Tom Lane	0426f349ef	Rearrange the handling of error context reports. ... Remove the code in plpgsql that suppressed the innermost line of CONTEXT for messages emitted by RAISE commands. That was never more than a quick backwards-compatibility hack, and it's pretty silly in cases where the RAISE is nested in several levels of function. What's more, it violated our design theory that verbosity of error reports should be controlled on the client side not the server side. To alleviate the resulting noise increase, introduce a feature in libpq and psql whereby the CONTEXT field of messages can be suppressed, either always or only for non-error messages. Printing CONTEXT for errors only is now their default behavior. The actual code changes here are pretty small, but the effects on the regression test outputs are widespread. I had to edit some of the alternative expected outputs by hand; hopefully the buildfarm will soon find anything I fat-fingered. In passing, fix up (again) the output line counts in psql's various help displays. Add some commentary about how to verify them.

Tom Lane	8b6010b835	Improve support for composite types in PL/Python. ... Allow PL/Python functions to return arrays of composite types. Also, fix the restriction that plpy.prepare/plpy.execute couldn't handle query parameters or result columns of composite types. In passing, adopt a saner arrangement for where to release the tupledesc reference counts acquired via lookup_rowtype_tupdesc. The callers of PLyObject_ToCompositeDatum were doing the lookups, but then the releases happened somewhere down inside subroutines of PLyObject_ToCompositeDatum, which is bizarre and bug-prone. Instead release in the same function that acquires the refcount. Ed Behn and Ronan Dunklau, reviewed by Abhijit Menon-Sen	12 years ago
Peter Eisentraut	527ea66849	PL/Python: Adjust the regression tests for Python 3.3 ... Similar to 2cfb1c6f77, the order in which dictionary elements are printed is not reliable. This reappeared in the tests of the string representation of result objects. Reduce the test case to one result set column so that there is no question of order.	13 years ago
Peter Eisentraut	330ed4ac6c	PL/Python: Add result object str handler ... This is intended so that say plpy.debug(rv) prints something useful for debugging query execution results. reviewed by Steve Singer	13 years ago
Peter Eisentraut	a97207b690	PL/Python: Fix slicing support for result objects for Python 3 ... The old way of implementing slicing support by implementing PySequenceMethods.sq_slice no longer works in Python 3. You now have to implement PyMappingMethods.mp_subscript. Do this by simply proxying the call to the wrapped list of result dictionaries. Consolidate some of the subscripting regression tests. Jan Urbański	14 years ago
Peter Eisentraut	e6c2e8cb87	PL/Python: Improve test coverage ... Add test cases for inline handler of plython2u (when using that language name), and for result object element assignment. There is now at least one test case for every top-level functionality, except plpy.Fatal (annoying to use in regression tests) and result object slice retrieval and slice assignment (which are somewhat broken).	14 years ago
Peter Eisentraut	0f48e06751	PL/Python: Improve documentation of nrows() method ... Clarify that nrows() is the number of rows processed, versus the number of rows returned, which can be obtained using len. Also add tests about that.	14 years ago
Peter Eisentraut	c03523ed3f	PL/Python: Fix crash when colnames() etc. called without result set ... The result object methods colnames() etc. would crash when called after a command that did not produce a result set. Now they throw an exception. discovery and initial patch by Jean-Baptiste Quenot	14 years ago
Peter Eisentraut	ee7fa66b19	PL/Python: Add result metadata functions ... Add result object functions .colnames, .coltypes, .coltypmods to obtain information about the result column names and types, which was previously not possible in the PL/Python SPI interface. reviewed by Abhijit Menon-Sen	14 years ago
Peter Eisentraut	89e850e6fd	plpython: Add SPI cursor support ... Add a function plpy.cursor that is similar to plpy.execute but uses an SPI cursor to avoid fetching the entire result set into memory. Jan Urbański, reviewed by Steve Singer	14 years ago
Peter Eisentraut	3f11971916	Remove extra newlines at end and beginning of files, add missing newlines ... at end of files.	16 years ago
Peter Eisentraut	2e3b16c8ba	Improve PL/Python elog output ... When the elog functions (plpy.info etc.) get a single argument, just print that argument instead of printing the single-member tuple like ('foo',).	16 years ago
Peter Eisentraut	983d10833e	Use generic attribute management in PL/Python ... Switch the implementation of the plan and result types to generic attribute management, as described at <http://docs.python.org/extending/newtypes.html>. This modernizes and simplifies the code a bit and prepares for Python 3.1, where the old way doesn't work anymore.	17 years ago
Peter Eisentraut	5dff93638c	Make PL/Python tests more compatible with Python 3 ... This changes a bunch of incidentially used constructs in the PL/Python regression tests to equivalent constructs in cases where Python 3 no longer supports the old syntax. Support for older Python versions is unchanged.	17 years ago
Peter Eisentraut	9d9848668f	Split the plpython regression test into test cases arranged by topic, instead ... of the previous monolithic setup-create-run sequence, that was apparently inherited from a previous test infrastructure, but makes working with the tests and adding new ones weird.	17 years ago
