Presently, if I have a GWO test running in my development or test environments, then I can't very well access all of the content I want (because the control script may redirect me away from the page I want to view).
Sure, I can delete cookies and try the lottery again, but in addition to skewing my test data, that's a hassle. Is there a convenient way to disable GWO tracking and control without disabling javascript? Perhaps a flag I could pass in as GET data?
(I'm aware that I could alter the back end to look for said flag and output or omit the GWO code as required, but that adds an unwanted requirement to the app, which the other developers aren't bound to implement.)

My company hired an agency to create an MQL salesforce object. Its constructed from an Apex class with various triggers.
We no longer have a need for it, and as the standing saleforce admin, there is none at the company who knows Apex. I'm taking classes to learn it, but wanted to check in and see how I can deprecate the object from salesforce by archiving/deleting (or even just commenting out the code) to push the update to production.
Does anyone have insight into how to go about doing this? All of the courses I've taken are basic understanding of Apex and how to write small triggers, classes and queries. The agency who built the class left 0 documentation on its code.
You can't write code in production so whatever you'll try to do - will have to be done in sandbox, tested and then deployed.
There's a way to do a "destructive deployment" and really delete it but you'll need programming tools (VSCode, Eclipse IDE or Ant + Migration Tool). It's bit advanced topic, I'd suggest you hire a dev ;) or try to just comment them out.
In sandbox you can comment out the body (bodies?) of triggers and classes. You shouldn't kill whole file, leave some empty skeletons like
public with sharing class MqlGenerator{
/* kill everything
*/
}
trigger MqlTrigger on MQL__c (after insert){
/* kill everything
*/
}
Of course if there's trigger on Account and it does 10 things, only 2 of them relate to MQL then don't comment everything out ;) It'll be bit of trial and error for you, depends how clean the code is.
You will have to touch triggers, normal classes and likely unit tests too because if they did decent job - there will be tests that verify these triggers do something and now these tests will start to fail.
Add the files to changeset as you go (you do changesets, right? Doesn't sound like you deploy with Git+SFDX for example). From time to time run Apex Classes -> Compile all classes and run unit tests. Some manual testing wouldn't hurt too. If you are unsure what's left you can click on MQL's fields, there's "Where is this used?" button. Or even try clicking delete & repeating until it succeeds ;)
After you deploy this changeset...
If the MQL__c has no triggers (for example it is created in Account updates but itself doesn't have triggers), you might actually be able to delete the object. If there are related triggers, workflows etc SF will stop you. The only way to really delete it would be to run this destructive deploy. It's possible without installing anything, use the link I included and for example workbench would let you make a deployment. But it's bit "pro", if you're unsure start with commenting stuff out and maybe leave the empty skeleton until you're more comfortable. You can always hide the object's Tab, remove right to Read the object and it'll disappear from listviews, reports... it'll be an eyesore only for sysadmins.
If object has to stay around but the data storage is significant you could try truncating the object. If it gives you trouble - Data Loader, export all records (just IDs), then delete. Maybe even with hard delete option so you skip recycle bin.
When developing my react app the app becomes unusably slow with the devtools open in chrome. Works fast and fine with them closed or in incognito mode. I have tried disabling all extensions and had the same problem. This seems to have started happening recently when I updated chrome (now on Version 80.0.3987.132).
I am not really sure where to start debugging this issue but it has become very frustrating to develop on my app.
Any advice or help debugging would be appreciated.
TL;DR: Go to the Sources tab and delete all breakpoints for the site.
I had a similar problem. My site was very slow to load, but only in specific circumstances:
Dev-tools were open.
Tab was in a normal window. (not incognito mode)
Profiling was not enabled.
If (and only if) all three of those conditions were met, the site would load unbearably slowly (15+ seconds; normally ~3s), plus have performance issues for certain operations on the site (like changing which subpanel was open). It was very strange.
Like you, I tried disabling all of my extensions, yet the problem persisted.
