the procedure that should be used is:

* edit and save
* git diff (to check and review the current status of work in progress)
* git commit
* git pull
* git push
* *RELOAD* all editor windows (or use an editor that auto-detects)

the process that you used, we may deduce that it was:

* edit and save
* git pull
* re-save local file WITHOUT CHECKING
* git commit
* git push

can you please:

1) adjust working practices to the first process
2) restore the erased code
3) close this bugreport when done

thanks.

excellent, thank you.

I changed my editor settings to that it that auto-detects when a file was changed by an external program.

great.

can you also restore this:

class DataMergerRecord(Record):
    """
    {data: 128 bit, byte_enable: 16 bit}
    """

    def __init__(self, name=None):
        layout = (('data', 128),
                  ('en', 16))
        Record.__init__(self, Layout(layout), name=name)

        #FIXME: make resetless

those lines are already present in the code, at least on my local code which I recently git pulled.

yes.  which means that you overwrote some code which is *not* present.
can you please carefully examine the commit and restore all of the code.

also, i am reverting the recent commit because it does not work.

excellent, you found it.  closing again.
