Ophestra	c9cd16fd2a	cmd/sharefs: prepare directory early ... This change also checks against filesystem daemon running as root early. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-27 23:17:02 +09:00
Ophestra	e42ea32dbe	nix: configure sharefs via fileSystems ... Turns out this did not work because in the vm test harness, virtualisation.fileSystems completely and silently overrides fileSystems, causing its contents to not even be evaluated anymore. This is not documented as far as I can tell, and is not obvious by any stretch of the imagination. The current hack is cargo culted from nix-community/impermanence and hopefully lasts until this project fully replaces nix. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-27 23:14:08 +09:00
Ophestra	e7982b4ee9	cmd/sharefs: create directory as root ... This optional behaviour is required on NixOS as it is otherwise impossible to set this up: systemd.mounts breaks startup order somehow even though my unit looks identical to generated ones, fileSystems does not support any kind of initialisation or ordering other than against other mount points.

Ophestra	ef1ebf12d9	cmd/sharefs: handle mount -t fuse.sharefs ... This should have been handled in a custom option parsing function, but that much extra complexity is unnecessary for this edge case. Honestly I do not know why libfuse does not handle this itself. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-27 20:49:27 +09:00
Ophestra	775a9f57c9	cmd/sharefs: check option parsing behaviour ... This change makes it possible to check parseOpts behaviour as part of Go tests. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-27 17:33:12 +09:00
Ophestra	2f8ca83376	cmd/sharefs: containerise filesystem daemon ... This replaces the forking daemonise libfuse function which prevents Go callbacks from calling into the runtime. This also enforces least privilege on the daemon process. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-27 10:16:35 +09:00
Ophestra	2e5362e536	cmd/sharefs: opaque setup state ... This allows unrestricted use of the type system and prepares setup code for cross-process initialisation. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-27 04:14:00 +09:00
Ophestra	6d3bd27220	cmd/sharefs: expand fuse_main ... This change should not change behaviour other than making output more consistent. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-27 02:30:28 +09:00
Ophestra	a27305cb4a	cmd/sharefs: improve help message ... This improves consistency with the fuse_main help message. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-27 02:20:41 +09:00
Ophestra	0e476c5e5b	cmd/sharefs: allocate sharefs_private early ... This also removes global state used by sharefs_init. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-26 08:08:41 +09:00
Ophestra	b77c1ecfdb	cmd/sharefs/test: check option handling ... This verifies behaviour related to setuid/setgid when starting as root. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-26 05:28:45 +09:00
Ophestra	d597592e1f	cmd/sharefs: rename fuse-helper to fuse-operations ... This is not really just library wrapper functions, but instead implements the callbacks, so fuse-operations makes more sense. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-26 03:19:32 +09:00
Ophestra	056f5b12d4	cmd/sharefs: move translate_pathname body to macro wrapper ... This is never called directly anywhere and it is simple enough to be included in the macro. This avoids passing the pointer around and dereferencing errno location, resulting in over 5% increase in throughput on the clang build. No change in the gcc build though. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-26 02:10:59 +09:00
Ophestra	da2bb546ba	cmd/sharefs: remove readlink ... This filesystem does not support symbolic links, so readlink is not useful, and unreachable in this case because of the check in getattr. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-25 06:00:58 +09:00
Ophestra	7bfbd59810	cmd/sharefs: implement shared filesystem ... This is for passing files between applications, similar to android /sdcard. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-25 05:13:02 +09:00
Ophestra	54610aaddc	internal/outcome: expose pipewire via pipewire-pulse ... This no longer exposes the pipewire socket to the container, and instead mediates access via pipewire-pulse. This makes insecure parts of the protocol inaccessible as explained in the doc comment in hst. Closes #29. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-15 12:57:06 +09:00
Ophestra	ebc67bb8ad	nix: update flake lock ... NixOS 25.11 introduces a crash in cage and an intermittent crash in foot. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-12 08:39:55 +09:00
Ophestra	d5fb179012	cmd/hakurei: exec instead of fork/exec from shell ... There is no reason to keep the shell process around. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-08 22:29:41 +09:00
Ophestra	87781c7658	treewide: include PipeWire op and enforce PulseAudio check ... This fully replaces PulseAudio with PipeWire and enforces the PulseAudio check and error message. The pipewire-pulse daemon is handled in the NixOS module. Closes #26. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-08 08:53:04 +09:00
Ophestra	422efcf258	hst: check for insecure PulseAudio enablement ... This is currently still a noop, but required for #26. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-08 03:13:02 +09:00
Ophestra	104eeecf65	cmd/hakurei: add pipewire flag ... This is for "run" command, formerly permissive defaults behaviour. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-08 02:39:55 +09:00
Ophestra	1931b54600	hst: add pipewire flag ... These are for #26. None of them are implemented yet. This fixes up test cases for the change to happen. Existing source code and JSON configuration continue to have the same effect. Existing flags get its EPulse bit replaced by EPipeWire.

