Why does history indexing failure with -H cause the entire project index to fail in recent versions?

[Hatsuna-M1ku]

Hi,
In previous versions of OpenGrok, when I enabled the -H option to index history, even if the history indexing failed, the rest of the project (like source and xref indexing) would still be completed successfully.

However, in newer versions, it seems that if the history indexing fails, the entire indexing process for that project fails, and the project is not searchable at all.

Why was this behavior changed? Is there a way to make history indexing non-critical so that the rest of the indexing can still proceed even if history fails?

Thanks!

I think this is pretty well explained in the pertaining issue #4411

The option to suppress this behavior is documented in the release https://github.com/oracle/opengrok/releases/tag/1.12.21
