GitHub Actions concurrency default workflow runs concurrent by default at most one running and one pending documentation

💡 Result:

By default, when you define a concurrency group in GitHub Actions, the system ensures that at most one job or workflow run is running at any time [1][2]. If another job or workflow within the same concurrency group is already in progress, any subsequent queued job or workflow will be placed in a pending state [1][2]. Regarding the default behavior for pending runs, GitHub Actions is configured to maintain at most one pending job or workflow run in the group [1][2]. If a new job or workflow is queued while another is already pending, the existing pending job or workflow is canceled, and the new one replaces it [1][2]. This behavior is explicitly referred to in documentation as "single" (the default mode) [1][2]. If you wish to allow more runs to queue instead of being automatically canceled, you can change this behavior by setting the concurrency configuration to "max," which allows up to 100 jobs or workflow runs to wait in the queue [1][2].

site:docs.github.com GitHub Actions without concurrency multiple workflow runs default concurrent

💡 Result:

By default, GitHub Actions allows multiple workflow runs and jobs to execute concurrently [1][2]. There is no default limit that restricts a workflow to a single concurrent run; rather, instances of the same workflow can run simultaneously across a repository [1][3]. To change this behavior and restrict concurrency, you must use the concurrency keyword within your workflow file [4][5]. When you define a concurrency group, the default behavior is that only one run can be active (running or pending) at a time [4][3]. If a new run is triggered while another is in progress, the older pending run is automatically canceled by default [4][6]. If you wish to allow multiple runs to queue sequentially instead of canceling previous ones, you can configure the concurrency group to use queuing, which allows up to 100 workflow runs or jobs to wait in line [4][7]. This is achieved by setting the concurrency configuration to use queue: max [4][3]. In summary, GitHub Actions is concurrent by default, and the concurrency keyword is the mechanism provided to opt into sequential execution or controlled queuing [1][6].

Define the notification burst policy before enabling the gate.

When PUSH_EMAIL_ENABLED is true, branches: ['**'] starts the notify job for each branch push. Without a concurrency group, several SMTP jobs can run concurrently. timeout-minutes: 5 limits job duration, not concurrency.

If every push must generate an email, use bounded queueing or SMTP rate limiting. If newer pushes can replace older notifications, add a global concurrency group with cancel-in-progress: true.

In @.github/workflows/push-email-notify.yml around lines 15 - 16, Define the
push notification burst policy before enabling the PUSH_EMAIL_ENABLED gate: add
bounded queueing or SMTP rate limiting if every branch push must send an email;
otherwise configure a global concurrency group for the notify job with
cancel-in-progress enabled so newer pushes replace older notifications. Keep the
existing branches filter unchanged.

GitHub hyperpolymath/smtp-notify-action v0.1.0 commit

💡 Result:

There is no public GitHub repository named hyperpolymath/smtp-notify-action. The user hyperpolymath frequently uses the third-party GitHub Action dawidd6/action-send-mail to implement push-email notifications within their repositories [1][2]. It appears the user may be conflating this specific workflow implementation with a standalone action [1][3][4]. The push-email notification functionality in repositories owned by hyperpolymath is typically managed via a reusable workflow file (e.g.,.github/workflows/push-email-notify.yml) which utilizes dawidd6/action-send-mail [1][2]. No evidence of an action repository named smtp-notify-action exists under the hyperpolymath organization.
