In Clearcase, how do I resolve "loaded but missing" for an element in my snapshot view?
The last thing I did was to delete a branch, for which my config spec was currently using a rule to see.
I've tried deleting the file(rm filename), and updating my snapshot view again, to no avail
Figured it out: I followed the instructions here.
Removed the file(rm file.cpp).
'cleartool get -to /path/to/snapshot/view/file.cpp file##/main/myBranch/LATEST'
Next, the file was hijacked, so I did a cleartool update but specified to "Rename hijacked files and load selected version from the VOB" as instructed in the instructions here,

Is there anyone who knows a way to find all added files in a CCE view? just to verify that no file is missing before applying label.
thank you.
No file missing means some files might be still in checkout mode, but even then, applying a label would be applied on that checkout version (you would need to make sure and checkin them later)
You can list files still in checkout here.
A better query would be to list all files with versions more recent than the previous label (assuming base ClearCase here, not UCM)
You can use the date for instance to list all files with version newer than a date
ct find -all -type f -version "{created_since(11-apr-2013) && brtype(branch_name)}" -print
That way, you will know all added files, and can check if there are any missing before applying a label.
The OP Frimus proposes an alternative solution in the comments:
I resolved the issue by creating an other view with the same config spec,
and I compare the two views.
I'm new to CC and I'm coming from Git and Mercurial background, probably thats why ClearCase confused me so much. I've been assigned a task to migrate latest CC's revisions to Git. Problem is that I couldn't manage to checkout any branch other than main in CC.
I have a view that displays all VOB's /main/LATEST revision. I assume, main branch's latest revision.
element * CHECKEDOUT
element * /main/LATEST
Now I need to get the list of other branches in a particular VOB. To do that, I navigate from terminal in that folder and run
cleartool lstype -kind brtype -invob /%VOB_NAME%
and I can see the list of branches. Correct me if I'm wrong, but I assume, it displays only the branches relevant to VOB(%VOB_NAME%).
Now I need to checkout the branches. What is the standard way of doing this. I tried updating config spec with something like:
element * /%VOB_NAME%/%BRANCH_NAME%/LATEST but it doesn't seem to work.
Pretty sure I'm not doing it correctly.
Also for migration purpose, I'll need to automate the steps to acquire branches and checkout the branches. I guess updating config spec to switch branch in a view takes some time and probably is an async operation, so is there a way to determine when view finishes updating?
Or maybe there's command line option to switch branch for a particular VOB in a view?
So in short, here's my questions I'm struggling with:
Than
Am I acquiring VOB branches correctly?
How can I checkout a particular branch?
Is there a way to determine when checkout finishes?
thanks
UPDATE
ok I tried #VonC's recommendation so my config spec looks like this:
element * CHECKEDOUT
element * .../heine_1/LATEST
element * /main/LATEST
If I'm guessing correctly, one VOB containing branch named heine_1 should checkout that particular branch, the rest of VOBs will stay on main branch, but this is not the case. When I run cleartool ls inside that VOB, its still on main branch. All folders are postfixed with Rule: /main/LATEST. So I guess it didn't switch the branch.
Thanks
There are a few questions in the original question and the comments.
Addressing the configspec issue first...
The syntax of an element rule is:
element {path} {version rule} {optional clauses}
If you need a VOB-specific rule, you can do something like this:
element \myvob\... ...\myvobbranch\LATEST
element \myvob\... \main\LATEST -mkbranch myvobbranch
The "..." in the path means "this location and everything underneath it."
The "..." in the "version rule" means that the branch name is at the end, so this would match /main/myvobbranch/LATEST, /main/br1/myvobbranch/LATEST, etc.
If you're working on a branch, you generally want new files or work to appear on the branch you are working in, and the second line makes that happen.
Everything in a configspec is case sensitive, so be aware that "LATEST" is not "latest."
Since the view was created for you, I'm reasonably certain that it is a dynamic view. If it is mapped to a drive, it's definitely dynamic. If you need to know for sure, you can CD into the "working area" of your view and run "cleartool lsview -pro -full -cview" and look at the "attributes" line. The line for a dynamic view will look like this:
Properties: dynamic readwrite shareable_dos
On the direct questions:
Yes, you are acquiring the branch list correctly.
By default the checkout is done using the version selected by the view, you can use cleartool checkout -branch {full branch path} {file name} to check out the latest on a branch, or cleartool checkout -version {version id} {file name} to check out a version other than the latest on a branch. I would not recommend either as a normal practice. The -branch will cause checkins to go to the element's parent branch. The -version would require add a requirement to perform a merge to get the checkin to complete, which would also go to the version's parent branch.
Checkout is finished when the command finishes.
