    • add table: lang_link[page_id, lang, target_id]
  2. add debug option to send error log into separate file + rotate logs
  3. add IP block to ban bad actors, bots

3. M17

open issues (add)

  1. relative linking seems not working for ((../ back to parent page)), it links to root level (?!)
  2. add delimiter before page handler (_properties)
    1. min_href()
    2. router.conf
    3. abandon standard_handlers (?)
  3. Guide to build templates
  4. Permalink to page vs page version
  5. CSS does not get routed in RECOVERY_MODE
  6. relative time
    1. global / user setting
    2. where to use relative time and where not 
    3. different schemes
  7. invalidate SQL and page cache (with common function) (?), which is also checking against config settings
  8. add also footer after hard return, GUI consistency
  9. how to check access privileges for a group, e.g. has_access() for $ -> moderate handler : locking
  10. upload of file without extension -> broken
  11. allow only common reasonable extensions for upload
    1. blacklist MIME types -> implement
    2. blacklist extension -> update
    3. white list
  12. add default max value in actions: news, blog, files, etc. -> use list_count as default
  13. empty body_r after page rename/relocation -> page needs re-rendering
  14. installer: rewrite_mode option ! – dysfunctional
  15. allow multi logins (on/off)
    1. add multi login warning: 'Jemand hat sich bereits an diesem Konto angemeldet'
    2. This account is currently being used in 1 other location at this IP ().
  16. add access throttling feature
    • limit the number of page requests by a single IP address within a given time interval
  17. add array for 'default' AND 'user' menu so both can used independently (create/edit menu sets)
  18. rewrite_mode setting in AP is pointless if it is overwritten in Setting class

4. 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. check for avoidable SQL roundtrip queries
  4. 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
  5. add option help to action to show all parameters in a info box 
    1. echo 'show all available parameters with description'
  6. broken list in tree action if levels changes not in order – e.g. depth 1.2 -> depth 2.4
    1. show missing levels
  7. search?phrase="sourceforge.net" -> paging fails with "term to search"
  8. bug: news action takes all subpages – is this desired?
  9. 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
  10. 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?
  11. get translation
    1. put lang-strings for action and handlers into separate dynamically loadable lang-files
    2. cache
  12. audit comments, moderation handler
  13. replace p tag in toc action -> avoid wrong p in p 
  14. revisit access right settings for forum posts and menu access
    1. the menu won't show the page properties icon -> annoying
  15. implement rating hack (but without mandatory JS)
    1. https://www.youtube.com/watch?v=orPVEAipz2A
  16. add unique log message key to filter events (messages may differ)
  17. use deleted field to mark deleted pages, comments, files
    • basics implemented for page and files
    • open: rollback/restore procedure and handling of final deletion
  18. disable global upload for users
    1. only local
    2. only for cluster
  19. 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.

5. Notifications

  1. Notifications

5.1. Notice digest

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

6. 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

7. Action

  1. template toc and tree

8. Formatter

  1. Search Highlighter
  2. (/Users/WikiAdmin UserSpace | WikiAdmin)) -fails on |

  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 ???

    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
  7. recovery mode: CSS and images won't load
    • index.php: (!$db->ap_mode && RECOVERY_MODE) excludes static files!
      • !$db->ap_mode
  8. purge logs (TRUNCATE)
    1. log table
    2. referrers
    3. badbehavior
  9. use collgroup for col span % width 
    • <colgroup>
  <col span="1" style="width: 10%;">
  <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>

10. Database

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

10.1. 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;

11. 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?

    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

14. Themes


  1. new mobile ready theme / layout -> on hold (we got a new template engine!)
  2. https://developers.google.com/web/fundamentals/
  3. https://www.w3.org/Style/Examples/007/leaders

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
  2. https://www.w3.org/TR/css-variables/

CSS colums for index <div class="gimme-columns"><ul>

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

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

default theme

  • change blockquote
    • box-shadow: 0 0 6px rgba(0, 0, 0, 0.5);
  • add option to hide $this->config['site_name'] in theme header, e.g.: To Do R5.5 – WackoWiki -> To Do R5.5
  • min-height: 200px for .article, #page
