Feedback on experimental Mac Launcher for Python

[Brian Quinlan]

Hi,

Along with the usual components of the App Engine 1.6.5 release, we
also released an experimental version of the Mac OS X Launcher that
includes a siloed version of Python 2.7 (see
https://developers.google.com/appengine/downloads). Our reason for
providing this was to reduce the number of dependencies that Mac users
needed to download before they have a usable SDK.

This experimental launcher was downloaded >500 times but we haven't
received any feedback about it. Could anyone who downloaded and try it
please respond to this thread saying whether they had any problems or
not?

The more feedback we get, the better our release will be and your help
is really appreciated!

Cheers,
Brian

Hey Brian,

I did try the Mac OS version a couple times. The idea is nice. Not only because of "to reduce the number of deps". I think it's good to have dev appserver running in a "clean", separate environment, closer to how it works in production (e.g. I sometimes mess up my python 2.7 and site packages, making them do weird stuff, experimenting).

The reason I'm not using it daily (both with and w/o bundled python) is that I'd have it frozen (the Launcher app) so I had to "forse quit" it from Activity Monitor. And it happens too often so, at the end of the day I find myself using SDK *.py scripts directly from the Terminal (which I don't mind actually).

Unfortunately, I can't really provide some deterministic steps to reproduce "freezing" right now. But, I noticed it almost always happend when I click "stop" (to stop the dev appserver).

Thanks very much for the feedback!

Did this problem occur with the regular launcher or just the experimental one?

It occurs on both, the regular and experimental launchers. In fact, I don't believe it is something related to the differences between the two.

Actually, I've just launched it again with a minimal app, a single page rendered by Jinja2 on webapp2. 

It got frozen when I tried to stop the app server during an ongoing request handling. In fact, in the attached screenshot you'll see "KeyboardInterrupt" standard exception that normally happens if you CTRL-C the process in a terminal during a request handling, only that Launcher now got stuck and not even responding to "quit" so I've just had to force it.

I even checked out the (regular) launcher source code once to see if I could find out what's going on but I didn't really have time to get my hands on it.

Hope that helps!

PS I'm running Lion, but it happend to me before on Snow Leo too.

Brian, if it helps: 

create a new app and put "time.sleep(5)" as the first line of a "def get(self)" in a request handler. Now, run the app, click on Browse and, while browser's waiting those 5 sec, switch back to the Launcher and click "Stop". You should be able to get that freezing behavior. Well, unless there's something weird with my local setup. In the latter case I'd love to be able to figure out what it is as I really like the launcher and its simplicity.
