Results for alloc-checked

Collections that don't panic on alloc failures

RSpec helpers for checking memory allocations.

# CheckTCPMemory This is a simple Nagios/Sensu check that checks that the current TCP memory usage is below the maximum allowed in the Linux kernel. This will find leaking TCP sockets. ## Installation Add this line to your application's Gemfile: ```ruby gem 'check_tcp_memory' ``` And then execute: $ bundle Or install it yourself as: $ gem install check_tcp_memory ## Usage ``` $ check_tcp_memory -h Usage: check_tcp_memory -w <warn percent> -c <critical percent> -w, --warn-percent PERCENT Warning when percentage of total TCP memory is over this threashold. Default: 50% -c, --crit-percent PERCENT Critical when percentage of total TCP memory is over this threashold. Default: 60% -h, --help Show this message --version Show version ``` ## Development After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment. To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org). ## Contributing Bug reports and pull requests are welcome on GitHub at https://github.com/Altiscale/check_tcp_memory. This project is intended to be a safe, welcoming space for collaboration, and contributors are expected to adhere to the [Contributor Covenant](contributor-covenant.org) code of conduct.

Hakto Safe SDBM Wrapper ======================= ## Introduction Hakto Safe SDBM Wrapper is a safe wrapper of SDBM library. Hakto has compatibility of instance method's interface that is in SDBM class. Hakto enables to tighten up a code that uses SDBM library like following codes. **before** class Klass def initialize(db_path) @db_path = db_path end def method1 SDBM.open(@db_path) do |dbm| dbm["hoge"] = "HOGE" end end def method2 SDBM.open(@db_path) do |dbm| dbm["hoge"] end end : end **after** class Klass def initialize(db_path) @sdb = Hakto::SafeSDBM.new(db_path) end def method1 sdb["hoge"] = "HOGE" end def method2 sdb["hoge"] end : end ## Operation Environment We checked good operation within following environment. - Linux（openSUSE 12.2）・Mac OS X 10.8.2 - Ruby 1.9.3 ## Architectonics - **bin** - **doc** :: Rdoc documents. - **lib** - **hakto** - **safe_sdbm.rb** :: Class of SafeSDBM - **LICENSE** - **Rakefile** :: Rakefile that is used to generate gem file - **README.md** - **README_jp.md** - **test** :: Unit tests - **tb_safe_sdbm.rb** :: Unit test for SafeSDBM ## Install Download hakto-x.y.z.gem, then execute following command to install Hakto. `$ sudo gem install hakto-x.y.z.gem` On the other hand, you can install from RubyGems.org to use following command. `$ sudo gem install hakto` Also you can install Hakto without gem. Allocate the safe_sdbm.rb where is ruby interpreter can load Hakto. ## Sample code See tb_safe_sdbm.rb file. It is an unit test code, and it doubles with sample code. ## API document See following website: [http://quellencode.org/hakto-doc/](http://quellencode.org/hakto-doc/ "") ## About Author Moza USANE [http://blog.quellencode.org/](http://blog.quellencode.org/ "") mozamimy@quellencode.org
