Help: phases
Working with Phases
What are phases?
================
Phases are a system for tracking which changesets have been or should be
shared. This helps prevent common mistakes when modifying history (for
instance, with the mq or rebase extensions).
Each changeset in a repository is in one of the following phases:
- public : changeset is visible on a public server
- draft : changeset is not yet published
- secret : changeset should not be pushed, pulled, or cloned
These phases are ordered (public < draft < secret) and no changeset can be
in a lower phase than its ancestors. For instance, if a changeset is
public, all its ancestors are also public. Lastly, changeset phases should
only be changed towards the public phase.
How are phases managed?
=======================
For the most part, phases should work transparently. By default, a
changeset is created in the draft phase and is moved into the public phase
when it is pushed to another repository.
Once changesets become public, extensions like mq and rebase will refuse
to operate on them to prevent creating duplicate changesets. Phases can
also be manually manipulated with the "hg phase" command if needed. See
"hg help -v phase" for examples.
Phases and servers
==================
Normally, all servers are "publishing" by default. This means:
- all draft changesets that are pulled or cloned appear in phase
public on the client
- all draft changesets that are pushed appear as public on both
client and server
- secret changesets are neither pushed, pulled, or cloned
Note:
Pulling a draft changeset from a publishing server does not mark it as
public on the server side due to the read-only nature of pull.
Sometimes it may be desirable to push and pull changesets in the draft
phase to share unfinished work. This can be done by setting a repository
to disable publishing in its configuration file:
[phases]
publish = False
See "hg help config" for more information on config files.
Note:
Servers running older versions of Mercurial are treated as publishing.
Examples
========
- list changesets in draft or secret phase:
hg log -r "not public()"
- change all secret changesets to draft:
hg phase --draft "secret()"
- forcibly move the current changeset and descendants from public to
draft:
hg phase --force --draft .
- show a list of changeset revision and phase:
hg log --template "{rev} {phase}\n"
- resynchronize draft changesets relative to a remote repository:
hg phase -fd 'outgoing(URL)'
See "hg help phase" for more information on manually manipulating phases.
