First step in two-part process to rename directories to kallithea.
This first step is to change all references in the files where they refer
to the old directory name.

Imported some of the GPLv3'd changes from RhodeCode v2.2.5.

This imports changes between changesets 21af6c4eab3d and 6177597791c2 in
RhodeCode's original repository, including only changes to Python files and HTML.

RhodeCode clearly licensed its changes to these files under GPLv3
in their /LICENSE file, which states the following:
The Python code and integrated HTML are licensed under the GPLv3 license.

(See:
https://code.rhodecode.com/rhodecode/files/v2.2.5/LICENSE
or
http://web.archive.org/web/20140512193334/https://code.rhodecode.com/rhodecode/files/f3b123159901f15426d18e3dc395e8369f70ebe0/LICENSE
for an online copy of that LICENSE file)

Conservancy reviewed these changes and confirmed that they can be licensed as
a whole to the Kallithea project under GPLv3-only.

While some of the contents committed herein are clearly licensed
GPLv3-or-later, on the whole we must assume the are GPLv3-only, since the
statement above from RhodeCode indicates that they intend GPLv3-only as their
license, per GPLv3§14 and other relevant sections of GPLv3.

Fixed bug with log_delete hook didn't properly store
user who triggered delete action

action logger will try to get IP address automatically based
on tmpl_context var (if defined)

accept that repos are read-only - very convenient for testing.

Users are prompt to confirm they want to use read only paths.

moved top-level tests to rhodecode/tests/other.

- There are no toplevel tests
- moved proper files to fixtures where they should be in the first place

synced vcs with upstream

- moved subprocessio module to VCS
- many small changes to make embedded vcs as similar to to external lib
- use only absolute imports
- patch vcs config during load pylons env

invalidation: don't create CacheInvalidation records on startup

Creating the records early gave an advantage before lightweight was introduced.
With lightweight it is no longer necessary.

The records will be created on demand anyway and there is no reason to create and
maintain them before they are used.

invalidation: merge .invalidate and .set_valid as .test_and_set_valid

This simplifies the internal API and avoids leaking CacheInvalidation instances
and cache keys.

- Manage User’s Groups: create, delete, rename, add/remove users inside.
by user group admin.
In this case, a user's group can be owned by several people thru an owner user's group.

Some refactoring of naming, permission handling logic.
- remove some code duplicity as well as inconsistent naming

repo rescann should detach forks of zombie repos,
this way we ensure we do proper cleanup of such repos.

avoid %r markup of unicode strings in user facing messages

Improves
Revision u'b7f4...' does not exist for this repository

better detection of deleting groups with subgroups inside.
Added less strict checks on delete group routing so we can delete zombie groups
(those that are not in filesystem but in DB)

--version command should be safe, and bare no modifications
- improved subprocess calls error detection
- fixed I/O read on closed file errors

reposcann should skip directories with starting with '.'
some code cleanup, moved all skipping to get_repos function

unified RhodeCode paster commands
- moved them to commont paster_commands package
- re-use sqlalchemy session initializaiton
- some docs updates

reposcann should skip directories with starting with '.'
some code cleanup, moved all skipping to get_repos function

logging: clarify logging of db logging

It said that a user was added ... which wasn't true.

Default parameters are now also used for creating repos using API calls, and initial repo scanner
- added new parameters to API call to override defaults
- docs update
- repo_type is now optional as it's a part of defaults

Implemented better support for Wildcard queries
add username column to journal for caching logs after user deletion
added tests for admin journal
migrations

Cleaned the way cache keys are invalidated
should fix issue #504 RhodeCode is showing different
versions of README on different summary page loads

fix for issue #602, enforce str when setting mercurial UI object. When this is used together with mercurial internal translation system
it can lead to UnicodeDecodeErrors

Add git version detection to warn users that Git used in system is to old. ref #588
- also show git version in system details in settings page

Fixing issues of cache invalidation for multiple instances running in rhodecode.
- during server start always register all cache keys for all repositories
- Don't clear cache markers on start since multiple instances can clear each other out

Added optional flag to make_ui to not clean sqlalchemy Session.
Don't clear sqlalchemy session when using make_ui in admin repo form

use os.environ as a fallback for getting special info from hooks, this will allow
calling RhodeCode hooks from outside the system eg. via SSH
- also verify repo if it's a correct VCS throw 404 error otherwise

fixed the push_ssl issues after mercurial 2.3 upgrade.
Set always to false, since rhodecode handles that by dedicated middleware.

Bumped mercurial version to 2.3
- fixed issues with compare of two remote repos at particular revisions
- added tests for cases when mercurial update broke code and tests didn't catch this
- removed obsolete EmptyChangeset from the rhodecode code

Implementes #509 require SSL flag now works for both git and mercurial.
- check is done at earlies possible stage
- if detected protocol is not https and flag require is there RhodeCode will
return HTTP Error 406: Not Acceptable, before even checking credentials
- removed push_ssl flag from mercurial UI objects since that would duplicate logic

Do cleanup on repo2db mapper
- fixed issue with install git hook function

Added option to re-install githooks to repo2db mapper, and catch exception on removal so it doesn't break
after first error

Added functional test create repo with a group
- unified calling Session in tests

Initial version of landing revisions ref #483
- fixed relevant tests for creation of repo
- added some tests for git

Added vcs testsuite for better integration tests + added fetching
of two new repos into test env for rhodecode

Implemented #467 Journal logs comments on changesets
- added created/updated user action to journal
- added created/updated users group action journal
- added ip adresses to most of action_log calls to track IP changes
- rewrote action_parser to simpler and more efficient solution

- #347 when running multiple RhodeCode instances, properly invalidates cache
for all registered servers
- server start also clears all cache keys now

utils/conf
- created temporary utils2
- made config.conf for storing some configurations
- fixed some dependency import problems
- code cleanup
- rc-extensions now properly work for celery

fixed some unicode problems with waitress
- fixed clonning repos from non-ascii groups

fixed issues with removed repos was accidentally added as groups, after
full rescan of paths

changed warning log message for reading hgrc files, it was confusing. It's just an indication of the fact
that there is no such file...

#227 Initial version of repository groups permissions system
- implemented none/read/write/admin permissions for groups
- wrote more tests for permissions, and new permissions groups
- a lot of code garden, splitted logic into proper models
- permissions on groups doesn't propagate yet to repositories
- deprecated some methods on api for managing permissions on
repositories for users, and users groups

garden
- unified logging formatting to use only %
