLibravatar Junio C Hamano1-46/+111
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>

2008-02-24url rewriting: take longest and first matchLibravatar Junio C Hamano1-16/+38
Earlier we had a cop-out in the documentation to make the behaviour "undefined" if configuration had more than one insteadOf that would match the target URL, like this: [url "git://git.or.cz/"] insteadOf = "git.or.cz:" ; (1) insteadOf = "repo.or.cz:" ; (2) [url "/local/mirror/"] insteadOf = "git.or.cz:myrepo" ; (3) insteadOf = "repo.or.cz:" ; (4) It would be most natural to take the longest and first match, i.e. - rewrite "git.or.cz:frotz" to "git://git.or.cz/frotz" by using (1), - rewrite "git.or.cz:myrepo/xyzzy" to "/local/mirror/xyzzy" by favoring (3) over (1), and - rewrite "repo.or.cz:frotz" to "git://git.or.cz/frotz" by favoring (2) over (4).

2008-02-24Add support for url aliases in config filesLibravatar Daniel Barkalow1-3/+94
This allows users with different preferences for access methods to the same remote repositories to rewrite each other's URLs by pattern matching across a large set of similiarly set up repositories to each get the desired access. For example, if you don't have a kernel.org account, you might want settings like: [url "git://git.kernel.org/pub/"] insteadOf = master.kernel.org:/pub Then, if you give git a URL like: master.kernel.org:/pub/scm/linux/kernel/git/linville/wireless-2.6.git it will act like you gave it: git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-2.6.git and you can cut-and-paste pull requests in email without fixing them by hand, for example.

2008-02-22Avoid unnecessary "if-before-free" tests.Libravatar Jim Meyering1-2/+1
This change removes all obvious useless if-before-free tests. E.g., it replaces code like this: if (some_expression) free (some_expression); with the now-equivalent: free (some_expression); It is equivalent not just because POSIX has required free(NULL) to work for a long time, but simply because it has worked for so long that no reasonable porting target fails the test. Here's some evidence from nearly 1.5 years ago: http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html FYI, the change below was prepared by running the following: git ls-files -z | xargs -0 \ perl -0x3b -pi -e \ 's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s' Note however, that it doesn't handle brace-enclosed blocks like "if (x) { free (x); }". But that's ok, since there were none like that in git sources. Beware: if you do use the above snippet, note that it can produce syntactically invalid C code. That happens when the affected "if"-statement has a matching "else". E.g., it would transform this if (x) free (x); else foo (); into this: free (x); else foo (); There were none of those here, either. If you're interested in automating detection of the useless tests, you might like the useless-if-before-free script in gnulib: [it *does* detect brace-enclosed free statements, and has a --name=S option to make it detect free-like functions with different names] http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=build-aux/useless-if-before-free Addendum: Remove one more (in imap-send.c), spotted by Jean-Luc Herren <jlh@gmx.ch>.

2008-02-20Resolve value supplied for no-colon push refspecsLibravatar Daniel Barkalow1-1/+9
When pushing a refspec like "HEAD", we used to treat it as "HEAD:HEAD", which didn't work without rewriting. Instead, we should resolve the ref. If it's a symref, further require it to point to a branch, to avoid doing anything especially unexpected. Also remove the rewriting previously added in builtin-push. Since the code for "HEAD" uses the regular refspec parsing, it automatically handles "+HEAD" without anything special.

2008-02-15Validate nicknames of remote branches to prohibit confusing onesLibravatar Daniel Barkalow1-1/+11
The original problem was that the parsers for configuration files were getting confused by seeing as nicknames remotes that involved directory-changing characters.

