push: restrict common discovery to the pushed set
This changeset make use of the ability of the set discovery to only search
common changeset for a subset of the repository. Restricting that search to the
pushed set avoid potential waste of time finding out the status of many
unrelated related revision.
Repository with many heads were especially badly affected by this. Here is an
example of findcommonhead discovery for pushing 11 outgoing changeset on a
repository with tens of thousand of unrelated heads. (discovery run over a ssh
link to localhost).
Before:
queries: 92
time: 44.1996s
After:
queries: 3
time: 0.6938s
A x63 speedup even with a network link without latency.

======== hg-ssh ======== ---------------------------------------- restricted ssh login shell for Mercurial ---------------------------------------- :Author: Thomas Arendsen Hein <thomas@intevation.de> :Organization: Mercurial :Manual section: 8 :Manual group: Mercurial Manual .. contents:: :backlinks: top :class: htmlonly :depth: 1 Synopsis """""""" **hg-ssh** repositories... Description """"""""""" **hg-ssh** is a wrapper for ssh access to a limited set of mercurial repos. To be used in ~/.ssh/authorized_keys with the "command" option, see sshd(8): command="hg-ssh path/to/repo1 /path/to/repo2 ~/repo3 ~user/repo4" ssh-dss ... (probably together with these other useful options: no-port-forwarding,no-X11-forwarding,no-agent-forwarding) This allows pull/push over ssh from/to the repositories given as arguments. If all your repositories are subdirectories of a common directory, you can allow shorter paths with: command="cd path/to/my/repositories && hg-ssh repo1 subdir/repo2" You can use pattern matching of your normal shell, e.g.: command="cd repos && hg-ssh user/thomas/* projects/{mercurial,foo}" You can also add a --read-only flag to allow read-only access to a key, e.g.: command="hg-ssh --read-only repos/\*" Bugs """" Probably lots, please post them to the mailing list (see Resources_ below) when you find them.
