I'm doing an online-judge application and I wish to run a ruby script (or a c++, java, etc program) from a controller, save the output in a variable and compare it to a test file I have in my database.
I'm stuck with running the program and checking the answer it sends to standard output. I've tried answer = load path, (being "path" a variable with the path of the script) but that returns "true" instead of the stdout content; and answer = `ruby path` but it doesn't recognize the path variable.
Thanks for your time in advance.
Try this: system("ruby #{path}"), but be careful not to pass any user-submitted information to the path variable (or at least sanitize it thoroughly), as this can pose extremely serious security risk.

I need to set variables in root scope in one job to be used in a different job. The first job has a Javascript job entry, with the statements:
parent_job.setVariable("customers_full_path", "C:\\customers22.csv", "r");
true;
But the compilation fails with:
Couldn't compile javascript:
org.mozilla.javascript.EvaluatorException: Can't find method
org.pentaho.di.job.Job.setVariable(string,string,string). (#2)
How to set a variable at root level in a Javascript job entry?
Sorry for the passive agressive but:
I don't know if you are new to Pentaho but, the most common mistake for new users, with previous knowledge of programming, is to be sort of 'addicted' to know methods, as such you are using JavaScript for a functionality that is built in the tool. Both Transformations(KTR) and JOBs(KJB) have a similar step, you can better manipulate this in a KTR.
JavaScript steps slow down the flow considerably, so try to stay away from those as much as possible.
EDIT:
Reading This article, seems the only thing you're doing wrong is the actual syntax of the command..
Correct usage :
parent_job.setVariable("Desired Value", [name_of_variable]);
The command you described has 3 parameters, when it should be 2. If you have more than 1 variable you need to set, use 3 times the command. Try it out see if it works.
I have alot of Bamboo variables defined due the fact that i have a system with alot of legacy and config at places where it does not belong. Getting rid of all this will take a bit longer on the roadmap so i need to find a way to auto replace all these values.
The number im talking about is that there are 8 customer config files with each about 100 variables. Indeed, there was a maniac who added all of those in Bamboo because as you might thought most of them are variable for each environment.
At this moment i want to automate the deployment process and all is going fine exact the fact that i need to replace 100 variables and i dont want to maintain it in my script itself all the time.
I am looking for a way to retrieve all the variables in an array so i can just iterate through all the keys and try to replace them at the config files.
echo "${bamboo.application.myvalue}" will replace the value as expected. The only problem is, how can i get all the keys under bamboo.*
I tried it with the following functions but all without success:
printenv
env
declare
All above without success. How can i retrieve a list of all those variables as inline script in Bamboo.
Thanks alot
I think it is not possible to change the value of the variables on the fly. Instead, you can use the "Inject Bamboo variables" task in order to be able to change the variable value.
This task reads a file to create the variables. So, all you have to do is to create this file with the values you need, and then use this variables.
E.g.: Creating a file from a powershell script:
$path = 'bambooVariaveis.properties'
$connectionstringX = 'connectionstring="Data Source=XXXX;"'
$Utf8NoBomEncoding = New-Object System.Text.UTF8Encoding($False)
[System.IO.File]::WriteAllLines($path, $connectionstringX, $Utf8NoBomEncoding)
E.g: Inject Bamboo Variables config
Using it (in a subsequent script task):
echo ${bamboo.inject.connectionstring}
I am trying to run a C# program to determine if a directory exists on multiple servers, so I need to run it as %system Variable%, rather than making a drive letter call, since not every server will have the same drive letter. This is what I have:
If My.Computer.FileSystem.DirectoryExists("D:\backup") Then
This code will work, as I define the drive
If My.Computer.FileSystem.DirectoryExists("%BCK_DRV%\backup") Then
This will not, I get my else error when running it. The %BCK_DRV% is defined in the environment variables, and I can navigate to the folder without issue using %BCK_DRV%\backup. Is there a special way to set and define a %drive% in C#?
Environment.GetEnvironmentVariable?
Code sample:
Dim backupDrive As String = Environment.GetEnvironmentVariable("BCK_DRV") & "\backup"
If My.Computer.FileSystem.DirectoryExists(backupDrive) Then
Try Environment.ExpandEnvironmentVariables():
string raw = #"%BCK_DRV%\backup" ;
string expanded = Environment.ExpandEnvironmentVariables( path_raw ) ;
Naturally, it's up to you to ensure that your process inherits the correct environment.
