Here's the patch I promised over on HACKERS - it alters the implementation of '\e' history tracking for systems that have a readline compatability library without replace_history_entry. I fall back to pushing the query onto the history stack after the \e, rather than replacing it. The patch adds one more place to look for readline headers, and a test for replace_history_entry. I've only included the patch for configure.in Ross J. Reedstrom

The heralded `Grand Unified Configuration scheme' (GUC) That means you can now set your options in either or all of $PGDATA/configuration, some postmaster option (--enable-fsync=off), or set a SET command. The list of options is in backend/utils/misc/guc.c, documentation will be written post haste. pg_options is gone, so is that pq_geqo config file. Also removed were backend -K, -Q, and -T options (no longer applicable, although -d0 does the same as -Q). Added to configure an --enable-syslog option. changed all callers from TPRINTF to elog(DEBUG)

Allow maximum number of backends to be set at configure time (--with-maxbackends). Add a postmaster switch (-N backends) that allows the limit to be reduced at postmaster start time. (You can't increase it, sorry to say, because there are still some fixed-size arrays.) Grab the number of semaphores indicated by min(MAXBACKENDS, -N) at postmaster startup, so that this particular form of bogus configuration is exposed immediately rather than under heavy load.

Version number now set in configure, available through Makefile.global and config.h. Adjusted all referring code. Scrapped pg_version and changed initdb accordingly. Integrated src/utils/version.c into src/backend/utils/init/miscinit.c. Changed all callers. Set version number to `7.1devel'. (Non-numeric version suffixes now allowed.)

Support alternate storage scheme of 64-bit integer for date/time types. Use "--enable-integer-datetimes" in configuration to use this rather than the original float8 storage. I would recommend the integer-based storage for any platform on which it is available. We perhaps should make this the default for the production release. Change timezone(timestamptz) results to return timestamp rather than a character string. Formerly, we didn't have a way to represent timestamps with an explicit time zone other than freezing the info into a string. Now, we can reasonably omit the explicit time zone from the result and return a timestamp with values appropriate for the specified time zone. Much cleaner, and if you need the time zone in the result you can put it into a character string pretty easily anyway. Allow fractional seconds in date/time types even for dates prior to 1BC. Limit timestamp data types to 6 decimal places of precision. Just right for a micro-second storage of int8 date/time types, and reduces the number of places ad-hoc rounding was occuring for the float8-based types. Use lookup tables for precision/rounding calculations for timestamp and interval types. Formerly used pow() to calculate the desired value but with a more limited range there is no reason to not type in a lookup table. Should be *much* better performance, though formerly there were some optimizations to help minimize the number of times pow() was called. Define a HAVE_INT64_TIMESTAMP variable. Based on the configure option "--enable-integer-datetimes" and the existing internal INT64_IS_BUSTED. Add explicit date/interval operators and functions for addition and subtraction. Formerly relied on implicit type promotion from date to timestamp with time zone. Change timezone conversion functions for the timetz type from "timetz()" to "timezone()". This is consistant with other time zone coersion functions for other types. Bump the catalog version to 200204201. Fix up regression tests to reflect changes in fractional seconds representation for date/times in BC eras. All regression tests pass on my Linux box.

Here is the patch with memory leak checker. This checker allow detect in-chunk leaks, overwrite-next-chunk leaks and overwrite block-freeptr leaks. A in-chunk leak --- if something overwrite space after wanted (via palloc() size, but it is still inside chunk. For example x = palloc(12); /* create 16b chunk */ memset(x, '#', 13); this leak is in the current source total invisible, because chunk is 16b and leak is in the "align space". For this feature I add data_size to StandardChunk, and all memory which go from AllocSetAlloc() is marked as 0x7F. The MemoryContextCheck() is compiled '#ifdef USE_ASSERT_CHECKING'. I add this checking to 'tcop/postgres.c' and is active after each backend query, but it is probably not sufficient, because some MemoryContext exist only during memory processing --- will good if someone who known where it is needful (Tom:-) add it for others contexts; A problem in the current source is that we have still some malloc() allocation that is not needful and this allocation is total invisible for all context routines. For example Dllist in backend (pretty dirty it is in catcache where values in Dllist are palloc-ed, but list is malloc-ed). --- and BTW. this Dllist design stand in the way for query cache :-) Tom, if you agree I start replace some mallocs. BTW. --- Tom, have you idea for across transaction presistent allocation for SQL functions? (like regex - now it is via malloc) I almost forget. I add one if() to AllocSetAlloc(), for 'size' that are greater than ALLOC_BIGCHUNK_LIMIT is not needful check AllocSetFreeIndex(), because 'fidx' is always 'ALLOCSET_NUM_FREELISTS - 1'. It a little brisk up allocation for very large chunks. Right? Karel

