Subject: [bug#50238] [PATCH v2] build-self: Try printing nicer error messages
Date: Tue, 22 Mar 2022 23:24:02 +0100 [thread overview]
Message-ID: <ef71cec4d9915f8a1b1dff6d08af7c444fc20caa.camel@telenet.be> (raw)

[-- Attachment #1.1: Type: text/plain, Size: 193 bytes --]
The revised patch allows time travelling from v1.1.0 to
(master + patch), by not always setting #:unwind?. Next step: test
some older versions (v1.0.0, v0.2?, ...?)?
Greetings,
Maxime.

Subject: [PATCH] build-self: Try printing nicer error messages.
This prevents daunting backtraces like in
<https://issues.guix.gnu.org/50232> by only printing
the relevant information: that 'subversion' fails to
build.
* build-aux/self.scm (build-program): Wrap the 'run-with-store'
in a 'with-error-handling'.
* guix/ui.scm (guard*): Don't explode on old Guiles.
