Subject: [PATCH 5/5] cmake: avoid editing t/test-lib.sh
Date: Wed, 10 Aug 2022 15:02:30 +0000 [thread overview]
Message-ID: <c7fc5a4ee4cbc49b8afb2f9579763482552fffb0.1660143750.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1320.git.1660143750.gitgitgadget@gmail.com>
From: Johannes Schindelin <johannes.schindelin@gmx.de>
In 7f5397a07c6c (cmake: support for testing git when building out of the
source tree, 2020-06-26), we implemented support for running Git's test
scripts even after building Git in a different directory than the source
directory.
The way we did this was to edit the file `t/test-lib.sh` to override
`GIT_BUILD_DIR` to point somewhere else than the parent of the `t/`
directory.
This is unideal because it always leaves a tracked file marked as
modified, and it is all too easy to commit that change by mistake.
Let's change the strategy by teaching `t/test-lib.sh` to detect the
presence of a file called `GIT-BUILD-DIR` in the source directory. If it
exists, the contents are interpreted as the location to the _actual_
build directory. We then write this file as part of the CTest
definition.
To support building Git via a regular `make` invocation after building
it using CMake, we ensure that the `GIT-BUILD-DIR` file is deleted (for
convenience, this is done as part of the Makefile rule that is already
run with every `make` invocation to ensure that `GIT-BUILD-OPTIONS` is
up to date).
