2017-04-23Merge branch 'jh/unpack-trees-micro-optim'Libravatar Junio C Hamano1-5/+33
In a 2- and 3-way merge of trees, more than one source trees often end up sharing an identical subtree; optimize by not reading the same tree multiple times in such a case. * jh/unpack-trees-micro-optim: unpack-trees: avoid duplicate ODB lookups during checkout
2017-04-15unpack-trees: avoid duplicate ODB lookups during checkoutLibravatar Jeff Hostetler1-5/+33
Teach traverse_trees_recursive() to not do redundant ODB lookups when both directories refer to the same OID. In operations such as read-tree and checkout, there will likely be many peer directories that have the same OID when the differences between the commits are relatively small. In these cases we can avoid hitting the ODB multiple times for the same OID. This patch handles n=2 and n=3 cases and simply copies the data rather than repeating the fill_tree_descriptor(). ================ On the Windows repo (500K trees, 3.1M files, 450MB index), this reduced the overall time by 0.75 seconds when cycling between 2 commits with a single file difference.

In a later patch we'll support submodule entries to be in sync with the tree in working tree changing commands, such as checkout or read-tree. When a new submodule entry changes in the tree, we need to check if there are conflicts (directory/file conflicts) for the tree.

2017-02-03Merge branch 'sb/unpack-trees-super-prefix'Libravatar Junio C Hamano1-3/+40

2017-01-25unpack-trees: support super-prefix optionLibravatar Stefan Beller1-3/+40
In the future we want to support working tree operations within submodules, e.g. "git checkout --recurse-submodules", which will update the submodule to the commit as recorded in its superproject. In the submodule the unpack-tree operation is carried out as usual, but the reporting to the user needs to prefix any path with the superproject. The mechanism for this is the super-prefix. (see 74866d757, git: make super-prefix option) Add support for the super-prefix option for commands that unpack trees by wrapping any path output in unpacking trees in the newly introduced super_prefixed function. This new function prefixes any path with the super-prefix if there is one. Assuming the submodule case doesn't happen in the majority of the cases, we'd want to have a fast behavior for no super prefix, i.e. no reallocation/copying, but just returning path. Another aspect of introducing the `super_prefixed` function is to consider who owns the memory and if this is the right place where the path gets modified. As the super prefix ought to change the output behavior only and not the actual unpack tree part, it is fine to be that late in the line. As we get passed in 'const char *path', we cannot change the path itself, which means in case of a super prefix we have to copy over the path. We need two static buffers in that function as the error messages contain at most two paths. For testing purposes enable it in read-tree, which has no output of paths other than an unpack-trees.c. These are all converted in this patch. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-01-10unpack-trees: move checkout state into check_updatesLibravatar Stefan Beller1-12/+12
The checkout state was introduced via 16da134b1f9 (read-trees: refactor the unpack_trees() part, 2006-07-30). An attempt to refactor the checkout state was done in b56aa5b268e (unpack-trees: pass checkout state explicitly to check_updates(), 2016-09-13), but we can go even further. The `struct checkout state` is not used in unpack_trees apart from initializing it, so move it into the function that makes use of it, which is `check_updates`.

While unpacking trees (e.g. during git checkout), when we hit a cache entry that's past and outside our path, we cut off iteration. This provides about a 45% speedup on git checkout between master and master^20000 on Twitter's monorepo.

2016-01-05do_compare_entry: use already-computed pathLibravatar David Turner1-2/+36
In traverse_trees, we generate the complete traverse path for a traverse_info. Later, in do_compare_entry, we used to go do a bunch of work to compare the traverse_info to a cache_entry's name without computing that path. But since we already have that path, we don't need to do all that work. Instead, we can just put the generated path into the traverse_info, and do the comparison more directly. We copy the path because prune_traversal might mutate `base`. This doesn't happen in any codepaths where do_compare_entry is called, but it's better to be safe. This makes git checkout much faster -- about 25% on Twitter's monorepo. Deeper directory trees are likely to benefit more than shallower ones.

