I have observed this very same crash many times on ARM !
With various FPC versions and Lazarus versions. |
|
|
|
Exactly.
Second run works without crash.
Cleaning lib/$(CPU_TARGET)-$(OS_TARGET) also helps.
Looks like reading outdated PPU raises exception without proper error report or unit rebuild requirement. |

This looks fishy:

The debug message for entering "LeaveCriticalSection" comes right after the debug message for entering "EnterCriticalSection".
The actual call for FWorkerMessages.EnterCriticalSection has not happened yet.

I have an additional request for lazbuild.
Lazbuild has an option "--max-process-count"
If I understand the docs, the default is to max the process-count if undefined.
I would like to propose to use only a single process as default.
In the same way that make has a --jobs option: 1 per default.
To stretch this request even more ... ;-)
This is the Makefile patch I use for useride:
*****************************************************
useride:
ifdef LAZBUILDJOBS
ifdef LCL_PLATFORM
./lazbuild$(SRCEXEEXT) --max-process-count=$(LAZBUILDJOBS) --lazarusdir=. --build-ide= --ws=$(LCL_PLATFORM)
else
./lazbuild$(SRCEXEEXT) --max-process-count=$(LAZBUILDJOBS) --lazarusdir=. --build-ide=
endif
else
ifdef LCL_PLATFORM
./lazbuild$(SRCEXEEXT) --lazarusdir=. --build-ide= --ws=$(LCL_PLATFORM)
else
./lazbuild$(SRCEXEEXT) --lazarusdir=. --build-ide=
endif
endif
*****************************************************
starter:
As you can see, also the --ws is set !!
My 2 cents. |
|
|
|
@Alfred, does using only a single process cure the crash, too?
It is a reasonable suggestion in any case. |
|
|
|
Well. I am not sure.
All installs by fpcupdeluxe patch the Lazarus makefile as proposed above. I have not seen this error since then on my own systems and have not received any reports anymore regarding this crash by users.
But this is not a rocket-science conclusion as you will understand. |

> All installs by fpcupdeluxe patch the Lazarus makefile as proposed above.

Do you mean your code block would replace in the root Makefile this at line 3391?
useride:
./lazbuild$(SRCEXEEXT) --lazarusdir=. --build-ide=
The Makefile is actually generated from Makefile.fpc.
It has a comment on top saying :
# Don't edit, this file is generated by FPCMake Version 2.0.0
I had to study this topic when I recently split IdeIntf package.
So the patch should go to Makefile.fpc file. There starting at line 189 is :
#-----------------------------------------------------------------------------
# calls lazbuild to build lazarus and packages with user's settings
# requires lazbuild
# ignores LCL_PLATFORM and OPTS
useride:
./lazbuild$(SRCEXEEXT) --lazarusdir=. --build-ide=
It has an explicit mention about ignoring LCL_PLATFORM and OPTS. This must be asked from Mattias. He is the only one who knows the build details well.
One more thing: I don't find LAZBUILDJOBS anywhere in the Makefile. Is that correct?
And another: The Makefile section builds Lazarus useride using LazBuild. It does not build LazBuild itself, thus it cannot fix any bug in LazBuild.
What bug exactly gets fixed? I think we a mixing too many issues here now.
|
|
|
|
@juha.
Yes, the change must be made in Makefile.fpc. And, after the change, the Makefiles must be re-generated.
If Mattias is going to take a look at the Makefile, I would like to ask both of you to look at some other reports about the Makefile also. Perhaps you are to review these also.

Ps:
The latest release of fpcupdeluxe does not patch for LAZBUILDJOBS anymore.
The Makefile itself only gets an internal hack for the LCL_PLATFORM, otherwise using lazbuild on Darwin cocoa fails.
I have included the original patch for the Makefile, for your info.

"And another: The Makefile section builds Lazarus useride using LazBuild. It does not build LazBuild itself, thus it cannot fix any bug in LazBuild.

