TYPO3 Core

The new 9284.diff is from Ingo Renner in the core mailinglist

another try:

i removed the hook and the sql-query and reduced this patch that it only reacts on

$GLOBALS['TSFE']->cacheExpires

i uploaded another patch

this time with an additional function to set cacheExpires Timestamp

Attaching a corrected patch, as submitted in the core list

I have tested this patch with a quickly put together extension, which I am attaching here. The extension is called "xnews". It's a FE plugin that just gets the 10 latest records from the tt_news table (so you need tt_news installed too). There's no configuration at all. Just insert an instance of xnews on some page and display the page. You should a list of 10 news items plus an indication of when the next update should take place, i.e. when the cache will expire.

To test properly you obviously need to have at least 1 tt_news with a starttime in the future.

You can check if that matches the information stored in the cache_pages table.

The xnews extension actually relies on an (as yet) unpublished extension called "overlays" (and this is even a modified version just for testing this patch). So you need to install "overlays" too. "overlays" is used to simplify querying the DB in particular in a multilingual setup. In this case I added a method for simply getting all records in the future and calculating a precise expiry time for the cache.

Please, see also #20473. It provides an automatic solution to this problem.

hi dmitry,

in my eyes
#20473
is an better approach.

The functionality described in this issue-description is what #20473 (already commited now) offers. So I'd say we should close this one.
