* Cygwin: Remove recursive configureJon Turney2020-11-205-5330/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's doesn't seem to be much use in independently distributing these subdirectories, so allowing them to be independently configured seems pointless and overcomplicated. The order in which the subdirectories are built is still a little odd, as cygwin is linked with libcygserver, and cygserver is then linked with cygwin. So, we build the cygwin directory first, which invokes a build of libcygserver in the cygserver directory, and then build in the cygserver directory to build the cygserver executable. Drop AC_CONFIGURE_ARGS, since we don't need to recursively call configure with the same arguments anymore. Slightly refine when we build utils: Previously we didn't build any utils if MinGW compiler use was avoided, now we just avoid building those utils which require that compiler. Greatly simplify how winsup_srcdir and target_builddir are set, since we're only configuring from one directory. (These are still kept absolute, since we don't adjust them where used for being used in a subdirectory). Remove configure.cygwin and put it's (greatly reduced) contents inline in the one place it's used now. Remove generated configure and aclocal.m4 in subdirectories.
* Cygwin: Drop autoconf variable all_hostJon Turney2020-11-022-23/+0
| | | | | | | | The autoconf variable all_host is used to make building of the stub library used by the testsuite conditional on not cross-compiling. Make it unconditional, so we will notice if it's broken when cross-compiling.
* Cygwin: Restore setting CC and CXX Makefile variablesJon Turney2020-10-281-0/+3
| | | | | | | | | | | b55e3f19 was a bit too aggressive in dropping, rather than just un-exporting these Makefile variables. We need to set these to the configured host compiler if we are cross-compiling, otherwise they default to the build compiler. Also export CC to the mkvers.sh script (which requires it since 4eca5e6a). It's unclear why we can't just cause windres to use the build 'cpp' as the pre-processor there.
* Cygwin: Drop do-nothing install_host targetJon Turney2020-10-212-7/+0
| | | | | Drop do-nothing install_host target, which is only used when not cross-compiling.

* Cygwin: Use aclocal option --system-acdir rather than --acdirJon Turney2020-10-181-1/+1
| | | | | | In autogen.sh, use 'aclocal --system-acdir' rather than 'aclocal --acdir'. '--acdir' was deprecated in automake 1.11 and removed in automake 1.13.

* Cygwin: Remove ccwrapJon Turney2020-10-183-25/+16
| | | | | | | | | | | | | | ccwrap massages the compiler's standard include directories to remove '/usr/include/w32api', with the intent of allowing it to be overriden by '--with-windows-headers' (See 4c36016b). I'm not 100% convinced that this is always working as desired, since in some places w32api includes are done using <w32api/something.h>, which will find them via the path /usr/include. If this does turn out to be needed, this could also be implemented by constructing the appropriate compiler flags once, rather than on every compiler invocation.
* Cygwin: Remove AC_PROG_MAKE_SETJon Turney2020-10-142-35/+0
| | | | | | | | This is only needed if we are using an ancient make which doesn't set ${MAKE}, but we say "This makefile requires GNU make." everywhere. It only has an effect if @SET_MAKE@ is used, which we aren't doing consistently.
* Cygwin: Drop looking for w32api in winsup/w32apiJon Turney2020-10-142-4/+0
| | | | | Stop looking for w32api headers in the (no longer existent) winsup/w32api directory (removed in commit 61746d6ae850).

* cygserver: Speed up non-debug scenarioCorinna Vinschen2017-03-247-16/+30
| | | | | | | | | _log/_vlog were always called so we always had a function call hit even if we're not debugging. Expand on the debugging macros so the decision to call _log/_vlog is done in the caller already. Also, make a log level difference between syscall_printf and system_printf.

* cygserver: Revamp thread sleep handlingCorinna Vinschen2017-03-245-99/+71
| | | | | | | | | | | | | | | | | | | | The current implementation is a very simple approach to implement a statically sized sleep queue. The problem is that this code requires a certain amount of synchronization because the slots in the queue are used dynamically. To top it off, the Event objects used for sync'ing are created and destroyed on demand. This is complicated, slow, and error prone. There's also a blatant bug here: The number of slots in the queue was wrongly computed in size. It was too small if XSI IPC was used a lot. Make the code more robust. Let the queue have the right size. Every slot is now used for a specific IPC object. All sync objects (switched to Semaphores) are only created when first required, but never destroyed. This reduces the usage of a critical section to the creation of a new sync object. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* cygserver: raise number of worker threads on demandCorinna Vinschen2017-03-242-12/+11
| | | | | | | | | | | | | The number of threads in the worker pool is fixed so far. This is a problem in XSI IPC scenarions with an unknown number of consumers. It doesn't make sense to make the pool very big for a start, but when the need arises, we need to make sure we can serve the request even if all other worker threads are in a wait state. This patch changes threaded_queue to just add another worker thread if all current workers are busy. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Rename without-mingw-progs to with-cross-bootstrapPeter Foley2016-04-042-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rename without-mingw-progs to with-cross-bootstrap, since it now disables additional checks that are problematic for cross-compilers. When cross-compiling a toolchain targeting cygwin, building cygwin1.dll requires libgcc. However, building libgcc requires the cygwin headers to be installed. Configuring cygwin requries the mingw-crt libraries, which require the cygwin headers to be installed. Work around this circular dependency by making the --with-cross-bootstrap configure option skip cygwin's configure checks for valid mingw-crt libraries. Cygwin will still properly link against these libraries if they exist, but this allows configure to succeed even if the libraries have not been built yet. Since the mingw-crt libraries only require the cygwin headers to be installed, this allows us to successfully configure cygwin so that we can only install the headers without trying to build any libraries. winsup/ChangeLog configure.ac: rename without-mingw-progs option to with-cross-bootstrap configure: regenerate winsup/cygserver/ChangeLog configure.ac: don't check AC_WINDOWS_LIBS when using with-cross-bootstrap configure: regenerate winsup/cygwin/ChangeLog configure.ac: don't check AC_WINDOWS_LIBS when using with-cross-bootstrap configure: regenerate Signed-off-by: Peter Foley <pefoley2@pefoley.com>
