Thank you for your regular developments! :)
I noticed that the Windows installer is not signed with a Code Signing Certificate.
Does the project or foundation need money e.g. for such external costs?
So far I have not seen an intensive appeal for donations. Are there any costs the community should participate in?

We can't find every problem, cause more often than not users think about code that we didn't think about. Though these users don't seem to have used trunk or the 3.2 fixes branch or RC1, cause SEH has been enabled for Win32 for some months now and in Win64 even for the whole lifetime of 3.0!

Also the second bug is a problem of the user (in this case the author of TProcessUTF8) not protecting their code against field reordering (though that had been improved (https://svn.freepascal.org/cgi-bin/viewvc.cgi?view=revision&root=lazarus&revision=61736) in Lazarus Trunk, but not merged back to 2.0.x).

Reverting to 2.0.8...

Yes, there's always "someone" to blame and that someone is always someone else, eh? Did you do any testing? Lodge any bug reports against trunk?

Post by: Birger52 on July 14, 2020, 12:42:34 pm

1. Seems the problem exists in 2.0.8 as well. Not with "fresh" component, but with existing ones - reuse or redesigning - even when previous anchors are removed.
2. I was not blaming anybody - just hate to fight the tools, rather than solving the problems I need solved. And I am not the one having released this version.
3. I am probably not qualified for testing. Out of date, one could say. And even if I was qualified, I do not have the time.

Definitely not intending to demeaning or criticize all the hard work done.

I am replying to this, but not about you. There are many with exactly that answer. "You" in the below, shall refer to all individuals who are unaware of the simplicity.

This is primarily about testing new Fpc, because they have a longer release cycle and that makes it more important.

It is trivial. And quick.

Well I haven't tested it on Linux/Mac. But it should be similar. https://wiki.lazarus.freepascal.org/Multiple_Lazarus#Linux

On Windows, it goes as follow
- Download the test installer that we provide (I made announcements for test builds with the new fpc, before it was released)
- Run it.
- Enter a new directory to install too (i.e. c:\laz_test\ )
- Check "secondary install"
- Next page enter a config dir (i.e. c:\laz_test\conf\ )
Done

- Packages:
Well, ok, if you have lots of packages installed, you need to redo that. That is the one point that may add some extra time. Depends how many of them you test.

- Publish projects:
From your original Lazarus, open your projects, and "Export" them to a new folder. (Project > Publish Project)

- Test:
Then open the published project in the 2ndary install. Compile and test it. Compile with -O1 -O2 -O3 and -O4 if you want (and can afford 3 or 4 minutes extra per project)

How long you think that takes?
If you have 2 or 3 projects, you should be done in under half on hour. (And compilation and download could be done in the background)

---
How much time, do you spent if you install the update (overwriting your current install), and then things crumble and do not work?

Of course if all your projects depend on 3rd party close-sourced packages that are not available for the test release, then indeed you cannot test your projects.

Title: Re: Lazarus Release 2.0.10
Post by: Birger52 on July 14, 2020, 09:23:31 pm

Understanding it's not really me you're talking to. ;)

First off, the things you outline here, does not seem to take much time. Tho, being retired, the mind does not spin all that fast - luckily, this does not affect the PC - only the typing speed, and other human aspects.

The main thing about "testing" to me, is actually about reporting the errors or malfunctions found - and I assume probably also a qualified guess, as to why things are NOT functioning - which is the main goal and the main time-consumer, in any form of testing.

I have a hard time checking that my own projects are working as they should - also when used in ways they were not intended to, or exposed to stuff they were not supposed to be exposed to.
Having to do it in several other environments, is not really appealing.

Best leave the guessing of the Why to the professionals who know the inner workings. Already knowing that something goes wrong is the most important part. And of course an explanation what one had done to trigger the problem (which is as important as knowing that something is erratic at all, cause a dev needs to be able to reproduce it to fix it).

