comparison src/org/tmatesoft/hg/repo/HgWorkingCopyStatusCollector.java @ 694:7efabe0cddcf

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Speed up (a) file rename history to minimize file reads; (b) file.isCopy(int) to read metadata for few revisions at once (use pattern assumes earlier revisions are likely to be queried, too); (c) HgIgnore.isIgnored by caching matched initial fragments (to substitute more expensive Matcher.matches with cheaper HashMap.contains)
