hgweb: add HTML elements to control whitespace settings for annotate...
hgweb: add HTML elements to control whitespace settings for annotate Building on top of the new URL query string arguments to control whitespace settings for annotate, this commit adds HTML checkboxes reflecting the values of these arguments to the paper and gitweb themes. The actual diff settings are now exported to the templating layer. The HTML templates add these as data-* attributes so they are accessible to the DOM. A new <form> with various <input> elements is added. The <form> is initially hidden via CSS. A shared JavaScript function (which runs after the <form> has been rendered but before the annotate HTML (because annotate HTML could take a while to load and we want the form to render quickly) takes care of setting the checked state of each box from the data-* attributes. It also registers an event handler to modify the URL and refresh the page whenever the checkbox state is changed. I'm using the URLSearchParams interface to perform URL manipulation. https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams tells me this may not be supported on older web browsers. Yes, apparently the web API didn't have a standard API to parse and format query strings until recently. Hence the check for the presence of this feature in the JavaScript. If the browser doesn't support the feature, the <form> will remain hidden and behavior will like it currently is. We could polyfill this feature or implement our own query string parsing. But I'm lazy and this could be done as a follow-up if people miss it. We could certainly expand this feature to support more diff options (such as lines of context). That's why the potentially reusable code is stored in a reusable place. It is also certainly possible to add diff controls to other pages that display diffs. But since Mozillians are making noise about controlling which revisions annotate shows, I figured I'd start there. .. feature:: Control whitespace settings for annotation on hgweb /annotate URLs on hgweb now accept query string arguments to influence how whitespace changes impact results. The arguments "ignorews," "ignorewsamount," "ignorewseol," and "ignoreblanklines" now have the same meaning as their [annotate] config section counterparts. Any provided setting overrides the server default. HTML checkboxes have been added to the paper and gitweb themes to expose current whitespace settings and to easily modify the current view.

Mercurial supports generating standalone "bundle" files that hold repository
data. These "bundles" are typically saved locally and used later or exchanged
between different repositories, possibly on different machines. Example
commands using bundles are :hg:`bundle` and :hg:`unbundle`.
Generation of bundle files is controlled by a "bundle specification"
("bundlespec") string. This string tells the bundle generation process how
to create the bundle.
A "bundlespec" string is composed of the following elements:
type
A string denoting the bundle format to use.
compression
Denotes the compression engine to use compressing the raw bundle data.
parameters
Arbitrary key-value parameters to further control bundle generation.
A "bundlespec" string has the following formats:
<type>
The literal bundle format string is used.
<compression>-<type>
The compression engine and format are delimited by a hyphen (``-``).
Optional parameters follow the ``<type>``. Parameters are URI escaped
``key=value`` pairs. Each pair is delimited by a semicolon (``;``). The
first parameter begins after a ``;`` immediately following the ``<type>``
value.
Available Types
===============
The following bundle <type> strings are available:
v1
Produces a legacy "changegroup" version 1 bundle.
This format is compatible with nearly all Mercurial clients because it is
the oldest. However, it has some limitations, which is why it is no longer
the default for new repositories.
``v1`` bundles can be used with modern repositories using the "generaldelta"
storage format. However, it may take longer to produce the bundle and the
resulting bundle may be significantly larger than a ``v2`` bundle.
``v1`` bundles can only use the ``gzip``, ``bzip2``, and ``none`` compression
formats.
v2
Produces a version 2 bundle.
Version 2 bundles are an extensible format that can store additional
repository data (such as bookmarks and phases information) and they can
store data more efficiently, resulting in smaller bundles.
Version 2 bundles can also use modern compression engines, such as
``zstd``, making them faster to compress and often smaller.
Available Compression Engines
=============================
The following bundle <compression> engines can be used:
.. bundlecompressionmarker
Examples
========
``v2``
Produce a ``v2`` bundle using default options, including compression.
``none-v1``
Produce a ``v1`` bundle with no compression.
``zstd-v2``
Produce a ``v2`` bundle with zstandard compression using default
settings.
``zstd-v1``
This errors because ``zstd`` is not supported for ``v1`` types.
