Move exprType(), exprTypmod(), expression_tree_walker(), and related routines
into nodes/nodeFuncs, so as to reduce wanton cross-subsystem #includes inside the backend. There's probably more that should be done along this line, but this is a start anyway.

Steps to Add a Node

-------------------
|
||||
|
||||
Suppose you wana define a node Foo:
|
||||
Suppose you wanna define a node Foo:
|
||||
|
||||
1. add a tag (T_Foo) to the enum NodeTag in nodes.h (You may have to
|
||||
recompile the whole tree after doing this.)
|
||||
2. add the structure definition to the appropriate ???nodes.h file. If you
|
||||
intend to inherit from, say a Plan node, put Plan as the first field of
|
||||
you definition.
|
||||
3. if you intend to use copyObject, equal, nodeToString or stringToNode,
|
||||
1. Add a tag (T_Foo) to the enum NodeTag in nodes.h. (If you insert the
|
||||
tag in a way that moves the numbers associated with existing tags,
|
||||
you'll need to recompile the whole tree after doing this. It doesn't
|
||||
force initdb though, because the numbers never go to disk.)
|
||||
2. Add the structure definition to the appropriate include/nodes/???.h file.
|
||||
If you intend to inherit from, say a Plan node, put Plan as the first field
|
||||
of your struct definition.
|
||||
3. If you intend to use copyObject, equal, nodeToString or stringToNode,
|
||||
add an appropriate function to copyfuncs.c, equalfuncs.c, outfuncs.c
|
||||
and readfuncs.c accordingly. (Except for frequently used nodes, don't
|
||||
bother writing a creator function in makefuncs.c)
|
||||
and readfuncs.c accordingly. (Except for frequently used nodes, don't
|
||||
bother writing a creator function in makefuncs.c) The header comments
|
||||
in those files give general rules for whether you need to add support.
|
||||
4. Add cases to the functions in nodeFuncs.c as needed. There are many
|
||||
other places you'll probably also need to teach about your new node
|
||||
type. Best bet is to grep for references to one or two similar existing
|
||||
node types to find all the places to touch.
|
||||
|
||||
|
||||
Historical Note
|
||||
---------------
|
||||
|
||||
Prior to the current simple C structure definitions, the Node structures
|
||||
uses a pseudo-inheritance system which automatically generates creator and
|
||||
accessor functions. Since every node inherits from LispValue, the whole thing
|
||||
is a mess. Here's a little anecdote:
|
||||
used a pseudo-inheritance system which automatically generated creator and
|
||||
accessor functions. Since every node inherited from LispValue, the whole thing
|
||||
was a mess. Here's a little anecdote:
|
||||
|
||||
LispValue definition -- class used to support lisp structures
|
||||
in C. This is here because we did not want to totally rewrite
|
||||
planner and executor code which depended on lisp structures when
|
||||
we ported postgres V1 from lisp to C. -cim 4/23/90
