Angie Version History#

2024#

Angie 1.7.0#

Release date: 19.09.2024.

Features#

  • Forced closing of all connections to a proxied server when it's removed from the group can be configured via the proxy_connection_drop, grpc_connection_drop, fastcgi_connection_drop, scgi_connection_drop, and uwsgi_connection_drop directives.

  • Counters of sent DNS query types in the resolver statistics API, which is collected with the status_zone parameter of the resolver directive.

  • The $ssl_server_cert_type variable that contains the type of selected certificate for a received TLS-connection.

  • Disabling creation of the PID file with the off parameter of the pid directive, which might be beneficial with immutable images and direct control by a service manager. Thanks to Maxim Dounin (freenginx).

  • Creation of the PID file made atomic via an intermediate temporary file, which removes a moment when the file is already in the directory but still empty, and allows external programs to handle it more easily and reliably.

  • Now, during reconfiguration, no attempt is made to recreate the PID file if the name in the pid directive has changed but points to the same file via symlinks; in particular, it allows avoiding issues on systems that migrate from /var/run/angie.pid to /run/angie.pid. Thanks to Maxim Dounin (freenginx).

  • Syslog logging errors are now reported no more than once per second; this helps avoid flooding the logs with such messages when the syslog server is down or overloaded. Thanks to Maxim Dounin (freenginx).

  • In the Mail proxy module, the maximum number of commands during authentication, configured with the max_commands directive, is limited to better protect against DoS attacks. Thanks to Maxim Dounin (freenginx).

  • The --feature-cache option of the ./configure script to cache its results for optimization when building multiple modules or cross-compiling.

  • All functionality of nginx 1.27.1.

Bugfixes#

  • PID file ... not readable (yet?) after start and Failed to parse PID from file... errors might appear when starting with systemd. Thanks to Maxim Dounin (freenginx).

Changes#

  • Updated descriptions of HTTP status codes in conformance with RFC 9110. Thanks to Maxim Dounin (freenginx) and Michiel W. Beijen.

  • A maximum of one empty line is now allowed before an HTTP request to better protect against DoS attacks. Thanks to Maxim Dounin (freenginx).

  • HTTP/1.x header field names without a colon at the end are now prohibited; such invalid header fields from a client or a proxied server will now cause an error response. Thanks to Maxim Dounin (freenginx) and Maksim Yevmenkin.

  • When reading a request body using HTTP/1.1 chunked transfer encoding, the total size of ignored chunk extensions and trailer header fields is now limited by the client_max_body_size directive to better protect against DoS attacks. Thanks to Maxim Dounin (freenginx) and Bartek Nowotarski.

  • The MIME type in the mime.types configuration file has been changed to image/bmp for the bmp extension and application/vnd.rar for the rar extension; set to application/vnd.debian.binary-package for the deb and udeb extensions. Thanks to Yuriy Izorkin.

Packages#

Angie 1.5.1#

Release date: 16.05.2024.

Bugfixes#

  • The proxy_next_upstream mechanism did not work correctly when using the resolve option of the server directive in the HTTP block if the number of resolved IP addresses differed from the number of specified servers.

  • While requesting a certificate via the ACME protocol, a segmentation fault could occur in a worker process.

  • The slow_start mechanism did not work when proxying TCP connections in the stream module.

  • HTTP/3 requests could result in an error if received as TLS 1.3 early data; the bug had appeared in 1.4.0.

  • HTTP/3 connection could be prematurely closed while using 0-RTT in QUIC.

  • When reading a request body from a fast connection, reading for a long time was possible. Thanks to Maxim Dounin (freenginx).

Changes#

  • Output statistics metrics with dates in Epoch format instead of ISO 8601 for use in Prometheus and optionally in the JSON API with the ?date-epoch request argument.

  • New recovering state for upstream peers in the statistics API, indicating that a peer is slowly starting up after a failure, as suggested by the slow_start option.

  • Now the -V switch also shows the relevant version of nginx, which is useful for compatibility with third-party utilities, certbot in particular. Thanks to AdvTechnoKing.

  • All functionality of nginx 1.25.4.

Bugfixes#

  • If the SSL session reuse mechanism proxy_ssl_session_reuse was used and the list of proxied servers was dynamically updated, a leak could occur in the shared memory zone configured for the corresponding upstream block.

Packages#

2023#

Angie 1.4.0#

Release date: 12.12.2023.

Features#

  • Support for establishing HTTP/3 connections to upstream servers in the HTTP proxy module while allowing clients to use arbitrary HTTP versions. Configuration is done with the proxy_http_version directive and a set of proxy_quic_ and proxy_http3_ directives.
