Cover letter [PATCH v2 0/1] Expand abbreviated filters
NOTE: this patch is based on top of md/list-objects-filter-by-depth
Currently, git clients pass filter specs verbatim over the network and to subprocesses. We support various scaling suffixes for parameters on these limits (via git_parse_ulong()), but other implementations may not support the same suffixes. It would be better to only pass fully- expanded numbers in this case, and keep the expansion logic completely on the client side.
This patch updates the protocol-v2 doc to specify that clients SHOULD expand abbreviations in filter specifications before passing them to other processes. It adds a new function "expand_list_objects_filter_spec()" in list-objects-filter-options.c that implements the expansion logic, and updates users of the filter_spec field to instead expand the spec first.
Changes since V1:
* Changed "MUST" to "SHOULD" in protocol-v2.txt
* Noted specific suffixes that receivers SHOULD accept
