So it looks like we are facing some bad case of a race condition here. We create `running` spawning a process and then we `connectRunning` with its FDs and get a second `proc` process. There `running.stdout` is `id: 1` and had `fd: 16` when `proc.stdin` is `id: 5` with `fd: 16` which seems to be consistent with the expected behavior of those pipes. It means we have two `InputPipe` that shares the same FD. Upon creation they `fillBuffer` https://searchfox.org/mozilla- central/rev/b1cd7e191ac57f8dfe31806be2539e51843c03eb/toolkit/modules/subprocess/subprocess_common.sys.mjs#295. So both enqueues a `read ` call. Somehow the `pollfd.revents` https://searchfox.org/mozilla- central/rev/b1cd7e191ac57f8dfe31806be2539e51843c03eb/toolkit/modules/subprocess/subprocess_unix.worker.js#569 turns `!= 0`for the `InputPipe` of `id:5` before the `id:1` and so we trigger reading the content of the pipe, which is then not available anymore to `id:1`. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1741074 Title: [snap] chrome-gnome-shell extension fails to detect native host connector Status in Mozilla Firefox: In Progress Status in KeePassXC Snap Builds: Unknown Status in chromium-browser package in Ubuntu: Triaged Status in firefox package in Ubuntu: In Progress Status in goopg package in Ubuntu: Confirmed Status in kdeconnect package in Ubuntu: Confirmed Status in plasma-browser-integration package in Ubuntu: Confirmed Bug description: (initially reported at https://forum.snapcraft.io/t/chrome-gnome- shell-does-not-work-with-chromium-snap/3377) See attached screenshot.
