Firefox extension stops working after entering search term

[tomwassenberg]

After upgrading to v1.30.1, the Firefox extension stops responding after I enter a few characters as a search term.

CPU usage rises dramatically and on one of my machines (Windows, Fx 62.0b17) the addon window doesn't re-appear when clicking on the icon. On Linux (Fx 61.0.1) Firefox locks up entirely and has to be force quit.

I can reproduce the issues on v1.30.0 and v1.30.1 of the Firefox extension.

Tested on Windows 10 with Firefox 62.0b17 and Linux Mint with Firefox 61.0.1.

How many items are in the vault? Can you also reproduce this in the web vault?

[tomwassenberg]

Thanks for the instant reply!

Same thing happens with the web vault. Vault contains approximately 500 items.

Ok. Sounds like there is some item that is causing this same bug I discovered in Lunr: olivernn/lunr.js#368

Try performing your search query with a preceding > and see if the same issue occurs.

For example, >something instead of something.

[tomwassenberg]

Looks like you're right, preceding the query with > seems to resolve the issue.

Ok, it's definitely the bug I linked above which seems to have issues with wildcards, which are used by default when not doing a > search. Would you happen to have a few minutes to help me try to debug this further in your vault? I am available in our dev chatroom here and would like to try to run through some steps to figure out which item in your vault is causing the problem.

@tomwassenberg I pushed 1.30.2 which reduces regular searching to only trailing wildcards for now. Can you update and try it to see if the problem with regular searching is resolved?

[kspearrin]

It was also pushed to the web vault.

[tomwassenberg]

Yes, 1.30.2 (+ web) fixes the problem with regular searches :)

Closing this for now. Tracking at olivernn/lunr.js#368
