Elphel on SourceForge CVS tree description

Actual "stable" tree for NC353L

First of all "stable" have "" because it's CVS, developers may upload code temporary breaking it's compilation or usability.

Under development tree

Elhel CVS and Cervisia (GUI front end to the CVS)

TODO: Not all of the functionality described below applies to the elphel-community project, that should be done It is possible to use Cervisia (unfortunately Konqueror integration as of now is broken in KDE 4.X, so it should be run as a standalone program). After you install the Elphel software using ./install_elphel (either from the source archive or the CVS, manually or using the script) you may get to the top working directory ( by default it is called "elphel353" and has subdirectories starting with "apps") and run 

make update

If you run it for the first time it will create CVS-related directories and files (all directories are called 'CVS'). If you did that for anonymous user (read only access) and later want to upgrade to developer (read/write) access you'll be able to upgrade it as described below. After "make update" you may just open the elphel353 directory in the Cervisia and enjoy using CVS without the need to remember the command line options fro the cvs command. The only configuration setting you'll likely want to change is "update recursively" checkbox in the "Settings". Then if you right-click the top elphel353 directory and select "update" it will update all the project files, not just the ones in that top directory.

Setting up developer CVS access to elphel/elphel-community projects at Sourceforge

  • Get developer status from one of the project admins (elphel or elphel-community), your_sf_username below is your Sourceforge user name
  • Create SSH key for you computer (with empty pass phrase ) and post it at sourceforge (posting is on you personal page, not on the project page)
ssh-keygen -t dsa -C " your_sf_username@elphel.cvs.sourceforge.net"

or 

ssh-keygen -t dsa -C " your_sf_username@elphelcommunity.cvs.sourceforge.net"

Agree with defaults, use empty passphrase You will get 

Your public key has been saved in (your home directory)/.ssh/id_dsa.pub.

Copy the long line related to this host, something like 

ssh-dss AAAAB... (clipped) ...Gvs your_sf_username@elphel.cvs.sourceforge.net

to the copy buffer. Login to Sourceforge, go to your account (link "Account" on the top-right in the browser page) and scroll down until you find (number of keys may be different) 

Number of SSH Shared Keys on file: 0 [Edit SSH Keys for Shell/CVS]
  • And then open Edit SSH Keys for Shell/CVS link (that direct link here should also work if you are already logged in to Sourceforge ). Paste the "ssh-dss ... @elphel.cvs.sourceforge.net" line into the form (it will end with elphelcommunity.cvs.sourceforge.net if you are working with "elphel-community", not "elphel" repository), submit the changes.
  • Next step - you need to connect manually to the repository using ssh:
ssh your_sf_username@elphel.cvs.sourceforge.net

or 

ssh your_sf_username@elphelcommunity.cvs.sourceforge.net

The server will throw you away, but before that you'll agree to connect to that server so the system (your computer, not the Sourceforge) will not try to ask the scripts or Cervisia about it later. 

Welcome to *.cvs.sourceforge.net
This is a restricted Shell Account
You cannot execute anything here.
Connection to elphel.cvs.sourceforge.net closed.

Sourceforge states that there could be delay between posting a key and it becoming active, but it always worked for me immediately. If you do not see "Welcome to *.cvs.sourceforge.net" - try it later or recheck steps above and your CVS permissions in elphel/elphel-community projects.

  • If you got that "Welcome..." you are now ready to update CVS information (in those 'CVS' directories) to use developer access. First - remove the 'CVS' directory from the top directory of the project ('elphel353/CVS' by default), you do not need to remove CVS in subdirectories. Then re-run 
make update

And use your_sf_username when prompted (no password will be asked, security will rely on that key generated and posted above)

  • All done, now you can use CVS (and Cervisia) with commit, in Cervisia it is right-click on the file(s) and select "commit" in the context menu.

How to contribute to Elphel CVS

A dedicated sourceforge project has been started, "elphel-community",

for which anyone can obtain CVS access through sourceforge.


The goal is to overcome the need to freeze the official Elphel CVS at some times

(to issue stable releases), without having to resolve unexpected third party import

related conflicts first.


Changes in the main elphel cvs branch will be incorporated in the community cvs branch,

and changes in the community version will be imported into the official cvs as much as

possible, after validation.



Because Sourceforge users have only limited Sourceforge CVS access, it is

not possible to recover cleanly from wrong CVS commands that create new directories.

You need to be sure twice before importing files or comitting changes, to avoid

blocking the cvs waiting for a sourceforge admin action.


