Friendica Support reshared this. database data seems corrupt

!Friendica Support

It seems like I do have a problem with my database :-( .

The database ran full about a year ago (what a shame, I know :( ...) and I had to recover some of the data (otherwise I had to import a backup about ~12hours ago, I tried to avoid to loose posts for this period of time for my users ...). So I stopped it, started it with innodb_force_recovery=3, repaired it and checked it with mysqlcheck.

Two days ago, I updated the mariadb from 1.10.3 to 1.10.10 and now the problems occur again.

I stopped the MariaDB 1.10.3 container, updated it to 1.10.10 and started it again .. And MariaDB started a "crash recovery". I really don't know why... The crash recovery wasn't successfully (I tried it ~4 times), so I had to add innodb_force_recovery=3 again.

Now the database went up, but everytime I stopped it and started it again, the crash recovery appears again.

So after the instance was up and running, I dumped the whole database with mysqldump into one single *.sql , started a brand new MariaDB 1.10.10 and imported the dump again.

So far so good ..

But... unfortunately, after a restart, the crash recovery appears again. So I'm totally lost, what's now happening..

I noticed during the import that one batch of rows took about 2 hours to complete with the result query affected 0 rows.

here's my customized.cnf, which I'm using (it's a Hetzner root server with 64 GB RAM and 12 CPUs):
query_cache_size = 0
query_cache_type = 0
performance_schema = ON
join_buffer_size = 140M
innodb_buffer_pool_size = 12G
innodb_log_buffer_size = 31M
innodb_log_file_size = 3G
table_open_cache = 1000
max_connections = 400
wait_timeout = 200
interactive_timeout = 4000

log-bin = mysqld-bin
transaction-isolation = READ-COMMITTED
binlog-format = ROW
skip-innodb-read-only-compressed = ON
innodb_read_only_compressed = OFF
innodb_use_native_aio = OFF


For the new MariaDB instance, I didn't add any customization to avoid any wrong options.

currently, it makes a recovery again:

Questions about /display/

!Friendica Developers

@Michael Vogel - I'm currently moving the mod/display.php

As far as I can see, there are two main-routes for this controller:

  • /display/{guid}
  • /display/feed-item/{uri-id}.atom[/conversation.atom]

and as far as I can say, it would be better if the second route should have an own root, like `dfrn_item/{uri-id}[/conversation.atom`, as it's a DFRN only logic.
Am I right so far?

If so, can I move it to this new path or is this path necessary for the federation usage, means it could be called from other servers too?
I just found calls with prefix DI::baseUrl(), so I guess it's "just" for the server itself, but I'm not sure ...

Friendica Developers reshared this.

@Michael Vogel / @Hypolite Petovan

I still struggle at mod/update_display.php
It's the only place, where the display_content from mod/display.php is called with the parameter $update = true.

But I don't find any place inside Friendica, where we call /update_display?p=<profile_uid>.

Do you know if this is till in use and if so, what's the meaning of it?
If we wouldn't use it anymore, there's a lot of code at mod/display.php, which I could delete in that case..

API usage for Friendica Frontend

!Friendica Developers

And another question :-)

Currently, we strictly separate between API calls and the Frontend.
But, Why?

I'm currently moving the events to the Module directory.
And there's already an API for it, but as far as I understand @Michael Vogel , we must not mix API and Frontend.

But as far as I know, in modern environments, there's a backend part (= API), and a frontend part (= view)
The own frontend still uses the same API. So we don't have to implement the same business logic at different places. As I said, I came across at Event, where this issue produces significant double-code.

So at least what I would like (in a final state :-):

  • API ... Create, Update, Delete, Get, GetMultiple for our Data model, or "everything without HTML output"
  • Module ... Everything, which produces HTML output :-)

I know, this would be a BIG change :-)

Friendica Developers reshared this.

In modern environments the frontend is calling the API. We are not there yet.

I would like having that separation since this would allow us to just test all API calls to make sure that the frontend is working as expected.

Friendica Developers reshared this.

@Michael Vogel
What is the showstopper for that? Cause that is also a thing for a new Webdesign. So The Web sould be separate from the code with all the magic.
@Philipp Holzer

Friendica Developers reshared this.

