* 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have attached a patch to allow GROUP BY and/or ORDER BY function or expressions. Note worthy items: 1. The expression or function need not be in the target list. Example: SELECT name FROM foo GROUP BY lower(name); 2. Simplified the grammar to use expressions only. 3. Cleaned up earlier patch in this area to make use of existing utility functions. 3. Reduced some of the members in the SortGroupBy parse node. The original data members were redundant with the new expression node. (MUST do a "make clean" now) 4. Added a new parse node "JoinUsing". The JOIN USING clause was overloading this SortGroupBy structure. With the afore mentioned reduction of members, the two clauses lost all their commonality. 5. A bug still exist where, if a function or expression is GROUPed BY, and an aggregate function does not include a attribute from the expression or function, the backend crashes. (or something like that) The bug pre-dates this patch. Example: SELECT lower(a) AS lowcase, count(b) FROM foo GROUP BY lowcase; *** BOOM *** --Also when not in target list SELECT count(b) FROM foo GROUP BY lower(a); *** BOOM AGAIN ***

* Allows the following query to succeed: "SELECT NULL ORDER BY 1;"Thomas G. Lockhart1998-08-02
| | | | | | | | | | There are three or four cases in transformSortClause() and I had fixed only one case for UNION. A second case is now fixed, in the same way; I assigned INT4OID to the column type for the "won't actually happen" sort. Didn't want to skip the code entirely, since the backend needs to _try_ a sort to get the NULLs right. I'm not certain under what circumstances the other cases are invoked and these are not yet fixed up, though perhaps they don't need to be...

Please let me know if you have further problem. P.S. I did not include pathces to configure and gram.c to save the file size(configure.in and gram.y modified).
