macOS wait for wrong message, significantly delaying notebook launch

Description needs to be updated.

150:                         " grep --line-buffered -i 'ipython notebook is running at' |"
151:                         " grep --line-buffered -o http://.*",

This code waits for the message ipython notebook is running at and expects the token to be on the same line.

However, the log file (~/Library/Logs/sage.log) no longer conforms to this. The message has changed and the token is on the next line. Example from version 8.9:

[I 20:31:00.976 NotebookApp] The Jupyter Notebook is running at:
[I 20:31:00.976 NotebookApp] http://localhost:8888/?token=cc2c728ae01f2c3851df1a413a9661f17ca3301b15a9f6e8

The consequence of this mismatch is a very long wait when launching Sage notebook using the bundled app.

I believe we can use

grep -i --context 1 'jupyter notebook is running at' | grep -o http://.*

to obtain the token instead.

Thanks! I do not have a way to build and test this, but I do believe this fix would work based on a simulation (cat ~/Library/Logs/sage.log | grep -i --context 1 'Notebook is running at' | grep -o http://.* correctly extracts the URL on my mac.)

I guess you could dare to set the ticket to "positive review". It cannot become worse than before.

comment:4 Changed 3 years ago by jhpalmieri

I support this.

So please gh-maverickwoo, fill the "Reviewers" field in the ticket with your full real name and set the status to 'positive review', if you want.
