A bug concerning bit comprehensions has been fixed in Cover. The bug was introduced in R13B03. (Thanks to Matthew Sackman.)

The coverage analysis tool cover has been improved when it comes to handling list and bit string comprehensions (a counter for each qualifier), bit syntax expressions (the Value and Size expressions), and try expressions (the body called Exprs in the Reference Manual). A few (not all) situations where several expressions are put on the same line are also handled better than before.

When loading Cover compiled code on remote nodes running code in the loaded module, a badarg failure was sometimes the result. This bug has been fixed.

The short-circuit operators andalso and orelse are now handled correctly by the coverage analysis tool cover (it is no longer checked that the second argument returns a Boolean value.)

cover now properly escapes greater-than and less-than characters in comments in HTML reports. (Thanks to Magnus Henoch.)

xref:start/1 does now allow anonymous XREF processes to be started

A bug in the Xref scanner has been fixed.

A bug in Fprof where the function 'undefined' appeared to call 'undefined' has been corrected.

The documentation has been updated so as to reflect the last updates of the Erlang shell as well as the minor modifications of the control sequence p of the io_lib module.

Superfluous empty lines have been removed from code examples and from Erlang shell examples.

tuple_size/1 and byte_size/1 have been substituted for size/1.

The coverage analysis tool cover now handles the short-circuit Boolean expressions andalso/2 and orelse/2 properly.

The cover tool could use huge amounts of memory when used in a distributed system.

Own Id: OTP-6758

Missing buffer-local declaration in erlang.el has been added. Before this fix there could arise problems in other emacs modes after visiting a buffer using the erlang mode.

Own Id: OTP-6721

Key-map for 'backward-delete-char-untabif updated to work properly with Xemacs.

Minor updates of Xref.

Minor Makefile changes.

"C-u C-c C-k" now does a compile with both "debug_info" and "export_all".

Own Id: OTP-6741

Changes due to internal interface changes in the erts application which are needed at compile-time. No functionality has been changed.

Own Id: OTP-6611 Aux Id: OTP-6580

Made change to support the function erlang-find-tag for xemacs and emacs-21.

Own Id: OTP-6512

Minor updates of xref for future compatibility.

eprof did not work reliably in the SMP emulator, because the trace receiver process could not process the trace messages fast enough. Therefore, eprof now blocks the other schedulers while profiling.

Own Id: OTP-6373

Fprof traces could become truncated for the SMP emulator. This bug has now been corrected.

Own Id: OTP-6246

eprof now works somewhat better in the SMP emulator.

Fixed some bugs in make:

make:files/1,2 can now handle a file in another directory as argument, similar to make:all/0,1.

When specifying a file name including the .erl extension in Emakefile, make:all/0,1 looked for the object code in the wrong place.

When specifying a file name including the .erl extension in Emakefile and some compile options for the file, make:files/0,1 did not use the options as it should do.

cover: When cover:stop() was called, the cover compiled code was not unloaded (as stated in the documentation) but simply marked as 'old'. This meant that processes lingering in (or with funs referencing to) the cover compiled code would survive even when the cover server and its ETS tables was terminated.

Now the cover compiled code is unloaded, meaning that processes lingering in/with references to it will be killed when cover:stop is called, instead of later crashing with badarg when trying to bump counters in ETS tables no longer existing.

Replaced call to deprecated function file:file_info/1 with call to filelib:is_dir/1 and filelib:is_regular/1 in tags.erl.

A bug in fprof profiling causing erroneous inconsistent trace failure has been corrected.

Emacs: erlang-man-function and erlang-man-module used a pattern matching to find the requested module that sometimes yielded unexpected results. For example, erlang-man-module file would display the man page for CosFileTransfer_File.

Some compiler warnings and Dialyzer warnings were eliminated in the Tools application.

When tracing to a port (which fprof does), there could be fake schedule out/schedule in messages sent for a process that had exited.

The cross reference tool xref did not handle the new fun M:F/A construct properly. This problem has been fixed.

Own Id: OTP-5653

The cover tool did not escape '<' and '>' not being part of HTML tags in HTML log files.

It is now possible to encrypt the debug information in beam files, to help keep the source code secret. See compile(3) for how to provide the key for encrypting, and beam_lib(3) for how to provide the key for decryption so that tools such as Debugger, xref, or cover can be used.

The beam_lib:chunks/2 functions now accepts an additional chunk type 'compile_info' to retrieve the compilation information directly as a term. (Thanks to Tobias Lindahl.)

The cover tool could not analyze empty modules on module level.

Own Id: OTP-5418

The xref analysis locals_not_used could return too many functions. This problem has been fixed.

The cover tool could not always compile parse transformed modules. This problem has been fixed.
