fix: continue jobs + steps after failure (#840) * fix: continue jobs + steps after failure To allow proper if expression handling on jobs and steps (like always, success, failure, ...) we need to continue running all executors in the prepared chain. To keep the error handling intact we add an occurred error to the go context and handle it later in the pipeline/chain. Also we add the job result to the needs context to give expressions access to it. The needs object, failure and success functions are split between run context (on jobs) and step context. Closes #442 Co-authored-by: Björn Brauer <zaubernerd@zaubernerd.de> * style: correct linter warnings Co-authored-by: Björn Brauer <zaubernerd@zaubernerd.de> * fix: job if value defaults to success() As described in the documentation, a default value of "success()" is applied when no "if" value is present on the job. https://docs.github.com/en/actions/learn-github-actions/expressions#job-status-check-functions Co-authored-by: Markus Wolf <mail@markus-wolf.de> * fix: check job needs recursively Ensure job result includes results of previous jobs Co-authored-by: Markus Wolf <markus.wolf@new-work.se> * test: add runner test for job status check functions Co-authored-by: Markus Wolf <markus.wolf@new-work.se> * test: add unit tests for run context if evaluation Co-authored-by: Björn Brauer <zaubernerd@zaubernerd.de> * refactor: move if expression evaluation Move if expression evaluation into own function (step context) to better support unit testing.

Since context values are immutable an added value requires to keep the new context in all cases. This is fragile since it might slip unnoticed to other parts of the code. Storing the error of a job in the context map will make it more stable, since the map is always there and the context of the pipeline is stable for the whole run. * feat: steps should use a default if expression of success() * test: add integration test for if-expressions * chore: disable editorconfig-checker for yaml multiline string Co-authored-by: Björn Brauer <zaubernerd@zaubernerd.de> Co-authored-by: Björn Brauer <bjoern.brauer@new-work.se>

implement pre and post steps (#1089) * feat: add post step to actions and add state command This commit includes requried changes for running post steps for local and remote actions. This allows general cleanup work to be done after executing an action. Communication is allowed between this steps, by using the action state. * feat: collect pre and post steps for composite actions * refactor: move composite action logic into own file * refactor: restructure composite handling * feat: run composite post steps during post step lifecycle * refactor: remove duplicate log output * feat: run all composite post actions in a step Since composite actions could have multiple pre/post steps inside, we need to run all of them in a single top-level pre/post step. This PR includes a test case for this and the correct order of steps to be executed. * refactor: remove unused lines of code * refactor: simplify test expression * fix: use composite job logger * fix: make step output more readable * fix: enforce running all post executor To make sure every post executor/step is executed, it is chained with it's own Finally executor. * fix: do not run post step if no step result is available Having no step result means we do not run any step (neither pre nor main) and we do not need to run post. * fix: setup defaults If no pre-if or post-if is given, it should default to 'always()'. This could be set even if there is no pre or post step. In fact this is required for composite actions and included post steps to run. * fix: output step related if expression * test: update expectation * feat: run pre step from actions (#1110) This PR implements running pre steps for remote actions. This includes remote actions using inside local composite actions. * fix: set correct expr default status checks For post-if conditions the default status check should be always(), while for all other if expression the default status check is success() References: https://docs.github.com/en/actions/learn-github-actions/expressions#status-check-functions https://docs.github.com/en/actions/creating-actions/metadata-syntax-for-github-actions#runspost-if * fix: remove code added during rebase
