This came from supervisor:delete_child and happened when the rb_server has not yet terminated when this function was called. Instead of having a separate gen_server call to rb_server for stopping the process, supervisor:terminate_child is now called. This is a synchronous function - i.e. it waits for the process to actually terminate before it returns.</p> <p> A file descriptor leak in rb:scan_files is corrected. The index file was never closed after reading.</p> <p> A mismatch in the behavior of rb:filter, when filter included 'no', is corrected. Such filters will now return *all* non-matching reports, not only the 'proplist' reports.</p> <p> Own Id: OTP-9149</p> </item> <item> <p> Start and end date for rb:filter/2 was specified as {{Y-M-D},...} in the help text instead of {{Y,M,D},...}. This has been corrected.</p> <p> Own Id: OTP-9166</p> </item> <item> <p> If some, but not all, of the sasl environment variables related to the log_mf_h error handler were missing sasl would successfully start but silently skip starting log_mf_h. This is corrected so sasl startup will now fail if one or two of the three variables are given. If none of the variables are given, sasl will start as before without starting log_mf_h.</p> <p> Own Id: OTP-9185</p> </item> </list> </section> <section><title>Improvements and New Features</title> <list> <item> <p> Change default behaviour to not check src code when creating release</p> <p> Add new option <c>src_tests</c> to systools:make_script and systools:make_tar.

If the start type is none, no apply line is included in the relup. If the start type is load, the relup includes instruction to only load the application. Otherwise, the relup includes an instruction to start the application to the according type.</p> <p> The fix is implemented by adding a new parameter to the add_application high level appup instruction. This new parameter is documented in appup(5).</p> <p> Own Id: OTP-9097</p> </item> </list> </section> </section> <section><title>SASL 2.1.9.2</title> <section><title>Fixed Bugs and Malfunctions</title> <list> <item> <p>In R13B04 sys:get_status was modified to invoke format_status/2 in the callback module if the module exports that function. This resulted in a change to the term returned from calling sys:get_status on the supervisor module, since supervisor is a gen_server and gen_server exports format_status. The sasl release_handler_1 module had a dependency on the pre-R13B04 term returned by sys:get_status when invoked on a supervisor, so the R13B04 change broke that dependency.</p> <p>This problem has been fixed by change release_handler_1 to handle both the pre-R13B04 and R13B04 terms that sys:get_status can return from a supervisor.</p> <p> Own Id: OTP-8619 Aux Id: seq11570 </p> </item> </list> </section> </section> <section><title>SASL 2.1.9.1</title> <section><title>Improvements and New Features</title> <list> <item> <p>Use an infinity timeout in all calls to <c>gen_server:call()</c> in the <c>sasl</c> application.</p> <p> Own Id: OTP-8506 Aux Id: seq11509 </p> </item> </list> </section> </section> <section><title>SASL 2.1.9</title> <section><title>Improvements and New Features</title> <list> <item> <p> The <c>re:grep/1</c> function now uses the '<c>re</c>' module instead of the deprecated '<c>regexp</c>' module.
