* dir.c: use a single struct exclude_list per source of excludesAdam Spiers2013-01-066-39/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously each exclude_list could potentially contain patterns from multiple sources. For example dir->exclude_list[EXC_FILE] would typically contain patterns from .git/info/exclude and core.excludesfile, and dir->exclude_list[EXC_DIRS] could contain patterns from multiple per-directory .gitignore files during directory traversal (i.e. when dir->exclude_stack was more than one item deep). We split these composite exclude_lists up into three groups of exclude_lists (EXC_CMDL / EXC_DIRS / EXC_FILE as before), so that each exclude_list now contains patterns from a single source. This will allow us to cleanly track the origin of each pattern simply by adding a src field to struct exclude_list, rather than to struct exclude, which would make memory management of the source string tricky in the EXC_DIRS case where its contents are dynamically generated. Similarly, by moving the filebuf member from struct exclude_stack to struct exclude_list, it allows us to track and subsequently free memory buffers allocated during the parsing of all exclude files, rather than only tracking buffers allocated for files in the EXC_DIRS group.

* dir.c: rename free_excludes() to clear_exclude_list()Adam Spiers2012-12-283-3/+7
| | | | | | | | | | | | It is clearer to use a 'clear_' prefix for functions which empty and deallocate the contents of a data structure without freeing the structure itself, and a 'free_' prefix for functions which also free the structure itself. http://article.gmane.org/gmane.comp.version-control.git/206128 Signed-off-by: Adam Spiers <git@adamspiers.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* dir.c: refactor is_path_excluded()Adam Spiers2012-12-282-9/+41
| | | | | | | | | | | | | | | | In a similar way to the previous commit, this extracts a new helper function last_exclude_matching_path() which return the last exclude_list element which matched, or NULL if no match was found. is_path_excluded() becomes a wrapper around this, and just returns 0 or 1 depending on whether any matching exclude_list element was found. This allows callers to find out _why_ a given path was excluded, rather than just whether it was or not, paving the way for a new git sub-command which allows users to test their exclude lists from the command line.

* dir.c: refactor is_excluded_from_list()Adam Spiers2012-12-281-9/+28
| | | | | | | | | | | | | | | | | | | The excluded function uses a new helper function called last_exclude_matching_from_list() to perform the inner loop over all of the exclude patterns. The helper just tells us whether the path is included, excluded, or undecided. However, it may be useful to know _which_ pattern was triggered. So let's pass out the entire exclude match, which contains the status information we were already passing out. Further patches can make use of this.

* attr: more matching optimizations from .gitignoreNguyễn Thái Ngọc Duy2012-10-155-32/+64
| | | | | | | | | | | | | | | | | | | | | | | .gitattributes and .gitignore share the same pattern syntax but has separate matching implementation. Over the years, ignore's implementation accumulates more optimizations while attr's stays the same. This patch reuses the core matching functions that are also used by excluded_from_list. excluded_from_list and path_matches can't be merged due to differences in exclude and attr, for example: * "!pattern" syntax is forbidden in .gitattributes. As an attribute can be unset (i.e. set to a special value "false") or made back to unspecified (i.e. not even set to "false"), "!pattern attr" is unclear which one it means. * we support attaching attributes to directories, but git-core internally does not currently make use of attributes on directories.

| | | | | | | | | | | | | When "namelen" becomes zero at this stage, we have matched the fixed part, but whether it actually matches the pattern still depends on the pattern in "exclude". As demonstrated in t3001, path "three/a.3" exists and it matches the "three/a.3" part in pattern "three/a.3[abc]", but that does not mean a true match.

