* Change made to elog:Bruce Momjian2002-03-06
| | | | | | | | | | | | | | | | | | | o Change all current CVS messages of NOTICE to WARNING. We were going to do this just before 7.3 beta but it has to be done now, as you will see below. o Change current INFO messages that should be controlled by client_min_messages to NOTICE. o Force remaining INFO messages, like from EXPLAIN, VACUUM VERBOSE, etc. to always go to the client. o Remove INFO from the client_min_messages options and add NOTICE. Seems we do need three non-ERROR elog levels to handle the various behaviors we need for these messages. Regression passed.
* Further work on elog cleanup: fix some bogosities in elog's logic aboutTom Lane2002-03-04
| | | | | | | when to send what to which, prevent recursion by introducing new COMMERROR elog level for client-communication problems, get rid of direct writes to stderr in backend/libpq files, prevent non-error elogs from going to client during the authentication cycle.
* Commit to match discussed elog() changes. Only update is that LOG isBruce Momjian2002-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | now just below FATAL in server_min_messages. Added more text to highlight ordering difference between it and client_min_messages. --------------------------------------------------------------------------- REALLYFATAL => PANIC STOP => PANIC New INFO level the prints to client by default New LOG level the prints to server log by default Cause VACUUM information to print only to the client NOTICE => INFO where purely information messages are sent DEBUG => LOG for purely server status messages DEBUG removed, kept as backward compatible DEBUG5, DEBUG4, DEBUG3, DEBUG2, DEBUG1 added DebugLvl removed in favor of new DEBUG[1-5] symbols New server_min_messages GUC parameter with values: DEBUG[5-1], INFO, NOTICE, ERROR, LOG, FATAL, PANIC New client_min_messages GUC parameter with values: DEBUG[5-1], LOG, INFO, NOTICE, ERROR, FATAL, PANIC Server startup now logged with LOG instead of DEBUG Remove debug_level GUC parameter elog() numbers now start at 10 Add test to print error message if older elog() values are passed to elog() Bootstrap mode now has a -d that requires an argument, like postmaster
* User and database-specific session defaults for run-time configurationPeter Eisentraut2002-03-01
| | | | variables. New commands ALTER DATABASE ... SET and ALTER USER ... SET.
* Tweak pg_exec_query_string so that we close down transaction commandTom Lane2002-02-27
| | | | | | | | | before reporting command-complete message for the final command of a query string. This way, any errors detected during finish_xact_command (such as RI violations) will appear to be part of the final command, rather than coming out after the command is reported complete. This avoids confusing PQendcopy and other not-overly-bright clients. Per Lee Harr's bug report of 25-Feb-02.
* Clean up BeginCommand and related routines. BeginCommand and EndCommandTom Lane2002-02-27
| | | | | | | | | | | are now both invoked once per received SQL command (raw parsetree) from pg_exec_query_string. BeginCommand is actually just an empty routine at the moment --- all its former operations have been pushed into tuple receiver setup routines in printtup.c. This makes for a clean distinction between BeginCommand/EndCommand (once per command) and the tuple receiver setup/teardown routines (once per ExecutorRun call), whereas the old code was quite ad hoc. Along the way, clean up the calling conventions for ExecutorRun a little bit.
* Restructure command-completion-report code so that there is just oneTom Lane2002-02-26
| | | | | | | report for each received SQL command, regardless of rewriting activity. Also ensure that this report comes from the 'original' command, not the last command generated by rewrite; this fixes 7.2 breakage for INSERT commands that have actions added by rules. Fernando Nasser and Tom Lane.
* Save source of GUC settings, allowing different sources to be processed inPeter Eisentraut2002-02-23
| | | | any order without affecting results.
* Remove some unnecessary pqsignal() calls to shave a few cycles offTom Lane2002-02-19
| | | | backend startup.
