2014-06-04t5000, t5003: do not use test_cmp to compare binary filesLibravatar Stepan Kasal1-0/+6
test_cmp() is primarily meant to compare text files (and display the difference for debug purposes). Raw "cmp" is better suited to compare binary files (tar, zip, etc.). On MinGW, test_cmp is a shell function mingw_test_cmp that tries to read both files into environment, stripping CR characters (introduced in commit 4d715ac0). This function usually speeds things up, as fork is extremly slow on Windows. But no wonder that this function is extremely slow and sometimes even crashes when comparing large tar or zip files.

2014-02-24test-lib: allow setting the index format versionLibravatar Thomas Gummerer1-0/+5
Allow adding a TEST_GIT_INDEX_VERSION variable to config.mak to set the index version with which the test suite should be run. If it isn't set, the default version given in the source code is used (currently version 3). To avoid breakages with index versions other than [23], also set the index version under which t2104 is run to 3. This test only tests functionality specific to version 2 and 3 of the index file and would fail if the test suite is run with any other version.

2014-02-14tests: turn on network daemon tests by defaultLibravatar Jeff King1-0/+58
We do not run the httpd nor git-daemon tests by default, as they are rather heavyweight and require network access (albeit over localhost). However, it would be nice if more pepole ran them, for two reasons: 1. We would get more test coverage on more systems. 2. The point of the test suite is to find regressions. It is very easy to change some of the underlying code and break the httpd code without realizing you are even affecting it. Running the httpd tests helps find these problems sooner (ideally before the patches even hit the list). We still want to leave an "out", though, for people who really do not want to run them. For that reason, the GIT_TEST_HTTPD and GIT_TEST_GIT_DAEMON variables are now tri-state booleans (true/false/auto), so you can say GIT_TEST_HTTPD=false to turn the tests back off. To support those who want a stable single way to disable these tests across versions of Git before and after this change, an empty string explicitly set to these variables is also taken as "false", so the behaviour changes only for those who: a. did not express any preference by leaving these variables unset. They did not test these features before, but now they do; or b. did express that they want to test these features by setting GIT_TEST_FEATURE=false (or any equivalent other ways to tell "false" to Git, e.g. "0"), which has been a valid but funny way to say that they do want to test the feature only because we used to interpret any non-empty string to mean "yes please test". They no longer test that feature. In addition, we are forgiving of common setup failures (e.g., you do not have apache installed, or have an old version) when the tri-state is "auto" (or unset), but report an error when it is "true". This makes "auto" a sane default, as we should not cause failures on setups where the tests cannot run. But it allows people who use "true" to catch regressions in their system (e.g., they uninstalled apache, but were expecting their automated test runs to test git-httpd, and would want to be notified).

2013-11-26test: replace shebangs with descriptions in shell librariesLibravatar Jonathan Nieder1-1/+2
A #! line in these files is misleading, since these scriptlets are meant to be sourced with '.' (using whatever shell sources them) instead of run directly using the interpreter named on the #! line. Removing the #! line shouldn't hurt syntax highlighting since these files have filenames ending with '.sh'. For documentation, add a brief description of how the files are meant to be used in place of the shebang line.

2013-10-29t: use perl instead of "$PERL_PATH" where applicableLibravatar Jeff King1-3/+3
As of the last commit, we can use "perl" instead of "$PERL_PATH" when running tests, as the former is now a function which uses the latter. As the shorter "perl" is easier on the eyes, let's switch to using it everywhere. This is not quite a mechanical s/$PERL_PATH/perl/ replacement, though. There are some places where we invoke perl from a script we generate on the fly, and those scripts do not have access to our internal shell functions. The result can be double-checked by running: ln -s /bin/false bin-wrappers/perl make test which continues to pass even after this patch.

2013-10-29t: provide a perl() function which uses $PERL_PATHLibravatar Jeff King1-0/+4
Once upon a time, we assumed that calling a bare "perl" in the test scripts was OK, because we would find the perl from the user's PATH, and we were only asking that perl to do basic operations that work even on old versions of perl. Later, we found that some systems really prefer to use $PERL_PATH even for these basic cases, because the system perl misbehaves in some way (e.g., by handling line endings differently). We then switched "perl" invocations to "$PERL_PATH" to respect the user's choice. Having to use "$PERL_PATH" is ugly and cumbersome, though. Instead, let's provide a perl() shell function that tests can use, which will transparently do the right thing. Unfortunately, test writers still have to use $PERL_PATH in certain situations, so we still need to keep the advice in the README. Note that this may fix test failures in t5004, t5503, t6002, t6003, t6300, t8001, and t8002, depending on your system's perl setup. All of these can be detected by running: ln -s /bin/false bin-wrappers/perl make test which fails before this patch, and passes after.