I use this prefix , when configure ask me for "Additional directories to search for include files" . ( because there a conflict in the header when you compile psql.c ) In this case, you must permut the sequence of directive -I . Erwan MAS

The attached patch corrects two problems with autoconfiguration of psql in Postgres 6.3.2. Both of these problems were complained of recently in pgsql-questions: 1. In the right circumstances, psql.c will fail to compile due to trying to include a nonexistent <history.h>. (Thread "Compile-time error" around 17 Apr 98.) 2. In other circumstances, psql will compile but does not provide command history capability, even though the underlying readline library supports it. (Various threads, most recently "query repetition in psql" around 29 Apr.) Tom Lane

Move substitute extern declarations to end of file, so that they are not read until after we've read the port-specific header file. In particular this should make it safer to #include system headers for inet_aton; in general it seems that the port header file ought to be in a position to set definitions before we do stuff based on having a definition or not.

Substituted new configure test for types of accept() Interfaced a lot of the custom tests to the config.cache, in the process made them separate macros and grouped them out into files.

Adrian Hall reported a problem to me that snprintf() doesn't exist in, at least, Solaris 2.5.1. We use it in backend/utils/adt/int8.c. Add a check to configure so that we see if it exists or not, and, if not, compile in snprintf.c from backend/port, which was taken from, and falls under the same Berkeley license as us, the FreeBSD libc/stdio ...

The attached patch enables PostgreSQL CVS to build cleanly under Cygwin when built against readline 4.2. Specifically, it handles the deprecation of filename_completion_function() with preference for rl_filename_completion_function() Although, I was motivated by Cygwin support, IMO this patch is appropriate for all platforms. To quote from the readline source: #if 0 /* Backwards compatibility (compat.c). These will go away sometime. */ ... extern READLINE_EXPORT(char, *filename_completion_function) ... #endif Note that this patch is modeled after the one by Peter Eisentraut for completion_matches(): http://www.ca.postgresql.org/~petere/readline42.html I tested this patch under the following environments: Cygwin with readline 4.1 Cygwin with readline 4.2 Linux with readline 2.2.1 Linux with readline 4.2 and it behaved as expected.

/* Define if you have strtoull() */
Add configure checks for strtoll, strtoull (or strto[u]q). Disable 'long long int' portions of ecpg if the type or these functions don't exist.

Add configure-time check whether sig_atomic_t is defined; if not, provide a default definition equating it to 'int'. Should trigger only on machines with pre-ANSI-C header files, eg SunOS 4.1.x.

/* Define if the corresponding types are defined in standard headers */
More correct way to check for existence of types, which allows to specify which include files to consider. Should fix BeOS problems with int8 types.

Create an internal semaphore API that is not tied to SysV semaphores. As proof of concept, provide an alternate implementation based on POSIX semaphores. Also push the SysV shared-memory implementation into a separate file so that it can be replaced conveniently.

Rearrange config.h entries into a more sensible order, and add some documentation. Let's try to keep this file a bit neater in future, hmm? Also (to get back to the original point) update info about FUNC_MAX_ARGS, and add additional config symbols for debugging new memory management changes.

Move substitute extern declarations to end of file, so that they are not read until after we've read the port-specific header file. In particular this should make it safer to #include system headers for inet_aton; in general it seems that the port header file ought to be in a position to set definitions before we do stuff based on having a definition or not.

libpq++/pgconnection.h must not include postgres_fe.h, else it fails to compile in client apps that use the standard installed header set. To allow removing that include, move DLLIMPORT definitions out of c.h and into the appropriate port-specific header files.
