Followup https://github.com/qgis/QGIS/pull/8830 that fixed
a regression with rewritten urls in the server, unfortunately
my original solution introduced a side-effect on the POST
request, with the new approach I'm introducing a new method
to retrieve the URL as seen by the web server: by default
this is the same URL seen by QGIS server, but in case
a rewrite module made some changes, the original URL will
be used as a base URL if not overridden by a config setting.
This PR comes with an extended set of tests that should
cover both (rewritten and unrewritten) cases for GET and
POST and for WFS/WFS/WCS and WMTS.
The previous behavior was to check if all parts of the collection are exactly the same.
The new check will check if all parts are equal (same vertice count, same vertice order, same vertice values).
This feature allows for expressions to be embedded directly inside
legend item text (e.g. group, subgroup and item text). The expressions
are evaluated at render time, with full knowledge of the legend's
expression context (so can utilise variables from the layout/layout item/
etc)
There's no UI for this yet (that will come in 3.8), but expressions are
entered using the standard [% 1 + 2 %] format.
E.g. a legend item text of
My layer (rendered at 1:[% @map_scale %])
will show in the output as
My layer (renderer at 1:1000)
Adds new variables for use in data defined expressions for layout legend items, including
- @legend_title
- @legend_column_count
- @legend_split_layers
- @legend_wrap_string
- @legend_filter_by_map
- @legend_filter_out_atlas
Additionally, if the legend is linked to a map, then expressions used in that legend will also have access to the linked variables, including @map_scale, @map_extent, etc.
In QGIS Server 3.4, the WMTS API has been added in which the tile matrices are calculated except fro EPSG:3857 and EPSG:4326.
This commit adds the capability to select the tile matrices to use with the project and to configure the top-left corner and the last level of the tile matrix. In the case of EPSG:3857 and EPSG:4326, the user can only choose the last level of the tile matrices.

has been linked to a project color
Instead of only showing linked color status in the accompanying
data defined button, we now also show it inside the color button
itself. So now the button color is a live reflection of the
project color it is linked to.
Additionally, when the color is linked, the button only allows
users the choice of "unlinking" the color from the linked
project color. The usual color button options allowing users
to directly change the color are not present. (As linked
colors must be edited in the project colors section from
the project properties dialog)
In OGC FilterEncoding standard, the PropertyIsLike element has an escapeChar attribute in place of escape attribute.
In the QgsOgcUtils class, the attribute escape or escapeChar is added to PropertyIsLike element, but it only checks escape attribute when it decodes it.
The commit fixed it and adds test.
Similarly to raster calculator, mesh calculator can take dataset groups from current mesh layer and
combine them with various aritmentic/logical operators to new dataset group.
Ports the similar algorithm from the shape tools plugin to c++, and utilises
built in QgsDistanceArea ellipsoidal calculations to split the lines.
This algorithm splits a line into multiple geodesic segments, whenever the
line crosses the antimeridian (±180 degrees longitude)
Splitting at the antimeridian helps the visual display of the lines in some
projections. The returned geometry will always be a multi-part geometry.
Whenever line segments in the input geometry cross the antimeridian,
they will be split into two segments, with the latitude of the breakpoint
being determined using a geodesic line connecting the points either side
of this segment. The current project ellipsoid setting will be used when
calculating this breakpoint.
If the input geometry contains M or Z values, these will be linearly
interpolated for the new vertices created at the antimeridian.
Supports in-place edit mode also.

This adds a new "Project Colors" section in data defined buttons
which are linked to a color value. The color menu contains all
colors defined as part of the current project's Project Color
Scheme (which is defined through project properties).
When a project color is selected from the button, the property
becomes linked to that color. It will automatically follow any
future changes to the color when made through project properties.
This allows users to define common colors for a project once,
and then "bind" symbol, label, layout, etc colors to these
preset colors. The link is live, so you change it once, and
the change is reflected EVERYWHERE. Sure beats updating a color
100 times when it's use has been scattered throughout a project's
symbols, labels, etc...
(Basically, this is just adding a shortcut to setting a data
defined expression "project_color(...)" for the property. The
project_color function has been around a LOOONG time, but it's
only really been usable by power users before this change)

- raise TypeError when these methods are called with incompatible
