Hi,

Seems like you can't use "uint" on windows, it fails trying to compile this:

  typedef struct xl_xact_commit
  {
  	TimestampTz xact_time;		/* time of commit */
+ 	int			slotId;			/* slotId in procarray */
+ 	uint		xinfo;			/* info flags */

The error message is:
"""
gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement
 -Wendif-labels -fno-strict-aliasing -fwrapv -g
-I../../../../src/include -I./src/include/port/win32 -DEXEC_BACKEND
"-I../../../../src/include/port/win32" -DBUILDING_DLL  -c -o heapam.o
heapam.c -MMD -MP -MF .deps/heapam.Po
In file included from heapam.c:50:
../../../../src/include/access/xact.h:109: error: syntax error before "uint"
../../../../src/include/access/xact.h:109: warning: no semicolon at
end of struct or union
../../../../src/include/access/xact.h:117: error: syntax error before '}' token
../../../../src/include/access/xact.h:117: warning: type defaults to
`int' in declaration of `xl_xact_commit'
../../../../src/include/access/xact.h:117: warning: data definition

"""
I was able to compile changing uint for uint32 but i'm not sure if
that is the aproppiate type...

* [PATCH 1/8] Use tuple slot to pass tuples for rewriting.
@ 2026-06-16 11:54  Antonin Houska <ah@cybertec.at>
  0 siblings, 0 replies; 19+ messages in thread

From: Antonin Houska @ 2026-06-16 11:54 UTC (permalink / raw)

This patch tries to adopt the preferable way of handling tuples, i.e. pass the
containing tuple slot rather than the actual tuple. The motivation is that
heap_insert_for_repack() will need a slot in the near future, in order to call
ExecInsertIndexTuples(). Also, in order to set values of dropped attributes to
to NULL, it seems more compact to pass a tuple slot as a workspace than two
arrays (one for values and one for nulls).
