I'm planning to implement a new PostgreSQL DBI driver with prepare support, but paying work has come between me and that project. It's going to be a while before I can get back to it, I think. Meanwhile, you can use DBD::Pg and its prepare method, and when I finally get around to writing the new driver, you should be able to upgrade without much difficulty.

Back over Thanksgiving, I kludged together a proof of concept 'DBD::ChurlPg' that does serverside prepare() for DML statements [among some other things that I wanted.] I did this for myself, so I was not going to show it to anyone, but what the heck. If you are intersted in taking a look, the code is here: http://www.remotelinux.com/rlippan/ There is some uglyness in there and rows() is broken (it is using default from driver.xst), but otherwise it has been working for me for the past few months. I'd love to get some feedback on the changes that I made. And if wanted (read other's will think that the changes are useful), I will clean up the code and port the changes over to the latest version of DBD::Pg. -r

The patch can be found here: http://www.remotelinux.com/rlippan/dbd_pg.patch (I did not include it in this email because I did not want to spam everyone with a 100K diff). I'd like to start putting together some developer releases (set up a cvs branch for this?), and see about getting together a stable release version that addresses the all of the outstanding problems with DBD::Pg. So, if people are interested, where do I go from here to get things set up for doing dev releases &c.? What the patch does: 1. $dbh->prepare() rewrites the SQL statement into an internal for striping out comments and whitespace, and if PostgreSQL> 7.3 takes the stripped statement and passes that to postgress' PREPARE statement, then rewrites the statement as 'EXECUTE "DBD::PG::cached_queryn" ($1, $2, ... $n, $n+1)' for DBD::Pg's execute. 2. Allows the use of :n and :foo bind params. So: (SELECT * FROM foo where 1 = :this and 2 = :that) will now work. 3. Complains on execute when unbound bind params are submitted (instead of defaulting to NULL) 4. Switched over to use driver.xst. 5. pg_error() only removes \n's don't truncate message on first \n 6. fixed statement scan problem where the preparse of "SELECT foo[3:33] from bar" was scanning :33 as a placeholder 7. moved the quoting of bind values out of execute() and into bind -- as there is no need to requote the value every timeexecute is called. 8. :veryverylongplaceholdername == Long walk. Sort pier -- fixed. 9. quote() is now in C and uses same code as bind_param. 10. quoting and dequoting now use libpq quoting functions where available (I still need to take the libpq functionsswiped out of quote.c and move it into libpqswip.c with license info &c., and switch ifndefs to ifdefs) 11. bind_param() will convert from 1,0 to TRUE/FALSE when pg_type is PGBOOLOID. 12. fixed many heap buffer overruns. Known problems with patch: 1. Broke new pg_bool_tf attribute. 2. Broke rows() method (Just needs a define in makefile) 3. quote("stuff", {typeinfo }) is broken (only when hashref is passed in) 4. broke chopblanks. 5. has some // style comments around debug statements that need to be converted into logging statements 6. PREPARE is not bullet-proof casts in RSH of equality and functions LHS of equality can break serverside prepare, sodecide exactly how to do this and how to get prepares of INSERT statements to work? Move prepqre to execute and buildlist column list in bind_param? Add attributes to prepare to identify the columns and serverside prepare if theyexist? 7. Code is not as clean as it should be -- some kludgeness in there. 8. Documentation has not been updated. 9. Needs more tests. On my immediate todo list: 1. Change quote and dequote functions to take Sv instead of string so that things like arrays can be seralized by the quotefunction. This will take care of broken chopblanks and pg_bool_tf (pass the quote/dequote options struct to functionquote/dequote functions). 2. Export the full list of supported OID types. 3. finish all type mappings in types.c 4. supoort for begin_work() method. 5. clean logging and trace levels. 6. dblogin to handle user names, table table names and other names that containg ';'s 7. add attributes to control preparing of statements. 8. rewrite hacked version detection code (and get format for string so it is done correctly with patch level &c.). 9. various code cleanups and polishing. 10. Copy over external test cases from DBD::Churlpg and write more tests. 11. Update documentation. There are probably many other things that I cannot remember off the top of my head since I have not done much (other than copy code over to CVS head) with this code since late Nov/ early Dec. -r

No need for a separate branch, I think. Just change the version number to have an undersore, e.g., 1.30_01.