* The result of getopt() should be compared to -1, not EOF, perTom Lane2002-01-10
| | | | pgsql-hackers discussion of this date.
* Do not accept interrupts in RESUME_INTERRUPTS() and END_CRIT_SECTION()Tom Lane2002-01-01
| | | | | | macros, but only at explicit CHECK_FOR_INTERRUPTS() calls. Not clear whether overenthusiastic acceptance of interrupts accounts for any real bugs, but it definitely seems risky and unnecessary.
* Replace pq_getbytes(&ch, 1) calls with pq_getbyte(), which is easierTom Lane2001-12-04
| | | | | | | to use and significantly faster. This tweak saves 25% (!) of the runtime of COPY IN in a test with 8000-character lines. I wouldn't normally commit a performance improvement this late in the cycle, but 25% got my attention...
* Clean up usage-statistics display code (ShowUsage and friends). StatFpTom Lane2001-11-10
| | | | is gone, usage messages now go through elog(DEBUG).
* New pgindent run with fixes suggested by Tom. Patch manually reviewed,Bruce Momjian2001-11-05
| | | | initdb/regression tests pass.
* Another pgindent run. Fixes enum indenting, and improves #endifBruce Momjian2001-10-28
| | | | spacing. Also adds space for one-line comments.
* pgindent run on all C files. Java run to follow. initdb/regressionBruce Momjian2001-10-25
| | | | tests pass.
* Fix getopt-vs-init_ps_display problem by copying original argv[] info,Tom Lane2001-10-21
| | | | | | per suggestion from Peter. Simplify several APIs by transmitting the original argv location directly from main.c to ps_status.c, instead of passing it down through several levels of subroutines.
* Set optreset on platforms that have it before launching postmasterTom Lane2001-10-19
| | | | | | subprocesses; perhaps this will fix portability problem just noted by Lockhart. Also, move test for bad permissions of DataDir to a more logical place.
* Ensure that all startup paths (postmaster, standalone postgres, orTom Lane2001-10-19
| | | | | | | bootstrap) check for a valid PG_VERSION file before looking at anything else in the data directory. This fixes confusing error report when trying to start current sources in a pre-7.1 data directory. Per trouble report from Rich Shepard 10/18/01.
* Move init_ps_display from postgres.c to postmaster.c, putting itTom Lane2001-10-19
| | | | | | | | | | | just after receipt of the startup packet. Now, postmaster children that are waiting for client authentication response will show as 'postgres: user database host authentication'. Also, do an init_ps_display for startup/shutdown/checkpoint subprocesses, so that they are readily identifiable as well. Fix an obscure race condition that could lead to Assert failure in the postmaster --- attempting to start a checkpoint process before any connections have been received led to calling PostmasterRandom before setting random_seed.
* Remove useless LockDisable() function and associated overhead, per myTom Lane2001-09-27
| | | | proposal of 26-Aug.
* Add an overall timeout on the client authentication cycle, so thatTom Lane2001-09-21
| | | | | | | a hung client or lost connection can't indefinitely block a postmaster child (not to mention the possibility of deliberate DoS attacks). Timeout is controlled by new authentication_timeout GUC variable, which I set to 60 seconds by default ... does that seem reasonable?
* Clean up some confusion about where and how to set whereToSendOutput.Tom Lane2001-09-08
| | | | | | | | We will no longer try to send elog messages to the client before we have initialized backend libpq (oops); however, reporting bogus commandline switches via elog does work now (not irrelevant, because of PGOPTIONS). Fix problem with inappropriate sending of checkpoint-process messages to stderr.
* Enable SIGTERM and SIGQUIT during client authentication soJan Wieck2001-09-07
| | | | | | | the postmaster can kill the forked off processes when shutdown is requested. Jan
* 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.
* 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).
* Load pg_hba.conf and pg_ident.conf on startup and SIGHUP into List ofBruce Momjian2001-07-30
| | | | | | Lists, and use that for user validation. Bruce Momjian

