2021-10-29Revert "logmsg_reencode(): warn when iconv() fails"Libravatar Junio C Hamano1-7/+0
This reverts commit fd680bc5 (logmsg_reencode(): warn when iconv() fails, 2021-08-27). Throwing a warning for each and every commit that gets reencoded, without allowing a way to squelch, would make it unpleasant for folks who have to deal with an ancient part of the history in an old project that used wrong encoding in the commits.
2021-10-28add, rm, mv: fix bug that prevents the update of non-sparse dirsLibravatar Matheus Tavares3-5/+73
These three commands recently learned to avoid updating paths outside the sparse checkout even if they are missing the SKIP_WORKTREE bit. This is done using path_in_sparse_checkout(), which checks whether a given path matches the current list of sparsity rules, similar to what clear_ce_flags() does when we run "git sparse checkout init" or "git sparse-checkout reapply". However, clear_ce_flags() uses a recursive approach, applying the match results from parent directories on paths that get the UNDECIDED result, whereas path_in_sparse_checkout() only attempts to match the full path and immediately considers UNDECIDED as NOT_MATCHED. This makes the function miss matches with leading directories. For example, if the user has the sparsity patterns "!/a" and "b/", add, rm, and mv will fail to update the path "a/b/c" and end up displaying a warning about it being outside the sparse checkout even though it isn't. This problem only occurs in full pattern mode as the pattern matching functions never return UNDECIDED for cone mode. To fix this, replicate the recursive behavior of clear_ce_flags() in path_in_sparse_checkout(), falling back to the parent directory match when a path gets the UNDECIDED result. (If this turns out to be too expensive in some cases, we may want to later add some form of caching to accelerate multiple queries within the same directory. This is not implemented in this patch, though.) Also add two tests for each affected command (add, rm, and mv) to check that they behave correctly with the recursive pattern matching. The first test would previously fail without this patch while the second already succeeded. It is added mostly to make sure that we are not breaking the existing pattern matching for directories that are really sparse, and also as a protection against any future regressions. Two other existing tests had to be changed as well: one test in t3602 checks that "git rm -r <dir>" won't remove sparse entries, but it didn't allow the non-sparse entries inside <dir> to be removed. The other one, in t7002, tested that "git mv" would correctly display a warning message for sparse paths, but it accidentally expected the message to include two non-sparse paths as well.

2021-10-25userdiff-cpp: back out the digit-separators in numbersLibravatar Johannes Sixt3-15/+15
The implementation of digit-separating single-quotes introduced a note-worthy regression: the change of a character literal with a digit would splice the digit and the closing single-quote. For example, the change from 'a' to '2' is now tokenized as '[-a'-]{+2'+} instead of '[-a-]{+2+}'. The options to fix the regression are: - Tighten the regular expression such that the single-quote can only occur between digits (that would match the official syntax). - Remove support for digit separators. I chose to remove support, because - I have not seen a lot of code make use of digit separators. - If code does use digit separators, then the numbers are typically long. If a change in one of the segments occurs, it is actually better visible if only that segment is highlighted as the word that changed instead of the whole long number. This choice does introduce another minor regression, though, which is highlighted in the test case: when a change occurs in the second or later segment of a hexadecimal number where the segment begins with a digit, but also has letters, the segment is mistaken as consisting of a number and an identifier. I can live with that. Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-10-23grep: fix a "path_list" memory leakLibravatar Ævar Arnfjörð Bjarmason1-1/+2
Free the "path_list" used in builtin/grep.c, it was declared as STRING_LIST_INIT_NODUP, let's change it to a STRING_LIST_INIT_DUP since an early user in cmd_grep() appends a string passed via parse-options.c to it, which needs to be duplicated. Let's then convert the remaining callers to use string_list_append_nodup() instead, allowing us to free the list. This makes all the tests in t7811-grep-open.sh pass, 6/10 would fail before this change. The only remaining failure would have been due to a stray "git checkout" (which still leaks memory). In this case we can use a "git reset --hard" instead, so let's do that, and move the test_when_finished() above the code that would modify the relevant file.

2021-10-18transport-helper: recognize "expecting report" error from send-packLibravatar Jeff King1-1/+1
When a transport helper pushes via send-pack, it passes --helper-status to get a machine-readable status back for each ref. The previous commit taught the send-pack code to hand back "error expecting report" if the server did not send us the proper ref-status. And that's enough to cause us to recognize that an error occurred for the ref and print something sensible in our final status table. But we do interpret these messages on the remote-helper side to turn them back into REF_STATUS_* enum values. Recognizing this token to turn it back into REF_STATUS_EXPECTING_REPORT has two advantages: 1. We now print exactly the same message in the human-readable (and machine-readable --porcelain) output for this situation whether the transport went through a helper (e.g., http) or not (e.g., ssh). 2. If any code in the helper really cares about distinguishing EXPECT_REPORT from more generic error conditions, it could now do so. I didn't find any, so this is mostly future-proofing. So this is mostly cosmetic for now, but it seems like the least-surprising thing for the transport-helper code to be doing.

