2019-04-01commit-graph verify: detect inability to read the graphLibravatar Ævar Arnfjörð Bjarmason1-0/+6
Change "commit-graph verify" to error on open() failures other than ENOENT. As noted in the third paragraph of 283e68c72f ("commit-graph: add 'verify' subcommand", 2018-06-27) and the test it added it's intentional that "commit-graph verify" doesn't error out when the file doesn't exist. But let's not be overly promiscuous in what we accept. If we can't read the file for other reasons, e.g. permission errors, bad file descriptor etc. we'd like to report an error to the user.

2019-04-01commit-graph: don't early exit(1) on e.g. "git status"Libravatar Ævar Arnfjörð Bjarmason1-1/+1
Make the commit-graph loading code work as a library that returns an error code instead of calling exit(1) when the commit-graph is corrupt. This means that e.g. "status" will now report commit-graph corruption as an "error: [...]" at the top of its output, but then proceed to work normally. This required splitting up the load_commit_graph_one() function so that the code that deals with open()-ing and stat()-ing the graph can now be called independently as open_commit_graph(). This is needed because "commit-graph verify" where the graph doesn't exist isn't an error. See the third paragraph in 283e68c72f ("commit-graph: add 'verify' subcommand", 2018-06-27). There's a bug in that logic where we conflate the intended ENOENT with other errno values (e.g. EACCES), but this change doesn't address that. That'll be addressed in a follow-up change. I'm then splitting most of the logic out of load_commit_graph_one() into load_commit_graph_one_fd_st(), which allows for providing an existing file descriptor and stat information to the loading code. This isn't strictly needed, but it would be redundant and confusing to open() and stat() the file twice for some of the codepaths, this allows for calling open_commit_graph() followed by load_commit_graph_one_fd_st(). The "graph_file" still needs to be passed to that function for the the "graph file %s is too small" error message. This leaves load_commit_graph_one() unused by everything except the internal prepare_commit_graph_one() function, so let's mark it as "static". If someone needs it in the future we can remove the "static" attribute. I could also rewrite its sole remaining user ("prepare_commit_graph_one()") to use load_commit_graph_one_fd_st() instead, but let's leave it at this.

2019-04-01commit-graph: fix segfault on e.g. "git status"Libravatar Ævar Arnfjörð Bjarmason1-1/+2
When core.commitGraph=true is set, various common commands now consult the commit graph. Because the commit-graph code is very trusting of its input data, it's possibly to construct a graph that'll cause an immediate segfault on e.g. "status" (and e.g. "log", "blame", ...). In some other cases where git immediately exits with a cryptic error about the graph being broken. The root cause of this is that while the "commit-graph verify" sub-command exhaustively verifies the graph, other users of the graph simply trust the graph, and will e.g. deference data found at certain offsets as pointers, causing segfaults. This change does the bare minimum to ensure that we don't segfault in the common fill_commit_in_graph() codepath called by e.g. setup_revisions(), to do this instrument the "commit-graph verify" tests to always check if "status" would subsequently segfault. This fixes the following tests which would previously segfault: not ok 50 - detect low chunk count not ok 51 - detect missing OID fanout chunk not ok 52 - detect missing OID lookup chunk not ok 53 - detect missing commit data chunk Those happened because with the commit-graph enabled setup_revisions() would eventually call fill_commit_in_graph(), where e.g. g->chunk_commit_data is used early as an offset (and will be 0x0). With this change we get far enough to detect that the graph is broken, and show an error instead. E.g.: $ git status; echo $? error: commit-graph is missing the Commit Data chunk 1 That also sucks, we should *warn* and not hard-fail "status" just because the commit-graph is corrupt, but fixing is left to a follow-up change. A side-effect of changing the reporting from graph_report() to error() is that we now have an "error: " prefix for these even for "commit-graph verify". Pseudo-diff before/after: $ git commit-graph verify -commit-graph is missing the Commit Data chunk +error: commit-graph is missing the Commit Data chunk Changing that is OK. Various errors it emits now early on are prefixed with "error: ", moving these over and changing the output doesn't break anything.

