PK07733: CWXN CODEPAGE CONVERTS ORIGINAL DATA INSTEAD OF DATA RETURNED FROM THE ANALYZER.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Various errors may occur when the CICS analyzers calls DFHWBUN
  to unescape data received from a browser.  When the data is
  codepage converted it is taken from the buffer holding the
  original data received from the socket and not the buffer that
  was passed to the analyzer.  This means the unescaping changes
  are lost.

  ****************************************************************
  CICS receives data from a browser which contains escaped
  characters, in this case a space at the end of "signon" is
  escaped to a plus "+". The data is unescaped by DFHWBUN and
  saved into a buffer. When a request is made to codepage convert
  the data, instead of using this new buffer as input to the
  conversion, the original (escaped) buffer is used. This means
  that the data passed to the application contains escaped data
  causing unpredictable results. In this case the signon program
  DFHWBSN cannot find the requested function "signon " as it is
  suffixed with a plus sign instead of a space.

Problem conclusion

• DFHWBSR has been changed in routine
  wbrq_inbound_translate_user_data to allocate an intermediate
  buffer as input to the CONVERT_DATA call. The unescaped output
  from the analyser is copied into this buffer before the call. On
  return from the call this buffer is freemained. The data length
  wrb_user_data_length, is also updated after conversion.
