* Replace time_t with pg_time_t (same values, but always int64) in on-diskTom Lane2008-02-17
| | | | | | | | | | | | | | data structures and backend internal APIs. This solves problems we've seen recently with inconsistent layout of pg_control between machines that have 32-bit time_t and those that have already migrated to 64-bit time_t. Also, we can get out from under the problem that Windows' Unix-API emulation is not consistent about the width of time_t. There are a few remaining places where local time_t variables are used to hold the current or recent result of time(NULL). I didn't bother changing these since they do not affect any cross-module APIs and surely all platforms will have 64-bit time_t before overflow becomes an actual risk. time_t should be avoided for anything visible to extension modules, however.
* Fix two different copy-and-paste-os in CSV log rotation logic; one that led toTom Lane2008-01-25
| | | | | | a double-pfree crash and another that effectively disabled size-based rotation for CSV logs. Also suppress a memory leak and make some trivial cosmetic improvements. Per bug #3901 from Chris Hoover and additional code-reading.

* Fix erroneous Assert() in syslogger process start in EXEC_BACKEND case,Tom Lane2007-09-22
| | | | | per ITAGAKI Takahiro. Also, rewrite syslogger_forkexec() in hopes of eliminating the confusion in the first place.

* Provide for logfiles in machine readable CSV format. In consequence, renameAndrew Dunstan2007-08-19
| | | | | | redirect_stderr to logging_collector. Original patch from Arul Shaji, subsequently modified by Greg Smith, and then heavily modified by me.
* Switch over to using the src/timezone functions for formatting timestampsTom Lane2007-08-04
| | | | | | | | | | | | | | displayed in the postmaster log. This avoids Windows-specific problems with localized time zone names that are in the wrong encoding, and generally seems like a good idea to forestall other potential platform-dependent issues. To preserve the existing behavior that all backends will log in the same time zone, create a new GUC variable log_timezone that can only be changed on a system-wide basis, and reference log-related calculations to that zone instead of the TimeZone variable. This fixes the issue reported by Hiroshi Saito that timestamps printed by xlog.c startup could be improperly localized on Windows. We still need a simpler patch for that problem in the back branches, however.
* Move session_start out of MyProcPort stucture and make it a global called ↵Andrew Dunstan2007-08-02
| | | | | | | | MyStartTime, so that we will be able to create a cookie for all processes for CSVlogs. It is set wherever MyProcPid is set. Take the opportunity to remove the now unnecessary session-only restriction on the %s and %c escapes in log_line_prefix.
* Make sure syslogPipe runs in binary mode on Windows to avoid corrupting the ↵Andrew Dunstan2007-08-02
| | | | pipe chunking protocol. Backport to 8.0
* Only use the pipe chunking protocol if we know the syslogger shouldAndrew Dunstan2007-07-19
| | | | | | | be catching stderr output, and we are not ourselves the syslogger. Otherwise, go directly to stderr. Bug noticed by Tom Lane. Backpatch as far as 8.0.
* Implement a chunking protocol for writes to the syslogger pipe, with messagesAndrew Dunstan2007-06-14
| | | | | | | | | reassembled in the syslogger before writing to the log file. This prevents partial messages from being written, which mucks up log rotation, and messages from different backends being interleaved, which causes garbled logs. Backport as far as 8.0, where the syslogger was introduced. Tom Lane and Andrew Dunstan
* Remove ill-conceived CRLF translation for Windows in syslogger.Andrew Dunstan2007-06-04

* Update CVS HEAD for 2007 copyright. Back branches are typically notBruce Momjian2007-01-05
| | | | back-stamped for this.
* On systems that have setsid(2) (which should be just about everything exceptTom Lane2006-11-21
| | | | | | | | | | | | | Windows), arrange for each postmaster child process to be its own process group leader, and deliver signals SIGINT, SIGTERM, SIGQUIT to the whole process group not only the direct child process. This provides saner behavior for archive and recovery scripts; in particular, it's possible to shut down a warm-standby recovery server using "pg_ctl stop -m immediate", since delivery of SIGQUIT to the startup subprocess will result in killing the waiting recovery_command. Also, this makes Query Cancel and statement_timeout apply to scripts being run from backends via system(). (There is no support in the core backend for that, but it's widely done using untrusted PLs.) Per gripe from Stephen Harris and subsequent discussion.
* In a Windows backend, don't build src/port/pgsleep.c's version ofTom Lane2006-07-16
| | | | | | | | pg_usleep at all. Instead call the replacement function in port/win32/signal.c by that name. Avoids tricky macro-redefinition logic and suppresses a compiler warning; furthermore it ensures that no one can accidentally use the non-signal-aware version of pg_usleep in a Windows backend.
* Alphabetically order reference to include files, "S"-"Z".Bruce Momjian2006-07-11

