What happened to my Salesforce System.Debug statements?


On our project we have complex report generation which creates a debug log file at the 5MB limit when the Apex Debug Log Level is set to finest.  According to Salesforce:

“Each debug log must be 5 MB or smaller. Debug logs that are larger than 5 MB are reduced in size by removing older log lines, such as log lines for earlier System.debug statements. The log lines can be removed from any location, not just the start of the debug log.“


If you just want to see the debug statements, simply log at the error level and then set everything else to none.

    System.debug(LoggingLevel.ERROR, ‘some logging message’);

Debug Levels
  • Database : None
  • Workflow : None
  • Validation : None
  • Callouts : None
  • Apex Code : Error
  • Apex Profiling : None
  • Visualforce : None
  • System:  None
  • Wave: None
  • Nba: None

If you want to debug in Visual Studio at the Apex finest level, break your code up into small testable pieces so that you can pinpoint errors and the log files can be under the 5MB limit.  The Single Responsibility should be your best friend when working in Salesforce.

Augmenting Salesforce CLI Commands for VS Code


I have been working with the Salesforce Extension Pack for VS Code and I have been mostly pleased with the capabilities.  On my current project, I find myself constantly switching between orgs.  I was tired of typing in the command to list out the current org and the command to switch the current org.  
There is a great hotkey VS Code extension called terminal-command-keys that allows you to create a hotkey that executes a terminal command.  The Salesforce CLI with hotkeys; what could be better!
Here are the steps to use
  1. Install the VS Code extension terminal-command-keys
  2. Edit your keybindings.json by pressing Ctrl-Shift-P on the PC or Command-Shift-P on the Mac.  Edit the file on the right



Add a command to list all your orgs by pressing Ctrl-Shift-l
    {
    "key" : "ctrl+shift+l",
    "command": "terminalCommandKeys.run",
    "args" :
        {
            "cmd": "sfdx force:org:list",
            "saveAllFiles": false
        }
    },

Add a command to upload the current file by pressing Ctrl-Shift-u
    {
        "key": "ctrl+shift+u",
        "command": "terminalCommandKeys.run",
        "args": {
            "cmd": "sfdx force:source:deploy --sourcepath  ${file} --loglevel fatal",
            "newTerminal": false,
            "saveAllFiles": true,
            "showTerminal": true
        }
    },

Add a command to switch to your development org.  In my case, the alias is BossSand. Replace with the alias for your org.
    {
        "key" : "ctrl+shift+d",
        "command": "terminalCommandKeys.run",
        "args" :
        {
            "cmd": "sfdx force:config:set defaultusername=BossSand",
            "saveAllFiles": false
        }
    },

Add a command to switch to your test org.  In my case the alias is BossStage. Replace with the alias for your org.
    {
        "key" : "ctrl+shift+v",
        "command": "terminalCommandKeys.run",
        "args" :
        {
            "cmd": "sfdx force:config:set defaultusername=BossStage",
            "saveAllFiles": false
        }   
    }

Debugging Salesforce Tests with VS Code

Debugging in Salesforce is relatively new and it immature compared to debugging in Visual Studio or Eclipse.  Even Microsoft Access has a better debugger than Salesforce.  Essentially logs files are created when running tests and then the log files are used to step through the code.  It is after the fact debugging, you cannot change the path that the code has gone.

If you haven't already, set up VS Code for Salesforce


  1. Click the Debug icon
  2. In the drop down list at the top under Debug, Add Configuration.  Select Apex Replay Debugger
  3. Make sure that you have pulled all your code and tests down from source control or from your org.
  4. Using Ctrl-Shift-P on Windows or Command-Shift-P on a Mac, select SFDX: Turn On Apex Debug Log for Replay Debugger
  5. Set a break point in your test
  6. Run your test by clicking Run Test above the test method name in VS Code 
  7. Using Ctrl-Shift-P on Windows or Command-Shift-P on a Mac, select SFDX: Turn Off Apex Debug Log for Replay Debugger
  8. Using Ctrl-Shift-P on Windows or Command-Shift-P on a Mac, select SFDX: Get Apex Debug Logs
  9. Click the Debug icon
  10. Click the Launch Apex Replay Debugger
  11. You can see local variables on the left and you can step into code

Setting Up VS Code with Salesforce

These are step by step instructions to get VS Code working with Salesforce.


