# verify-web-save.sh - Save gate for the web port: a save outlives the page,
|
|
# and each page keeps its own.
|
|
#
|
|
# A web program's SAVES/ is kept in the browser's IndexedDB (the SDL3
|
|
# backend mounts IDBFS there with autoPersist, so each file is written back
|
|
# as it is closed, and again when the page is left), in a folder named after
|
|
# the page: SAVE.html's is /SAVE/SAVES, a store of its own on a site every
|
|
# page shares. SAVE (examples/save) counts its launches in SAVES/runs.dat.
|
|
# Its folder is served with a second copy of its page, OTHER.html, and in
|
|
# one headless Chromium OTHER.html is opened first (its own count, 1), then
|
|
# SAVE.html, given time to write, opened again (reloaded), and given time
|
|
# again: the count SAVE.html then holds must be 2 -- the first launch's 1
|
|
# came back from IndexedDB and the second launch added one; a store shared
|
|
# with OTHER.html would say 3. Each wait covers a cold browser loading the
|
|
# program (4 s once fell short).
|
|
#
|
|
# Usage: scripts/verify-web-save.sh
|
|
# Requires: Chromium, emsdk's node; build/web/bin/SAVE (make web).
