[PATCH v4 00/31] error: auto propagated local_err |

Hi all!
Here is a proposal of auto propagation for local_err, to not call
error_propagate on every exit point, when we deal with local_err.
There are also two issues with errp:
1. error_fatal & error_append_hint/error_prepend: user can't see this
additional info, because exit() happens in error_setg earlier than info
is added. [Reported by Greg Kurz]
2. error_abort & error_propagate: when we wrap
error_abort by local_err+error_propagate, resulting coredump will
refer to error_propagate and not to the place where error happened.
(the macro itself don't fix the issue, but it allows to [3.] drop all
local_err+error_propagate pattern, which will definitely fix the issue)
[Reported by Kevin Wolf]
Still, applying new macro to all errp-functions is a huge task, which is
impossible to solve in one series.
So, here is a minimum: solve only [1.], by adding new macro to all
errp-functions which wants to call error_append_hint.
v4;
02: - check errp to be not NULL
- drop Eric's r-b
03: add Eric's r-b
04: - rename macro to ERRP_AUTO_PROPAGATE [Kevin]
- improve comment and commit msg, mention
error_prepend
05: - handle error_prepend too
- use new macro name
- drop empty line at the end
commit message for auto-generated commits updated,
commits regenerated.
I'll use cc-cmd to cc appropriate recipients per patch, still
cover-letter together with 04-06 patches should be interesting for
all:
