ClearCase 'checkout' implementation

[Wim Deblauwe]

Hi,

to make release:perform work on ClearCase we need to implement the 'checkout' command for ClearCase (this is not what ClearCase user would call checkout!). As I understand it, 'checkout' should copy the files (with a certain tag) from the source control system to a certain directory and then the build should start on those files. So this is what we need for ClearCase:

- create a view with a config spec: Since we need to look at a released version and it has been labeled in release:prepare if all is ok, we only need 1 line in the config spec, like this

ELEMENT * RLS_MYPROJECT_V1.0

- mount the correct vob. Don't know if this is really necessairy, the correct vob should normally already be mounted
- cd to the created view
- copy everything to a directory (or run the build from the newly created view?)

This is the commando's I think we will need to call:

// First create the view
cleartool mkview -tag maven_release_build_view \\MYCOMPUTER\cc_vws1\maven_release_build_view.vws
// Assign the correct config spec
[Create a temp file called configspec.txt with the config spec in it]
cleartool setcs -tag maven_release_build_view configspec.txt
[Following 2 lines maybe better left out for now]
cleartool umount -all
cleartool mount \my_own_vob

//Do the build here

//Call the following line after the build - If this is not possible to call after the build, run it at the start of the next build
cleartool rmview -force -tag maven_release_build_view


anybody who agrees or disagrees, please comment!

regards,

Wim
