c53611e3e7 This patch brings up to date what I did last year (now unfortunately
bitrotted) to allow the logging of the end of a session, enabled by
the config setting "log_disconnections".

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

9e218af7ed Fix a read of uninitialized memory in next_token() of hba.c, spotted via
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.

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.

92aa462247 Second try at IPv4-to-v6 mapping code; avoid assuming that the struct

df63503dc2 Have a go at fixing various outstanding portability issues in code that
was modified for IPv6.  Use a robust definition of struct sockaddr_storage,
do a proper configure test to see if ss_len exists, don't assume that
getnameinfo() will handle AF_UNIX sockets, don't trust getaddrinfo to
return the protocol we ask for, etc.  This incorporates several outstanding
patches from Kurt Roeckx, but I'm to blame for anything that doesn't
work ...

274328c8a8 Avoid use of int64_t, which seems not to be very portable. Simplify
padding logic for struct sockaddr_storage --- original version did not
do what it claimed to when SALEN is defined.

e5549a272d Back out this patch because it is patched inside a later patch.
---------------------------------------------------------------------------

here is a patch that allows CIDR netmasks in pg_hba.conf. It allows two
address/mask forms:

. address/maskbits, or
. address netmask (as now)

If the patch is accepted I will submit a documentation patch to cover
it.

This is submitted by agreement with Kurt Roeckx, who has worked on a
patch that covers this and other IPv6 issues.

6bdb7aa4db libpq can now talk to either 3.0 or 2.0 protocol servers. It first tries
protocol 3, then falls back to 2 if postmaster rejects the startup packet
with an old-format error message.  A side benefit of the rewrite is that
SSL-encrypted connections can now be made without blocking.  (I think,
anyway, but do not have a good way to test.)

b1ee615a7f COPY BINARY uses the new binary I/O routines. Update a few more datatypes

075a0078df I think we're done with protocol instability, so mark server and libpq
as speaking the one true 3.0 protocol.

c0a8c3ac13 Update 3.0 protocol support to match recent agreements about how to
handle multiple 'formats' for data I/O.  Restructure CommandDest and
DestReceiver stuff one more time (it's finally starting to look a bit
clean though).  Code now matches latest 3.0 protocol document as far
as message formats go --- but there is no support for binary I/O yet.

755d191700 Add display of eventual result RowDescription (if any) to the output
of Describe on a prepared statement.  This was in the original 3.0
protocol proposal, but I took it out for reasons that seemed good at
the time.  Put it back per yesterday's pghackers discussion.

16503e6fa4 Extended query protocol: parse, bind, execute, describe FE/BE messages.
Only lightly tested as yet, since libpq doesn't know anything about 'em.
2003-05-05 00:44:56 +00:00
Tom Lane
4db9689d1a Add transaction status field to ReadyForQuery messages, and make room
for tableID/columnID in RowDescription.  (The latter isn't really
implemented yet though --- the backend always sends zeroes, and libpq
just throws away the data.)

9cbaf72177 In the continuing saga of FE/BE protocol revisions, add reporting of
initial values and runtime changes in selected parameters.  This gets
rid of the need for an initial 'select pg_client_encoding()' query in
libpq, bringing us back to one message transmitted in each direction
for a standard connection startup.  To allow server version to be sent
using the same GUC mechanism that handles other parameters, invent the
concept of a never-settable GUC parameter: you can 'show server_version'
but it's not settable by any GUC input source.  Create 'lc_collate' and
'lc_ctype' never-settable parameters so that people can find out these
settings without need for pg_controldata.  (These side ideas were all
discussed some time ago in pgsql-hackers, but not yet implemented.)

f690920a75 Infrastructure for upgraded error reporting mechanism. elog.c is
rewritten and the protocol is changed, but most elog calls are still
elog calls.  Also, we need to contemplate mechanisms for controlling
all this functionality --- eg, how much stuff should appear in the
postmaster log?  And what API should libpq expose for it?
2003-04-24 21:16:45 +00:00

5ed27e35f3 Another round of protocol changes. Backend-to-frontend messages now all
have length words.  COPY OUT reimplemented per new protocol: it doesn't
need \. anymore, thank goodness.  COPY BINARY to/from frontend works,
at least as far as the backend is concerned --- libpq's PQgetline API
is not up to snuff, and will have to be replaced with something that is
null-safe.  libpq uses message length words for performance improvement
(no cycles wasted rescanning long messages), but not yet for error
recovery.
2003-04-22 00:08:07 +00:00
Tom Lane
bd8d441775 Second round of FE/BE protocol changes. Frontend->backend messages now
have length counts, and COPY IN data is packetized into messages.

cb7fb3ca95 First phase of FE/BE protocol modifications: new StartupPacket layout
with variable-width fields.  No more truncation of long user names.
Also, libpq can now send its environment-variable-driven SET commands
as part of the startup packet, saving round trips to server.

15ab7a8720 Where available, use utime() or utimes() to update the file mod time
of the socket file and socket lock file; this should prevent both of them
from being removed by even the stupidest varieties of /tmp-cleaning
script.  Per suggestion from Giles Lean.

8fc86dd593 We have just finished porting the old KAME IPv6 patch over to

support to postgres. I've tested it out on 7.2.3 and has
been running perfectly stable.
