cat	b72dc43bc3	internal/pkg: report dependency graph size ... This is an interesting value to know when profiling. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-21 05:35:28 +09:00
cat	ba75587132	internal/pkg: allow user namespace creation ... No good reason to filter this in the execArtifact container, and the extended filter breaks certain programs. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-21 04:49:25 +09:00
cat	d933234784	internal/pkg: make checksum available to cure ... This enables deduplication by value as implemented in execArtifact. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-19 21:29:56 +09:00
cat	efc90c3221	internal/pkg: deduplicate dependency errors ... This significantly simplifies error reporting for caller. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-17 14:41:00 +09:00
cat	610ee13ab3	internal/pkg: lock on-filesystem cache ... Any fine-grained file-based locking here significantly hurts performance and is not part of the use case of the package. This change guarantees exclusive access to prevent inconsistent state on the filesystem. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-16 18:12:51 +09:00
cat	5936e6a4aa	internal/pkg: parallelise scrub ... This significantly improves scrubbing performance. Since the cache directory structure is friendly to simultaneous access, this is possible without synchronisation. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-16 02:47:59 +09:00
cat	3499a82785	internal/pkg: cache computed identifiers ... This eliminates duplicate identifier computations. The new implementation also significantly reduces allocations while computing identifier for a large dependency tree. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-15 23:30:43 +09:00
cat	088d35e4e6	internal/pkg: optional dependency graph size limit ... This provides a quick check against cyclic dependencies without hurting cure performance. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-14 18:25:46 +09:00
cat	1667df9c43	internal/pkg: zero atime and mtime ... This is significantly more practical than keeping track of them in directory flattening format and setting this in every non-artifact implementation. Only tarArtifact can have meaningful deterministic checksums that are not zero and zeroing them still keeps autotools happy. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-13 01:30:30 +09:00
cat	156dd767ef	internal/pkg: remove typeflag promotion loop ... Expanding this enables sharing of code common between types. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-13 00:33:13 +09:00
cat	5fe166a4a7	internal/pkg: exec prefix verbose output ... This proxies program output through msg with a name and fd prefix. This also avoids introducing additional information to the container via process stdout/stderr. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-12 22:15:01 +09:00
cat	41a8d03dd2	internal/pkg: cure completion verbose messages ... This reports cure completions to the user. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-12 21:56:00 +09:00
cat	610572d0e6	internal/pkg: optionally named static file ... These are generally for generating configuration files or build scripts, naming them is quite useful. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-12 04:34:50 +09:00
cat	29951c5174	internal/pkg: caller-supplied reporting name for exec ... This does not have a reasonable way of inferring the underlying name. For zero value it falls back to base of executable pathname. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-12 04:17:47 +09:00
cat	91c3594dee	internal/pkg: append user-facing name in messages ... This makes verbose messages much more useful. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-12 03:53:19 +09:00
cat	7ccc2fc5ec	internal/pkg: exec with specific timeout ... This change also updates the documentation of NewExec. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-11 17:46:04 +09:00
cat	63e137856e	internal/pkg: do not discard the result of compact ... This result was mistakenly unused resulting in incorrect identifiers for artifacts with duplicate dependencies. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-11 04:40:24 +09:00
cat	da3848b92f	internal/pkg: compare interfaces for host net ... An upcoming improvement in the container init makes the current host net check return the same result for both cases. This change Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-11 00:30:32 +09:00
cat	34cb4ebd3b	internal/pkg: pass context to file cure ... This removes the left over embedded contexts. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-09 05:31:38 +09:00
cat	f712466714	internal/pkg: move dependency flooding to cache ... This imposes a hard upper limit to concurrency during dependency satisfaction and moves all dependency-related code out of individual implementations of Artifact. This change also includes ctx and msg as part of Cache. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-09 05:20:34 +09:00
cat	f2430b5f5e	internal/pkg: use short wait delay ... The cure is condemned at the point of cancellation and all of its state is destroyed by the deferred cleanup, so it makes little sense to wait for it much. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-08 18:58:51 +09:00
cat	863e6f5db6	internal/pkg: use correct artifact count ... This updates buffer sizes and counters to use correct total artifact count. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-08 08:45:37 +09:00
cat	23df2ab999	internal/pkg: place ephemeral upperdir in tmp ... This enables the use of directories made writable this way as scratch space. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-08 08:23:16 +09:00
cat	7bd4d7d0e6	internal/pkg: support explicit overlay mount ... This removes all but the /work/ auto overlay behaviour and enables much greater flexibility. This also renames ExecContainerPath to ExecPath so it is easier to type. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-08 07:55:09 +09:00
