Tom Lane ebfc56d3fb Handle impending sinval queue overflow by means of a separate signal 
(SIGUSR1, which we have not been using recently) instead of piggybacking
on SIGUSR2-driven NOTIFY processing.  This has several good results:
the processing needed to drain the sinval queue is a lot less than the
processing needed to answer a NOTIFY; there's less contention since we
don't have a bunch of backends all trying to acquire exclusive lock on
pg_listener; backends that are sitting inside a transaction block can
still drain the queue, whereas NOTIFY processing can't run if there's
an open transaction block.  (This last is a fairly serious issue that
I don't think we ever recognized before --- with clients like JDBC that
tend to sit with open transaction blocks, the sinval queue draining
mechanism never really worked as intended, probably resulting in a lot
of useless cache-reset overhead.)  This is the last of several proposed
changes in response to Philip Warner's recent report of sinval-induced
performance problems.

Tom Lane 4d86ae4260 For multi-table ANALYZE, use per-table transactions when possible 
(ie, when not inside a transaction block), so that we can avoid holding
locks longer than necessary.  Per trouble report from Philip Warner.
 2004-05-22 23:14:38 +00:00
Tom Lane e26c403fd0 Reduce pg_listener lock taken by NOTIFY et al from AccessExclusiveLock 
to ExclusiveLock.  This still serializes the operations of this module,
but doesn't conflict with concurrent ANALYZE operations.  Per trouble
report from Philip Warner a few weeks ago.

Tom Lane 323a45099a Fix to install correctly in vpath build case. 2004-05-22 21:02:32 +00:00
Tom Lane b1ea9811b3 Fix for vpath builds. 2004-05-22 02:15:08 +00:00
Tom Lane 4fb9aa43f6 Clean up failure to remove exec.o on 'make clean'. 2004-05-22 02:14:28 +00:00
Tom Lane 3983869439 Use wide-character library routines, if available, for upper/lower/initcap 
functions.  This allows these functions to work correctly with Unicode and
other multibyte encodings.  Per prior discussion.

Also, revert my earlier change to move installation path mashing from
Makefile.global to configure.  Turns out not to work well because configure
script is working with unexpanded variables, and so fails to match in
cases where it should match.

Tom Lane add8b70dda Handle inclusion of port modules 'correctly', viz the same way libpq 
does it.  Fixes OS X, which needs path.c.  It may be that Win32 needs
some more port modules, but they are easily added.
 2004-05-21 21:56:02 +00:00
Tom Lane d584db6086 pgindent did a pretty awful job on the timezone code, particularly with 
respect to doubly-starred comment blocks.  Do some manual cleanup.
 2004-05-21 20:59:10 +00:00
Tom Lane 13f96c4b6b Put path configuration information into a .h file instead of cluttering 
several different module Makefiles with it.  Also, do any adjustment
of installation paths during configure, rather than every time Makefile.global
is read.

Tom Lane 748a15a8ea Probably need sys/time.h here too to be safe. 2004-05-21 16:22:38 +00:00
Tom Lane e6319d1d28 Put back #include <sys/time.h> in files that seem to need it on Linux. 2004-05-21 16:08:47 +00:00
Tom Lane ff0b706b13 Fix random breakage in exec.c for platforms where strdup is a macro. 2004-05-21 16:06:23 +00:00
Michael Meskes 79c3bf4984 - Fixed DEALLOCATE PREPARE to use correct function call 
- Made sure connect statement does not accept single char variable,
  but only strings.
 2004-05-21 13:50:12 +00:00
Bruce Momjian 0a19fb42c2 Pgindent timezone file, per request from Tom. 2004-05-21 12:30:25 +00:00
Tom Lane 63bd0db121 Integrate src/timezone library for all platforms. There is more we can 
and should do now that we control our own destiny for timezone handling,
but this commit gets the bulk of the picayune diffs in place.
Magnus Hagander and Tom Lane.

Bruce Momjian 260b513fc3 Add mention of why -lpgport is needed in ecpglib (dllwrap). 2004-05-21 03:12:03 +00:00
Bruce Momjian 928e73ea62 Add -lpgport to ecpglib link only on win32. Other platforms have 
problems with it.
 2004-05-21 03:10:47 +00:00
Tom Lane 9bfee3adee Revert addition of -lpgport, which breaks the build on platforms that 
are sticky about non-PIC code in shared libraries.  Windows will have
to find another solution (probably similar to the way libpq does it).
 2004-05-21 00:14:38 +00:00
Tom Lane 7d717f2471 Rename static variables to avoid possible name conflicts on systems with 
dirty standard headers (eg AIX).
 2004-05-20 17:13:52 +00:00

Bruce Momjian ceceeffe1e Clean up find_my_exec to work cleaner. 
Add Win32 code to look in the current directory before the path.

