Tom Lane	08be00fabe	Fix plpython's handling of functions used as triggers on multiple tables. ... plpython tried to use a single cache entry for a trigger function, but it needs a separate cache entry for each table the trigger is applied to, because there is table-dependent data in there. This was done correctly before 9.1, but commit 46211da1b8 broke it by simplifying the lookup key from "function OID and triggered table OID" to "function OID and is-trigger boolean". Go back to using both OIDs as the lookup key. Per bug report from Sandro Santilli. Andres Freund	13 years ago
Alvaro Herrera	c219d9b0a5	Split tuple struct defs from htup.h to htup_details.h ... This reduces unnecessary exposure of other headers through htup.h, which is very widely included by many files. I have chosen to move the function prototypes to the new file as well, because that means htup.h no longer needs to include tupdesc.h. In itself this doesn't have much effect in indirect inclusion of tupdesc.h throughout the tree, because it's also required by execnodes.h; but it's something to explore in the future, and it seemed best to do the htup.h change now while I'm busy with it.	14 years ago

Tom Lane	5cd72c7a7c	Patch some corner-case bugs in pl/python. ... Dave Malcolm of Red Hat is working on a static code analysis tool for Python-related C code. It reported a number of problems in plpython, most of which were failures to check for NULL results from object-creation functions, so would only be an issue in very-low-memory situations. Patch in HEAD and 9.1. We could go further back but it's not clear that these issues are important enough to justify the work. Jan Urbański	14 years ago
Tom Lane	ed75380bda	Create a stack of pl/python "execution contexts". ... This replaces the former global variable PLy_curr_procedure, and provides a place to stash per-call-level information. In particular we create a per-call-level scratch memory context. For the moment, the scratch context is just used to avoid leaking memory from datatype output function calls in PLyDict_FromTuple. There probably will be more use-cases in future. Although this is a fix for a pre-existing memory leakage bug, it seems sufficiently invasive to not want to back-patch; it feels better as part of the major rearrangement of plpython code that we've already done as part of 9.2.

Peter Eisentraut	147c248254	Split plpython.c into smaller pieces ... This moves the code around from one huge file into hopefully logical and more manageable modules. For the most part, the code itself was not touched, except: PLy_function_handler and PLy_trigger_handler were renamed to PLy_exec_function and PLy_exec_trigger, because they were not actually handlers in the PL handler sense, and it makes the naming more similar to the way PL/pgSQL is organized. The initialization of the procedure caches was separated into a new function init_procedure_caches to keep the hash tables private to plpy_procedures.c. Jan Urbański and Peter Eisentraut	14 years ago
