Dear all,
We are glad to announce the final release of NaviServer 5.0.0, marking
the most significant update in the project’s history with over 70,000
lines of changes. This release delivers robust security enhancements,
modernized infrastructure, and improved scalability. Key highlights
include:
Security by Default: HTTP client requests now validate server
certificates automatically, with configurable trust exceptions and a
bundled CA root store. A new pluggable authorization framework (ns_auth)
enables scriptable request- and user-level access control.
Modernized Core: Unix domain socket support, case-insensitive
ns_set, Argon2 password hashing, and streamlined configuration via
environment variables (ideal for containers). The reverse proxy is now
built into the core, with new forward proxy capabilities.
Enhanced Observability and Scalability: Improved logging (dynamic
paths, rotation, and new "Security" severity), detailed connection
diagnostics (ns_conn urldict, ns_connchan debug), runtime introspection
(ns_http keepalives, ns_info buildinfo), persistent client connections,
and streaming HTTP client processing.
Backward Compatibility & Future-Readiness
While introducing cutting-edge features, NaviServer 5.0.0 maintains
strong backward compatibility, with deprecated APIs clearly documented
and modern replacements provided (e.g., ns_urlencode →
ns_percentencode). The release introduces/extends over 50 Tcl commands
and subcommands. The upgrade to MPL 1.2 and Tcl 9 support ensures
long-term sustainability. Over 20 community-contributed modules (like
nsdbpg, nssmtpd) have been updated in lockstep.
The following people contributed to this release:
Alexander Danilov, Andrew Piskorski, Antonio Pisano, Brendan Graves,
Brian Fenton, Danilo Raynor, David F, David Osborne, Filip Minic, Georg
Lehner, Gustaf Neumann, Hector Romojaro, Joe Oldak, Oleg Oleinick,

New Features:
-------------
Security Enhancements
• Security by Default when NaviServer is used as an HTTP client
(ns_http and ns_connchan)
All HTTP client requests now validate the peer server certificate by
default.
◦ Introduced the -insecure flag to bypass validation in trusted
scenarios.
◦ Bundled a ca-bundle.crt with well-known root certificates for
out-of-the-box verification support.
◦ Fine-Grained Validation Management:
▪ Configure validation exceptions in the httpclient section to
allow specific
certificate issues (e.g., self-signed certs) for defined IP
ranges.
▪ Define a directory for storing rejected certificates, enabling
later review,
manual trust decisions, or audit trails.
▪ For details, consult the admin-config manual.
• Certificate Management
Added new commands:
◦ ns_certctl list – List loaded certificates.
◦ ns_certctl reload – Reload certificates at runtime.
• Pluggable Authorization Framework
◦ Introduced flexible, scriptable request- and user-level
authorization:
◦ Supports multiple authorization handlers ("authorities") with
ordered evaluation.
◦ Handlers can return continuation codes (TCL_OK, TCL_BREAK,
TCL_RETURN)
to control the authorization chain.
◦ New Tcl commands:
▪ ns_auth request – Evaluate configured request-level auth
handlers.
▪ ns_auth user – Evaluate user-level authorization logic.
• Improved Reverse Proxy Trust Management
◦ Define trusted upstream proxies via CIDR ranges.
◦ Configurable handling of X-Forwarded-For chains, including:
▪ Skipping non-routable addresses.
▪ Alternative resolution strategies.
◦ Improves accuracy and security of client IP logging (e.g., in
access.log).
◦ For implementation details, see commit ab23158ece.
• Argon2 Password Hashing New command: ns_crypto::argon2
Provides support for modern, secure password hashing.
User Interface and HTML Improvements
• Modernized Default Start Page
◦ Redesigned layout with responsive and accessible design.
◦ Added modal dialog for password updates.
◦ Improved security guidance for publicly exposed installations.
◦ Installer now fetches resources from GitHub (previously
Bitbucket).
• Dark Mode Support
◦ Automatically respects system preferences via the
prefers-color-scheme media query.
◦ Supported across modern versions of Windows, macOS, iOS, and
Android.
• Consistent Visual Styling
◦ Unified look and feel across:
▪ Default start page
▪ NaviServer documentation
▪ nsstats module interface
Configuration and File Management
• Configuration via environment variables
◦ Added ability to pull in environment variables with a certain
prefix as
configuration variables for configuration files (new command
ns_configure_variables). This helps configuration significantly
for
container-based deployments, where ports etc. have to be adjusted
on
standardized configuration files.
• New File Location Options
◦ Unified log path resolution via logdir or serverdir.
◦ Moved serverdir definition from fastpath to the top-level server
section;
it now acts as the root for both logdir and page directories.
◦ Added bindir parameter for custom binary module and nsproxy worker
locations.
• Improved Log Configuration
◦ Relative log file paths are now resolved consistently based on:
▪ serverrootproc (for mass virtual hosting), or
▪ serverdir.
◦ Supports dynamic log file naming (e.g., using Host header) for
per-vhost logging.
◦ Log rotation now applies across multiple log targets.
• Improved Section Parameter Updates
◦ New -update flag for ns_section, allowing ns_param to overwrite
previously
defined values rather than appending.
Proxy Features
• Reverse Proxy Integration
◦ The reverse proxy module is now built into the NaviServer core.
◦ Leverages improvements in ns_http, including:
▪ Persistent connections
▪ Streaming request handling
◦ New features:
▪ -use_target_host_header flag for ::revproxy::upstream to control
Host header forwarding.
▪ Configurable transport mechanism using either ns_http or
ns_connchan.
▪ Support for backend connections via Unix domain sockets.
• Forward Proxy Implementation
◦ Base implementation included, built on the same scalable
architecture as the reverse proxy.
◦ Full support for the HTTP CONNECT method:
▪ Enables tunneling HTTPS connections through the proxy.
▪ Eliminates the need for insecure plaintext fallbacks.
Additional Functional Improvements
• Case Insensitive ns_sets
◦ Optionally define ns_set to be case insensitive.
Many usages are per definition case insensitive (header fields,
configuration values, SQL attribute names, ...).
Has correctness and performance impacts.
• Unix Domain Socket Support
◦ Both ns_http and ns_connchan now support connections via Unix
domain sockets.
• Multibyte HTML Entity Support
◦ ns_striphtml and ns_unquotehtml now correctly decode multibyte
numeric HTML entities.
• New Log Severities
◦ Security – For security-related events.
◦ Deprecated – For usage of deprecated features (e.g., API calls,
parameters).
• TclPro Debugger Support
◦ Significantly improved integration with the TclPro debugger.
◦ Resolved missing file references and corrected documentation.
◦ See the ns_adp_debug manual for usage.
• Tcl 9 Compatibility
◦ Internal updates to support Tcl 9 features and constraints.
◦ Support for Tcl command argument counts >2^31.
• License Upgrade
◦ Changed from MPL 1.1 + GPL to MPL 1.2.
◦ Announced previously on the mailing list and Tcl forums.