Still, it's a lot of work. I had no idea you'd done this, Rudy. I suspect that once you get this committed, others will contribute, as it represents the first real advances in DBD::Pg in years.

I was thinking more for bug fixes agaist the old version before the
devel release are tested enough to go to production.
As for CPAN, should I go ahead set up a PAUSE account (I need to anyway)
for making the dev release, or do you want to handle making the releases?
(I warn you, though, that I am planing on releasing quite often until I
get a release that is stable enough for a production environment ;) ) If
the former what would need to be done to get CPAN to pick up my uploads as
part of DBD::Pg?
I signed up for the DBD::Pg project on gborg.org few days ago, so what do
I need to do to get CVS commit access?

I think that the docs say that it does not work, but the code (from
DBD::oracle) was still there in preparse and bind, so it would work up
until execute() where it would break because execute was not looking for
:foo style placeholders.
This version saves the values for placeholer 1..n in an array and just
uses the key :foo as a lookup for the index into that array.

Probably. But the big win is that it uses the same quoting code that
bind_param does; therefore, they both use the libpq quoting function.

Yup. But they are not in the patch.

Yeah. This just comes about because the way I implemented quoting. There
is a struct of pq_types that contains pointers to quote and dequote
functions. Right now the quote and dequote functions don't know anything
about perl/dbi... "Take string send to libpq return string returned from
libpq."

These are the calls that are broken: quote(foo, {type=>SQL_INTEGER}) quote(foo, {pg_type=>DBD::Pg::PG_INTEGER})
Which I do see being used. So this fix is at the top of my list.

Yes. PostgreSQL's PREPARE wants a list of column types when you call
prepare, so as proof of concept I did a (varchar, varchar, varchar...) for
the column types, but that ends up breaking some things (like UPDATE
INSERT, and when it checks an operation for castability).
Which does not make sense to me... postgres knows the fields types why
does it not set them correctly instead of making the application
programmer enumerate them... (or maybe give a type that causes pg to
not do checking. -- pg does the checks twice once on prepare and then it
does them again on execute, so again why not just sub in the correct types
if nothing was enumerated beforhand on prepare and let the checks on
execute handle the type checks?. Or am I missing something? Grr.

I know, those might be easier for the user, but for all interal stuff, I
am using the ones extraced from pg header files:
grep '^#define' /data/dnloads/postgresql-7.3/src/include/catalog/pg_type.h
|grep OID >pg_typeOID.h
And I think that they should be available to the perl programmer as well.

Oh, well we can create a branch for the old version. Bruce, do you have
a CVS tag convention that you like to use?

Either way. I can give you ownership if you like, but even if I don't
you can still upload releases. Let me know your preference.

Makes sense.

Yes. DBI::DBD says that dbdimp.h in part
defines macros that rename the generic names like dbd_db_login to database specific names like
ora_db_login.This avoids name clashes and enables use of different drivers when you work with a statically linked
perl.

Tom has made some mumblings about making this easier, but I don't know
if anything has been done. But I was under the assumption that if you
used "text" for the data types that they would be cast without too much
trouble.

To answer your question from a month ago :-), we should have CVS tagged the 1.21 release, but we forgot. I didn't think we were big enough to tag things. :-) We don't have any master plan on development --- we just discuss items and apply patches. --------------------------------------------------------------------------- Rudy Lippan wrote: > On Thu, 13 Feb 2003, Dominic Mitchell wrote: > > > Well at the moment, backwards compatibility is limited to one system at > > our place that needed the funtionality right now.

