* job.c (construct_command_argv_internal): If shell wildcard
characters are found inside a string quoted with "..", give up the
fast route and go through the shell. Fixes Savannah bug #44348.

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.

This fixes VMS implicit rules and UNIX style pathname handling.
It also fixes some of the VMS style pathname handling, more work
there will be needed later.
TODO: There are other case insensitive platforms besides VMS.
We need to find out why there is extra VMS code for this. This
indicates either the extra VMS code is not needed, or the case
insensitive support may not be complete on the other case
insensitive platforms.
* default.c: Add missing definitions to default_suffix_rules[] and
default_variables[].
TODO: As it is important that VMS DCL mode definitions must always
be a superset of UNIX definitions, a better way of maintaining the
VMS DCL mode definitions should be devised.
* dir.c (downcase_inplace): Add a reentrant downcase() routine.
Add future support for VMS 8.2+ _USE_STD_STAT macro which will
disable a lot of VMS specific code from compiling.
(dir_file_exists_p): vmsify filename only if directory name has VMS
directory delimiters.
(file_exists_p): Handle both VMS and UNIX directories.
(file_impossible): Handle both VMS and Unix directories. Track
whether a VMS format path is needed for the return value.
* file.c (lookup_file): Check if vmsify is needed; handle UNIX paths.
* implicit.c (pattern_search): Enable UNIX paths.
* read.c (parse_file_seq): Enable UNIX paths.
* remake.c (f_mtime): Fix gpath_search call for VMS paths.
* rule.c (count_implicit_rule): Enable UNIX paths, Fix VMS paths.
* vpath.c (selective_vpath_search): Enable UNIX paths.
|
|
* NEWS: Merge in VMS history.
* README.VMS: Remove VMS history, document current behavior and
known issues.
|

Upated to match change to run_make_tests and some future fixes to
make on VMS.
* arscan.c: Use ANSI compatible pragmas instead of VAX C extensions.
* tests/scripts/features/archives: Fix tests to use VMS rules and
answers when running on VMS and using DCL as a shell.
* tests/scripts/features/vpath3: Fix epected answer on test when
run on VMS.
* tests/scripts/vms/library: (New) Test the VMS library rules that
are not tested by existing tests.

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.
|
|
* run_make_tests.pl: set $port_type to be 'VMS-DCL' when the test are
run from the VMS DCL Interpreter. When the tests are run from GNV
on VMS, the $port_type will be 'UNIX'.
* run_make_tests.com: VMS search list support. This is needed for
using a search list such as prj_root = lcl_root:,vms_root:,src_root:
for building and testing.

* main.c (find_and_set_default_shell, main) [WINDOWS32]: Declare
variables 'const char *' to avoid compiler warnings.
* job.c (construct_command_argv_internal) [!NDEBUG]: Declare 'end'
and set it only if NDEBUG is not defined, to avoid compiler
warnings.

* ar.c: fix VMS library search for members, which do not have
suffixes, aka filename extensions.
* arscan.c: fix time conversion and library callback routines.
* default.c: more suffixes and automatically create the VMS library
if it doesn't exists.
|
|
* config.h-vms.template: add feature macro USE_DCL_COM_FILE to always
write a DCL command file, enabled by default.
* vmsjobs.c: with USE_DCL_COM_FILE enabled write make variables as DCL
symbol assignments into the command file. This enables printing
directory and make level info for recursive use of make. This also
enables forced DCL symbol substitution in the actions.
|
|
* function.c: add VMS code to func_notdir_suffix and func_basename_dir
to work on comma separated lists; this fixes the expansion of
$(^D), $(+D) and the F variants for VMS.
|
|
|
|
* job.c, vmsjobs.c: fix some double quote and new line handling;
implement ONESHELL with writing multiple lines into one DCL command
procedure; in ONESHELL allow VMS/make internal redirection only on the
first line; fix the created DCL command procedure, which didn't abort
on errors; return correct exit status from the DCL command procedure;
preserve current procedure verification; make the generated command
procedure more robust.

which ensures that the VMS/DCL ECHO ("write sys$output") is used
and is correctly quoted.
* vmsjobs.c: remove unused builtin 'rm'.
|
|
Moved into tests directory.
|
|
* config.h-vms.template: make sure the CRTL version is known
