* Clean up non-reentrant interface for hash_seq/HashTableWalk, so thatTom Lane2001-01-02
| | | | | | | | starting a new hashtable search no longer clobbers any other search active anywhere in the system. Fix RelationCacheInvalidate() so that it will not crash or go into an infinite loop if invoked recursively, as for example by a second SI Reset message arriving while we are still processing a prior one.
* Tweak temporary-installation setup so that it doesn't break when theTom Lane2001-01-02

* Ensure attcacheoff is written out as -1 when writing pg_attributeTom Lane2001-01-01

* Don't say 'export PGHOST' or 'export PGPORT' unless we actually defineTom Lane2000-12-31

* On further thought, we need a defense against empty PGPORT here too.Tom Lane2000-12-31

| | | | when using vendor cc, not gcc.
* Clean up spinlock assembly code slightly (just cosmetic improvements)Tom Lane2000-12-30
| | | | | | | | | for Alpha gcc case. For Alpha non-gcc case, replace use of __INTERLOCKED_TESTBITSS_QUAD builtin with __LOCK_LONG_RETRY and __UNLOCK_LONG. The former does not execute an MB instruction and therefore was guaranteed not to work on multiprocessor machines. The LOCK_LONG builtins produce code that is the same in all essential details as the gcc assembler code.
* Paranoia about possible values of errno after a shmget/semget failure.Tom Lane2000-12-30
| | | | | | In theory we should always get EEXIST if there's a key collision, but if the kernel code tests error conditions in a weird order, perhaps EACCES or EIDRM could occur too.
* Remove obsolete and unportable enable_plpgsql script. createlang hasTom Lane2000-12-30

| | | | | | | assume that TAS() will always succeed the first time, even if the lock is known to be free. Also, make sure that code will eventually time out and report a stuck spinlock, rather than looping forever. Small cleanups in s_lock.h, too.

* Attached are patches for two fixes to reduce memory usage by the JDBCBruce Momjian2000-12-28
| | | | | | | | | | | | | | | | | | | | | | | | drivers. The first fix fixes the PreparedStatement object to not allocate unnecessary objects when converting native types to Stings. The old code used the following format: (new Integer(x)).toString() whereas this can more efficiently be occompilshed by: Integer.toString(x); avoiding the unnecessary object creation. The second fix is to release some resources on the close() of a ResultSet. Currently the close() method on ResultSet is a noop. The purpose of the close() method is to release resources when the ResultSet is no longer needed. The fix is to free the tuples cached by the ResultSet when it is closed (by clearing out the Vector object that stores the tuples). This is important for my application, as I have a cache of Statement objects that I reuse. Since the Statement object maintains a reference to the ResultSet and the ResultSet kept references to the old tuples, my cache was holding on to a lot of memory. Barry Lind

* Let's try this again on accepting the correct range of Oid input valuesTom Lane2000-12-28
| | | | for 64-bit platforms ...
* Fix portability problems recently exposed by regression tests on Alphas.Tom Lane2000-12-27
| | | | | | | | | | 1. Distinguish cases where a Datum representing a tuple datatype is an OID from cases where it is a pointer to TupleTableSlot, and make sure we use the right typlen in each case. 2. Make fetchatt() and related code support 8-byte by-value datatypes on machines where Datum is 8 bytes. Centralize knowledge of the available by-value datatype sizes in two macros in tupmacs.h, so that this will be easier if we ever have to do it again.
* Improve comments.Tom Lane2000-12-23

* Compute reasonable cost and output-row-count estimates for LIMIT planTom Lane2000-12-23
| | | | nodes.
* Replace overly-cute coding with code that (a) has defined behaviorTom Lane2000-12-23
| | | | | according to the ANSI C spec, (b) gets the boundary conditions right, and (c) is about a third as long and three times more intelligible.
* Small cleanup of temp-table handling. Disallow creation of a non-tempTom Lane2000-12-22
| | | | | | | table that inherits from a temp table. Make sure the right things happen if one creates a temp table, creates another temp that inherits from it, then renames the first one. (Previously, system would end up trying to delete the temp tables in the wrong order.)
* Repair not-too-well-thought-out code to do rangechecking of OIDs onTom Lane2000-12-22
| | | | 64-bit machines. Also, make oidvectorin use the same code as oidin.
* Avoid XLogFlush for clean buffers in BufferSync.Vadim B. Mikheev2000-12-22

* Improve error message for case where DROP TABLE is rejected becauseTom Lane2000-12-22
| | | | table has a child table.
* Add 'ONLY' to queries generated by RI triggers, so as to preserve pre-7.1Tom Lane2000-12-22
| | | | | semantics of RI operations. Eventually we ought to look at making RI work properly across inheritance trees, but not for 7.1 ...
* Change default output formatting for CIDR to be unabbreviated, perTom Lane2000-12-22
| | | | | | recommendation from Paul Vixie. Add a new abbrev() function to produce abbreviated format as text. No forced initdb, but new function is not available unless you do an initdb or add the pg_proc row manually.
* - Fixed bug in a connect statement using varchars.Michael Meskes2000-12-22
| | | | - Synced parser.
* Fix PQsetdbLogin() backward compatibility problem.Tatsuo Ishii2000-12-22
| | | | | | | | | | | | If pghost == "" and pgport == "" then PQsetdbLogin() fails with a error message: Is the postmaster running locally and accepting connections on Unix socket '/tmp/.s.PGSQL.0'? I see many applications such as PHP fails due to this behavior. Now if pgport == "", then it is assumed to be a DEF_PGPORT_STR. This is the same behavior as the version prior 7.1.
* Clean up CREATE TYPE/OPERATOR/AGGREGATE productions, so that parserTom Lane2000-12-22
| | | | will not accept types named with operator names or vice versa.
* In looking at the 7.1beta1 code for JDBC, I noticed that support wasBruce Momjian2000-12-22
| | | | | | | | | | | | | | | added to support character set encodings. However I noticed that the encoding that is used isn't obtained from the DB. Since Java uses unicode UCS2 internally the character set encoding is used to translate strings from/to the DB encoding. So it seems logical that the code would get the encoding from the DB instead of the current method of requiring the user pass it as a parameter. Attached is a patch that gets the DB encoding from the DB in the same manner as is done in libpq/fe-connect.c. The patch is created off of the latest CVS sources (Connection.java version 1.10). Barry Lind
* Revise lock manager to support "session level" locks as well as "transactionTom Lane2000-12-22
| | | | | | | | | | | | | | | | 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.
* Repair round(numeric) function. An initdb would be required to get thePeter Eisentraut2000-12-21
| | | | fixed version, otherwise you'll continue to encounter breakage.
* Fix longstanding bug with VIEW using BETWEEN: OffsetVarNodes would getTom Lane2000-12-21
| | | | | | applied to the duplicated subtree twice. Probably someday we should fix the parser not to generate multiple links to the same subtree, but for now a quick copyObject() is the path of least resistance.
