kibitzing from Tom Lane. Large objects are now all stored in a single
system relation "pg_largeobject" --- no more xinv or xinx files, no more
relkind 'l'. This should offer substantial performance improvement for
large numbers of LOs, since there won't be directory bloat anymore.
It'll also fix problems like running out of locktable space when you
access thousands of LOs in one transaction.
Also clean up cruft in read/write routines. LOs with "holes" in them
(never-written byte ranges) now work just like Unix files with holes do:
a hole reads as zeroes but doesn't occupy storage space.
INITDB forced!
particular, allow linking with arbitrary commands rather than only $(AR) or
$(LD), and treat C++ without hacks.
Add option to disable shared libraries. This takes the place of the
BSD_SHLIB variable. The regression test driver ignores the plpgsql test
if there are no shared libraries available.
* Makefile: Add more standard targets. Improve shell redirection in GNU
make detection.
* src/backend/access/transam/rmgr.c: Fix incorrect(?) C.
* src/backend/libpq/pqcomm.c (StreamConnection): Work around accept() bug.
* src/include/port/unixware.h: ...with help from here.
* src/backend/nodes/print.c (plannode_type): Remove some "break"s after
"return"s.
* src/backend/tcop/dest.c (DestToFunction): ditto.
* src/backend/nodes/readfuncs.c: Add proper prototypes.
* src/backend/utils/adt/numutils.c (pg_atoi): Cope specially with strtol()
setting EINVAL. This saves us from creating an extra set of regression test
output for the affected systems.
* src/include/storage/s_lock.h (tas): Correct prototype.
* src/interfaces/libpq/fe-connect.c (parseServiceInfo): Don't use variable
as dimension in array definition.
* src/makefiles/Makefile.unixware: Add support for GCC.
* src/template/unixware: same here
* src/test/regress/expected/abstime-solaris-1947.out: Adjust whitespace.
* src/test/regress/expected/horology-solaris-1947.out: Part of this file
was evidently missing.
* src/test/regress/pg_regress.sh: Fix shell. mkdir -p returns non-zero if
the directory exists.
* src/test/regress/resultmap: Add entries for Unixware.
source directory. This involves mostly makefiles using $(srcdir) when they
might have used ".". (Regression tests don't work with this, yet.)
Sort out usage of CPPFLAGS, CFLAGS (and CXXFLAGS). Add "override" keyword
in most places, to preserve necessary flags even when the user overrode the
flags.
anywhere else that Makefile.shlib needs to modify CFLAGS to produce
valid code for a shared library. I'm not real clear on *why* the use
of override causes make to ignore the later attempt to assign
CFLAGS +=
but it indubitably does --- at least on gmake 3.79.1. gmake bug?
I prepared and tested a patch vs. 7.0.2, and it works fine. I've added
another option which allows users to have their own service file in
~/.pg_service.conf, which might come handy sometimes.

As a result, backend/libpq/pqcomm.c and interfaces/libpq/fe-connect.c
fail to compile.
The <netinet/tcp.h> header needs to be preceded by <netinet/in.h>, at
least on IRIX, Solaris and AIX. The simple configure test fails.
(That header on Linux is idempotent.)
The basic problem is that <netinet/tcp.h> is a BSD header. The
correct header for TCP internals such as TCP_NODELAY on a UNIX system
is <xti.h>. By UNIX I mean UNIX95 (aka XPG4v2 or SUSv1) or later.
The current UNIX standard (UNIX98 aka SUSv2) is available online at
<http://www.opengroup.org/onlinepubs/7908799/>.
The fix is to add header support for <xti.h> into configure.in and
config.h.in.
The 2 files which conditionally include <netinet/tcp.h> need also to
conditionally include <xti.h>.

