Hg - Find tags that "cover" specific file version

Question

We use hg to control the sources for a large project. Whenever we do a release, we tag the version in hg.

Now say I take a specific revision (where I've fixed a bug for example). I want to know which releases contain this fix, i.e. which tags "cover" this revision.

How do I find this? In hg tags seem to refer only to the tagged changeset. I remember that in ClearCase every ancestor of the tagged revision would be marked too, is there a way to see this information in hg?

Thanks!

Answer 1

Revsets without any additional extensions can give you something. like

hg log -r "id(hash):tip and tag()" or shorter and nicer (maybe) version hg log -r "descendants(hash) and tag()"

Just and example of shortened revset from my repo with merges after revision in question

>hg glog -r "descendants(c9e3b41ec78f)"

And comparing output of two forms of revsets (same output anyway)

descendants()

>hg log -r "descendants(c9e3b41ec78f)" --template "{rev}:{node|short}\n"
59:c9e3b41ec78f
60:1393fe759096
61:e7ae9e5f725a
62:eed6619dadb8
63:c778bae76563
64:625d08492555
65:f202d72d6397

Direct range definition

>hg log -r "id(c9e3b41ec78f):tip" --template "{rev}:{node|short}\n"
59:c9e3b41ec78f
60:1393fe759096
61:e7ae9e5f725a
62:eed6619dadb8
63:c778bae76563
64:625d08492555
65:f202d72d6397

Answer 2

This gives the output similar to hg tags:

hg log -r "reverse(descendants(8bb6)) and tag()" --template "{tags}\t{rev}:{node|short}\n"