API is a misnomer in our case because it can designate several things:
- Our internal API (what you described in your post)
- The Twitter API endpoints we support
- The Mastodon API endpoints we support
- The GNU Social API endpoints we support
- The Friendica-specific API endpoints we expose (mainly for Friendiqa)

We definitely lack a unified internal API but thatโ€™s supposed to be taken care of by the Repository/Factory/Model/Entity structure that we should keep expanding.
This entry was edited (3 months ago)

Friendica Developers reshared this.

@Hypolite Petovan
why don't separate the api for Twitter, Mastodon, Gnu etc. and of course an api to communicate with the frontend.
No mixing the api together. Activateing the maybe Mastodon APi as main class with subclasses in one folder and subfolders.

@Philipp Holzer @Michael Vogel
This entry was edited (3 months ago)

Friendica Developers reshared this.

So far weโ€™ve done a good job at having the business code identical for the Twitter and Mastodon API endpoints. There are some legacy Friendica endpoints (mostly the asynchronous endpoints used by Javascript) that are redundant with the page modules.

Friendica Developers reshared this.

@Hypolite Petovan
Can this endpoint not be closed and moved to an other area. So that you have the main friendica core who will do the internal magic. On the other hand the API section who is communicating with the core. Additional an internal API who is communicating with the core and the frontend section. On all APIs there is only data communication.

The Frontend Section is an additional area who will communicate with the frontend API and the user.
So the magic on the frontend section will be created only in the frontend and the API communication will only send data ... No html, no Jscript and no other magic.

In that case all three sections (Core, API, Frontend) could be developed separate with less interference between them.

Sure if you need a new function... First core the API and if needed then frontend
@Philipp Holzer @Michael Vogel

Friendica Developers reshared this.

I don't think we need to go that far. Separating the web frontend from the API would be a massive undertaking at this point, and also there's a trend where even Javascript frontends are starting to request already formed HTML from the backend because it turns out it's faster this way. Which means we're both behind and ahead of the curve!

However we do need to extract the business logic in a unique place so that we can reference it from the places it is duplicated.

Friendica Developers reshared this.

@Hypolite Petovan
I think this is very necessary.
Passing preformatted web content makes you very inflexible since you have to go directly to the core. That's where I see the problem, that you either have a good coder for the core but not a good designer. The other way round a designer of the frontend can't write a good core code.
For this reason the Smarty framework is currently running in Friendica, which as I understand the framework wants to separate this.

If you want to speed up the whole thing, you have to get away from PHP code which is executed at runtime and create static pages. Peppered with lots of javascript which offloads/executes the execution to the client.

But ok that's my opinion on the subject.

@Philipp Holzer @Michael Vogel

Roland Häder reshared this.

Friendica Developers reshared this.

Thankfully, we can have both HTML modules and API endpoints! As long as we don't duplicate business code, which is what Philipp has been encountering.

On the other hand, writing a full Javascript web frontend is a massive endeavor, there currently are almost 500 web frontend routes that each represent a part of a Friendica feature. They all would need to have a Javascript counterpart, without even counting the corresponding bespoke API endpoints that would need to be created.
I think I've learned something here.

Add-on refactoring

!Friendica Developers

So this are my first thoughs about the Addons:

  • Metadata about each add-on should be in an extra file, I would prefer something like addon.json
  • I would like to replace the whole Hook class with a proper Registration class, which is loaded when activating the Add-on. So we can remove the whole Hook table.
  • All Events in Friendica should be in an events.config.php with a proper description (maybe as constants?)
  • for legacy purpose, I would create a wrapper class like the LegacyModule class, which would execute the corresponding php-functions
  • I'm thinking about a giving each Event a specific interface (not knowing how tbh currently, maybe the corresponding interface setting as a value for the Event inside the events.config.php?), so each event and each add-on will know exactly what parameters and which result is necessary

This is it so far..

I would like to start with creating the events.config.php and replace all text with constants.. I think this is a non invasive behaviour, but gives some insights about the next steps

Friendica Developers reshared this.

