sync two vobs file (by clearfsimport) without checking in the updated file - linux

I am using following command to sync B vob files from A vob
clearfsimport -master -follow -nsetevent -comment $2 /vobs/A/xxx/*.h /vobs/B/xxx/
It works fine. But it will check in all the changes automatically. Is there a way to do the same task but leave the update files in a check out status?
I want to update the file for B from A. Build my programme, and then re-cover the branch. So if the updated files is an check out status, I can do unco later. Well with my command before, everything is checked in. I cann't re-cover my branch then.
Thanks.
As VonC said, it's impossible to prevent "clearfsimport" to do the check in. And he suggested to use a label to recover back.
For me, the branch where I did "clearfsimport" is branched from a label.Let's call it LABEL_01. So I guess I can use that label for recovery. Is there an easy way (one command) to recover the files under /vobs/B/xxx/ to label LABEL_01 ? I want to do it in my bash script, so the less/easy the command is, the better.
Thanks.

After having a look at the man page for clearfsimport, no, it isn't possible to prevent the checkins.
I would set a label before the clearfsimport, and modify the config spec for the new version to be created in a branch (similar to this config spec).
That way, "re-cover" the initial branch would be easy: none of the new version would have been created in it.

Checking out to another commit with git while reading the file

I am creating a server that handles version control of files in server and let the client view them at specific commit if they wanted.
The way I implement this is that when user clicks a specific commit, I call checkout [hash of commit] to revert the file back to what it was and then read from that file.
The problem is that two people may be trying to read different commits of the same repository at the same time, meaning the state of file may change while reading from the file.
I tried checking out another commit while reading from it and it seems to work okay but I cannot be sure when the it is scaled.
I am using nodeJS and express for my server. When nodeJS starts reading file, will it still be the same state as the point when it started reading or would it change along with the change that is forced by git if I checkout another commit while reading the file?
Instead of using checkout, consider show:
git show <commit id>:<filename>
This will print the contents of the file at that commit. If you absolutely need it in a file, generate a unique temporary filename and redirect the output:
git show <commit id>:<filename> > tmpfile_uniquesuffix

PTC Integrity batch update member revision

Is there a way to update the member revision of a big list of files via command line?
I can't use :working or :head but have to specify a different revision for each file.
As far as I know --selectionFile only takes paths as input, but not the revision numbers.
edit: I wanted to set member a very big list of files and I wanted to avoid writing the command si updaterevision ... for every file, as it takes ages to complete for that many files. Instead I wanted to know if there is a more advanced method to specify a list of files and their revisions to be able to run the updaterevision only once (like it is with :working) for the whole list of files.
But as it is said in the comment there is no such possibility.
edit2: I use MKS for a couple of years now and as I now know, there is no such possibility (at least up to MKS 11.6) to update many files to different revisions with one single command line call. But using one call per member, as was proposed, made the whole operation take up to several hours as I had many thousands of members in the sandbox and MKS needs some time to complete each sicommand.
Some time already passed since you asked for this question, here is my comment in case it could still be useful for you in the future.
First, It is not completely clear what you want to achieve. Please be more descriptive and if possible provide example.
What I understand as of now is you need to set bunch of files listed as member revision thru the command line. This is fairly simple, the most complicated is actually to have the list of files to be updated to member and the revision that you want to set as member.
I recommend you to create a batch file with the commands to make each file member. You can use Regex to do it very quick and without much trouble.
Here is an example for updating one file member revision:
si updaterevision --hostname=servername --port=portnumber --user=username --changepackageid=5873763:2 --revision=:working myfile_a1.c
where
servername = the name of the server where your sandbox is located
portnumber = the port that provides access to the server for your sandbox
username = your login user id
changepackageid = here you change the number to use your defined TASK:ChangePackage for this changes
revision = if you have a working revision that you want now to become member, just use "working" as revision, otherwise you can define specific revision number, e.g. revision=1.2
At the end you define the name of the file you want to update.
Go to you sandbox root folder, open CMD window, and run the batch file. It will execute each line applying your changes.
If you have a list of files with the revision you want as member, you can use REGEX to convert it into a batch file.
Example list of files in text file:
file1.c 1.10
file3.c 1.19
sec_file1.c 1.1.2.1
support.h 1.7
Use notepad++ or other text editor with regex support and run this search:
Once you know which regex apply, you can now use it in the notepad++ to do a simple search and replace:
Search = ([\w].[\D])\s+([\d.]+).*
Replace = si updaterevision --hostname=servername --port=portnum --user=userid --changepackageid=6123933:4 --revision=\2 \1
\1 => FileName
\2 => File revision
See image below as example:
Finally just save doc as batch file and run it.
Just speculating that if you have a large list of members along with the member revision you want to update to, then you also have an sandbox that served you to generate this list.
If so my approach would be
c:\MySandbox> si updaterevision --recurse --revision=:working
If your member/revision list come from a development path you could first have a sandbox targeting that devpath, resync, (close thesandbox if opened in gui), retarget the sandbox to the destination devpath (or mainline) you want and then issue the command above.
For an single member approach I would use 'si rlog' to generate a list of si-commands directly
si rlog -R --noheaderformat --notrailerformat --revision=:working --format="si updaterevision {membername} --revision={revision}\r\n" > updaterevs.bat.txt
Review updaterevs.bat.txt rename it to updaterevs.bat and ecxecute it.
(Be careful if using it on other sandboxes)
Other interesting readings here might be the "snapshot sandbox" feature,
checkpointing in general and variants rsp. devpaths.
Using only these features might be politically more correct in the philosophy of Integrity.

