ash: redir: Retry open on EINTR

2025-08-09T18:17:31+00:00

Upstream commit: Date: Thu, 28 May 2020 21:31:45 +1000 redir: Retry open64 on EINTR It is possible for open64 to block on named pipes, and therefore it can be interrupted by signals and return EINTR. We should only let it fail with EINTR if real signals are pending (i.e., it should not fail on SIGCHLD if SIGCHLD has not been trapped). This patch adds a new helper sh_open to retry the open64 call if necessary. It also calls sh_error when appropriate.

shell: improve bash compatibility of read built-in

2025-07-01T18:21:37+00:00

Make the read built-in more compatible with bash: - Return an exit code of 142 on timeout. - When the timeout expires before a newline is detected in the input bash captures the partial input. This behaviour is new since bash version 4.4. BusyBox shells had the pre-4.4 behaviour where the input was lost. Update the tests to suit and fix a couple of compiler errors in the testsuite. function old new delta builtin_read 154 174 +20 readcmd 213 228 +15 shell_builtin_read 1364 1370 +6 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 3/0 up/down: 41/0) Total: 41 bytes Signed-off-by: Ron Yorston Signed-off-by: Denys Vlasenko
