Hi Christian, My static-check.pl script has pinged me about the get_delta_base() symbol from packfile.[co]. The first patch from your 'cc/delta-islands' branch exports this symbol, saying that it will soon be called from outside packfile.c. As far as I can tell, no other patch in that series adds any such call. Do you have plans to extend that series with additional patches which will add such calls? ATB, Ramsay Jones
