Jürgen Keil updated AXIS2-5448:
-------------------------------
Attachment: test.c
Makefile
bug_date.xsd
bug_date.xml
bug_date.wsdl
sh $a2c/bin/tools/wsdl2c/WSDL2C.sh -uri bug_date.wsdl -d adb -u -S bug_date
test.c can be used to parse bug_date.xml to C structures.
> WSDL2C: sporadic failures in deserializer code generated for xs:date, returns

> Key: AXIS2-5448
> URL: https://issues.apache.org/jira/browse/AXIS2-5448
> Project: Axis2
> Issue Type: Bug
> Components: adb, codegen
> Affects Versions: 1.6.2
> Environment: iOS 5.1 or MacOS X 10.7.5
> Reporter: Jürgen Keil
> Attachments: bug_date.wsdl, bug_date.xml, bug_date.xsd, Makefile,
> test.c

> The xml deserializer code generated for xs:date calls
> axutil_date_time_deserialize_date_time()
> instead of axutil_date_time_deserialize_date() to convert a date from string
> format (e.g. "2012-09-30")
> to a axutil_date_time_t.
> This results in random failures parsing the date. The deserialized date
> sometimes contains the current date instead of the date value that was
> present in the xml data.
> How does it fail in axutil_date_time_deserialize_date_time() ? It fails
> because:
> - A wrong sscanf format string is used to parse the date, sscanf is unable to
> fill all arguments. sscanf returns 3, and
> axutil_date_time_deserialize_date_time() does not recognize this failure.
> - after that, axutil_date_time_deserialize_date_time() accesses
> uninitialized variables for "hour",
> "min", and "sec", and may randomly return parse errors, because hour, min,
> sec contain a value that is out of range. The end result is that sometimes
> no parsed date is written to the deserialized date, and we get the current
> date instead.
> In the debugger, we have this:
> (gdb) bt
