t5561: skip tests if curl is not available It's possible to have libcurl installed but not the curl command-line utility. The latter is not generally needed for Git's http support, but we use it in t5561 for basic tests of http-backend's functionality. Let's detect when it's missing and skip this test. Note that we can't mark the individual tests with the CURL prerequisite. They're in a shared t556x_common that uses the GET and POST functions as a level of indirection, and it's only our implementations of those functions in t5561 that requires curl. It's not a problem, though, as literally every test in the script would depend on the prerequisite anyway.

http-backend: Protect GIT_PROJECT_ROOT from /../ requests Eons ago HPA taught git-daemon how to protect itself from /../ attacks, which Junio brought back into service in d79374c7b58d ("daemon.c and path.enter_repo(): revamp path validation"). I did not carry this into git-http-backend as originally we relied only upon PATH_TRANSLATED, and assumed the HTTP server had done its access control checks to validate the resolved path was within a directory permitting access from the remote client. This would usually be sufficient to protect a server from requests for its /etc/passwd file by http://host/smart/../etc/passwd sorts of URLs. However in 917adc036086 Mark Lodato added GIT_PROJECT_ROOT as an additional method of configuring the CGI. When this environment variable is used the web server does not generate the final access path and therefore may blindly pass through "/../etc/passwd" in PATH_INFO under the assumption that "/../" might have special meaning to the invoked CGI. Instead of permitting these sorts of malformed path requests, we now reject them back at the client, with an error message for the server log. This matches git-daemon behavior.

t5561: get rid of racy appending to logfile The definition of log_div() appended information to the web server's logfile to make the test more readable. However, log_div() was called right after a request is served (which is done by git-http-backend); the web server waits for the git-http-backend process to exit before it writes to the log file. When the duration between serving a request and exiting was long, the log_div() output was written before the last request's log, and the test failed. (This duration could become especially long for PROFILE=GEN builds.) To get rid of this behavior, we should not change the logfile at all. This commit removes log_div() and its calls. The additional information is kept in the test (for readability reasons) but filtered out before comparing it to the actual logfile.

Smart-http: check if repository is OK to export before serving it Similar to how git-daemon checks whether a repository is OK to be exported, smart-http should also check. This check can be satisfied in two different ways: the environmental variable GIT_HTTP_EXPORT_ALL may be set to export all repositories, or the individual repository may have the file git-daemon-export-ok.

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'.
