missingbits 0.0.8

missingbits:range

This recipe takes a string and will make a list out of it. For example, where as you could write:

[buildout]
parts = cluster

[cluster]
recipe = plone.recipe.cluster
start =
    ${buildout:bin-directory}/zope0 start
    ${buildout:bin-directory}/zope1 start
    ${buildout:bin-directory}/zope2 start
    ${buildout:bin-directory}/zope3 start
    ${buildout:bin-directory}/zope4 start
    ${buildout:bin-directory}/zope5 start
stop =
    ${buildout:bin-directory}/zope5 stop
    ${buildout:bin-directory}/zope4 stop
    ${buildout:bin-directory}/zope3 stop
    ${buildout:bin-directory}/zope2 stop
    ${buildout:bin-directory}/zope1 stop
    ${buildout:bin-directory}/zope0 stop

You can write:

[buildout]
parts = cluster

[zopes]
recipe = missingbits:range
stop = 6
cluster-start = ${{buildout:bin-directory}}/zope{0} start
cluster-stop = ${{buildout:bin-directory}}/zope{0} stop

[cluster]
recipe = plone.recipe.cluster
start = ${zopes:cluster-start.forward}
stop = ${zopes:cluster-stop.reverse}

This is most useful when the number of zopes might vary for different builds of the same site.

missingbits:clone

I don’t like copying and pasting things in buildout, i tend to make mistakes. So I clone instead.

A site with 4 zopes might look something like this:

[buildout]
parts =
    zope0
    zope1
    zope2
    zope3

[zope0]
<= instance
http-address = ${hosts:zope}:${ports:zope0}
event-log = /var/log/zope/www.foo.bar.zope0.event.log
z2-log = /var/log/zope/www.foo.bar.zope0.Z2.log

[zope1]
<= instance
http-address = ${hosts:zope}:${ports:zope1}
event-log = /var/log/zope/www.foo.bar.zope1.event.log
z2-log = /var/log/zope/www.foo.bar.zope1.Z2.log

[zope2]
<= instance
http-address = ${hosts:zope}:${ports:zope2}
event-log = /var/log/zope/www.foo.bar.zope2.event.log
z2-log = /var/log/zope/www.foo.bar.zope2.Z2.log

[zope3]
<= instance
http-address = ${hosts:zope}:${ports:zope3}
event-log = /var/log/zope/www.foo.bar.zope3.event.log
z2-log = /var/log/zope/www.foo.bar.zope3.Z2.log

When the number of zopes can change, we really need to make this more manageable. We could do this instead:

[buildout]
parts = zope-factory

[zope{0}]
<= instance
http-address = ${{hosts:zope}}:${{ports:zope{0}}}
event-log = /var/log/zope/www.foo.bar.zope{0}.event.log
z2-log = /var/log/zope/www.foo.bar.zope{0}.Z2.log

[zope-factory]
recipe = missingbits:clone
template = zope{0}
count = 4

missingbits:echo

While testing these recipes it was handy to have a no-op recipe that just printed some text. This is that recipe.

You can print text from your buildout like so:

[buildout]
parts = echo

[echo]
recipe = missingbits:echo
echo = Any text you want here

0.0.8 (2011-09-21)

• Don’t reset self.name when resetting things - this works around ${:path} being invalid and the settings the stack uses shouldn’t be changing in flight - its just too weird!

0.0.7 (2011-09-15)

• Fix optional logic

0.0.6 (2011-09-15)

• Prior to the injection of any stack configuration, buildout._data is cleared (with the exception of the buildout and versions parts), causing any already- resolved parts to be re-resolved once the stack has been applied, and the original configuration re-applied.

0.0.5 (2011-09-09)

• Optional config loading support

0.0.4 (2011-09-02)

• All stacks automatically get a ‘path’ variable that points to their assets

• Fix sibpath for namespaced modules

0.0.3 (2011-09-02)

• Add ‘Stack’: a utility for packaging buildout as an egg.

0.0.2 (2011-08-08)

• Fix commit missing from merge

• Fix python2.4 support

0.0.1 (2011-08-05)

• Add overlay recipe

0.0.0 (a long long time ago..)

• Initial release
