For Mac OS, upon starting KA Lite, can not process to open the website

[JohnJCZhou]

Click on KA-Lite monitor and after it is loaded it will look like this:

After clicking on "Start KA Lite" the the system will get stuck in this status:

Even if I try to open it in browser by manually typing address: 127.0.0.1:8008, the page won't load.

Hi @JohnJCZhou - I assume that you have already configured your Preferences? What build of the .dmg did you use?

Can you open Terminal and type kalite status? If it's open already, please close it and re-open (to load the environment variables used by the kalite executable).

@JohnJCZhou & @cpauya I reproduced this issue, if I download any kalite videos that fails to download and I stop and start the kalite monitor. And If I don't download any kalite videos and I stop and start the kalite monitor this issue will not reproduce. I used build #165 osx installer from dungeon.

@JohnJCZhou and @amodia:

I think what happened was that you tried to download a video first, which failed throwing the DatabaseError: no such table: chronograph_job error as commented here - then tried to start/stop the server.

To verify the above

1. Make a clean install of the OSX installer using build 165.
2. Start the server.
3. Download a video, which will fail.
4. Go to the Terminal and run kalite start which will give this output:

cyril-lappy6:~ cyril$ kalite start
Running 'kalite start' as daemon (system service)

Stand by while the server loads its data...

/Applications/KA-Lite Monitor.app/Contents/Resources/ka-lite/kalite/settings/base.py:43: RemovedInKALite_v015_Warning: We will be deprecating the old way of statically importing custom settings, in favor of a more flexible way. The easiest way to update your installation is to rename your local_settings.py (keeping it in the same directory) and add an import statement in the very first line of the new file so it looks like this:

    from kalite.project.settings.base import *
    # Put custom settings here...
    FOO = BAR

and then call kalite start with an additional argument pointing to your new settings module:

    kalite start --settings=kalite.my_settings

In the future, it is recommended not to keep your own settings module in the kalite code base but to put the file somewhere else in your python path, for instance in the current directory when running 'kalite --settings=my_module'.

INFO:kalite:Running 2 due jobs... ("Secure Sync", "Download Videos")

The last line above tells us that ka-lite tried to run the pending jobs but stopped. I checked the ~/.kalite/server.log file but it has no content with 0 bytes.

To double-check

1. Make a clean install using build 165.
2. Use the site, but do not download a video.
3. Start and stop the server, either using the menu icon or the kalite executable on the Terminal.
4. Notice that this will work as intended.

So I think this issue will get fixed when we fix #3704 first.

@cpauya we didn't implement proper logging :) So the log is truncated everytime you restart. This is to ensure that filesizes don't run away until we've implemented a proper global logging mechanism. This won't happen in 0.14, so remember to grab the logs right away :)

A lot of churn has happened in the Mac installer since this was opened. Let's create another issue if this crops up again. @cpauya feel free to dissent.
