Surface n most recent commits in Bitrise job

Question & Answer
,
1

Is there a way to expose more than just the most recent commit when a bitrise job executes? For example, I’d like to expose all of the commits since the last job was run, rather than just the commit that triggered the job.

What do you mean by last? On the same branch or globally? Only finished builds or running ones too?

3

On the same branch. So if I make five commits locally, push to remote, then a build is triggered, am I able to see all 5 recent commits? Or is there a way that I can just always see the last n number of commits on a branch?

In general, with git:

git log  --pretty=oneline | head -n 5

or:

git log -5

You can get this in a Script step, and expose it as an env var with any key you like, e.g.:

#!/bin/bash
set -ex

# get the info
last_five_oneliner="$(git log -5 --pretty=oneline)"

# share it as an env var
envman add --key MY_ENV_KEY --value "$last_five_oneliner"

The output of git log -5 --pretty=oneliner looks like this:

$ git log -5 --pretty=oneline

A quick example bitrise.yml which runs this as a Script step, and then prints the value in another one:

format_version: 2
default_step_lib_source: https://github.com/bitrise-io/bitrise-steplib.git
trigger_map:
- push_branch: '*'
  workflow: primary
- pull_request_source_branch: '*'
  workflow: primary
workflows:
  primary:
    steps:
    - script@1.1.3:
        title: Read & Expose git info
        inputs:
        - content: |-
            #!/bin/bash
            set -ex

            # get the info
            last_five_oneliner="$(git log -5 --pretty=oneline)"

            # share it as an env var
            envman add --key MY_ENV_KEY --value "$last_five_oneliner"
    - script@1.1.3:
        title: Print exposed value
        inputs:
        - content: |-
            #!/bin/bash
            set -e

            echo "MY_ENV_KEY: $MY_ENV_KEY"

If you have any questions just let me know!

Hi @viktorbenei,

Is there a way to find out how many commits I sent with the last push?

7

I don’t think so @dorukkangal , git AFAIK doesn’t record when a commit was pushed, only when it was created.

What’s the use case, what do you want to do with this info?

8

Actually, I want to use this info to create release notes.

changelog_from_git_commits(
    between: [ENV['CI_COMMIT_BEFORE_SHA'], ENV['CI_COMMIT_SHA']],
    pretty: '- %s',
    merge_commit_filtering: 'exclude_merges'
)

We are currently using Gitlab Ci and trying to migrate to Bitrise and it is predefined in Gitlab.

@viktorbenei I guess Circle Ci also supports this feature.
