output.c [WINDOWS32]: Include windows.h and sub_proc.h, to avoid
compiler warnings for CLOSE_ON_EXEC.

We are restarting with the original command line flags, so if we set
MAKEFLAGS as well that will cause double flags.

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.
|

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.

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.

Makes the code a little clearer/cleaner, and solves a problem on systems
where a char is unsigned by default.
|
|
This global variable could be modified during recursion so keep our
own local copy to compare against.
|
|
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.

build_w32.bat (LinkGCC): Prevent a comment from being displayed
at build time.
|
|
job.c (construct_command_argv_internal) [WINDOWS32]: Use
case-insensitive comparison with internal commands of non-Unix
shells.
|
|
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.

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.

|
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.

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 "- ".

w32/Makefile.am (libw32_a_SOURCES): Add compat/posixfcn.c.
configure.ac (OUTPUT_SYNC): Define for mingw32 target.
|
|
job.c (construct_command_argv_internal) <sh_cmds_dos> [WINDOWS32]: Add
"move". Fixes Savannah bug #30714.
|
|
guile.c: Move inclusion of makeint.h before gnumake.h. This
order must be observed when building Make, because gnumake.h must
be included with GMK_BUILDING_MAKE defined, which makeint.h
already does. Otherwise, the linker will look for, and fail to
find, gmk_* functions in some external dynamic library.
|
|
main.c (prepare_mutex_handle_string): Define conditioned on OUTPUT_SYNC.
|
|
build_w32.bat: Copy config.h.W32 to config.h regardless of
whether or not we are building from SCM.
|

This pointer is almost never needed, and it increases the size of the filedef
struct for all files (of which there are a huge number for large builds).
Instead keep a bit field marking whether the file is a loaded object and if so
call a new function to unload it. In load.c we keep a simple linked list of
loaded objects (of which there will be very few typically) and their dlopen()
pointers.

If -R is set in the makefile and not the command line, then go through all the
default variables and undefine them. If -r is set in the makefile and not in
the command line, then remove all .SUFFIX prefixes (unless the user set it)
and SUFFIX variable setting. In -p mode don't print builtins.
|
|
Fixes Savannah bug #2216.
|
|
This mode replaces the previous heuristic setting enabled with -O, where we
would log directory enter/leave for each synchronized output. Now we only
do that if --trace=dir is given.
|
|
job.c (child_out): Output the newline following the message
before fllush-ing the stream. Avoids displaying the following
failure message, which goes to stderr, on the same line.
|
|
gnumake.h (GMK_EXPORT) [_WIN32]: Move the dllexport declaration
here from makeint.h.
makeint.h (GMK_BUILDING_MAKE) [WINDOWS32]: Define before
including gnumake.h.
|
|
shared objects on MS-Windows.

Please drop this patch. Enabling 'subdir-objects' would require
sublter changes to several other parts of the build system that I
don't know how to test properly. We should only enable the
'silent-rules' option for the moment. The updated patch below
does this.
Sorry for the noise,
Stefano

Subject: [PATCH] build: enable the 'silent-rules' automake options
* configure.ac (AM_INIT_AUTOMAKE): Here. The future major Automake
version 2.0 (ETA about one, one and half year from now) will enable
it by default, so better prepare ourselves.
