all local buffers @ xact commit, so accordingly nextFreeLocalBuf
is first local buffer now.
It helps to avoid unnecessary local buffer allocations in LocalBufferAlloc()
latter ("memmory leaks" in 'order by').
2. ResetLocalBufferPool() lost allocated local buffers:
memset(LocalBufferDescriptors, 0, sizeof(BufferDesc) * NLocBuffer);
(local buffers leak @ xact aborts).
Here are the latest changes to the INSTALL instructions.
The main changes are:
- Step 5, on flex
- Steps 18 and 19, on regression tests
- Step 22 c) on starting postmaster on bootup on FreeBSD
- Added porting notes for SPARC/Linux at end.
If there is time, Thomas should review step 19.
Bring optional new-storage date and time up to date and test.
This new storage format should fix the "Sparc gcc -O2 bug".
(Enable new code with USE_NEW_DATE and USE_NEW_TIME in dt.h)
Subject: [PATCHES] Patch for INSTALL
The following patch makes a number of modifications to file INSTALL.
Among other things, it restores some platform specific notes I deleted.
It also no longer requires a separate compile for the regression tests.
Please note that this patch already incorporates the patch Hal Snyder
submitted on Monday. Do not apply Hal's patch.
Subject: [PORTS] minor fix for DGUX port
src/include/port/dgux.h needs the following three lines appended:
#ifndef BYTE_ORDER
#define BYTE_ORDER BIG_ENDIAN
#endif
I believe this to be correct for DG/UX on M88k processors. I don't have one of
the new Intel-based boxes to check on.
Include some additional path functions which were coded but omitted here.
Add translation and rotation/scaling operators for some geometric types.
Fix bugs in some geometry comparison operator declarations.
Add type conversion functions for floating point numbers.
Check for zero in unary minus floating point code (IEEE allows an
explicit negative zero which looks ugly in a query result!).
Ensure circle type has non-negative radius.