Like always this is kind of foggy for me :-) But I guess it will be a good idea to implement it in parallel to the current mechanism and then to move the addons step by step.

Du you have got an idea how to keep the folder structure in a way that all addons will stay in the addon folder?

Friendica Developers reshared this.

The folder structure wonโ€™t change, but instead of a list of functions, addons will become classes.

Friendica codebase restructure

!Friendica Developers

Based on the PR

@Hypolite Petovan is right, I should have started this conversation first, but it made fun to restructure our code, so it is what it is *gg*

What's the issue/my pain:

I'm thinking about introducing the PSR-7 Request/Response interfaces and create an Emitter, so there's no way out anymore directly inside the code, everything is done by the emitter. With this pattern, we could add all the authentication stuff inside a "Middleware" and get rid of the different auth-places (App, Security\Authentication, Module\BaseApi)

So, now I tried to think where to start. We would need a Middleware directory for all the auth/base-load things, but we already do have a mix of domain-based directories (TowFactorAuth), functionallity based directories (Model/Object/Factory/Collection/Capabilities) and and core directories (Core, App, Console, Worker)...

And I try to start to "really" encapsulate the domain-based directories inside Friendica\Library, so we get rid of some mixings, having all domain based classes inside one directory.

In the end, I think we should have some core directories at src, directing everyone to the right place.

I hope I didn't loose you at least, I just wrote down my path to this PR :)

PS: there're "just" ~200 code changes, the rest is because of the messages.po recreation don't worry :)

Friendica Woodpecker / CI in GitHub bricked

!Friendica Developers

I'm sorry, I bricked the CI with the latest Woodpecker change.. Now instead that we don't create Archives at all nodes, we now don't execute some pipelines at all and they are "stuck forever" and blocking new executions.

I'm not sure if I can fix it today, so here's the announcement :-/

I will kick the pipelines from time to time to make PR checks possible, but the "merge" pipelines aren't working (so no new archive appears currently..)
This entry was edited (3 months ago)

Friendica Developers reshared this.

I think I got it! :)

It was a mix of wrong environment variable setup for $WOODPECKER_LABELS (added additional " for the value, which got escaped and added to the value) and using the `label` filter in Woodpecker, not knowing that this feature is only in the nightly builds yet

--> as far as I can see, all Archives are now deployed at as expected :)

Yet another Git-Repo :D

@Tobias - I'd like to commit changes for the computed "docs" page at

Can you create this repo for me and make me admin for it? Thx :-)

!Friendica Developers

Hi, I'd like to add a new domain `` where we store the whole documentation. It should be versioned, like for the docs of the stable 2022.09 version or for the docs of the develop branch.

I think it would be possible to automatically generate it.

But before, I do need the domain - pinging @Michael Vogel - and a routing to the current vm-instance - pinging @utzer ~Friendica~ :-)

I'd like to generate it automatically during the CI, so the update would be smooth and automatically :-)

@Philipp Holzer @Michael Vogel @utzer ~Friendica~ Oh, even manuals are being updated and searchable. Now it is time to put links into #Friendica code. URL:<branch>/ or only for develop?

I don't have currently that time, so it's still WIP .. When it's finished, of course there will be a sub-dir for stable releases and develop - and Release candidates, similar to our branch structure :)

2 Factor & DB plaintext

!Friendica Developers

Hi all, I lost my mobile phone during the last festival and so my TOTP-App was gone forever. Unfortunately, I wasn't aware of my recovery codes, so I thought I would have to reset my accounts of Friendica.

But no! just use select code from 2fa_recorvery_codes where uid = 66 and used is NULL; and voilรก, I used the first code and was back in.

@Hypolite Petovan , isn't this a possible security issue, is it?? Storing such sensible data as plaintext. I think we should save it as hash like for passwords to make it impossible to read it again .. Yes, the downside is that there's no possibility to save recovery_codes from the settings-panel again, but tbh I feel a little bit unsafe, but maybe it's just a feeling :-)

Friendica Developers reshared this.

We hash passwords not just because we want to prevent someone having a database dump from logging in the website depending on this database, but also for the other websites users might use the same password for. There is no such risk for randomly generated recovery codes.

