2016-04-01rpc: Remove functions deprecated in R12BBjörn Gustavsson
2016-03-31code: Remove 'bad_path' error code from set_path/1Björn Gustavsson
code:set_path/1 no longer returns {error,bad_path} (an exception will be thrown instead).
2016-03-31Update Kernel documentationBjörn Gustavsson
Language cleaned up by technical writers from Combitech. Proofreading and corrections by Björn Gustavsson and Hans Bolinder.
2016-03-30inet_SUITE: Handle pointtopoint devices in getifaddrs/1Björn Gustavsson
2016-03-30file_SUITE: Increase timetrap for large_write/1Björn Gustavsson
In 9870d22b2401b, the timetrap for large_write/1 was accidentally reduced from the default 30 minutes to only 1 minute. That is not enough for some older computers.
2016-03-30inet_SUITE: Handle {error,enoent} in simple_netns_openBjörn Gustavsson
Allow an open operation to fail with {error,enoent}. That will happen if the executable has compiled-in support for netns, but the computer has not been configured for netns.
2016-03-24inet_SUITE: Handle missing SCTP support in simple_netns/1Björn Gustavsson
2016-03-23file_name_SUITE: Improve handling of missing permission for link creationBjörn Gustavsson
On modern versions of Windows, creation of symlinks is supported, but our test machines usually don't have permissions for creating symlinks. Therefore, the has_links/0 that attempts to predict whether link creation will work by testing version numbers will not do any good. Refactor the code so that test cases don't fail when links cannot be created because of missing permissions.
2016-03-23file_name_SUITE: Remove useless put/2 to process dictionaryBjörn Gustavsson
There is never any corresponding get/1.
2016-03-23file_name_SUITE: Handle the case that HOMEPATH may not be setBjörn Gustavsson
Seems that it can happen on Windows.
2016-03-23code_SUITE: Skip on_load_embedded/1 if no symlinksBjörn Gustavsson
On Windows, we might not have permission to create symlinks. Skip the test case instead of failing.
2016-03-23gen_sctp_SUITE: Skip most SCTP test cases on Solaris before 5.12Björn Gustavsson
On old Solaris versions, many gen_sctp test cases fail. It is not clear whether the implementation or the test cases or both must be fixed. The number of failed test cases is a problem, as other failed test cases in the Kernel application might not be noticed. For now, skip most test gen_sctp test cases on old Solaris platforms, until the day that someone can mend the tests case and/or implementation (or test machines die). Keep a few smoke test cases.
2016-03-23heart_SUITE: Increase timeout in restart/1Björn Gustavsson
2016-03-23heart_SUITE: Use unique node namesBjörn Gustavsson
Avoid interference between test cases.
2016-03-23init_SUITE: Quote pathname that may contain a spaceBjörn Gustavsson
On Windows, the pathname is likely to start with "C:/Program Files".
2016-03-23gen_tcp_misc_SUITE: Clean up send_timeout{_active}/1Björn Gustavsson
Eliminate gratuitous use of funs. Don't limit the send attempts to 1000; it might not be enough. Rely on four minut timetrap to fail the test case if there will never be a send timeout error.
2016-03-23Clean up the determination of the hostnameBjörn Gustavsson
2016-03-18kernel: Reduce sendfile fallback chunk sizeLukas Larsson
This is necessary for windows to perform correctly when writing large files.

* lukas/kernel/error_logger_warn_fix/OTP-13184: kernel: Fix progress check in error logger warn suite
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.

These error reasons can be seen in the logs after calling net_kernel:verbose(1).

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]}}}}

start_link/0 and friends are too convoluted for me.
2016-03-11Reorder and comment API functionsBjörn Gustavsson
Move all functions meant to be called from other modules before the internal functions. Comment them to make it clearer what their purpose are.

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.
2016-03-10Remove ?line macrosBjörn Gustavsson
While we are it, also re-ident the files.
2016-03-10Fix commentsBjörn Gustavsson
Remove out-commented code. Make sure that comments that are not at the end of a line starts with two '%' characters and not just one. That will become important later when we'll remove all ?line macros and ask Emacs to re-indent the files.
2016-03-10gen_tcp_misc_SUITE: Use unique node namesBjörn Gustavsson
Use unique node names to ensure that one failed test case will not cause other test cases to fail if a slave node was left.
