Bruce Momjian	f71d0cf64e	Attached is a patch to remove the definitions of libpq's internal 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.	27 years ago

Bruce Momjian	c0d730460f	The attached patch fixes a problem that I seem to have introduced with the new support for asynchronous NOTIFY in libpgtcl. With the current sources, if the backend disconnects unexpectedly then the tcl/tk application coredumps when control next reaches the idle loop. Oops. regards, tom lane	27 years ago

Bruce Momjian	583891833f	The attached patch modifies libpgtcl per previous discussion: the pg_notifies statement is eliminated, and callbacks defined by pg_listen are instead invoked automatically from the Tcl idle loop whenever a NOTIFY message is received. I have done only cursory testing, so there may be problems still lurking (particularly on non-Unix machines?). But it seems to work. Patch is against today's cvs sources. Note that this will not work with the 6.3.2 release since it depends on the new libpq. The diffs are a bit large so I've gzipped them. A patch to update libpgtcl.sgml is included too. regards, tom lane	28 years ago
Bruce Momjian	1c2d9cb637	It seems the regression tests don't cover copy in/out at all, so code that I had assumed was working had not been tested. Naturally, it was broken ... Tom Lane	28 years ago
Bruce Momjian	edbd51395c	What I've done: 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	28 years ago
Marc G. Fournier	6ac2528616	From: Randy Kunkee <kunkee@pluto.ops.NeoSoft.com> It is my hope that the following "patches" to libpgtcl get included in the next release. See the update to the README file to get a full description of the changes. This version of libpgtcl is completely interpreter-safe, implements the database connection handle as a channel (no events yet, but will make it a lot easier to do fileevents on it in the future), and supports the SQL "copy table to stdout" and "copy table from stdin" commands, with the I/O being from and to the connection handle. The connection and result handles are formatted in a way to make access to the tables more efficient.	28 years ago

Bruce Momjian	319dbfa736	Another PGINDENT run that changes variable indenting and case label indenting. Also static variable indenting.	28 years ago

Marc G. Fournier	552620c8b2	Changes to libpgtcl submitted by: wieck@sapserv.debis.de (Jan Wieck) Adds: -lAttributes Returns another format of the results attribute list. Per attribute a sublist of {{attname} atttype attlen} is returned and an empty string if no attributes where received. -numAttrs Returns the number of attributes in the result.	29 years ago
