[Freeswitch-users] Question about httapi app cached audio files

[Lin, Xiaoping]

Hi! Mike,

Thank you very much for your reply! I did a little research and find your name in the contributor list of contributors for switch_ivr_play_say.c and hope you do not mind I go further, hope to get your opinion and suggestions.

Our product is running under 60k/hour call volume. Each call may have 3 to 4 files and plus the meta files. Cron job may end up to impact the performance badly.  Our production owner cannot accept that solution.

From the log file I noticed:

(1). Mod_httpapi.c line 2631 created the cache file
(2). switch_ivr_play_say.c:1910 plays the file, even from the message, I cannot tell it plays from the original or from the cached.

I am wondering if the purpose of saving the cache is for playing audio in full from the local, because it creates file with different name each time. If  switch_ivr_play_say.c:1910 knows that it has done with playing, why not just delete the files (wav and meta) after playing? Can we have a quick fix? Any other suggestions?

Many Thanks!

either they are not re using the cache due to cache expiry or other reason not to cache.  A corn job should be able to clean up older files in this for, or could even look at the metadata and kill stale cache files.  I don't think we have any code or script to do this currently.  A script or patch for a command to do that would be a nice addition

Hello,

We are developing an app using httapi (FreeSwitch 1.6). Our installation and support engineer reported cached audio files have been dumped under

/var/lib/freeswitch/storage/http_file_cache

They are not cleaned and take all the disk space after running for a period time. The files list look like:

-rw------- 1 freeswitch daemon   124 Aug 12 16:28 ef98679d646e00a3a6f5b9265a6b8a21.meta

-rw------- 1 freeswitch daemon 91192 Aug 10 14:08 feb0d10f984b4ea85e9f6645f561bbf4.wav

Even the files are the same, it was saved with different file names and never got cleaned.

Anyone has the same problem and what is the correct way to deal with this?

Many thanks!
