* Add resetStringInfo(), which clears the content of a StringInfo, andNeil Conway2007-03-03
| | | | | | fixup various places in the tree that were clearing a StringInfo by hand. Making this function a part of the API simplifies client code slightly, and avoids needlessly peeking inside the StringInfo interface.

* Tweak the behavior of log_duration as proposed by Guillaume Smet: ratherTom Lane2006-09-08
| | | | | | | than being equivalent to setting log_min_duration_statement to zero, this option now forces logging of all query durations, but doesn't force logging of query text. Also, add duration logging coverage for fastpath function calls.

* Allow include files to compile own their own.Bruce Momjian2006-07-13
| | | | | | | Strip unused include files out unused include files, and add needed includes to C files. The next step is to remove unused include files in C files.

* Do a CHECK_FOR_INTERRUPTS immediately before terminating a fastpathTom Lane2006-06-14
| | | | | | | | | function call. Previously, there may have been no CHECK_FOR_INTERRUPTS at all in the fastpath code path, making it impossible to cancel an operation such as \lo_import externally. This addition doesn't ensure you can cancel, since your SIGINT may arrive while the backend is idle waiting for the client, but it gives the largest window we can easily provide. Noted while experimenting with new control-C code for psql.
* Fix Assert failure when a fastpath function call is attempted inside anTom Lane2006-06-11
| | | | | | | | | | | | | | | already-aborted transaction block. GetSnapshotData throws an Assert if not in a valid transaction; hence we mustn't attempt to set a snapshot for the function until after checking for aborted transaction. This is harmless AFAICT if Asserts aren't enabled (GetSnapshotData will compute a bogus snapshot, but it doesn't matter since HandleFunctionRequest will throw an error shortly anywy). Hence, not a major bug. Along the way, add some ability to log fastpath calls when statement logging is turned on. This could probably stand to be improved further, but not logging anything is clearly undesirable. Backpatched as far as 8.0; bug doesn't exist before that.
* Modify all callers of datatype input and receive functions so that if theseTom Lane2006-04-04
| | | | | | | | | | | | | | | functions are not strict, they will be called (passing a NULL first parameter) during any attempt to input a NULL value of their datatype. Currently, all our input functions are strict and so this commit does not change any behavior. However, this will make it possible to build domain input functions that centralize checking of domain constraints, thereby closing numerous holes in our domain support, as per previous discussion. While at it, I took the opportunity to introduce convenience functions InputFunctionCall, OutputFunctionCall, etc to use in code that calls I/O functions. This eliminates a lot of grotty-looking casts, but the main motivation is to make it easier to grep for these places if we ever need to touch them again.

* Re-run pgindent, fixing a problem where comment lines after a blankBruce Momjian2005-11-22
| | | | | | | | | comment line where output as too long, and update typedefs for /lib directory. Also fix case where identifiers were used as variable names in the backend, but as typedefs in ecpg (favor the backend for indenting). Backpatch to 8.1.X.

* Suppress signed-vs-unsigned-char warnings.Tom Lane2005-09-24

* Change typreceive function API so that receive functions get the sameTom Lane2005-07-10
| | | | | | | optional arguments as text input functions, ie, typioparam OID and atttypmod. Make all the datatypes that use typmod enforce it the same way in typreceive as they do in typinput. This fixes a problem with failure to enforce length restrictions during COPY FROM BINARY.
* Change CREATE TYPE to require datatype output and send functions to haveTom Lane2005-05-01
| | | | | | | only one argument. (Per recent discussion, the option to accept multiple arguments is pretty useless for user-defined types, and would be a likely source of security holes if it was used.) Simplify call sites of output/send functions to not bother passing more than one argument.
* Officially decouple FUNC_MAX_ARGS from INDEX_MAX_KEYS, and set theTom Lane2005-03-29
| | | | | | former to 100 by default. Clean up some of the less necessary dependencies on FUNC_MAX_ARGS; however, the biggie (FunctionCallInfoData) remains.
* Convert oidvector and int2vector into variable-length arrays. ThisTom Lane2005-03-29
| | | | | | | | | | | | | change saves a great deal of space in pg_proc and its primary index, and it eliminates the former requirement that INDEX_MAX_KEYS and FUNC_MAX_ARGS have the same value. INDEX_MAX_KEYS is still embedded in the on-disk representation (because it affects index tuple header size), but FUNC_MAX_ARGS is not. I believe it would now be possible to increase FUNC_MAX_ARGS at little cost, but haven't experimented yet. There are still a lot of vestigial references to FUNC_MAX_ARGS, which I will clean up in a separate pass. However, getting rid of it altogether would require changing the FunctionCallInfoData struct, and I'm not sure I want to buy into that.
* Tag appropriate files for rc3PostgreSQL Daemon2004-12-31
| | | | | | | | Also performed an initial run through of upgrading our Copyright date to extend to 2005 ... first run here was very simple ... change everything where: grep 1996-2004 && the word 'Copyright' ... scanned through the generated list with 'less' first, and after, to make sure that I only picked up the right entries ...
* Redesign query-snapshot timing so that volatile functions in READ COMMITTEDTom Lane2004-09-13
| | | | | | | | | | | | | mode see a fresh snapshot for each command in the function, rather than using the latest interactive command's snapshot. Also, suppress fresh snapshots as well as CommandCounterIncrement inside STABLE and IMMUTABLE functions, instead using the snapshot taken for the most closely nested regular query. (This behavior is only sane for read-only functions, so the patch also enforces that such functions contain only SELECT commands.) As per my proposal of 6-Sep-2004; I note that I floated essentially the same proposal on 19-Jun-2002, but that discussion tailed off without any action. Since 8.0 seems like the right place to be taking possibly nontrivial backwards compatibility hits, let's get it done now.

