Especially for the introduction of the Queue method the internal Synchronize handling was modified. Instead of handling only one event there is now a queue of events which is walked completely when CheckSynchronize is called. Each entry in the queue can carry a PRTLEvent which will be signaled when the contained method has been executed and thus Synchronize methods can still be blocking.
Exceptions inside the queued methods are either handed back to the calling method for Synchronize events or raised directly (after leaving the queue in a valid state) to the caller of CheckSynchronize.
The way platform specific adjustments can be made to TThread was changed. Instead of implementing the Constructor and Destructor directly one now implements the methods SysCreate and SysDestroy which are called from the Constructor and Destructor respectively. All RTLs were adjusted for this and should be controlled by the platform maintainers for correct compilation (Unix works).
The new method NameThreadForDebugging has two overloaded variants: one with the thread name as AnsiString and one with the thread name as UnicodeString.
By default the AnsiString variant calls the UnicodeString variant and the latter needs to be implemented. This can be changed by defining THREADNAME_IS_ANSISTRING for a platform. Then the UnicodeString variant calls the AnsiString one and the AnsiString one needs to be implemented.
Also added was a global property CPUCount for the System unit. This property returns the number of virtual cores of the system.
New methods and functions that should be implemented per platform are:
System.GetCPUCount (default returns 1)
Classes.TThread.GetSystemTimes (default zeros the struct)
Classes.TThread.NameThreadForDebugging (default does nothing)
More detailed information about the added methods will be available in the feature announcement mail.

o support for the new codepage-aware ansistrings in the jvm branch
o empty ansistrings are now always represented by a nil pointer rather than
by an empty string, because an empty string also has a code page which
can confuse code (although this will make ansistrings harder to use
in Java code)
o more string helpers code shared between the general and jvm rtl
o support for indexbyte/word in the jvm rtl (warning: first parameter
is an open array rather than an untyped parameter there, so
indexchar(pcharvar^,10,0) will be equivalent to
indexchar[pcharvar^],10,0) there, which is different from what is
intended; changing it to an untyped parameter wouldn't help though)
o default() support is not yet complete
o calling fpcres is currently broken due to limitations in
sysutils.executeprocess() regarding handling unix quoting and
the compiler using the same command lines for scripts and directly
calling external programs
o compiling the Java compiler currently requires adding ALLOW_WARNINGS=1
to the make command line

unicodestring = java.lang.String. The reason this was the default in
the past is that this was the first string type that was implemented,
and without it being the default most code involving string operations
would fail. Now the default strings types are the same as for other
targets
+ new {$modeswitch unicodestrings} directive, that when activated
*together* with {$h+},
1) changes char into an alias for widechar
2) changes string into an alias for unicodestring
3) changes the preferred string evaluation type (in case of uncertainty)
to unicodestring
{$modeswitch unicodestrings} with {$h-} does not change anything at all
regarding the string type (it still changes the char type)
+ new uuchar unit that redefines char as widechar, and which is automatically
included by the compiler if {$modeswitch unicodestrings} is enabled

change in utils/fpcm/fpcmake.ini in prevous commit.
Adapt also other files to that change:
* compiler/globals.pas: Replace $FPCTARGET by os_string if
tf_use_8_3 flag is set for target_info also.
* tests/Makefile.fpc: Modify TEST_TARGETSUFFIX in the same way
as TARGETSUFFIX was modified in previous commit.
* tests/utils/dotest.pp:
+ New variable UseOSOnly, set to true if only target OS name
should be used for subdirectories.

later: the same as i386/darwin, except
a) uses the non-fragile Objective-C ABI/runtime
b) does not require stubs for direct calls/jumps (not required for
i386/darwin under 10.6 and later either, but still generated
there for backwards compatibility)
c) only the same packages are enabled as for ARM/Darwin
d) MacOSAll is compiled specifically for the iPhoneSimulator SDK
This target also defines the symbol "darwin" apart from the target
name "iphonesim" for source code compatibility reasons.

* An attempt to optimize forced screen updates in video mode, because they really blow, and Free Vision forces a whole screen update on every window move
* Probably other stuff i already forgot
git-svn-id: trunk@12799 -
initialisation code, because that's a typed constant already initialised
to that value and it interferes with a generic solution to set islibrary
to true for libraries
git-svn-id: trunk@12376 -
* removed tons of Win32 unit leftovers, and other cleanups
* cursor handling fixes, additions (like changing cursor shapes)
* added initial support for sysmsgs

because -1 is a valid argument for this function there.
This bug is also in the original AmigaOS C SDK, which specifies
this argument as ULONG, and defines -1 as valid argument for it.
git-svn-id: trunk@11981 -
* less debug during init
* SysGetShiftState() support, reworked RawKeyCode support
* support for more keys, with qualifiers. for example some clipboard operations work now in FV.
git-svn-id: trunk@11973 -
+ now properly sets ScreenColor to true
+ optimized DrawChar() to use BltTemplate() instead of WritePixel() loops
this results in less gfx operations, major speedup, and elimination of
possible display trashing (WritePixel() doesn't wait for blit operations
to finish)
+ updated vgafont in videodata.inc to be in proper format for BltTemplate()
+ other tweaks here and there
