43cbe6b7	2018-11-28T13:36:47	config: fix adding files if their parent directory is a file When we try to add a configuration file with `git_config_add_file_ondisk`, we treat nonexisting files as empty. We do this by performing a stat call, ignoring ENOENT errors. This works just fine in case the file or any of its parents simply does not exist, but there is also the case where any of the parent directories is not a directory, but a file. So e.g. trying to add a configuration file "/dev/null/.gitconfig" will fail, as `errno` will be ENOTDIR instead of ENOENT. Catch ENOTDIR in addition to ENOENT to fix the issue. Add a test that verifies we are able to add configuration files with such an invalid path file just fine.

6a15f657	2018-02-09T13:02:26	config_file: iterate over keys in the order they were added Currently, all configuration entries were only held in a string map, making iteration order mostly based on the hash of each entry's key. Now that we have extended the `diskfile_entries` structure by a list of config entries, we can effectively iterate through entries in the order they were added, though.
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.
529e873c	2017-05-23T11:51:00	config: pass repository when opening config files Our current configuration logic is completely oblivious of any repository, but only cares for actual file paths. Unfortunately, we are forced to break this assumption by the introduction of conditional includes, which are evaluated in the context of a repository. Right now, only one conditional exists with "gitdir:" -- it will only include the configuration if the current repository's git directory matches the value passed to "gitdir:". To support these conditionals, we have to break our API and make the repository available when opening a configuration file. This commit extends the `open` call of configuration backends to include another repository and adjusts existing code to have it available. This includes the user-visible functions `git_config_add_file_ondisk` and `git_config_add_backend`.

129022ee	2015-04-10T09:36:38	Fix checking of return value for regcomp. The regcomp function returns a non-zero value if compilation of a regular expression fails. In most places we only check for negative values, but positive values indicate an error, as well. Fix this tree-wide, fixing a segmentation fault when calling git_config_iterator_glob_new with an invalid regexp.
9a97f49e	2014-12-21T15:31:03	config: borrow refcounted references This changes the get_entry() method to return a refcounted version of the config entry, which you have to free when you're done. This allows us to avoid freeing the memory in which the entry is stored on a refresh, which may happen at any time for a live config. For this reason, get_string() has been forbidden on live configs and a new function get_string_buf() has been added, which stores the string in a git_buf which the user then owns. The functions which parse the string value takea advantage of the borrowing to parse safely and then release the entry.

25e0b157	2013-12-06T15:07:57	Remove converting user error to GIT_EUSER This changes the behavior of callbacks so that the callback error code is not converted into GIT_EUSER and instead we propagate the return value through to the caller. Instead of using the giterr_capture and giterr_restore functions, we now rely on all functions to pass back the return value from a callback. To avoid having a return value with no error message, the user can call the public giterr_set_str or some such function to set an error message. There is a new helper 'giterr_set_callback' that functions can invoke after making a callback which ensures that some error message was set in case the callback did not set one. In places where the sign of the callback return value is meaningful (e.g. positive to skip, negative to abort), only the negative values are returned back to the caller, obviously, since the other values allow for continuing the loop. The hardest parts of this were in the checkout code where positive return values were overloaded as meaningful values for checkout. I fixed this by adding an output parameter to many of the internal checkout functions and removing the overload. This added some code, but it is probably a better implementation. There is some funkiness in the network code where user provided callbacks could be returning a positive or a negative value and we want to rely on that to cancel the loop. There are still a couple places where an user error might get turned into GIT_EUSER there, I think, though none exercised by the tests.
