"git log frotz" can DWIM to "refs/remotes/frotz/HEAD", but in the remote access context, "git fetch frotz" to fetch what the other side happened to have fetched from what it calls 'frotz' (which may not have any relation to what we consider is 'frotz') the last time would not make much sense, so the fetch rules table did not include "refs/remotes/%.*s/HEAD". When the user really wants to, "git fetch $there remotes/frotz/HEAD" would let her do so anyway, so this is not about safety or security; it merely is about confusion avoidance and discouraging meaningless usage. Specifically, it is _not_ about ambiguity avoidance. A name that would become ambiguous if we use the same rules table for both fetch and local rev-parse would be ambiguous locally at the remote side. So for the same reason as we added rule to allow "git fetch $there v1.0" instead of "git fetch $there tags/v1.0" in the previous commit, here is a bit longer rope for the users, which incidentally simplifies our code.

2c5c66be (Merge branch 'jp/get-ref-dir-unsorted', 2011-10-10) merged a topic that forked from the mainline before a new helper function get_packed_refs() refactored code to read packed-refs file. The merge made the call to the helper function with an incorrect argument. The parameter to the function has to be a path to the submodule. Fix the mismerge.

The bsearch() implementation on IRIX 6.5 segfaults if it is passed NULL for the base array argument even if number-of-elements is zero. So, let's work around it by detecting an empty array and aborting early. This is a useful optimization in its own right anyway, since we avoid a useless allocation and initialization of the ref_entry when the ref array is empty.

The variable "refs" is allocated on the stack but is not initialized. It is passed to read_packed_refs(), and its struct members may eventually be passed to add_ref() and ALLOC_GROW(). Since the structure has not been initialized, its members may contain random non-zero values. So let's initialize it. The call sequence looks something like this: resolve_gitlink_packed_ref(...) { struct cached_refs refs; ... read_packed_refs(f, &refs); ... } read_packed_refs(FILE*, struct cached_refs *cached_refs) { ... add_ref(name, sha1, flag, &cached_refs->packed, &last); ... } add_ref(..., struct ref_array *refs, struct ref_entry **) { ... ALLOC_GROW(refs->refs, refs->nr + 1, refs->alloc); } Signed-off-by: NBrandon Casey <casey@nrlssc.navy.mil> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

In add_ref(), verify that the refname is formatted correctly before adding it to the ref_list. Here we have to allow refname components that start with ".", since (for example) the remote protocol uses synthetic reference name ".have". So add a new REFNAME_DOT_COMPONENT flag that can be passed to check_refname_format() to allow leading dots.

Since much of the infrastructure does not work correctly with unnormalized refnames, change check_refname_format() to reject them. Similarly, change "git check-ref-format" to reject unnormalized refnames by default. But add an option --normalize, which causes "git check-ref-format" to normalize the refname before checking its format, and print the normalized refname. This is exactly the behavior of the old --print option, which is retained but deprecated. Signed-off-by: NMichael Haggerty <mhagger@alum.mit.edu> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

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.

Previously most bad characters were indicated by returning 1, but "*" was special-cased to return 2 instead of 1. One caller examined the return value to see whether the special case occurred. But it is easier (to document and understand) for bad_ref_char() simply to return a boolean value, treating "*" like any other bad character. Special-case the handling of "*" (which only occurs in very specific circumstances) at the caller. The resulting calling code thereby also becomes more transparent.

Currently we linearly search through lists of refs when we need to find a specific ref. This can be very slow if we need to lookup a large number of refs. By changing to a binary search we can make this faster. In order to be able to use a binary search we need to change from using linked lists to arrays, which we can manage using ALLOC_GROW. We can now also use the standard library qsort function to sort the refs arrays. Signed-off-by: NJulian Phillips <julian@quantumfyre.co.uk> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

When a push specifies deletion of non-existent refs, the post post-receive and post-update hooks receive them as input/arguments. For instance, for the following push, where refs/heads/nonexistent is a ref which does not exist on the remote side: git push origin :refs/heads/nonexistent the post-receive hook receives from standard input: <null-sha1> SP <null-sha1> SP refs/heads/nonexistent and the post-update hook receives as arguments: refs/heads/nonexistent which does not make sense since it is a no-op. Teach receive-pack not to pass non-existent refs to the post-receive and post-update hooks. If the push only attempts to delete non-existent refs, these hooks are not even called. The update and pre-receive hooks are still notified about attempted deletion of non-existent refs to give them a chance to inspect the situation and act on it.

get_ref_dir is called recursively for subdirectories, which means that we were calling sort_ref_list for each directory of refs instead of once for all the refs. This is a massive wast of processing, so now just call sort_ref_list on the result of the top-level get_ref_dir, so that the sort is only done once. In the common case of only a few different directories of refs the difference isn't very noticable, but it becomes very noticeable when you have a large number of direcotries containing refs (e.g. as created by Gerrit).

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.

The do_for_each_ref iteration function accepts a prefix and a trim, and checks for the prefix on each ref before passing in that ref; it also supports trimming off part of the ref before passing it. However, do_for_each_ref used trim as the length of the prefix to check, ignoring the actual length of the prefix. Switch to using prefixcmp, checking the entire length of the prefix string, to properly support a trim value different than the length of the prefix. Several callers passed a prefix of "refs/" to filter out everything outside of refs/, but a trim of 0 to avoid trimming off the "refs/"; the trim of 0 meant that the filter of "refs/" no longer applied. Change these callers to pass an empty prefix instead, to avoid changing the existing behavior. Various callers count on this lack of filtering, such as receive-pack which uses add_extra_ref to add alternates as refs named ".have"; adding filtering would break that, causing t5501-fetch-push-alternates.sh to fail. That lack of filtering doesn't currently have any other effect, since the loose ref functions can never supply refs outside of "refs/", and packed-refs will not normally include such refs unless manually edited.

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-g02ac9837", and we should be able to use that name to refer to the object whose name is 02ac9837.
