Segmentation Fault when loading data about bson-numpy

[amol-]

Problem seems to arise in field_order_match when comparing for _id:

(lldb) print next_key
(const char *) $3 = 0x0000000109568029 "_id"

The key is compared against one that has the right length (3 like "_id") but no valid value:

(lldb) print elem->key
(bsnp_string_t) $4 = (s = <no value available>, len = 3)

Thanks for the report! We're not able to devote much time to BSON-NumPy right now but we'll take a look soon. Would you like to submit a PR?

Sadly, as I'm not using this at work right now, I don't think I'll be able to find free time to fix it :/
This might be a pointer math issue and given I never used libbson before it might take some time to understand what's going on. I probably won't have free time for it in the next weeks.
I'll have a look from time to time when I have spare hours, if I come up with something I'll keep this issue updated and eventually submit a PR

Hi @amol- . I am closing this as we have discontinued development of BSON-NumPy. PyMongoArrow is now the recommended way to materialize MongoDB query results as NumPy ndarrays as well as tabular formats like Pandas' DataFrames and PyArrow Tables.

Note that PyMongoArrow does not segfault when attempting to load data that does not adhere to your specified schema. Instead, values that do not conform to the expected type are loaded as NaN's/Nulls.
