Reintroduce fixes for unary minus parsing with leading spaces.
|
|
Check for and properly ignore FOREIGN KEY column constraints
(already had fixed same for table constraints).
Define USER as synonym for CURRENT_USER per SQL92 specs
(no longer allowed as bare column name, sorry).
Re-enable HAVING clause but no fixes elsewhere yet.
Other stuff from today's update of gram.y...

Re-enable HAVING clause but no fixes elsewhere yet.
Make "char" type a synonum for "char(1)" (actually implemented as bpchar).
Compress/compact row-style subselect and operator definitions
(cut out ~140 lines of code with no change in functionality).
Save string type if specified for DEFAULT clause handling.
Enough for now...

code that I had assumed was working had not been tested. Naturally,
it was broken ...

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!

- Put operator "->" back into parser. Note that :foo->bar means the
C term, but :foo ->bar means the operator "->".

- Added exec sql disconnect command.
- Allow varchar in C to be written in uppercase too.
- Added whenever option "do break;"
Wed Apr 29 09:17:53 CEST 1998
- Corrected parsing of C comments.
- Also allow C++ style comments.
- Make sure not found is only checked after commands that could
return it.
- Added error codes, see ecpgerror.h for details.
- Added "exec sql <TransactionStmt> release" as disconnect statement
for compatibility issues.
Thu Apr 30 10:42:10 CEST 1998
- Added a -t option to disable automatic transaction start.
- Added sqlerrd[] to sqlca struct.
- Give back number of tuples affect in sqlca.sqlerrd[2].
Thu Apr 30 13:36:02 CEST 1998
- Make the return code different in case of different errors.
Wed May 6 11:42:48 CEST 1998
- Free memory if possible
- Some bugfixes for bugs I found while changing the memory
allocation code
- Now able to fill complete array with one call (see test1.pgc for
an example)

Attached patch will add a version() function to Postges, e.g.
template1=> select version();
version

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:
