Packing and Unpacking Data

[Praneeth]

Hi,

I am trying to experiment  with packing and unpacking data, in particular the behaviour detailed here: WiredTiger: Packing and Unpacking Data

I want to store the keys in a big-endian, standard representation, but when I add '>' at the beginning of my key_format string (in the ex_pack.c example):

         error_check(wiredtiger_struct_size(session, &size, ">iii", 42, 1000, -9));
         if (size > sizeof(buf)) {
             /* Allocate a bigger buffer. */
         }

I get the following error: 

ex_pack: FAILED: main/55: wiredtiger_struct_size(session, &size, ">iii", 42, 1000, -9): Invalid argument
ex_pack: process aborting
WiredTiger Error: __wt_abort, 28: aborting WiredTiger library
Aborted (core dumped)

What am I doing wrong here? I'd really appreciate some help. 

Thanks

Praneeth

Hi Praneeth,

Thank you for your interest in WiredTiger and how packing and unpacking work. I could reproduce the error and I have filed WT-10235 (I will add details to the ticket soon), feel free to subscribe to it to get updates. The team will work on it as soon as possible. Sorry for the inconvenience.