Additionally, the use of the recovery codes necessitates the use of the password (that you still had in your head/password manager), after all it's a second-factor authentication, which means that it can be freely compromised as long as the first factor (the password) is safe.

Still, we can hash these codes and as a result only show them once, it isn't that hard other than requiring someoneโ„ข to spend some quality time on this task.

Large database

!Friendica Admins
Hi everyone,

last week, I struggled with the size of my database for .. It went full (80GB) .. I added additional 10GB to the volume, but it seems to constantly increase and I think in a few weeks, I will be at the same situation like the last week.

Is there a possibility to shrink the database, or to wipe old data?
I recently deleted about 1.200 spam accounts (and set the register option to approval first ... lessons learned...). Are there leftovers inside the db which I can delete?

It's not that I don't have enough space, but I'm afraid of my backup borg-backup space in the near future ^^

nope, there're no active relays "Das System hat derzeit keinerlei Relays abonniert."

Disable the avatar cache in the admin settings. The avatar cache is most likely the biggest table in your database. Also enable a maximum lifetime for posts (See the performance section in the admin settings) with now around 5.000 users has da database size of around 100 GB.

haha, I think I will try to call her with that name and see what happens :D
What I did:

New Github/Gitea Label

!Friendica Developers
I'd like to introduce `Refactoring` as a new label. I feel like we should distinguish between "real" enhancements and "just" refactorings. What do you say?
I feel like most current issue labels are meaningless beyond the Bug label we use to prioritize issues during the RC period.

So it wouldnโ€™t do any harm to add another one, but it wonโ€™t help with any existing workflow either.
We never had any regression issue during refactoring tasks. ๐Ÿคฅ

Locks with hostname

!Friendica Developers
Calling @Hypolite Petovan and @Michael Vogel for support at

I do want to alter the way how locks are working to make parallel hosts/nodes possible. I think the logic itself is pretty straight forward and final.

BUT - how can I upgrade the lock table without using it during the update process itself, it's a gordon knot :-/
I think about using a new method at DBStructure: and execute it before using the lock.

Do you think it works? At least my local nodes are working, but I'm totally unsure about it yet ..

I'd like to finish this PR for 2021.12 as another preparation for making Friendica "cluster ready" :D
Any idea @Michael Vogel ? :) I'm really stuck here and it's one major piece in the puzzle to make Friendica cluster-ready ;-)
@Michael Vogel @Hypolite Petovan @Friendica Developers but wouldn't that possibly create a race condition, because a 2nd worker would start another update and wouldn't find the lock anymore so update it again?

Questions Depository

!Friendica Developers
Calling @Hypolite Petovan for help :-)

Why did you introduce a separate "Navigation" directory under "src"?

My guess: this is really a DDD practice using a directory for a use cases and define the different class-types under it (creating boundaries between differently purposed code). But if so, why don't you include the Modules/Notification as well?
And "Navigation/Notification" triggers for me, that the focus of this class is only the notifications at the top of the navbar, am I right?
I'm trying to follow your pattern and refactor the ProfileField / PermissionSet.

Would it be a new "src":
"src/Profile" , where PermissionSet and ProfileField are Entities/ValueObjects ? Or how would you structure these repositories/models?

Aaahh sounds like the "good old" Model View Controller (MVC) pattern:
- Model --> where the business logic is (=> Entity, Depository, ...)
- View --> the presentation layer (=> Renderer / smarty templates)
- Controller --> The logic to show the right business logic (glue between model & view) (=> Modules)
=> And I like it :-)

I'll give it a try after finishing the WebDav class ;-)
I didn't think in so many terms, but it looks like it, indeed!
I'm sorry, I'm mostly thinking that way ^^..

@Olaf It's still closed alpha (my node only :D )
@Olaf - If you want to try it --> the feature is integrated so you can find the addon now at the dev-branch :-)
Yes you can :-)

But Disclaimer: I was the only one who tested it yet, so please test it for your own before using it in production

A test Post from Friendica

Hi all, I'm trying to reach Twitter with my new Friendica Twitter plugin :-)
@Hypolite Petovan I got a lot of posts mirrored to my feed as well .. Do you know any other test for twitter plugin?
