It seems that with the current mercurial commit code, it will always
blindly overwrite the current file with the web edited version, losing
any other changes.
+* `rcs_commit_staged`, `rcs_rename`, `rcs_remove`, and `rcs_diff` are not
+ implemented for mercurial, and so attachments, remove and rename plugins
+ and recentchangesdiff cannot be used with it. (These should be fairly
+ easy to add..)
Posthook: in `$srcdir/.hg/hgrc`, I have the following

-The problem with --post-commit is that if you delete some pages in $SRC, ikiwiki --setup setupfile --post-commit will not delete them in $DEST.
+The problem with --post-commit is that if you delete some pages in $SRC, ikiwiki --setup setupfile --post-commit will not delete them in $DEST. --[[users/weakish]]
-I add the following to .hg/hgrc:(I use changegroup since I don't think we need refresh per changeset, please point out if I am wrong.)
-
- [hooks]
- changegroup = hg update >&2 && ikiwiki --setup path.to.setup.file --refresh
- post-commit = ikiwiki --setup path.to.setup.file --refresh

-I tried the follwing commands in $SRC:

+> set, and running the wrapper generated by that from your hook.

-No deadlock happens. (Also I push to the $SRC from another machine, again, no deadlock. If there is conflicts between $SRC and my own repo, hg pull will abort. You have to pull, merge and push again.)

-Of course these tests are too simple. The problem is I have no idea when the deadlock will happen. If someone is kind enough to point out, I will run more test.
