Getting E_NOTICE on develop branch

I'm getting this error message when I click on the lock icon:

Michael Vogel Friendica (AP)
This addon is unsupported and is about to be removed in future versions of Friendica.
Okay, thank you. :-) But is there any (mostly "protocol-technical") reason?
Michael Vogel Friendica (AP)
It cannot work that way.

Latest develop fails to run SQL update

@Friendica Developers I have an error while the db update was running, Friendica was sending me an email about it.
The friendica developers released update 1274 recently,
but when I tried to install it, something went terribly wrong.
This needs to be fixed soon and I can't do it alone. Please contact a
friendica developer if you can not help me on your own. My database might be invalid.
The error message is
Errors encountered performing database changes: ALTER IGNORE TABLE `item` DROP INDEX `contactid_allowcid_allowpid_denycid_denygid`, DROP INDEX `uid_authorlink`, ...


On console I get this error:
Error 1296 occurred during database update:
Got error 64 'Temp file write failure' from InnoDB


I'm now back at my old commit so the instance can work again.

"Infinite" scroll need overworking

When the small "addon" is enabled, more content is being loaded when users scroll down. So far so good. But if they scroll more down, more is being added to the DOM document which results in a growing browser procress and a slow-down due to the device has to handle more content.

I would prefer that the content in opposite scroll direction is being removed to allow smooth usage of the device (desktop PCs with low RAM will suffer greatly). If the user changes scroll direction, again content on the opposite direction is being removed.
browser bug friendica infinite-scroll slow-down
Maybe there is somewhere a #jquery #plugin around? Then we don't need to re-invent the wheel ...
Yesterday I had a look at the jquery plugins you mentioned. https://github.com/pixelcog/parallax.js is not about infinite scrolling. It is about to have a prallax effect. And https://github.com/fredwu/jquery-endless-scroll doesn't do that much more than our implementation already do (OK it can load previous pages).

The problem isn't to load next or previous pages through ajax. That would be very simple.

The problems we would have to deal with are:

  • which posts belong e.g. to page 1 (which should be removed from the screen when we scroll e.g from page 2 to page 3)
  • how do we deal with the situation when new posts arrive (e.g. the user would be on page 3 - a new post does arrive, and he/she scrolls to page 4 - I guess in this situation the first post of page 4 would be missing)
  • how do we deal with comments on posts (wich would move the post on top of the first place



The whole topic is very complex. I think this is not something which is easy to implement. I don't want to say that it is unsolvable, I just want to highlight that this "extended" infinite scrolling is more than just adding and removing content
Just using a request parameter, like "page" is not helpful, then you will may see duplicate posts as "page=2" will change when new posts are being added. #GNUSocial uses here something like "lastPostId" which is the id number of the last post that has been loaded and so displayed.

Maybe I better make an example on how I think how it can be done:

1) Load page and embed "last post id" directly into page
2) Send request out: "POST /ajax/network/?lastPostId=12345&page=current"
3) This returns the posts (lastPostId - postsPerPage) that just be displayed right away including a new lastPostId
4) The user scrolls up, send another request out: "POST /ajax/network/?lastPostId=12335&page=up" (I assumed 10 posts per page and again a new lastPostId is included)
5) On any of those requests, check that more can be loaded, if not, the new lastPostId should be empty, indicating that no more can beloaded
6) Similar when the user scrolls down, then &page=down is given

Maybe not perfect but newly added posts can be found out the same way:
"POST /ajax/network/?lastPostId=12345&page=up (as newer posts are added on top)

The JavaScript then needs to handle empty lastPostId (when < postsPerPage has been found) and removing/adding content.

Fritz!Fon C4 stays white or flickers

I have here a Fritz!Fon C4 (a softphone) with updated firmware. If I know insert batteries, the screen sometimes turn white or flickers but the phone seems to start and connect but remains unusable.

Any ideas besides removing battery and re-inserting it? I already filled a ticker with #AVM.
#AVM avm bug c4 problem softphone
So far not much progress. Also their suggestions on how to fix it did not work, the display remain ~99.9% white and only one time after a reset, I saw the blue start screen which became mixed up again after some seconds.

So I decided to wrote a complain to them.

poller.php multiple launched, eating up CPU

I wonder if the poller is really needed or if somehow the cron jobs can be executed without it? I had setup as it should be:

*/10 * * * * cd ${HOME}/friendica/htdocs/ && /usr/bin/php include/poller.php


If I let it runs, multiple php processes are forked eating up my CPU and slowing down the server. Currently it seems to work without it (and much faster).
#cron bug fadmin friendica poller
Maybe yours is better as it forks lesser processes. It was dirty hacking anyway. :)
It now seems to crash with "Terminated":

> cron_poller.sh: line 15: 32661 Terminated nice --adjustment=19 php ./include/poller.php

Zeile 15 ist genau der Befehl der hinter "Terminated" (TERM) steht.

The class does not have a descriptor, or a descriptor that does not use inheritance or uses a ClassExtractor for inheritance

The mentioned message still comes when you have @Inheritance (strategy = InheritanceType.TABLE_PER_CLASS) in your abstract (not-persisted) with latest version of #Payara / #Glassfish which both contains #EclipseLink by default.

Strange that they did not yet fix it. And unfortunally migrating to e.g. #WilfFly (which uses other #JPA) seems not so easy as you may think.

Currently I have no idea how to fix it and sadly I need the strategy as this #JavaEE application is written for an existing database layout.

Someone may have to raise a support ticket mentioning that the #bug is still there.

Reposted with #public visibility. Sorry for double message.

Nothing new here so far. Only they asked me to write a test-case for them ... :-(

My previous #JavaEE trainer said it is a bug in #Glassfish / #Payara but it starts to become more anoying. Does someone know something to prevent this from happening?

Yes, filling out a bug report may help. :-) But maybe there is a trick or so?

The most "outter" exception says:
javax.servlet.ServletException: javax.faces.view.facelets.FaceletException: javax.naming.NamingException: Lookup failed for 'java:global/jreports-ejb/contact!org.mxchange.jcontacts.contact.ContactSessionBeanRemote' in SerialContext[myEnv={java.naming.factory.initial=com.sun.enterprise.naming.impl.SerialInitContextFactory, java.naming.factory.state=com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl, java.naming.factory.url.pkgs=com.sun.enterprise.naming} [Root exception is javax.naming.NamingException: ejb ref resolution error for remote business interfaceorg.mxchange.jcontacts.contact.ContactSessionBeanRemote [Root exception is java.lang.ClassCastException]]


The interface in question (see the JNDI string end) "ContactSessionBeanRemote" is annotated with @Remote (javax.ejb.Remote) and not java.rmi.Remote as the exception says.

It is declared as following:
public interface ContactSessionBeanRemote extends Serializable {
...
}

Local "connect" not working

I think I found a #bug in #friendica, latest develop code. I have rebased my branch to latest changes and revert all of my is_filled_array() changes to dba::is_result().

So what I did was I created an account for my wife and tried to connect to but all I got was a redirect and no entry in table 'intro'. There is also no entry of her account in 'fcontact'.

So what is wrong?
#bug #friendica bug develop friendica
Ah, validate_url() misses to check $h with is_array(). Please try to cherry-pick my latest commits in branch rhaeder-develop (changed develop branch).
