copies-rust: tokenize all paths into integer...
copies-rust: tokenize all paths into integer Copy information for each changesets tend to affect a small new number of path. However, each of these path might be handled a large number of time. Handling HgPathBuf (aka `Vec<u8>`) is expensive. Handling integer is cheap. With this patch we: - turn any input path into an integer "token" early, - do all the internal logic using such "token", - turn "token" back into path right before returning a result. This gives use a quite significant performance boost in our slower cases.

Mercurial for Windows



Welcome to Mercurial for Windows!




Mercurial is a command-line application. You must run it from
the Windows command prompt (or if you're hard core, a <a<br /> href="http://www.mingw.org/">MinGW shell).




Note: the standard http://www.mingw.org/">MinGW
msys startup script uses rxvt which has problems setting up
standard input and output. Running bash directly works
correctly.




For documentation, please visit the <a<br /> href="https://mercurial-scm.org/">Mercurial web site.
You can also download a free book, <a<br /> href="https://book.mercurial-scm.org/">Mercurial: The Definitive
Guide.




By default, Mercurial installs to C:\Program
Files\Mercurial
. The Mercurial command is called
hg.exe.



Testing Mercurial after you've installed it




The easiest way to check that Mercurial is installed properly is
to just type the following at the command prompt:




hg



This command should print a useful help message. If it does,
other Mercurial commands should work fine for you.



Configuration notes


Default editor



The default editor for commit messages is 'notepad'. You can set
the EDITOR (or HGEDITOR) environment variable
to specify your preference or set it in mercurial.ini:



[ui]
editor = whatever


Configuring a Merge program



It should be emphasized that Mercurial by itself doesn't attempt
to do a Merge at the file level, neither does it make any
attempt to Resolve the conflicts.




By default, Mercurial will use the merge program defined by the
HGMERGE environment variable, or uses the one defined
in the mercurial.ini file. (see <a<br /> href="https://mercurial-scm.org/wiki/MergeProgram">MergeProgram
on the Mercurial Wiki for more information)



Reporting problems




Before you report any problems, please consult the <a<br /> href="https://mercurial-scm.org/">Mercurial web site
and see if your question is already in our list of <a<br /> href="https://mercurial-scm.org/wiki/FAQ">Frequently
Answered Questions (the "FAQ").




If you cannot find an answer to your question, please feel free
to send mail to the Mercurial mailing list, at <a<br /> href="mailto:mercurial@mercurial-scm.org">mercurial@mercurial-scm.org.
Remember, the more useful information you include in your
report, the easier it will be for us to help you!




If you are IRC-savvy, that's usually the fastest way to get
help. Go to #mercurial on irc.freenode.net.
