Other changes

If local dependency can't be found relative to the given ASDF system, we try to search the same path relative to the current directory and throw error if file can't be found. This could happen if you've compiled the webserver into a binary and moved it to another container or machine.

reblocks/server:start function now accepts SAMESITE-POLICY argument which should be one of keywords: :LAX, :STRICT or :NONE. This parameter modifies SameSite part of the cookies sent to the client.

Hooks API was refactored in a backward incompatible manner. reblocks/hooks:defhook macro now requires to specify hook's arguments and all macros generated by the reblocks/hooks:defhook also require arguments specification.

jQuery was upgraded from 1.8.2 to 3.6.0. It's plugins jquery.ba-bbq.js and jquery-seq.js were turned off.

0.39.1 (2020-01-20)

Fixed

https://github.com/fukamachi/woo/issues/84

Now Woo does not parses numeric headers and Weblocks has to do it itself.

0.39.0 (2019-09-16)

Changes

It defines a handler for a given route. By default route should return a serialized JSON:

(defroute (app /api/data)
    "{\"my-data\": [1, 2, 3]}")

but you can redefine the content type:

(defroute (app /api/data :content-type "application/xml")
    "<my-data><item>1</item><item>2</item></my-data>")

each route is associate with application class and these routes are added to the mapper when you call a start method.

0.38.1 (2019-08-02)

0.38.0 (2019-07-07)

All of them are fixed now.

0.37.0 (2019-06-01)

0.36.0 (2019-05-03)

0.35.3 (2019-03-31)

For example, calling:

(add-retpath-to "/login" :retpath
  "http://example.com:10050/foo/bar")

