To make sure we won't prune then immediately after. Useful for when scenarios similar to Cirrus CLI when we make sure that several images are up-to-date before every request for task execution.
* Revert "Lowercase `tart.app` (#751)"
This reverts commit a9e2a19015.
* Optimize DiskV2 deduplication logic
In case we cloned `disk.img` from a local image, check if data at offset has the expected contents already.
* Hole punch only if needed
* Calculate hash only if needed
* subdataChunks optimization
* Reapply "Lowercase `tart.app` (#751)"
This reverts commit e74e9c845a.
* format
* Save at least 1GB on deduplication logic
* Build separately
* Revert "subdataChunks optimization"
This reverts commit e59382aeba.
* Another optimization
* Removed debug log
* reformat
* Revert "Hole punch only if needed"
This reverts commit 8c569fc5
* VZDiskImageSynchronizationMode's "description" field is a dead code
* Re-use the VZDiskImageSynchronizationMode extension
* tart run: replace --sync with --root-disk-opts
* VM: support root disk synchronization mode on macOS
* Support setting root disk synchronization mode
Adds a new VMConfig parameter (tart get / tart set) called 'sync' which
can be set to 'full' (default), 'fsync', or 'none', corresponding with
the values of VZDiskImageSynchronizationMode and allowing a tradeoff
between data integrity and speed.
* Remove unused import
* Fix formatting
* Make root disk sync behaviour a commandline option
* tart pull: try to re-use APFS blocks by cloning the base image
* Punch a hole when a zero chunk is detected
* Properly retrieve errno when hole punching operation fails
* tart pull: do not retry on RuntimeError
* Ensure that the holes we're about to punch are FS block size-aligned
* VMDirectory: remove unused static variables
* tart pull: log if we've found an image to deduplicate against
* Do not prematurely read contents from disk
* Only consider candidates with deduplicatedBytes more than 0
* APFS reuse UX/DX improvements (#870)
* Show how much deduplication happening
Improvement to the APFS deduplication logic which checks whether a disk image file `mayShareFileContent` with some other file, and then we put a custom attribute to track the deduplication since there is no way to get this information from APFS itself.
It's not 100% accurate but given that OCI cache is immutable the actual disk usage can only be lover than that.
* Use string attribute
* Update Sources/tart/URL+Prunable.swift

This is accomplished by saving the OCI VM image manifests on "tart pull"
in "manifest.json" file and then using them on successive "tart pull"'s
to find the best candidate that results in the most de-duplication,
measured in bytes.
* Support remote VM names in --disk command-line argument
* tart set: introduce "--disk" to support replacing VM's disk contents
* Complete the code comment
For macOS this brings up a dialog, asking the user if they are sure
they want to shut down, which makes this less useful for automated
graceful shutdowns, but it may behave better on Linux, and there
might be ways to instruct macOS to not ask the user, so it's still
a nice feature, and aligns with the SIGUSR1 for suspend, and SIGINT
for non-graceful shutdown.
* Drop Monterey Support
People will still be able to run and SSH into Monterey VMs or use VNC but pointing devices/keyboard won't work.
Fixes#841
* Fixed x86 build
The latest release has this error:
> error: Project not found. Please check that you entered the project and organization slugs correctly.
Which seems indicating that Auth is broken and we are getting 404? In the Sentry Settings I didn't find any token which I find strange. So I created one and re-encrypted.
