cleanup of revlog.group when repository is local...
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. The patch export the information that the repository is local or not from the repository object down to the revlog. Then it uses the workaround for old-http only if the repository is non-local. The memory used server side when pulling goes down to less than 30Mo maximum whereas without the patch more than 160Mo was used when cloning the linux kernel repository. The time used by cloning is roughly the same (although some caching could be implemented if needed): before 110.25user 20.90system 2:52.00elapsed 76%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+708707minor)pagefaults 0swaps after 112.85user 22.98system 2:50.66elapsed 79%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (0major+862862minor)pagefaults 0swaps

MERCURIAL QUICK-START

Setting up Mercurial:

Note: some distributions fails to include bits of distutils by
default, you'll need python-dev to install. You'll also need a C
compiler and a 3-way merge tool like merge, tkdiff, or kdiff3.

First, unpack the source:

$ tar xvzf mercurial-<ver>.tar.gz
$ cd mercurial-<ver>

To install system-wide:

$ python setup.py install # change python to python2.3 if 2.2 is default

To install in your home directory (~/bin and ~/lib, actually), run:

$ python2.3 setup.py install --home=~
$ export PYTHONPATH=${HOME}/lib/python # (or lib64/ on some systems)
$ export PATH=${HOME}/bin:$PATH # add these to your .bashrc

And finally:

$ hg # test installation, show help

If you get complaints about missing modules, you probably haven't set
PYTHONPATH correctly.

Setting up a Mercurial project:

$ cd project/
$ hg init # creates .hg
$ hg addremove # add all unknown files and remove all missing files
$ hg commit # commit all changes, edit changelog entry

Mercurial will look for a file named .hgignore in the root of your
repository which contains a set of regular expressions to ignore in
file paths.

Branching and merging:

$ hg clone linux linux-work # create a new branch
$ cd linux-work
$ <make changes>
$ hg commit
$ cd ../linux
$ hg pull ../linux-work # pull changesets from linux-work
$ hg update -m # merge the new tip from linux-work into
# our working directory
$ hg commit # commit the result of the merge

Importing patches:

Fast:
$ patch < ../p/foo.patch
$ hg addremove
$ hg commit

Faster:
$ patch < ../p/foo.patch
$ hg commit `lsdiff -p1 ../p/foo.patch`

Fastest:
$ cat ../p/patchlist | xargs hg import -p1 -b ../p

Exporting a patch:

(make changes)
$ hg commit
$ hg tip
28237:747a537bd090880c29eae861df4d81b245aa0190
$ hg export 28237 > foo.patch # export changeset 28237

Network support:

# pull from the primary Mercurial repo
foo$ hg clone http://selenic.com/hg/
foo$ cd hg

# export your current repo via HTTP with browsable interface
foo$ hg serve -n "My repo" -p 80

# pushing changes to a remote repo with SSH
foo$ hg push ssh://user@example.com/~/hg/

# merge changes from a remote machine
bar$ hg pull http://foo/
bar$ hg update -m # merge changes into your working directory

# Set up a CGI server on your webserver
foo$ cp hgweb.cgi ~/public_html/hg/index.cgi
foo$ emacs ~/public_html/hg/index.cgi # adjust the defaults
