c599a247bb Simplify lock manager data structures by making a clear separation between
the data defining the semantics of a lock method (ie, conflict resolution
table and ancillary data, which is all constant) and the hash tables
storing the current state.  The only thing we give up by this is the
ability to use separate hashtables for different lock methods, but there
is no need for that anyway.  Put some extra fields into the LockMethod
definition structs to clean up some other uglinesses, like hard-wired
tests for DEFAULT_LOCKMETHOD and USER_LOCKMETHOD.  This commit doesn't
do anything about the performance issues we were discussing, but it clears
away some of the underbrush that's in the way of fixing that.

0b36cb83dc PGXS should be set with := not =, as specified in the documentation,
to avoid useless multiple executions of pg_config.

8563ccae2c Simplify shared-memory lock data structures as per recent discussion:
it is sufficient to track whether a backend holds a lock or not, and
store information about transaction vs. session locks only in the
inside-the-backend LocalLockTable.  Since there can now be but one
PROCLOCK per lock per backend, LockCountMyLocks() is no longer needed,
thus eliminating some O(N^2) behavior when a backend holds many locks.
Also simplify the LockAcquire/LockRelease API by passing just a
'sessionLock' boolean instead of a transaction ID.  The previous API
was designed with the idea that per-transaction lock holding would be
important for subtransactions, but now that we have subtransactions we
know that this is unwanted.  While at it, add an 'isTempObject' parameter
to LockAcquire to indicate whether the lock is being taken on a temp
table.  This is not used just yet, but will be needed shortly for
two-phase commit.

140b078d2a Improve LockAcquire API per my recent proposal. All error conditions
are now reported via elog, eliminating the need to test the result code
at most call sites.  Make it possible for the caller to distinguish a
freshly acquired lock from one already held in the current transaction.
Use that capability to avoid redundant AcceptInvalidationMessages() calls
in LockRelation().

191b13aaca Factor out lock cleanup code that is needed in several places in lock.c.
Also, remove the rather useless return value of LockReleaseAll.  Change
response to detection of corruption in the shared lock tables to PANIC,
since that is the only way of cleaning up fully.
Originally an idea of Heikki Linnakangas, variously hacked on by
Alvaro Herrera and Tom Lane.

3a694bb0a1 Restructure LOCKTAG as per discussions of a couple months ago.
Essentially, we shoehorn in a lockable-object-type field by taking
a byte away from the lockmethodid, which can surely fit in one byte
instead of two.  This allows less artificial definitions of all the
other fields of LOCKTAG; we can get rid of the special pg_xactlock
pseudo-relation, and also support locks on individual tuples and
general database objects (including shared objects).  None of those
possibilities are actually exploited just yet, however.

I removed pg_xactlock from pg_class, but did not force initdb for
that change.  At this point, relkind 's' (SPECIAL) is unused and
could be removed entirely.

1785acebf2 Introduce local hash table for lock state, as per recent proposal.
PROCLOCK structs in shared memory now have only a bitmask for held
locks, rather than counts (making them 40 bytes smaller, which is a
good thing).  Multiple locks within a transaction are counted in the
local hash table instead, and we have provision for tracking which
ResourceOwner each count belongs to.  Solves recently reported problem
with memory leakage within long transactions.

fe548629c5 Invent ResourceOwner mechanism as per my recent proposal, and use it to
keep track of portal-related resources separately from transaction-related
resources.  This allows cursors to work in a somewhat sane fashion with
nested transactions.  For now, cursor behavior is non-subtransactional,
that is a cursor's state does not roll back if you abort a subtransaction
that fetched from the cursor.  We might want to change that later.

863aceb54f Get rid of PID entries in shmem hash table; there is no longer any need
for them, and making them just wastes time during backend startup/shutdown.

any reconfiguration/recompilation.

d8d9ed931e Add support to lock manager for conditionally locking a lock (ie,
return without waiting if we can't get the lock immediately).

558fae16e3 The attached patch enables the contrib subtree to build cleanly under
Cygwin with the possible exception of mSQL-interface.  Since I don't
have mSQL installed, I skipped this tool.

Except for dealing with a missing getopt.h (oid2name) and HUGE (seg),
the bulk of the patch uses the standard PostgreSQL approach to deal with
Windows DLL issues.

I tested the build aspect of this patch under Cygwin and Linux without
any ill affects.  Note that I did not actually attempt to test the code
for functionality.