2021-10-18send-pack: complain about "expecting report" with --helper-statusLibravatar Jeff King4-0/+27
When pushing to a server which erroneously omits the final ref-status report, the client side should complain about the refs for which we didn't receive the status (because we can't just assume they were updated). This works over most transports like ssh, but for http we'll print a very misleading "Everything up-to-date". It works for ssh because send-pack internally sets the status of each ref to REF_STATUS_EXPECTING_REPORT, and then if the server doesn't tell us about a particular ref, it will stay at that value. When we print the final status table, we'll see that we're still on EXPECTING_REPORT and complain then. But for http, we go through remote-curl, which invokes send-pack with "--stateless-rpc --helper-status". The latter option causes send-pack to return a machine-readable list of ref statuses to the remote helper. But ever since its inception in de1a2fdd38 (Smart push over HTTP: client side, 2009-10-30), the send-pack code has simply omitted mention of any ref which ended up in EXPECTING_REPORT. In the remote helper, we then take the absence of any status report from send-pack to mean that the ref was not even something we tried to send, and thus it prints "Everything up-to-date". Fortunately it does detect the eventual non-zero exit from send-pack, and propagates that in its own non-zero exit code. So at least a careful script invoking "git push" would notice the failure. But sending the misleading message on stderr is certainly confusing for humans (not to mention the machine-readable "push --porcelain" output, though again, any careful script should be checking the exit code from push, too). Nobody seems to have noticed because the server in this instance has to be misbehaving: it has promised to support the ref-status capability (otherwise the client will not set EXPECTING_REPORT at all), but didn't send us any. If the connection were simply cut, then send-pack would complain about getting EOF while trying to read the status. But if the server actually sends a flush packet (i.e., saying "now you have all of the ref statuses" without actually sending any), then the client ends up in this confused situation. The fix is simple: we should return an error message from "send-pack --helper-status", just like we would for any other error per-ref error condition (in the test I included, the server simply omits all ref status responses, but a more insidious version of this would skip only some of them).

2021-10-15tests: stop using top-level "README" and "COPYING" filesLibravatar Ævar Arnfjörð Bjarmason4-14/+19
In 459b8d22e54 (tests: do not borrow from COPYING and README from the real source, 2015-02-15) tests that used "lib-diff.sh" (called "diff-lib.sh" then) were made to stop relying on the top-level COPYING file, but we still had other tests that referenced it. Let's move them over to use the "COPYING_test_data" utility function introduced in the preceding commit, and in the case of the one test that needed the "README" file use a ROT 13 version of that "COPYING" test data. That test added in afd222967c6 (Extend testing git-mv for renaming of subdirectories, 2006-07-26) just needs more test data that's not the same as the "COPYING" test data, so a ROT 13 version will do.

2021-10-15"lib-diff" tests: make "README" and "COPYING" test data smallerLibravatar Ævar Arnfjörð Bjarmason10-419/+34
Follow-up the change in 459b8d22e54 (tests: do not borrow from COPYING and README from the real source, 2015-02-15) by not shipping a full copy of older versions of the top-level "COPYING" and "README" files. The tests that use them just need the small blurb at the top of "COPYING" as test data, or mock data that's dissimilar. Let's provide that with a "COPYING_test_data" function instead. We're not replacing this with some other generic test data (e.g. "lorum ipsum") because these tests require test file header to be the old "COPYING" file. See e.g. "t4003-diff-rename-1.sh" which changes the file, and then does full "test_cmp" comparisons on the resulting "git diff" output. This change only changes tests that used the "lib-diff.sh" library, but splits up what they need into a new "lib-diff-data.sh". A subsequent commit will change related tests that were missed in 459b8d22e54. For the test in "t4008-diff-break-rewrite.sh" the "README" file can go away in favor of echoing the line "some dissimilar content" to a file in the one test that needed it. The point of that test is to start with files "A" and "B", and then have A be more similar to the state of "B" than to its old version (by copying over the content from the "COPYING" file). Just comparing the pre-image of "some dissimilar content" and later a munged version of the "COPYING" output serves that purpose. While we're at it get rid of a stray "echo $tree" debugging line added in 15d061b435a ([PATCH] Fix the way diffcore-rename records unremoved source., 2005-05-27), and stop calling "hash-object" to get the hash of an object we've just added to the index.

