This document describes the changes made to the Observer application.
Fixed statusbar on Windows

crashdump_viewer would crash if the owner of a timer was specified as the process' registered name. This has been corrected.

etop trace handler now works in smp environment (Thanks to Péter Gömöri)

Application upgrade (appup) files are corrected for the following applications:
A new test utility for testing appup files is added to test_server. This is now used by most applications in OTP.

Use "open" as default browser for crashdump viewer on Mac OS X. Thanks to Magnus Henoch.

Fix observer table viewer crash on formatting improper lists. Thanks to Andrey Tsirulev
Own Id: OTP-10931
Postscript files no longer needed for the generation of PDF files have been removed.
Own Id: OTP-11016
Add processes state view in observer. Thanks to Eric Pailleau.
Own Id: OTP-11136
Where necessary a comment stating encoding has been added to Erlang files. The comment is meant to be removed in Erlang/OTP R17B when UTF-8 becomes the default encoding.
Own Id: OTP-10630
The module name in the link to the detail page for each loaded module was earlier not URL encoded. If the module name contained e.g. a # this could cause the crashdump viewer to crash when opening the link. This has been corrected.

Escape control characters in Table Viewer
Similar behaviour to old tv. Objects in tables supposed to be printed in a single line and it looks ugly when a [...,10,...] integer list creates a new-line. Fix Table Viewer search crash on new|changed|deleted rows.
Fix Table Viewer crash after a 'Found' -> 'Not found' search sequence
Start position was lost after a 'Found' -> 'Not found' search sequence leading an undefined position in the next search. Thanks to Peti Gömori

Add missing observer modules to observer.app.src. Thanks to Tuncer Ayaz.

Make Table Viewer search a bit faster
Edit table row in a multiline text dialog. Thanks to Peti Gomori.

Allow tracing on bifs.
Ask epmd for local nodes, and remember users last input in connect.
Fix crashes when a table or process information could not be retrieved.

The file trace port to which the IP trace client relays all traces from diskless nodes was not flushed and closed properly on ttb:stop. This has been corrected.

Do not install *.bat files on non-win32 machines (Thanks to Hans Ulrich Niedermann)
Own Id: OTP-9515
The time needed for loading a crashump into the crashdump viewer would earlier grow exponentially with the size of the crashdump file. Reading a file of 20M would take a couple of minutes, and for a dump of 250M it would take between 1 and 2 hours. This has been solved.
Earlier, all processes, timers, funs or ets-tables would be loaded into the memory of the crashdump viewer node before sending it on to the web server. This has been changed and the pages are now sent to the web server in chunks.
A security function in newer web browsers prevents a full file path to be sent from an HTML file input field, i.e. the field needed to implement the "Browse" button when loading a file into the crashdump viewer. To overcome this, the file input field is no longer used. Instead a normal text input field is used, and the user needs to manually insert the complete file path. For convenience, a shell script and a batch file are added to the observer application. These can be used to start the crashdump_viewer and a browser and load a file - with the file name given from the command line. The shell script and batch file are called cdv and cdv.bat respectively, and can be found in the priv dir of the observer application.

Misc updates
Own Id: OTP-8456
Major improvements of the Erlang distribution for Erlang runtime systems with SMP support. Previously distribution port locks were heavily contended, and all encoding and decoding for a specific distribution channel had to be done in sequence. Lock contention due to the distribution is now negligible and both encoding and decoding of Erlang messages can be done in parallel.
The old atom cache protocol used by the Erlang distribution has been dropped since it effectively prevented all parallel encoding and decoding of messages passed over the same distribution channel.
A new atom cache protocol has been introduced which isolates atom cache accesses and makes parallel encoding and decoding of messages passed over the same distribution channel possible. The new atom cache protocol also use an atom cache size 8 times larger than before. The new atom cache protocol is documented in the ERTS users guide.
Erlang messages received via the distribution are now decoded by the receiving Erlang processes without holding any distribution channel specific locks. Erlang messages and signals sent over the distribution are as before encoded by the sending Erlang process, but now without holding any distribution channel specific locks during the encoding. That is, both encoding and decoding can be and are done in parallel regardless of distribution channel used.
The part that cannot be parallelized is the atom cache updates. Atom cache updates are therefore now scheduled on the distribution port. Since it is only one entity per distribution channel doing this work there is no lock contention due to the atom cache updates.
The new runtime system does not understand the old atom cache protocol. New and old runtime systems can however still communicate, but no atom cache will be used.