2007-11-18refactor fetch's ref matching to use refname_match()Libravatar Steffen Prohaska1-21/+2
The old rules used by fetch were coded as a series of ifs. The old rules are: 1) match full refname if it starts with "refs/" or matches "HEAD" 2) verify that full refname starts with "refs/" 3) match abbreviated name in "refs/" if it starts with "heads/", "tags/", or "remotes/". 4) match abbreviated name in "refs/heads/" This is replaced by the new rules a) match full refname b) match abbreviated name prefixed with "refs/" c) match abbreviated name prefixed with "refs/heads/" The details of the new rules are different from the old rules. We no longer verify that the full refname starts with "refs/". The new rule (a) matches any full string. The old rules (1) and (2) were stricter. Now, the caller is responsible for using sensible full refnames. This should be the case for the current code. The new rule (b) is less strict than old rule (3). The new rule accepts abbreviated names that start with a non-standard prefix below "refs/". Despite this modifications the new rules should handle all cases as expected. Two tests are added to verify that fetch does not resolve short tags or HEAD in remotes. We may even think about loosening the rules a bit more and unify them with the rev-parse rules. This would be done by replacing ref_ref_fetch_rules with ref_ref_parse_rules. Note, the two new test would break.

2007-11-18push: use same rules as git-rev-parse to resolve refspecsLibravatar Steffen Prohaska1-4/+1
This commit changes the rules for resolving refspecs to match the rules for resolving refs in rev-parse. git-rev-parse uses clear rules to resolve a short ref to its full name, which are well documented. The rules for resolving refspecs documented in git-send-pack were less strict and harder to understand. This commit replaces them by the rules of git-rev-parse. The unified rules are easier to understand and better resolve ambiguous cases. You can now push from a repository containing several branches ending on the same short name. Note, this may break existing setups. For example, "master" will no longer resolve to "origin/master" even when there is no other "master" elsewhere.

2007-11-09Teach send-pack a mirror modeLibravatar Andy Whitcroft1-5/+10
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.

2007-10-28git-fetch: do not fail when remote branch disappearsLibravatar Junio C Hamano1-9/+13
When the branch named with branch.$name.merge is not covered by the fetch configuration for the remote repository named with branch.$name.remote, we automatically add that branch to the set of branches to be fetched. However, if the remote repository does not have that branch (e.g. it used to exist, but got removed), this is not a reason to fail the git-fetch itself. The situation however will be noticed if git-fetch was called by git-pull, as the resulting FETCH_HEAD would not have any entry that is marked for merging.

2007-09-19Correct handling of branch.$name.merge in builtin-fetchLibravatar Shawn O. Pearce1-8/+5
My prior bug fix for git-push titled "Don't configure remote "." to fetch everything to itself" actually broke t5520 as we were unable to evaluate a branch configuration of: [branch "copy"] remote = . merge = refs/heads/master as remote "." did not have a "remote...fetch" configuration entry to offer up refs/heads/master as a possible candidate available to be fetched and merged. In shell script git-fetch and prior to the above mentioned commit this was hardcoded for a url of "." to be the set of local branches. Chasing down this bug led me to the conclusion that our prior behavior with regards to branch.$name.merge was incorrect. In the shell script based git-fetch implementation we only fetched and merged a branch if it appeared both in branch.$name.merge *and* in remote.$r.fetch, where $r = branch.$name.remote. In other words in the following config file: [remote "origin"] url = git://git.kernel.org/pub/scm/git/git.git fetch = refs/heads/master:refs/remotes/origin/master [branch "master"] remote = origin merge = refs/heads/master [branch "pu"] remote = origin merge = refs/heads/pu Attempting to run `git pull` while on branch "pu" would always give the user "Already up-to-date" as git-fetch did not fetch pu and thus did not mark it for merge in .git/FETCH_HEAD. The configured merge would always be ignored and the user would be left scratching her confused head wondering why merge did not work on "pu" but worked fine on "master". If we are using the "default fetch" specification for the current branch and the current branch has a branch.$name.merge configured we now union it with the list of refs in remote.$r.fetch. This way the above configuration does what the user expects it to do, which is to fetch only "master" by default but when on "pu" to fetch both "master" and "pu". This uncovered some breakage in the test suite where old-style Cogito branches (.git/branches/$r) did not fetch the branches listed in .git/config for merging and thus did not actually merge them if the user tried to use `git pull` on that branch. Junio and I discussed it on list and felt that the union approach here makes more sense to DWIM for the end-user than silently ignoring their configured request so the test vectors for t5515 have been updated to include for-merge lines in .git/FETCH_HEAD where they have been configured for-merge in .git/config. Since we are now performing a union of the fetch specification and the merge specification and we cannot allow a branch to be listed twice (otherwise it comes out twice in .git/FETCH_HEAD) we need to perform a double loop here over all of the branch.$name.merge lines and try to set their merge flag if we have already schedule that branch for fetching by remote.$r.fetch. If no match is found then we must add new specifications to fetch the branch but not store it as no local tracking branch has been designated. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>