Hello all. I think i've encountered a bug with 2.0.10 I've tried to install UECONTROLS from the online package manager but fails when tried to compile BCGRABITMAP.
I didnt have this problems with 2.0.8 or any previous version.
Other components installs fine (zeosdbo, lnet, uniqueinstance and a few more)
Previously i've uninstaled 2.0.8, and cleaned lazarus folder on appdata manually.
Im using windows 10 pro x64 1909 and installed lazarus 2.0.10 x86.
Downloading manually BCGRABITMAP and BCGRACONTROLS and tried to install them gives error on FFont.CharKerning function, appearently didn't recognize it

Thanks and keep good work and sorry for my bad english!

I'm working with previous version, 2.0.8, so I'll install 2.0.10 as a secondary installation and I'll try to compile my apps.

Thank you very much!!!

This is how I have a problem with TDateTimePicker and Lazarus 2.0.10. version i368-win32-win32/win64.
The problem is that when I put the value NULL on the TDateTimePicker property DATE, the project will not be translated-executed, as the error states "Error reading DateTimePicker1.Date: Floating point overflow"
While in Lazarus version 2.0.10 x86_64-win64-win32/win64 works fine.

You should have opened another thread for TDateTimePicker problem.

Anyway, NULL is a variant constant.
You should use NullDate constant from DateTimePicker unit:

Code: Pascal [Select][+]

DateTimePicker1.Date := DateTimePicker.NullDate;

Quote from: Igor Antić on July 18, 2020, 08:39:34 am

While in Lazarus version 2.0.10 x86_64-win64-win32/win64 works fine.

If NULL appears to work fine, it's by accident. Just use NullDate.

And to test if a DateTimePicker control has Null value you can use either IsNullDate function or DateIsNullMethod of TDateTimePicker:

Code: Pascal [Select][+]

if IsNullDate(DateTimePiker1.Date) then
  ...
 
// or
if DateTimePiker1.DateIsNull then
  ...
 

If this does not solve your problem, please don't continue here, but open a new thread.

Zoran

Null is not a constant — it is a function that returns cleared variant with set the type to varnull:

Code: Pascal [Select][+]

function Null: Variant;
begin
  VarClearProc(TVarData(Result));
  TVarData(Result).VType := varnull;
end;

As there are no variant consts, it is just a parameterless function which always returns the same value.
Not a constant at all. ::)

It doesn't matter — a function is a function, and a constant is a constant, and these concepts must not be mixed up, because they describe two very different things. Incorrect nomenclature misleads the readers, so I advise against this type of simplification.

Or just look to the docs, if you don't know what the Null is. 8-)

The release 2.10 seem an excellent work.
but I compiled my code, with a lot of numerical issues. and tehst on may own benchmark
It compile well with lazarus 2.10 IDE and fpc 3.20 64 bit code..
but the difference with the fpc 3.0.4 is amazing..
The final numerical result is the same but the time to complete the process requires 145 second with fpc 3.0.4 (inside lazarus IDE 2.0.8 )
and 240 seconds with fpc 3.2.0 (inside lazarus 2.10)
the compiling instruction are the same for both compiler (given in project option and without optimization)

Code failures and code lard with no regard of efficiency and speed.
I've already seen some changes in the math code that are unwarranted and frankly has larded up the app with more code and slower speeds.

Every version. Especially getting people to abandon 1.0 was difficult With any change there are winners and losers. The losers didn't properly test RC1 and file bugreports ;-)

It's hard to debug Dll's .
So I am using 3.0.4 generated files which works.
I will report it when I find the problem otherwise I am not clogging up the place half baked thories and hacks.

At least on Windows, it should work (using gdb based debugger). The only part that can be problematic is catching exceptions/raise.

Make sure to compile the dll with debug info.
Specify your "host application" under "run parameters". Make sure the host app can see the dll (i.e. dll is in same folder).

Catching raise/except in the DLL, should work if you strip the host app of all symbols.
With Lazarus trunk it may also work (not tested) if you set the debug option "InternalExceptionBreakSetMethod" to "ibmName".

