8−* The versions of tools you're using (e.g. `stack`, `ghc`).
9−* The versions of dependencies you're using
10−
11−For your convenience, we recommend pasting this script into bash and uploading the output [as a gist](https://gist.github.com/).

20−
21−* Also, is there anything custom or unusual about your setup? i.e. new or prerelease versions of GHC, Stack, etc.
22−
23−* Finally, if possible, please reproduce the error in a small script, or if necessary create a new Github repo with the smallest possible reproducing case. [Stack's scripting support](https://docs.haskellstack.org/en/stable/GUIDE/#script-interpreter) might be useful for creating your reproduction example.

20−## Coding Guidelines
21−
22−### Safety
23−
24−Avoid partial functions. Even if you know the partial function is safe in your instance, partial functions require more reasoning from the programmer and are not resilient to refactoring. For the rare cases where a partial function is appropriate, a custom `error` should be used.
25−
26−### Style
27−
28−Keep coding style consistent with the rest of the file, but don't worry about style too much otherwise. PRs changing code style are viewed skeptically.
29−
30−### Dependencies
31−
32−Avoid adding unnecessary dependencies. If a dependency provides only a minor convenience for your implementation, it's probably better to skip it.
33−
34−If you do add a new dependency, try to support a wide range of versions of it.
35−
36−### Backwards Compatibility
37−
38−Backwards incompatible changes are viewed skeptically—best to ask in an issue to see if a particular backwards incompatible change would be approved. If possible keep backwards compatibility by adding new APIs and deprecating old ones.
39−
40−Keep backwards compatibility with old versions of dependencies when possible.
41−
42−## PR Guidelines
43−
44−### PR Scope
45−
46−As much as possible, keep separate changes in separate PRs.
47−
48−### Testing
49−
50−Tests are recommended, but not required.
51−
52−### Documentation
53−
54−All public APIs must be documented. Documenting private functions is optional, but may be nice depending on their complexity. Example documentation:
55−
56−```
57−-- | Generate an action which will either read from an automatically
58−-- updated value, or run the update action in the current thread.
59−--
60−-- ==== __Examples__
61−--
62−-- > getTime <- mkAutoUpdate defaultUpdateSettings
63−--
64−-- @since 0.1.0
65−mkAutoUpdate :: UpdateSettings a -> IO (IO a)
66−```
67−
68−Examples are recommended, but not required, in documentation. Marking new APIs with `@since <version number>` is required.
69−
70−### Versioning
71−
72−Wai packages roughly follow the Haskell Package Versioning Policy style of A.B.C.[D] (MAJOR.MAJOR.MINOR.[PATCH])
73−
74−* A - Used for massive changes in the library. (Example: 1.2.3.4 becomes 2.0.0)
75−* B - Used for smaller breaking changes, like removing, renaming, or changing behavior of existing public API. (Example: 1.2.3.4 becomes 1.3.0)
76−* C - Used for new public APIs (Example: 1.2.3.4 becomes 1.2.4)
77−* D - Used for bug fixes (Example: 1.2.3.4 becomes 1.2.3.5).
78− * D is optional in the version number, so 2.0.0 is a valid version.
79−
80−Documentation changes don't require a new version.
81−
82−If you feel there is ambiguity to a change (e.g. fixing a bug in a function, when people may be relying on the old broken behavior), you can ask in an issue or pull request.
83−
84−Unlike in the Package Versioning Policy, deprecations are not counted as MAJOR changes.
85−
86−In some cases, dropping compatibility with a major version of a dependency (e.g. changing from transformers >= 0.3 to transformers >= 0.4), is considered a breaking change.
87−
88−### Changelog
89−
90−After you submit a PR, update the subproject's Changelog.md file with the new version number and a link to your PR. If your PR does not need to bump the version number, include the change in an "Unreleased" section at the top.
91−
92−### Releases
93−
94−Releases should be done as soon as possible after a pull request is merged—don't be shy about reminding us to make a release if we forget.

