The inseparable changes necessary to support live color updating across the
system in a sane, safe, and performant manner.
BView gains:
HasSystemColors()
HasDefaultColors()
AdoptSystemColors()
AdoptParentColors()
AdoptViewColor(BView*)
SetViewUIColor(color_which, float tint)
SetHighUIColor(...
SetLowUIColor(...
ViewUIColor(float* tint)
HighUIColor(...
LowUIColor(...
DelayedInvalidate()
BWindow gains a simple helper method:
IsOffscreenWindow()
BMessage gains:
AddColor()
FindColor()
GetColor()
HasColor() * allegedly this API is deprecated, but I implemented it anyway
ReplaceColor()
SetColor()
Previous private ColorTools methods are made public and moved into GraphicsDefs:
mix_color, blend_color, disable_color
These are fully compatible with BeOS dan0 R5.1 methods and are just code cleanup
of BeOS example code under the OpenTracker license.
In addition, four new colors are created:
B_LINK_TEXT_COLOR
B_LINK_HOVER_COLOR
B_LINK_ACTIVE_COLOR
B_LINK_VISITED_COLOR
These changes are documented in their proper user documentation files.
In addition, due to a history rewrite, B_FOLLOW_LEFT_TOP has been defined and
used in lieu of B_FOLLOW_TOP | B_FOLLOW_LEFT and is included in this commit.
On the app_server side, the following has changed:
Add DelayedMessage - a system by which messages can be sent at a scheduled time,
and can also be merged according to set rules. A single thread is used to service the
message queue and multiple recipients can be set for each message.
Desktop gains the ability to add message ports to a DelayedMessage so that
said messages can target either all applications or all windows, as needed.
Desktop maintains a BMessage which is used to queue up all pending color changes
and the delayed messaging system is used to enact these changes after a short
period of time has passed. This prevents abuse and allows the system to merge
repeated set_ui_color events into one event for client applications, improving
performance drastically.
In addition, B_COLORS_UPDATED is sent to the BApplication, which forwards the message
to each BWindow. This is done to improve performance over having the app_server
independently informing each window.
Decorator changes are live now, which required some reworking.

* Changed the way the attributes are written to make sure that everything
that can be written once is in fact written just once.
* The rename code in BMailProtocol::_ProcessFetchedHeader() was broken,
and caused the hang of the last commit.
* This was never implemented and no one noticed until now.
* A default value for a pointer doesn't make that much sense anyway, so
using the FindPointer method is fine.
No functional change intended.
Focused on documented classes only.
* Update copyright information.
* whitespace fixes.
* pointer style
* Rename some variables, msg => message, form => what
* Need consistent variable names to make documentation easier,
allows us to use \copydoc or \copydetails instead of repeating
ourselves over and over again.
fixed size flag at once. Not sure if this can be merged into one of the
existing GetInfo() variants without breaking binary compatibility.

in BMessages. Also added type codes for them in TypeConstants.h. Closes ticket
#6302. Thanks!

Net_server starts services by invoking fork() followed by exec(). If the latter
fails (for instance because the service isn't installed), the forked child is
invoking exit(). This in turn unloads libbe, triggering static cleanup code in
BMessage, which deletes a couple of message ports that were inherited from the
parent during the fork. After that, net_server was desparately missing those
ports and no longer worked reliably.
* in InitTerminateLibBe, we now register an atfork-(child-)handler, which
takes care to re-initialize the static reply ports used by BMessage code
* added BMessage::Private::StaticReInitForkedChild wrapper and
BMessage::_StaticReInitForkedChild() implementation which overwrites the
inherited port IDs with a set of own ports

storage.
* Remove reduntant information from the header (field_count vs. fields_size).
* Remove checksums previously used to validate the message passing by area
mechanism.
* Move variables that are purely used by the instance out of the header and into
the BMessage object.
* Use more sensible types for the different message fields.
* Reduce some field sizes to realistic values.
* Make size_t values into uint32 values so the message format will not change
when later moving to 64 bits.
* Pack the structures used for flat message storage so it doesn't change
because of padding.
* Fix message passing by area. It never worked because the created area was
never actually filled with any data!
* Some more allocation checks with graceful fallbacks (should be all now).
* Some more checks for negative index values (should also be all now).
* Make printing more inline with how the rest of the class works and make some
of the output more consistent.
* Also add the new unsigned types to PrintToStream() output.
* Fix printing of unknown types and invalid BMessages, it would always have
printed only the first entry respectively the same error.
* Added some clarifying comments.
* Cleanup.

bool return type. Did I mention this was an unstable Haiku extension?

the data of two BMessages and allows recursive comparison (BMessage inside
BMessage). Note that using this API might require you to recompile your app in
the path to R1.

the new sematic of transfer_area so a message area is transfered into the right
teams' address space and it does not need to be cloned there anymore. Passing
by area is only used for messages bigger than a certain size (currently
hardcoded to 40KB) which should be somehow bound to the max port message size.
This makes passing large messages (i.e. > the port limit) possible, so for
example copy&paste of long text, image data, etc. should now work.
Got rid of the fClonedArea member as it is not necessary with the new design,
renamed shared_area to message_area in the private message_header, avoid
an unnecessary allocation of the header for the copy constructors, check
allocations in a few more places and some minor cleanup.

