timeout support

See original GitHub issue

It would be nice, if the OCR functions would support timeouts (on py2k f.e via https://github.com/google/python-subprocess32). Forgive me if there’s a tesseract binary flag for this as I can’t find it 😦 Cheers.

I’ve been battling with this issue for a while now. As I am reading lot of PDFs and tesseract processes become zombies as they couldn’t read the PDF for some reason (I’m assuming corrupted PDFs). Overtime this compounds and hogs up all the processes without doing anything.

I believe this can be fixed by using communicate(timeout=xx) at line 189.

I haven’t tested it. Please correct me if I’m wrong.

Just ran into this same problem. Can confirm that adding a timeout=XX works fine.

@starenka you are absolutely right, but it doesn’t seem like a very good idea to add support for the 2.7 version via third party lib that will become legacy pretty soon.

I understand the need for timeout functionality (which also involves manually killing the hanging tesseract process, since the python timeout functionality just unblocks the code execution), but maybe we should add a more elegant solution.
