==Description==
 +
Mock-urpm  is  a  simple  program  that will build source RPMs inside a chroot. It doesn't do anything terribly fancy other than populate a chroot with the contents
 +
specified by a configuration file, then build any input SRPM(s) in that chroot.
 +
 
 +
The content of a chroot is specified by the configuration specified with the -r option. The default configuration file is /etc/mock-urpm/default.cfg, which is usu‐
 +
ally a symlink to one of the installed configurations.
 +
 
 +
There  is  a site-wide configuration file, /etc/mock-urpm/site-defaults.cfg, which can be used to specify site-wide options. The shipped version of this file has no
 +
active options, but does have a list of all of the configuration options, examples of how to set them, and their default values.
 +
 
 +
To use mock-urpm, a user should become a member of the mock-urpm group by adding their username to the mock-urpm line in /etc/group. This can be done with the  fol‐
 +
lowing command:
 +
 
 +
sudo /usr/sbin/usermod -a -G mock-urpm $USER
 +
 
 +
This command is executed automatically after the packet installation.  Note that mock is not intended to be run
 +
directly as root.
 +
 
 +
 
 +
===SCM===
 +
Using SCM (GIT/CVS/SVN) is really easy. Edit config files (there are examples with comments in site-defaults.cfg). Write the correct 'method' option ('git',
 +
 
 +
mock-urpm --scm-enable --scm-option package=PKG_NAME --scm-option branch=BRANCH_NAME SCM
 +
 
 +
must have a .spec file. Sources can be placed in tarball, but  putting '.write_tar' file to the project root will make mock-urpm to create NAME-VERSION.tar.gz archive.

Mock is a program that builds packages inside a chroot, originally by Fedora Project. The chroot contents are defined by a set of config files.

This package can be found in Rosa repositories. The newest version - in my private repository x86_64 or i586.

To install, run "sudo urpmi mock-urpm"; this will set up proper users, so you can instantly fire 

sudo mock-urpm /path/to/src.rpm --enable tmpfs


See logs and results in /var/lib/mock-urpm/{rootname}/results.

Read more at "man mock-urpm". The tool originates from Fedora, see an article about mock there.


Description

Mock-urpm is a simple program that will build source RPMs inside a chroot. It doesn't do anything terribly fancy other than populate a chroot with the contents specified by a configuration file, then build any input SRPM(s) in that chroot.

The content of a chroot is specified by the configuration specified with the -r option. The default configuration file is /etc/mock-urpm/default.cfg, which is usu‐ ally a symlink to one of the installed configurations.

There is a site-wide configuration file, /etc/mock-urpm/site-defaults.cfg, which can be used to specify site-wide options. The shipped version of this file has no active options, but does have a list of all of the configuration options, examples of how to set them, and their default values.

To use mock-urpm, a user should become a member of the mock-urpm group by adding their username to the mock-urpm line in /etc/group. This can be done with the fol‐ lowing command: 

sudo /usr/sbin/usermod -a -G mock-urpm $USER

This command is executed automatically after the packet installation. Note that mock is not intended to be run directly as root.


SCM

Using SCM (GIT/CVS/SVN) is really easy. Edit config files (there are examples with comments in site-defaults.cfg). Write the correct 'method' option ('git', 

mock-urpm --scm-enable --scm-option package=PKG_NAME --scm-option branch=BRANCH_NAME SCM

must have a .spec file. Sources can be placed in tarball, but putting '.write_tar' file to the project root will make mock-urpm to create NAME-VERSION.tar.gz archive.

--cwd=DIR Change to the specified directory (relative to the chroot) before running command when using --chroot
-q, --quiet Be quiet.
-v, --verbose Output verbose progress information.
--trace Enables verbose tracing of function enter/exit with function arguments and return codes. Useful for debugging mock itself.

Examples

To rebuild test.src.rpm using the configuration for x86_64 named "my_configuration" 

mock-urpm -r my_configuration-x86_64 --rebuild /path/to/test.src.rpm

Note that the available configurations are found in the /etc/mock-urpm directory with the extension .cfg. To specify a configuration use the filename without the trailing .cfg extension.

To place the output RPMs and logs in a specified location. 

mock-urpm --resultdir=./my-results /path/to/your.src.rpm

To build a package from the default SCM repository configured in site-defaults.cfg or in user config use the following arguments. 

mock-urpm --scm-enable --scm-option package=pkg
