2018-11-02tests: optionally skip `git rebase -p` testsLibravatar Johannes Schindelin1-0/+4
The `--preserve-merges` mode of the `rebase` command is slated to be deprecated soon, as the more powerful `--rebase-merges` mode is available now, and the latter was designed with the express intent to address the shortcomings of `--preserve-merges`' design (e.g. the inability to reorder commits in an interactive rebase). As such, we will eventually even remove the `--preserve-merges` support, and along with it, its tests. In preparation for this, and also to allow the Windows phase of our automated tests to save some well-needed time when running the test suite, this commit introduces a new prerequisite REBASE_P, which can be forced to being unmet by setting the environment variable `GIT_TEST_SKIP_REBASE_P` to any non-empty string.

2018-09-28t0000: do not get self-test disrupted by environment warningsLibravatar Junio C Hamano1-0/+8
The test framework test-lib.sh itself would want to give warnings and hints, e.g. when it sees a deprecated environment variable is in use that we want to encourage users to migrate to another variable. The self-test of test framework done in t0000 however do not expect to see these warnings and hints, so depending on the settings of environment variables, a running test may or may not produce these messages to the standard error output, breaking the expectations of self-test test framework does on itself. Here is what we see: $ TEST_GIT_INDEX_VERSION=4 sh t0000-basic.sh -i -v ... 'err' is not empty, it contains: warning: TEST_GIT_INDEX_VERSION is now GIT_TEST_INDEX_VERSION hint: set GIT_TEST_INDEX_VERSION too during the transition period not ok 5 - pretend we have a fully passing test suite The following quick attempt to work it around does not work, because some tests in t0000 do want to see expected errors from the test framework itself. t/t0000-basic.sh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/t/t0000-basic.sh b/t/t0000-basic.sh index 850f651e4e..88c6ed4696 100755 --- a/t/t0000-basic.sh +++ b/t/t0000-basic.sh @@ -88,7 +88,7 @@ _run_sub_test_lib_test_common () { ' # Point to the t/test-lib.sh, which isn't in ../ as usual - .

2018-09-17Merge branch 'nd/unpack-trees-with-cache-tree'Libravatar Junio C Hamano1-0/+6
The unpack_trees() API used in checking out a branch and merging walks one or more trees along with the index. When the cache-tree in the index tells us that we are walking a tree whose flattened contents is known (i.e. matches a span in the index), as linearly scanning a span in the index is much more efficient than having to open tree objects recursively and listing their entries, the walk can be optimized, which is done in this topic. * nd/unpack-trees-with-cache-tree: Document update for nd/unpack-trees-with-cache-tree cache-tree: verify valid cache-tree in the test suite unpack-trees: add missing cache invalidation unpack-trees: reuse (still valid) cache-tree from src_index unpack-trees: reduce malloc in cache-tree walk unpack-trees: optimize walking same trees with cache-tree unpack-trees: add performance tracing trace.h: support nested performance tracing
2018-08-27tests: fix and add lint for non-portable head -c NLibravatar Ævar Arnfjörð Bjarmason1-2/+2
The "head -c BYTES" option is non-portable (not in POSIX[1]). Change such invocations to use the test_copy_bytes wrapper added in 48860819e8 ("t9300: factor out portable "head -c" replacement", 2016-06-30). This fixes a test added in 9d2e330b17 ("ewah_read_mmap: bounds-check mmap reads", 2018-06-14), which has been breaking t5310-pack-bitmaps.sh on OpenBSD since 2.18.0. The OpenBSD ports already have a similar workaround after their upgrade to 2.18.0[2]. I have not tested this on IRIX, but according to 4de0bbd898 ("t9300: use perl "head -c" clone in place of "dd bs=1 count=16000" kluge", 2010-12-13) this invocation would have broken things there too. Also, change a valgrind-specific codepath in test-lib.sh to use this wrapper. Given where valgrind runs I don't think this would ever become a portability issue in practice, but it's easier to just use the wrapper than introduce some exception for the "make test-lint" check being added here. 1. http://pubs.opengroup.org/onlinepubs/9699919799/utilities/head.html 2. https://github.com/openbsd/ports/commit/08d5d82eaefe5cf2f125ecc0c6a57df9cf91350c#diff-f7d3c4fabeed1691620d608f1534f5e5 Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-08-06t: factor out FUNNYNAMES as shared lazy prereqLibravatar William Chargin1-0/+14
A fair number of tests need to check that the filesystem supports file names including "funny" characters, like newline, tab, and double-quote. Jonathan Nieder suggested that this be extracted into a lazy prereq in the top-level `test-lib.sh`. This patch effects that change. The FUNNYNAMES prereq now uniformly requires support for newlines, tabs, and double-quotes in filenames. This very slightly decreases the power of some tests, which might have run previously on a system that supports (e.g.) newlines and tabs but not double-quotes, but now will not. This seems to me like an acceptable tradeoff for consistency. One test (`t/t9902-completion.sh`) defined FUNNYNAMES to further require the separators \034 through \037, the test for which was implemented using the Bash-specific $'\034' syntax. I've elected to leave this one as is, renaming it to FUNNIERNAMES. After this patch, `git grep 'test_\(set\|lazy\)_prereq.*FUNNYNAMES'` has only one result.