* Infrastructure for I/O of composite types: arrange for the I/O routinesTom Lane2004-06-06
| | | | | | | | | | of a composite type to get that type's OID as their second parameter, in place of typelem which is useless. The actual changes are mostly centralized in getTypeInputInfo and siblings, but I had to fix a few places that were fetching pg_type.typelem for themselves instead of using the lsyscache.c routines. Also, I renamed all the related variables from 'typelem' to 'typioparam' to discourage people from assuming that they necessarily contain array element types.
* Complete TODO item:Bruce Momjian2004-04-19
| | | | | | | | | | | | | | o -Allow dump/load of CSV format This adds new keywords to COPY and \copy: CSV - enable CSV mode (comma separated variable) QUOTE - specify quote character ESCAPE - specify escape character FORCE - force quoting of specified column LITERAL - suppress null comparison for columns Doc changes included. Regression updates coming from Andrew.
* More janitorial work: remove the explicit casting of NULL literals to aNeil Conway2004-01-07
| | | | | | | | pointer type when it is not necessary to do so. For future reference, casting NULL to a pointer type is only necessary when (a) invoking a function AND either (b) the function has no prototype OR (c) the function is a varargs function.

* Error message editing in backend/libpq, backend/postmaster, backend/tcop.Tom Lane2003-07-22
| | | | | Along the way, fix some logic problems in pgstat_initstats, notably the bogus assumption that malloc returns zeroed memory.
* Now that fastpath protocol allows null arguments to be passed,Tom Lane2003-05-09
| | | | fastpath.c had better check for strict functions.
* Implement new-protocol binary I/O support in DataRow, Bind, and FunctionCallTom Lane2003-05-09
| | | | | messages. Binary I/O is now up and working, but only for a small set of datatypes (integers, text, bytea).
* Update 3.0 protocol support to match recent agreements about how toTom Lane2003-05-08
| | | | | | | 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.
* Extended query protocol: parse, bind, execute, describe FE/BE messages.Tom Lane2003-05-05
| | | | Only lightly tested as yet, since libpq doesn't know anything about 'em.
* Portal and memory management infrastructure for extended query protocol.Tom Lane2003-05-02
| | | | | | | | | Both plannable queries and utility commands are now always executed within Portals, which have been revamped so that they can handle the load (they used to be good only for single SELECT queries). Restructure code to push command-completion-tag selection logic out of postgres.c, so that it won't have to be duplicated between simple and extended queries. initdb forced due to addition of a field to Query nodes.
* Another round of protocol changes. Backend-to-frontend messages now allTom Lane2003-04-22
| | | | | | | | | | 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.
* Second round of FE/BE protocol changes. Frontend->backend messages nowTom Lane2003-04-19
| | | | have length counts, and COPY IN data is packetized into messages.
* Move new typedef AclId into c.h, so as to avoid cluttering namespaceTom Lane2003-01-09

* fastpath code neglected to check whether user has privileges to call theTom Lane2003-01-01
| | | | | target function. Also, move SetQuerySnapshot() call to avoid assert failure when a fastpath call is attempted in an aborted transaction.
* The cstring datatype can now be copied, passed around, etc. The typlenTom Lane2002-08-24
| | | | | | | value '-2' is used to indicate a variable-width type whose width is computed as strlen(datum)+1. Everything that looks at typlen is updated except for array support, which Joe Conway is working on; at the moment it wouldn't work to try to create an array of cstring.

* Remove fastpath.c's lame attempt at caching function lookup info acrossTom Lane2001-06-01
| | | | | | | | | calls. This has never actually cached anything, because postgres.c does each fastpath call as a separate transaction command, and so fastpath.c would always decide that its cache was outdated. If it had worked, it would now be failing for calls of oldstyle functions due to dangling pointers in the FmgrInfo struct. Rip it out for simplicity and bug- proofing.
