2020-07-30t: remove test_oid_init in testsLibravatar brian m. carlson1-1/+0
Now that we call test_oid_init in the setup for all test scripts, there's no point in calling it individually. Remove all of the places where we've done so to help keep tests tidy.

2019-04-15upload-pack: send ERR packet for non-tip objectsLibravatar Jeff King1-1/+12
Commit bdb31eada7 (upload-pack: report "not our ref" to client, 2017-02-23) catches the case where a client asks for an object we don't have, and issues a message that the client can show to the user (in addition to dying and writing to stderr). There's a similar case (with the same message) when the client asks for an object which we _do_ have, but which isn't a ref tip (or isn't reachable, when uploadpack.allowReachableSHA1InWant is true). Let's give that one the same treatment, for the same reason (namely that it's more informative to the client than just hanging up, since they won't see our stderr over some protocols). There are two tests here. We cover it most directly in t5530 by invoking upload-pack, which matches the existing "not our ref" test. But a more end-to-end check is that "git fetch" actually shows the message to the client. We're already checking in t5516 that this case fails, so we can just check stderr there, too. Note that even after we started ignoring SIGPIPE in 8bf4becf0c, this could in theory still be racy as described in that commit (because we die() on write failures before pumping the connection for any ERR packets). In practice this should be OK for this case. The server will not actually check reachability until it has received our whole group of "want" lines. And since we have no objects in the repository, we won't send any "have" lines, meaning we're always waiting to read the server response. Note also that this case cannot happen in the v2 protocol, since it allows any available object to be requested. However, we don't have to take any steps to protect against the upcoming GIT_TEST_PROTOCOL_VERSION in our tests: - the tests in t5516 would already need to be skipped under v2, and that is covered by ab0c5f5096 (tests: always test fetch of unreachable with v0, 2019-02-25) - the tests in t5530 invoke upload-pack directly, which will continue to default to v0. Eventually we may have a test setting which uses v2 even for bare upload-pack calls, but we can't override it here until we know what the setting looks like.

2019-04-15t5530: check protocol response for "not our ref"Libravatar Jeff King1-2/+3
Back in 9f9aa76130 (upload-pack: Improve error message when bad ref requested, 2010-07-31), we added a test to make sure that we die with a sensible message when the client asks for an object we don't have. Much later, in bdb31eada7 (upload-pack: report "not our ref" to client, 2017-02-23), we started reporting that information via an "ERR" line in the protocol. Let's check that part, as well. While we're touching this test, let's drop the "-q" on the grep calls. Our usual test style just relies on --verbose to control output.

2016-01-04t/t5530-upload-pack-error.sh: use the $( ... ) construct for command ↵Libravatar Elia Pinto1-1/+1
substitution The Git CodingGuidelines prefer the $(...) construct for command substitution instead of using the backquotes `...`. The backquoted form is the traditional method for command substitution, and is supported by POSIX. However, all but the simplest uses become complicated quickly. In particular, embedded command substitutions and/or the use of double quotes require careful escaping with the backslash character. The patch was generated by: for _f in $(find . -name "*.sh") do perl -i -pe 'BEGIN{undef $/;} s/`(.+?)`/\$(\1)/smg' "${_f}" done and then carefully proof-read.

2013-08-28upload-pack: delegate rev walking in shallow fetch to pack-objectsLibravatar Nguyễn Thái Ngọc Duy1-3/+0
upload-pack has a special revision walking code for shallow recipients. It works almost like the similar code in pack-objects except: 1. in upload-pack, graft points could be added for deepening; 2. also when the repository is deepened, the shallow point will be moved further away from the tip, but the old shallow point will be marked as edge to produce more efficient packs. See 6523078 (make shallow repository deepening more network efficient - 2009-09-03). Pass the file to pack-objects via --shallow-file. This will override $GIT_DIR/shallow and give pack-objects the exact repository shape that upload-pack has. mark edge commits by revision command arguments. Even if old shallow points are passed as "--not" revisions as in this patch, they will not be picked up by mark_edges_uninteresting() because this function looks up to parents for edges, while in this case the edge is the children, in the opposite direction. This will be fixed in an later patch when all given uninteresting commits are marked as edges.

