From: Ludovic Courtès <ludo <at> gnu.org> To: guix-patches <at> gnu.org Cc: Ludovic Courtès <ludo <at> gnu.org> Subject: [PATCH 0/8] Add 'with-build-handler' and use it to improve UI feedback Date: Thu, 19 Mar 2020 11:56:42 +0100
Hello Guix!
This patch series is to always display upfront what’s going to
happen, even in the presence of “dynamic dependencies” (grafts),
as was reported at:
https://issues.guix.gnu.org/issue/28310
With this patch, any time ‘build-things’ is called, we have an
opportunity to display what’s going to happen and to choose
whether or not to actually build things (dry runs).
I’m wondering whether/how this mechanism could be extended to
address:
https://issues.guix.gnu.org/issue/22990
We’ll see!
Ludo’.
Ludovic Courtès (8):
syscalls: 'with-file-lock' re-grabs lock when reentering its dynamic
extent.
store: Add 'with-build-handler'.
ui: Add a notification build handler.
guix build: Use 'with-build-handler'.
deploy: Use 'with-build-handler'.
pack: Use 'with-build-handler'.
guix package, pull: Use 'with-build-handler'.
guix system: Use 'with-build-handler'.

* guix/build/syscalls.scm (call-with-file-lock)
(call-with-file-lock/no-wait): Initialize PORT in the 'dynamic-wind'
"in" handler. This allows us to re-enter a captured continuation and
have the lock grabbed anew.

From: Ludovic Courtès <ludo <at> gnu.org> To: 40130 <at> debbugs.gnu.org Cc: Ludovic Courtès <ludo <at> gnu.org> Subject: [PATCH 6/8] pack: Use 'with-build-handler'. Date: Thu, 19 Mar 2020 12:02:50 +0100
* guix/scripts/pack.scm (guix-pack): Wrap 'parameterize' in
'with-build-handler'. Remove explicit call to 'show-what-to-build'.
Call 'build-derivations' regardless of whether OPTS contains 'dry-run?'.