2018-07-17t/test-lib: teach --chain-lint to detect broken &&-chains in subshellsLibravatar Eric Sunshine1-1/+2
The --chain-lint option detects broken &&-chains by forcing the test to exit early (as the very first step) with a sentinel value. If that sentinel is the test's overall exit code, then the &&-chain is intact; if not, then the chain is broken. Unfortunately, this detection does not extend to &&-chains within subshells even when the subshell itself is properly linked into the outer &&-chain. Address this shortcoming by feeding the body of the test to a lightweight "linter" which can peer inside subshells and identify broken &&-chains by pure textual inspection. Although the linter does not actually parse shell scripts, it has enough knowledge of shell syntax to reliably deal with formatting style variations (as evolved over the years) and to avoid being fooled by non-shell content (such as inside here-docs and multi-line strings). It recognizes modern subshell formatting: statement1 && ( statement2 && statement3 ) && statement4 as well as old-style: statement1 && (statement2 && statement3) && statement4 Heuristics are employed to properly identify the extent of a subshell formatted in the old-style since a number of legitimate constructs may superficially appear to close the subshell even though they don't. For example, it understands that neither "x=$(command)" nor "case $x in *)" end a subshell, despite the ")" at the end of line. Due to limitations of the tool used ('sed') and its inherent line-by-line processing, only subshells one level deep are handled, as well as one-liner subshells one level below that. Subshells deeper than that or multi-line subshells at level two are passed through as-is, thus &&-chains in their bodies are not checked.

2018-05-14t/test-lib: add an SHA1 prerequisiteLibravatar brian m. carlson1-0/+7
There are some basic tests in our codebase that test that we get fixed SHA-1 values. These are valuable because they make sure that our SHA-1 implementation is free of bugs, but obviously these tests will fail with a different hash. There are also tests which intentionally produce objects that have collisions when truncated to a certain length to test our handling of these cases. These tests, too, will fail with a different hash. Add an SHA1 prerequisite to annotate both of these types of tests and disable them when we're using a different hash. In the future, we will create versions of these tests which handle both SHA-1 and NewHash.

On APFS, which appears to be the new default filesystem in Mac OS High Sierra, filenames are recorded as specified by the user. APFS continues to allow the user to access it via any name that normalizes to the same thing. This difference causes t0050-filesystem.sh to fail two tests.

Note that we can't mark the individual tests with the CURL prerequisite. They're in a shared t556x_common that uses the GET and POST functions as a level of indirection, and it's only our implementations of those functions in t5561 that requires curl. It's not a problem, though, as literally every test in the script would depend on the prerequisite anyway.

