Update for 0.5.3 release

5

Fix generation of ChangeLog with VPATH build

6

7

Remove trailing whitespace

8

9

Only put examples in gtk3 based devel RPM

10

The example programs which use introspection are only compatible

11

with GTK3, so should be in gtk-vnc2-devel rather than gtk-vnc-devel

12

13

Remove execute permission from example programs in RPM

14

Avoid getting pointless RPM deps by removing the execute

15

permission from the example programs.

16

17

Add explicit dep on libgcrypt-devel RPM

18

gnutls-devel no longer pulls in libgcrypt-devel since the

19

switch to use nettle.

Block all accelerators when grabbing keyboard

24

Prevent any global accelerators from activating in the

25

gvncviewer demo program when keyboard grab is active

29

Don't ungrab pointer on leave-notify events

30

If we ungrab the pointer on leave-notify events, this breaks

31

the automatic grabs when a button is pressed in absolute pointer.

32

A symptom of this is that if you press to start highlighting text

33

in a gedit window in a server, and move the mouse outside the VNC

34

widget and release the button, the server will never see the mouse

35

up event. We must preserve grabs upon button press so that the

36

VNC server always sees the eventual release events.

37

39

40

Don't drop mouse events that are out of bounds

41

In absolute mode, if the mouse cursor goes outside the bounds

42

of the window, we drop the motion event entirely. This is bad

43

because only one of the co-ordinates may be out of bounds, and

44

the server still wants to see movement in the other axis. Instead

45

of dropping the events, just clamp co-ordinates to the boundary.

Fix typo in NO_UNDEFINED_FLAGS name

50

Fix typo in the configuration of the NO_UNDEFINED_FLAGS name for Cygwin.

51

52

test for --no-undefined linker flag

53

Currently the code assumes that all non-Windows like platforms have a

54

linker that supports --no-undefined, however llvm based compilers do not

55

support this on Linux or Mac OS X, so instead test for it and only

56

use if it is available.

60

Reset 'blocking' flag after I/O wait

61

If the 'vnc_connection_read_wire' goes into an I/O wait

62

due to blocking I/O, the 'blocking' flag gets set to

63

true. Upon returning from the wait, it jumps back to

64

the start of the function, but does not reset the 'blocking'

65

flag to false. If the I/O attempt succeeds, this doesn't

66

matter, but if it fails for an error reason, this gets

67

mistakenly treated as blocking I/O again.

68

69

This is seen most often when the remote server drops the

70

connection. If the client was blocking on I/O at this

71

time, it could get into a potentially infinite loop.

76

77

Only trigger grab sequence upon release

78

GTK-VNC uses the keyboard shortcut ctrl+alt to toggle inside/outside

79

the VM (aka release pointer). Now Gnome uses ctrl+alt+arrow_key to

80

switch virtual desktops. So these two shortcuts collide and gtk-vnc

81

will grab the key presses as soon as ctrl+alt is pressed and toogle

82

inside/outside the VM, which makes switching desktops impossible.

83

84

The solution is to only trigger the grab sequence when the user

85

releases the key. So if they press Ctrl+alt and then release it,

86

we trigger, but if they press Ctrl+alt+left-arrow we don't trigger

92

Make handling of ZRLE encoding more efficient

93

Avoid memmove() on the uncompressed data buffer when dealing

94

with ZRLE encoding. Instead just track what offset we've read

95

upto.

99

Free coroutine stack when releasing coroutine

100

The coroutine_init function mmap's a stack for the

101

ucontext coroutine, but nothing ever munmaps it.

102

103

Abort if mmap of coroutine stack fails

104

If we fail to mmap the stack, abort the processs rather

105

than returning an error. This is standard practice in

106

glib apps, and the caller was not checking the

107

coroutine_init() return code leading to memory corruption.

111

connection: timeout connect() after 10s

112

It can take a minute or so before the connect() fails. Add an explicit

113

shorter timeout of 10s.

131

132

Update for 0.5.2 release

133

134

Delete browser plugin

135

The plugin code has been unmaintained for years and almost

136

certainly has security problems. A pure HTML5 solution like

137

noVNC is a far better approach to browser support for VNC.

