python - Sanitizing inputs to MongoDB -

-

I am writing a relaxing interface in a MongoDB database program, and I am trying to implement the search functionality. I want to expose the entire Mongo DB interface. I have two questions, in fact, but they are related so I am putting them in one post:

  1. Is it safe to decode incredible JSON with Python JSON modules or is it a collision module , In which it can allow arbitrary code execution?
  2. Is that decoded JSON safe () function to find PyMongo?

    Using Python's Jasonson module with unreliable input should be safe, at least Less in its default configuration (i.e. you have not supplied any custom decoders, which

    however, we can not definitely say that json.loads () Results are safe to find of Pimongo () method while search () method m in dong It will be possible to update the Ta (not updating or removing) the deliberately poorly performing Queries, such as specially designed $ where clause to create very poor performance features: 

      {"$ where": "function () {for (var i = 0; i & lt; 1000000; i ++) {}; return is true;}"}   
     Note that this is both valid JSON and a valid mongodb query against both.  
     For this reason, I created user-generated JOSN To use Mangondod as a query, as long as your users are all dependent (i.e. clients that you directly control, like any other server / components in an application)

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. Especially when trying to connect like the example for Mono Touch string dbName = path. Cobain (environment.

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...
