test-dirstate: remove test with date larger than 32 bit When running on a 32bit system or with a touch command that only accepts 32bit dates, the following happened: $ touch -t 250001011200 a touch: invalid date format `250001011200'

bookmarks: deactivate current bookmark if no name is given f57f891eb88e added this help text to hg bookmark: If no NAME is given, the current active bookmark will be marked inactive. But that was never actually the case. Originally spotted by Idan Kamara <idankk86@gmail.com>.

contrib: add a commit synthesizer for reproducing scaling problems This adds two new commands: - analyze examines an existing repo and writes out a statistical description of its properties that contains no identifying information. - synthesize creates new commits based on the description generated by analyze. The intention is that a repo constructed using synthesize will have properties that are vaguely statistically similar to the originating repo, but entirely random content. This can be useful for forecasting performance as a repo grows, and for developers who want to find bottlenecks in proprietary repos to which they do not have access.

dirstate: handle large dates and times with masking (issue2608) Dates and times that are outside the 31-bit signed range are now compared modulo 2^31. This should prevent it from behaving badly with very large files or corrupt dates while still having a high probability of detecting changes.
