2020-01-15test: request GIT_TEST_PROTOCOL_VERSION=0 when appropriateJonathan Nieder
Since 8cbeba0632 (tests: define GIT_TEST_PROTOCOL_VERSION, 2019-02-25), it has been possible to run tests with a newer protocol version by setting the GIT_TEST_PROTOCOL_VERSION envvar to a version number. Tests that assume protocol v0 handle this by explicitly setting GIT_TEST_PROTOCOL_VERSION= or similar constructs like 'test -z "$GIT_TEST_PROTOCOL_VERSION" || return 0' to declare that they only handle the default (v0) protocol. The emphasis there is a bit off: it would be clearer to specify GIT_TEST_PROTOCOL_VERSION=0 to inform the reader that these tests are specifically testing and relying on details of protocol v0. Do so. This way, a reader does not need to know what the default protocol version is, and the tests can continue to work when the default protocol version used by Git advances past v0.

2019-03-07tests: define GIT_TEST_PROTOCOL_VERSIONJonathan Tan
Define a GIT_TEST_PROTOCOL_VERSION environment variable meant to be used from tests. When set, this ensures protocol.version is at least the given value, allowing the entire test suite to be run as if this configuration is in place for all repositories. As of this patch, all tests pass whether GIT_TEST_PROTOCOL_VERSION is unset or set to 0. Some tests fail when GIT_TEST_PROTOCOL_VERSION is set to 1 or 2, but this will be dealt with in subsequent patches. This is based on work by Ævar Arnfjörð Bjarmason.

2018-07-03t: use test_might_fail() instead of manipulating exit code manuallyEric Sunshine
These tests manually coerce the exit code of invoked commands to "success" when they don't care if the command succeeds or fails since failure of those commands should not cause the test to fail overall. In doing so, they intentionally break the &&-chain. Modernize by replacing manual exit code management with test_might_fail() and a normal &&-chain.

2017-05-18t5400: avoid concurrent writes into a trace fileJeff King
One test in t5400 examines the packet exchange between git-push and git-receive-pack. The latter inherits the GIT_TRACE_PACKET environment variable, so that both processes dump trace data into the same file concurrently. This should not be a problem because the trace file is opened with O_APPEND. On Windows, however, O_APPEND is not atomic as it should be: it is emulated as lseek(SEEK_END) followed by write(). For this reason, the test is unreliable: it can happen that one process overwrites a line that was just written by the other process. As a consequence, the test sometimes does not find one or another line that is expected (and it is also successful occasionally). The test case is actually only interested in the output of git-push. To ensure that only git-push writes to the trace file, override the receive-pack command such that it does not even open the trace file.

2017-02-08receive-pack: avoid duplicates between our refs and alternatesJeff King
We de-duplicate ".have" refs among themselves, but never check if they are duplicates of our local refs. It's not unreasonable that they would be if we are a "--shared" or "--reference" clone of a similar repository; we'd have all the same tags. We can handle this by inserting our local refs into the oidset, but obviously not suppressing duplicates (since the refnames are important). Note that this also switches the order in which we advertise refs, processing ours first and then any alternates. The order shouldn't matter (and arguably showing our refs first makes more sense).

2016-03-31git-send-pack: fix --all option when used with directoryStanislav Kolotinskiy
When using git send-pack with --all option and a target repository specification ([<host>:]<directory>), usage message is being displayed instead of performing the actual transmission. The reason for this issue is that destination and refspecs are being set in the same conditional and are populated from argv. When a target repository is passed, refspecs is being populated as well with its value. This makes the check for refspecs not being NULL to always return true, which, in conjunction with the check for --all or --mirror options, is always true as well and returns usage message instead of proceeding. This ensures that send-pack will stop execution only when --all or --mirror switch is used in conjunction with any refspecs passed.

2012-08-07receive-pack: do not leak output from auto-gc to standard outputJunio C Hamano
The standard output channel of receive-pack is a structured protocol channel, and subprocesses must never be allowed to leak anything into it by writing to their standard output. Use RUN_COMMAND_STDOUT_TO_STDERR option to run_command_v_opt() just like we do when running hooks to prevent output from "gc" leaking to the standard output. Signed-off-by: Junio C Hamano <>
2012-08-07t/t5400: demonstrate breakage caused by informational message from pruneBrandon Casey
When receive-pack triggers 'git gc --auto' and 'git prune' is called to remove a stale temporary object, 'git prune' prints an informational message to stdout about the file that it will remove. Since this message is written to stdout, it is sent back over the transport channel to the git client which tries to interpret it as part of the pack protocol and then promptly terminates with a complaint about a protocol error. Introduce a test which exercises the auto-gc functionality of receive-pack and demonstrates this breakage. Signed-off-by: Brandon Casey <> Signed-off-by: Junio C Hamano <>

2009-07-29Refuse updating the current branch in a non-bare repository via pushJunio C Hamano
This makes git-push refuse pushing into a non-bare repository to update the current branch by default. To help people who are used to be able to do this (and later "reset --hard" it in some other way), an error message is issued when this refusal is triggered, instructing how to resurrect the old behaviour. Hosting sites that do not give the users direct access to customize their repositories (e.g., gitorious, github etc.) may further want to explicitly set the configuration variable to "refuse" for their customers' repositories.

