dummy merge (two branches) for dummies

[Uwe Brauer]

Hi

Thanks very much!

    > After that here are three example merges that keep foo changes:

    > 1) hg update uwe
    >    hg merge foo --tool internal:other
    >    hg commit -m "Merge foo internal:other"

    > 2) hg update foo
    >    hg debugsetparents uwe foo
    >    hg branch uwe
nitpicking that should be hg merge uwe ? :-D

    >    hg commit -m "Merge using debugsetparents"

    > 3) hg update uwe
    >    hg merge foo --tool internal:other
    >    hg revert --all -r foo
    >    hg commit -m "Merge foo, discard uwe changes"

    > Note: The contents of foo.txt is the same in all examples.

    > In example 1, uwe changes to all files that foo knows about are
    > discarded but new files uwe adds are kept. In example 2, uwe changes
    > to files also changed by foo are discarded but all other uwe changes
    > are kept. (See contents of uwe1.txt.)

Ok that difference is very important. Thanks to Simon the command


hg log -r "adds('.')" --template '{rev} {desc|firstline}\n{file_adds}\n\n'

Tells me


0 Uwe one
test.txt uwe1.txt

1 Foo two
foo.txt

3 Uwe four
uwe2.txt

That uwe2.txt was added after the last commit to the foo branch.

It is very important to be aware of this essential difference between
option 1 and 2, I might need both in different contexts.

Thanks again for this elaborate answer, I copied right away in my
README-HG file.
