Tom Lane 7a3693716d Reimplement hash index locking algorithms, per my recent proposal to 
pghackers.  This fixes the problem recently reported by Markus KrÌutner
(hash bucket split corrupts the state of scans being done concurrently),
and I believe it also fixes all the known problems with deadlocks in
hash index operations.  Hash indexes are still not really ready for prime
time (since they aren't WAL-logged), but this is a step forward.

Peter Eisentraut ee4ae6ceb2 Add note that a for loop where the lower bound is greater than the upper 
bound is valid but does nothing.

Tom Lane 5ac2d7c0eb In _bt_check_unique() loop, don't bother applying _bt_isequal() to 
killed items; just skip to the next item immediately.  Only check for
key equality when we reach a non-killed item or the end of the index
page.  This saves key comparisons when there are lots of killed items,
as for example in a heavily-updated table that's not been vacuumed lately.
Seems to be a win for pgbench anyway.

Peter Eisentraut 30b4abf5d0 Remove outdated CLI things. 2003-09-02 21:45:37 +00:00
Tom Lane b916cc435a Cause standalone backend (including bootstrap case) to read the GUC 
config file if it exists.  This was already discussed as being a good
idea, and now seems the cleanest way to deal with initdb-time failures
on machines with small SHMMAX.  (The submitted patches instead modified
initdb.sh to pass the correct sizing parameters, but that would still
leave standalone backends prone to failure later.  An admin who needs
to use a standalone backend has enough trouble already, he shouldn't
have to manually configure its shmem settings...)

Tom Lane d70610c4ee Several fixes for hash indexes that involve changing the on-disk index 
layout; therefore, this change forces REINDEX of hash indexes (though
not a full initdb).  Widen hashm_ntuples to double so that hash space
management doesn't get confused by more than 4G entries; enlarge the
allowed number of free-space-bitmap pages; replace the useless bshift
field with a useful bmshift field; eliminate 4 bytes of wasted space
in the per-page special area.

Tom Lane 8b2450c831 Fix a couple typos, add some more comments. 2003-09-02 03:29:01 +00:00
Tom Lane 39673ca47b Rewrite hashbulkdelete() to make it amenable to new bucket locking 
scheme.  A pleasant side effect is that it is *much* faster when deleting
a large fraction of the indexed tuples, because of elimination of
redundant hash_step activity induced by hash_adjscans.  Various other
continuing code cleanup.

Peter Eisentraut 5f65345a57 Do not pass server_encoding to the client. 
libpq, talking to an old server, should assume SQL_ASCII as the default
client encoding, because that is what the server will actually use (not
the server encoding).

Peter Eisentraut f10a9033bf Clean up after pygresql removal: adjust/remove documentation and remove 
unneeded configure work.
 2003-09-01 23:01:49 +00:00
Tom Lane 65c2d427fb Preliminary cleanup for hash index code (doesn't attack the locking problem 
yet).  Fix a couple of bugs that would only appear if multiple bitmap pages
are used, including a buffer reference leak and incorrect computation of bit
indexes.  Get rid of 'overflow address' concept, which accomplished nothing
except obfuscating the code and creating a risk of failure due to limited
range of offset field.  Rename some misleadingly-named fields and routines,
and improve documentation.
 2003-09-01 20:26:34 +00:00
Tom Lane eaeb8621f8 Add some internals documentation for hash indexes, including an 
explanation of the remarkably confusing page addressing scheme.
The file also includes my planned-but-not-yet-implemented revision
of the hash index locking scheme.
