2010-10-13vnc: avoid write only variablesBlue Swirl1-0/+8
Compiling with GCC 4.6.0 20100925 produced warnings: /src/qemu/ui/vnc.c: In function 'vnc_client_cache_auth': /src/qemu/ui/vnc.c:217:12: error: variable 'qdict' set but not used [-Werror=unused-but-set-variable] /src/qemu/ui/vnc.c: In function 'vnc_display_open': /src/qemu/ui/vnc.c:2526:9: error: variable 'acl' set but not used [-Werror=unused-but-set-variable] Fix by making the variable declarations and their uses also conditional to debug definition.

2010-08-22vnc: check fd before calling qemu_set_fd_handler2() in vnc_client_write()Yoshiaki Tamura1-1/+1
Setting fd = -1 to qemu_set_fd_handler2() causes bus error at FD_SET in main_loop_wait(). Signed-off-by: Yoshiaki Tamura <tamura.yoshiaki@lab.ntt.co.jp> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-07-26vnc: add missing lock for vnc_cursor_define()Corentin Chary1-0/+2
All vnc_write() calls must be locked (except the ones present before the protocol initialization). Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-07-26vnc: threaded VNC serverCorentin Chary1-24/+120
Implement a threaded VNC server using the producer-consumer model. The main thread will push encoding jobs (a list a rectangles to update) in a queue, and the VNC worker thread will consume that queue and send framebuffer updates to the output buffer. The threaded VNC server can be enabled with ./configure --enable-vnc-thread. If you don't want it, just use ./configure --disable-vnc-thread and a syncrhonous queue of job will be used (which as exactly the same behavior as the old queue). If you disable the VNC thread, all thread related code will not be built and there will be no overhead.

2010-07-26vnc: encapsulate encoding membersCorentin Chary1-4/+4
This will allow to implement the threaded VNC server in a more cleaner way. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-07-26vnc: tight add PNG encodingCorentin Chary1-4/+7
Introduce a new encoding: VNC_ENCODING_TIGHT_PNG [1] (-269) with a new tight filter VNC_TIGHT_PNG (0x0A). When the client tells it supports the Tight PNG encoding, the server will use tight, but will always send encoding pixels using PNG instead of zlib. If the client also told it support JPEG, then the server can send JPEG, because PNG will only be used in the cases zlib was used in normal tight. This encoding was introduced to speed up HTML5 based VNC clients like noVNC [2], but can also be used on devices like iPhone where PNG can be rendered in hardware.

2010-07-26ui: move all ui components in ui/Corentin Chary1-0/+2631
Move sdl, vnc, curses and cocoa UI into ui/ to cleanup the root directory. Also remove some unnecessary explicit targets from Makefile. aliguori: fix build when srcdir != objdir Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