138

139

Update RPM specs for F19 changes

140

141

Add perl example to RPM spec

142

143

Add python example using introspection

144

145

Add vnc_grab_sequence_get_nth

146

To allow introspected bindings to get access to keysyms, add

147

a vnc_grab_sequence_get_nth method

148

149

Rename gvncviewer.py to gvncviewer-bindings.py

150

151

Convert VncConnectionCredential to VncDisplayCredential

152

When forwarding the auth signal from VncConnection to consumers

153

of VncDisplay, the VncConnectionCredential enums must be turned

154

into VncDisplayCredential enums

155

156

2013-01-31 Daniel P. Berrange <berrange@redhat.com>

157

158

Fix conditionals in gvncviewer example

159

160

Auto-generate AUTHORS file from GIT logs

161

Rather than trying to manually keep track of authors,

162

just auto-generate the list from GIT logs

163

164

Add missing 'default' case to switch statement

165

166

Disable deprecation warnings

167

Glib deprecated GValueArray in favour of GArry

168

169

gvncviewer.c:450:9: warning: ‘g_value_array_get_nth’ is deprecated (declared at /usr/include/glib-2.0/gobject/gvaluearray.h:65): Use 'g_array_index' instead [-Wdeprecated-declarations]

170

171

Unfortunately these types are not ABI compatible. eg

172

compare the field orders

173

174

struct GValueArray {

175

guint n_values;

176

GValue *values;

177

};

178

179

vs

180

181

struct GArray {

182

gchar *data;

183

guint len;

184

};

185

186

So the replacement can't be used without a change in API

187

and ABI. This is unacceptable, so the deprecation warniings

188

must be disabled :-(

189

190

Avoid crash with unsupported audio formats

191

Currently if the VNC server sends an unsupported audio format,

192

we skip creating the pulse audio instance. When we later receive

193

audio data from QEMU we crash on this NULL instance. Instead we

194

should simply discard the audio data. Also log a warning if we

195

get a format we can't supported

2013-01-31 Cole Robinson <crobinso@redhat.com>

200

201

Fix enabling pulseaudio bits in gvncviewer

202

The gvncviewer.c file used a HAVE_PULSEAUDIO conditional,

203

but this was only defined for make and not in config.h

204

205

Add introspection annotation for vnc_display_send_keys

206

The vnc_display_send_keys method signature is too complex

207

to be interpreted correctly without some annotations.

2012-12-07 Daniel P. Berrange <berrange@redhat.com>

212

213

Avoid use of uninitialized variables in password echo prompt

214

215

Remove bogus check for 'conn' being null in vnc_connection_is_open

216

217

Fix size check on available write buffer space

218

The vnc_connection_write() function did not consider the current

219

write offset when calculating how much space was available in

220

the write buffer. This could lead to an array overrun.

221

222

Avoid array overrun setting up blt24 function

223

If a VNC colourmap mode was enabled, we would attempt to access

224

beyond the end of the blt24 function table. There are no blt

225

functions that can work for this mode, so just stub out the

226

array with NULL, and add a later check for NULL.

227

228

Fix missing check for OOM in python binding by s/malloc/g_new0/

229

230

Fix NULL dereference in debug logging on socket read error

231

232

Replace strncpy with memcpy in VNC password code

233

Using strncpy for the VNC key makes coverity worried about

234

unterminated strings. Switch to use memcpy to keep it

235

happier

To improve UNIX domain socket support, add the ability to open

296

a GSocketAddress instance. Pass the 'hostname' with the addr

297

298

another method for opening a FD which accepts a hostname, again

299

for SASL/TLS hostname verification when using a tunnelled

build: allow building with newer glibc-headers and -O0

322

Commit log and autoconf snippet written by Eric Blake for libvirt.

323

324

glibc 2.15 (on Fedora 17) coupled with explicit disabling of

325

optimization during development dies a painful death:

326

327

In file included from /usr/include/limits.h:27:0,

328

from /usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/limits.h:169,.

