* ci: refactored CI/CD logic & Makefile
- removed all travis CI emulation environment variables and replaced with:
CI_TAG=<empty>|tag
IS_PULL_REQUEST=false|true
- refactored all OS and architecture-specific decisions to use around standard GOOS/GOARCH values instead of uname/OS
- re-added self-hosted runner for ARMHF (3 replicas)
- added brand new self-hosted runner for ARM64 (3 replicas)
- disabled attempts to publish and sign on forks
- improved integration test log output to better see timings and sub-tests
- print longest tests (unit tests and integration) after each run
- verified that all configurations build successfully on a clone (jkowalski/kopia)
- run make setup in parallel
* testing: fixed tests on ARM and ARM64
- fixed ARM-specific alignment issue
- cleaned up test logging
- fixed huge params warning threshold because it was tripping on ARM.
- reduced test complexity to make them fit in 15 minutes
* object: refactored writer to detect split points before writing
This introduces new primitive that will be moved into splitters
themselves in subsequent commits. I'm doing this in small steps to
ensure we don't regress at any time.
* splitter: refactored TestSplitters test
This is use slow (byte-by-byte) and fast (nextSplitPoint) methods of
determining split points.
Note nextSplitPoint is not implemented by splitters yet, but this
verifies that the test is expecting the right thing.
* object: splitter refactoring - replaced ShouldSplit() with NextSplitPoint() everywhere, still not optimized
* splitter: added additional dimension to splitter_test
We split either in large chunks or one byte at a time to catch
the corner cases in the splitter implementation.
* splitter: optimized splitters using NextSplitPoint primitive
This improves splitter performance by about 40% (buzhash) and makes
it virtually free for FIXED splitter.
- added pooled splitters and ability to reset them without having to recreate
- added support for caller-provided compressor output to be able to pool it
- added pooling of compressor instances, since those are costly
