remotephase: fast path newheads computation in simple case (issue5964)...

remotephase: fast path newheads computation in simple case (issue5964) Changeset fixed the logic of `phases.newheads` but greatly regressed its performance (up to many order of magnitude). The first step to fix the regression is to exit early when there is no work to do. If there are no heads to filter or not roots to filter them, we don't have to do any work. This fixes the regression when talking to an all public changeset. The performance is even better than before. pypy, compared to an all public repo ------------------------------------ 8eeed92475d5: 0.005758 seconds 88efb7d6bcb6: 0.602517 seconds (x104) this code: 0.001508 seconds (-74% from base) mercurial compared to an all public repo ---------------------------------------- 8eeed92475d5: 0.000577 seconds 88efb7d6bcb6: 0.185316 seconds (x321) this code: 0.000150 seconds (-74% from base) The performance of newheads, when actual computations are required, is fixed in the next changeset.

      # Description

      # -----------

      # This script generates a tcsh source file to support completion

      # of Mercurial commands and options.

      #

      # Instruction:

      # -----------

      # Run this script to generate the tcsh source file, and source

      # the file to add command completion support for Mercurial.

      #

      # If FILE is not specified, tcsh_completion will be generated.

      #

      # Bugs:

      # ----

      # 1. command specific options are not supported

      # 2. hg commands must be specified immediately after 'hg'.
