+# Configuring Azure Pipelines with Certbot
+
+Let's begin. All pipelines are defined in `.azure-pipelines`. Currently there are two:
+* `.azure-pipelines/main.yml` is the main one, executed on PRs for master, and pushes to master,
+* `.azure-pipelines/advanced.yml` add installer testing on top of the main pipeline, and is executed for `test-*` branches, release branches, and nightly run for master.
+
+Several templates are defined in `.azure-pipelines/templates`. These YAML files aggregate common jobs configuration that can be reused in several pipelines.
+
+Unlike Travis, where CodeCov is working without any action required, CodeCov supports Azure Pipelines
+using the coverage-bash utility (not python-coverage for now) only if you provide the Codecov repo token
+using the `CODECOV_TOKEN` environment variable. So `CODECOV_TOKEN` needs to be set as a secured
+environment variable to allow the main pipeline to publish coverage reports to CodeCov.
+
+This INSTALL.md file explains how to configure Azure Pipelines with Certbot in order to execute the CI/CD logic defined in `.azure-pipelines` folder with it.
+During this installation step, warnings describing user access and legal comitments will be displayed like this:
+```
+!!! ACCESS REQUIRED !!!
+```
+
+This document suppose that the Azure DevOps organization is named _certbot_, and the Azure DevOps project is also _certbot_.

+* https://docs.microsoft.com/en-us/azure/devops/pipelines/ecosystems/python?view=azure-devops
+
+## Prerequisites
+
+### Having a GitHub account
+
+Use your GitHub user for a normal GitHub account, or a user that has administrative rights to the GitHub organization if relevant.
+
+### Having an Azure DevOps account
+- Go to https://dev.azure.com/, click "Start free with GitHub"
+- Login to GitHub
+
+```
+!!! ACCESS REQUIRED !!!
+Personal user data (email + profile info, in read-only)
+```
+
+- Microsoft will create a Live account using the email referenced for the GitHub account. This account is also linked to GitHub account (meaning you can log it using GitHub authentication)
+- Proceed with account registration (birth date, country), add details about name and email contact
+
+```
+!!! ACCESS REQUIRED !!!
+Microsoft proposes to send commercial links to this mail
+Azure DevOps terms of service need to be accepted
+```
+
+_Logged to Azure DevOps, account is ready._
+
+### Installing Azure Pipelines to GitHub
+
+- On GitHub, go to Marketplace
+- Select Azure Pipeline, and "Set up a plan"
+- Select Free, then "Install it for free"
+- Click "Complete order and begin installation"
+
+```
+!!! ACCESS !!!
+Azure Pipeline needs RW on code, RO on metadata, RW on checks, commit statuses, deployments, issues, pull requests.
+RW access here is required to allow update of the pipelines YAML files from Azure DevOps interface, and to
+update the status of builds and PRs on GitHub side when Azure Pipelines are triggered.
+Note however that no admin access is defined here: this means that Azure Pipelines cannot do anything with
+protected branches, like master, and cannot modify the security context around this on GitHub.
+Access can be defined for all or only selected repositories, which is nice.
+```
+
+- Redirected to Azure DevOps, select the account created in _Having an Azure DevOps account_ section.
+- Select the organization, and click "Create a new project" (let's name it the same than the targetted github repo)
+- The Visibility is public, to profit from 10 parallel jobs
+
+```
+!!! ACCESS !!!
+Azure Pipelines needs access to the GitHub account (in term of beeing able to check it is valid), and the Resources shared between the GitHub account and Azure Pipelines.
+```
+
+_Done. We can move to pipelines configuration._
+
+## Import an existing pipelines from `.azure-pipelines` folder
+
+- On Azure DevOps, go to your organization (eg. _certbot_) then your project (eg. _certbot_)
+- Click "Pipelines" tab
+- Click "New pipeline"
+- Where is your code?: select "__Use the classic editor__"
+
+__Warning: Do not choose the GitHub option in Where is your code? section. Indeed, this option will trigger an OAuth
+grant permissions from Azure Pipelines to GitHub in order to setup a GitHub OAuth Application. The permissions asked
+then are way too large (admin level on almost everything), while the classic approach does not add any more
+permissions, and works perfectly well.__
+
+- Select GitHub in "Select your repository section", choose certbot/certbot in Repository, master in default branch.
+- Click on YAML option for "Select a template"
+- Choose a name for the pipeline (eg. test-pipeline), and browse to the actual pipeline YAML definition in the
+  "YAML file path" input (eg. `.azure-pipelines/test-pipeline.yml`)
+- Click "Save & queue", choose the master branch to build the first pipeline, and click "Save and run" button.
+
+_Done. Pipeline is operational. Repeat to add more pipelines from existing YAML files in `.azure-pipelines`._
+
+## Add a secret variable to a pipeline (like `CODECOV_TOKEN`)
+
+__NB: Following steps suppose that you already setup the YAML pipeline file to
+consume the secret variable that these steps will create as an environment variable.
+For a variable named `CODECOV_TOKEN` consuming the variable `codecov_token`,
+in the YAML file this setup would take the form of the following:
+```
+steps:
+    - script: ./do_something_that_consumes_CODECOV_TOKEN  # Eg. `codecov -F windows`
+      env:
+        CODECOV_TOKEN: $(codecov_token)
+```
+
+To set up a variable that is shared between pipelines, follow the instructions
+at
+https://docs.microsoft.com/en-us/azure/devops/pipelines/library/variable-groups.
+When adding variables to a group, don't forget to tick "Keep this value secret"
+if it shouldn't be shared publcily.