The procedure to apply the patch is as follows:

    $ # save the attachment as /tmp/contrib.patch
    $ # change directory to the top of the PostgreSQL source tree
    $ patch -p0 </tmp/contrib.patch

6cc842abd3 Revise lock manager to support "session level" locks as well as "transaction
level" locks.  A session lock is not released at transaction commit (but it
is released on transaction abort, to ensure recovery after an elog(ERROR)).
In VACUUM, use a session lock to protect the master table while vacuuming a
TOAST table, so that the TOAST table can be done in an independent
transaction.

I also took this opportunity to do some cleanup and renaming in the lock
code.  The previously noted bug in ProcLockWakeup, that it couldn't wake up
any waiters beyond the first non-wakeable waiter, is now fixed.  Also found
a previously unknown bug of the same kind (failure to scan all members of
a lock queue in some cases) in DeadLockCheck.  This might have led to failure
to detect a deadlock condition, resulting in indefinite waits, but it's
difficult to characterize the conditions required to trigger a failure.

805e431a38 Add support for VPATH builds, that is, building somewhere else than in the
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.

74618e2b82 Another round of those unportable config/build changes :-/
* Add option to build with OpenSSL out of the box. Fix thusly exposed
  bit rot. Although it compiles now, getting this to do something
  useful is left as an exercise.

* Fix Kerberos options to defer checking for required libraries until
  all the other libraries are checked for.

* Change default odbcinst.ini and krb5.srvtab path to PREFIX/etc.

* Install work around for Autoconf's install-sh relative path anomaly.
  Get rid of old INSTL_*_OPTS variables, now that we don't need them
  anymore.

* Use `gunzip -c' instead of g?zcat. Reportedly broke on AIX.

* Look for only one of readline.h or readline/readline.h, not both.

* Make check for PS_STRINGS cacheable. Don't test for the header files
  separately.

* Disable fcntl(F_SETLK) test on Linux.

* Substitute the standard GCC warnings set into CFLAGS in configure,
  don't add it on in Makefile.global.

* Sweep through contrib tree to teach makefiles standard semantics.

... and in completely unrelated news:

* Make postmaster.opts arbitrary options-aware. I still think we need to
  save the environment as well.

a2226ad237 contrib-array.patch
this is an old patch which I have already submitted and never seen
        in the sources. It corrects the datatype oids used in some iterator
        functions. This bug has been reported to me by many other people.

contrib-datetime.patch

        some code contributed by Reiner Dassing <dassing@wettzell.ifag.de>

contrib-makefiles.patch

        fixes all my contrib makefiles which don't work with some compilers,
        as reported to me by another user.

contrib-miscutil.patch

        an old patch for one of my old contribs.

contrib-string.patch

        a small change to the c-like text output functions. Now the '{'
        is escaped only at the beginning of the string to distinguish it
        from arrays, and the '}' is no more escaped.

elog-lineno.patch

        adds the current lineno of CopyFrom to elog messages. This is very
        useful when you load a 1 million tuples table from an external file
        and there is a bad value somehere. Currently you get an error message
        but you can't know where is the bad data. The patch uses a variable
        which was declared static in copy.c. The variable is now exported
        and initialized to 0. It is always cleared at the end of the copy
        or at the first elog message or when the copy is canceled.
        I know this is very ugly but I can't find any better way of knowing
        where the copy fails and I have this problem quite often.

plperl-makefile.patch

        fixes a typo in a makefile, but the error must be elsewhere because
        it is a file generated automatically. Please have a look.

tprintf-timestamp.patch

        restores the original 2-digit year format, assuming that the two
        century digits don't carry much information and that '000202' is
        easier to read than 20000202. Being only a log file it shouldn't
        break anything.

Please apply the patches before the next scheduled code freeze.

I also noticed that some of the contribs don't compile correcly. Should we
ask people to fix their code or rename their makefiles so that they are
ignored by the top makefile?

27b8143944 Hi,
I have updated my contrib code for version 6.5. In the attachment you will
find the directories array, datetime, miscutil, string, tools and userlocks
which replace the corresponding directories under contrib.

In contrib/tools you will find some developement scripts which I use while
hacking the sources. I hope they will be useful for some other people.

I have also added a contrib/Makefile which tries to compile and install all
the contribs. Unfortunately many of them don't have a Makefile or don't
compile cleanly.

Here is a tar file the new directories, which substitute the old ones
in contrib. Please remove the old directories array, datetime, miscutil,
string and userlock before unpacking the tar file in contrib.

Note that as the modules are now installed in lib/modules I install all
my sql code in lib/sql. In my opinion also the other contributors should
follow these rules.
