| | | | | | | | | | | | | | | | | structs from libpq-fe.h, as we previously discussed. There turned out to be sloppy coding practices in more places than I had realized :-(, but all in all I think it was a well-worth-while exercise. I ended up adding several routines to libpq's API in order to respond to application requirements that were exposed by this work. I owe the docs crew updates for libpq.sgml to describe these changes. I'm way too tired to work on the docs tonight, however. This is the last major change I intend to submit for 6.4. I do want to see if I can make libpgtcl work with Tcl 8.0 before we go final, but hopefully that will be a minor bug fix.

* The attached patch implements some changes that were discussed aBruce Momjian1998-08-09
| | | | | | | | | | | | | | | | | | | | | | | | | couple weeks ago on the hackers and interfaces lists: 1. When the backend sends a NOTICE message and closes the connection (typically, because it was told to by the postmaster after another backend coredumped), libpq will now print the notice and close the connection cleanly. Formerly, the frontend app would usually terminate ungracefully due to a SIGPIPE. (I am not sure if 6.3.2 behaved that way, but the current cvs sources do...) 2. libpq's various printouts to stderr are now fed through a single "notice processor" routine, which can be overridden by the application to direct notices someplace else. This should ease porting libpq to Windows. I also noticed and fixed a problem in PQprint: when sending output to a pager subprocess, it would disable SIGPIPE in case the pager terminates early (this is good) --- but afterwards it reset SIGPIPE to SIG_DFL, rather than restoring the application's prior setting (bad). regards, tom lane

* From: Tom Lane <tgl@sss.pgh.pa.us>Marc G. Fournier1998-07-09
| | | | | | | | | | | | | | | | | | Making PQrequestCancel safe to call in a signal handler turned out to be much easier than I feared. So here are the diffs. Some notes: * I modified the postmaster's packet "iodone" callback interface to allow the callback routine to return a continue-or-drop-connection return code; this was necessary to allow the connection to be closed after receiving a Cancel, rather than proceeding to launch a new backend... Being a neatnik, I also made the iodone proc have a typechecked parameter list. * I deleted all code I could find that had to do with OOB. * I made some edits to ensure that all signals mentioned in the code are referred to symbolically not by numbers ("SIGUSR2" not "2"). I think Bruce may have already done at least some of the same edits; I hope that merging these patches is not too painful.
* Hello!Bruce Momjian1998-07-03
| | | | | | | | | | | | | | Through some minor changes, I have been able to compile the libpq client libraries on the Win32 platform. Since the libpq communications part has been rewritten, this has become much easier. Enclosed is a patch that will allow at least Microsoft Visual C++ to compile libpq into both a static and a dynamic library. I will take a look at porting the psql frontend as well, but I figured it was a good idea to send in these patches first - so no major changes are done to the files before it gets applied (if it does). Regards, Magnus Hagander
* Hi, here are the patches to enhance existing MB handling. This timeBruce Momjian1998-06-16
| | | | | | | | | | | | | | | | I have implemented a framework of encoding translation between the backend and the frontend. Also I have added a new variable setting command: SET CLIENT_ENCODING TO 'encoding'; Other features include: Latin1 support more 8 bit cleaness See doc/README.mb for more details. Note that the pacthes are against May 30 snapshot. Tatsuo Ishii

* What I've done:Bruce Momjian1998-05-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Rewritten libpq to allow asynchronous clients. 2. Implemented client side of cancel protocol in library, and patched psql.c to send a cancel request upon SIGINT. The backend doesn't notice it yet :-( 3. Implemented 'Z' protocol message addition and renaming of copy in/out start messages. These are implemented conditionally, ie, the client protocol version is checked; so the code should still work with 1.0 clients. 4. Revised protocol and libpq sgml documents (don't have an SGML compiler, though, so there may be some markup glitches here). What remains to be done: 1. Implement addition of atttypmod field to RowDescriptor messages. The client-side code is there but ifdef'd out. I have no idea what to change on the backend side. The field should be sent only if protocol >= 2.0, of course. 2. Implement backend response to cancel requests received as OOB messages. (This prolly need not be conditional on protocol version; just do it if you get SIGURG.) 3. Update libpq.3. (I'm hoping this can be generated mechanically from libpq.sgml... if not, will do it by hand.) Is there any other doco to fix? 4. Update non-libpq interfaces as necessary. I patched libpgtcl so that it would compile, but haven't tested it. Dunno what needs to be done with the other interfaces. Have at it! Tom Lane

| | | | | | | | If PQfn() receives NOTICEs from the backend, it fails because there is no provision to deal with them. This patch (supplied by Anders Hammarquist <iko@netg.se> to me as Debian maintainer of postgresql) cures the problem:
* From: Randy Kunkee <kunkee@pluto.ops.NeoSoft.com>Marc G. Fournier1998-03-15

* From: Phil Thompson <phil@river-bank.demon.co.uk>Marc G. Fournier1998-01-26
| | | | | | | | | | | | | | | | | | | I've completed the patch to fix the protocol and authentication issues I was discussing a couple of weeks ago. The particular changes are: - the protocol has a version number - network byte order is used throughout - the pg_hba.conf file is used to specify what method is used to authenticate a frontend (either password, ident, trust, reject, krb4 or krb5) - support for multiplexed backends is removed - appropriate changes to man pages - the -a switch to many programs to specify an authentication service no longer has any effect - the libpq.so version number has changed to 1.1 The new backend still supports the old protocol so old interfaces won't break.

| | | | | | | | | | | | | | | | | | | | Subject: [PATCHES] memory leak patches in libpq and psql A couple of small memory leak patches (detected with Purify) primarily in libpq. * Fixed (NULL) border problem in psql (run psql, do \m, then select something from a table...row separators will be nulls) * Fixed memory leak with the abovementioned border not being freed properly. * Fixed memory leak in freePGconn() not freeing conn->port * Fixed up PQclear() to free parts of PGresult only if these parts are not null. * Fixed a decent memory leak that occured after executing every command in psql. PGresult *results was not freed most of the time. There is still a leak being detected (2 bytes) in readline functions, but I think this is old readline library. I will install new one and test it.

| | | | | | | | | | | Hi, counting the empty dummy queries in libpq isn't everything. If the backend sends an error, the I returns from the dummies still come. So we must eat them up in any case, not just returning on the occurence of an E reply. Until later, Jan

* following is a little fix for libpq.Bruce Momjian1996-11-20
| | | | | | | | | | | | | PQexec handles the possibility of multiple results from one query by simply submitting an empty query after the first result and waiting for an 'I' message. Rules can generate errors with transaction abort after the first 'C' message was recieved (e.g. if a C-language function used in a rule calls elog(WARN, ...)). Thus we have to look for.
