coblongpamor · 2012-04-01 13:30:40

dear every body

i just compile and run the MainDemo sample under delphi 7 and win 7 ultimate.
then i just create new record then error occured like screenshoot below:

i don't know why. can any one help?

thanks.

Try update your sqlite3*.obj, Armand updated sqlite engine some days ago.

coblongpamor · 2012-04-01 16:33:41

@Junior/RO:
I've done it. This bug has been there since version 1.15.
I had already been posted in this forum, and I'll have to wait for another user who will report it too, but until now no one did.
I think this only happens on my computer.
I do not know, what information is required from my computer to be able to overcome this problem, while I have not been able to use TSynLog.

I ever use madExcept. if it is indeed useful, I will try to use it, and report back here.

I've compiled the main demo in Delphi 7 under Windows 7 (this is my main dev platform), and there is no problem.

You may have some deprecated files around in your search path.

I can't access to the screenshot (corporate firewall policy).

Could you step into the debugger and find the Delphi source code line which fails running when compiled with Delphi 2009?

You can also compile TestSQL3.dpr regression test, enabling the logs in SQLite3SelfTests.pas:

procedure SQLite3ConsoleTests;
begin
  AllocConsole;
  // will create around 280 MB of log file, if executed
  if TRUE then // this will ENABLE LOGs
  with TSQLLog.Family do begin
    Level := LOG_VERBOSE;
  ....

Then extract and post here the block where the GPF occurs.

heare is the result when i run TestSQL3.Dpr with Logs Enabled.

You may have some deprecated files around in your search path.

my path hierarchy of the mORMot framework is

..\mORMot
		\SQLite3
		\Sample
				...
				\MainDemo
				...
		\LVCL
		\SynProject

and the search path of MainDemo Project is:

..\..\..\Lib\FastMM496\FastMM
..\..\SQLite3
..\..

thank again

coblongpamor · 2012-04-02 08:17:09

@TLama
But, i think, this is not the same issue.

ab · 2012-04-02 08:37:55

You seem to have the latest source code and .obj available, and your search path seems correct.

Sounds like a configuration issue to the named pipe access policy, when compiled with Delphi 2009.

It is very strange that it fails first, then that all tests passed later on.

It sounds like http://synopse.info/forum/viewtopic.php?id=177 which occurred in some configurations.

It is a random issue, which did not occur for me.

Could you try the changed set at http://synopse.info/forum/viewtopic.php?pid=996#p996
That is, put "nil" instead of security attributes:

 aPipe := CreateNamedPipe(pointer(fPipeName),
      PIPE_ACCESS_DUPLEX,
      PIPE_TYPE_BYTE or PIPE_READMODE_BYTE or PIPE_WAIT,
      PIPE_UNLIMITED_INSTANCES, 0, 0, 0, nil{@fPipeSecurityAttributes});

But there is something strange in the security handling of Windows for named pipes.

ab · 2012-04-02 09:24:57

Where is the AV triggered?

From your test logs, you have included the latest .obj files (3.7.11).

coblongpamor · 2012-04-02 10:17:25

i have change the @fPipeSecurityAttributes to nil, then run Test again, and all test passed.
then i set back @fPipeSecurityAttributes, then run test again, and all test passed.
i do that, more than one time.

then i open and run the MainDemo Project, then i try to edit record, then AV accured again,
without break on any line, just show the CPU process. pressing F9 key not help.

then i disable the

{.$define EXTRACTALLRESOURCES}

in FileMain.pas with compiled sucses.
but if i run the project, immediately EOSError class occured with message:

System Error. Code: 12029

and debuger break on end of procedure TWinHTTP.InternalSendRequest(..) in the SynCrtSock unit.

procedure TWinHTTP.InternalSendRequest(const aData: TSockData);
var L: integer;
begin
  L := length(aData);
  if not WinHttpSendRequest(fRequest, nil, 0, pointer(aData), L, L, 0) or
     not WinHttpReceiveResponse(fRequest,nil) then
    RaiseLastOSError;
end;

then i enabled it back

{$define EXTRACTALLRESOURCES}

and i error occored while compiling with message

Undeclared identifier: 'ExtractAllResources'

i've downloaded the latest version of SQLite3i18n unit.

ab · 2012-04-02 11:20:37

You have to BUILD the project, not only COMPILE it, when you change a global conditional.

