* write_ref_sha1(): only invalidate the loose ref cacheMichael Haggerty2011-10-16
| | | | | | | | | | Since write_ref_sha1() can only write loose refs and cannot write symbolic refs, there is no need for it to invalidate the packed ref cache.

* invalidate_ref_cache(): expose this function in the refs APIMichael Haggerty2011-10-16
| | | | | | | | | | Make invalidate_ref_cache() an official part of the refs API. It is currently a fact of life that code outside of refs.c mucks about with references. This change gives such code a way of informing the refs module that it should no longer trust its cache.

* invalidate_ref_cache(): rename function from invalidate_cached_refs()Michael Haggerty2011-10-16
| | | | | | | | | | | | | | It is the cache that is being invalidated, not the references, and the new name makes this unambiguous. Rename other items analogously: * struct cached_refs -> struct ref_cache * cached_refs (the variable) -> ref_cache * clear_cached_refs() -> clear_ref_cache() * create_cached_refs() -> create_ref_cache() * get_cached_refs() -> get_ref_cache() Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Most of the time we are at the base level of the repository, so base is "" and baselen == 0, which means we will always test true. Break out this one tiny case so we can short circuit the strncmp() call. Test cases are as follows. packages.git is the Arch Linux git-svn clone of the packages repository which has the characteristics above. Commands: [1] packages.git, /usr/bin/time git log >/dev/null [2] packages.git, /usr/bin/time git log -- autogen/trunk pacman/trunk wget/trunk >/dev/null [3] linux.git, /usr/bin/time git log >/dev/null [4] linux.git, /usr/bin/time git log -- drivers/ata drivers/uio tools >/dev/null Results: before after %faster [1] 2.56 2.55 0.4% [2] 51.82 48.66 6.5% [3] 5.58 5.61 -0.5% [4] 1.55 1.51 0.2% The takeaway here is this doesn't matter in many operations, but it does for a certain style of repository and operation where it nets a 6.5% measured improvement. The other changes are likely not significant by reasonable statistics methods. Note: the measured improvement when originally submitted was ~11% (43 to 38 secs) for operation [2].

This is used to signal to gitweb that the browser can actually do javascript when these links are used. There are two problems with the existing code: 1. URIs with fragment and 'js' query parameter, like e.g. ...foo?js=0#l199 were not recognized as having 'js' query parameter already. 2. The 'js' query parameter, in the form of either '?js=1' or ';js=1' was appended at the end of URI, even if it included a fragment (had a hash part). This lead to the incorrect links like this ...foo#l199?js=1 instead of adding query parameter as last part of query, but before the fragment part, i.e. ...foo?js=1#l199 Signed-off-by: Peter Stuge <peter@stuge.se> Acked-by: Jakub Narebski <jnareb@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

This used to work before 9037026 (unpack-trees: fix sparse checkout's "unable to match directories") because back then, the list of paths is used to match sparse patterns, so with the patterns * !subdir/ subdir/ always matches any path that start with subdir/ and "*" has no chance to get tested. The result is subdir is excluded. After the said commit, a tree structure is dynamically created and sparse pattern matching now follows closely how read_directory() applies .gitignore. This solves one problem, but reveals another one. With this new strategy, "!subdir/" rule will be only tested once when "subdir" directory is examined. Entries inside subdir, when examined, will match "*" and are (correctly) re-added again because any rules without a slash will match at every directory level. In the end, "*" can revert every negation rules. In order to correctly exclude subdir, we must use /* !subdir to limit "match all" rule at top level only. "*" rule has no actual use in sparse checkout and can be confusing to users. While we can automatically turn "*" to "/*", this violates .gitignore definition. Instead, discourage "*" in favor of "/*" (in the second example). Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

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 **) { ...

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: Julian Phillips <julian@quantumfyre.co.uk> Signed-off-by: Junio C Hamano <gitster@pobox.com>

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).

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.

| * | | | | | Change bad_ref_char() to return a boolean valueMichael Haggerty2011-10-05

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.

(Actually, one big reason to add the new options is to make it easy to test check_ref_format(), though the options should also be useful to other scripts.) Interpret the result of check_ref_format() based on which types of refnames are allowed. However, because check_ref_format() can only return a single value, one test case is still broken. Specifically, the case "git check-ref-format --onelevel '*'" incorrectly succeeds because check_ref_format() returns CHECK_REF_FORMAT_ONELEVEL for this refname even though the refname is also CHECK_REF_FORMAT_WILDCARD. The type of check that leads to this failure is used elsewhere in "real" code and could lead to bugs; it will be fixed over the next few commits.

| * | | | | | get_sha1_hex(): do not read past a NUL characterMichael Haggerty2011-10-05

Although the function correctly returned -1 in these cases, the extra memory access might have been to uninitialized (or even, conceivably, unallocated) memory. Add a check to avoid reading past the end of a string. This problem was discovered by Thomas Rast <trast@student.ethz.ch> using valgrind.
