OpenACS TODO List

Release Status

See openacs-release-status

Development is taking place in the oacs-5-10 branch.

OpenACS Version 5.10.1 Agenda/wish list

Version numbers:

Postponed for later releases:
- Implement subsite-singleton (in addition to the classical singleton)
- Say farewell to CVS
- Make more parts of xotcl-core a first-class citizen of the OpenACS core (e.g. database interface)
- Data bloat hygiene:
  - Rethink package parameter and portlet parameter data models
  - Parameters: include subsite-parameters in parameter resolution (package->subsite->global)
require NaviServer (i.e. drop AOLserver support).
Rationale: AOLserver cannot be compiled with the required modules with recent Tcl versions. Trying to backport NaviServer compatibility functions seems to be an overkill for the OpenACS project.

OpenACS Version 5.10.0 Agenda

Functional improvements
- Features:
  - Added additional page_contract filter: oneof(red|green|blue)
  - template::add_event_listener and template::add_confirm_handler now can target elements by CSS selector
  - Added text/markdown to the accepted text formats or rich-text widget
  - Support for range types in .xql files:
    PostgreSQL supports range types since 9.5. When using range types, square braces have to be used in SQL statements. Since OpenACS uses always Tcl substitution in .xql files, and OpenACS does NOT allow backslash substitution in these files, square brackets could not be escaped and therefore not be used in .xql files so far. This change allows now a developer to deactivate the substitution by passing e.g. -subst none to the db_* command using the .xql file. Valid values for -subst are all, none, vars, and commands, default is all which is exactly the behavior of previous releases. Therefore, this change is fully backward compatible.
  - Improved API browser: Visualization for code dependencies (which procs calls what, from where is a proc being called) and test-coverage
  - Warn site administrators about expiring certificates
  - Additional input types (and widgets) for ad_form:
    - checkbox_text
    - color
    - email
    - tel
    - url
    - number
    - file (multiple)
    - h5date and h5time: date and time fields using native HTML5 visualization and input normalization
  - Registry for .js and .css libraries: allow besides classical URLs symbolic names for loading external resources (e.g. jquery), this makes it easier to upgrade libraries in multiple packages (without running into problems with duplicate versions) and supports switching between CDN and local pathsURN. The existing implementation is based on URNs and extends the existing template-head API to support registration for URNs. A URN provides an abstraction and a single place for e.g. updating references to external resources when switching between a CDN and a locally stored resource, or when a resource should be updated. Instead of adding e.g. a CDN URL via template::head::add_script, one can add an URN and control its content from a single place. Use common namespaces for OpenACS such as urn:ad:css:* and urn:ad:js:*.
    - Register URNs:
      Example provider (e.g. in some theme):
```
   template::register_urn \ 
       -urn urn:ad:js:jquery \ 
       -resource /resources/xowiki/jquery/jquery.min.js
```
    - The registered URN can be used like classical URL after registration.
      
