    Fix issue where the wrong pid was being stored in the list of monitors

    Vagabond authored
    When a pid exited while the pool was full and there were blocking
    checkouts, poolboy would put the pid of the process requesting a worker
    in the monitor tuple along with the monitor ref, instead of the pid of
    the worker.

    Add a parallel property for poolboy

    Vagabond authored
    To trigger some of the more interesting code, we need to truly do things
    in parallel, so blocking checkouts can actually happen while other
    requests are being made. This commit adds a parallel property for
    poolboy, based on the original serial one.
    
    One hack that was needed was to add a trailing call to erlang:self() to
    the end of each parallel branch so that we could filter out workers
    checked out by that particular branch from the model. This is necessary
    because poolboy monitors the process holding the worker and will destroy
    any workers held by a process and re-start them, if necessary, to
    maintain the right number of workers in the pool. This filtering is done
    in the next_state command, and all elements in the checked_out list in
    the model are tuples of {Worker, self()} so the list can be filtered.
    
    Happily, although this exercises more core, no additional bugs were
    found.

    Checkin non-worker processes 10% of the time and fix resulting bugs

    Vagabond authored
    Checking in an invalid process corrupts the internal state similarly to
    receiving EXITs from non-worker pids.

    Add command to send poolboy EXIT messages for unrelated pids; fix bugs

    Vagabond authored
    Sending poolboy EXIT messages for pids that are not workers causes
    invalid changes to poolboy's state. Also, legitimate processes dying
    after being checked back in also would corrupt the internal state. Add
    better checking in the EXIT handling code to guard against this.

    Add command to kill workers after they're checked back in, and fix bugs

    Vagabond authored
    Extend the 'status' to check the number of monitors poolboy has on
    processes that have checked out workers. When a process dies after being
    checked back in, poolboy zeroes out the list of monitors for some reason.

    Add kill_worker and fix resulting bugs

    Vagabond authored
    kill_worker exposed some new faults in poolboy, where the maximum size
    of the pool could end up smaller than it should be after a worker was
    killed.
    
    To help in debugging this, a 'status' command was added to poolboy to
    look at its internal state and a dynamic_precondition function was used
    to compare the expected state to the actual state.
    
    Numerous problems were discovered by doing this, poolboy had issues
    around when it changed states, like allocating the last non-overflow
    worker would leave the pool in 'ready' until the next request came in,
    instead of immediately changing the state.

    Add blocking checkout to quickcheck test and fix poolboy bug

    Vagabond authored
    The bug discovered was that blocking checkouts that had expired were not
    being removed from the list of 'waiting' checkouts, so when a checkout
    had timed out and a worker was subsequently checked in, the new worker
    would be sent to the expired checkout request, not any current ones.

    Initial quickcheck test for poolboy

    For now, only test the simplest API; start, stop, checkout nonblocking
    and checkin.

  1. Added init and stop funs to poolboy's config

    Kevin Smith authored
    Added init_fun and stop_fun to poolboy's config proplist.
    These functions are used to init and stop workers as they're
    added and removed from a pool. These functions allow poolboy
    to pool processes which need additional processing before they
    are ready to be added or removed from the pool.
    
    The motivation for adding these functions is the case where poolboy
    is managing a pool of database connection processes. These processes
    need to load prepared statements immediately after they are created
    and before they are placed in the pool. Prior to adding these functions
    the only way to pool these processes was to wrap them in additional code
    to handle the post-connection initialization. These functions now
    permit poolboy to pool the database connections without wrapping them.

    Some people value the let-it-fail philosophy which would allow the pool to fail when it can't send the event in time. Others may want to mimic a wholly blocking interface with infinity.
