* Merge branch 'jl/pack-transfer-avoid-double-close'Junio C Hamano2013-10-302-0/+8
|\ | | | | | | | | | | | | | | | | The codepath that send_pack() calls pack_objects() mistakenly closed the same file descriptor twice, leading to potentially closing a wrong file descriptor that was opened in the meantime. * jl/pack-transfer-avoid-double-close: Clear fd after closing to avoid double-close error
| * Clear fd after closing to avoid double-close errorjl/pack-transfer-avoid-double-closeJens Lindstrom2013-10-232-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In send_pack(), clear the fd passed to pack_objects() by setting it to -1, since pack_objects() closes the fd (via a call to run_command()). Likewise, in get_pack(), clear the fd passed to run_command(). Not doing so risks having git_transport_push(), caller of send_pack(), closing the fd again, possibly incorrectly closing some other open file; or similarly with fetch_refs_from_pack(), indirect caller of get_pack().

|\ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | All callers to parse_pathspec() must choose between getting no pathspec or one path that is limited to the current directory when there is no paths given on the command line, but there were two callers that violated this rule, triggering a BUG(). * nd/magic-pathspec: Fix calling parse_pathspec with no paths nor PATHSPEC_PREFER_* flags
| * | Fix calling parse_pathspec with no paths nor PATHSPEC_PREFER_* flagsNguyễn Thái Ngọc Duy2013-10-223-2/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When parse_pathspec() is called with no paths, the behavior could be either return no paths, or return one path that is cwd. Some commands do the former, some the latter. parse_pathspec() itself does not make either the default and requires the caller to specify either flag if it may run into this situation. I've grep'd through all parse_pathspec() call sites. Some pass neither, but those are guaranteed never pass empty path to parse_pathspec(). There are two call sites that may pass empty path and are fixed with this patch.

A user running "ls .git/" and finding this file may incorrectly guess that a "git gc" is currently running. * Leaving this file means that a "git gc" in an already gc-ed repo is no-longer a no-op. A user running "git gc" in a set of repositories, and then synchronizing this set (e.g. rsync -av, unison, ...) will see all the gc.pid files as changed, which creates useless noise. This patch unlinks the file after the garbage collection is done, so that gc.pid is actually present only during execution. Future versions of Git may want to use the information left in the gc.pid file (e.g. for policies like "don't attempt to run a gc if one has already been ran less than X hours ago"). If so, this patch can safely be reverted. For now, let's not bother the users.

This test is silently broken for the following reasons: - The test crafts a special index by feeding a large number of index entries with null shas to 'git update-index --index-info'. It was OK back then when this test was introduced in commit 0693f9ddad (Make sure lockfiles are unlocked when dying on SIGPIPE, 2008-12-18), but since commit 4337b5856f (do not write null sha1s to on-disk index, 2012-07-28) null shas are not allowed in the on-disk index causing 'git update-index' to error out. - The barfing 'git update-index --index-info' should fail the test, but it remains unnoticed because of the severely broken && chain: the test's result depends solely on whether there is a stale lock file left behind, but after 'git update-index' errors out 'git rm' won't be executed at all. To fix this test feed only non-null shas to 'git update-index' and restore the && chain (partly by adding a missing && and by using the test_when_finished helper instead of manual cleanup).

We usually refrain from making this kind of a tree-wide change in order to avoid unnecessary conflicts with other "real work" patches, but in this case, the end result does not have a potentially cumbersome tree-wide impact, while this is a tree-wide cleanup. Fixes to compat/regex/regcomp.c and xdiff/xemit.c are to replace a HT immediately after && with a SP. This is based on Felipe's patch to bultin/symbolic-ref.c; I did all the finding out what other files in the whole tree need to be fixed and did the fix and also the log message while reviewing that single liner, so any screw-ups in this version are mine.

However, it neglected to update the (single) call site. Since this call was passing '0' to that argument, it was (correctly) being interpreted as a null pointer. Change to argument to NULL.