      Example consumer:
```
   template::head::add_javascript -src urn:ad:js:jquery
```
    - Declare composite files: Provide an interface to define that a .js file or a .css file contains multiple other .js/.css files in order to reduce the number of requests.
```
   template::head::includes -container urn:js::style.js -parts {urn:ad:js:jquery ...}
```
  - Improved support for streaming HTML: The new API function template::collect_body_scripts can be used to get the content of template::script or CSP calls (template::add_body_script, template::add_event_listener, template::add_body_handler, template::add_script) when streaming HTML (incremental HTML) is used. Before, these call could bot be used for streaming HTML.
- Reforms:
  - Dynamic blueprint reloading:
    - When reloading apm packages, watched files, etc. the NaviServer blueprint is now updated correctly. This solves the long-standing problem that changes for scheduled procedures required a restart of the server. Furthermore, the old-style reloading was based on a ever-growing list of reload operations each time a new reload was requested, causing slow-downs in long running server instances, especially, when new threads are started.
    - Now changes are applied to all NaviServer threads, including threads for schedules procedures, ns_jobs and the like. Note that the current job has to be finished before the changes can be applied.
    - For the transition, it is possible to switch between the classical reloading style and blueprint reloading by changing a variable in acs-tcl/tcl/apm-procs.tcl
  - Login:
    - Get rid of bugging "login page expired" messages. The 17 years old construct was replaced by newer means to avoid caching of form values from the login form. Admins of existing sites should set the kernel parameter LoginPageExpirationTime to 0
  - Forums:
    - Removed hard-coded dependency with registered_users group when checking forum permissions
    - Don't rely so heavily on acs_permissions to model forum configuration, as this can have unexpected consequences in convoluted multi-group/multi-subsite scenarios. Prefer simpler table attributes instead
    - New style of attachments to the forums, allowing multiple attachments to a single message directly from the message post page, using the multiple file input widget. Retain compatibility with old style attachments, using the new 'AttachmentStyle' package instance parameter. Currently, this supports two values: 'simple' (new behavior) and 'complex' previous behavior.
  - Chat:
    - Revamping of the GUI
    - Responsiveness
    - Full screen mode
    - Skins support (minimal, classic and bubbles, included): Skins are located in the new /packages/xowiki/www/resources/chat-skins/ directory. New skins can be created by just adding the css and js files in the skins directory, and naming them accordingly (chat-$SKIN_NAME.{js|css}).
    - Avatars (can be enabled per room)
    - Number of active users in chat
    - Tab notifications of new messages
    - Web Notifications:
      - https://www.w3.org/TR/notifications/
      - https://developer.mozilla.org/en-US/docs/Web/API/Notifications_API/Using_the_Notifications_API
  - acs-lang:
    - admin pages:
      - Added the option to unregister (delete permanently the message key from all locales) a message key that has been already marked as deleted. Useful for cleaning up old message keys.
      - Added the option to undelete, using the new ::message::undelete proc.
      - Made number and category (untranslated/deleted/...) of messages coherent in all pages.
      - Added the columns 'total' and 'deleted' to the index page.
    - object_id reference: it is now possible to associate a message key to an object_id in a way that e.g. when the object is deleted, so is the message key. This addresses cases such as the message keys generated by group creation or by the new XoWiki localized fields
  - Notifications:
    - Improved scalability for notifications: One of the most expensive operations in large site is the cleanup for notification_requests in situations, where the user has lost permissions on an object, on which the user wanted to receive notifications. This check was performed previously in notification::sweep::cleanup_notifications via a permission check over all notification requests, which can be very costly on large sites. This change moves this cleanup into the actual notification sending, where the permissions have to be sent anyhow.
    - When sending a notification on behalf of a person, if the system is not configured to process replies to notification, do not set the reply-to address to anything different than the sender
    - Notifications: proper cleanup of acs_objects resulting from the deletion of dynamic notification requests
  - User/Person/Party API: rework and rationalize caching of all party, person and user API, create separate caches for each of these types, make the API and return dicts. acs_user::get will not fail anymore with non-existing user.
  - User Portrait: created API to retrieve and create, store and delete the user's portrait. Also address leftover child relationships from the past and delete them properly.
Non-functional Changes
- Improved automated regression test infrastructure and test coverage
  - All packages in the oacs-5-10 branch pass regression test
  - Web testing was separated from non-maintained tcltest and was built on the standard OpenACS infrastructure
  - Include web testing per default in standard regression testing
  - Introduced new test authentication authority, allowing to run many user administration tests outside the context of a "real authority": in cases where the real authority depends on external services to proof identity, (e.g. Kerberos), those tests would just fail.
  - Introduce the display of warnings in the UI
  - Added test coverage information in the automated testing pages, using the new proc-coverage API and providing test coverage information for packages and system wide.
  - Increased overall coverage of public API
  - New tests checking various data-model properties and smells
- Improved scalability:
  - Provided lock-free implementation of ad_page_contract_filters and ad_page_contract_filter_rules. This change improves parallel processing of requests and is primarily interesting for sites with a few mio page views per days. These locks were among the most frequent nsv locks
  - Reduced locks on util_memoize_cache my more invariants values into per-thread caching (acs_lookup_magic_object, ad_acs_version, .... ) and by avoiding specialized calls, which can be realized by already optimized ones (apm_package_installed_p_not_cached ref-timezones was most frequently used util_memoize_cache entry). These changes are necessary to avoid full still-stand on the unfortunate long-time locks on util_memoize_cache stemming from permission and user management with wild-card flush operations, which require to iterate over all cache entries (which might be on a busy server several hundred thousands)
  - Added new interface for cache partitioning to reduce lock latencies on high load websites
  - Added new interface for lock-free per-thread and per-request caching to avoid scattered ad-hoc implementations
  - Better reuse of DB handles (reduced expiring/reopen/etc.), faster access to handles
- Improved startup time:
  - When the package acs-automated-testing is disabled, startup time is reduced by avoiding loading of support functions and tests; the size of the blueprint is reduced
  - xowf: loading of at-jobs is significantly improved.
- Security improvements:
  - Strengthened page contracts
  - CSP support for application packages
  - CSP fine tuning
- Better exception handling based on Tcl 8.6 exception handlers (try and throw, also available in Tcl 8.5)
  - Provided a new ad_try implementation based on Tcl's try replaces now the old ad_try, with_catch and with_finally, which are marked as deprecated
  - The new ad_try is in essence Tcl's try but with predefined handling of ad_script_abort and should be also used instead of catch, when the OpenACS API is used (which might use script aborts)
  - All core packages use the new ad_try instead of the deprecated versions.
- Connection close reform:
  - NaviServer/AOLserver continue after connection closing commands to execute a script. This is in many situations not desired, especially, when for the page as well a .adp file exists, which will try to deliver this on the already closed connection. This can lead to errors in the error.log file, which are sometimes hard to analyze
  - Due to this cleanup, developers should use in most such cases cases ad_script_abort
  - Connection closing commands are e.g. ad_returnredirect, ad_redirect_for_registration, cr_write_content, ad_page_contract_handle_datasource_error, ad_return_string_as_file, ad_return_complaint, ad_return_error, ad_return_forbidden, ad_return_warning, ad_return_exception_page, ns_returnredirect, ns_return, ns_returnerror
  - The new version has made on most occasions explicit, when the script should abort.
- API changes (new and extended API calls):
  - New API call category::get to obtain category description for a category_id and locale
  - New utility ad_pad emulating both lpad and rpad typically available in DBMSs
  - New proc lc_content_size_pretty, prettify data size given in bytes. It supports three different standards (SI base-10, IEC base-2 and the old JEDEC base-2), default is SI base-10.
  - New flag -export for ad_form: this flag uses export_vars under the hood and supports all of this API's features (e.g. :multiple, :sign, :array). This addresses a long standing TODO
  - util::pdfinfo: simple poppler-utils wrapper to extract pdf information
  - util::http: leverage new ns_http features such as request file spooling. Native implementation will now be used only on NaviServer >= 4.99.15.
  - Database API:
    - db_foreach: queries executed inside of a db_foreach will not be issued using a different handle and will therefore be safe to use in a transaction
    - db_list_of_lists: new -with_headers flag, which will make the first element of the returned list to be the column names as defined in the query
  - Groups API:
    - Logics to delete a group type have now been included in the API
    - Allow to filter group members by member_state in the API
- Deprecated commands:
  - Many deprecated API calls were included in the code (and sometimes still in use) sometimes more than 10 years after these calls have been deprecated. In case a site modification still uses deprecated code, the user is warned about this. The OpenACS 5.10 code base does not depend on deprecated code.
  - Move deprecated code into separate files
  - Made loading of deprecated code optional (can be controlled via parameter "WithDeprecatedCode" in section "ns_section ns/server/${server}/acs" of the config file. By default, deprecated procs are still loaded
  - When deprecated code is not loaded, the blueprint of the interpreter is smaller. The following number of lines of code can be omitted when loading without the deprecated procs:
    - acs-tcl: 3178
    - acs-templating: 450
    - xotcl-core http-client-procs: 830
    - acs-content-repository: 1717 (including .xql files)
- Bugfix and Code Maintenance:
  - Made sure all party emails are stored as lowercase through the API
  - Fixed long standing regression in template::list: we were looping through the list "elements", rather than the "display_elements". This prevents specifying different sets of columns to be returned depending on the -formats and -selected_format options in template::list::create.
  - acs-content-repository: New HEIC and HEIF mimetypes
  - acs-mail-lite: handle to_addr specified as "DisplayName <email>" without errors
  - Fixed invalidating of all existing user logins, (aka) "Logout from everywhere" feature, useful e.g. to make sure no device still holds a valid login when we change our password on a device
  - Don't lose the return URL when one tries to join a subsite before being logged in
  - Added doc(base_href) and doc(base_target) for setting <base> element via blank-baster (see issue #3435)
  - Groups:
    - When a new group is created, flush all the group::get_id caches with the same name so that the new group can be fetched correctly in case it replaces a previously deleted one
    - Cleanup message keys coming from groups in acs-translations when a group is deleted
  - acs-lang:
    - lang::util::convert_to_i18n: do not always register a en_US translation, which would be always overridden. Instead, let lang::message::register make sure that a en_US message exists and create one only as a fallback.
    - lc_time_fmt: leverage Tcl clock to address shortcomings such as handling of dates in Julian/Gregorian calendar and impossible dates such as 1999-02-29, implement missing formats, support previously undocumented formats explicitly
  - search: make sure objects in the search indexer queue still exist by the time they are swept by the indexer (e.g. items deleted before the indexer could sweep them)
  - attribute::delete: fix proc so it leverages stored procedure capability of dropping the database table as well
  - util::http: fix UTF-8 encoding issues for some cornercases
  - Localization: Complete Italian and Spanish localization for the whole .LRN set of packages (including themes). Message keys for new and previously localized packages have also been updated
- General cleanup/maintenance
  - Improved handling of server implementation-specific code: server-specific code can be optionally loaded via specifying the server family in the filename. Provided *-procs-aolserver.tcl and *-procs-naviserver.tcl similar to *.postgresql.xql and *.oracle.xql where appropriate
  - Modernization of Tcl idioms.
  - Compliance of files, proc names, ... to the naming conventions.
  - White space cleanup, indentation changes.
  - Improvement of public API documentation
  - Adjustment of proc protection levels (public, private)
  - Adjustment of log severity
  - Cleanup of obsolete files
  - Replacement of handcrafted forms by ad_form
  - Typo fixing
  - Editor hints
  - Replacement of deprecated calls
  - Addition of missing contracts
  - ...
- SQL cleanup:
  - Cleanup of obsolete nonportable SQL constructs in a way Oracle and PostgreSQL code base divergency is reduced:
    - "nvl" -> "coalesce"
    - "sysdate" / "now()" -> standard "current_date" or "current_timestamp"
    - Use standard-compliant "dual" table where appropriate (required by Oracle, supported by PostgreSQL)
    - Use non-dialectal cast idioms when appropriate
    - Adopt CTE idioms in Oracle codebase as well (e.g. connect -> with recursive)
    - ... (reference Oracle version will be 11gr2 as is oldest version officially supported by Oracle (See here and here)
  - Reduced superfluous .xql queries
    - acs-subsite: delete 21 files with un-referenced .xql queries
    - acs-tcl: delete 4 files
    - news: 3 files
    - file-storage: 1 file
    - dotlrn: 9 files
- New Packages:
  - cookie-consent: alerting users about the use of cookies on a website
  - boomerang: performance of your website from your end user’s point of view
  - xooauth: OAuth implementation, including LTI (Learning Tools Interoperability)
  - dotlrn-bootstrap3-theme: Bootstrap 3 theme for DotLRN
  - xowf-monaco-plugin: Integration of Monaco editor with for code exercise types in xowf
  - proctoring-support: utilities and user interfaces to implement proctoring of the user session, mainly intended in the context of distance education and online exams. The main proctoring feature relies only on web technologies and does not require any plugin or additional software. Optional support for the Safe Exam Browser has also been introduced. The package is currently at the core of WU Online Exam infrastructure and is integrated in the inclass exam implementation for xowf.
Require Tcl 8.6, XOTcl 2.1, PostgreSQL 9.6 (PostgreSQL 9.5 EOL: February 2021), tdom 0.9

