Major - P3 I have some data which we transformed into json so it can be imported into mongodb.
For some documents we need to have a date field that lies before 1970.
Here I document this issue simply with 1 millisecond before and after epoch.
We tested the documents by essentially doing this:
[nbasjes@localhost ~]$ echo 'db.datetest.save({"date": new Date(1)});' | mongo nielsbasjes
MongoDB shell version: 2.0.6
connecting to: nielsbasjes
bye
[nbasjes@localhost ~]$ echo 'db.datetest.save({"date": new Date(-1)});' | mongo nielsbasjes
MongoDB shell version: 2.0.6
connecting to: nielsbasjes
bye
and two documents have been inserted.
However when we try to load the same documents using mongoimport we get this:
[nbasjes@localhost ~]$ echo '{"date": new Date(1)}' | mongoimport -vv -d nielsbasjes -c datetest Thu Jun 21 17:43:19 creating new connection to:127.0.0.1 Thu Jun 21 17:43:19 BackgroundJob starting: ConnectBG Thu Jun 21 17:43:19 connected connection! connected to: 127.0.0.1 Thu Jun 21 17:43:19 ns: nielsbasjes.datetest Thu Jun 21 17:43:19 filesize: 0 Thu Jun 21 17:43:19 got line:{"date": new Date(1)} Thu Jun 21 17:43:19 got line: imported 1 objects
So far so good ...
[nbasjes@localhost ~]$ echo '{"date": new Date(-1)}' | mongoimport -vv -d nielsbasjes -c datetest Thu Jun 21 17:43:24 creating new connection to:127.0.0.1 Thu Jun 21 17:43:24 BackgroundJob starting: ConnectBG Thu Jun 21 17:43:24 connected connection! connected to: 127.0.0.1 Thu Jun 21 17:43:24 ns: nielsbasjes.datetest Thu Jun 21 17:43:24 filesize: 0 Thu Jun 21 17:43:24 got line:{"date": new Date(-1)} Thu Jun 21 17:43:24 Assertion: 10340:Failure parsing JSON string near: "date": ne 0x581a82 0x528610 0xaa3ff3 0xaa5e63 0xa9cccd 0xaa0932 0x3bbb81ecdd 0x4fed69 mongoimport(_ZN5mongo11msgassertedEiPKc+0x112) [0x581a82] mongoimport(_ZN5mongo8fromjsonEPKcPi+0x3d0) [0x528610] mongoimport(_ZN6Import8parseRowEPSiRN5mongo7BSONObjERi+0x8b3) [0xaa3ff3] mongoimport(_ZN6Import3runEv+0x16e3) [0xaa5e63] mongoimport(_ZN5mongo4Tool4mainEiPPc+0x169d) [0xa9cccd] mongoimport(main+0x32) [0xaa0932] /lib64/libc.so.6(__libc_start_main+0xfd) [0x3bbb81ecdd] mongoimport(__gxx_personality_v0+0x3c9) [0x4fed69] exception:Failure parsing JSON string near: "date": ne Thu Jun 21 17:43:24 got line: imported 0 objects encountered 1 error
We have tried several syntaxes for the same date and we get the same effect with all these forms:
- {"date": new Date(-2174520376)}
- {"date": new Date(1901,2,3,22,33,44,000)}
- {"date": new Date("February 3, 1901 22:33:44")
