The old method of creating brighter/darker colors was producing color
shades that did not look like the same color. E.g. a darker yellow
looked more like brown.
I am now trying to use hand crafted shades.
The drop down for plot types should only contain plot types that can
be combined. The reason is, that we can only draw images with two
x/y-axis. Therefore a combination of types that would need three or more
axis is not supported.
The writerCache in DataStore did not use the partitionId
in its cache key. Therefore the cache could return the
wrong writer and events were written to the wrong
partition.
Fixed by changing the cache key.
To make it easier/possible to write stable unit test the CSV upload
can optionally wait until all entries have been flushed to disk.
This is necessary for tests that ingest data and then read the data.
We want to be able to use @SpringBootTest tests that fully initialize
the Spring application. This is much easier done with Junit than TestNG.
Gradle does not support (at least not easily) to run Junit and TestNG
tests. Therefore we switch to Junit with all tests.
The original reason for using TestNG was that Junit didn't support
data providers. But that finally changed in Junit5 with
ParameterizedTest.
Recommind is using a pseudo ISO date format for their
log files. It uses a comma instead of a dot for the
second to milli second separator and it does not
add a timezone. Dates without timezone are assumed to be UTC.
Refactoring to prepare the addition of CSV parsing rules. The parsing
rules will contain information about which columns to ingest or ignore.
This will be used to add the ability to upload files via HTTP post in
addition to the TcpIngestor.
The icons were made with Inkscape. This tool does not care
for file size. By rewriting the icons by hand I could reduce
the file size siginificantly. E.g. 6.1kb to 441 bytes for
cumulative-distribution-chart.svg.
Classpathes in Eclipse are different from classpathes in Gradle due to
Gradle's 'implementation' configuration which does not provide
dependency transitively in Gradle.
Remove the controller method that returned the VueJS index page.
Add resource handlers that redirect to the Angular application.
I added two implementations, but activated only one. At the moment I am
not sure which solution is the better. We keep both so that we can
easily switch if need arises.
Generating all images for a gallery view can take
long. It might not be obvious when the computation
is done, because there is no progress indicator.
Fixed by adding a progress bar.
You might want to abort the computation. E.g.
because you already found what you were looking
for or you want to change the parameters.
This can now be done by clicking 'Abort'.
Note, it does not abort the current computation.
In the previous changeset the code that determined
which axis the plots used was implemented as a
side effect of getting the Gnuplot definition of
an axis.
Changed that to an explit update call with simpler
logic.