2021-10-15test-lib.sh: try to re-chmod & retry on failed trash removalLibravatar Ævar Arnfjörð Bjarmason1-1/+13
Try to re-chmod the trash directory on startup if we fail to "rm -rf" it. This fixes problems where the test leaves the trash directory behind in a bad permission state for whatever reason. This fixes an interaction between [1] where t0004-unwritable.sh was made to use "test_when_finished" for cleanup, and [2] which added the "--immediate" mode. If a test in this file failed when running with "--immediate" we wouldn't run the "test_when_finished" block, which re-chmods the ".git/objects" directory (see [1]). This can be demonstrated as e.g. (output snipped for less verbosity): $ ./t0004-unwritable.sh --run=3 --immediate ok 1 # skip setup (--run) ok 2 # skip write-tree should notice unwritable repository (--run) not ok 3 - commit should notice unwritable repository [...] $ ./t0004-unwritable.sh --run=3 --immediate rm: cannot remove '[...]/trash directory.t0004-unwritable/.git/objects/info': Permission denied FATAL: Cannot prepare test area [...] Instead of some version of reverting [1] let's make the test-lib.sh resilient to this edge-case, it will happen due to [1], but also e.g. if the relevant "test-lib.sh" process is kill -9'd during the test run. We should try harder to recover in this case. If we fail to remove the test directory let's retry after (re-)chmod-ing it. This doesn't need to be guarded by something that's equivalent to "POSIXPERM" since if we don't support "chmod" we were about to fail anyway. Let's also discard any error output from (a possibly nonexisting) "chmod", we'll fail on the subsequent "rm -rf" anyway, likewise for the first "rm -rf" invocation, we don't want to get the "cannot remove" output if we can get around it with the "chmod", but we do want any error output from the second "rm -rf", in case that doesn't fix the issue. The lack of &&-chaining between the "chmod" and "rm -rf" is intentional, if we fail the first "rm -rf", can't chmod, but then succeed the second time around that's what we were hoping for. We just want to nuke the directory, not carry forward every possible error code or error message. 1. dbda967684d (t0004 (unwritable files): simplify error handling, 2010-09-06) 2. b586744a864 (test: skip clean-up when running under --immediate mode, 2011-06-27) Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-10-14test-lib.sh: use "Bail out!" syntax on bad SANITIZE=leak useLibravatar Ævar Arnfjörð Bjarmason1-4/+14
Improve the "GIT_TEST_PASSING_SANITIZE_LEAK=true" test mode added in 956d2e4639b (tests: add a test mode for SANITIZE=leak, run it in CI, 2021-09-23) to use a TAP "Bail out!" message when exiting. This will cause the test run to exit immediately under a TAP consumer like "prove(1)". See 614fe015212 (test-lib: bail out when "-v" used under "prove", 2016-10-22) for the initial introduction of "Bail out!" to the --verbose being amended here. Before this compiling with "SANITIZE=" and running the tests with "prove(1)" would cause all the tests to be run to the end (output trimmed for fewer columns): $ GIT_TEST_PASSING_SANITIZE_LEAK=true make rm -f -r 'test-results' *** prove *** t0000-basic.sh ......... Dubious, test returned 1 (wstat 256, 0x100) No subtests run t0001-init.sh .......... Dubious, test returned 1 (wstat 256, 0x100) No subtests run [...output where we list every single t[0-9]*.sh file as failing snipped] Whereas now we'll fail early, like this ("->" line wrapping added): $ GIT_TEST_PASSING_SANITIZE_LEAK=true make [...] t0000-basic.sh ..................................... Bailout called. Further testing stopped: -> GIT_TEST_PASSING_SANITIZE_LEAK=true has no effect except when compiled with SANITIZE=leak FAILED--Further testing stopped: GIT_TEST_PASSING_SANITIZE_LEAK=true has no effect except -> when compiled with SANITIZE=leak make: *** [Makefile:53: prove] Error 1 This change also adds a red color to the "Bailout called" line, as we're now using "say_color error". That improves existing output in the case of e.g.: $ prove -j8 t[0-9]*.sh :: -v Bailout called. Further testing stopped: verbose mode forbidden under TAP harness; try --verbose-log FAILED--Further testing stopped: verbose mode forbidden under TAP harness; try --verbose-log We don't need to have a "Bail out! " prefix when we're not running under a TAP consumer (i.e. if test -n "$HARNESS_ACTIVE"), but let's not make the output conditional on that. Showing it under e.g.: $ GIT_TEST_PASSING_SANITIZE_LEAK=true ./t0095-bloom.sh Bail out! GIT_TEST_PASSING_SANITIZE_LEAK=true has no effect except when compiled with SANITIZE=leak Doesn't harm anything, and I don't think the (small) complexity of only adding this if we're under "$HARNESS_ACTIVE" is worth it.

2021-10-12leak tests: mark some misc tests as passing with SANITIZE=leakLibravatar Ævar Arnfjörð Bjarmason10-0/+12
Mark some tests that match "*{mktree,commit,diff,grep,rm,merge,hunk}*" 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). These were picked because we still have a lot of failures in adjacent areas, and we didn't have much if any coverage of e.g. grep and diff before this change, we could still whitelist a lot more tests, but let's stop for now.
