"""Builds rsync's filter options to send |source_paths|.
Builds a list of command line arguments for rsync's filter option
to send |source_paths| excluding |exclude_paths|.
The rsync's filter is a bit complicated.
Note:
- The order of the rule is important. Earlier rule is stronger than
rest.
- In the rule, paths beginning with '/' matches with the paths relative
to the copy source directory, otherwise it matches any component.
For example, assuming the copy source directory is "source",
"*.pyc" matches any files (or directories) whose name ends with .pyc,
such as "source/test.pyc", "source/dir1/test.pyc", "source/dir2/main.pyc"
and so on.
- rsync traverses the paths recursively from top to bottom, and checks
filters for each path. So, if a file needs to be sent, all its ancestors
must be included.
E.g., if a/b/c/d needs to be sent;
--inlucde /a --include /a/b --include /a/b/c --include /a/b/c/d
must be set.
- If a directory path matches with the include pattern, all its descendants
will be sent. So, in above case, /a/*, /a/b/*, /a/b/c* and all their
descendants will be also sent. To avoid such a situation, this function
also adds;
--exclude /a/* --exclude /a/b/* --exclude /a/b/c/* --exclude /*
after include rules (as weaker rules).
Args:
source_paths: a list of paths for files and directories to be sent.
Please see rsync()'s docstring for more details.
exclude_paths: a list of paths for files and directories to be
excluded from the list of sending paths.
Returns: a list of filter command line arguments for rsync.
