log: remove dead code to follow descendants if ascending revisions specified It's been disabled since 8b4b9ee6001a "log: make -fr show complete history from the given revs" 2015-02-06, and we've got no bug report regarding this exact behavior. For details what the heck "followdescendants" is, please see the issue comment: https://bz.mercurial-scm.org/show_bug.cgi?id=4959#c72 "'rev(%d)' % startrev" can be replaced with '.' since revs are 'reversed(:.)'.

log: duplicate _logrevs() dedicated for walkchangerevs() Prepares for refactoring getlogrevs() to fix the "log -frREV PATH" issue. I initially thought I could get rid of walkchangerevs(), but it turned out requiring non-trivial work because of a "prepare" callback and a scanning window. This patch makes sure that walkchangerevs() will be unaffected by subsequent changes.

update: fix crash on bare update when directaccess is enabled 'rev' may be None. An empty 'rev' string shouldn't also be passed to unhidehashlikerevs().

templater: make sure expression is terminated by '}' This can't be ensured by the tokenize() generator since the parser stop consuming tokens once it reached an end of an operation. Spotted by Matt Harbison.

bookmark: deprecate direct update of a bookmark value This changeset was part of an older series preventing direct update of the bookmarks store without the change being tracked by a transaction. For some unclear reason, this was not sent to the list. So we are sending it now. Initial series: 3325c7dcabaa+08bf0ebc6c8e+712a85b3677f. We want to channel all bookmarks update through 'applychanges' so let's remove more way to work around this function.

svnsubrepo: check if subrepo is missing when checking dirty state (issue5657) During an hg convert command, subrepos are not checked out. However, a manifestmerge may occur during an hg convert if there is a merge commit, which in particular will check the dirty state of subrepos. Before this change, the lack of a checked out subrepo would error out. This check for svn subrepos is modelled after 2fdea636f254 for git subrepos.
