R4.4.2: Update the env.slac.sh.in template to support the new buildroot version 2019.08. Add the buildroot-2016.11.1 targets to the list f ARCHES. rssi_bridge: remove infinite while loop from the CMover::threadBody(). R4.4.1: src/makefile: Adding cpsw_stdio.h into list of headers as it needed by cpsw_error.h. R4.4.0: config.mak: change default arches to buildroot-2019.08 cpsw_api_builder.h: Remove enum keyword when using a typedef-ed enum. This was failing with gcc-8.3.0 on builroot-2019.08 cpsw_preproc: use main yaml directory if yaml_dir is "" cpsw_yaml rework: provide more context in error messages; track unrecognized/unused YAML keys. Revamped cpsw_ypp. yaml_cpp python wrapper: added YAML::Node::size() Support loading YAML and building hierarchy without starting I/O. Added new 'startUp()' member function. Enhanced (auto-generated) 'git_version_string.h': - prefix all symbols as well as the header file name itself with a package prefix (cpsw/CPSW in our case). - define API version (= major version) in cpsw_api_user.h header. R4.3.1: pycpsw.stamp had not been updated R4.3.0: Support for a YAML_PATH env-var. This can list multiple directories where to look for YAML files. Useful, e.g., to locate files provided by user or globally which do not reside in FW directory. Added IEntry::dump() to python wrapper. Print useful info, (in particular about networking in case of the root node). R4.2.0: Changed default RSSI retransmission/cumulative-ack timeouts from 10/5ms to 100/50ms. Seems to mitigate problems when multiple RSSI connections share a network link/stack under heavy load. Made RSSI connection parameters (which are proposed to the server for negotiation) configurable (via YAML). Fixed RSSI reopen-delay. This was always reset to 0. FW does not like to be hammered with SYN requests -- it would just never respond. We work around this by backing off with an increasing delay. If FW is left alone for a while a reconnection succeeds. Ensure protocol module's modStartup()/modShutdown() are executed only once (the same module can be used by multiple communication ports). Added support for obtaining interface MTU in libTstAux; this is used by rssi_bridge to fragment larger messages. R4.1.2: Removed R4.1.1 tag which had been forced. build with boost 1.64.0 and yaml-cpp-0.5.3_boost-1.64.0 SequenceCommandImpl: a lot of existing YAML write '1' to a command in order to execute. Should really be '0' but was never checked by previous releases. With support for multiple sub-sequences the argument now has a meaning. For sake of backwards compatibility we accept any argument in case a sequence is 'one-dimensional'. SequenceCommandImpl: permit creation of a ScalVal_Base interface yaml_cpsw_merge (program): fixed -Y option R4.1.0: Use python 3.6.1 by default. SequenceCommand now supports two-dimensional sequences, i.e., a sequence of command sequences. This can be used to let the user pick a sequence at run-time. Handy in combination with an attached 'enum' menu. Note, this is accessible via the ScalVal_WO user API, not Command. Implemented new, more efficient handling of merge keys. R4.0.0: Feature: added cpsw_fs_address which implements access to the underlying file-system. (E.g., char-devices). Feature: may now create ScalVal_WO interfaces - but writes are marked as non-cacheable. Feature: cpsw_entry/cpsw_entry_adapt: promoted 'singleInterfaceOnly' feature from static- to virtual method. Individual entries can now reject creation of multiple interfaces. This feature is now settable from YAML. pycpsw BUGFIX: RuntimeError when IYamlFixup::findByName() didn't find a node SequenceCommand: now also recognizes 'system()' for executing native scripts, code etc. Internal read/write API rework. Merged 'swig/cython' branch. Major changes involve c++11 support and migration from boost::python to cython. All python wrappers have been migrated. This means that boost is no longer necessary (if c++11 is available). A few headers (lockfree) are still used but can be disabled in the configuration file (switch to a native but simple implementation which may or may not be less performant). API enhancement: added asynchronous 'getVal' + notification via callback. R3.branch: BUGFIX: cpsw_path