cat	b3c30bcc51	internal/pkg: set container WaitDelay ... This prevents a container from blocking forever after context is canceled. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-08 06:23:57 +09:00
cat	38059db835	internal/pkg: make tar temporary directory writable ... This allows it to be renamed to work directory. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-08 04:32:14 +09:00
cat	409fd3149e	internal/pkg: reserve kind range ... This is useful for custom implementations of Artifact. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-08 01:21:51 +09:00
cat	4eea136308	internal/pkg: do not connect stdin ... This introduces external state when verbose. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-07 23:17:58 +09:00
cat	c86ff02d8d	internal/pkg: tar optional file ... This allows tar to take a single-file directory Artifact as input. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-07 22:16:26 +09:00
cat	e8dda70c41	internal/pkg: return reader for files ... This improves efficiency for cache hits. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-07 21:36:47 +09:00
cat	7ea4e8b643	internal/pkg: support tarball compressed via bzip2 ... Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-07 20:18:28 +09:00
cat	5eefebcb48	internal/pkg: reject entry types disallowed in the cache ... These are not encoded in the format, they are rejected here to serve as a check for cache since checksum is computed for every directory. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-07 03:22:44 +09:00
cat	8e08e8f518	internal/pkg: automatic overlay mount on work ... This directly submits the upperdir to cache. It is primarily used in bootstrapping where tools are limited and should not be used unless there is a very good reason to. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-07 03:14:33 +09:00
cat	54da6ce03d	internal/pkg: respect mount order for overlay temp ... Setting it up after everything else prevents covering files in /tmp. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-07 01:03:49 +09:00
cat	3a21ba1bca	internal/pkg: implement file artifact ... This is an Artifact implementing File, backed by a constant, caller-supplied byte slice. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-07 00:39:29 +09:00
cat	45301559bf	internal/pkg: fail on empty output directory ... This works around the fact that execArtifact always creates the work directory when setting up the bind mount. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-07 00:04:32 +09:00
cat	0df87ab111	internal/pkg: automatic overlay mount on tmp ... This sets up the last Artifact to target /tmp as a writable overlay mount backed by the host side temp directory. This is useful for an Artifact containing source code to be built for another Artifact for example. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-06 23:45:08 +09:00
cat	aa0a949cef	internal/pkg: do not clear execute bit ... Only write should be cleared here, clearing execute causes execArtifact to be unable to start anything since no Artifact is able to produce an executable file. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-06 22:31:44 +09:00
cat	ce0064384d	internal/pkg: automatic overlay mount on root ... This makes it possible to use an Artifact as root without arranging for directory creation in the Artifact ahead of time. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-06 22:19:47 +09:00
cat	53d80f4b66	internal/pkg/testdata: check network ... This validates hostNet state. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-06 21:32:10 +09:00
cat	156096ac98	internal/pkg: known checksum exec artifact ... This optionally attaches an output checksum to an execArtifact and enables host networking for the resulting container. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-06 20:58:34 +09:00
cat	ceb75538cf	internal/pkg: update http checksum signature ... This was using the old pre-KnownChecksum function signature. It did not affect correctness since httpArtifact performs internal validation to avoid the strict mode vfs roundtrip, but it prevented content-addressed cache hits. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-06 18:24:31 +09:00
cat	0741a614ed	internal/pkg: relocate testtool workaround ... This can be reused in other test cases. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-06 18:06:56 +09:00
cat	e7e9b4caea	internal/pkg: exec nil path check during cure ... This results in os.ErrInvalid instead of a panic, which hopefully improves user experience. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-06 17:46:12 +09:00
cat	f6d32e482a	internal/pkg: ensure parent for non-directory entries ... This works around streams containing out of order entries. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-06 05:55:24 +09:00
cat	79adf217f4	internal/pkg: implement exec artifact ... This runs a program in a container environment. Artifacts can be made available to the container, they are cured concurrently and mounted in order. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-06 05:05:34 +09:00
cat	8efffd72f4	internal/pkg: destroy temp during deferred cleanup ... This avoids missing the cleanup when cure returns an error. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-06 04:24:54 +09:00
cat	86ad8b72aa	internal/pkg: expose cure through cure context ... This allows a curing Artifact to cure Artifact it depends on. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-06 01:04:06 +09:00
cat	e91049c3c5	internal/pkg: pass cure context as single value ... This cleans up the function signature and makes backwards compatible API changes possible. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-06 00:56:49 +09:00
cat	3d4d32932d	internal/pkg: verify checksum after uneventful scrub ... This checks that scrub did not condemn any entry without reporting it. Signed-off-by: Ophestra <cat@gensokyo.uk>	2026-01-05 22:54:16 +09:00
