Summary

mongoc_gridfs_file_set_id() does not work when the file has many chunks.

Environment

version: mongo-c-driver-1.21.0

host: debian 11 64-bit x86

gcc: gcc (Debian 10.2.1-6) 10.2.1 20210110

 

How to Reproduce

I use the example-gridfs tool to upload a big file, but the fs.files._id is not  as expected.

Then I upload a samll file, fs.files._id is as expected.

test> db.fs.files.find({})
[

{ _id: ObjectId("620cd61f9f63db1b8d012941"), chunkSize: 261120, filename: 'ss', length: Long("429273416"), uploadDate: ISODate("2022-02-16T10:46:55.642Z") }

,

{ _id: 1, chunkSize: 261120, filename: 'aa', length: Long("170027"), uploadDate: ISODate("2022-02-16T10:58:44.562Z") }

]
