2021-05-13t: avoid sed-based chain-linting in some expensive casesLibravatar Jeff King1-1/+6
Commit 878f988350 (t/test-lib: teach --chain-lint to detect broken &&-chains in subshells, 2018-07-11) introduced additional chain-lint tests which add an extra "sed" pipeline to each test we run. This has a measurable impact on runtime. Here are timings with and without a new environment variable (added by this patch) that lets you disable just the additional sed-based chain-lint tests: Benchmark #1: GIT_TEST_CHAIN_LINT_HARDER=1 make test Time (mean ± σ): 64.202 s ± 1.030 s [User: 622.469 s, System: 301.402 s] Range (min … max): 61.571 s … 65.662 s 10 runs Benchmark #2: GIT_TEST_CHAIN_LINT_HARDER=0 make test Time (mean ± σ): 57.591 s ± 0.333 s [User: 529.368 s, System: 270.618 s] Range (min … max): 57.143 s … 58.309 s 10 runs Summary 'GIT_TEST_CHAIN_LINT_HARDER=0 make test' ran 1.11 ± 0.02 times faster than 'GIT_TEST_CHAIN_LINT_HARDER=1 make test' Of course those extra lint checks are doing something useful, so paying a few extra seconds (at least on Linux) isn't so bad (though note the CPU time; we're bounded in our parallel run here by the slowest test, so it really is ~120s of CPU improvement). But we can observe that there are some test scripts where they produce a much stronger effect, and provide less value. In t0027 and t3070 we run a very large number of small tests, all driven by a series of functions/loops which are filling in the test bodies. There we get much less bang for our buck in terms of bug-finding versus CPU cost. This patch introduces a mechanism for controlling when those extra lint checks are run, at two levels: - a user can ask to disable or to force-enable the checks by setting GIT_TEST_CHAIN_LINT_HARDER - if the user hasn't specified a preference, individual scripts can disable the checks by setting GIT_TEST_CHAIN_LINT_HARDER_DEFAULT; scripts which don't set that get the current behavior of enabling them. In addition, this patch flips the default for t0027 and t3070's mass-generated sections to disable the extra checks. Here are the timing results for t0027: Benchmark #1: GIT_TEST_CHAIN_LINT_HARDER=1 ./t0027-auto-crlf.sh Time (mean ± σ): 17.078 s ± 0.848 s [User: 14.878 s, System: 7.075 s] Range (min … max): 15.952 s … 18.421 s 10 runs Benchmark #2: GIT_TEST_CHAIN_LINT_HARDER=0 ./t0027-auto-crlf.sh Time (mean ± σ): 9.063 s ± 0.759 s [User: 7.890 s, System: 3.362 s] Range (min … max): 7.747 s … 10.619 s 10 runs Benchmark #3: ./t0027-auto-crlf.sh Time (mean ± σ): 9.186 s ± 0.881 s [User: 7.957 s, System: 3.427 s] Range (min … max): 7.796 s … 10.498 s 10 runs Summary 'GIT_TEST_CHAIN_LINT_HARDER=0 ./t0027-auto-crlf.sh' ran 1.01 ± 0.13 times faster than './t0027-auto-crlf.sh' 1.88 ± 0.18 times faster than 'GIT_TEST_CHAIN_LINT_HARDER=1 ./t0027-auto-crlf.sh' We can see that disabling the checks for the whole script buys us an almost 2x speedup. But the new default behavior, disabling them only for the mass-generated part, gets us most of that speedup (but still leaves the checks on for further manual tests people might write). As a side note, I'd caution about comparing runtimes and CPU seconds between this timing and the earlier "make test" one. In "make test", we're running a lot of scripts in parallel, so the CPU is throttling down (and thus a CPU second saved here would count for more during a parallel run; the same work takes more CPU seconds there). We get similar results for t3070: Benchmark #1: GIT_TEST_CHAIN_LINT_HARDER=1 ./t3070-wildmatch.sh Time (mean ± σ): 20.054 s ± 3.967 s [User: 16.003 s, System: 8.286 s] Range (min … max): 11.891 s … 23.671 s 10 runs Benchmark #2: GIT_TEST_CHAIN_LINT_HARDER=0 ./t3070-wildmatch.sh Time (mean ± σ): 12.399 s ± 2.256 s [User: 7.542 s, System: 5.342 s] Range (min … max): 9.606 s … 15.727 s 10 runs Benchmark #3: ./t3070-wildmatch.sh Time (mean ± σ): 10.726 s ± 3.476 s [User: 6.790 s, System: 4.365 s] Range (min … max): 5.444 s … 15.376 s 10 runs Summary './t3070-wildmatch.sh' ran 1.16 ± 0.43 times faster than 'GIT_TEST_CHAIN_LINT_HARDER=0 ./t3070-wildmatch.sh' 1.87 ± 0.71 times faster than 'GIT_TEST_CHAIN_LINT_HARDER=1 ./t3070-wildmatch.sh' Again, we get almost a 2x speedup disabling these. In this case, there are no tests not covered by the script's "default to disable" behavior, so the second two benchmarks should be the same (and while they do differ, you can see the variance is quite high but they're within one standard deviation). So it seems like for these two scripts, at least, disabling the extra checks is a reasonable tradeoff. Sadly, the overall runtime of "make test" on my system doesn't get much faster. But that's because we're mostly limited by the cost of the single biggest test. Here are the top-5 tests by wall-clock time from a parallel run, before my patch: 57.9192368984222 t9001-send-email.sh 45.6329638957977 t0027-auto-crlf.sh 32.5278220176697 t3070-wildmatch.sh 22.2701289653778 t7610-mergetool.sh 20.8635759353638 t1701-racy-split-index.sh And after: 57.1476998329163 t9001-send-email.sh 33.776211977005 t0027-auto-crlf.sh 21.3116669654846 t7610-mergetool.sh 20.7748689651489 t1701-racy-split-index.sh 19.6957249641418 t7112-reset-submodule.sh We dropped 12s from t0027, and t3070 dropped off our list entirely at around 16s. In both cases we're bound by t9001, but its slowness is due to the actual tests, so we'll have to deal with it in a different way. But this reduces overall CPU, and means that dealing with t9001 (by improving the speed of send-email or splitting it apart) will let us reduce our overall runtime even on multi-core machines.

