1.2.3 (Sept 2023)¶
$PVXS_ENABLE_IPV6environment variable. Set
PVXS_ENABLE_IPV6=NOto disable usage of IPv6.
- IOC: A warning is printed if a group definition includes no
This is likely a mis-configuration by omission which will produce more monitor updates than expected.
- IOC: A warning is printed if a group definition includes no
pvxs::server::ConnectOp::error()no longer blocks.
IOC: fill in
Add Understanding Groups section.
Clarify some exception messages.
1.2.2 (June 2023)¶

operator =) add
Arrayw/ implied alloc+convert
client: fix batch pop() of exception
fix monitor pipeline and
server: add MonitorStat::nSquash
Add feature preview of QSRV 2 IOC server functionality.
1.1.4 (April 2023)¶
client: fix delta sync of Compound. Regression in 1.1.0.
Add wrappers for some libevent socket manipulations as Expert APIs.
Improve diff output of
msvc build compat.
/wd*compiler flags sometimes interpreted as paths.
1.1.3 (Mar 2023)¶
pvxs::Value::nmembers()which erroneously returned
Change to “magic” automatic
Unionmember selection during assignment.
Fix TypeDef(const Value& val) for Union/UnionA/StructA
Fix unsigned handling
server: rework cleanup of connection, channel, and operation
1.1.2 (Feb 2023)¶
1.1.1 (Dec 2022)¶
Fix protocol decoding error with TypeStore.
1.1.0 (Nov 2022)¶
Client Subscription yields “complete” Value to user code. Unchanged fields will appear with the values most recently received, kept in an internal cache. As a consequence, array and union fields will always be shared with this case, and can never be safety modified.
Change Server monitor watermark meaning from edge to level trigger.
pvxs::SigIntexecutes callback on worker thread instead of signal context.
1.0.1 (Oct 2022)¶
Fix c++17 compilation issue
Allow TypeDef to append StructA and UnionA
Reduce “non-existent IOID” noise
Fix CMD_MESSAGE handling
Fix locking of client monitor during pop()
Calculate buffer sizes in terms of OS socket buffer limit
Fix low water mark calculation
Fix Timer ownership (expert API)
assert()when client asked to search for PV names longer than 1400 bytes.
1.0.0 (Sept 2022)¶
Add hold-off timer when reconnecting to a specific server.
Fix missing closing quote when printing a
Stringin tree format.
0.3.1 (June 2022)¶
Fix ifaddrs::ifa_addr can be NULL
Limit beacon tracking by size as well as time
0.3.0 (May 2022)¶
Fix protocol incompatibility with Big Endian servers.
Add support for IPv4 multicast and IPv6 uni/multicast for UDP. And IPv6 unicast for TCP. See Address Spec. for entries which may now appear in EPICS_PVA*_ADDR_LIST.
PVXS now attempts to fanout unicast searches through the loopback interface, and to handle
CMD_ORIGIN_TAGmessages (aka. the local multicast hack).
pvxs::client::Context::discover()to enumerate and track PVA Servers.
pvxlistadd “continous” mode. (eg.
pvxlist -v -w 0) To immediately Discover new servers, then continue listening for Beacons to detect as server go up and down (like
casw). Also, to be gentler on your network, add
-Pto skip initial Discovery ping, and only listen for Beacons.
0.2.2 (Jan 2022)¶
No functional change to libraries.
Updates to python packaging.
0.2.1 (Oct 2021)¶
pvxsmonitorhang when interrupted (Ctrl+c).
pvxs::client::Subscription::shared_from_this()leaking internal reference.
Fix SharedPV potential race conditions involving “current” Value.
Ignore beacons with protocol field other than “tcp”. Forward compatibility.
Limit packet hex dumps to 64 bytes.
testStrMatch()now specified POSIX regular expression syntax.
Client operations builders
rawRequest(Value())is now a no-op. Previously produced a non-nonsensical empty request.
0.2.0 (July 2021)¶
Resolve ambiguity between Value::as(T&) and Value::as(FN&&) causing issue with GCC 4.8.
Fix encoding of (Sub)Struct w/ valid set.
Fix locking issue with client tracking of server beacons.
Fix binding to specific interface addresses.
To simplify usage in situations with complex threading, many client methods avoid unnecessary synchronization with the client worker thread. Cancellation still synchronizes by default, but this may now be controlled with the new syncCancel() Builder methods. cf.
Client Op Builder server() method now implemented.
Client channel cache now periodically prunes unused Channels automatically.
Add server ignore address list. cf.
pvxs::server::Config::ignoreAddrs. Configured from $EPICS_PVAS_IGNORE_ADDR_LIST.
Allow TCP timeout to be configured.
pvxs::client::Context::connect()to force Channel creation and retention.
Semi-public Expert APIs.
Update bundled libevent
Preliminary support for RTEMS 5.1 with libbsd
0.1.5 (May 2021)¶
Default logger level changed from Err to Warn.
Server warns when falling back from requested TCP port.
Public headers include <iosfwd> instead of <ostream>.
0.1.4 (APR 2021)¶
Fix potential locking issue monitor queue
Fix potential locking issue in Shared PV with concurrent open()/close() vs. post()
0.1.3 (FEB 2021)¶
Fix regression from 0.1.2 causing possible crash on targets defining SO_RXQ_OVFL (eg. Linux).
0.1.2 (FEB 2021)¶
Fix TCP connection “stall” (incorrect deferred read).
Raise UDP search reply processing limit.
Try not to fragment UDP search packets.
mailbox example can serve more than one PV.
Indent printed field=value in delta output mode.
0.1.1 (Jan 2021)¶
Fix decoding of “null” string. Addresses interoperability with pvAccessJava.
Increase inactivity timeout for TCP connections from 30 to 40 seconds. Also for interoperability with pvAccessJava.
Client search requests incorrectly set Server direction bit. (existing servers don’t enforce this)
Improved handling of errors resulting from pvRequest processing. eg. field selection which doesn’t select any fields.
PVXS_ABI_VERSIONet al. to pvxs/version.h
Changed name of automatic Sources
"__server". Document that Source names beginning with
0.1.0 (Dec 2020)¶
