TCP streaming problem
I have a TCP streams app which needs to receive relatively large amounts of data (600k) through a slow connection (modem or cellphone). Most of the time it works, but sometimes the stream seems to slow down to a complete halt and timeout. I've tried increasing the receive timeout from 25 to 50 to 120 seconds, but it only makes things worse because it takes longer for my app to realise something is wrong. The server end is a windows server, and at the server end a timeout also occurs - it's as if the network has stopped. The interesting thing is that when you re-try the data transfer it starts off fine, then slows down and eventually times out again. Has anyone had similar experiences with NetLib? Is there some limit I've hit?

Why new [] works in Debug but not Release (was: Allocating memory for C++ objects)
>I have a call to "new wchar_t[blah]". In debug build, it works
fine in a find launch code. In the release build, it crashes
>And crashing on the otherwise entirely trivial line:
wchar_t* newBufferW = new wchar_t[newLength+SIZEOFNULL];
>SIZEOFNULL is a Class static const int, not a define.
CodeWarrior is smart enough to turn a static const int into a define (inline
it), so that was not the problem. Thanks CodeWarrior.
In case anyone else can learn from my wasting most of a day reading maps and
looking at assembly code, here is the solution.
I am using CodWarrior 9.2
In a POL release build, the new [] operator, aka, __nwa__FUl, was getting
inlined right into my .cpp file.
So far, not a problem. But In a completely different file, I am using
"#pragma segment Segment2" and new [].
Codewarrior included new there also and the linker decided that was the One
True version of new.
As far as I can tell, if you use a inline function in multiple segments via
"#pragma segment", and that function uses a standard C++ library call like
memcpy or new, those library calls could be linked into any segment you are
using them in. Apparently it's random?
End result: new [] (__nwa__FUl) gets put in Segment2.
I can't use "Merge Compiler Glue into Segment 1" because my first segment is
so tight. I can't fit anything more into it. I need a way to force the
linker to put __nwa__FUl in the first segment. My solution was to make sure
any function using new is put in the first segment via #pragma segment.
Now here's some more fun - #pragma has an interesting "quirk".
If I have a function
#pragma segment Segment1
void Foo()
{
int a = new int[5];
}
#pragma segment Segment2
The new [] will get linked into Segment2, not Segment1 as you (ok, I) might
expect. You have to put the "#pragma segment Segment2" after the NEXT
function.
It would have saved me a hell of a lot of time if I'd figured out what the
symbol for new [] was (__nwa__FUl). I saw "__construct_new_array" in my
first segment and figured I was good.

Bug with WinCopyRectangle on Palm IIIc
My application performs a stylus-controlled map pan by moving most of the screen window using WinCopyRectangle in winPaint mode. Things work fine except on a Palm IIIc (real device or POSE, with debug/non-debug ROM), where panning downward or rightward often crashes with the following error message: Application just read from memory location 0x1EFE, causing a bus error.

Re: Multipleline Text Field
I think, I found an answer (originally posted by Darren Beck in the group pilot.programmer): Darren proposed the following: 1) Get the handle to the field's text (FldGetTextHandle) 2) Lock the handle to get a pointer to the text 3) Use the pointer and change the text however you want it 4) Use FldFreeMemory to release all memory the field has. 5) Use FldSetTextHandle to link the handle to the field again. 6) Unlock the handle again. I did it in a slightly more complicated way, which works also (i.e. for multiline fields): 1) Get the handle to the fields text 2) Lock the handle to get a text pointer to the old text of the field. 3) Create a new handle for your new text (MemHandleNew) 4) Lock the new handle to receive a text pointer for your new text. 5) Copy the new text to the new text pointer (StrCopy) 6) Use FldFreeMemory to release the old field's memory completely 7) Unlock the new handle 8) Use FldSetTextHandle with the new handle to set the new text for the field. The field's attribute "single line" must be deactivated for a mutliline view, of course. And you should call FldDrawField after both recipes above, otherwise you might not see the change of the text. This worked for me, at least. Hope it helps. Marcel.

