Custom Query

Some of them are from older AutoIt's ToDo lists and other comes from forum.

I think some of the forum's scripts/UDFs could be as AutoIt's standard.

Original post is here: ​http://www.autoitscript.com/forum/[index.php?s=&showtopic=70888&view=findpost&p=519126] due to antispam restrictions on BugTrac (too many links)

OS = WinXP SP2 RAM = 2.00Gb AutoIt Ver = 3.2.11.12

I'm not sure if this is a bug or some limit of Window or AutoIt

Background: I'm working with some large text files 200Gb to 400Gb and found that any of the file functions that use FileRead() generate an error, even though Task Manager shows plenty of memory left, in the form of a message box Title = 'AutoIt' Text = 'Error allocating memory.'

I can work around this by processing the files line by line, but obviously this is much slower.

Observations: The help file give the theoretical limit 2147483647 characters but it would appear that it is impossible to get anywhere near this limit.

I created the scripts to try and find exactly what the limit is on my system. The results seem to show that the limit is some sort of global memory limit within AutoIt, rather than a limit for each string, as each time I double the number string variable filled the total memory used before the error allocating memory occurs is approximately the same.

Should AutoIt be able to make use of more of the memory available to it?

Script 1

#Include <String.au3>
Local $sString = _StringRepeat( "A", 1024)
Local $iCount = 0
Local $sTest1 =''

While 1
	$sTest1 &= $sString
	$iCount += 1	
	ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $iCount = ' & $iCount & @crlf & '>Error code: ' & @error & @crlf) ;### Debug Console
WEnd

Script 2

#Include <String.au3>
Local $sString = _StringRepeat( "A", 1024)
Local $iCount = 0
Local $sTest1 =''
Local $sTest2 =''

While 1
	$sTest1 &= $sString
	$iCount += 1	
	ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $iCount = ' & $iCount & @crlf & '>Error code: ' & @error & @crlf) ;### Debug Console
	$sTest2 &= $sString
	$iCount += 1	
	ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $iCount = ' & $iCount & @crlf & '>Error code: ' & @error & @crlf) ;### Debug Console
WEnd

Script 3

#Include <String.au3>
Local $sString = _StringRepeat( "A", 1024)
Local $iCount = 0
Local $sTest1 =''
Local $sTest2 =''
Local $sTest3 =''
Local $sTest4 =''

While 1
	$sTest1 &= $sString
	$iCount += 1	
	ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $iCount = ' & $iCount & @crlf & '>Error code: ' & @error & @crlf) ;### Debug Console
	$sTest2 &= $sString
	$iCount += 1	
	ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $iCount = ' & $iCount & @crlf & '>Error code: ' & @error & @crlf) ;### Debug Console
	$sTest3 &= $sString
	$iCount += 1	
	ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $iCount = ' & $iCount & @crlf & '>Error code: ' & @error & @crlf) ;### Debug Console
	$sTest4 &= $sString
	$iCount += 1	
	ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $iCount = ' & $iCount & @crlf & '>Error code: ' & @error & @crlf) ;### Debug Console
WEnd

Maximum values of $iCount which equates to the size of the $sTextn Script 1 = 262142Kb in 1 string Script 2 = 262141Kb in 2 strings Script 3 = 262139Kb in 4 strings

Some support for "Debug mode" directly inside AtoIt to help incorporate some debug modes/options in editors.

This is based on older AutoIt's ToDo lists.