2007-09-19Don't configure remote "." to fetch everything to itselfLibravatar Shawn O. Pearce1-4/+0
When we are talking about a remote URI of "." we are really talking about *this* repository that we are fetching into or pushing out of. There are no matching tracking branches for this repository; we do not attempt to map a ref back to ourselves as this would either create an infinite cycle (for example "fetch = +refs/*:refs/mine/*") or it causes problems when we attempt to push back to ourselves. So we really cannot setup a remote like this: [remote "."] url = . fetch = +refs/*:refs/* In the case of `git push . B:T` to fast-forward branch T to B's current commit git-send-pack will update branch T to B, assuming that T is the remote tracking branch for B. This update is performed immediately before git-send-pack asks git-receive-pack to perform the same update, and git-receive-pack then fails because T is not where git-send-pack told it to expect T to be at. In the case of `git fetch .` we really should do the same thing as `git fetch $otherrepo`, that is load .git/FETCH_HEAD with the commit of HEAD, so that `git pull .` will report "Already up-to-date". We have always behaved like this before on this insane request and we should at least continue to behave the same way. With the above (bad) remote configuration we were instead getting fetch errors about funny refs, e.g. "refs/stash". Signed-off-by: Shawn O.

2007-06-12Don't dereference a strdup-returned NULLLibravatar Jim Meyering1-1/+1
There are only a dozen or so uses of strdup in all of git. Of those, most seem ok, but this one isn't: Signed-off-by: Jim Meyering <jim@meyering.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-06-09remote.c: "git-push frotz" should update what matches at the source.Libravatar Junio C Hamano1-6/+1
Earlier, when the local repository has a branch "frotz" and the remote repository has a tag "frotz" (but not branch "frotz"), "git-push frotz" mistakenly updated the tag at the remote side. This was because the partial refname matching code was applied independently on both source and destination side. With this fix, when a colon-less refspec is given to git-push, we first match it with the refs in the source repository, and update the matching ref in the destination repository.

2007-06-09remote.c: fix "git push" weak match disambiguationLibravatar Junio C Hamano1-1/+0
When "git push A:B" is given, and A (or B) is not a full refname that begins with refs/, we require an unambiguous match with an existing ref. For this purpose, a match with a local branch or a tag (i.e. refs/heads/A and refs/tags/A) is called a "strong match", and any other match is called a "weak match". A partial refname is unambiguous when there is only one strong match with any number of weak matches, or when there is only one weak match and no other match. However, as reported by Sparse with Ramsay Jones recently, count_refspec_match() function had a bug where a variable in an inner block masked a different variable of the same name, which caused the weak matches to be ignored. This fixes it, and adds tests for the fix. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2007-06-09remote.c: minor clean-up of match_explicit()Libravatar Junio C Hamano1-11/+12
When checking what ref the source refspec matches, we have no business setting the default for the destination, so move that code lower. Also simplify the result from the code block that matches the source side by making it set matched_src only upon unambiguous match. Signed-off-by: Junio C Hamano <gitster@pobox.com>
