The MongoDB Database

The MSVC compiler has warnings which alert users that the behavior of the compiler has changed. In the case of C4383, the compiler used to have non-conforming behavior to C++98. At some point this behavior was fixed. MongoDB's code base should not have any code which would be adversely affected by this change, as the code is also compiled on platforms where the native compiler is conformant to the standard in this point. Therefore it should be safe to disable this warning. The specific warning cautions that a derived class's inline definition of a virtual function will now override a parent's implementation, where formerly it would not. This would happen when the derived class's implementation specified at least one of the parameters `const` (in such a way that the actual signature of the function isn't changed). MSVC incorrectly determines that if there are two functions that differ only in a non-observable `const` specifier, then they would have different signatures, in many circumstances. This would mean that the compiler resorts to treating such functions as overloads. The compiler now behaves correctly for the case of override in a derived class; however, it issues a warning. The warning is irrelevant to us. |

MongoDB README
Welcome to MongoDB!
COMPONENTS
mongod - The database server.
mongos - Sharding router.
mongo - The database shell (uses interactive javascript).
UTILITIES
mongodump - Create a binary dump of the contents of a database.
mongorestore - Restore data from the output created by mongodump.
mongoexport - Export the contents of a collection to JSON or CSV.
mongoimport - Import data from JSON, CSV or TSV.
mongofiles - Put, get and delete files from GridFS.
mongostat - Show the status of a running mongod/mongos.
bsondump - Convert BSON files into human-readable formats.
mongooplog - Poll the oplog and apply to a local server.
mongoreplay - Traffic capture and replay tool.
mongotop - Track time spent reading and writing data.
BUILDING
See docs/building.md.
RUNNING
For command line options invoke:
$ ./mongod --help
To run a single server database:
$ sudo mkdir -p /data/db
$ ./mongod
$
$ # The mongo javascript shell connects to localhost and test database by default:
$ ./mongo
> help
DRIVERS
Client drivers for most programming languages are available at
https://docs.mongodb.com/manual/applications/drivers/. Use the shell
("mongo") for administrative tasks.
BUG REPORTS
See https://github.com/mongodb/mongo/wiki/Submit-Bug-Reports.
PACKAGING
Packages are created dynamically by the package.py script located in the
buildscripts directory. This will generate RPM and Debian packages.
