2016-02-25Simplify and robustify code_server:all_loaded/1Björn Gustavsson
The main ets table kept by code_server contains several pieces of information. Therefore, code_server:all_loaded/1 need to filter the information in the table. code_server:all_loaded/1 can be simplified if we use ets:select/2. Currently, the filtering is done by filtering away unwanted stuff ({sticky_dir,Mod} tuples). It is more robust to filter on the stuff that we want to keep ({Mod,Path} tuples, where Mod is an atom) in case that we'll add more auxiliary records to the table later.
2016-02-25Add erl_prim_loader:get_modules/3Björn Gustavsson
When we are going to implement functions that can load many modules at once, we don't the erl_prim_loader server to become a bottleneck. Therefore, we need erl_prim_loader:get_modules/3 that can read many BEAM files in parallel. Note that we will not bother making reading from archive files or using the inet loader efficient. That can be done later if it turns out to be important.

2016-02-17Remove test_server as a standalone applicationBjörn Gustavsson
The test_server application has previously been deprecated. In OTP 19, we will move relevant parts of test_server into the common_test application. Test suites that include test_server.hrl must be updated to include ct.hrl instead. Test suites that include test_server_line.hrl must removed that inclusion. Test suites that call the test_server module directly will continue to work in OTP 19. The test suites for Erlang/OTP are built and executed in exactly the same way as previously. Here are some more details. The modules test_server*.erl and erl2html2.erl in lib/test_server/src have been moved to common_test/src. The test_server.hrl and test_server_line.hrl include files have been deleted. The macros in test_server.hrl have been copied into lib/common_test/include/ct.hrl. The ts*.erl modules and their associated data files in lib/test_server/src has been been moved to the new directory lib/common_test/test_server. The ts* modules are no longer built to lib/common_test/ebin. They will only built when 'make release_tests' is executed. The test suite for test_server has been moved to lib/common_test/test. The rest of the files have been deleted.
2016-02-17Remove out-commented references to the test_server applicationsBjörn Gustavsson
Cleanliness.
2016-02-17Makefiles: Remove test_server from include path and code pathBjörn Gustavsson
Since no test suites includede test_server.hrl, there is no need to have test_server in the include path or code path.
2016-02-17Eliminate use of test_server.hrl and test_server_line.hrlBjörn Gustavsson
As a first step to removing the test_server application as as its own separate application, change the inclusion of test_server.hrl to an inclusion of ct.hrl and remove the inclusion of test_server_line.hrl.

2016-02-15Prettify default error_logger output somewhatMagnus Henoch
The default error logger, the one in use before a more sophisticated error logger can be installed, has rather terse output, in part because it cannot rely on io:format. This patch attempts to improve the error logger within that constraint: - Print timestamps as YYYY-MM-DD HH:MM:SS - For error reports with format strings, just print the format string and the format arguments on separate lines - For error reports with tuple lists, print each pair on a separate line
2016-02-11erl_prim_loader_SUITE: Refactor helper functionsBjörn Gustavsson
Eliminate duplicated code by factoring out the common code for starting erl_boot_server and a slave node. Also, in the new start_boot_server/0 helper, fix a problem with Linux systems that assign 127.0.1.1 as the IP address for the hostname. Also stop using the -setcookie option when starting a node using -loader inet. The inet loading method doesn't use the distribution anymore.

The perf_counter is a very very cheap and high resolution timer that can be used to timestamp system events. It does not have monoticity guarantees, but should on most OS's expose a monotonous time. A special instruction has been created for this counter to further speed up fetching it. OTP-12908

* maint: Update documentation for code-loading functions code: Correct the types for error returns Eliminate run-time system crash in code:load_abs/1
2016-01-28Update documentation for code-loading functionsBjörn Gustavsson
Some of the error reasons were not explained.
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.
2016-01-20erl_prim_loader: Rename release_archives/0Björn Gustavsson
Rename release_archives/0 to purge_archive_cache/0 to make it clearer what it does and what it doesn't do. Also add a comment about its intended purpose. Note that release_archives/0 is not documented and is part of the experimental archive feature. Furthermore, the only uses I could find were in the test suite. I did not find any uses in the external applications relx and rebar3 applications that are known to use archives. Therefore, I think that the increased clarity is worth the small risk of breaking code.
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: Make erlang:purge_module/1 safeSverker Eriksson
Problem: erlang:purge_module/1 is not safe in the sense that very bad things may happen if the code to be purged is still referred to by live processes. Introduce erts_internal:purge_module which is the same as the old erlang:purge_module BIF (except it returns false if no such old module). Implement erlang:purge_module in Erlang and let it invoke erts_code_purger for safe purging where all clogging processes first are killed.
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.
