Re: Stupid ExcludeTrailingPathdelimiter question

Bart — 2013-05-19T14:17:38


That only works if you use the LazFileUtils version.
The one from FileUtil behaves just liek excludeTrailingPathdelimiter().

Re: Compiler bug with managed type not being initializedcorrectly

Paul Ishenin — 2013-05-18T14:13:41


I tested the given example and I can't see any error. Although I tested 
on win32 platform.

Please compile RTL with debug information and try to debug 
fpc_Initialize routine from rtti.inc.

During the testing of your example I see that it executes on each enter 
to Test1 and Test2:

1. It steps into tkRecord case of fpc_initialize and then enters to 
recordrtti
2. In recordrtti Count = 1 (1 managed field), so it executes the 
for-loop body 1 time.
3. In for loop it enters rttiproc = fpc_initialize with Offset = 0 and 
TypeInfo of tkInterface.
4. In fpc_initialize it assignes nil to Data (interface field).

If in your case you see something else please reply to this mail or to 
the bug tracker.

Best regards,
Paul Ishenin

Compiler bug with managed type not being initializedcorrectly

Anthony Walter — 2013-05-18T01:41:28

I just filed a bug having to do with a managed type (I am using an
interface in my code) not being properly initialized when stored in a
record's private section:

http://bugs.freepascal.org/view.php?id=24447

I marked the issue as major since I thought this kind of issue (managed
types slipping through initialization should never happen. If anyone want
more clarity on this issue let me know. As an added note, if this situation
causes an interface to not be initialized,it probably also has problems
with finalization that need being looked at as well.

Managed types described (as best as I could find):

-v to show function call frequency

leledumbo — 2013-05-18T00:55:28

Is there any -v (or any other option) to show summary of function call
frequency (in term of appearance in source code, not actual function call)?
i.e. something like:

program A:
routine        times called
--------------------------------
function1      10
procedure1     5
function2       1

units B:
routine        times called
--------------------------------
procedure1     3
procedure2     2

Re: Examples of tiOPF logging in the wild

Graeme Geldenhuys — 2013-05-16T14:02:08

Simply edit the tiLogToGUI unit for your chosen toolkit (VCL, LCL or
fpGUI), and edit the CreateForm() method to suite your needs.



That is indeed true, and hence the reason for the FormParent property. I
have heard of other developer that used this in Delphi, but I have never
tried to embedded in inside another form myself.

Seeing that you posted here, I'll assume you are using LCL. The next
question would be: "Does LCL support reparenting of components or
forms?" I have no idea.


Tip:
In future I suggest you post tiOPF related questions in the tiOPF
support newsgroups. You will find more tiOPF experienced users there,
and probably a better change of getting answers.

For completeness: I've certainly got a Delphi program that can "shell

Yes, but your message could be interpreted as suggesting that this person, who was clearly calling Makefiles in subdirectories directly rather than using the top-level Makefile, should have first compiled the new compiler directly, and then compile the new RTL using this new compiler. Given the amazingly creative ways in which people manage to keep trying to compile FPC in unsupported ways, I did not want anyone to get the idea that this would be a good approach.

Re: Documentation site: incorrect manual name

I think it's the documentation source that needs to be updated, FCL always
means Free Component Library.

Examples of tiOPF logging in the wild

vfclists . — 2013-05-16T13:27:57

Are there some examples of using tiOPF logging besides those in the demos?


I want to use tiLogToGUI, but I am not happy with the amount of screen
space it takes. Is there some way it can be adapted or themed to be tidier
or smaller?

The code gives the impression that it can be embedded or extended in
another form or is
that a misconception on my part?

Reimar Grabowski — 2013-05-16T12:46:16

Same problem here but much funnier FPC message:

Makefile:2704: *** The only supported starting compiler version is
2.7.1. You are trying to build with 2.6.2. If you are absolutely sure
that the current compiler is built from the exact same
version/revision, you can try to use OVERRIDEVERSIONCHECK=1 to
override .  Stop.

So I had to use OVERRIDEVERSIONCHECK=1 to build my 2.7.1 with 2.6.2. IMHO that's not as intended.
But it may be a problem of the create_fpc_deb script provided by Lazarus so from my side there is no need for any actions.
Just wanted to share that funny message.

TProcess, Batch script and Windows

Marcos Douglas — 2013-05-15T13:37:47

Hi,

I want to execute a batch file on Windows (FPC 2.6.2 and Laz trunk)
using TProcess class.
It ONLY works if I use the [poWaitOnExit] and DO NOT USE [poNoConsole] options.

I do not want to see the console so, I need to use [poNoConsole]
option. Is this a bug?

I'm sending a project test in attachment. Thanks,

Best regards,
Marcos Douglas
