In case a configuration includes a key "include.path=" without any value, the generated configuration entry will have its value set to `NULL`. This is unexpected by the logic handling includes, and as soon as we try to calculate the included path we will unconditionally dereference that `NULL` pointer and thus segfault. Fix the issue by returning early in both `parse_include` and `parse_conditional_include` in case where the `file` argument is `NULL`. Add a test to avoid future regression. The issue has been found by the oss-fuzz project, issue 10810.

While our tests in config::include create a plethora of configuration files, most of them do not get removed at the end of each test. This can cause weird interactions with tests that are being run at a later stage if these later tests try to create files or directories with the same name as any of the created configuration files. Fix the issue by unlinking all created files at the end of these tests.

Now that we have abstracted away how to store and retrieve config entries, it became trivial to implement a new in-memory backend by making use of this. And thus we do so. This commit implements a new read-only in-memory backend that can parse a chunk of memory into a `git_config_backend` structure.

The header "config_file.h" has a list of inline-functions to access the contents of a config backend without directly messing with the struct's function pointers. While all these functions are called "git_config_file_*", they are in fact completely backend-agnostic and don't care whether it is a file or not. Rename all the function to instead be backend-agnostic versions called "git_config_backend_*" and rename the header to match.

C++ style comment ("//") are not specified by the ISO C90 standard and thus do not conform to it. While libgit2 aims to conform to C90, we did not enforce it until now, which is why quite a lot of these non-conforming comments have snuck into our codebase. Do a tree-wide conversion of all C++ style comments to the supported C style comments to allow us enforcing strict C90 compliance in a later commit.

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.

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 9e66590b (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.

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.

We put our repository in the temporary directory which makes macOS map the path into a virtual path. `realpath(3)` can resolve it and we do so during repository opening, but that makes its path have a different prefix from the sandbox path clar thinks we have. Resolve the sandbox path before putting it into the test config files so the paths match as expected.

While most parts of a configuration key are case-insensitive, we should still be case-preserving and write down whatever string the caller provided.

Next to the "gitdir" conditional for including other configuration files, there's also a "gitdir/i" conditional. In contrast to the former one, path matching with "gitdir/i" is done case-insensitively. This commit implements the case-insensitive condition.

Upstream git.git has implemented the ability to include other configuration files based on conditions. Right now, this only includes the ability to include a file based on the gitdir-location of the repository the currently parsed configuration file belongs to. This commit implements handling these conditional includes for the case-sensitive "gitdir" condition.
Patrick Steinhardt committed -
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`.

Modifying variables pulled in by an included file currently succeeds, but it doesn't actually do what one would expect, as refreshing the configuration will cause the values to reappear. As we are currently not really able to support this use case, we will instead just return an error for deleting and setting variables which were included via an include.
Patrick Steinhardt committed -
Right now, we have multiple call sites which initialize a `reader` structure. As the structure is only actually used inside of `config_read`, we can instead just move the reader inside of the `config_read` function. Instead, we can just pass in the configuration file into `config_read`, which eases code readability.
Patrick Steinhardt committed -
Currently, we only re-parse the top-level configuration file when it has changed itself. This can cause problems when an include is changed, as we were not updating all values correctly. Instead of conditionally reparsing only refreshed files, the logic becomes much clearer and easier to follow if we always re-parse the top-level configuration file when either the file itself or one of its included configuration files has changed on disk. This commit implements this logic. Note that this might impact performance in some cases, as we need to re-read all configuration files whenever any of the included files changed. It could increase performance to just re-parse include files which have actually changed, but this would compromise maintainability of the code without much gain. The only case where we will gain anything is when we actually use includes and when only these includes are updated, which will probably be quite an unusual scenario to actually be worthwhile to optimize.

On systems where we pull in our distributed version of the regex library, all tests in config::readonly fail. This error is actually quite interesting: the test suite is unable to find the declaration of `git_path_exists` and assumes it has a signature of `int git_path_exists(const char *)`. But actually, it has a `bool` return value. Due to this confusion, some wrong conversion is done by the compiler and the `cl_assert(!git_path_exists("file"))` checks erroneously fail, even when the function does in fact return the correct value. The error is actually introduced by 56893bb9 (cmake: consistently use TARGET_INCLUDE_DIRECTORIES if available, 2017-06-28), unfortunately introduced by myself. Due to the delayed addition of include directories, we will now find the "config.h" header inside of the "deps/regex" directory instead of inside the "src/" directory, where it should be. As such, we are missing definitions for the `git_config_file__ondisk` and `git_path_exists` symbols. The correct fix here would be to fix the order in which include search directories are added. But due to the current restructuring of CMakeBuild.txt, I'm refraining from doing so and delay the proper fix a bit. Instead, we paper over the issue by explicitly including "path.h" to fix its prototype. This ignores the issue that `git_config_file__ondisk` is undeclared, as its signature is correctly identified by the compiler.

We should notice that we are in the correct section to add. This is a cosmetic bug, since replacing any of these settings does work.

This special-casing ignores that we might have a locked file, so the hashtable does not represent the contents of the file we want to write. This causes multivar writes to overwrite entries instead of add to them when under lock. There is no need for this as the normal code-path will write to the file just fine, so simply get rid of it.

We currently use the timestamp in order to decide whether a config file has changed since we last read it. This scheme falls down if the file is written twice within the same second, as we fail to detect the file change after the first read in that second.

Untangle git_futils_mkdir from git_futils_mkdir_ext - the latter assumes that we own everything beneath the base, as if it were being called with a base of the repository or working directory, and is tailored towards checkout and ensuring that there is no bogosity beneath the base that must be cleaned up. This is (at best) slow and (at worst) unsafe in the larger context of a filesystem where we do not own things and cannot do things like unlink symlinks that are in our way.

This lock/unlock pair allows for the cller to lock a configuration file to avoid concurrent operations. It also allows for a transactional approach to updating a configuration file. If multiple updates must be made atomically, they can be done while the config is locked.
