• Minor enhancements

• Added Mechanize#follow_redirect= as an alias to redirect_ok=.

• Bug fix

• Fixed casing of the Mac Firefox user-agent alias to match Linux Firefox. In mechanize 3 the old "Mac FireFox" user-agent alias will be removed. Pull request #231 by Gavin Miller.

• Mechanize now authenticates using the raw challenge, not a reconstructed one, to avoid dealing with quoting rules of RFC 2617. Fixes failures in #231 due to net-http-digest_auth 1.2.1

• Fixed redirection counting in following meta refresh. #240

2.5.1¶ ↑

2.5¶ ↑

• Minor enhancements

• Added Mechanize#ignore_bad_chunking for working around servers that don't terminate chunked transfer-encoding properly. Enabling this may cause data loss. Issue #116

2.4¶ ↑

• Security fix:

Mechanize#auth and Mechanize#basic_auth allowed disclosure of passwords to malicious servers and have been deprecated.

In prior versions of mechanize only one set of HTTP authentication credentials were allowed for all connections. If a mechanize instance connected to more than one server then a malicious server detecting mechanize could ask for HTTP Basic authentication. This would expose the username and password intended only for one server.

Mechanize#auth and Mechanize#basic_auth now warn when used.

To fix the warning switch to Mechanize#add_auth which requires the URI the credentials are intended for, the username and the password. Optionally an HTTP authentication realm or NTLM domain may be provided.

• Minor enhancement

• Improved exception messages for 401 Unauthorized responses. Mechanize now tells you if you were missing credentials, had an incorrect password, etc.

2.3 / 2012-02-20¶ ↑

• Minor enhancements

• Add support for the Max-Age attribute in the Set-Cookie header.

• Added Mechanize::Download#body for compatibility with Mechanize::File when using Mechanize#get_file with Mechanize::Image or other Download-based pluggable parser. Issue #202 by angas

• Mechanize#max_file_buffer may be set to nil to disable creation of Tempfiles.

• Bug fixes

• Applied Mechanize#max_file_buffer to the Content-Encoding handlers as well to prevent extra Tempfiles for small gzip or deflate response

• Increased the default Mechanize#max_file_buffer to 100,000 bytes. This gives ~5MB of response bodies in memory with the default history setting of 50 pages (depending on GC behavior).

• Ignore empty path/domain attributes.

• Cookies with an empty Expires attribute value were stored as session cookies but cookies without the Expires attribute were not. Issue #78

2.2.1 / 2012-02-13¶ ↑

• Bug fixes

• Add missing file to the gem, ensure that missing files won’t cause failures again. Issue #201 by Alex

• Fix minor grammar issue in README. Issue #200 by Shane Becker.

2.2 / 2012-02-12¶ ↑

• API changes

• MetaRefresh#href is not normalized to an absolute URL, but set to the original value and resolved later. It is even set to nil when the Refresh URL is unspecified or empty.

• Minor enhancements

• Expose ssl_version from net-http-persistent. Patch by astera.

• SSL parameters and proxy may now be set at any time. Issue #194 by dsisnero.

• Improved Mechanize::Page with image_with and images_with and Mechanize::Page::Image various img element attribute accessors, caption, extname, mime_type and fetch. Pull request #173 by kitamomonga

• Added MIME type parsing for content-types in Mechanize::PluggableParser for fine-grained parser choices. Parsers will be chosen based on exact match, simplified type or media type in that order. See Mechanize::PluggableParser#[]=.

• Added Mechanize#download which downloads a response body to an IO-like or filename.

• Added Mechanize::DirectorySaver which saves responses in a single directory. Issue #187 by yoshie902a.

• Added Mechanize::Page::Link#noreferrer?

• The documentation for Mechanize::Page#search and at now show that both XPath and CSS expressions are allowed. Issue #199 by Shane Becker.

• Bug fixes

• Fixed handling of a HEAD request with Accept-Encoding: gzip. Issue #198 by Oleg Dashevskii

• Use resolve for resolving a Location header value. fixes #197

• A Refresh value can have whitespaces around the semicolon and equal sign.

• MetaRefresh#click no longer sends out Referer.

• A link with an empty href is now resolved correctly where previously the query part was dropped.

2.1.1 / 2012-02-03¶ ↑

• Bug fixes

• Set missing idle_timeout default. Issue #196

• Meta refresh URIs are now escaped (excluding %). Issue #177

• Fix charset name extraction. Issue #180

• A Referer URI sent on request no longer includes user information or fragment part.

