b8a67eda	2018-07-22T23:47:12	Fix a double-free in config parsing
83b5f161	2017-11-12T14:09:24	config_parse: always sanitize out-parameters in `parse_variable` The `parse_variable` function has two out parameters `var_name` and `var_value`. Currently, those are not being sanitized to `NULL`. when. any error happens inside of the `parse_variable` function. Fix that. While at it, the coding style is improved to match our usual coding practices more closely.
e51e29e8	2017-11-12T13:59:47	config_parse: have `git_config_parse` own entry value and name The function `git_config_parse` uses several callbacks to pass data along to the caller as it parses the file. One design shortcoming here is that strings passed to those callbacks are expected to be freed by them, which is really confusing. Fix the issue by changing memory ownership here. Instead of expecting the `on_variable` callbacks to free memory for `git_config_parse`, just do it inside of `git_config_parse`. While this obviously requires a bit more memory allocation churn due to having to copy both name and value at some places, this shouldn't be too much of a burden.

ba4faf6e	2018-02-08T17:15:33	buf_text: remove `offset` parameter of BOM detection function The function to detect a BOM takes an offset where it shall look for a BOM. No caller uses that, and searching for the BOM in the middle of a buffer seems to be very unlikely, as a BOM should only ever exist at file start. Remove the parameter, as it has already caused confusion due to its weirdness.
2eea5f1c	2018-02-08T10:27:31	config_parse: fix reading files with BOM The function `skip_bom` is being used to detect and skip BOM marks previously to parsing a configuration file. To do so, it simply uses `git_buf_text_detect_bom`. But since the refactoring to use the parser interface in commit 9e66590bd (config_parse: use common parser interface, 2017-07-21), the BOM detection was actually broken. The issue stems from a misunderstanding of `git_buf_text_detect_bom`. It was assumed that its third parameter limits the length of the character sequence that is to be analyzed, while in fact it was an offset at which we want to detect the BOM. Fix the parameter to be `0` instead of the buffer length, as we always want to check the beginning of the configuration file.
848153f3	2018-02-08T10:02:29	config_parse: handle empty lines with CRLF Currently, the configuration parser will fail reading empty lines with just an CRLF-style line ending. Special-case the '\r' character in order to handle it the same as Unix-style line endings. Add tests to spot this regression in the future.
5340ca77	2018-02-08T09:31:51	config_parse: add comment to clarify logic getting next character Upon each line, the configuration parser tries to get either the first non-whitespace character or the first whitespace character, in case there is no non-whitespace character. The logic handling this looks rather odd and doesn't immediately convey this meaning, so add a comment to clarify what happens.
9e66590b	2017-07-21T13:01:43	config_parse: use common parser interface As the config parser is now cleanly separated from the config file code, we can easily refactor the code and make use of the common parser module. This removes quite a lot of duplicated functionality previously used for handling the actual parser state and replaces it with the generic interface provided by the parser context.
1953c68b	2017-11-11T17:12:31	config_file: split out module to parse config files The configuration file code grew quite big and intermingles both actual configuration logic as well as the parsing logic of the configuration syntax. This makes it hard to refactor the parsing logic on its own and convert it to make use of our new parsing context module. Refactor the code and split it up into two parts. The config file code will only handle actual handling of configuration files, includes and writing new files. The newly created config parser module is then only responsible for parsing the actual contents of a configuration file, leaving everything else to callbacks provided to its provided function `git_config_parse`.