2020-11-19t[01]*: adjust the references to the default branch name "main"Libravatar Johannes Schindelin1-2/+2
Carefully excluding t1309, which sees independent development elsewhere at the time of writing, we transition above-mentioned tests to the default branch name `main`. This trick was performed via $ (cd t && sed -i -e 's/master/main/g' -e 's/MASTER/MAIN/g' \ -e 's/Master/Main/g' -e 's/naster/nain/g' -- t[01]*.sh && git checkout HEAD -- t1309\*) Note that t5533 contains a variation of the name `master` (`naster`) that we rename here, too. This allows us to define `GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main` for those tests.

2019-07-01t0027: make hash size independentLibravatar brian m. carlson1-2/+4
Several parts of this test generate files that have specific hard-coded object IDs in them. We don't really care about what the object ID in question is, so we turn them all to zeros. However, because some of these values are fixed and some are generated, they can be of different lengths, which causes problems when running with SHA-256. Furthermore, some assertions in this test use only fixed object IDs and some use both fixed and generated ones, so converting only the expected results fixes some tests while breaking others. Convert both actual and expected object IDs to the all-zeros object ID of the appropriate length to ensure that the test passes when using SHA-256. The astute observer will notice that both tr and sed are used here. Converting the tr call to a sed y/// command looks logical at first, but it isn't possible because POSIX doesn't allow escapes in y/// commands other than "\\" and "\n".

2017-11-27convert: tighten the safe autocrlf handlingLibravatar Torsten Bögershausen1-5/+71
When a text file had been commited with CRLF and the file is commited again, the CRLF are kept if .gitattributs has "text=auto". This is done by analyzing the content of the blob stored in the index: If a '\r' is found, Git assumes that the blob was commited with CRLF. The simple search for a '\r' does not always work as expected: A file is encoded in UTF-16 with CRLF and commited. Git treats it as binary. Now the content is converted into UTF-8. At the next commit Git treats the file as text, the CRLF should be converted into LF, but isn't. Replace has_cr_in_index() with has_crlf_in_index(). When no '\r' is found, 0 is returned directly, this is the most common case. If a '\r' is found, the content is analyzed more deeply.