Breakpoints in the dll should work (they should have a pause symbol, until the dll is loaded. Then they should show the normal symbol. (On older gdb (7.x?), the pause symbol remains)

Reporting installation success of Lazarus 2.0.10 / FPC 3.2 on Win2K. Thanks for the efforts of still providing an installer for that platform. Initially I picked the default (x86_64) installer and didn't even notice that until the very end (fpcmkcfg.exe "not a valid win32 application").

Did a quick compile of some key projects and most went smooth.

Thanks team. Keep up the good work!

Hello,

We have encountered a PPU checksum problem when trying to build Lazarus with cleanup option and with the following packages: BGRAControls and BGLControls. Here is the discussion: https://forum.lazarus.freepascal.org/index.php/topic,24176.msg370399.html#msg370399

Note that both of these packages use BGRABitmap and that the checksum problem is related to BGRABitmap / BGRABitmapTypes units.

Is anyone experiencing very slow response times when running the executable or loading functions such as search/replace? Sometimes it takes 20 seconds or more for the IDE to respond. It seems to be getting worse with time. I'm using the Linux64 version.

DragDrop issue.
Had a project in 2.0.8 with Drag/Drop operations, that ended up functioning great.
Now With 2.0.10 I need to do something similar (with the same user created controls) - and it doesn't function at all.
So fetched my old project recompiled - and it doesn't function any longer, either.

Seems the call to BeginDrag, that should Initiate the dragging with either the dragged control or a TDragObject actually uses the Form as a drag object.
The Source parameter of DragOver (and probably DragDrop) events, is the form.
Can't test Drop, as a drop will never be accepted, when the Source is the form.

Ans it doesn't seem to be the only problem with DragDrop in Lazarus 2.0.10 FPC 3.2.0
Apparently TControl no longer has a FDragCursor variable - see image...
I tried commenting out the first line; seems a little overkill to ask for the same value instead of just setting it (- unless the comparison is a lot faster than than simply assigning a value, I don't know)...
But it - not surprisingly - simply causes the error to move to line 3409...

"cannot access memory at adders 0x164"

Any value that low (below the sizeOf(TControl) ) means that "self" is nil.

@Birger52, if that really is a regression bug introduced between Lazarus 2.0.8 and 2.0.10, we should find the guilty revision.
Can you please study it from the fixes_2_0 SVN branch.
I cannot see any revisions directly dealing with DragDrop.

Post by: Birger52 on July 24, 2020, 04:15:11 pm

I have no idea what you're asking.

All I can do is to determine, that things were functioning in 2.0.8 - and they don't in 2.0.10.
Imagine there may be a million places, things can go wrong.

But I can give you some details.

Control ClipCont is derived from TPanel. Basically a userdrawn panel of a TStringList, with a scrollbar, determining which texts to draw.
Starting drag is done like this:

Code: Pascal [Select][+]

procedure TmyStripPlayForm.SetDragStart(aX,aY:integer); // called at mousedown
begin
  mdX := aX;
  mdY := aY;
end;
 
procedure TmyStripPlayForm.ClipContMouseMove(Sender:TObject;Shift:TShiftState;X,Y:Integer);
begin
  if (ssLeft in Shift) and (mdX > -1) and (mdY > -1) then begin
    if Abs(mdX - X) + Abs(mdY - Y) > 5 then begin
      DragCtrl := ClipCont;
      DragCtrl.BeginDrag(true);
    end;
  end;
end;
 

The use of DragCtrl is nescessary, as Source in DragOver is otherwise the form containing the panels - which is not usefull, and it wasn't like that in 2.0.8 - it was the actual control starting the drag.
DragCtrl is a public var in the Form class.

Following the start of the Drag operation, DragOver is called on the same control that starts the Drag.

