Tom Lane 58f337a343 Centralize implementation of delay code by creating a pg_usleep()
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?

Tom Lane 87bd956385 Restructure smgr API as per recent proposal. smgr no longer depends on
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.

Neil Conway f06e79525a Win32 signals cleanup. Patch by Magnus Hagander, with input from Claudio
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

Neil Conway e66fcce672 Use memmove() rather than memcpy() in set_var_from_var(). If this function
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.

Tom Lane 391c3811a2 Rename SortMem and VacuumMem to work_mem and maintenance_work_mem.
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.

Joe Conway 12661642c8 Add function (actually an int4 and an int8 version) that generates
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.

and finally some editorializing from Neil Conway.

Bruce Momjian e5e5a323ca Briefly,
* 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...

Tom Lane 18f9d7c74e Make USING and WITH optional to bring the syntax of \copy into exact
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.

Tom Lane 2f0d43b251 Review uses of IsUnderPostmaster, change some tests to look at
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.

Tom Lane 31a0f1d33b Fix oversight in check_ungrouped_columns optimization that avoids
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.
2004-01-28 07:46:44 +00:00
Tom Lane 4405b3e05e simplify_function() mustn't try to evaluate functions that return
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.

Bruce Momjian 70d5811514 Pgindent win32 signal code. 2004-01-27 00:46:58 +00:00
Bruce Momjian 50491963cb Here's the latest win32 signals code, this time in the form of a patch
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.

Bruce Momjian eec08b95e7 [all] Removed call to getppid in SendPostmasterSignal, replacing with a
PostmasterPid variable, which gets set (early) in PostmasterMain
getppid would not be the postmaster?

[fork/exec] Implements processCancelRequest by keeping an array of

pid/cancel_key structs in shared mem

[fork/exec] Moves AttachSharedMemoryAndSemaphores call for backends into
SubPostmasterMain

[win32] Implements reaper/waitpid by keeping an arrays of children
pids,handles in postmaster local mem
      - this item is largely untested, for reasons which should be
obvious, but appears sound

[win32/all] Added extern for pgpipe in Win32 case, and changed the second
pipe call (which seems to have been missed earlier) to pgpipe

[win32] #define'd ftruncate to chsize in the Win32 case

[win32] PG_USLEEP for Win32 has a misplaced paren. Fixed.

[win32] DLLIMPORT handling for MingW case
