comparison mercurial/posix.py @ 15011:5e44e4b3a0a3

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
util: move copymode into posix.py and windows.py reducing it to a NOP on Windows. This eliminates a pointless stat call on Windows and reduces the risk of interferring with other processes (e.g. AV-scanners, file change watchers).