2017-12-11Makefile: replace perl/Makefile.PL with simple make rulesLibravatar Ævar Arnfjörð Bjarmason1-1/+1
Replace the perl/Makefile.PL and the fallback perl/Makefile used under NO_PERL_MAKEMAKER=NoThanks with a much simpler implementation heavily inspired by how the i18n infrastructure's build process works[1]. The reason for having the Makefile.PL in the first place is that it was initially[2] building a perl C binding to interface with libgit, this functionality, that was removed[3] before Git.pm ever made it to the master branch. We've since since started maintaining a fallback perl/Makefile, as MakeMaker wouldn't work on some platforms[4]. That's just the tip of the iceberg. We have the PM.stamp hack in the top-level Makefile[5] to detect whether we need to regenerate the perl/perl.mak, which I fixed just recently to deal with issues like the perl version changing from under us[6]. There is absolutely no reason for why this needs to be so complex anymore. All we're getting out of this elaborate Rube Goldberg machine was copying perl/* to perl/blib/* as we do a string-replacement on the *.pm files to hardcode @@LOCALEDIR@@ in the source, as well as pod2man-ing Git.pm & friends. So replace the whole thing with something that's pretty much a copy of how we generate po/build/**.mo from po/*.po, just with a small sed(1) command instead of msgfmt. As that's being done rename the files from *.pm to *.pmc just to indicate that they're generated (see "perldoc -f require"). While I'm at it, change the fallback for Error.pm from being something where we'll ship our own Error.pm if one doesn't exist at build time to one where we just use a Git::Error wrapper that'll always prefer the system-wide Error.pm, only falling back to our own copy if it really doesn't exist at runtime. It's now shipped as Git::FromCPAN::Error, making it easy to add other modules to Git::FromCPAN::* in the future if that's needed. Functional changes: * This will not always install into perl's idea of its global "installsitelib". This only potentially matters for packagers that need to expose Git.pm for non-git use, and as explained in the INSTALL file there's a trivial workaround. * The scripts themselves will 'use lib' the target directory, but if INSTLIBDIR is set it overrides it. It doesn't have to be this way, it could be set in addition to INSTLIBDIR, but my reading of [7] is that this is the desired behavior. * We don't build man pages for all of the perl modules as we used to, only Git(3pm). As discussed on-list[8] that we were building installed manpages for purely internal APIs like Git::I18N or private-Error.pm was always a bug anyway, and all the Git::SVN::* ones say they're internal APIs. There are apparently external users of Git.pm, but I don't expect there to be any of the others. As a side-effect of these general changes the perl documentation now only installed by install-{doc,man}, not a mere "install" as before. 1. 5e9637c629 ("i18n: add infrastructure for translating Git with gettext", 2011-11-18) 2. b1edc53d06 ("Introduce Git.pm (v4)", 2006-06-24) 3. 18b0fc1ce1 ("Git.pm: Kill Git.xs for now", 2006-09-23) 4. f848718a69 ("Make perl/ build procedure ActiveState friendly.", 2006-12-04) 5. ee9be06770 ("perl: detect new files in MakeMaker builds", 2012-07-27) 6. c59c4939c2 ("perl: regenerate perl.mak if perl -V changes", 2017-03-29) 7. 0386dd37b1 ("Makefile: add PERLLIB_EXTRA variable that adds to default perl path", 2013-11-15) 8. 87bmjjv1pu.fsf@evledraar.booking.com ("Re: [PATCH] Makefile: replace perl/Makefile.PL with simple make rules" Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-12-08t/Makefile: introduce TEST_SHELL_PATHLibravatar Jeff King1-1/+1
You may want to run the test suite with a different shell than you use to build Git. For instance, you may build with SHELL_PATH=/bin/sh (because it's faster, or it's what you expect to exist on systems where the build will be used) but want to run the test suite with bash (e.g., since that allows using "-x" reliably across the whole test suite). There's currently no good way to do this. You might think that doing two separate make invocations, like: make && make -C t SHELL_PATH=/bin/bash would work. And it _almost_ does. The second make will see our bash SHELL_PATH, and we'll use that to run the individual test scripts (or tell prove to use it to do so). So far so good. But this breaks down when "--tee" or "--verbose-log" is used. Those options cause the test script to actually re-exec itself using $SHELL_PATH. But wait, wouldn't our second make invocation have set SHELL_PATH correctly in the environment? Yes, but test-lib.sh sources GIT-BUILD-OPTIONS, which we built during the first "make". And that overrides the environment, giving us the original SHELL_PATH again. Let's introduce a new variable that lets you specify a specific shell to be run for the test scripts. Note that we have to touch both the main and t/ Makefiles, since we have to record it in GIT-BUILD-OPTIONS in one, and use it in the latter.