Attempt 1: I tried clearing all of the site's cookies and local-storage, using the info/lock dropdown at the left of the address-bar. Suprisingly, that seems to have fixed it! (edit: this was not the root problem; see below for that)
So the problem must be that my site was storing too much data in local storage or something, such that dev-tools was choking on it (but only in specific cases, for some reason). This also matches with the issue resolving in incognito mode: incognito mode uses a "clear slate" for site cookies/local-storage.
Anyway, it's an odd one, but the cookies/local-storage clearing seems to have worked for my case. (If the issue comes up again, and the solution above doesn't fix it, I'll try to remember to mention it.)
Update: Oddly, having the profiler on still speeds things up even after the fix (ie. those three conditions being met still slows down page loading and actions, just much less than before the fix). So apparently the fix merely "reduces the intensity" of the problem rather than fully fixing it; like, by resetting local-storage, it lessens the size of that data, which somehow is a variable affecting the core problem (not yet identified).
Attempt 2: I believe I have found the root problem and solution: I removed all breakpoints for the site, and the slowdown was solved completely. So the problem seems to be that I had lots of unneeded breakpoints set at various places in my website code (some enabled, some disabled). Some of these must have been placed in/near "hotspots" that were getting called frequently. By having the dev-tools open, the Javascript engine must have had to start performing some processing related to the breakpoints, slowing things down.
My guess is that the problem would also be fixed by disabling the "JavaScript source maps" settings (as that's the only thing I can think would cause so much slowdown), but I haven't confirmed this.
This has most probably something to do with this commit, titled "Stop sending profile data when recording is off".
They already know there is an issue with the Developer Tools slowing down and they tried to prevent it by preventing profiling data to be sent via the bridge to the frontend, when not recording.
As reported, it seems the issue is not happening anymore, on the latest version. However, the cause is still unknown.
Try uninstalling the Developer Tools extension, clearing browser cache and then installing it again.
You should probably try using a version other than the one you're using, Version 80.0.3987.132. The app you are trying to develop might not be suitable to the version you are using. Delete the extension you are using, clear and remove every trace of browser cache and then re-download the extension, like what Daniele Molinari said. It might help. If it doesn't let me know. I'll try a different approach.
I am unsure if this is a bug, by design (though I can't see the benefit), or if I am just being dimwitted.
Using Google App Engine development server, v1.9.8, I can only add a datastore entity if another of the same kind already exists. Otherwise the drop-down physically does not show the entity kind.
Further, even on an entity kind that does exist, I can only change attributes (or create them if it's new) if that attribute is not null on at least one of the other existing entities of that kind.
This is annoying, since in order to test things I have to first do:
entityKind(every=Possible, attribute=Set, to=Something, even=If,
i=Dont, yet=Need).put()
Refresh, and then remember to delete this line before refreshing again to avoid duplicating the entry in datastore.
Note though, that if I happen to be testing with only entities that do not use every attribute, I have to keep this dummy one just in case I want the others later.
I must, surely, be missing something here? I can't believe there isn't a way to just create datastore entities without hacking around it like this?
You are talking about creating entities manually using a Dev server. Over the past 4 years of using GAE I wished once or twice that this would be possible, but I never needed this feature. You create entities in your code, and you debug your code if something does not work.
You can (and should) write unit tests to test your code. A proper unit test creates an entity, saves it, reads it, verifies that all the properties are correct, deletes it, verifies that it was deleted. There is no code to cut and paste (or comment/uncomment), and there are no test entities left after testing is completed.
Your mistake is in thinking of the web console as a part of your workflow. It is absolutely not, and not intended to be. It is a vaguely hacked-together tool that allows you to do some basic operations on your data, and nothing else.
Interact with the datastore via code, and leave the web console for simple verifications.
I am currently running a SL3 project where we are in a highly iterative development mode with about 25 active test customers. I am making small changes at a clip of about 4 new builds per day. It is important to know this application is mission critical line of business for these 25 people, it is the tool they use all day to do their work so they are using it constantly and often launch their browser and the app in the morning and never close it until the end of the day.
The challenge is that when I make an update to the application I have no clean way to notify the users, in most cases this is ok as it is rare that I introduce a data contract change or something that would be a classic 'breaking' change to the app/service. Users keep plugging along and will get the change next time they refresh.
