Hi,
Starting recently (probably from ROOT 3.10-01) we have started to see
R__unzip errors in reading back tree branches containing only integers. It
is a bit complicated so I've not yet succeeded in reducing it to a simple
test case, but I already see something strange in looking at a file:
*............................................................................*
*Br 19 :Emc_Bumps__n : Emc_Bumps__n/i *
*Entries : 6000 : Total Size= 36446 bytes One basket in memory *
*Baskets : 0 : Basket Size= 32000 bytes Compression= 1.00 *
*............................................................................*
*Br 21 :Emc_Clusters__n : Emc_Clusters__n/i *
*Entries : 6000 : Total Size= 36464 bytes One basket in memory *
*Baskets : 0 : Basket Size= 32000 bytes Compression= 1.00 *
*............................................................................*
*Br 23 :Emc_Cands__n : Emc_Cands__n/i *
*Entries : 6000 : Total Size= 36446 bytes One basket in memory *
*Baskets : 0 : Basket Size= 32000 bytes Compression= 1.00 *
*............................................................................*
Is it normal that the total size would exceed the basket size yet a basket
is not compressed and written separately from the tree?
I recall that you put in some bug fix recently related to compression of
branches containing integers, could you remind me what was that fix?
[For the record, we are working on Linux (RH7.2) with gcc 2.95.3.]
thanks,
Pete
