Perforce Change List too Big - perforce

In Perforce, I have created a change list that has over 200,000 files (by doing a rename on a directory). This change list is now too big to submit or revert. When I try, I get an error saying that the operation took too long.
I am now stuck with this change list that has my original directory in marked for delete state and a new directory that hasn't been submitted. Is there a way undo this change list?

You can revert the files a few at a time. As a test, you could run p4 revert //path/to/some/file and verify that it's able to revert that file.
Once you know that's working, you just need a way to automate the process.
You could script something up that starts in the root directory and runs through all directories breadth-first, running p4 revert //path/to/folder/* at each folder (I think you could also use client paths).

You can revert via the command line using the p4 tool. I do not think you can revert the files from the UI. The associated documentation shows various examples of how revert all or specific files (see the Examples section):

How can you save and restore a list of checked out files in Perforce?

I have, in perforce, a sort of 'basic working set' of files that I keep checked out (and therefore writable) when working. However, every time I commit my changes, this list gets disrupted - some things committed, others reverted - and then I have to waste time tracking down and checking out all these files again.
So, is there some way to save the list of currently checked out files, and then later check out those same files again?
I primarily use P4V, but I have P4Win and command-line Perforce available. I'd strongly prefer a GUI solution, though.
I only want to save and restore the state of which files are checked out, not the contents of those files, so shelving is not the answer
I am aware of the 'Do not submit unchanged' and 'Check out after submit' options. They are not sufficient. For instance, frequently I will have files which are programmatically generated which register as 'changed' when the only thing that is different is the 'File generated on' timestamp; I need to prevent such spurious revisions from being submitted, and I have not found any practical method of searching for and managing such files that doesn't involve the 'revert if unchanged' command.
You can do:
p4 -ztag opened | grep depotFile | cut -d ' ' -f 3 > files.txt
to save a list of files already open in your client. (If you don't have Unix utilities for Windows, you could construct this list by whatever means you want, such as running p4 opened > files.txt and manually editing files.txt in an editor.)
Once you have a list of files, you can open all of them via:
p4 -x files.txt edit
This doesn't meet your preference for a GUI-based solution, but you could create .cmd scripts to perform these actions and then double-click on them (or on shortcuts to them).
The easiest solution would be to exclude those generated files via your workspace specification, e.g., "-//depot/files/ignorablefile.sh"
They can still reside in your local workspace, but the app will not attempt to update them or add them to source control.
You said that shelving's not the answer, but that's what I would go with as the easiest solution (i.e. the one that involves the least scripting and/or fewest manual steps) for the specific question you're asking:
Shelve your pending change (let's call this change 1000).
Move your open files to a new pending change (let's call this change 1001).
Submit change 1001.
Unshelve change 1000.
Sync and resolve.
Now you have the same exact files open (the unshelve opened them) but at the head revision (the sync and resolve does that).
Now, looking past what you asked for to what might make your life easier: rather than reverting the files you don't want to submit (and having some sort of scheme to get them back later, possibly via shelving as described above), what I'd do is move them to another changelist. So instead of:
Identify "unchanged" files.
Revert unchanged files.
Submit remaining files with "reopen" option.
Reopen previously reverted files (somehow).
I'd do:
Identify "unchanged" files.
Move unchanged files to another changelist N.
Submit remaining files with "reopen" option.
Move all files from changelist N back to the default changelist.
All of those except step 1 are simple one-shot commands that you can do from any client. Personally, I'd automate steps 1+2 with a script (I'm assuming it's programmatically possible to determine whether the only diff in one of these files is the timestamp) and put it into P4Win/P4V as a "custom tool".

Track changes missed by not using "check out and open" a file in perforce

I have a few files that have been edited by an external IDE, I forgot to Check Out the files before making the changes however when I look at the files through P4V the files have changed but the indicator for the file itself shows as nothing has changed. How can I ensure my changes are committed without loosing what I have done?
One way I was thinking was to making a copy of the file, revert, check out, copy content or replace file.
That is OK with a few files but what happens when you have done so with hundreds of files?
The "check out" command doesn't modify the local file, so you can just do that on its own without having to make a backup copy of the file first. (What you want to avoid doing is "get latest", although if the local files are writable, Perforce will automatically balk at updating them by default because of this exact situation.)
If you have lots of files that might or might not have been modified in different ways, use Actions > Reconcile Offline Work, or "p4 reconcile" from the command line. This will find the locally modified files and open them for the appropriate action.
The P4V way to do this is called "Reconcile Offline Work": http://www.perforce.com/perforce/doc.current/manuals/p4v/Offline.html
Or, at the command line, you can use 'p4 reconcile': http://www.perforce.com/perforce/doc.current/manuals/cmdref/p4_reconcile.html

How do I force Perforce to add files to changelist?

I'm a very fresh user of Perfoce, so please be patient!
I am trying to create a commit (I understand it that in Perforce it is called a changelist) of the files which have been changed. It sort of happens automatically in other VC systems, but there seems to be no easy way of doing it in p4... The problem is (maybe) that I'm not editing the files by hand, the files are generated (please don't ask me why do I have to check in the generated files...) so the whole directory tree is getting removed and then copied over with the new files. But Perforce acts as if nothing happened. In both my workspace and the depot it displays the updated files, but when someone will check them out on another machine, the files will be of the previous version.
I'm fine with doing it either through GUI or through the command line. I'd prefer the command line, because that would spare me the trouble in the long run, but it doesn't seem like it should be much hassle either way.
In other words, let's say, this is the workflow I'm used to from SVN or Git:
Run status to see what changed.
Stage / add to commit what you want to be in the next revision.
Commit and send it to the versioning server.
What I'm not able to do is the "stage" phase - because the changes are not discovered automatically.
EDIT
Ah, I think, I figured it out: reconciliation was what I needed... well, I guess if you don't marry, this word would hardly ever happen in your vocabulary :)
It appears that the proper command is reconcile. Also, as Bryan Pendleton suggested there should be status, but I must have an older version of Perforces, which doesn't have this command. This command is also available from context menu in either depot or workspace panels of Perforce graphical interface, when you click on the modified file.

