v0.4.0-alpha.2 2019-12-23

Fixes

  • Fix docs

v0.4.0-alpha.1 2019-12-23

Refactored most of the code, but it was all tested. I'm sorry, some API changes, but in exchange for better experience and performance.

Changes

  • ConnectionManager is changed to Manager and simplified.
    • get_executor are removed.
    • has_broken are removed.
    • is_valid to check
    • Add a provided method spawn_task. You might use it when using mobc in runtimes other than tokio-0.2 and async-std.
  • The connection pool now initializes without creating a new database connection, which saves a lot of time and resources. So it becomes a synchronization API.
  • Pool.state() will now return more detailed statistics.
  • Some configuration items are changed.
    • min_idle to max_idle, which means that idle connections over this number will be closed
    • max_size to max_open. If you set it to 0, the pool will create unlimited new connections if necessary. However, these connections are still limited by max_idle when idle
  • Pool.try_get are removed.

v0.3.3 2019-12-23

Fixes

  • Fix Connection recycle.
  • Panics if min_idle is 0

v0.3.2 2019-12-10

Fixes

  • Timeout caused by reaping

v0.2.11 2019-12-10

Fixes

  • Timeout caused by reaping

v0.3.1 2019-12-05

Fixes

  • Documentation of mobc::Builder
