** Name: cus_trmwhite - Trim trailing white space.
**
** Description:
** Used by the parser facility for trimming trailing white space
** in character texts residing in memory. The text may be null terminated
** but doesn't have to be. This is the reason why the length argument
** is passed along with the buffer pointer. This routine is currently
** only used in calls to psf_error to make text presented to recipients
** of error messages more user friendly.
**
** Inputs:
** len Max length to be scanned for white space
** bufp Pointer to the buf holding char data
** (does not have to be null terminated)
** Outputs:
** Returns:
** Length Length of non-white part of the string
**
** Exceptions:
** None.
**
** Side Effects:
** None.
**
** History:
** 11-apr-87 (stec)
** written
** 16-apr-87 (stec)
** changed a little.
** Addressed performance and Kanji issues.
** 02-may-1990 (fred)
** Revamped to trim trailing white space from an arbitrary string.
** Previously, it was assumed that trailing white space started
** with the first bit o' white space from the beginning. The routine
** will now trim from the end back. This was necessitated for BLOB
** support which is the first case of a datatype name with an embedded
** blank (standard name - 'long varchar').
** 25-mar-93 (rickh)
** Moved here from PSFTRMWH.C and renamed with a cuf prefix.

** Name: psq_parseqry - Parse a query and return a data structure
**
** INTERNAL PSF call format: status = psq_parseqry(&psq_cb, &sess_cb);
**
** EXTERNAL call format: status = psq_call(PSQ_PARSEQRY, &psq_cb, &sess_cb);
**
** Description:
** This function will parse a query in QSF memory. It will return a
** data structure (such as a query tree), and a code telling what kind of
** query was just parsed (e.g. a copy statement). This code will be
** called the "query mode". For qrymod definitions, it will store a
** modified version of the query text in QSF, for later insertion in the
** iiqrytext system relation.
**
** This function will check the syntax of each statement, and will perform
** some semantic validations. The syntax checking will be rather simple:
** each statement will either be right or wrong, and a syntax error will
** cause the whole go block to be aborted. Semantic checks will be more
** complicated; some of them will cause warnings (which will allow the
** statement to continue), and some will cause errors (causing the
** statement to be aborted). It should be noted that the semantic checks
** will not be the same in the Jupiter version as in previous versions;
** in the Jupiter version, for instance, the parser won't check for whether
** the statement is valid inside a multi-query transaction.
**
** Sometimes it will be found that the definition of a view, permit, or
** integrity is out of date. When this happens, this function will return
** an error status saying so, and an id for finding the query text in the
** iiqrytext relation, so that the definition can be re-parsed and
** re-stored. Accordingly, this function has an option by which one can
** tell it to get the query text out of the iiqrytext relation instead of
** QSF.
**
** When a statement is parsed that creates a new cursor, the parser will
** assign a cursor id to the cursor, create a cursor control block
** containing information about the cursor, and return the cursor id inside
** with the query tree representing the cursor. This cursor id will be
** used throughout the session to uniquely identify the cursor. When a
** "close cursor" statement is parsed, the parser will deallocate the
** control block associated with the cursor.
**
** The parser will automatically apply view, permit, and integrity
** processing to any data manipulation query it parses. This will not
** require a separate call to the parser.
**
** Multi-statement go blocks are no longer allowed, as they used to be in
** previous versions. This parser can handle only one statement at a time.
**
** Inputs:
** psq_cb
** .psq_qid A unique identifier for getting the
** query text from QSF.
** .psq_iiqrytext TRUE means to get the query text from
** the iiqrytext relation, not QSF.
** .psq_txtid Query text id key into iiqrytext
** relation; used only if above is true.
** sess_cb Pointer to the session control block
**
** Outputs:
** psq_cb
** .psq_qlang The language of the query text.
** .psq_mode The query mode (a code telling what
** kind of query was just parsed).
** .psq_result QSF id for the data structure produced
** (query tree, or control block stored as
** QEP).
** .psq_txtid Query text id key into iiqrytext
** relation; filled in if some qrymod
** object needs redefining.
** .psq_mnyfmt Set on a "set money_format" or
** "set money_prec" statement
** .psq_dtefmt Set on a "set date_format" statement
** .psq_decimal Set on a "set decimal" statement
** .psq_error Standard error block
** E_PS0000_OK Success
** E_PS0001_USER_ERROR Mistake by user
** E_PS0002_INTERNAL_ERROR Internal inconsistency inside PSF
** E_PS0B01_OUTDATED_VIEW View out of date; must re-define
** E_PS0B02_OUTDATED_PERMIT Permit out of date; must re-define
** E_PS0B03_OUTDATED_INTEG Integrity out of date; must re-def.
