The read_cache() in prepare_to_commit() would end up clobbering the pointer we had for a previously populated "the_index.cache_tree" in the very common case of "git commit" stressed by e.g. the tests being changed here. We'd populate "the_index.cache_tree" by calling "update_main_cache_tree" in prepare_index(), but would not end up with a "fully prepared" index. What constitutes an existing index is clearly overly fuzzy, here we'll check "active_nr" (aka "the_index.cache_nr"), but our "the_index.cache_tree" might have been malloc()'d already. Thus the code added in11c8a74a64(commit: write cache-tree data when writing index anyway, 2011-12-06) would end up allocating the "cache_tree", and would interact here with code added in7168624c35(Do not generate full commit log message if it is not going to be used, 2007-11-28). The result was a very common memory leak. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Taylor Blau <me@ttaylorr.com>

test_description='git ls-files -k and -m flags test.
|
|
|
|
This test prepares the following in the cache:
|
|
|
|
path0 - a file
|
|
path1 - a symlink
|
|
path2/file2 - a file in a directory
|
|
path3/file3 - a file in a directory
|
|
pathx/ju - a file in a directory
|
|
submod1/ - a submodule
|
|
submod2/ - another submodule
|
|
|
|
and the following on the filesystem:
|
|
|
|
path0/file0 - a file in a directory
|
|
path1/file1 - a file in a directory
|
|
path2 - a file
|
|
path3 - a symlink
|
|
path4 - a file
|
|
path5 - a symlink
|
|
path6/file6 - a file in a directory
|
|
pathx/ju/nk - a file in a directory to be killed
|
|
submod1/ - a submodule (modified from the cache)
|
|
submod2/ - a submodule (matches the cache)
|
|
|
|
git ls-files -k should report that existing filesystem objects
|
|
path0/*, path1/*, path2 and path3 to be killed.
|
|
|
|
Also for modification test, the cache and working tree have:
|
|
|
|
path7 - an empty file, modified to a non-empty file.
|
|
path8 - a non-empty file, modified to an empty file.
|
|
path9 - an empty file, cache dirtied.
|
|
path10 - a non-empty file, cache dirtied.
|
|
|
|
We should report path0, path1, path2/file2, path3/file3, path7 and path8
|
|
modified without reporting path9 and path10. submod1 is also modified.
