This adds step-wise caching for the execution of batch specs.
In short, given a batch spec that contains the following
on:
- repository: github.com/sourcegraph/automation-testing
- repository: github.com/sourcegraph-testing/mkcert
steps:
- run: echo "this is step 1" >> caching.txt
container: alpine:3
- run: echo "this is step 2" >> README.md
container: alpine:3
- run: echo "this is step 3" >> README.md
container: alpine:3
outputs:
myOutput:
value: "what is up"
- run: echo "this is step 4" >> caching.txt
if: ${{ eq repository.name "github.com/sourcegraph/automation-testing" }}
container: alpine:3this PR would cause src to cache the results _per step and per repository.
In practice, this means that if we would change the batch spec from the above so it would look like this
steps:
- run: echo "this is step 0" >> caching.txt
container: alpine:3
- run: echo "this is step 1" >> README.md
container: alpine:3
# vvvv LOOK HERE vvv
- run: echo "this is step 2 WITH A CHANGE" >> README.md
container: alpine:3
outputs:
myOutput:
value: "what is up"
- run: echo "this is step 3" >> caching.txt
if: ${{ eq repository.name "github.com/sourcegraph/automation-testing" }}
container: alpine:3and we'd then re-execute the batch spec, the steps 0 and 1 would not need to be re-executed. Only step 2 would need to be re-executed for both repositories and step 3 would only need to be re-executed for both repositories.
