Operating system: n/a
PHP version: 7.2.2
Package: opcache
Bug Type: Feature/Change Request
Bug description:opcache_invalidate requires file presence
Description:
------------
opcache_invalidate()/zend_accel_invalidate does:
realpath = accelerator_orig_zend_resolve_path(filename,
filename_len);
if (!realpath) {
return FAILURE;
}
accelerator_orig_zend_resolve_path ends up calling php_resolve_path that
again
does a tsrm_realpath() that ends up doing lstat() that in the end makes
php_resolve_path return NULL and zend_accel_invalidate return FAILURE.
This means it is not possible to invalidate a file that is removed from
the filesystem without flushing the entire opcache. This can be
problematic in general and for esoteric in particular.
I understand the fact that one might try to resolve symlinks to find
real cache key, but there should imho be a way to override this and
enable the invalidation.
Another related issue is that opcache_invalidate does not actually free
up memory, just marks the cached code as corrupted. How impossible would
it
be to implement a opcache_delete call that would do all this?
