+# gdbpg.py contains scripts to nicely print the postgres datastructures
+# while in a gdb session. Since the vscode debugger is based on gdb this

+# to understand the internal datastructures we are working with.
+source /root/gdbpg.py

+# when debugging postgres it is convenient to _always_ have a breakpoint
+# trigger when an error is logged. Because .gdbinit is sourced before gdb
+# is fully attached and has the sources loaded. To make sure the breakpoint
+# is added when the library is loaded we temporary set the breakpoint pending
+# to on. After we have added out breakpoint we revert back to the default
+# configuration for breakpoint pending.
+# The breakpoint is hard to read, but at entry of the function we don't have
+# the level loaded in elevel. Instead we hardcode the location where the
+# level of the current error is stored. Also gdb doesn't understand the
+# ERROR symbol so we hardcode this to the value of ERROR. It is very unlikely
+# this value will ever change in postgres, but if it does we might need to
+# find a way to conditionally load the correct breakpoint.

+break elog.c:errfinish if errordata[errordata_stack_depth].elevel == 21

+echo when attaching to a postgres backend a breakpoint will be set on elog.c:errfinish \n
+echo it will only break on errors being raised in postgres \n
+echo \n
+echo to disable this breakpoint from vscode run `-exec disable 1` in the debug console \n
+echo this assumes it's the first breakpoint loaded as it is loaded from .gdbinit \n
+echo this can be verified with `-exec info break`, enabling can be done with \n
+echo `-exec enable 1` \n

 This script prints stack traces for failed tests, if they left core files.

+## `sort_and_group_includes.sh`
+
+This script checks and fixes issues with include grouping and sorting in C files.
+
+Includes are grouped in the following groups:
+ - System includes (eg. `#include <math>`)
+ - Postgres.h include (eg. `#include "postgres.h"`)
+ - Toplevel postgres includes (includes not in a directory eg. `#include "miscadmin.h`)
+ - Postgres includes in a directory (eg. `#include "catalog/pg_type.h"`)
+ - Toplevel citus includes (includes not in a directory eg. `#include "pg_version_constants.h"`)
+ - Columnar includes (eg. `#include "columnar/columnar.h"`)
+ - Distributed includes (eg. `#include "distributed/maintenanced.h"`)
+
+Within every group the include lines are sorted alphabetically.
