2009-02-27builtin-remote: make get_remote_ref_states() always populate states.trackedLibravatar Jay Soffian1-17/+16
When not querying the remote, show() was having to populate states.tracked itself. It makes more sense for get_remote_ref_states() to do this consistently. Since show() is the only caller of get_remote_ref_states() with query=0, this change does not affect other callers.

2009-02-27builtin-remote: rename variables and eliminate redundant function callLibravatar Jay Soffian1-12/+12
- The variable name "remote" is used as both a "char *" and as a "struct remote *"; this is confusing, so rename the former to remote_name. - Consistently refer to the refs returned by transport_get_remote_refs() as remote_refs. - There is no need to call "sort_string_list(&branch_list)" as branch_list is populated via string_list_insert(), which maintains its order.

2009-02-27builtin-remote: refactor duplicated cleanup codeLibravatar Jay Soffian1-8/+9
This patch moves identical lines of code into a cleanup function. The function has two callers and is about to gain a third. Also removed a bogus NEEDSWORK comment per Daniel Barkalow: Actually, the comment is wrong; "remote" comes from remote_get(), which returns things from a cache in remote.c; there could be a remote_put() to let the code know that the caller is done with the object, but it wouldn't presently do anything.

2009-02-27remote: make match_refs() not short-circuitLibravatar Jay Soffian1-2/+4
match_refs() returns non-zero if there is an error in match_explicit_refs(), without handling any remaining pattern ref specs. Its existing callers exit upon receiving non-zero, so a partial result is of no consequence to them; however a new caller, builtin-remote, is interested in the complete result even if there are errors in match_explicit_refs().

2009-02-27remote: make match_refs() copy src ref before assigning to peer_refLibravatar Jay Soffian1-2/+5
In some instances, match_refs() sets the peer_ref field of refs in the dst list such that it points to a ref in the src list. This prevents callers from freeing both the src and dst lists, as doing so would cause a double-free since free_refs() frees the peer_ref. As well, the following configuration causes two refs in the dst list to have the same peer_ref, which can also lead to a double-free: push = refs/heads/master:refs/heads/backup push = refs/heads/master:refs/heads/master Existing callers of match_heads() call it only once and then terminate, w/o ever bothering to free the src or dst lists, so this is not currently a problem. This patch modifies match_refs() to first copy any refs it plucks from the src list before assigning them as a peer_ref. This allows builtin-remote, a future caller, to free the src and dst lists.

2009-02-27remote: let guess_remote_head() optionally return all matchesLibravatar Jay Soffian3-17/+28
Determining HEAD is ambiguous since it is done by comparing SHA1s. In the case of multiple matches we return refs/heads/master if it matches, else we return the first match we encounter. builtin-remote needs all matches returned to it, so add a flag for it to request such. To be simple and consistent, the return value is now a copy (including peer_ref) of the matching refs. Originally contributed by Jeff King along with the prior commit as a single patch.

2009-02-27remote: make copy_ref() perform a deep copyLibravatar Jay Soffian1-5/+13
To ensure that copied refs can always be freed w/o causing a double-free, make copy_ref() perform a deep copy. Also have copy_ref() return NULL if asked to copy NULL to simplify things for the caller. Background: currently copy_ref() performs a shallow copy. This is fine for current callers who never free the result and/or only copy refs which contain NULL pointers. But copy_ref() is about to gain a new caller (guess_remote_head()) which copies refs where peer_ref is not NULL and the caller of guess_remote_head() will want to free the result.

2009-02-26remote: simplify guess_remote_head()Libravatar Jay Soffian3-32/+16
This function had complications which made it hard to extend. - It used to do two things: find the HEAD ref, and then find a matching ref, optionally returning the former via assignment to a passed-in pointer. Since finding HEAD is a one-liner, just have a caller do it themselves and pass it as an argument. - It used to manually search through the ref list for refs/heads/master; this can be a one-line call to find_ref_by_name.

2009-02-26move duplicated ref_newer() to remote.cLibravatar Jay Soffian4-99/+50
ref_newer() appears to have been copied from builtin-send-pack.c to http-push.c via cut and paste. This patch moves the function and its helper unmark_and_free() to remote.c. There was a slight difference between the two implementations, one used TMP_MARK for the mark, the other used 1. Per Jeff King, I went with TMP_MARK as more correct.

The two copies of one_local_ref() were not identical. I used the more recent version from builtin-send-pack.c after confirming with Jeff King that it was an oversight that commit 30affa1e did not update both copies.

