ruby on rails - rake task memory leak -

-

Do I have the work of a long-running rack that tilts my system memory over time? What is the fastest way to track my problem and reach out to it?

I am using Ubuntu on Rails 2.3.5, Ruby 1.8.7, SliceHost and MyScl 5.

I have a rail app that works fine I have a night job that runs all night and works a lot (some external calls, Twitter, Google etc), and many DB calls active Using the record, over time this work increases memory size up to 4 gig. I do not know why the rack is not releasing the memory of the memory.

I started looking for a black box, but it Setup to look complicated Yes and has not been updated for more than a year. I am not able to take it for work locally so that I try to produce.

Thanks Joel

Before throwing two ideas, you are looping as part of this job, make sure that you refer to those items You are not catching up because you do not need them, because they should be collected from them. If you have done, remove them from your array, or whatever else, enter a periodic GC.start in your loop to see if this is not just around GC-ING .

The second idea is that Ruby does not have GC symbols, so if your API client can accumulate values ​​as a symbol of you, ends with a large and rising symbol, which ever Will not be used from Symbols are small, but small things can still be added

And, of course, do not load as much items as you need, use #find_each to load AR objects in batch if you Many of them have to iterate over.

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...
