stdWrap.cache doesn't use cached entries
Added by Julian Hofmann over 6 years ago.
Updated over 6 years ago.
Description
Tried to use stdWrap.cache on different instances (TYPO3 7.6.23 and 8.7.8) according to https://docs.typo3.org/typo3cms/TyposcriptReference/7.6/Functions/Cache/ But the content is rendered for each page instead of sharing it with other pages.
Also the exact example doesn't work:
page = PAGE
page.5 = TEXT
page.5 {
stdWrap.cache.key = mycurrenttimestamp
stdWrap.cache.tags = tag_a,tag_b,tag_c
stdWrap.cache.lifetime = 3600
stdWrap.data = date : U
stdWrap.strftime = %H:%M:%S
}
- Status changed from New to Needs Feedback
Can you check if the following works for you:
page.10 = TEXT
page.10 {
cache.key = mycurrenttimestamp
cache.tags = tag_a,tag_b,tag_c
cache.lifetime = 3600
data = date : U
strftime = %H:%M:%S
}
I think there is a documentation change missing since https://review.typo3.org/#/c/35915/15 was merged.
Thank you, your snippet works and I could solve my usecase.
But I think, it is not only a missing documentation change.
"cache" is currently documentated under "Function" (with wrong example), but also as Property of stdWrap (with link to cache function). So, the stdWrap.cache example should work, too. Or is there no cache-property in stdWrap anymore? But stdWrap.cache is writing to the cache (or at least stores the cache-identifiers) but doesn't get data from the cache.
It does get data from the cache but due to the execution order of the stdWrap properties the data gotten from the cache gets overwritten by the subsequent stdWrap calls. If I understand the history correctly before the change the "cache get" stopped the execution of the subsequent calls while now the result from "cache get" gets set as value and is then used in further potential processing. I'm not sure which way is more / less correct or what the intended behaviour was. I'll try to figure it out.

So this makes it a documentation-issue then. Thanks - updated.
No, it is not just a documentation thing.
The breaking.rst says "``stdWrap.cache`` continues to exist and can be used as before." - this is not true. It is not working like before.
The break is discribed for cases where "you've previously used the ``cache.`` property in your custom cObject", not for normal (non-custom) cObjects.
