Description

Original:   Using Jenkins REST API to fetch the job console log. While adding the "start" parameter to fetch log based on the offset, Sometimes, a extra long random string, at least to me, will be added at the beginning of the log content. WHat is this string and how can I separate and remove it from the content? The example is as below where the part "ha:////4G0y24vTRyi8PVe..." is not part of the actual log:   {code:java} http://localhost:18181/job/my_job1/333/logText/progressiveText?start=8831 [Pipeline] { [Pipeline] } $ docker stop --time=1 e27f2d5b083decc0ec35355e513c2eb93670fcfcbc1f76740c1a5a075d676478 $ docker rm -f e27f2d5b083decc0ec35355e513c2eb93670fcfcbc1f76740c1a5a075d676478 [Pipeline] // withDockerContainer [Pipeline] } [Pipeline] // node Stage "Terraform Destroy" skipped due to when conditional [Pipeline] } http://localhost:18181/job/my_job1/333/logText/progressiveText?start=8832 [8mha:////4G0y24vTRyi8PVeV4GnNqRr5FVABXpzobjFozxtf+i5VAAAApx+LCAAAAAAAAP9tjTEOwjAUQ3+LOrAycohUQjAhpq5RFk4QmhDSRv+Xn5R24kRcjTvQUokJD5ZtyXqvNxSR4UTsRGOx9RhrL7rQuymJgbi9BhpEQxdRE0YKVig7KDK2WqqiZGFRlsNKwtpiHSh6dAk2stEPXQaNrjwnnrajhNybOzwhkxM5aU7fMjJsb72JhD/OXwCMXYJ8t5/tMD+LD/hYjrHCAAAA[0m**[Pipeline] { [Pipeline] } $ docker stop --time=1 e27f2d5b083decc0ec35355e513c2eb93670fcfcbc1f76740c1a5a075d676478 $ docker rm -f e27f2d5b083decc0ec35355e513c2eb93670fcfcbc1f76740c1a5a075d676478 [Pipeline] // withDockerContainer [Pipeline] } [Pipeline] // node Stage "Terraform Destroy" skipped due to when conditional [Pipeline] } {code}   According to [Teminal Escape Code|https://en.wikipedia.org/wiki/ANSI_escape_code], "ESC [8m", which is the beginning of the unexpected string, will hide the later output and "ESC [0m", which is the end of unexpected string, will reset the previous setting. I parsed the output with "xxd" and didn't find the "ESC" before "[8m". Is it possbile that Jenkins forgets to send the "ESC"? And what does "ha:////" stands for?
