Not sure how this is supposed to work. To be able to support
Angular's development server and Spring as a standalone application
I had to hardcode the port Spring uses.
The problem is, that Angular runs on port 4200. Angular is compiled
to static files. So I cannot dynamically add the port that is
configured for Spring. But Angular has to be able to talk to the
Spring application.
I chose port 17333, because it does not collide with the standard
Tomcat port (8080).
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.
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.
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.
We do not know which fields exist at compile time.
But it is a great help to have some pre-selected
fields in groupBy.
Solved by adding a configuration option.
When using autocomplete to return field values I
missed, that autocomplete had the feature that cut
values at dots. So instead of returning full field
values only the prefix up to the first dot was
returned.
Fixed by making the cut-at-dot feature optional.
