2016-02-22use st_add and st_mult for allocation size computationLibravatar Jeff King1-1/+1
If our size computation overflows size_t, we may allocate a much smaller buffer than we expected and overflow it. It's probably impossible to trigger an overflow in most of these sites in practice, but it is easy enough convert their additions and multiplications into overflow-checking variants. This may be fixing real bugs, and it makes auditing the code easier. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-02-22convert trivial cases to ALLOC_ARRAYLibravatar Jeff King1-1/+1
Each of these cases can be converted to use ALLOC_ARRAY or REALLOC_ARRAY, which has two advantages: 1. It automatically checks the array-size multiplication for overflow. 2. It always uses sizeof(*array) for the element-size, so that it can never go out of sync with the declared type of the array.

2016-01-25clean: make is_git_repository a public functionLibravatar Jeff King1-25/+1
We have always had is_git_directory(), for looking at a specific directory to see if it contains a git repo. In 0179ca7 (clean: improve performance when removing lots of directories, 2015-06-15), we added is_git_repository() which checks for a non-bare repository by looking at its ".git" entry. However, the fix in 0179ca7 needs to be applied other places, too. Let's make this new helper globally available. We need to give it a better name, though, to avoid confusion with is_git_directory(). This patch does that, documents both functions with a comment to reduce confusion, and removes the clean-specific references in the comments.

2015-10-05use strbuf_complete to conditionally append slashLibravatar Jeff King1-4/+2
When working with paths in strbufs, we frequently want to ensure that a directory contains a trailing slash before appending to it. We can shorten this code (and make the intent more obvious) by calling strbuf_complete. Most of these cases are trivially identical conversions, but there are two things to note: - in a few cases we did not check that the strbuf is non-empty (which would lead to an out-of-bounds memory access). These were generally not triggerable in practice, either from earlier assertions, or typically because we would have just fed the strbuf to opendir(), which would choke on an empty path. - in a few cases we indexed the buffer with "original_len" or similar, rather than the current sb->len, and it is not immediately obvious from the diff that they are the same. In all of these cases, I manually verified that the strbuf does not change between the assignment and the strbuf_complete call. This does not convert cases which look like: if (sb->len && !is_dir_sep(sb->buf[sb->len - 1])) strbuf_addch(sb, '/'); as those are obviously semantically different. Some of these cases arguably should be doing that, but that is out of scope for this change, which aims purely for cleanup with no behavior change (and at least it will make such sites easier to find and examine in the future, as we can grep for strbuf_complete).

2015-06-15clean: improve performance when removing lots of directoriesLibravatar Erik Elfström1-4/+26
"git clean" uses resolve_gitlink_ref() to check for the presence of nested git repositories, but it has the drawback of creating a ref_cache entry for every directory that should potentially be cleaned. The linear search through the ref_cache list causes a massive performance hit for large number of directories. Modify clean.c:remove_dirs to use setup.c:is_git_directory and setup.c:read_gitfile_gently instead. Both these functions will open files and parse contents when they find something that looks like a git repository. This is ok from a performance standpoint since finding repository candidates should be comparatively rare. Using is_git_directory and read_gitfile_gently should give a more standardized check for what is and what isn't a git repository but also gives three behavioral changes. The first change is that we will now detect and avoid cleaning empty nested git repositories (only init run). This is desirable. Second, we will no longer die when cleaning a file named ".git" with garbage content (it will be cleaned instead). This is also desirable. The last change is that we will detect and avoid cleaning empty bare repositories that have been placed in a directory named ".git". This is not desirable but should have no real user impact since we already fail to clean non-empty bare repositories in the same scenario. This is thus deemed acceptable. On top of this we add some extra precautions. If read_gitfile_gently fails to open the git file, read the git file or verify the path in the git file we assume that the path with the git file is a valid repository and avoid cleaning. Update t7300 to reflect these changes in behavior. The time to clean an untracked directory containing 100000 sub directories went from 61s to 1.7s after this change.

2014-10-14color_parse: do not mention variable name in error messageLibravatar Jeff King1-2/+1
Originally the color-parsing function was used only for config variables. It made sense to pass the variable name so that the die() message could be something like: $ git -c color.branch.plain=bogus branch fatal: bad color value 'bogus' for variable 'color.branch.plain' These days we call it in other contexts, and the resulting error messages are a little confusing: $ git log --pretty='%C(bogus)' fatal: bad color value 'bogus' for variable '--pretty format' $ git config --get-color foo.bar bogus fatal: bad color value 'bogus' for variable 'command line' This patch teaches color_parse to complain only about the value, and then return an error code. Config callers can then propagate that up to the config parser, which mentions the variable name. Other callers can provide a custom message. After this patch these three cases now look like: $ git -c color.branch.plain=bogus branch error: invalid color value: bogus fatal: unable to parse 'color.branch.plain' from command-line config $ git log --pretty='%C(bogus)' error: invalid color value: bogus fatal: unable to parse --pretty format $ git config --get-color foo.bar bogus error: invalid color value: bogus fatal: unable to parse default color value Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

When we get a list of paths from read_directory, we further prune it to create the final list of items to remove. The code paths for directories and non-directories repeat the same "add to list" code. This patch restructures the code so that we don't repeat ourselves. Also, by following a "if (condition) continue" pattern like the pathspec check above, it makes it more obvious that the conditional is about excluding directories under certain circumstances.

2014-03-11clean: respect pathspecs with "-d"Libravatar Jeff King1-2/+3
git-clean uses read_directory to fill in a `struct dir` with potential hits. However, read_directory does not actually check against our pathspec. It uses a simplified version that may turn up false positives. As a result, we need to check that any hits match our pathspec. We do so reliably for non-directories. For directories, if "-d" is not given we check that the pathspec matched exactly (i.e., we are even stricter, and require an explicit "git clean foo" to clean "foo/"). But if "-d" is given, rather than relaxing the exact match to allow a recursive match, we do not check the pathspec at all.

2014-02-24clean: replace match_pathspec() with dir_path_match()Libravatar Nguyễn Thái Ngọc Duy1-2/+1
This instance was left out when many match_pathspec() call sites that take input from dir_entry were converted to dir_path_match() because it passed a path with the trailing slash stripped out to match_pathspec() while the others did not. Stripping for all call sites back then would be a regression because match_pathspec() did not know how to match pathspec foo/ against _directory_ foo (the stripped version of path "foo/"). match_pathspec() knows how to do it now. And dir_path_match() strips the trailing slash also. Use the new function, because the stripping code is removed in the next patch.

2014-02-24pathspec: pass directory indicator to match_pathspec_item()Libravatar Nguyễn Thái Ngọc Duy1-1/+1
This patch activates the DO_MATCH_DIRECTORY code in m_p_i(), which makes "git diff HEAD submodule/" and "git diff HEAD submodule" produce the same output. Previously only the version without trailing slash returns the difference (if any). That's the effect of new ce_path_match(). dir_path_match() is not executed by the new tests. And it should not introduce regressions. Previously if path "dir/" is passed in with pathspec "dir/", they obviously match. With new dir_path_match(), the path becomes _directory_ "dir" vs pathspec "dir/", which is not executed by the old code path in m_p_i(). The new code path is executed and produces the same result. The other case is pathspec "dir" and path "dir/" is now turned to "dir" (with DO_MATCH_DIRECTORY). Still the same result before or after the patch. So why change?

2013-07-09Convert "struct cache_entry *" to "const ..." wherever possibleLibravatar Nguyễn Thái Ngọc Duy1-1/+1
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.
