2014-01-02use distinct username/password for http auth testsLibravatar Jeff King1-3/+3
The httpd server we set up to test git's http client code knows about a single account, in which both the username and password are "user@host" (the unusual use of the "@" here is to verify that we handle the character correctly when URL escaped). This means that we may miss a certain class of errors in which the username and password are mixed up internally by git. We can make our tests more robust by having distinct values for the username and password. In addition to tweaking the server passwd file and the client URL, we must teach the "askpass" harness to accept multiple values. As a bonus, this makes the setup of some tests more obvious; when we are expecting git to ask only about the password, we can seed the username askpass response with a bogus value.

2013-04-13doc/http-backend: match query-string in apache half-auth exampleLibravatar Jeff King1-0/+30
When setting up a "half-auth" repository in which reads can be done anonymously but writes require authentication, it is best if the server can require authentication for both the ref advertisement and the actual receive-pack POSTs. This alleviates the need for the admin to set http.receivepack in the repositories, and means that the client is challenged for credentials immediately, instead of partway through the push process (and git clients older than v1.7.11.7 had trouble handling these challenges). Since detecting a push during the ref advertisement requires matching the query string, and this is non-trivial to do in Apache, we have traditionally punted and instructed users to just protect "/git-receive-pack$". This patch provides the mod_rewrite recipe to actually match the ref advertisement, which is preferred. While we're at it, let's add the recipe to our test scripts so that we can be sure that it works, and doesn't get broken (either by our changes or by changes in Apache).

2012-08-27http: prompt for credentials on failed POSTLibravatar Jeff King1-1/+1
All of the smart-http GET requests go through the http_get_* functions, which will prompt for credentials and retry if we see an HTTP 401. 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.

Some sites set up http access to repositories such that fetching is anonymous and unauthenticated, but pushing is authenticated. 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$".

2012-05-01t5541: test more combinations of --progressLibravatar Jeff King1-2/+25
Previously, we tested only that "push --quiet --no-progress" was silent. However, there are many other combinations that were not tested: 1. no options at all (but stderr as a tty) 2. --no-progress by itself 3. --quiet by itself 4. --progress (when stderr not a tty) These are tested elsewhere for general "push", but it is important to test them separately for http. It follows a very different code path than git://, and options must be relayed across a remote helper to a separate send-pack process (and in fact cases (1), (2), and (4) have all been broken just for http at some point in the past). We can drop the "--quiet --no-progress" test, as it is not really interesting (it is already handled by testing them separately in (2) and (3) above).

2012-03-30http-backend: respect existing GIT_COMMITTER_* variablesLibravatar Jeff King1-0/+21
The http-backend program sets default GIT_COMMITTER_NAME and GIT_COMMITTER_EMAIL variables based on the REMOTE_USER and REMOTE_ADDR variables provided by the webserver. However, it unconditionally overwrites any existing GIT_COMMITTER variables, which may have been customized by site-specific code in the webserver (or in a script wrapping http-backend). Let's leave those variables intact if they already exist, assuming that any such configuration was intentional. There is a slight chance of a regression if somebody has set GIT_COMMITTER_* for the entire webserver, not intending it to leak through http-backend. We could protect against this by passing the information in alternate variables. However, it seems unlikely that anyone will care about that regression, and there is value in the simplicity of using the common variable names that are used elsewhere in git. While we're tweaking the environment-handling in http-backend, let's switch it to use argv_array to handle the list of variables. That makes the memory management much simpler.

2012-01-20remote-curl: Fix push status report when all branches failLibravatar Shawn O. Pearce1-0/+28
The protocol between transport-helper.c and remote-curl requires remote-curl to always print a blank line after the push command has run. If the blank line is ommitted, transport-helper kills its container process (the git push the user started) with exit(128) and no message indicating a problem, assuming the helper already printed reasonable error text to the console. However if the remote rejects all branches with "ng" commands in the report-status reply, send-pack terminates with non-zero status, and in turn remote-curl exited with non-zero status before outputting the blank line after the helper status printed by send-pack. No error messages reach the user. This caused users to see the following from git push over HTTP when the remote side's update hook rejected the branch: $ git push http://... master Counting objects: 4, done. Delta compression using up to 6 threads. Compressing objects: 100% (2/2), done. Writing objects: 100% (3/3), 301 bytes, done. Total 3 (delta 0), reused 0 (delta 0) $ Always print a blank line after the send-pack process terminates, ensuring the helper status report (if it was output) will be correctly parsed by the calling transport-helper.c.

2011-12-19remote-curl: don't pass back fake refsLibravatar Jeff King1-0/+32
When receive-pack advertises its list of refs, it generally hides the capabilities information after a NUL at the end of the first ref. However, when we have an empty repository, there are no refs, and therefore receive-pack writes a fake ref "capabilities^{}" with the capabilities afterwards. On the client side, git reads the result with get_remote_heads(). We pick the capabilities from the end of the line, and then call check_ref() to make sure the ref name is valid. We see that it isn't, and don't bother adding it to our list of refs. However, the call to check_ref() is enabled by passing the REF_NORMAL flag to get_remote_heads. For the regular git transport, we pass REF_NORMAL in get_refs_via_connect() if we are doing a push (since only receive-pack uses this fake ref). But in remote-curl, we never use this flag, and we accept the fake ref as a real one, passing it back from the helper to the parent git-push. Most of the time this bug goes unnoticed, as the fake ref won't match our refspecs. However, if "--mirror" is used, then we see it as remote cruft to be pruned, and try to pass along a deletion refspec for it. Of course this refspec has bogus syntax (because of the ^{}), and the helper complains, aborting the push. Let's have remote-curl mirror what the builtin get_refs_via_connect() does (at least for the case of using git protocol; we can leave the dumb info/refs reader as it is). This also fixes pushing with --mirror to a smart-http remote that uses alternates. The fake ".have" refs the server gives to avoid unnecessary network transfer has a similar bad interactions with the machinery.

2009-11-04test smart http fetch and pushLibravatar Shawn O. Pearce1-0/+92
The top level directory "/smart/" of the test Apache server is mapped through our git-http-backend CGI, but uses the same underlying repository space as the server's document root. This is the most simple installation possible. Server logs are checked to verify the client has accessed only the smart URLs during the test. During fetch testing the headers are also logged from libcurl to ensure we are making a reasonably sane HTTP request, and getting back reasonably sane response headers from the CGI. When validating the request headers used during smart fetch we munge away the actual Content-Length and replace it with the placeholder "xxx". This avoids unnecessary varability in the test caused by an unrelated change in the requested capabilities in the first want line of the request. However, we still want to look for and verify that Content-Length was used, because smaller payloads should be using Content-Length and not "Transfer-Encoding: chunked". When validating the server response headers we must discard both Content-Length and Transfer-Encoding, as Apache2 can use either format to return our response. During development of this test I observed Apache returning both forms, depending on when the processes got CPU time. If our CGI returned the pack data quickly, Apache just buffered the whole thing and returned a Content-Length. If our CGI took just a bit too long to complete, Apache flushed its buffer and instead used "Transfer-Encoding: chunked". Signed-off-by: Shawn O.
