Makes clean shutdown with systemd actually work.
I've also made superqemu version a SemVer thing so that we don't need to bump it as often, only on a major or minor bump.
- moved superqemu's "QemuDisplay" here; the VNC VM and Qemu both share it (and it has been renamed to a less goofy dumb name)
- VNC VM has been heavily refactored to just use the VNC display we have (this means only one source of truth, less bugs, and it's generally just Better to share the code imho). this means that future plans to abstract this further (or implement the client in cvm-rs in general) won't cause any explosions, or require duplicate effort
- vms are now in src/vm/... just better organization
- superqemu doesn't manage a display anymore (or care about it, other than making sure the socket is unlinked on stop). Instead now it provides info for us to setup our own VNC client. This is also why we provide our own shim interface
This currently relies on a alpha version of superqemu.
Before this is merged into cvmts main I will publish a stable tag and point cvmts to that new version
We publish them now, so let's use them in cvmts!
Additionally, this removes the 'shared' module entirely, since it has little purpose anymore. The logger is replaced with pino (because superqemu uses pino for logging itself).
It sucked. The new one is using Sans I/O principles, so it does not
directly do I/O or talk to a net.Socket directly (instead, QemuVM implements
the layer to do I/O). This means in the future this library could actually
be tested, but for now, I'm not bothering with that.
There's also some other cleanups that were bothering me.
doesn't really need to be two seperate libraries. also preperation for other funnies
the build script has been replaced with a much saner justfile which uses much saner "yarn workspace" invocations instead of blindly cding all over the place
In short:
- cvmts is now bundled/built via parcel and inside of a npm/yarn workspace with multiple nodejs projects
- cvmts now uses the crusttest QEMU management and RFB library (or a fork, if you so prefer).
- cvmts does NOT use node-canvas anymore, instead we opt for the same route crusttest took and just encode jpegs ourselves from the RFB provoded framebuffer via jpeg-turbo. this means funnily enough sharp is back for more for thumbnails, but actually seems to WORK this time
- IPData is now managed in a very similar way to the original cvm 1.2 implementation where a central manager and reference count exist. tbh it wouldn't be that hard to implement multinode either, but for now, I'm not going to take much time on doing that.
this refactor is still incomplete. please do not treat it as generally available while it's not on the default branch. if you want to use it (and report bugs or send fixes) feel free to, but while it may "just work" in certain situations it may be very broken in others.
(yes, I know windows support is partially totaled by this; it's something that can and will be fixed)
