2014-06-16Merge branch 'jl/remote-rm-prune'Junio C Hamano
"git remote rm" and "git remote prune" can involve removing many refs at once, which is not a very efficient thing to do when very many refs exist in the packed-refs file. * jl/remote-rm-prune: remote prune: optimize "dangling symref" check/warning remote: repack packed-refs once when deleting multiple refs remote rm: delete remote configuration as the last

2014-05-27remote prune: optimize "dangling symref" check/warningJens Lindström
When 'git remote prune' was used to delete many refs in a repository with many refs, a lot of time was spent checking for (now) dangling symbolic refs pointing to the deleted ref, since warn_dangling_symref() was once per deleted ref to check all other refs in the repository. Avoid this using the new warn_dangling_symrefs() function which makes one pass over all refs and checks for all the deleted refs in one go, after they have all been deleted.

2014-05-27remote: repack packed-refs once when deleting multiple refsJens Lindström
When 'git remote rm' or 'git remote prune' were used in a repository with many refs, and needed to delete many remote-tracking refs, a lot of time was spent deleting those refs since for each deleted ref, repack_without_refs() was called to rewrite packed-refs without just that deleted ref. To avoid this, call repack_without_refs() first to repack without all the refs that will be deleted, before calling delete_ref() to delete each one completely. The call to repack_without_ref() in delete_ref() then becomes a no-op, since packed-refs already won't contain any of the deleted refs.

2014-05-09refs.c: add new functions reflog_exists and delete_reflogRonnie Sahlberg
Add two new functions, reflog_exists and delete_reflog, to hide the internal reflog implementation (that they are files under .git/logs/...) from callers. Update checkout.c to use these functions in update_refs_for_switch instead of building pathnames and calling out to file access functions. Update reflog.c to use these to check if the reflog exists. Now there are still many places in reflog.c where we are still leaking the reflog storage implementation but this at least reduces the number of such dependencies by one. Finally change two places in refs.c itself to use the new function to check if a ref exists or not isntead of build-path-and-stat(). Now, this is strictly not all that important since these are in parts of refs that are implementing the actual file storage backend but on the other hand it will not hurt either.

2014-04-07update_refs(): fix constnessMichael Haggerty
The old signature of update_refs() required a (const struct ref_update **) for its updates_orig argument. The "const" is presumably there to promise that the function will not modify the contents of the structures. But this declaration does not permit the function to be called with a (struct ref_update **), which is perfectly legitimate. C's type system is not powerful enough to express what we'd like. So remove the first "const" from the declaration. On the other hand, the function *can* promise not to modify the pointers within the array that is passed to it without inconveniencing its callers. So add a "const" that has that effect, making the final declaration (struct ref_update * const *).

2014-04-07refs.h: rename the action_on_err constantsMichael Haggerty

2013-09-04refs: add update_refs for multiple simultaneous updatesBrad King
Add 'struct ref_update' to encode the information needed to update or delete a ref (name, new sha1, optional old sha1, no-deref flag). Add function 'update_refs' accepting an array of updates to perform. First sort the input array to order locks consistently everywhere and reject multiple updates to the same ref. Then acquire locks on all refs with verified old values. Then update or delete all refs accordingly. Fail if any one lock cannot be obtained or any one old value does not match. Though the refs themselves cannot be modified together in a single atomic transaction, this function does enable some useful semantics. For example, a caller may create a new branch starting from the head of another branch and rewind the original branch at the same time. This transfers ownership of commits between branches without risk of losing commits added to the original branch by a concurrent process, or risk of a concurrent process creating the new branch first.

2013-06-03refs: document the lifetime of the args passed to each_ref_fnMichael Haggerty
The lifetime of the memory pointed to by the refname and sha1 arguments to each_ref_fn was never documented, but some callers used to assume that it was essentially permanent. In fact the API does *not* guarantee that these objects live beyond a single callback invocation. In the current code, the lifetimes are bound together with the lifetimes of the ref_caches. Since these are usually long, the callers usually got away with their sloppiness. But even today, if a ref_cache is invalidated the memory can be freed. And planned changes to reference caching, needed to eliminate race conditions, will probably need to shorten the lifetimes of these objects. The commits leading up to this have (hopefully) fixed all of the callers of the for_each_ref()-like functions. This commit does the last step: documents what each_ref_fn callbacks can assume about object lifetimes.

2013-05-02peel_ref(): fix return value for non-peelable, not-current referenceMichael Haggerty

Change the behavior for non-current references to match that of current_ref, which is what callers expect. Document the behavior. Current callers only call peel_ref() from within a for_each_ref-style iteration and only for the current ref; therefore, the buggy code path was never reached.

2013-03-09reflog: add for_each_reflog_ent_reverse() APIJunio C Hamano
"git checkout -" is a short-hand for "git checkout @{-1}" and the "@{nth}" notation for a negative number is to find nth previous checkout in the reflog of the HEAD to determine the name of the branch the user was on. We would want to find the nth most recent reflog entry that matches "checkout: moving from X to Y" for this. Unfortunately, reflog is implemented as an append-only file, and the API to iterate over its entries, for_each_reflog_ent(), reads the file in order, giving the entries from the oldest to newer. For the purpose of finding nth most recent one, this API forces us to record the last n entries in a rotating buffer and give the result out only after we read everything. To optimize for a common case of finding the nth most recent one for a small value of n, we also have a side API for_each_recent_reflog_ent() that starts reading near the end of the file, but it still has to read the entries in the "wrong" order. The implementation of understanding @{-1} uses this interface. This all becomes unnecessary if we add an API to let us iterate over reflog entries in the reverse order, from the newest to older.