2013-10-28Windows: a test_cmp that is agnostic to random LF <> CRLF conversionsLibravatar Johannes Sixt1-0/+66
In a number of tests, output that was produced by a shell script is compared to expected output using test_cmp. Unfortunately, the MSYS bash-- when invoked via git, such as in hooks--converts LF to CRLF on output (as produced by echo and printf), which leads to many false positives. Implements a diff tool that undoes the converted CRLF. To avoid that sub-processes are spawned (which is very slow on Windows), the tool is implemented as a shell function. Diff is invoked as usual only when a difference is detected by the shell code. Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2013-03-22apply --whitespace=fix: avoid running over the postimage bufferLibravatar Junio C Hamano1-2/+2
Originally update-pre-post-images could assume that any whitespace fixing will make the result only shorter by unexpanding runs of leading SPs into HTs and removing trailing whitespaces at the end of lines. Updating the post-image we read from the patch to match the actual result can be performed in-place under this assumption. These days, however, we have tab-in-indent (aka Python) rule whose result can be longer than the original, and we do need to allocate a larger buffer than the input and replace the result. Fortunately the support for lengthening rewrite was already added when we began supporting "match while ignoring whitespace differences" mode in 86c91f91794c (git apply: option to ignore whitespace differences, 2009-08-04). We only need to correctly count the number of bytes necessary to hold the updated result and tell the function to allocate a new buffer. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2012-11-15test-lib: allow negation of prerequisitesLibravatar Jeff King1-1/+20
You can set and test a prerequisite like this: test_set_prereq FOO test_have_prereq FOO && echo yes You can negate the test in the shell like this: ! test_have_prereq && echo no However, when you are using the automatic prerequisite checking in test_expect_*, there is no opportunity to use the shell negation. This patch introduces the syntax "!FOO" to indicate that the test should only run if a prerequisite is not meant. One alternative is to set an explicit negative prerequisite, like: if system_has_foo; then test_set_prereq FOO else test_set_prereq NO_FOO fi However, this doesn't work for lazy prerequisites, which associate a single test with a single name. We could teach the lazy prereq evaluator to set both forms, but the code change ends up quite similar to this one (because we still need to convert NO_FOO into FOO to find the correct lazy script).

Jeff King wrote: The seq command is GNU-ism, and is missing at least in older BSD releases and their derivatives, not to mention antique commercial Unixes. We already purged it in b3431bc (Don't use seq in tests, not everyone has it, 2007-05-02), but a few new instances have crept in. They went unnoticed because they are in scripts that are not run by default. Replace them with test_seq that is implemented with a Perl snippet (proposed by Jeff). This is better than inlining this snippet everywhere it's needed because it's easier to read and it's easier to change the implementation (e.g. to C) if we ever decide to remove Perl from the test suite. Note that test_seq is not a complete replacement for seq(1). It just has what we need now, in addition that it makes it possible for us to do something like "test_seq a m" if we wanted to in the future. There are also many places that do `for i in 1 2 3 ...` but I'm not sure if it's worth converting them to test_seq. That would introduce running more processes of Perl.

2012-07-27test: allow prerequisite to be evaluated lazilyLibravatar Junio C Hamano1-0/+42
The test prerequisite mechanism is a useful way to allow some tests in a test script to be skipped in environments that do not support certain features (e.g. it is pointless to attempt checking how well symbolic links are handled by Git on filesystems that do not support them). It is OK for commonly used prerequisites to be always tested during start-up of a test script by having a codeblock that tests a feature and calls test_set_prereq, but for an uncommon feature, forcing 90% of scripts to pay the same probing overhead for prerequisite they do not care about is wasteful. Introduce a mechanism to probe the prerequiste lazily. Changes are: - test_lazy_prereq () function, which takes the name of the prerequisite it probes and the script to probe for it, is added. This only registers the name of the prerequiste that can be lazily probed and the script to eval (without running). - test_have_prereq() function (which is used by test_expect_success and also can be called directly by test scripts) learns to look at the list of prerequisites that can be lazily probed, and the prerequisites that have already been probed that way. When asked for a prerequiste that can be but haven't been probed, the script registered with an earlier call to test_lazy_prereq is evaluated and the prerequisite is set. - test_run_lazy_prereq_() function is a helper to run the probe script with the same kind of sandbox as regular tests, helped by Jeff King. Update the codeblock to probe and set SYMLINKS prerequisite using the new mechanism as an example. Signed-off-by: Junio C Hamano <gitster@pobox.com>
