From 376ba0ce570993cf6cdbed19596a245826308382 Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Sat, 4 Apr 2020 23:58:05 +0200 Subject: store: 'with-store' uses 'with-exception-handler'. This ensures the stack is not unwound before the exception is re-thrown, as was the case since 8ed597f4a261fe188de82cd1f5daed83dba948eb, leading to '&store-protocol-error' being uncaught by 'with-error-handling' in (guix scripts build) & co. * guix/store.scm (call-with-store): Define 'thunk'. Add 'cond-expand' to use 'with-exception-handler' on 'guile-3' and 'catch' otherwise. --- guix/store.scm | 29 +++++++++++++++++++---------- 1 file changed, 19 insertions(+), 10 deletions(-) (limited to 'guix') diff --git a/guix/store.scm b/guix/store.scm index 1dd5c9545b..fb4b92e0c4 100644 --- a/guix/store.scm +++ b/guix/store.scm @@ -623,16 +623,25 @@ connection.
