[Monotone-devel] question about how a selective log displays head nodes

[Hugo Cornelis]

Hi all,


We are maintaining documentation in a monotone repository.  In the
workspace on my laptop I invoke:

$ mtn automate heads
970f659a5173b3b0183ab4a70986a033ce107cf1

So I assume the branch (name: 0) has only one head.

There is a document I am working on, it is called
cbi-scripting/cbi-scripting.tex and it is under monotone control.

Within xemacs I invoke the following shell command from the root
directory of the local workspace:

mtn log --last 100 cbi-scripting/

which gives (abbreviated output of the first N revisions, removed the
ChangeLog entries, a fixed width font should show the bars lined up) :

o-.-.-.-.-.-.-.-.-.-.-.-.     (Revision:
970f659a5173b3b0183ab4a70986a033ce107cf1)

| .-----.-.-.-.-.-.-.-.-.-o-.     (Revision:
9a2816511d9ce21cb246affbbd4f7156a567fa63)

etc...

In this output both Revision: 970f659a5173b3b0183ab4a70986a033ce107cf1
and Revision: cd3ecf3fc142b98b457aba8df5795c884e74147e are listed as
heads.

I then invoke:


$ mtn log --revision 54d833b5c9b9e7e649096fa6ee52be3b724836e1
o   ----------------------------------------------------------------------

|

which lists cd3ecf... as its parent revision.  So clearly cd3ecf... is
not a head.

I would have expected that the selective log format would insert
additional revision records between parenthesis when needed to prevent
confusion about ancestry of the displayed revisions.  So I am
surprised that the selective log format displays cd3ecf... as a head
node.

Is this to be expected?

Thanks,