How do I download files from perforce to a location other than a workspace?

I want to get files from Perforce without putting them into a workspace.
E.g.
I have made changes in 2 files.
file1.cs
file2.cs
Now I want to build the project using updated file1.cs, so I want to get latest files except for file1.cs.
I thought I will get another local copy of project and build it.
I'm not sure what you really want to do, but you can get the contents of a file from the depot without using a workspace definition by using "p4 print". Example:
>p4 print -o fileName.cs //depot/path/to/fileName.cs
As far as I am aware you cannot sync files from a Perforce depot without using a workspace since this is the way it tracks what version of files you have in your workspace and also where to put them on your local machine (as well as a few other things).
I'm not sure I entirely understand your problem but if what you need to do is get another copy of the file1.cs you have in the depot without removing the changes you have to it you can simply copy the changes to another location or shelve them and re-sync the file. The more complete and less dangerous solution is to create another workspace pointing to a different physical location on your machine but the same depot location.
This explains how to create a workspace if you need it:
http://www.perforce.com/perforce/doc.062/manuals/boilerplates/quickstart.html
Make sure the 'Root' path is different to that of your current workspace, you can check what your current workspaces root is by going to the workspace tab in P4V and viewing it.
Once you have created the new workspace create a new connection and select it then sync the file(s) you need.
So I want to get latest files except file1.cs
You shouldn't do that; you should update all files and resolve any conflicts with file1.cs
Consider the situation where someone else has made changes to file56.cs that relies on changes also made to file1.cs. If you take their changelist but overwrite (or do not take) their file1.cs, then your build will break.
Shelve file1.cs so you can safely revert your local change:
p4 shelve file1.cs
p4 revert file1.cs
Now you can do your build with whatever version of file1.cs you want (you can sync back to an older version or whatever).
When you're ready to return to your change:
p4 unshelve -s CHANGE
If you're in the UI you can use File->Export To... which will copy the selected file to any folder you want.
I found the workaround but not the solution.
I get another local copy of project then build the project and submit the change.
I found an easy way of doing this with git:
$ git p4 clone //depot/your/folder

In Perforce, can you rename a folder to the same name but cased differently?

Can I rename a folder in Perforce from //depot/FooBar/ to //depot/Foobar/?
I've tried this by renaming from //depot/FooBar/ to //depot/Temp/ to //Depot/Foobar/ but the end result ends up the same as //depot/FooBar/.
Once it is in Perforce, the case remains set. As mentioned by Johan you can obliterate, set the name up correctly, and add it in again. However, there is a slight gotcha....
If anyone else (running Windows) has already synced the wrong-cased version, then when they sync again the right one, it will not change the case on their PC. This is a peculiarity of the Windows file system acknowledging case but still being fundamentally case-independent.
If a number of users have synced, and it is not convenient to get them to remove-from-client too (and blasting the folders from their machines), then you can resort to a dark and dirty Perforce technique called "Checkpoint surgery". It's not for the fainthearted, but you do this:
Stop your server, take a checkpoint.
Using your favourite text editor that can handle multi-megabyte files, search & replace all occurances of the old case name with the new. You could of course use a script too.
Replay your checkpoint file to recreate the Perforce database meta data.
Restart your server.
This will affect all user client specs transparently, and so when they sync they will get the right case as if by magic.
It sounds hairy, but I've had to do it before and as long as you take care, backup, do a trial run etc, then all should be OK.
Maybe not needed anymore, but here's the official Perforce HowTo about changing file cases on Windows and Unix: http://answers.perforce.com/articles/KB/3448/?q=change+file+case
I'm not sure about directories, but we've had this problem with files. To fix it, we have to delete the file, submit that change, then p4 add the file with the correct case and submit the second change. Once that's done, unix users who have sync'ed the incorrect-case file have to p4 sync, then physically delete the file (because p4 won't update the case) and then p4 sync -f the file.
Our server is on Windows, so that might make a difference.
I guess it treats files and folders the same.
For files:
It depends (on whether you have a Windows or Unix server). We have this problem with our Windows perforce server (which versions our Java code), where very occasionally someone will check in a file with a case problem (this then causes compile errors because it's Java). The only way to fix this is to obliterate the file and resubmit it with the correct case.
I think you should remove the Perforce Cache, so that your modification can be shown.
You can rename with ABC rename to abc_TMP, then abc_TMP rename to abc, then clear cache.
Setps to clear cache:
Open windows user home folder (on windows7 ==> C:\Users\)
Locate the folder called ".p4qt"
Rename the folder to "old.p4qt"
Launch Perforce, now everything works!
NOTE: these steps will rest your default setting.
The question is over 3 years old, but I ran into an issue like this while doing a Subversion import into Perforce and figured the info I got could be useful to some. It's similar to the obliterate method, but helps you retain history. You use the duplicate command that may not have been available back then to retain the history. The process basically being:
Duplicate to temporary location.
Obliterate the location you just duplicated.
Duplicate from the temporary location to the renamed case location.
Obliterate the temporary location.
Through this you retain the history of file changes, but get them all in the new path as well. Unfortunately there will be no history of the path case change, but that seems to be unavoidable. Similar to other methods mentioned here, users will need to either manually rename the directories in their workspace or delete and re-sync to get the new path name.
Also, P4V caches the paths it shows in the tree so after doing this it may still show up as the old name. a p4 dirs command however will show the new case.
