This is used by test_server and common_test when it is safe to assume that the node will be terminated after the test anyway. The purpose is to avoid processes crashing when re-loading the original beam if the processes is still running old code.</p> <p> Remote nodes will now continue to count code coverage if the connection to the main node is broken. Earlier, a broken connection would cause the cover_server on the remote node to die and thus any still cover compiled modules would cause process crash when trying to insert cover data in ets tables that used to exist on the cover_server. The new functionality also involves synchronization with the main node if the nodes are reconnected.</p> <p> *** POTENTIAL INCOMPATIBILITY ***</p> <p> Own Id: OTP-10523 Aux Id: OTP-10427 </p> </item> <item> <p>Where necessary a comment stating encoding has been added to Erlang files.

This unexpected leftover could be eliminated if erlang:demonitor/2 with option flush would be used in certain points</p> <p> Own Id: OTP-9694</p> </item> <item> <p> Add deps as erlang-flymake include directory.</p> <p> Update erlang-flymake to recognize the "deps" folder as an include directory. This makes erlang-flymake compatible with the rebar dependency management tool's default folder structure, which puts included dependencies in "deps".(Thanks to Kevin Albrecht)</p> <p> Own Id: OTP-9791</p> </item> </list> </section> <section><title>Improvements and New Features</title> <list> <item> <p>Variables are now now allowed in '<c>fun M:F/A</c>' as suggested by Richard O'Keefe in EEP-23.</p> <p>The representation of '<c>fun M:F/A</c>' in the abstract format has been changed in an incompatible way. Tools that directly read or manipulate the abstract format (such as parse transforms) may need to be updated. The compiler can handle both the new and the old format (i.e. extracting the abstract format from a pre-R15 BEAM file and compiling it using compile:forms/1,2 will work). The <c>syntax_tools</c> application can also handle both formats.</p> <p> *** POTENTIAL INCOMPATIBILITY ***</p> <p> Own Id: OTP-9643</p> </item> <item> <p> Tuple funs (a two-element tuple with a module name and a function) are now officially deprecated and will be removed in R16. Use '<c>fun M:F/A</c>' instead. To make you aware that your system uses tuple funs, the very first time a tuple fun is applied, a warning will be sent to the error logger.</p> <p> Own Id: OTP-9649</p> </item> <item> <p> Eliminate use of deprecated regexp module</p> <p> Own Id: OTP-9810</p> </item> </list> </section> </section> <section><title>Tools 2.6.6.5</title> <section><title>Fixed Bugs and Malfunctions</title> <list> <item> <p> Teach the emacs mode to compile yecc and leex files</p> <p> If visiting a .yrl or .xrl file in emacs with erlang-mode, then the `erlang-compile' function (normally bound to C-c C-k), now knows how to compile yecc and leex files, and then, if that compilation succeeds, also compiles the resulting .erl files.</p> <p> Also introduce a `erlang-compile-command-function-alist' to make it possible to hook in other functions for computing compilation commands/expressions, depending on file name. (Thanks to Tomas Abrahamsson )</p> <p> Own Id: OTP-9503</p> </item> </list> </section> <section><title>Improvements and New Features</title> <list> <item> <p> Bugs in xref(3) have been fixed.

It does not affect the return value.</p> <p> (Thanks to Sam bobroff)</p> <p> Own Id: OTP-9179</p> </item> <item> <p> add user specified compiler options on form reloading</p> <p> In order to be able to test non-exported functions from another (test) module it is necessary to compile the specific module (at least during the test phase) with the export_all compiler option. This allows complete separation of testing and productive code. At the moment it is not possible to combine this with a test code coverage using the cover module. The problem is that when cover compiling a module using cover:compile_* the code is reloaded into the emulator omitting/filtering the passed user options. In my example above the export_all option would be removed and the non-exported functions cannot be called any more. (Thanks to Tobias Schlager)</p> <p> Own Id: OTP-9204</p> </item> <item> <p> Inhibit electric newline after "->" when inside a type spec</p> <p> The Erlang mode for Emacs inserts a newline after every "->", which saves you one keystroke when writing a function, but that is inappropriate when writing a type spec, as you'd normally keep the spec on one line. This change inhibits the automatic insertion when the current line starts with "-spec" or "-type".(Thanks to Magnus Henoch)</p> <p> Own Id: OTP-9255</p> </item> <item> <p> Add a check logic to prevent file descriptor leak</p> <p> cover module handle files as raw in export and import. Assert counts of ports are the same at the beginning and at the end of the test case.(Thanks to Shunichi Shinohara)</p> <p> Own Id: OTP-9300</p> </item> </list> </section> </section> <section><title>Tools 2.6.6.3</title> <section><title>Fixed Bugs and Malfunctions</title> <list> <item> <p> Declare indentation options as "safe" in erlang-mode for Emacs</p> <p> Emacs has a facility for setting options on a per-file basis based on comments in the source file. By default, all options are considered "unsafe", and the user is queried before the variable is set. This patch declares the variables erlang-indent-level, erlang-indent-guard and erlang-argument-indent to be safe, if the value specified in the source file is valid.</p> <p> Such declarations usually look like this:</p> <p> %% -*- erlang-indent-level: 2 -*-</p> <p> and appear on the first line of the file. (thanks to Magnus Henoch)</p> <p> Own Id: OTP-9122</p> </item> </list> </section> <section><title>Improvements and New Features</title> <list> <item> <p> Cover has been improved to take less memory and allow parallel analysis of cover data. Data collection from nodes is now done in parallel and it is now possible to issue multiple analyse and analyse_to_file requests at the same time. A new function call async_analyse_to_file has also been introduced, see the documentation for more details.</p> <p> Own Id: OTP-9043 Aux Id: seq11771 </p> </item> </list> </section> </section> <section><title>Tools 2.6.6.2</title> <section><title>Fixed Bugs and Malfunctions</title> <list> <item> <p>eprof: API sort mismatch has now been fixed. </p> <p> Own Id: OTP-8853</p> </item> <item> <p> eprof: fix division by zero in statistics</p> <p> Own Id: OTP-8963</p> </item> </list> </section> </section> <section><title>Tools 2.6.6.1</title> <section><title>Fixed Bugs and Malfunctions</title> <list> <item> <p> <c>cover</c> will now show ampersand characters in the source code correctly.
