* pg_on_connection_loss command for libpgtcl. Patch fromTom Lane2002-09-02
| | | | | | | | Gerhard Hintermayer, revised and documented by Tom Lane. This patch also fixes a 'must fix' bug: libpgtcl's LISTEN/NOTIFY support was broken by the recent changes to the PGnotify structure. Guess that change wasn't quite so safe as we thought.

I used StringInfo only in 2 places and both of them are inside debug ifdefs. Only performance penalty will come from using strlen() like all the other code does. I also modified some of the already patched parts by changing snprintf(buf, 2 * BUFSIZE, ... style lines to snprintf(buf, sizeof(buf), ... where buf is an array. Jukka Holappa

* What I have done for libpgtcl:Bruce Momjian2002-08-17
| | | | | | | | | | | | | | | | | | | | | | Everytime if I do PQconsumeInput (when the backend channel gets readable) I check for the return value. (0 == error) and generate a notification manually, e.g. fixed string connection_closed) and pass it to the TCL event queue. The only other thing I had to do is to comment out removing all pending events in PgStopNotifyEventSource whenever the connection was unexpectedly closed (so the manually generated event will not be deleted). A broken backend connection triggers a notify event to the client (fixed notification string "connection_closed") so proper action can be taken to switch to another database server etc. Remember that this is event driven. If you have applications, that have idle database connections most of the time, you'll get immediate feedback of a dying server. Upon connection to the server issue a pg_notify for notify event "connection_closed" and whenever the backend crashes (which it does do in very very rare cases) you get an event driven recovery. (of course the Tcl-Event loop has to be processed). Issuing a notification "connection_closed" on a still working database could be used for switching to another db-server (which I've actually impelemented right now). Gerhard Hintermayer

* Restructure the key include files per recent pghackers discussion: thereTom Lane2001-02-10
| | | | | | | | | | | are now separate files "postgres.h" and "postgres_fe.h", which are meant to be the primary include files for backend .c files and frontend .c files respectively. By default, only include files meant for frontend use are installed into the installation include directory. There is a new make target 'make install-all-headers' that adds the whole content of the src/include tree to the installed fileset, for use by people who want to develop server-side code without keeping the complete source tree on hand. Cleaned up a whole lot of crufty and inconsistent header inclusions.

* Change PQconndefaults() to return a malloc'd array, instead of a staticTom Lane2000-03-11
| | | | | | | | array. This allows processing of conninfo strings to be made thread-safe, at the cost of a small memory leak in applications that use PQconndefaults() and are not updated to free the returned array via the new PQconninfoFree() function. But PQconndefaults() is probably not used very much, so this seems like a good compromise.

* This patch covers several to-do items that I had for libpgtcl:Bruce Momjian1998-09-21
| | | | | | | | | | | | | | | | | | | | | | | * It works under both Tcl 7.6 and Tcl 8.0 now. (The code claims to work under Tcl 7.5 as well, but I have no way to test that --- if anyone still cares, please check it with 7.5.) * pg_listen suppresses extra LISTEN commands and correctly sends an UNLISTEN when the last listen request for a relation is cancelled. (Note this means it will not work with pre-6.4 backends, but that was true already because it depends on the current libpq, which only speaks protocol 2.0.) * Added -error option to pg_result so that there's some way to find out what you did wrong ;-) * Miscellaneous cleanups of code comments and overenthusiastic #includes. BTW, I bumped the package version number from 1.2 to 1.3. Is this premature? Does someone run around and do that routinely before each pgsql release? regards, tom lane

* Attached is a patch to remove the definitions of libpq's internalBruce Momjian1998-09-03
| | | | | | | | | | | | | | | | | 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.

* From: Tom Lane <tgl@sss.pgh.pa.us>Marc G. Fournier1998-07-09
| | | | | | | | | | | | | | | | | | | | | | | | The attached patches respond to discussion that was on pgsql-hackers around the beginning of June (see thread "libpgtcl bug (and symptomatic treatment)"). The changes are: 1. Remove code in connectDB that throws away the password after making a connection. This doesn't really add much security IMHO --- a bad guy with access to your client's address space can likely extract the password anyway, to say nothing of what he might do directly. And there's the serious shortcoming that it prevents PQreset() from working if the database requires a password. 2. Fix coredump problem: fe_sendauth did not guard against being handed a NULL password pointer. (This is the proximate cause of the coredump- during-PQreset problem that Magosanyi Arpad complained of last month.) 3. Remove highly questionable "error recovery" logic in libpgtcl's pg_exec statement. I believe the consensus of the discussion last month was in favor of #1 and #3, but I'm just now getting around to making the change. I realized that #2 was a bug in process of looking at the change.
