2015-02-05config_buf_ungetc: warn when pushing back a random characterLibravatar Jeff King1-2/+6
Our config code simulates a stdio stream around a buffer, but our fake ungetc() does not behave quite like the real one. In particular, we only rewind the position by one character, but do _not_ actually put the character from the caller into position. It turns out that this does not matter, because we only ever push back the character we just read. In other words, such an assignment would be a noop. But because the function is called ungetc, and because it takes a character parameter, it is a mistake waiting to happen. Actually assigning the character into the buffer would be ideal, but our pointer is actually a "const" copy of the buffer. We do not know who the real owner of the buffer is in this code, and would not want to munge their contents. Instead, we can simply add an assertion that matches what the current caller does, and will let us know if new callers are added that violate the contract.

2015-02-05config: do not ungetc EOFLibravatar Jeff King1-1/+2
When we are parsing a config value, if we see a carriage return, we fgetc the next character to see if it is a line feed (in which case we silently drop the CR). If it isn't, we then ungetc the character, and take the literal CR. But we never check whether we in fact got a character at all. If the config file ends in CR, we will get EOF here, and try to ungetc EOF. This works OK for a real stdio stream. The ungetc returns an error, and the next fgetc will then return EOF again. However, our custom buffer-based stream is not so fortunate. It happily rewinds the position of the stream by one character, ignoring the fact that we fed it EOF. The next fgetc call returns the final CR again, over and over, and we end up in an infinite loop. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-01-13use xstrdup_or_null to replace ternary conditionalsLibravatar Jeff King1-1/+1
This replaces "x ? xstrdup(x) : NULL" with xstrdup_or_null(x). The change is fairly mechanical, with the exception of resolve_refdup, which can eliminate a temporary variable. There are still a few hits grepping for "?.*xstrdup", but these are of slightly different forms and cannot be converted (e.g., "x ? xstrdup(x->foo) : NULL").

2014-12-17read-cache: optionally disallow NTFS .git variantsLibravatar Johannes Schindelin1-0/+5
The point of disallowing ".git" in the index is that we would never want to accidentally overwrite files in the repository directory. But this means we need to respect the filesystem's idea of when two paths are equal. The prior commit added a helper to make such a comparison for NTFS and FAT32; let's use it in verify_path(). We make this check optional for two reasons: 1. It restricts the set of allowable filenames, which is unnecessary for people who are not on NTFS nor FAT32. In practice this probably doesn't matter, though, as the restricted names are rather obscure and almost certainly would never come up in practice. 2. It has a minor performance penalty for every path we insert into the index. This patch ties the check to the core.protectNTFS config option. Though this is expected to be most useful on Windows, we allow it to be set everywhere, as NTFS may be mounted on other platforms. The variable does default to on for Windows, though.

2014-10-01lockfile: change lock_file::filename into a strbufLibravatar Michael Haggerty1-7/+7
For now, we still make sure to allocate at least PATH_MAX characters for the strbuf because resolve_symlink() doesn't know how to expand the space for its return value. (That will be fixed in a moment.) Another alternative would be to just use a strbuf as scratch space in lock_file() but then store a pointer to the naked string in struct lock_file. But lock_file objects are often reused. By reusing the same strbuf, we can avoid having to reallocate the string most times when a lock_file object is reused.

2014-08-18make config --add behave correctly for empty and NULL valuesLibravatar Tanay Abhra1-1/+1
Currently if we have a config file like, [foo] baz bar = and we try something like, "git config --add foo.baz roll", Git will segfault. Moreover, for "git config --add foo.bar roll", it will overwrite the original value instead of appending after the existing empty value. The problem lies with the regexp used for simulating --add in `git_config_set_multivar_in_file()`, "^$", which in ideal case should not match with any string but is true for empty strings. Instead use a regexp like "a^" which can not be true for any string, empty or not. For removing the segfault add a check for NULL values in `matches()` in config.c.

