Mercurial is a distributed source control management tool similar to Git and Bazaar. Mercurial is written in Python and is used by projects such as Mozilla and Vim.
This package is known to build and work properly using an LFS-9.0 platform.

User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/mercurial
Build Mercurial by issuing the following command:
make build
To build the documentation (requires docutils-0.15), issue:
sed -i '/runrst/s/N)/N)3/' doc/Makefile && 2to3-3.7 -w doc/hgmanpage.py && make doc
To run the test suite, issue:
rm -rf tests/tmp &&
TESTFLAGS="-j<N> --tmpdir tmp --blacklist blacklists/fsmonitor --blacklist blacklists/linux-vfat" make check
where <N> is an
integer between one and the number of ( processor X threads ),
inclusive. In order to investigate any apparently failing tests,
you may use the run-tests.py script. To see the
almost forty switches, some of them very useful, issue tests/run-tests.py --help.
Running the following commands, you will execute only the tests
that failed before:
pushd tests && rm -rf tmp && ./run-tests.py --tmpdir tmp test-gpg.t popd
Normally, the previous failures will be confirmed. However, if you add the switch "--debug" before "--tmpdir", and run again, some failures are gone, which seems to be a problem with the test suite. If this happens, normally, from now on, there will be no more such failures whether you use the debug switch or not. Three tests, test-alias.t, test-install.t, and test-bundle2-exchange.t (intermittently), are known to fail.
An interesting switch is "--time", which will generate at the end
of the test suite execution, a table with all executed tests and
respective start, end, user, system and real times. Note that the
switches may be used with make
check by including them in the TESTFLAGS environment variable.
Install Mercurial by running the
following command (as root):
make PREFIX=/usr install-bin
If you built the documentation, install it by running the following
command (as root):
make PREFIX=/usr install-doc
After installation, two very quick and simple tests should run correctly. The first one needs some configuration:
cat >> ~/.hgrc << "EOF"
[ui]
username = <user_name> <user@mail>
EOF
where you must replace <user_name> and <your@mail> (mail is optional and can be omitted). With the user identity defined, run hg debuginstall and several lines will be displayed, the last one reading "no problems detected". Another quick and simple test is just hg, which should output basic commands that can be used with hg.
sed -i '/runrst/s/N)/N)3/' doc/Makefile: forces the use of Python 3 for commands using docutils, allowing to use the docutils Python 3 module.
2to3-3.7 -w doc/hgmanpage.py: Since Python 3 is used with docutils, one file needs to be converted in order to be compatible.
/etc/mercurial/hgrc and
~/.hgrc
The great majority of extensions are disabled by default. Run hg help extensions if you need to enable any, e.g. when investigating test failures. You will obtain the lists of enabled and disabled extensions, and more information, such as how to enable or disable them using configuration files.
If you have installed make-ca-1.4 and
want Mercurial to use them, as
the root user, issue:
install -v -d -m755 /etc/mercurial &&
cat > /etc/mercurial/hgrc << "EOF"
[web]
cacerts = /etc/pki/tls/certs/ca-bundle.crt
EOF