couldn't produce a full patch using cvs diff -c this time since I have
created new files and anonymous cvs usage doesn't allow you to
adds. I'm supplying the modified src/interfaces/jdbc as a tarball at :
http://www.candleweb.no/~gunnar/projects/pgsql/postgres-jdbc-2000-10-05.tgz
The new files that should be added are :
? org/postgresql/PGStatement.java
? org/postgresql/ObjectPool.java
? org/postgresql/ObjectPoolFactory.java
There is now a global static pool of free byte arrays and used byte arrays
connected to a statement object. This is the role of the new PGStatement
class. Access to the global free array is synchronized, while we rely on
the PG_Stream synchronization for the used array.
My measurements show that the perfomance boost on this code is not quite as
big as my last shot, but it is still an improvement. Maybe some of the
difference is due to the new synchronization on the global array. I think I
will look into choosing between on a connection level and global level.
I have also started experimented with improving the performance of the
various conversions. The problem here is ofcourse related handle the
various encodings. One thing I found to speed up ResultSet.getInt() a lot
was to do custom conversion on the byte array into int instead of going
through the getString() to do the conversion. But I'm unsure if this is
portable, can we assume that a digit never can be represented by more than
one byte ? It works fine in my iso-latin-8859-1 environment, but what about
other environments ? Maybe we could provide different ResultSet
implementations depending on the encoding used or delegate some methods of
the result set to an "converter class".
Check the org/postgresql/jdbc2/FastResultSet.java in the tarball above to
see the modified getInt() method.

working on the VERY latest version of BeOS. I'm sure there will be
alot of comments, but then if there weren't I'd be disappointed!
Thanks for your continuing efforts to get this into your tree.
Haven't bothered with the new files as they haven't changed.
BTW Peter, the compiler is "broken" about the bool define and so on.
I'm filing a bug report to try and get it addressed. Hopefully then we
can tidy up the code a bit.
I await the replies with interest :)

have already modified "next_insert()" in 7.0-ecpglib. However
in the meaning of speed-up, the patch will be needed.

Update the installation instructions (formerly misnamed "FAQ"), add configure
checks for some headers rather than having users copy stubs manually (ugh!).
Use Autoconf check for exe extension. This also avoids inheriting the value
of $(X) from the environment.
illegal call to pg_mbclipen() that is for backend only. However I
have not remove the entire part of the problem, rather mark it with
#ifdef MULTIBYTE_NOTUSED since we should come back with a long range
solution someday.
add --without-tk option to disable Tk. We don't need the AC_PATH_XTRA
test because tkConfig.sh already contains all the information about how to
compile and link with X. Also make sure that libpq is up to date for
libpgtcl. Remove executable bits from pgaccess.sh, but add it to pgaccess.
DESTDIR=/else/where' and prepends the value of DESTDIR to the full
installation paths (e.g., /else/where/usr/local/pgsql/bin). This allows
users to install the package into a location different from the one that
was configured and hard-coded into various scripts, e.g., for creating
binary packages.
DESTDIR is in many cases preferrable over `make install
prefix=/else/where' because
a) `prefix' affects the path that is hard-coded into the files, which can
lead to a `make install prefix=xxx' (as done by the regression test
driver) corrupting the files in the source tree with wrong paths.
b) it doesn't work at all if a directory was overridden to not depend on
`prefix', e.g., --sysconfdir=/etc.
(Updating the regression test driver to use DESTDIR is a separate
undertaking.)

one-line change necessary. Due to the Mark Holloman "New Relkind for
Views" patch, my support for views in the driver will need to be updated
to match. The change to DatabaseMetaData.getTableTypes[][] is as
follows:
- {"VIEW", "(relkind='r' and relhasrules='t' and relname !~
'^pg_' and relname !~ '^xinv')"},
+ {"VIEW", "(relkind='v' and relname !~ '^pg_' and relname
!~ '^xinv')"},

carefully avoided installing the translations file in a controlled
environment here specifically to test for such a bug. :-)

This is a patch which lets the DatabaseMetaData return the object type
when getTables(....) is called. It does not really fix any bug, but it
fills in some functionality that should be there anyway. The diff
included here is off of the CVS as of just now :)

encountered while getting my reporting tool up and running with the
driver. All changes are in the DatabaseMetaData class.
Problem: The getDatabaseProductVersion() method was returning "6.5.2"
Resolution: Changed it to return "7.0.2"
Problem: A call to getTables() with an unsupported table type (in the
String array) resulted in a malformed SQL statement and subsequent
parsing error
Resolution: Unsupported table types are now ignored without error
Problem: In a getTables() call, tables and views were both returned by
the "TABLE" table type, and the "VIEW" table type was unsupported
Resolution: Changed the "TABLE" type to return only physical tables and
added support for the "VIEW" table type (returning only views)
Problem: The getIdentifierQuoteString() method was returning null
Resolution: This method now returns a double-quote
