* convert trivial cases to FLEX_ARRAY macrosJeff King2016-02-22
| | | | | | | | | | Using FLEX_ARRAY macros reduces the amount of manual computation size we have to do. It also ensures we don't overflow size_t, and it makes sure we write the same number of bytes that we allocated.

* convert trivial cases to ALLOC_ARRAYJeff King2016-02-22
| | | | | | | | | | | | | | | 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.

* memoize common git-path "constant" filesJeff King2015-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the most common uses of git_path() is to pass a constant, like git_path("MERGE_MSG"). This has two drawbacks: 1. The return value is a static buffer, and the lifetime is dependent on other calls to git_path, etc. 2. There's no compile-time checking of the pathname. This is OK for a one-off (after all, we have to spell it correctly at least once), but many of these constant strings appear throughout the code. This patch introduces a series of functions to "memoize" these strings, which are essentially globals for the lifetime of the program. We compute the value once, take ownership of the buffer, and return the cached value for subsequent calls. cache.h provides a helper macro for defining these functions as one-liners, and defines a few common ones for global use. Using a macro is a little bit gross, but it does nicely document the purpose of the functions. If we need to touch them all later (e.g., because we learned how to change the git_dir variable at runtime, and need to invalidate all of the stored values), it will be much easier to have the complete list. Note that the shared-global functions have separate, manual declarations. We could do something clever with the macros (e.g., expand it to a declaration in some places, and a declaration _and_ a definition in path.c). But there aren't that many, and it's probably better to stay away from too-magical macros. Likewise, if we abandon the C preprocessor in favor of generating these with a script, we could get much fancier. E.g., normalizing "FOO/BAR-BAZ" into "git_path_foo_bar_baz". But the small amount of saved typing is probably not worth the resulting confusion to readers who want to grep for the function's definition.

* | attr: avoid heavy work when we know the specified attr is not definedNguyễn Thái Ngọc Duy2014-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we have never seen attr 'X' in any .gitattributes file we have examined so far, we can be sure that 'X' is not defined. So no need to go over all the attr stack to look for attr 'X'. This is the purpose behind this new field maybe_real. This optimization breaks down if macros are involved because we can't know for sure what macro would expand to 'X' at attr parsing time. But if we go the pessimistic way and assume all macros are expanded, we hit the builtin "binary" macro. At least the "diff" attr defined in this macro will disable this optimization for git-grep. So we wait until any attr lines _may_ reference to a macro before we turn this off. In git.git, this reduces the number of fill_one() call for "git grep abcdefghi" from ~5348 to 2955. The optimization stops when it reads t/.gitattributes, which uses 'binary' macro. We could probably reduce it further by limiting the 'binary' reference to t/ and subdirs only in this case. "git grep" is actually a good example to justify this patch. The command checks "diff" attribute on every file. People usually don't define this attribute. But they pay the attr lookup penalty anyway without this patch, proportional to the number of attr lines they have in repo.

* | attr: do not attempt to expand when we know it's not a macroNguyễn Thái Ngọc Duy2014-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Keep track of all recognized macros in the new "maybe_macro" field. If this field is true, it _may_ be a macro (depending on what's in the current attr stack). But if the field is false, it's definitely not a macro, no need to go through the whole attr stack in macroexpand_one() to search for one. Without this, "git grep abcdefghi" on git.git hits the inner loop in macroexpand_one() 2481 times. With this, it's 66 times.

A MUSTBEDIR pattern "element/" is represented as a counted string <"element/", 7> and this must match match pathname "element/". Because match_basename() and match_pathname() want to see pathname "element" to match against the pattern <"element/", 7>, reduce the length of the path to exclude the trailing slash when calling these functions.

The docs, however, always said The rules how the pattern matches paths are the same as in `.gitignore` files; see linkgit:gitignore[5]. By those rules, leading '!' means pattern negation. So 82dce99 correctly determined that this kind of line makes no sense and should be disallowed. However, users who actually had a rule for files starting with a '!' are in a bad position: before 82dce99 '!' matched that literal character, so it is conceivable that users have .gitattributes with such lines in them. After 82dce99 the unescaped version was disallowed in such a way that git outright refuses to run(!) most commands in the presence of such a .gitattributes. It therefore becomes very hard to fix, let alone work with, such repositories. Let's at least allow the users to fix their repos: change the fatal error into a warning.

This function expects the directory without the trailing slash (as "origin" field in match_attr struct is without the trailing slash). find_basename() includes the trailing slash and confuses push/pop algorithm. Consider path = "abc/def" and the push down code: while (1) { len = strlen(attr_stack->origin); if (dirlen <= len) break; cp = memchr(path + len + 1, '/', dirlen - len - 1); if (!cp) cp = path + dirlen; dirlen is 4, not 3, without this patch. So when attr_stack->origin is "abc", it'll miss the exit condition because 4 <= 3 is wrong. It'll then try to push "abc/" down the attr stack (because "cp" would be NULL). So we have both "abc" and "abc/" in the stack. Next time when "abc/ghi" is checked, "abc/" is popped out because of the off-by-one dirlen, only to be pushed back in again by the above code. This repeats for all files in the same directory. Which means at least one failed open syscall per file, or more if .gitattributes exists.

We however sometimes have to attempt to open the .gitattributes file from a directory that does not exist in the commit that is currently checked out.

* | warn_on_inaccessible(): a helper to warn on inaccessible pathsJunio C Hamano2012-08-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous series introduced warnings to multiple places, but it could become tiring to see the warning on the same path over and over again during a single run of Git. Making just one function responsible for issuing this warning, we could later choose to keep track of which paths we issued a warning (it would involve a hash table of paths after running them through real_path() or something) in order to reduce noise. Right now we do not know if the noise reduction is necessary, but it still would be a good code reduction/sharing anyway. Signed-off-by: Junio C Hamano <gitster@pobox.com>
* | attr: warn on inaccessible attribute filesJeff King2012-08-21
| | | | | | | | | | | | | | | | | | | | Just like config and gitignore files, we silently ignore missing or inaccessible attribute files. An existent but inaccessible file is probably a configuration error, so let's warn the user. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* | attr: make sure we have an xdg path before using itJeff King2012-07-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we don't have a core.attributesfile configured, we fall back to checking XDG config, which is usually $HOME/.config/git/attributes. However, if $HOME is unset, then home_config_paths will return NULL, and we end up calling fopen(NULL). Depending on your system, this may or may not cause the accompanying test to fail (e.g., on Linux and glibc, the address will go straight to open, which will return EFAULT). However, valgrind will reliably notice the error. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | This function frees the individual "struct match_attr"s we have allocated, but forgot to free the array holding their pointers, leading to a minor memory leak (but it can add up after checking attributes for paths in many directories).
