[JENKINS-44972] Truncated log displayed in middle of line, showing Base64-encoded ConsoleNote garbage · jenkinsci/jenkins#22143

When you view a truncated log file ( Skipping ... Full Log ) often the text will resume in the middle of a line. This is ugly enough but when the offset happens to be in the middle of an encoded ConsoleNote you get a confusing batch of Base64 garbage before the stream corrects itself. Either console.jelly should employ a more sophisticated core API to find an offset which is at a line boundary (which might be inefficient); or AnnotatedLargeText.writeHtmlTo should skip any initial partial line, for example by using start - 1 and using a wrapper OutputStream which discards everything prior to the first newline character and thereafter mirrors its input; or ConsoleAnnotationOutputStream should have an option to do that. --- Originally reported by jglick , imported from: Truncated log displayed in middle of line, showing Base64-encoded ConsoleNote garbage assignee : shreygupta198 status : Open priority : Minor component(s) : core label(s) : newbie-friendly resolution : Unresolved votes : 2 watchers : 4 imported : 2025-11-24 Raw content of original issue When you view a truncated log file ( Skipping ...

研究方向: The issue involves the truncated log display in Jenkins. Possible fixes include modifying console.jelly to use a line boundary offset, or modifying AnnotatedLargeText.writeHtmlTo to skip partial line, or adding an option in ConsoleAnnotationOutputStream. Start by examining the source files in the Jenkins core, particularly the 'core/src/main/java/hudson/console/' package. Review the existing comments in the issue and consider implementing one of the proposed solutions, ensuring it does not break existing tests.
