Summary: Perforce client support a view. A view maps a server side path to a client side path, e.g.: the view '//depot/A/B/... //myclient/foo/...' maps every file in //depot/A/B/ on the server side to a local checkout foo/ inside the root for checkouts defined for the client 'myclient'. We are using §p4 where§ to support these mappings. We do the mapping inside the FileImporter at the moment as this runs nicely in parallel. It's a bit hacky but get's the job done. We use this mostly to ommit the common prefix //depot/... and remove branch indicators such as Main. So in our case a view looks like //depot/Software/OculusSDK/PC/Main... //client/Software/OculusSDK/PC/... resulting in a file //depot/Software/OculusSDK/PC/Main/test.txt being imported as Software/OculusSDK/PC/test.xt Test Plan: rt test-p4* Reviewers: #sourcecontrol, #idi, ikostia Reviewed By: ikostia Subscribers: ikostia, durham, mjpieters Differential Revision: https://phabricator.intern.facebook.com/D4913483 Signature: t1:4913483:1492702356:b97b691343b8a1d52940445934730b31d411db4c
