be shown to users when using that provider
This can be used to return a translated warning message which should be
shown to users of this provider. It's intended for use in cases such as
a provider which relies on a 3rd-party backend, where the version of the
backend software is not officially supported, or for alerting users to
providers in a "beta" or "untrustworthy" state.
always avoid using temporary file names, and then set this option as
enabled by default.
Also change the setting key so that existing users will also get the new
default value.
Fixes#32591
output format
This setting is still used and required in some circumstances, e.g.
it is used as the default selection in outputs file pickers when
the previously used format is not valid.
each new algorithm execution
Avoids the situation where errors reported during an algorithm
which was overall successully executed are append to the errors
for later execution steps
Instead, record errors and report them all at the end of the batch
process. If we abort the remaining batch steps when encountering any
error, this blocks a useful use of the batch mode and prevents users
from running a batch process over a large number of input files, some
of which may be invalid.
And:
- fix enable state of selected features only after changing between
map layers with/without selections
- fix state of selected features only when running an algorithm
from the history list, e.g. respect original setting for
selected features only (or not)
- ensure no duplicate changed signals are sent, and correctly
emit changed signals in all applicable circumstances
- handle drag and dropped layers from browser panel (UX fix)
- soak with unit tests
Include the input parameter values in the report, otherwise the
results are just a meaningless list of values which can't be
associated with any particular set of inputs
Also correctly handle boolean and other output types
In processing, if an algorithm has a boolean as an output, it cannot be defined as boolean but as a number.
To be more precise in algorithms description, the commit add QgsProcessingOutputBoolean.
populating batch processing dialog
This option adds news rows using the values from an expression
which returns an array. (As opposed to "Calculate by Expression",
which works only on existing rows).
The intended use case is to allow populating the batch dialog
using complex numeric series, e.g. those created by the "generate_series"
expression function.
For example, adding rows for a batch buffer using the expression
generate_series(100, 1000, 50)
(results in new rows with values 100, 150, 200, .... 1000)
This new option is available under the Autofill menu for a column. Selecting it allows users
to create a new QGIS expression to use to update the value inside that column. Existing
parameter values (including those from other columns) are available for use inside
the expression via @variables.
E.g. this allows setting output file names to complex expressions like
'/home/me/stuff/buffer_' || left(@input, 30) || '_' || @distance || '.shp'
