Thread: Re: [COMMITTERS] pgsql: Allow psql multi-line column values to align
OK, I have applied your patch to psql and Teodor has adjusted the tsearch2 expected results. I can't seem to run pgcrypto without getting PRNG errors, so I expect my SSL is too old. Would you send me your pgcrypto/regression.diff? Thanks. --------------------------------------------------------------------------- Kris Jurka wrote: > > > On Thu, 9 Feb 2006, Bruce Momjian wrote: > > > Log Message: > > ----------- > > Allow psql multi-line column values to align in the proper columns > > > > There is a problem with this on AIX. > > http://pgbuildfarm.org/cgi-bin/show_log.pl?nm=asp&dt=2006-02-10%2006:23:00 > > For tables that have no columns AIX thinks it has an out of memory error. > src/bin/psql/print.c:pg_local_calloc bails out if calloc returns NULL.

I fixed that already. Please see about fixing the compiler warnings you
introduced. On a 64-bit machine there are even more, and the int vs
size_t ones are definitely portability problems.

I submitted this patch so long ago I figured it'd gotten lost. I was actually considering preparing a new version against HEAD.

You'd need a newer compiler.

I'm currently merging CVS with my version and getting a lot of conflicts (whitespace variations). It's fairly simple changes AFAICS. Just need to fix the declarations of a few variables. -- Martijn van Oosterhout <kleptog@svana.org> http://svana.org/kleptog/ > Patent. n. Genius is 5% inspiration and 95% perspiration.

Does PostgreSQL have a policy on the signedness of strings? When I was making the patch I generally used "unsigned char" to try to emphasise that these are not characters, they are bytes of an encoding. But this doesn't play well with existing functions like PQdsplen and PQmblen. At this point I'm thinking of dropping the "unsigned" everywhere and just being really careful of comparisons. OTOH, it's really those two functions being inconsistant because the underlying functions do use unsigned. Thoughts?

For the most part we say "char" where we can and "unsigned char" only
where it really matters, which is mostly inside code that's
encoding-aware anyway.
It was only fairly recently that we cleaned the code up to avoid
signedness warnings, but now that that's done I don't want to backtrack
on it. What I'd suggest is taking a close look at the set of functions
you have and trying to identify a layer that should be "unsigned char"
versus upper layers that can just say "char".

Well, I've done this and avoided changing any public interfaces. ie the libpq interface remains unsigned, as does the psql formatting code, but the printTable stuff only is for the parts that actually do formatting...

Applied with some cosmetic cleanups and further fixes for 64-bit
problems.