Split up the corrupt_graph_and_verify() function added in d9b9f8a6fd ("commit-graph: verify catches corrupt signature", 2018-06-27) into its logical components of setting up the test itself, doing the corruption in a particular way with "dd", and then finally testing that stderr is what we expect. This allows for re-using everything except the now slimmer corrupt_graph_and_verify() to corrupt the graph in a way that doesn't involve inserting a given byte sequence at a given position, e.g. truncating it entirely to a custom value.

Some expected failures of git-http-backend leaves running its children (receive-pack or upload-pack) which still hold opened descriptors to act.err and with some probability they live long enough to write there their failure messages after next test has already truncated the files. This causes occasional failures of the test script. Avoid the issue by using separated output and error file for each test, apprending the test number to their name.

2019-02-19tests: teach the test-tool to generate NUL bytes and use itLibravatar Johannes Schindelin4-7/+24
In cc95bc2025 (t5562: replace /dev/zero with a pipe from generate_zero_bytes, 2019-02-09), we replaced usage of /dev/zero (which is not available on NonStop, apparently) by a Perl script snippet to generate NUL bytes. Sadly, it does not seem to work on NonStop, as t5562 reportedly hangs. Worse, this also hangs in the Ubuntu 16.04 agents of the CI builds on Azure Pipelines: for some reason, the Perl script snippet that is run via `generate_zero_bytes` in t5562's 'CONTENT_LENGTH overflow ssite_t' test case tries to write out an infinite amount of NUL bytes unless a broken pipe is encountered, that snippet never encounters the broken pipe, and keeps going until the build times out. Oddly enough, this does not reproduce on the Windows and macOS agents, nor in a local Ubuntu 18.04. This developer tried for a day to figure out the exact circumstances under which this hang happens, to no avail, the details remain a mystery. In the end, though, what counts is that this here change incidentally fixes that hang (maybe also on NonStop?). Even more positively, it gets rid of yet another unnecessary Perl invocation.

It was reported [1] that NonStop platform does not have /dev/zero. The test uses /dev/zero as a dummy input. Passing case (http-backed failed because of too big input size) should not be reading anything from it. If http-backend would erroneously try to read any data returning EOF probably would be even safer than providing some meaningless data. Replace /dev/zero with /dev/null to avoid issues with platforms which do not have /dev/zero.

2019-02-11utf8: handle systems that don't write BOM for UTF-16Libravatar brian m. carlson1-5/+29
When serializing UTF-16 (and UTF-32), there are three possible ways to write the stream. One can write the data with a BOM in either big-endian or little-endian format, or one can write the data without a BOM in big-endian format. Most systems' iconv implementations choose to write it with a BOM in some endianness, since this is the most foolproof, and it is resistant to misinterpretation on Windows, where UTF-16 and the little-endian serialization are very common. For compatibility with Windows and to avoid accidental misuse there, Git always wants to write UTF-16 with a BOM, and will refuse to read UTF-16 without it. However, musl's iconv implementation writes UTF-16 without a BOM, relying on the user to interpret it as big-endian. This causes t0028 and the related functionality to fail, since Git won't read the file without a BOM. Add a Makefile and #define knob, ICONV_OMITS_BOM, that can be set if the iconv implementation has this behavior. When set, Git will write a BOM manually for UTF-16 and UTF-32 and then force the data to be written in UTF-16BE or UTF-32BE. We choose big-endian behavior here because the tests use the raw "UTF-16" encoding, which will be big-endian when the implementation requires this knob to be set. Update the tests to detect this case and write test data with an added BOM if necessary. Always write the BOM in the tests in big-endian format, since all iconv implementations that omit a BOM must use big-endian serialization according to the Unicode standard. Preserve the existing behavior for systems which do not have this knob enabled, since they may use optimized implementations, including defaulting to the native endianness, which may improve performance.

The setup code uses octal values with printf to generate a BOM for UTF-16/32 BE/LE. It specifically uses '\777' to emit a 0xff byte. This relies on the fact that most shells truncate the value above 0o377. Ash however interprets '\777' as '\77' + a literal '7', resulting in an invalid BOM.

