* rickard/null-chars/ERL-370/OTP-14543: Don't allow null chars in various strings Conflicts: erts/emulator/beam/erl_alloc.types erts/preloaded/ebin/erlang.beam
2017-10-11Don't allow null chars in various stringsRickard Green
Various places that now reject null chars inside strings - Primitive file operations reject it in filenames. - Primitive environment variable operations reject it in names and values. - os:cmd() reject it in its input. Also '=' characters are rejected by primitive environment variable operations in environment variable names. Documentation has been updated to document null characters in these types of data as invalid. Currently these operations accept null chars at the end of strings, but that will change in the future.

2017-02-17Teach make_preload to handle the new 'AtU8' chunkBjörn Gustavsson
26b59dfe67 introduced the new 'AtU8' chunk to support Unicode atoms. make_preload strips the pre-loaded BEAM files so that they only contain essential chunks. It expects to find the old 'Atom' chunk. Teach make_preload to read the new 'AtU8' chunk instead of the old chunk. Also produce a nice error message if someone by mistake compiles the pre-loaded modules with an OTP 19 compiler.

2016-09-05Implement the new ceil/1 and floor/1 guard BIFsBjörn Gustavsson
Implement as ceil/1 and floor/1 as new guard BIFs (essentially part of Erlang language). They are guard BIFs because trunc/1 is a guard BIF. It would be strange to have trunc/1 as a part of the language, but not ceil/1 and floor/1.

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.

2016-01-13erts: 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.