This commit wires that option into the info/refs request, meaning that a redirect from http://example.com/foo.git/info/refs to https://example.com/bar.git/info/refs will behave as if "https://example.com/bar.git" had been provided to git in the first place. The tests bear some explanation. We introduce two new hierearchies into the httpd test config: 1. Requests to /smart-redir-limited will work only for the initial info/refs request, but not any subsequent requests. As a result, we can confirm whether the client is re-rooting its requests after the initial contact, since otherwise it will fail (it will ask for "repo.git/git-upload-pack", which is not redirected). 2. Requests to smart-redir-auth will redirect, and require auth after the redirection. Since we are using the redirected base for further requests, we also update the credential struct, in order not to mislead the user (or credential helpers) about which credential is needed. We can therefore check the GIT_ASKPASS prompts to make sure we are prompting for the new location. Because we have neither multiple servers nor https support in our test setup, we can only redirect between paths, meaning we need to turn on credential.useHttpPath to see the difference.

This makes it harder to later manipulate the URL, as we have forgotten the length (and the allocation semantics are not as clear). Let's instead keep the strbuf around. As a bonus, this eliminates a confusing double-use of the "buf" strbuf in main(). Prior to this, it was used both for constructing the url, and for reading commands from stdin. The downside is that we have to update each call site to refer to "url.buf" rather than just "url" when they want the C string.

It would be nice to remember this redirect and short-cut further requests for two reasons: 1. It's more efficient. Otherwise we spend an extra http round-trip to the server for each subsequent request, just to get redirected. 2. If we end up with an http 401 and are going to ask for credentials, it is to feed them to the redirect target. If the redirect is an http->https upgrade, this means our credentials may be provided on the http leg, just to end up redirected to https. And if the redirect crosses server boundaries, then curl will drop the credentials entirely as it follows the redirect. However, it, it is not enough to simply record the effective URL we saw and use that for subsequent requests. We were originally fed a "base" url like: http://example.com/foo.git and we want to figure out what the new base is, even though the URLs we see may be: original: http://example.com/foo.git/info/refs effective: http://example.com/bar.git/info/refs Subsequent requests will not be for "info/refs", but for other paths relative to the base. We must ask the caller to pass in the original base, and we must pass the redirected base back to the caller (so that it can generate more URLs from it). Furthermore, we need to feed the new base to the credential code, so that requests to credential helpers (or to the user) match the URL we will be requesting. This patch teaches http_request_reauth to do this munging. Since it is the caller who cares about making more URLs, it seems at first glance that callers could simply check effective_url themselves and handle it. However, since we need to update the credential struct before the second re-auth request, we have to do it inside http_request_reauth.

When we see an HTTP 401, we do one of two things: 1. If we already had a filled-in credential, we mark it as rejected, and then return HTTP_NOAUTH to indicate to the caller that we failed. 2. If we didn't, then we ask for a new credential and tell the caller HTTP_REAUTH to indicate that they may want to try again. Rejecting in the first case makes sense; it is the natural result of the request we just made. However, prompting for more credentials in the second step does not always make sense. We do not know for sure that the caller is going to make a second request, and nor are we sure that it will be to the same URL. Logically, the prompt belongs not to the request we just finished, but to the request we are (maybe) about to make. In practice, it is very hard to trigger any bad behavior. Currently, if we make a second request, it will always be to the same URL (even in the face of redirects, because curl handles the redirects internally). And we almost always retry on HTTP_REAUTH these days. The one exception is if we are streaming a large RPC request to the server (e.g., a pushed packfile), in which case we cannot restart. It's extremely unlikely to see a 401 response at this stage, though, as we would typically have seen it when we sent a probe request, before streaming the data. This patch drops the automatic prompt out of case 2, and instead requires the caller to do it. This is a few extra lines of code, and the bug it fixes is unlikely to come up in practice. But it is conceptually cleaner, and paves the way for better handling of credentials across redirects. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Jonathan Nieder <jrnieder@gmail.com>

We now have a bitfield with multiple boolean options, as well as an optional strbuf for returning the content-type of the response. And a future patch in this series is going to add another strbuf option. Treating these as separate arguments has a few downsides: 1. Most call sites need to add extra NULLs and 0s for the options they aren't interested in. 2. The http_get_* functions are actually wrappers around 2 layers of low-level implementation functions. We have to pass these options through individually. 3. The http_get_strbuf wrapper learned these options, but nobody bothered to do so for http_get_file, even though it is backed by the same function that does understand the options. Let's consolidate the options into a single struct. For the common case of the default options, we'll allow callers to simply pass a NULL for the options struct. The resulting code is often a few lines longer, but it ends up being easier to read (and to change as we add new options, since we do not need to update each call site).
