2017-10-27Correct erlang:is_builtin/3 for apply/2 and yield/0Björn Gustavsson
erlang:is_builtin(erlang, M, F) returns false for apply/2 and yield/0. The documentation for erlang:is_builtin/3 says that it returns true for BIFs that are implemented in C. apply/2 and yield/0 are implemented in C (as BEAM instructions), and therefore the correct return value is true. Also see a similar argument that was made for apply/3 in the past: http://erlang.org/pipermail/erlang-bugs/2015-October/005101.html https://bugs.erlang.org/browse/ERL-500

such as a sub-binary, of a correct utf8 string, that ends in the middle of a character.

2017-01-30Add new AtU8 beam chunkJosé Valim
The new chunk stores atoms encoded in UTF-8. beam_lib has also been modified to handle the new 'utf8_atoms' attribute while the 'atoms' attribute may be a missing chunk from now on. The binary_to_atom/2 BIF can now encode any utf8 binary with up to 255 characters. The list_to_atom/1 BIF can now accept codepoints higher than 255 with up to 255 characters (thanks to Björn Gustavsson).

2016-05-30Reintroduce erlang:halt/0/1 in erl_bif_types.erlSverker Eriksson
Removed in f9cb80861f169743 when changed impl from C to Erlang. But seems they are needed to keep dialyzer tests happy. Also improved bif_SUITE:shadow_comments to include all exported in module erlang, not just the "snifs". ...which detected that apply/2 was missing Shadowed comment as well.

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.
2015-10-09Teach erlang:is_builtin/3 that erlang:apply/3 is built-inBjörn Gustavsson
erlang:is_builtin(erlang, apply, 3) returns 'false'. That seems to be an oversight in the implementation of erlang:is_builtin/3 rather than a conscious design decision. Part of apply/3 is implemented in C (as a special instruction), and part of it in Erlang (only used if apply/3 is used recursively). That makes apply/3 special compared to all other BIFs. From the viewpoint of the user, apply/3 is a built-in function, since it cannot possibly be implemented in pure Erlang. Noticed-by: Stavros Aronis

This commit improves crash dumps in several ways: * Suspends schedulers to get a current snapshot * Dumps information about scheduler * Dumps stack trace of current running process (including Garbing processes)

2013-11-09Add os:unsetenv/1Martin Hässler
New BIF os:unsetenv/1 which deletes an environment variable and returns 'true'. Does not change any old functionality. Calls the libc function unsetenv(3) on UNIX and SetEnvironmentVariableW(key, NULL) on Windows. The unicode support is the same as for os:getenv and os:putenv.

2012-02-08bif_SUITE: Add test to ensure that all guard BIFs have type infoBjörn Gustavsson
2012-02-08Replace autoimport_SUITE with bif_SUITE:auto_imports/1Björn Gustavsson
erts/test/autoimport_SUITE tested that auto-import information in erl_internal:bif/2 was consistent with the documentation. It did it by scanning erlang.xml. Since the documentation is now based on the specs in erlang.erl, we should now test consistency of the specs and erl_internal:bif/2. Since anyone that adds a new BIF runs the emulator test suite, it makes sense to do this test in bif_SUITE in the emulator test suite.
2012-02-08bif_SUITE: Add test case for specs and BIF stubsBjörn Gustavsson
Rename the existing types/1 test case to erl_bif_types/1 to make it clearer what it does. Also no longer test for missing type information for BIFs (since it has become optional), but only check that the information provided seems to be consistent. Introduce the specs/1 test case to ensure that all BIFs have specs. Also introduce improper_bif_stubs/1 to check for proper stubs. Since the BEAM loader will now silently allow stubs for BIFs, we want to be particular about exactly what a stub look like, so that an Erlang function is not unintentionally overridden by a BIF.

2010-06-03Merge branch 'pan/otp_8579_autoimport_override' into devErlang/OTP
* origin/pan/otp_8579_autoimport_override: Update preloaded modules Update primary bootstrap Remove outcommented code from erl_lint Make port_command/3 auto-imported Remove (harmless) warnings about min/max in core applications Autoimport min/2 and max/2 Improve coverage of erl_int in testcases Change warning to error for nowarn_bif_clash compiler directive Add -compile({no_auto_import,[F/A]}) doc to compiler.xml Add some testcases to compiler to verify that overriding really happens Return nowarn_bif_clash functionality but with warning Teach erl_lint to better override BIFs with local functions and imports Teach compiler to override autoimport with import First prototype for local functions overriding autoimported OTP-8579 Local functions should override auto-imported Local and imported functions now override the autoimported BIFs when the names clash. The pre R14 behaviour was that autoimported BIFs would override local functions. To avoid that old programs change behaviour, the following will generate an error: Doing a call without explicit module name to a local function having a name clashing with the name of an autoimported BIF that was present (and autoimported) before OTP R14A Explicitly importing a function having a name clashing with the name of an autoimported BIF that was present (and autoimported) before OTP R14A Using any form of the old compiler directive nowarn_bif_clash If the BIF was added or autoimported in OTP R14A or later, overriding it with an import or a local function will only result in a warning, To resolve clashes, you can either use the explicit module name erlang to call the BIF, or you can remove the autoimport of that specific BIF by using the new compiler directive -compile({no_auto_import,[F/A]})., which makes all calls to the local or imported function without explicit module name pass without warnings or errors. The change makes it possible to add autoimported BIFs without breaking or silently changing old code in the future. However some current code ingeniously utilizing the old behaviour or the nowarn_bif_clash compiler directive, might need changing to be accepted by the compiler.