OpenACS Version 5.9.1 Agenda

Refactoring of rich-text editor integration

Driving force: Debian packaging (e.g. js minified code is not allowed)
Moved out code from acs-templating, provided interfaces to add many different rich-text editors as separate packages
New OpenACS packages:
- richtext-xinha
- richtext-tinymce
- richtext-ckeditor4 (has ability to choose between CDN and local installation via web interface)

Improving admin interface

New theme manager:
- Goals:
  - Make it easier to keep track of themes with local modifications
  - Make it easier to create local modifications of existing themes and to update these
  - Show differences between default theme parameter (in DB) and actual settings (in subsite parameters)
  - Allow to delete unused themes
  - Give site admin hints, which theme is used at which subsite
  - Ease theme switching
- Added a subsite::theme_changed callback to be able to handle theme changes in custom themes (was also necessary for proper integration with DotLRN theming)
- Added support for these features under subsite admin (/admin/)
- Improved support for themed templates via [template::themed_template]
Improved (broken) interface to define/manage groups over web interface
Allow to send as well mail, when membership was rejected
New functions [membership_rel::get_user_id], [membership_rel::get] and [membership_rel::get_group_id] to avoid code duplication
Added support to let user include %forgotten_password_url% in self-registration emails (e.g. in message key acs-subsite.email_body_Registration_password)
Improved subsite/www/members
- Make it possible to manage members of arbitrary groups
- Improved performance for large groups
- Improved configurability: when ShowMembersListTo is set to "3", show list to members only, when this is not the whole subsite
Improved user interface for /admin/applications for large number of applications
Various fixes for sitewide-admin pages (under /acs-admin)
Update blueprint in "install from repository" (currently just working in NaviServer)

SQL

Further cleanup of .xql files (like what as done for acs-subsite in OpenACS 5.9.0):
- 36 files deleted
- Removed more than 100 obsolete named queries
- Stripped misleading SQL statements
Marked redundant / uncalled SQL functions as deprecated
Replaced usages of obsolete view "all_object_party_privilege_map" by "acs_object_party_privilege_map"
Removed type discrepancy introduced in 2002:
- acs_object_types.object_type has type varchar(1000), while
- acs_object_types.supertype has type varchar(100)
- ... several more data types are involved, using acs_object_types.object_type as foreign key
Simplified core SQL functions by using defaults:
- Number of functions reduced by a factor of 2 compared to OpenACS 5.9.0 (while providing compatibility for clients using old versions),
- Reduced code redundancy
- Affected functions:
  - Reduced content_item__new from 12 versions to 6,
  - Reduce content_revision__new from 7 to 4
  - Similar in image__new, image__new_revision, content_item__copy, content_item__get_title, content_item__move
- PostgreSQL 9.5 supports named parameter in the same syntax as in Oracle. Further reduction of variants will be possible, once OpenACS requires at least PostgreSQL 9.5
Reduced usage of deprecated versions of SQL functions (mostly content repository calls)
Reduced generation of dead tuples by combining multiple DML statements to one (reduces costs of checkpoint cleanups in PostgreSQL)
Permission queries:
- Improved performance
- Support PACKAGE.FUNCTION notation for PostgreSQL to allow calls permission queries exactly the same way as in Oracle (e.g. "acs_permission.permission_p()"). This helps to reduce the number of PostgreSQL specific .xql files.
Modernized SQL:
- Use real Boolean types instead of character(1)
  (done for new-portal, forums, faq, attachments, categories, dotlrn, dotlrn-forums, evaluation)
- Use real enumeration types rather than check constraints (done for storage_type text/file/lob)

CR hygienics (reduce cr bloat)

Provided means to avoid insert/update/delete operations in the search queue:
OpenACS adds for every new revision often multiple entries to the search_queue, without providing any means to prevent this. This requires for busy sites very short intervals between queue sweeps (otherwise too many entries pile up). Another consequence is that this behavior keeps the PostgreSQL auto-vacuum daemons permanently active. Many of these operations are useless in cases where the content repository is used for content that should not be provided via search. The changed behavior should honors a publish-date set to the future, since it will not add any content with future publish dates to the search-queue.
Reduced number of insert cr_child_rels operations, just when needed:
cr_child_rels provide only little benefit (allow one to use roles in a child-rel), but the common operation is a well available in cr_items via the parent_id. cr_child_rels do not help for recursive queries either. One option would be to add an additional argument for content_item__new to omit child-rel creation (default is old behavior) and adapt the other cases.

Security improvements

Added support against CSRF (cross site request forgery)
- OpenACS maintains a per-request CSRF token that ensures that form replies are coming just from sites that received the form
- CSRF support is optional for packages where CSRF is less dangerous, and such requests are wanted (e.g. search and API-browser)
Added Support for W3C "Upgrade-Insecure-Headers" (see https://www.w3.org/TR/upgrade-insecure-requests/):
For standard compliant upgrade for requests from HTTP to HTTPS
Added support for W3C "Subresource Integrity" (SRI; see https://www.w3.org/TR/SRI/)
Added support for W3C "Content Security Policy" (CSP; see https://www.w3.org/TR/CSP/)
- Removed "javascript:*" links (all such urls are removed from the 90 packages in oacs-5-9, excluding js libraries (ajaxhelper) and richtext code)
- Removed "onclick", "onfocus", "onblur", "onchange" handlers from all .adp and .tcl files in the 90 packages in oacs-5-9 (excluding js libraries (ajaxhelper) and richtext code)
- Added optional nonces to all <script> elements with literal JavaScript content
Removed "generic downloader", which allowed to download arbitrary content items, when item_id was known (bug-fix)
Improved protection against XSS and SQL-injection (strengthen page contracts, add validators, added page_contract_filter "localurl", improve HTML escaping, and URI encoding)
Fixed for potential traversal attack (acs-api-documentation-procs)

