ro.bdb.cmmi 1.0.5

We have an archive with a demo foo tar ball:

>>> ls(distros)
-  foo.tgz

Let’s update a sample buildout to installs it:

>>> write('buildout.cfg',
... """
... [buildout]
... parts = foo
...
... [foo]
... recipe = ro.bdb.cmmi
... url = file://%s/foo.tgz
... """ % distros)

We used the url option to specify the location of the archive.

If we run the buildout, the configure script in the archive is run. It creates a make file which is also run:

>>> print system('bin/buildout'),
Installing foo.
foo: Downloading .../distros/foo.tgz
foo: Unpacking and configuring
configuring foo --prefix=/sample-buildout/parts/foo
echo building foo
building foo
echo installing foo
installing foo

The recipe also creates the parts directory:

>>> ls(sample_buildout, 'parts')
d  foo

If we run the buildout again, the update method will be called, which does nothing:

>>> print system('bin/buildout'),
Updating foo.

You can supply extra configure options:

>>> write('buildout.cfg',
... """
... [buildout]
... parts = foo
...
... [foo]
... recipe = ro.bdb.cmmi
... url = file://%s/foo.tgz
... extra_options = -a -b c
... """ % distros)

>>> print system('bin/buildout'),
Uninstalling foo.
Installing foo.
foo: Downloading .../distros/foo.tgz
foo: Unpacking and configuring
configuring foo --prefix=/sample-buildout/parts/foo -a -b c
echo building foo
building foo
echo installing foo
installing foo

The recipe sets the location option, which can be read by other recipes, to the location where the part is installed:

>>> cat('.installed.cfg')
... # doctest: +ELLIPSIS
[buildout]
installed_develop_eggs =
parts = foo
<BLANKLINE>
[foo]
__buildout_installed__ = /sample-buildout/parts/foo
...
extra_options = -a -b c
location = /sample-buildout/parts/foo
...

Sometimes it’s necessary to patch the sources before building a package. You can specify the name of the patch to apply and (optional) patch options:

First of all let’s write a patchfile:

>>> import sys
>>> mkdir('patches')
>>> write('patches/config.patch',
... """--- configure
... +++ /dev/null
... @@ -1,13 +1,13 @@
...  #!%s
...  import sys
... -print "configuring foo", ' '.join(sys.argv[1:])
... +print "configuring foo patched", ' '.join(sys.argv[1:])
...
...  Makefile_template = '''
...  all:
... -\techo building foo
... +\techo building foo patched
...
...  install:
... -\techo installing foo
... +\techo installing foo patched
...  '''
...
...  open('Makefile', 'w').write(Makefile_template)
...
... """ % sys.executable)

Now let’s create a buildout.cfg file. Note: If no patch option is beeing passed, -p0 is appended by default.

>>> write('buildout.cfg',
... """
... [buildout]
... parts = foo
...
... [foo]
... recipe = ro.bdb.cmmi
... url = file://%s/foo.tgz
... patch = ${buildout:directory}/patches/config.patch
... patch_options = -p0
... """ % distros)

>>> print system('bin/buildout'),
Uninstalling foo.
Installing foo.
foo: Downloading .../distros/foo.tgz
foo: Unpacking and configuring
patching file configure
configuring foo patched --prefix=/sample_buildout/parts/foo
echo building foo patched
building foo patched
echo installing foo patched
installing foo patched