329

from /usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/syslimits.h:7,

330

from /usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/limits.h:34,

331

from util/bitmap.c:26:

332

/usr/include/features.h:314:4: error: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Werror=cpp]

333

cc1: all warnings being treated as errors

334

335

Work around this by only conditionally defining _FORTIFY_SOURCE,

336

in the case where glibc can actually use it. The trick is using

337

AH_VERBATIM instead of AC_DEFINE.

338

339

Avoid some deprecation warnings from GTK3 about device grabs

367

Temporary workaround to avoid deprecation warnings from GTK3

More fixing for gir generation

501

502

503

Fix GIR generation

504

Overriding PKG_CONFIG_PATH when generating GtkVnc-2.0.gir is

505

wrong since this means that if glib/... is installed in a prefix that

506

is not one of the default pkg-config paths, then it won't be found.

507

PKG_CONFIG_PATH is overridden so that g-ir-scanner can find GVnc-1.0.gir

508

in the build tree. Since g-ir-scanner provides --include-uninstalled

509

for that purpose, use that instead.

551

emacs magic to files which were missing it. Reindent all

552

files with new rules

553

554

Batch up incoming audio samples for upto 100ms

555

The length of samples received from the guest can be very

556

small (as little as 1 sample). If this is dispatched directly

557

to the audio sink this can cause excessive CPU consumption

558

and context switching. Batch up incoming data for upto 100ms

559

until dispatching it

560

561

Convert connection over to use audio objects

562

570

data packets

571

572

Remove all audio APIs from VncDisplay since we expose the connection

573

574

no need to duplicate all the audio APIs & signals in the VncDisplay

575

class

576

Introduce a basic impl of audio handler

595

Introduce a basic implementation of the audio handler which

596

emits a signal for each method. This enables apps to support

597

audio playback without needing to create subclasses. It also

598

isolates subclasses from extensions in the interface

Introduce a basic data type for audio samples

613

To avoid having to pass around all the parameters individually,

614

introduce a boxed data type for audio samples

615

616

* src/Makefile.am, src/libgvnc_sym.version,

617

738

739

Fix missing OS-X keymapping for letter 'A'

740

The keymap-gen.pl script was not correctly distinguishing

741

keycodes with a value of '0', from undefined keycodes. All

742

were skipped. This meant that the mapping for OS-X ANSI_A

743

key was lost (since it has value 0).

744

745

For similar reasons the XQuartz mapping for the letter A

746

was also lost.

747

748

* src/keymap-gen.pl: Fix handling of 0 vs undef for keycodes

749

* src/keymaps.csv: Remove bogus 0x0 entry in OS-X keymap

2011-01-28 Daniel P. Berrange <berrange@redhat.com>

765

766

Make pointer warp check more robust

767

The pointer warp code checks whether the local cursor

768

is hitting a boundary == 0, ==width, or ==height. This

769

is slightly too strict, it should check <= 0, >= width

770

or >= height

771

772

* src/vncdisplay.c: Make boundary check more robust

773

774

Fix warning about unused 'dpy' variable in keymap code

775

In GTK2 paths, GDK_IS_*_DISPLAY(dpy) evaluated to '1'

776

which meant 'dpy' could be unused. Change it to eval

777

to 'dpy == dpy' to trick compiler into thinking the

778

variable is in use.

779

780

* src/vncdisplaykeymap.c: Fix warning of unused variable

781

787

788

Fix setup of 'shared flag' when opening connection

789

The VncDisplay class forgot to pass the 'shared flag' onto

790

the VncConnection class when establishing a connection

791

792

2011-01-13 Daniel P. Berrange <berrange@redhat.com>

793

794

Refactor keymap handling to cope with multiple GDK backends

795

In GTK3 it is possible to have multiple GDK backends present.

796

The vncdisplaykeymap code needs a minor refactoring to cope

797

with this enhancement. The refactoring also trivially maintains

798

GTK2 compat

799

800

2011-01-05 Akom Chotiphantawanon <knight2000@gmail.com>

801

802

Added Thai translation.