Improvements for "host-node mapped" subsites

Fixed links from host-node mapped subsite pages to swa-functions (must be always on main subsite)
Made "util_current_directory" aware of host-node-mapped subsites
Added ability to pass "-cookie_domain" to make it possible to use the same cookie for different domains
Fixed result of affected commands "util_current_location", "ad_return_url", "ad_get_login_url" and "ad_get_logout_url" for HTTP and HTTPS, when UseHostnameDomainforReg is 0 or 1.
Improved UI for host-node maps when a large number of site nodes exists

Reform of acs-rels

Made acs-rels configurable to give the developer the option to specify, whether these are composable or not (default fully backward compatible). This is required to control transitivity in rel-segments
The code changes are based on a patch provided by Michael Steigman.
For details, see:
- https://openacs.org/forums/message-view?message_id=4031049
- https://openacs.org/forums/message-view?message_id=5330734

Improved status code handlers for AJAX scenarios

Don't report data source errors with status code 200 (use 422 instead)
Let "permission::require_permission" return forbidden (403) in AJAX calls (determined via [ad_conn ajaxp])

Improved Internationalization

Extended language catalogs for
- Russian (thanks to v v)
- Italian (thanks to Antonio Pisano)
- Spanish (thanks to Hector Romojaro)
- German (thanks to Markus Moser)
Added (missing) message keys
Improved wording of entries
Added message keys for member_state changes, provide API via group::get_member_state_pretty

Improved online documentation (/doc)

Fixed many broken links
Removed fully obsolete sections
Improved markup (modernize HTML)
Updated various sections

Misc code improvements:

18 issues from the OpenACS-bug-tracker fixed
Made code more robust against invalid/incorrect input (page_contracts, validators, values obtained from header fields such as Accept-Language)
Fixed quoting of message keys on many places
Improved exception handling (often, a "catch" swallows one to much, e.g. script_aborts), introducing "ad_exception".
Generalized handling of leading zeros:
- Fixed cases where leading zeros could lead to unwanted octal interpretations
- Switch to use of " util::trim_leading_zeros" instead of "template::util::leadingTrim", "dt_trim_leading_zeros" and "template::util::leadingTrim", marked the latter as deprecated
URL encoding
- "ad_urlencode_folder_path": new function to perform an urlencode operation on the segments of the provided folder path
- "export_vars": encode path always correctly, except -no_base_encode is specified
- Fixed encoding of the URL path in "ad_returnredirect"
Improvements for "ad_conn":
- Added [ad_conn behind_proxy_p] to check, whether the request is coming from behind a proxy server
- Added [ad_conn behind_secure_proxy_p] to check, whether the request is coming from behind a secure proxy server
- Added [ad_conn ajax_p] to check, whether the request is an AJAX requests (assumption: AJAX request sets header-field Requested-With: XMLHttpRequest")
- Added [ad_conn vhost_url] to obtain the url of host-node-mapped subsites
Added various missing upgrade scripts (missing since many years) of changes that were implemented for new installs to reduce differences between "new"-and "old" (upgraded) installations
Templating
- Get rid of various pesky "MISSING FORMWIDGET: ...formbutton:ok" messages
- Improved support for javascript event handlers in template::head
- New functions "template::add_event_listener" and "template::add_confirm_handler"
- Fix handling, when "page_size_variable_p" is set (was broken since ages)
Improved location and URL handling:
- Refactored and commented "util_current_location" to address security issues, handle IPv6 addresses, IP literal notation, multiple drivers, "
- Improved "security::get_secure_location" (align with documentation)
- New functions:
  - "util::configured_location"
  - "util::join_location", "util::split_location"
  for working on HTTP locations to reduce scattered regexps handling URL components
- Improved IPv6 support
- Use native "ns_parseurl" when available, provide backward compatible version for AOLserver
MIME types:
- Added more Open XML formats for MS-Office to allowed content types
- Modernized entries to IANA recommendations
- New function "cr_check_mime_type" centralizing the retrieval of the mime_type from uploaded content
Finalized cleanup of permissions (started in OpenACS 5.9.0):
- Get rid of "acs_object_context_index " (and therefore on "acs_object_party_privilege_map " as well) on PostgreSQL.
  Reasons:
  - huge table,
  - expensive maintenance, used only in a few places,
Misc new functions:
- "lang::util::message_key_regexp": factor out scattered regexp for detecting message keys
- "ns_md5" and "ns_parseurl": improve compatibility between AOLserver and NaviServer
- "ad_dom_sanitize_html": allow one to specify different sets of tags, attributes and protocols and "ad_dom_fix_html", which is a light weight tidy variant.
Improved HTML rendering (acs-api-browser), provide width and height to speed up rendering
Improved ADP files (e.g. missing doc(title))
Added usage of "ad_include_contract" on more occasions
Modernize Tcl and HTML coding
Reduced dependency on external programs (use Tcl functions instead)
Improved robustness of "file delete" operations all over the code
Improved documentation, fix demo pages
Aligned usages of log notification levels (distinction between "error", "warning" and "notice") with coding-standards
Cleaned up deprecated calls:
- Removed usage of deprecated API functions (e.g. "cc_lookup_email_user", "cc_email_from_party", "util_unlist", ...)
- Moved more deprecated procs to acs-outdated

OpenACS Version 5.8 Agenda

PostgreSQL 9.2+:
- Get rid of nonstandard backslash escapes in function definitions
- Change quote syntax in SQL files (single quotes around the functions) to recommended PostgreSQL quoting using (recommended since pg8.0, jan 2005). li>Drop aliases in favor of named function arguments (recommended since pg8.0)
- Fix wrong function_args, add missing function_args, align default semantics with the defaults in pg (providing "null" as default means the argument is optional)
- Make OpenACS loadable without any tweaks in the pg config files
Use recursive queries for e.g. permission lookup to avoid performance problems in pg 8.4 and newer)
ADP: Use byte-compiled function wherever possible in compiled adp-code, support "@var;literal@" when neither quotes nor localization is needed in compiled adp-code
Improve support of NaviServer
Switch to Tcl 8.5 (TIP #143)
Improve scalability: Reduce mutex-stress on util-memoize cache and for cache maintenance in general
Code cleanup:
- Get rid of calls to deprecated code (e.g. ad_tables, ad_parameter, ... in acs-core and main packages)
- Improve awareness of usage of deprecated code (complain to error.log)
- Use Tcl 8.5 idioms
- cleanup of various http-client approaches and introduce a common implementation util::http::get and util::http::post; get rid of other usages, mark these as deprecated
- page-contracts: Perform checking of all ids in acs-core and main packages to improve error messages and to improve security
OpenACS 5.8.1 should be released with main packages

OpenACS Version 5.7 Agenda

Support for object management in core

Documentation improvements as discussed at the Guatemala conference:
- Make current openacs.org/test-doc source for static files included in the release and provide ease means to achieve this for the release manager
  - DONE (CVS HEAD): Provide in XoWiki an alternative table of contents by nested UL/LI (without JavaScript) for static output
  - DONE (CVS HEAD): Provide in XoWiki a prototype page similar to "book" without edit-buttons etc., using the new table of contents
- Update openacs.org/test-doc where necessary (incomplete list):
  - DONE: Fix the page ordering for the higher chapters (the original document had no 3rd. level numbering)
  - update pages in /test-doc which are more recent in openacs/xowiki
  - bump version numbers of OpenACS, where appropriate (some places talk about openacs-5-0, others about openacs-5-1, oacs-5-2-3rc1 or 5-3)
  - some version numbers of the required components are quite a mess. e.g. some parts say that Postgres 7.3 is required, some examples talks about postgres 7.4.7 and 8.2.4 in the same listing.
  - also the dotlrn version numbers are old dotrln-2.0
  - Tcl version numbers should be 8.4.19
  - The install section for XOTcl is missing in II.3.4

Release Status

Development is taking place in the oacs-5-10 branch.

