- fixed invalid, missing or additional arguments
- removed all type casts from arguments
- added missing (void*) typecasts for %p arguments
- use inttypes defines where appropriate
On some operating systems sched_yield is a stub returning returning -1.
In that case use usleep which should at least trigger a context switch
if any thread is waiting.
Since the current winpr implementation for overlapped operations is
incomplete and buggy, all affected functions will now fail if they are
called with a set FILE_FLAG_OVERLAPPED flag or a non-null pointer to
a OVERLAPPED structure.
winpr/nt:
- use proper one-time initialization on win32
- fix TestNtCreateFile
- fix broken/incomplete _RtlAnsiStringToUnicodeString
- unimplemented functions return appropriate error codes
winpr/pipe:
- improved TestPipeCreateNamedPipe
- rewrite the completely broken TestPipeCreateNamedPipeOverlapped test
rdtk:
- improve test and don't blindly return success
winpr/synch:
- fix race condition in TestSynchTimerQueue
winpr/ssspi:
- fix TestEnumerateSecurityPackages printf output
- fix TestQuerySecurityPackageInfo printf output
winpr/environment:
- fix GetEnvironmentStrings printf output
winpr/comm:
- unimplemented functions return appropriate error codes
winpr/io:
- unimplemented functions return appropriate error codes
winpr/thread:
- implement SwitchToThread() via sched_yield()
* expose EnvironmentBlockToEnvpA
* cleanup includes in process.c
* removed unused "flag" variable in _CreateProcessExA
* make ProcessHandleCloseHandle static
When launching a new process stdin/stdout/stderr can be redirected by
passing the corresponding HANDLEs in the passed lpStartupInfo structure.
This is required for example if a pipe should be used as stdin/stdout.
If set in lpStartupInfo the file descriptor of the passed handle is
now used. The test was updated accordingly.
winsock.h pulls in a lot of defines and dependencies that are not
required and partially unwanted in winpr's core (for parts that are not
related to network). In order to get rid of this dependency and have an
independent defines for extended winpr functions the WINPR_FD_* defines
are used internally (and for exposed functions). Where required, like in
WSAEventSelect, the FD_* is mapped to WINPR_FD_*.
If SA_SIGINFO isn't set in the flags sa_handler is used
instead of sa_sigaction.
This fixes also the compiler warning:
FreeRDP/winpr/libwinpr/thread/process.c: In function ‘_CreateProcessExA’:
FreeRDP/winpr/libwinpr/thread/process.c:282:20: warning: assignment from
incompatible pointer type [enabled by default]
The calling thread of CreateProcess can be in any library and
can have arbitrary signal masks and handlers.
We now save the caller's mask and block all signals before forking.
After fork:
- child resets the handlers and unblocks all signals.
- parent restores the caller's original signal mask.
- added the unit test: TestThreadExitThread
- fix: ensure thread_list to be up to date before to call ExitThread()
- possibly resolved: Problems with serial redirection #2389
* shell: add missing NULL checks
* thread: handle case where HAVE_EVENTFD_H isn't defined
* wlog: return NULL instead of 0
* wlog: use g_RootLog instead of WLog_GetRoot
otherwise a new root might be initialized on uninit
* indentation and style fixes
TerminateProcess shouldn't call kill if the PID is <=0 because this has
unwanted effects (and is not what TerminateProcess should do):
* with PID == 0 any process in the same process group gets the signal
sent
* with PID == -1 *every* processes that the running users has
permissions to gets the signal sent
* with PID < -1 the process within the same process group and -PID gets
the signal send
For more details see kill(2).