803

804

2010-12-14 Daniel P. Berrange <berrange@redhat.com>

805

806

Fix leak of GSource objects which causes performance problems

807

The GLib event loop scales poorly as the number of GSource objects

808

increases. A missing unref on the GSource objects used in the VNC

809

connection meant that many unused instances accumulated, slowing

810

down the event loop processing.

811

812

* src/vncconnection.c: Unref all GSource objects

813

814

2010-12-09 Daniel P. Berrange <berrange@redhat.com>

815

816

Adapt to avoid further Gtk3 changes

817

More gdk_drawable calls have gone away in Gtk3. Adapt code to avoid

818

needing to use them, by calling gtk_widget APIs instead.

819

820

2010-11-29 Daniel P. Berrange <berrange@redhat.com>

821

822

Re-introduce a server side Pixmap to cache framebuffer

823

Despite use of clipping during drawing, rendering directly

824

from the client side cairo image, to the window incurred

825

a serious performance penalty for some users' X servers.

826

Re-introduce a server side copy of the VNC desktop using

827

a cairo surface, backed by an X Pixmap. This uses cairo

828

APIs directly, avoiding any need for GdkPixmap.

829

830

Remove check for Text::CSV

831

Revert the check for Text::CSV added in

832

833

753ddcb203fd9ad26829a065fd4d47c82773e849

834

835

Since the keymap files are now included in EXTRA_DIST, there

836

is no requirement fo Text::CSV at end user build time. Only

837

maintainers required the Text::CSV file when generating a

838

new dist.

839

840

2010-11-29 Daniel P. Berrange <dan@berrange.com>

841

842

Fix framebuffer update boundary check

843

Framebuffer boundary checks need to take into account offset,

844

in addition to width/height

845

846

* src/vncconnection.c: Fix boundary check

847

848

Avoid crash in TLS cleanup code on shutdown

849

The gnutls_bye() method may try to send data on the socket todo

850

graceful TLS shutdown. The priv->sock variable is possibly

851

already NULL at this point if the close was triggered via the

852

vnc_connection_shutdown() method. Change the latter so that

853

it only calls g_socket_close, not actually free'ing the

854

priv->sock object immediately. Also put sanity check code in

855

the TLS push/pull functions to catch future bugs in this area

856

857

Distribute built keymap files

858

Avoid the need for end users to have the Perl Text::CSV module

859

installed, by including the pre-generated keymap source files

860

in the dist.

861

862

* gtk-vnc.spec.in: Remove dep on perl(Text::CSV)

863

* src/Makefile.am: Include keymaps in dist

864

865

Avoid crash in motion event & vnc_display_get_pixbuf

866

If a mouse event occurs before a connection completes setup

867

priv->fb will be NULL and a crash can occur. Likewise if

868

vnc_display_get_pixbuf() is called before priv->fb is set,

869

then a crash occurs. Add checks for NULL in both cases

870

871

884

Fix data type of arg to cut-text signal in VncConnection

885

The vnc-server-cut-text signal is marshalled by

886

887

g_cclosure_marshal_VOID__STRING

888

889

so its argument must be a 'const char *', not a 'GString *'

890

datatype.

906

Enable building of a sub-RPM for gtk3

907

Allow a single RPM to build both gtk2 and gtk3 libraries

908

909

* gtk-vnc.spec.in: Add gtk-vnc2 sub-RPM for gtk3 binaries

910

911

Cope with building against newer gobject-introspection

912

Newer gobject-introspection wants --symbol-prefix and

913

--identifier-prefix instead of --strip-prefix. Test

914

for such a version and use the new style options if

915

appropriate

916

917

* configure.ac: Check for new gobject introspection

918

* src/Makefile.am: Adapt to g-ir-scanner flags

919

920

Fix rendering artifacts when running in scaling mode

921

The expose region was not large enough when running in scaling mode

922

resulting in horizontal & vertical line artifacts when moving

923

windows around on the virtual desktop. The previous fix used in

924

Gtk2 was not sufficient for Gtk3, so change the fix to be entirely

925

within the on_framebuffer_update handler

926

927

* src/vncdisplay.c: Hack to fix rendering artifacts

928

929

Add compat macro for GDK_DISPLAY

930

The GDK_DISPLAY macro is removed in Gtk3, add a compatibility

931

macro to allow build with Gtk2 and Gtk3

932

933

* src/vncdisplaykeymap.c: Add GDK_DISPLAY compat

934

935

Add compatability code for GDK symbolic keys

936

The GDK key macros were changed from GDK_ to GDK_KEY_ in GTK3.

