2011-12-13Rename resolve_ref() to resolve_ref_unsafe()Libravatar Nguyễn Thái Ngọc Duy1-3/+3
resolve_ref() may return a pointer to a shared buffer and can be overwritten by the next resolve_ref() calls. Callers need to pay attention, not to keep the pointer when the next call happens. Rename with "_unsafe" suffix to warn developers (or reviewers) before introducing new call sites. This patch is generated using the following command git grep -l 'resolve_ref(' -- '*.[ch]'|xargs sed -i 's/resolve_ref(/resolve_ref_unsafe(/g' Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-11-13Convert many resolve_ref() calls to read_ref*() and ref_exists()Libravatar Nguyễn Thái Ngọc Duy1-2/+2
resolve_ref() may return a pointer to a static buffer, which is not safe for long-term use because if another resolve_ref() call happens, the buffer may be changed. Many call sites though do not care about this buffer. They simply check if the return value is NULL or not. Convert all these call sites to new wrappers to reduce resolve_ref() calls from 57 to 34. If we change resolve_ref() prototype later on to avoid passing static buffer out, this helps reduce changes.

2011-10-15fetch: honor the user-provided refspecs when pruning refsLibravatar Carlos Martín Nieto1-12/+23
If the user gave us refspecs on the command line, we should use those when deciding whether to prune a ref instead of relying on the refspecs in the config. Previously, running git fetch --prune origin refs/heads/master:refs/remotes/origin/master would delete every other ref under the origin namespace because we were using the refspec to filter the available refs but using the configured refspec to figure out if a ref had been deleted on the remote. This is clearly the wrong thing to do. Change prune_refs and get_stale_heads to simply accept a list of references and a list of refspecs. The caller of either function needs to decide what refspecs should be used to decide whether a ref is stale.

2011-10-15remote: separate out the remote_find_tracking logic into query_refspecsLibravatar Carlos Martín Nieto1-36/+33
Move the body of remote_find_tracking() to a new helper query_refspecs() that finds a refspec that matches and applies the transformation, but explicitly takes the list of refspecs, and make remote_find_tracking() a thin wrapper of it. Make apply_refspecs() also use query_refspecs(). Signed-off-by: Carlos Martín Nieto <cmn@elego.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-10-05Change check_ref_format() to take a flags argumentLibravatar Michael Haggerty1-39/+14
Change check_ref_format() to take a flags argument that indicates what is acceptable in the reference name (analogous to "git check-ref-format"'s "--allow-onelevel" and "--refspec-pattern"). This is more convenient for callers and also fixes a failure in the test suite (and likely elsewhere in the code) by enabling "onelevel" and "refspec-pattern" to be allowed independently of each other. Also rename check_ref_format() to check_refname_format() to make it obvious that it deals with refnames rather than references themselves.

2011-06-05consider only branches in guess_remote_headLibravatar Jeff King1-1/+3
The guess_remote_head function tries to figure out where a remote's HEAD is pointing by comparing the sha1 of the remote's HEAD with the sha1 of various refs found on the remote. However, we were too liberal in matching refs, and would match tags or remote tracking branches, even though these things could not possibly be referenced by the HEAD symbolic ref (since git will detach when checking them out). As a result, a clone of a remote repository with a detached HEAD might write "refs/tags/*" into our local HEAD, which is bogus. The resulting HEAD should be detached. The other related code path is remote.c's get_head_names() (which is used for, among other things, "set-head -a"). This was not affected, however, as that function feeds only refs from refs/heads to guess_remote_head. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2010-01-09refactor ref status logic for pushingLibravatar Tay Ray Chuan1-0/+50
Move the logic that detects up-to-date and non-fast-forward refs to a new function in remote.[ch], set_ref_status_for_push(). Make transport_push() invoke set_ref_status_for_push() before invoking the push_refs() implementation. (As a side-effect, the push_refs() implementation in transport-helper.c now knows of non-fast-forward pushes.) Removed logic for detecting up-to-date refs from the push_refs() implementation in transport-helper.c, as transport_push() has already done so for it. Make cmd_send_pack() invoke set_ref_status_for_push() before invoking send_pack(), as transport_push() can't do it for send_pack() here. Mark the test on the return status of non-fast-forward push to fail. Git now exits with success, as transport.c::transport_push() does not check for refs with status REF_STATUS_REJECT_NONFASTFORWARD nor does it indicate rejected pushes with its return value. Mark the test for ref status to succeed. As mentioned earlier, refs might be marked as non-fast-forwards, triggering the push status printing mechanism in transport.c.

2009-11-17Add a config option for remotes to specify a foreign vcsLibravatar Daniel Barkalow1-1/+3
If this is set, the url is not required, and the transport always uses a helper named "git-remote-<value>". It is a separate configuration option in order to allow a sensible configuration for foreign systems which either have no meaningful urls for repositories or which require urls that do not specify the system used by the repository at that location. However, this only affects how the name of the helper is determined, not anything about the interaction with the helper, and the contruction is such that, if the foreign scm does happen to use a co-named url method, a url with that method may be used directly.

2009-10-27remote: Make ref_remove_duplicates faster for large numbers of refsLibravatar Julian Phillips1-19/+22
The ref_remove_duplicates function was very slow at dealing with very large numbers of refs.

2009-09-08Add url.<base>.pushInsteadOf: URL rewriting for push onlyLibravatar Josh Triplett1-9/+27
This configuration option allows systematically rewriting fetch-only URLs to push-capable URLs when used with push.

2009-06-20Fix various sparse warnings in the git source codeLibravatar Linus Torvalds1-3/+3
There are a few remaining ones, but this fixes the trivial ones. It boils down to two main issues that sparse complains about: - warning: Using plain integer as NULL pointer Sparse doesn't like you using '0' instead of 'NULL'. For various good reasons, not the least of which is just the visual confusion. A NULL pointer is not an integer, and that whole "0 works as NULL" is a historical accident and not very pretty. A few of these remain: zlib is a total mess, and Z_NULL is just a 0. I didn't touch those. - warning: symbol 'xyz' was not declared. Should it be static? Sparse wants to see declarations for any functions you export. A lack of a declaration tends to mean that you should either add one, or you should mark the function 'static' to show that it's in file scope. A few of these remain: I only did the ones that should obviously just be made static. That 'wt_status_submodule_summary' one is debatable. It has a few related flags (like 'wt_status_use_color') which _are_ declared, and are used by builtin-commit.c. So maybe we'd like to export it at some point, but it's not declared now, and not used outside of that file, so 'static' it is in this patch.

2009-05-14Fix behavior with non-commit upstream referencesLibravatar Michael J Gruber1-2/+2
stat_tracking_info() assumes that upstream references (as specified by --track or set up automatically) are commits. By calling lookup_commit() on them, create_objects() creates objects for them with type commit no matter what their real type is; this disturbs lookup_tag() later on in the call sequence, leading to git status, git branch -v and git checkout erroring out. Fix this by using lookup_commit_reference() instead so that (annotated) tags can be used as upstream references.
