* add util.GetFSFromLayers
* GetFSFromImage delegates to GetFSFromLayers
* add FSOpts and FSConfig for GetFSFromLayers
* add tests for GetFSFromLayers
* add gomock for test support
* add mock_v1 for layers
ArgsEscaped according to Docker docs should only be set in Windows
environments: https://docs.docker.com/engine/api/v1.30/
It was causing integration test to fail with following message:
```
FAIL: TestRun/test_Dockerfile_test_metadata (8.48s)
"Diff": {
"Adds": [
"ArgsEscaped: true"
],
"Dels": [
"ArgsEscaped: false"
]
```
However docker 18.xx returns ArgsEscaped: true
whereas docker 19.xx returns ArgsEscaped: false
Hence this patch also adds the docker version check to the integration
to ignore ArgsEscaped being different when 18.xx is used.
* Update cached copy command to return the same result for
files used from context so that cached and uncached copy
commands produce the same cache key
* Update tests for fix
* Add test for cached run command key consistency
* use the cachekey of the src stage rather than the digest
for COPY --from commands as they are reproducible unlike digests
* track digest to cache keys and stage indexes to digest
* add extra debug logging for troubleshooting cachekey building issues
* convert Sha256 hashes to hex encoded strings rather than plain strings
for easier human reading
When using the COPY command, if the source and destination have the same
the file should be skipped rather than copied. This is to prevent the
file from being overwritten and therefore producing an empty file.
fixes#904
The third library moby/buildkit lowers the image alias used in 'FROM .. AS' instruction.
This change fixes this issue by making the resolve of dependencies agnostic to case.
Fixes#592Fixes#770
Store the last cachekey generated for each stage
If the base image for a stage is present in the map of digest
and cachekeys use the retrieved cachekey instead of the base image
digest in the compositecache
Previously we returned a low level file system error when checking for
a cached image. By adding a more human friendly log message and explicit
error handling we improve upon the user experience.
