* tart exec: explain that Tart Guest Agent is required
Also handle decrease the connection timeout to 1 second
and provide a hint to the user.
* execute() can be made private
* Include error.localizedDescription
* Introduce "tart exec" command as an alternative to SSH
* Simplify control socket machinery by using NIO async/await primitives
* No reason to print the "vm" object directly, just refer to it as "VM"
* Log to Apple’s Unified Logging System
* Enable clipboard sharing on macOS too
And document which packages need to be installed on these operating
systems.
* We now use Tart Guest Agent

* docs(FAQ): document unsupported DHCP client identifiers
* New section "Resolving the VMs IP with bridged networking"
And a more clearer explanation of what "tart ip" does.
* Remove extraneous space in ` --resolver=arp`
* Better section name
* Add a note about Linux talkativeness
* Explain "talkativeness" a bit better
* tart run: introduce --net-softnet-expose
* --net-softnet-expose: add discussion
* --net-softnet-expose: add a note about Softnet restrictions
...and how to disable them.
* LAN → local network
* Better clarify what --net-softnet does
And how --net-softnet-allow can change that behavior.
* Registry: limit the text output on unexpected status code
* pullBlob(): limit channel read-out on error to 4 KiB
* No need to always read channel until end
This was introduced in https://github.com/cirruslabs/tart/pull/284
because we were blocking in "urlSession(_ session: URLSession, dataTask:
URLSessionDataTask, didReceive data: Data)", which we don't do anymore.
* Fetcher.fetch(): remove "progress" argument as we don't need it anymore
Otherwise we start to periodically get RST's from GitHub, possibly
because of too many connection opens, which has an effect of cancelling
previously received bytes.
These RST's can be observed in tcpdump/Wireshark or Console, emitted
from the libusrtcp.dylib library, com.apple.network subsystem, for the
Tart process:
>tcp_input [C59.1.1.1:3] flags=[R] seq=1805021659, ack=0, win=0 state=CLOSED rcv_nxt=1805021659, snd_una=1752355607
You can also observe the "Received Bytes" in "Activity Monitor" for
the Tart process while pulling ghcr.io/cirruslabs/macos-runner:sequoia,
and this value will periodically decrease.
* DiskV2: avoid allocating zero chunk on each zeroSkippingWrite() call
* Increase hole granularity size from 64 KiB to 4 MiB
* Fetcher: never write to disk, thanks to URLSessionDataDelegate
* Get a fresh instance of executor for each benchmark invocation
And don't pre-initialize all of the executors at once, as this
might reach the maximum number of VMs limit in case we want to
test multiple Tart executors.
* Run benchmarks on Tart with different --root-disk-opts options
* Fix TestTart
* benchmark fio: introduce --prepare command-line argument
To be able to specify --prepare='sudo purge && sync', similarly to
Hyperfine[1].

* Benchmark Tart with --root-disk-opts=caching=cached separately too
* Add Ars Technica recommended benchmarks
* Tart executor: log SSH session standard output and standard error
* Reduce file I/O size from 16 to 10 GB to avoid "No space left on device"
* Remove random writing tests to make space for more read/read-write tests
* Add some "randrw"-style fio benchmarks
* Show latency in benchmark results
* Add sync benchmark and show read/write/sync latency
* README.md: add new benchmark results
* 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
* 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
* Document how to mount the shared directory on Linux at boot time
* Use admonition

* tart create --linux: allow scaling VM down to 1 CPU and 256 MiB
* Revert "tart create --linux: allow scaling VM down to 1 CPU and 256 MiB"
This reverts commit 7a31443eea.
* Check minimum CPU and memory sizes in "tart set"