937

Add some compatibility #ifdefs to allow the same macros to be

938

used on both Gtk2 and Gtk3.

939

940

* examples/gvncviewer.c: Add GDK_KEY compat

941

* src/vncdisplaykeymap.c: Add GDK_KEY compat

942

943

2010-10-27 Daniel P. Berrange <berrange@redhat.com>

944

945

Refactor drawing code to allow compatibility with Gtk3

946

In Gtk3, the expose_event is replaced with a 'draw' callback.

947

This is provided with a 'cairo_t' context that is already

948

configured with the clip region.

949

950

Split the current expose_event into two parts, the first

951

which creates a cairo_t based on the GdkEventExpose data,

952

and the second method which draws to that cairo_t. The

953

expose_event is conditionally disabled for Gtk3 builds,

954

just leaving the draw method which works on Gtk2 and Gtk3

955

956

* src/vncdisplay.c: Pull drawing code out of expose_event

957

method and disable expose_event on Gtk3

958

959

Remove the server side framebuffer cached in GdkPixmap

960

For rendering efficiency a GdkPixmap was kept on the server

961

duplicating what was in the old GdkImage object on the client

962

side. The client was changed to use a cairo image surface.

963

This can easily be rendered straight to the window and does

964

not appear to have any performance degradation. Thus the

965

GdkPixmap can be eliminated, avoiding the extra memory usage

966

that entails

967

968

* src/vncdisplay.c: Remove the GdkPixmap copy of the framebuffer

969

970

Change cursor to use GDK_BLANK_CURSOR instead of a GdkPixmap

971

The GdkPixmap class has been removed in GTK3. Since Gtk 2.16

972

there is a standard GDK_BLANK_CURSOR which can replace their

973

usage and works across Gtk 2 and 3.

974

975

* src/vncdisplay.c: Use GDK_BLANK_CURSOR

976

977

2010-10-25 Daniel P. Berrange <berrange@redhat.com>

978

979

Clear out more fields when closing a vnc connection

980

Be more paranoid about reseting internal fields when closing

981

a VNC connection, to prevent surprises when reconnecting

982

983

* src/vncconnection.c: Clear out more fields when closing

984

a connection

985

986

Add strict bounds checking on framebuffer updates

987

Some broken VNC servers send frame buffer updates which stray

988

outside the boundary of the desktop. This will lead to memory

989

corruption when rendering, so explicitly check for this and

990

drop the VNC connection.

991

992

* src/vncconnection.c: Add framebuffer update bounds checking

993

994

2010-10-21 Michal Novotny <minovotn@redhat.com>

995

996

Introduce vnc_util_get_version() functions to get version

997

this is the patch to allow user to get the GTK-VNC version using the

998

vnc_util_get_version() and vnc_util_get_version_string() functions.

999

Both the functions returns the version numbers based on the VERSION

1000

definition as created by autotools. Also, in version 2 (previous

1001

version) a new function called vnc_util_check_version() has been added

1002

to check whether the version of gtk-vnc is equal or higher to version

1003

requested. Function vnc_util_check_version() is defined as:

gboolean vnc_util_check_version(gint major, gint minor, gint micro);

1006

1007

The version of gtk-vnc is written in a "major.minor.micro" format

1008

and since the version number didn't change once the package was

1009

compiled version 3 is using VERSION_{MAJOR,MINOR,MICRO} constants

1010

being parsed and set by configure itself rather then parsing it

1011

at run-time.

1012

1013

Then there are 2 version functions. The difference between those

1014

functions is that vnc_util_get_version() returns the gint value

1015

based on bit flags that have to be converted to get the version

1016

number in the string format. It's designed for further processing of

1017

the major, minor and release versions.

