2015-01-27	Fix bs-nl handling, exit and Environment for VMS.	John Malmberg	1	-1/+5
	This fix required a complete rewrite of the command parser vmsjobs.c child_execute_job. The old parser had too many incorrect assumptions about DCL commands and could not be repaired to extended. The parser now more closely parses VMS commands and handles quoted commands and redirection. Command File mode has been improved, but can not fully support bs-nl syntax. VMS Unix shell simulation has been improved. * commands.c: vms_comma_separator is now a run-time setting. * function.c: vms_comma_separator is now a run-time setting. * function.c(func_basename_dir) now reports "[]" or "./" based on VMS crtl runtime setting. * job.c(start_job_command): VMS Handle empty commands propery. * main.c: Add VMS environment variables for run-time settings. * vms_legacy_behavior - Force older behavior. * vms_comma_separator - Commas or spaces for separators. * vms_unix_simulation - Enhanced Posix shell simulation features. * Detect if VMS CRTL is set to report Unix paths instead of VMS. * ':' and '>' are also MAP_DIRSEP on VMS. * makeint.h: Add VMS run-time option variables. * readme.vms: Update to current behavior. * variable.c(define_variable_in_set): Fix VMS Environment variable lookup. * variable.c(define_automatic_variables): Remove some VMS specific automatic variables and use the Unix ones instead. * vms_export_symbol.c: Set max symbol size correctly. * vmsjobs.c: child_execute_job() complete rewrite of VMS comand parsing. * vmsjobs.c(build_vms_cmd): VMS commmand building with shell simulation.

2014-10-20	[SV 42447]: VMS simulate exporting symbols	John Malmberg	1	-0/+523
	This also includes fixing the most of the exit handling code for VMS. Self tests: Previously about 94 Tests in 36 categories fail. Now about 45 tests in 22 categories fail. Because some tests do not properly clean up, the number of tests that fail can vary by one or two test cases between consecutive runs. * Makefile.am: Add new VMS files. * job.c: add prototype for vms_strsignal(). * job.c: (child_error): Remove VMS specific code as no longer needed. * job.c: (reap_children): The VMS specific code was setting the status to 0 instead of setting it to the proper exit status. * job.h: Add vms_launch_status to struct child. * main.c: (main): Use environment variables for options to use MCR * instead of a foreign command, and to always use command files for subprocesses. For VMS use (set_program_name) routine which is common to ports of other GNU packages to VMS to set the program name used internally. Use (vms_putenv_symbol) to set up symbols to be visible in child programs, including recursive make launched by execve() Start of Bash shell detection code for VMS. * makefile.com: Need nested_include=none for building on VMS search lists. Add vms_progname, vms_exit, and vms_export_symbol. * makefile.vms: Need nested_include=none for building on VMS search lists. Add vms_progname, vms_exit, vms_export_symbol. * makeint.h: Make sure non-standard "VMS" macro is defined. Add prototypes for new VMS routines. Remove VMS-specific failure codes. * vmsjobs.c: Add VMS POSIX exit code constants. (_is_unixy_shell): Detect Bash shell. (vms_strsignal): simulate strsignal() on VMS. (vmsHandleChildTerm): fix to properly report failed LIB$SPAWN() exit status codes. Remove code that duplicated code in job.c. (child_execute_job): Export environment symbols before spawning a child and restore afterward unless option to use command files for subprocesses is set. Improve handling of UNIX null commands ":". * vms_exit.c: Provides vms_exit() to detect if an exit code is UNIX or VMS, and converts the UNIX code into a VMS exit code. * vms_export_symbol.c: Routines to create DCL symbols that work like shell aliases or exported shell symbols and clean them up on exit. * vms_export_symbol_test.com: Unit test for vms_export_symbol.c * vms_progname.c: New file: VMS specific replace for progname.c that is used in some GNU projects.
