1740353 - Configure hunspell rlbox sandbox so AMO dictionaries have a smaller footprint

Status: RESOLVED FIXED

(Core :: Spelling checker, enhancement, P3)

Description

[Shravan Narayan]

Initially in Bug 1739669, we had decided to use a heuristic of 7x the size of the dictionary, rounded to the power of two as a rough heuristic on how much memory hunspell takes. to spell check. Thus one of the larger dictionaries on addons.mozilla, which is the bg locale which is 8.6mb on disk would need a 64mb rlbox wasm sandbox.

However, the largest addons.mozilla dictionary https://addons.mozilla.org/en-US/firefox/addon/dico-ortografic-oc-lengadocian/ is about 9.53 mb on file, and does run fine in a 64mb sandbox, even though the heuristic says we need a 128mb sandbox. To reduce the memory necessary, we modify this heuristic to 6.4x. Thus any dictionary upto 10mb should fit inside the sandbox.
