cleanup of revlog.group when repository is local revlog.group cached every chunk from the revlog, the behaviour was needed to minimize the roundtrip with old-http. We now cache the revlog data ~4MB at a time. The memory used server side when pulling goes down to 35Mo maximum whereas without the patch more than 160Mo was used when cloning the linux kernel repository. The time used by cloning is higher mainly because of the check in revlog.revision. before 110.25user 20.90system 2:52.00elapsed 76%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+708707minor)pagefaults 0swaps after 117.56user 18.86system 2:50.43elapsed 80%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+748366minor)pagefaults 0swaps

Mercurial's documentation is currently kept in ASCIIDOC format, which
is a simple plain text format that's easy to read and edit. It's also
convertible to a variety of other formats including standard UNIX man
page format and HTML.

To do this, you'll need to install ASCIIDOC:

 http://www.methods.co.nz/asciidoc/

To generate the man page:

 asciidoc -d manpage -b docbook hg.1.txt
 xmlto man hg.1.xml

To display:

 groff -mandoc -Tascii hg.1 | more

To create the html page (without stylesheets):

 asciidoc -b html hg.1.txt
