From da7df54309eb759837a289ade900fe8e3d6ddc36 Mon Sep 17 00:00:00 2001 From: Eli Zaretskii Date: Sat, 27 Apr 2013 14:20:49 +0300 Subject: Support --output-sync on MS-Windows. w32/compat/posixfcn.c: New file, with emulations of Posix functions and Posix functionality for MS-Windows. w32/subproc/sub_proc.c: Include io.h. (process_noinherit): New function, forces a file descriptor to not be inherited by child processes. (process_easy): Accept two additional arguments, and use them to set up the standard output and standard error handles of the child process. w32/include/sub_proc.h (process_easy): Adjust prototype. (process_noinherit): Add prototype. read.c [WINDOWS32]: Include windows.h and sub_proc.h. makeint.h (LOCALEDIR) [WINDOWS32}: Define to NULL if not defined. This is needed because the MS-Windows build doesn't have a canonical place for LOCALEDIR. (WIN32_LEAN_AND_MEAN) [WINDOWS32]: Define, to avoid getting from windows.h header too much stuff that could conflict with the code. main.c : New static variable. : Add support for "--sync-mutex" switch. (decode_output_sync_flags): Decode the --sync-mutex= switch. (prepare_mutex_handle_string) [WINDOWS32]: New function. (main): Add "output-sync" to .FEATURES. job.h (CLOSE_ON_EXEC) [WINDOWS32]: Define to call process_noinherit. (F_GETFD, F_SETLKW, F_WRLCK, F_UNLCK, struct flock) [WINDOWS32]: New macros. (RECORD_SYNC_MUTEX): New macro, a no-op for Posix platforms. (sync_handle_t): New typedef. job.c : Change type to sync_handle_t. (FD_NOT_EMPTY): Seek to the file's end. Suggested by Frank Heckenbach . (pump_from_tmp_fd) [WINDOWS32]: Switch to_fd to binary mode for the duration of this function, and then change back before returning. (start_job_command) [WINDOWS32]: Support output_sync mode on MS-Windows. Use a system-wide mutex instead of locking stdout/stderr. Call process_easy with two additional arguments: child->outfd and child->errfd. (exec_command) [WINDOWS32]: Pass two additional arguments, both -1, to process_easy, to adjust for the changed function signature. function.c (windows32_openpipe) [WINDOWS32]: This function now returns an int, which is -1 if it fails and zero otherwise. It also calls 'error' instead of 'fatal', to avoid exiting prematurely. (func_shell_base) [WINDOWS32]: Call perror_with_name if windows32_openpipe fails, now that it always returns. This avoids a compiler warning that error_prefix is not used in the MS-Windows build. config.h.W32.template (OUTPUT_SYNC): Define. build_w32.bat: Add w32/compat/posixfcn.c to compilation and linking commands. From Frank Heckenbach : job.c (sync_output): Don't discard the output if acquire_semaphore fails; instead, dump the output unsynchronized. --- makeint.h | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'makeint.h') diff --git a/makeint.h b/makeint.h index 976b040..d1b00c6 100644 --- a/makeint.h +++ b/makeint.h @@ -355,6 +355,14 @@ extern int no_default_sh_exe; /* is default_shell unixy? */ extern int unixy_shell; + +/* We don't have a preferred fixed value for LOCALEDIR. */ +# ifndef LOCALEDIR +# define LOCALEDIR NULL +# endif + +/* Include only the minimal stuff from windows.h. */ +#define WIN32_LEAN_AND_MEAN #endif /* WINDOWS32 */ #if defined(HAVE_SYS_RESOURCE_H) && defined(HAVE_GETRLIMIT) && defined(HAVE_SETRLIMIT) -- cgit v1.2.3
