linux - Can io scheduling priority be set on a filehandle basis? -

-

What folds can open in Linux, do they have an io scheduling preference? IONOS allows you to fully determine the IO priority for the processes. Is it possible for a process, for example, unnecessary priority on a file handle but general priority on the other? Or, to implement something like this, do I have to change the priority of 'io scheduling of processes because every file is read by hand?

I do not think that's straight, right.

Unix V6 Kernel (C.1978) Based on the characteristics of some devices, the awakening priority for different values ​​will give priority, depending on the length of the delay. If that functionality has been moved to Linux, then it may be used for your purposes.

Otherwise, you have to modify the kernel for your purposes. May increase the ioctl () to set the file to a new area with scheduling bias.

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...
