Hello community,
I am having a problem when recording a soundfile using pure data in my iOS application.
Just like David’s message here: https://www.mail-archive.com/pd-list@lists.iem.at/msg08232.html I am having same behaviour with endless recursion:
writesf waiting for disk write.. (head 524032, tail 0, room 256, want 256) ... done waiting.
Pure Data is integrated in iOS app using cocoapods.
Maybe someone has some ideas? Maybe someone had this issue?
Many thanks, Sincerely,
Artem

infinite recursion? (i think you mean something else)
writesf waiting for disk write.. (head 524032, tail 0, room 256, want 256) ... done waiting.
it seems like the write thread fails to put bytes into the disk (and thus empty the data queue).
is the file created? do you get an "error" (disguised as an ordinary printout) when trying to open the file for writing?
does it help if you raise the buffer size (via the 2nd argument to [writesf~] - it's undocumented, but see [readsf~])
what happens if you close the file before the error appears? (e.g. does it get written?)

Dear Iohannes, Dear all,
Infinite recursion it is, it gets stuck in while block. The file is not created, I don’t receive any errors from Pd, I tried to stop recording just moments after record start and nothing happened, no error, but no file either.
It looks like Pd has no access or permission to write, yes?
Thanks, Artem

I’ve increased value to 3e+08, and I waited for this recursion for a minute, it did not occur, but the file was not created.
I have Objective C written application, where everything works as intended, and my Swift version is stuck on this one.
Any more ideas?

I got floods of this message when using -batch with something like
[open /path/that/does/not/exist.wav, start(--[writesf~ 2]
so maybe check that you have a valid writeable path...
In my case it was a typo on desktop Linux and easy to fix. I don't know where iOS lets you write files.
