From 8bf4becf0c1e4b4ca56dab3501f9cd3da3362215 Mon Sep 17 00:00:00 2001 From: Lars Schneider Date: Fri, 27 Nov 2015 10:15:14 +0100 Subject: [PATCH] add "ok=sigpipe" to test_must_fail and use it to fix flaky tests t5516 "75 - deny fetch unreachable SHA1, allowtipsha1inwant=true" is flaky in the following case: 1. remote upload-pack finds out "not our ref" 2. remote sends a response and closes the pipe 3. fetch-pack still tries to write commands to the remote upload-pack 4. write call in wrapper.c dies with SIGPIPE The test is flaky because the sending fetch-pack may or may not have finished writing its output by step (3). If it did, then we see a closed pipe on the next read() call. If it didn't, then we get the SIGPIPE from step (4) above. Both are fine, but the latter fools test_must_fail. t5504 "9 - push with transfer.fsckobjects" is flaky, too, and returns SIGPIPE once in a while. I had to remove the final "To dst..." output check because there is no output if the process dies with SIGPIPE. Accept such a death-with-sigpipe also as OK when we are expecting a failure.
