processone/xmpp

This system is an Erlang/Elixir library for handling the XMPP protocol, providing core infrastructure for building and parsing XMPP stanzas and addresses. It implements support for various XMPP extensions (XEPs), including CAPTCHA forms, HTTP file uploads, and pubsub metadata, while offering utilities for validating URIs, language tags, and JIDs. The library relies on C-based NIFs for performance-critical parsing tasks and is licensed under Apache 2.0.

New C source files introduce Erlang NIFs that expose three capabilities: \xmpp\_uri:is\_valid/1\ validates strings against the RFC 7622 XMPP URI syntax, \xmpp\_lang:is\_valid/1\ validates language tags (including a workaround for Cisco Jabber's 'UTF-8' encoding suffix), and \jid:string\_to\_usr/1\ parses a JID string into its node, domain, and resource components.

The library now includes generated encoders and decoders for CAPTCHA data forms (XEP-0158) and HTTP File Upload data forms (XEP-0363). This enables applications to correctly parse and construct the specific data forms required for CAPTCHA challenges and file upload negotiations, ensuring compatibility with servers implementing these standards.

This release adds support for numerous XMPP extensions (XEPs) including CAPTCHA forms (XEP-0158), HTTP File Upload (XEP-0363), PubSub metadata, push notification summaries (XEP-0357), and SASL SCRAM with multiple hash functions. It also introduces new namespaces for MUC stable IDs, MAM 2, Full Text Search, Inbox, JID Prep, Chat Markers, Message Moderation, and various MIX and PubSub features. The \xmpp.hrl\ header now includes macros for stanza type, from, and to, and switches to \include\_lib\ for fast\_xml. Additionally, the project has updated its licensing from GPL to Apache 2.0 and refreshed copyright years.

include · high confidence

The repository is initialized with standard project metadata and build infrastructure. This includes a .gitignore file to exclude build artifacts and generated code, a CHANGELOG.md documenting the history up to version 1.13.5, and a README.md providing usage instructions for the Erlang/Elixir XMPP library. The build system is configured via a Makefile and rebar.config.script to support both rebar2 and rebar3, handling dependency resolution and compilation of C-based NIFs. Additionally, legal and community files (LICENSE.txt, CODE\_OF\_CONDUCT.md, CONTRIBUTING.md) and an Autoconf configure script are added to establish the project's licensing and contribution guidelines.

The asn1 module now includes the XmppAddr.asn1 file, which defines the ASN.1 structure for the XMPP address type (id-on-xmppAddr) as an OID under the PKIX mechanisms, allowing the system to properly encode and decode XMPP addresses in protocol streams.

The specs directory now includes new configuration and XData form definitions for XEP-0158 (CAPTCHA), XEP-0363 (HTTP File Upload), XEP-0357 (Push Notifications summary), and PubSub metadata fields. These additions provide the structural definitions required to parse and validate these specific XMPP data forms.