OpenACS Version 5.10.0 Agenda/wish list

Postponed for later releases:
- Implement subsite-singleton (in addition to the classical singleton)
- Say farewell to CVS
- Make more parts of xotcl-core a first-class citizen of the OpenACS core (e.g. database interface)
- Data bloat hygiene:
  - Rethink package parameter and portlet parameter data models
  - Parameters: include "subsite-parameters" in parameter resolution (package->subsite->global)
Functional improvements
- Features:
  - Added additional page_contract filter: oneof(red|green|blue)
  - template::add_event_listener and template::add_confirm_handler now can target elements by CSS selector
  - Added text/markdown to the accepted text formats or rich-text widget
  - Support for range types in .xql files:
    PostgreSQL supports range types since 9.5. When using range types, square braces have to be used in SQL statements. Since OpenACS uses always Tcl substitution in .xql files, and OpenACS does NOT allow backslash substitution in these files, square brackets could not be escaped and therefore not be used in .xql files so far. This change allows now a developer to deactivate the substitution by passing e.g. "-subst none" to the db_* command using the .xql file. Valid values for "-subst" are "all", "none", "vars", and "commands", default is "all" which is exactly the behavior of before. Therefore, this change is fully backward compatible.
  - New API call "category::get" to obtain category description for a category_id and locale
  - Added doc(base_href) and doc(base_target) for setting <base> element via blank-baster (see issue #3435)
  - Improved API browser: Visualization for code dependencies (which procs calls what, from where is a proc being called) and test-coverage
  - Warn site administrators about expiring certificates
  - Content repository: New HEIC and HEIF mimetypes
  - New utility ad_pad emulating both lpad and rpad typically available in DBMSs
  - New proc lc_content_size_pretty, prettify data size given in bytes. It supports three different standards (SI base-10, IEC base-2 and the old JEDEC base-2), default is SI base-10.
  - Database API:
    - db_foreach: queries executed inside of a db_foreach will not be issued using a different handle and will therefore be safe to use in a transaction
    - db_list_of_lists: new -with_headers flag, which will make the first element of the returned list to be the column names as defined in the query
  - Groups:
    - Logics to delete a group type have now been included in the API
    - Allow to filter group members by member_state in the API
  - ad_form:
    - new input types:
      - checkbox_text
      - color
      - email
      - tel
      - url
      - number
      - file (multiple)
      - h5date and h5time: date and time fields using native HTML5 visualization and input normalization
    - -export flag: this flag now uses export_vars under the hood and therefore support all of this API's features (e.g. :multiple, :sign, :array). This addresses a long standing TODO
  - Registry for .js and .css libraries: allow besides classical URLs symbolic names for loading external resources (e.g. jquery), this makes it easier to upgrade libraries in multiple packages (without running into problems with duplicate versions) and supports switching between CDN and local pathsURN.
    The existing implementation is based on URNs and extends the existing template-head API to support registration for URNs. A URN provides an abstraction and a single place for e.g. updating references to external resources when switching between a CDN and a locally stored resource, or when a resource should be updated. Instead of adding e.g. a CDN URL via template::head::add_script, one can add an URN and control its content from a single place. Use common namespaces for OpenACS such as urn:ad:css:* and urn:ad:js:*.
    - Register URNs:
      Example provider (e.g. in some theme):
```
   template::register_urn \ 
       -urn urn:ad:js:jquery \ 
       -resource /resources/xowiki/jquery/jquery.min.js
```
    - The registered URN can be used like classical URL after registration.
      Example consumer:
```
   template::head::add_javascript -src urn:ad:js:jquery
```
    - Declare composite files: Provide an interface to define that a .js file or a .css file contains multiple other .js/.css files in order to reduce the number of requests.
```
   template::head::includes -container urn:js::style.js -parts {urn:ad:js:jquery ...}
```
  - Improved support for streaming HTML: The new API function template::collect_body_scripts can be used to get the content of template::script or CSP calls (template::add_body_script, template::add_event_listener, template::add_body_handler, template::add_script) when streaming HTML (incremental HTML) is used. Before, these call could bot be used for streaming HTML
  - util::pdfinfo: simple poppler-utils wrapper to extract pdf information
- Reforms:
  - Dynamic blueprint reloading:
    - When reloading apm packages, watched files, etc. the NaviServer blueprint is now updated correctly. This solves the long-standing problem that changes for scheduled procedures required a restart of the server. Furthermore, the old-style reloading was based on a ever-growing list of reload operations each time a new reload was requested, causing slow-downs in long running server instances, especially, when new threads are started.
    - Now changes are applied to all NaviServer threads, including threads for
      schedules procedures, ns_jobs and the like. Note that the current job has to be finished before the changes can be applied.
    - For the transition, it is possible to switch between the classical reloading style and blueprint reloading by changing a variable in acs-tcl/tcl/apm-procs.tcl
  - Login:
    - Get rid of bugging "login page expired" messages. The 17 years old construct was replaced by newer means to avoid caching of form values from the login form. Admins of existing sites should set the kernel parameter "LoginPageExpirationTime" to 0
  - Forums:
    - Removed hard-coded dependency with registered_users group when checking forum permissions
    - Don't rely so heavily on acs_permissions to model forum configuration, as this can have unexpected consequences in convoluted multi-group/multi-subsite scenarios. Prefer simpler table attributes instead
    - New style of attachments to the forums, allowing multiple attachments to a single message directly from the message post page, using the multiple file input widget. Retain compatibility with old style attachments, using the new 'AttachmentStyle' package instance parameter. Currently, this supports two values: 'simple' (new behavior) and 'complex' previous behavior.
  - Chat:
    - Revamping of the GUI
    - Responsiveness
    - Full screen mode
    - Skins support (minimal, classic and bubbles, included): Skins are located in the new /packages/xowiki/www/resources/chat-skins/ directory. New skins can be created by just adding the css and js files in the skins directory, and naming them accordingly (chat-$SKIN_NAME.{js|css}).
    - Avatars (can be enabled per room)
    - Number of active users in chat
    - Tab notifications of new messages
    - Web Notifications:
      - https://www.w3.org/TR/notifications/
      - https://developer.mozilla.org/en-US/docs/Web/API/Notifications_API/Using_the_Notifications_API
  - acs-lang:
    - admin pages:
      - Added the option to unregister (delete permanently the message key from all locales) a message key that has been already marked as deleted. Useful for cleaning up old message keys.
      - Added the option to undelete, using the new ::message::undelete proc.
      - Made number and category (untranslated/deleted/...) of messages coherent in all pages.
      - Added the columns 'total' and 'deleted' to the index page.
    - object_id reference: it is now possible to associate a message key to an object_id in a way that e.g. when the object is deleted, so is the message key. This addresses cases such as the message keys generated by group creation or by the new XoWiki localized fields
  - Notifications:
    - When sending a notification on behalf of a person, if the system is not configured to process replies to notification, do not set the reply-to address to anything different than the sender