Use a '!' character to start a non-matching pattern bracket expression, as specified by POSIX in Shell Command Language section 2.13.1 Patterns Matching a Single Character [1]. I used '^' instead in three places in the previous three commits, to verify that the arguments of the '--stress=' and '--stress-limit=' options and the values of various '*_PORT' environment variables are valid numbers. With certain shells, at least with dash (upstream and in Ubuntu 14.04) and mksh, this led to various undesired behaviors: # error message in case of a valid number $ ~/src/dash/src/dash ./t3903-stash.sh --stress=8 error: --stress=<N> requires the number of jobs to run # not the expected error message $ ~/src/dash/src/dash ./t3903-stash.sh --stress=foo ./t3903-stash.sh: 238: test: Illegal number: foo # no error message at all?! $ mksh ./t3903-stash.sh --stress=foo $ echo $? 0 Some other shells, e.g. Bash (even in posix mode), ksh, dash in Ubuntu 16.04 or later, are apparently happy to accept '^' just as well.

2019-02-08test-lib: make '--stress' more bisect-friendlyLibravatar SZEDER Gábor2-2/+21
Let's suppose that a test somehow becomes flaky between 'master' and 'pu', and tends to fail within the first 50 repetitions when run with '--stress'. In such a case we could use 'git bisect' to find the culprit: if the test script fails with '--stress', then the commit is definitely bad, but if it survives, say, 300 repetitions, then we could consider it good with reasonable confidence. Unfortunately, all this could only be done manually, because '--stress' would run the test script repeatedly for all eternity on a good commit, and it would exit with success even when it found a failure on a bad commit. So let's make '--stress' usable with 'git bisect run': - Make it exit with failure if a failure is found. - Add the '--stress-limit=<N>' option to repeat the test script at most N times in each of the parallel jobs, and exit with success when the limit is reached. And then we could simply run something like: $ git bisect start origin/pu master $ git bisect run sh -c 'make && cd t && ./t1234-foo.sh --stress --stress-limit=300' Sure, as a brand new feature it won't be any useful right now, but in a release or three most cooking topics will already contain this, so we could automatically bisect at least newly introduced flakiness.

This daemon may stay running after the test and cache file descriptors for the trash directories, even after the trash directory is removed. This leads to ENOENT errors when attempting to create files if tests are run multiple times.

"git pack-objects" learned another algorithm to compute the set of objects to send, that trades the resulting packfile off to save traversal cost to favor small pushes. * ds/push-sparse-tree-walk: pack-objects: create GIT_TEST_PACK_SPARSE pack-objects: create pack.useSparse setting revision: implement sparse algorithm list-objects: consume sparse tree walk revision: add mark_tree_uninteresting_sparse
2019-02-06Merge branch 'tb/test-lint-sed-options'Libravatar Junio C Hamano1-1/+1
The test lint learned to catch non-portable "sed" options. * tb/test-lint-sed-options: test-lint: only use only sed [-n] [-e command] [-f command_file]
2019-02-06Merge branch 'lt/date-human'Libravatar Junio C Hamano2-3/+32
A new date format "--date=human" that morphs its output depending on how far the time is from the current time has been introduced. "--date=auto" can be used to use this new format when the output is going to the pager or to the terminal and otherwise the default format. * lt/date-human: Add `human` date format tests. Add `human` format to test-tool Add 'human' date format documentation Replace the proposed 'auto' mode with 'auto:' Add 'human' date format

2019-02-06git-p4: remove ticket expiry testLibravatar Luke Diamand1-27/+0
The git-p4 login ticket expiry test causes unreliable test runs. Since the handling of ticket expiry in git-p4 is far from polished anyway, let's remove it for now. A better way to actually run the test is to create a python "fake" version of "p4" which returns whatever expiry results the test requires. Ideally git-p4 would look at the expiry time before starting any long operations, and cleanup gracefully if there is not enough time left. But that's quite hard to do.
