feat(#4342) logfile view - chunk navigation

[vetri15]

Implemented logfile chunk navigation and recovery improvements.

• Added previous/next chunk navigation
• Show skipped and remaining byte counts
• Render only complete log lines across chunk boundaries
• Automatically reset and resume follow mode after logfile compression
• Improved tail-follow scroll behavior and manual chunk navigation

Hi @cdprete,

I created a new PR for issue #4342, as I realized my previous approach would not be sufficient to implement this feature cleanly.

I think the previous PR(#5326) can be closed. Could you please review the new PR and let me know if any further changes are needed?

It took longer than I initially expected because of the edge cases involved.

Hi @vetri15.

You can close the old PR yourself if you think the new one supersedes it.

Could you please review the new PR and let me know if any further changes are needed?

I try to do it asap.

No worries.

@SteKoe @erikpetzold @ulischulte @hzpz can you maybe allow the pipeline to run in the meantime so that we make sure there are no potential issues? Tnx

[vetri15]

Yeah, you were right @cdprete.

I have closed the old PR.

By the way, please be aware that there are issues with empty lines.
I don't know if your PR already covers it somehow, but for details have a look at #5388.

Hi @cdprete,

Thanks for pointing this out. I checked #5388 and updated this PR to handle empty log lines in the logfile view as well.

Empty strings are now rendered as <br> instead of an empty <pre>, so blank lines from the log file are preserved visually. I also brought over the related logfile styling from #5388 for tr, td, br, pre, and logfile links.

Hi @vetri15.

I just wanted to inform you I updated the styles in my PR as follows:

• removed w-full from pre and br since on tr and td is already enough
• changed the on-hover target from pre to td to respect also the empty new lines