  - User/Person/Party API: rework and rationalize caching of all party, person and user API, create separate caches for each of these types, make the API and return dicts. acs_user::get will not fail anymore with non-existing user.
  - User Portrait: created API to retrieve and create, store and delete the user's portrait. Also address leftover child relationships from the past and delete them properly.
  - util::http: leverage new ns_http features such as request file spooling. Native implementation will now be used only on Naviserver >= 4.99.15.
- Bugfixes:
  - Made sure all party emails are stored as lowercase through the API
  - Fixed long standing regression in template::list: we were looping through the list "elements", rather than the "display_elements". This prevents specifying different sets of columns to be returned depending on the "-formats" and "-selected_format" options in template::list::create.
  - acs-mail-lite: handle to_addr specified as "DisplayName <email>" without errors
  - Fixed invalidating of all existing user logins, (aka) "Logout from everywhere" feature, useful e.g. to make sure no device still holds a valid login when we change our password on a device
  - Don't lose the return URL when one tries to join a subsite before being logged in
  - Notifications: proper cleanup of acs_objects resulting from the deletion of dynamic notification requests
  - Groups:
    - When a new group is created, flush all the group::get_id caches with the same name so that the new group can be fetched correctly in case it replaces a previously deleted one
    - Cleanup message keys coming from groups in acs-translations when a group is deleted
  - acs-lang:
    - lang::util::convert_to_i18n: do not always register a en_US translation, which would be always overridden. Instead, let lang::message::register make sure that a en_US message exists and create one only as a fallback.
    - lc_time_fmt: laverage tcl clock to address shortcomings such as handling of dates in Julian/Gregorian calendar and impossible dates such as 1999-02-29, implement missing formats, support previously undocumented formats explicitly
  - search: make sure objects in the search indexer queue still exist by the time they are swept by the indexer (e.g. items deleted before the indexer could sweep them)
  - attribute::delete: fix proc so it leverages stored procedure capability of dropping the database table as well
  - util::http: fix UTF-8 encoding issues for some cornercases
- New Packages:
  - cookie-consent: alerting users about the use of cookies on a website
  - boomerang: performance of your website from your end user’s point of view
  - xooauth: OAuth implementation, including LTI
  - dotlrn-bootstrap3-theme: Bootstrap 3 theme for DotLRN
  - xowf-monaco-plugin: Integration of Monaco editor with for code exercise types in xowf
  - proctoring-support: utilities and user interfaces to implement proctoring of the user session, mainly intended in the context of distance education and online exams. The main proctoring feature is relies only on web technologies and does not require any plugin or additional software. Optional support for the Safe Exam Browser has also been introduced. The package is currently at the core of WU Online Exam infrastructure and is integrated in the inclass exam implementation for XoWf
Non-functional Changes
- Improved regression testing
  - Goal is that all packages in oacs-5-10 pass regression test
  - Include web testing in standard regression testing
  - Introduced new test authentication authority, allowing to run many user administration tests outside the context of a "real authority": in cases where the real authority depends on external services to proof identity, (e.g. Kerberos), those tests would just fail.
  - Introduce the display of warnings in the UI
  - Added test coverage information in the automated testing pages, using the new proc-coverage API and providing test coverage information for packages and system wide.
  - Increased overall coverage of public API
  - New tests checking various data-model properties and smells
- Improved scalability:
  - Provided lock-free implementation of ad_page_contract_filters and ad_page_contract_filter_rules. This change improves parallel processing of requests and is primarily interesting for sites with a few mio page views per days. These locks were among the most frequent nsv locks
  - Reduced locks on util_memoize_cache my more invariants values into per-thread caching (acs_lookup_magic_object, ad_acs_version, .... ) and by avoiding specialized calls, which can be realized by already optimized ones ("apm_package_installed_p_not_cached ref-timezones" was most frequently used util_memoize_cache entry). These changes are necessary to avoid full still-stand on the unfortunate long-time locks on util_memoize_cache stemming from permission and user management with wild-card flush operations, which require to iterate over all cache entries (which might be on a busy server several hundred thousands)
  - Added new interface for cache partitioning to reduce lock latencies on high load websites
  - Added new interface for lock-free per-thread and per-request caching to avoid scattered ad-hoc implementations
  - Better reuse of DB handles (reduced expiring/reopen/etc.), faster access to handles
- Improved startup time:
  - When the package acs-automated-testing is disabled, startup time is reduced by avoiding loading of support functions and tests; the size of the blueprint is reduced
  - xowf: loading of at-jobs is significantly improved.
- Security improvements:
  - Strengthened page contracts
  - CSP support for application packages
  - CSP fine tuing
- Better exception handling based on Tcl 8.6 exception handlers ("try" and "throw", also available in Tcl 8.5)
  - Provided a new "ad_try" implementation based on Tcl's "try" replaces now the old "ad_try", "with_catch" and "with_finally", which are marked as deprecated
  - The new "ad_try" is in essence Tcl's "try" but with predefined handling of "ad_script_abort" and should be also used instead of "catch", when the OpenACS API is used (which might use script aborts)
  - All core packages use the new "ad_try" instead of the deprecated versions
- Connection close reform:
  - NaviServer/AOLserver continue after connection closing commands to execute a script. This is in many situations not desired, especially, when for the page as well a .adp file exists, which will try to deliver this on the already closed connection. This can lead to errors in the error.log file, which are sometimes hard to analyze
  - Due to this cleanup, developers should use in most such cases cases "ad_script_abort"
  - Connection closing commands are e.g. ad_returnredirect, ad_redirect_for_registration, cr_write_content, ad_page_contract_handle_datasource_error, ad_return_string_as_file, ad_return_complaint, ad_return_error,
    ad_return_forbidden, ad_return_warning, ad_return_exception_page, ns_returnredirect, ns_return, ns_returnerror
  - The new version has made on most occasions explicit, when the script should abort.
- SQL cleanup:
  - Cleanup of obsolete nonportable SQL constructs in a way Oracle and PostgreSQL code base divergency is reduced:
    - "nvl" -> "coalesce"
    - "sysdate" / "now()" -> standard "current_date" or "current_timestamp"
    - Use standard-compliant "dual" table where appropriate (required by Oracle, supported by PostgreSQL)
    - Use non-dialectal cast idioms when appropriate
    - Adopt CTE idioms in Oracle codebase as well (e.g. connect -> with recursive)
    - ... (reference Oracle version will be 11gr2 as is oldest version officially supported by Oracle (See here and here)
  - Reduced superfluous .xql queries
    - acs-subsite: delete 21 files with un-referenced .xql queries
    - acs-tcl: delete 4 files
    - news: 3 files
    - file-storage: 1 file
    - dotlrn: 9 files
- Deprecated commands:
  - Move deprecated code into separate files
  - Made loading of deprecated code optional (can be controlled via parameter "WithDeprecatedCode" in section "ns_section ns/server/${server}/acs" of the config file. By default, deprecated procs are still loaded

