* RHASH_EMPTY_P: convert into an inline function卜部昌平2020-08-191-0/+1

* RHASH_TBL: is now ext-only卜部昌平2020-08-191-0/+1
| | | | | It seems almost no internal codes use RHASH_TBL any longer. Why not just eliminate it entirely, so that the macro can be purely ext-only.
* ROBJECT_IV_INDEX_TBL: convert into an inline function卜部昌平2020-08-191-0/+3
| | | | | | | Former ROBJECT_IV_INDEX_TBL macro included RCLASS_IV_INDEX_TBL, which is not disclosed to extension libraies. The macro was kind of broken. Why not just deprecate it, and convert the internal use into an inline function.
* RARRAY_AREF: convert into an inline function卜部昌平2020-08-151-0/+3
| | | | | | RARRAY_AREF has been a macro for reasons. We might not be able to change that for public APIs, but why not relax the situation internally to make it an inline function.

* add #include guard hack卜部昌平2020-04-131-13/+11
| | | | | | | | | | | | | | | | | | | | | | According to MSVC manual (*1), cl.exe can skip including a header file when that: - contains #pragma once, or - starts with #ifndef, or - starts with #if ! defined. GCC has a similar trick (*2), but it acts more stricter (e. g. there must be _no tokens_ outside of #ifndef...#endif). Sun C lacked #pragma once for a looong time. Oracle Developer Studio 12.5 finally implemented it, but we cannot assume such recent version. This changeset modifies header files so that each of them include strictly one #ifndef...#endif. I believe this is the most portable way to trigger compiler optimizations.

* move internal/debug.h definitions to internal.hKoichi Sasada2020-01-031-0/+24
| | | | Debug utilities should be accessible from any internal code.
* decouple internal.h headers卜部昌平2019-12-261-57/+45
| | | | | | | | | | | | | | | | | | Saves comitters' daily life by avoid #include-ing everything from internal.h to make each file do so instead. This would significantly speed up incremental builds. We take the following inclusion order in this changeset: 1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very first thing among everything). 2. RUBY_EXTCONF_H if any. 3. Standard C headers, sorted alphabetically. 4. Other system headers, maybe guarded by #ifdef 5. Everything else, sorted alphabetically. Exceptions are those win32-related headers, which tend not be self- containing (headers have inclusion order dependencies).
* internal/imemo.h rework卜部昌平2019-12-261-0/+2
| | | | | | Arrange contents and eliminate macros, to make them readable. Macro IFUNC_NEW was deleted because there was only one usage.
* assume C99卜部昌平2019-12-261-12/+3
| | | | | | | | | | | Now that we no longer support old compilers, we can safely delete several obsolete #ifdef gurads. Also because (as of writing) it is impossible to compile the program using C++ compilers, lets just entirely prohibit __cplusplus to reduce # of LOCs. Note however that we still cannot eliminate __STDC_VERSION__ checks, because MSVC does not define it, saying its C99 support is partial.

* re-add io.h and encoding.h into internal.h卜部昌平2019-12-261-0/+2
| | | | | | This is tentative. For the sake of simplicity we partially revert commits e9cb552ec96, ee85a6e72b and 51edb300425. Will decouple them once again when we are ready.
* split internal.h into files卜部昌平2019-12-261-2656/+53
| | | | | | | | | One day, I could not resist the way it was written. I finally started to make the code clean. This changeset is the beginning of a series of housekeeping commits. It is a simple refactoring; split internal.h into files, so that we can divide and concur in the upcoming commits. No lines of codes are either added or removed, except the obvious file headers/footers. The generated binary is identical to the one before.

