#42556 [Opn->Fbk]: snmpget() on win32 returns wrong strings (backslash/escaping problem)

ID: 42556 Updated by: jani@php.net Reported By: bugs dot php dot net at marnik dot org -Status: Open +Status: Feedback Bug Type: SNMP related Operating System: win32 only PHP Version: 5CVS-2007-09-05 (snap) New Comment: Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows: http://windows.php.net/snapshots/ Previous Comments: ------------------------------------------------------------------------ [2007-09-05 08:22:32] bugs dot php dot net at marnik dot org Description: ------------ When using snmpget() on Windows 2003 or Windows XP to retrieve strings wrong strings are returned when they contain backslashes (for example when Paths are used). Setting the string works fine, but when there are x number of backslahes in the strings, when using snmpget() to retrieve this string, the last x number of characters are missing and the backslashes \ are replaced with \\. It looks like the stringlength is calculated first, and the string is escaped afterwards, thus truncating the last characters. (I tried to locate the bug in the sourcecode but I got lost) As you can see in the sample, the returned strings are missing the last characters. Note that this bug was already reported but is in the "no feedback" state, I got it re-opened but was told to report a new bug. The old bug is http://bugs.php.net/bug.php?id=32935. Reproduce code: --------------- <?php print_r(snmpwalk("127.0.0.1","public", ".1.3.6.1.2.1.25.4.2.1.4")); ?> Expected result: ---------------- The full program paths displayed, where appropriate.
