Corrupt database

From my test one of my table is corrupt.

When I try to use:

 
DBTabellaClienti := Database.ExecuteList([], query);

to retrieve TSQLTableJSON I have some problem. The first time the TSQLTableJSON is ok but if I try to retrive it again from a client I have all black records or records with strange characters.
From my test with a new database I don't have this problem, so I think my database is corrupt.

I'd like export data from old database and import it inside the new database. Is there a way to make a dump (sql text format) to export the data and then import it? Or in alternative a way to export the data (all database or single table) as CSV and then import it?

In fact I don't think I can repair my database.

Re: Corrupt database

Try to execute a VACUUM command on the database (e.g. using our SynDBExplorer or any other SQLite3 editor).

See http://sqlite.org/lang_vacuum.html

If there is no "database corrupted" explicit warning, the database is not corrupted.
This is your client/server implementation which is not working as expected.
Without code to reproduce the problem (I do not speak of just some part of your code, but a code snippet easy to reproduce the issue), it is almost inpossible to find what is wrong.

Re: Corrupt database

I just have try VACUUM command but it not work.

I post here the code:

procedure TMainForm.AggiornaGrigliaClienti(Force: Boolean = False);

        end;

      btnContactEdit.Enabled := False;
      btnContactDelete.Enabled := False;
    end;
end;

The user can use the procedure to update the GUI (a NextGrid grid). This code works always the first time, but after the first time if I call it from the client I get the right number of records, but all records value are balck or with strange symbols (rarely). I never noticed this problem when I call the function from the server.
I use the same code also for other tables/grids and I don't have this problem.

Another information (but I think this is another problem, I don't know if you need of this), when I try to open a database (old or new) my application try to create a backup with this code:

      try
        Stream := TFileStream.Create(Folder + NewName + '.cbbak', fmCreate);
        try
          Stream.Seek(0, soFromBeginning);

          DatabaseServer.Backup(Stream);
        finally
          Stream.Free;
        end;
      except

        Exit;
      end;

From 1/2 week the backup file have size = 0 byte and I have this error: "cannot VACUUM - SQL statements in progress".

Re: Corrupt database

I have make some other test when I use the code:

      try
        Stream := TFileStream.Create(Folder + NewName + '.cbbak', fmCreate);
        try
          Stream.Seek(0, soFromBeginning);

          DatabaseServer.Backup(Stream);
        finally
          Stream.Free;
        end;
      except

        Exit;
      end;

I get alsway this error: "cannot VACUUM - SQL statements in progress". Any ideas?

Do you have find any problem on my code of post #3 about possible database corrupt?

Re: Corrupt database

VACUUM is working as expected - it is made several times in the regression tests.
See e.g. TTestSQLite3Engine._TSQLTableJSON

But perhaps some statements are still opened in your code.
Is it the case?

Or perhaps it is stopping because of some prepared statements in the background.

Could you try adding a fStatementCache.ReleaseAllDBStatements; call in the Backup method BEFORE the vacuum:

function TSQLRestServerDB.Backup(Dest: TStream): boolean;
var Source: TFileStream;
    Closed: boolean;
begin
  result := false;
  if (Self=nil) or (DB=nil) then
    exit;
  DB.Lock(''); // flush internal cache
  try
  try
    // VACUUM will fail if there are one or more active SQL statements
    fStatementCache.ReleaseAllDBStatements;
    // perform a VACCUM to recreate the database content
    DB.Execute('VACUUM');
    Closed := false;
    try
      Closed := sqlite3_close(DB.DB)=SQLITE_OK;
      // compress the database content file
      Source := TFileStream.Create(DB.FileName,fmOpenRead or fmShareDenyNone);
      try
        Dest.CopyFrom(Source,0);  // Count=0 for whole stream copy
        result := true;
      finally
        Source.Free;
      end;
    finally
      if Closed then begin
        DB.DBOpen; // reopen the database if was previously closed
        InitializeEngine; // register functions and modules
      end;
    end;
  finally
    DB.UnLock;
  end;
  except
    on E: Exception do
      result := false;
  end;
end;

Re: Corrupt database

In this moment I'm not on my office so I cannot make the test. I will do it later and then I will report the result.

