Lazarus 1.6 broke my app

[BeniBela]

After compiling my app with Lazarus 1.6/fpc 3 rather than a year(s) old trunk, it does not work on my phone anymore!

It just gets stuck at

and then it waits forever and does not get anywhere.

What is going on? Is it stuck on the first initialization section?

[marcov]

Doesn't say much, except the clock monotonic seems to suggest it is stuck in a loop with gettickcount or some other loop with time checking.

He knows he has to put in a reproducable example in code. He gave up on doing that. Bit of a sorry state he's in 
Maybe we should help him?

This is not so easy to run anything on this crap Android phone.

My USB cable is broken, so I load the things on it using adb-over-network.

On friday I tried doing it, but suddenly it stopped working. Then I noticed I could not access the internet anymore even on my laptop. ADB must have send invalid packages that crashed my entire wifi router.

Today I have been installing things, then the phone turned off and suddenly the phone power key stopped working. I could not start it anymore and had to reboot it.

Afterwards  adb  got stuck on installing, because I had changed the partitions to be readonly and forgot to remount it as rw after the reboot, so it could not install anything.

[BeniBela]

So it loads the .so. And the imports except libdl:

Code: [Select]

Now gdb (on my laptop) is frozen and does not react anymore on anything.

But I got a stack trace.

But all the address in the pas are outside the code. Before the first begin or on  the last.

Give sourcecode, not stacktraces. I am not prepared to reverse engineer. I am prepared to replicate or refute issues with sourcecode and I have plenty of time for that.

[BeniBela]

The source does not really matter.

Now I removed everything and it freezes the same:

Code: [Select]

library simplelcl;

{$mode objfpc}{$H+}

{$DEFINE UseCThreads}

uses
{$IFDEF UNIX}{$IFDEF UseCThreads}
cthreads,
{$ENDIF}{$ENDIF}
Interfaces,
jni;



function JNI_OnLoad(vm: PJavaVM; reserved: pointer): jint; {$ifdef mswindows}stdcall;{$else}cdecl;{$endif}
begin
  result := JNI_VERSION_1_4;
end;

procedure JNI_OnUnload(vm: PJavaVM; reserved: pointer); {$ifdef mswindows}stdcall;{$else}cdecl;{$endif}
begin
end;

exports
  JNI_OnLoad name 'JNI_OnLoad',
  JNI_OnUnload name 'JNI_OnUnload';

begin

end.

Even the stack dump is the same, except for the addresses inside the so

[Thaddy]

Since when doesn't sourcecode matter to find bugs nobody can replicate? and plz add initc to the uses clause. (First)

[BeniBela]

That changes nothing

But we are getting somewhere. It is the interfaces unit.

This works

Code: [Select]

library simplelcl;
{$mode objfpc}{$H+}
uses initc;
begin
end.

This fails

Code: [Select]

library simplelcl;
{$mode objfpc}{$H+}
uses initc,interfaces;
begin
end.


[BeniBela]

This also fails

Code: [Select]

library simplelcl;
uses cwstring;
begin
end.

And interfaces pulls in cwstring (interfaces -> InterfaceBase -> LazUTF8 ->  cwstring). (which also brings your initc)

And what can cwstring be reduced to?

Code: [Select]

library simplelcl;
uses dl;
begin
  dlopen('libicuuc.so',RTLD_LAZY);
end.

which also fails.

You were right, the code actually mattered

Perhaps Android cannot load a library during the initialization of another library

Have you tried build and use trunk version of FPC? It seems that this bug is fixed in it : http://svn.freepascal.org/cgi-bin/viewvc.cgi?view=revision&revision=34406

No, I only checked if there was a relevant change in cwstring

You could have said something, before I wasted my weekend on this. 


I wonder, if that issue has a known fix, too: https://github.com/benibela/xidel/issues/2#issuecomment-230065399

[BeniBela]

Is there no option to just disable cwstring? I do not need it, I have my own unicode functions

[yuriy_sydorov]

BeniBela, the trunk version of FPC has a lot of bug fixes and improvements for Android.
