calculator doesn't calculate: parse error in math.js

[Jean-Baptiste Lallement]

current build number: 31
device name: frieza_arm64
channel: ubuntu-touch/staging/ubuntu

com.ubuntu.calculator 2.0.304

It is not possible to calculate anything in the calculator

From calculator logs:
file:///opt/click.ubuntu.com/com.ubuntu.calculator/2.0.304/share/qml/engine/math.js:71: Parse error
qml: [LOG]: Unable to calculate formula : "7774587*36", math.js: SyntaxError: Parse error

Maybe re-produce this with a build of calculator that isn't nearly a year old ;)

You're using r233, please reproduce with r304.

With 304 there is a parse error in math.js and you cannot calculate anything

From the logs:
file:///opt/click.ubuntu.com/com.ubuntu.calculator/2.0.304/share/qml/engine/math.js:71: Parse error
qml: [LOG]: Unable to calculate formula : "7774587*36", math.js: SyntaxError: Parse error

FWIW, works fine on Xenial AMD64 desktop.

Can someone with a xeniel/aarch64/frieza device do a test for me?

This grabs the latest upstream math.js and replaces the one used by the calculator, ninja-style.

adb shell
wget http://cdnjs.cloudflare.com/ajax/libs/mathjs/3.5.0/math.min.js
sudo cp math.min.js /opt/click.ubuntu.com/com.ubuntu.calculator/2.0.304/share/qml/engine/math.js

Close the app, restart it and test again?

It looks something weird happened with database:
file:///opt/click.ubuntu.com/com.ubuntu.calculator/2.0.304/share/qml/ubuntu-calculator-app.qml:366: TypeError: Cannot read property 'dbId' of null
file:///opt/click.ubuntu.com/com.ubuntu.calculator/2.0.304/share/qml/ubuntu-calculator-app.qml:435: TypeError: Cannot read property 'index' of null

which is based on QtQuick.LocalStorage.

getting the same error while trying to pack the calculator using the platform content share. My guess is that some file/library is missing or misplaced. Or a missing evn var.

See bug #1582262 too I filed in May. But this bug is now more up-to-date.

[Timo Jyrinki (timo-jyrinki)]

Not related to platform snap, this is a general issue of something changed in Qt 5.6 versus what the calculator is expecting.
