2013-12-16Prevent buffer overflows when path is too longLibravatar Antoine Pelisse1-24/+27
Some buffers created with PATH_MAX length are not checked when being written, and can overflow if PATH_MAX is not big enough to hold the path. Replace those buffers by strbufs so that their size is automatically grown if necessary. They are created as static local variables to avoid reallocating memory on each call. Note that prefix_filename() returns this static buffer so each callers should copy or use the string immediately (this is currently true).

2013-11-04unpack-trees: fix "read-tree -u --reset A B" with conflicted indexLibravatar Jeff King1-8/+17
When we call "read-tree --reset -u HEAD ORIG_HEAD", the first thing we do with the index is to call read_cache_unmerged. Originally that would read the index, leaving aside any unmerged entries. However, as of d1a43f2 (reset --hard/read-tree --reset -u: remove unmerged new paths, 2008-10-15), it actually creates a new cache entry to serve as a placeholder, so that we later know to update the working tree. However, we later noticed that the sha1 of that unmerged entry was just copied from some higher stage, leaving you with random content in the index. That was fixed by e11d7b5 ("reset --merge": fix unmerged case, 2009-12-31), which instead puts the null sha1 into the newly created entry, and sets a CE_CONFLICTED flag. At the same time, it teaches the unpack-trees machinery to pay attention to this flag, so that oneway_merge throws away the current value. However, it did not update the code paths for twoway_merge, which is where we end up in the two-way read-tree with --reset. We notice that the HEAD and ORIG_HEAD versions are the same, and say "oh, we can just reuse the current version". But that's not true. The current version is bogus. Notice this case and make sure we do not keep the bogus entry; either we do not have that path in the tree we are moving to (i.e. remove it), or we want to have the cache entry we created for the tree we are moving to (i.e. resolve by explicitly saying the "newtree" version is what we want).

2013-09-17employ new explicit "exists in index?" APILibravatar Eric Sunshine1-2/+2
Each caller of index_name_exists() knows whether it is looking for a directory or a file, and can avoid the unnecessary indirection of index_name_exists() by instead calling index_dir_exists() or index_file_exists() directly. Invoking the appropriate search function explicitly will allow a subsequent patch to relieve callers of the artificial burden of having to add a trailing '/' to the pathname given to index_dir_exists().

2013-07-09Convert "struct cache_entry *" to "const ..." wherever possibleLibravatar Nguyễn Thái Ngọc Duy1-7/+7
I attempted to make index_state->cache[] a "const struct cache_entry **" to find out how existing entries in index are modified and where. The question I have is what do we do if we really need to keep track of on-disk changes in the index. The result is - diff-lib.c: setting CE_UPTODATE - name-hash.c: setting CE_HASHED - preload-index.c, read-cache.c, unpack-trees.c and builtin/update-index: obvious - entry.c: write_entry() may refresh the checked out entry via fill_stat_cache_info(). This causes "non-const struct cache_entry *" in builtin/apply.c, builtin/checkout-index.c and builtin/checkout.c - builtin/ls-files.c: --with-tree changes stagemask and may set CE_UPDATE Of these, write_entry() and its call sites are probably most interesting because it modifies on-disk info. But this is stat info and can be retrieved via refresh, at least for porcelain commands. Other just uses ce_flags for local purposes. So, keeping track of "dirty" entries is just a matter of setting a flag in index modification functions exposed by read-cache.c. Except unpack-trees, the rest of the code base does not do anything funny behind read-cache's back. The actual patch is less valueable than the summary above. But if anyone wants to re-identify the above sites. Applying this patch, then this: diff --git a/cache.h b/cache.h index 430d021..1692891 100644 --- a/cache.h +++ b/cache.h @@ -267,7 +267,7 @@ static inline unsigned int canon_mode(unsigned int mode) #define cache_entry_size(len) (offsetof(struct cache_entry,name) + (len) + 1) struct index_state { - struct cache_entry **cache; + const struct cache_entry **cache; unsigned int version; unsigned int cache_nr, cache_alloc, cache_changed; struct string_list *resolve_undo; will help quickly identify them without bogus warnings.

2013-06-02diff-lib, read-tree, unpack-trees: mark cache_entry array paramters constLibravatar René Scharfe1-8/+13
Change the type merge_fn_t to accept the array of cache_entry pointers as const pointers to const pointers. This documents the fact that the merge functions don't modify the cache_entry contents or replace any of the pointers in the array. Only a single cast is necessary in unpack_nondirectories because adding two const modifiers at once is not allowed in C. The cast is safe in that it doesn't mask any modfication; call_unpack_fn only needs the array for reading.

2013-06-02unpack-trees: create working copy of merge entry in merged_entryLibravatar René Scharfe1-5/+12
Duplicate the merge entry right away and work with that instead of modifying the entry we got and duplicating it only at the end of the function. Then mark that pointer const to document that we don't modify the referenced cache_entry. This change is safe because all existing merge functions call merged_entry just before returning (or not at all), i.e. they don't care about changes to the referenced cache_entry after the call. unpack_nondirectories and unpack_index_entry, which call the merge functions through call_unpack_fn, aren't interested in such changes neither. The change complicates merged_entry a bit because we have to free the copy if we error out, but allows callers to pass a const pointer.

2013-01-06dir.c: use a single struct exclude_list per source of excludesLibravatar Adam Spiers1-1/+1
Previously each exclude_list could potentially contain patterns from multiple sources. For example dir->exclude_list[EXC_FILE] would typically contain patterns from .git/info/exclude and core.excludesfile, and dir->exclude_list[EXC_DIRS] could contain patterns from multiple per-directory .gitignore files during directory traversal (i.e. when dir->exclude_stack was more than one item deep). We split these composite exclude_lists up into three groups of exclude_lists (EXC_CMDL / EXC_DIRS / EXC_FILE as before), so that each exclude_list now contains patterns from a single source. This will allow us to cleanly track the origin of each pattern simply by adding a src field to struct exclude_list, rather than to struct exclude, which would make memory management of the source string tricky in the EXC_DIRS case where its contents are dynamically generated. Similarly, by moving the filebuf member from struct exclude_stack to struct exclude_list, it allows us to track and subsequently free memory buffers allocated during the parsing of all exclude files, rather than only tracking buffers allocated for files in the EXC_DIRS group.

Although the subject line of 613f027 (read-tree -u one-way merge fix to check out locally modified paths., 2006-05-15) mentions "read-tree -u", it did not seem to check whether -u was in effect.

Strip the name length from the ce_flags field and move it into its own ce_namelen field in struct cache_entry. This will both give us a tiny bit of a performance enhancement when working with long pathnames and is a refactoring for more readability of the code. It enhances readability, by making it more clear what is a flag, and where the length is stored and make it clear which functions use stages in comparisions and which only use the length. It also makes CE_NAMEMASK private, so that users don't mistakenly write the name length in the flags.

2011-08-29unpack-trees: allow pruning with pathspecLibravatar Junio C Hamano1-0/+2
Use the pathspec pruning of traverse_trees() from unpack_trees(). Again, the unpack_trees() machinery is primarily meant for merging two (or more) trees, and because a merge is a full tree operation, it didn't support any pruning with pathspec, and this codepath probably should not be enabled while running a merge, but the caller in diff-lib.c::diff_cache() should be able to take advantage of it.

2011-07-31Break down no-lstat() condition checks in verify_uptodate()Libravatar Nguyễn Thái Ngọc Duy1-2/+13
Make it easier to grok under what conditions we can skip lstat(). While at there, shorten ie_match_stat() line for the sake of my eyes. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
