2013-06-02object_array_entry: fix memory handling of the name fieldLibravatar Michael Haggerty4-7/+35
Previously, the memory management of the object_array_entry::name field was inconsistent and undocumented. object_array_entries are ultimately created by a single function, add_object_array_with_mode(), which has an argument "const char *name". This function used to simply set the name field to reference the string pointed to by the name parameter, and nobody on the object_array side ever freed the memory. Thus, it assumed that the memory for the name field would be managed by the caller, and that the lifetime of that string would be at least as long as the lifetime of the object_array_entry. But callers were inconsistent: * Some passed pointers to constant strings or argv entries, which was OK. * Some passed pointers to newly-allocated memory, but didn't arrange for the memory ever to be freed. * Some passed the return value of sha1_to_hex(), which is a pointer to a statically-allocated buffer that can be overwritten at any time. * Some passed pointers to refnames that they received from a for_each_ref()-type iteration, but the lifetimes of such refnames is not guaranteed by the refs API. Bring consistency to this mess by changing object_array to make its own copy for the object_array_entry::name field and free this memory when an object_array_entry is deleted from the array. Many callers were passing the empty string as the name parameter, so as a performance optimization, treat the empty string specially. Instead of making a copy, store a pointer to a statically-allocated empty string to object_array_entry::name. When deleting such an entry, skip the free(). Change the callers that were already passing copies to add_object_array_with_mode() to either skip the copy, or (if the memory needed to be allocated anyway) freeing the memory itself. A part of this commit effectively reverts 70d26c6e76 read_revisions_from_stdin: make copies for handle_revision_arg because the copying introduced by that commit (which is still necessary) is now done at a deeper level.

2013-05-28find_first_merges(): remove unnecessary codeLibravatar Michael Haggerty1-2/+1

2013-05-28fsck: don't put a void*-shaped peg in a char*-shaped holeLibravatar Michael Haggerty1-1/+1
The source of this nonsense was 04d3975937 fsck: reduce stack footprint , which wedged a pointer to parent into the object_array_entry's name field. The parent pointer was passed to traverse_one_object(), even though that function *didn't use it*. The useless code has been deleted over time. Commit a1cdc25172 fsck: drop unused parameter from traverse_one_object() removed the parent pointer from traverse_one_object()'s signature. Commit c0aa335c95 Remove unused variables removed the code that read the parent pointer back out of the name field. This commit takes the last step: don't write the parent pointer into the name field in the first place.

2013-05-28object_array_remove_duplicates(): rewrite to reduce copyingLibravatar Michael Haggerty2-12/+26
The old version copied one entry to its destination position, then deleted any matching entries from the tail of the array. This required the tail of the array to be copied multiple times. It didn't affect the complexity of the algorithm because the whole tail has to be searched through anyway. But all the copying was unnecessary. Instead, check for the existence of an entry with the same name in the *head* of the list before copying an entry to its final position. This way each entry has to be copied at most one time. Extract a helper function contains_name() to do a bit of the work. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2013-05-28cmd_diff(): make it obvious which cases are exclusive of each otherLibravatar Michael Haggerty1-5/+4
At first glance the OBJ_COMMIT, OBJ_TREE, and OBJ_BLOB cases look like they might be mutually exclusive. But the OBJ_COMMIT case doesn't end the loop iteration with "continue" like the other two cases, but rather falls through. So use if...else if...else construct to make it more obvious that only the last two cases are mutually exclusive.