* Add GUC update_process_title to control whether 'ps' display is updatedBruce Momjian2006-06-27
| | | | for every command, default to on.
* Merge postmaster and postgres command into just postgres. postmasterPeter Eisentraut2006-06-18
| | | | | symlink is kept for now for compatibility. To call single-user mode, use postgres --single.
* Prepare code to be built by MSVC:Bruce Momjian2006-06-07
| | | | | | | | | | o remove many WIN32_CLIENT_ONLY defines o add WIN32_ONLY_COMPILER define o add 3rd argument to open() for portability o add include/port/win32_msvc directory for system includes Magnus Hagander

* Rearrange backend startup sequence so that ShmemIndexLock can becomeTom Lane2006-01-04
| | | | | | an LWLock instead of a spinlock. This hardly matters on Unix machines but should improve startup performance on Windows (or any port using EXEC_BACKEND). Per previous discussion.
* Re-run pgindent, fixing a problem where comment lines after a blankBruce Momjian2005-11-22
| | | | | | | | | comment line where output as too long, and update typedefs for /lib directory. Also fix case where identifiers were used as variable names in the backend, but as typedefs in ecpg (favor the backend for indenting). Backpatch to 8.1.X.

* Update DAYS_PER_MONTH comment.Bruce Momjian2005-07-21
| | | | Add SECS_PER_YEAR and MINS_PER_HOUR macros.
* Add time/date macros for code clarity:Bruce Momjian2005-07-21
| | | | | | | #define DAYS_PER_YEAR 365.25 #define MONTHS_PER_YEAR 12 #define DAYS_PER_MONTH 30 #define HOURS_PER_DAY 24
* Arrange for the postmaster (and standalone backends, initdb, etc) toTom Lane2005-07-04
| | | | | | | | chdir into PGDATA and subsequently use relative paths instead of absolute paths to access all files under PGDATA. This seems to give a small performance improvement, and it should make the system more robust against naive DBAs doing things like moving a database directory that has a live postmaster in it. Per recent discussion.
* Attached patch gets rid of the global timezone in the following steps:Bruce Momjian2005-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * Changes the APIs to the timezone functions to take a pg_tz pointer as an argument, representing the timezone to use for the selected operation. * Adds a global_timezone variable that represents the current timezone in the backend as set by SET TIMEZONE (or guc, or env, etc). * Implements a hash-table cache of loaded tables, so we don't have to read and parse the TZ file everytime we change a timezone. While not necesasry now (we don't change timezones very often), I beleive this will be necessary (or at least good) when "multiple timezones in the same query" is eventually implemented. And code-wise, this was the time to do it. There are no user-visible changes at this time. Implementing the "multiple zones in one query" is a later step... This also gets rid of some of the cruft needed to "back out a timezone change", since we previously couldn't check a timezone unless it was activated first. Passes regression tests on win32, linux (slackware 10) and solaris x86. Magnus Hagander
* Fix problem with infinite recursion between write_syslogger_file andTom Lane2005-03-12
| | | | | | | | elog if the former has trouble writing its file. Code review for Magnus' patch to redirect stderr to syslog on Windows (Bruce's version seems right, but did some minor prettification). Backpatch both changes to 8.0 branch.
* Refactor fork()-related code. We need to do various housekeeping tasksNeil Conway2005-03-10
| | | | | | | | | | before we can invoke fork() -- flush stdio buffers, save and restore the profiling timer on Linux with LINUX_PROFILE, and handle BeOS stuff. This patch moves that code into a single function, fork_process(), instead of duplicating it at the various callsites of fork(). This patch doesn't address the EXEC_BACKEND case; there is room for further cleanup there.
* Some more missed copyright notices. Many of these look like theyTom Lane2005-01-01

* Rotate on time boundaries that are sensible per local time rather than GMT.Tom Lane2004-09-21
| | | | | Also, avoid truncating the file we just wrote into, which might otherwise easily happen at DST boundaries. Ed L. and Tom Lane.
* Replace log_filename_prefix with more general log_filename parameter,Tom Lane2004-08-31
| | | | | | | to allow DBA to choose the form in which log filenames reflect the current time. Also allow for truncating instead of appending to pre-existing files --- this is convenient when the log filename pattern rewrites the same names cyclically. Per Ed L.

recommend that people go get Apache's rotatelogs program. Additional benefits are that configuration is done through GUC, rather than externally, and that the postmaster can monitor the log rotator and restart it after failure (though we certainly hope that won't happen often). Andreas Pflug, some rework by Tom Lane.
