linux - What is the recommended way to perform source-level debugging of system library calls? -

-

I need to debug some calls in the system library, to understand how the call is different, and why a Or the other will fail.

Compromised system libraries and separate debug symbol files for Linux Distros, for example, /lib/libc-2.8. Therefore, symbols have been stripped, leaving information behind a section called .gnu_debuglink that contains information to find a different debug file. Separate debug files are installed through the debug package, and contain the symbolic information required by GDB. It is well described and

After installing the debug package and sources, I was hoping that GDB symbols and sources would be available and I would be able to see the listing and take steps in the calls. Instead, GDB tells me "no line number to go for xyz"

I've verified that the debug-file-location is correct, and the directory is set to source directories.

Is it possible to do what I want to do? Am I going to go wrong about this? Is there an easier way?

Did you have the debug-file-directory parameter in GDB? According to the documents that you have provided, you should do what you want:

Set the set debug-file-directory directory which GDB provides separate debugging notification files You can set up multiple directory components in a directory by searching for a directory separator.

show debug-file-directory Show GDB searches for separate debugging information files in directories.

For example in my Fedora distribution, the directory is / usr / lib / debug .

You can also define it by compiling it over time Configure - Together-debug-dir = / usr / lib / debug ...

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
