--------------------------------------
Summary: Webui pailer stops paging if a line is bigger than 8*4096
bytes.
Key: MESOS-8571
URL: https://issues.apache.org/jira/browse/MESOS-8571
Project: Mesos
Issue Type: Bug
Components: webui
Reporter: Benjamin Mahler
Reported by [[email protected]], there appears to be a bug in the
pailer when the entire chunk that's been paged does not contain a newline.
An example log file contained a line that is 63319 bytes long, and the pailer
chunk size is only 32768 bytes. The pailer tries to truncate everything in
front of the first newline in the chunk, but since there isn't one in this
case, the entire chunk gets truncated:
https://github.com/apache/mesos/blob/1.5.0/src/webui/master/static/js/jquery.pailer.js#L204-L209
Not sure what the fix is here, maybe to keep reading until we see a newline
(seems problematic in the case that there's a huge amount of data with no
newlines), or to just display the whole chunk in this case without any newlines
(not sure if there will be any display bugs here).
