I'm using JavaHg in order to build a customised GUI interface. I was able to clone via code as follows:
BaseRepository repo = Repository.clone(new File(checkout_folder), url);
However, this being a GUI app, it just stalls until the clone is complete. Is there any way to do this clone command while also allowing the GUI to monitor its progress?
My gut feeling is telling me to take a look at the MercurialEclipse plug-in and see how they do it there, but if anyone can suggest an approach, I'd be glad to hear it.
Regards,
Gurce
EDIT:
Thanks for the info on both perspectives, one for the reality of the present situation, and for the suggestion of a night-rider progress bar.
I recently opted for a dodgey workaround approach, which I seem to be getting away with for now.
Since I'm hosting my mercurial projects on a hgweb server, I tried doing it this way:
A checkout (ok ok, clone! :)) is triggered in my app
My app visits the server via ssh and runs a "du" command on the bare repository for the project intending to be checked out
So then my app uses the returned total-disk-space-used by that bare-repo as an estimate of the total disk-space the final checkout should have on the local working folder
My app then polls the local working folder once a second with the "du" command, to see amount of disk-usage the checkout/clone is currently consuming
I use this du result versus the du result from the server to display my progress bar
It's not 100% accurate, but oh well, it seems to do the job ok...
Currently JavaHg doesn't support showing progress of long running operations
with a work thread you can solve the hanging part. i'll check the monitoring, but i think a night rider, work in progress bar will do just fine. you'll have to start a thread to handle the communication and let the main thread go on and handle the actions on the gui.
there are two options to see if the cloneing is over:
-via a callback method (this is the nice, bigbook style way to do this)
-check upon the work thread periodicaly (not so good, but if you're into while cycles and hate callbacks it'll do the trick)

I have encountered a critical issue that Unity Editor freezes. I've spent many hours debugging step by step of my codes but still can't find where the problem is. So I think maybe I should try thinking from another angle, generally speaking what reasons would cause Unity Editor freezes and not responding?
I can't find a general case discussion about this topic.
From my experience, infinite loop is one reason for sure. Deadlock is critical issue, but not sure if it causes Unity Editor freezes. Unity Editor bug that I encountered only makes the whole editor crashes, instead of freezing. Any other experiences are welcomed. Thank you!
In such case, what kind of tools or methods could I use to debug it? Right now since the editor freezes I can't use "print" to find out what happens after it freezes. So I use Visual studio to debug the Editor thread, in this way I can see all the prints that I wrote. It appears the game is still running, only the editor not responding. And I can use VS click "attach to Unity and play" and put some debugging points, then debug step by step.
The first thing that I would check out is for an infinite loop. At the hang/freeze moment, you can attatch the debugger of your choice and pause the execution. In the case that it is an infinite loop that it is executing, at the exec time pause you might find the execution in a forever running while (true) {...}
Other thing that I would check is the plugins in use. Several Unity plugins like Parse, FMOD, UMP (Universal Media Player), ZFBrowser, or Embedded Browser are using native threads. It’s an issue when a plugin ends up attaching a native thread to the runtime, which then does blocking calls to the OS. This means Unity can't interrupt that thread for the debugger (or domain reload) and hang. Source
To check that you can check the active threads in the visual studio command window af the freeze is reproduced:
View->OtherWindows->CommandWindow and type in this command:
Debug.ListCallStack /AllThreads /ShowExternalCode
In the stack you can check if some thread is there with no need, or if its related with the plugins mentioned above.
Also an interesting point is to check in the windows task manager (in the case that you are using windows) if the CPU usage is to 0%. It can lead you to the type of hang that is taking place.
Good luck.
Edit: I forgot to mention, you need to check also the unity logfiles
I notice this all the time, and its super frustrating.
Unfortunately, this could be any number of issues. I notice this issue most often when working in projects that are made for the Universal Windows Platform.
Try using the Task manager to monitor specific processes / threads running.
Some follow up questions:
What platform is your project currently targeting?
What version of Unity are you running? Have you tried other versions?
What are your computers specs? Is the OS up to date? Graphics Drivers?
