2.2.2 – 2022-11-07
Fix handling of (invalid) facility values higher than 31.
- Use
PSTR_ALIGN
for flash strings.
- Facility values higher than 31 (values higher than 23 are not allowed by the
uuid::log::Facility
enum) would cause the priority value to be out of range (more than 3 digits).
2.2.1 – 2022-10-29
Fix thread-safe mode and mark message handling.
- Limit the maximum number of log messages that can be transmitted in one loop iteration.
- Crash when transmitting messages when operating in thread-safe mode.
- Last message time wasn't being updated so a flood of mark messages would occur when the uptime reached the mark interval.
2.2.0 – 2022-10-26
Be thread-safe (for log messages) where possible.
- Indicate whether this version of the library is thread-safe or not (
UUID_SYSLOG_THREAD_SAFE
anduuid::syslog::thread_safe
).
- Make the library thread-safe (for log messages only) when supported by the platform.
2.1.2 – 2022-02-28
Fix performance on the ESP32.
- Include lwIP headers directly so that messages can be sent faster on the ESP32.
2.1.1 – 2022-02-23
Silence irrelevant compiler warnings when building on the ESP32.
- Silence compiler warnings/errors about
%S
in a format string.
2.1.0 – 2022-01-27
More visibility of the log message queue and control over the rate at which messages are dispatched.
- Function to get the current size of the log message queue.
Symbols to control the UDP message sending delay:
UUID_SYSLOG_UDP_BASE_MESSAGE_DELAY
UUID_SYSLOG_UDP_IPV4_ARP_MESSAGE_DELAY
UUID_SYSLOG_UDP_IPV6_NDP_MESSAGE_DELAY
It is inadvisable to change these because UDP packets may be queued and then discarded by the platform when the queue limit is reached.
- Relax IPv6 scope checking when waiting for a local address to allow either global or local unicast addresses to be used with any global or local unicast destination. Previously they had to be the same type.
2.0.6 – 2021-04-18
Upgrade to PlatformIO 5.
- Use PlatformIO 5 dependency specification.
2.0.5 – 2021-01-17
Upgrade to the latest version of the logging library for static initialization and deinitialization fixes.
- Don't unregister handler explicitly in the destructor, this is now handled by the logging library.
2.0.4 – 2019-09-22
Fix log message transmit retries.
- Log messages that failed to be sent are not left on the queue correctly and may cause a crash when they are retried.
- Add memory barrier around checks for log queue overflow.
2.0.3 – 2019-09-21
Feature detection fixes.
- Use
gettimeofday()
on the ESP32. - Don't redefine
UUID_SYSLOG_ARP_CHECK
.
2.0.2 – 2019-09-20
Support IPv6 addresses.
- Use move constructors on rvalues.
- Support for IPv6 addresses.
2.0.1 – 2019-09-05
Bug fix for trace level messages.
- Use debug level for trace level messages.
2.0.0 – 2019-09-03
Additional features and API changes.
- Functions to get all of the configuration parameters.
- Support for sending a
-- MARK --
message when there is no activity for a configurable period of time.
- Add log level to the message text.
- Lower the log level of log level change messages to
INFO
. - Rename
set_host()
todestination()
. - Remove
get_
andset_
from function names.
- Function to set the maximum number of log messages is no longer limited to 0 or 1.
1.0.0 – 2019-09-01
First stable release.
- Buffer messages during startup until configuration is provided.
- Automatic use of system time if it is available.
- Wait for the network to be available before transmitting.
- Explicit ARP check for the destination host on ESP8266 and ESP32.
- Rate limiting of output packets to avoid dropped messages.
- Configurable destination host and log level.
- Configurable local hostname.
- Configurable queue size.