OpenACS Version 5.9.1 Agenda

Refactoring of rich-text editor integration

Driving force: Debian packaging (e.g. js minified code is not allowed)
Moved out code from acs-templating, provided interfaces to add many different rich-text editors as separate packages
New OpenACS packages:
- richtext-xinha
- richtext-tinymce
- richtext-ckeditor4 (has ability to choose between CDN and local installation via web interface)

Improving admin interface

New theme manager:
- Goals:
  - Make it easier to keep track of themes with local modifications
  - Make it easier to create local modifications of existing themes and to update these
  - Show differences between default theme parameter (in DB) and actual settings (in subsite parameters)
  - Allow to delete unused themes
  - Give site admin hints, which theme is used at which subsite
  - Ease theme switching
- Added a subsite::theme_changed callback to be able to handle theme changes in custom themes (was also necessary for proper integration with DotLRN theming)
- Added support for these features under subsite admin (/admin/)
- Improved support for themed templates via [template::themed_template]
Improved (broken) interface to define/manage groups over web interface
Allow to send as well mail, when membership was rejected
New functions [membership_rel::get_user_id], [membership_rel::get] and [membership_rel::get_group_id] to avoid code duplication
Added support to let user include %forgotten_password_url% in self-registration emails (e.g. in message key acs-subsite.email_body_Registration_password)
Improved subsite/www/members
- Make it possible to manage members of arbitrary groups
- Improved performance for large groups
- Improved configurability: when ShowMembersListTo is set to "3", show list to members only, when this is not the whole subsite
Improved user interface for /admin/applications for large number of applications
Various fixes for sitewide-admin pages (under /acs-admin)
Update blueprint in "install from repository" (currently just working in NaviServer)

SQL

Further cleanup of .xql files (like what as done for acs-subsite in OpenACS 5.9.0):
- 36 files deleted
- Removed more than 100 obsolete named queries
- Stripped misleading SQL statements
Marked redundant / uncalled SQL functions as deprecated
Replaced usages of obsolete view "all_object_party_privilege_map" by "acs_object_party_privilege_map"
Removed type discrepancy introduced in 2002:
- acs_object_types.object_type has type varchar(1000), while
- acs_object_types.supertype has type varchar(100)
- ... several more data types are involved, using acs_object_types.object_type as foreign key
Simplified core SQL functions by using defaults:
- Number of functions reduced by a factor of 2 compared to OpenACS 5.9.0 (while providing compatibility for clients using old versions),
- Reduced code redundancy
- Affected functions:
  - Reduced content_item__new from 12 versions to 6,
  - Reduce content_revision__new from 7 to 4
  - Similar in image__new, image__new_revision, content_item__copy, content_item__get_title, content_item__move
- PostgreSQL 9.5 supports named parameter in the same syntax as in Oracle. Further reduction of variants will be possible, once OpenACS requires at least PostgreSQL 9.5
Reduced usage of deprecated versions of SQL functions (mostly content repository calls)
Reduced generation of dead tuples by combining multiple DML statements to one (reduces costs of checkpoint cleanups in PostgreSQL)
Permission queries:
- Improved performance
- Support PACKAGE.FUNCTION notation for PostgreSQL to allow calls permission queries exactly the same way as in Oracle (e.g. "acs_permission.permission_p()"). This helps to reduce the number of PostgreSQL specific .xql files.
Modernized SQL:
- Use real Boolean types instead of character(1)
  (done for new-portal, forums, faq, attachments, categories, dotlrn, dotlrn-forums, evaluation)
- Use real enumeration types rather than check constraints (done for storage_type text/file/lob)

CR hygienics (reduce cr bloat)

Provided means to avoid insert/update/delete operations in the search queue:
OpenACS adds for every new revision often multiple entries to the search_queue, without providing any means to prevent this. This requires for busy sites very short intervals between queue sweeps (otherwise too many entries pile up). Another consequence is that this behavior keeps the PostgreSQL auto-vacuum daemons permanently active. Many of these operations are useless in cases where the content repository is used for content that should not be provided via search. The changed behavior should honors a publish-date set to the future, since it will not add any content with future publish dates to the search-queue.
Reduced number of insert cr_child_rels operations, just when needed:
cr_child_rels provide only little benefit (allow one to use roles in a child-rel), but the common operation is a well available in cr_items via the parent_id. cr_child_rels do not help for recursive queries either. One option would be to add an additional argument for content_item__new to omit child-rel creation (default is old behavior) and adapt the other cases.

Security improvements

Added support against CSRF (cross site request forgery)
- OpenACS maintains a per-request CSRF token that ensures that form replies are coming just from sites that received the form
- CSRF support is optional for packages where CSRF is less dangerous, and such requests are wanted (e.g. search and API-browser)
Added Support for W3C "Upgrade-Insecure-Headers" (see https://www.w3.org/TR/upgrade-insecure-requests/):
For standard compliant upgrade for requests from HTTP to HTTPS
Added support for W3C "Subresource Integrity" (SRI; see https://www.w3.org/TR/SRI/)
Added support for W3C "Content Security Policy" (CSP; see https://www.w3.org/TR/CSP/)
- Removed "javascript:*" links (all such urls are removed from the 90 packages in oacs-5-9, excluding js libraries (ajaxhelper) and richtext code)
- Removed "onclick", "onfocus", "onblur", "onchange" handlers from all .adp and .tcl files in the 90 packages in oacs-5-9 (excluding js libraries (ajaxhelper) and richtext code)
- Added optional nonces to all <script> elements with literal JavaScript content
Removed "generic downloader", which allowed to download arbitrary content items, when item_id was known (bug-fix)
Improved protection against XSS and SQL-injection (strengthen page contracts, add validators, added page_contract_filter "localurl", improve HTML escaping, and URI encoding)
Fixed for potential traversal attack (acs-api-documentation-procs)

Improvements for "host-node mapped" subsites

Fixed links from host-node mapped subsite pages to swa-functions (must be always on main subsite)
Made "util_current_directory" aware of host-node-mapped subsites
Added ability to pass "-cookie_domain" to make it possible to use the same cookie for different domains
Fixed result of affected commands "util_current_location", "ad_return_url", "ad_get_login_url" and "ad_get_logout_url" for HTTP and HTTPS, when UseHostnameDomainforReg is 0 or 1.
Improved UI for host-node maps when a large number of site nodes exists

Reform of acs-rels

Made acs-rels configurable to give the developer the option to specify, whether these are composable or not (default fully backward compatible). This is required to control transitivity in rel-segments
The code changes are based on a patch provided by Michael Steigman.
For details, see:
- https://openacs.org/forums/message-view?message_id=4031049
- https://openacs.org/forums/message-view?message_id=5330734

Improved status code handlers for AJAX scenarios

Don't report data source errors with status code 200 (use 422 instead)
Let "permission::require_permission" return forbidden (403) in AJAX calls (determined via [ad_conn ajaxp])

Improved Internationalization

Extended language catalogs for
- Russian (thanks to v v)
- Italian (thanks to Antonio Pisano)
- Spanish (thanks to Hector Romojaro)
- German (thanks to Markus Moser)
Added (missing) message keys
Improved wording of entries
Added message keys for member_state changes, provide API via group::get_member_state_pretty

Improved online documentation (/doc)

Fixed many broken links
Removed fully obsolete sections
Improved markup (modernize HTML)
Updated various sections

Misc code improvements:

