# Helper script used for generating history and working copy files and content. # The file's name corresponds to its history. The number of changesets can # be specified on the command line. With 2 changesets, files with names like # content1_content2_content1-untracked are generated. The first two filename # segments describe the contents in the two changesets. The third segment # ("content1-untracked") describes the state in the working copy, i.e. # the file has content "content1" and is untracked (since it was previously # tracked, it has been forgotten). # # This script generates the filenames and their content, but it's up to the # caller to tell hg about the state. # # There are two subcommands: # filelist <numchangesets> # state <numchangesets> (<changeset>|wc) # # Typical usage: # # $ python $TESTDIR/generate-working-copy-states.py state 2 1 # $ hg addremove --similarity 0 # $ hg commit -m 'first' # # $ python $TESTDIR/generate-working-copy-states.py state 2 1 # $ hg addremove --similarity 0 # $ hg commit -m 'second' # # $ python $TESTDIR/generate-working-copy-states.py state 2 wc # $ hg addremove --similarity 0 # $ hg forget *_*_*-untracked # $ rm *_*_missing-* from __future__ import absolute_import, print_function import os import sys # Generates pairs of (filename, contents), where 'contents' is a list # describing the file's content at each revision (or in the working copy). # At each revision, it is either None or the file's actual content.
