I accidentally did something to my git repo and I don't know if I can save my project at this point...
I had a bunch of changes that I made. Then I wanted to delete my last commit so that I could make this new commit instead. I forgot to do git stash. So when I ran git reset --hard [second-to-last commit] it erased everything I had done. It was stupid, but is there anything I can do to rescue my recent work?
I'm using Eclipse IDE.
Short answer for git, NO.
It is impossible to recover file that you did not add or stash
In general the best way to handle these kind of problem is to rely on the IDE instead.
In Eclipse, you could look under this path
.metadata/.plugins/org.eclipse.core.resources/.history/
So, you could use those commands to find the most recent changes,
cd .metadata/.plugins/org.eclipse.core.resources/.history/
ls -al * | grep "<today's date>" | grep "r\-\-" | sort -k 6
Note that you will have to replace "<today's date>" with "Jul 27" for example.
Then you could use
find . -name <filename>
Note that you will have to replace "<filename>" with something like "7098a672a2bc00111703c0e5cbee369d" found with the previous command.
For more info look at this.
Unfortunately, git has no way of knowing about the file contents that you didn't commit or stash. This means you cannot restore your changes with git. Other tools might be able to help. For example, IntelliJ has a "Local History" feature that tracks all saved changes. Perhaps your editor has something similar?
You mentioned in your comments that you were using Eclipse - normally eclipse keeps a local history of changes that you were and have been making. The following steps may help in that regard:
Restoring deleted resources from local history
To restore a deleted Workbench resource with a state from the local history:
In one of the navigation views, select the folder or project into which you want to restore a local history state.
From the resource's pop-up menu, select Restore from Local History.... The Restore From Local History dialog opens showing all files that were previously contained in the selected folder or project and all of their sub-folders.
Check the files that you want to restore
If you don't want to restore just the last state of a file you can select any other state of the file from the Local History list on the right hand side of the dialog. The bottom pane of the dialog shows the contents of the state.
If you are done with all files click Restore.
Tip: You can configure your Workbench preferences to specify how many days to keep files, or how many entries per file you want to keep, or the maximum file size for files to be kept with the command link General > Workspace > Local History preference page.

I wanted to unstage files (as my .gitignore was not set up to ignore some of my IDE files) but in hurry did :
git add w3
//got some .settings etc folder and files added, in newly added sub folder w3
//the repo here already had sub folders w1 & w2.
Then issued:
git rm -f w3/*
I'm on windows 8. The files are hard deleted (not in the recycle bin). Any thing I can do with git or any other (free) way?
Edit Add
* Also it was opened in STS(eclipse) but now deleted the pom, settings everything. Anyway to restore from within eclipse?
Un-commited but added files are still in a repository for a while, however it would be quite tricky to restore it especially for a large old repository as usually it has a lot of garbage. So, if you don't mind dig into garbage, start with git fsck and look for dangling blob.
However, seems you cannot restore names of lost files, only content.
If the file was not versioned you can't restore it. See the documentation of git-rm. See here for how to undo adding a file to the staging area.
If the file was versioned you can retrieve it from a past commit. See this answer for more information.
Of course if you back up your drive you might be able to restore it with your back up program. For that you might get help over at SuperUser.
I am using Perforce 2015 client (P4V) on Windows 7.
I changed some files in my IDE. Then I use "Folder Diff" in Perforce to locate them. I was expecting to find "checkout" right click menu on the "Folder Diff" Perforce window in order to move my changes to a changeset but I don't see any "checkout" around.
How can I checkout directly from Diff view?
If you changed files on your workstation, but Perforce doesn't know about those changes yet, the command you're looking for is "reconcile".
I believe that P4V's Folder Diff may only show you the reconcile options if you use Folder Diff from the Advanced Reconcile Options variant of Reconcile Offline Work.
So to perform this style of Folder Diff within P4V, you should start by context-clicking on the root folder in your tree view and choosing "Reconcile Offline Work", then choose the Advanced Reconcile button at the bottom of that display, as described here: http://www.perforce.com/perforce/doc.current/manuals/p4v/Offline.html
Then, when Advanced Reconcile opens up the Folder Diff, you will see suggestions in red lettering about what your options are for each file (Mark For Edit, Get Revision, ec.). You can then pick one of those options by context-clicking that file in Folder Diff.
Alternatively (and perhaps more useful, once you get used to it), you can do this from the command line. If you haven't worked directly with the command line before, you can context-click "Open Command Window Here" on the root folder of your workspace treeview to get to the command window. Then, type
p4 status
to see a report about what changes you have made to your files, and
p4 reconcile
to make those files open for add, edit, or delete, as appropriate. Then close the command window and refresh P4V to see them.
