bdiff: improve worst case behavior by 100x.
on 5.8MB (244.000 lines) text file with similar lines, hash before
this change made diff against empty file take 75 seconds. this change
improves performance to 0.6 seconds. result is that clone of smallish
repo (137MB) with some files like this takes 1 minute instead of 10
minutes.
common case of diff is 10% slower now, probably because of worse cache
locality. but diff does not affect overall performance in common case
(less than 1% of runtime is in diff when it is working ok), so this
tradeoff looks good.

You must run it from the Windows command prompt (or if you're hard core, a <a href="http://www.mingw.org/">MinGW</a> shell).</p> <p><div class="indented"><i>Note: the standard <a href="http://www.mingw.org/">MinGW</a> msys startup script uses rxvt which has problems setting up standard input and output.

The Mercurial command is called <tt>hg.exe</tt>.</p> <h1>Testing Mercurial after you've installed it</h1> <p>The easiest way to check that Mercurial is installed properly is to just type the following at the command prompt:</p> <pre> hg </pre> <p>This command should print a useful help message. If it does, other Mercurial commands should work fine for you.</p> <h1>Configuration notes</h1> <p>The default editor for commit messages is 'vi'. You can set the EDITOR (or HGEDITOR) environment variable to specify your preference or set it in mercurial.ini:</p> <pre> [ui] editor = whatever </pre> <h1>Reporting problems</h1> <p>Before you report any problems, please consult the <a href="http://www.selenic.com/mercurial">Mercurial web site</a> and see if your question is already in our list of <a href="http://www.selenic.com/mercurial/wiki/index.cgi/FAQ">Frequently Answered Questions</a> (the "FAQ"). <p>If you cannot find an answer to your question, please feel free to send mail to the Mercurial mailing list, at <a href="mailto:mercurial@selenic.com">mercurial@selenic.com</a>. <b>Remember</b>, the more useful information you include in your report, the easier it will be for us to help you!</p> <p>If you are IRC-savvy, that's usually the fastest way to get help.
