TTree GetEntry memory problem

[bressan]

Dear Philippe,
ACL for those directory are fine, but I forgot to ask for the “list” rights on upper dirs.
I pass the information and let you know when done.

cheers,
Andrea

PS: acl’s for rootprobs are hereafter.

Thanks. I can read the file and reproduce the problem (abeit only with 6.18/04 so I am now verifying if we really fixed and if so when).

@bressan

I’ve check the compression level for that root tree and is ==1.

Argg … I did not pay enough attention to your answer and/or got confused by it.

When looking at your file, I see that the compression ratio is 1.0 … i.e no compression and indeed the file compression level is 0:

$ root.exe -b -l rd_p09mup_s5_bs2_excl.root 
root [0] 
Attaching file rd_p09mup_s5_bs2_excl.root as _file0...
(TFile *) 0x299b1c0
root [1] gFile->GetCompressionLevel()
(int) 0

Which means (and confirm by bisect …) that the commit (2d46e97fbd5ef8870cda394943f1f1f6aa784527) I have talking about is solving the problem.

This is fixed in v6.18/06 (not released yet) and in v6.20 and later.

Cheers,
Philippe.

Dear Philippe,
In my mind compression 1 was meant as no compression;
I took that info by printing the tree, not by accessing with the getcompressionlevel method.

Thanks for your help on this issue.