I am not sure what your exact scenario and IDE is. I am using Visual Studio with the Perforce plugin, and when I make any changes in my source this plugin will check-out this file automatically (you can also choose to be prompted). So no need for folder diffs to locate any changes.
Should your IDE miss any integration plugin's then a very simple workflow could be like this:
Go to Perforce and check out all the files in your solution
Make your edits in your IDE (online or offline doesn't really matter)
In Perforce choose 'Revert Unchanged Files' on the changelist
And voila, only the changed files will be left in your changelist, you can then review the changes and submit to the depot.
NB: should in the mean time another developer have made any changes to any of your changed files, Perforce will warn you that you need to execute a Get Latest and then Resolve (i.e. merge) the changes.
Decided to take the jump from CVS to SVN.
I setup a new repository in subclipse for my project. When I go to 'Finish' the setup it wants to do an initial commit and presents me with a flat list of files to select the files for version controlling.
The problem is I have thousands of generated binary files I dont want to commit.
So I click on cancel because it would take me all day to go through and unselect all the unwanted files. Annoyingly when I click on a parent category for the files I want to ignore it is not recursive!
So I click cancel then go to the eclipse directory structure for the project and manually set svn:ignore on all directories I want to ignore. Then I try and do a commit again and all the files are once again presented - ignore seems to have done nothing.
Can anybody point out what I might be doing wrong?
For the first commit, I recommend writing a small script to delete (of course you'll have a backup) all the files that are not meant to be committed.
Afterwards, if you find you accidentally committed a file, you can
svn delete file
Upon the first checkout, copy back (or better yet, regenerate) all the binary files. This will trigger svn to notice that your local repository is out-of-sync with the remote repository.
cd <Root of local repository>
svn status
You will see lots of "to be added" items. Go to the parent directory and add in svn:ignore properties for each of the generated items.
cd build
svn propedit svn:ignore .
which will open an editor (if it doesn't, you need to set the environmental variable SVN_EDITOR to a suitable editor). Then you can add in entries that svn will know are not tracked.
(in the ignore property editor)
target
build
image*
*.o
(and so on)
Save the file, and it will be staged for the next commit. Subsequent runs of svn status will no longer show these files as "needing to be added", but they will show the directory as "needing to be committed (it's a revision on the directory)"
Quick Aside
So I'm not entirely certain exactly which functionality of Subclipse you were using in order to create a repo and share a project to it, I'm assuming you created like a file based repo through the eclipse SVN repo view and tried to share and then commit to it. It looks like your problem got solved but I did want to add an answer on here because I ran across this post looking for the answer to this same problem of handling initial commits even just in general with SVN and wanted to offer help to anyone else looking for the help.
Intro
To start off I would recommend not working through an IDE extension like this just for the initial commit as they can miss a lot of the options for handling opening a repo in SVN. I personally really like the command line form of SVN to work with but TortoiseSVN is a good option for a GUI.
Whether you create a local file-based repo or are connecting to an SVN server and you want better control over your first commit in an previously unversioned project here is what I've found as the best general workflow for doing so.
Create the remote folder to save to.
On command line this will be:
$> svn mkdir your-url-scheme://your-site-address.domain/path/to/repo/example-directory
Or on TortoiseSVN open your repo for browsing, right click, and select "create new folder"
This will give you a location in the SVN repo to checkout from for our next step.
Checkout in to the already started project
Make sure to use the empty, newly created folder in your repo to checkout with. SVN does not actually require a folder being checked out to to be empty, which is an important part of what makes it actually very flexible and able to subsume parts of your directory into it fairly easily if used correctly.
Now you will checkout this empty folder into the root folder of your already started project. This will add your project to the working copy of this folder without any commit being made yet. The command is:
$> svn co your-url-scheme://your-site-address.domain/path/to/repo/example-directory /your/projects/root/
"co" standing for checkout. In Tortoise svn you can right click on or in the empty repo folder and select "checkout..." and then select the project root.
Set ignores and commit
Finally, you can easily set your ignores on certain files before adding any other files to the tree using the command:
$> svn propset svn:ignore file-or-directory-to-ignore
And to add all non-ignored directories and files:
$> svn add * --force
The force is technically unnecessary in this case but ensures full recursion. You can also now do all of this in your file explorer if using TortoiseSVN or you can even use your IDE extensions to do this at this point(make sure to ignore all files you need to before mass-adding files for commit), all that's left is to make sure to commit the newly added files to the repo and you're up and running with source control :)
Added this method here simply because this method allows you to avoid any unnecessary copying of those stinky binaries that no one wants to lug around with them.
I deleted a bunch of files from my env and committed the changes.
