Many tests that check the behaviour of symbolic links stored in the index or the tree objects do not have to be skipped on a filesystem that lack symbolic link support. * js/test-ln-s-add: t4011: remove SYMLINKS prerequisite t6035: use test_ln_s_add to remove SYMLINKS prerequisite t3509, t4023, t4114: use test_ln_s_add to remove SYMLINKS prerequisite t3100: use test_ln_s_add to remove SYMLINKS prerequisite t3030: use test_ln_s_add to remove SYMLINKS prerequisite t0000: use test_ln_s_add to remove SYMLINKS prerequisite tests: use test_ln_s_add to remove SYMLINKS prerequisite (trivial cases) tests: introduce test_ln_s_add t3010: modernize style test-chmtime: Fix exit code on Windows

/*

|
* This program can either change modification time of the given
|
|
* file(s) or just print it. The program does not change atime nor
|
|
* ctime (their values are explicitly preserved).
|
|
*
|
|
* The mtime can be changed to an absolute value:
|
|
*
|
|
* test-chmtime =<seconds> file...
|
|
*
|
|
* Relative to the current time as returned by time(3):
|
|
*
|
|
* test-chmtime =+<seconds> (or =-<seconds>) file...
|
|
*
|
|
* Or relative to the current mtime of the file:
|
|
*
|
|
* test-chmtime <seconds> file...
|
|
* test-chmtime +<seconds> (or -<seconds>) file...
|
|
*
|
|
* Examples:
|
|
*
|
|
* To just print the mtime use --verbose and set the file mtime offset to 0:
|
|
*
|
|
* test-chmtime -v +0 file
|
|
*
|
|
* To set the mtime to current time:
|
|
*
|
|
* test-chmtime =+0 file
