2014-11-02pidfile: stop making pidfile error a special caseMichael Tokarev1-5/+0
In case of -daemonize, we write non-zero to the daemon pipe only if pidfile creation failed, so the parent will report error about pidfile problem. There's no need to make special case for this, since all other errors are reported by the child just fine. Let the parent report error and simplify logic in os_daemonize(). This way, we don't need os_pidfile_error() function, since it only prints error now, so put the error reporting printf into the only place where qemu_create_pidfile() is called, in vl.c. While at it, fix wrong indentation in os_daemonize(). Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
2014-02-20util: Split out exec_dir from os_find_datadirFam Zheng1-19/+2
With this change, main() calls qemu_init_exec_dir and uses argv[0] to init exec_dir. The saved value can be retrieved with qemu_get_exec_dir later. It will be reused by module loading. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-04-12qemu-timer: move timeBeginPeriod/timeEndPeriod to os-win32Paolo Bonzini1-0/+11
These are needed for any of the Win32 alarm timer implementations. They are not tied to mmtimer exclusively. Jacob tested this patch with both mmtimer and Win32 timers.

Using the main loop code from QEMU enables tools to operate fully asynchronously. Advantages include better Windows portability (for some definition of portability) over glib's. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2011-12-06win32: fix memory leakZhi Hui Li1-0/+7
string is allocated by g_malloc, will not be used after putenv, should be free before return. Paolo Bonzini <pbonzini@redhat.com> confirmed this is safe under Wine: "1) the underlying Win32 APIs require separate arguments for the variable and value; 2) even though in the end Wine stores the environment as name=value (http://source.winehq.org/source/dlls/ntdll/env.c), it does so in a single consecutive block of memory, not as a char* array like POSIX does. While (2) might apply only to Wine, (1) surely applies to Windows as well."

2011-11-09Replace WriteFileEx with WriteFile in qemu_create_pidfileFabien Chouteau1-3/+4
The function that writes pidfile for win32 uses WriteFileEx which is an asynchronous IO function. The arguments given to WriteFileEx are allocated on the stack and one of them is "in out". When the IO operation is actually executed the calling function has already returned, so the arguments are no longer allocated or allocated to another frame.

2011-06-15Introduce format string for pid_tAndreas Färber1-1/+1
BeOS and Haiku on i386 use long for 32-bit types, including pid_t. Using %d with pid_t therefore results in a warning. Unfortunately POSIX:2008 does not define a PRId* string for pid_t. In some places pid_t was previously casted to long and %ld hardcoded. The predecessor of this patch added another upcast for the simpletrace filename but was not applied to date. Since new uses of pid_t with %d keep creeping in, let's instead define an OS-dependent format string and use that consistently.

2010-10-09win32: Set unbuffered stdoutStefan Weil1-0/+6
Win32 does not support line-buffering, but it allows unbuffered output. Unbuffered output is a good approximation. For typical output statements which usually end with '\n', it's even identical. Buffered output is unusable for program traces because of its large delay.