BDirectory without declaring it first. Since that's an actual bug, I made the
changes in the Haiku headers, and copied them back to the build headers.

with PostMessage() in case the message queue is full.
Some notes:
* for synchronous replies, we don't use this mechanism yet, but it could be
extended to do that as well.
* the code looks so complicated because we need a way to access the looper's
queue without locking it (to prevent deadlocks); like Dano's solution, I've
abused BTokenSpace to store a BDirectMessageTarget with a BHandler.
* we also need to decouple the lifetime of a looper's queue from its target,
as we cannot lock the looper, and therefore, can't guarantee it stays valid
as long as we're accessing it outside of BLooper.
* init_clipboard() now needs to be done after the global constructors have
been called - since sending messages now needs gDefaultTokens to be initialized.
Since this is done per image, it shouldn't cause any troubles, though.
* some minor cleanup, removed unused _msg_cache_cleanup_() and friends.

This will allow to fix message related problems like drag and drop and scripting.

task_looper() again.
* removed BMessenger::fPreferred - whenever you had to specify "usePreferred" separately,
you don't have to do that anymore - use B_PREFERRED_TOKEN instead.
* fixed BTokenSpace::GetToken() semantics: it will no longer touch the "object" argument
in case of failure.
* Introduced a BWindow::_DistributeMessage() that will be part of the event dispatcher
counterpart to the app_server (the other will be _DetermineTarget()).
* Made it easier to use Michael's Message4 implementation: just add the following line
to your UserBuildConfig:
AppendToConfigVar DEFINES : HAIKU_TOP src : USING_MESSAGE4 : global ;
* Introduced ServerWindow::HandlerMessenger() and FocusMessenger() - the first will
target the client handler, while the other will target the preferred handler of the
client looper (usually the view having focus).
* Fixed dano message unflattening in the Message4 code.
* Changed BMessage::PrintToStream() to no longer use macros in the Message4 implementation.
* I hope that's all - it's a huge change, but it's all connected.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@15046 a95241bf-73f2-0310-859d-f6bbb57e9c96
cleanup.
* made BMessageQueue::IsLocked() const - the non-const version is still provided
for binary compatibility.
* Both BMessageQueue::FindMessage() versions are now thread safe, the queue's BLocker
is now mutable to allow for this.
* renamed BMessage::link to fQueueLink as the "Message4" implementation uses it.

categories:
* Missing includes (like <stdlib.h> and <string.h>).
* Linking against $(TARGET_LIBSTDC++) instead of libstdc++.r4.so.
* Local variables shadowing parameters.
* Default parameters in function definitions (as opposed to function
declarations).
* All C++ stuff (nothrow, map, set, vector, min, max,...) must be imported
explicitly from the std:: namespace now.
* "new (sometype)[...]" must read "new sometype[...]", even if sometype is
something like "const char *".
* __FUNCTION__ is no longer a string literal (but a string expression), i.e.
'printf(__FUNCTION__ ": ...\n")' is invalid code.
* A type cast results in a non-lvalue. E.g. "(char *)buffer += bytes"
is an invalid expression.
* "friend class SomeClass" only works when SomeClass is known before.
Otherwise the an inner class with that name is considered as friend.
gcc 4 is much pickier about scopes.
* gcc 4 is generally stricter with respect to type conversions in C.

a separate class. This allowed to improve _SendFlattenedMessage() to
deal properly with flattened BMessages as well.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11116 a95241bf-73f2-0310-859d-f6bbb57e9c96
proper private static BMessage members and made them accessible through
BMessage::Private. Got rid of unused _reconstruct_message_().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11106 a95241bf-73f2-0310-859d-f6bbb57e9c96
a buffer is given.
* Added method for sending flattened messages. The KMessage support is
complete, but for BMessages this is a bit tricky. We currently unflatten
the BMessages and send those.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11060 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added calls to _init_message_(), _delete_message_(), and
_msg_cache_cleanup() to InitTerminateLibBe.cpp
Finished first implementation of BMessage::SendReply(), BMessage::_send_(),
and BMessage::_send_message()
Add BMessage to app.src, removed BBlockCache from support.src.
New BMessage::Private class has functions for twiddling BMessage internals
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4371 a95241bf-73f2-0310-859d-f6bbb57e9c96
adding entry_refs and BMessages. Lots of stuff for specifiers and also for
sending replies (with thanks to Mike Nordell).
