[hobbit] Xymon version 4.2.2 RC1 available

[Graham Nayler]

I'm not running 4.2 code, but looking at the source for areas I have had 
some interest in in 4.3, I think there are a few bugs in this:

hobbitd\rrd\do_ncv.c
------------
1) NCV or SPLITNCV will not recognise signed values.
Line 75: skip past '-' or '+' before strspn call.

2) Potential inconsistent results if SPLITNCV datasource name starts with a 
non-alphanum.
Line113: check for outidx==0 before checking dsname[outidx-1]

3) Memory leak in SPLITNCV.
Line 190: call xfree(params[i]) prior to setting params[i] = NULL.
paridx really ought to be reset to 1 here also. As it stands it is reset on 
the next iteration, but that's really ugly.

4) Lines 198-202 are either unnecessary or dangerous. params[2] is 
uninitialised at start of routine (line30), or when reinitialised (line 
130). This section could possibly attempt to free random values in memory if 
the routine failed to find any valid SPLITNCV lines in input. Unnecessary if 
valid SPLITNCV lines found.

5) This routine will not recognise input lines with &{RED|YELLOW|GREEN} 
prior to the dsname. Maybe this was a 4.3 functional improvement? (4.3 code 
sits between lines 72 and 73 of this file).

hobbitd\client\bbwin.c
-------------------
6) Timediff from BBWIN clients with central configuration.
The BBWIN client 0.12 reports its epoch as whole seconds only, without the 
decimal part. The current code fails if no decimal part is supplied. So in 
hobbitd\client\bbwin.c, function bbwin_clock_report() replace the lines 
186-7
                p = strstr(clockstr, "epoch:");
                if (p && (sscanf(p, "epoch: %ld.%ld", (long int 
*)&clockval.tv_sec, (long int *)&clockval.tv_usec) == 2)) {
by
                int fields;

                p = strstr(clockstr, "epoch:");
                clockval.tv_usec = 0;
                if (!p)
                      ; /* do nothing further */
                else if( (fields = sscanf(p, "epoch: %ld.%ld", (long int 
*)&clockval.tv_sec, (long int *)&clockval.tv_usec)) < 1)
                     dbgprintf("Failed to parse time from '%s'\n", p);
                else {

This will now accommodate either decimal or integer timestamps

> This is how I would expect the interim 4.2.2 release to be.
> It includes the following changes from 4.2.0:
>
> *) Due to the Hobbit project being renamed to Xymon (for
>   legal reasons), the documentation has been updated to
>   refer to this as the name of the project.
> *) All patches from the "all-in-one" patch have been applied
> *) Patches from Debian and Mandriva source archives and
>   elsewhere have been merged, fixing:
>   - The "Critical Systems" configuration report would crash
>     when hosts were in NKview.cfg, but no NK tags were in
>     bb-hosts (from Mandriva)
>   - SSL certificates with 4-digit expiration years would
>     crash the network tester (from Debian)
>   - Newer OpenLDAP versions have a different API, so
>     the LDAP test code would not build correctly (from
>     Debian)
>   - Old Big Brother clients report disk output with no
>     header line (from Debian)
>   - The bb-hosts syntax for HTTP testing via a proxy
>     could not support https target-URL's (from Debian)
>   - Certain SuSE versions would not be identified by
>     the Linux client as such (only affected OS name
>     displayed in the "info" status).
> *) Support for sending custom graph data in a "trends"
>   data message (from
>   http://www.hswn.dk/hobbiton/2007/01/msg00236.html)
> *) Split-NCV and TRACKMAX support for custom graphs (from
>   http://www.hobbitmon.com/hobbiton/2007/03/msg00368.htm).
> *) Support for the "BBWin" client http://bbwin.sf.net/
>   in centralized (server-side) configuration mode.
>   Based on BBWin v. 0.12.
> *) Support for the "hobbit-perl-client" add-on
>   http://hobbit-perl-client.sf.net/ .
>   Based on perl-http-client v1.15
> *) Support for the "Devmon" SNMP data collector
>   http://devmon.sf.net/ based on Devmon 0.3.0.
>
> A last-minute update for Devmon was missed in the RC1
> source file, so Devmon users should grab the latest
> hobbitd/rrd/do_devmon.c source from
> http://hobbitmon.svn.sourceforge.net/viewvc/hobbitmon/branches/4.2.2/hobbitd/rrd/do_devmon.c?revision=6002
> and copy to hobbitd/rrd/do_devmon.c . This will be included
> in the final 4.2.2 release.
>
> Please test this if you can, and report problems to the
> mailing list. Since all of this code has been in use for
> quite some time, I would not expect a lot of problems.
> So the target date for the 4.2.2 release is Dec. 10.
