* untracked cache: invalidate at index addition or removalNguyễn Thái Ngọc Duy2015-03-121-2/+5
| | | | | | | | | | | | | | | | | Ideally we should implement untracked_cache_remove_from_index() and untracked_cache_add_to_index() so that they update untracked cache right away instead of invalidating it and wait for read_directory() next time to deal with it. But that may need some more work in unpack-trees.c. So stay simple as the first step. The new call in add_index_entry_with_check() may look strange because new calls usually stay close to cache_tree_invalidate_path(). We do it a bit later than c_t_i_p() in this function because if it's about replacing the entry with the same name, we don't care (but cache-tree does).

While at it, inline the o->gently check into reject_merge to prevent future call sites from making the same mistake. Noticed by code inspection. The test for the motivating case was added by JC.

Moreover, any of the three entries, if present, would have the same path because there is no rename detection in this code path. Even if some day in the future the entries' paths differ, the 'current' path used in the index and worktree would presumably be the most recognizable for the end user.

(Read cost is another matter, to be dealt separately.) This mode stores index info in a pair of $GIT_DIR/index and $GIT_DIR/sharedindex.<SHA-1>. sharedindex is large and unchanged over time while "index" is smaller and updated often. Format details are in index-format.txt, although not everything is implemented in this patch. Shared indexes are not automatically removed, because it's unclear if the shared index is needed by any (even temporary) indexes by just looking at it. After a while you'll collect stale shared indexes. The good news is one shared index is useable for long, until $GIT_DIR/index becomes too big and sluggish that the new shared index must be created. The safest way to clean shared indexes is to turn off split index mode, so shared files are all garbage, delete them all, then turn on split index mode again.

To compare a pair of such counted strings, unpack-trees.c and read-cache.c implement their own name_compare() functions identically. In addition, the cache_name_compare() function in read-cache.c is nearly identical. The only difference is when one string is the prefix of the other string, in which case name_compare() returns -1/+1 to show which one is longer, and cache_name_compare() returns the difference of the lengths to show the same information. Unify these three functions by using the implementation from cache_name_compare(). This does not make any difference to the existing and future callers, as they must be paying attention only to the sign of the returned value (and not the magnitude) because the original implementations of these two functions return values returned by memcmp(3) when the one string is not a prefix of the other string, and the only thing memcmp(3) guarantees its callers is the sign of the returned value, not the magnitude.

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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

* | Convert "struct cache_entry *" to "const ..." wherever possiblend/const-struct-cache-entryNguyễn Thái Ngọc Duy2013-07-091-7/+7

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.

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.

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.

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.
