06:50 sten rurban hi
06:50 sten thx for fixes for Internals::DumpArenas
06:53 sten I used it to analyze mem growing in my project, I investigated that it grow because count NULL SVs constantly increasing. They looks like this in dump:
06:53 sten SV = NULL(0x0) at 0x7f989f6fd860
06:53 sten REFCNT = 1
06:53 sten FLAGS = ()
06:53 sten we can see that refcnt is 1, but I can't found anywhere ref to addr 0x7f989f6fd860
06:54 sten what it could be? why perl hold it?
06:57 sten after 2 hours of script running it have >5kk NULL SVs
07:00 sten update: 90% of NULL SVs have FLAGS = (PADTMP)
07:26 rurban 0x7f989f6fd860 is just the address of this NULL SV
07:26 rurban Those are all lexicals which where never written to or went out of scope
07:27 rurban perl has to reserve space for lexicals even when they are not assigned

13:36 sten rurban, what may cause huge value(>1000000) of SV = NULL without reference? some leak in XS?