Code: Pascal [Select][+]

procedure TmyStripPlayForm.ClipContDragOver(Sender,Source:TObject;X,Y:Integer;State:TDragState;var Accept:Boolean);
var
  dtTyp : byte = dtNone;
  crCur : TCursor;
begin    // Drag over text-Listen af clips
{
  if ((Source = ClipCont) and (ClipCont.SelectedIndex <> ClipCont.DropIndex)) or
     ((Source = ClipImgCont.HeaderLabel) and (ClipImgCont.Selected <> ClipCont.DropIndex)) then
    dtTyp := dtMove or dtExch
  else if (Source = AutoImgCont.HeaderLabel) or (Source = HistoryListCont.HeaderLabel) then
    dtTyp := dtCopy;
}
  if ((DragCtrl = ClipCont) and (ClipCont.SelectedIndex <> ClipCont.DropIndex)) or
     ((DragCtrl = ClipImgCont) and (ClipImgCont.Selected <> ClipCont.DropIndex)) then
    dtTyp := dtMove or dtExch
  else if (DragCtrl = AutoImgCont) or (DragCtrl = HistoryListCont) then
    dtTyp := dtCopy;
  crCur := GetDragCursor(dtTyp);
  TDragControl(DragCtrl).DragCursor := crCur;
  Accept := crCur <> crNoDrop;
end;
 

where

Code: Pascal [Select][+]

  TDragControl = class(TControl)
  published
    property DragCursor;
  end;
 

{commented out code is the code that functioned in 2.0.8.}
The line that causes the problem is here line 19:
DragCtrl is no longer set, for some reason. (and it was Source in the original 2.0.8, and it did not give any runtime errors).
I have debugged MouseMove, and DragCtrl IS set as it should be.
I have tried to debug DragOver - and at least the first time, DragOver is called, DragCtrl IS set, and pointing to the Control that initiate the dragging.
My programming do nothing to unset DragCtrl - except when ending the drag, when it is set to nil.
If the drag has been ended, DragOver should not be called. (Debugging, execution doesn't get to where it is set to nil.)
And besides - Once the drag is initiated, it is the drag Manager that controls what is happening, and no code of mine - except DragOver and DragDrop event handlers - should be called.

There are other packages that use sparta generics package so sooner or later you will again face the PPU problem. If you follow the PascalDragon's fix then you can use both embedded form designer and other packages using sparta generics without problems. More info:

The Lazarus team is glad to announce the release of Lazarus 2.0.10.

http://wiki.freepascal.org/Lazarus_2.0_fixes_branch

Thank you all for this new release, which I installed after a complete uninstall of 2.0.8. I have two questions though.

1)
New complaints from the compiler:
wellform.pas(5740,31) Note: Call to subroutine "function TChartAxis.GetMarks:TChartAxisMarks;" marked as inline is not inlined
They arise every time I change properties of the marks. Everything seems to work just fine. Can I happily ignore them?

2)
TStringStream and TMemoryStream used to have a common ancestor in previous versions, now TStringStream is derived from the TMemoryStream. I could not find anything about this change in the release notes. Is there an explantion for this change?
In my case I tested if AStream is TMemoryStream then... to distinguish between binary data and real text data. Now my data reading failed for text data because they were handled as binairy data. It took a while before I onderstood what went wrong. In the end I changed the test to if not (AStream is TStringStream) then ... to get it working again. This construct proved to work also in 2.0.8.

Thanks in advance for any comments.

You can ignore it without fear. The compiler has always decided whether subroutine marked as inline was really inlined or not, according to some determined set of rules, but it did it silently. Now it emits a note to let you know if that is the case; that's all there is to it.

This change was needed to support correct handling of encoding and it's also Delphi-compatible. I've now documented it here (https://wiki.freepascal.org/User_Changes_3.2.0#TStringStream_derives_from_TBytesStream) with the already documented, related changes.

Dragging the IDE editor tabs is also showing strange behaviour - a 'no drop' cursor flies off to unrelated screen positions when a drag is attempted, though sometimes the usual double arrow cursor appears briefly in roughly the right place. It looks very much like what has also been happening in my application. This is on a .deb reinstall (64-bit MXLinux 19.1 / GTK2) . I have never experienced anything similar using 2.0.08.

Re drag issue, the problem does not appear in my Windows 7 Lazarus install ver 2.0.10 r63526, either in the IDE or my applications. One Linux version which does show the problem is from Sourceforge, about info is dated 2020/07/07 (FPC 3.2.0 again) and marked 'Unversioned'; lazarus built from source today has the same behaviour. Hope this may narrow it down a little.

