Yes, it missed the code freeze cutoff and the bug fix cutoff. Next
release try to get the new version announced at least a couple of weeks
before the nominal release date, and a month before would be even
better. Should be in v6.4.1 but I don't think anyone has committed it
yet.

I don't think that's the right approach. libpgtcl doesn't depend on
libcrypt. libpq does, and that's where we need to fix this, or else
we'll see the same problem with any other shared library that depends
on libpq.
Would you check whether it works to add the following patch to
src/interfaces/libpq's Makefile, and then build libpgtcl *without*
a reference to crypt? (I can't test it here since crypt is part of
libc on my machine...)

Completely delete postgresql from my machine and any trace of libpq and
libpgtcl
Untarred the 6.4 final distribution
apply the patch
compiled from scratch
installed
Got :
[teo@teo teo]$ Error in startup script: couldn't load file

When modify the Makefile from libpgtcl adding -lcrypt , recompile,
install . Everything it's ok.

Odd. Perhaps your system doesn't support libraries referring to other
shared libraries? (Seems unlikely, but...) In that case you'd be
getting the static libpq.a bound into libpgtcl.so, minus crypt of
course, and then this would happen.
If that's what's happening you should easily be able to tell from the
sizes of libpgtcl.so and libpq.so. On my machine, libpgtcl is actually
smaller than libpq (about half as big, in fact). If libpq is getting
bound into libpgtcl.so then libpgtcl.so would have to be bigger than
libpq.so. Which one is bigger on your machine?
Also, do you have any sort of utility that shows directly what a
program's shared library requirements are? For example, on HPUX
I can do
$ chatr /usr/local/pgsql/bin/pgtclsh
/usr/local/pgsql/bin/pgtclsh:
shared executable
shared library dynamic path search:
SHLIB_PATH disabled second
embedded path enabled first /usr/local/pgsql/lib
shared library list:
static pgtclsh
dynamic ../../interfaces/libpgtcl/libpgtcl.sl
dynamic ../../interfaces/libpq/libpq.sl
dynamic /usr/lib/libdld.sl
dynamic /lib/libcurses.sl
dynamic /lib/libc.sl
shared library binding:
deferred
$ chatr /usr/local/pgsql/lib/libpgtcl.sl
/usr/local/pgsql/lib/libpgtcl.sl:
shared library
shared library list:
dynamic ../libpq/libpq.sl
On Linux I think the corresponding command is "ldd".

Yes. libpgtcl is bigger than libpq
But ldd shows that libpq is statically linked :-( . Maybe this is the

Well, that's pretty interesting. Evidently you were able to persuade
the linker to dynamically link libpgtcl.so to libcrypt.so, but the patch
I suggested did *not* persuade the linker to dynamically link libpq.so
to libcrypt.so. Just exactly what change did you make in libpgtcl's
Makefile, anyway? I assumed it was simply adding -lcrypt, but now I
am not so sure.
It's also curious that libpq.so is not showing any dynamic dependency
on libc. I think we must have the wrong linker options for libpq.

And we also need to figure out why the linker is including libpq.a into
libpgtcl.so, instead of creating a dynamic link from libpgtcl.so to
libpq.so like it did for libcrypt and libc.
(BTW, do you have a libcrypt.a in /lib, or just libcrypt.so?)
It seems clear from your ldd results that your machine is capable of
doing the right thing, but we aren't invoking the linker with the right
options. Where I want to get to is:
libpgtcl.so: dynamic dependency on libpq.so (and libc of course)
libpq.so: dynamic dependency on libcrypt.so (and libc of course)
It might be worth extracting the part of the "make all" log that shows
what commands are being used to build each of these libraries.

No no, that change was intended to be applied to libpq's Makefile *not*
libpgtcl's. Sorry if I wasn't clear.
There's also the question of why the linker is making a dynamic
dependency on libc for libpgtcl but not libpq. Oliver suggested
that -lc is needed as well as -lcrypt in the link step, but that
doesn't seem to explain all the facts --- libpgtcl doesn't have
-lc, and it seems to be getting built right. Still, you might try
adding -lc to SHLIB_LINK in libpq's Makefile, and see if that
changes the ldd result.

