This is required by newer mingw toolchain versions which demand that
winsock2.h is included before windows.h. Now, due to the use of
socket definitions in pth.h we need to include winsock2.h also in
pth.h, now pth.h is often included after an include of windows.h and
thus the compiler spits out a warning. To avoid that we include
winsock2.h at all places the compiler complains about.
* common/estream.c (ESTREAM_MUTEX_LOCK): Cast pth_mutex_acquire result
to void. Some compilers choke on mixing void and int in an
conditional operator. Reported by Nelson H. F. Beebe.
Fabian Keil found the reason for a SIGBUS:
In the "gpg-agent --daemon" case, main() calls pth_kill()
after the client has been forked, so when es_deinit() is
called on exit, acquiring the estream_list_lock seems to
cause pth to dereference a pointer located in a memory
region that has previously been free()'d.
My approach to fix it is different than his suggestion. It should
allow to continue all estream operations after a pth_kill except for
restarting pth.
char * vs. unsigned char * warnings. The GNU coding standards used to
say that these mismatches are okay and better than a bunch of casts.
Obviously this has changed now.
* gpg-agent.c: New option --write-env-file.
* gpg-agent.c (handle_connections): Make sure that the signals we
are handling are not blocked.Block signals while creating new
threads.
* estream.c: Use HAVE_CONFIG_H and not USE_CONFIG_H!
(es_func_fd_read, es_func_fd_write): Protect against EINTR.
* gpg-agent.texi (Agent UPDATESTARTUPTTY): New.
* scdaemon.c (handle_connections): Make sure that the signals we
are handling are not blocked.Block signals while creating new
threads.
(handle_connections): Include the file descriptor into the name of
the thread.
