Introduction to Mercurial

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-7.8 platform.

Mercurial Dependencies

User Notes:

Installation of Mercurial

Build Mercurial by issuing the following command:

make build

To build the documentation (requires Docutils), issue:

make doc

Running the test suite is optional. If there are failures, e.g. test-parse-date.t, those tests can be disabled. To test the results in the subdiretory tests/tmp, skipping failing tests, issue:

cat > tests/blacklists/failed-tests << "EOF"
# Test Failures
rm -rf tests/tmp &&
TESTFLAGS="-j<N> --tmpdir tmp --blacklist blacklists/failed-tests" \
make check

where <N> is an integer between one and the number of processor threads, inclusive. In order to investigate a particular apparently failing test, e.g “test-parse-date.t”, issue the following commands (notice that omitting --debug sometimes modifies the result):

pushd tests &&
rm -rf tmp  &&
./ --debug --tmpdir tmp test-parse-date.t &&

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 installed, two very quick and simple tests should run correctly. First one needs some configuration:

cat >> ~/.hgrc << "EOF"
username = <user_name> <your@mail>

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.

Configuring Mercurial

Config Files

cat > /etc/mercurial/hgrc << "EOF"
cacerts = /etc/ssl/ca-bundle.crt


Installed Programs: hg
