Easily setup readonly zeo clients
Project description
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 read-only recipe config option. Also, make sure to disable product installation in your client configuration, otherwise you’ll get errors on startup. Make sure to use plone.app.zeoclient >= 4.2.12 as it includes the read-only config option:
[client1] recipe = plone.recipe.zope2instance ... read-only = true 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" />
...
Handling sending mail
Since mail is tied to transaction management, aborting all transactions will also prevent sending mail on the site.
Add this to the zcml-additional option for your client:
[client1]
recipe = plone.recipe.zope2instance
...
zcml-additional =
<include package="wildcard.readonly" file="mail.zcml" />
...