2013-02-08upload/receive-pack: allow hiding ref hierarchiesJunio C Hamano
A repository may have refs that are only used for its internal bookkeeping purposes that should not be exposed to the others that come over the network. Teach upload-pack to omit some refs from its initial advertisement by paying attention to the uploadpack.hiderefs multi-valued configuration variable. Do the same to receive-pack via the receive.hiderefs variable. As a convenient short-hand, allow using transfer.hiderefs to set the value to both of these variables. Any ref that is under the hierarchies listed on the value of these variable is excluded from responses to requests made by "ls-remote", "fetch", etc. (for upload-pack) and "push" (for receive-pack). Because these hidden refs do not count as OUR_REF, an attempt to fetch objects at the tip of them will be rejected, and because these refs do not get advertised, "git push :" will not see local branches that have the same name as them as "matching" ones to be sent. An attempt to update/delete these hidden refs with an explicit refspec, e.g. "git push origin :refs/hidden/22", is rejected. This is not a new restriction. To the pusher, it would appear that there is no such ref, so its push request will conclude with "Now that I sent you all the data, it is time for you to update the refs. I saw that the ref did not exist when I started pushing, and I want the result to point at this commit". The receiving end will apply the compare-and-swap rule to this request and rejects the push with "Well, your update request conflicts with somebody else; I see there is such a ref.", which is the right thing to do. Otherwise a push to a hidden ref will always be "the last one wins", which is not a good default. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-04-11refs: store references hierarchicallyMichael Haggerty
Store references hierarchically in a tree that matches the pseudo-directory structure of the reference names. Add a new kind of ref_entry (with flag REF_DIR) to represent a whole subdirectory of references. Sort ref_dirs one subdirectory at a time. NOTE: the dirs can now be sorted as a side-effect of other function calls. Therefore, it would be problematic to do something from a each_ref_fn callback that could provoke the sorting of a directory that is currently being iterated over (i.e., the directory containing the entry that is being processed or any of its parents). This is a bit far-fetched, because a directory is always sorted just before being iterated over. Therefore, read-only accesses cannot trigger the sorting of a directory whose iteration has already started. But if a callback function would add a reference to a parent directory of the reference in the iteration, then try to resolve a reference under that directory, a re-sort could be triggered and cause the iteration to work incorrectly. Nevertheless...add a comment in refs.h warning against modifications during iteration. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>

* js/ref-namespaces: ref namespaces: tests ref namespaces: documentation ref namespaces: Support remote repositories via upload-pack and receive-pack ref namespaces: infrastructure Fix prefix handling in ref iteration functions
2011-07-06ref namespaces: infrastructureJosh Triplett
Add support for dividing the refs of a single repository into multiple namespaces, each of which can have its own branches, tags, and HEAD. Git can expose each namespace as an independent repository to pull from and push to, while sharing the object store, and exposing all the refs to operations such as git-gc. Storing multiple repositories as namespaces of a single repository avoids storing duplicate copies of the same objects, such as when storing multiple branches of the same source. The alternates mechanism provides similar support for avoiding duplicates, but alternates do not prevent duplication between new objects added to the repositories without ongoing maintenance, while namespaces do. To specify a namespace, set the GIT_NAMESPACE environment variable to the namespace. For each ref namespace, git stores the corresponding refs in a directory under refs/namespaces/. For example, GIT_NAMESPACE=foo will store refs under refs/namespaces/foo/. You can also specify namespaces via the --namespace option to git. Note that namespaces which include a / will expand to a hierarchy of namespaces; for example, GIT_NAMESPACE=foo/bar will store refs under refs/namespaces/foo/refs/namespaces/bar/. This makes paths in GIT_NAMESPACE behave hierarchically, so that cloning with GIT_NAMESPACE=foo/bar produces the same result as cloning with GIT_NAMESPACE=foo and cloning from that repo with GIT_NAMESPACE=bar. It also avoids ambiguity with strange namespace paths such as foo/refs/heads/, which could otherwise generate directory/file conflicts within the refs directory. Add the infrastructure for ref namespaces: handle the GIT_NAMESPACE environment variable and --namespace option, and support iterating over refs in a namespace.

2011-06-06checkout -b <name>: correctly detect existing branchJunio C Hamano
When create a new branch, we fed "refs/heads/<proposed name>" as a string to get_sha1() and expected it to fail when a branch already exists. The right way to check if a ref exists is to check with resolve_ref(). A naïve solution that might appear attractive but does not work is to forbid slashes in get_describe_name() but that will not work. A describe name is is in the form of "ANYTHING-g<short sha1>", and that ANYTHING part comes from a original tag name used in the repository the user ran the describe command. A sick user could have a confusing hierarchical tag whose name is "refs/heads/foobar" (stored as refs/tags/refs/heads/foobar") to generate a describe name "refs/heads/foobar-6-g02ac983", and we should be able to use that name to refer to the object whose name is 02ac983.