• Tempfiles for storing response bodies are unlinked upon creation to avoid possible lack of finalization. Issue #183

• The default maximum history size is now 50 pages to avoid filling up a disk with tempfiles accidentally. Related to Issue #183

• Errors in bodies with deflate and gzip responses now result in a Mechanize::Error instead of silently being ignored and causing future errors. Issue #185

• Mechanize now raises an UnauthorizedError instead of crashing when a 403 response does not contain a www-authenticate header. Issue #181

• Mechanize gives a useful exception when attempting to click buttons across pages. Issue #186

• Added note to Mechanize#cert_store describing how to add certificates in case your system does not come with a default set. Issue #179

• Invalid content-disposition headers are now ignored. Issue #191

• Fix NTLM by recognizing the “Negotiation” challenge instead of endlessly looping. Issue #192

• Allow specification of the NTLM domain through Mechanize#auth. Issue #193

• Documented how to convert a Mechanize::ResponseReadError into a File or Page, along with a new method force_parse. Issue #176

2.1 / 2011-12-20¶ ↑

• Deprecations

• Mechanize#get no longer accepts an options hash.

• Mechanize::Util::to_native_charset has been removed.

• Minor enhancements

• Mechanize now depends on net-http-persistent 2.3+. This new version brings idle timeouts to help with the dreaded “too many connection resets” issue when POSTing to a closed connection. Issue #123

• SSL connections will be verified against the system certificate store by default.

• Added Mechanize#retry_change_requests to allow mechanize to retry POST and other non-idempotent requests when you know it is safe to do so. Issue #123

• Mechanize can now stream files directly to disk without loading them into memory first through Mechanize::Download, a pluggable parser for downloading files.

  All responses larger than Mechanize#max_file_buffer are downloaded to a Tempfile. For backwards compatibility Mechanize::File subclasses still load the response body into memory.

  To force all unknown content types to download to disk instead of memory set:

  agent.pluggable_parser.default = Mechanize::Download

• Added Mechanize#content_encoding_hooks which allow handling of non-standard content encodings like "agzip". Patch #125 by kitamomonga

• Added dom_class to elements and the element matcher like dom_id. Patch #156 by Dan Hansen.

• Added support for the HTML5 keygen form element. See dev.w3.org/html5/spec/Overview.html#the-keygen-element Patch #157 by Victor Costan.

• Mechanize no longer follows meta refreshes that have no “url=” in the content attribute to avoid infinite loops. To follow a meta refresh to the same page set Mechanize#follow_meta_refresh_self to true. Issue #134 by Jo Hund.

• Updated ‘Mac Safari’ User-Agent alias to Safari 5.1.1. ‘Mac Safari 4’ can be used for the old ‘Mac Safari’ alias.

• When given multiple HTTP authentication options mechanize now picks the strongest method.

• Improvements to HTTP authorization:

  • mechanize raises Mechanize::UnauthorizedError for 401 responses which is a subclass of Mechanize::ResponseCodeError.

  • Added support for NTLM authentication, but this has not been tested.

• Mechanize::Cookie.new accepts attributes in a hash.

• Mechanize::CookieJar#<<(cookie) (alias: add!) is added. Issue #139

• Different mechanize instances may now have different loggers. Issue #122

• Mechanize now accepts a proxy port as a service name or number string. Issue #167

• Bug fixes

• Mechanize now handles cookies just as most modern browsers do, roughly based on RFC 6265.

  • domain=.example.com (which is invalid) is considered identical to domain=example.com.

  • A cookie with domain=example.com is sent to host.sub.example.com as well as host.example.com and example.com.

  • A cookie with domain=TLD (no dots) is accepted and sent if the host name is TLD, and rejected otherwise. To retain compatibility and convention, host/domain names starting with "local" are exempt from this rule.

  • A cookie with no domain attribute is only sent to the original host.

  • A cookie with an Effective TLD is rejected based on the public suffix list. (cf. publicsuffix.org/)

  • "Secure" cookies are not sent via non-https connection.

  • Subdomain match is not performed against an IP address.

  • It is recommended that you clear out existing cookie jars for regeneration because previously saved cookies may not have been parsed correctly.

• Mechanize takes more care to avoid saving files with certain unsafe names. You should still take care not to use mechanize to save files directly into your home directory ($HOME). Issue #163.

• Mechanize#cookie_jar= works again. Issue #126

• The original Referer value persists on redirection. Issue #150

• Do not send a referer on a Refresh header based redirection.

• Fixed encoding error in tests when LANG=C. Patch #142 by jinschoi.

• The order of items in a form submission now match the DOM order. Patch #129 by kitamomonga

• Fixed proxy example in EXAMPLE. Issue #146 by NielsKSchjoedt

2.0.1 / 2011-06-28¶ ↑

Mechanize now uses minitest to avoid 1.9 vs 1.8 assertion availability in test/unit

• Bug Fixes

• Restored Mechanize#set_proxy. Issue #117, #118, #119

• Mechanize::CookieJar#load now lazy-loads YAML. Issue #118

• Mechanize#keep_alive_time no longer crashes but does nothing as net-http-persistent does not support HTTP/1.0 keep-alive extensions.
