Review remote changes offline in Mercurial

If you want to review remote changes from Mercurial offline you cannot use hg incoming. For sure there is a nice way to do it. So here is what I do to get changes from a repository to review them later without pulling them into my repo before reviewing. It also has the advantage that you can review changesets that include a given file. This is not possible with hg incoming.

Read the incoming changes and save them in a bundle file:

$ hg incoming --bundle incoming.bundle

Now you can disconnect and review them offline.

$ hg -R incoming.bundle log --no-merges -p -- hgext/
(log pops up)

The -R incoming.bundle option tells Mercurial to use the bundle as an overlay for the current repository. The –no-merges option tells Mercurial to not display merges (which I usually use for reviewing patches) and the -p option is there to display the applied patches in the output. I use — hgext/ to display only changesets related to the bookmark extension.

Everything’s good, let’s pull it:

$ hg pull incoming.bundle
pulling from incoming.bundle
searching for changes
adding changesets
adding manifests
adding file changes
added 113 changesets with 281 changes to 204 files (+1 heads)
(run 'hg heads' to see heads, 'hg merge' to merge)