2−-- | In a multithreaded environment, running actions on a regularly scheduled
3−-- background thread can dramatically improve performance.
4−-- For example, web servers need to return the current time with each HTTP response.
5−-- For a high-volume server, it's much faster for a dedicated thread to run every
6−-- second, and write the current time to a shared 'IORef', than it is for each
7−-- request to make its own call to 'getCurrentTime'.
8−--
9−-- But for a low-volume server, whose request frequency is less than once per
10−-- second, that approach will result in /more/ calls to 'getCurrentTime' than
11−-- necessary, and worse, kills idle GC.
12−--
13−-- This library solves that problem by allowing you to define actions which will
14−-- either be performed by a dedicated thread, or, in times of low volume, will
15−-- be executed by the calling thread.
16−--
17−-- Example usage:
18−--
19−-- @
20−-- import "Data.Time"
21−-- import "Control.AutoUpdate"
22−--
23−-- getTime <- 'mkAutoUpdate' 'defaultUpdateSettings'

25−-- , 'updateFreq' = 1000000 -- The default frequency, once per second
26−-- }

3−A common problem is the desire to have an action run at a scheduled interval,
4−but only if it is needed. For example, instead of having every web request
5−result in a new `getCurrentTime` call, we'd like to have a single worker thread
6−run every second, updating an `IORef`. However, if the request frequency is
7−less than once per second, this is a pessimization, and worse, kills idle GC.
8−
9−This library allows you to define actions which will either be performed by a
10−dedicated thread or, in times of low volume, will be executed by the calling
11−thread.

55−-- $howto
56−-- This module provides 'Middleware' to rewrite URL paths. It also provides
57−-- functions that will convert a 'Request' to a modified 'Request'.
58−-- Both operations require a function that takes URL parameters and
59−-- headers, and returns new URL parameters. Parameters are pieces of URL
60−-- paths and query parameters.
61−--
62−-- If you are a new user of the library, use 'rewriteWithQueries' or
63−-- 'rewritePureWithQueries' for middleware. For modifying 'Request's
64−-- directly, use 'rewriteRequest' or 'rewriteRequestPure'.
65−
66−-- $semantics
67−--
68−-- Versions of this library in wai-extra ≤ 3.0.16.1 exported only
69−-- 'rewrite' and 'rewritePure' and both modified 'rawPathInfo' of the
70−-- underlying requests. Such modification has been proscribed. The
71−-- semantics of these functions have not changed; instead the recommended
72−-- approach is to use 'rewriteWithQueries' and 'rewritePureWithQueries'.
73−-- The new functions are slightly different, as described in the section
74−-- on upgrading; code for previous library versions can be upgraded with
75−-- a single change, and as the type of the new function is different the
76−-- compiler will indicate where this change must be made.
77−--
78−-- The 'rewriteRequest' and 'rewriteRequestPure' functions use the new
79−-- semantics, too.

81−-- $pathsandqueries
82−--
83−-- This library defines the type synonym `PathsAndQueries` to make code
84−-- handling paths and queries easier to read.

3+Synopsis: WAI server that automatically reloads code after modification.
4+Description: This handler automatically reloads your source code upon any changes. It works by using the hint package, essentially embedding GHC inside the handler. The handler (both the executable and library) takes three arguments: the port to listen on, the module name containing the application function, and the name of the function.
5+ .
6+ One major note: the type of the application is most likely not what you expect. A common case for WAI applications is having a withApplication function, and this library assumes this is the case. Therefore, the type signature of your application function must be:

2+==================
3+
4+Turn WAI applications into standalone GUIs using Qt WebKit.
5+
6+
7+Linux
8+-----
9+
10+You'll need the appropriate system libraries, on Ubuntu:
11+
12+ apt-get install libqtwebkit-dev
13+
14+On Lucid, this required adding a PPA:
15+
16+ sudo add-apt-repository ppa:kubuntu-ppa/backports
17+
18+
19+Windows
20+-------
21+
22+Install the Qt SDK from <http://qt.nokia.com/downloads/>
23+
24+Your application's Cabal file will require certain options for Windows,
25+shown below. In particular, we need to link with `g++`, so make sure
26+it's in your `PATH`. The option `-optl-mwindows` ensures that the
27+application does not open a terminal.
28+
29+ if os(windows)
30+ ghc-options: -Wall -threaded -pgml g++ -optl-static -optl-mwindows
31+ else
32+ ghc-options: -Wall
33+
34+Run `cabal-install` with the Qt `include` and `lib` directories.
35+
36+ export QT_PATH=c:/QtSDK/Desktop/Qt/4.7.3/mingw
37+
38+ cabal-dev install \
39+ --extra-include-dirs=$QT_PATH/include \
40+ --extra-include-dirs=$QT_PATH/include/QtCore \
41+ --extra-include-dirs=$QT_PATH/include/QtNetwork \
42+ --extra-include-dirs=$QT_PATH/include/QtGui \
43+ --extra-include-dirs=$QT_PATH/include/QtWebKit \
44+ --extra-lib-dirs=$QT_PATH/lib
45+
46+You'll need to include these DLLs with your application:
47+
48+ phonon4.dll
49+ libgcc_s_dw2-1.dll
50+ QtCore4.dll
51+ QtGui4.dll
52+ QtNetwork4.dll

