[ecasound-list] [ecasound] latest changes; cosmetic changes, log-history, etc

[Kai V. <kve...@ec...>]

Hello everyone,

I've today commited quite extensive changes to the CVS-tree. The diff
between 2.3.5 and CVS HEAD is already over 9000 lines. Fortunately most of
the changes are cosmetic and do not affect functionality in any way (IOW,
there should be only few if any bugs introduced by these changes). Some
highlights:

* Log message history. The EIAM command 'int-log-history' shows
  you N recent log messages printed via Ecasound subsystem, and
  'int-set-log-history-length' sets the buffer size.
  
  This should be a very useful tool for debugging ECI scripts
  and apps: issue int-log-history at the place when something
  odd happens and ta-daa, you see the whole log of what happened.

* Cosmetic changes to ecasound output. In the interactive mode
  (does not affect wellformed output or -D), Ecasound now wraps
  all lines so that they fit into 74 columns. I've copied the
  "... " prefix from the python interpreter to mark lines that
  are spread over multiple lines.

* Code added to analyze problems with chainsetups. If you
  now make common errors like:
  ecasound -i foo.wav -i foo.bar -o rtnull
  or
  ecasound -a:1 -i foo.wav -a:2 -i bar.wav -o rtnull
  .. ecasound will try to explain what is wrong with the
  configurations. This is realted to edi-40, "Update to error and warning 
  reporting mechanisms.".

A new snapshot including all the new stuff is available at:

And here's the whole list of changes since 2.3.5:

	- edi-entries: edi-40 progress
	- added: support for having commas in arguments by escaping 
	 	 them with a backslash (example: "ai-add foo\,bar.wav")
	- added: pretty-printing of ecasound output; wrap output so
		 so that all lines fit into 74 columns; does not affect
		 wellformed output mode nor stderr output (-D)
	- added: new section about handling commas in filenames to 
		 Ecasound User's Guide
	- added: eiam - new 'int-log-history' command to query 
	 	 recent log messages sent by libecasound; this is a very
		 useful tool for debugging ECI scripts and apps
	- added: eiam - new 'int-set-log-history-length' command to set
		 log history length; default to 5 items
	- changed: more helpful messages explain why a chainsetup 
		   cannot be connected to the engine
	- changed: EIAM - when returning a list of strings, replace all 
		   commas with semi-colons in the string items to avoid 
		   ambiguity in parsing
	- changed: new default debug level of 271
	- fixed: correctly interpret EIAM command arguments containing
	         whitespace (example: "ai-add foo bar.wav")
	- fixed: denormal problems in filter and delay operators
	- fixex: setting radius params of -etc comb filter
	- fixed: make check target in readline-4.0 subdir
	- fixed: avoid segfault when receiving a bufsize or srate
		 changed event from JACK; ecasound cannot change bufsize 
		 or srate changes on the fly, but at least it now fails 
		 gracefully
	- fixed: always pass filename (%f) as one parameter to the 
		 external apps; fixed remaining cases with mp3s, oggs, 
	         which have spaces in the filename
