From d99c818447ee4a68b762fb8a8c645ee6ef051ff9 Mon Sep 17 00:00:00 2001 From: Peter Eisentraut Date: Mon, 24 Jan 2022 16:13:21 +0100 Subject: [PATCH v4] Automatically generate node support functions Add a script to automatically generate the node support functions (copy, equal, out, and read, as well as the node tags enum) from the struct definitions. For each of the four node support files, it creates two include files, e.g., copyfuncs.inc1.c and copyfuncs.inc2.c, to include in the main file. All the scaffolding of the main file stays in place. TODO: In this patch, I have only ifdef'ed out the code to could be removed, mainly so that it won't constantly have merge conflicts. Eventually, that should all be changed to delete the code. When we do that, some code comments should probably be preserved elsewhere, so that will need another pass of consideration. I have tried to mostly make the coverage of the output match what is currently there. For example, one could now do out/read coverage of utility statement nodes, but I have manually excluded those for now. The reason is mainly that it's easier to diff the before and after, and adding a bunch of stuff like this might require a separate analysis and review. Subtyping (TidScan -> Scan) is supported. For the hard cases, you can just write a manual function and exclude generating one. For the not so hard cases, there is a way of annotating struct fields to get special behaviors. For example, pg_node_attr(equal_ignore) has the field ignored in equal functions.
