Device name limited to 39 characters

[Ryan Finnie]

Recent udev in Ubuntu includes nifty permanent mappings for serial devices; for example, my 1wire master shows up as /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A800bZvc-if00-port0. However, when I try to use this with digitemp:

$ sudo digitemp_DS9097U -w -s /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A800bZvc-if00-port0

Error, serial port '/dev/serial/by-id/usb-FTDI_FT232R_USB_U' does not exists!

Attached is a patch bumping this limit from 39 (40 minus null) chars to 1023 (1024), fixing the problem:

$ sudo digitemp_DS9097U -w -s /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A800bZvc-if00-port0

I will be submitting this upstream as well.

I don't see the upstream forwarding on http://groups.google.com/group/digitemp?pli=1; would you mind putting the link here for tracking this? Thanks!

I did not get around to posting to upstream-upstream yet, after noticing there was an updated release from 2008 that was not packaged in Debian. The net result of that is I will be adopting Debian-upstream (see http://bugs.debian.org/668334) and will shortly be reaching out to upstream-upstream in that capacity. :)
