LazProfiler (beta)

[El Salvador]

Will LazProfiler be available with Lazarus 2.0.10 (FPC 3.2.0)?

It is broken. I comment all writeln to avoid error message in opening project, but TPascalScanner will raise 'No support for resources of type "%s"' (.lfm or .res).

You need to add po_IgnoreUnknownResource to the scanner's Options property.

So, I need use FPC Trunk version, right? Thanks.

Works on trunk laz&fpc fine.

I came here from the FreePascal wiki LazProfiler page and I am being warned by the forum to not comment since there has been no post for 120 days...
But this is clearly the support page for LazProfiler, right?

So I would like to get some usage help:

1- Does this work on Lazarus 2.0.12 and FPC 3.2.0 in ARM Linux (Raspberry Pi)?
I see requirements like these:
FPC trunk (needs generics and additional PascalParser funktionality) or fixes_3_2
Lazarus trunk (revision 60719 and above) or fixes_2_0
But I am using tagged releases 2.0.12 and 3.2.0, will that not work?
Lazarus Help/About states revision 64944

2- Does LazProfiler work for a command line program (no GUI parts) running as a systemd service?

3- I need the profiler in order to find why my application when running idle still eats 10% CPU on Linux.
Can this be done? There is no memory usage problem just the fact that it sits at 10% CPU while just waiting.

The application is running a TCP service so a user can connect to it using  a custom application in order to configure its operations and download data. It is meant to be used as a systemd service but can be started manually on the command line as well.
The application is itself a scheduler for measurement operations configured to start at certain times and run with certain job data used by an attached instrument (by RS232).
When it is waiting for a client connection or the time to start a measurement operation it should idle at close to 0% CPU usage but in fact it uses 10% as shown by the top command.
I need to find where this happens....

The application was ported from Delphi 2007 into FPC using Lazarus.

Hi, this is still maintained?

On FPC 3.2.2 Lazarus 2.2.4 doesn't works, it gives an error when opening a lpi file or a form.

I'm very interested in this project. In the absence of a response about its status, I try to wake up the thread. I hope the author, who is a forum member and did a great job, can reply. Thanks in advance.

I contacted him by PM and he says that is open to new pull requests to fix the code.

@AlexTP do you still use LazProfiler? If yes, did you made some changes available to share?
I don't know if it will be useful for me or not, but I tried to make it work with latest of Lazarus, too many errors, WriteLn and other problems.

[AlexTP]

I was not able to use LazProfiler (was not able to measure function times), and did not make changes.

[Okoba]

Thank you. Do you use any profiler for CudaText?

[AlexTP]

I do not; the optimizations of CudaText is done by looking where app 'hangs' on handling huge documents. I use 'Pause execution' and see 'call stack'.

[Okoba]

Pause execution?

[AlexTP]

IDE has the "Pause" button on toolbar, near "Run" button.

Thank you so much.