I'd like to confirm that for 32Bit Ubuntu Xenial, .deb install from Sourceforge. Sometimes you even end up with closing a tab instead of successfully dragging one.

Hi, I appreciate the work of the Lazarus Team, but I really do not understand the way of the release cycles. The release 2.0.10 was so buggy that I went back to 2.0.8 - always in the hope to see a bug-fixed version released of the 2.0.10 - this is a couple of weeks now and I still did not see any bug-fixed version. Where would I be able to download at least a release candidate of the next version which includes all free pascal bugfixes? Is the only way really for everyone to compile everything from scratch? That is not really user friendly, nor does it seem to work straight out of the box. I gave up at the end and continue working with the 2.0.8 release on all my OSes. That makes me sad, would of course prefer the most current version of lazarus. I addressed the UUID Bug in the current FPC Postgresql libs, it got fixed in the FPC branch, but I see no way for myself to get it into the current release of lazarus ... so again, is there a way to find a more current binary version than the one Lazarus Release 2.0.10 - July 11, 2020, 10:55:58 am... that one is unusable for me due to the bug of the fpc.
In general, I am more or less experienced on linux and windows, but if I give up doing it myself, this means something in the process documentation is broken. I do not mind helping, though, and I love Lazarus, so please do not misunderstand this post, and I certainly do not want anyone to stop his engagement ... keep on - just make it SIMPLER somehow for people like me :-) %)

I'm sorry to hear you have problems with the Lazarus current version.

I guess you maybe already know Lazarus needs more volunteers. There is always something we can participate. Bug hunting and reporting, improving the documentation and wiki, answering newbie's question in the forum, and more.

If you found something not working as what it should be you can post it on the bugtracker. But if you're not sure, you can discuss it here before posting on the bugtracker.

I believe your problems came from the FPC version jump.
Lazarus 2.0.8 came with FPC 3.0.4.
Lazarus 2.0.10 came with FPC 3.2.
It is a big difference because FPC release cycle is slow. I think it was a well justified move anyways because FPC 3.0.4 is ancient and FPC 3.2 now gets more testing.
You can install FPC of your choice separately and then Lazarus from SVN server, either branch fixes_2_0 or trunk.
https://wiki.freepascal.org/Getting_Lazarus
You can have many SVN versions of Lazarus in your machine. Just build and start them from their directory. No installation needed.

This is the list of merged revisions in Lazarus 2.0.10 :
https://wiki.freepascal.org/Lazarus_2.0_fixes_branch#Fixes_for_2.0.10_.28merged.29
I believe it has less bugs than 2.0.8.

If you run into problems, post in the appropriate forum and I'm fairly certain someone will provide the solutions.

I have various FPC versions and Lazarus versions installed, along with trunk FPC and Lazarus compiled from source. It is a relatively easy process to switch Lazarus between versions of FPC (I have 3.0.4, 3.2.0 and trunk). It is also worth reading the FPC Release Notes and User Changes documents for each version of FPC (see this Wiki Listing (https://wiki.freepascal.org/Category:Release_Notes)).

FPC releases have nothing to do with Lazarus releases. There is currently no timeframe when the next FPC release (3.2.2) will be done which would contain the fixes you mentioned, thus there can not be a Lazarus release with a newer FPC release, because there is none. You can however compile FPC 3.2.1 yourself and use that. This would probably also help to find further problems, because without any bug reports we won't know what needs to be fixed.

This always happened to me since lazarus 1.8x I think. I still remembered working on project some 5 years ago. it happened. The docked IDE is just unstable. I'm not even using spartadock. And always disabled auto save layout. I think there's some layout that can't be loaded after being saved so it messed up the layout. The layout list also missing. But if I keep lazarus running. fixing the layout. The list magically appeared again. So, I always have a copy of lazarus config with healthy layout. It still happens sometimes.

