Subject: 26.0.50; Unsafe recovery should be off by default in batch mode
Date: Thu, 18 May 2017 21:44:22 +0200

In batch mode there will usually be no long-lived buffers with
non-recoverable contents, therefore the reasoning for
`attempt-stack-overflow-recovery' and
`attempt-orderly-shutdown-on-fatal-signal' being t doesn't apply.  This
means that these variables should be nil by default in batch mode.

I see your point, but what are the arguments for changing their values
in batch mode?  IOW, what advantages will this give us?

When debugging Emacs internals or running unit tests, setting these
variables to nil will cause obvious and clear failures instead of silent
recovery attempts.

OK, but the batch mode is not used only for debugging or testing.
Perhaps we should change the values in these two cases.

That would be a good start. However, I still think these should be off in
batch mode by default; batch mode is very unlikely to be used for
circumstances where they could be useful.

Batch mode is frequently used to test or present problems that happen
in interactive sessions, so I'd like to avoid making the batch mode
too different from the rest.

I understand Eli's message here as wontfix.  I'm closing this bug report
as such.

If anyone disagrees, feel free to reopen.
