Enstaller

-------------------

Main highlights:

Improvements:

* add --no-autoupdate to disable auto update from the CLI (528)

Bug fixes:

* Fix race condition when fetching indices (449).
* Fix wrong IAuth definition (446).
* Fix running enpkg as root (458)
* Fix enpkg --prefix handling (473)
* Fix enpkg --config-path to expand ~ (487)
* Fix virtualenv detection to work w/ venv (3.3+)
* Fix etag handling when using both python 2 and 3 (497, 500)
* Ignore caching errors when getting values from it (521)
* Fix handling of default when prompting for user input (526)

Internals:

* new internal tool enstaller.tools.unpack, used for some low-level build
tasks at Enthought.
* commands implementations are now decoupled from argparse namespace, for
easier reuse.
* remove obsolete enstaller.indexed_repo
* unbundle every dependency

-------------------

Main highlights:

* added support for python 3 (>= 3.3) and pypy (274)
* http connections consolidated, CA certificates validated everywhere by
default.
* Add -k/--insecure option to ignore CA certification checks.
* enstaller now provides a proper user-agent when accessing a remote
server (319)
* token-based authentication when using brood store (266). One can also
use API token instead of passwords.
* enpkg now retries downloading eggs when checksum mismatch occurs
before bailing out (278), and retry connection failures as well (350)
* indices are fetched in parallel (424)
* new bootstrap script that works on every platform and is more reliable
than the old build.sh hack (320)
* `.enstaller4rc` is now searched in the following order:
* sys.prefix
* user's home directory
* parent virtualenv (when applicable)

Bug fixes:

* pypi confirmation is asked before resolving dependencies (323)
* fix enpkg crash when atom is installed over gdata (338)
* enpkg --info "last modified" output has been restored (296)

Internals:

* dependency resolution is now in enstaller.solver. The new Solver class only
resolve dependencies (install/remove action, no fetch action anymore)
* http handling has been consolidated in the Session class. Authentication is
now pluggable through the IAuthManager.
* test suite does not access network anymore. Http tests handled through
the response library (285)
* add a new YAML-based configuration (not enabled yet).
* Auth configuration has been consolidated and is now pluggable
(currently supports storing authentication as username/password or api
token).
* enstaller.tools.repack added (replacement of endist `build_egg -r`).
This feature requires okonomiyaki >= 0.3.3 (available in Enthought'
repositories and on pypi).

-------------------

Main highlights:

* authentication handling has been streamlined. When credentials are missing
and/or invalid, enpkg displays an error message instead of crashing (144).
* enpkg always uses the same authentication method, whether keyring is
installed or not.
* support for python 2.5 has ben dropped
* add use_pypi = True/False configuration entry to enable/disable pypi repo
access (True by default)
* add enpkg-repair script to fix .egg-info directories
* egginst and enstaller now use logging instead of print statements. Verbose
output may be obtained through 'enpkg -v', very verbose through
'enpkg -v -v'.
* add the -y option to automatically answer yes everytime enpkg prompt the
user for confirmation
* ask for confirmation when installing unsupported pypi eggs

Bug fixes:

* 144: enpkg crashed when credentials were invalid, or when requesting
packages requiring credentials while not authenticated.
* 149: handle invalid proxy strings gracefully.
* Handle Ctrl+C gracefully, and don't print a traceback anymore. Returns an
exit code of 130, as usually returned by aborted programs on Unix.

Internals:

* enstaller internal configuration is not a singleton anymore.
* Store classes are gone, and Repository instances are used instead
* Enpkg class is now only concerned with execution: dependency resolution is
done through a separate Solver class. It also allows for iterator-based
execution for integration with 3rd party packages.
* urllib* has been replaced by requests
* configuration is properly parsed instead of being exec'd.
* remove undocumented and unused 'enpkg --revert file' feature.
* remove undocumended hook feature

-------------------

Main highlights:

* Add support for cancellation in fetch API
* Undocumented feature --freeze/--requirement (used internally Enthought
only)
* Don't print the traceback when crashing anymore, unless ENSTALLER_DEBUG is enabled
* Egginst now installs eggs in a way that follows easy_install more closely.
In particular, entry points should now be recognized correctly.

The project setup has been significantly improved however:

* Code coverage nearly doubled
* Unused code (e.g. hook feature) has been removed from egginst
* Added requirements for dev + tox setup + travis-ci + coveralls.io

-------------------
* Fix bugs in --update-all and --revert
* Improve help text

-------------------
* Adding an --update-all switch to enpkg.
* Usability improvements, improved warnings.
* Improve --prefix support.
* Support for softlinks inside eggs.
