Hello,
First, kudos! rrdtool 1.2 rocks.
Is it possible to make MAX_VNAME_LEN larger, perhaps FILENAME_MAX?
It's very easy to overflow the default MAX_VNAME_LEN of 29 when you're
constructing vnames in an automated fashion (e.g.
DEF:${MACHINE}_${RRDNAME}).
The following (or similar) should do the job:
$ diff rrd_graph.h.orig rrd_graph.h
8,9c8,9
< #define MAX_VNAME_LEN 29
< #define DEF_NAM_FMT "%29[-_A-Za-z0-9]"
---
> #define MAX_VNAME_LEN 64
> #define DEF_NAM_FMT "%64[-_A-Za-z0-9]"
Thanks!
