Roadmap
dev repo [bitbucket.org]
ChangeLog

Main Focus: UTF-8 support and migration and PHP 8.0 compatibility

R6.0 is more or less R5.5 with Unicode support. Please look here for open issues from R5.5 .

1.1. PHP

• https://wiki.php.net/rfc/void_return_type

1.1.1. PHP 7.4

1. https://www.php.net/manual/en/migration74.php
2. "Trying to access array offset on value of type ..." warning for accessing null/bool/int/float/resource as if it were an array -> bugs:553

1.1.2. PHP 8.0

1. https://stitcher.io/blog/new-in-php-8
2. https://php.watch/versions/8.0
3. https://github.com/php/php-src/blob/php-8.0.0/UPGRADING

1.2. Features

• UTF-8 support – Migration to Unicode

1.3. Core

1. https://github.com/rectorphp/r[...]rview.md#codequality
2. localize date formats
3. improve and foster message sets
4. set return type declarations : (array | bool | float | int | mixed | string | void | ... )
   • http://docs.php.net/manual/en/[...]returning-values.php
5. fix client side JS input validation patterns, see below under testing
   1. login and registration action DONE
   2. new, clone and rename handler
6. Replace all HTML-Entities except HTML special chars
   1. nbsp; — to indent or add extra spacing to a paragraph, sentence, or another portion, better using CSS instead of multiple non-breaking spaces.
7. add option to disable hit counter
8. move link and notifications functions in own class
   • $this->msg->notify_user()
   • $this->ref->link()

1.4. Installer

1. validate username
2. Nginx: installer seems to activate rewrite_mode ?
3. define('CACHE_SESSION_DIR', '/tmp'); is defined in constant.php, and currently not set via the installer
   1. use ini_get('session.save_path') as indicator, BUT we do not use the PHP build in session! -> write value, its a nuisance that the user currently has to do this on his own
4. offer to create the recovery_password within the install process
5. use dbal also for installer: $db->sql_query($sql)

1.5. Handler

• auto-save function on the edit and _comments handler by applying the localStorage function
• saved discarded comment due invalidated token to avoid data loss
• send notice on comment edit and make change visible in actions like it is done for pages, to not miss possible important content changes
• increase the default size of the comment textarea in the default theme
• add option to send a copy of the personal message also to the sender
• edit: set custom textarea size (user settings/JS)
• properties: add page tag below page title: Tag: Cluster/Page – looks ugly
• wordbreak, how to break lines of Chinese, Japanese, or Korean

  • line-break: strict;
    white-space: nowrap;
    word-break: keep-all; 

1.6. Action

• registration: add white and blacklist for allowed email domains
• poll: improve actions and add templates

1.7. Formatter

• add support for AVIF – GD lib support pending!
  • https://developer.mozilla.org/[...]ats/Image_types#AVIF
  • converter: https://avif.io/
  • https://caniuse.com/avif
• add lazy loading for <img> tags in wackoformatter and for thumbnails in gallery action
  • <img loading=lazy>
  • https://web.dev/browser-level-image-lazy-loading/
  • Do we want an option to turn it off, global, per user or device?

• str_replace("\xc2\xa0", " ", $string);

• text inside ##code formatter## is processed as wikitext with possibly undesired results
  • the text must be escaped to be taken as is
• removes intentional left empty lines inside info formatter
• parse also anchor with dash, e.g. tag#one-two
• ((../ Go Back)) goes back two levels, but should go to parent page only
• interwiki links are not tracked
• <ignore> tags must be removed for diff-mode 0
  • check output other than show handler, the replace should be done in one place
• relative links were not parsed in the context of the page they are included, what is the default behavior?
• re-parsing all pages and links may result in wrong toc references, when the included page gets parsed after the page which includes them
  • HOTFIX: save all included pages with wrong toc reference again, this will update body_toc

1.8. Cache

• set new default cache_ttl values in config default and description in documentation

  • seconds	duration
    600	10 minutes
    1200	20 minutes
    3600	1 hour
    7200	2 hours

SELECT cache_lang, method, count(cache_id) AS n 
FROM `prefix_cache` 
GROUP BY cache_lang, method 
ORDER BY `cache_lang`, n DESC, method;

