With a git repository setup for my iPhone app, is there a way to gain access to the last committed version of a file outside of XCode? Can I find the previous version somewhere on the hard drive, or perhaps piece the file together somehow? The current version of the file is now corrupt (see story below for how this happened if interested), and I'd very much like to retrieve the changes I made since the last time I was able to backup the files outside of git. I don't have the ability to access anything in XCode or run anything on the Mac outside of what's available through Max OS X Installer, so I'd like to access the previous version of the file if that is possible.
Story that pisses me off begins here:
On a recent 6 hour flight, I took my MAC with me on the plane, committing changes to the git about 2 times during this period. Everything functioned fine on the MAC all the way until we had to shut down all electronics at the end of the flight. At that time, I told the MAC to shutdown, but it froze instead. Wanting to avoid an airline incident, I forced the computer to shutdown by holding the power button after waiting for over a minute.
When I turned on the computer later that night, it would no longer boot, instead freezing on the Apple logo and the spinning gear. I used my install disk to bypass logging in and accessed Disk Utility, which proceeded to FAIL repairing my drive. The hard drive still mounts, so I'm able to get into my files. I accessed the absolutely essential file needed for my app, and when I opened it on my Windows machine it contained garbage. Of course most of the other files were all fine :-/
Story that pisses me off ends here.
So, I'm still trying to fix my stupid MAC, but before proceeding and possibly needing to wipe the drive, I'm trying to grab all the files I can, so any help is definitely appreciated.
To wipe out the current changes and see the most recent committed version,
git checkout HEAD .
To wipe out the current changes and see the previous committed version,
git checkout HEAD^ .

I have a question for Local history
Is local history transfered via telemetry?
If yes, can I receive my local history data via email or other ways.
I have turn on enable telemetry all since use VSCode.
Reason 1
I had a planned to develop a python module using Local history files
which time spent and more information per project daily.
Reason 2
Even though I had backup to D drive,but now impossible.
Due to initialization my all local drives during Windows 11 installation.
It was my fault, didn't check the options.
Please let me know my question.
PS.
Local/User history is VSCode function which tracking per file.
Can check in timeline tab in VSCode
The location of Local history is as below in case Windows system
%APPDATA%/Code/User/History
%APPDATA% = C:/Users/{USERNAME}
Thank you.
I see that there are way to Get Get-AppxPackage or Remove Remove-AppxPackage UWP app from windows 10 using PowerShell.
I am wondering if there is a way to reset a UWP app? I require it for automated testing, I would rather reset the UWP app than uninstall and install again, as that would slow down the testing.
If you're looking to clear your package's ApplicationData then you want
appdata = Windows.Management.Core.ApplicationDataManager.CreateForPackageFamily(pkgfamilyname)
appdata.ClearAsync()
See MSDN for ApplicationDataManager.CreateForPackageFamily() and .ClearAsync()
Powershell has no 'await' affordance last time I looked (though it's been a while) so not so viable. If you're looking to muck with applicationdata you may find APPDATA.EXE handy. You can probably guess why I wrote it... :P For instance
APPDATA.EXE Clear foo.bar_1234567890abc
If you're looking to reset a package to its initially installed state, then no, there is no API other than uninstall + install
Remove-AppxPackage foo.bar_1.2.3.4_x86__1234567890abc
Add-AppxPackage foobar.msix
Settings' Reset option for an installed package essentially does that just slightly more efficiently. You're still going thru the full deregister and uninstall the package and then install and register it for the user so it may not be instantaneous. But that's the only way to truly reset a package to its initial state. Windows has various forms of user data associated with a package (ApplicationData, IndexDB, more) as well as system state cribbed and wired up when a package is installed for a user (what is the package, where's it live, that the user has it, that it's status is not tampered or otherwise unhealthy, more). The only way to truly 'reset' that to the initial state is a full remove then add.
If you just need to wipe appdata then .ClearAsync is the ticket.
I am not aware of any command that would do that for you (except for the UI available in Settings app). However, you may write a PowerShell script that would clear up the application data files in the app's folder (this is not an official solution, but seems to work based on my trials).