2009-02-11receive-pack: receive.denyDeleteCurrentJunio C Hamano
This is a companion patch to the recent 3d95d92 (receive-pack: explain what to do when push updates the current branch, 2009-01-31). Deleting the current branch from a remote will result in the next clone from it not check out anything, among other things. It also is one of the cause that makes remotes/origin/HEAD a dangling symbolic ref. This patch still allows the traditional behaviour but with a big warning, and promises that the default will change to 'refuse' in a future release. Signed-off-by: Junio C Hamano <>
2009-02-11Modernize t5400 test scriptJunio C Hamano
Many tests checked for failure by hand without using test_must_fail (they probably predate the shell function). When we know the desired outcome, explicitly check for it, instead of checking if the result does not match one possible incorrect outcome. E.g. if you expect a push to be refused, you do not test if the result is different from what was pushed. Instead, make sure that the ref did not before and after the push. The test sequence chdir'ed around and any failure at one point could have started the next test in an unexpected directory. Fix this problem by using subshells as necessary.

2008-05-24tests: do not use implicit "git diff --no-index"Junio C Hamano
As a general principle, we should not use "git diff" to validate the results of what git command that is being tested has done.

2008-03-13grep portability fix: don't use "-e" or "-q"Jeff King
System V versions of grep (such as Solaris /usr/bin/grep) don't understand either of these options. git's usage of "grep -e pattern" fell into one of two categories: 1. equivalent to "grep pattern". -e is only useful here if the pattern begins with a "-", but all of the patterns are hardcoded and do not begin with a dash. 2. stripping comments and blank lines with grep -v -e "^$" -e "^#" We can fortunately do this in the affirmative as grep '^[^#]' Uses of "-q" can be replaced with redirection to /dev/null. In many tests, however, "grep -q" is used as "if this string is in the expected output, we are OK". In this case, it is fine to just remove the "-q" entirely; it simply makes the "verbose" mode of the test slightly more verbose. Signed-off-by: Jeff King <> Signed-off-by: Junio C Hamano <>

2007-03-07Refactor handling of error_string in receive-packShawn O. Pearce
I discovered we did not send an ng line in the report-status feedback if the ref was not updated because the repository has the config option receive.denyNonFastForwards enabled. I think the reason this happened is that it is simply too easy to forget to set error_string when returning back a failure from update() We now return an ng line for a non-fastforward update, which in turn will cause send-pack to exit with a non-zero exit status. Hence the modified test. This refactoring changes update to return a const char* describing the error, which execute_commands always loads into error_string. The result is what I think is cleaner code, and allows us to initialize the error_string member to NULL when we read_head_info. I want error_string to be NULL in all commands before we call execute_commands, so that we can reuse the run_hook function to execute a new pre-receive hook. Signed-off-by: Shawn O.

As promised, this is the "big tool rename" patch. The primary differences since 0.99.6 are: (1) git-*-script are no more.

(2) Many command names with 'cache' in them are renamed with 'index' if that is what they mean. There are backward compatibility symblic links so that you and Porcelains can keep using the old names, but the backward compatibility support is expected to be removed in the near future.

2005-08-12[PATCH] Trapping exit in tests, using return for errorsPavel Roskin
I have noticed that "make test" fails without any explanations when the "merge" utility is missing. I don't think tests should be silent in case of failure. It turned out that the particular test was using "exit" to interrupt the test in case of an error. This caused the whole test script to exit. No further tests would be run even if "--immediate" wasn't specified. No error message was printed. This patch does following: All instances of "exit", "exit 1" and "(exit 1)" in tests have been replaced with "return 1". In fact, "(exit 1)" had no effect. File descriptor 5 is duplicated from file descriptor 1. This is needed to print important error messages from tests. New function test_run_() has been introduced. Any "return" in the test would merely cause that function to return without skipping calls to test_failure_() and test_ok_(). The new function also traps "exit" and treats it like a fatal error (in case somebody reintroduces "exit" in the tests). test_expect_failure() and test_expect_success() check both the result of eval and the return value of test_run_(). If the later is not 0, it's always a failure because it indicates the the test didn't complete. Signed-off-by: Pavel Roskin <> Signed-off-by: Junio C Hamano <>