* Fix a couple remaining places where GUC variables were assigned toTom Lane2001-06-25

* Statistical system views (yet without the config stuff, butJan Wieck2001-06-22
| | | | | | | it's hard to keep such massive changes in sync with the tree so I need to get it in and work from there now). Jan
* Handle reading of startup packet and authentication exchange after forkingPeter Eisentraut2001-06-20
| | | | | | | | | | a new postmaster child process. This should eliminate problems with authentication blocking (e.g., ident, SSL init) and also reduce problems with the accept queue filling up under heavy load. The option to send elog output to a different file per backend (postgres -o) has been disabled for now because the initialization would have to happen in a different order and it's not clear we want to keep this anyway.

* RESET ALL secondary patch:Bruce Momjian2001-06-18
| | | | | | | | | | Here is Tomified version of my 2 pending patches. Dropped the set_.._real change as it is not needed. Desc would be: * use GUC for settings from cmdline Marko Kreen
* Extend GUC concepts of parse_hook and assign_hook to all four supportedTom Lane2001-06-12
| | | | | | | | | | | | datatypes, not only strings. parse_hook is useless for bool, I suppose, but it seems possibly useful for int and double to apply variable-specific constraints that are more complex than simple range limits. assign_hook is definitely useful for all datatypes --- we need it right now for bool to support date cache reset when changing Australian timezone rule setting. Also, clean up some residual problems with the reset all/show all patch, including memory leaks and mistaken reset of PostPortNumber. It seems best that RESET ALL not touch variables that don't have SUSET or USERSET context.

* XLOG (and related) changes:Tom Lane2001-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Store two past checkpoint locations, not just one, in pg_control. On startup, we fall back to the older checkpoint if the newer one is unreadable. Also, a physical copy of the newest checkpoint record is kept in pg_control for possible use in disaster recovery (ie, complete loss of pg_xlog). Also add a version number for pg_control itself. Remove archdir from pg_control; it ought to be a GUC parameter, not a special case (not that it's implemented yet anyway). * Suppress successive checkpoint records when nothing has been entered in the WAL log since the last one. This is not so much to avoid I/O as to make it actually useful to keep track of the last two checkpoints. If the things are right next to each other then there's not a lot of redundancy gained... * Change CRC scheme to a true 64-bit CRC, not a pair of 32-bit CRCs on alternate bytes. Polynomial borrowed from ECMA DLT1 standard. * Fix XLOG record length handling so that it will work at BLCKSZ = 32k. * Change XID allocation to work more like OID allocation. (This is of dubious necessity, but I think it's a good idea anyway.) * Fix a number of minor bugs, such as off-by-one logic for XLOG file wraparound at the 4 gig mark. * Add documentation and clean up some coding infelicities; move file format declarations out to include files where planned contrib utilities can get at them. * Checkpoint will now occur every CHECKPOINT_SEGMENTS log segments or every CHECKPOINT_TIMEOUT seconds, whichever comes first. It is also possible to force a checkpoint by sending SIGUSR1 to the postmaster (undocumented feature...) * Defend against kill -9 postmaster by storing shmem block's key and ID in postmaster.pid lockfile, and checking at startup to ensure that no processes are still connected to old shmem block (if it still exists). * Switch backends to accept SIGQUIT rather than SIGUSR1 for emergency stop, for symmetry with postmaster and xlog utilities. Clean up signal handling in bootstrap.c so that xlog utilities launched by postmaster will react to signals better. * Standalone bootstrap now grabs lockfile in target directory, as added insurance against running it in parallel with live postmaster.
* hold interupts during LockWaitCancel().Hiroshi Inoue2001-03-09

* When under postmaster, bogus arguments should cause proc_exit(0) notTom Lane2001-02-24
| | | | | proc_exit(1). Unless you think a system-wide restart is an appropriate response to bogus PGOPTIONS, that is.
* Remove bogus set_ps_display call --- changing displayed status here isTom Lane2001-02-18
| | | | | | either wrong or unnecessary in most cases, and on systems where setting status takes a kernel call, the overhead of setting status three times per command rather than two is annoying.