Bruce,
To respond to your message of a week or so ago :-)
I tagged it up a while ago -- Just so that I can keep myself sane.
I also created a Dev-1_3 branch because my patch conflicted with the array
patch that you merged [more on that later]. Anyway I applied my patch on
the Dev-1_3 branch -- I did this because it conflicted with the uft_8 patch
and I think there was some interest in putting out a utf enable release
before 1_3.
One thing to note about the Dev-1_3 tree I disabled the server-side
prepare of statements because what I was doing to hack them in was causing
more problems that it was was worth. If we can get a clean way for the
server to prepare statements, I will re-enable server-side prepares, and I
don't think that bind_param(":foo", 1, {type=>'varchar'}) is the way to
go. So, Basically what I am want is for the server to either 1. ignore
the type checking and only do that at execute time, or 2. give me a list of
types. This should not be to
Now, about the array patch in cvs: I looked it over and I don't
particularly like it for a couple of reasons: 1. the av_shift() and
av_clear() modify the array that was passed in, so if you pass in an
array, all of the data in your array will vanish. 2. escaped quotes can
confuse things 3. isn't sv_catpv a bit expensive to be used there, why not
just malloc what is needed before escaping the string? 4. It conflicts
with the direction I was moving WRT quoting :-) take a look at the way
that Dev-1_3 handles quoting. To do the array quoting I am thinking about
making the quote_* functions take an SV and the dequote_* functions return
an SV. :) 5. The patch does not handle dequoting of arrays.
I have been sitting on getting a developer release out for a little while
now, and I would like to get that out, so that I can get some feed back
and move forward with the other things that I want to get working (like
array quoting/dequoting, full UTF8 support, begin_work(),
quote_identifier, &c.)
Actually, what I have been sitting on is getting a PAUSE ID, which I just
requested :-)
Later,
Rudy.
These all sounds good. Can I get some of them as patches I can apply
now --- having one megapatch usually gets too complex after a while.

I am confused? I thought the plan was to relase a version of DBD::Pg
basied on the 1_21 release with UTF-8 support and then merge in the
patch. This is the reason why I did not apply the mega patch against
HEAD.
So I guess what I am propsing is get 1.22 out (if we even think it is
needed -- I think that we can just get away with putting the UTF-8 stuff
off until 1.3) and then drop Dev-1_30 over HEAD 1_21, then apply
the subsequent patches over that.
Thoughts?

OK, so you are saying that the code as exists now in CVS is ready for release, and once we release, you want to add a lot of stuff, right?

Bruce, 1.21 + UTF-8 patch should be ready to be released as 1.22. We can skip putting up a 1.22 and jump right to 1.30 alpha if we don't see a need for getting out the UTF patch? I am easy on this point. So do we want a 1.22 or do we want to jump right to a 1.30 alpha? The 'a lot of stuff' is already in CVS on the 1_30 branch. I put it there because I thought we were going to be releasing a 1.22 for basic UTF support, but since then CVS head has gathered a few other patches that are not ready for release :( What I am planing on doing is copying 1_30 over cvs head, making an alpha release based on that, and then merging all of the patches that were added since 1.21. (And all new patches against CVS head will be easier to apply). The patch that is on the 1_30 branch is here: ftp://gborg.postgresql.org/pub/dbdpg/1/dbd_pg.patch and I think it would be much easier to merge a few minor patches rather than the other way around :) Thoughs?

Maybe noone will notice ;) Anyway, I will get 1.30 up onto CVS head on the morrow (well later today, now), and we can start working form there ( And 1.30 fixes those pesky segfaults that got commented in 1.22 :) Although, it might add others :( ) Later, Rudy

What version of perl do you have? I have 5.005_03, and others have 5.6,
and both seem to work. The current test in dbdimp.c is:#ifdef SvUTF8_off if (imp_dbh->pg_enable_utf8) {

==type|| 1043 == type) { if (is_high_bit_set(val) && is_utf8_string(val, val_len)) SvUTF8_on(sv);
} }#endif
Maybe that isn't the right test --- maybe you have a version of perl
that passes the #ifdef test, but doesn't have is_utf8_string().

I have perl 5.6.0. I don't know if it has is_utf8_string()... Where would I

I'm fuzzy on the details but ISTR Perl 5.6.0 was not one of Perl's better
releases and was replaced fairly quickly with 5.6.1. A bit of googling
returns is_utf8_string() together with 5.6.1 but no references to 5.6. This
is not scientific evidence though.
Can you do "perldoc perlapi" with 5.6.0? If so the presence / absence
of is_utf8_string() should solve the problem.

