2015-03-24Option --sun to enable syntax and features of SunOS makeIgor Pashev1-0/+14
2015-01-27Fix bs-nl handling, exit and Environment for VMS.John Malmberg1-24/+102
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* main.c (main): [SV 43434] Handle NULL returns from ttyname().Paul Smith1-5/+10
2014-10-20[SV 42447]: VMS simulate exporting symbolsJohn Malmberg1-8/+48
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.

2013-10-18Fix initialization of stringlist variables for jobserver_fds and sync_mutex.Christian Boos1-4/+6
(tiny change) main.c (prepare_mutex_handle_string, main): Initialize stringlist variables with at least 2 members, as one member is not currently supported.
2013-10-05Sanitize the registered function interface.Paul Smith1-1/+6
Expand the characters which are legal in a function name, and check the name for validity. Create a type for the function pointer. Convert the last argument from a boolean to flags, to allow for expansion.
2013-09-30Final fixes for obscure output-sync errors.Paul Smith1-40/+38
2013-09-29Reset GNUMAKEFLAGS after parsing.Paul Smith1-1/+9
If we don't do this we'll continually add flags on recursion. This is mainly for users to set in their environment before invoking make.
2013-09-22Add VMS port updates from Hartmut Becker.Paul Smith1-1/+1

2013-09-15[SV 39203] Don't set MAKEFLAGS when restarting.Paul Smith1-12/+6
We are restarting with the original command line flags, so if we set MAKEFLAGS as well that will cause double flags.
2013-09-14[SV 35248] Add --debug "n" flag to turn off current debug options.Paul Smith1-1/+10
2013-09-14[SV 33134] Don't try to close stdout when it's already closed.Paul Smith1-4/+0
2013-09-14Support the -Orecurse option properly.Paul Smith1-36/+19
In this mode we still collect all the output from a given target and dump it at once. However we don't treat recursive lines any differently from non-recursive lines. Also we don't print enter/leave messages after every dump. However we do ensure that we always print them once to stdout, so the parent make will collect it properly.
2013-09-12Enhance the output sync mode.Paul Smith1-93/+7
Create a new file, output.c, and collect functions that generate output there. We introduce a new global context specifying where output should go (to stdout or to a sync file), and the lowest level output generator chooses where to write output based on that context. This allows us to set the context globally, and all operations that write output (including functions like $(info ...) etc.) will use it. Removed the "--trace=dir" capability. It was too confusing. If you have directory tracking enabled then output sync will print the enter/leave message for each synchronized block. If you don't want that, disable directory tracking.
2013-07-22[Bug #39310] Parse simple pattern prereqs for globbing.Paul Smith1-1/+1
We tried to get some efficiency by avoiding a parse_file_seq() for simple pattern prerequisites, but this also means no wildcard expansion was happening, so add it back. Add regression tests for wildcards in target and prerequisite lists.
2013-07-21[Bug #39158] Source cleanups suggested by cppcheck utility.Paul Smith1-2/+1
2013-07-14Modify the update_status field in struct file to be an enum.Paul Smith1-30/+20
Makes the code a little clearer/cleaner, and solves a problem on systems where a char is unsigned by default.
2013-06-28Set O_APPEND mode for stdout/stderr and output-sync temporary files.Paul Smith1-0/+6
POSIX does not guarantee that writes will be atomic if a file is opened for normal (non-append) output. That means if multiple processes are writing to the same file, output could be lost. I can't think of a real use-case where we would NOT want append for stdout/stderr, so force it if we can.
2013-06-22Fix a fatal error at startup on Windows due to non-ASCII characters in PATH.Eli Zaretskii1-9/+12
main.c (find_and_set_default_shell): Don't use file_exists_p or dir_file_exists_p, as those call readdir, which can fail if PATH includes directories with non-ASCII characters, and that would cause Make to fail at startup with confusing diagnostics. See https://sourceforge.net/mailarchive/message.php?msg_id=30846737 for the details.
2013-06-22Create a character map to use for locating stop-points in strings.Paul Smith1-2/+46
In various places we were passing flags and characters to compare, then using complex conditionals to see where to stop in string searches. Performance numbers reveal that we were spending as much as 23% of our processing time in these functions, most of it in the comparison lines. Instead create a character map and use a single bitwise comparison to determine if this is any one of the stop characters.
2013-06-21Disable database verification unless debug enabled.Paul Smith1-40/+47
The database verification can take a long time. Only enable it if debug mode is enabled. If MAKE_MAINTAINER_MODE is set, it's also enabled by default.

2013-05-26[SV #39028] Fix some small typos in messages.Paul Smith1-1/+1
2013-05-22Force version printing whenever we print the database.Paul Smith1-3/+4
2013-05-22Make MFLAGS and MAKEFLAGS more reliable and predictable.Paul Smith1-115/+80
Ensure all simple flags are kept in the initial batch of flags. Do not allow any flags with options in that batch. If there are only non-simple flags ensure MAKEFLAGS begins with " ". Don't let MFLAGS start with "- ".
