I am working on a
Symfony 3.4 based projects which uses a WSSE authentication as described in the Symfony docs.
Each nonce is stored as separate file in the cache dir
myProject/var/cache/prod/security/nonces. Probelm is, that this dir becomes very, very large in size. The project has been up and running and the nonces already use almost 20GB in disk space!
$ cd myProject/var/cache/prod/security/ $ du -sch * 19G nonces 19G total
This seems pretty much to me… I tried to figure out how many nonces are stored and used the following command to count the files:
$ cd myProject/var/cache/prod/security/nonces $ find -maxdepth 1 -type f | wc -l 4697417
Even for 4.7 million files 19GB seems pretty much. Each file would need to have a size of roughly about 4KB. However, as far as I can tell each file has only 10B…
$ cd myProject/var/cache/prod/security/nonces $ ls -lh -rw-r----- 1 user nobody 10 Jul 25 16:46 'MWFiYWM5YjAiOTRyOWRmZA==' -rw-r----- 1 user nobody 10 Jul 1 19:41 'MWFiYWNiYTflNTdhLGYwYQ==' -rw-r----- 1 user nobody 10 Sep 29 11:05 'MWFiYWNkNzEjZfFlCjM0OQ==' ...
I know that there is a difference between file size and consumed diskspace. However,
du also shows 10B of disk space:
$ du -sb --apparent-size MWFiYWNkNzEjZfFlCjM0OQ== 10
So, how can the files use 19G of disk space while each files only uses 10B? Am I missing something? Or did I not use the commands correctly?
Isn’t there a better to store the nonces?
Of course I could delete the cache every now and then. However, this would make the nonces pretty much useless, wouldn’t it?