The most likely reason for your problem is that the author is mistaken. Look at your library with "m68k-palmos-ar tv libfoo.a". If you see dozens of small .o files, corresponding more or less to the separate functions in the library, then the linker in prc-tools-m68k will be able to pull in only the .o files it needs and your executable will not become bloated with functions you are not using. If you see only one monolithic .o file, then the author does not know how to build a Unix-style static library. > So the REAL problem I am having is that the compiler is including ALL the > library instead of just the pieces I am actually referencing/using. Perhaps > I have settings of the linker so that it is not properly discarding unused > library code? In Code Warrior, a library is really just an object file. CW uses an object file format in which functions and function-static data and so on are stored in separate hunks within the object file. It is this arrange- ment into separate per-function hunks that allows CW's linker to strip unused functions and their data from inside an object file. To the GNU linker, as on Unix for decades, a library is a collection of object files. If several functions are in one object file, then they are all smooched together into the same sections. They are not separable. The linker used in prc-tools-m68k DOES NOT DISCARD UNUSED FUNCTIONS. Rather, it only pulls an object file in from a library if that object file provides a function (or a symbol) required to satisfy the link. The atomic unit is an object file, not a function [1]. Once an object file has been pulled in, any unused functions in that object file cannot be discarded, because there is no way to separate them from the other functions in the object file. Thus a badly built monolithic linker library causes the bloating effects you are seeing. The GNU linker does in fact support similar behaviour to CW on some platforms. A combination of GCC's -ffunction-sections flag and the linker's --gc-sections produces an explosion of separate sections that provide similar capabilities to CW's object format's hunks. But these flags are not supported on prc-tools-m68k at this time. > 1) Is there a way to specify which functions in a library go into which > segments (remember, all I have is the .h and .a file; it isn't my library)? > If I modify the .h file with the SECTION_X postfix, will that work? As noted in the documentation and in the archives many many times, the SECTION_X annotation needs to be visible (in particular) when the function to which it refers is compiled. If you annotate the .h file but do not recompile the .a archive, this will obviously not hold. No, that will not work. > 2) Is there way to force the compiler to evaluate which functions are > actually used BEFORE it stakes out space for them in the codres so that it > will not consider unused ones?

Re: One directional IR transmission without connection
I tried it with the Serial Manager Functions, and it works fine. The Serial Manager provides functions to access the IR port without any protocol support and enables the programmer to do really low-level things with it. I think I will go on in this direction.

If it is a proper library, then that is exactly what the linker will do. It seems that for some reason the whole library is pulled in. If you link with -Wl,--verbose you can see which modules are extracted from lib.a. Also the link map contains this information. Then you will have to figure out why it pulls in everything. Some things which might help: Look at the symbol definitions with nm: 'm68k-palmos-nm -s ' If there is no library index, create one with 'm68k-palmos-ranlib '.

Re: Alarms not always triggered
It happens to me too. I have an app that uses alarm but some of my users report that the alarms never get triggered. It's not a device specific problem because I tested the app on multiple "clean" device (nothing but the app installed) and it works perfect. Anyone can offer an idea of what is causing the problem? Help will be very much appreciated. Thank you York Kie From: James Screech Date: Thu, 15 Aug 2002 03:53:52 My application uses an alarm to perform an operation at a specific time, most of the time this works fine (even with the Palmswitched off). However if some applications are active (PalmOS clock) the alarm is never triggered and with others (Today) the alarm is triggered only after the application is exited.

GCC: Force 3rd party library into 2 different segments?

OK, now that you've had your fun (which is somewhat deserved), hopefully you are willling to help me actually figure out WHY this does nothing for me. I started out in the beginning using it in the link phase and it did nothing. I tried -t, -T, linker, compiler, EVERYTHING. Nothing works. I am trying to add a 4K library to my primary code segment. That's it. It won't fit in the default 32K segment but doubling that is WAY more than enough so that's what I want/need to do. And yet when I do exactly what you have so derisively described, it makes no difference. Not only that, the linker/compiler NEVER give any errors at all. As I said before, I can do "-t garbage", "-T garbage" and get nothing to let me know that it is even there. So I have no feedback as to where I might be off track. All I know is I am desperate to get this in and I can't do it and there doesn't seem to be any example anywhere online of this in use. Armed with the map file I can see that indeed, it is now (and actually probably was in the beginning) creating a large(r) coderes segment as evidenced by these 2 differences: coderes 0x 0x8002 coderes 0x 0xfcd0 The reason I assumed it *wasn't* working was because I get the classic "coderes is full" error when linking in the FourKLib library. The library itself is actually 23080 bytes but the author told me that this gets trimmed by the linker (for my type of use) to about 4K (I am only using 3 functions out of the 40 or so). So the REAL problem I am having is that the compiler is including ALL the library instead of just the pieces I am actually referencing/using. Perhaps I have settings of the linker so that it is not properly discarding unused library code? Evidently what the linker does is allocate space for ALL the functions in an included library FIRST and then strips out the actual code after the fact. Therefore I need to be able to fit the entire 23+K into the codres even though only 4K or so will end up there. So the questions I now have are: 1) Is there a way to specify which functions in a library go into which segments (remember, all I have is the .h and .a file; it isn't my library)? If I modify the .h file with the SECTION_X postfix, will that work? This would seem like my best bet. 2) Is there way to force the compiler to evaluate which functions are actually used BEFORE it stakes out space for them in the codres so that it will not consider unused ones? -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