findByName() crashed when ".." crossed root Created a R3.branch tag prior to merging major updates The python wrapper is generated with CYTHON by default. Boost is still supported (in case the new cython wrapper makes problems). Experimental support for SWIG is also available. Eventually, however, BOOST and SWIG will be deprecated and phased out. Internal Modification: call open/close only on the adapters that perform I/O. This makes the python wrapper simpler. BUGFIX: stack overrun in udpsrv Feature: cpsw_mem_dev: support 'offset' property when mapping a file descriptor. Bugfix: Ipath::parent() implementation was wrong; caused segfault. (merged from R3.5.branch) Bugfix: cpsw_bufq.cc: If multiple threads sleep in CEventBufSync::getSlot() some may never wake up! FIX: There was a subtle change in the implementation of YAML maps in yaml-cpp v0.6.2: When a non-existing key is looked up with YAML::Node operator[](const Key &k); then an 'invisible' new entry is added to the map. We can iterate through the new map and won't see this new entry (unless it was explicitly created e.g., by an assignment: 'map[key] = value;'. This behaviour was already the same in 0.5.3. What has **changed** however, is that under 0.6.3 this lookup operation **breaks** existing iterators, i.e, YAML::const_iterator my_itr( map.begin() ); YAML::const_iterator my_end( map.begin() ); if ( ! map[nonexisting_key] ) { // lookup of non-existing key broke iterators // under 0.6.2 -- it used to work fine under // 0.5.3... while ( my_itr != my_end ) { // !!!MAY SEGFAULT HERE!!! } } In order to perform a lookup which does not modify the map we must use ('const' attribute overload of operator) const YAML::Node operator[](const Key *k) const; which is IMHO very confusing and error-prone. Unfortunately the API lacks a 'find' member analogous to std::map's... Feature: Provide file/line info when loading YAML fails due to parser errors. Feature: When performing an RMW operation over SRP that spans multiple words then read back (up to a max.) multiple words in a single read operation. Feature: Support C++11; reduce dependency on boost if C++11 is used. Boost is still used internally but not visible from the API. Feature: Support SRP 'posted' writes. This is now the default. However, the write mode can be set from YAML. Future API additions could override the default for each individual SRP operations. Posted writes should be just fine, however. Interspersed reads always serve as synchronization points, i.e., all writes and reads over a single SRP VC are issued (and executed on target) strictly in order. Feature: NetIODev supports 'rssiBridge' property. When set then CPSW contacts the bridge's RPC service to learn the TCP port serving : on the target. I.e., if the 'normal' YAML says ipAddr: 192.168.2.10 ... UDP: port: 8198 RSSI: and is changed into ipAddr: 192.168.2.10 rssiBridge: cpu-b084-hp01 ... UDP: port: 8198 RSSI: then the code uses a RSSI bridge at cpu-b084-hp01 to proxy traffic to 192.168.2.10:8198 off that bridge. The RPC service takes care of remapping UDP to TCP ports in case multiple bridges are running (connecting to different targets). Feature: NetIODev supports 'socksProxy' property (SOCKS_PROXY env- var is also supported) for selecting a proxy. Feature: Added SOCKS support for TCP connection (code stolen from my implementation for EPICS. Feature: rssi_bridge enhancements: - added '-u' option to control for individual ports whether RSSI is to be used or not (for bare UDP ports). -> -p tunnels an UDP/RSSI connection via TCP -> -u tunnels a bare UDP connection via TCP - added connection handler. UDP side is only connected once a TCP connection is accepted. The old behavior (UDP side is connected to FPGA immediately) is available via '-C' option. This feature (*without* -C) is useful as it allows the bridge to be started with a standard set of ports. It is then up to the remote peer (which has the YAML) to decide which ports to actually use. Merge: FIX for depacketizer V2 (SOF bit sometimes not cleared in non-first fragments). Merge: depacketizer V2 support (from master) Merge: Set default for SRP retryCount to 0 if transport is RSSI or TCP Merge: CFreeList now supports allocate_shared() (single