The config goes in the 'server' section because it feels like something the server owner would want to decide. We pick and open field because it seems likely that other checking levels will emerge in the future. (eg: server like the mozilla-try server will likely wants a "none" value) The option name contains 'push' since this affects 'push' only. The option value 'check-related' is preferred over one explicitly containing 'allow' or 'deny' because the client still have a strong decision power here. Here, the server is just advising the client on the check mode to use. diff --git a/mercurial/bundle2.py b/mercurial/bundle2.py --- a/mercurial/bundle2.py +++ b/mercurial/bundle2.py @@ -1323,7 +1323,8 @@ def getrepocaps(repo, allowpushback=Fals caps['obsmarkers'] = supportedformat if allowpushback: caps['pushback'] = () - if not repo.ui.configbool('experimental', 'checkheads-strict', True): + cpmode = repo.ui.config('server', 'concurrent-push-mode', 'strict') + if cpmode == 'check-related': caps['checkheads'] = ('related',) return caps diff --git a/mercurial/help/config.txt b/mercurial/help/config.txt --- a/mercurial/help/config.txt +++ b/mercurial/help/config.txt @@ -1672,6 +1672,16 @@ Controls generic server settings. are highly recommended.
