 02 Nov 2004, Renee Poutissou, Info, Event Builder info in mhttpd Status page
|
Information about the Event Builder statistics has been removed from the
Status page in mhttpd. I heard from Pierre that this information might
be redundant when using the new Event Builder format???

We sporadically (like once per few hours) have an error message when we access the
history plots through mhttpd:

I confirm I see same on the agmini system. Two problems: (a) error message is wrong, it's a
short read, not a read error (clue: read() syscall does not return "no such file"). (b)
mlogger is supposed to write history in record-size blocks, read in the same record size
|
|
16 Aug 2023, Stefan Ritt, Bug Report, Error accessing history files

Tonight we got another error of that type after the update:
04:17 - [mhttpd,ERROR] [history_schema.cxx:2913:FileHistory::read_data,ERROR] Cannot read
|
|
17 Aug 2023, Konstantin Olchanski, Bug Report, Error accessing history files
|
Confirmed. The error message is wrong. It is printed after a short read(), but short read() does not
set errno, and errno reported by the error message is from some previous syscall. Corrected error
message is already committed. K.O.
