Packages compiled with debug info

Hi,
How do we check if a package has been compiled with DEBUG information or not?
The package could have been compiled like this:
ALTER PACKAGE pk1 COMPILE DEBUG
Is there any table that I can check?
Thanks in advance.

Compiling with debug info

Hi!
I get a question about PL/SQl, How can I compile a Block PL/SQL with debug information, in SQL*Plus?
Thanks in Advance
- Pablo

From the symptoms you describe, it is possible that the shared library contains a bug, but it is more likely that the problem is in your code, passing bad data to the shared library.
The problem might be a compiler bug, but I think an error in your code is more likely.
For example, your code as written might have undefined behavior that works by accident when compiling without optimizing, but fails when the compiler improves the runtime code.
Some examples:
1. A classic MT programming error is failing to declare a variable volatile when it is shared by more than one thread. In each thread, the compiler assumes it can remember the value of the variable and not reload it between references.
2. "x = ++x + b;" Modifying a variable twice in an expression withtout sequence points has undefined behavior -- compiler optimization can affect the result.
3." foo(x, x+=3);" the order of evaluation of function arguments is unspecified, so the actual values passed to foo could depend on optimization.
With C++ 5.5, you get some warnings from system headers that you can't do anything about, which I suspect is why you have disabled some warnings. Unfortunately, you might be disabling warnings that you need to see. That is, some of the disabled warnings could point to invalid code that results in the program crash.
I suggest using w instead of w2 (to avoid uninteresting warnings), and fix your code to eliminate the warnings you get.
In the current compiler, C++ 5.7 in Sun Studio 10, we have made some adjustments to warnings to make w and w2 more useful. You should consider upgrading.You can get a 60-day free trial version here:

Also get the current patches for it here:

Looking for JDK binary compiled with debug info

For some reason JTree.startEditingAtPath() is not doing what I expect, and I'd like to step through the JDK code to see what's going on. Back with Java 5 there were debug builds of the JDK that would let me do this. I've been searching, but cannot find the equivalent for Java 6. Are there still debug binaries out there I can grab (and not have to compile the JDK myself)?

JDK is open source. Just get the source and step through it in your debugger.

Copied objects are compiled with debug True

I had an issue with copied packages/triggers/procedures that when they were copied showed up as compiled with debug status.
My sql developer client has a default setting of compilng PL/SQL code with optimization level = 0 , while our database has a default = 2.
When modifying this level and setting it to 0, the debug flag is turned on, although not specified in the sql developer client)
preferences -> database -> PL/SQL -> Optimization Level = 2
select * from v$parameter where name like 'plsql%' returns
888         plsql_debug      1             FALSE    FALSE
889         plsql_optimize_level     3             2             2 after setting the level to 0 the same query returns:
888         plsql_debug      1             TRUE     TRUE
889         plsql_optimize_level     3             0             0this compile with debug behavior is shown on oracle 10 and 11 databases.

I also have sqldeveloper version 3.2.20.09 and look up the value for optimizer in the preferences menu via preferences -> database -> PL/SQL (just as in my first message)
BTW I can still reproduce this issue (and 15 other dbas and developers at where I work) on both oracle 10 and 11.

BTW We've been using sqldeveloper here since version 2.x. We found a workaround by setting the value for Optimization Level to 2, although you might not reproduce the issue, I suggest to keep it for others, although it seems not many others experience this issue.

Release with debug info

In general, is it proper to release an official distribution with debug info, i.e., compile with -g option? is there a standard on this?
Thank you
J.L.

From my point of view from having worked in a department where we often got 3rd party code...
This is a customer service issue. If you leave the debug info in, then it will be easier for us (the customer) to understand what's going on when something breaks, and it will be easier for you to fix it.
You shouldn't remove the debug info unless you're 100% confident that the code is flawless (and you should never be so confident).
Similarly, you shouldn't obfuscate code unless the documentation is 100% complete. Some vendors are paranoid about their code being stolen, but most people decompile as an aid to understanding what they've purchased, not to steal it. Obfuscation reduces the usability of the product, and creates a hostile vendor/customer relationship.
Well, I've digressed a bit. The point is that unless there's a very strong reason otherwise, the customer service aspect trumps it and you should leave the debug info in.

How to determine if class was compiled with debugging information?

How may I determine if class was compiled with debugging information? Aside from actually executing the class in a debugger.

As known, when compiling "javac -g ..." the class
files contain debugging information.
my Naive question is WHAT is this information?
could you please add any links to articles about this
debugging information?http://java.sun.com/docs/books/vmspec/2nd-edition/html/ClassFile.doc.html#22856

Compiling with debug option

How to give user Compiling with debug option, i have try to by giving grant debug any procedure and debug connect session but it failed.
Any ideas?
Edited by: rootsman on Jul 15, 2010 12:00 AM

Post the error screenshot..
eg:
grant DEBUG CONNECT SESSION to username;
grant DEBUG ANY PROCEDURE to username;
Check the below explanation:
DEBUGGING:
DEBUG CONNECT SESSION
Connect the current session to a debugger that uses the Java Debug Wire Protocol (JDWP).
DEBUG ANY PROCEDURE
Debug all PL/SQL and Java code in any database object; displayinformation on all SQL statements executed by the application
Note: Granting this privilege is equivalent to granting the DEBUG object privilege on all applicable objects in the database.

PHP5 package compiled with LDAP support?

