2019-03-14tests: use 'test_atexit' to stop httpdSZEDER Gábor
Use 'test_atexit' to run cleanup commands to stop httpd at the end of the test script or upon interrupt or failure, as it is shorter, simpler, and more robust than registering such cleanup commands in the trap on EXIT in the test scripts.

2018-07-12t/lib-httpd: avoid occasional failures when checking access.logSZEDER Gábor
The last test of '', '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 '' and '' 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/'.

2018-07-12t/lib-httpd: add the strip_access_log() helper functionSZEDER Gábor
Four tests in three httpd-related test scripts check the contents of Apache's 'access.log', and they all do so by running 'sed' with the exact same script consisting of four s/// commands to strip uninteresting log fields and to vertically align the requested URLs. Extract this into a common helper function 'strip_access_log' in '', and use it in all of those tests. Signed-off-by: SZEDER Gábor <> Signed-off-by: Junio C Hamano <>
2018-04-05t5561: skip tests if curl is not availableJeff King
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. Reported-by: Jens Krüger <> Signed-off-by: Jeff King <> Signed-off-by: Junio C Hamano <>
2018-04-05t5561: drop curl stderr redirectsJeff King
For a normal test run, stderr is already redirected to /dev/null by the test suite. When used with "-v", suppressing stderr is actively harmful, as it may hide the reason for curl failing. Reported-by: Jens Krüger <> Signed-off-by: Jeff King <> Signed-off-by: Junio C Hamano <>
2015-10-15Merge branch 'sb/http-flaky-test-fix'Junio C Hamano
A test script for the HTTP service had a timing dependent bug, which was fixed. * sb/http-flaky-test-fix: t5561: get rid of racy appending to logfile
2015-09-25t5561: get rid of racy appending to logfileStephan Beyer
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.

2015-05-07t/ skip tests if NO_CURL is definedJeff King
If we built git without curl, we can't actually test against an http server. In fact, all of the test scripts which include already perform this check, with one exception: t5540. For those scripts, this is a noop, and for t5540, this is a bugfix (it used to fail when built with NO_CURL, though it could go unnoticed if you had a stale git-remote-https in your build directory).

2014-02-10tests: auto-set LIB_HTTPD_PORT from test nameJeff King
We set the default apache port for each of the httpd tests to the 4-digit test number of the test script. We want these to remain unique so that the tests do not conflict with each other when run in parallel. Instead of doing it manually in each test script, let's just set it from the test name at run time. This is simpler, and is one less thing to be updated when test scripts are renamed (e.g., when being re-rolled or when conflicting after being merged with another topic). Incidentally, this fixes a case where t5537 and t5538 used the same port number (5537), and could conflict with each other when run in parallel.

2010-06-25tests: Skip tests in a way that makes sense under TAPÆvar Arnfjörð Bjarmason
SKIP messages are now part of the TAP plan. A TAP harness now knows why a particular test was skipped and can report that information. The non-TAP harness built into Git's test-lib did nothing special with these messages, and is unaffected by these changes. Signed-off-by: Ævar Arnfjörð Bjarmason <> Signed-off-by: Junio C Hamano <>