To expand "%BCK_DRV%\backup" to it's real value you need
Environment.ExpandEnvironmentVariables();
Example:
Environment.ExpandEnvironmentVariables("%winDir%\test")
will expand to "C:\Windows\test" (on my system).
I need to embed some resource in a pure compiled dll written in php using phalanger.
These are txt files tha I set in visual studio as "Embedded Resource".
My problem is that I cannot use the Assembly class to get the resource using GetManifestResourceStream.
I tried code like this:
use System\Reflection\Assembly
$asm = Assembly::GetExecutingAssembly(); //this gives me mscorlib instead of my dll
$str = $asm->GetManifestResourceStream("name");
My question is: how do I get access to embedded resources in phalanger?
Many thanks
I'm not sure, why Assembly::GetExecutingAssembly() returns an incorrect value. Anyway to workaround the $asm value, use following code:
$MyType = CLRTypeOf MyProgram;
$asm = $MyType->Assembly;
Then you can access embedded resources as you posted
$asm->GetManifestResourceStream("TextFile1.txt");
or you can include standard resource file (.resx) into your project, and use \System\Resources\ResourceManager
$this->manager = new \System\Resources\ResourceManager("",$asm);
$this->manager->GetObject("String1",null);
Just note, currently there can be just one .resx within Phalanger project
This question is old, but the part of the Phalanger code (Php.Core.Emit.AddResourceFile() method) responsible for this hasn't changed since this was asked. I faced the same problem and solved it in (almost) non-hacky way. You have to provide alternative name (/res:/path/to/filename,alternative-name) for this to work though.
$asm = clr_typeof('self')->Assembly;
$resourceStream = $asm->GetManifestResourceStream("filename");
$reader = new \System\Resources\ResourceReader($resourceStream);
$type = $data = null;
$reader->GetResourceData("alternative-name", $type, $data);
// and still there are 4 excess bytes
// representing the length of the resource
$data = \substr($data, 4);
$stream = new IO\MemoryStream($data);
// after this $stream is usable as you would expect
Straightforward GetManifestResourceStream() (as suggested by Jakub) does not work because Phalanger does not use System.Reflection.Emit.ModuleBuilder.DefineManifestResource() (like I think it should when supplied with unrecognized file format). It uses ModuleBuilder.DefineResource() which returns ResourceWriter instead, that only really suited for .resources files. And this is what dictates the requirement to use ResourceReader when you need to read your resource.
Note: This answer applies to Phalanger master branch at the time of writing and prior versions since circa 2011. Noted because it looks like a bug (especially the need to use both original and alternative names).
for some test I need to run a data driven test with a configuration that is generated (via reflection) in the ClassInitialize method (by using reflection). I tried out everything, but I just can not get the data source properly set up.
The test takes a list of classes in a csv file (one line per class) and then will test that the mappings to the database work out well (i.e. try to get one item from the database for every entity, which will throw an exception when the table structure does not match).
The testmethod is:
[DataSource(
"Microsoft.VisualStudio.TestTools.DataSource.CSV",
"|DataDirectory|\\EntityMappingsTests.Types.csv",
"EntityMappingsTests.Types#csv",
DataAccessMethod.Sequential)
]
[TestMethod()]
public void TestMappings () {
Obviously the file is EntityMappingsTests.Types.csv. It should be in the DataDirectory.
Now, in the Initialize method (marked with ClassInitialize) I put that together and then try to write it.
WHERE should I write it to? WHERE IS THE DataDirectory?
I tried:
File.WriteAllText(context.TestDeploymentDir + "\\EntityMappingsTests.Types.csv", types.ToString());
File.WriteAllText("EntityMappingsTests.Types.csv", types.ToString());
Both result in "the unit test adapter failed to connect to the data source or read the data". More exact:
Error details: The Microsoft Jet database engine could not find the
object 'EntityMappingsTests.Types.csv'. Make sure the object exists
and that you spell its name and the path name correctly.
So where should I put that file?
I also tried just writing it to the current directory and taking out the DataDirectory part - same result. Sadly, there is limited debugging support here.
Please use the ProcessMonitor tool from technet.microsoft.com/en-us/sysinternals/bb896645. Put a filter on MSTest.exe or the associate qtagent32.exe and find out what locations it is trying to load from and at what point in time in the test loading process. Then please provide an update on those details here .
After you add the CSV file to your VS project, you need to open the properties for it. Set the Property "Copy To Output Directory" to "Copy Always". The DataDirectory defaults to the location of the compiled executable, which runs from the output directory so it will find it there.