In any case as you can see from post #3 the object DBTabellaClienti is not destroy. I use DBTabellaClienti and other table with UpdateFromServer, so if I destroy it I cannot use UpdateFromServer. Is this a problem?

DBTabellaClienti is create the first time when the database is open (before backup) and then is destroy when the database is closed. Until the databse is open I reuse DBTabellaClienti to know if I need update the GUI.

If this is a problem is there an alternative way?

Re: Corrupt database

There is no DB statement in a TSQLTableJSON content: only some JSON buffer and pointers to the data.
So a living DBTabellaClienti should not hurt, IMHO...

Re: Corrupt database

I have make a test, if I use this code:

Database := TSQLRestClientDB.Create(Model, nil, Filename, TSQLRestServerDBWithService, False);

I can backup my database without problem, but if I use this code:

Database := TSQLRestClientDB.Create(Model, nil, Filename, TSQLRestServerDBWithService, TRUE);

(aHandleUserAuthentication = TRUE), when I try to make the backup I have this error: "cannot VACUUM - SQL statements in progress". Any idea?

Besides do you have some ideas about my problem of post #3 about the possible table/database problem or curruption?

Thanks

OK thanks, I will wait fot it.

I last think. I hope the last before release the beta version of my software, I continue to have problems with Database.UpdateFromServer for one of my table (see first code of post #3).

I have make a test, I hope this can help you to help me smile

1) Run Server and Client application;
2) Open the database and call an update GUI function, see AggiornaGrigliaClienti(Force: Boolean = False); both on server and client, all is ok. NOTE I have do a small edit of AggiornaGrigliaClienti, I use DBTabellaClienti.GetJSONValues(True); to save the DBTabellaClienti as text file. In this case I have a small file, about both on server and client computers;
3) I edit the table (on server or client), for example I change a text value field for a record (a small change);
4) Call again AggiornaGrigliaClienti both on server and client to update the GUI;
5) Result on server = right result, the GUI is update and the text files is about 96 KB (in fact I have make small change), result on client = bad result, DBTabellaClienti have the right number of rows but all records have a black value for all field, besides my text file is over 100000 KB!!! I have open the text file, there is a BIG JSON text...

I use a similar procedure with other 5 grids (same update code, only the sql is different), but I don't have this problem.

Any ideas?

Re: Corrupt database

Two issues fixed:
- fixed VACUUM failure if there are one or more active SQL statements
- fixed potential GPF in TDynArrayHashed.ReHash after TDynArray.Clear call

Re: Corrupt database

I've fixed TSQLRequest.Execute(JSON: TStream) method in SynSQLite3.pas.

It now allows field names at least, even with no data (as expected by TSQLRestClientURI.UpdateFromServer).

Re: Corrupt database

Ensure that you got the latest version from http://synopse.info/fossil

I've made some other fixes since the one related above.

Re: Corrupt database

From my test now VACUUM works but I have always the same problem with one of my table (contacts), please see post #3.

Any suggestions on what to do? I'm going crazy.

Re: Corrupt database

I think you are talking about the grid issue.
See http://synopse.info/forum/viewtopic.php?pid=3926#p3926

I'm working on fixing it.

Re: Corrupt database

Do you think is the same problem?
On my code I don't use official tdrawgrid function because I don't use a tdrawgrid on my application. I retrive the table then I update my grid (nextgrid)...

However, I hope you're right and that fix bug smile

Re: Corrupt database

I've identified and fixed an issue of unhandled buffer in TSQLTableJSON.UpdateFrom().

This was the cause of unexpected characters in TSQLTableJSON array.
