* maint: Update documentation for code-loading functions code: Correct the types for error returns Eliminate run-time system crash in code:load_abs/1
2016-01-28code: Correct the types for error returnsBjörn Gustavsson
The specifications for functions that load code in the 'code' module (e.g. code:load_file/1) have some problems: * The specs claim that the functions can return {error,on_load}, but they never do. However, they can return {error,on_load_failure} if the -on_load function in a module fails. * The specs claim that the functions can return {error,native_code}, but they never do. While we are it, also extend the on_load_errors/1 test case to test that the load functions return {error,on_load_failure} when an -on_load function fails.
2016-01-27code_server: Add types to the state recordBjörn Gustavsson
2016-01-27code_server: Don't export internal system_* functionsBjörn Gustavsson
There is no reason to export system_continue/3 and system_terminate/4 from code_server. Servers that use proc_lib and 'sys' to handle system message do need those functions exported, but code_server contains a modified copy of the system message handling code from 'sys', and that code only make local calls to system_continue/3 and system_terminate/4.
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.
2016-01-25Eliminate run-time system crash in code:load_abs/1Björn Gustavsson
The run-time system would terminate if code:load_abs/1 was called with a filename containing any non-latin1 characters. The reason is that code_server would attempt to construct a module name from the filename using list_to_atom/1 and that atoms currently are limited to the latin1 character set. But how should the error be reported? I have decided to that the simplest and least confusing way is to move the call to list_to_atom/1 to 'code' module and let it crash the calling process. The resulting stack back trace will make it clear what the reason for the crash was.
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.
2016-01-22Avoid testing for pending on_load twiceBjörn Gustavsson
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.
2016-01-20Introduce time warp safe trace timestamp formatsRickard Green
New timestamp options for trace, sequential trace, and system profile: - monotonic_timestamp - strict_monotonic_timestamp
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.