Does it happen (or happen more often) when an external code editor is open? Perhaps try going to Preferences>External Editor > Regenerate Project files.
Are you using Unity Collab by chance? I've had issues where collab is stuck trying to communicate with Unity Servers / looking for changes. Try logging out of your Unity account through the editor, and log back in.
Have you tried looking for a Unity editor crash dump, or error log files? I think they can be found here C:\Users\username\AppData\LocalLow\Unity by default. Those files may give you more specific data concerning your problem.
Unity's new versions are getting more slower and slower. From my experience 2019 versions are the best and more stable.
I solved my issue. It's fundamentally an infinite loop.
It's not a simple case such as "while(true)". I'll try to explain.
My game was a PvP game, and I'm making a local AI. Usually my design pattern works fine, however I just turned off the simulation of "AI thinking time", and since the AI codes and server codes all run in local mode, the transmitting of data between server and client are replaced by local method call(meaning instantly executed before everything else).
There is a loophole in my server code. I use "Update" and a flag on server to change a specific game state, however in this particular case, it got into an infinite loop because the local method call is executed before the "Update". And because my AI now doesn't need real time to "think", it "acts" and transmits the event data to server right away. And since the transmitting doesn't need time any more, it calls the server method instantly, hence forming the infinite loop.
Very new to Google Actions. Testing out tutorial stuff.
I have tried this in a couple of test projects just to double check. After initial run of any project I do not get any updates on draft projects. No changes show up in draft projects for me for both simulator and real device.
Started new project
Even blank project has basic conversation telling you where to add things next.
Change text.
Notice prompt does not change in testing environment.
In below pictures I have changed the words "hello world" with "Hey Dude" for both fulfillment and console output. I would expect Testing Prompt to respond with "Hey Dude from fulfillment and Hey Dude from the console!" But it does not. Instead it does not reflect any recent changes.
I think there may be two slightly different (but sometimes related) issues going on here.
The first is that there are known problems with the simulator being slow to pick up on updates, or them not seeming to show up. The second has to do with making sure you're deploying changes from the build-in code editor.
I don't have a clear answer to the first problem, although I know they're looking into it. I find that I can make some changes and they may not be noticed, but I know they have been picked up if I see the "Your preview is being updated..." spinner appear. There are other spinners that sometimes appear, but unless it explicitly says that it is being updated - the updates aren't always picked up. (Sometimes they are, however.)
Usually, if I don't see this, I'll go back and force an apparent change (delete a character from a webhook handler name, then add it back) and go back to the simulator. In general, this time it will say it is updating.
If you're using the Cloud Functions editor, you need to do three things:
Save the changes. You'll do this by clicking the "Save Fulfillment" button, but this only saves it so you can leave the editor. It doesn't mean that the simulator has access to it yet.
Deploy the changes. This deploys your code to Cloud Functions so they can be run. Note in the illustration that it says the code is saved, but not yet deployed.
Wait till the changes are fully deployed. Deploying takes time, and until it is completed, it won't be available in the simulator. While deploying, it lets you know.
Once it has deployed, however, the message changes, and you the impacts should be available through the simulator (although you may still need to see the "being updated" message to be sure).
Remember, however, that you don't need to use the "Cloud Functions editor" in order to deploy a webhook. You can deploy a webhook on any web server where
The host is public (so has a public IP address that Google can reach)
It can handle HTTPS with a non-self-signed certificate
You can even deploy yourself to Cloud Functions for Firebase, which is the same service that the Actions Builder uses. This way you have the URL set once in the Actions Builder and, once it is set, you won't need to change it.
But you'll still be able to change your code by managing your own deployment separate from Actions Builder.
In Eclipse Neon I started getting a dubious background job called "Analytics Ping", if I build (ie. save a file!) or synchronise with eGIT. I believe this is due to GWT (2.8.0). It appears to be poorly implemented in that:
1) Other background jobs queue unnecessarily behind it (it prevents me from updating/committing code!).
2) Like many other background jobs in Eclipse, it doesn't respond to cancellation requests.
Thus, if it has problems "pinging" back, it prevents me from working (And why does it need to ping for every file save?!).