Right now we have resorted to emailing everyone and telling them to force refresh or close the browser and log back in.
Surely there is a better way...
Right now my train of thought is to have a method on the server that compares client xap versions and determines if the client being used is the most up to date, if so I will notify the user and make them update.
What have you done to solve this problem?
One way of doing it is to use a push mechanism (I used Kaazing Websoocket Gateway but any would do). When a new version of the XAP is released a message (either manually entered into the system by admin or automated triggered by XAP file change event) would be sent to all the clients. In the simplest scenario some notification would be shown to a user (telling him that a new version is released and the application needs to refresh) and then the app would refresh (by simply reloading the page) saving user's state if necessary.
If I would do this I would just keep it simple. A configuration value in web.config and a corresponding service method that simply returns that value (the value itself could be anything, but a counter is probably wise). Then you could have your Silverlight app poll that service method at regular intervals. Whenever the value changes (which you would do manually when you deploy a new version), just pop up a dialog telling the user to refresh the browser or log in/out. This way you don't have to force them to refresh every time. If you go with the idea of comparing xap file versions they will always be required to refresh, even for non-breaking changes.
If you want to take it further you could come up with some sort of mechanism to distinguish between different severity levels. For instance, if the new config value would contain the string "update_forced", you could force the users to reload the app by logging them out automatically (a little harsh, perhaps). If it contains the string "update_recommended", just show a little icon at the top right corner saying that there is a new version and that they should upgrade in their own time.
Granted, this was targeted at Silverlight 3, but with the PollingDuplex client and such in the newer versions of Silverlight, you could publish an "Update Now" bit to the clients, and build a mechanism in the client to alert the user that there is an update that is now out... that they should update it shortly, etc. You may even be able, through serialization and such, to save the state that they are in when they close the app to reload it.
We've done stuff similar with a LOB app that we built, so that as users are changing things, the rest of the userbase sees those changes immediately. Next up will be putting the flags in to change authorization and upgrades "on the fly" if you will.
Assumption: live/production web app suppresses errors being shown to end-users.
Suppose your tech support team wants to see live data but through the eyes of the development-side of the application (maybe you want to see what errors are occurring, or want to see when you've got an issue fixed using an end-user's data).
Right now we've got one database serving both the dev and live boxes (not my idea - I know it's gross).
Ideas?
Edit: Best/handy tools for implementing your suggestion?
We replicate the data back to a different database. Yes, there is a delay, but it keeps people hands out of the production servers. This also allows us to "hide" information that tech support (and other people for that matter) aren't supposed to see.
In addition to replicating data down, on production, we see who's logged into the application, and if it's a member of the company, send them to the real error page versus the happy kitten playing with a ball of yarn apologizing.
Back up and restore from live to dev on a regular basis (once, twice a day). It doesn't need to be realtime (as you might be entering data from the dev side anyway, which could cause problems).
If you have PCI or HIPAA data, make sure you don't put that in your dev environment -- that might break laws.
I generally like to have a 3-tier system for web development:
Development
Testing
Live
Most of the time testing is an exact copy of the live system, except that errors are turned on, when a new version is about to be moved live it's replaced with the new version BEFORE live is, to detect upgrade issues.
Development is completely separate from live, to allow for major changes to things like the database, or changes to the production environment.
I would firstly make errors are either emailed to someone with details of how the user got there or at minimum logged so you can watch the error log while you perform similar actions to see if you get the same messages in the log.
And yes, copying the database on the dev server/site is probably your only option. You don't want any changes made by the development team to live data and you'll probably also have changes that won't work with the production database at some point.
I wouldn't recommend doing a nightly copy as a developer might be in the middle of some new feature where they have added data and then it's erased that night. I usually copy the production database(s) to dev each time a major version is released. This also allows me to do speed testing with a lot of live data. On some systems I also change everyones password to a default so I can login easily as any user.
If your configuration permits it:
a. Add a logging function (if there isn't one already) to write messages of interest to a log file.
b. Run the unix command
tail -f < logfile.txt
which will stream the growing log file to your console.
