Jeff King	c12f82ae63	diff: test precedence of external diff drivers There are three ways to specify an external diff command: GIT_EXTERNAL_DIFF in the environment, diff.external in the config, or a "diff" gitattribute. The current order of precedence is: 1. gitattribute 2. GIT_EXTERNAL_DIFF 3. diff.external Usually our rule is that environment variables should take precedence over on-disk config (i.e., option 2 should come before option 1). However, this situation is trickier than some, because option 1 is more specific to the individual file than option 2 (which affects all files), so it might be preferable. So the current behavior can be seen as implementing "do the specific thing if we can, but fall back to this general thing". This is probably not what we would do if we were writing git from scratch, but it has been this way for several years, and is not worth changing. So let's at least document that this is the way it's supposed to work with a test. While we're there, let's also make sure that diff.external (which was not previously tested at all) works by running it through the same tests as GIT_EXTERNAL_DIFF.

Junio C Hamano	bd8c1a9b49	diff: correctly disable external_diff with --no-ext-diff Upon seeing a type-change filepair, "diff --no-ext-diff" does not show the usual "deletion followed by addition" split patch and does not run the external diff driver either. This is because the logic to disable external diff was placed at a wrong level in the callchain. run_diff_cmd() decides to show the split patch only when external diff driver is not configured or specified via GIT_EXTERNAL_DIFF environment, but this is done before checking if --no-ext-diff was given. To make things worse, run_diff_cmd() checks --no-ext-diff and disables the output for such a filepair completely, as the callchain below it (e.g. builtin_diff) does not want to handle typechange filepairs.

Junio C Hamano	7096b6486e	tests: enclose $PERL_PATH in double quotes 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>	13 years ago
Vincent van Ravesteijn	a3428205e6	t: Replace 'perl' by $PERL_PATH 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.

Junio C Hamano	3749fde561	test: use $_z40 from test-lib There is no need to duplicate the definition of $_z40 and $_x40 that test-lib.sh supplies the test scripts. Signed-off-by: Junio C Hamano <gitster@pobox.com>	14 years ago
Jeff King	eaf0551d56	tests: use "$TEST_DIRECTORY" instead of ".." The $TEST_DIRECTORY variable allows tests to find the top-level test directory regardless of the current working directory. In the past, this has been used to accomodate tests which change directories, but it is also the first step to being able to move trash directories outside of the $TEST_DIRECTORY hierarchy.

David Aguilar	003b33a8ad	diff: generate pretty filenames in prep_temp_blob() Naturally, prep_temp_blob() did not care about filenames. As a result, GIT_EXTERNAL_DIFF and textconv generated filenames such as ".diff_XXXXXX". This modifies prep_temp_blob() to generate user-friendly filenames when creating temporary files. Diffing "name.ext" now generates "XXXXXX_name.ext". Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	16 years ago
Junio C Hamano	150115aded	diff --cached: do not borrow from a work tree when a path is marked as assume-unchanged When the index says that the file in the work tree that corresponds to the blob object that is used for comparison is known to be unchanged, "diff" reads from the file and applies convert_to_git(), instead of inflating the object, to feed the internal diff engine with, because an earlier benchnark found that it tends to be faster to use this optimization. However, the index can lie when the path is marked as assume-unchanged. Disable the optimization for such paths. Signed-off-by: Junio C Hamano <gitster@pobox.com>	16 years ago
Johannes Schindelin	4e218f54b3	Smudge the files fed to external diff and textconv When preparing temporary files for an external diff or textconv, it is easier on the external tools, especially when they are implemented using platform tools, if they are fed the input after convert_to_working_tree(). This fixes msysGit issue 177. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>	16 years ago
Nazri Ramliy	a8344abe0f	Bugfix: GIT_EXTERNAL_DIFF with more than one changed files When there is more than one file that are changed, running git diff with GIT_EXTERNAL_DIFF incorrectly diagnoses an programming error and dies. The check introduced in `479b0ae` (diff: refactor tempfile cleanup handling, 2009-01-22) to detect a temporary file slot that forgot to remove its temporary file was inconsistent with the way the codepath to remove the temporary to mark the slot that it is done with it. This patch fixes this problem and adds a test case for it.

Junio C Hamano	61af494ca4	Teach "git diff" to honour --[no-]ext-diff The original intention of `72909be` (Add diff-option --ext-diff, 2007-06-30) was to optionally allow the use of external diff viewer in "git log" family (while keeping them disabled by default). It exposed the "allow external diff" bit to the UI, but forgot to adjust the "git diff" codepath that was set up to always allow use of the external diff viewer. Noticed by Nazri Ramliy; tests by René Scharfe squashed in. Signed-off-by: Junio C Hamano <gitster@pobox.com>	16 years ago
Junio C Hamano	bfdbee9810	tests: use $TEST_DIRECTORY to refer to the t/ directory Many test scripts assumed that they will start in a 'trash' subdirectory that is a single level down from the t/ directory, and referred to their test vector files by asking for files like "../t9999/expect". This will break if we move the 'trash' subdirectory elsewhere. To solve this, we earlier introduced "$TEST_DIRECTORY" so that they can refer to t/ directory reliably. This finally makes all the tests use it to refer to the outside environment. With this patch, and a one-liner not included here (because it would contradict with what Dscho really wants to do): \| diff --git a/t/test-lib.sh b/t/test-lib.sh \| index 70ea7e0..60e69e4 100644 \| --- a/t/test-lib.sh \| +++ b/t/test-lib.sh \| @@ -485,7 +485,7 @@ fi \| . ../GIT-BUILD-OPTIONS \| \| # Test repository \| -test="trash directory" \| +test="trash directory/another level/yet another" \| rm -fr "$test" \|\| { \| trap - exit \| echo >&5 "FATAL: Cannot prepare test area" all the tests still pass, but we would want extra sets of eyeballs on this type of change to really make sure.

Jeff King	e85fe4d85b	more tr portability test script fixes Dealing with NULs is not always safe with tr. On Solaris, incoming NULs are silently deleted by both the System V and UCB versions of tr. When converting to NULs, the System V version works fine, but the UCB version silently ignores the request to convert the character. This patch changes all instances of tr using NULs to use "perl -pe 'y///'" instead. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 years ago
H.Merijn Brand	3175b0cfc1	the use of 'tr' in the test suite isn't really portable Some versions of 'tr' only accept octal codes if entered with three digits, and therefor misinterpret the '\0' in the test suite.

Junio C Hamano	f1af60bdba	Support 'diff=pgm' attribute This enhances the attributes mechanism so that external programs meant for existing GIT_EXTERNAL_DIFF interface can be specifed per path. To configure such a custom diff driver, first define a custom diff driver in the configuration: [diff "my-c-diff"] command = <<your command string comes here>> Then mark the paths that you want to use this custom driver using the attribute mechanism. *.c diff=my-c-diff The intent of this separation is that the attribute mechanism is used for specifying the type of the contents, while the configuration mechanism is used to define what needs to be done to that type of the contents, which would be specific to both platform and personal taste.
