running viewrendered hard crashes leo

[lewis]

Please be careful running the latest commit aa6d703a83c1 as you can hard crash leo with alt-x vr

Here is the console logfile after the rapid close:
** isPython3: True
Leo 5.4-devel, build 20160412153848, Tue Apr 12 15:38:48 CDT 2016
Git repo info: branch = master, commit = aa6d703a83c1
Python 3.5.2, PyQt version 5.6.0
Windows 7 AMD64 (build 6.1.7601) SP1
Could not find QtWebEngineProcess.exe

I know this is related to the QtWebEngine issues but the crash has only occurred with the latest commit.

Lewis

Running any Help command also crashes leo.

Hi Lewis,

Would you mind checking that this definitely doesn't happen in 9d28e6c?
I made aa6d703 but am not seeing the crash. It did change vr3, but not
in ways that should hard crash.

Thanks, Terry

Hi Terry,

I need your help with downloading commit 9d28e6c. I found it at https://github.com/leo-editor/leo-editor/commits/master but how do I pull it using git?
I normally just run 'git pull' for the most recent.

Thanks
Lewis

[lewis]

I'll try downloading the zip file of 9d28e6c.

Lewis

[lewis]

Downloaded the zip file of 9d28e6c zip file, unzipped and copied it to my usual leo folder. But when I run Leo the log says
Leo Log Window

Leo 5.4-devel, build 20160412153848, Tue Apr 12 15:38:48 CDT 2016

Not running from a git repo

I expected it to be 9d28e6c so I don't think that is helpful to you.

Lewis

From your git repo directory, you can do:

git checkout 9d28e6c

That will revert your files to the state at commit 9d28e6c.  To switch back to master (current), do:

git checkout master

Jacob's approach works, but the .zip file you downloaded would work
too, it just doesn't know its commit ID when you download it that way.

Cheers -Terry

[lewis]

Many thanks to Jacob for the tip on git checkout.

The crash also occurs with commits 9d28e6c (confirmed with zip and git repo) and 582fe79. 

I had to go back to 250ad23 to eliminate the crash behaviour.

Lewis

I wonder if this would fix it:

https://riverbankcomputing.com/pipermail/pyqt/2016-April/037400.html

"""
The QtWebEngineProcess.exe can be
found in C:\Qt\Qt5.6.0\5.6\msvc2013_64\bin

...

You can try setting the QTWEBENGINEPROCESS_PATH environment variable
to the full pathname of the .exe.

​It looks like the culprit is 582fe79: Attempt to support pyqt 5.6 so that viewrendered3 & bigdash plugins will load.

I have been waiting for a PR based on this post from Reinhard, but that hasn't happened, so I'll just up the suggested code myself.

Rev 329acf adds Reinhard's code and fixes pyflakes warnings about
undefined references to 'pos'. Let me know if it works any better.

pyflakes also issues these complaints:

viewrendered3.py:1663: local variable 'pc' is assigned to but never used
viewrendered3.py:1664: local variable 'mf' is assigned to but never used
viewrendered3.py:1946: local variable 'pc' is assigned to but never used
viewrendered3.py:1947: local variable 'mf' is assigned to but never used

I'm not sure that these "unnecessary" statements can be removed--there
may be side effects. Probably not, but let's deal with these warnings
later, after everything else works.

Edward

[lewis]

Running 329acf these log messages don't appear at startup:

 loadOnePlugin: can not load enabled plugin: leo.plugins.viewrendered3

 loadOnePlugin: can not load enabled plugin: leo.plugins.bigdash
So the plugins appear to be loading.

However leo still crashes if I run alt-x vr

PyQt5 v5.7 has been released and instructions for installation are at http://pyqt.sourceforge.net/Docs/PyQt5/installation.html
It seems .exe file are no longer provided. PyQt5 now uses wheel files which apparently are a new standard of python distribution. The good news is the installation worked :)

From a console window:

C:\Python35
pip3 install pyqt5
[snip]
Installing collected packages: sip, pyqt5
Successfully installed pyqt5-5.7 sip-4.18.1

C:\Python35>

And here is my leo log file:

Next, I'll test out the viewrendered plugin.

With pyQt5 v5.7 installed, Leo stays running after alt-x vr
