From 93ba78d6f4632ef1c5228965e3edc8c0faf88c1e Mon Sep 17 00:00:00 2001 From: Vincent Ambo Date: Tue, 26 May 2020 00:06:52 +0100 Subject: revert(3p/git): Revert merge of git upstream at v2.26.2 This causes cgit to serve error pages, which is undesirable. This reverts commit 5229c9b232de5bfa959ad6ebbb4c8192ac513352, reversing changes made to f2b211131f2347342dde63975b09cf603149f1a3. --- third_party/git/sigchain.h | 45 --------------------------------------------- 1 file changed, 45 deletions(-) (limited to 'third_party/git/sigchain.h') diff --git a/third_party/git/sigchain.h b/third_party/git/sigchain.h index 8e6bada8928c..138b20f54b40 100644 --- a/third_party/git/sigchain.h +++ b/third_party/git/sigchain.h @@ -1,57 +1,12 @@ #ifndef SIGCHAIN_H #define SIGCHAIN_H -/** - * Code often wants to set a signal handler to clean up temporary files or - * other work-in-progress when we die unexpectedly.
