From 15b6c2a965e66084f3be2e88439dba408f7613ab Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Sat, 24 Apr 2021 18:07:09 +0200 Subject: http-client: Remove exception mishandling in 'http-multiple-get'. Partly fixes . Reported by Florian Pelz . The non-tail recursive call to 'connect' could cause requests to be processed twice, with 'p' possibly closed the second time. Regression introduced in 205833b72c5517915a47a50dbe28e7024dc74e57 and carried over in 45fce38fb0b6c6796906149ade145b8d3594c1c6. * guix/http-client.scm (http-multiple-get): Remove call to 'close-port' and recursive call to 'connect' when the 'write-request' block returns #f. --- guix/http-client.scm | 17 ++++++++--------- 1 file changed, 8 insertions(+), 9 deletions(-) diff --git a/guix/http-client.scm b/guix/http-client.scm index bb1b0eeb56..10bc278023 100644 --- a/guix/http-client.scm +++ b/guix/http-client.scm @@ -214,15 +214,14 @@ returning." ;; Inherit the HTTP proxying property from P.
