I have been dying to solve this problem... but I haven't been able to find a good answer yet.
I was wondering if any of you guys have a better idea for copying files over to other stream under my situation.
So here it goes.
currently, my tree somewhat looks like this.
//My_Depot/My_Stream/UE4/Client/...
//My_Depot/My_Stream/UE4/Client/Binaries/...
//My_Depot/My_Stream/UE4/Client/Config/...
//My_Depot/My_Stream/UE4/Client/Patches/...
//My_Depot/My_Stream/UE4/Client/Tools/...
//My_Depot/My_Stream/UE4/Server/...
//My_Depot/My_Stream/UE4/Admin/...
//My_Depot/My_Stream/UE4/Web/...
I want to be able to p4 copy all directories under UE4 (//My_Depot/My_Stream/UE4)
EXCEPT Patches (//My_Depot/My_Stream/UE4/Client/Patches/...) directory.
How do i go about doing this?
I need Patch directory during build and stuff so can't really exclude them from the view
(or can editing view done dynamically..?)
please helpp
I tried to google, I tried to stackoverflow. but no one really stumbled on my question.
It depends. Do you just want to do this just once? Just open everything for copy and then revert the Patches directory before you submit:
p4 copy
p4 revert UE4/Client/Patches/...
Do you want to skip the Patches directory in your stream every time you do a merge or copy from the parent? Then you want to isolate that path in your stream:
Stream: //My_Depot/My_Stream
Paths:
share ...
isolate UE4/Client/Patches/...
Do you want to isolate it in a particular workspace but not in every workspace of that stream? See above, but make a separate virtual stream with the isolate line in it, and base your workspace on that stream.

I'm very well aware of how to create new folders and move single files between folders. Just edit the name and commit the change.
I was wondering if there was an easy or similar way to move an entire folder to a new location within the same repository.
E.g., say I have myrepo/a/b/c/d/ and myrepo/a/b/c/e/ (that is, /d/ and /e/ are subfolders of /c/), how can i move folder /d/ to be within /b/ (i.e. on the same tier as /c/)?
The end result would be myrepo/a/b/c/e/ and myrepo/a/b/d/.
I'm unfamiliar with the GitHub command line 'thingy' and I would appreciate it if the quick and easy solution didn't use that advanced feature (although I would be glad to learn it).
Don't mark me as a duplicate when I say I have the same question as How to rename a directory/folder in Github(Web)?. It is the very same question, but that question hasn't been answered yet either, or at least the solution isn't clear. Again, I don't need to know how to move a file. I want to move an entire folder.
I have a branch on Perforce, where I changes the directory structure of the project using Rename/Move command.
During merging back to the mainstream, Something went wrong that caused Perforce to think of the new structure as a whole-new directories.
Subsequently, the history of the files in the new directory structure is totally unrelated to the history of the same files before changing the structure.
Is there anyway to recover this situation ? Or ask Perforce to append the old history with the new history ?
Something went wrong that caused Perforce to think of the new structure as a whole-new directories.
Usually if this happens it means someone didn't use the "rename/move" command and used some other method to rename instead (i.e. they did something that adds the new directory as a new set of files independent of the originals rather than an atomic rename of an existing set of files). It's impossible for me to say how to "recover" without seeing what the history of the files looks like now so I can reverse-engineer what the "something went wrong" was.
I'd recommend either posting on the Perforce forums or contacting Perforce technical support so that somebody with expertise can wheedle the necessary data out of you (I can intuit that this will require an amount of back and forth that stackoverflow frowns on -- "what were the branches you were merging from and to", "okay, now run THIS command to see the history of that branch and send me the output," "okay, which of these five merge operations I can see in the history is the one you're talking about,") and propose a solution.
From another answer:
So, for a file a/b/c, you can look at the by using the -i option where appropriate. For example, p4 filelog -li a/b/c.
This is not necessary if files are renamed via the "move/rename" command, so if you need to use "filelog -i" to see file history, the files were definitely renamed by some other method. (The "p4 move" command was added in 2009 so long-time Perforce users will sometimes use other workflows.)
I need to replace a library in a perforce depot. The library is checked in in the form of source files which are all managed by perforce.
Now the problem is that in the new version of the library there may be
unchanged files
changed files
new files and
some files may have been deleted
Of course I can just mark the whole source tree for delete, submit, copy the new version of the library to the directory in question, mark for add and submit again, but that would create a short interval of time in which no one should synchronize in order to not break his next build -- maybe that's the best option but I'd like to know whether there is a better approach.
