Thanks Tim. I'll review this shortly. + pipe = open(options.pipe, 'w') That creates a normal file. Use os.mkfifo() to create a named pipe on disk and then stream the data through that. This will avoid what is currently a delayed copy operation. (In reply to comment #2) > + pipe = open(options.pipe, 'w') > > That creates a normal file.

The pipe I was using to test was originally created with os.mkfifo(). I will extend the script to do check for if a file exists, if so that it is a fifo and if not create the fifo with the os.mkfifo method. Created attachment 36550 [details] [review] Time delta for logs and replay script 02 Have attached an improved patch that checks specified fifo is valid. Note this patch also extends the simple-gps-python.py to allow the baud rate to be set. Since my testing is with a serial over USB based GPS setting the baud rate is necessary. |
