Memory Leak in ExtPascal / Linux / Apache / MOD_FASTCGI

[Frank Menne]

Hi !

I have a weird problem with Extpascal:

I Took Lazarus 0.9.30, current Ubuntu Linux, Apache 2.2.16,
MOD_FASTCGI 2.4.6, Current Firefox as frontend.

Compiled the current SVN Trunk with current examples and startet then
without debugger.

On each request which comes from the apache (for example Show source -
Button) memory of the Extpascal backend process increases by 2 MB.

This also happens in current stable Version 0.9.8.

Now I tried that with Lazarus / Windows, there I do not have any
Memory - Problems. No extra memory consumption per request.

Tried to play a little with
FCGIAPP.C, line 626
{$IFNDEF MSWINDOWS}EndThread(0){$ENDIF} // Unix RTL FPC bug

currently with no effect.

Hi Frank,

 

Tried to play a little with
FCGIAPP.C, line 626
{$IFNDEF MSWINDOWS}EndThread(0){$ENDIF} // Unix RTL FPC bug

currently with no effect.

You removed that line?

See line ~244 too:

change 

  {$IFDEF MSWINDOWS}inherited;{$ENDIF} // Collateral effect of Unix RTL FPC bug

by

  inherited;

Fixed half of the memory leak:

At the end of
TFCGIThread.Execute;

if fsession.NewThread=false then
freeonterminate:=true;

instead of the EndThread(0);

After that modification all Helper Threads without own session run
into the Destroy-Procedure after termination. No Access Violation -
that works.

In the ExtPascalSamples I reduced the memory leak from
348 bytes / Request to 188 bytes / Request.

Correction: Problem seemt to be gone with the above change. Will try a
24 - hours burn in test.. ;-)
