* Tweak grammar to use FastAppend rather than lappend when constructingTom Lane2003-08-22
| | | | | expr_lists. This appears to be the only remaining O(N^2) bottleneck in processing many-way 'x IN (a,b,c,...)' conditions.
* Tweak processing of multiple-index-scan plans to reduce overhead whenTom Lane2003-08-22
| | | | | | | handling many-way scans: instead of re-evaluating all prior indexscan quals to see if a tuple has been fetched more than once, use a hash table indexed by tuple CTID. But fall back to the old way if the hash table grows to exceed SortMem.

* Improve dynahash.c's API so that caller can specify the comparison functionTom Lane2003-08-19
| | | | | | | | | | | | | as well as the hash function (formerly the comparison function was hardwired as memcmp()). This makes it possible to eliminate the special-purpose hashtable management code in execGrouping.c in favor of using dynahash to manage tuple hashtables; which is a win because dynahash knows how to expand a hashtable when the original size estimate was too small, whereas the special-purpose code was too stupid to do that. (See recent gripe from Stephan Szabo about poor performance when hash table size estimate is way off.) Free side benefit: when using string_hash, the default comparison function is now strncmp() instead of memcmp(). This should eliminate some part of the overhead associated with larger NAMEDATALEN values.
* When compiling a plpgsql trigger function, include the OID of the tableTom Lane2003-08-18
| | | | | | | | | the trigger is attached to in the hashkey. This ensures that we will create separate compiled trees for each table the trigger is used with, avoiding possible datatype-mismatch problems if the tables have different rowtypes. This is essentially the same bug recently identified in plpython --- though plpgsql doesn't seem as prone to crash when the rowtype changes underneath it. But failing robustly is no substitute for just working.
* Fix ARRAY[] construct so that in multidimensional case, elements canTom Lane2003-08-17
| | | | | | | | be anything yielding an array of the proper kind, not only sub-ARRAY[] constructs; do subscript checking at runtime not parse time. Also, adjust array_cat to make array || array comply with the SQL99 spec. Joe Conway
* Clean up locktable init code per recent gripe from Kurt Roeckx.Tom Lane2003-08-17
| | | | | No change in behavior, but old code would have failed to detect overrun of MAX_LOCKMODES.

* Create a 'type cache' that keeps track of the data needed for any particularTom Lane2003-08-17
| | | | | | | | | | | datatype by array_eq and array_cmp; use this to solve problems with memory leaks in array indexing support. The parser's equality_oper and ordering_oper routines also use the cache. Change the operator search algorithms to look for appropriate btree or hash index opclasses, instead of assuming operators named '<' or '=' have the right semantics. (ORDER BY ASC/DESC now also look at opclasses, instead of assuming '<' and '>' are the right things.) Add several more index opclasses so that there is no regression in functionality for base datatypes. initdb forced due to catalog additions.
* (I always forget what the magic numbers 0 through 2 means for theBruce Momjian2003-08-17
| | | | | | | | | | | | | "syslog" option.) By the way: The "virtual_host" parameter is a bad name for that particular option, I think. "Virtual host" signals that PostgreSQL will behave differently according to which IP address it's contacted (like Apache's virtual host support which makes the web-server serve different sites according to different criteria). A better word for the options would be "tcpip_listen_addr" or something like that. Troels Arvin

* libpq failed to cope with COPY FROM STDIN if the command was issuedTom Lane2003-08-13
| | | | | | | | | | via extended query protocol, because it sends Sync right after Execute without realizing that the command to be executed is COPY. There seems to be no reasonable way for it to realize that, either, so the best fix seems to be to make the backend ignore Sync during copy-in mode. Bit of a wart on the protocol, but little alternative. Also, libpq must send another Sync after terminating the COPY, if the command was issued via Execute.
* Add PQexecPrepared() and PQsendQueryPrepared() functions, to allowTom Lane2003-08-13
| | | | | | libpq users to perform Bind/Execute of previously prepared statements. Per yesterday's discussion, this offers enough performance improvement to justify bending the 'no new features during beta' rule.
* Move MemoryContextCheck() call from bottom of PostgresMain loop toTom Lane2003-08-13
| | | | | | just before CommitTransactionCommand(). This is a more sensible place to put it since commit discards a lot of contexts, and we'd not find out about stomps affecting only transaction-local contexts.
* I'm quite fond of doing VPATH builds, i.e. building outside the sourceBruce Momjian2003-08-13
| | | | | | | | | | tree. This also catches lots of little Makefile bugs, so here's a small patch for one of them (replacing an explicit reference to thread.c with a reference to it as the first prerequsite of the rule makes make look for it in the place where it was found (the source tree) rather than in the build tree.

* Include 'IPv4', 'IPv6', or 'Unix' in socket-creation failure messages,Tom Lane2003-08-12
| | | | | | in hopes of soothing fears of those with partial IPv6 support. Still an open question whether we should report EAFNOSUPPORT errors at all, though.
* Cope with NoData message from backend. Needed for case whereTom Lane2003-08-12
| | | | PQexecParams is used with a statement that doesn't return data.
* Marginal hacks to move some processing out of the per-client-messageTom Lane2003-08-12
| | | | | processing loop; avoids extra overhead when using parse/bind/execute messages instead of single Query message.
* Change some frequently-reached elog(DEBUG...) calls to ereport(DEBUG...)Tom Lane2003-08-12
| | | | | for speed reasons. (ereport falls out much more quickly when no output is needed than elog does.)
* Avoid unnecessary work when stats collection is disabled. TightenTom Lane2003-08-12

* Rewriter and planner should use only resno, not resname, to identifyTom Lane2003-08-11
| | | | | | | target columns in INSERT and UPDATE targetlists. Don't rely on resname to be accurate in ruleutils, either. This fixes bug reported by Donald Fraser, in which renaming a column referenced in a rule did not work very well.
* Applied patch from Oliver Jowett to better handle invalid input for getArrayBarry Lind2003-08-11

* Applied patch from Kim Ho to fix a regression against a 7.4 server. The resultBarry Lind2003-08-11
| | | | | | | | | | of transaction isolation level changed from uppercase to lower case between 7.3 and 7.4. In testing, a regression was also fixed in this area when talking to a 7.2 server due to changes in how notice messages are processed in the current code. Modified Files: jdbc/build.xml jdbc/org/postgresql/core/BaseStatement.java jdbc/org/postgresql/jdbc1/AbstractJdbc1Connection.java
* Code cleanup inspired by recent resname bug report (doesn't fix the bugTom Lane2003-08-11
| | | | | | | | yet, though). Avoid using nth() to fetch tlist entries; provide a common routine get_tle_by_resno() to search a tlist for a particular resno. This replaces a couple uses of nth() and a dozen hand-coded search loops. Also, replace a few uses of nth(length-1, list) with llast().
