Instead of relying onThe Timestamper plugin currently inserts a console notes, store note into every line of the timestamps in a more compact and human-readable format build's log file.
The [consoleConsole notes|http://javadoc.jenkins-ci.org/byShortName/ConsoleNote] are a feature supported by Jenkins. They allow the timestamps to be formatted at the time the console is viewed, rather than the time that the build was running. Any alternative solution also needs to support formatting at view time.
Inserting a console note into every line, as the Timestamper plugin does, has several disadvantages: - They increase the file size of the log. - They make the log file more difficult to read in a text editor. - External scripts may need to skip over the console notes when reading the log file. (Jenkins itself and the Jenkins plugins already need to deal with console notes, so they are not as much of a concern.) - They make it difficult to read the times with a script, e.g. to determine which parts of the build are the slowest.
It would be nice to store the timestamps as in a separate file to the number of elapsed milliseconds since the build started console, and in a more efficient format. The Timestamper plugin would still need a way to replace insert these timestamps when Jenkins displays back into the console log. This may require changes to when it is being viewed in Jenkins core.
Backwards compatibility: * The Timestamper plugin should to retain the ability to display existing console notes. * There should be an option to still use console notes, because a few people have written scripts to read them from the log file. * The /timestamps URL (introduced in version 1.3.2) must continue to read the console notes when this option has been selected.
