Issue with very large families

[Tb8854]

Hello,

When I go for a large family (which works in smaller chunks) I have the following error

When I run the following

kingraph myfamily_all.yml -F png > myfamily_all.png

I get the following result.

Cannot enlarge memory arrays. Either (1) compile with  -s TOTAL_MEMORY=X  with X higher than the current value 16777216, (2) compile with  -s ALLOW_MEMORY_GROWTH=1  which adjusts the size at runtime but prevents some optimizations, (3) set Module.TOTAL_MEMORY to a higher value before the program runs, or if you want malloc to return NULL (0) instead of this abort, compile with  -s ABORTING_MALLOC=0

If this abort() is unexpected, build with -s ASSERTIONS=1 which can give more information.

Adding options (1), (2) or (3) has no effect. The family isn't that big - around 200 lines and 400-500 people in 10 houses.

Any advice appreciated.

I also have this issue.

It looks like it's a problem with viz.js. Temporary workaround is to use dot

kingraph family.yaml --format=dot > family.dot  && dot -Tsvg family.dot > family.svg

Thanks for the help debugging the issue!

This seems to be worth at least documenting somewhere. Let's see if updating viz.js would help too.

[janisz]

We can try increase totalMemory like proposed here mdaines/viz-js#89 or heere mdaines/viz-js#23

In case anyone else is curious - I fixed this by changing the totalMemory variable in viz.js with this line:
sudo sed -i '' -e 's/|16777216/|1677721600/' viz.js - that allows viz to use ~1.6GB

for windows, if installed globally

npm list -g

C:\Users\user\AppData\Roaming\npm
└── kingraph@0.1.0

then open
C:\Users\user\AppData\Roaming\npm\node_modules\kingraph\node_modules\viz.js

and replace 16777216 to, as example, 1677721600