Ophestra	3afca2bd5b	internal/wayland: expose WAYLAND_VERSION ... This might be useful troubleshooting information. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-11-17 01:46:01 +09:00
Ophestra	a91920310d	internal: relocate packages ... Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-11-15 13:58:34 +09:00
Ophestra	16e674782a	cmd/hakurei: reorder show entries ... This order semantically makes more sense and generally looks tidier. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-11-14 22:14:49 +09:00
Ophestra	be0e387ab0	internal/info: relocate from internal ... This is cleaner and makes more sense. The longer LDFLAGS was never a valid concern since it is always inserted by a script. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-11-13 07:29:46 +09:00
Ophestra	abeb67964f	treewide: document linkname uses ... These provide justification for each use of linkname. Poorly thought out uses of linkname are removed. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-11-13 07:14:16 +09:00
Ophestra	bf5d10743f	treewide: import internal/system ... For #24. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-11-13 01:22:47 +09:00
Ophestra	d7e0104ae4	treewide: reject impossible user-supplied fd ... These are all trusted user input, however this check reduces the likelihood of hard to debug errors. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-11-10 20:31:26 +09:00
Ophestra	bb92e3ada9	cmd/hakurei: expose current instance identifier ... This writes the 16-byte instance identifier to file descriptor specified by --identifier-fd if set, and closes the file. This enables safely obtaining the new instance's identifier. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-11-10 07:52:35 +09:00
Ophestra	9fd97e71d0	treewide: fit test untyped int literals in 32-bit ... This enables hakurei test suite to run on 32-bit targets. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-11-05 20:13:19 +09:00
Ophestra	cb9ebf0e15	hst/grp_pwd: specify new uid format ... This leaves slots available for additional uid ranges in Rosa OS. This breaks all existing installations! Users are required to fix ownership manually. Closes #18. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-11-04 08:24:41 +09:00
Ophestra	9a2a7b749f	cmd/hakurei/print: handle nil config ... There is nothing to print in this case, and such a nil check is missing. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-11-03 02:20:18 +09:00
Ophestra	ec5cb9400c	cmd/hpkg/test: print share directory ... This is more useful now that state is tracked here. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-11-03 01:51:57 +09:00
Ophestra	ae66b3d2fb	message: rename NewMsg to New ... Should have done this when relocating this from container. Now is a good time to rename it before v0.3.x. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-11-03 01:49:27 +09:00
Ophestra	24435694a5	hst/config: make identifier omitempty ... This is an optional field. Serialise it as such. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-11-03 01:23:15 +09:00
Ophestra	1c168babf2	cmd/hakurei/print: use new store interface ... This removes the final uses of the compat interfaces. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-11-03 01:19:16 +09:00
Ophestra	0e5ca74b98	cmd/hakurei/print: serialise array for ps ... Wanted to do this for a long time, since the key is redundant. This also makes it easier to migrate to the new store interface. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-11-02 16:37:08 +09:00
Ophestra	23ae7822bf	cmd/hakurei/parse: use new store interface ... This greatly reduces overhead. The iterator also significantly cleans up the usage code. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-11-02 16:00:41 +09:00
Ophestra	7c3c3135d8	internal/outcome: track state in TMPDIR ... The SharePath is a more stable path than RunDirPath, since it is available all the time and should remain consistent. This also fits better into the intended use case of XDG_RUNTIME_DIR. Closes #17. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-11-02 12:40:58 +09:00
Ophestra	b25ade5f3d	internal/store: rename compat interface ... The new store implementation will be exported as Store. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-10-30 18:53:59 +09:00
Ophestra	ebdcff1049	internal/store: rename from state ... This reduces collision with local variable names, and generally makes sense for the new store package, since it no longer specifies the state struct. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-10-30 18:43:55 +09:00
Ophestra	a0b4e47acc	internal/outcome: rename from app ... This is less ambiguous, and more accurately describes the purpose of the package. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-10-29 04:33:13 +09:00
Ophestra	a52f7038e5	internal/env: relocate from app ... This package is much cleaner to stub independently, and makes no sense to lump into app. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-10-29 04:11:49 +09:00
Ophestra	4a463b7f03	internal/app/state: use absolute pathnames ... This is less error-prone and fits better into internal/app which already uses check.Absolute for all pathnames. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-10-26 03:41:19 +09:00
Ophestra	546b00429f	treewide: update doc comments ... Some internal/app/state types were relocated to hst as part of the API. This change updates doc comments referring to them. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-10-26 03:00:04 +09:00
Ophestra	470e545d27	internal/app/state: use internal/lockedfile ... This is a pretty solid implementation backed by robust tests, with a much cleaner interface. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-10-25 21:29:24 +09:00
Ophestra	7de593e816	cmd/hakurei: short identifier from lower half ... The upper half is now a nanosecond timestamp. Lower half is still random bytes, so use lower half for short identifier. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-10-24 00:47:39 +09:00
Ophestra	2442eda8d9	hst/instance: embed config struct ... This makes the resulting json easier to parse since it can now be deserialised into the config struct. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-10-24 00:42:16 +09:00
Ophestra	05488bfb8f	hst/instance: store priv side pid ... This can receive signals, so is more useful to the caller. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-10-23 23:19:55 +09:00
