* Deprecate taint/trust and related methods, and make the methods no-opsJeremy Evans2019-11-181-8/+0
| | | | | | This removes the related tests, and puts the related specs behind version guards. This affects all code in lib, including some libraries that may want to support older versions of Ruby.
* Warn on access/modify of $SAFE, and remove effects of modifying $SAFEJeremy Evans2019-11-181-3/+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.
* delete unused functions卜部昌平2019-11-141-16/+0
| | | | | | | | | | | | Looking at the list of symbols inside of libruby-static.a, I found hundreds of functions that are defined, but used from nowhere. There can be reasons for each of them (e.g. some functions are specific to some platform, some are useful when debugging, etc). However it seems the functions deleted here exist for no reason. This changeset reduces the size of ruby binary from 26,671,456 bytes to 26,592,864 bytes on my machine.

* Define IO#read/write_nonblock with builtins.Koichi Sasada2019-11-081-6/+11
| | | | | | | IO#read/write_nonblock methods are defined in prelude.rb with special private method __read/write_nonblock to reduce keyword parameters overhead. We can move them into io.rb with builtin functions.
* io.c (rb_update_max_fd): fail with a negative file descripterYusuke Endoh2019-10-131-1/+1
| | | | | | Coverity Scan points out that ext/socket/unixsocket.c may pass -1 to rb_update_max_fd. I'm unsure whether it can happen actually or not, but it would be good for the function to reject a negative value.
* io.c (NUM2IOCTLREQ): Accept a value more than INT_MAXYusuke Endoh2019-10-111-1/+1
| | | | | | | | ioctl accepts int as request arguments on some platforms, but some requests are more than INT_MAX, e.g., RNDGETENTCNT(0x80045200). Passing (0x80045200 | (-1 << 32)) may work around the issue, but it may not work on a platform where ioctl accepts unsigned long. So this change uses NUM2LONG and then casts it to int.
* Make rb_scan_args handle keywords more similar to Ruby methods (#2460)Jeremy Evans2019-09-251-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Cfuncs that use rb_scan_args with the : entry suffer similar keyword argument separation issues that Ruby methods suffer if the cfuncs accept optional or variable arguments. This makes the following changes to : handling. * Treats as **kw, prompting keyword argument separation warnings if called with a positional hash. * Do not look for an option hash if empty keywords are provided. For backwards compatibility, treat an empty keyword splat as a empty mandatory positional hash argument, but emit a a warning, as this behavior will be removed in Ruby 3. The argument number check needs to be moved lower so it can correctly handle an empty positional argument being added. * If the last argument is nil and it is necessary to treat it as an option hash in order to make sure all arguments are processed, continue to treat the last argument as the option hash. Emit a warning in this case, as this behavior will be removed in Ruby 3. * If splitting the keyword hash into two hashes, issue a warning, as we will not be splitting hashes in Ruby 3. * If the keyword argument is required to fill a mandatory positional argument, continue to do so, but emit a warning as this behavior will be going away in Ruby 3. * If keyword arguments are provided and the last argument is not a hash, that indicates something wrong. This can happen if a cfunc is calling rb_scan_args multiple times, and providing arguments that were not passed to it from Ruby. Callers need to switch to the new rb_scan_args_kw function, which allows passing of whether keywords were provided. This commit fixes all warnings caused by the changes above. It switches some function calls to *_kw versions with appropriate kw_splat flags. If delegating arguments, RB_PASS_CALLED_KEYWORDS is used. If creating new arguments, RB_PASS_KEYWORDS is used if the last argument is a hash to be treated as keywords. In open_key_args in io.c, use rb_scan_args_kw. In this case, the arguments provided come from another C function, not Ruby. The last argument may or may not be a hash, so we can't set keyword argument mode. However, if it is a hash, we don't want to warn when treating it as keywords. In Ruby files, make sure to appropriately use keyword splats or literal keywords when calling Cfuncs that now issue keyword argument separation warnings through rb_scan_args. Also, make sure not to pass nil in place of an option hash. Work around Kernel#warn warnings due to problems in the Rubygems override of the method. There is an open pull request to fix these issues in Rubygems, but part of the Rubygems tests for their override fail on ruby-head due to rb_scan_args not recognizing empty keyword splats, which this commit fixes. Implementation wise, adding rb_scan_args_kw is kind of a pain, because rb_scan_args takes a variable number of arguments. In order to not duplicate all the code, the function internals need to be split into two functions taking a va_list, and to avoid passing in a ton of arguments, a single struct argument is used to handle the variables previously local to the function.

* drop-in type check for rb_define_singleton_method卜部昌平2019-08-291-1/+1
| | | | | | We can check the function pointer passed to rb_define_singleton_method like how we do so in rb_define_method. Doing so revealed many arity mismatches.
* drop-in type check for rb_define_global_function卜部昌平2019-08-291-4/+4
| | | | | | We can check the function pointer passed to rb_define_global_function like we do so in rb_define_method. It turns out that almost anybody is misunderstanding the API.
* delete `$` sign from C identifiers卜部昌平2019-08-271-3/+3

* rb_define_hooked_variable now free from ANYARGS卜部昌平2019-08-271-1/+13
| | | | | | | | | After 5e86b005c0f2ef30df2f9906c7e2f3abefe286a2, I now think ANYARGS is dangerous and should be extinct. This commit uses rb_gvar_getter_t / rb_gvar_setter_t for rb_define_hooked_variable / rb_define_virtual_variable which revealed lots of function prototype inconsistencies. Some of them were literally decades old, going back to dda5dc00cff334cac373096d444a0fd59e716124.

* io.c: make ioctl_req_t int in AndroidYusuke Endoh2019-08-201-1/+1
| | | | | | The second argument of ioctl seems to be int in Android. Android is not a supported platform, but this one-line change allows ruby to build by Android NDK r20.

* Do not change IO.pipe encodings if encodings explicitly givenJeremy Evans2019-07-301-1/+1
| | | | | | | | This commit makes it so that if the binmode option is given with any encoding arguments, the reader and writer IO objects are not set to binary encoding. Fixes [Bug #12989]
* Passing `binmode: true` to `IO.pipe` should behave like `binmode`Aaron Patterson2019-07-301-0/+6
| | | | | | | | | | | When passing `binmode: true` to `IO.pipe`, it should behave the same way as calling `binmode` on each of the file handles. It should set the file to binmode *and* set the encoding to binary on the file. Before this commit, passing `binmode: true` to `IO.pipe` would make `binmode?` return `true`, but the file's encoding would remain the same as the default encoding. Passing `binmode: true` should make `binmode?` return `true` *and* set the encoding to binary.
