Cumulusci

Changes:

- Our robotframework library for Salesforce got a number of improvements:
- New keywords:
- `Click Header Field Link`: Clicks a link in a record header
- `Load Related List`: Scrolls to a related list and waits for it to load
- `Click Related List Button`: Clicks a button in the header of a related list
- `Click Related Item Link`: Clicks the main link for an item in a related list
- `Click Related Item Popup Link`: Clicks a link in the popup menu for an item in a related list
- Updated to `robotframework-seleniumlibrary` 3.2.0 which includes a `Scroll Element Into View` keyword.
- `Wait Until Loading Is Complete` now waits for the main body of the page to render
- `Populate Lookup Field` now tries several times in case there's an indexing delay
- Added a `-o verbose True` option to the robot task which logs each keyword as it runs.
- We now ignore errors while running the script that waits for XHRs to complete (it can fail if the page reloads before the script finishes).
- Popup notifications upon completion of a flow or task now work on Linux too, if you have the `notify-send` command from `libnotify`. On Ubuntu, install the `notify-osd` package.

Issues Closed:

- \827 Bulk data load breaks in Python 2
- \832 pip install cumulusci gets the wrong version of urllib3

* ``uninstall_packaged_incremental`` task: Added ``ignore`` option to specify components to skip trying to delete even if they are present in the org but not in the local source.

Changes

* Fixed the ``cci project init`` command, which was failing because it wanted
the project to already exist! Fixes 816. In addition, other commands
will now function without an active project or keychain when it possible
to do so. (For example, try ``cci version`` which now works when you're
not in a project directory.)
* ``update_dependencies`` task:
* Added support for installing private github repositories as dependencies.
Thanks to Anthony Backhouse (1handclapping) for the patch. Fixes 793
* Added a ``dependencies`` option to override the project dependencies.
* ``execute_apex`` task:
* Print more useful error messages when there are Apex exceptions.
* ``robot`` task:
* Our logic for automatically retrying failed selenium commands has been
encapsulated into the ``cumulusci.robotframework.utils.selenium_retry``
decorator which can be applied to a robot library class for increased
stability.
* There is now an option to pause and enter the Python debugger
after a keyword fails. Run with ``-o pdb True``.
* Revised keywords and locators to support the Winter '19 release of Salesforce
and improve stability.
* The ``Salesforce.robot`` file now includes the ``OperatingSystem`` and ``XML``
libraries from Robot Framework by default. These libraries are helpful in
building integration tests such as modifying and deploying a PageLayout
to include a field needed in Suite Setup of an integration test.
* Revised installation instructions for Windows. Thanks Matthew Blanski (Auchtor).
* Internal change: Use a thread-local variable instead of a global to track the current running task.

* It's happening! Hot on the heels of the last release, CumulusCI is making the jump to the modern era by adding **support for Python 3**! (Specifically, Python 3.6 and 3.7.) Don't worry, we'll also continue to support Python 2 for the time being. Because this is a bit more wide-reaching change than normal, we're releasing a beta first. To install the beta you'll need to explicitly request its version: ``pip install cumulusci==2.1.0b1``.
If you already have CumulusCI, after the update it will continue to run under your Python 2 interpreter. If you want to switch to the Python 3 interpreter (which is not yet required), we recommend deleting
your Python virtualenv and starting over with the instructions in the [tutorial](https://cumulusci.readthedocs.io/en/latest/tutorial.html). If you want to keep your Python 2-based virtualenv around just in case, follow those instructions but name the new virtualenv ``cci-py3`` instead of ``cci``.
* There are also some big changes to the **bulk data** tasks. Did you know CumulusCI has bulk data tasks? They are not configured by default, because we need to finish documenting them. But we'll list the changes in case someone is already relying on them:
* Fixed connection resets by downloading an entire result file before processing.
* Improved performance by processing batches in parallel, avoiding the SQLAlchemy ORM, storing inserted Ids in separate tables, and doing lookups using SQL joins rather than a separate query for each row.
* If you're using a postgres database for local storage, performance gets even better by taking advantage of postgres' ``COPY`` command to load CSV directly.
* Added a ``hardDelete`` option for bulk deletes.
* Added a ``start_step`` option for bulk loads which can be used to resume loading after an error.
* The ``push_failure_report`` task will now by default hide failures that occurred due to the "Package Uninstalled" or "Salesforce Subscription Expired" errors, which are generally benign.
* Fixed the check for newer CumulusCI versions to work around an issue with old ``setuptools``.
* Contributor change: We switched CumulusCI's own tests to run using ``pytest``.
* Internal change: We switched to the ``cryptography`` library for handling keychain encryption.

* Happy Spooky October! It's unlucky release 2.0.13, with some scary-cool improvements. Just to show you how ramped up our RelEng team is now, this release had TWENTY THREE pull requests in 12 days! From all four of your friendly SFDO Release Engineering committers. Thanks so much for continuing to use CCI for all your Salesforce automation needs.
* NEW FLOW: ci_beta_dependencies installs the latest beta of project dependencies and run tests. Includes task error when running against non-scratch orgs.
* NEW TASK: ReportPushFailures pulls a list of Package Push Upgrade Request failures after a push attempt, including grouping by important factors.
* Issue a terminal "Bell" sound and attempt to display a macOS notification when a commandline task or flow completes.
* Cleaned up python exception and error handling across the board, so that we can provide you, the user, with only the most relevant information. Try using CCI without setting your CUMULUSCI_KEY and see a simplified error message.
* Fixed the utils for processing namespaces in package zip files to handle non-ASCII characters
* The CONTRIBUTING.rst docs and Makefile have been updated to show how we release updates of CCI.
* Skip beta releases when checking for a newer cumulusci version
* When using the strip_namespace option on deployments, we now log which files had changes made before deploying.
* Going Out: the SFDXDeploy and SFDXJsonPollingTasks have been removed, as they didn't work.
* Going Out: Use the safe_load() method when loading YAML instead of the naive load(). If you relied on executing code in your CCI YAML file parsing, that will no longer work.

* Fixed apexdoc URL
* Fixed `update_admin_profile` to set any existing record type defaults to false before setting new defaults.
* Fixed deployment of -meta.xml files containing non-ASCII characters.
* Updated the robot selector for "Click Modal Button" to work for modals opened by a Quick Action.
