* Init commit for Wombat JS Proxies off of https://github.com/ikreymer/pywb/tree/develop
Changes
- cli.py: add import os for os.chdir(self.r.directory)
- frontendapp.py: added initial support for cors requests.
- static_handler.py: add import for NotFoundException
- wbrequestresponse.py: added the intital implementation for cors requests, webrecoder needs this for recording!
- default_rewriter.py: added JSWombatProxyRewriter to default js rewriter class for internal testing
- html_rewriter.py: made JSWombatProxyRewriter to be default js rewriter class for internal testing
- regex_rewriters.py: implemented JSWombatProxyRewriter and JSWombatProxyRewriter to support wombat JS Proxy
- wombat.js: added JS Proxy support
- remove print
* wombat proxy: simplify mixin using 'first_buff'
* js local scope rewrite/proxy work:
- add DefaultHandlerWithJSProxy to enable new proxy rewrite (disabled by default)
- new proxy toggleable with 'js_local_scope_rewrite: true'
- work on integrating john's proxy work
- getAllOwnProps() to generate list of functions that need to be rebound
- remove non-proxy related changes for now, remove angular special cases (for now)
* local scope proxy work:
- add back __WB_pmw() prefix for postMessage
- don't override postMessage() in proxy obj
- MessageEvent resolve proxy to original window obj
* js obj proxy: use local_init() to load local vars from proxy obj
* wombat: js object proxy improvements:
- use same object '_WB_wombat_obj_proxy' on window and document objects
- reuse default_proxy_get() for get operation from window or document
- resolve and Window/Document object to the proxy, eg. if '_WB_wombat_obj_proxy' exists, return that
- override MessageEvent.source to return window proxy object
* obj proxy work:
- window proxy: defineProperty() override calls Reflect.defineProperty on dummy object as well as window to avoid exception
- window proxy: set() also sets on dummy object, and returns false if Reflect.set returns false (eg. altered by Reflect.defineProperty disabled writing)
- add override_prop_to_proxy() to add override to return proxy obj for attribute
- add override for Node.ownerDocument and HTMLElement.parentNode to return document proxy
server side rewrite: generalize local proxy insert, add list for local let overrides
* js obj proxy work:
- add default '__WB_pmw' to self if undefined (for service workers)
- document.origin override
- proxy obj: improved defineProperty override to work with safari
- proxy obj: catch any exception in dummy obj setter
* client-side rewriting:
- proxy obj: catch exception (such as cross-domain access) in own props init
- proxy obj: check for self reference '_WB_wombat_obj_proxy' access to avoid infinite recurse
- rewrite style: add 'cursor' attr for css url rewriting
* content rewriter: if is_ajax(), skip JS proxy obj rewriting also (html rewrite also skipped)
* client-side rewrite: rewrite 'data:text/css' as inline stylesheet when set via setAttribute() on 'href' in link
* client-side document override improvements:
- fix document.domain, document.referrer, forms add document.origin overrides to use only the document object
- init_doc_overrides() called as part of proxy init
- move non-document overrides to main init
rewrite: add rewrite for "Function('return this')" pattern to use proxy obj
* js obj proxy: now a per-collection (and even a per-request) setting 'use_js_obj_prox' (defaults to False)
live-rewrite-server: defaults to enabled js obj proxy
metadata: get_metadata() loads metadata.yaml for config settings for dynamic collections),
or collection config for static collections
warcserver: get_coll_config() returns config for static collection
tests: use custom test dir instead of default 'collections' dir
tests: add basic test for js obj proxy
update to warcio>=1.4.0
* karma tests: update to safari >10
* client-side rewrite:
- ensure wombat.js is ES5 compatible (don't use let)
- check if Proxy obj exists before attempting to init
* js proxy obj: RewriteWithProxyObj uses user-agent to determine if Proxy obj can be supported
content_rewriter: add overridable get_rewriter()
content_rewriter: fix elif -> if in should_rw_content()
tests: update js proxy obj test with different user agents (supported and unsupported)
karma: reset test to safari 9
* compatibility: remove shorthand notation from wombat.js
* js obj proxy: override MutationObserver.observe() to retrieve original object from proxy
wombat.js: cleanup, remove commented out code, label new proxy system functions, bump version to 2.40
setup.py just loads from requirements.txt
Dockerfile pip installs requirements, then extra requirements for improved cacheing
travis runs setup install, then installs extra requirements
