* Warn on access/modify of $SAFE, and remove effects of modifying $SAFEJeremy Evans2019-11-181-5/+0
| | | | | | | | | | | | | | | | | This removes the security features added by $SAFE = 1, and warns for access or modification of $SAFE from Ruby-level, as well as warning when calling all public C functions related to $SAFE. This modifies some internal functions that took a safe level argument to no longer take the argument. rb_require_safe now warns, rb_require_string has been added as a version that takes a VALUE and does not warn. One public C function that still takes a safe level argument and that this doesn't warn for is rb_eval_cmd. We may want to consider adding an alternative method that does not take a safe level argument, and warn for rb_eval_cmd.

* Revert "introduce debug check."Koichi Sasada2019-09-301-11/+0
| | | | | | This reverts commit c3b84f2de83a27acc638f99743bfa2c44bac621c. Backtrace shows it is before running tests and debug check was nonsense.
* introduce debug check.Koichi Sasada2019-09-301-0/+11
| | | | | | | | | | There are random failures: > lib/rubygems/core_ext/kernel_require.rb:61:in `require': > wrong number of arguments (given 1, expected 0) (ArgumentError) http://ci.rvm.jp/results/trunk-jemalloc@silicon-docker/2275159 To check this failure, I added a small check code.
