Many tests depend on that symbolic links work. This introduces a check
that sets the prerequisite tag SYMLINKS if the file system supports
symbolic links. Since so many tests have to check for this prerequisite,
we do the check in test-lib.sh, so that we don't need to repeat the test
in many scripts.
To check for 'ln -s' failures, you can use a FAT partition on Linux:
$ mkdosfs -C git-on-fat 1000000
$ sudo mount -o loop,uid=j6t,gid=users,shortname=winnt git-on-fat /mnt
Clone git to /mnt and
$ GIT_SKIP_TESTS='t0001.1[34] t0010 t1301 t403[34] t4129.[47] t5701.7
t7701.3 t9100 t9101.26 t9119 t9124.[67] t9200.10 t9600.6' \
make test
(These additionally skipped tests depend on POSIX permissions that FAT on
Linux does not provide.)

test_description='Test the very basics part #1.
|
|
|
|
The rest of the test suite does not check the basic operation of git
|
|
plumbing commands to work very carefully. Their job is to concentrate
|
|
on tricky features that caused bugs in the past to detect regression.
|
|
|
|
This test runs very basic features, like registering things in cache,
|
|
writing tree, etc.
|
|
|
|
Note that this test *deliberately* hard-codes many expected object
|
|
IDs. When object ID computation changes, like in the previous case of
|
|
swapping compression and hashing order, the person who is making the
|
|
modification *should* take notice and update the test vectors here.
