Questions[mercurial](server)

I have Mercurial repositories running on Apache with mod_wsgi. Repositories have all filenames encoded in windows-1251. This encoding is used for historically reasons: they were converted to mercurial from svn, windows-1251 is default windows encoding for russian locale.

Now programmers want to use Crucible tool for code review. It can't undersand filenames in any other encoding than utf-8. So I need to convert them from windows-1251 to utf-8. Does anyone know how to do this? Mercurial convert extension doesn't have options to convert encodings.

hgweb.config:

[web]
#encoding = UTF-8
encoding = windows-1251
#allow_archive = gz, zip, bz2
allow_archive = zip
allow_push = *
push_ssl = false

We are just switching to Mercurial where I work this week. I'm starting to read material, and was hoping somebody could succinctly answer this question:

What's the difference between Mercurial's "tip" tag and the "default" branch?

I am evaluating the possibilities of moving my organisation to Mercurial, however I am stumbling on two basic requirements which I can't find proper pointers to.

How do I set up Mercurial's central repository to authenticate users with the central Active Directory and only allow them to push or pull if they have the right credentials?

How do I set up a Mercurial project repository to only allow users pertaining to a specific group to push/pull source code? We need this to have per-project authorisation.

On which HTTP servers (IIS or Apache etc.) are the above two requirements supported?

Apologies if I am asking something obvious or if I am missing something fundamental about how authentication and authorisation works.

I'm trying to configure mercurial access using Apache http. It requires authentication. My /etc/apache2/sites-enabled/mercurial looks like this:

NameVirtualHost *:8080

<VirtualHost *:8080>
    UseCanonicalName Off
    ServerAdmin  webmaster@localhost
    AddHandler cgi-script .cgi
    ScriptAliasMatch ^(.*) /usr/lib/cgi-bin/hgwebdir.cgi/$1
</VirtualHost>

Every tutorial I read on the internet tells me to insert these lines:

AuthType Basic
AuthUserFile /usr/local/etc/httpd/users

But when I do it I get the following error:

# /etc/init.d/apache2 reload
Syntax error on line 8 of /etc/apache2/sites-enabled/mercurial:
AuthType not allowed here

My distro is a customized Ubuntu called Turnkey Linux Redmine

This is somewhat related to this question but is a different question.

We have a central Hg repository, served to users via SSH and mercurial-server. We have a number of Mac, Linux and Windows clients connecting to it.

It has happened twice now that one of the Windows users has corrupted their repository, then pushed back to the central one corrupting it. I want to write an incoming hook script on the central repository to prevent a transaction from being accepted if it will corrupt the central repo.

Although unfortunately I don't know enough about Mercurial to write such a script. Any possibility that someone else has come across this? Personally I'm not quite sure why hg doesn't do this by default.