allocation from free-list) Convert IntFields with bitSize > 64 to be converted to (hex) strings without truncating them (when read as CString). Fixed MTU calculation for RSSI and DEPACK Support for native endianness (ScalVal) Bugfix: TDESTMux2: missing inintialization of class member causing segfault. Bugfix: IYamlFixup::findByName() corrupted YAML hierarchy. Bugfix: (in udpsrv, i.e., test code): incorrect use of lock guard lead to no mutex protection (in simulator only)! Bugfix: RSSI protocol module 'push' with absolute timeout would pop from underlying queue instead of pushing. Fix: test driver for streams over unreliable transport should use some margin of acceptable errors. This was set to 22% (builder API) but when the same test was run with a YAML hierarchy the corresponding option was not set to relax the acceptable error margin. (Merged from R3.5.branch.) R3.7.branch Feature: added 'getPath()', 'getConstPath()' to ICommand R3.6.6 Bugfix: cpsw_bufq.cc: If multiple threads sleep in CEventBufSync::getSlot() some may never wake up! R3.6.5 (merged) Guard: Reject newer YAML properties which require a more recent version of CPSW: depack/protocolVersion: rssiBridge socksProxy R3.6.4 Added i686 and zynq (arm) targets R3.6.3 Removed buildroot-2015 target R3.7.branch Bugfix: path was clobbered (incorrect NELMS) during 'explore' if tail was an array. Bugfix: protocol stack builder always used depacketizer if no SRP Pycpsw: release GIL while blocking to read/write a stream. (hopefull it is OK and python doesn't alter the buffer state; the code we're executing with the GIL unlocked is strictly non-python, of course) Feature: block all signals in newly created threads. Bugfix: (jira ESLCOMMON-178) when loading an IntField config from YAML and the IntField has an enum menu then providing numerical values in the config file didn't work. Changed IYamlFixup; the callback now gets two nodes passed in. The root node of the CPSW hierarchy and the top node (which might be outside of the root) Also: the python method name was changed from 'fixup' to '__call__' (to match c== operator()). R3.7.branch Feature: Added support for fragmentation (packetizer) of outgoing traffic. Protocol Stack: changed semantics of 'processOutput/processInput'. these can now 'edit' buffer chains in a more flexible manner. Feature: added 'emitNode' to yaml_cpp wrapper. Convert node hierarchy to string (which can be written to a file). Bugfix: proto_stack_builder::useDepack() should not set other params Moved 'getEncoding()' from IScalVal_Base to IVal_Base. Python: Stream.read() has an optional 'offset' argument (same as underlying IStream::read()) MemDev: FIX - read(NULL) means that the user wants to know if data are available; must return nonzero. Added support for thread priorities. All internal threads in the protocol stack can be configured (from YAML) with a priority (see doc/README.yamlDefinition). New features: a 'NullDev' which is not backed by anything. Useful for testing/debugging because any YAML hierarchy can be loaded w/o need for hardware (or a lot or memory as with MemDev that covers a large address space). Python: a minimal wrapper for yaml-cpp was added; enough to support basic fixups. Python: Added YamlFixup so that a fixup (LoadYamlFile etc.) can be written in python. NOTE: this requires yaml-cpp python bindings which must be implemented/obtained elsewhere, i.e., they are NOT part of cpsw. R3.6.1 Makefile fixes Added more targets to .PHONY: Recurse 'test' into SUBDIRS, POSTBUILD_SUBDIRS Moved 'test' target to rules.mak Let top-level 'makefile' use 'rules.mak' & friends R3.6.0 Feature/Fix: PYTHON: instantiate Streams via a context manager; i.e., streams can only be used inside a 'with' block! *** NOTE *** this is a python interface change; it is no longer possible to read from a newly created stream (Stream.create() now returns a context manager)! Instead, you must read from the block of a 'with' statement: with Stream.create() as s: s.read( buf ) Feature: derive IStream from IVal_Base; allows to obtain basic properties from the stream interface. R3.5.4 4-May-2017 Till Straumann (strauman) Bugfix: Path->toString() segfault UDP/TCP: ignore empty buffer chains (but don't deref!)