Yep, there is no trace of is_utf8_string() in perldoc perlapi for 5.6.0
Does this mean that my only option is to upgrade perl? Or will the module
still work without it?
Thanks for your help

You can either upgrade perl to 5.6.1 or, if you don't want to upgrade perl, you can dike out the section of code between the #ifdef and #endif and then it should work (might fail some UTF-8 test). I would recommed upgrading perl, however. -r

So much has changed in there that I am sure something is broken for someone; therefore, I think we should let people hammer on it for a few days before making an official release. I put the alpha up here: http://www.remotelinux.com/rlippan/DBD-Pg-1.30_1.tar.gz And for anyone who is interested here is the change log: - $dbh->prepare() rewrites the SQL statement into an internal for striping out comments and whitespace, and if PostgreSQL> 7.3 takes the stripped statement and passes that to postgress' PREPARE statement, then rewrites the statement as 'EXECUTE "DBD::PG::cached_queryn" ($1, $2, ... $n, $n+1)' for DBD::Pg's execute. -- Currently disabled until PREPARE works a little better - Allows the use of :n and :foo bind params. So: (SELECT * FROM foo where 1 = :this and 2 = :that) will now work. - Complains on execute when unbound bind params are submitted (instead of defaulting to NULL) - Switched over to use driver.xst. - pg_error() only removes \n's don't truncate message onfirst \n - fixed statement scan problem where the preparse of "SELECT foo[3:33] from bar" was scanning :33 as aplaceholder - moved the quoting of bind values out of execute() and into bind -- as there is no need to requote thevalue every time execute is called. - :veryverylongplaceholdername == Long walk. Sort pier -- fixed. - quote()is now in C and uses same code as bind_param. - quoting and dequoting now use libpq quoting functions where available (I still need to take the libpq functions swiped out of quote.c and move it into libpqswip.c with license info &c., and switch ifndefs to ifdefs) - bind_param() will convert from 1,0 to TRUE/FALSE when pg_type is PGBOOLOID. - fixed many heap buffer overruns.

Hopefully implemented as
if (DBIc_WARN(imp_xxh)) warn("...", ...)
The $h->{Warn} attribute defaults to true. Can be useful to silence
warnings for a handle without having to play games with $SIG{__WARN__}.

See, I told you I wasn't an XS guru. :-)
Actually, I looked at this, but my limited C and DBI skills couldn't
work out a) what the required handle was (probably dbh) and b) how to
pass that into the PQsetNoticeProcessor function as data and get it out
again.
I'll happily take another look though, now that it's been brought up as
desirable.

Just whatever handle was used to call the method that's generating the warning.

Ah, different issue. For that I'd say if DBIc_WARN(imp_xxh) isn't true
then disable the PQsetNoticeProcessor function.

Actually I'd misunderstood the circumstances of the warn (not reading
your message carefully enough). For notice messages generated by
the database server they'll soon(ish) be a $h->{HandleEvent} = sub { ... }
hook that should be used.
But that'll bring you back to needing some way for the PQsetNoticeProcessor
function to get at the handle data it'll need to pass to the HandleEvent
hook. The PQsetNoticeProcessor API ought to allow you to some way to do that.

Well, we're calling PQsetNoticeProcessor[1], from inside dbd_db_login,
so I should be able to pass in imp_dbh as the "arg" argument. The bit
that I wasn't sure about before was what to cast it to in order to
retrieve it from a void *.

How will that work? Is that for any sort of asynchronous message from
the database?

It does, I just couldn't figure it out in the 30 minutes I spent looking
at it. I need to go back and spend more time with the docs and less
being lazy. :-)

You could always cast it to a void * :-)

That kind of thing, yes, plus 'success with info' and anything else
a driver wants to comminucate back to an app 'out of band'. The
tricky part will be categorizing the types of events to make it
usefully portable. But I don't want to start that thread just yet,
so ignore me!