2014-08-07rewrite git_config() to use the config-set APILibravatar Tanay Abhra1-8/+43
Of all the functions in `git_config*()` family, `git_config()` has the most invocations in the whole code base. Each `git_config()` invocation causes config file rereads which can be avoided using the config-set API. Use the config-set API to rewrite `git_config()` to use the config caching layer to avoid config file rereads on each invocation during a git process lifetime. First invocation constructs the cache, and after that for each successive invocation, `git_config()` feeds values from the config cache instead of rereading the configuration files.

A custom error message is also printed before dying, specified by the caller, which can be skipped if `err` argument is set to NULL. It has usage in non-callback based config value retrieval where we can raise an error and die if there is a semantic error.

2014-08-07change `git_config()` return value to voidLibravatar Tanay Abhra1-2/+14
Currently `git_config()` returns an integer signifying an error code. During rewrites of the function most of the code was shifted to `git_config_with_options()`. `git_config_with_options()` normally returns positive values if its `config_source` parameter is set as NULL, as most errors are fatal, and non-fatal potential errors are guarded by "if" statements that are entered only when no error is possible. Still a negative value can be returned in case of race condition between `access_or_die()` & `git_config_from_file()`. Also, all callers of `git_config()` ignore the return value except for one case in branch.c. Change `git_config()` return value to void and make it die if it receives a negative value from `git_config_with_options()`.

2014-07-29add `config_set` API for caching config-like filesLibravatar Tanay Abhra1-0/+274
Currently `git_config()` uses a callback mechanism and file rereads for config values. Due to this approach, it is not uncommon for the config files to be parsed several times during the run of a git program, with different callbacks picking out different variables useful to themselves. Add a `config_set`, that can be used to construct an in-memory cache for config-like files that the caller specifies (i.e., files like `.gitmodules`, `~/.gitconfig` etc.). Add two external functions `git_configset_get_value` and `git_configset_get_value_multi` for querying from the config sets. `git_configset_get_value` follows `last one wins` semantic (i.e. if there are multiple matches for the queried key in the files of the configset the value returned will be the last entry in `value_list`). `git_configset_get_value_multi` returns a list of values sorted in order of increasing priority (i.e. last match will be at the end of the list). Add type specific query functions like `git_configset_get_bool` and similar. Add a default `config_set`, `the_config_set` to cache all key-value pairs read from usual config files (repo specific .git/config, user wide ~/.gitconfig, XDG config and the global /etc/gitconfig). `the_config_set` is populated using `git_config()`. Add two external functions `git_config_get_value` and `git_config_get_value_multi` for querying in a non-callback manner from `the_config_set`. Also, add type specific query functions that are implemented as a thin wrapper around the `config_set` API.

It makes a copy of the string. Since we immediately parse the string into its single-character value, we only care about (1). And in fact (2) is a detriment, as it means we leak the copy.

2014-06-20refactor skip_prefix to return a booleanLibravatar Jeff King1-2/+1
The skip_prefix() function returns a pointer to the content past the prefix, or NULL if the prefix was not found. While this is nice and simple, in practice it makes it hard to use for two reasons: 1. When you want to conditionally skip or keep the string as-is, you have to introduce a temporary variable. For example: tmp = skip_prefix(buf, "foo"); if (tmp) buf = tmp; 2. It is verbose to check the outcome in a conditional, as you need extra parentheses to silence compiler warnings. For example: if ((cp = skip_prefix(buf, "foo")) /* do something with cp */ Both of these make it harder to use for long if-chains, and we tend to use starts_with() instead. However, the first line of "do something" is often to then skip forward in buf past the prefix, either using a magic constant or with an extra strlen(3) (which is generally computed at compile time, but means we are repeating ourselves). This patch refactors skip_prefix() to return a simple boolean, and to provide the pointer value as an out-parameter. If the prefix is not found, the out-parameter is untouched.
