From: Corinna Vinschen <corinna@sourceware.org> To: newlib-cvs@sourceware.org Subject: [newlib-cygwin] Restore _lock initialization in non-single threaded mode Date: Wed, 31 Aug 2022 08:07:24 +0000 (GMT) [thread overview] Message-ID: <20220831080724.95A983852741@sourceware.org> (raw) https://sourceware.org/git/gitweb.cgi?p=newlib-cygwin.git;h=dd1122e21cb4ea78ce4c5894787c8f085469f9dd commit dd1122e21cb4ea78ce4c5894787c8f085469f9dd Author: Torbjörn SVENSSON <torbjorn.svensson@foss.st.com> Date: Tue Aug 30 15:54:53 2022 +0200 Restore _lock initialization in non-single threaded mode When __SINGLE_THREAD__ is not defined, stdin, stdout and stderr needs to have their _lock instance initialized. The __sfp() method is not invoked for the 3 mentioned fds thus, the std() method needs to handle the initialization of the lock. This is more or less a revert of 382550072b49430f8c69adee937a0ba07bd385e6 Contributed by STMicroelectronics Signed-off-by: Torbjörn SVENSSON <torbjorn.svensson@foss.st.com> Diff: --- newlib/libc/stdio/findfp.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/newlib/libc/stdio/findfp.c b/newlib/libc/stdio/findfp.c index c43028209..2cc549537 100644 --- a/newlib/libc/stdio/findfp.c +++ b/newlib/libc/stdio/findfp.c @@ -88,6 +88,10 @@ std (FILE *ptr, #else /* _STDIO_CLOSE_STD_STREAMS */ ptr->_close = NULL; #endif /* _STDIO_CLOSE_STD_STREAMS */ +#ifndef __SINGLE_THREAD__ + if (ptr == &__sf[0] || ptr == &__sf[1] || ptr == &__sf[2]) + __lock_init_recursive (ptr->_lock); +#endif #ifdef __SCLE if (__stextmode (ptr->_file)) ptr->_flags |= __SCLE;