18 issues from the OpenACS-bug-tracker fixed
Made code more robust against invalid/incorrect input (page_contracts, validators, values obtained from header fields such as Accept-Language)
Fixed quoting of message keys on many places
Improved exception handling (often, a "catch" swallows one to much, e.g. script_aborts), introducing "ad_exception".
Generalized handling of leading zeros:
- Fixed cases where leading zeros could lead to unwanted octal interpretations
- Switch to use of " util::trim_leading_zeros" instead of "template::util::leadingTrim", "dt_trim_leading_zeros" and "template::util::leadingTrim", marked the latter as deprecated
URL encoding
- "ad_urlencode_folder_path": new function to perform an urlencode operation on the segments of the provided folder path
- "export_vars": encode path always correctly, except -no_base_encode is specified
- Fixed encoding of the URL path in "ad_returnredirect"
Improvements for "ad_conn":
- Added [ad_conn behind_proxy_p] to check, whether the request is coming from behind a proxy server
- Added [ad_conn behind_secure_proxy_p] to check, whether the request is coming from behind a secure proxy server
- Added [ad_conn ajax_p] to check, whether the request is an AJAX requests (assumption: AJAX request sets header-field Requested-With: XMLHttpRequest")
- Added [ad_conn vhost_url] to obtain the url of host-node-mapped subsites
Added various missing upgrade scripts (missing since many years) of changes that were implemented for new installs to reduce differences between "new"-and "old" (upgraded) installations
Templating
- Get rid of various pesky "MISSING FORMWIDGET: ...formbutton:ok" messages
- Improved support for javascript event handlers in template::head
- New functions "template::add_event_listener" and "template::add_confirm_handler"
- Fix handling, when "page_size_variable_p" is set (was broken since ages)
Improved location and URL handling:
- Refactored and commented "util_current_location" to address security issues, handle IPv6 addresses, IP literal notation, multiple drivers, "
- Improved "security::get_secure_location" (align with documentation)
- New functions:
  - "util::configured_location"
  - "util::join_location", "util::split_location"
  for working on HTTP locations to reduce scattered regexps handling URL components
- Improved IPv6 support
- Use native "ns_parseurl" when available, provide backward compatible version for AOLserver
MIME types:
- Added more Open XML formats for MS-Office to allowed content types
- Modernized entries to IANA recommendations
- New function "cr_check_mime_type" centralizing the retrieval of the mime_type from uploaded content
Finalized cleanup of permissions (started in OpenACS 5.9.0):
- Get rid of "acs_object_context_index " (and therefore on "acs_object_party_privilege_map " as well) on PostgreSQL.
  Reasons:
  - huge table,
  - expensive maintenance, used only in a few places,
Misc new functions:
- "lang::util::message_key_regexp": factor out scattered regexp for detecting message keys
- "ns_md5" and "ns_parseurl": improve compatibility between AOLserver and NaviServer
- "ad_dom_sanitize_html": allow one to specify different sets of tags, attributes and protocols and "ad_dom_fix_html", which is a light weight tidy variant.
Improved HTML rendering (acs-api-browser), provide width and height to speed up rendering
Improved ADP files (e.g. missing doc(title))
Added usage of "ad_include_contract" on more occasions
Modernize Tcl and HTML coding
Reduced dependency on external programs (use Tcl functions instead)
Improved robustness of "file delete" operations all over the code
Improved documentation, fix demo pages
Aligned usages of log notification levels (distinction between "error", "warning" and "notice") with coding-standards
Cleaned up deprecated calls:
- Removed usage of deprecated API functions (e.g. "cc_lookup_email_user", "cc_email_from_party", "util_unlist", ...)
- Moved more deprecated procs to acs-outdated
- Marked remaining (and unused) "cc_*" functions as well as deprecated.
Improved Oracle and windows support
Fixed common spelling errors and standardize spelling of product names all over the code (comments, documentation, ...)
Many more small bug fixes

OpenACS Version 5.8 Agenda

PostgreSQL 9.2+:
- Get rid of nonstandard backslash escapes in function definitions
- Change quote syntax in SQL files (single quotes around the functions) to recommended PostgreSQL quoting using (recommended since pg8.0, jan 2005). li>Drop aliases in favor of named function arguments (recommended since pg8.0)
- Fix wrong function_args, add missing function_args, align default semantics with the defaults in pg (providing "null" as default means the argument is optional)
- Make OpenACS loadable without any tweaks in the pg config files
Use recursive queries for e.g. permission lookup to avoid performance problems in pg 8.4 and newer)
ADP: Use byte-compiled function wherever possible in compiled adp-code, support "@var;literal@" when neither quotes nor localization is needed in compiled adp-code
Improve support of NaviServer
Switch to Tcl 8.5 (TIP #143)
Improve scalability: Reduce mutex-stress on util-memoize cache and for cache maintenance in general
Code cleanup:
- Get rid of calls to deprecated code (e.g. ad_tables, ad_parameter, ... in acs-core and main packages)
- Improve awareness of usage of deprecated code (complain to error.log)
- Use Tcl 8.5 idioms
- cleanup of various http-client approaches and introduce a common implementation util::http::get and util::http::post; get rid of other usages, mark these as deprecated
- page-contracts: Perform checking of all ids in acs-core and main packages to improve error messages and to improve security
OpenACS 5.8.1 should be released with main packages

OpenACS Version 5.7 Agenda

Support for object management in core
Postgresql 9.0
TinyMCE update (fix for random JS injection issue, affecting Safari)
Fix for "remember me" issue
WCAG2-AA

OpenACS Version 5.6 Agenda

global parameters
package "embeds"
fix search by package_id
core works on Postgresql 8.4

OpenACS Version 5.5 Agenda

DONE: Postgresql 8.3 support: especially regarding tsearch2
DONE: acs-authentication:
- fix upgrade, add conditional logic into site wide tcl library so that you can login to perform the rest of the upgrade
DONE: tinymce:
- upgrade to 3.1.1 + language packs
- HTML Strict cleanup
- create appropriate parameters for its config in acs-templating
acs-mail-lite:
- DONE: cleanup duplicated procs (bounce)
- review the parsing of bouncing messages (case user_id 0)
- DONE: rollout support
Documentation improvements as discussed at the Guatemala conference:
- Make current openacs.org/test-doc source for static files included in the release and provide ease means to achieve this for the release manager
  - DONE (CVS HEAD): Provide in XoWiki an alternative table of contents by nested UL/LI (without JavaScript) for static output
  - DONE (CVS HEAD): Provide in XoWiki a prototype page similar to "book" without edit-buttons etc., using the new table of contents
- Update openacs.org/test-doc where necessary (incomplete list):
  - DONE: Fix the page ordering for the higher chapters (the original document had no 3rd. level numbering)
  - update pages in /test-doc which are more recent in openacs/xowiki
  - bump version numbers of OpenACS, where appropriate (some places talk about openacs-5-0, others about openacs-5-1, oacs-5-2-3rc1 or 5-3)
  - some version numbers of the required components are quite a mess. e.g. some parts say that Postgres 7.3 is required, some examples talks about postgres 7.4.7 and 8.2.4 in the same listing.
  - also the dotlrn version numbers are old dotrln-2.0
  - Tcl version numbers should be 8.4.19
  - The install section for XOTcl is missing in II.3.4
  - remove ChangeLog from documentation
  - find some other prominent place for the ChangeLog
  - Fix indenting in examples (e.g. in Rocael's robust web development framework)
  - overthink Win2000 guidelines. There are the native compiled packages from Maurizio, including everything from postgres, xotcl ....
- It is desired to find a single person responsible for overworking the documentation, however, funding is unclear.

Future

Split Xinha and TinyMCE into separate packages see: https://openacs.org/forums/message-view?message_id=2750958
Usability ("my account" page)
XHTML ?
Testing and documentation for recording automated tests using the firefox plugin and the upload feature for it new in automated testing. Probably needs some polishing and should be talked to with Quest who are getting into this.
Parameter Scope Patch https://openacs.org/bugtracker/openacs/patch?patch%5fnumber=845
Remove obsolete master template stuff (default and site master template in openacs-4/www, acs-subsite's group-master, and related CSS and images). Probably in the version which follows 5.5 (probably 5.6). Also remove the compat master stuff at the same time.
