Hello,
I'd like to propose a version of opcache_is_script_cached(...) that
supports checking the file cache, rather than just SHM.
This would be useful when paired with opcache.file_cache_read_only,
as it would allow us to more easily check the cache is being used at
runtime.
It'll also allow us to more easily write automated tests against the
file based opcache, which I'd like to do retroactively for my
opcache.file_cache_read_only PR.
An example PR for this change is here:
https://github.com/php/php-src/pull/16979
I'd initially considered changing the function definition to
opcache_is_script_cached(string $filename, bool $file_cache = false), adding a new parameter, bool $file_cache = false, but
defaulting to false so the default / existing behaviour remains the
same: when the second parameter is true, it'll check JUST the file
cache, not SHM.
@Ilija Tovilo has suggested that it might be less confusing to make it
its own function, which I'm happy to do.
Does anyone want to weigh in on what you think of this functionality,
and if/how you'd like to see it implemented?
Regards,
Samuel Melrose
