Piwik 2.1 — Massive Performance and Reliability Improvements
4 mars 2014, par Benaka M. — Community, DevelopmentWe are very excited to announce the immediate availability of Piwik v2.1.0 !
- Download Link
- How to update Piwik ?
- List of all tickets closed : Changelog
Piwik 2.1 is the first release after our 2.0 release and it reflects the new direction Piwik is moving in : better performance, more reliability and a better overall open platform ! We also released more plugins on the marketplace as well as helped developers build exciting new plugins for Piwik.
This 2.1.0 release contains several performance and reliability improvements to the archiving process and to the new device detection process introduced in Piwik 2.0. It also includes a new email report format (CSV), a new marketplace plugin and overall more than 80 improvements (source).
Massive Performance Improvements to Archiving
The biggest improvement this release brings to Piwik are the various performance improvements made to the Archiving Process. These improvements include the following :
- The amount of memory used has been reduced in some cases by 80% or more ! What used to require 8GB of memory will now only require 1GB. Piwik engineers analysed Profiler XHProf reports of Piwik under high load and implemented several improvements to archiving.
- The cron script you can setup to automatically process your reports will now create new processes to perform asynchronous archiving instead issuing CURL http requests. This change results in increases to the performance and reliability of the Archiving Process.
Bug Fixes and Performance Improvements to Device Detection
In Piwik 1.12 we introduced a new device detection feature that could detect much more information than what we used before. Piwik 2.1 includes several bug fixes and improvements to this feature (such as detecting dozens of new devices, brands and models for smartphones, tablets and other devices). To use this feature, go to “Settings” then “Plugins” then activate the DevicesDetection plugin.
New Default MySQL Database Type (InnoDB)
This change doesn’t affect our existing Piwik users, but it does reflect our commitment to performance and reliability. We’ve changed the default MySQL database type to be InnoDB instead of Myisam. This will allow new users to immediately gain the benefits in reliability offered by InnoDB.
New Marketplace Plugin – HTTP Authentication
We’re releasing a new plugin on the marketplace that will allow you to use the HTTP authentication services provided by your webserver. Learn more about this plugin on the marketplace.
New Email Format for Scheduled Reports
The last big change in this release is a new email report format. You can now get your email reports as CSV files as well as HTML and PDF reports.
Other Improvements
In addition to performance improvements and new plugins, this release contains a few other smaller improvements described below.
Changing segments in the Embedded Dashboard
The embedded dashboard is the powerful feature that lets you include the Piwik Dashboard without the top menu and Piwik branding, directly within your application !
This dashboard will now include the segment selector allowing you to change the current segment and create new segments, just as you would in the normal dashboard view :
Multiple Super Users
It’s now possible for your Piwik to have more than one Super User and for Super Users to have aliases :
Learn more in the User guide : Managing Super Users in Piwik.
Smart App Banners for our Mobile Apps
Finally, in accord with our commitment to providing great User Experience, we’ve added a smart banner to Piwik so users that view Piwik from a mobile device will be informed of our amazing (and free !) mobile apps (for both iOS and Android).
Participate in Piwik
Are you a talented developer or an experienced User Interface designer ? If you have some free time and if you want to contribute to one of the most awesome open source projects around, please get in touch with the Piwik team, or read this page to learn more ?
Summary

Thank you to the core developers, all the beta testers and users, our official supporters, the translators & everyone who reported bugs or feature requests. Also thank you to the software we use, and the libraries we use.

ffmpeg Command in Docker with Rust Tokio Closes Warp Server Connection (curl 52 Error)
3 juin 2024, par user762345I’m encountering an issue where executing an ffmpeg concatenation command through Rust’s Tokio process in a Docker container causes subsequent HTTP requests to fail. The error occurs exclusively after running the ffmpeg command and making immediate requests, resulting in a “curl 52 empty response from server” error with the connection being closed. Notably, this issue does not occur when running the same setup outside of Docker. Additionally, if no HTTP requests are made after the ffmpeg command, the curl 52 error does not occur.


Here is the verbose curl output of my minimum reproducible example (see below).


curl -v "http://localhost:3030"
* Trying 127.0.0.1:3030...
* Connected to localhost (127.0.0.1) port 3030 (#0)
> GET / HTTP/1.1
> Host: localhost:3030
> User-Agent: curl/8.1.2
> Accept: */*
> 
* Empty reply from server
* Closing connection 0
curl: (52) Empty reply from server


Here are Docker logs from my minimum reproducible example (see below). The wav files are concatenated successfully, then the container appears to rebuild.

What I have tried :
I tried using different web frameworks (Warp, Actix-web) and request crates (reqwest, ureq). I also tried running the setup outside of Docker, which worked as expected without any issues. Additionally, I tried running the setup in Docker without making any HTTP requests after the ffmpeg command, and the connection closed successfully without errors. I also tried posting to httpbin with a minimal request, but the issue persisted.


Minimum reproducible example :


main.rs


use warp::Filter;
use reqwest::Client;
use std::convert::Infallible;
use log::{info, error};
use env_logger;
use tokio::process::Command;

#[tokio::main]
async fn main() {
 std::env::set_var("RUST_LOG", "debug");
 env_logger::init();

 let route = warp::path::end()
 .and_then(handle_request);

 info!("Starting server on 0.0.0.0:3030");
 warp::serve(route)
 .run(([0, 0, 0, 0], 3030))
 .await;
}

async fn handle_request() -> Result<impl infallible="infallible"> {
 let client = Client::new();

 let output = Command::new("ffmpeg")
 .args(&[
 "y",
 "-i", "concat:/usr/src/minimal_docker_webserver_post_error/file1.wav|/usr/src/minimal_docker_webserver_post_error/file2.wav",
 "-c", "copy",
 "/usr/src/minimal_docker_webserver_post_error/combined.wav"
 ])
 .output()
 .await;

 match output {
 Ok(output) => {
 if output.status.success() {
 info!("WAV files concatenated successfully");
 } else {
 error!("Failed to concatenate WAV files: {:?}", output);
 return Ok(warp::reply::with_status("Failed to concatenate WAV files", warp::http::StatusCode::INTERNAL_SERVER_ERROR));
 }
 },
 Err(e) => {
 error!("Failed to execute ffmpeg: {:?}", e);
 return Ok(warp::reply::with_status("Failed to execute ffmpeg", warp::http::StatusCode::INTERNAL_SERVER_ERROR));
 }
 }

 // ISSUE: Connection closes with curl: (52) Empty reply from server
 match client.get("https://httpbin.org/get").send().await {
 Ok(response) => info!("GET request successful: {:?}", response),
 Err(e) => error!("GET request failed: {:?}", e),
 }

 match client.post("https://httpbin.org/post")
 .body("field1=value1&field2=value2")
 .send().await {
 Ok(response) => info!("POST request successful: {:?}", response),
 Err(e) => error!("POST request failed: {:?}", e),
 }

 Ok(warp::reply::with_status("Request handled", warp::http::StatusCode::OK))
}
</impl>

FFMPEG command to generate the two wav files for concatenation


ffmpeg -f lavfi -i "sine=frequency=1000:duration=5" file1.wav && ffmpeg -f lavfi -i "sine=frequency=500:duration=5" file2.wav