A big "new user gotcha" is that directories are also versioned objects. If you're adding files to source control, you need to remember to check the directory in so that they are visible by others with similarly configured views. The ClearCase GUIs have this behavior as a default if you started the process with the directory NOT checked out, but not if you explicitly checked out the directory beforehand.
I have a file in lost+found which is checkedout but I do not see any viewreference. How can i remove the file?
I'm Checking in windows system. When I do a version tree, I see a view that was created in some unix system. I'm not able to get the uuid of the same.
How can I delete such file?
For the checked out state, You should be able to get the view uuid in the same way as in the previous question "How do I delete check-outs from a particular view in clearcase?".
That lost+found folder is part of a vob and a cleartool describe -b vob:\Avob should list the uuid of the unix view.
But if you are not sure which uuid matches the actual name of the old view you see in the version tree, you can check for that name directly in the registry server.
There are different option:
cleartool rgy_check -views
But also, since I have access to the registry server, I can do a simple grep of the name in the var/rgy folder where view_tag is:
<user>#<server> /path/to/ClearCase/var/rgy
$ grep -i <view_name> view_*
view_object:-entry=view_object;-hostname=server;-local_path=path/to/<view_name>.vws;-owner=<name>;-view_uuid=e670fe8a.fb0540e5.83f4.7f:82:a6:s8:e1:1a;-attributes=sumview;
view_tag:-entry=view_tag;-tag=<view_name>;-title=<title_View>;-hostname=server;-global_path=\\server\views\path\to\<view_name>.vws;-region=<region>;-view_uuid=e670fe8a.fb0540e5.83f4.7f:82:a6:s8:e1:1a;
That way, from then name, you get back the uuid and can remove the checked out state from the vob.
Regarding the file itself (in lost+found), see technote "About the lost+found directory", that I mentioned in "How do I retrieve a file if I undid a folder checkout in ClearCase?".
There are two possible ways to remove an object from the root of the lost+found:
The object can be moved to a new location in the VOB using the cleartool mv command
The object can be permanently deleted from the VOB.
Be careful with the second option (which involves rmelem), especially in UCM (where that object could have in previous versions baseline labels attached to them)
I have a static view with some files checked out that I am working on. Someone else checks in a bunch of changes that I want to add to my view. So, I run update on my view. It turns out they changed a file I have checked out. Now my view is left only partially updated and may not even compile until I figure out which checked out file I have to manually merge.
I know I can reserve my checkouts, but that blocks other devs from checking in stuff they are done with.
According to: http://publib.boulder.ibm.com/infocenter/cchelp/v7r0m1/index.jsp?topic=/com.ibm.rational.clearcase.cc_ref.doc/topics/ct_update.htm
update does not apply to files or directories that are checked out to the current view.
So, it seems it's working as the atria/rational/IBM folk want it to work. I don't understand why it works this way.
Is there any way to update my static view and also automatically merge changes into my checked out files?
Is there any way to update my static view and also automatically merge changes into my checked out files?
Not really, since a checked out file is a file being modified locally, and cleartool update tries very hard to not touch any local file.
Your checked out file is selected by the element * CHECKEDOUT selection rule, which means any update won't update it (it is already selecting the right version).
You need to check in those file (triggering the merge, similar to "To merge the latest version to a hijacked file"), and check them out again.
But that isn't always possible since it would make a work in progress visible (checked in) to other views in the same branch.
The only other solution is to compute a patch between the checked in version and your checked out file, and apply that patch cleartool lsco -all -s -cview | xargs cleartool diff -diff, with the difficulty to diff between your checked out version and the LATEST version.
When I execute a "cleartool ls filename##specificVersion", I see
filename [not loaded]
What does this mean?
For background information, I was trying to also execute a cleartool mkbranch, and was a "Element not found" error. So, for a sanity check, I tried a cleartool ls.
"not loaded" means the file:
is selected (by the selection rules element * ...) but:
not loaded by the load rules (load /xx/yy...)
You can see both sets of rules by doing a cleartool catcs anywhere within your view (or cleartool edcs to edit said rules)
This is typical of a snapshot view, which is the only one having "load rules" (as opposed to a dynamic view)
See:
"Before accessing files not loaded into snapshot views":
A snapshot view contains only the set of elements that you specify in the load rules of your view. (In UCM, by default, your view loads all of your project source files.)
When you restrict the scope of a view, it contains only a subset of elements in the VOB. During the course of a development cycle, you may need to see a version of an element that is not loaded into your snapshot view.
You can view nonloaded files or copy them into your view for build purposes, but you cannot check them out. Only file elements that are loaded into your view can be checked out.
"To copy a nonloaded element into a snapshot view"
cleartool get -to filename path
cleartool get -to prog.c.previous.version prog.c##/main/v3.1_fix/10
