* Endeavor to make pgstats buffer process (a) safe and (b) useful.Tom Lane2001-08-05
| | | | | | | | Make sure it exits immediately when collector process dies --- in old code, buffer process would hang around and compete with the new buffer process for packets. Make sure it doesn't block on writing the pipe when the collector falls more than a pipeload behind. Avoid leaking pgstats FDs into every backend.
* Remove no-longer-needed fcntl call (I'm not sure it *ever* did anythingTom Lane2001-08-05

* This patch is because Hurd does not support NOFILE. It is against currentBruce Momjian2001-08-04
| | | | | | | | | | | | cvs. The Debian bug report says, "The upstream source makes use of NOFILE unconditionalized. As the Hurd doesn't have an arbitrary limit on the number of open files, this is not defined. But _SC_OPEN_MAX works fine and returns 1024 (applications can increase this as they want), so I suggest the below diff. Please forward this upstream, too." Oliver Elphick

* Attached is a patch that does the following:Bruce Momjian2001-08-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) improves performance of commit/rollback by reducing number of round trips to the server 2) uses 7.1 functionality for setting the transaction isolation level 3) backs out a patch from 11 days ago because that code failed to compile under jdk1.1 Details: 1) The old code was doing the following for each commit: commit begin set transaction isolation level xxx thus a call to commit was performing three round trips to the database. The new code does this in one round trip as: commit; begin; set transaction isolation level xxx In a simple test program that performs 1000 transactions (where each transaction does one simple select inside that transaction) has the following before and after timings: Client and Server on same machine old new --- --- 1.877sec 1.405sec 25.1% improvement Client and Server on different machines old new --- --- 4.184sec 2.927sec 34.3% improvement (all timings are an average of four different runs) 2) The driver was using 'set transaction isolation level xxx' at the begining of each transaction, instead of using the new 7.1 syntax of 'set session characteristics as transaction isolation level xxx' which only needs to be done once instead of for each transaction. This is done conditionally (i.e. if server is 7.0 or older do the old behaviour, else do the new behaviour) to not break backward compatibility. This also required the movement of some code to check/test database version numbers from the DatabaseMetaData object to the Connection object. 3) Finally while testing, I discovered that the code that was checked in 11 days ago actually didn't compile. The code in the patch for Connection.setCatalog() used Properties.setProperty() which only exists in JDK1.2 or higher. Thus compiling the JDBC1 driver failed as this method doesn't exist. Thus I backed out that patch. Barry Lind
* Fix handling of SIGCHLD, per recent pghackers discussion: on someTom Lane2001-08-04
| | | | | | | platforms system(2) gets confused unless the signal handler is set to SIG_DFL, not SIG_IGN. pgstats.c now uses pqsignal() as it should, not signal(). Also, arrange for the stats collector process to show a reasonable ID in 'ps', rather than looking like a postmaster.
* Fix residual breakage from Windows socket-errno patch: the routinesTom Lane2001-08-03
| | | | that should use regular errno, not WSAGetLastError(), now do so again.
* Fix win32.mak to support MULTIBYTE build --- it was pulling in severalTom Lane2001-08-03
| | | | | backend files that it shouldn't anymore, causing compile failures. Per report from Darko Prenosil.
* For some reason, CREATE TYPE has only accepted alignment specificationsTom Lane2001-08-03
| | | | | of 'int4' and 'double'. Add 'char' and 'int2' to allow user-defined types to access the full set of supported alignments.
* Fix pg_dump so that comments on views are dumped in the proper sequence.Tom Lane2001-08-03
| | | | | | | | | Dump the alignment and storage information for user-defined types (how'd that manage to slip through the cracks?), and don't dump 'shell' types that don't have typisdefined set. Fix badly broken logic for dependencies of type definitions (did not work for more than one user-defined type...). Avoid memory leakage within pg_dump by being more careful to release storage used by PQExpBuffer objects.
* Clean up various memory leaks within plpgsql, and re-enable theTom Lane2001-08-02
| | | | | | | | exec_eval_simple_expr shortcut, which was diked out in 7.1 because it leaked too much space. CVS tip now leaks no memory in Chris Ruprecht's example, which formerly leaked to the tune of 500 MB. (Much of this is work that Jan already did; this commit just cleans up around the edges.)
* Add a SPI_copytupledesc function that parallels SPI_copytuple --- ie,Tom Lane2001-08-02
| | | | | it copies the tupdesc into upper-executor memory. This is necessary for returning tuple descriptors without leaking all of lower exec memory.