* js/run-command-updates: api-run-command.txt: describe error behavior of run_command functions run-command.c: squelch a "use before assignment" warning receive-pack: remove unnecessary run_status report run_command: report failure to execute the program, but optionally don't run_command: encode deadly signal number in the return value run_command: report system call errors instead of returning error codes run_command: return exit code as positive value MinGW: simplify waitpid() emulation macros
2009-07-06run_command: report system call errors instead of returning error codesLibravatar Johannes Sixt1-1/+4
The motivation for this change is that system call failures are serious errors that should be reported to the user, but only few callers took the burden to decode the error codes that the functions returned into error messages. If at all, then only an unspecific error message was given. A prominent example is this: $ git upload-pack . | : fatal: unable to run 'git-upload-pack' In this example, git-upload-pack, the external command invoked through the git wrapper, dies due to SIGPIPE, but the git wrapper does not bother to report the real cause. In fact, this very error message is copied to the syslog if git-daemon's client aborts the connection early. With this change, system call failures are reported immediately after the failure and only a generic failure code is returned to the caller. In the above example the error is now to the point: $ git upload-pack . | : error: git-upload-pack died of signal Note that there is no error report if the invoked program terminated with a non-zero exit code, because it is reasonable to expect that the invoked program has already reported an error. (But many run_command call sites nevertheless write a generic error message.) There was one special return code that was used to identify the case where run_command failed because the requested program could not be exec'd. This special case is now treated like a system call failure with errno set to ENOENT. No error is reported in this case, because the call site in git.c expects this as a normal result. Therefore, the callers that carefully decoded the return value still check for this condition. Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-06-09Shift object enumeration out of upload-packLibravatar Nick Edelen1-2/+12
Offload object enumeration in upload-pack to pack-objects, but fall back on internal revision walker for shallow interaction. Aside from architecturally making more sense, this also leaves the door open for pack-objects to employ a revision cache mechanism. Test t5530 updated in order to explicitly check both enumeration methods.

2008-07-13t/: Use "test_must_fail git" instead of "! git"Libravatar Stephan Beyer1-3/+3
This patch changes every occurrence of "! git" -- with the meaning that a git call has to gracefully fail -- into "test_must_fail git". This is useful to - make sure the test does not fail because of a signal, e.g. SIGSEGV, and - advertise the use of "test_must_fail" for new tests.

2008-02-01Sane use of test_expect_failureLibravatar Junio C Hamano1-8/+6
Originally, test_expect_failure was designed to be the opposite of test_expect_success, but this was a bad decision. Most tests run a series of commands that leads to the single command that needs to be tested, like this: test_expect_{success,failure} 'test title' ' setup1 && setup2 && setup3 && what is to be tested ' And expecting a failure exit from the whole sequence misses the point of writing tests. Your setup$N that are supposed to succeed may have failed without even reaching what you are trying to test. The only valid use of test_expect_failure is to check a trivial single command that is expected to fail, which is a minority in tests of Porcelain-ish commands. This large-ish patch rewrites all uses of test_expect_failure to use test_expect_success and rewrites the condition of what is tested, like this: test_expect_success 'test title' ' setup1 && setup2 && setup3 && ! this command should fail ' test_expect_failure is redefined to serve as a reminder that that test *should* succeed but due to a known breakage in git it currently does not pass. So if git-foo command should create a file 'bar' but you discovered a bug that it doesn't, you can write a test like this: test_expect_failure 'git-foo should create bar' ' rm -f bar && git foo && test -f bar ' This construct acts similar to test_expect_success, but instead of reporting "ok/FAIL" like test_expect_success does, the outcome is reported as "FIXED/still broken".

2007-11-05upload-pack: Use finish_{command,async}() instead of waitpid().Libravatar Johannes Sixt1-0/+75
upload-pack spawns two processes, rev-list and pack-objects, and carefully monitors their status so that it can report failure to the remote end. This change removes the complicated procedures on the grounds of the following observations: - If everything is OK, rev-list closes its output pipe end, upon which pack-objects (which reads from the pipe) sees EOF and terminates itself, closing its output (and error) pipes. upload-pack reads from both until it sees EOF in both. It collects the exit codes of the child processes (which indicate success) and terminates successfully. - If rev-list sees an error, it closes its output and terminates with failure. pack-objects sees EOF in its input and terminates successfully. Again upload-pack reads its inputs until EOF. When it now collects the exit codes of its child processes, it notices the failure of rev-list and signals failure to the remote end. - If pack-objects sees an error, it terminates with failure. Since this breaks the pipe to rev-list, rev-list is killed with SIGPIPE. upload-pack reads its input until EOF, then collects the exit codes of the child processes, notices their failures, and signals failure to the remote end. - If upload-pack itself dies unexpectedly, pack-objects is killed with SIGPIPE, and subsequently also rev-list. The upshot of this is that precise monitoring of child processes is not required because both terminate if either one of them dies unexpectedly. This allows us to use finish_command() and finish_async() instead of an explicit waitpid(2) call. The change is smaller than it looks because most of it only reduces the indentation of a large part of the inner loop.
