# Changes in version 2.1.1.0
|
|
|
|
|
|
|
|
* Adds feature to track outgone datasource fetches. This is only turned on
|
|
|
|
for report level greater than 1. The fetches are stored as a running Map
|
|
|
|
in the env ('submittedReqsRef').

# Changes in version 2.1.0.0
|
|
|
|
|
|
|
|
* Add a new 'w' parameter to 'GenHaxl' to allow arbitrary writes during
|
|
|
|
a computation. These writes are stored as a running log in the Env,
|
|
|
|
and are not memoized. This allows users to extract information from
|
|
|
|
a Haxl computation which throws. Our advise is to limit these writes to
|
|
|
|
monitoring and debugging logs.
|
|
|
|
|
|
|
|
* A 'WriteTree' constructor to maintain log of writes inside the Environment.
|
|
|
|
This is defined to allow O(1) mappend.

# Changes in version 2.0.0.0
|
|
|
|
|
|
|
|
* Completely rewritten internals to support arbitrarily overlapping
|
|
|
|
I/O and computation. Haxl no longer runs batches of I/O in
|
|
|
|
"rounds", waiting for all the I/O to complete before resuming the
|
|
|
|
computation. In Haxl 2, we can spawn I/O that returns results in
|
|
|
|
the background and computation fragments are resumed when the
|
|
|
|
values they depend on are available. See
|
|
|
|
`tests/FullyAsyncTest.hs` for an example.
|
|
|
|
|
|
|
|
* A new `PerformFetch` constructor supports the new concurrency
|
|
|
|
features: `BackgroundFetch`. The data source is expected to call
|
|
|
|
`putResult` in the background on each `BlockedFetch` when its
|
|
|
|
result is ready.
|
|
|
|
|
|
|
|
* There is a generic `DataSource` implementation in
|
|
|
|
`Haxl.DataSource.ConcurrentIO` for performing each I/O operation
|
|
|
|
in a separate thread.
|
|
|
|
|
|
|
|
* Lots of cleanup and refactoring of the APIs.

|
|
* 'pAnd' and 'pOr' were added
|
|
|
|
* 'asyncFetchAcquireRelease' was added
|
|
|
|

# Changes in version 0.5.0.0
|
|
|
|
* Rename 'Show1' to 'ShowP' ([#62](https://github.com/facebook/Haxl/issues/62))

# Changes in version 0.3.0.0
|
|
|
|
|
|
|
|
* Some performance improvements, including avoiding quadratic
|
|
|
|
slowdown with left-associated binds.
|
|
|
|
|
|
|
|
* Documentation cleanup; Haxl.Core is the single entry point for the
|
|
|
|
core and engine docs.
|
|
|
|
|
|
|
|
* (>>) is now defined to be (*>), and therefore no longer forces
|
|
|
|
sequencing. This can have surprising consequences if you are
|
|
|
|
using Haxl with side-effecting data sources, so watch out!
|
|
|
|
|
|
|
|
* New function withEnv, for running a sub-computation in a local Env
|
|
|
|
|
|
|
|
* Add a higher-level memoization API, see 'memo'
|
|
|
|
|
|
|
|
* Show is no longer required for keys in cachedComputation
|
|
|
|
|
|
|
|
* Exceptions now have `Eq` instances
