util: clean up function ordering

notify: change behavior of "changegroup" hook Change the behavior so that the sender (the "From" header in the notification mail) in case of the "changegroup" hook is the user that did the first commit in the changegroup. The option is configurable, if you set "notify.fromauthor" to "True" in your config, the new behavior is activated. If you do not set the option, the behavior is as before. The commit adds to an existing test to show various aspects of the changed behavior.

largefiles: optimize status when files are specified (issue3144) This fixes a performance issue with 'hg status' when files are specified on the command-line. Previously, a large amount of largefiles code was executed, even if files were specified on the command-line and those files were not largefiles. This patch fixes the problem by first checking if non-largefiles were specified on the command-line and, just letting the normal status function handle the case if they were. On a brand new machine, the execution time for 'hg status filename' on a repository with largefiles was: real 0m0.636s user 0m0.512s sys 0m0.120s versus the following (the same repository, with largefiles disabled): real 0m0.215s user 0m0.180s sys 0m0.032s After this patch, the performance of 'hg status filename' on the same repository, with largefiles enabled is: real 0m0.228s user 0m0.189s sys 0m0.036s This performance boost is also true when patterns (rather than specific files) are specified on the command-line. In the case where patterns are specified in addition to a file list, we just defer to the normal codepath in order to not spend extra time expanding the patterns to just risk having to expand them again later.

wireproto: handle other server output in pushkey Remote side may add useful information alongside failure return code. For example "ssl is required". This patch mirror what is done for the unbundle command.

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)