1018

1019

If you want to get the version number only (e.g. to let the user

1020

know the GTK-VNC version he/she is using) you can use the second

1021

function called the vnc_util_get_version_string() which returns

1022

the string representation, e.g. 0.4.1.

1023

1024

For the vnc_util_get_version() function the gint is being returned

1025

with setting up appropriate bits. You can get the versions using

1026

following formula:

1027

1028

ver = vnc_util_get_version();

1029

major = (ver >> 24) & 0xff;

1030

minor = (ver >> 16) & 0xff;

1031

micro = (ver >> 8 ) & 0xff;

1032

1033

I think this patch could be useful for mainly for reason mentioned

1034

above. To check whether the user has at least 0.4.1 version of

1035

gtk-vnc using the vnc_util_check_version(0, 4, 1) is preferred.

1036

The vnc_util_get_version() function is a low-level function that

1037

could be useful to get the version number to be converted further.

Don't close the socket before the coroutine shut down

1042

The connection shutdown needs the socket intact:

1043

1044

7 0xb6d38cdf in vnc_connection_tls_push (transport=0x8d84108, data=0x8df33c0, len=229) at vncconnection.c:942

1045

1046

9 0xb6b2d12c in _gnutls_send_int () from /usr/lib/libgnutls.so.26

1047

10 0xb6b4d682 in gnutls_alert_send () from /usr/lib/libgnutls.so.26

12 0xb6d3a620 in vnc_connection_close (conn=0x8d84108) at vncconnection.c:4323

1050

1051

so close the socket after the coroutine shutdown. Otherwise it fills the

1052

console with:

1053

1178

Rewrite keymap code to work on more platforms

1179

The current keymap code assumes an Xorg server on Linux with

1180

either evdev or kbd drivers. This adds heuristics to detect

1181

XQuartz (Xorg on OS-X) and XWin (Xorg on Cygwin). Further it

1182

adds support for native GDK on OS-X and Win32.

1183

1184

It is not possible to assume that keycodes < 87 have a 1-1

1185

mapping to RFB (XT) keycodes. Thus the keymap arrays must

1186

have a complete dataset, all special casing is removed.

1187

1188

All master keymaps are defined in a CSV file. THis covers

1189

Linux keycodes, OSX keycodes, AT set1, 2 & 3, XT keycodes,

1190

the XT encoding used by the Linux KBD driver, USB keycodes,

1191

Win32 keycodes, the XT encoding used by Xorg on Cygwin,

1192

the XT encoding used by Xorg on Linux with kbd driver.

1193

1194

Further RFB and final Xorg driver mappings are derived

1195

from these master maps automatically. The keymap-gen.pl

1196

tool can generate lookup tables between all possible

1197

keycode sets as required.

1198

1199

eg To generate a map from native Win32 keycodes to RFB

1200

2010-07-20 Daniel P. Berrange <dan@berrange.com>

1215

1216

Disable extended key events if keymap is unknown

1217

Currently if we cannot determine the GDK keymap, we default to

1218

the XT keymap. This is not a good choice because is causes

1219

definite breakage on several platforms. If the keymap cannot

1220

be determined, it is safer to disable the extended key event

1221

support completely & rely on traditional VNC keysyms.

1222

1223

Also rename the x2pc methods to be gdk2rfb, since that's what

1224

the conversion is actually doing.

1225

1226

Change way encodings are disabled at runtime

1227

The approach for disabling pseudo encodings is fragile because

1228

it relies on ordering in the array. Rewrite to allow removing

arbitrary encodings

1231

1236

GIO provides GSocket and GResolver classes that can replace all

1239

gnulib for socket portability

Use separate soname when building against GTK-3

1265

The GTK-3 library is not ABI compatible with GTK-2. Thus when

1266

GTK-VNC builds against GTK-3 it is not ABI compatible with a

1267

build done against GTK-2. It is thus neccessasry to allow for

1268

parallel install of GTK-2 and GTK-3 builds. This is done by

1269

changing the library name, pkgconfig name and include file

1270

locations

1271

1272

GTK-2:

1273

1274

libgtk-vnc-1.0.so

1275

gtk-vnc-1.0.pc

1276

1281
