[PATCH v3] builtin/remote.c: teach `-v` to list filters for promisor remotes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Abhradeep Chakraborty <chakrabortyabhradeep79@xxxxxxxxx>

`git remote -v` (`--verbose`) lists down the names of remotes along with
their urls. It would be beneficial for users to also specify the filter
types for promisor remotes. Something like this -

	origin	remote-url (fetch) [blob:none]
	origin	remote-url (push)

Teach `git remote -v` to also specify the filters for promisor remotes.

    builtin/remote.c: teach -v to list filters for promisor remotes
    
    Fixes #1211 [1]
    
    In the previous version, documentation is updated (describing the
    proposed change) and url_buf is renamed into remote_info_buf. In this
    varsion, some more test cases are added and broken indentations are
    fixed.