Bug Fixes
Stability and Crash Resolutions
• Addressed multiple potential crash scenarios:
◦ Robust handling of HTTP CONNECT requests.
◦ Fixed crashes caused by missing or empty argument lists in
commands such as ns_filestat,
ns_sockcallback, and ns_ictl oncleanup.
◦ Prevented crash in ns_log when invoked with an empty message.
◦ Resolved a 24-year-old bug in Ns_AdjTime() that could lead to
fatal errors due to
microsecond overflow in multithreaded environments.

overlapping regions
(notably on aarch64 with musl).
◦ Resolved crash in Ns_SetIUpdateSz() caused by case mismatch in
header keys with the legacy C API.
◦ Fixed crash during nscp startup when the users section was not
configured.
◦ Prevented crash in debug mode when the Host: header could not be
mapped to a virtual server
and the driver was installed locally.
◦ Avoided crash when launching nsd with -c and -t options and no
home parameter defined.
◦ Fixed crash during computation of ns_conn location when the
network driver was not
globally installed (global installation now recommended).
◦ Fixed crash due to self-destructive header replacement when
ns_conn outputheaders
are passed via ns_respond ... -headers ...
Functional Correctness and Logic Fixes:
• ns_conn status: Fixed issue where updated status codes were silently
ignored.
• ns_conn doneCallback: Ensured this callback is always invoked in
ns_http.
• nsv_dict get: Fixed a memory leak in value retrieval.
• ns_conn peeraddr: Resolved race condition in pipelined requests that
could yield incorrect peer addresses.
• ns_cache_eval -force: Fixed race condition that could produce
obsolete results.
• ns_sema create: Corrected handling of initial count values (e.g.,
1000).
• ns_trim: Fixed spacing logic to trim only leading and trailing
whitespace, preserving internal spacing.
• ns_config -int: Corrected fallback behavior when invalid values are
supplied,
now correctly using documented defaults.
• ns_sockcallback: Now gracefully handles missing arguments.

trimming.
• Fixed ns_conn location when running behind a reverse proxy to always
returns a value,
even in broken configurations.
OpenSSL fixes
• Added support for detecting and validating OCSP Must-Staple and AIA
presence
in certificates. Without that, NaviServer might crash, when OCSP is
turned on,
and NULL values are passed for AIA URLs (letsencrypt)
• Introduced stable output buffers for send operations to support
retries
after SSL_ERROR_WANT_WRITE, preventing connection failures under
high load.
• Improved error handling in OpenSSL integration by draining the error
stack via DrainErrorStack().
HTTP Client Fixes
• ns_http:

can access a fully configured server state.
HTML and ADP Parsing Fixes
• ADP Parser:
◦ Enhanced support for quoted > characters inside attribute values,
aligning with modern HTML parsing rules.
• return-notice handling:
◦ Suppressed spurious error messages when fallback ADP templates are
processed outside of a full ADP context.

incorrectly decoded;
only the first entity was processed.
Logging and Diagnostics Fixes
• Fixed misleading log output when dynamically changing extended
headers via
ns_accesslog extendedheaders ....
• Improved error messages when port binding fails due to conflicts
with driver assignment.
• Fixed off-by-one error in the virtual server port configuration
logic.
• Clarified or corrected multiple logging messages across modules for
better diagnostics.
nscgi Module Fixes
• Fixed file upload failures when uploads were internally spooled by
NaviServer —
previously returned 500 errors.
• Corrected processing of CGI script exit codes not 0.
• Fixed hostname and port reporting for SERVER_NAME.
Database Fixes
• ns_db rowcount: Fixed regression where the row count logic was not
invoked, rendering the command a no-op.
Build and Compatibility Fixes
• Suppressed obsolete --enable-threads warning for Tcl versions where
thread support is now enabled by default.
• Fixed compilation failure with glibc 2.38+ due to PTHREAD_STACK_MIN
becoming dynamic via sysconf().
General Cleanups
