Hello,

0.7 is missing major functionality present in the 0.6.8, namely TTY support.
https://groups.google.com/forum/#!topic/cgdb-dev/m_FMkda4Ua8

If exporting TERM=dumb is all that is needed, I prefer patching 0.6.8 over using 0.7.

Hm, I now see that it wasn't the case of sleeping Fedora maintainer but
a deliberate choice.  Thanks for explanation, and my sympathies for the
current state that doesn't accommodate some use cases it used to.

The best compromise I could come up with to handle this, free of any
patching (which I perceive as a last resort):

cat /etc/gdbinit.d/cgdb.gdb
> shell readlink /proc/$$/fd/* | grep -q cgdb_log && printf '%s\n%s\n' "set style enabled off" "shell truncate -s0 ~/.cgdb/gdbinit" > ~/.cgdb/gdbinit || truncate -s0 ~/.cgdb/gdbinit
> source ~/.cgdb/gdbinit

Provided that it works (haven't actually downgraded back, but behaved
as expected with 0.7.0) without any interferences (at worst, colours
will be disabled with a regular gdb sessions if one happens to debug
something with "cgdb_log" in the name or so), could such a file be
shipped with currently packaged version of cgdb, then?

Sadly, while the above workaround is nicely self-contained and worked,
I cannot recommend it unconditionally -- there's a sife effect of
the portion of other (Fedora/EL-specific) "post-processing hook" being
dropped:

- under gdb:

> Program terminated with signal SIGSEGV, Segmentation fault.
> #0  0x00000000004c8bb3 in strcoll ()
> Missing separate debuginfos, use: dnf debuginfo-install busybox-1.28.3-3.fc30.x86_64
> (gdb) 

- under cgdb:

> Program terminated with signal SIGSEGV, Segmentation fault.
> #0
> (gdb) 

That may be a bug of gdb on it's own that it's prone to forget about
commands to execute, and for me, it's less intrusive that having to
disable "style" each time around, but thought I'd share this finding.

To make it more interesting, I stand corrected per more observations,
it happens only under rather rare circumstances, so perhaps it's still
a viable solution for now?

Now that I've finally switched to F30, I'm seeing the same.
AFAIK, adding 'set style enabled off' to ~/.gdbinit solves the problem.
I'll see if I can somehow change the cgdb code to inject this line.

Note that while that'd be a solution of the first choice, it's not
so great for people flipping between both cgdb and plain gdb.

That's what I tried address with the proposed solution in [comment 2].

Hmm, actually two corrections, replace s/cgdb_log/tgdb_log/ in the gdb
script from [comment 2] (accidentally, I tested that with cgdb 0.7.0,
but it works also with older, currently packaged version when such change
is made).

And the other is that my observations regarding missing
"[...] use: dnf debuginfo-install [...]" messages were also only
relevant to 0.7.0, it's just fine with cgdb-0.6.8-12.fc31.x86_64.

All in all, unless cgdb is updated 0.7.0, all should be fine with the
proposed /etc/gdbinit.d/cgdb.gdb script (after the correction per above).

Hello,

Sorry for the long AFK. I finally managed to free some time to work on it.

I must admit solution #2 doesn't make me feel comfortable, as it changes/overwrites the user's gdbinit.
I've began looking at the code, and it seems that I can 'set style enabled off' without it.

I'll keep you posted.
