perl - How to filter a lot of data with IPC::Open2? -

-

My job is to filter some data with Perl scripts with external usability (ADR2 line). The size of the data is quite large. I need to print many data to the program stdin and read a lot of data back (from the stdout program in my script).

Now I do it with IPC :: Open2 , but I do not like to read and write. Is it legal? open2 will buffer data of any size in the pipe?

My code: 

  My $ cmd = "addr2line -e $ prog_name"; Use IPC :: OpenOffice; Local (* Reader, * Writer); My $ pid = open2 (* * Reader, * author, $ CMD); (@requests) {# This array is large, more than 100 print author "$ _ \ n" of thousands of entries; } Close authors; (@requests) {$ function_name = & lt; Reader & gt; $ Filesource = & lt; Reader & gt; # ... store ..} close reader; Waitpid ($ PID, 0);    
 
 
 Yes, you will write your program in the barrier of buffer capability. Your input buffer ( Reader ) will fill and block the execution of your external program.  
 The reading and writing mix will help, because you are about to empty the input buffer about the external program. It is the rate of filling it.  
 Another thing that is using files for interprocess communication instead of pipes or sockets (as it does  IPC :: Open2 ) helps. Then you will only be limited to the amount of free disk space. You can do it yourself, though by default use the files for the IPC.  
  Use Forks :: Super 'Open2'; ... my ($ $ reader, $ author, $ pid) = open2 (@command); {$ $ Author $ $ _ \ n "} $ $ Author for $requests; (@requests) {... read ...} For $ $ Reader; Wait $ pid, 0;

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...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

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...
