2021-11-01leak tests: mark some config tests as passing with SANITIZE=leakLibravatar Ævar Arnfjörð Bjarmason1-0/+1
Mark some tests that match "*config*" as passing when git is compiled with SANITIZE=leak. They'll now be listed as running under the "GIT_TEST_PASSING_SANITIZE_LEAK=true" test mode (the "linux-leaks" CI target).

2020-11-19t1309: use a neutral branch name in the `onbranch` test casesLibravatar Johannes Schindelin1-2/+2
The `onbranch` test cases touched by this patch do not actually try to include any other config. Their purpose is to avoid regressing on two bugs in the `include.onbranch:<name>.path` code that we fixed in the past, bugs that are actually unrelated to any concrete branch name. The first bug was fixed in 85fe0e800ca (config: work around bug with includeif:onbranch and early config, 2019-07-31). Essentially, when reading early config, there would be a catch-22 trying to access the refs, and therefore we simply cannot evaluate the condition at that point. The test case ensures that we avoid emitting this bogus message: BUG: refs.c:1851: attempting to get main_ref_store outside of repository The second test case concerns the non-Git scenario, where we simply do not have a current branch to begin with (because we don't have a repository in the first place), and the test case was introduced in 22932d9169f (config: stop checking whether the_repository is NULL, 2019-08-06) to ensure that we don't cause a segmentation fault should the code still incorrectly try to look at any ref. In short, neither of these two test cases will ever look at a current branch name, even in case of regressions. Therefore, the actual branch name does not matter at all. We can therefore easily avoid racially-charged branch names here, and that's what this patch does.

2019-11-27test: use test_must_be_empty F instead of test -z $(cat F)Libravatar René Scharfe1-1/+1
Use test_must_be_empty instead of reading the file and comparing its contents to an empty string. That's more efficient, as the function only needs built-in meta-data only check in the usual case, and provides nicer debug output otherwise.

2019-08-06config: stop checking whether the_repository is NULLLibravatar Jeff King1-0/+5
Since the previous commit, our invariant that the_repository is never NULL is restored, and we can stop being defensive in include_by_branch(). We can confirm the fix by showing that an onbranch config include will not cause a segfault when run outside a git repository. I've put this in t1309-early-config since it's related to the case added by 85fe0e800c (config: work around bug with includeif:onbranch and early config, 2019-07-31), though technically the issue was with read_very_early_config() and not read_early_config().

2019-08-06t1309: use short branch name in includeIf.onbranch testLibravatar Jeff King1-1/+1
Commit 85fe0e800c (config: work around bug with includeif:onbranch and early config, 2019-07-31) tests that our early config-reader does not access the file mentioned by includeIf.onbranch:refs/heads/master.path. But it would never do so even if the feature were implemented, since the onbranch matching code uses the short refname "master". The test still serves its purpose, since the bug fixed by 85fe0e800c is actually that we hit a BUG() before even deciding whether to match the ref. But let's use the correct name to avoid confusion (and which we'll eventually want to trigger once we do the "real" fix described in that commit).

2019-07-31config: work around bug with includeif:onbranch and early configLibravatar Johannes Schindelin1-0/+5
Since 07b2c0eacac (config: learn the "onbranch:" includeIf condition, 2019-06-05), there is a potential catch-22 in the early config path: if the `include.onbranch:` feature is used, Git assumes that the Git directory has been initialized already. However, in the early config code path that is not true. One way to trigger this is to call the following commands in any repository: git config includeif.onbranch:refs/heads/master.path broken git help -a The symptom triggered by the `git help -a` invocation reads like this: BUG: refs.c:1851: attempting to get main_ref_store outside of repository Let's work around this, simply by ignoring the `includeif.onbranch:` setting when parsing the config when the ref store has not been initialized (yet). Technically, there is a way to solve this properly: teach the refs machinery to initialize the ref_store from a given gitdir/commondir pair (which we _do_ have in the early config code path), and then use that in `include_by_branch()`. This, however, is a pretty involved project, and we're already in the feature freeze for Git v2.23.0. Note: when calling above-mentioned two commands _outside_ of any Git worktree (passing the `--global` flag to `git config`, as there is obviously no repository config available), at the point when `include_by_branch()` is called, `the_repository` is `NULL`, therefore we have to be extra careful not to dereference it in that case.

2017-05-11tests: fix tests broken under GETTEXT_POISON=YesPleaseLibravatar Ævar Arnfjörð Bjarmason1-1/+1
The GETTEXT_POISON=YesPlease compile-time testing option added in my bb946bba76 ("i18n: add GETTEXT_POISON to simulate unfriendly translator", 2011-02-22) has been slowly bitrotting as strings have been marked for translation, and new tests have been added without running it. I brought this up on the list ("[BUG] test suite broken with GETTEXT_POISON=YesPlease", [1]) asking whether this mode was useful at all anymore. At least one person occasionally uses it, and Lars Schneider offered to change one of the the Travis builds to run in this mode, so fix up the failing ones. My test setup runs most of the tests, with the notable exception of skipping all the p4 tests, so it's possible that there's still some lurking regressions I haven't fixed. 1. <CACBZZX62+acvi1dpkknadTL827mtCm_QesGSZ=6+UnyeMpg8+Q@mail.gmail.com> Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-04-19config: correct file reading order in read_early_config()Libravatar Nguyễn Thái Ngọc Duy1-0/+18
Config file reading order is important because each file can override values in the previous files and this is expected behavior. Normally we read in this order, all in do_git_config_sequence(): 1. $HOME/.gitconfig 2. $GIT_DIR/config 3. config from command line However in read_early_config() the order may be swapped a bit if setup_git_directory() has not been called: 1. $HOME/.gitconfig 2. $GIT_DIR/config is NOT read because .git dir is not found _yet_ 3. config from command line 4. $GIT_DIR/config is now READ (after discover_git_directory() call) The reading at step 4 could override config at step 3, which is not the expectation. Now that we could pass the .git dir around, we could feed discover_git_directory() back to step 2, so that it works again, and remove step 4.

2017-03-14t1309: document cases where we would want early config not to die()Libravatar Johannes Schindelin1-0/+24
Jeff King came up with a couple examples that demonstrate how the new read_early_config() that looks harder for the current .git/ directory could die() in an undesirable way. Let's add those cases to the test script, to document what we would like to happen when early config encounters problems.