Of course I now want one of them back.
What is the best way to bring the ONE file back out of the revision?
I have brought the file up from View History on the package (it is a java file), but don't see a way to bring it back short of copy and paste.
Eclipse 3.7.0, subclipse 1.6
UPDATE
It looks like Antonio Pérez and qor72 solutions both accomplish the goal. Antonio's can be done in eclipse but the number of reverts can be large. Also merge requests that one commit open changes.
I like qor72's solution. To access copy in this scenario:
look at the history and find the deleted file.
right click on file name and choose copy.
select the original directory.
OK.
What I have done in the past is ressurrect the file per the SVN documentation, for example:
$ svn copy ^/calc/trunk/real.c#807 ./real.c
Then readd/commit and off you go.
Probably the subclipse client would allow a simple way of doing it. But if you'd like to give a try to the command line client.
$ cd <working_copy_path>
$ svn merge repo_url[#M] repo_url[#M-1]
M is the revision where you committed the deleted files. And you should get back all the files you deleted as added files in your working copy. Then
$ svn commit <your_file_to_be_recovered>
$ svn revert (to remove the rest of added file that you don't need back)
Further info on the svn merge command.
you can follow these steps to get it back
1. Identify the folder in the project which contained the deleted files.
2. Right click the folder, select Team -> Merge
Within Merge Pop up Window
3. On the URL tab, Browse and select the "repository resource to merge with" i.e the same folder in the repository.
4. Select Revisions radio button,
5. Click Browse button to select revisions.
6. Select the revisions which you want to be restored ( select the revision wherein you deleted the files / folders )
7. Enable Reversed merge.
8. Click Preview and check that it shows an entry for the file / folder which you plan to restore.
9. Click OK
10. Eclipse now switches to SVN Merge and with the Synchronize view.
11. In the Synchronize view, right click the files you want and select Accept
12. In the Synchronize view, use the Synchronize SVN icon to switch from SVN Merge to SVN, where you can see the restored file as an outgoing change.
13. Right click the file -> Team -> commit to check in the file again to the repository.
Please note: This is a question about the Eclipse plugin Subversive, and not about Subversion itself. Please do not change the title to be about 'Subversion'.
So I deleted a file that I really shouldn't have.
I've found various approaches to restoring the file outside of Eclipse/Subversive, but I was wondering if there was a best/easiest-to-use/history-restoring way to restore the file using the Subversive tool.
Select the folder in the project that contained the deleted files.
Right click, select Team > Merge...
On the URL tab, set the URL to the server URL for the same folder.
In Revisions, select Revisions and enter a range that includes the deletion, e.g. 1000-1001, or use the Browse button to select them.
In Revisions, enable Reversed merge
Click Preview and check that it shows an Added entry for the files you plan to restore.
Click OK - Eclipse switches to SVN Merge in the Synchronize view.
In the Synchronize view, right click the files you want and select Accept
In the Synchronize view, use the Synchronize SVN icon to switch from SVN Merge to SVN, where you can see the restored file as an outgoing change.
If you have already submitted the remove then it's now time to roll back to the earlier version. In Subversion you do that with "svn merge", where you merge "backwards" from the current to the previous version.
Say you did this:
$ svn rm file.txt
$ svn ci -m "don't need that file"
Committed revision 1325.
Now you want to undo this and restore the old revision 1324, i.e. the state just before the remove (the dot is for 'current directory'):
$ svn merge -r1325:1324 .
If you are unsure you can do a dry-run first, where svn will print the output of the command, but not actually do anything:
$ svn --dry-run merge -r1325:1324 .
The result should indicate that the file is being added (again):
A file.txt
you could switch to revision where this file was exist. Edit/copy this file and switch back to the head revison and commit it here.
Also you could merge changes beetween two revisons - head and last revision file was exist in repository and apply changes to your working copy.
Just "Show History" on the folder, file was existing in. Then click through the history and find the lost file.
I guess you're hoping to not resort to the command line but in case it's useful as a last resort, see this question for how to do it from the command line: What's a simple way to undelete a file in subversion?
Easier: try to commit, Eclipse will show you the dialog with the changed files, click on the one you want to delete with the right button and pick "Revert".
I had a similar issue, I deleted a set of files related to a feature that after a couple of months I want to recover.
The most straightforward solution in my case was to check out in a separate directory the whole project as it was before the file were deleted.
To do this from the Eclipse Repository View go to your project, right click "Check Out As...", in the modal window write the destination folder, select a suitable date of the past in which the deleted file existed (weird, my plugin does not give the possibility to choose a given revision..) and check out.
Now you can easily search, find and copy-paste the files you want to recover.
