I do not know the sizes of the previous weekends run, since we do not keep the coverage dbs, but since nothing else changed in the procedure, i assume that 2GB is the problem here.</p>

    1. COThe coverage data is actually 2Gb?? How big is the software system being tested (SLOC)? I'd expect it to be several hundred million bytes worst case if you had 100 million lines of code, based on raw information demand (not on any specific knowledge of clover). What's in there besides raw coverage information?

    2. CO@Anthony: I tried accessing the 3 cloverdb databases before merging, which works, then i tried accessing the merged one, which did not work anymore. The file resulting from merging the 3 files actually IS just over 2 GB large.

    3. CO@Ira: The project i run coverage on is around 1Mio lines of code. I have per-test coverage turned on (we need that), and this does not result from a single testrun, but from 60-80 runs. Those are client tests, integration tests and unit tests, and they are run on multiple platforms with different setups on each run. The size has always been in the range around that and was continously growing. Now it hit 2GB.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
