New page:
=3D=3D Setting Up Environment =3D=3D

Open !PowerShell as administrator (=E2=80=9Crun as administrator=E2=80=9D o=
n right-click), and peform the steps below:
 =

  * Set the execution policy as remotesigned in order to install chocolatey:
    * `set-executionpolicy remotesigned`
  * Install chocolatey package manager
    * Install instructions available [[https://chocolatey.org/|here]]
  * Install the following packages with =E2=80=9Cchocolatey install <packag=
eName>=E2=80=9D
    * Mandatory packages (running, compiling and installing)
      * jdk7 and/or jdk8 (depending on C* version to develop)
      * ant
      * git
      * python2
      * easy.install
      * pip
    * Optional packages (productivity)
      * gnuwin
      * poshgit

=3D=3D Running cassandra-dtests =3D=3D

  * Set $CASSANDRA_DIR environment variable (the environment variable will =
only be exported during next terminal session)
    * `[Environment]::SetEnvironmentVariable("CASSANDRA_DIR", "c:\Users\<us=
ername>\<cassandra_dir>", "User")`
  * Download and install Microsoft Visual C++ Compiler for Python 2.7
    * Available on [[https://www.microsoft.com/en-us/download/confirmation.=
aspx?id=3D44266|this link]]
  * Instal necessary python modules
    * `pip install blist git+https://github.com/datastax/python-driver.git@=
cassandra-test git+https://github.com/pcmanus/ccm.git cql decorator enum34 =
flaky futures nose nose-test-select pycassa six thrift psutil`
    * Check https://github.com/riptano/cassandra-dtest/blob/master/requirem=
ents.txt for new requirements

=3D=3D Running CCM =3D=3D

   * You need to set the execution policy to unrestricted to run CCM on !Po=
werShell as administrator:
    * `set-executionpolicy unrestricted`
   * Add .PY extension to environment variable $PATHEXT, to allow ccm to be=
 executed from any location (run on !PowerShell as administrator):
    * `[Environment]::SetEnvironmentVariable("PATHEXT", "$env:PATHEXT;.PY",=
 "MACHINE")`
   * Create a symbolinc link (as administrator) to make chocolatey ant work=
 with ccm, since ccm expects an ant.bat executable, while chocolatey create=
s and ant.exe file:
    * `cmd /c mklink C:\ProgramData\chocolatey\bin\ant.bat C:\ProgramData\c=
hocolatey\bin\ant.exe`

=3D=3D Script for switching JDKs =3D=3D

In a mixed JDK7/JDK8 the following PowerShell functions might be useful for=
 switching jdks (place them on `$ENV:HOME\Documents\WindowsPowerShell\profi=
le.ps1`):

{{{
function updateJavaHome($newHome)
{
    $env:JAVA_HOME=3D$newHome
    [Environment]::SetEnvironmentVariable("JAVA_HOME", $env:JAVA_HOME, "Mac=
hine")
}

function updateRegistry($newVersion)
{
    Set-ItemProperty -Path 'Registry::HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\=
Java Runtime Environment\' CurrentVersion $newVersion
}

function updatePath
{
    $PathWithoutJava=3D(($Env:Path).Split(";") | where {$_ -notmatch 'java'=
}) -join ";"
    $NewPath=3D"$env:JAVA_HOME\bin;$pathWithoutJava"
    $Env:Path=3D$NewPath
    [Environment]::SetEnvironmentVariable("PATH",$NewPath,"Machine");
}

function java8
{
    updateJavaHome("C:\Program Files\Java\jdk1.8.0_51")
    updateRegistry("1.8")
    updatePath
}

function java7
{
    updateJavaHome("C:\Program Files\Java\jdk1.7.0_76")
    updateRegistry("1.7")
    updatePath
}
}}}
