I'm not sure, if this is a bug or a peculiarity with opcache, but it's
definitely not a user question thus I am poating it in internals.

I came across a weird situation today that left me dumbfounded.

I have the following symbolic link:

index.php -> ../v1/idx.php

The link index.php is in the directory /data/pr/test/, yet the file
/data/pr/test/index.php was not in the list of cached files even though I=

certainly accessed the file and there's no blacklist and other files in t=
hat
directory were in the list. This was the first strange thing, but I thoug=
ht,
hey, maybe only the real file (/data/pr/v1/idx.php) is cached.

But here's the kicker:

After I changed the sym link to point to another file
index.php -> ../v2/index2.php
I had to reset the opcache that the correct page was served.

My revalidate_freq is set to 60 seconds. I also tested different browsers=
,
deleted the cache in the browser, waited for more than 60 seconds, nothin=
g
helped. Only resetting the cache solved the issue (I actually restarted f=
pm).

Please let me know, if I should open a bug or if opcache just doesn't wor=
k
with symbolic links.

Cheers,
  K. C.
