Stream HTML console log #11177

das7pad · 2025-10-07T22:46:39Z

Part of Viewing large logs runs out of memory pipeline-graph-view-plugin#704
Based on Add new LargeText interface based constructor for AnnotatedLargeText #11071
Uses incremental from Add new streaming mode for LargeText stapler#722

The initial purpose of this PR is obtaining an incremental version of Jenkins core for using in the workflow-api plugin.

Chain: stapler -> Jenkins core -> workflow-api -> pipeline-graph-view-plugin.

Once #11175 has landed, I can land #11071 and remove the commits from this PR.

Testing done

See updated tests for the log/progressiveHtml endpoint. Open console while build is in progress.

Submitter checklist

The Jira issue, if it exists, is well-described.
The changelog entries and upgrade guidelines are appropriate for the audience affected by the change (users or developers, depending on the change) and are in the imperative mood (see examples). Fill in the Proposed upgrade guidelines section only if there are breaking changes or changes that may require extra steps from users during upgrade.
There is automated testing or an explanation as to why this change has no tests.
New public classes, fields, and methods are annotated with @Restricted or have @since TODO Javadocs, as appropriate.
New deprecations are annotated with @Deprecated(since = "TODO") or @Deprecated(forRemoval = true, since = "TODO"), if applicable.
New or substantially changed JavaScript is not defined inline and does not call eval to ease future introduction of Content Security Policy (CSP) directives (see documentation).
For dependency updates, there are links to external changelogs and, if possible, full differentials.
For new APIs and extension points, there is a link to at least one consumer.

Desired reviewers

Before the changes are marked as ready-for-merge:

Maintainer checklist

There are at least two (2) approvals for the pull request and no outstanding requests for change.
Conversations in the pull request are over, or it is explicit that a reviewer is not blocking the change.
Changelog entries in the pull request title and/or Proposed changelog entries are accurate, human-readable, and in the imperative mood.
Proper changelog labels are set so that the changelog can be generated automatically.
If the change needs additional upgrade steps from users, the upgrade-guide-needed label is set and there is a Proposed upgrade guidelines section in the pull request title (see example).
If it would make sense to backport the change to LTS, a Jira issue must exist, be a Bug or Improvement, and be labeled as lts-candidate to be considered (see query).

This will avoid high churn of buffers when resetting the line buffer at the end of each line and processing long log lines.

Increase buffer sizes in ConsoleAnnotationOutputStream to avoid high churn of buffers when resetting at each end of a line.

This seems like a potentially incompatible change. Is there a need for it?
