ebusd/ChangeLog.md

next version (2.0.0)

Breaking Changes

• automatic configuration file selection by querying device identification ("--scanconfig").
  Previous configuration files are still usable, but only without the "--scanconfig" command line parameter to ebusd (unless the files are renamed).

Bug fixes

• avoid multiple identical derived messages
• return "empty" for queries without result (e.g. grab result)
• fix for stopping main loop in rare cases
• fix for extracting default circuit name from CSV file name
• fix for using pselect
• fix for finishing active request when own master address reception timed out
• fix for some memory issues
• fix for closing serial device that is no tty
• fix for dumping message definition

Features

• respond to broadcast "write" command with "done broadcast"
• prepared for full file check with overlapping names and message keys
• added replacement value for date/time types
• extended "info" command with seen addresses, scan state, and loaded CSV file
• improved CSV file check
• insert index suffix extracted from CSV file name when applying defaults (format "ZZ.CCCCC[.index].csv")
• added support for MACH architecture (Mac OS)
• use empty condition messagename for referencing scan message
• allow read and write message definitions having the same ID
• add hint to decoding problems in "read" and "write" if answer was retrieved successfully
• added script for converting "grab result" to CSV
• exclusively lock serial device to prevent simultaneous access by another process
• extended "-i" parameter of "find" command to accept further ID parts

1.3.0 (2015-10-24)

Breaking Changes

• started with a new git repository for working on 2.0 version (previous repository was renamed to ebusd1)
• added support for conditional message definitions based on other message values

Bug fixes

• fix for numeric parsing of empty string
• allow HTTP port query string keys without value
• fix for thread cleanup
• update last message update time when actively sending it
• trim CSV lines and fields
• corrected derivation of field name, comment and unit in templates
• check invalid divisor/values for string and value list based types
• fix for overriding destination address in read command
• fix for cached master data

Features

• new "read" option "-n" for retrieving name/value pairs in numeric form
• new "find" option "-e" for exactly matching name and optional circuit (ignoring case)
• new "find" optipn "-F" for listing messages in CSV format with selected columns only
• added numeric, verbose, and required options to JSON and use "null" for unset or replacement value
• allow static ".json" files being served by HTTP port
• allow passing raw value when writing name/value pairs
• enhanced static HTML user interface to dynamic
• added possiblity to use a different name for referenced field template
• added data type HCD (for Ochsner)
• added base type TTH (truncated time with 30 minutes resolution)
• added base type VTM (reverse HTM)
• added log entry for scan completion
• automatically invalidate cached data of messages with same name+circuit (ignoring level)
• added "info" command
• added circuit and name to verbose "read" output
• added option to pass additional input data to "read" command
• added messages without dedicated destination and cached data decoding error to "find" result
• new "write" option "-d" for overriding destination address
• allow CSV file name to define default destination address and circuit name (format "ZZ.CCCCC.csv") and if present, concat default circuit name and security suffix (circuit name in CSV starting with "#")

1.2.0 (2015-05-25)

Bug fixes

• corrected missing newline in ebusctl
• avoid updating last message change time when only the querying master was modified
• notify running requests on device error

Features

• new command line option "--readonly" for read-only access to the bus
• added support for retrieving data as JSON and additional files via optional HTTP port
• added first version of static HTML user interface (to be extended to a dynamic one later)
• new "read" option "-h" for sending hex read messages
• new "read" option "-p PRIO" for setting the poll priority of a message

1.1.0 (2015-03-28)

Bug fixes

• return passive messages returned in "read" regardless of their age
• corrected divisor for chains of derived number types
• corrected master number calculation (no influence on any behaviour)
• fixed signed char warning on some compilers
• corrected minimum lock count according to spec.
• differentiate between valid empty result and not found field name
• fixed scanning for messages in subdirectories for certain file systems (thanks to joltcoke)
• allow mixing references to base types and templates in message definition
• renamed "class" to "circuit" in commands and message definition
• fixed reading cached values
• extended max allowed data length to 25 (spec says 16)

Features

• new command line option "--dumpconfig" for dumping message configurations
• new "find" command option "-f" for retrieving message configurations in CSV format
• new "find" command option "-i PB" to filter messages on primary command byte
• extended "read" command "FIELD" argument with optional ".N" for retrieving the N''th field with that name
• new "write" command option "-c" for compatibility with "read" and "find"
• automatically detect number of masters on the bus and add to "state" command
• support reciprocal divisor
• cache symbols instead of formatted strings. this allows retrieval of individual fields and verbose read from cache

• shortened manufcaturer names for "scan"
• allow specifying multiple destination addresses in message definition and defaults
• added Arch Linux PKGBUILD scripts (thanks to cogano)
• new "read" command option "-d ZZ" for overriding destination address (e.g. for manual scan)
• allow message definitions without any field

• added support for AUTO-SYN generation (experimental!)
• added "grab" command for collecting and reporting seen unknown messages

Changed files

https://github.com/john30/ebusd/compare/v1.0.0...v1.1.0

1.0.0 (2015-02-18)

Breaking Changes

This is the first version of the completely reworked ebusd since October 2014.

Bug fixes

A lot of problems were fixed, such as memory leaks and segmentation faults.

Features

The daemon is now fully aware of the eBUS protocol and future versions will also support addressing a running daemon as answering master/slave. The main new feature is a completely rewritten configuration file engine, which allows the use of templates and defaults and thus simplifies the configuration files a lot. On the client side, a lot of commands have been added, such as "listen" (automatically send changed values listened to or polled), "find", and "state".