Does anybody know how to switch this off for these versions? Thank you.
In Eclipse Preferences > GWT, disable "Share anonymous usage statistics of the GWT Eclipse Plugin..."

We have a new server running and we got some new programs doing import routines. So far so good... But there is one program that is put into autostart folder. So it doesn't run until admin logs in and it stops if we logout.
I'd like to put this one into a seperate session so it may work without any interaction by simply starting it with the task scheduler at startup. Is this the right way to do this? Is it safe if I log in later and log out?
Many thanks!
Edit: The applications shows as a symbol in the task bar if running, it can be configured by this. Anything I must know about this if I change?
Edit: It is not my application, I cannot rewrite it as a service.
I successfully added the application by using task schelduler on startup. Login and logout will not quit the application but no symbol is shown. Please add details to my side questions and I'll mark your answer as the accepted one.
Edit: Ended up using this one. If I have to configure, I stop the application in task manager and start it again by link. After that I quit the application and restart it by task scheduler manual start.
You need to run your program as a Windows Service. One way of doing it is using the sc.exe program:
> sc create <new_service_name> binPath= "c:\myapp\myapp.exe"
You can read about it here.
You need to separate your application in two.
To allow it to run without a user session, you need a windows service. That should handle all the background stuff. You can then register the service and set it to start when the system starts.
To allow it to have a UI, and show up in the notification area, you need a windows application. This will be in autostart as usual, and will communicate with the service - for example, over named pipes.
While it is still (barely) possible to run an UI application without a user session, it's only maintained for backwards compatibility, and already shows a lot of problems. It will likely be removed altogether in the future, because it breaks quite a few contracts. Do not rely on hacks like this.
I also used the task scheduler to create the application at system startup. It should be noted that if you want to use for mining, you have to disable an option in "settings" where it says that if the application lasts more than three days in a row it will end.
It really works wonderfully!
it is a old question but I recently solved in another way...
(before I was using a scheduled-task for startup but this gave me diverse problems with lots software...)
Some programs also for diverse reasons must be run at a user level... or even inside a specific user session...
So the best way I found was to use a tool like Sysinternal/Autoruns to program the auto-logon to a specific user (it is a registry setting)... and in the startup-folder of that user (or any other "autorun/autolaunch" task)... run a script that first locks the screen... and next runs the other intended programs... that will run under that user profile...
so you can choose a standard user or a administrator... or even launch programs from a standard user in adminsitrator mode...
I hope will help...
This "hack" solved me many problems with startup apps...
I could not get the "sc create" command to work. Instead I manually edited the registry using regedit. I added a new key in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services.
I used the following page to figure out required parameters and their values. Note that the names do not map.

Old question, but for anyone that stumbles here. Use srvany to set the program as a custom service.
Note that when you do this with for example dropbox, googledrive, etc., you will need stop the service, then open the program normally to make changes like password, updates, etc.
below is a well enough intro.

Convert user application to Service and Register it using Regsvr32 or installutil.exe. It will start the service using SYSTEM user account. Which is a high privilege account.
Note : You can`t run any Window based application. Even a Message only window.
I have some code that unpins and pins items from the task bar and start menu, which I run using Remoting, as a means of cleaning up lab machines between sessions. It works great, other than I need to log off and back on to see the changes. This is somewhat similar to another bit of code I have, which changes the icon of a shortcut in order to "badge" it as an updated file. That code also requires a refresh, but there I am able to use a technique I found here...This does a refresh of Explorer and the desktop shortcut shows up correctly. However, the same code does not do a refresh of the task bar it seems. I also found this, which also seems to not impact the Taskbar.
Also, this is related to the Remoting, because when I run the same code "locally" no refresh is needed. So, curious if anyone knows a way to directly refresh the task bar (and Start Menu) via Remoting? Or am I going to need to brute force it and just log the user off?
Well, this is interesting, and proof that sometimes we look for complex solutions to simple problems. All the examples I found are pretty complex, but what works fine is simply this...
Stop-Process -processName: Explorer
No need even to restart, as Explorer restarts automatically and near instantly.