2009-02-26refactor find_ref_by_name() to accept const listLibravatar Jeff King2-3/+3
Since it doesn't actually touch its argument, this makes sense. However, we still want to return a non-const version (which requires a cast) so that this: struct ref *a, *b; a = find_ref_by_name(b); works. Unfortunately, you can also silently strip the const from a variable: struct ref *a; const struct ref *b; a = find_ref_by_name(b); This is a classic C const problem because there is no way to say "return the type with the same constness that was passed to us"; we provide the same semantics as standard library functions like strchr.

2009-02-26add basic http clone/fetch testsLibravatar Jeff King3-0/+48
This was mostly being tested implicitly by the "http push" tests. But making a separate test script means that: - we will run fetch tests even when http pushing support is not built - when there are failures on fetching, they are easier to see and isolate, as they are not in the middle of push tests This script defaults to running the webserver on port 5550, and puts the original t5540 on port 5540, so that the two can be run simultaneously without conflict (but both still respect an externally set LIB_HTTPD_PORT).

There are some redirects and some error checking that need to be done by the caller; let's move both into the start_httpd function so that all callers don't have to repeat them (there is only one caller now, but another will follow in this series). This doesn't violate any assumptions that aren't already being made by lib-httpd, which is happy to say "skipping" and call test_done for a number of other cases.

* jc/maint-1.6.0-pack-directory: Make sure objects/pack exists before creating a new pack
2009-02-25Make sure objects/pack exists before creating a new packLibravatar Junio C Hamano7-27/+72
In a repository created with git older than f49fb35 (git-init-db: create "pack" subdirectory under objects, 2005-06-27), objects/pack/ directory is not created upon initialization. It was Ok because subdirectories are created as needed inside directories init-db creates, and back then, packfiles were recent invention. After the said commit, new codepaths started relying on the presense of objects/pack/ directory in the repository. This was exacerbated with 8b4eb6b (Do not perform cross-directory renames when creating packs, 2008-09-22) that moved the location temporary pack files are created from objects/ directory to objects/pack/ directory, because moving temporary to the final location was done carefully with lazy leading directory creation. Many packfile related operations in such an old repository can fail mysteriously because of this. This commit introduces two helper functions to make things work better. - odb_mkstemp() is a specialized version of mkstemp() to refactor the code and teach it to create leading directories as needed; - odb_pack_keep() refactors the code to create a ".keep" file while create leading directories as needed.

2009-02-25Allow HTTP tests to run on DarwinLibravatar Jay Soffian2-5/+23
This patch allows the HTTP tests to run on OS X 10.5. It is not sufficient to be able to pass in LIB_HTTPD_PATH and LIB_HTTPD_MODULE_PATH alone, as the apache.conf also needs a couple tweaks. These changes are put into an <IfDefine> to keep them Darwin specific, but this means lib-httpd.sh needs to be modified to pass -DDarwin to apache when running on Darwin. As long as we're making this change to lib-httpd.sh, we may as well set LIB_HTTPD_PATH and LIB_HTTPD_MODULE_PATH to appropriate default values for the platform. Note that we now pass HTTPD_PARA to apache at shutdown as well. Otherwise apache will emit a harmless, but noisy warning that LogFormat is an unknown directive.

2009-02-19gitweb: Hyperlink multiple git hashes on the same commit message lineLibravatar Marcel M. Cary1-7/+5
The current implementation only hyperlinks the first hash on a given line of the commit message. It seems sensible to highlight all of them if there are multiple, and it seems plausible that there would be multiple even with a tidy line length limit, because they can be abbreviated as short as 8 characters. Benchmark: I wanted to make sure that using the 'e' switch to the Perl regex wasn't going to kill performance, since this is called once per commit message line displayed. In all three A/B scenarios I tried, the A and B yielded the same results within 2%, where A is the version of code before this patch and B is the version after. 1: View a commit message containing the last 1000 commit hashes 2: View a commit message containing 1000 lines of 40 dots to avoid hyperlinking at the same message length 3: View a short merge commit message with a few lines of text and no hashes All were run in CGI mode on my sub-production hardware on a recent clone of git.git. Numbers are the average of 10 reqests per second with the first request discarded, since I expect this change to affect primarily CPU usage. Measured with ApacheBench. Note that the web page rendered was the same; while the new code supports multiple hashes per line, there was at most one per line. The primary purpose of scenarios 2 and 3 were to verify that the addition of 1000 commit messages had an impact on how much of the time was spent rendering commit messages. They were all within 2% of 0.80 requests per second (much faster). So I think the patch has no noticeable effect on performance. Signed-off-by: Marcel M.
