reachableroots: bail if integer object cannot be allocated
This patch also replaces Py_XDECREF() by Py_DECREF() because we known "val"
and "p" are not NULL.
BTW, we can eliminate some of these allocation and error handling of int objects
if the internal "seen" array has more information. For example,
enum { SEEN = 1, ROOT = 2, REACHABLE = 4 };
/* ... build ROOT mask from roots argument ... */
if (seen[revnum + 1] & ROOT) { /* instead of PySet_Contains(roots, val) */
>From my quick hack, it is 2x faster.

# 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-* import sys import os # 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.
