VMM//{,cli/}Handler: PEP-8-ified the Handler classes: * converted CamelCase method names to lower_case_with_underscores * eliminated __names * added missing docstrings

VMM//{,cli/}Handler: Reworked configuration related parts. Renamed attributes _Cfg -> _cfg; _cfgFileName -> _cfg_fname. Renamed methods __chkCfgFile -> __check_cfg_file; __findCfgFile -> __find_cfg_file. Added missing docstrings.

VMM/constants: Added __copyright__.

VMM/constants: Replaced the constants subpackage by a module.

VMM/cli: Forgot to remove string_io from __all__.

VMM/cli: Removed misplaced function string_io.

VMM/cli/Config: Write warnings to stderr. Renamed method __saveChanges to __save_changes.

VMM/cli: w_err() call os.sys.exit only if code != 0. read_pass() write errors to stderr. And a few other small fixes.

VMM/ext/Postconf: Reworked class Postconf. Added method edit().

VMM/Handler: Reworked __domDirMake and reamed to __make_domain_dir. Removed the (now) unused method __makedir.

VMM/mailbox: Added to the repository. VMM/Handler: Integrated mailbox module. Code cleanups.

VMM/Transport: Small cosmetics.

VMM/maillocation: Dovecot >= 2.0.beta5 is required for `doveadm mailbox create -s …`

VMM/Account: s/prefix/mbformat/ and pass the dbh to MailLocation.__init__.

VMM/maillocation: Renamed MailLocation's property prefix to mbformat.

VMM/Config: Added boolean option mailbox.subscribe.

VMM/Config: Return mailbox.{folders,root} settings as Unicode.

VMM/maillocation: Reworked class MailLocation to match the new database structure.

VMM/Config: Added function check_mailbox_format().

man/de/man5/vmm.cfg.5.rst: Fixed a typo.

man/{,de/}man5/vmm.cfg.5.rst: Added mailbox.root, small updates.

VMM/Config: Added mailbox.root setting.

pgsql: Added support for different mailbox formats. - users.passwd can store sha512-crypt.hex hashes now - Added new update scripts.

pgsql: Removed old update SQL scripts.

VMM/maillocation: Code cleanups. Fixed error introduced with changeset 084300a00ee1.

VMM/Domain: removed functions ace2idna() and idn2ascii(). domainname.encode('idna')/domainname.decode('idna') works too.

VMM/Account: replaced attribute _mid : int by _mail : MailLocation.

VMM/password: added some CRYPT_* constants. Reverted modification (284:ec1966828246) in _get_salt().

VMM/password: adapted Blowfish/SHA-256/SHA-512 crypt() to recent changes in the Dovecot-2.0 source tree. VMM/Config: Added default number of encryption rounds to the configuration. man5: updated description of misc.crypt_{blowfish,sha{256,512}}_rounds.

VMM/…: re-indented long queries and error messages.

VMM/password: generate all crypt() salts w/o trailing $ sign

man5: added misc.dovecot_version to the minimal config example.

VMM/password: moved the 'scheme check' code from pwhash() to the new function verify_scheme(). VMM/Config: use verify_scheme() to check the scheme when LazyConfig.set() is called.

VMM/Config: removed the default value of misc.dovecot_version. There are too many different versions installed on different systems. So, it doesn't make much sense to have a default value.

VMM/Handler: import the errors before raising them. Rephrased the 'permission error' message.

VMM/password: Added support Blowfish/SHA-256/SHA-512 crypt(). Also updated Config and man section 5.

VMM/Handler: code cleanups in the user/alias/relocated info methods.

VMM/Handler: fixed destination check in Handler.aliasAdd().

VMM/Alias: moved the postconf stuff from the Handlers to Alias class.

VMM/{Config,Handler}: moved Config.install() to Handler.cfg_install(). Handler.cfg_install() must be called explicitly. To avoid 'strange' problems.

VMM/Handler: removed password hashing related stuff.

VMM{,/cli}/Handler: adjusted user* methods to the changes in Account. All user methods was renamed from userAction() to user_action(). Added missing docstrings.

VMM/Account: always pass the EmailAddress to the pwhash() call.

VMM/Account: some modifications and small improvements in class Account. - replaced the tid by a Transport instance - check mailbox format dependencies in _repare() - reset all attributes when the Account was deleted - don't select information, we have already, from the db - added __nonzero__() method

VMM/password: added small output check on _dovecotpw().

VMM/common: added a caching dict for version_hex()/version_str()

VMM/Config: Added method Config.install() -> global cfg_dget(). VirtualMailManager.Configuration removed -> some adjustments.

INSTALL: dropped group mail related stuff. UPGRADE: be more details about nobody's primary group.

configuration: Dropped setting misc.gid_mail. That setting was never useful, since none of the virtual users was a member of a system group.

man/{,de/}man5/vmm.cfg.5.rst: Updated descriptions of dovecotpw and password_scheme settings.

VMM: added new modules password and pycompat.hashlib. INSTALL: updated

VMM/maillocation: Use the hex version, since we are able to convert it to an string, in case of a failure.

VMM/{Account,common,Handler}: Improved version_hex(). - common: version_hex() now supports 'serials' > 16. Added version_str() as counterpart to version_hex(). - Account, Handler: updated hardcoded Dovecot versions.

VMM/{Account,common,maillocation}: Dovecot version (check) fixes. - Account: fixed versions dependencies. - maillocation: use the version string, may be uses in a error message. - common: version_hex() raises a ValueError, instead of returning 0, if the version string is invalid.
