Subject: [HACKERS] linux/alpha patches
These patches lay the groundwork for a Linux/Alpha port. The port doesn't
actually work unless you tweak the linker to put all the pointers in the
first 32 bits of the address space, but it's at least a start. It
implements the test-and-set instruction in Alpha assembly, and also fixes
a lot of pointer-to-integer conversions, which is probably good anyway.

Subject: [HACKERS] equal column and table name patch
This fixes a bug where selects fail when there is a column with the same
name as the table it's a part of.

Subject: [HACKERS] better access control error messages
This patch replaces the 'no such class or insufficient privilege' with
distinct error messages that tell you whether the table really doesn't
exist or whether access was denied.

Subject: [HACKERS] backend Makefile patch
This patch cleans up backend/Makefile a little bit, and prevents it from
relinking the backend binary when no changes have been made.

Subject: [HACKERS] abort failed transaction patch
This patch allows you to end a transaction that has failed on an error
using the 'ABORT' statement without generating another error message.
(By default you get an error unless you use 'END' to terminate the
transaction, which has already been aborted anyway.)

not certain how to fix, so left them there and enabled -Wno-error for
this directory for now

${DATADIR}. The file is left as pg_geqo.sample, since, unlike
pg_hba.conf, it isn't a required file...but this way ppl know that
its there, and that its where it is required, if they choose to
use it

The following patch to src/backend/libpq/pqpacket.c provides additional
checking for bad packet length data. It was tested with the Linux telnet
client, with netcat using the numbers.txt and by dumping random numbers
into the port.
Patch by: Alvaro Martinez Echevarria <alvaro@lander.es>
Removed a reference to DATADIR that still existed
Patch from Massimo Dal Zotto <dz@cs.unitn.it>
The following patches add to the backend a new debugging flag -K which prints
a debug trace of all locking operations on user relations (those with oid
greater than 20000). The code is compiled only if LOCK_MGR_DEBUG is defined,
so the patch should be harmless if not explicitly enabled.
I'm using the code to trace deadlock conditions caused by application queries
using the command "$POSTMASTER -D $PGDATA -o '-d 1 -K 1'.
The patches are for version 6.0 dated 970126.
Make sure we have an irix port

What looks like some *major* improvements to btree indexing...
Patches from: aoki@CS.Berkeley.EDU (Paul M. Aoki)
i gave jolly my btree bulkload code a long, long time ago but never
gave him a bunch of my bugfixes. here's a diff against the 6.0
baseline.
for some reason, this code has slowed down somewhat relative to the
insertion-build code on very small tables. don't know why -- it used
to be within about 10%. anyway, here are some (highly unscientific!)
timings on a dec 3000/300 for synthetic tables with 10k, 100k and
1000k tuples (basically, 1mb, 10mb and 100mb heaps). 'c' means
clustered (pre-sorted) inputs and 'u' means unclustered (randomly
ordered) inputs. the 10k table basically fits in the buffer pool, but
the 100k and 1000k tables don't. as you can see, insertion build is
fine if you've sorted your heaps on your index key or if your heap
fits in core, but is absolutely horrible on unordered data (yes,
that's 7.5 hours to index 100mb of data...) because of the zillions of
random i/os.
if it doesn't work for you for whatever reason, you can always turn it
back off by flipping the FastBuild flag in nbtree.c. i don't have
time to maintain it.
good luck!

Assign priorities when creating jobs in lock queue.
Add comment for questionable 5 padding.
Fix \? syntax for copy command.
Remove machine.h, since it wasn't doing anything that config.h wasn't
already doing
Removed only reference to a machine.h I could find in c.h, to win32/machine.h
Try to further reduce the PORT dependencies.
Essentially, config.h now includes an 'os.h', which is created via
configure by linking a "port.h" file from the port directory to the
include directory.
Going to try to merge backend/port in similar ways
Remove NO_{SIGPROCMASK,SETSID,WAITPID} from nextstep port, since they
aren't doing anything anyway
Changes to configure/config.h.in to check for:
sigprocmask, setsid and waitpid
Especially for nextstep systems
Awaiting for a context diff from Gregor to complete changes for the nextstep
port
Various fixes suggested by Gregor Hoffleit
Add a check to configure for strdup
Remove all the '-ltermcap' checks from psql/Makefile
Have {psql,pg_dump}/Makefile modified if strdup doesn't exist on the system
|I took a look at this and I think pg_dump mishandles arrays of ints and floats
|by neglecting to quote them.
|
|I have made a minor change to pg_dump.c that will fix this.
|
|Dates are dumped and restored OK with pg_dump in V6
|
|We'll still need to fix the dump in both cases if the original dump is from V1.09.