When I check phpinfo() it appears the PHP5 package was compiled with LDAP support but for some reason when I try a ldap_connect function in php it errors with 'Fatal error: Call to undefined function ldap_connect() in ...'
Anybody have any idea what the problem is?
Thanks,
Craig

I'm not sure about the php.ini thing, I've combed through it looking for idea's as well, but the only ldap string in the whole file is this 'extension=php_ldap.dll' and that doesn't apply to Arch.
Also at http://www.php.net/ldap it talks about requirements etc and I'm almost thinking that the php5 package is not compiled with ldap even though when I do a phpinfo() it does show '--with-ldap' in the compile settings.

Ack! Please ignore my earlier posting. I did not play close enough attention to details in your post. I apologize for the confusion. Let me start over:
The Studio Express release you have contains a newer version of the C++ runtime library libCstd.so.1 than is available yet in Solaris patches. We bump the internal version number when we add new interfaces. The internal version number of the Studio Express library is SUNW_1.3.2. The version of the latest release Solaris patch is SUNW_1.3.1.
Some new string class operator functions are in version SUNW_1.3.2. I think these are also defined as inline functions in the compiler headers. When you compile with -g, inlining is disabled, and you create a dependency on library version SUNW_1.3.2. (Compiling with -g0 allows function inlining, and might resolve your problem, but read on.)
We have not released a libCstd.so.1 with internal version SUNW_1.4.2, so I don't understand how that version number could appear in an error message. Did you really see that version, or is it a transcription error? For now, let's assume it is a transcription error.
When you compile and link with CC, the program gets a runpath pointing into the compiler installation area. At program run time, the loader looks for libraries in directories listed in the runpath, with /lib and /usr/lib as last resort. The "ldd" command reports what the runtime loader will do regarding dependent libraries.
If the compiler is installed in /opt, a 32-bit program gets a runpath that includes /opt/SUNWspro/lib. In that directory in Sun Studio Express is a symbolic link that points to ../prod/usr/lib/libCstd.so.1, the library with version SUNW_1.3.2.
If you try this:
% /opt/SUNWspro/bin/CC hello.cc
% ldd a.out
you should see, among other things,
libCrun.so.1 => /opt/SUNWspro/lib/libCstd.so.1
(Depending on the OS version, you might see
libCrun.so.1 => /opt/SUNWspro/prod/usr/lib/libCstd.so.1 instead.)
But if ldd can't resolve the library, you probably have a corrupted Sun Studio Express installation. In that case, uninstall it, and reinstall from a fresh download.
If you run the program on a different computer where Sun Studio Express is not installed, the loader won't be able to find the right library version, and you will get "not found" results. I addressed this issue in another thread:

Problem with debug info...

Hi
CC -V
CC: Sun C++ 5.9 Linux_i386 Build27_2 2006/08/02
CC -g -c test.cpp
>> Assertion: DBGGEN ERROR: FILE="../src/dbg_dwarf2.c", LINE=%7605, DW_DLE_DEBUGINFO_ERROR [DBG_GEN 5.1.18] (../lnk/dbg_dbggen.cc, line 4336)
while processing test.cpp at line 0.I can not paste test.cpp here though, it's quite huge since I created it with CC -E, but anyway, perhaps someone at sun is interested ?

This looks like bugid 6456470. It's fixed in our development
branch, but the fix won't be available until Express 3 which
isn't for a month or two. The problem is related to the way
symbols and types reference other symbols and types. You
can work around it by not using -g for those source files where
it happens. Not a very good workaround, I know. Of course,
that's why we have express releases. To find problems like
this as early as possible. ;-)

Compiling with debug and runtime performance degradation

Just a quick question: Does including debug information in class files degrade runtime performance in any way?
Thanks!

Quick answer: it depends on what your application does.
Mostly, it shouldn't matter but you should always profile and time your
application to find the truth.

Debug info unavailable for web services

I've run into an interesting problem. I'm trying to remote debug a web service
I've deployed on wls 7. I can connect to the server, place breakpoints, and step
through the code, but there isn't any information available (objects, stack, etc).
It just says debug info unavailable. Thing is, there is another application deployed
in which I can see all the debug info. Yes, they're both compiled with debug info
turned on.
I originally thought that a difference in deployment might be an issue, since
one is deployed as a directory, and the other as an ear file, but deploying them
both as a directory didn't seem to help. Does anyone have any idea?
My debugger is the one included in intellij idea...

Can I (using the instructions found in the whitepaper entitled, Setting up SSL of Web Services in LabVIEW 2009) setup a LabVIEW server on the same PC so that I can test my client. I just want to debug my handshaking code, and verify that I can setup a secure link. I'm not sure how I'll know just yet, but I'm wondering (until I get the 3rd party server) if I can do it all locally to accelarate testing.

Cannot compile code with debug symbols

I have a source code file that will not compile with debug symbols. I get an assertion failed in file ../src/regman/regman_local.cc at line 5224. The compile command and output are below.
/opt/SUNWspro/bin/cc -g -xarch=v9b -xopenmp=noopt -xc99=all -c -o output/spirecon.o spirecon.c
cg: assertion failed in file ../src/regman/regman_local.cc at line 5224
cg: Out of range
cg: 1 errors
cc: cg failed for spirecon.c
However without the debug options and using the default -fast switch, i.e.
/opt/SUNWspro/bin/cc -fast -xarch=v9b -xopenmp=noopt -xc99=all -c -o output/spirecon.o spirecon.c
it compiles without any problems.
I was hoping someone might have a suggestion as to how what might cause this type of error.

I have been told this is bugid: 4420630
It only happens when you try to use the optimizing
backend code generator without any optimization.
(That's what -xopenmp=noopt does)
If you add an -xO1 flag the assertion should go away, but you
will also lose some (but not all) of your debuggability.

Isn't PKGBUILD just a script? It calls what you make it calls by adding commands...
