Re: Build description longer than 30 chars has hex zero width space added

Tom FENNELLY do you have any thoughts on this? In Chrome this feature does not actually cause the text to wrap, so we get zero width spaces in the string and nothing else in return, it seems.

Re: Build description longer than 30 chars has hex zero width space added

I take it back - if the build description is just a steady string of alpha characters, it seems to wrap as intended. But when we set the description to the version string that we generate internally (our use case for this), it doesn't wrap at 30 chars. Maybe this is because we always have . and + in the string, among other non-alphanum characters.

Re: Build description longer than 30 chars has hex zero width space added

We've faced this issue on Jenkins 2.8.4 with the GitHub PR Builder plugin where we add the PR's URL to the description. People copy and paste it into their browser's window and, instead of going to the page, Chrome/Firefox won't consider it a URL and instead search for that value.

Re: Build description longer than 30 chars has hex zero width space added

We were able to work around this issue by adding the following to our custom theme JS: insertZeroWidthSpacesInElementText=function(){}

Build description longer than 30 chars has hex zero width space added

Problem still exists in Jenkins 2, e.g. 2.124. We see it not at fixed widths, but at every space of the description string. _See below output, where the actual contents are shown with either xxd or od. In xxd you see extra bytes 'e2 80 8b' and in od you see 'b nul vt' (342 200 213). echo "(BR: ​5c12ee9f, ​SW: ​28d0325c, ​BLD: ​60.776) " |xxd 00000000: 2842 523a 20e2 808b 3563 3132 6565 3966 (BR: ...5c12ee9f 00000010: 2c20 e280 8b53 573a 20e2 808b 3238 6430 , ...SW: ...28d0 00000020: 3332 3563 2c20 e280 8b42 4c44 3a20 e280 325c, ...BLD: .. 00000030: 8b36 302e 3737 3629 200a .60.776) . echo "(BR: ​5c12ee9f, ​SW: ​28d0325c, ​BLD: ​60.776) " |od -ac 0000000 ( B R : sp b nul vt 5 c 1 2 e e 9 f ( B R : 342 200 213 5 c 1 2 e e 9 f 0000020 , sp b nul vt S W : sp b nul vt 2 8 d 0 , 342 200 213 S W : 342 200 213 2 8 d 0 0000040 3 2 5 c , sp b nul vt B L D : sp b nul 3 2 5 c , 342 200 213 B L D : 342 200 0000060 vt 6 0 . 7 7 6 ) sp nl 213 6 0 . 7 7 6 ) \n 0000072 Change By: Thomas De Schampheleire Environment: Jenkins 1.596.1 , 2.124

Re: Build description longer than 30 chars has hex zero width space added Workaround suggested by Luke Street indeed works. The JavaScript function insertZeroWidthSpacesInElementText is defined and called from war/src/main/webapp/scripts/hudson-behavior.js and indicates that this is actually a feature. It was introduced by Tom FENNELLY in commit cb9036c4552 and refined in b31bb1cc1c5. Tom FENNELLY, could you give input on this issue, please?

Re: Build description longer than 30 chars has hex zero width space added

I asked in https://github.com/jenkinsci/jenkins/pull/3377 that the author investigates whether a similar approach could be done for this. No response. Perhaps one of the watchers here feels up to the task?

Re: Build description longer than 30 chars has hex zero width space added

We had just encountered same problem once we started using Build Name Setter Plugin. Can confirm that workaround provided by Luke Street does the job - makes build names copy-pasteable. As far as I can see this is only reproducible in Build History panel. Everywhere else names of builds were displayed without ​ in HTML.

Re: Build description longer than 30 chars has hex zero width space added

Hi, thank you for the suggested workarounds. Pardon my inexperience, do I need to have a custom theme to put Luke Street's JS line? It won't work with stock theme? Also waiting for the complete solution, it stole a lot of hours to find the invisible character.

Also waiting for the complete solution, it stole a lot of hours to find the invisible character. Btw, for description the character appears after 30 char and for name (the bold text) its after 20.
