I'm adding some clarification and context to your ongoing comments about

What Michael also keeps forgetting, is that EpikTimer gives a unified
timing interface, which is very handy in cross-platform applications.
Yes we could manually use QueryPerformanceCounter under Windows,
clock_gettime() under Linux and FreeBSD, and fpgettimeofday() everywhere
else but EpikTimer gives us a clean API to use, and takes care of
the platform differences for us. Makes for much cleaner code in our
applications, which I personally think is nice!


I have never tried to suggest that a component as epiktimer does not fill a gap.

Once more, the only issue I am having is the continued suggestion that it is better and 
offers more fine-grained/accurate timing than simply using now() when going cross-platform.


If the result of my continued hammering is that now someone will actually 
contribute
improvements, I can only appreciate the effort and you won't hear me about it 
ever again.

Hello Leonardo,

I'm flattered with your comment.

We can add a new file, called WHATS_NEW.txt, and it can be rewritten in all new

version.

What do you think of this idea?


Go for it !

It seems that a syscall is not necessary with some / many environments.

vDSO seems to provide a user-land implementation in (many) current

Maybe directly accessing the appropriate CPU registers is possible /

[Lazarus] Fpcup problem with Lazarus

2014-05-19 Thread Koenraad Lelong

Hi,

I tried fpcup to get a user version of lazarus. With that I mean a 
version of lazarus where adding packages is more easy than with a 
packaged version of lazarus.

But I'm exeriencing a problem.
I ran fpcup and all seems OK, but when I make a simple project, form 
with a button, I can't double click on the button to give it an 
OnClick-event. I get an error (on the commandline) :

TDesigner.InvokeComponentEditor A Button1:TButton
TDesigner.InvokeComponentEditor B TDefaultComponentEditor
### TCodeToolManager.HandleException: unit not found: Classes at 
Line=26 Col=10 in /home/koenraad/development/lazarus/lcl/lclclasses.pp
TDesigner.InvokeComponentEditor ERROR: Unable to find method. Please fix 
the error shown in the message window, which is normally below the 
source editor.

In the lazarus-IDE I also get an error-message, stating the same.

I'm running linux. My lazarus is at svn rev. 45085.

What's wrong ?

There's no question that the component needs an update as the current zip
on the Lazarus-ccr was packaged in 2006. SVN is more current and Graeme and
I will get together and roll any additional improvements he's made into a
new release.

If we need to make improvements to the core measurement routines for better
cross platform support, some additional input would be helpful. For
hardware timing, I see the following support across processor types:

http://en.wikipedia.org/wiki/Hardware_performance_counter

There is a Performance API (PAPI) standard for cross platform access to
those counters, but probably not a candidate as it requires OS support.
Regarding OS based timing, my experience is limited to Linux and Intel/AMD,
so if there's a more universal approach, I'd be very interested in learning
more about it.

Thanks,

-Tom

I'll let you take care of that then I don't have access to create a
new bare git repo in Lazarus-CCR.

In the mean time, I created a Git clone from the SubVersion Lazarus-CCR
which contains the full history for EpikTimer (as of this morning). I
published that at my Github account as the master branch.

I then created another branch called gg-changes which contains some of
my changes. I have multiple copies of EpikTimer on my various systems -
I'll go through them all to collect all other changes too.

Here is a pull request summary:

The following changes since commit 9024600e (master):

Once you have setup a bare git repo on Lazarus-CCR you should be able to
clone my Github one, and simply push it to Lazarus-CCR to retain the
full history (at least the master branch). My gg-changes branch is
obviously up to you.