1.9. Admin Panel

• support templates
• resync links excludes pages from owner System, we may remove this restriction
• restore: process may fail while restoring page with certain Unicode
  • needs further investigation, backup seems to works while restoring may fail
  • creates empty REPLACE queries for page table until it causes a script termination due timeout

2. add debug option to send error log into separate file + rotate logs
3. add IP block to ban bad actors, bots

2.4. M17

open issues (add)

   1. min_href()
   2. router.conf
   3. abandon standard_handlers (?)
3. Guide to build templates

7. relative time
   1. global / user setting
   2. where to use relative time and where not 
   3. different schemes
8. invalidate SQL and page cache (with common function) (?), which is also checking against config settings
9. add also footer after hard return, GUI consistency
10. how to check access privileges for a group, e.g. has_access() for $ -> moderate handler : locking
11. upload of file without extension -> broken
12. allow only common reasonable extensions for upload
    1. blacklist MIME types -> implement
    2. blacklist extension -> update
    3. white list
13. add notification for 
    1. new page -> Admin, Moderator, parent page owner
    2. new attachments
       1. -> to page: watchers, Admin, Moderator
       2. -> global: Admin, Moderator
14. add default max value in actions: news, blog, files, etc. -> use list_count as default
15. empty body_r after page rename/relocation -> page needs re-rendering
16. installer: rewrite_mode option ! – dysfunctional
17. redirect hashid url?
18. allow multi logins (on/off)
    1. add multi login warning: 'Jemand hat sich bereits an diesem Konto angemeldet'

20. add array for 'default' AND 'user' menu so both can used independently (create/edit menu sets)
21. rewrite_mode setting in AP is pointless if it is overwritten in Setting class

2.5. Fix

1. invalidate / purge only a sub set of the SQL cache (?), do we always need to purge the entire cache?
2. check formatting of log() function -> html / wacko formatting
3. use common list count setting per user + use it as default in lists for paging
4. check for avoidable SQL roundtrip queries
   1. e.g. translit: href() -> mini_href() -> slim_url() -> translit() ($this->config['multilanguage'] == true) -> load_page()
   2. fix additional round trips gaining page_id in combination with has_access() and link() function (tag <-> page_id)
      1. options: use object cache or pass variable page_id via link() function:
         • // cache page_id for for has_access validation in link function
         • $this->page_id_cache[$page['tag']] = $page['page_id'];
      2. part 1: revision:f5f2295a85b9
   3. add object for extending and array with default pages (accessible via theme) to preload_link() function
      1. -> ensure pre caching to avoid single lookup per intralink in DB on each page call
      2. -> parse also page path for bread crumbs in page_link table
5. link() -> default: $anchor_link – should only active inside page_body (?)
   • additional check if its better to prefix the id="doc.deutsch.konfiguration"
     • to avoid unintentional mix with CSS settings
   • set anchor id only where needed, minimizes also size of attributes
6. add option help to action to show all parameters in a info box 
   1. echo 'show all available parameters with description'
7. broken list in tree action if levels changes not in order – e.g. depth 1.2 -> depth 2.4
   1. show missing levels
8. search?phrase="sourceforge.net" -> paging fails with "term to search"
9. bug: news action takes all subpages – is this desired?
10. improve search (open since ages), add some measures to improve relevance (time, size, user, filter, ...) and provide more and better meta data for search results
11. add options to show/hide page related categories at the page bottom
    • themes may overwrite these settings via $this->config['footer_tags'] = OFF
    • allways ON as default for posts in the forum cluster
    • do we need an additional option for the user?
12. get translation
    1. put lang-strings for action and handlers into separate dynamically loadable lang-files
    2. cache
13. audit comments, moderation handler
14. replace p tag in toc action -> avoid wrong p in p 
15. Form in preview breaks Edit / Preview form -> produces nested form -> filter?
16. revisit access right settings for forum posts and menu access
    1. the menu won't show the page properties icon -> annoying
17. syntax
    1. table header
       • /Dev/NewFeatures/SyntaxForTableHeader
       • add check button to WikiEdit for table headers
       • match syntax so it is possible to set TH per cell and not only per row
18. implement rating hack (but without mandatory JS)
    1. https://www.youtube.com/watch?v=orPVEAipz2A
19. add unique log message key to filter events (messages may differ)
20. use deleted field to mark deleted pages, comments, files
    • basics implemented for page and files
    • open: rollback/restore procedure and handling of final deletion
      
21. disable global upload for users
    1. only local
    2. only for cluster
22. add regex for this->config['users_page']/[*]/
    • Yet the engine does not validate the namespace for the user cluster, so that nobody can create a page under /User except his own [UserName]
    • Then we can disallow random pages for the first level in the users cluster except the own [UserName].
    • The register action creates this page usually for the user.