TIP: You can always(?) check what's going to be made, running your cvs command with -d:pserver:...

instead of -d:ext:... so that write permission is rejected at the end of the command execution.


Checkout this branch: 

cvs -z3 -d:pserver:anonymous@elphelcommunity.cvs.sourceforge.net:/cvsroot/elphelcommunity co -P elphel353-7.1-community

Update your local version: 

cd elphel353-7.1-community && cvs -z3 -d:pserver:anonymous@elphelcommunity.cvs.sourceforge.net:/cvsroot/elphelcommunity udpate


Add files or directories to the repository:

  • 1 - add the new files to the CVS, remove old ones that are not replaced, if any (don't need to commit changes yet, but if you do - update first)
  • 2 - edit src.list to add those new files, comment out the old unneeded ones with '#', files in the same level should go in alphabetical order. Run ./diff_srclist_cvs script in the top directory, make sure it comes out with empty output
  • 3 - modify Makefile in your installation directory so it will install the new files (and do not install old ones if you removed them!)
  • 4 - in the case you added the new subdirectory with it's own Makefile that needs to run during build - edit subdirs.list and add you directory. Usually the new directories are added the very end (if none other depend on them)
  • 5 - currently there is no automatic way to verify that Makefile will not try to use non-existent (in src.list, CVS) files, so it would be nice if you run top make now, generate source archive and install it in the new directory, making sure 'make' is happy and was able to find everything it needed. If you got any problems at this stage and do not have immediate solution - just remove this directory from the subdirs.list until the issue is resolved. If you do this and if the ./diff_srclist_cvs output is empty - it is safe to commit changes to the CVS without breaking installation.
  • 6 - update from the CVS first before making any commits. You can use "make update" command from the top directory
  • 7 - commit all the changes made to the CVS (add/remove files, modified src.list, Makefile(s)), provide descriptive commit messag


cd elphel353-7.1-community && cvs -z3 -d:ext:USER@elphelcommunity.cvs.sourceforge.net:/cvsroot/elphelcommunity add <file> -m "description"

Upload your local changes: 

cd elphel353-7.1-community && cvs -z3 -d:ext:USER@elphelcommunity.cvs.sourceforge.net:/cvsroot/elphelcommunity commit -m "descritpion"

Technical details (for Elphel stuff) about repository setup and update:


The elphel-community cvs is copied from the elphel cvs with the following script

(assuming there is no more than one copy per day, else add the time in $DATE)


Note: Maybe the same script can be used to update the elphel-community CVS,

and the same procedure with the offical CVS, but it is untested.


The current directory name is not important and it is not necessary to rename

the directory using the name of the branch, but i did it to clarify (hope it does). 


#!/bin/sh -e

DATE=`date +%Y%m%d`

USERNAME=$1
[ -z "$USERNAME" ] && USERNAME=$USER

rm tmp.cvs.* -rf 2>/dev/null || true
mkdir tmp.cvs.$$
cd tmp.cvs.$$

cvs -z3 -d:pserver:anonymous@elphel.cvs.sourceforge.net:/cvsroot/elphel co -P elphel353-7.1
mv elphel353-7.1 elphel353-7.1-community
cd elphel353-7.1-community

cvs -z3 -d:ext:$USERNAME@elphelcommunity.cvs.sourceforge.net:/cvsroot/elphelcommunity import -m "Import of  elphel353-7.1-cvs-$DATE" elphel353-7.1-community ELPHEL353_DIST ELPHEL353_7_1_CVS_$DATE

cd ../..
rm tmp.cvs.$$ -rf

Other possibility for updating the elphel-community cvs with the elphel cvs 

# (Untested procedure)
# For updating elphel-community, maybe we can also/must instead copy the community directory

mkdir tmp.cvs.$$
cd tmp.cvs.$$
cvs -z3 -d:pserver:anonymous@elphelcommunity.cvs.sourceforge.net:/cvsroot/elphelcommunity co -P elphel353-7.1-community
cd elphel353-7.1-community
 
# then update from the official cvs with:
if ! cvs -z3 -d:pserver:anonymous@elphel.cvs.sourceforge.net:/cvsroot/elphel update ; then

# resolve conflicts manually
   exit   
   /bin/sh

fi

# and commit changes

cvs -z3 -d:ext:$USERNAME@elphelcommunity.cvs.sourceforge.net:/cvsroot/elphelcommunity commit

cd ../..
rm tmp.cvs.$$ -rf