Layering projects on top of each other with git

Let there be:
There are different repositories repoA, repoB and repoC each respecting the same directory layout principles, which are to be merged onto a third repoM's working directory (the "master" project).
repoM has an atypical setup (--work-dir and --git-dir are sepparate). repo[A-C] are cloned as bare, and they are set as core.bare = false and core.worktree=<--work-dir-of-repoM>.
The requirements:
I need to always have an overview over the history of all files in repoM's work-dir, which could have stemmed from repo[A-C]. With this approach, I lose all that information.
Alternative:
I've been thinking about using git-subtree instead (git version 1.7.11.2, so it's already built-in), leaving repo[A-C] bare, and then
git pull -s subtree, or
git subtree ...
With the subtree pull strategy, I lose the history on a merge conflict (git blame says so).
I've never used subtree before, but from my understanding it's not possible to merge files from repo[A-C] into repoM's work-dir, those files must be put into a subdirectory of repo[A-C]. This is definitely not what I need. Why? Because of the following ...
Problem statement:
You have different git repositories each containing different sets of files, usually configuration files and some shell scripts. You want to put everything in the $HOME (which is <--work-dir-of-repoM>) directory from all those repositories. You should be able to see at all time where each file comes from, edit, commit and push changes to each one's origin. You've guessed it, it something like vundle, but generalized for any kind of configuration of any program, not just vim bundles. If a conflict occures, one should be able to track down which two authors of the same file need to get in touch with each other and make up a deal (if one needs to be made).
This is for an open-source project I'm trying to get a prototype working, so any help is highly appreciated. Also ideas about already existing projects which do this in a similar manner are highly appreciated.
Note: the "master directory" does not necessarily have to be $HOME, I've used it as a possible hint on the kind of problem this could solve.
Why not simply use Git Submodules in your "master project"?

svn clear projects with all revisions

is there a commend to delete project from svn with all its revisions(total cleanup) ?
cheers
The answer is in the Subversion FAQ:
There are special cases where you
might want to destroy all evidence of
a file or commit. (Perhaps somebody
accidentally committed a confidential
document.) This isn't so easy, because
Subversion is deliberately designed to
never lose information. Revisions are
immutable trees which build upon one
another. Removing a revision from
history would cause a domino effect,
creating chaos in all subsequent
revisions and possibly invalidating
all working copies.
The project has plans, however, to
someday implement an svnadmin
obliterate command which would
accomplish the task of permanently
deleting information. (See issue 516.)
In the meantime, your only recourse is
to svnadmin dump your repository, then
pipe the dumpfile through
svndumpfilter (excluding the bad path)
into an svnadmin load command. See
chapter 5 of the Subversion book for
details about this.
No, I don't believe there is.
If you really need to remove files completely from SVN history, I think the only way to do it would be to do something like dumping the repository, filtering out the files you don't want with svndumpfilter, and then recreate the repository from the dump.
Why do you want to do this?
rm -rf on the repository usually works fine.
this is how to do this on Linux:
/>svnadmin dump /path/to/repos > proj.dump
/>cat proj.dump | svndumpfilter exclude somefolder > cleanproj.dump
/>service svn stop
/>BACKUP /path/to/repos/conf /path/to/repos/hooks (all custom configuration for this repository)
/>DELETE /path/to/repos
/>svnadmin create /path/to/repos
/>RESTORE /path/to/repos/conf /path/to/repos/hooks
/>svnadmin load /path/to/repos < cleanproj.dump
/>service svn start
done
I'm assuming that you are talking about multiple projects under the same repository:
myrepo/
project1/
project2/
If you simply want a project to 'disappear' without screwing with the repository history, you can simply hide this path if you are using an authentication mechanism that utilizes authz. In other words, you are not using 'svn+ssh' to access the repository.
Let's say I already have a group in my authz called 'everyone'. The in my authz I will set something like:
[/project1]:
#everyone =

CruiseControl.Net Deleted Files

I'm using CC.net on against a Source Safe database, and have a problem that someone deleted some files from the database, and the deleted files weren't removed. I didn't see a config switch or anything that I could set for it to clear the code directory prior to building.
Am I missing something?
As Alex says there is a CleanCopy flag in the source code block. However, my situation was a little different. I use subversion and I found the CleanCopy flag was NOT doing what it said it would on the box.
To solve the problem I added a task which runs a batch file that clears out the build's working copy prior to checkout. It is a bit slower (about 1 min for code base of 400Mb) but guarantees no old code.
Kindness,
Dan
All you need to do is set CleanCopy to true in your source control block. The documentation is very clear on this. The above answer is the wrong way.