2017-12-08test-lib: make "-x" work with "--verbose-log"Libravatar Jeff King1-2/+8
The "-x" tracing option implies "--verbose". This is a problem when running under a TAP harness like "prove", where we need to use "--verbose-log" instead. Instead, let's handle this the same way we do for --valgrind, including the recent fix from 88c6e9d31c (test-lib: --valgrind should not override --verbose-log, 2017-09-05). Namely, let's enable --verbose only when we know there isn't a more specific verbosity option indicated. Note that we also have to tweak `want_trace` to turn it on (previously we just lumped $verbose_log in with $verbose, but now we don't necessarily auto-set the latter).

2017-12-08test-lib: silence "-x" cleanup under bashLibravatar Jeff King1-10/+24
When the test suite's "-x" option is used with bash, we end up seeing cleanup cruft in the output: $ bash t0001-init.sh -x [...] ++ diff -u expected actual + test_eval_ret_=0 + want_trace + test t = t + test t = t + set +x ok 42 - re-init from a linked worktree This ranges from mildly annoying (for a successful test) to downright confusing (when we say "last command exited with error", but it's really 5 commands back). We normally are able to suppress this cleanup. As the in-code comment explains, we can't convince the shell not to print it, but we can redirect its stderr elsewhere. But since d88785e424 (test-lib: set BASH_XTRACEFD automatically, 2016-05-11), that doesn't hold for bash. It sends the "set -x" output directly to descriptor 4, not to stderr. We can fix this by also redirecting descriptor 4, and paying close attention to which commands redirected and which are not (see the updated comment). Two alternatives I considered and rejected: - unsetting and setting BASH_XTRACEFD; doing so closes the descriptor, which we must avoid - we could keep everything in a single block as before, redirect 4>/dev/null there, but retain 5>&4 as a copy. And then selectively restore 4>&5 for commands which should be allowed to trace. This would work, but the descriptor swapping seems unnecessarily confusing.

2017-11-24test-lib: add LIBPCRE1 & LIBPCRE2 prerequisitesLibravatar Ævar Arnfjörð Bjarmason1-0/+2
Add LIBPCRE1 and LIBPCRE2 prerequisites which are true when git is compiled with USE_LIBPCRE1=YesPlease or USE_LIBPCRE2=YesPlease, respectively. The syntax of PCRE1 and PCRE2 isn't the same in all cases (see pcresyntax(3) and pcre2syntax(3)). If test are added that test for those they'll need to be guarded by these new prerequisites. The subsequent patch will make use of LIBPCRE2, so LIBPCRE1 isn't strictly needed for now, but let's add it for consistency and so that checking for it doesn't have to be done with the less obvious "PCRE, !LIBPCRE2", which while semantically the same is more confusing, and would lead to bugs if PCRE v3 is ever released as the tests would mean v1, not any non-v2 version.

2017-11-13t4201: make use of abbreviation in the test more robustLibravatar Charles Bailey1-3/+4
The test for '--abbrev' in t4201-shortlog.sh assumes that the commits generated in the test can always be uniquely abbreviated to 5 hex digits but this is not always the case. If you were unlucky and happened to run the test at (say) Thu Jun 22 03:04:49 2017 +0000, you would find that the first commit generated would collide with a tree object created later in the same test. This can be simulated in the version of t4201-shortlog.sh prior to this commit by setting GIT_COMMITTER_DATE and GIT_AUTHOR_DATE to 1498100689 after sourcing test-lib.sh. Change the test to test --abbrev=35 instead of --abbrev=5 to almost completely avoid the possibility of a partial collision and add a call to test_tick in the setup to make the test repeatable (the latter alone is sufficient to make it robust enough).

2017-09-15test-lib: don't use ulimit in test prerequisites on cygwinLibravatar Ramsay Jones1-2/+8
On cygwin (and MinGW), the 'ulimit' built-in bash command does not have the desired effect of limiting the resources of new processes, at least for the stack and file descriptors. However, it always returns success and leads to several test prerequisites being erroneously set to true. Add a check for cygwin and MinGW to the prerequisite expressions, using a 'test_have_prereq !MINGW,!CYGWIN' clause, to guard against using ulimit. This affects the prerequisite expressions for the ULIMIT_STACK_SIZE, CMDLINE_LIMIT and ULIMIT_FILE_DESCRIPTORS prerequisites.
