2017-03-17ls-files: fix bug when recursing with relative pathspecLibravatar Brandon Williams1-0/+39
When using the --recurse-submodules flag with a relative pathspec which includes "..", an error is produced inside the child process spawned for a submodule. When creating the pathspec struct in the child, the ".." is interpreted to mean "go up a directory" which causes an error stating that the path ".." is outside of the repository. While it is true that ".." is outside the scope of the submodule, it is confusing to a user who originally invoked the command where ".." was indeed still inside the scope of the superproject. Since the child process launched for the submodule has some context that it is operating underneath a superproject, this error could be avoided. This patch fixes the bug by passing the 'prefix' to the child process. Now each child process that works on a submodule has two points of reference to the superproject: (1) the 'super_prefix' which is the path from the root of the superproject down to root of the submodule and (2) the 'prefix' which is the path from the root of the superproject down to the directory where the user invoked the git command. With these two pieces of information a child process can correctly interpret the pathspecs provided by the user as well as being able to properly format its output relative to the directory the user invoked the original command from.

2016-10-10ls-files: add pathspec matching for submodulesLibravatar Brandon Williams1-3/+105
Pathspecs can be a bit tricky when trying to apply them to submodules. The main challenge is that the pathspecs will be with respect to the superproject and not with respect to paths in the submodule. The approach this patch takes is to pass in the identical pathspec from the superproject to the submodule in addition to the submodule-prefix, which is the path from the root of the superproject to the submodule, and then we can compare an entry in the submodule prepended with the submodule-prefix to the pathspec in order to determine if there is a match. This patch also permits the pathspec logic to perform a prefix match against submodules since a pathspec could refer to a file inside of a submodule. Due to limitations in the wildmatch logic, a prefix match is only done literally. If any wildcard character is encountered we'll simply punt and produce a false positive match. More accurate matching will be done once inside the submodule. This is due to the superproject not knowing what files could exist in the submodule.

2016-10-10ls-files: optionally recurse into submodulesLibravatar Brandon Williams1-0/+100
Allow ls-files to recognize submodules in order to retrieve a list of files from a repository's submodules. This is done by forking off a process to recursively call ls-files on all submodules. Use top-level --super-prefix option to pass a path to the submodule which it can use to prepend to output or pathspec matching logic.
