phases: exchange phase boundaries on push For now phase sync is tried even if push fails with some know pathological case. The exact behavior is to be discussed and implemented later.

phases: exchange phase boundaries on pull Add an extra argument to addchangegroup to all phase code to execute before the lock is released.

phases: add a function to compute heads from root

phases: add basic pushkey support

phases: update exchange test to include node hash. This will be easier for exchange test.

phases: add a phases.publish option What is a "publishing repository"? ================================== Setting a repository as "publishing" alter its behavior **when used as a server**: all changesets are **seen** as public changesets by clients. So, pushing to a "publishing" repository is the most common way to make changesets public: pushed changesets are seen as public on the remote side and marked as such on local side. Note: the "publishing" property have no effects for local operations. Old repository are publishing ============================= Phase is the first step of a series of features aiming at handling mutable history within mercurial. Old client do not support such feature and are unable to hold phase data. The safest solution is to consider as public any changeset going through an old client. Moreover, most hosting solution will not support phase from the beginning. Having old clients seen as public repositories will not change their usage: public repositories where you push *immutable* public changesets *shared* with others. Why is "publishing" the default? ================================ We discussed above that any changeset from a non-phase aware repository should be seen as public. This means that in the following scenario, X is pulled as public:: ~/A$ old-hg init ~/A$ echo 'babar' > jungle ~/A$ old-hg commit -mA 'X' ~/A$ cd ../B ~/B$ new-hg pull ../A # let's pretend A is served by old-hg ~/B$ new-hg log -r tip summary: X phase: public We want to keep this behavior while creating/serving the A repository with ``new-hg``. Although committing with any ``new-hg`` creates a draft changeset. To stay backward compatible, the pull must see the new commit as public. Non-publishing server will advertise them as draft. Having publishing repository the default is thus necessary to ensure this backward compatibility. This default value can also be expressed with the following sentence: "By default, without any configuration, everything you exchange with the outside is immutable.". This behaviour seems sane. Why allow draft changeset in publishing repository ===================================================== Note: The publish option is aimed at controlling the behavior of *server*. Changeset in any state on a publishing server will **always*** be seen as public by other client. "Passive" repository which are only used as server for pull and push operation are not "affected" by this section. As in the choice for default, the main reason to allow draft changeset in publishing server is backward compatibility. With an old client, the following scenario is valid:: ~/A$ old-hg init ~/A$ echo 'babar' > jungle ~/A$ old-hg commit -mA 'X' ~/A$ old-hg qimport -r . # or any other mutable operation on X If the default is publishing and new commits in such repository are "public" The following operation will be denied as X will be an **immutable** public changeset. However as other clients see X as public, any pull//push (or event pull//pull) will mark X as public in repo A. Allowing enforcement of public changeset only repository through config is probably something to do. This could be done with another "strict" option or a third value config for phase related option (mode=public, publishing(default), mutable)