Dear team,

As always users are more stupid than the designers intended, so here is my attempt:

Start a new application, drop a chart and add two lineseries to the chart.

Code: Pascal [Select][+]

 
TForm1 = class(TForm)
    Chart1: TChart;
    Chart1LineSeries1: TLineSeries;
    Chart1LineSeries2: TLineSeries;
  private                     
...

And now: save this first!
Then right-click in the component list on one of the series and try to change the class to a TFuncSeries. Lcl will remove invalid values and ... crash completely. See the last of traces of life in the att.

Hi, except you are a teen, don't do that. 8) You can't complain something you cant explain clearly.
BUT, I also experience a bad think when installing Lazarus v 2.0.10 yesterday.
BUT, after reading some text (in lazarus's source-forge download page) that was actually my vault >:D !
That is, I think that by installing "cross-32-64" then will able to compile for 32/64 switchable automatically. I was wrong, you @Gebo might be also be wrong if thinking of the same assumption.

So, I did both 2 way below, and each of them is okay:
1. Instal the Lazarus-64bit for windows, and then install the Lazarus cross-32-64 (be carefull to download 2 files from same page)
2. Instal the Lazarus-32bit for windows, and then install the Lazarus cross-32-64 (be carefull to download 2 files from same page)

When everyone who is complaining bothers to either lodge bugs in the BugTracker (https://bugs.freepascal.org/view_all_bug_page.php?project_id=1) after using the appropriate (not here! This sub-forum "Announcements > Lazarus" is supposed to be for Lazarus release announcements) sub-forum to check if others have the same issue.

And even if not, Lazarus has a relatively quick release cycle of about six to twelve months, so a new release can be expected anytime between now and Summer. If it's a 2.0.12, I'd expect it for early Spring, if 2.2.0 then it'll probably be delayed until Summer :-X

But, of course, trev is right: if you have problems, use the proper forum thread and/or the bug tracker and describe the problemmore thoroughly; just moaning that something "doesn't work" is not very helpful ;)

The real problem is that unless you have reported, quite specifically, what is troubling you, the next release will almost certainly have the same problem. So, write down what you want fixed, in a way that someone else can reproduce (keeping in mind that just about everyone else is happy with 2.0.10). Post to an appropriate Forum thread (not this one) if you are unsure if its a bug or user error. If you are sure its a bug, log it in the bug tracker.

That way, there is a chance that the next release will not have the same problem.

I'm happy with Lazarus 2.0.10 and fpc 3.2.0. We have a large cross-platform project for Windows and Mac.

Recently I found a couple of problems and submited bug-reports for fpc and Lazarus. Those problems were quickly fixed.

Dear team,

As always users are more stupid than the designers intended, so here is my attempt:

Start a new application, drop a chart and add two lineseries to the chart.
Code: Pascal [Select][+][-]

TForm1 = class(TForm)
Chart1: TChart;
Chart1LineSeries1: TLineSeries;
Chart1LineSeries2: TLineSeries;
private
...

And now: save this first!
Then right-click in the component list on one of the series and try to change the class to a TFuncSeries. Lcl will remove invalid values and ... crash completely. See the last of traces of life in the att.

Issue reported to bug tracker (https://bugs.freepascal.org/view.php?id=38375).

Please do not add bug reports to announcements, report them in the bug tracker or at least in the related sub-board. It's been only by chance that I came across this post here...

Just a quick note. Manjaro does a pretty good job of automatically keeping me up to date with Lazarus. I'm using 2.0.10 (Date: 2021-01-13) FPC 3.2.0, SVN Revision: Unversioned directory, x86_64-linux-gtk2. As always - thanks to the team. This is a very sleek and friendly IDE and I love working with it. :)

Всем привет!
I'm using Lazarus 2.0.10 r63526 (installed via FPCUPDeluxe).

Operating system Windows 7 64 (not observed in Linux, and not observed in Windows 32).

Native application (not using LCL !!! Personally, I use ZenGL). Periodically, when trying to debug (using an external debug file) - the debugging itself can be completely ignored. Breakpoints are ignored.
