Bug #61309 [NEW]: DBCS included UNC path broken due to incorrect toupper usage

From: Operating system: Windows Server 2008 R2 Foundatio PHP version: trunk-SVN-2012-03-07 (snap) Package: Directory function related Bug Type: Bug Bug description:DBCS included UNC path broken due to incorrect toupper usage Description: ------------ scandir() fails on all of following conditions: - use UNC path with DBCS character(s). - second byte in one DBCS character includes lower letter ('a' to 'z'). for example: \\DD5\フォルダ ("フォルダ" means "folder") each character -> to byte array as CP932 (aka Shift_JIS) -> to ascii: フ -> 83 74 -> .t ォ -> 83 48 -> .H ル -> 83 8B -> .. ダ -> 83 5F -> ._ incorrect toupper usage brings "サォルダ" from "フォルダ". Expected result shows: By using pathced php5, it is looking for right place "\\DD5\フォルダ" (ok). [CASE1] in Actual result shows: By using php5 snap, it is looking for wrong place "\\DD5\サォルダ" (wrong). network path is not found! [CASE2] in Actual result shows: By using php5 snap. I prepared a UNC folder with wrong name "サォルダ". About my fix method: - toupper/tolower is ok, however path consists from "characters", not "bytes". - try _mbsinc or such to advance pointer in "character" unit. Test script: --------------- <?php echo print_r(scandir("\\\\DD5\\フォルダ")); ?> Expected result: ---------------- C:\php-sdk\php54dev\vc9\x86\php5.4-201203070030>Release_TS\php.exe \php5\test.php Array ( [0] => .