2017-11-06Merge branch 'ex/deprecate-empty-pathspec-as-match-all'Libravatar Junio C Hamano1-1/+1
The final step to make an empty string as a pathspec element illegal. We started this by first deprecating and warning a pathspec that has such an element in 2.11 (Nov 2016). Hopefully we can merge this down to the 'master' by the end of the year? A deprecation warning period that is about 1 year does not sound too bad. * ex/deprecate-empty-pathspec-as-match-all: pathspec: die on empty strings as pathspec t0027: do not use an empty string as a pathspec element
2017-06-23t0027: do not use an empty string as a pathspec elementLibravatar Junio C Hamano1-1/+1
In an upcoming update, we will finally make an empty string illegal as an element in a pathspec; it traditionally meant the same as ".", i.e. include everything, so update this test that passes "" to pass a dot instead. At this point in the test sequence, there is no modified path that need to be further added before committing; the working tree is empty except for .gitattributes which was just added to the index. So we could instead pass no pathspec, but this is a conversion more faithful to the original. Signed-off-by: Junio C Hamano <gitster@pobox.com>

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>
2017-05-10t0027: tests are not expensive; remove t0025Libravatar Torsten Bögershausen1-6/+0
The purpose of t0027 is to test all CRLF related conversions at "git checkout" and "git add". Running t0027 under Git for Windows takes 3-4 minutes, so the whole script had been marked as "EXPENSIVE". However, the "Git for Windows" fork overrides this since 2014: "t0027 is marked expensive, but really, for MinGW we want to run these tests always." The test seems not to be expensive on other platforms at all: it takes less than 14 seconds under Linux, and 63 seconds under Mac Os X, and this is more or less the same with a SSD or a spinning disk. So let's drop the "EXPENSIVE" prereq. While at it, retire t0025; recent "stress" tests show that t0025 is flaky, reported by Lars Schneider <larsxschneider@gmail.com>, but all tests in t0025 are covered by t0027 already.

2016-08-14convert: Correct NNO tests and missing `LF will be replaced by CRLF`Libravatar Torsten Bögershausen1-3/+3
When a non-reversible CRLF conversion is done in "git add", a warning is printed on stderr (or Git dies, depending on checksafe) The function commit_chk_wrnNNO() in t0027 was written to test this, but did the wrong thing: Instead of looking at the warning from "git add", it looked at the warning from "git commit". This is racy because "git commit" may not have to do CRLF conversion at all if it can use the sha1 value from the index (which depends on whether "add" and "commit" run in a single second). Correct t0027 and replace the commit for each and every file with a commit of all files in one go. The function commit_chk_wrnNNO() should be renamed in a separate commit. Now that t0027 does the right thing, it detects a bug in covert.c: This sequence should generate the warning `LF will be replaced by CRLF`, but does not: $ git init $ git config core.autocrlf false $ printf "Line\r\n" >file $ git add file $ git commit -m "commit with CRLF" $ git config core.autocrlf true $ printf "Line\n" >file $ git add file "git add" calls crlf_to_git() in convert.c, which calls check_safe_crlf(). When has_cr_in_index(path) is true, crlf_to_git() returns too early and check_safe_crlf() is not called at all. Factor out the code which determines if "git checkout" converts LF->CRLF into will_convert_lf_to_crlf(). Update the logic around check_safe_crlf() and "simulate" the possible LF->CRLF conversion at "git checkout" with help of will_convert_lf_to_crlf().

Add test cases for core.eol "native" and "" (unset). (MINGW uses CRLF, all other systems LF as native line endings) Add test cases for the attributes "eol=lf" and "eol=crlf" Other minor changes: - Use the more portable 'tr' instead of 'od -c' to convert '\n' into 'Q' and '\0' into 'N' - Style fixes for shell functions according to the coding guide lines - Replace "txtbin" with "attr" Signed-off-by: Torsten Bögershausen <tboegi@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-07-08t0027: combinations of core.autocrlf, core.eol and textLibravatar Torsten Bögershausen1-0/+265
Historically there are 3 different parameters controlling how line endings are handled by Git: - core.autocrlf - core.eol - the "text" attribute in .gitattributes There are different types of content: - (1) Files with only LF - (2) Files with only CRLF - (3) Files with mixed LF and CRLF - (4) Files with LF and/or CRLF with CR not followed by LF - (5) Files which are binary (e.g. have NUL bytes) Recently the question came up, how files with mixed EOLs are handled by Git (and libgit2) when they are checked out and core.autocrlf=true. See http://git.661346.n2.nabble.com/The-different-EOL-behavior-between-libgit2-based-software-and-official-Git-td7613670.html#a7613801 Add the EXPENSIVE t0027-auto-crlf.sh to test all combination of files and parameters for both "git add/commit" and "git checkout".
