powershell_script "DynamicCompressionLevel" do
    code <<-EOB
        Set-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST'  -filter "system.webServer/httpCompression/ 'gzip']" -name "dynamicCompressionLevel" -value 4
    EOB
    not_if 'powershell -noninteractive -noprofile -command "exit [int32]((get-WebConfigurationProperty -pspath "MACHINE/WEBROOT/APPHOST"  -filter 'system.webServer/httpCompression/ "gzip"]' -name "dynamicCompressionLevel").value -eq 4)"'
end

 

I get the following:

[2014-02-25T16:01:22-05:00] FATAL: SyntaxError: c:/chef/cache/cookbooks/poshMover/recipes/exetest.r

changed code to the following

powershell_script "DynamicCompressionLevel" do
    code <<-EOB
        Set-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST'  -filter "system.webServer/httpCompression/ 'gzip']" -name "dynamicCompressionLevel" -value 4
    EOB
    not_if <<-EOH
        'powershell -noninteractive -noprofile -command "exit [int32]((get-WebConfigurationProperty -pspath "MACHINE/WEBROOT/APPHOST"  -filter "system.webServer/httpCompression/ 'gzip']"" -name "dynamicCompressionLevel").value -eq 4)"'
    EOH
end

Again it "Works" but the not_if appears to be not functioning (is, it doesnt skip the second time)

Kenneth, I think there is a quoting issue in the argument for –filter – I couldn’t execute that when I pasted your command into PowerShell. Using single quotes instead of double quotes did the trick, i.e.

 

[int32]((get-WebConfigurationProperty -pspath "MACHINE/WEBROOT/APPHOST"  -filter 'system.webServer/httpCompression/ "gzip"]' -name "dynamicCompressionLevel").value -eq 4)

 

worked on my system. In general, quoting is something to be mindful of when mixing languages in this way (i.e. Ruby and PowerShell). Using here documents can help, though it is less concise.

What am I doing wrong?

I expect the sode block to "not [run] if" the value of the setting is current '4'.

When I run this code

powershell_script "testDynamicCompressionLevel" do
    code <<-EOB
        Set-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST'  -filter "system.webServer/httpCompression/ 'gzip']" -name "dynamicCompressionLevel" -value 4
    EOB
    not_if 'powershell -noninteractive -noprofile -command "exit [int32]((get-WebConfigurationProperty -pspath "MACHINE/WEBROOT/APPHOST"  -filter "system.webServer/httpCompression/ "gzip"]" -name "dynamicCompressionLevel").value -eq 4)"'
end

on  machine 1 the powershell command in the not_if evaluated to false (because its set to 0) I run this command from the prompt on the machine locally.

upon chef-client i get the following lines:

[2014-02-25T13:23:16-05:00] INFO: powershell_script[testDynamicCompressionLevel] ran successfully

    - execute "powershell.exe" -NoLogo -NonInteractive -NoProfile -ExecutionPolicy RemoteSigned -InputFormat None -File
"C:/Users/kbarry-x/AppData/Local/Temp/chef-script20140225-2672-jjmxxc.ps1"

and not the setting is '4', so the test evaluates as true

but when I chef-client again i get the same results, instead of a "skipped due to not_if"
