Updated Version of the apache http caching setup for snac, including proxy media
I already wrote about caching here
Now I extended what I cache a bit.
This was because after enabling Option to proxy media I've seen access to the file paths /x/ and /y/ in addition to the path were snac stores the media that I include in my own posts ( /s/ ).
There are two locations to proxy media, depending if you requests the media via the mastodonapi or via the web. (/x/ and /y/), oh and I added the nodeinfo2 path too, because I've noticed it was queried all the time by a lot of instances and it gives me pleasure to see something cached handed out in the access logs 🙂 (I guess it is actaully irrelevant for the system resources).
This is the updated setup:
Enable the relevant modules:
a2enmod expires cache cache_disk
Be sure "htcacheclean" is running to clean up old disk cache. (under debian see /etc/default/apache-htcacheclean or else the relevant systemd service or whatever)
Then add to the snac Virtualhost config:
<LocationMatch "^/social/[^/]+/[xys]/|^/social/nodeinfo_2_0">
CacheEnable disk
Header set Cache-Control "max-age=86400, public" "expr=%{REQUEST_STATUS} == 200"
ExpiresActive On
ExpiresDefault "access plus 86400 seconds"
</LocationMatch>
This will use the disk cache to cache everything under the /s/, /x/ and /y/ Path, as well as for /$username/nodeinfo20, utilizing the mod_expires to generate the appropriate cache headers (for lazy ones like me), In this case caching it for 1 day.
Further reading and all options explained under https://httpd.apache.org/docs/2.4/caching.html (and ff)
The Header that I set here, on the condition of Status code 200, is needed for the path /y/, because snac defaults to set no-cache on that location and the modexpires will honor that if we don't override it. I set it to the same Cache-Control value as modexpores woud. (mod_expires will additionally calculate the date and put that in the expiresheader. (hence the name I guess 😀 )

#snac / activitypub noob #question:
job fifo size (cur): 655
job fifo size (peak): 1291
thread #0 state: waiting
thread #1 state: output
thread #2 state: output
thread #3 state: output
This number is decreasing over some minutes after I made a post,
I assume it is my instance delivering this to all subscribers, is that correct?
And the last thread will stay idle to maybe wait for incoming requests, so that they can be answered too?
I've never seen another status then waiting or output so far.
I guess if I post a picture that might then happen and all workers will be busy? Maybe even too busy to keep up?
Is that assumption about how the waiting worker and what it is for correct?
If yes I guess I'll increase the threads, if they are intentional low for low ram systems, that's not my issue with snac. (I've not much ram, but I assume snac is by default tuned to be very very very conservative?)
(adding Pic to simultaneously test my theory)

Hi @nprofile…73zh, thanks for the answer. I tried it and it still doesn't work.
To be concrete: I follow Hashtag "Hannover" (don't want to really put # in front of it here now)
And I keep getting advertisement with that hashtag like for example: https://kollegin.eu/users/Ladies_DE/statuses/113985025811332629
But from multible accounts, so I thought I could block Hashtag "Ladies_DE"
I created /var/lib/snac2/filter_reject.txt with appropiate permissions and added:
(?i)[#@]Ladies_DE
#Ladies_DE
( first only the second line, but it wasn't working so I tried more, but I still get the advertizments from these accounts. They all have the hashtag, so should be discarded)
I don't know where I have to look, what to do to further debug this.

I'm using snac with and am following Hashtags now, and am getting a lot of nice content from specialized Hashtag-Relays. I have now a Problem with unwanted Posts that happen to use Hashtags I want to keep too. But I could Filter them my unwanted Hashtags they use.
Snac supports regex, but now The Question:
how do I know in what form the Regex is expected in my filter_reject.txt?
I want to block a Hashtag case insenitive
/#WhatIBlock/i
or (?i)#WhatIBlock
or maybe something else? It Seems the web is full of different ways to specify regex.

This is one of the intended properties, a similarity to cash.
But one shouldn't store a lot of cash at home as everyone knows 🙂.

Ich bin skeptisch ob das stimmt, oder ob nicht aktuell aus Panik auch mal sachem geteilt werde die jemand erfunden hat.
Mir wurde bei einer Schulung gesagt, man benötige sowohl die Karte des Heilberuflers, die des Patienten, und dann muss der sein Passwort eingeben.
Und hier steht jetzt jeder kann einfach das passwort nutzen, ohne das der a Kunde jemals seine Karte durchgezogen hat?

Ich befürchte dann haben wir verloren, weil das nicht zu ändern ist. Ich halte es für ausgeschlossen, daß eine Konkurrenz bei Preis und Geschwindigkeit möglich ist.
Dafür hat Amazon zuviel Geld und Erpressungsprotential, bei ihren Marketplace "Kunden" (den Unternehmen) sodass sie Bereiche wie den Transport massiv subventionieren können.
Ich denke auch, dass das politisch geändert werden muss und das Verhalten des einzelnen nicht ausreicht.
Aber ich gebe nicht kleineneren Unternehmen die Schuld das es so ist wie es ist.

Ich finde auch, bei Lieferzeit und Angebotsumfang ist Amazon konkurrenzlos.
Wo anders muss man teils mehr zahlen, es dauert länger, und man muss mehr Shops durchsuchen.
Aber wenn dass der Preis ist, das man nicht selber die Dystopie stärkt, dann ist das gut angelegte Zeit und Geld.

Damit unified push was bringt, braucht sowohl die App die den push bekommen soll, als auch ihre Server Seite unified_push Support.
Wenn die App nur Google push kann, dann braucht man Google push. Und dafür ist Microg da.
Für unified push nimmt man einen unified_push Distributor wie nextcloud, ntfy, Conversations....