This had the effect of silencing diff output from the log (which was not intended, but happened to work and people started to use it). But it also had other odd side effects at the diff level (for example, it would suppress the second commit in "git show A B"). To fix this, commit 1c40c36 converted log to parse-options and handled the "quiet" option separately, not passing it on to the diff code. However, it simply ignored the option, which was a regression for people using it as a synonym for "-s". Commit 01771a8 then fixed that by interpreting the option to add DIFF_FORMAT_NO_OUTPUT to the list of output formats. However, that commit did not fix it in all cases. It sets the flag after setup_revisions is called. Naively, this makes sense because you would expect the setup_revisions parser to overwrite our output format flag if "-p" or another output format flag is seen. However, that is not how the NO_OUTPUT flag works. We actually store it in the bit-field as just another format. At the end of setup_revisions, we call diff_setup_done, which post-processes the bitfield and clears any other formats if we have set NO_OUTPUT. By setting the flag after setup_revisions is done, diff_setup_done does not have a chance to make this tweak, and we end up with other format options still set. As a result, the flag would have no effect in "git log -p --quiet" or "git show --quiet". Fix it by setting the format flag before the call to setup_revisions.

This obviously does not work well when running under -p0 where we do not want to skip any, but still want to skip SP/HT that separates the pathnames of preimage and postimage and want to reject absolute pathnames. Stop using "stop_at_slash()", and instead introduce a new helper "skip_tree_prefix()" with similar logic but works correctly even for the -p0 case. This is an ancient bug, but has been masked for a long time because most of the patches are text and have other clues to tell us the name of the preimage and the postimage. Noticed by Colin McCabe.

POST requests, however, do not go through any central point. Moreover, it is difficult to retry in the general case; we cannot assume the request body fits in memory or is even seekable, and we don't know how much of it was consumed during the attempt. Most of the time, this is not a big deal; for both fetching and pushing, we make a GET request before doing any POSTs, so typically we figure out the credentials during the first request, then reuse them during the POST. However, some servers may allow a client to get the list of refs from receive-pack without authentication, and then require authentication when the client actually tries to POST the pack. This is not ideal, as the client may do a non-trivial amount of work to generate the pack (e.g., delta-compressing objects). However, for a long time it has been the recommended example configuration in git-http-backend(1) for setting up a repository with anonymous fetch and authenticated push. This setup has always been broken without putting a username into the URL. Prior to commit 986bbc0, it did work with a username in the URL, because git would prompt for credentials before making any requests at all. However, post-986bbc0, it is totally broken. Since it has been advertised in the manpage for some time, we should make sure it works. Unfortunately, it is not as easy as simply calling post_rpc again when it fails, due to the input issue mentioned above. However, we can still make this specific case work by retrying in two specific instances: 1. If the request is large (bigger than LARGE_PACKET_MAX), we will first send a probe request with a single flush packet. Since this request is static, we can freely retry it. 2. If the request is small and we are not using gzip, then we have the whole thing in-core, and we can freely retry. That means we will not retry in some instances, including: 1. If we are using gzip. However, we only do so when calling git-upload-pack, so it does not apply to pushes. 2. If we have a large request, the probe succeeds, but then the real POST wants authentication. This is an extremely unlikely configuration and not worth worrying about. While it might be nice to cover those instances, doing so would be significantly more complex for very little real-world gain. In the long run, we will be much better off when curl learns to internally handle authentication as a callback, and we can cleanly handle all cases that way.

In particular, it handles prompting for missing credentials as well as approving and rejecting valid or invalid credentials. Unfortunately, it only handles GET requests. Making it handle POSTs would be quite complex, so let's pull result handling code into its own function so that it can be reused from the POST code paths.

| * | | | | | | | t: test http access to "half-auth" repositoriesJeff King2012-08-273-0/+28

While there are multiple ways to do this, the technique advertised in the git-http-backend manpage is to block access to locations matching "/git-receive-pack$". Let's emulate that advice in our test setup, which makes it clear that this advice does not actually work. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

In theory, it should work exactly as it does for dumb http (which we do test). It does indeed work for these simple tests, but this patch lays the groundwork for more complex tests in future patches.

Part of the infrastructure to do this is recognizing that auth/smart is indeed a smart-http repo. The current apache config recognizes only "^/smart/*" as smart-http. Let's instead treat anything with /smart/ in the URL as smart-http. This is obviously a stupid thing to do for a real production site, but for our test suite we know that our repositories will not have this magic string in the name. Note that we will route /foo/smart/bar.git directly to git-http-backend/bar.git; in other words, everything before the "/smart/" is irrelevant to finding the repo on disk (but may impact apache config, for example by triggering auth checks).
