Hello List,
as it seems to be patch submission time, I'm pushing two patches to the
list, I had lying around for some time now.
The first patch allows mock to parse a generic side-wide config file,
where general configuration-items can be stored and later overridden by
specific chroot-definitions.
The second patch, is a bit different:
While pushing the Fedora Core SRPMS through the mock buildsystem we
noticed many SRPMS which do not correctly define their buildrequirements.
Until the fedora core developer responsible for the package has updated
the spec in cvs and pushed an updated srpm into rawhide, there is no way
to make the package in question build in mock without having to change the
.spec.
Thus, in order to allow even these broken packages being built, we needed
a way to work around these broken dependencies to see if anything else was
missing.
This is done by the second patch, which adds a more_buildreqs config
option. If set the given dependencies are installed _in addition_ to the
ones from the .spec file.
While the second patch should not be used during normal use and is
definetly not for the fedora-extras buildservers, it still is of interest
to other parties, using mock.
regards,
andreas
Provide generic config defaults.
* Support a generic /etc/mock/defaults.cfg config file. The values
defined in this file are overwritten by any definitions in the
specific /etc/mock/CHROOT.cfg files.
This part just introduces mock-0.4/etc/defaults.cfg and
adds the last chunk in the patch to mock-0.4/mock.py.
This patch was written in 2006 for bawue.net by Hans Ulrich Niedermann in
2006 after an idea by Andreas Thienemann. Testing and final clean-up was
one by Andreas Thienemann.

Provide extra build requirements for packages.
* Introduce a new config variable 'more_buildreqs' which allows
defining additional build dependencies for specific packages.
This is useful for buggy SRPMs or SRPMs which compile some
parts conditionally, depending on the software installed.
This mechanism should not be used in normal operation.
The extra build requirements can be configured like in the following
example, in which we use the example of a fictitional SRPM file
called 'ser-0.9.6-3'.
# matches only the 'ser-0.9.6-3' package
config_opts['more_buildreqs']['ser-0.9.6-3'] = [ 'smtp-devel >=
1.2',
'mysql-devel >= 5.0', 'png-devel < 0.1', 'tcsh' ]
# matches all 'ser-0.9.6-*' packages
config_opts['more_buildreqs']['ser-0.9.6'] = [ 'smtp-devel >=
1.2',
'mysql-devel >= 5.0', 'png-devel < 0.1', 'tcsh' ]
# matches all 'ser-*-*' packages
config_opts['more_buildreqs']['ser'] = [ 'smtp-devel >=
1.2',
'mysql-devel >= 5.0', 'png-devel < 0.1', 'tcsh' ]
The most specific match is used, i.e. if requirements for
'ser-0.9.6-3' are defined, the definitions for 'ser-0.9.6' and
'ser'
are ignored. Each time, /etc/mock/CHROOT.cfg is checked first, and
only if there is no dependency definition here, the definition from
/etc/mock/defaults.cfg is checked.