* Fix some poor decisions about sizing of trigger-related memory contexts.Tom Lane2001-08-02

* I noticed that pltcl didn't have any way to get to SPI_lastoid like plpgsql ↵Bruce Momjian2001-08-02
| | | | | | | | | | | | | | | | | does.. I started using pltcl a lot because I like to decide when and how my queries get planned.. so I put one together really quick Sorry I don't have the original around to make a quick diff, but its a very small change... I think this should be in the next release, there's no reason not to have it. its a function with no expected arguments, so you can use it like: spi_exec "INSERT INTO mytable(columns...) VALUES(values..)" set oid [spi_lastoid] spi_exec "SELECT mytable_id from mytable WHERE oid=$oid" It just didn't make sense for me to use plpgsql and pltcl, or just screw them both and use SPI from C. bob@redivi.com
* Even though SO_PEERCRED is probably totally unportable, might as wellTom Lane2001-08-02
| | | | | declare the getsockopt parameter as ACCEPT_TYPE_ARG3 to be consistent with our other uses of getsockopt.
* Remove SO_PASSCRED step in ident_unix --- according to Helge Bahmann,Tom Lane2001-08-02
| | | | | | that call is not needed to prepare for SO_PEERCRED. Also, simplify code so that #ifdef SO_PEERCRED appears in only one place, to make it easier to support other platforms with variants of this capability.
* Digging through previous discussion of this patch, I note where Peter E.Tom Lane2001-08-01
| | | | | | points out how silly it is to use Autoconf to test for a preprocessor symbol, when one can equally easily #ifdef on the symbol itself. Accordingly, revert configure to prior state and do it that way.
* Support ident authentication on local (Unix) socket connections, if theTom Lane2001-08-01
| | | | | | system supports SO_PEERCRED requests for Unix sockets. This is an amalgamation of patches submitted by Helge Bahmann and Oliver Elphick, with some editorializing by yours truly.

* Cleanup code for preparsing pg_hba.conf and pg_ident.conf. Store lineTom Lane2001-07-31
| | | | | | | | | number in the data structure so that we can give at least a minimally useful idea of where the mistake is when we issue syntax error messages. Move the ClientAuthentication() call to where it should have been in the first place, so that postmaster memory releasing can happen in a reasonable place also. Update obsolete comments, correct one real bug (auth_argument was not picked up correctly).
* Further thought shows that has_distinct_on_clause() needs to take muchTom Lane2001-07-31
| | | | | | | | more care with resjunk tlist entries than it was doing. The original coding ignored resjunk entries entirely, but a resjunk entry that is in either the distinctClause or sortClause lists indicates that DISTINCT ON was used. It's important for ruleutils.c to get this right, else we may dump views using DISTINCT ON incorrectly.
* Fix optimizer to not try to push WHERE clauses down into a sub-SELECT thatTom Lane2001-07-31
| | | | | | has a DISTINCT ON clause, per bug report from Anthony Wood. While at it, improve the DISTINCT-ON-clause recognizer routine to not be fooled by out- of-order DISTINCT lists.

* Change SQL commands embedded in the initdb script from the styleTom Lane2001-07-31
| | | | | | | | | | | | | | | echo "command" | postgres to the style postgres <<EOF command EOF This makes the script more legible (IMHO anyway) by reducing the need to escape quotes, and allows us to execute successive SQL commands in a single standalone-backend run, rather than needing to start a new standalone backend for each command. With all the CREATE VIEWs that are getting done now, this makes for a rather substantial reduction in the runtime of initdb. (Some of us do initdb often enough to care how long it runs ;-).)
* This patch merges the identical methods from the JDBC1 and JDBC2Bruce Momjian2001-07-30
| | | | | | | | | | | | connection implementations (org.postgresql.jdbc[1|2].Connection) into their superclass (org.postgresql.Connection). It also changes the close() methods of Connection and PG_Stream, so that PG_Stream no longer is responsible for sending the termination packet 'X' to the backend. I figured that protocol-level stuff like that belonged in Connection more than in PG_Stream. Anders Bengtsson

* Arrange for GRANT/REVOKE on a view to be dumped at the right time,Tom Lane2001-07-29

* JDBC encoding additions.Bruce Momjian2001-07-21

* i've spotted a following problem using DBD::Pg under win32. winsockBruce Momjian2001-07-20
| | | | | | | | | functions do not set errno, so some normal conditions are treated as fatal errors. e.g. fetching large tuples fails, as at some point recv() returns EWOULDBLOCK. here's a patch, which replaces errno with WSAGetLastError(). i've tried to to affect non-win32 code. Dmitry Yurtaev

* Arrange to recycle old XLOG log segment files as new segment files,Tom Lane2001-07-19
| | | | | | | | | | | | | | rather than deleting them only to have to create more. Steady state is 2*CHECKPOINT_SEGMENTS + WAL_FILES + 1 segment files, which will simply be renamed rather than constantly deleted and recreated. To make this safe, added current XLOG file/offset number to page header of XLOG pages, so that an un-overwritten page from an old incarnation of a logfile can be reliably told from a valid page. This change means that if you try to restart postmaster in a CVS-tip database after installing the change, you'll get a complaint about bad XLOG page magic number. If you don't want to initdb, run contrib/pg_resetxlog (and be sure you shut down the old postmaster cleanly).