2.6. Notifications

1. Notifications

2.6.1. Notice digest

• store events notices and compile digest for user [user|moderator|admin]
  • new user
  • comments
  • files
  • changes

2.7. Handler

1. clone entire cluster is only available for Admins atm., it should also available for ...
2. improve global upload settings
   1. allow groups
   2. set individual rights (only images, quota, etc. for a user, group)
3. send page as email (like print)
4. show: add option 'Flag as Spam/Inappropriate'
5. show: Delayed Indexing delay_index
   • <meta name=“robots” content=“noindex,nofollow”>
6. see upload subpage
   1. upload: check if the MIME type of the uploaded file matches the file extension
      1. https://www.owasp.org/index.ph[...]stricted_File_Upload
      2. https://www.acunetix.com/websitesecurity/upload-forms-threat/
      3. https://www.php.net/manual/en/[...]n.exif-read-data.php
   2. upload: add form field to chose another file name (?)
   3. upload: add accept attribute depending on config settings https://www.w3.org/TR/html5/fo[...]ml#attr-input-accept
   4. upload: send a notify mail on upload DONE
7. add meta handler namespace ['page', 'account', 'file', 'service']

   • This is the simplest way to standardize document locations and for the language-independent single instances of service pages, like login. Next step is the separated cluster for those pages, linked with prefix, for example, ((service:login)).

   • this can be easily done with the new URI router
   • handler/account/
8. file: apply access restrictions for global files if Wiki is closed -> $
   1. add and enforce global Wiki mode, minimum access rights
   2. route global files only for registered users

4. Wacko is spamming BRs, in between everything
5. add option to hide protected links
   • You must login to see this link. Register now, if you have no user account yet.
6. Error: Bad value 4 for attribute type on element ol.
   1. see $new_indent_type in wackoformatter -> error prone

      •   1. hallo
            5. should not take the number but 1, same for i, I, a, A

   2. Block elements inside inline elements
   3. http://www.w3.org/TR/html5/gro[...]nt.html#attr-ol-type
7. allow case insensitive matching of file links, e.g. File:image.jpg
8. breaks quote

   <[http://www.example.com]>

9. ((image.jpg)) shows images from image/ folder ???
10. <[ ]> eats blank line in quote, undesired

   2. user approval
   3. event log 
   4. Bad Behavior
4. upload module

   1. PAY ATTENTION TO SECURITY RISKS
       
      
      Before adding random file/MIME types: please think about possible security issues.
      
      For example HTML (.htm, .html), JavaScript (.js) and PHP (.php) file are types you’d better avoid as they can be “executed” on your server where you really would not want that to happen. For most of these kind of files, this should not be a problem though as these files are better off being compressed into a ZIP file anyway.
      
      Only add file types that you REALLY need and that you are comfortable with.

5. user management
   • deactivate / delete inactive users
     • criteria
     • actions
6. add module to filter, moderate and manage pages, comments, (files)
   1. see modules for content like pages

       <col span="1" style="width: 5%;">
       <col span="1" style="width: 5%;">
       <col span="1" style="width: 45%;">
       <col span="1" style="width: 15%;">
       <col span="1" style="width: 10%;">
       <col span="1" style="width: 10%;">
     </colgroup>

   •  <thead class="data-head">
             <tr class="">
             </tr>
             [...]
         </thead>
     
     <tbody id="table-section-one">
     [...]
     </tbody>
     
     <tbody id="table-section-two">
     [...]
     </tbody>

2.12. Database

1. https://www.digitalocean.com/c[...]ur-mysql-5-7-upgrade
2. /Dev/Guidelines/SQL/SQLmodes

