* rewrite: add 'ir_' mod to support header only url-rewriting with no content rewriting
* tests: add tests for ir_ to test that content is identical to id_, but Location headers are rewritten with ir_ modifier.
* js rewriting: default to moden js-proxy based rewriting by default, use legacy rewriting only if browsers are older than minimum, as suggested in #707
* user-agent detection: use ua_parser for user-agent detection instead of obsolete werkzeug.useragent, which also did not support browsers >=100
* tests: additional tests for rewriting with various user-agents, defaulting to new-style rewriting for unknown browsers
* dockerfile: Update Dockerfile to use py3.8
* tests: skip s3 tests dependent on commoncrawl data (for now, need better s3 tests).
* bump to 2.6.6, update CHANGES
- fix proxy mode when 'redirect_to_exact=True' is set config, don't redirect in proxy mode
- more general prefer support, moved to content_rewriter to support preference<->mod mappings
- add 'banner-only' preference mapped to bn_ modifier
- proxy mode: allow 'raw' and 'banner-only' preferences
- proxy mode: 'Prefer: rewritten' forced to 'banner-only', served with 'Preference-Applied: banner-only'
- tests: test proxy with prefer header, 'redirect_to_exact=True', add 'banner-only' to Prefer header tests in rewriting mode
- Fix: a few broken tests due to iana.org requiring a user agent in its requests
rewrite:
- introduced a new JSWorkerRewriter class in order to support rewriting via wombat workers in the context of all supported worker variants via
- ensured rewriter app correctly sets the static prefix
wombat:
- add wombat as submodule!
* html rewrite: when encountering 'text/html' content-type, add html-detection check before assuming content is html (similar to text/plain)
supersedes #426, fixes#424 -- binary files served under mp_/ as text/html should now be served as binary
- when guessing if html, add additional regex to check if text does not start with < -- perhaps html but starting with plain text. only check for text/html content-type and not js_/cs_ mod
- allow custom 'rules.yaml' to be specified via 'rules_file' config entry,
and used by FuzzyMatcher and DefaultRewriter
- default rules file specified by DEFAULT_RULES_FILE in pywb package
- 'archive_paths' is the key for archive paths instead of 'resource'
- 'use_js_obj_proxy' not auto-added to metadata, just set per-deployment
- enumerate standard headers, prefix only known headers, keep others (like Date)
- don't rewrite custom headers by default
typo fixes: fix typo in wombat.js, fix special case rewrite_dash() for fb
* adaptive rewrite improvements:
- Add 'application/vnd.apple.mpegurl' as HLS type in rules.yaml and default_rewriter.py
- Support setting max resolution and max bandwidth to choose, defaults to 480x854 and 200000 respectively
- LiveWebLoader provides a get_custom_metadata for specifying WARC-JSON-Metadata header, per mime type (TODO: support customization via rules)
- When filtering, first limiting by resolution (if set), then by bandwidth (if set), otherwise default to max bandwidth
- Max resoluton/max bandwidth stored in WARC record under WARC-JSON-Metadata as 'adaptive_max_resolution' and 'adaptive_max_bandwidth' to ensure replayability. If absent, choose absolute max in manifest to be backwards compatible
- Add sample HLS and DASH manifests for testing, with and without max resolution/bandwidth settings.
- add special 'guess-none' and 'guess-bin' types for guessing content-type
- 'application/octet-stream' treated as 'guess-bin', treated as js or css if js_ or cs_
- tests: add tests for application/octet-stream detection, keeping charset
- guess-none applied for js_, cs_, as well as mp_ and default mod to guess html also
- if content-type missing, resolve if text type by checking for html and modifier
- if text type has changed, set default JS and CSS text type
- if text type is html, ensure mime type is text/html (force xhtml mime type to text/html)
tests: add test_content_rewriter for direct header + content rewriting tests
* 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
