I thought the file attributes are ignored under linux, but apparently they are not.
Is it normal, that FindNext returns a file twice?

uses
  SysUtils;
var
  Info: TSearchRec;
begin
  if FindFirst('*',faDirectory,Info)=0 then
  begin
    repeat
      writeln(Info.Name);
    until FindNext(Info)0;
  end;
  FindClose(Info);
end;

With faAnyFile every file is listed only once.

Would that explain why the TFileListBox component and Lazarus's "File Browser" add-on shows double files under my Linux system.

And sometimes even more than twice as the following output shows (using the code you posted). This is the exact behaviour I get with TFileListBox and "File Browser" lazarus add-on.

Yes.

It seems it is buggy under OS X too.
I guess, this must be added to the wiki pages about cross platform issues.

Yes.

Ah. And using faAnyFile and then testing .Attr for faDirectory is one way to overcome the problem.

I'm using FPC 2.2.5 but noticed this issue some time ago, but could never pinpoint it. It might be good to report it on the wiki, but it should definitely be reported as a bug in FPC Mantis as well. Kylix doesn't have this issue.

They are currently ignored if you do not use wildcards, otherwise they are used. I'm tested a fix to change that so that they are always used.

No.

With faAnyFile every file is listed only once.

I'm testing a fix for this as well.

Thanks. I hope this will not slow down things. I have some programs that scan directories with millions of files. (Don't ask)

No need to fix faAnyFile. I like the only once. ;)

Mattias

It's fixed in r13074. It will slow down things slightly if you don't use wildcards, since some memory is now allocated and released for the non-wildcard searches (whereas this previously was not the case).