* per-method serial number卜部昌平2019-12-181-2/+2
| | | | | | | | | | | | | | | | | Methods and their definitions can be allocated/deallocated on-the-fly. One pathological situation is when a method is deallocated then another one is allocated immediately after that. Address of those old/new method entries/definitions can be the same then, depending on underlying malloc/free implementation. So pointer comparison is insufficient. We have to check the contents. To do so we introduce def->method_serial, which is an integer unique to that specific method definition. PS: Note that method_serial being uintptr_t rather than rb_serial_t is intentional. This is because rb_serial_t can be bigger than a pointer on a 32bit system (rb_serial_t is at least 64bit). In order to preserve old packing of struct rb_call_cache, rb_serial_t is inappropriate.
* Skip optimized method check for most method IDsJohn Hawthorn2019-12-171-0/+1
| | | | | | | | | | | Previously every time a method was defined on a module, we would recursively walk all subclasses to see if the module was included in a class which the VM optimizes for (such as Integer#+). For most method definitions we can tell immediately that this won't be the case based on the method's name. To do this we just keep a hash with method IDs of optimized methods and if our new method isn't in that list we don't need to check subclasses at all.
* Make super in instance_eval in method in module raise TypeErrorJeremy Evans2019-12-121-0/+8
| | | | | | | | | | | | | | | | | | | | | | | This makes behavior the same as super in instance_eval in method in class. The reason this wasn't implemented before is that there is a check to determine if the self in the current context is of the expected class, and a module itself can be included in multiple classes, so it doesn't have an expected class. Implementing this requires giving iclasses knowledge of which class created them, so that super call in the module method knows the expected class for super calls. This reference is called includer, and should only be set for iclasses. Note that the approach Ruby uses in this check is not robust. If you instance_eval another object of the same class and call super, instead of an TypeError, you get super called with the instance_eval receiver instead of the method receiver. Truly fixing super would require keeping a reference to the super object (method receiver) in each frame where scope has changed, and using that instead of current self when calling super.

* use compiled binary for gem_prelude.rb.Koichi Sasada2019-12-111-3/+0
| | | | | `gem_prelude.rb` is not compiled yet. This patch compile it to compiled binary.

| | | | | Get rid of infinite recursion in expanding a load path to the real path while loading a transcoder.
* Make prepending a refined module after inclusion not break refinementsJeremy Evans2019-11-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | After the previous commit, this was still broken. The reason it was broken is that a refined module that hasn't been prepended to yet keeps the refined methods in the module's method table. When prepending, the module's method table is moved to the origin iclass, and then the refined methods are moved from the method table to a new method table in the module itself. Unfortunately, that means that if a class has included the module, prepending breaks the refinements, because when the methods are moved from the origin iclass method table to the module method table, they are removed from the method table from the iclass created when the module was included earlier. Fix this by always creating an origin class when including a module that has any refinements, even if the refinements are not currently used. I wasn't sure the best way to do that. The approach I choose was to use an object flag. The flag is set on the module when Module#refine is called, and if the flag is present when the module is included in another module or class, an origin iclass is created for the module. Fixes [Bug #13446]
* prefer class_serial over m_tbl卜部昌平2019-11-271-2/+24
| | | | | | | | | | | | | | | | | | | Decades ago, among all the data that a class has, its method table was no doubt the most frequently accessed data. Previous data structures were based on that assumption. Today that is no longer true. The most frequently accessed field moved to class_serial. That field is not always as wide as VALUE but if it is, let us swap m_tbl and class_serial.

* re-add function prototypes卜部昌平2019-11-201-0/+5
| | | | | This commit reverts a part of 0e8219f591f3f17cb7ee361e8a60dbef08145883 which broke icc. See also https://rubyci.org/logs/rubyci.s3.amazonaws.com/icc-x64/ruby-master/log/20191120T010006Z.fail.html.gz
* make functions static卜部昌平2019-11-191-18/+0
| | | | | | | These functions are used from within a compilation unit so we can make them static, for better binary size. This changeset reduces the size of generated ruby binary from 26,590,128 bytes to 26,584,472 bytes on my macihne.
* Warn on access/modify of $SAFE, and remove effects of modifying $SAFEJeremy Evans2019-11-181-5/+4
| | | | | | | | | | | | | | | | | 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2019-11-141-48/+3
| | | | | | | | | | | | 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.

* extend rb_call_cache卜部昌平2019-11-071-1/+24
| | | | | | | | | | | | | | | | | | | | | | Prior to this changeset, majority of inline cache mishits resulted into the same method entry when rb_callable_method_entry() resolves a method search. Let's not call the function at the first place on such situations. In doing so we extend the struct rb_call_cache from 44 bytes (in case of 64 bit machine) to 64 bytes, and fill the gap with secondary class serial(s). Call cache's class serials now behavies as a LRU cache.

