Say I have a cache warmer that fails due to an exception. The container is already written, so on the next request the cache warmer is not triggered again.

I wonder if we need to somehow ensure that in such cases the entire cache is considered tainted so that it gets regenerated on the next request?

Right now I think Bundle developers assume that their compiler passes have executed without error and therefore do not handle the case when they may have failed due to an exception.

I noticed this issue while working on doctrine/DoctrinePHPCRBundle#159

hmm, is it a failing compiler pass or a failing cache warmer ? These are not the same thing

A cache warmer is not about building the container (there is no container cache warmer). Each cache warmer is about building its own part of the cache (the router cache warmer dumps the cached router for instance). The fact that the cache is regenerated on the next request or no depends of how this cached content is used.
But there is no reason to trigger a regeneration of the whole cache on next request IMO.

yeah .. I can understand the current behavior .. I am just not sure if cache warmer authors are really aware of this. maybe in the end however this is thereforemore a documentation thing, where we need to make it very clear to Bundle authors that essentially they have no guranteed that a cache warmer has run successfully before the rest of its code is executed.

Closing it because this can be solved via documentation as mentioned by @lsmith77. See symfony/symfony-docs#6215.
