Mercurial-2.9

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-7.5 platform.

Mercurial Dependencies

Required

Python-2.7.6

Optional

Docutils (required to build the documentation), git-1.9.0, GnuPG-2.0.22 (gpg2 with Python bindings), Subversion-1.8.5 (with Python bindings), Bazaar-2.5.1, CVS-1.11.23, pyflakes, pygments, and pyOpenSSL

Installation of Mercurial

Build Mercurial by issuing the following command: 

make build

To build the documentation (requires Docutils), issue: 

make doc

To test the results, issue: make check. During the tests, the build directory size increases above the “Estimated disk space required”, even when considering the additional values, due to temporary test files.

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"
[ui]
username = <user_name> <your@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.

Configuring Mercurial

Config Files

/etc/mercurial/hgrc

If you have installed the Certificate Authority Certificates and you want Mercurial to use them, as the root user: 

install -v -d -m755 /etc/mercurial &&
cat > /etc/mercurial/hgrc << "EOF"
[web]
cacerts = /etc/ssl/ca-bundle.crt
EOF
