* Check only live tuples for OID validity, to avoid issues after ALTERTom Lane2004-02-12
| | | | TABLE. Per recent discussion.
* Added hints about the reason, why the command string inJan Wieck2004-02-12

* Commit the reasonably uncontroversial parts of J.R. Nield's PITR patch, toTom Lane2004-02-11
| | | | | | | | | | | wit: Add a header record to each WAL segment file so that it can be reliably identified. Avoid splitting WAL records across segment files (this is not strictly necessary, but makes it simpler to incorporate the header records). Make WAL entries for file creation, deletion, and truncation (as foreseen but never implemented by Vadim). Also, add support for making XLOG_SEG_SIZE configurable at compile time, similarly to BLCKSZ. Fix a couple bugs I introduced in WAL replay during recent smgr API changes. initdb is forced due to changes in pg_control contents.
* Repair some problems in bgwriter start/stop logic. In particular, don'tTom Lane2004-02-11
| | | | | | | allow the bgwriter to start before the startup subprocess has finished ... it tends to crash otherwise. (The same problem may have existed for the checkpointer, I'm not entirely sure.) Remove some code that was redundant because the bgwriter is handled as a member of the backend list.
* Check and set thread-safe functions separately, rather than as a singleBruce Momjian2004-02-11
| | | | | | | | | | variable. Remove thread locking for non-thread-safe functions, instead throw a compile error. Platforms will have to re-run tools/thread to record their thread safety.
* Properly set NEED_REENTRANT_FUNCS for threaded libpq/ecpg.Bruce Momjian2004-02-11
| | | | Without this patch, no thread locking or *_r functions were being used.
* No need to link libpq into these programs ...Tom Lane2004-02-10

* Add configure support for determining UINT64_FORMAT, the appropriateTom Lane2004-02-10

* Looks like we need <unistd.h> for select() on Darwin.Tom Lane2004-02-10
|
* Centralize implementation of delay code by creating a pg_usleep()Tom Lane2004-02-10
| | | | | | | | | subroutine in src/port/pgsleep.c. Remove platform dependencies from miscadmin.h and put them in port.h where they belong. Extend recent vacuum cost-based-delay patch to apply to VACUUM FULL, ANALYZE, and non-btree index vacuuming. By the way, where is the documentation for the cost-based-delay patch?
* Restructure smgr API as per recent proposal. smgr no longer depends onTom Lane2004-02-10
| | | | | | | | | the relcache, and so the notion of 'blind write' is gone. This should improve efficiency in bgwriter and background checkpoint processes. Internal restructuring in md.c to remove the not-very-useful array of MdfdVec objects --- might as well just use pointers. Also remove the long-dead 'persistent main memory' storage manager (mm.c), since it seems quite unlikely to ever get resurrected.
* Win32 signals cleanup. Patch by Magnus Hagander, with input from ClaudioNeil Conway2004-02-08
| | | | | | | | | | | | | | | | | | | | | | Natoli and Bruce Momjian (and some cosmetic fixes from Neil Conway). Changes: - remove duplicate signal definitions from pqsignal.h - replace pqkill() with kill() and redefine kill() in Win32 - use ereport() in place of fprintf() in some error handling in pqsignal.c - export pg_queue_signal() and make use of it where necessary - add a console control handler for Ctrl-C and similar handling on Win32 - do WaitForSingleObjectEx() in CHECK_FOR_INTERRUPTS() on Win32; query cancelling should now work on Win32 - various other fixes and cleanups

* Use memmove() rather than memcpy() in set_var_from_var(). If this functionNeil Conway2004-02-04
| | | | | | | is asked to assign a variable to itself, it will result in doing a memcpy() on an entirely-overlapping memory range, which results in undefined behavior according to ANSI C. That said, it is unlikely to actually do anything bad on any sane libc, but this keeps valgrind quiet.
* pwdTom Lane2004-02-03

* Rename SortMem and VacuumMem to work_mem and maintenance_work_mem.Tom Lane2004-02-03
| | | | | | | Make btree index creation and initial validation of foreign-key constraints use maintenance_work_mem rather than work_mem as their memory limit. Add some code to guc.c to allow these variables to be referenced by their old names in SHOW and SET commands, for backwards compatibility.
* Add function (actually an int4 and an int8 version) that generatesJoe Conway2004-02-03
| | | | | | | | a series of numbers, optionally using an explicit step size other than the default value (one). Use function in the information_schema to replace hard-wired knowledge of INDEX_MAX_KEYS. initdb forced due to pg_proc change. Documentation update still needed -- will be committed separately.

