* No more #ifdef XLOG.Vadim B. Mikheev2000-11-30

* XLOG stuff for sequences.Vadim B. Mikheev2000-11-30
| | | | CommitDelay in guc.c
* Rearrange bufmgr header files so that buf_internals.h need not beTom Lane2000-11-30
| | | | | | | included by everything that includes bufmgr.h --- it's supposed to be internals, after all, not part of the API! This fixes the conflict against FreeBSD headers reported by Rosenman, by making it unnecessary for s_lock.h to be included by plperl.c.
* Significant cleanups in SysV IPC handling (shared mem and semaphores).Tom Lane2000-11-28
| | | | | | | | | | | IPC key assignment will now work correctly even when multiple postmasters are using same logical port number (which is possible given -k switch). There is only one shared-mem segment per postmaster now, not 3. Rip out broken code for non-TAS case in bufmgr and xlog, substitute a complete S_LOCK emulation using semaphores in spin.c. TAS and non-TAS logic is now exactly the same. When deadlock is detected, "Deadlock detected" is now the elog(ERROR) message, rather than a NOTICE that comes out before an unhelpful ERROR.
* Check for link(2) failure.Tom Lane2000-11-27

* Store current LC_COLLATE and LC_CTYPE settings in pg_control during initdb;Tom Lane2000-11-25
| | | | | | | | | | re-adopt these settings at every postmaster or standalone-backend startup. This should fix problems with indexes becoming corrupt due to failure to provide consistent locale environment for postmaster at all times. Also, refuse to start up a non-locale-enabled compilation in a database originally initdb'd with a non-C locale. Suppress LIKE index optimization if locale is not "C" or "POSIX" (are there any other locales where it's safe?). Issue NOTICE during initdb if selected locale disables LIKE optimization.
* Refine log/error messages. Print out the errno message, not the number.Peter Eisentraut2000-11-21

* Change SearchSysCache coding conventions so that a reference count isTom Lane2000-11-16

* Make pgsql compile on FreeBSD-alpha.Bruce Momjian2000-11-16
| | | | | | | | | | | | | | | | | | Context diff this time. Remove -m486 compile args for FreeBSD-i386, compile -O2 on i386. Compile with only -O on alpha for codegen safety. Make the port use the TEST_AND_SET for alpha and i386 on FreeBSD. Fix a lot of bogus string formats for outputting pointers (cast to int and %u/%x replaced with no cast and %p), and 'Size'(size_t) are now cast to 'unsigned long' and output with %lu/ Remove an unused variable.

* Minor cleanup of tableOid-related coding.Tom Lane2000-11-14

* Clean up syscache so that recursive invocation is safe, and remove errorTom Lane2000-11-10
| | | | | | | | message about recursive use of a syscache. Also remove most of the specialized indexscan routines in indexing.c --- it turns out that catcache.c is perfectly able to perform the indexscan for itself, in fact has already looked up all the information needed to do so! This should be faster as well as needing far less boilerplate code.
* Auto checkpoint creation.Vadim B. Mikheev2000-11-09

* Make DROP TABLE rollback-able: postpone physical file delete until commit.Tom Lane2000-11-08
| | | | | | | | | (WAL logging for this is not done yet, however.) Clean up a number of really crufty things that are no longer needed now that DROP behaves nicely. Make temp table mapper do the right things when drop or rename affecting a temp table is rolled back. Also, remove "relation modified while in use" error check, in favor of locking tables at first reference and holding that lock throughout the statement.
* New CHECKPOINT command.Vadim B. Mikheev2000-11-05
| | | | | Auto removing of offline log files and creating new file at checkpoint time.

* Fix AbortOutOfAnyTransaction logic to avoid notice aboutTom Lane2000-10-24
| | | | | | 'AbortTransaction and not in in-progress state' when client disconnects just after an error. Notice seems pretty harmless, so I'm not going to worry about back-patching this into 7.0.* ...

* If a field is incompressible ('compressed' data is actually larger thanTom Lane2000-10-23
| | | | | | | | source, due to addition of header overhead), store it as plain data rather than pseudo-compressed data. This saves a few microseconds when reading it out, but much more importantly guarantees that the toaster won't actually expand tuples that contain incompressible data. That's essential to avoid 'Tuple too big' failures with large objects.
* New relcache hash table with RelFileNode as key to be usedVadim B. Mikheev2000-10-23
| | | | | | | from bufmgr - it would be nice to have separate hash in smgr for node <--> fd mappings, but for the moment it's easy to add new hash to relcache. Fixed small bug in xlog.c:ReadRecord.
* Makeover for Unixware 7.1.1Peter Eisentraut2000-10-22
| | | | | | | | | | | | | | | | | | | | | | | | | | * Makefile: Add more standard targets. Improve shell redirection in GNU make detection. * src/backend/access/transam/rmgr.c: Fix incorrect(?) C. * src/backend/libpq/pqcomm.c (StreamConnection): Work around accept() bug. * src/include/port/unixware.h: ...with help from here. * src/backend/nodes/print.c (plannode_type): Remove some "break"s after "return"s. * src/backend/tcop/dest.c (DestToFunction): ditto. * src/backend/nodes/readfuncs.c: Add proper prototypes. * src/backend/utils/adt/numutils.c (pg_atoi): Cope specially with strtol() setting EINVAL. This saves us from creating an extra set of regression test output for the affected systems. * src/include/storage/s_lock.h (tas): Correct prototype. * src/interfaces/libpq/fe-connect.c (parseServiceInfo): Don't use variable as dimension in array definition. * src/makefiles/Makefile.unixware: Add support for GCC. * src/template/unixware: same here * src/test/regress/expected/abstime-solaris-1947.out: Adjust whitespace. * src/test/regress/expected/horology-solaris-1947.out: Part of this file was evidently missing. * src/test/regress/pg_regress.sh: Fix shell. mkdir -p returns non-zero if the directory exists. * src/test/regress/resultmap: Add entries for Unixware.

* Ensure that catcache 'busy' flags are reset at transaction abort.Tom Lane2000-08-06
| | | | | | Without this, an elog during cache-entry load leaves that catcache unusable. elog in that segment of code is pretty unusual but it can happen.
* Fix tuptoaster bugs induced by making bytea toastable. Durn thing wasTom Lane2000-08-04
| | | | | | | | | trying to toast tuples inserted into toast tables! Fix is two-pronged: first, ensure all columns of a toast table are marked attstorage='p', and second, alter the target chunk size so that it's less than the threshold for trying to toast a tuple. (Code tried to do that but the expression was wrong.) A few cosmetic cleanups in tuptoaster too. NOTE: initdb forced due to change in toaster chunk-size.
* Modify heap_open()/heap_openr() API per pghackers discussion of 11 July.Tom Lane2000-08-03
| | | | | | | | | These two routines will now ALWAYS elog() on failure, whether you ask for a lock or not. If you really want to get a NULL return on failure, call the new routines heap_open_nofail()/heap_openr_nofail(). By my count there are only about three places that actually want that behavior. There were rather more than three places that were missing the check they needed to make under the old convention :-(.
