Cache multiple paths and add glob pattern support (#212)
* Allow for multiple line-delimited paths to cache

* Add initial minimatch support

* Use @actions/glob for pattern matching

* Cache multiple entries using --files-from tar input

remove known failing test

Quote tar paths

Add salt to test cache

Try reading input files from manifest

bump salt

Run test on macos

more testing

Run caching tests on 3 platforms

Run tests on self-hosted

Apparently cant reference hosted runners by name

Bump salt

wait for some time after save

more timing out

smarter waiting

Cache in tmp dir that won't be deleted

Use child_process instead of actions/exec

Revert tempDir hack

bump salt

more logging

More console logging

Use filepath to with cacheHttpClient

Test cache restoration

Revert temp dir hack

debug logging

clean up cache.yml testing

Bump salt

change debug output

build actions

* unit test coverage for caching multiple dirs

* Ensure there's a locateable test folder at homedir

* Clean up code

* Version cache with all inputs

* Unit test getCacheVersion

* Include keys in getCacheEntry request

* Clean import orders

* Use fs promises in actionUtils tests

* Update import order for to fix linter errors

* Fix remaining linter error

* Remove platform-specific test code

* Add lerna example for caching multiple dirs

* Lerna example updated to v2

cache

This action allows caching dependencies and build outputs to improve workflow execution time.

GitHub Actions status

Documentation

See "Caching dependencies to speed up workflows".

Usage

Pre-requisites

Create a workflow .yml file in your repositories .github/workflows directory. An example workflow is available below. For more information, reference the GitHub Help Documentation for Creating a workflow file.

Inputs

  • path - A directory to store and save the cache
  • key - An explicit key for restoring and saving the cache
  • restore-keys - An ordered list of keys to use for restoring the cache if no cache hit occurred for key

Outputs

  • cache-hit - A boolean value to indicate an exact match was found for the key

See Skipping steps based on cache-hit for info on using this output

Example workflow

name: Caching Primes

on: push

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v1

    - name: Cache Primes
      id: cache-primes
      uses: actions/cache@v1
      with:
        path: prime-numbers
        key: ${{ runner.os }}-primes

    - name: Generate Prime Numbers
      if: steps.cache-primes.outputs.cache-hit != 'true'
      run: /generate-primes.sh -d prime-numbers

    - name: Use Prime Numbers
      run: /primes.sh -d prime-numbers

Implementation Examples

Every programming language and framework has its own way of caching.

See Examples for a list of actions/cache implementations for use with:

Cache Limits

A repository can have up to 5GB of caches. Once the 5GB limit is reached, older caches will be evicted based on when the cache was last accessed. Caches that are not accessed within the last week will also be evicted.

Skipping steps based on cache-hit

Using the cache-hit output, subsequent steps (such as install or build) can be skipped when a cache hit occurs on the key.

Example:

steps:
  - uses: actions/checkout@v2

  - uses: actions/cache@v1
    id: cache
    with:
      path: path/to/dependencies
      key: ${{ runner.os }}-${{ hashFiles('**/lockfiles') }}

  - name: Install Dependencies
    if: steps.cache.outputs.cache-hit != 'true'
    run: /install.sh

Note: The id defined in actions/cache must match the id in the if statement (i.e. steps.[ID].outputs.cache-hit)
