MultipartRequest class incorrectly parses form post when field boundary occurs near end of
internal buffer
----------------------------------------------------------------------------------------------------------
Key: JBSEAM-1323
URL: http://jira.jboss.com/jira/browse/JBSEAM-1323
Project: JBoss Seam
Issue Type: Bug
Components: Core
Affects Versions: 1.2.1.GA, 1.2.0.GA
Environment: Windows Vista, Firefox 2.0.0, Java 1.6u1, JBoss AS 4.0.5.GA, JBoss
Seam 1.2.1
Reporter: ROB b
Fix For: 1.3.0.BETA1
When a form post is processed by a MultipartRequest class and it has a field boundary that
occurs near the end of the internal buffer of the MultipartRequest class, it fails to
recognize the field boundary and interprets the field boundary and the following header to
be a part of the previous field's contents.
This bug can most easily be reproduced by creating a form of
enctype="multipart/form-data" with 30 <h:inputText> fields. The fields
should be submitted empty. This provides form post data with lots of field boundaries and
little in between. One of the field boundaries is likely to be near the end of the 2KB
class buffer. When the bug occurs, one of the blank fields will be shown to contain part
of the form boundary text. The form may have to be submitted 5 or 10 times, before the bug
occurs.
This same technique also occasionally causes the JBSEAM-1322 bug to occur (rarely,
though).
Sorry, I don't have a suggested fix. The class has been kind of hard for me to debug.
Submitting the following XHTML source multiple times can be used to demonstrate the bug:

-------------------------------
I submitted the test form provided in my previous comment with the as-of-this-moment
latest CVS version of Seam on JBoss AS 4.2.0.GA. The exception related to JBSEAM-1322 is
no longer occuring (thanks for fixing it), but I still am having the same problem
described in this issue record.
The erroneous form data appears when I submit the blank, before-mentioned form. If you are
not able to reproduce this bug please let me know, but I do not believe it is specific to
my dev environment.

Resolution: Done
Seems to be fixed now, the bug was in the checkSequence() method - it was returning false
for any checks where the byte sequence started on index 0 of the array.

----------------------------------------------
In some cases, an input will not be in the request param map (yes it was sent in the
header).
Before the input would be populated with wrong value (part of the boundary itself), now it
is just missing. See the header below...
somehow SAQCUP7 doesn't get added to the param map

MultipartRequest class incorrectly parses form post when field
boundary occurs near end of internal buffer
----------------------------------------------------------------------------------------------------------
Key: JBSEAM-1323
URL: http://jira.jboss.com/jira/browse/JBSEAM-1323
Project: JBoss Seam
Issue Type: Bug
Components: Core
Affects Versions: 1.2.1.GA, 1.2.0.GA
Environment: Windows Vista, Firefox 2.0.0, Java 1.6u1, JBoss AS 4.0.5.GA, JBoss
Seam 1.2.1
Reporter: ROB b
Assigned To: Shane Bryzak
Fix For: 1.3.0.ALPHA
When a form post is processed by a MultipartRequest class and it has a field boundary
that occurs near the end of the internal buffer of the MultipartRequest class, it fails to
recognize the field boundary and interprets the field boundary and the following header to
be a part of the previous field's contents.
This bug can most easily be reproduced by creating a form of
enctype="multipart/form-data" with 30 <h:inputText> fields. The fields
should be submitted empty. This provides form post data with lots of field boundaries and
little in between. One of the field boundaries is likely to be near the end of the 2KB
class buffer. When the bug occurs, one of the blank fields will be shown to contain part
of the form boundary text. The form may have to be submitted 5 or 10 times, before the bug
occurs.
This same technique also occasionally causes the JBSEAM-1322 bug to occur (rarely,
though).
Sorry, I don't have a suggested fix. The class has been kind of hard for me to
debug.
Submitting the following XHTML source multiple times can be used to demonstrate the bug:
<!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
