[PATCH v2 0/5] modernize t1500
Locked
 
|
This is a re-roll of [1] which modernizes t1500 by updating tests to set
up their own needed state rather than relying upon manipulation of global state. Changes since v1[1]: In v1 patch 1/6, which makes test_rev_parse() for-loop driven, the loop control has been moved to the top of the loop for improved robustness. v1 patch 2/6, which tweaked the value of GIT_CONFIG in preparation for removal of global cd's has been squashed into patch 3/6 which actually removes the cd's since the below diff makes perfect sense in the context of the latter patch, thus doesn't require its own preparatory patch. -cd work || exit 1 -GIT_CONFIG="$(pwd)"/../.git/config +GIT_CONFIG="$(pwd)/work/../.git/config" v1 patch 3/6, which teaches test_rev_parse() the -C option, has been revised to ensure that the argument to -C is always quoted upon use to avoid problems with whitespace in directory names (though current tests don't have any such directories). v1 patches 4/6 and 5/6, which teach test_rev_parse() the -b and -g options, no longer assigns shell code to a variable for later execution/evaluation; instead they just execute the code directly. v1 patch 5/6 ensures that the argument to -g is properly quoted when assigned to GIT_DIR to avoid problems with whitespace in directory names. v1 patch 6/6, which changes "mv .git repo.git" to "cp -R .git repo.git", has been squashed with Junio's 7/6[2], which moves the "cp -R" earlier in the script, and now sits at the front of the series. Other setup-related actions have likewise been moved into a common "setup" test[3]. Most commit messages have seen minor tweaks. A v1 to v2 interdiff is included below.

[PATCH v2 1/5] t1500: be considerate to future potential tests
|
|
The final batch of git-rev-parse tests work against a non-local object
database named repo.git. This is done by renaming .git to repo.git and pointing GIT_DIR at it, but the name is never restored to .git at the end of the script, which can be problematic for tests added in the future. Be more friendly by instead making repo.git a copy of .git. Furthermore, make it clear that tests in repo.git will be independent from the results of earlier tests done in .git by initializing repo.git earlier in the test sequence. Likewise, bundle remaining preparation (such as directory creation) into a common setup test consistent with modern practice.

In reply to this post by Eric Sunshine
Tests run by test_rev_parse() are nearly identical; each invokes
git-rev-parse with a single option and compares the result against an expected value. Such duplication makes it onerous to extend the tests since any change needs to be repeated in each test. Avoid the duplication by parameterizing the test and driving it via a for-loop.

[PATCH v2 4/5] t1500: avoid setting configuration options outside of tests
|
|
In reply to this post by Eric Sunshine
Ideally, each test should be responsible for setting up state it needs
rather than relying upon transient global state. Toward this end, teach test_rev_parse() to accept a "-b <value>" option to allow callers to set "core.bare" explicitly or undefine it. Take advantage of this new option to avoid setting "core.bare" outside of tests. Under the hood, "-b <value>" invokes "test_config -C <dir>" (or "test_unconfig -C <dir>"), thus git-config knows explicitly where to find its configuration file. Consequently, the global GIT_CONFIG environment variable required by the manual git-config invocations outside of tests is no longer needed, and is thus dropped.

[PATCH v2 5/5] t1500: avoid setting environment variables outside of tests
|
|
In reply to this post by Eric Sunshine
Ideally, each test should be responsible for setting up state it needs
rather than relying upon transient global state. Toward this end, teach test_rev_parse() to accept a "-g <dir>" option to allow callers to specify the value of the GIT_DIR environment variable explicitly. Take advantage of this new option to avoid polluting the global scope with GIT_DIR assignments. Implementation note: Typically, tests avoid polluting the global state by wrapping transient environment variable assignments within a subshell, however, this technique doesn't work here since test_config() and test_unconfig() need to know GIT_DIR, as well, but neither function can be used within a subshell. Consequently, GIT_DIR is instead cleared manually via test_when_finished().

However, the idea popped up in an other thread[1] that we might want something like 'git rev-parse --absolute-path --git-dir', which wouldn't really work with '--$o'. Even if we don't go that route, perhaps it would be better to list the options to be tested including their doubledash prefix.

As this series is only about modernizing t1500, I'd prefer to keep the conversion faithful to the original which titles each test "$name: is-bare-repository", "$name: is-inside-git-dir", etc., and the current approach does so without additional complexity. I have no objection to upgrading the for-loop items to include the leading dashes or updating the logic to support --absolute-path, but such changes are outside the scope of this series and can easily be built atop it. Also, due to severe time constraints, I'd rather not re-roll only for a superficial and subjective change such as adding leading dashes to for-loop items.

On reflection, I agree with your points and will include the change in the re-roll.
