[ruby-core:56656] [ruby-trunk - Bug #8795] "Null byte in string error" on Marshal.load

From: "mml (McClain Looney)" <m@...>
Date: 2013-08-16 16:46:06 UTC
List: ruby-core #56656
Issue #8795 has been updated by mml (McClain Looney).


seems the call to memchr on line 1496 of string.c is returning truthy. The string passed to it is 11 bytes of null (0x00). You can see these bytes in the input starting at offset 19592. not sure what they are for, or where they came from.. 

----------------------------------------
Bug #8795: "Null byte in string error" on Marshal.load
https://bugs.ruby-lang.org/issues/8795#change-41193

Author: mml (McClain Looney)
Status: Open
Priority: Normal
Assignee: 
Category: core
Target version: 
ruby -v: ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN


I have about 2M serialized ruby objects in a database (don't ask). The objects are serialized via Marshal.dump, then zipped, then base64 encoded before being saved.  After upgrading to 2.0 (built from source), a tiny minority (3-4) of objects thusly stored will fail to Marshal.load, with "ArgumentError: Null byte in string"

Given that the other 1.9M objects load just fine, and the issue never manifested in 1.8.7 MRI, and further, that the zip CRC's & such were not corrupted, I suspect there may be some subtle bug in the Marshal.dump code.

Please see attached file for a sample.  I'd be happy if there'd even be any way to "fix" said broken string, or even any insight into what might be going on, but I'm more worried that there may be a Marshal bug lurking..
