2012-08-04tests: Introduce test_seqLibravatar Michał Kiedrowicz1-0/+21
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.

2012-07-30Merge branch 'jc/maint-filter-branch-epoch-date' into maintLibravatar Junio C Hamano1-2/+11
In 1.7.9 era, we taught "git rebase" about the raw timestamp format but we did not teach the same trick to "filter-branch", which rolled a similar logic on its own. * jc/maint-filter-branch-epoch-date: t7003: add test to filter a branch with a commit at epoch date.c: Fix off by one error in object-header date parsing filter-branch: do not forget the '@' prefix to force git-timestamp
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>
2012-07-27test: rename $satisfied to $satisfied_prereqLibravatar Junio C Hamano1-3/+3
All other shell variables that are used to globally keep track of states related to prerequisite have "prereq" somewhere in their names. Be consistent and avoid potential name crashes with other kinds of satisfaction in the future. Signed-off-by: Junio C Hamano <gitster@pobox.com>

In 1.7.9 era, we taught "git rebase" about the raw timestamp format but we did not teach the same trick to "filter-branch", which rolled a similar logic on its own. Because of this, "filter-branch" failed to rewrite commits with ancient timestamps. * jc/maint-filter-branch-epoch-date: t7003: add test to filter a branch with a commit at epoch date.c: Fix off by one error in object-header date parsing filter-branch: do not forget the '@' prefix to force git-timestamp
2012-06-24tests: enclose $PERL_PATH in double quotesLibravatar Junio C Hamano1-2/+2
Otherwise it will be split at a space after "Program" when it is set to "\\Program Files\perl" or something silly like that. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-06-12t: Replace 'perl' by $PERL_PATHLibravatar Vincent van Ravesteijn1-2/+2
GIT-BUILD-OPTIONS defines PERL_PATH to be used in the test suite. Only a few tests already actually use this variable when perl is needed. The other test just call 'perl' and it might happen that the wrong perl interpreter is used. This becomes problematic on Windows, when the perl interpreter that is compiled and installed on the Windows system is used, because this perl interpreter might introduce some unexpected LF->CRLF conversions. This patch makes sure that $PERL_PATH is used everywhere in the test suite and that the correct perl interpreter is used.
