2016-03-17systools_make: Add commonly used modules to mandatory_modules/0Björn Gustavsson
Add commonly used modules to the list of modules in mandatory_modules/0. Having those modules listed will potentially help the 'init' module to load them in parallel during start-up.
2016-03-17compile: Pre-load compiler modules when invoked from 'erlc'Björn Gustavsson
Slightly speed up 'erlc' by pre-loading the modules used by the compiler. Write a test case to ensure that the correct set of modules are loaded.

2016-03-16code_server: Normalize the pathnames for all loaded modulesBjörn Gustavsson
On Windows, the pathnames for modules that are loaded early are returned with mixed backslashes and slashes: 1> code:which(lists). "C:\\Program Files\\erl8.0/lib/stdlib-2.7/ebin/lists.beam" 2> Modules loaded later are fully normalized. When starting the code_server, normalize the pathnames for all modules that have been loaded so far.

2016-03-14Make distribution failures during start-up easier to readBjörn Gustavsson
When an attempt is made to start a distributed Erlang node with the same name as an existing node, the crash reports for several supervisors would be displayed. Only the first line contains useful information. The verbiage is annoying for old hands and could easily scare newcomers away for good. For all the common distribution failures during start-up, write a simple message and terminate the emulator using halt/1. Here is an example of what will be printed: Protocol 'inet_tcp': the name somename@somehost seems to be in use by another Erlang node

2016-03-11Don't throw exceptions from rpc:call() and rpc:block_call()Björn Gustavsson
The documentation for rpc:call() says: Evaluates apply(Module, Function, Args) on the node Node and returns the corresponding value Res, or {badrpc, Reason} if the call fails. What is not said that rpc:call() can generate an exception if the 'rex' process on the other node is killed: (kalle@host)1> Rex = rpc:call(arne@host, erlang, whereis, [rex]). <6937.14.0> (kalle@host)2> rpc:call(arne@host, erlang, exit, [Rex,kill]). ** exception exit: {killed, {gen_server,call, [{rex,arne@host}, {call,erlang,exit,[<6937.14.0>,kill],<0.33.0>}, infinity]}} in function rpc:rpc_check/1 (rpc.erl, line 361) On the other hand, if the other node shuts down for some other reason, we'll get a {badrpc,nodedown} result: (kalle@host)5> rpc:call(arne@host, erlang, halt, []). {badrpc,nodedown} There does not seem to be any reason to handle the two cases differently. If the 'rex' process is terminated on the other node, it will shut down shortly thereafter. Therefore, change rpc:call() and rpc:block_call() to always return {badrpc,Reason} is the call fails: (kalle@host)1> Rex = rpc:call(arne@host, erlang, whereis, [rex]). <6937.14.0> (kalle@host)2> rpc:call(arne@host, erlang, exit, [Rex,kill]). {badrpc,{'EXIT',{killed,{gen_server,call, [{rex,arne@host}, {call,erlang,exit,[<7126.14.0>,kill],<0.33.0>}, infinity]}}}}

2016-03-10Improved scheduler suspend functionalityRickard Green
- The calling process is now suspended while synchronizing scheduler suspends via erlang:system_flag(schedulers_online, _) and erlang:system_flag(multi_scheduling, _), instead of blocking the scheduler thread in the BIF call waiting for the operation to synchronize. Besides releasing the scheduler for other work (or immediate suspend) it also makes it possible to abort the operation by killing the process. - erlang:system_flag(schedulers_online, _) now only wait for normal schedulers to complete before it returns. This since it may take a very long time before all dirty schedulers suspends. - erlang:system_flag(multi_scheduling, block_normal|unblock_normal) which only operate on normal schedulers has been introduced. This since there are use cases where suspend of dirty schedulers are not of interest (hipe loader). - erlang:system_flag(multi_scheduling, block) still blocks all dirty schedulers as well as all normal schedulers except one since it is hard to redefine what multi scheduling block means. - The three operations: - changing amount of schedulers online - blocking/unblocking normal multi scheduling - blocking/unblocking full multi scheduling can now be done in parallel. This is important since otherwise a full multi scheduling block would potentially delay the other operations for a very long time.

2016-03-10beam_block: Eliminate unsafe optimizationBjörn Gustavsson
Consider this code: %% Start of block get_tuple_element Tuple 0 Element get_map_elements Fail Map [Key => Dest] . . . move Element UltimateDest %% End of block Fail: %% Code that uses Element. beam_block (more precisely, otp_tuple_element/1) would incorrectly transform the code to this: %% Start of block get_map_elements Fail Map [Key => Dest] . . . get_tuple_element Tuple 0 UltimateDest %% End of block Fail: %% Code that uses Element. That is, the code at label Fail would use register Element, which is either uninitalized or contains the wrong value. We could fix this problem by always keeping label information at hand when optimizing blocks so that we could check the code at the failure label for get_map_elements. That would require changes to beam_block and beam_utils. We might consider doing that in the future if it turns out be worth it. For now, I have decided that I want to keep the simplicity of blocks (allowing them to be optimized without keeping label information). That could be achieved by not including get_map_elements in blocks. Another way, which I have chosen, is to only allow get_map_elements as the first instruction in the block. For background on the bug: c288ab8 introduced the beam_reorder pass and 5f431276 introduced opt_tuple_element() in beam_block.