2.12.1. Check for SQL STRICT mode violations

1. Using GROUP BY and selecting an ambiguous column
2. Inserting the non standard zero date into a datetime column
3. Inserting a 20 character string into a 10 character column
4. Division by zero
5. Inserting a negative value into an unsigned column

so far

1. #1406 – Data too long for column 'description' at row 1
   1. set HTML maxlength="DB_FIELDSIZE" for all (VAR)CHAR form field
      • suggested (JS hint – might differ in some cases – smaller, e.g. meta description 160, meta title 60) + database field size (mandatory enforcement)
      • JS hint: You have <strong>60</strong> characters left
   2. set PHP length check before passing to INPUT / UPDATE
2. #1055 – 'dev.g.group_name' isn't in GROUP BY

SELECT
`DIGEST_TEXT` AS `query`,
`SCHEMA_NAME` AS `db`,
`COUNT_STAR` AS `exec_count`,
`SUM_ERRORS` AS `errors`,
(ifnull((`SUM_ERRORS` / nullif(`COUNT_STAR`,0)),0) * 100) AS `error_pct`,
`SUM_WARNINGS` AS `warnings`,
(ifnull((`SUM_WARNINGS` / nullif(`COUNT_STAR`,0)),0) * 100) AS `warning_pct`,
`FIRST_SEEN` AS `first_seen`,
`LAST_SEEN` AS `last_seen`,
`DIGEST` AS `digest`
FROM
 performance_schema.events_statements_summary_by_digest
WHERE
((`SUM_ERRORS` > 0) OR (`SUM_WARNINGS` > 0))
ORDER BY
 `SUM_ERRORS` DESC,
 `SUM_WARNINGS` DESC;

2.13. WikiEdit

1. use only one popup for new link, having link and link description together
2. popup for tables

1. set table header
2. select color for text and highlighting
3. resize textarea
4. undo / redo
5. JavaScript search&replace
6. symbols

2.14. Usability issues

1. indicate page [language|permissions]
   1. permissions: use icon and different colors
2. add double-click support for editing comments
3. When should I use a select box instead of radio buttons?
   1. https://www.nngroup.com/articl[...]es-vs-radio-buttons/
4. Not indicating an active form field
   • e.g.

     textarea:focus {
         border: 1px solid red; }

   • You can use the ‘:focus’ selector on lots of elements, but it’s super handy when used on inputs and textareas to indicate that the field is active. Add CSS styling such as a highlighted border, or a subtle change to the background color.
5. forms with checkboxes and options in lists
   • e.g. category handler or users in admin panel
   • assignment of form buttons
6. usage of new page handler
   • seen in many fresh installs, users adding sub pages to HomePage/subpage
     • this is possible but is it really desired and understood, should we filter out system pages as pre-provided cluster in the /new [page] handler?
7. make name spaces for users and groups more intuitive accessible
   1. users/nickname/userspace/..
   2. groups/usability/groupspace/..
8. add ability to easily create groups and to add group members
   1. suggestions?
9. GUI inconsistencies
   1. handler
   2. actions
   3. message boxes

2.15. Extensions

• https://github.com/google/code-prettify

2.16. Refactoring

2.17. Staging Area

1. blog action (will replace news action)
2. snippet action
3. forum, topics action
4. Admin Panel
   1. refactor -> antipatterns
   2. bad behaviour module
   3. list and check each module, assign status

2.18. Ideas

1. spam / badword handling -> bad_words($text) function
   1. https://en.wikipedia.org/wiki/Wordfilter
   2. https://stackoverflow.com/ques[...]ood-profanity-filter
   3. What you need is a good way for users to flag inappropriate content and a mechanism to deal with it swiftly. One way is to automatically hide/remove content if it's been flagged more than X times.
2. rel="edit" -> https://tools.ietf.org/html/rfc686
3. enforce ACL-Policy, e.g. set read to $, user can't overwrite the setting
4. test PHPThumb alternatives

2.19. Themes

1. new mobile ready theme / layout? -> on hold (we got a new template engine!)
   • https://getbootstrap.com/

Flexbox vs Grid

1. Flexbox: content dictates layout
2. Grid: container dictates layout (to some extent)

Flexbox is great, it just isn't the best thing for overall page layouts.
Flexbox and grid play well together, and are a huge step forward from the float & table hacks they replace. The sooner we can use them both in production, the better.

CSS Varibles

1. https://developer.mozilla.org/[...]/Using_CSS_variables

.gimme-columns {
	columns: 20em 3;
	column-count: 3;
	column-width: 20em;
}

.sticky {
  position: sticky;
  top: 0;
}
