Results for using-temporary-files

Sorts large files using merge sort on temporary files on the hard drive. Also known as an external sort.

This gem creates dump file in temporary directory(if present otherwise create temporary directory) using construct method by passing username,database_name & host as parameter!

scbi_blast is a ruby gem to handle blast+ executions using pipes when possible to read data without the need of temporary files, it has been developed at [SCBI](http://www.scbi.uma.es) by Almudena Bocinos & Dario Guerrero.

Very useful for configuration files, SymbolMatrix is a hash-like multidimentional Symbol-only class with ability to discover and load YAML data

Parses profile settings and secrets from AWS CLI configuration files, including temporary credentials cached by the CLI when using roles.

Miscellaneous methods that may or may not be useful. sh:: Safely pass untrusted parameters to sh scripts. fork_and_check:: Run a block in a forked process and raise an exception if the process returns a non-zero value. do_and_exit, do_and_exit!:: Run a block. If the block does not run exit!, a successful exec or equivalent, run exit(1) or exit!(1) ourselves. Useful to make sure a forked block either runs a successful exec or dies. Any exceptions from the block are printed to standard error. overwrite:: Safely replace a file. Writes to a temporary file and then moves it over the old file. tempname_for:: Generates an unique temporary path based on a filename. The generated filename resides in the same directory as the original one. try_n_times:: Retries a block of code until it succeeds or a maximum number of attempts (default 10) is exceeded. Exception#to_formatted_string:: Returns a string that looks like how Ruby would dump an uncaught exception. IO#best_datasync:: Tries fdatasync, falling back to fsync, falling back to flush.

Random#exp:: Return a random integer 0 ≤ n < 2^argument (using SecureRandom). Random#float:: Return a random float 0.0 ≤ n < argument (using SecureRandom). Random#int:: Return a random integer 0 ≤ n < argument (using SecureRandom). Password:: A small wrapper for String#crypt that does secure salt generation and easy password verification.

Taski is a Ruby-based task runner currently under development. It allows you to define small, composable tasks along with the outputs they depend on. Taski statically resolves dependencies and executes tasks in the correct topological order, from the most dependent tasks first. It also supports reverse execution, useful for cleaning up temporary files after a build. **Note:** Taski does not yet support circular dependencies and may change as development progresses.

== DESCRIPTION: The RightScale AWS gems have been designed to provide a robust, fast, and secure interface to Amazon EC2, EBS, S3, SQS, SDB, and CloudFront. These gems have been used in production by RightScale since late 2006 and are being maintained to track enhancements made by Amazon. The RightScale AWS gems comprise: - RightAws::Ec2 -- interface to Amazon EC2 (Elastic Compute Cloud) and the associated EBS (Elastic Block Store) - RightAws::S3 and RightAws::S3Interface -- interface to Amazon S3 (Simple Storage Service) - RightAws::Sqs and RightAws::SqsInterface -- interface to first-generation Amazon SQS (Simple Queue Service) (API version 2007-05-01) - RightAws::SqsGen2 and RightAws::SqsGen2Interface -- interface to second-generation Amazon SQS (Simple Queue Service) (API version 2008-01-01) - RightAws::SdbInterface and RightAws::ActiveSdb -- interface to Amazon SDB (SimpleDB) - RightAws::AcfInterface -- interface to Amazon CloudFront, a content distribution service == FEATURES: - Full programmmatic access to EC2, EBS, S3, SQS, SDB, and CloudFront. - Complete error handling: all operations check for errors and report complete error information by raising an AwsError. - Persistent HTTP connections with robust network-level retry layer using RightHttpConnection). This includes socket timeouts and retries. - Robust HTTP-level retry layer. Certain (user-adjustable) HTTP errors returned by Amazon's services are classified as temporary errors. These errors are automaticallly retried using exponentially increasing intervals. The number of retries is user-configurable. - Fast REXML-based parsing of responses (as fast as a pure Ruby solution allows). - Uses libxml (if available) for faster response parsing. - Support for large S3 list operations. Buckets and key subfolders containing many (> 1000) keys are listed in entirety. Operations based on list (like bucket clear) work on arbitrary numbers of keys. - Support for streaming GETs from S3, and streaming PUTs to S3 if the data source is a file. - Support for single-threaded usage, multithreaded usage, as well as usage with multiple AWS accounts. - Support for both first- and second-generation SQS (API versions 2007-05-01 and 2008-01-01). These versions of SQS are not compatible. - Support for signature versions 0 and 1 on SQS, SDB, and EC2. - Interoperability with any cloud running Eucalyptus (http://eucalyptus.cs.ucsb.edu) - Test suite (requires AWS account to do "live" testing).