* Fix a read of uninitialized memory in next_token() of hba.c, spotted viaNeil Conway2004-02-02
| | | | | | valgrind: a buffer passed to strncmp() had to be NUL-terminated. Original report and patch from Dennis Bjorkland, some cleanup by Andrew Dunstan, and finally some editorializing from Neil Conway.
* Adjustments for Win32-specific rename code, and add include file.Bruce Momjian2004-02-02

* Avoid generating invalid character encoding sequences in make_greater_string.Tom Lane2004-02-02
| | | | Not sure how this mistake evaded detection for so long.
* Use Tcl_PutEnv() in place of putenv() in libpgtcl, as the latter canNeil Conway2004-02-02
| | | | | apparently corrupt the Tcl runtime. Per suggestion from Michael Brusser <michael@synchronicity.com>
* Adjust rename on Win32 to only link to temp name while holding lock,Bruce Momjian2004-02-02

* Briefly,Bruce Momjian2004-02-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * configure + Makefile changes * shared memory attaching in EXEC_BACKEND case (+ minor fix for apparent cygwin bug under cygwin/EXEC_BACKEND case only) * PATH env var separator differences * missing win32 rand functions added * placeholder replacements for sync etc under port.h To those who are really interested, and there are a few of you: the attached patch + file will allow the source base to be compiled (and, for some definition, "run") under MingW, with the following caveats (I wanted to first properly fix all but the last of these, but y'all won't quit asking for a patch :-): * child death: SIGCHLD not yet sent, so as a minimum, you'll need to put in some sort of delay after StartupDatabase, and handle setting StartupPID to 0 etc (ie. the stuff the reaper() signal function is supposed to do) * dirmod.c: comment out the elog calls * dfmgr.c: some hackage required to substitute_libpath_macro * slru/xact.c: comment out the errno checking after the readdir (fixed by next version of MingW) Again, this is only if you *really* want to see postgres compile and start, and is a nice leg-up for working on the other Win32 TODO list items. Just don't expect too much else from it at this point... Claudio Natoli
* Set locale to C before doing sort in make_ctags.Bruce Momjian2004-02-01
|
* Make length() disregard trailing spaces in char(n) values, per discussionTom Lane2004-02-01
| | | | | some time ago and recent patch from Gavin Sherry. Update documentation to point out that trailing spaces are insignificant in char(n).
* Fix a probably-harmless read of uninitialized memory in mkdir_p(), toNeil Conway2004-01-31
| | | | silence a valgrind warning.
* Remove a superfluous semi-colon.Neil Conway2004-01-31

* Micro-opt: replace calls likeNeil Conway2004-01-31
| | | | | | | appendStringInfo(buf, "%s", str); with appendStringInfoString(buf, str); as the latter form is slightly faster.
* Fix text_position to not scan past end of source string in multibyteTom Lane2004-01-31
| | | | | case, per report from Korea PostgreSQL Users' Group. Also do some cosmetic cleanup in nearby code.
* Fix debug elog message to agree with name of its routine.Tom Lane2004-01-30
|
* Remove sleep() and use single PG_SLEEP call for Win32 signal handlingBruce Momjian2004-01-30
| | | | | | and consistency. Change PG_USLEEP to use SleepEx() for signal interuptability.
* Fix (debatable) spelling mistake in a comment: 'concatenate' is the usualNeil Conway2004-01-29
| | | | term, not 'catenate'.
* Make USING and WITH optional to bring the syntax of \copy into exactTom Lane2004-01-28
| | | | | | | | agreement with what the backend grammar actually accepts (which is a bit looser than what its documentation claims). Per report from Bill Moran, though I did not use his patch since it removed all the undocumented flexibility that the code historically had and the backend still has.
* Review uses of IsUnderPostmaster, change some tests to look atTom Lane2004-01-28
| | | | | | | whereToSendOutput instead because they are really inquiring about the correct client communication protocol. Update some comments. This is pointing towards supporting regular FE/BE client protocol in a standalone backend, per discussion a month or so back.

* Removed some debugging output.Michael Meskes2004-01-28

* - Issue a warning if a cursor is declared but not opened.Michael Meskes2004-01-28
| | | | | | - Fixed prototype for ECPGprepared_statement to not moan about "const char" - Fixed parsing of nested structures. - Added option to parse header files.
* Fix oversight in check_ungrouped_columns optimization that avoidsTom Lane2004-01-28
| | | | | | | unnecessary checks for complex grouping expressions: we cannot check whether the expressions are simple Vars until after we apply flatten_join_alias_vars, because in the case of FULL JOIN that routine can introduce non-Var expressions. Per example from Joel Knight.
* simplify_function() mustn't try to evaluate functions that returnTom Lane2004-01-28
| | | | | | | composite types, because TupleTableSlots aren't Datums and can't be stored in Const nodes. We can remove this restriction if we ever adopt a cleaner runtime representation for whole-tuple results, but at the moment it's broken. Per example from Thomas Hallgren.
* Run stats test separately, not as part of a parallel group, to avoidTom Lane2004-01-27
| | | | | possible failures due to stats collector not updating fast enough under heavy load. Per report from Jeremy Yoder.
* Pgindent win32 signal code.Bruce Momjian2004-01-27
|
* Here's the latest win32 signals code, this time in the form of a patchBruce Momjian2004-01-27
| | | | | | | | | | | | | | | | | against the latest shapshot. It also includes the replacement of kill() with pqkill() and sigsetmask() with pqsigsetmask(). Passes all tests fine on my linux machine once applied. Still doesn't link completely on Win32 - there are a few things still required. But much closer than before. At Bruce's request, I'm goint to write up a README file about the method of signals delivery chosen and why the others were rejected (basically a summary of the mailinglist discussions). I'll finish that up once/if the patch is accepted. Magnus Hagander
