This change adds a script to programatically group all includes in a
specific order. The script was used as a one time invocation to group
and sort all includes throught our formatted code. The grouping is as
follows:
- System includes (eg. `#include<...>`)
- Postgres.h (eg. `#include "postgres.h"`)
- Toplevel imports from postgres, not contained in a directory (eg.
`#include "miscadmin.h"`)
- General postgres includes (eg . `#include "nodes/..."`)
- Toplevel citus includes, not contained in a directory (eg. `#include
"citus_verion.h"`)
- Columnar includes (eg. `#include "columnar/..."`)
- Distributed includes (eg. `#include "distributed/..."`)
Because it is quite hard to understand the difference between toplevel
citus includes and toplevel postgres includes it hardcodes the list of
toplevel citus includes. In the same manner it assumes anything not
prefixed with `columnar/` or `distributed/` as a postgres include.
The sorting/grouping is enforced by CI. Since we do so with our own
script there are not changes required in our uncrustify configuration.
Citus build with PG16 fails because of the following warnings:
- using char* instead of Datum
- using pointer instead of oid
- candidate function for format attribute
- remove old definition from PG11 compatibility 62bf571ced
This commit fixes the above.
This fixes 3 bugs:
1. `strtoul` never underflows, so that branch was useless
2. `strtoul` has ULONG_MAX instead of LONG_MAX when it overflows
3. `long` and `unsigned long` are not necessarily 64bit, they can be
either more or less. So now `strtoll` and `strtoull` are used
and 64 bit bounds are checked.
