2010-02-08Add runtime option to enable/disable lcnt statsBjörn-Egil Dahlberg
Add erts_debug:lock_counters({copy_save, bool()}). This option enables or disables statistics saving for destroyed processes and ets-tables. Enabling this might consume a lot of memory. Add id-numbering for lock classes which is otherwise undefined.

2010-02-08Add lock profiling toolBjörn-Egil Dahlberg
The Lock profiling tool, lcnt, can make use of the internal lock statistics when the runtime system is built with this feature enabled. This provides a mechanism to examine potential lock bottlenecks within the runtime itself.
2010-02-08Merge branch 'sc/sctp-connect-nowait' into ccase/r13b04_devErlang/OTP
* sc/sctp-connect-nowait: Implement a non-blocking SCTP connect OTP-8414 There are new gen_sctp:connect_init/* functions that initiate an SCTP connection without blocking for the result. The result is delivered asynchronously as an sctp_assoc_change event. (Thanks to Simon Cornish.)
2010-02-08Merge branch 'gc/hipe_darwin_amd64' into ccase/r13b04_devErlang/OTP
* gc/hipe_darwin_amd64: Fix hipe memory allocation problems on darwin/amd64 Porting x86 darwin fixes to amd64 darwin hipe asm/m4 code Automatically enable hipe for darwin/amd64 builds Allow configure to enable_hipe for darwin/amd64 builds OTP-8416 HiPE now works in the 64-bit emulator on Mac OS X. (Thanks to Geoff Cant.)

tile-cc 2.0.1.78377 when compiling the runtime system.
2010-02-08OTP-8323 Cross compilation improvements and other build systemRickard Green
improvements. Most notable: Lots of cross compilation improvements. The old cross compilation support was more or less non-existing as well as broken. Please, note that the cross compilation support should still be considered as experimental. Also note that old cross compilation configurations cannot be used without modifications. For more information on cross compiling Erlang/OTP see the $ERL_TOP/xcomp/README file. Support for staged install using <url href="http://www.gnu.org/prep/standards/html_node/DESTDIR.html">D ESTDIR</url>. The old broken INSTALL_PREFIX has also been fixed. For more information see the $ERL_TOP/README file. Documentation of the release target of the top Makefile. For more information see the $ERL_TOP/README file. make install now by default creates relative symbolic links instead of absolute ones. For more information see the $ERL_TOP/README file. $ERL_TOP/configure --help=recursive now works and prints help for all applications with configure scripts. Doing make install, or make release directly after make all no longer triggers miscellaneous rebuilds. Existing bootstrap system is now used when doing make install, or make release without a preceding make all. The crypto and ssl applications use the same runtime library path when dynamically linking against libssl.so and libcrypto.so. The runtime library search path has also been extended. The configure scripts of erl_interface and odbc now search for thread libraries and thread library quirks the same way as erts do. The configure script of the odbc application now also looks for odbc libraries in lib64 and lib/64 directories when building on a 64-bit system. The config.h.in file in the erl_interface application is now automatically generated in instead of statically updated which reduces the risk of configure tests without any effect.

2010-02-07Merge branch 'ta/code_clash_ez' into ccase/r13b04_devErlang/OTP
* ta/code_clash_ez: code_SUITE: add missing is_list(Config) guard Add tests for code:clash/0 Fix handling of archive (.ez) files in code:clash/0 OTP-8413 code:clash/0 now looks inside archives (.ez files). (Thanks to Tuncer Ayaz.)
2010-02-06Fix hipe memory allocation problems on darwin/amd64Geoff Cant
HiPE on amd64 needs to be able to allocate memory in the 0x20000000+ range so that compiled code will be addressable with 32bit pointers (when sign extended). By default, when building 64bit executables on OS X, PAGEZERO occupies the first 4GB of virtual memory. The PAGEZERO segment cannot be mmap(ed) or vm_allocate(d) into. To avoid this problem we use the -pagezero_size linker flag to reduce the size of PAGEZERO and free up the 0x20000000+ space.
2010-02-06Porting x86 darwin fixes to amd64 darwin hipe asm/m4 codeGeoff Cant
Compared to GNU as, Mac OS X's assembler uses different directives for text and global sections, and omits type and size directives entirely. We also need to mangle symbol names in order to allow linking with C object files.

2010-02-06Implement a non-blocking SCTP connectSimon Cornish
This patch adds a new set of functions - gen_sctp:connect_init/* that initiate an SCTP connection without blocking for the result. The result is delivered asynchronously as an sctp_assoc_change event. The new functions have the same API as documented for gen_sctp:connect/* with the following exceptions: * Timeout is only used to supervise resolving Addr (the peer address) * The possible return values are ok | {error, posix()} The caller application is responsible for receiving the #sctp_assoc_change{} event and correctly determining the connect it originated from (for example, by examining the remote host and/or port). The application should have at least {active, once} or use gen_sctp:recv to retrieve the connect result. The implementation of gen_sctp:connect suffers from a number of shortcomings which the user may avoid by using gen_sctp:connect_init and adding code to receive the connect result. First, irrespective of the Timeout value given to gen_sctp:connect, the OS attempts and retries the SCTP INIT according to various kernel parameters. If the Timeout value is shorter than the entire attempt then the application will still receive an sctp_assoc_change event after the {error, timeout} is returned from the initial call. This could be somewhat confusing (either to the application or the designer!) especially if the status is comm_up. Subsequent calls to connect before the OS has finished this process return {error, ealready} which may also be counter-intuitive. Second, there is a race-condition (documented in comments in inet_sctp.erl) that can cause the wrong sctp_assoc_change record to be returned to an application calling gen_sctp:connect. The race seriously affects connection attempts when using one-to-many sockets.

2010-02-03OTP-8058 The GUI parts are rewritten to use wxWidgets. Thanks OlleHåkan Mattsson
Mattsson! For the time being it is still possible to use the old GS based version of the tool, but it is deprecated. The wxWidgets based version is started by default. A new tutorial has been added to the documentation. It is based on Jayson Vantuyl's article http://souja.net/2009/04/making-sense-of-erlangs-event-tracer.htm l. The functions et:trace_me/4 and et:trace_me/5 has been introduced in order to replace the deprecated functions et:report_event/4 and et:report_event/5. Hopefully the new names makes it a little more obvious what the intended usage of the functions are. A print function has been added to the GUI, in order to enable printing of sequence charts. More functionality for hiding unwanted events has been added to the GUI. The max_events, hide_unknown and display_mode configuration parameters to et_viewer is not used any more. Now the event cache in the Viewer only contains those events that actually are displayed in the GUI. Some minor bugs has been fixed. Such as a cleaning up trace patterns at termination and displaying events with detail level 100.
