path.c: remove home_config_paths()

2015-05-06T18:33:53Z

home_config_paths() combines distinct functionality already implemented by expand_user_path() and xdg_config_home(), and it also hard-codes the path ~/.gitconfig, which makes it unsuitable to use for other home config file paths. Since its use will just add unnecessary complexity to the code, remove it. Signed-off-by: Paul Tan Signed-off-by: Junio C Hamano

path.c: implement xdg_config_home()

2015-05-06T18:21:04Z

The XDG base dir spec[1] specifies that configuration files be stored in a subdirectory in $XDG_CONFIG_HOME. To construct such a configuration file path, home_config_paths() can be used. However, home_config_paths() combines distinct functionality: 1. Retrieve the home git config file path ~/.gitconfig 2. Construct the XDG config path of the file specified by `file`. This function was introduced in commit 21cf3227 ("read (but not write) from $XDG_CONFIG_HOME/git/config file"). While the intention of the function was to allow the home directory configuration file path and the xdg directory configuration file path to be retrieved with one function call, the hard-coding of the path ~/.gitconfig prevents it from being used for other configuration files. Furthermore, retrieving a file path relative to the user's home directory can be done with expand_user_path(). Hence, it can be seen that home_config_paths() introduces unnecessary complexity, especially if a user just wants to retrieve the xdg config file path. As such, implement a simpler function xdg_config_home() for constructing the XDG base dir spec configuration file path. This function, together with expand_user_path(), can replace all uses of home_config_paths().

* pt/enter-repo-comment-fix: enter_repo(): fix docs to match code

enter_repo(): fix docs to match code

2015-03-31T17:19:53Z

In b3256eb (standardize and improve lookup rules for external local repos), enter_repo() was modified to use a different precedence ordering of suffixes for DWIM of the repository path, and to ensure that the repository path is actually valid instead of just testing for existence. However, the documentation was not modified to reflect these changes. Fix the documentation to match the code. Documentation contributed by Jeff King.

path: add is_ntfs_dotgit() helper

2014-12-17T19:04:45Z

We do not allow paths with a ".git" component to be added to the index, as that would mean repository contents could overwrite our repository files. However, asking "is this path the same as .git" is not as simple as strcmp() on some filesystems. On NTFS (and FAT32), there exist so-called "short names" for backwards-compatibility: 8.3 compliant names that refer to the same files as their long names. As ".git" is not an 8.3 compliant name, a short name is generated automatically, typically "git~1". Depending on the Windows version, any combination of trailing spaces and periods are ignored, too, so that both "git~1." and ".git." still refer to the Git directory. The reason is that 8.3 stores file names shorter than 8 characters with trailing spaces. So literally, it does not matter for the short name whether it is padded with spaces or whether it is shorter than 8 characters, it is considered to be the exact same. The period is the separator between file name and file extension, and again, an empty extension consists just of spaces in 8.3 format. So technically, we would need only take care of the equivalent of this regex: (\.git {0,4}|git~1 {0,3})\. {0,3} However, there are indications that at least some Windows versions might be more lenient and accept arbitrary combinations of trailing spaces and periods and strip them out. So we're playing it real safe here. Besides, there can be little doubt about the intention behind using file names matching even the more lenient pattern specified above, therefore we should be fine with disallowing such patterns. Extra care is taken to catch names such as '.\\.git\\booh' because the backslash is marked as a directory separator only on Windows, and we want to use this new helper function also in fsck on other platforms. A big thank you goes to Ed Thomson and an unnamed Microsoft engineer for the detailed analysis performed to come up with the corresponding fixes for libgit2. This commit adds a function to detect whether a given file name can refer to the Git directory by mistake. Signed-off-by: Johannes Schindelin Signed-off-by: Junio C Hamano
