What do you think is the best practice for checking in code from multiple files that implement multiple changes, but are ready to go in at one time?
Do you check them all in at once, keeping the checking reasonably atomic, and put the changes in one long comment?
Do you check in the files in groups so the right comment is associated with the right file?
Do you have tools which let you check in at once with different comments on different files?
Check all at once. If you check in groups you make break the build.
But it is better to check in as you get the change done.