The above is 100% correct. I still have no real clue about the original crash report or its fixes. |
|
|
|
As I said, the patch forcing using only one process does reduce de occurrence rate, but still not fixing this issue. I continue seeing it in the continuous integration builds. |

Hello Juha and Abou,
In the process of making fpcupdeluxe multi-threaded, I have used the Lazarus code for external tools.
Code-re-use is always better than re-inventing the wheel.
While using the code, I encountered some crashes. I solved it by changing the destroy-sequence.
Look here:
destructor TExternalTools.Destroy;
begin
RunExternalTool:=nil;
TerminateAll;
EnterCriticalSection;
try
if fRunning.Count>0 then
raise Exception.Create('TExternalTools.Destroy some tools still running');
if ExternalToolList=Self then
ExternalToolList:=nil;
if ExternalTools=Self then
ExternalTools:=nil;
inherited Destroy; <----------------------------------------- In original code, destroy is called here.
FreeAndNil(fRunning);
FreeAndNil(fParsers);
finally
LeaveCriticalSection;
end;
DoneCriticalsection(FCritSec);
inherited Destroy; <----------------------------------------- In my code, destroy is called here. This solved all crashes.
end;
Please review. |
|
|
|
I just reviewed the above change myself: did not work.
So, never mind. Will keep on searching. |
|
|
|
Was close.
The below causes no crashes anymore !
destructor TExternalTools.Destroy;
begin
RunExternalTool:=nil;
TerminateAll;
EnterCriticalSection;
try
if fRunning.Count>0 then
raise Exception.Create('TExternalTools.Destroy some tools still running');
if ExternalToolList=Self then
ExternalToolList:=nil;
if ExternalTools<>Self then
inherited Destroy;
FreeAndNil(fRunning);
FreeAndNil(fParsers);
finally
LeaveCriticalSection;
end;
DoneCriticalsection(FCritSec);
if ExternalTools=Self then
inherited Destroy;
end; |
|
|
|
Alfred, can you please provide a patch. In related 0036959 you have a patch which looks different from your destructor TExternalTools.Destroy code here. Why? It was about the same problem, wasn't it?
|
|
|
|
Hi Juha,
Yes, please use the patch as attached in
https://bugs.freepascal.org/view.php?id=36959
It looks good to me, has logic, and prevents all crashes. |
|
|
|
Ok, the patch is similar. The other part sets FTool.FThread:=nil; without using the setter method.
However calling inherited Destroy from different places based on a global variable feels like a hack.
What more, having 2 global variables (ExternalToolList and ExternalTools) for the same purpose feels like a hack, too.
ExternalToolList is defined for the base class and it should be enough IMO.
How would you fix the bug if ExternalTools variable was removed?
I will send a question for the ExternalTool author Mattias, too.
|
|
|
|
Alright. I will (also) wait for Mattias answer too, before discussing this in detail. |
|
|
|
I added the make useride options LCL_PLATFORM and LAZBUILDJOBS to Makefile.fpc and Makefile in trunk |
|

Your patch calls inherited based on ExternalTools=Self. In lazbuild the ExternalTools is at that point already nil, so you never call inherited. Please confirm. |
|
|
|
Formerly ExternalTools was freed using FreeAndNil, which first sets ExternalTools to nil, and the calls Free.
I changed it to ExternalTools.Free, so ExternalTools is still set during the destructor, and the call of TerminateAll.
I was not able to reproduce the crash in lazbuild, so please test, if this makes a difference for you. |
|
|
|
First, thanks for the Makefile changes !
Second: no luck. Still crash.
Thanks to a previous (related) report, this crash is now easy to reproduce (on Windows) by compiling lazpaint with lazbuild. |
|
|
|
See my changes in r63079. It does not try to fix any crashes but it clarifies the global variables.
I turned ExternalTools from a global var into a global function, returning ExternalToolList.
Duplicate assignments to ExternalToolList was removed. Now ExternalToolList is assigned only in TExternalToolsBase constructor and destructor.
Please test.
So the change by Mattias made no difference. Please try if your earlier change "FTool.FThread:=nil;" does.
Otherwise I have no idea what is going on. |
|
|
|
Sorry about this, but its still not working.
Makes me curious: may I ask what is wrong with the patch I proposed, that results in a working lazbuild ? |

Please see note #c122412 by Mattias. Your patch prevents inherited Destroy ever being called, thus leaking memory. Mattias also asked for your confirmation in that note.
By looking at your patch I can say it is a hack. Something is seriously wrong if you must call inherited Destroy from 2 different places based on a global variable value.
I admit a memory leak is better than a crash but we should find the fundamental reason for the crash.