-
-Certbot is part of EFF’s effort to encrypt the entire Internet. Secure communication over the Web relies on HTTPS, which requires the use of a digital certificate that lets browsers verify the identity of web servers (e.g., is that really google.com?). Web servers obtain their certificates from trusted third parties called certificate authorities (CAs). Certbot is an easy-to-use client that fetches a certificate from Let’s Encrypt—an open certificate authority launched by the EFF, Mozilla, and others—and deploys it to a web server.
-
-Anyone who has gone through the trouble of setting up a secure website knows what a hassle getting and maintaining a certificate is. Certbot and Let’s Encrypt can automate away the pain and let you turn on and manage HTTPS with simple commands. Using Certbot and Let's Encrypt is free, so there’s no need to arrange payment.
-
-How you use Certbot depends on the configuration of your web server. The best way to get started is to use our `interactive guide <https://certbot.eff.org>`_. It generates instructions based on your configuration settings. In most cases, you’ll need `root or administrator access <https://certbot.eff.org/faq/#does-certbot-require-root-administrator-privileges>`_ to your web server to run Certbot.
-
-Certbot is meant to be run directly on your web server, not on your personal computer. If you’re using a hosted service and don’t have direct access to your web server, you might not be able to use Certbot. Check with your hosting provider for documentation about uploading certificates or using certificates issued by Let’s Encrypt.
-
-Certbot is a fully-featured, extensible client for the Let's
-Encrypt CA (or any other CA that speaks the `ACME
-<https://github.com/ietf-wg-acme/acme/blob/master/draft-ietf-acme-acme.md>`_
-protocol) that can automate the tasks of obtaining certificates and
-configuring webservers to use them. This client runs on Unix-based operating
-systems.
-
-To see the changes made to Certbot between versions please refer to our
-`changelog <https://github.com/certbot/certbot/blob/master/CHANGELOG.md>`_.
-
-Until May 2016, Certbot was named simply ``letsencrypt`` or ``letsencrypt-auto``,
-depending on install method. Instructions on the Internet, and some pieces of the
-software, may still refer to this older name.

