2016-01-27Simplify starting of code serverBjörn Gustavsson
There is unnecessary knowledge about the -nostick option in the 'kernel' module. -nostick can be handled entirely in the 'code' module. There is no need to have both code:start_link/0 and code:start_link/1. code:start_link/0 is sufficient. Also get rid of error handling for things that cannot happen: The 'init' module has made sure that init:get_argument(root) can't fail, so there is no need for any error-reporting code. (See e1dc0aa4.) We also don't need to test the return value from code_server:start_link/1, because it will always return {ok,Pid} (or crash).
2016-01-27Remove first argument of code_server:call()Björn Gustavsson
Remove the first argument for code_server:call(). It makes no sense. The only caller is 'code'. Note that the code_server module is undocumented and that code_server:call() is an internal helper function.
2016-01-22Remove redundant test that hipe_unified_loader is loadedBjörn Gustavsson
For some reason, there is a test in code_server that hipe_unified_loader is loaded before trying to call it. The test was added in R9B, but it is not clear why. Before starting the code server, the 'code' module would always load hipe_unified_loader; thus there is now way that the test can ever fail.

2016-01-22code_server: Tighten type of modules parametersBjörn Gustavsson
The following functions in the 'code' module only allow the module argument to an atom: load_file/1 load_binary/3 ensure_loaded/1 delete/1 purge/1 soft_purge/1 get_object_code/1 Therefore, there is no reason that the corresponding implementation in code_server should allow the module to be either an atom or a string. Only accept an atom and remove the helper functions to_atom/1 and do_mod_call/4.
2016-01-13erts: Refactor code:purge/1 and code:soft_purge/1Sverker Eriksson
by moving code from code_server to erts_code_purger. This is more or less a copy-paste from code_server.erl to erts_code_purger.erl. All the inner mechanics of code:purge/1 and code:soft_purge/1 are unchanged.

2015-12-15kernel: Remove cmd server for unix os:cmdLukas Larsson
Since we no longer to vfork in the emulator there is no need to serialize the os:cmd calls through a central command server. This greatly decreases the complexity of this code and should make it fast+more scalable. OTP-13089
2015-12-14Remove the code path cache in the code serverBjörn Gustavsson
In practice, it does not seem that code path cache can improve performance. Looking for any file that is not found will cause the cache to be rebuilt, which will negate any gain of using the cache.

* maint: Avoid always updating inet_dns in the primary bootstrap
2015-10-05Avoid always updating inet_dns in the primary bootstrapBjörn Gustavsson
The include file inet_dns_record_adts.hrl is generated by the Perl script inet_dns_record_adts.pl in a non-deterministic way. That is, every time the script is run, the functions will be in a different order. That will cause inet_dns.beam in the primary bootstrap to be updated every time the bootstrap is updated, even though there is no actual code change. Modify the Perl script to sort the keys pulled out from hashes to make the order deterministic.

2015-06-09Add 'show_econnreset' TCP socket optionRory Byrne
An ECONNRESET is a socket error which tells us that a TCP peer has sent an RST. The RST indicates that they have aborted the connection and that the payload we have received should not be considered complete. Up until now, the implementation of TCP in inet_drv.c has hidden the receipt of the RST from the user, treating it as though it was just a FIN terminating the read side of the socket. There are many cases where user code needs to be able to distinguish between a socket that was closed normally and one that was aborted. Setting the option {show_econnreset, true} enables the user to receive ECONNRESET errors on both active and passive sockets. A connected socket returned from gen_tcp:accept/1 will inherit the show_econnreset setting of the listening socket. By default this option is set to {show_econnreset, false}. Note that this patch only enables the reporting of ECONNRESET when the socket is being read from. It does not report ECONNRESET (or EPIPE) when the user tries to write to a connection when an RST has already been received. Currently the TCP implementation in inet_drv.c hides all such send errors from the user in favour of returning {error, close}. A separate patch will be needed to enable the reporting of such errors.

2015-06-04Move architecture knowledge out of hipe loaderRichard Carlsson
Make code_server be responsible for finding the architecture and deciding whether to try to load native code, in order to avoid repeated calls to system_info(hipe_architecture) and clumsy uses of try/catch to test if hipe is enabled.