Tealscript crashes
Hello,
recently we encountered strange crashes of our app. All of them appeared
only when Tealscript was enabled. (TS is a kind of hack offering improved
character recognition. It does so by replacing some system traps.)
Very strange thing is that the crashes can be more-or-less safely reproduced
after TS is activated. Once we pass certain crash, it cannot be reproduced
(unless TS is switched off/on), but the other crashes (usually) work (until
they happen the first time). This points to an initialization problem in the
Tealscript.
Here is a typical sequence:
TS activated.
Our app launched, a dialog with an edit box opened.
Writing 1 letter on the graffiti -> crash.
During the text editing we run our own event loop, where we process some
special events. (Such as eg. scrolling when keyDownEvent for vchrPageDown
appears.)
Another typical crash happens when the Find button is pressed while the
progress dialog is running. The logic of the progress dialog is as follows:
During lenghty processing we periodically call HandleEvents(10), which runs
the event queue with a single purpose: to test whether the user issued an
abort signal. Just for the illustration here is the relevant code:
static Boolean g_bHas5way = false ;
Boolean TestAppStopEvent( EventType *event )
{
if( g_bHas5way && event->eType == keyDownEvent &&
vtKeydownIsVirtual( event) )
if( event->data.keyDown.keyCode & navBitSelect )
if( event->data.keyDown.modifiers & autoRepeatKeyMask )
{
EventType ev ;
ev.eType = appStopEvent ;
EvtAddEventToQueue( &ev );
return true ;
}
return false ;
}
static void HandleEvents( int count )
{
EventType event;
while( count-- && EvtEventAvail() )
{
EvtGetEvent(&event, 1);
if( event.eType != nilEvent )
{
if( TestAppStopEvent( &event) )
{
g_abort = true;
break ;
}
if(! SysHandleEvent(&event) && g_progressActive )
FrmDispatchEvent(&event);
if( event.eType == appStopEvent )
{
EvtAddEventToQueue( &event );
g_abort = true;
break;
}
}
}
}
One user reports a crash after our app exits. (Again, only when TS is
active.)
The last thing: After I did some (seemingly unrelated) changes and after a
hard reset (forced by some calculator), my crashes disappeared, whereas the
user experiences his crashes further on.
I have no idea what to do and the Tealscript guys are not interested either.
(Although I would bet that the problem is on their side.)
Can anybody give me some advice?

StrCat, pointer reinitialization, bug in CW v9.0?
Hi,
I have a similar code developing in CW v9.0 like the following (simplified) :
static Boolean SatLogFormHandleEvent( EventPtr event )
{
char *filename;
char temp[5];
...
...
switch ( event->eType )
...
...
case ctlSelectEvent:
filename=0;
filename=NULL;
filename="";
...
/* put the year, month, day, hour, minute, second after *filename
using StrCat*/
...
StrCat(filename,temp);
...
/*the complete filename*/
}
When I debug my code with CW v9.0 IDE, the first selection of this event
has no problem, a right filename is displayed in the debug window of CW and
a label in a form. However, the second selection of the same event has a
problem as follow:
the line: filename=0;CW debug window shows filename is a
"invalid pointer " , which is right.
the line: filename=NULL; CW debug window shows filename is a "invalid
pointer " , which is right.
the line: filename=""; CW debug window shows filename is the same
as the complete filename of previous file, which is wrong,
and *filename= '0' (it was *filename='/' in the first run)
Why the second run of the above event restores the same filename of the
first run even after reinitialization? Would it be the problem of using
StrCat() or handling and freeing memory of pointer? Or, would it be a bug
of CW v9?
Anyone knows why and how to fix this problem.
Many thanks.