Add code so memory is allocated using palloc in backend object files.
 2004-05-20 15:35:41 +00:00
Tom Lane 868404b859 Fix speling. 2004-05-20 15:07:30 +00:00

Bruce Momjian 163e72aa60 Add $libdir to mingw and cygwin for installcheck too. 2004-05-20 00:21:36 +00:00
Tom Lane 29fcd22080 Improve error reporting behavior in parse_hba(): give more complete 
error report for getaddrinfo failures, point at correct token for syntax
errors in all cases, don't log redundant messages.
 2004-05-19 22:06:16 +00:00
Bruce Momjian 178c08d0c7 Rename another irix file. 2004-05-19 21:39:16 +00:00
Bruce Momjian 14531e0c44 Rename irix5 port to irix. 2004-05-19 21:37:43 +00:00
Bruce Momjian bef228d1ee Add end-of-dump markers for pg_dump and pg_dumpall. 2004-05-19 21:21:26 +00:00
Bruce Momjian 8a91100379 Only do pkglib_path if needed. 2004-05-19 21:17:33 +00:00
Bruce Momjian 4056279958 Only do find_my_exec if it doesn't come from the postmaster. 2004-05-19 19:39:27 +00:00
Bruce Momjian 9ee3310768 Add get_pkglib_path to postmaster.c 2004-05-19 19:11:25 +00:00
Bruce Momjian 5a7e1a187c Move find_my_exec lower so elog() works, per Tom. 2004-05-19 18:58:44 +00:00
Bruce Momjian ecc198bd39 Re-add elog() to exec.c, per Tom. 2004-05-19 17:15:21 +00:00
Bruce Momjian ba71d824d5 Add MinGW to cases where libdir should be used for regression tests: 
case $host_platform in
        *-*-cygwin*|*-*-mingw)
            PATH=$libdir:$PATH
            export PATH
            ;;
    esac

Bruce Momjian eb8c79a129 Win32 needs -lpgport for dll creation of ecpglib. 2004-05-19 05:14:58 +00:00
Bruce Momjian dbb9aa224e Supress verbose stderr messages while trying to find my exec path. 
Per report from Christopher.
 2004-05-19 04:36:33 +00:00
Neil Conway 132d09054e Minor correction for previous SQLSTATE patch: I changed dsqrt() to emit the 
right error code previously, and this patch applies an analogous change
to numeric_sqrt().
 2004-05-19 04:32:26 +00:00
Bruce Momjian f16874c23d Win32 can't have the same function coming from two library object files, 
so we make is_absolute_path a macro so libpq doesn't use path.o.
 2004-05-19 04:21:49 +00:00
Bruce Momjian 48eb73b556 Allow zic to compile by defining a "" value for my_exec_path. It isn't 
used by zic anyway.
 2004-05-19 01:17:42 +00:00
Tom Lane 07f2b767dc setRuleCheckAsUser has to be applied to any subqueries appearing in a 
rule's event_qual, not only to the rule's action.  Per example from
Arturs Zoldners.
 2004-05-18 22:49:51 +00:00
Bruce Momjian eb79aea9ed Move get_pkglib_path up into main.c too. 2004-05-18 20:27:25 +00:00
Bruce Momjian a9fad44372 Move find_my_exec() way up into main.c so it is available to the 
timezone code and other places.

Remove elog() calls from find_my_exec;  do fprintf(stderr) instead.  We
can then remove the exec.c handling in the makefile because it doesn't
have to be built to suppress elog calls.
 2004-05-18 20:18:59 +00:00
Bruce Momjian f3f8d36a57 Update Makefile dependencies for Win32 timezones, per Claudio. 2004-05-18 04:10:33 +00:00
Bruce Momjian 3b382d1ae3 Clean up some relative path install issues with Claudio's help. 2004-05-18 03:36:45 +00:00
Bruce Momjian 3febb477e6 Reorganize code to allow path-relative installs. 
Create new get_* functions to access compiled-in paths and adjust if
relative installs are to be used.

Clean up substitute_libpath_macro() code.
 2004-05-17 14:35:34 +00:00
Bruce Momjian 85383214ea Rename backendbin to backend_exec in initdb.c. 2004-05-17 13:17:29 +00:00
Neil Conway 2871f60f23 Change ln(), log(), power(), and sqrt() to emit the correct SQLSTATE 
error codes for certain error conditions, as specified by SQL2003.
 2004-05-16 23:18:55 +00:00
Neil Conway 52c82d590a Remove an unused (and empty) header file. 2004-05-14 22:21:43 +00:00
Neil Conway 0079547bcb Implement the width_bucket() function, per SQL2003. This commit only adds 
a variant of the function for the 'numeric' datatype; it would be possible
to add additional variants for other datatypes, but I haven't done so yet.

This commit includes regression tests and minimal documentation; if we
want developers to actually use this function in applications, we'll
probably need to document what it does more fully.