363−Modify flushing of request bodies. Previously, regardless of the size of the
364−request body, the entire body would be flushed. When uploading large files to a
365−web app that does not accept such files (e.g., returns a 413 too large status),
366−browsers would still send the entire request body and the servers will still
367−receive it.
368−
369−The new behavior is to detect if there is a large amount of data still to be
370−consumed and, if so, immediately terminate the connection. In the case of
371−chunked request bodies, up to a maximum number of bytes is consumed before the
372−connection is terminated.

385−`responseRaw` response has been added, which provides a more elegant way to
386−handle WebSockets than the previous `settingsIntercept`. The old settings
387−accessors have been deprecated in favor of new setters, which will allow

2023-- | A fast, light-weight HTTP server handler for WAI.
21−--
22−-- HTTP\/1.0, HTTP\/1.1 and HTTP\/2 are supported. For HTTP\/2,
23−-- Warp supports direct and ALPN (in TLS) but not upgrade.
24−--
25−-- Note on slowloris timeouts: to prevent slowloris attacks, timeouts are used

29−-- again. Therefore, it is recommended that once you start consuming the

31−--
32−-- * consume the entire body promptly
33−--

51−--
52−-- Applications/middlewares MUST provide a proper 'H.ResponseHeaders'.
53−-- so that inconsistency does not happen.
54−-- No header is deleted by this function.
55−--
56−-- Especially, Applications/middlewares MUST provide a proper
57−-- Content-Type. They MUST NOT provide
58−-- Content-Length, Content-Range, and Transfer-Encoding
59−-- because they are inserted, when necessary,
60−-- regardless they already exist.
61−-- This function does not insert Content-Encoding. It's middleware's
62−-- responsibility.
63−--
64−-- The Date and Server header is added if not exist
65−-- in HTTP response header.
66−--
67−-- There are three basic APIs to create 'Response':
68−--
69−-- ['responseBuilder' :: 'H.Status' -> 'H.ResponseHeaders' -> 'Builder' -> 'Response']
70−-- HTTP response body is created from 'Builder'.
71−-- Transfer-Encoding: chunked is used in HTTP/1.1.

74−-- HTTP response body is created from 'Builder'.
75−-- Transfer-Encoding: chunked is used in HTTP/1.1.
76−--
77−-- ['responseRaw' :: ('IO' 'ByteString' -> ('ByteString' -> 'IO' ()) -> 'IO' ()) -> 'Response' -> 'Response']
78−-- No header is added and no Transfer-Encoding: is applied.
79−--
80−-- ['responseFile' :: 'H.Status' -> 'H.ResponseHeaders' -> 'FilePath' -> 'Maybe' 'FilePart' -> 'Response']
81−-- HTTP response body is sent (by sendfile(), if possible) for GET method.
82−-- HTTP response body is not sent by HEAD method.
83−-- Content-Length and Content-Range are automatically
84−-- added into the HTTP response header if necessary.
85−-- If Content-Length and Content-Range exist in the HTTP response header,
86−-- they would cause inconsistency.
87−-- \"Accept-Ranges: bytes\" is also inserted.
88−--
89−-- Applications are categorized into simple and sophisticated.
90−-- Sophisticated applications should specify 'Just' to
91−-- 'Maybe' 'FilePart'. They should treat the conditional request
92−-- by themselves. A proper 'Status' (200 or 206) must be provided.
93−--
94−-- Simple applications should specify 'Nothing' to
95−-- 'Maybe' 'FilePart'. The size of the specified file is obtained
96−-- by disk access or from the file infor cache.
97−-- If-Modified-Since, If-Unmodified-Since, If-Range and Range
98−-- are processed. Since a proper status is chosen, 'Status' is