  1. Go to your Sandbox, under Setup search for Dev Hub.  Enable Dev Hub and GA.  This will allow you to create scratch orgs.
  2. Install the Salesforce CLI which will allow you to push and pull code and run tests:   https://developer.salesforce.com/tools/sfdxcli
  3. Install VS Code which is now the standard for editing code for Salesforce:  https://code.visualstudio.com/download
  4. Install Java if you do not have it installed yet.  The Salesforce Extension Pack requires it.  https://www.java.com/en/download/
  5. Install the Salesforce Extension Pack.  In VS Code, click the extensions icon and search for Salesforce Extension Pack.
  6. Install Lightning Web Components extension in VS Code
If your Salesforce code is in your org and not in source control then you are in Classic Development and not Salesforce DX.  

Classic Development Mode (directly interact with an Org)



* After creating the project, create these folders under the default folder before doing a Retrieve Source From Org:  

  • classes
  • objects

Salesforce DX Mode (your source is in GitHub or Bitbucket)

Example of cloning a repository, creating a scratch org and pushing the code

git clone https://github.com/dreamhouseapp/dreamhouse-sfdx
cd dreamhouse-sfdx
sfdx force:config:set defaultdevhubusername=your@username.com
sfdx force:org:create -a dreamhouse -s -f config\project-scratch-def.json -d 7
sfdx force:source:push
sfdx force:user:permset:assign -n dreamhouse
sfdx force:org:open -p /lightning/page/home

Using Caching in the .NET Framework

Caching is easy to use in the .NET Framework

According to Microsoft:
"In the .NET Framework 3.5 and earlier versions, ASP.NET provided an in-memory cache implementation in the System.Web.Caching namespace. In previous versions of the .NET Framework, caching was available only in the System.Web namespace and therefore required a dependency on ASP.NET classes. In the .NET Framework 4, the System.Runtime.Caching namespace contains APIs that are designed for both Web and non-Web applications."

Here are a couple methods to Load and Save from the Memory Cache.  If the value is not found, it will be null.  

public static class Cache
{
        public static TResult Load<TResult>(string cacheKeyName)
        {
            ObjectCache cacheInstance = MemoryCache.Default;
            return (TResult)cacheInstance[cacheKeyName];
        }

        public static T Save<T> (string cacheKeyName, DateTimeOffset expirationDate, T value)
        {
            CacheItemPolicy cacheItemPolicy = new CacheItemPolicy();
            cacheItemPolicy.AbsoluteExpiration = expirationDate;
            ObjectCache cacheInstance = MemoryCache.Default;
            cacheInstance.Set(cacheKeyName, value, cacheItemPolicy);
            return value;
        }
}

Example Call to Load and Save


Here is an example of using the load and save with a stopwatch so that the time saved can be shown:


        [Test]
        public void SimpleLoadAndSaveTest()
        {
            Stopwatch watch = Stopwatch.StartNew();
            string json = Cache.Load<string>("JsonValue");

            if (json == null)
            {
                json = GetJsonFromWebService("cf4174ce-96d2-495c-b58a-427d35f64a20");
                Cache.Save("JsonValue", DateTimeOffset.Now.AddMinutes(20), json);
            }
            watch.Stop();
            Console.WriteLine(watch.ElapsedMilliseconds);

            watch.Restart();
            json = Cache.Load<string>("JsonValue");
            watch.Stop();
            Console.WriteLine(watch.ElapsedMilliseconds);
        }

        public string GetJsonFromWebService(string value)
        {
            Thread.Sleep(1000);
            return "{ \"Value\" : \"" + value + "\" }";
        }

Cache Class


I have created a larger caching class where methods can be passed into shorten the code:


    public static class Cache
    {
        public static TResult Load<TResult>(string cacheKeyName)
        {
            ObjectCache cacheInstance = MemoryCache.Default;
            return (TResult)cacheInstance[cacheKeyName];
        }

        public static T Save<T> (string cacheKeyName, DateTimeOffset expirationDate, T value)
        {
            CacheItemPolicy cacheItemPolicy = new CacheItemPolicy();
            cacheItemPolicy.AbsoluteExpiration = expirationDate;
            ObjectCache cacheInstance = MemoryCache.Default;
            cacheInstance.Set(cacheKeyName, value, cacheItemPolicy);
            return value;
        }


        public static TResult Load<TResult>(string cacheKeyName, int expirationMinutes, Func<TResult> serviceFunction)
        {
            return Load<TResult>(cacheKeyName, DateTimeOffset.Now.AddMinutes(expirationMinutes), serviceFunction);
        }