Go to
C:\Users\{your_username}\AppData\Local\Packages\
And find your app's folder there. There are several folders containing the application state.
The nuclear option is to just delete all the folders. Then the app will crash once on startup, then the system will automatically reset it and restore the folders.
The less invasive option I have now tried seems to be to keep the folders and just delete their content, except for the AC folder, which seems to be system protected. When I tried this with my app, it launched successfully without crashing and system recreated the state files anew on its own.
The rest of application files lives in C:\Program Files\WindowsApps, but those are just application DLLs and content files and are read-only, so they should not affect the app state at all.
You may want to perform additional deletion if you use a shared publisher folder.
For windows 10 build 2004+ there seems to be a powershell command Reset-AppxPackage now.
UPDATE
My mistake, it is available from version 20175 onward. So, should be available in 20H2.
I'm working on a disconnected network, so some options are a bit limited. Also, we have SAs who handle stuff like system updates (so, for instance, it is possible that there was a system update in there that I know nothing about).
However, I had 1.33.1, then 1.34.0, then 1.38 versions of VSCode working on my (Windows 10) machine. One day, for no apparent reason (I hadn't just installed something, for instance), 1.38 stopped working. It wouldn't even start up. Running 'Code --verbose' from the command line produced no output (the mouse cursor turned briefly to a spinner, but nothing even showed up in Task Manager, let alone something like a splash screen).
I did get an error message in the Application log, which included the lines (more or less; remember, no cut-n-paste possible):
Faulting Application Code.exe, version: 1.38.0
Faulting module ntdll.dll, version 10.0.16299.936
Exception code: 0xc0000374
Faulting Application path: c:\Program Files\Microsoft VS Code\Code.exe
Faulting module path: c:\Windows\System32\ntdll.dll
Re-installing VS Code (with or without system restart after uninstall) did nothing.
Removing all extensions (we have a bunch) did nothing
Installing 1.39.2 did nothing
The only good thing is that I can still run 1.34.0, if I reinstall that (did not try 1.33.1, and I don't have any in-between versions from 1.34 to 1.38 to try). So at least I'm not completely shut out.
I also tried deleting basically all of workspaceStorage, to no effect. Nor did renaming my storage.json.
The biggest weirdness, to me, is that the path to ntdll.dll is in System32, rather than in SysWOW64 (is there some way to force usage of the latter?). Second, why did 1.38.0 work just fine for a while, and then stop.
So, I'm curious if anyone else has seen this problem, and/or if anyone has any idea what else could be done to get more insight into what's causing this.
(edit: I plan to file bug for VSCode, but been waiting on confirmation email to finish creating my github acct for some time now. sigh)
I've had exactly the same problem twice. I'd been running the application since June 2019 and then in March of this year, Yep! Exact same problem as you encountered. A simple reinstall fixed that, but I've had the same problem again today and after some investigation, Windows 10 was telling me that I didn't have the right permissions to access the item (this is using the Owner's account!). Attempting to reinstall failed, with errors stating that the file / directory all ready existed and couldn't be overwritten or renamed. Attempting to un-install the application was only partially successful with the executable code.exe still remaining afterwards. The only way I managed fix it this time was to reinstall to a directory with a different name. Surprisingly though, all the existing workspaces, projects and extensions even were intact and the application opened where I had left off as though nothing had happened. This is a little worrying I have to say! But that's how I fixed it this time.
I'm trying to develop a little toy PHP project, and the most convenient location to run it is on a shared host I happen to have for my ill-maintained blog. The problem with this is that I have no way to run Subversion on this shared host, nor do I even have SSH access to be able to access an external repository from the host. Had I been thinking straight a few months ago when the hosting was up for renewal, I probably should have paid a couple extra bucks to switch to something a bit better, but for now I can't justify throwing money at having a second host just for side projects.
This means that a working copy of my project would need to be checked out to my laptop, while the project itself would need to be uploaded to the shared host to run. My best option seems to be creating a virtual machine running Linux and developing everything from in there, but I know from past experience that the extra barrier that creates, small though it may be, is enough that it puts me off firing the VM up just to do a couple minutes work to make some minor change I just thought up. I'd much prefer to just be able to fire up my editor and get to work.
