Subject: Re: [RFA] Show locno for 'multi location' breakpoint hit msg+conv var $bkptno $locno.
Date: Fri, 29 Apr 2022 18:26:38 +0200	[thread overview]
Message-ID: <874988bef430ed6e239e74a4a94eb2ad13175f4a.camel@skynet.be> (raw)
In-Reply-To: <20220417155311.3487509-1-philippe.waroquiers@skynet.be>

Ping ?
(doc was reviewed by Eli already, I will handle his comments in V2).

In the meantime, I did a small "opinion poll" at my work about the display
of breakpoint nr and location nr in the breakpoint hit message.

Below is the detailed feedback, summary is that everybody prefers
to see the breakpoint and location number, and does not see a (real)
need to have this configurable.

Thanks
Philippe
 

GDB should always display 1.6:
------------------------------
* because this is consistent with the output of info breakpoint
  and obeys the Principle of Least Astonishment

* Same.

* Sounds good. Does not see why this should be user configurable
  but does not object to have an option (with default on).

* always show information.

* always show information.

GDB should have a config option to display 1.6, default on:
-----------------------------------------------------------
* consistent with 'info breakpoint', immediately informs the user about
  something in a way which is not confusing.
  Option to control it might be useful if someone parses the 'breakpoint hit' messages
  (but which is not something that should be done)

GDB should have a config option to display 1.6, default off:
------------------------------------------------------------
