* build: Prepare config.h for inclusion in examples/testsChris Dickens2020-11-271-0/+4
| | | | | | | | | | | | There are certain games played in the examples and tests source to account for differences in build environments and target platforms. This can be simplified by including config.h and using the definitions there. To that end, move the printf function attribute definition from libusbi.h to config.h and leverage it where it is used in the examples and tests.

* build: Fix Android and Xcode compilation errors/warningsChris Dickens2020-11-163-5/+10
| | | | | | | | | | | | | | | | | | Commit f69548c3b3 ("examples: Enable all examples to build on all platforms") modified dpfp and sam3u_benchmark to be buildable on any platform, however there were some oversights and regressions introduced for Android and Xcode. Update the Android and Xcode build files to account for the removal of dpfp_threaded.c as well as the inclusion of config.h from examples and/or tests source. Additionally switch the threaded version of dpfp to use sem_open() instead of sem_init() as the latter is in fact deprecated on MacOS.

* build: Merge events and threads into single platform abstractionChris Dickens2020-09-121-5/+2
| | | | | | | | | | | | | | The split between events and threads abstractions is unnecessary. Simplify the library by merging the two into a "platform" abstraction. The only meaningful change is that Cygwin builds will no longer use the POSIX threads abstraction but will instead use the native Windows one. The downside to doing this is that the dpfp_threaded example program will no longer be available on Cygwin builds. This should be fine, and future work will make dpfp_threaded available for all forms of Windows build systems. Signed-off-by: Chris Dickens <christopher.a.dickens@gmail.com>
* core: Introduce platform events abstractionChris Dickens2020-08-122-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The way in which system handles or resources are represented differs greatly between Unix-like operating systems and Windows. Ever since Windows support was added to libusb, Windows been emulating principles of Unix-like operating systems such as file descriptors and poll(). This commit introduces an abstraction layer that completely removes the need to perform any emulation. Fundamentally there are three things that each platform provides to libusb: 1) A signallable event 2) A timer (not required, but useful) 3) A means to wait for event sources such as the above to be triggered The POSIX abstraction for Unix-like operating systems uses file descriptors as the "handles" to the underlying system resources. The signallable event is implemented using a pipe, the timer as a timerfd (where supported) and the poll() system call is used to wait for events. The Windows abstraction uses native HANDLEs as the "handles" to the underlying system resources. The signallable event is implemented using a manual-reset event, the timer as a manual-reset waitable timer, and the WaitForMultipleObjects() system call is used to wait for events.

* android: Update makefiles to include recent autobuild changesChris Dickens2020-03-305-55/+57

* build: Require C11 to build and clean up autoconfig/automake filesChris Dickens2020-03-301-10/+13
| | | | | | | | | | | | | | | | | | | | | | | C11 compiler support has been available for many years now. It is not unreasonable to require this now, and doing so allows some cleanup to the configure script. It is no longer necessary to check for compiler support of the '-fvibility' flag because any compiler that supports C11 will support this flag as well. Fix up the way that compiler and linker flags are passed down to the various makefiles. The compiler flags should be shared by all, but the linker flags and libraries should be separated between the library and the examples/tests. The visibility flag is only relevant for the library and the thread flags are only relevant for sources using thread constructs, so provide them as needed. Rearrange configure.ac to group similar functionality and consolidate where possible. Based on these changes, update the Travis configuration file to include newer versions of test platforms to ensure proper C11 compiler support.

* core: Kill the OS_* definitions and use in the source codeChris Dickens2020-03-271-3/+0

* threads_posix: Improve usbi_get_tid() for various platformsChris Dickens2020-03-271-0/+3
| | | | | | | | | | | | | Add support for real thread IDs on macOS 10.6 and later using the new pthread_threadid_np() function. Add support for thread IDs on Haiku, NetBSD and Solaris. Provide a fallback value other than -1 when direct support is not available. This should suffice as a unique identifier since pthread_t, while opaque, is still distinct amongst active threads.

* configure.ac: Cleanup and refactoringChris Dickens2020-01-241-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the formatting consistent across the entire file. In particular: - Always quote strings whose values are derived - Use tabs consistently - Wrap all arguments with square brackets Replace the use of '-a' with '&&' to be more portable. Rearrange some of the feature checks to be conditional upon the platform or backend. For example, there is no need to check for nfds_t on Windows because poll() doesn't exist there. Similarly we now only check for timerfd on Linux and Solaris. This translates into slightly faster configure times. Explicitly define tokens for both the poll and thread implementations. This makes the preprocessor conditionals much nicer since it is not necessary to enumerate all possible OS_* tokens. Also replace POLL_NFDS_TYPE with a proper typedef that is based on the availability of the nfds_t type. Migrate to config definition names that are more consistent with autoconf. The check for timerfd actually verifies the presence of the library function instead of just the header definitions, and the token USBI_TIMERFD_AVAILABLE is now HAVE_TIMERFD. Similarly the check for syslog results in a definition of HAVE_SYSLOG. Signed-off-by: Chris Dickens <christopher.a.dickens@gmail.com>
* Misc: Trim and consolidate header file usageChris Dickens2020-01-241-39/+9
| | | | | | | | | | | | | Refactor libusbi.h to include the set of common header files needed by every main source file in the library and change these source files to include libusbi.h first, followed by any non-common headers. Including libusbi.h first ensures that the config definitions are pulled in and will eliminate redundant includes in the individual sources files. Also clean up some whitespace errors and remove unnecessary definitions in the manually generated config.h files. Signed-off-by: Chris Dickens <christopher.a.dickens@gmail.com>
* core: Remove use of gettimeofday()Chris Dickens2017-01-121-3/+0
| | | | | | | | | | | | | | | | | Prior to this commit, gettimeofday() was being used for timestamps in debug messages. This function has been marked as deprecated in the latest POSIX specification and furthermore is not supported on Windows, thus requiring our own implementation as usbi_gettimeofday(). This commit changes the logging code to obtain timestamps using the clock_gettime() function provided by the backend. The implementation of usbi_gettimeofday() for Windows was actually equivalent to that of the USBI_CLOCK_REALTIME implementation for clock_gettime(), so this eliminates code duplication. In addition, the USBI_CLOCK_REALTIME implementation has been updated for Windows to leverage the timespec_get() function available in VS 2015 and later.