While I'd imagine I'm not the first to encounter such a problem, I haven't had much success finding a solution online. Perhaps there isn't one beyond the VM or "manual mirroring" options, but if there is I'd expect StackOverflow to be the place to find it.
Edit: There's some confusion, it seems, so let me attempt to clarify. The shared host here is basically my dev server, but it has no svn or ssh. In other words, I can svn checkout to my laptop, but I can't run that on my shared host. Similarly, I can run/test my code on the shared host, but I can't do that on my laptop (well, I technically could, but it's Windows, and I don't want to worry about Win-vs.-Linux differences with PHP, since I do want this to become public at some point, and it will certainly be Linux-based at that point).
You might consider writing a post-commit hook to automatically upload the code to your host, so that any time you commit a change, a script executes that:
Checks out a copy of the code into a temporary directory
Uploads that code via FTP (or whatever your preferred method is) to the shared host
Cleans up after itself, optionally informing you via e.g. email when the transfer is successful
Subversion makes enough information available to these scripts at runtime that you could get more sophisticated and opt only to upload the files that changed or alter behavior based on specific property changes, for instance, but for a small project the brute force "copy it all" approach should be fine.
Firstly, I'm not sure if this belongs here or programmers. Please move if it needs to be there.
I am mostly a hobbiest web developer, with a bit of freelance sidework. I program anywhere I can, from a laptop on the go to my home PC. I've pretty well settled on Net Beans as my IDE, and xampp for my test environment. My question is how do I best synchronize changes between my different PCs?
I started out FTPing changes to a "dev" area on my webserver, then FTPing them down to my other PC, but that's sort of a pain. Lately I have started using dropbox, which takes a lot of the pain out, but still isn't quite as seemless as I'd like.
Has anyone come up with a bulletproof way to easily ensure you're always opening up the latest version of your files across multiple PCs which aren't necessarily always (but sometimes are) on your home network?
Free is a necessity.
I personally use Subversion.
It integrates easily with Netbeans or Eclipse, and you say you've got a webserver, which I presume is Linux based? It's easy to set up in any Linux environment, though I think it can also be set up in a Windows environment.
Then you just run an update on your code when you want to get the latest version, do checkins when you like it, and you can always go back to earlier code (like if you tried a two day experiment that didn't work out and now want to delete it all and go back to what you had that was working).
Use some version control system. If you are new to this stuff Subversion would be probably the easiest to start with and it is very well intergrated with Netbeans.
You may set up repository on your own server or use some external service - there are a lot of them and almost everyone offers some free plan to start with. I'd be glad to give you some pointers if you like.
Learn to use a version control system.
www.github.com is free for open source projects, but must pay for private source repositories and also closed source projects, hurray.
http://unfuddle.com uses subversion, and is free for 200Mb of private source.
You may find some of the links in this thread useful.
A very simple and efficient way is to open an account on dropbox.com.
I disagree with a lot of the answers here (A lot are pretty old). Git/SVN is not a synchronization solution (nor a backup). It is just a version control system. (But if done correctly you can use git and a sync tool at the same time.)
By using git for synchronization you get the following side effects:
polluted git log: e.g. git commit -am 'synced files'... 'synced files again', 'synced from laptop', 'synced from desktop'
a substandard workflow: every time you leave your workstation or laptop you have to remember to git commit and push. This takes time and mental energy
Instead, I would recommend a solution that offers a continuous sync of your files to a central server. You can close your laptop within five seconds (maybe less) and your changes are propagated to a central server awaiting to sync to other devices when they come online. One priviso: you need to make sure you are not syncing folders like .git so a sync from your laptop .git for your project doesn't corrupt your .git on your desktop. Some options are:
Synology Cloudstation Drive - I can speak personally to this one. It excludes all "." files by default, and syncs at every file change. As soon as you save the file it is synced
NextCloud/OwnCloud - I now use Nextcloud, sync all computers, and make sure to exclude .git so that each git repo will track independent changes against origin BUT still be synced between devices.
Google Drive
Dropbox
You can set up a web-based source repository on something like http://www.github.com, and be able to access it from any computer.