I added debug lines in r63082. There are many calls to CheckSynchronize by procedure TExternalToolsConsole.HandleMesages.
Please add more debug lines to suspicious places. I believe the actual bug can be tracked finally.
[Edit] I downloaded LazPaint sources from GitHub and tried to build it, as it allegedly triggers the error more often.
It cannot be built with the BGRA* stuff provided by OPM. Is it really so? Do I need to download the packages from somewhere else?
|
|
|
|
I tried lazbuild 63082 with -B -r dozen times on Win10 with fpc 3.0.4 32bit. Never a crash.
Instead of unreliable lineinfo stacktrace, can you get a gdb backtrace? |

Here you go.

This does not look like a gdb backtrace. See here:
https://wiki.lazarus.freepascal.org/Creating_a_Backtrace_with_GDB#Very_short_how-to |
|
|
|
There is a gdb stack trace at the issue description. Is is missing something? |
|

Alfred's patch in the related 0036959 effectively prevents calling inherited Destroy in TExternalTools.Destroy.
TExternalTools is a container of threads.
Why would it fix the SIGSEGV which happened much earlier when synchronizing individual TExternalTool threads.
I created a new patch against Lazarus trunk that only comments out the inherited Destroy, although it makes no sense.
Please test.
We would also need a fresh debugger stacktrace from Lazarus trunk. The line numbers in the original stacktrace do not match.

Hi Juha,
Without using your latest patch, I have tried to reproduce the error without success.
Using a script to use lazbuild to compile lazpaint for 50 times in a row caused no problems at all.
I am using FPC trunk and Lazarus trunk. Will keep trying to reproduce.
Edit:
After 72 runs, I got THE error again.
Will now try your patch.
|

I found a suspect where a freed Tools collection could affect:
procedure TExternalTool.WaitForExit;
It has inside a loop :
if MyTools.IndexOf(Self)<0 then exit;
However WaitForExit was not in the stacktrace. I increased Sleep() time there to 50ms. I don't know if it makes reproducing the bug easier or more difficult. You can try smaller values in your tests.
I have also added DebugLn() calls around.
|
|
|
|
Please test with r64005. See related 0037883.
|
|
|
|
Will do ! |
|
|
|
Testing done. Results of building lazpaint with lazbuild (as before).
With Sleep(1): not a single crash. Tested 100 times.
Without Sleep(1): 75 crashes out of 100 builds.
With ThreadSwitch: 70 crashes out of 100 builds.
Conclusions.
Sleep(1) solves all problems.
Its not only the context-switching of sleep() itself: The 1ms delay itself seems to be very important also.
So, please add Sleep(1), also in fixes. Thanks. |
|
|
|
Great!
Sorry what is ThreadSwitch exactly?
Do you know why Sleep(1) and the delay are important? I cannot figure out any reason. |
|
|
|
ThreadSwitch: https://www.freepascal.org/docs-html/rtl/system/threadswitch.html
I was just researching the possibility that only context switching was necessary. With little hope, due to the fact that it was reported that Sleep(0) did not work.
This is a LONG standing bug that has been solved by adding Sleep(1). I am happy with it.
The code for using multi-threaded external tools in "ideexterntoolintf.pas" is very complex. Its hard to understand the execution-flow of this code. I have no time to dive deep into it. And again, I am very happy with the fix that solves 3 years of random crashed (reported by many users of fpcupdeluxe) when using lazbuild. |

|
|
Now it is in fixes 2.0 branch, too.
Resolving finally ...