2015-09-25replace trivial malloc + sprintf / strcpy calls with xstrfmtLibravatar Jeff King1-3/+1
It's a common pattern to do: foo = xmalloc(strlen(one) + strlen(two) + 1 + 1); sprintf(foo, "%s %s", one, two); (or possibly some variant with strcpy()s or a more complicated length computation). We can switch these to use xstrfmt, which is shorter, involves less error-prone manual computation, and removes many sprintf and strcpy calls which make it harder to audit the code for real buffer overflows.

2015-09-04verify_absent: allow filenames longer than PATH_MAXLibravatar Jeff King1-7/+10
When unpack-trees wants to know whether a path will overwrite anything in the working tree, we use lstat() to see if there is anything there. But if we are going to write "foo/bar", we can't just lstat("foo/bar"); we need to look for leading prefixes (e.g., "foo"). So we use the lstat cache to find the length of the leading prefix, and copy the filename up to that length into a temporary buffer (since the original name is const, we cannot just stick a NUL in it). The copy we make goes into a PATH_MAX-sized buffer, which will overflow if the prefix is longer than PATH_MAX. How this happens is a little tricky, since in theory PATH_MAX is the biggest path we will have read from the filesystem. But this can happen if: - the compiled-in PATH_MAX does not accurately reflect what the filesystem is capable of - the leading prefix is not _quite_ what is on disk; it contains the next element from the name we are checking. So if we want to write "aaa/bbb/ccc/ddd" and "aaa/bbb" exists, the prefix of interest is "aaa/bbb/ccc". If "aaa/bbb" approaches PATH_MAX, then "ccc" can overflow it. So this can be triggered, but it's hard to do. In particular, you cannot just "git clone" a bogus repo. The verify_absent checks happen before unpack-trees writes anything to the filesystem, so there are never any leading prefixes during the initial checkout, and the bug doesn't trigger. And by definition, these files are larger than PATH_MAX, so writing them will fail, and clone will complain (though it may write a partial path, which will cause a subsequent "git checkout" to hit the bug). We can fix it by creating the temporary path on the heap. The extra malloc overhead is not important, as we are already making at least one stat() call (and probably more for the prefix discovery).

2015-08-10prefer git_pathdup to git_path in some possibly-dangerous casesLibravatar Jeff King1-1/+3
Because git_path uses a static buffer that is shared with calls to git_path, mkpath, etc, it can be dangerous to assign the result to a variable or pass it to a non-trivial function. The value may change unexpectedly due to other calls. None of the cases changed here has a known bug, but they're worth converting away from git_path because: 1. It's easy to use git_pathdup in these cases. 2. They use constructs (like assignment) that make it hard to tell whether they're safe or not. The extra malloc overhead should be trivial, as an allocation should be an order of magnitude cheaper than a system call (which we are clearly about to make, since we are constructing a filename).

Don't update files in the worktree from cache entries which are flagged with CE_WT_REMOVE. When a user does a sparse checkout, git removes files that are marked with CE_WT_REMOVE (because they are out-of-scope for the sparse checkout). If those files are also marked CE_UPDATE (for instance, because they differ in the branch that is being checked out and the outgoing branch), git would previously recreate them. This patch prevents them from being recreated. These erroneously-created files would also interfere with merges, causing pre-merge revisions of out-of-scope files to appear in the worktree. apply_sparse_checkout() is the function where all "action" manipulation (add, delete, update files..) for sparse checkout occurs; it should not ask to delete and update both at the same time.

2015-03-12untracked cache: invalidate at index addition or removalLibravatar Nguyễn Thái Ngọc Duy1-2/+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).

Most of the time the caller specifies to which destination variable the resulting index_state should be assigned by passing a non-NULL pointer in o->dst_index to receive that state, but for a caller that gives a NULL o->dst_index, the resulting index simply leaked.
