[GRASS-dev] Re: [GRASS-user] g.gisenv DEBUG broken!

Sorry, a wrong example, trying again -- GRASS *gisenv* variable DEBUG:

g.gisenv set=DEBUG=5
g.gisenv get=DEBUG
5

g.remove x
Remove <x>
WARNING: <x> nothing removed

.... no debug message, should be(?)

grep G_debug general/manage/lib/do_remove.c
G_debug (1, "%s: %s", list[n].desc[i],_("missing"));
G_debug (1, "%s: %s", list[n].desc[i],_("removed"));
G_debug (1, "%s: %s", colr2, _("missing"));
G_debug (1, "%s: %s", colr2, _("removed"));

odd, same here.

g.gisenv set="DEBUG=5"
echo "1|1" | v.in.ascii out=foo

no debug messages!

It seems that lstr = G__getenv( "DEBUG" ); in lib/gis/debug.c
fails for some reason (lstr gets set to NULL).

???

we discussed this with soeren (huhabla) on irc while ago with the
result, that if the module is runing in gdb environment, debuging works

i do not know why, but it was so :-/

works

i do not know why, but it was so :-/

it works for this:
g.mremove foo*

and this:
v.db.addtable rand_pts

but not for this:
echo "1|1" | v.in.ascii out=foo

Hi all,

is there anybody who has *no* problem with g.gisenv variable DEBUG?? I
have, I was trying to find out why... I have found a strange problem
in function

G_getl2 ()

[...snip...]

    buf[i] = '\0';

    G_debug ( 4, "G_getl2: ->%s<-", buf ); <-----------
    // G_debug helps
    return ret;
}

After reading the first line in read_env() [env.c], the function
G_debug () is called, it cause that (see debug.c) grass_debug_level
variable is set to 0. As a result no debug message will be displayed
regardless to DEBUG value.

I don't know why, just trying to find out why no debug messages are
not displayed any more...

Best, Martin