In case of an AV, close the CPU view, then press F7 or view the call stack. You'll find out why line made the error.

coblongpamor · 2012-04-02 11:47:17

i understand and i did it, but error as described above still happen;

In case of an AV, close the CPU view, then press F7 or view the call stack. You'll find out why line made the error.

Now, I can not run maindemo.dpr, because the error that occurred at the beginning, just as I described above.

I'll try to run another project.

ab · 2012-04-02 12:42:05

Did you try defining PUREPASCAL in Synopse.inc or in your project Options conditional defines?

coblongpamor · 2012-04-02 13:46:37

No. PUREPASCAL Conditional Define still still disable in synopse.inc.

ab · 2012-04-02 13:48:10

So please try with PUREPASCAL conditional enabled for the whole project.

coblongpamor · 2012-04-02 14:01:21

Yes, i also tried to enabling

{$define PUREPASCAL}

as you suggest.
but

System Error. Code 12029

still occured.

ab · 2012-04-02 14:26:41

"System Error. Code 12029" sounds like a firewall issue for me.

You do not have the HTTP server working as expected.

is this because of antivirus? i use avg antivirus, i'll try to disable it.

But,
I just downloaded again all the files in the folder maindemo of the source code repository.
I put it in a new folder named maindemo1.
and the system error code 12029 does not appear anymore.
i just run, and then close immediately, not yet create a new data.

coblongpamor · 2012-04-02 16:19:32

I just tried to add a new record on maindemo I just downloaded, there is no error message appears.
but the grid displays strange characters like this.

strange characters

then immediately I tried to add a new record again, and system error appears as follows:

system error. code 12002

and stop here, after pressing Ok button.

TWinHTTP.InternalSendRequest procedure (const ADATA: TSockData);
var L: integer;
begin
   L: = length (Adata);
   if not WinHttpSendRequest (fRequest, nil, 0, pointer (ADATA), L, L, 0) or
      not WinHttpReceiveResponse (fRequest, nil) then
     RaiseLastOSError;
end; //line break here

pressing the F8 key, arriving on this line (line 3810) in SynCrtSock

InternalCloseRequest;

I press and hold the F8 key, until the AV like this

debugger fault notification

pressing the F7, F8, F9, Shift + F7, Shift + F8, AV appears again and again.
so I press the Ctrl + F2.

ab · 2012-04-03 06:10:48

I'm still unable to see your pictures (proxy blocking policy).

About code 12002, this is a HTTP Client-Server error (something like Server not responding).
So there is something wrong with your HTTP connection.

There is a problem with the current implementation of the grid display, when you have one or two rows only within.
I'll fix it ASAP.

while you improve the implementation of the grid view, please check it thoroughly.
because, when I test, the error does not only occur in one or two records, but sometimes it can be more than 2 records.
Also deleting record without a check mark, the data still appear, but if we press the refresh button.

deleting one or more record with check mark is still problematic.

thank you.

ab · 2012-04-06 11:54:35

I've identified and fixed an issue of unhandled buffer in TSQLTableJSON.UpdateFrom().
This was the cause of unexpected characters in grid display, which may occur randomly (even with more than 2 records).
See http://synopse.info/fossil/info/fc65a0c9a2

I've also fixed the UI refresh issues on deletion.
See http://synopse.info/fossil/info/4c881e5bce

coblongpamor · 2012-04-06 16:29:27

thank you. i'll try it.

coblongpamor · 2012-04-07 00:07:24

so far, the AV and the odd character has not appeared again.
Thank you.

ab · 2012-04-07 07:19:56

Good news.

I'm happy it helps.

coblongpamor · 2012-04-07 08:36:00

. i'm more happy than you about it.
thank you for this wonderful framework, and keep it open source. I'm obsessed with this framework, but UI is an important issue for me. although you have to include it, but it takes time for me to learn. slowly and with your support is very good, I'm sure I could master it later.
and of course I believe this framework will be more perfect

thank you....

Today failed to run TestSQL3, MainDemo also not working, TestSQL3 exception information is as follows:

ab · 2014-07-15 19:20:08

We were not able to reproduce the problem.

Both TestSQL3 and MainDemo works as expected on our side.

Are you sure your .obj are the latest available from http://synopse.info/files/sqlite3obj.7z ? Are you not mixing sources or obj?
Could you find out what's wrong? What is the call stack when the exception is triggered on your side? Which version of Delphi are you using?