** E_PS0B04_CANT_GET_TEXT Can't get query text
** .psq_txtout QSF id for the create procedure stmt to
** be stored in the system catalog.
**
** Returns:
** E_DB_OK Function completed normally.
** E_DB_WARN Function completed with warning(s)
** E_DB_ERROR Function failed; non-catastrophic error
** E_DB_FATAL Function failed; catastrophic error
** Exceptions:
** none
**
** Side Effects:
** Stores query tree or control block in QSF.
** Can open a cursor.
**
** History:
** 01-oct-85 (jeff)
** written
** 19-sep-86 (daved)
** end of qry should point to last char. This char should be a space.
** this makes the scanner's job easier
** 27-jan-87 (daved)
** add the printqry set command.
** 02-oct-87 (stec)
** Removed pss_journaling flag initialization;
** must be initialized in psqbgnses.c
** 19-jan-88 (stec)
** Changed initialization od pst_resloc.
** 25-may-88 (stec)
** Made changes in connection with DB procedures.
** QSF object of QP type has to be destroyed if
** translate_or_define worked for CREATE PROCEDURE.
** 23-aug-88 (stec)
** Initialize qso_handle in QSO_OBIDs in psq_cb.
** 21-apr-89 (neil)
** Extracted some initialization (psq_cbinit) from psq_parseqry to
** allow it to be called from other routines as well.
** 11-dec-89 (ralph)
** Change interface to QSO for dbprocs
** 12-sep-90 (teresa)
** fix faulty pss_retry logic.
** 15-jun-92 (barbara)
** Sybil merge. Pass in sess control block to pst_clrrng.
** 23-nov-92 (barbara)
** For Star, accept range statement as the one and only allowable
** QUEL statement. This is to support old FE's which use the range
** statement as a quick way to ascertain table existence. FEs of
** >= 6.5 vintage use a table_resolve() function, so at some point
** we can remove the QUEL range table statement support for Star.
** 24-nov-92 (ralph)
** CREATE SCHEMA:
** Initialize pss_prvgoval
** 22-dec-92 (rblumer)
** clean up after pss_tchain2 just like pss_tchain.
** 25-may-93 (rog)
** Move clean-up/exit code into psq_cbreturn() and then call it.
** 11-oct-93 (swm)
** Bug #56448
** Declared trbuf for psf_display() to pass to TRformat.
** TRformat removes `\n' chars, so to ensure that psf_scctrace()
** outputs a logical line (which it is supposed to do), we allocate
** a buffer with one extra char for NL and will hide it from TRformat
** by specifying length of 1 byte less. The NL char will be inserted
** at the end of the message by psf_scctrace().
** 16-mar-94 (andre)
** if performing an internal PSF retry and trace point ps129 (same as
*8 SET PRINTQRY) is set, instead of redisplaying the query we will
*8 tell the user that we are retrying the last query.
** 28-feb-2005 (wanfr01)
** Bug 64899, INGSRV87
** Add stack overflow handler for TRU64.
** 17-mar-06 (dougi)
** Init pss_hintcount to 0 for optimizer hints project.
** 23-june-06 (dougi)
** Init pss_stmtno to 1 for procedure debugging.
** 05-sep-06 (toumi01)
** Init pss_stmtno to 0 (to match new "help procedure" numbering)
** lest we point, PC register like, to the _following_ statement.
** 15-Sep-2008 (kibro01) b120571
** Use same session ID as available in iimonitor
** 16-Sep-2008 (kibro01) b120571
** Remove compilation error from cast of sessid
** 16-Feb-2009 (kibro01) b121674
** Add version to SESSION BEGINS message in sc930 and give out
** data type of parameters.
** 10-Jul-2009 (kibro01) b122299
** Increase the version number due to dates being printed out now.
** 15-Jul-2009 (kibro01) b122172
** Change QUERY or QUEL to REQUERY or REQUEL when a DB procedure is
** reparsed due to being invalidated.
** 23-Jul-2009 (kibro01) b122172
** Separate the print_qry_buffer logic to avoid stack size problems.
** 3-Aug-2009 (kibro01) b122393
** Use print_qry_buffer_ptr to avoid inlining.
** 4-Aug-2009 (kibro01) b122172
** Allow REQUERY/REQUEL through even if the RECREATE flag is set so
** we get the useful debug output.
** 28-Oct-2009 (maspa05) b122725
** ult_print_tracefile now uses integer constants instead of string
** for type parameter - SC930_LTYPE_PARM instead of "PARM" and so on
** Also moved function definitions for SC930 tracing to ulf.h
** The functions involved were - ult_always_trace, ult_open_tracefile

** Description: Add a piece of text to the text chain for a repeat query. It is

** uniform fashion so that comparing two stored query texts would
** serve as a reliable indicator of their sameness. Each piece
** will be preceeded with a blank except for a PERIOD. Neither the
** piece consisting of PERIOD nor the following piece will be
** preceeded with a blank.
**
** Inputs:
** header Pointer to chain header
** piece Pointer to piece of text
** size Size of piece
** result Place to put pointer to new piece
** err_blk Filled in if an error happens
**
** Outputs:
** result Filled in with pointer to chain element
** err_blk Filled in if an error happens
** Returns:
** E_DB_OK Success
** E_DB_ERROR Non-catastrophic failure
** E_DB_FATAL Catastrophic failure
** Exceptions:
** none
**
** Side Effects:
** Allocates memory
**
** History:
** 24-jan-90 (andre)
** Plagiarized from psq_tadd().
** 28-jan-91 (andre)
** Do not insert a space if a piece is immediately following a piece
** consisting of a $.
