README

This module fixes the case where an incomplete module_hook_info() call occurs.

This results in an incomplete list of module hook info being cached.

This seems to occur when using Drupal's "Clear all caches" button on the admin > configuration > development page, or the "Clear all caches" link in the Drupal Admin Menu module.

Symptoms of this issue occurring include Node tokens not working, and the presence of errors on pages which use Tokens such as the Pathauto configuration page, such as:

Notice: Undefined index: name in token_asort_tokens() (line 582 of ... token.module).

Default path pattern (applies to all content types with blank patterns below) is using the following invalid tokens: [node:title].

Because some data exists in the cache, Drupal assumes the data can be trusted when it cannot.

This issue is a particularly insidious one because it breaks almost all tokens, and as a result breaks a number of sites' layouts when they use tokens to set a path off which block placements hang - e.g. /news/*.

This module invalidates caches when they don't contain a mention of the Node module's token_info hook, since this should always be present if the node module is enabled.
