[s2; Design decisions and trade`-offs&]
|
||||
[s0;i150;b33;O0; At the moment, we strongly favor static linking
|
||||
of U`+`+ packages. If nothing else, it makes U`+`+ apps self`-contained
|
||||
(together with system of .lay and .iml files) and also much faster
|
||||
to load (and run) in Linux (just compare start times of UWord
|
||||
with some KDE based word`-processor). Shared builds were implemented
|
||||
mainly to improve build times in debug mode.&]
|
||||
[s0;i150;b33;O0; CPU has to be either little`-endian or big`-endian
|
||||
(exotic architectures are not supported), in flat 32`-bit mode
|
||||
or in 64`-bit mode with sizeof(int) >`= 4 (that is quite standard).
|
||||
Currently tested CPU architectures are i386, AMD64, ARM and PowerPC.&]
|
||||
[s0;i150;b33;O0; CPU and compiler are supposed to support [^topic`:`/`/Core`/srcdoc`/Moveable`$en`-us^ M
|
||||
oveable] (true for any gcc platform and MSVC`+`+ as well).&]
|
||||
[s0;i150;b33;O0; We decided to ignore possibility of `"out`-of`-memory`"
|
||||
exceptions and recovery. If U`+`+ application goes out of memory,
|
||||
it simply prints the error message and terminates. This is quite
|
||||
pragmatic resolution `- our experience is that it is quite hard
|
||||
and annoying to achieve robustness here and it cannot be reliably
|
||||
tested. Also, most platforms with virtual memory will almost
|
||||
freeze long before out`-of`-memory problem due to intensive page
|
||||
swapping. Connected issue `- default and copy constructors are
|
||||
not allowed to throw exceptions in U`+`+ (the common reason to
|
||||
throw exception here was out`-of`-memory condition). This limitation
|
||||
will be removed in future releases.&]
|
||||
[s0;i150;b33;O0; Maximum number of elements in any of U`+`+ containers
|
||||
(including GUI elements, like number of rows in DropList) is
|
||||
2[` 31 ]`- 1 `= [%00-00 2,147,483,647.]&]
|
||||
[s0;i150;b33;O0; GUI is single threaded. That does not mean you cannot
|
||||
do multi`-threaded GUI apps `- just use only one thread to perform
|
||||
GUI and communicate with others via timer queue (We guess this
|
||||
method is far safer anyway).&]
|
||||
[s0;i150;b33;O0; U`+`+ does not use OS`-native widgets. The main
|
||||
reason for this is to achieve widget interface model optimal
|
||||
for rapid development. The less important reason is that this
|
||||
way it is much easier to make U`+`+ cross`-platform. On the other
|
||||
hand, Chameleon skinning system achieves native look`&feel, so
|
||||
there is a little perceivable difference for end user.&]
