Products.TemporaryFolder 8.0

Zope temporary folder support.

Overview

Zope temporary storage / folder support.

Please note

Before release 5.2 of the tempstorage package sessioning configurations using this temporary folder implementation were discouraged because the temporary storage backend could lose data. This is no longer the case.

Don’t forget to add or uncomment the temporary storage database definition as shown below in your Zope configuration if you want to instantiate a temporary folder. After a Zope restart, visit the Zope Management Interface and select ZODB Mount Point from the list of addable items to activate the temporary folder mount point:

<zodb_db temporary>
    <temporarystorage>
      name Temporary database (for sessions)
    </temporarystorage>
    mount-point /temp_folder
    container-class Products.TemporaryFolder.TemporaryContainer
</zodb_db>

When upgrading from version 5.3 to 6.0 and removing the ZODB Mount Point configuration shown above from your Zope configuration you need to manually delete the /temp_folder object in the ZMI before restarting your Zope instance with version 6.0. If you see tracebacks ZConfig.ConfigurationError: No database configured for mount point at /temp_folder after the upgrade, please reinstate the zodb_db temporary Zope configuration as shown above, restart Zope and manually delete /temp_folder. Then remove the zodb_db temporary configuration and restart Zope.