* let the .bss section initialize static variables卜部昌平2019-11-051-2/+2
| | | | | | | | ISO/IEC 9899:1999 section 6.7.8 specifies the values of static storage which are not explicitly initialized. According to that these initializers can be omitted. Doing so improvoes future compatibility against addition / deletion of the fields of this struct.
* rb_method_basic_definition_p with CC卜部昌平2019-11-051-0/+8
| | | | | | | | | | | | | | | | | | | Noticed that rb_method_basic_definition_p is frequently called. Its callers include vm_caller_setup_args_block(), rb_hash_default_value(), rb_num_neative_int_p(), and a lot more. It seems worth caching the method resolution part. Majority of rb_method_basic_definion_p() usages take fixed class and fixed method id combinations.

* Clang can also use C call cacheJohn Hawthorn2019-10-291-1/+1
| | | | | | | | Previously this was restricted to only gcc because of the GCC_VERSION_SINCE check (which explicitly excludes clang). GCC 3.3.0 is quite old so I feel relatively safe assuming that all reasonable versions of clang support this.
* more on struct rb_call_data卜部昌平2019-10-251-10/+13
| | | | | Replacing adjacent struct rb_call_info and struct rb_call_cache into a struct rb_call_data.
* make rb_raise a GVL-only function again卜部昌平2019-10-101-0/+1
| | | | | | Requested by ko1 that ability of calling rb_raise from anywhere outside of GVL is "too much". Give up that part, move the GVL aquisition routine into gc.c, and make our new gc_raise().
* avoid overflow in integer multiplication卜部昌平2019-10-091-1/+8
| | | | | | | This changeset basically replaces `ruby_xmalloc(x * y)` into `ruby_xmalloc2(x, y)`. Some convenient functions are also provided for instance `rb_xmalloc_mul_add(x, y, z)` which allocates x * y + z byes.
* annotate malloc-ish functions卜部昌平2019-10-091-1/+6
| | | | | Make them gcc friendly. Note that realloc canot be __malloc__ attributed, according to the GCC manual.
* fix arity mismatch卜部昌平2019-10-091-1/+1
| | | | Seems nobody has actually used this macro. Such an obvious typo.
* Fix potential memory leaks by `rb_imemo_tmpbuf_auto_free_pointer`Nobuyoshi Nakada2019-10-051-2/+10
| | | | | | | | | | | | | | This function has been used wrongly always at first, "allocate a buffer then wrap it with tmpbuf". This order can cause a memory leak, as tmpbuf creation also can raise a NoMemoryError exception. The right order is "create a tmpbuf then allocate&wrap a buffer". So the argument of this function is rather harmful than just useless. TODO: * Rename this function to more proper name, as it is not used "temporary" (function local) purpose. * Allocate and wrap at once safely, like `ALLOCV`.
* Make parser_params have parent_iseq instead of base_blockYusuke Endoh2019-10-041-3/+4
| | | | | | | | | | | | The parser needs to determine whether a local varaiable is defined or not in outer scope. For the sake, "base_block" field has kept the outer block. However, the whole block was actually unneeded; the parser used only base_block->iseq. So, this change lets parser_params have the iseq directly, instead of the whole block.
* Revert https://github.com/ruby/ruby/pull/2486卜部昌平2019-10-031-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commits: 10d6a3aca7 8ba48c1b85 fba8627dc1 dd883de5ba 6c6a25feca 167e6b48f1 7cb96d41a5 3207979278 595b3c4fdd 1521f7cf89 c11c5e69ac cf33608203 3632a812c0 f56506be0d 86427a3219 . The reason for the revert is that we observe ABA problem around inline method cache. When a cache misshits, we search for a method entry. And if the entry is identical to what was cached before, we reuse the cache. But the commits we are reverting here introduced situations where a method entry is freed, then the identical memory region is used for another method entry. An inline method cache cannot detect that ABA. Here is a code that reproduce such situation: ```ruby require 'prime' class << Integer alias org_sqrt sqrt def sqrt(n) raise end GC.stress = true Prime.each(7*37){} rescue nil # <- Here we populate CC class << Object.new; end # These adjacent remove-then-alias maneuver # frees a method entry, then immediately # reuses it for another. remove_method :sqrt alias sqrt org_sqrt end Prime.each(7*37).to_a # <- SEGV ```
