Hi Stefan,
I am trying to restore "monetdb5/extras/crackers" to the MonetDB-11.15.3 release. I have done the following steps:
1. copied monetdb5/extras/crackers over
2. copied ./monetdb5/optimizer/opt_wrapper.c
3. changed monetdb5/extras/Makefile.ag to add the crackers sub-directory
4. changed monetdb5/extras/crackers_sideways.mx to eliminate references to lview
5. added the "cracker_pipe" in opt_pipes.c
6. changed common/options/monet_options.c to use the "cracker_pipe"
However, the "cracker_pipe" optimizer could not be compiled at the following line:
#0 getAddress (out=0x8bff950, filename=0x0, modnme=0x8b9ff90 "optimizer", fcnname=0xb77a697f "OPTselcrack", silent=1) at mal_linker.c:119 #1 0xb776e726 in compileOptimizer (cntxt=0x8091b58, name=0x83a8320 "cracker_pipe") at opt_pipes.c:555 #2 0xb776e98d in addOptimizerPipe (cntxt=0x8091b58, mb=0x8b1c578, name=0x83a8320 "cracker_pipe") at opt_pipes.c:598 #3 0xb63c3ecf in addOptimizers (c=0x8091b58, mb=0x8b1c578, pipe=0x83a8320 "cracker_pipe") at sql_optimizer.c:244 #4 0xb63c4104 in addQueryToCache (c=0x8091b58) at sql_optimizer.c:292 #5 0xb63c296c in backend_dumpproc (be=0x8e145b0, c=0x8091b58, cq=0x8b48b58, s=0x903f620) at sql_gencode.c:2433 #6 0xb639ee0a in SQLparser (c=0x8091b58) at sql_scenario.c:1709 #7 0xb7580e3a in runPhase (c=0x8091b58, phase=1) at mal_scenario.c:522 #8 0xb7580f98 in runScenarioBody (c=0x8091b58) at mal_scenario.c:557 #9 0xb7581169 in runScenario (c=0x8091b58) at mal_scenario.c:586 #10 0xb75820ef in MSserveClient (dummy=0x8091b58) at mal_session.c:431 #11 0xb70e013a in wrapper_routine (data=0xb6784f5c) at gdk_system.c:559 #12 0xb6b3bb05 in start_thread () from /lib/libpthread.so.0 #13 0xb6a9cd5e in clone () from /lib/libc.so.6
The function getAddress could not find OPTselcrack(). I did a symbol dump of the built lib_crackers.so and got:
chiku@linux-c2ni:/usr/local/lib> nm ./monetdb5/lib_crackers.so | grep OPTselcrack 005da67d T OPTselcrack 005d9c94 t OPTselcrackImplementation
I also examined the outputs from "make; make install" from MonetDB-11.9.7 and the above built process. But, there was not any visible difference.
Could you point out what I missed?
Thanks in advance.
Chi

It's a shared library that will only be loaded once required at run time. Just say yes when gab asks you if the breakpoint should only be set once the library/code is loaded.

Hi Babis,
Thanks a lot for your help!
I am able to get the foo directory compiled and built lib_foo.la. But, when I attatch GDB to the mserver5 process and try to set a breakpoint in foo.test(), I got an error saying foo.test() is not loaded. Have I missed anything?

Hi,
you have to edit monetdb5/extras/Makefile.ag appending to variable SUBDIRS the name of the directory you want to add. For example, if you want to add directory "foo", given that the value of SUBDIRS was
HAVE_RAPTOR?rdf HAVE_SPHINXCLIENT?sphinx HAVE_JAQL?jaql mal_optimizer_template
the new value for SUBDIRS should be
HAVE_RAPTOR?rdf HAVE_SPHINXCLIENT?sphinx HAVE_JAQL?jaql mal_optimizer_template foo
Of course, this way you should run de-bootstrap and bootstrap again. Notice, that you have to specify also another Makefile.ag in monetdb5/extras/foo for taking care of the compilation of your code.
However, I don't see any connection of your question to the message you replied to.

Hi,
I would like to add a new sub-directory to /monetdb5/extras/ so that:
1. the configure process generates Makefiles for it and
2. it gets built when "make" is invoke in the top source directory.
Thanks in advance.

I have a question about remote.exec(). Let's say I have a user function, s1_1 that takes a BAT as a parameter and returns a BAT. Its signature might be:
function user.s1_1(in:bat[:oid,:int]):bat[:oid,:int];
How can I call s1_1 using remote.exec to pass in a BAT and to retrieve the result? I want to do something like
X_2 := remote.exec(conn, "user", "s1_1", X_1);
where X_1 and X_2 are both :bat[:oid,:int]. But that doesn't seem to work.
Thanks,
Steve Morgan