        public static TResult Load<TResult>(string cacheKeyName, int expirationMinutes, Func<string, TResult> serviceFunction, string stringArg)
        {
            return Load<TResult>(cacheKeyName, DateTimeOffset.Now.AddMinutes(expirationMinutes), serviceFunction, stringArg);
        }

        public static TResult Load<TResult>(string cacheKeyName, int expirationMinutes, Func<long, TResult> serviceFunction, long longArg)
        {
            return Load<TResult>(cacheKeyName, DateTimeOffset.Now.AddMinutes(expirationMinutes), serviceFunction, longArg);
        }

        public static TResult Load<TResult>(string cacheKeyName, int expirationMinutes, Func<int, TResult> serviceFunction, int intArg)
        {
            return Load<TResult>(cacheKeyName, DateTimeOffset.Now.AddMinutes(expirationMinutes), serviceFunction, intArg);
        }

        public static TResult Load<TResult>(string cacheKeyName, DateTime expirationDate, Func<TResult> serviceFunction)
        {
            return Load<TResult>(cacheKeyName, new DateTimeOffset(expirationDate), serviceFunction);
        }

        public static TResult Load<TResult>(string cacheKeyName, DateTime expirationDate, Func<string, TResult> serviceFunction, string stringArg)
        {
            return Load<TResult>(cacheKeyName, new DateTimeOffset(expirationDate), serviceFunction, stringArg);
        }

        public static TResult Load<TResult>(string cacheKeyName, DateTime expirationDate, Func<long, TResult> serviceFunction, long longArg)
        {
            return Load<TResult>(cacheKeyName, new DateTimeOffset(expirationDate), serviceFunction, longArg);
        }

        public static TResult Load<TResult>(string cacheKeyName, DateTime expirationDate, Func<int, TResult> serviceFunction, int intArg)
        {
            return Load<TResult>(cacheKeyName, new DateTimeOffset(expirationDate), serviceFunction, intArg);
        }

        public static TResult Load<TResult>(string cacheKeyName, DateTimeOffset expirationDateOffset, Func<TResult> serviceFunction) 
        {
            TResult cachedObject = Load<TResult>(cacheKeyName);

            if (cachedObject == null)
            {                
                cachedObject = Save(cacheKeyName, expirationDateOffset, serviceFunction());
            }

            return cachedObject;
        }

        public static TResult Load<TResult>(string cacheKeyName, DateTimeOffset expirationDateOffset, Func<string, TResult> serviceFunction, string stringArg)
        {
            TResult cachedObject = Load<TResult>(cacheKeyName);

            if (cachedObject == null)
            {
                cachedObject = Save(cacheKeyName, expirationDateOffset, serviceFunction(stringArg));
            }

            return cachedObject;
        }

        public static TResult Load<TResult>(string cacheKeyName, DateTimeOffset expirationDateOffset, Func<long, TResult> serviceFunction, long longArg)
        {
            TResult cachedObject = Load<TResult>(cacheKeyName);

            if (cachedObject == null)
            {
                cachedObject = Save(cacheKeyName, expirationDateOffset, serviceFunction(longArg));
            }

            return cachedObject;
        }

        public static TResult Load<TResult>(string cacheKeyName, DateTimeOffset expirationDateOffset, Func<int, TResult> serviceFunction, int intArg)
        {
            TResult cachedObject = Load<TResult>(cacheKeyName);

            if (cachedObject == null)
            {
                cachedObject = Save(cacheKeyName, expirationDateOffset, serviceFunction(intArg));
            }

            return cachedObject;
        }

    }

Example using Func with Caching

The function can be passed in that will fill the data if it does not exist in the cache.

        [Test]
        public void CacheTestUsingFunc()
        {
            Stopwatch watch = Stopwatch.StartNew();
            string json = Cache.Load<string>("JsonValue", 20, GetJsonFromWebService, "cf4174ce-96d2-495c-b58a-427d35f64a20");
            watch.Stop();
            Console.WriteLine(watch.ElapsedMilliseconds);

            watch.Restart();
            json = Cache.Load<string>("JsonValue", 20, GetJsonFromWebService, "cf4174ce-96d2-495c-b58a-427d35f64a20");
            watch.Stop();
            Console.WriteLine(watch.ElapsedMilliseconds);
        }

        public string GetJsonFromWebService(string value)
        {
            Thread.Sleep(1000);
            return "{ \"Value\" : \"" + value + "\" }";
        }