A second solution is to copy the new version of the library to some other directory, update all references in order to reflect the new location, and then just delete the old library and mark the new one for add. This can be done in one change list. The unpleasant and error prone part here is to update the references. Also a change in the directory names is not really desired.
Does anyone know a way to do this in one step with one changelist? I experimented with a single file example. It actually is possible to mark a file for delete and then immediately create a file with the same name and mark that for add. If you do that and submit, then the result is exactly what I want for that single file. This procedure, however, seems to require touching each file manually. I could not figure out how to do that for a whole directory or directory tree.
One possibility is to use p4 reconcile to do the majority of the work, using a process such as:
In your workspace, remove the current copy of the source tree entirely: rm -rf top-directory-name (or del /s /q if you're on Windows).
copy the entire new copy of the source tree for the library into that location.
Run p4 reconcile and let it figure out what files to open for add, for edit, and for delete. CAREFULLY inspect the results by looking closely at p4 opened, p4 diff, etc.
Submit the new changelist.
I am doing a refactoring of my C++ project containing many source files.
The current refactoring step includes joining two files (say, x.cpp and y.cpp) into a bigger one (say, xy.cpp) with some code being thrown out, and some more code added to it.
I would like to tell my version control system (Perforce, in my case) that the resulting file is based on two previous files, so in future, when i look at the revision history of xy.cpp, i also see all the changes ever done to x.cpp and y.cpp.
Perforce supports renaming files, so if y.cpp didn't exist i would know exactly what to do. Perforce also supports merging, so if i had 2 different versions of xy.cpp it could create one version from it. From this, i figure out that joining two different files is possible (not sure about it); however, i searched through some documentation on Perforce and other source control systems and didn't find anything useful.
Is what i am trying to do possible at all?
Does it have a conventional name (searching the documentation on "merging" or "joining" was unsuccessful)?
You could try integrating with baseless merges (-i on the command line). If I understand the documentation correctly (and I've never used it myself), this will force the integration of two files. You would then need to resolve the integration however you choose, resulting in something close to the file you are envisioning.
After doing this, I assume the Perforce history would show the integration from the unrelated file in it's integration history, allowing you to track back to that file when desired.
I don't think it can be done in a classic VCS.
Those versioning systems come in two flavors (slide 50+ of Getting git by Scott Chacon):
delta-based history: you take one file, and record its delta. In this case, the unit being the file, you cannot associate its history with another file.
DAG-based history: you take one content and record its patches. In this case, the file itself can vary (it can be renamed/moved at will), and it can be the result of two other contents (so it is close of what you want)... but still within the history of one file (the contents coming from different branches of its DAG).
The easy part would be this:
p4 edit x.cpp y.cpp
p4 move x.cpp xy.cpp
p4 move y.cpp xy.cpp
Then the tricky part becomes resolving the move of y.cpp and doing your refactoring. But this will tell Perforce that the files are combined.
Is there any way to have the same file be a part of multiples changelists in perforce? With that I mean that from the set of changed lines in the file one subset will belong to a changelist, while the other subset will belong to a second changelist.
Bonus question: If perforce does not support this, then which Source Control Systems, if any, do?
To answer the bonus question: GIT allows for per-line changelists.
For a comparison between the two view this question: GIT vs. Perforce- Two VCS will enter... one will leave.
The same copy of the file? No, unfortunately this isn't possible.
Another way to do this without branching is create additional workspaces (clients). Unless you really know what you're doing, be sure to set a different root directory in each of your workspaces. To save time (and disk), don't bother syncing the whole depot in the new workspace.
Sometimes, I'll have two copies of a depot (using two workspaces); one which contains work-in-progress and one which I keep unmodified. If I need to make a quickie change on a file that's heavily modified in my WIP workspace, I can use the 'virgin' workspace to make the change and submit it.
If you are using p4 server 2009.2, there is a workaround to do it. You can shelve a particular file and the diff is stored on the server. After shelving you may want to revert the file to its original version and then work it on in another change-list.
I know this is not a way you wanted it but it is quite easy to create another workspace/client and then sync the code. The later exercise becomes more tedious when you have volumes of code that goes into another application.

You could make a copy of the file with all of the changes, revert, edit the file copy one set of changes into the file, submit, edit, copy the next set of changes, submit, edit, etc...
Bonus answer: I found this feature in Rational Team Concert (http://www-03.ibm.com/software/products/en/rtc/). You can have the same file in many changesets. If you want to add File1 to Changeset1 and Changeset2, you must complete Changeset1 first. This allows you to add File 2 to Changeset2 but then a dependency between changesets is created, so you can not deliver Changeset2 without delivering Changeset1 too. Moreover you can not make changes to a complete changeset.
