* Remove Application & Database dependency in PerfLog. Replace it with
a callback passed into the constructor.
* Fixes the circular dependency between ripple/nodestore and ripple/basics
If fast loading is enabled but the last persisted ledger is not
entirely on disk, the server would fail to start without manual
intervention by the server operator.
This commit allows the server to detect this scenario and attempt
to automatically recover.
This is a refactor aimed at cleaning up and simplifying the existing
job queue.
As of now, all jobs are cancelled at the same time and in the same
way, so this commit removes the per-job cancellation token. If the
need for such support is demonstrated, support can be re-added.
* Revise documentation for ClosureCounter and Workers.
* Simplify code, removing unnecessary function arguments and
deduplicating expressions
* Restructure job handlers to no longer need to pass a job's
handle to the job.
A typographical error would mishandle the case where a caller explicitly
tries to remove a child that is not actually part of the node. This case
is never invoked in practice, and so the bug would will never trigger.
Commit bf013c02ad added support
for incorporating a commit ID into the compiled version string
but did so in a way that did not follow the semantic versioning
standard.
This commit corrects that flaw by moving the commit ID into the
"metadata" part of the version string and properly handles the
case where the commit hash cannot be retrieved.
The pathfinding engine built into the code has several configurable
parameters to adjust the depth of the paths indexed and explored.
These parameters can dramatically impact the performance and memory
consumption of a server; higher values can result in resource usage
increasing exponentially.
These default values were decided early and somewhat arbitrarily at
a time when the network and the size of the network state were much
smaller.
This commit adjusts the default values to reduce the depth of paths
to more reasonable levels; unless explicitly overriden, the changes
mean that pathfinding operations will return fewer, shallower paths
than previous versions of the software.
This commit corrects a technical flaw that was introduced with commit
7c12f01358: as written, a mutex that is
intended to help provide synchronization for multiple threads as they
are each walking the map, is declared so that each thread is passed a
dangling reference to a unique mutex.
This commit hoists the mutex outside the thread creation loop, so all
threads use a single mutex and eliminating the dangling reference.
The nodestore includes a built-in cache to reduce the disk I/O
load but, by default, this cache was not initialized unless it
was explicitly configured by the server operator.
This commit introduces sensible defaults based on the server's
configured node size.
It remains possible to completely disable the cache if desired
by explicitly configuring it the cache size and age parameters
to 0:
[node_db]
...
cache_size = 0
cache_age = 0
