Ophestra	7548a627e5	internal/pkg: delete stale done channels ... There is no reason to keep these around. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-05 02:12:34 +09:00
Ophestra	b98d27f773	internal/pkg: expand single directory tarball ... This enables much cleaner use of their output without giving up any meaningful data. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-05 01:43:23 +09:00
Ophestra	f3aa31e401	internal/pkg: temporary scratch space for cure ... This allows for more flexibility during implementation. The use case that required this was for expanding single directory tarballs. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-05 01:39:18 +09:00
Ophestra	4da26681b5	internal/pkg: compute http identifier from url ... The previous implementation exposes arbitrary user input to the cache as an identifier, which is highly error-prone and can cause the cache to enter an inconsistent state if the user is not careful. This change replaces the implementation to compute identifier late, using url string as params. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-05 00:43:21 +09:00
Ophestra	4897b0259e	internal/pkg: improve artifact interface ... This moves all cache I/O code to Cache. Artifact now only contains methods for constructing their actual contents. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-05 00:01:23 +09:00
Ophestra	d6e4f85864	internal/pkg: ignore typeflag 'g' ... Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-04 12:46:56 +09:00
Ophestra	3eb927823f	internal/pkg: create symlinks for files ... These are much easier to handle than hard links and should be just as transparent for this use case. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-04 01:48:53 +09:00
Ophestra	d76b9d04b8	internal/pkg: implement tar artifact ... This is useful for unpacking tarballs downloaded from the internet. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-04 01:34:30 +09:00
Ophestra	fa93476896	internal/pkg: override working directory perms ... This must be writable to enable renaming, and the final result is conventionally read-only alongside the entire directory contents. This change overrides the permission bits as part of Store. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-04 00:55:52 +09:00
Ophestra	bd0ef086b1	internal/pkg: enable cache access during store ... This is still not ideal as it makes entry into Store sequential. This will be improved after more usage code is written. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-04 00:39:14 +09:00
Ophestra	05202cf994	internal/pkg: pass context in request wrapper ... This method is for the most common use case, and in actual use there will always be an associated context. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-03 23:53:52 +09:00
Ophestra	40081e7a06	internal/pkg: implement caching for directories ... This works on any directories and should be robust against any bad state the artifact curing process might have failed at. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-03 22:54:46 +09:00
Ophestra	863d3dcf9f	internal/pkg: wrap checksum string encoding ... This wraps base64.URLEncoding.EncodeToString for cleaner call site. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-03 22:03:25 +09:00
Ophestra	8ad9909065	internal/pkg: compute identifier from deps ... This provides infrastructure for computing a deterministic identifier based on current artifact kind, opaque parameters data, and optional dependency kind and identifiers. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-03 21:26:25 +09:00
Ophestra	deda16da38	internal/pkg: create work directory ... This is used for artifacts that cure into directories. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-03 20:56:11 +09:00
Ophestra	55465c6e72	internal/pkg: optionally validate flat pathnames ... This makes the decoder safe against untrusted input without hurting performance for a trusted stream. This should still not be called against untrusted input though. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-03 18:59:18 +09:00
Ophestra	ce249d23f1	internal/pkg: implement http artifact ... This is useful for downloading source tarballs from the internet. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-03 15:29:58 +09:00
Ophestra	dd5d792d14	go: 1.25 ... Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-03 15:25:28 +09:00
Ophestra	d15d2ec2bd	internal/pkg: relocate cache test helper ... This is useful for other tests that need a cache instance. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-02 16:08:43 +09:00
Ophestra	3078c41ce7	internal/pkg: encode entry in custom format ... The fact that Gob serialisation is deterministic is an implementation detail. This change replaces Gob with a simple custom format. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-02 15:39:42 +09:00
Ophestra	e9de5d3aca	internal/pkg: implement caching for files ... This change contains primitives for validating and caching single-file artifacts. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-02 12:57:19 +09:00
Ophestra	993afde840	dist: install sharefs ... This also removes the deprecated hpkg program. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-02 00:57:51 +09:00
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. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-27 22:14:33 +09:00
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	3d720ada92	container: optionally allow orphan ... This is required for the typical daemonise use case. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-27 09:12:02 +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	54712e0426	nix: set noatime on sharefs ... Could improve performance, atime is not useful for this filesystem anyway. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-26 05:34:05 +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	dce5839a79	nix: do not restart sharefs ... This avoids disrupting running containers. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-26 04:12:14 +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	ea815a59e8	nix: disable source fortification in devShell ... This generates warnings when compiling without optimisation. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-21 02:22:28 +09:00
Ophestra	28a8dc67d2	internal/pipewire: raise Core::Sync timeout ... Hopefully relieves spurious failures on a very overloaded system. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-19 00:49:33 +09:00
Ophestra	ec49c63c5f	internal/pipewire: EPOLL_CTL_ADD instead of EPOLL_CTL_MOD ... Implementation is no longer tied down by the limitations of SyscallConn. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-19 00:43:44 +09:00
Ophestra	5a50bf80ee	internal/pipewire: hold socket fd directly ... The interface provided by net is not used here and is a leftover from a previous implementation. This change removes it. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-19 00:28:24 +09:00
Ophestra	ce06b7b663	internal/pipewire: inform conn of blocking intent ... The interface does not expose underlying kernel notification mechanisms. This change removes the need to poll in situations were the next call might block. This is made cumbersome by the SyscallConn interface left over from a previous implementation, it will be replaced in a later commit as the current implementation does not make use of any net.Conn methods other than Close. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-19 00:00:33 +09:00
Ophestra	08bdc68f3a	internal/pipewire: sendmsg/recvmsg errors are fatal ... When returned wrapped as a syscall error, these are impossible to recover from, so wrap them as a fatal error. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-18 23:33:12 +09:00
Ophestra	8cb0b433b2	release: 0.3.3 ... Signed-off-by: Ophestra <cat@gensokyo.uk> v0.3.3	2025-12-15 20:34:45 +09:00
Ophestra	767f1844d2	test: check shim private dir cleanup ... This asserts that no shim private dir was left behind after all containers terminate. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-15 20:30:19 +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	2e80660169	internal/outcome: look up pipewire-pulse path ... This is for setting up the pipewire-pulse container in shim, for #29. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-12-15 12:38:39 +09:00
