Description: Using Asterisk 1.0.3 stable, performing a sip show peers about 2-3 seconds after another sip show peers will sometimes truncate the first character on the listing. In addtional information, I've shown a copy/paste of the incorrect output. Not too critical, but just annoying :)

It's really hard to see the problem when you can't tell what the full peer name was supposed to be in the first place.

050340005/3050 (Unspecified) D N 255.255.255.255 0 UNKNOWN

is the problem line

it should be

3050340005/3050 ... ... ..

it happens randomly, to different peer names
By: Mark Spencer (markster) 2005-01-18 10:38:51.000-0600

Only on asterisk -r?
By: () 2005-01-18 10:44:12.000-0600

When manager logged in and asterisk -r
By: Mark Spencer (markster) 2005-01-18 16:05:55.000-0600

But not on the main console right?
By: Kevin P. Fleming (kpfleming) 2005-01-18 19:36:17.000-0600

My business partner has reported this problem as well, on CVS HEAD, using "asterisk -r", but I have never seen it myself.
By: () 2005-01-18 22:48:34.000-0600

I apologize, but I don't know what you mean by main console. I log into asterisk via CLI using asterisk -r. Then if I do a sip show peers, then it causes the irregularity. I have tried it on three different terminals, including actually putting a KVM cable on the * machine and checking it from there, SSH for Windows, PuTTY, and Eterm. Same problem. This occurs when also doing a sip show peers from the manager interface.

start asterisk with "asterisk -gcv"

then at that -c console try it again.

Does the problem not occur on CVS head?
By: () 2005-01-19 08:20:47.000-0600

With asterisk -gcv then doing sip show peers, exhibits same behavior... very odd
By: Kevin P. Fleming (kpfleming) 2005-01-19 08:49:01.000-0600

Looking at the CVS HEAD code, I can only see a couple of possibilities where this could be happening... It could be a printf bug, where we are using "-25.25s" to format the name string. I would try to changing that to just "25s" to see if you can still reproduce the problem (although the output format could change slightly).

There is also a small possibility the ast_careful write might have a problem, but that's very unlikely.

(I also noticed that the function for "sip show peers" is building the entire output string into a "srch" buffer then never using it... this could be removed).

Ok, I'm running HEAD on another server. I'll try to reproduce the error on that machine later.
By: () 2005-01-20 07:19:42.000-0600

Ok, problem occurs on HEAD also. Also, it appears that the truncation is totally random, but usually only occurring near the last 10 or so peer listings.

Working on patch... standby

Ok, after looking at 1.0.3 code it seems that it has already been changed to 25s instead of -25.25s. So I don't know what the problem is ??????
By: Mark Spencer (markster) 2005-01-20 21:55:33.000-0600

I seem entirely unable to duplicate this problem even with about 50 peers in my list...
By: () 2005-01-21 06:14:05.000-0600

I have about 150 on my list

Which operating system/distro are you running?
By: Olle Johansson (oej) 2005-02-14 01:40:13.000-0600

No communication for more than two weeks, seems like we can't replicate the bug or that we have lost interest in it. Reopen if you have new information.