-Current Features
-=====================
-
-* Supports multiple web servers:
-
-  - apache/2.x
-  - nginx/0.8.48+
-  - webroot (adds files to webroot directories in order to prove control of
-    domains and obtain certs)
-  - standalone (runs its own simple webserver to prove you control a domain)
-  - other server software via `third party plugins <https://certbot.eff.org/docs/using.html#third-party-plugins>`_
-
-* The private key is generated locally on your system.
-* Can talk to the Let's Encrypt CA or optionally to other ACME
-  compliant services.
-* Can get domain-validated (DV) certificates.
-* Can revoke certificates.
-* Adjustable RSA key bit-length (2048 (default), 4096, ...).
-* Can optionally install a http -> https redirect, so your site effectively
-  runs https only (Apache only)
-* Fully automated.
-* Configuration changes are logged and can be reverted.
-* Supports an interactive text UI, or can be driven entirely from the
-  command line.
-* Free and Open Source Software, made with Python.

+"""
+Augeas implementation of the ParserNode interfaces.
+
+Augeas works internally by using XPATH notation. The following is a short example
+of how this all works internally, to better understand what's going on under the
+hood.
+
+A configuration file /etc/apache2/apache2.conf with the following content:
+
+    # First comment line
+    # Second comment line
+    WhateverDirective whatevervalue
+    <ABlock>
+        DirectiveInABlock dirvalue
+    </ABlock>
+    SomeDirective somedirectivevalue
+    <ABlock>
+        AnotherDirectiveInABlock dirvalue
+    </ABlock>
+    # Yet another comment
+
+
+Translates over to Augeas path notation (of immediate children), when calling
+for example: aug.match("/files/etc/apache2/apache2.conf/*")
+
+[
+    "/files/etc/apache2/apache2.conf/#comment[1]",
+    "/files/etc/apache2/apache2.conf/#comment[2]",
+    "/files/etc/apache2/apache2.conf/directive[1]",
+    "/files/etc/apache2/apache2.conf/ABlock[1]",
+    "/files/etc/apache2/apache2.conf/directive[2]",
+    "/files/etc/apache2/apache2.conf/ABlock[2]",
+    "/files/etc/apache2/apache2.conf/#comment[3]"
+]
+
+Regardless of directives name, its key in the Augeas tree is always "directive",
+with index where needed of course. Comments work similarly, while blocks
+have their own key in the Augeas XPATH notation.
+
+It's important to note that all of the unique keys have their own indices.
+
+Augeas paths are case sensitive, while Apache configuration is case insensitive.
+It looks like this:
+
+    <block>
+        directive value
+    </block>
+    <Block>
+        Directive Value
+    </Block>
+    <block>
+        directive value
+    </block>
+    <bLoCk>
+        DiReCtiVe VaLuE
+    </bLoCk>
+
+Translates over to:
+
+[
+    "/files/etc/apache2/apache2.conf/block[1]",
+    "/files/etc/apache2/apache2.conf/Block[1]",
+    "/files/etc/apache2/apache2.conf/block[2]",
+    "/files/etc/apache2/apache2.conf/bLoCk[1]",

