storable

something interesting. 1: The results returned by the page expose the target using Perl and Storable 2.7. After Google search, I know that Storable is a Perl module used for data serialization. Check the Storable official documentation. We can see a large security prompt: Some features of Storable can lead to secur

IDPrivate int recordId; // the ID of the corresponding recordPrivate String key; // The Key of the access record} Search by index, and perform the following three steps: 1. Search for the corresponding IndexEntry In the RecordStore named "index" based on the String.2. Retrieve the IndexEntry and obtain the ID of the record.3. obtain another RecordStore Record Based on the ID number, and then you can read, update, and delete the record. As shown in: Because the IndexEntry stores very little da

DNS servers refuse to respond to requests from non-local operators in the region, so we have to distribute the monitoring sites to different places. In fact, it is enough to use the nagios distributed method to do this. However, if you want to do an instant trigger emergency task, even if you click execute immediately on the nagios page, it will take a while to return all the results. Therefore, I chose to write a distributed asynchronous system. The central controller script is as follows: #!

, changed! Your/perl/install/DIR/bin/Perl.Step 4: Check whether the bugzilla module is missing. Sadly, I was prompted that the old storable module could not be found during execution. I downloaded the latest one from www.cpan.org. So I had to hack checksetup. Pl to see what was going on. It turns out that the version numbers required by the storable and dynloader modules do not match. It requires version 2.

Serialize () and unserialize () are explained in the PHP manual as: Serialize-generates a storable representation of a value, producing a representation of the value that can be stored. Unserialize-creates a PHP value from a stored representation to create a PHP value from the stored representation. Serialize () returns a string that contains a byte stream representing value that can be stored anywhere. This facilitates the storage or delivery of

an abstract basic subclass for easy implementation of portable server applications, which provides a way to implement a Daemon common task: start, log on, connect to the client, authenticate, set environment variables for security, and enter the working status. 　　 Storable-0.6.11 makes data storage more continuous and stable. You can store any data structure to the disk in a recursive way. you can also retrieve data from the storage file and recreate

The client serialization object of Perl memcached adopts the nfreeze method of the storable module, which calls the C extended do_store method. The deserialization uses the thaw method of the storable module, this method is the do_retrieve method of the c extension called. In PHP, The serialize and unserialize operations are performed. Results that cannot be normally read. Perl stores references to an arr

1 wants to store the data "Barbaz" with Key "Foo". Client 1 first refers to the node list (A, B, C) and calculates the hash value of key "foo", assuming memcached B is selected.　　Then, Client 1 directly connect to memcached B, and the data "Barbaz" is stored through key "foo". Client 2 uses the same clients library (which means phase one is the same as the hashing algorithm) and also has the same memcached list (A, B, C).So, after the same hash calculation (phase one), Client 2 calculates the k

Client 2 uses the same clients library (which means phase one is the same as the hashing algorithm) and also has the same memcached list (A, B, C).So, after the same hash calculation (phase one), Client 2 calculates the key "foo" on memcached B, and then it requests memcached B directly to get the data "Barbaz".Various clients have differ

then be saved after serializing complex Perl data through the Storable module, so hashes, arrays, objects, and so on can be saved directly to the memcached.
