Safely Rewriting History
""""""""""""""""""""""""
Obsolescence markers make it possible to mark changesets that have been
deleted or superset in a new version of the changeset.
Unlike the previous way of handling such changes, by stripping the old
changesets from the repository, obsolescence markers can be propagated
between repositories. This allows for a safe and simple way of exchanging
mutable history and altering it after the fact. Changeset phases are
respected, such that only draft and secret changesets can be altered (see
'hg help phases' for details).
Obsolescence is tracked using "obsolete markers", a piece of metadata
tracking which changesets have been made obsolete, potential successors
for a given changeset, the moment the changeset was marked as obsolete,
and the user who performed the rewriting operation. The markers are stored
separately from standard changeset data can be exchanged without any of
the precursor changesets, preventing unnecessary exchange of obsolescence
data.
The complete set of obsolescence markers describes a history of changeset
modifications that is orthogonal to the repository history of file
modifications. This changeset history allows for detection and automatic
resolution of edge cases arising from multiple users rewriting the same
part of history concurrently.
Current feature status
======================
This feature is still in development. If you see this help, you have
enabled an extension that turned this feature on.
Obsolescence markers will be exchanged between repositories that
explicitly assert support for the obsolescence feature (this can currently
only be done via an extension).

Creating And Updating Changeset
===============================
Setup the Base Repo
-------------------
We start with a plain base repo::
$ hg init main; cd main
$ cat >main-file-1 <<-EOF
> One
>
> Two
>
> Three
> EOF
$ echo Two >main-file-2
$ hg add
adding main-file-1
adding main-file-2
$ hg commit --message base
$ cd ..
and clone this into a new repo where we do our work::
$ hg clone main work
updating to branch default
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ cd work
Create First Patch
------------------
To begin with, we just do the changes that will be the initial version of the changeset::
$ echo One >file-from-A
$ sed -i'' -e s/One/Eins/ main-file-1
$ hg add file-from-A
So this is what we would like our changeset to be::
$ hg diff
diff --git a/file-from-A b/file-from-A
new file mode 100644
--- /dev/null
+++ b/file-from-A
@@ -0,0 +1,1 @@
+One
diff --git a/main-file-1 b/main-file-1
--- a/main-file-1
+++ b/main-file-1
@@ -1,1 +1,1 @@
-One
+Eins
To commit it we just - commit it::
$ hg commit --message "a nifty feature"
and place a bookmark so we can easily refer to it again (which we could have done before the commit)::
$ hg book feature-A
Create Second Patch
-------------------
Let's do this again for the second changeset::
$ echo Two >file-from-B
$ sed -i'' -e s/Two/Zwie/ main-file-1
$ hg add file-from-B
Before committing, however, we need to switch to a new bookmark for the second
changeset. Otherwise we would inadvertently move the bookmark for our first changeset.
It is therefore advisable to always set the bookmark before committing::
$ hg book feature-B
$ hg commit --message "another feature (child of $(hg log -r . -T '{node|short}'))"
So here we are::
$ hg book
feature-A 1:568a468b60fc
* feature-B 2:73296a82292a
Fix The Second Patch
--------------------
There's a typo in feature-B. We spelled *Zwie* instead of *Zwei*::
$ hg diff --change tip | grep -F Zwie
+Zwie
Fixing this is very easy. Just change::
$ sed -i'' -e s/Zwie/Zwei/ main-file-1
and **amend**::
$ hg amend
This results in a new single changeset for our amended changeset, and the old
changeset plus the updating changeset are hidden from view by default::
$ hg log
