Jenkins 2.24, Linux vmkvmx01 2.6.32-431.29.2.el6.x86_64 #1 SMP Sun Jul 27 15:55:46 EDT 2014 x86_64 x86_64 x86_64 GNU/Linux
Description
Notifying Jenkins of a new mercurial commit via /mercurial/notifyCommit responds with a '500 Server Error'. It looks like the notification is accepted in the Jenkins logs but an exception is also raised. The logs also show all the job polling that is triggered, perhaps related to the issue?

jglick hah, I know. It was my attempt to de-identify the logs. They are all unique job names however.
Well, then you just have a huge number of jobs all using the same repository, I guess? So MercurialStatus needs to be patched to cap the number of job names it will enumerate in its header.
jglick Hrm, I wonder if you can generate the "Response header too large" exception while adding properties to the header. It looks like the size isn't checked until the header is flushed just before the body starts being written.
I'm certainly not checking the results in the header but others might. Should it just be a cap with no warning? Or should there be a further header with number of projects triggered? (with a possible "truncated" property as well?)
Should it just be a cap with no warning?
Maybe some kind of notation indicating that the list was truncated, so scripts relying on the header would fail predictably.
Similar code exists in git-plugin but strangely I can find no analogous issue.

added a comment - To remove the strangeness, I just ran into the same problem (500 Server Error,Commit failed,Response header too large) using only git repos. (Jenkins 2.46.3, Git plugin 3.3.0, Git-client plugin 2.4.6)

looks pretty fishy.
