test smart http fetch and push 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.

signed push: teach smart-HTTP to pass "git push --signed" around The "--signed" option received by "git push" is first passed to the transport layer, which the native transport directly uses to notice that a push certificate needs to be sent. When the transport-helper is involved, however, the option needs to be told to the helper with set_helper_option(), and the helper needs to take necessary action. For the smart-HTTP helper, the "necessary action" involves spawning the "git send-pack" subprocess with the "--signed" option. Once the above all gets wired in, the smart-HTTP transport now can use the push certificate mechanism to authenticate its pushes. Add a test that is modeled after tests for the native transport in t5534-push-signed.sh to t5541-http-push-smart.sh. Update the test Apache configuration to pass GNUPGHOME environment variable through. As PassEnv would trigger warnings for an environment variable that is not set, export it from test-lib.sh set to a harmless value when GnuPG is not being used in the tests. Note that the added test is deliberately loose and does not check the nonce in this step. This is because the stateless RPC mode is inevitably flaky and a nonce that comes back in the actual push processing is one issued by a different process; if the two interactions with the server crossed a second boundary, the nonces will not match and such a check will fail. A later patch in the series will work around this shortcoming. Signed-off-by: Junio C Hamano <gitster@pobox.com>

t/lib-httpd: avoid occasional failures when checking access.log The last test of 't5561-http-backend.sh', 'server request log matches test results' may fail occasionally, because the order of entries in Apache's access log doesn't match the order of requests sent in the previous tests, although all the right requests are there. I saw it fail on Travis CI five times in the span of about half a year, when the order of two subsequent requests was flipped, and could trigger the failure with a modified Git. However, I was unable to trigger it with stock Git on my machine. Three tests in 't5541-http-push-smart.sh' and 't5551-http-fetch-smart.sh' check requests in the log the same way, so they might be prone to a similar occasional failure as well. When a test sends a HTTP request, it can continue execution after 'git-http-backend' fulfilled that request, but Apache writes the corresponding access log entry only after 'git-http-backend' exited. Some time inevitably passes between fulfilling the request and writing the log entry, and, under unfavourable circumstances, enough time might pass for the subsequent request to be sent and fulfilled by a different Apache thread or process, and then Apache writes access log entries racily. This effect can be exacerbated by adding a bit of variable delay after the request is fulfilled but before 'git-http-backend' exits, e.g. like this: diff --git a/http-backend.c b/http-backend.c index f3dc218b2..bbf4c125b 100644 --- a/http-backend.c +++ b/http-backend.c @@ -709,5 +709,7 @@ int cmd_main(int argc, const char **argv) max_request_buffer); cmd->imp(&hdr, cmd_arg); + if (getpid() % 2) + sleep(1); return 0; } This delay considerably increases the chances of log entries being written out of order, and in turn makes t5561's last test fail almost every time. Alas, it doesn't seem to be enough to trigger a similar failure in t5541 and t5551. So, since we can't just rely on the order of access log entries always corresponding the order of requests, make checking the access log more deterministic by sorting (simply lexicographically) both the stripped access log entries and the expected entries before the comparison with 'test_cmp'. This way the order of log entries won't matter and occasional out-of-order entries won't trigger a test failure, but the comparison will still notice any unexpected or missing log entries. OTOH, this sorting will make it harder to identify from which test an unexpected log entry came from or which test's request went missing. Therefore, in case of an error include the comparison of the unsorted log enries in the test output as well. And since all this should be performed in four tests in three test scripts, put this into a new helper function 'check_access_log' in 't/lib-httpd.sh'.

remote-curl: don't pass back fake refs 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.

http: prompt for credentials on failed POST 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.

signed push: teach smart-HTTP to pass "git push --signed" around The "--signed" option received by "git push" is first passed to the transport layer, which the native transport directly uses to notice that a push certificate needs to be sent. When the transport-helper is involved, however, the option needs to be told to the helper with set_helper_option(), and the helper needs to take necessary action. For the smart-HTTP helper, the "necessary action" involves spawning the "git send-pack" subprocess with the "--signed" option. Once the above all gets wired in, the smart-HTTP transport now can use the push certificate mechanism to authenticate its pushes. Add a test that is modeled after tests for the native transport in t5534-push-signed.sh to t5541-http-push-smart.sh. Update the test Apache configuration to pass GNUPGHOME environment variable through. As PassEnv would trigger warnings for an environment variable that is not set, export it from test-lib.sh set to a harmless value when GnuPG is not being used in the tests. Note that the added test is deliberately loose and does not check the nonce in this step. This is because the stateless RPC mode is inevitably flaky and a nonce that comes back in the actual push processing is one issued by a different process; if the two interactions with the server crossed a second boundary, the nonces will not match and such a check will fail. A later patch in the series will work around this shortcoming. Signed-off-by: Junio C Hamano <gitster@pobox.com>

In addition, the server operator can set receive.certnonceslop configuration variable to specify how stale a nonce can be (in seconds).

test smart http fetch and push 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.
