73920 - "null" appears in many NNTP log messages

Status: RESOLVED INVALID

(MailNews Core :: Networking: NNTP, defect)

Description

[Henrik Gemal]

I'm not sure if it's important or not but anyways:
there seems to be a lot of NNTP log comments that contain "null". Like:
0[346138]: m_messageID = (null)
0[346138]: group = (null)
0[346138]: commandSpecificData = (null)
0[346138]: Receiving: (null)

So, re-opening this bug.  Sorry for the mess.

Comment 6

[Håkan Waara]

As I said some 7 months earlier, I don't think this is a bug. :)

We are showing the actual value, which happens to be null in this case. If this 
causes you no harm, it's a feature and no bug.

Marking as worksforme. Gemal, please verify / comment.

Attachment: Outlook Express' logging output for posting and then reading

Stephen: What was the Outlook Express log to show?

The reason why I logged this bug, was just I didn't understand why some log
comments was showing "null". "null" normally means something is detected wrong,
etc..

[Håkan Waara]

Null need not mean that something is wrong, it's just a 'techie' word for
"nothing" or "empty".

Gemal, can you give us a testcase in which 'null' as a value appears?  IE, does
it happen on public servers like news.mozilla.org?  The log from Outlook Express
was just meant to show (since I can't figure out how to log what 4.x does) that
'null' isn't a common value for news (in this simple posting and reading
testcase that I came up with).

Attachment: NNTP log when I open the news.mozilla.org account. Contains null a few places.

Leaving open, until I hear from Seth on the expected behavior.  It may turn out
that Outlook Express doesn't log null values.

Comment 13

[Henrik Gemal]

The "null" value not being present in the OE log, is just because we log
different thing. I just wanna be sure that stuff like:
0[3441b0]: (31e5138) m_messageID = (null)
0[3441b0]: (31e5138) group = (null)
0[3441b0]: (31e5138) commandSpecificData = (null)
doesn't mean that Mozilla is either doing something wrong or detecting some
server response wrong.
We have a lot of NNTP bugs and these null's could perhaps be a cause. Just want
to be 110% sure...

sorry for the spam.  making bugzilla reflect reality as I'm not working on these bugs.  filter on FOOBARCHEESE to remove these in bulk.

A trip though the NNTP parser code reveals that not only are the specified null values not problematic, they are necessary to trigger the newsrc information.

Are there any other null values not generated by ParseURL or LoadURL?

RESO INVALID. This is not a problem.
