AutoIt v3.3.15.5 Beta issue with _pathsplit


Go to solution Solved by erha,

Recommended Posts

This is my first post - I hope I follow all rules ūüėÄ

I have used the portable autoit version 3.3.15.4 Beta. After switching to 3.3.15.5 Beta I could run my programs from scite but the compilation crashes.

For some reasons compile uses _PathSplit. In case the parameter $sFilePath is an empty string, _PathSplit crashes.

_PathSplit uses

Local $aArray = StringRegExp($sFilePath, "^\h*((?:\\\\\?\\)*(\\\\[^\?\/\\]+|[A-Za-z]:)?(.*[\/\\]\h*)?((?:[^\.\/\\]|(?(?=\.[^\/\\]*\.)\.))*)?([^\/\\]*))$", $STR_REGEXPARRAYMATCH)


AutoIt version 3.3.15.4 returns an array with 5, AutoIt version 3.3.15.5 returns an array with 3 elements. The missing two elements are the reason for the crash.

I have used this test program:

#include "StringConstants.au3"

Local $sFilePath = ''
Local $aArray = StringRegExp($sFilePath, "^\h*((?:\\\\\?\\)*(\\\\[^\?\/\\]+|[A-Za-z]:)?(.*[\/\\]\h*)?((?:[^\.\/\\]|(?(?=\.[^\/\\]*\.)\.))*)?([^\/\\]*))$", $STR_REGEXPARRAYMATCH)
MsgBox ( 0,0, UBound($aArray)  )

As a workaround I changed _PathSplit to

Func _PathSplit($sFilePath, ByRef $sDrive, ByRef $sDir, ByRef $sFileName, ByRef $sExtension)
    Local $aArray = StringRegExp($sFilePath, "^\h*((?:\\\\\?\\)*(\\\\[^\?\/\\]+|[A-Za-z]:)?(.*[\/\\]\h*)?((?:[^\.\/\\]|(?(?=\.[^\/\\]*\.)\.))*)?([^\/\\]*))$", $STR_REGEXPARRAYMATCH)
    If @error Then ; This error should never happen.
        ReDim $aArray[5]
        $aArray[$PATH_ORIGINAL] = $sFilePath
    EndIf
    if UBound ( $aArray) < 5 Then ; ### my change
        ReDim $aArray[5]
        $aArray[$PATH_ORIGINAL] = $sFilePath
    endif
    ...

After this change I can compile my programs.

Could you also post an script that uses pathsplit demonstrating your issue?

 

Ps I've split it into its own topic in support. :)

@Jos  I get also the problem on non-portable.  

#include <File.au3>
#include <Array.au3>

Local $sDrive, $sDir, $sFileName, $sExtension
Local $arr = _PathSplit("", $sDrive, $sDir, $sFileName, $sExtension)
_ArrayDisplay($arr, @AutoItVersion)

Both SRE (current and beta) are identical.  It might be the fix #2696: StringRegExp non-participating groups that causes the problem.

@Jos

Nine has posted the script i just wanted to post too. His script crashes in the new autoit version. The error message is

"D:\System\Programme\Portable\AutoIt\Current\Include\File.au3" (1012) : ==> Array variable has incorrect number of subscripts or subscript dimension range exceeded.:
$sFileName = $aArray[$PATH_FILENAME]
$sFileName = ^ ERROR

Crashes on :

"Test"
"Test.txt"
"\Test.txt"
"..\Test.txt"

In other words, it does not crash only when a full path is pass to the function

Tnx,  reopened https://www.autoitscript.com/trac/autoit/ticket/2696 so it can be checked. :)

Same for me - The error happens almost immediately when asking for "Tools/Compile" from SCITE. It works when asking for "Tools/Build" 

......\Include\File.au3" (1012) : ==> Array variable has incorrect number of subscripts or subscript dimension range exceeded.:
$sFileName = $aArray[$PATH_FILENAME]
$sFileName = ^ ERROR

No error when compilation is outside of Scite.

I tried your repro and after few more test I found out other issue AutoIt3.exe ended.rc:-1073741571 with this repro:

#AutoIt3Wrapper_AutoIt3Dir="z:\AutoItPortable\AutoIt_3_3_16_0_rc1"
#AutoIt3Wrapper_UseX64=n

ConsoleWrite("! " & @AutoItVersion & @CRLF)

_Example3()

Func _Example3()
    Local Const $s_RegExp = _ ; $s_RegExp comes from Func _PathSplit(
            '^\h*((?:\\\\\?\\)*(\\\\[^\?\/\\]+|[A-Za-z]:)?(.*[\/\\]\h*)?((?:[^\.\/\\]|(?(?=\.[^\/\\]*\.)\.))*)?([^\/\\]*))$'

    Local $sString = 'xxxxxxxxxx'
    For $iCounter = 1 To 11
        ConsoleWrite("- step #" & $iCounter & ' StringLen= ' & StringLen($sString) & @CRLF)
        StringRegExp($sString, $s_RegExp, 0)
        $sString &= $sString
    Next
EndFunc   ;==>_Example3

Not looking at old bugs. This thing is going out the door.

Reverted the string reg exp groups change and that looks to fix the crash. Will create a new installer.

I don't undertand what happen with 3.3.16.0-rc1

What I am sure is the propose patch  to Jon was OK. I cannot reproduce any error mention above.

I agree that the support of non participating group return difference which are the right way to return

Just use https://regex101.com/ to validate your pattern.

Previously StringRegExp() was returning extra group.

In fact nobody can give me a pattern which was ok without any adaptation to _PathSplit()

The _PathSplit() has been adapted to handle these differences.

Cheers

Edited: I recheck what was included in 3.3.16.0.rc1 and I found Jon forget to update the File.au3

Indeed I've been unable to find a reasonable pattern to match every form a path can have.
