Lancelot de Ferrière	655a444847	Always allow last-ditch GCs As noted on #7979, we run into OOMs since commit `af32d386b9`. The reason is that the default incremental GC budget is unlimited, which actually doesn't perform incremental GCs. Our settings can lead to situation where the incremental GCs don't actually sweep, thus not freeing memory. SM has a mechanism to avoid OOM anyways with LAST_DITCH GCs, but by default these can only occur ever 30 seconds. Turn this off.

Dunedan	38e4cdc755	Fix password change for certain usernames This fixes the ability for users with uppercase letters in their username to change their passwords, which wasn't possible before on non-Windows platforms. The underlying issue for that is https://github.com/processone/ejabberd/issues/4377 and in addition some inconsistent normalization of usernames in password change requests by gloox. This commit works around that by always using the local JID part as username for password requests, which got the nodeprep string profile already applied. It also fixes a problem that Windows users which were able to change their passwords, weren't able to login afterwards anymore, unless they typed their username in all lowercase in the login form. This was caused by using the all lowercase username as input for the password hash function, instead of using the username in the user supplied case.

Itms	5ffddd0cc4	Implement pipeline for generating patch releases The new patch-release pipeline takes a git branch originating from a release tag, applies the changes since the tag onto the nightly build of the release, and rebuilds the Windows binary. All resulting changes are sent to the bundling pipeline which builds for macOS and creates the tarballs and installers. There will be two instances of the bundles pipeline: the main one will keep tracking the main branch and providing biweekly bundles of the next release, while a new patched-bundles pipeline will be manually used to generate patch releases.

Dunedan	a7694ef8b3	Fix adding port forwardings using UPnP The UPnP implementation included a combination of two subtle bugs, which resulted in failure to create port forwardings every time after the first one. When using UPnP, the internet gateway to create the port forwardings at needs to discovered. As that takes a while, the its root descriptor URL was supposed to be cached after successful discovery in the user config in "network.upnprootdescurl". However, instead of caching the root descriptor URL, the control URL got cached. That caused following requests to the root descriptor URL to fail, as they ended up at the control URL instead. As such requests might also fail when the network topology changed, the code was supposed to fall back to discovering the internet gateway again when the cached one didn't work. However, due to the inner workings of miniupnpc the request using the cached root descriptor URL didn't result in an error, so the new discovery was never triggered. As the wrong value was persisted in the user config there was also no way to get out of this situation again. This commit fixes both of these bugs. As far as I can tell these bugs existed since the introduction of the caching of the root descriptor URL in `0ba25e9968`, which means creating port forwardings using UPnP has been broken since Alpha 15.

Dunedan	ef9ea478ec	Add workaround to turn off nursery size heuristic SpiderMonkey 98 introduced a size heuristic for the nursery GC region (https://phabricator.services.mozilla.com/D136637). As this heuristic uses a wall-clock time duration, it results in a severe performance regression on slower systems for our use case. This commit adds a workaround to turn off that heuristic, by telling SpiderMonkey that a "page load" (something which doesn't have a meaning in the context of pyrogenesis) is in progress, as that heuristic is disabled for page loads.

Ralph Sennhauser	417af009ea	Don't map unknown scancodes to hotkeys Users may generate key presses that don't map to a distinct SDL scancode and will be mapped SDL_SCANCODE_UNKNOWN instead. Using the same ID for unmapped hotkeys means any such key press will execute unset hotkeys. As luck would have it in #7644 this leads to calling "Custom exit to desktop" if the hotkey is unbound as is the default. So simply use a code for unused hotkeys that doesn't map to any SDL scancodes.
