Introduction

This package provides a mechanism to easily have clients set to work with readonly.

This is mostly useful for preventing ReadOnlyError from cropping up from write on read operations for a public read only site.

Warning

Also make sure to set your zeo client zope.conf read-only true setting:

<zodb_db main>
    <zeoclient>
    ...
    read-only true
    ...
    </zeoclient>
</zodb_db>

To make this work along with buildout, use the wildcard.recipe.insertinto recipe:

[readonly-insertinto]
recipe = wildcard.recipe.insertinto
client1 = ${client1:location}/etc/zope.conf insert-before "</zeoclient>" "\n\tread-only true\n"

Lastly, make sure to disable product installation in your client configuration, otherwise you'll get errors on startup:

[client1]
recipe = plone.recipe.zope2instance
...
enable-product-installation off
...
Usage
Abort all transactions

Aborts transaction on IPubBeforeCommit event.

Add this to the zcml-additional option for your client:

[client1]
recipe = plone.recipe.zope2instance
...
zcml-additional =
    <include package="wildcard.readonly" file="readonly.zcml" />
...
Doom all transactions

Dooms the transaction on the IPubAfterTraversal event.

Add this to the zcml-additional option for your client:

[client1]
recipe = plone.recipe.zope2instance
...
zcml-additional =
    <include package="wildcard.readonly" file="readonly-doom.zcml" />
...
Conditionally abort transactions

Useful when aborting all transactions prevents emails from getting sent out. For instance, if you're using PloneFormGen in your setup, dooming and aborting will prevent mail from getting sent.

Add this to the zcml-additional option for your client:

[client1]
recipe = plone.recipe.zope2instance
...
zcml-additional =
    <include package="wildcard.readonly" file="readonly-conditional.zcml" />
...
