Dear all,
on sourceforge is a release candidate for NaviServer 4.99.21 [1].
This is essentially a bug-fix release and cleans everything up, what was
reported after the larger release of 4.99.20 as an issue. The in-depth
look of the changes of oleg (as reported before the release of 4.99.20)
are still on our agenda.
I have tested the code with Ubuntu 20.04, macOS 10.14.6, FreeBSD-12.2,
OpenBSD 6.8.
The code is already running on openacs.org.
Below is a preliminary summary of changes. Please test if possible.
The release should be in about one week.

New Features:
-------------
- Logging improvements: Added parameter "logsec" and "logthread" for
section "ns/parameter" to make logging of full timestamps and
thread info optional. This give more control to a developer to
shorten the log entries e.g. on development instances by excluding
certain values.
- Made "ns_http ... -decompress ... "obsolete in favour of new option
"-raw". This fixes as well a crash.
Bug Fixes:
----------
- Fixed computation of "location" of a request for cases, where the
network driver is not installed globally. The value of [ns_conn
location] (and the redirect target) is often, but not always
determined by the host header field as used for virtual servers.
- Fixed handling of sendBodyLength in ns_http
- Fixed handling of user-ids in nscp.
- Fixed potential segmentation violation in debug output, when (a) the
network driver is installed locally, and (b) the content of host
header field cannot be located in virtual server map (fallback to
validation via driver data).
- Fixed potential segmentation violation when nsd is called with '-c'
and '-t' and the config file contains no "home" parameter in the
config file. The fix simplifies the logic, and performs same
configuration of nsconf.home whenever "-c" is used in the command
line.
- Increase sysadmin-friendliness of OCSP handling in error cases: In
case OCSP (Online Certificate Status Protocol) is activated and the
connection to the AIA-server is blocked, do not reject all traffic
but behave like in a configuration without having OCSP activated,
and complain the system log. Background: Sometimes requests to the
let's encrypt AIA server seems to be blocked by
firewalls. Previously, in such stituations, all traffic was
blocked.
- Relax bailing out on malloc(0), since at least the OpenSSL 3a*
versions use this frequently on certain configurations. Calls of
malloc(0) are essentially useless and dangerous, but we cannot
avoid these.
Performance improvements:
-------------------------
- Added support for TCP_NODELAY for https sockets via configuration
option "nodelay" in the nsssl driver section. For whatever reasons,
NaviServer handled so far this option. The option can reduce the
time of connection calls via https (clearly measurable in benchmark
setups).
Documentation improvements:
---------------------------
- improved the following man pages
doc/src/manual/admin-config.man
doc/src/manual/admin-tuning.man
doc/src/manual/main-history.man
doc/src/naviserver/ns_http.man
doc/src/naviserver/ns_http.man
doc/src/naviserver/ns_write.man
nsdb/doc/mann/ns_db.man
Configuration Changes:
----------------------
- New options "logsec" and "logthread" for section "ns/parameter"
(see above)
Code Changes:
-------------
- Extended regression test to cover e.g. the error cases from above.
- Code Cleanup
. Removed obsolete and deprecated functions ctime_r()
and asctime_r() in favor of strftime().
. Removed calls to deprecated Tcl functions
- Don't pass (implementation-defined) NULL as last argument of a
variadic function.
- Usual cleanup, such as reduced implicit type conversions,
removed uselass casts, removed dead assignments
- Improve comments, fixed typos