+"""ParserNode interface for interacting with configuration tree.
+
+General description
+-------------------
+
+The ParserNode interfaces are designed to be able to contain all the parsing logic,
+while allowing their users to interact with the configuration tree in a Pythonic
+and well structured manner.
+
+The structure allows easy traversal of the tree of ParserNodes. Each ParserNode
+stores a reference to its ancestor and immediate children, allowing the user to
+traverse the tree using built in interface methods as well as accessing the interface
+properties directly.
+
+ParserNode interface implementation should stand between the actual underlying
+parser functionality and the business logic within Configurator code, interfacing
+with both. The ParserNode tree is a result of configuration parsing action.
+
+ParserNode tree will be in charge of maintaining the parser state and hence the
+abstract syntax tree (AST). Interactions between ParserNode tree and underlying
+parser should involve only parsing the configuration files to this structure, and
+writing it back to the filesystem - while preserving the format including whitespaces.
+
+For some implementations (Apache for example) it's important to keep track of and
+to use state information while parsing conditional blocks and directives. This
+allows the implementation to set a flag to parts of the parsed configuration
+structure as not being in effect in a case of unmatched conditional block. It's
+important to store these blocks in the tree as well in order to not to conduct
+destructive actions (failing to write back parts of the configuration) while writing
+the AST back to the filesystem.
+
+The ParserNode tree is in charge of maintaining the its own structure while every
+child node fetched with find - methods or by iterating its list of children can be
+changed in place. When making changes the affected nodes should be flagged as "dirty"
+in order for the parser implementation to figure out the parts of the configuration
+that need to be written back to disk during the save() operation.
+
+
+Metadata
+--------
+
+The metadata holds all the implementation specific attributes of the ParserNodes -
+things like the positional information related to the AST, file paths, whitespacing,
+and any other information relevant to the underlying parser engine.
+
+Access to the metadata should be handled by implementation specific methods, allowing
+the Configurator functionality to access the underlying information where needed.
+
+For some implementations the node can be initialized using the information carried
+in metadata alone. This is useful especially when populating the ParserNode tree
+while parsing the configuration.
+
+
+Apache implementation
+---------------------
+
+The Apache implementation of ParserNode interface requires some implementation
+specific functionalities that are not described by the interface itself.
+
+Initialization
+
+When the user of a ParserNode class is creating these objects, they must specify
+the parameters as described in the documentation for the __init__ methods below.
+When these objects are created internally, however, some parameters may not be
+needed because (possibly more detailed) information is included in the metadata
+parameter. In this case, implementations can deviate from the required parameters
+from __init__, however, they should still behave the same when metadata is not
+provided.
+
+For consistency internally, if an argument is provided directly in the ParserNode
+initialization parameters as well as within metadata it's recommended to establish
+clear behavior around this scenario within the implementation.
+
+Conditional blocks
+
+Apache configuration can have conditional blocks, for example: <IfModule ...>,
+resulting the directives and subblocks within it being either enabled or disabled.
+While find_* interface methods allow including the disabled parts of the configuration
+tree in searches a special care needs to be taken while parsing the structure in
+order to reflect the active state of configuration.
+
+Whitespaces
+
+Each ParserNode object is responsible of storing its prepending whitespace characters
+in order to be able to write the AST back to filesystem like it was, preserving the
+format, this applies for parameters of BlockNode and DirectiveNode as well.
+When parameters of ParserNode are changed, the pre-existing whitespaces in the
+parameter sequence are discarded, as the general reason for storing them is to
+maintain the ability to write the configuration back to filesystem exactly like
+it was. This loses its meaning when we have to change the directives or blocks
+parameters for other reasons.
+
+Searches and matching
+
+Apache configuration is largely case insensitive, so the Apache implementation of
+ParserNode interface needs to provide the user means to match block and directive
+names and parameters in case insensitive manner. This does not apply to everything
+however, for example the parameters of a conditional statement may be case sensitive.
+For this reason the internal representation of data should not ignore the case.

+    ParserNode is the basic building block of the tree of such nodes,
+    representing the structure of the configuration. It is largely meant to keep
+    the structure information intact and idiomatically accessible.
+
+    The root node as well as the child nodes of it should be instances of ParserNode.
+    Nodes keep track of their differences to on-disk representation of configuration
+    by marking modified ParserNodes as dirty to enable partial write-to-disk for
+    different files in the configuration structure.
+
+    While for the most parts the usage and the child types are obvious, "include"-
+    and similar directives are an exception to this rule. This is because of the
+    nature of include directives - which unroll the contents of another file or
+    configuration block to their place. While we could unroll the included nodes
+    to the parent tree, it remains important to keep the context of include nodes
+    separate in order to write back the original configuration as it was.
+
+    For parsers that require the implementation to keep track of the whitespacing,
+    it's responsibility of each ParserNode object itself to store its prepending
+    whitespaces in order to be able to reconstruct the complete configuration file
+    as it was when originally read from the disk.

+    # object resides. For root node, the value for filepath is the httpd root
+    # configuration file. Filepath can be None if a configuration directive is
+    # defined in for example the httpd command line.
