Re: prebuild sage v5.4.1, linux 32-bit: twistd get wrong pidfile name when starting notebook(dir=..)

[Stan Schymanski]

This is still a problem in Sage 5.5, and on linux 64-bit. Have you found a workaround?

Cheers
Stan

I'm trying to update to sage 5.4.1. When I start a notebook without a directory parameter, everything goes fine. But if I want to start a notebook with:

sage: notebook(directory="/home/sage/s/",interface='')

I get an error message.

There is indeed no file /./../s/sagenb.pid, because sage creates a directory /./../s.sagenb/ .

I just found the related bug report and added a workaround: https://github.com/sagemath/sagenb/issues/116