  Will return:

```lisp
"/login?retpath=http%3A%2F%2Fexample.com%3A10050%2Ffoo%2Fbar"

Argument :retpath is optional. By default, function will take an URL of the current web page.

0.35.2 (2019-03-21)

0.35.1 (2019-02-02)

This was fixed now.

0.35.0 (2019-01-22)

Request handling pipeline was refactored.

The idea of this refactoring, is to separate roles of the functions which process requests. Now weblocks/server:handle-http-request prepares data received from the Clack and calls weblocks/request-handler:handle-request to do the real job.

In it's turn, weblocks/request-handler:handle-request should return an object of type weblocks/response:response containing a content, HTTP status code and headers of the response. Any error signal, thrown from the handle-request is considered by handle-http-request as an "unhandled error" and returned with 500 HTTP status code.

Here is a list of changes:

0.34.0 (2019-01-19)

New

Changes

Fixes

0.33.2 (2018-12-06)

Fixes

0.33.1 (2018-11-24)

Improvements

(log4cl-json:setup)

Fixes

For example:

(weblocks/hooks:on-application-hook-handle-request
  connect-to-database ()

  (let ((success nil))
    (unwind-protect (progn (setup-transaction)
                           (weblocks/hooks:call-next-hook)
                           (setf success t))
      (if success
          (commit)
          (rollback)))))

Before this fix, rollback always called, because execution never hitted (setf success t). Now this is fixed.

0.33.0 (2018-11-22)

Changes

Use weblocks/response:make-uri instead.

Fixes

0.32.1 (2018-08-13)

Changes

Fixes

The error was raised during code loading:

;;; > Error: There is no applicable method for the generic function: > #<STANDARD-GENERIC-FUNCTION WEBLOCKS/JS/BASE:MAKE-JS-BACKEND #x3020027E292F> > when called with arguments: > (:JQUERY)

Now it is fixed and package weblocks/js/jquery is a dependency of weblocks/server and always loads.

0.32.0 (2018-06-26)

0.31.1 (2018-06-16)

0.31.0 (2018-05-29)

https://github.com/ruricolist/spinneret/commit/06b280612aff07cf376f593746d080230f2c7462

0.30.1 (2018-05-20)

However, it does not work with Woo server, because C library libev crashes with error:

Assertion failed: (("libev: a signal must not be attached to two different loops", !signals [w->signum - 1].loop || signals [w->signum - 1].loop == loop)), function ev_signal_start, file ev.c, line 4082

0.30.0 (2018-05-19)

0.29.0 (2018-05-05)

Backward incompatibilities

Class weblocks/dependencies:dependency now requires that type attribute shoulde be of type (member :css :js :png :jpg :gif)

Also, functions make-local-js-dependency, make-local-css-dependency, make-local-image-dependency, make-remote-js-dependency and make-remote-css-dependency were removed from package weblocks/dependencies. Use make-dependency function, it will figure out which dependency type to create itself.

Improvements

A new function weblocks/debug:get-session-value was added. It can be used to get values from the last session seen by weblocks.

0.28.0 (2018-04-23)

Error handling was fixed. Previously it aborted Woo's worker thread and break the server.

Variable weblocks/variables::*catch-errors-p* was renamed to weblocks/variables::*invoke-debugger-on-error* and it's value was inverted. If this variable is True, then debugger will be invoked. Otherwise - Weblocks will return 500 error page.

Argument :invoke-debugger-on-errors of weblocks/debug:on function was renamed to :invoke-debugger-on-error.

Method weblocks/error-handler:on-error now is called when you abort request processing from the debugger. It is called with current app as the first argument and the nil instead of condition.

0.27.2 (2018-04-09)

Fixed a typo in string-widget and funcall-widget package definitions.

0.27.1 (2018-04-09)

Now string-widget and funcall-widget depends on weblocks/widgets/base instead of weblocks/widget.

0.27.0 (2018-03-11)

Reloading of the defapp definition now does not tries to restart an application. Previously, restart caused the problem – when there is only one application, whole Weblocks server was shut down. So, I've removed this implicit action.

Code which logs action result on the client-side was improved.

0.26.0 (2018-02-20)

Symbols add-application-hook, add-request-hook, add-session-hook, prepare-hooks and call-hook aren't exported from weblocks/hooks anymore. Use new macro defhook instead.

Here is how it works:

You use defhook as the toplevel form of your file if you want to define a new hook. This macro will create few other macroses in weblocks/hooks package and will export them. For example:

(defhook database-opened
   "This hook is called when your application opens a database.")

This code will add these macroses into the weblocks/hooks package: on-session-hook-database-opened, on-request-hook-database-opened, on-application-hook-database-opened, with-database-opened-hook and call-database-opened-hook.

You need to wrap code, which opens a database, with with-database-opened-hook:

(weblocks/hooks:with-database-opened-hook ()
   (do-some-staff-to-open-database))

And in any other piece of code, you can define callbacks, using one of other three macroses:

(weblocks/hooks:on-session-hook-database-opened
    log-database-opening ()

  (weblocks/hooks:call-next-hook)
  (log:info "Database was opened"))

Usage of defhook macro gives more transparency to all defined hooks, because all of them now visible as external symbols in weblocks/hooks package.

0.25.2 (2018-02-04)

System weblocks/hooks now depends on log4cl and metatilities, because previously sometimes it was impossible to load weblocks.

0.25.1 (2018-02-04)

Old tests for widgets, removed from core framework were removed.

Tests for widget's MOP methods were ported to Rove.

Package weblocks/utils/close now loaded with main :weblocks system.

Few old widget tests were removed.

Added function weblocks/session:reset which resets current session.

0.25.0 (2018-01-31)

Good news, everyone!

Quickstart tutorial was fixed!

Function render-widget was replaced with weblocks/widget:render :around method. Method implementation were moved to weblocks/widgets/render-methods.

Funcall-widget's package was refactored to conform package inferred requirements.

Actions processing

Function make-js-action was moved to weblocks/actions package.

Application and server restarting

Package weblocks/app now exports functions stop and restart. Previously they were internal and were called like stop-webapp and restart-webapp.

Package weblocks/server does not export start-weblocks and stop-weblocks functions. They were replaced with just start and stop. Also, it's internal generics start and stop were renamed and transformed to start-server and stop-server functions.

Session initialization changes

File default-application.lisp was removed, because now every application has default session initialization method.

File default-init.lisp was refactored. Now it provides default method for weblocks/session:init generic and :around method for same generic, which allows end user just to return a string or a function from his init method.

Now user can return any string or function from his method weblocks/session:init and it will be passed to a new generic weblocks/widget:create-widget-from to create a root widget. You can also define create-widget-from for you custom types.

Debug

Function weblocks/debug:on now turns on mode when Weblocks does not intercept unhandled conditions, but calls an interactive debugger.

Removals

0.24.0 (2018-01-29)

All rendering code was refactored.

Macroses with-html and with-html-to-string replaced with weblocks.html:with-html and weblocks.html:with-html-string. Stream *weblocks-output-stream* was moved to weblocks.html::*stream* and is not external anymore. Please, don't use it directly.

Widget refactorings

Procedure update-widget-tree was removed and not widgets can't change html header's tags, description, title, etc. If you need this, change them in the render method.

Macro root-widget was removed and replaced with function weblocks.widgets.root:get.

Request level

Functions post-action-redirect, post-render-redirect and initial-request-p were removed from weblocks package.

Function pure-request-p was moved to weblocks.request package.

Variable *json-content-type* was removed.

Variable *latest-request* was moved to weblocks.debug:*latest-request*.

Functions parse-location-hash, ajax-request-p were moved to weblocks.request package.

Function redirect was moved to weblocks.response:redirect. Functionality, related to opening another window instead of redirection or deferring redirection until the end of action or rendering was removed.

Request handler

Functions remove-duplicate-dirty-widgets, update-location-hash-dependents and update-widget-tree were removed.

Call to weblocks::update-dialog-on-request from handle-client-request was commented.

Generic method weblocks/error-handler:on-error now accepts two arguments - application object and condition.

Application level

All code from uri-parameters-slotmap.lisp was removed.

All code, related to application class, was moved to the package weblocks.app. Base aplication class was renamed to weblocks.app:app, and macro for definition of the new application was renamed to weblocks.app:defapp.

All code related to application's metaclass, was moved to the package weblocks.app-mop. Metaclass was renamed to weblocks.app-mop:app-class.

Application's slot html-indent-p and corresponding accessor weblocks-webapp-html-indent-p were removed because now spinneret generates non indented code.

Slot init-user-session was completely removed and replace with a generic weblocks.session:init.

These dependency related slots and accessors were removed:

And macro for defining a special readers for them was removed as well: def-debug-p-slot-readers.

Also, these arguments to defapp was removed: :ignore-default-dependencies, :dependencies

Function update-thread-status and method webapp-update-thread-status were removed.

Function get-webapps-for-class was renamed to app-active-p and now returns t if application of given class is already active.

Function find-app was removed.

Function in-webapp was moved to weblocks.debug:in-app.

Variable *default-webapp* was removed.

Variable *active-webapps* was renamed to weblocks.app::*active-apps* and made internal. Use weblocks.app:get-active-apps function.

Most functions from weblocks.request were refactored and renamed:

All these function now accept keyword argument :request. Previously it was &optional.

Another change is a new function weblocks.response:make-uri. It can be used to build new uri, based on the uri of the current request. This can be useful when embedding links into emails, for example.
