# 0.18.3 (07-03-2017)
|
|
|
|
- Remove `Gzip::Header` monkey patch since it's fixed in `Crystal 0.21.1`.
|
|
|
|
# 0.18.2 (24-02-2017)
|
|
|
|
- Fix [Gzip in Kemal Seems broken for static files](https://github.com/kemalcr/kemal/issues/316). This was caused by `Gzip::Writer` in `Crystal 0.21.0` and currently mitigated by monkey patching `Gzip::Header`.
|
|
|
|
# 0.18.1 (21-02-2017)
|
|
|
|
- Crystal 0.21.0 support
|
|
- Drop `multipart.cr` dependency. `multipart` support is now built-into Crystal <3
|
|
- Since Crystal 0.21.0 comes built-in with `multipart` there are some improvements and deprecations.
|
|
|
|
`meta` has been removed from `FileUpload` and it has the following properties
|
|
|
|
+ `tmpfile`: This is temporary file for file upload. Useful for saving the upload file.
|
|
+ `filename`: File name of the file upload. (logo.png, images.zip e.g)
|
|
+ `headers`: Headers for the file upload.
|
|
+ `creation_time`: Creation time of the file upload.
|
|
+ `modification_time`: Last Modification time of the file upload.
|
|
+ `read_time`: Read time of the file upload.
|
|
+ `size`: Size of the file upload.
|
|
|
|
|
|
# 0.18.0 (11-02-2017)
|
|
|
|
- Simpler file upload. File uploads can now be access from `HTTP::Server::Context` like `env.params.files["filename"]`.
|
|
|
|
`env.params.files["filename"]` has 5 methods
|
|
|
|
- `tmpfile`: This is temporary file for file upload. Useful for saving the upload file.
|
|
- `tmpfile_path`: File path of `tmpfile`.
|
|
- `filename`: File name of the file upload. (logo.png, images.zip e.g)
|
|
- `meta`: Meta information for the file upload.
|
|
- `headers`: Headers for the file upload.
|
|
|
|
Here's a fully working sample for reading a image file upload `image1` and saving it under `public/uploads`.
|
|
|
|
```crystal
|
|
post "/upload" do |env|
|
|
file = env.params.files["image1"].tmpfile
|
|
file_path = ::File.join [Kemal.config.public_folder, "uploads/", file.filename]
|
|
File.open(file_path, "w") do |f|
|
|
IO.copy(file, f)
|
|
end
|
|
"Upload ok"
|
|
end
|
|
```
|
|
|
|
To test
|
|
|
|
`curl -F "image1=@/Users/serdar/Downloads/kemal.png" http://localhost:3000/upload`
|
|

|
# 0.17.1 (24-11-2016)
|
|
|
|
- Treat `HTTP::Request` body as an `IO`. Fixes [#257](https://github.com/sdogruyol/kemal/issues/257)
|
|
|
|
# 0.17.0 (23-11-2016)
|
|
|
|
- Reimplemented Request middleware / filter routing.
|
|
|
|
Now all requests will first go through the Middleware stack then Filters (before_*) and will finally reach the matching route.
|
|
|
|
Which is illustrated as,
|
|
|
|
```
|
|
Request -> Middleware -> Filter -> Route
|
|
```
|
|
|
|
- Rename `return_with` as `halt`.
|
|
- Route declaration must start with `/`. Fixes [#242](https://github.com/sdogruyol/kemal/issues/242)
|
|
- Set default exception Content-Type to text/html. Fixes [#202](https://github.com/sdogruyol/kemal/issues/242)
|
|
- Add `only` and `exclude` paths for `Kemal::Handler`. This change requires that all handlers must inherit from `Kemal::Handler`.
|
|
|
|
For example this handler will only work on `/` path. By default the HTTP method is `GET`.
|
|
|
|
|
|
```crystal
|
|
class OnlyHandler < Kemal::Handler
|
|
only ["/"]
|
|
|
|
def call(env)
|
|
return call_next(env) unless only_match?(env)
|
|
puts "If the path is / i will be doing some processing here."
|
|
end
|
|
end
|
|
```
|
|
|
|
The handlers using `exclude` will work on the paths that isn't specified. For example this handler will work on any routes other than `/`.
|
|
|
|
```crystal
|
|
class ExcludeHandler < Kemal::Handler
|
|
exclude ["/"]
|
|
|
|
def call(env)
|
|
return call_next(env) unless only_match?(env)
|
|
puts "If the path is NOT / i will be doing some processing here."
|
|
end
|
|
end
|
|
```
|
|
|
|
- Close response on `halt`. (thanks @samueleaton).
|
|
- Update `Radix` to `v0.3.4`.
|
|
- `error` handler now also yields error. For example you can get the error mesasage like
|
|
|
|
```crystal
|
|
error 500 do |env, err|
|
|
err.message
|
|
end
|
|
```
|
|
|
|
- Update `multipart.cr` to `v0.1.1`
|
|
|
|
# 0.16.1 (12-10-2016)
|
|
|
|
- Improved Multipart support with more info on parsed files. `parse_multipart(env)` now yields
|
|
an `UploadFile` object which has the following properties `field`,`data`,`meta`,`headers.
|
|
|
|
```crystal
|
|
post "/upload" do |env|
|
|
parse_multipart(env) do |f|
|
|
image1 = f.data if f.field == "image1"
|
|
image2 = f.data if f.field == "image2"
|
|
puts f.meta
|
|
puts f.headers
|
|
"Upload complete"
|
|
end
|
|
end
|
|
```
|
|
|
|
# 0.16.0
|
|
|
|
- Multipart support <3 (thanks @RX14). Now you can handle file uploads.
|
|
|
|
```crystal
|
|
post "/upload" do |env|
|
|
parse_multipart(env) do |field, data|
|
|
image1 = data if field == "image1"
|
|
image2 = data if field == "image2"
|
|
"Upload complete"
|
|
end
|
|
end
|
|
```
|
|
|
|
- Make session configurable. Now you can specify session name and expire time wit
|
|
|
|
```crystal
|
|
Kemal.config.session["name"] = "your_app"
|
|
Kemal.config.session["expire_time"] = 48.hours
|
|
```
|
|
|
|
- Session now supports more types. (String, Int32, Float64, Bool)
|
|
- Add `gzip` helper to enable / disable gzip compression on responses.
|
|
- Static file caching with etag and gzip (thanks @crisward)
|
|
- `Kemal.run` now accepts port to listen.
|
|
|
|
# 0.15.1 (05-09-2016)
|
|
|
|
- Don't forget to call_next on NullLogHandler
|
|
|
|
# 0.15.0 (03-09-2016)
|
|
|
|
- Add context store
|
|
- `KEMAL_ENV` respects to `Kemal.config.env` and needs to be explicitly set.
|
|
- `Kemal::InitHandler` is introduced. Adds initial configuration, headers like `X-Powered-By`.
|
|
- Add `send_file` to helpers.
|
|