Sergio,
be patient. Jan Wieck is working on patch for support LIMIT in select query.
I'm using his patch (trial 2) with 6.4 and it works great for me.
With this patch you can limit output using LIMIT offset,count statement.
Hope, this patch will come to 6.4.1.

Oleg

This is a problem only with systems running glibc, because for legal reasons the FSF doesn't want to include encryption as part of glibc. I assume you are doing this on Debian or on Red Hat 5.x? Perhaps we need an extra template for glibc? I came across this problem too today (I am currently packaging 6.4 into an RPM for Red Hat 5.2). I have generated a patch file which fixes the lack of -lcrypt in a number of places for glibc systems. After I have thoroughly tested it I'll try to post it here. > Also, PgAccess version that has been included in 6.4 final version is > 0.90 , but current stable version is 0.91 > (ftp://ftp.flex.ro/pub/pgaccess/pgaccess-0.91.tar.gz) Thanks for the pointer.

You can get the current code from the Postgres CVS server --- see http://www.postgresql.org/docs/faq-cvs.shtml.

Is this an alternative to the RedHat packaging, or are you using the
same layout and RPM setup that the RedHat 6.3 package had? Just curious;
I've been thinking about trying to help with RPM support but would be
happy that someone else is looking after it.
btw, we are currently looking at a date/time peculiarity in Postgres
with glibc2 which gives funny results for at least one test case. You
might want to stay in touch so we can fix that up for you also, once we
have a good workaround.
Actually, we should also test with RH5.2 to make sure the date/time
problem is still present, since it may have been due to a problem in
glibc2 which has since been fixed. I'm only running RH4.2 and RH5.1 so
can't directly test that myself...

I'll see if I can do that, but be forewarned that I will not be able to actually run the "current" Postgres sources in order to actually test it. I am working on a database application, not on Postgres, and I have to maintain a stable Postgres on my development machine. The reason I'm working on the 6.4 RPM for Red Hat 5.2 is for deployment purposes, not for testing purposes, though of course I'll test it before deploying it. (I want the latest stable version possible for deployment, because once deployed, it will be out there for a LONG time). BTW, congrats to everybody on an excellent job. I examined several databases, including some commercial ones, and for everything but speed PostgreSQL measured up nicely. And speed wasn't THAT bad, certainly quite acceptable for my purposes (and definitely a lot faster than it used to be!). -- Eric Lee Green eric@linux-hw.com http://www.linux-hw.com/~eric "Linux represents a best-of-breed UNIX, that is trusted in mission critical applications..." -- internal Microsoft memo

Just curious; I am using the same layout and RPM setup that the Red Hat 6.3 package had, but I had to make a fair number of changes to their setup to make 6.4 work. I think I probably ended up changing about 1/3rd of the "action" portions of their .spec file, and the patch file I used to make it install and link cleanly was generated from scratch. I am not doing this for Red Hat Software, I am doing it because I need to deploy 6.4 and doing it via RPM is the easiest way to deploy on Red Hat. And perhaps more importantly, I'm doing it because it's there :-). > I've been thinking about trying to help with RPM support but would be > happy that someone else is looking after it. Well, if you have some suggestions I'm certainly not loathe to ignore them! Right now, the only suggestion I can think of that I'd like to implement would be to somehow figure out how to compile the Python module at the same time that I compile the rest of it, but I'm not sure that Python is capable yet of doing that Perl trick of compiling a module against the Perl .so link library without having the source code around. I'll have to check with the Python gurus on that one. > Actually, we should also test with RH5.2 to make sure the date/time > problem is still present, since it may have been due to a problem in > glibc2 which has since been fixed. I'm only running RH4.2 and RH5.1 so > can't directly test that myself... Well, RH5.2 is still using glibc 2.0.7, albeit patched up about 10 more times since RH 5.1 :-). But sure, if you have a test case to run, drop it in the mail to me and I'll be happy to run it. One thought: Do you have a TZ environment variable set on your RH5.1? I don't remember whether glibc needs one or not (I know there were other programs sensitive to the TZ environment variable under RH5.1, like BRU, but it is 12:30am here on the east coast and my mind is not as clear as it should be :-). -- Eric Lee Green eric@linux-hw.com http://www.linux-hw.com/~eric "Linux represents a best-of-breed UNIX, that is trusted in mission critical applications..." -- internal Microsoft memo
