UCESB cannot populate items in client_struct_info with client.setup

[YanzhaoW]

Describe the bug In the current version of ucesb (located at 'fake_cvmfs/10/cvmfs_fairroot_v18.8.0_fs_nov22p1_extra/ucesb'):

commit 7d684cda65d5f6ebb89db6848b19d24a6a47244c (origin/master, origin/HEAD, master)
Author: *****
Date:   Fri Nov 24 19:57:39 2023 +0100

The struct_info data from ucesb client can't populate its items after calling

ucesb_client_.setup(
                nullptr, 0, ucesb_client_struct_info_, &is_struct_map_success, event_struct_size_)

even it returns 0.

However it works with an older version:

commit a731f2582d6c322f2639a7c723d8e57ea205befb (HEAD -> master, origin/master, origin/HEAD)
Author: *****

To Reproduce

1. In R3BUcesbSource.cxx::156, change the code to

   Bool_t status = fClient.setup(NULL, 0, &fStructInfo, &struct_map_success, fEventSize);
   if (status != 0)
   { 
       .... 
   }
    for (auto* item = fStructInfo->_items; item != nullptr; item = item->_next_off_item)
   {
      std::cout << item->_var_name << "\n";
   }

2. Run any detector unpacking.
3. With the old version, all variable items can be printed out. With the new version, items are empty.

Additional context Sorry that I can't find anyone responsible for UCESB in volunteer list. Neither can I post this issue directly in UCESB Gitlab due to permission restrictions.

If it is an ucesb bug (separable / minimizable from r3broot and upexps), please try to join the group gitlab.com/chalmers-subexp and we see what can be done there.

Lack of volunteers should be referred to tech board, management board and collaboration board. They seem to not be clear on the jurisdiction, so I suggest to contact all at the same time, to avoid being bounced around.

Ok, great. I recreated this issue over there. I guess we could close it here.
