2020-10-15Fix out of bound access in `parse.y`.Yukihiro "Matz" Matsumoto
2020-10-12Remove the length of `Float' pool from the binary dump.Yukihiro "Matz" Matsumoto
Also fixed the size calculation of `irep` dump, that could cause memory corruption.
2020-10-12Dump/load 16 bits for `ilen` and `slen` in `irep`.Yukihiro "Matz" Matsumoto
Those types are `uint16_t` in definition. Also we no longer need padding for `iseq`.
2020-10-12Don't compare `int' with `size_t` (from `sizeof()`).Yukihiro "Matz" Matsumoto
2020-10-12Change float representation in `mrb` binary files.Yukihiro "Matz" Matsumoto
From human readable (ASCII) string representation to binary dump of IEEE754 in little endian.
2020-10-12Raname `mrb_exc_new_str_lit()` to `mrb_exc_new_lit()`.Yukihiro "Matz" Matsumoto
It uses `mrb_str_new_lit()` internally, but it doesn't need to express it in the name of the function (macro).
2020-10-12Rename float configuration option names.Yukihiro "Matz" Matsumoto
- `MRB_WITHOUT_FLOAT` => `MRB_NO_FLOAT` - `MRB_USE_FLOAT` => `MRB_USE_FLOAT32` The former is to use `USE_XXX` naming convention. The latter is to make sure `float` is 32bit float and not floating point number in general.
2020-10-12Fix typo `_hander` -> `_handler`.Yukihiro "Matz" Matsumoto
2020-10-12Extended mruby binary formatdearblue
The catch handler table is combined with iseq block. This is to prevent the structure from growing by adding a field for the catch handler table to the `mrb_irep` structure. "iseq block" and "catch handler table": [number of catch handler table (2 bytes)] [number of byte code (4 bytes)] [iseq (any bytes)] [catch handlers (multiple of 7 bytes)] catch handler: [catch type (1 byte)] [begin offset (2 bytes)] [end offset (2 bytes)] [target offset (2 bytes)] catch type: enum mrb_catch_type (0 = rescue, 1 = ensure) begin offset: Includes the specified instruction address end offset: Does not include the specified instruction address target offset: replaces pc with the specified instruction address This table is not expanded by `read_irep_record_1()`. The necessary elements are expanded one by one when used.
2020-10-12You don't need to keep index in local variables info in `irep`.Yukihiro "Matz" Matsumoto
2020-10-12Split `MRB_BINARY_FORMAT` to major and minor.Yukihiro "Matz" Matsumoto
The minor versions should be upper compatible. So mere opcode, section addition can be done without breaking compiled binary.
2020-10-12Use `int` instead of `mrb_int` for arena index.Yukihiro "Matz" Matsumoto
2020-10-12Add casts to silence warnings.Yukihiro "Matz" Matsumoto
2020-10-12Clarify the use of `MRB_64BIT` and `MRB_INT64` in `dump.c` and `load.c`.Yukihiro "Matz" Matsumoto
- `MRB_64BIT`: the size of a pointer is 64 bits - `MRB_INT64`: the size of `mrb_int` is 64 bits
2020-10-12Generate C struct from `irep` instead of binary dump.Yukihiro "Matz" Matsumoto
2020-10-12Replace entire `irep->pool`.Yukihiro "Matz" Matsumoto
Changes: - `pool format is completely replaced - supported types: `STR`, `INT32`, `INT64`, `FLOAT` - `FLOAT` may be replaced by binary representation in the future - insert `NUL` after string literals in `mrb` files - `irep->pool` no longer store values in `mrb_value` - instead it stores in `mrb_pool_value` - less allocation - `mrb_irep` can be stored in ROM
2020-10-12Rename `struct mrb_locals` to `struct mrb_lvinfo`.Yukihiro "Matz" Matsumoto
That stands for "local variable information".
2020-10-12Constify `irep` members.Yukihiro "Matz" Matsumoto
- `pool` - `syms` - `reps`
2020-08-11Fix `mrb_int` and `size_t` combination warnings.Yukihiro "Matz" Matsumoto
2020-06-05Change arena index from `mrb_int` to `int`.Yukihiro "Matz" Matsumoto

If occurs `NoMemoryError` exception in second `malloc()`, first `malloc()` pointer is not freed. commit fef1c152ce4e52b9e4a34dc23aca5b02907ac639 Author: dearblue <[email protected]> Date: Sat Jan 19 13:05:09 2019 +0900 Fix stack overflow when out of memory As a result of this change, no backtrace information is set for NoMemoryError (`mrb->nomem_err`). Detailes: When generating a backtrace, called `mrb_intern_lit()`, `mrb_str_new_cstr()` and `mrb_obj_iv_set()` function with `exc_debug_info()` function in `src/error.c`. If a `NoMemoryError` exception occurs at this time, the `exc_debug_info()` function will be called again, and in the same way `NoMemoryError` exception raised will result in an infinite loop to occurs stack overflow (and SIGSEGV). commit da7d7f881bbbad9988a3a2b7bad8f2b72ff06bc6 Author: dearblue <[email protected]> Date: Sun Jan 20 12:00:38 2019 +0900 Fix NULL pointer dereference `mrb->nomem_err` when not initialized Add internal functions (not `static`): * `mrb_raise_nomemory()` * `mrb_core_init_abort()`
2020-05-07Remove endian information/flags from compiled binary format.Yukihiro "Matz" Matsumoto
Since `mruby 2.0`, compiled bytecode no longer depends on the endian of the machine.
2020-01-06Refactor `mrb_cstr_to_dbl`; ref #4920Yukihiro "Matz" Matsumoto
2020-01-06Avoid creating temporary objects in `read_irep_record_1`; close #4920Yukihiro "Matz" Matsumoto
The basic idea of this change is from @dearblue. Note: the arguments of `mrb_str_pool()` have changed, but the function is provided for internal use (No `MRB_API`). So basically you don't have to worry about the change.
2019-09-21Rename MRB_USE_ETEXT_EDATA to MRB_USE_LINK_TIME_RO_DATA_P and support lld ↵Fangrui Song
linked programs In lld linked programs, .rodata comes before .text, thus mrb_ro_data_p will return false for strings in .rodata. Change the lower bound from _etext to __ehdr_start to catch these cases. This works for ld.bfd, gold and lld, and it does not have false positives even if .init_array does not exist. Remove the branch that uses _edata: strings in .data can be modified so this is semantically incorrect. Delete the __APPLE__ branch (its manpages say get_etext() and get_edata() are strongly discouraged). .init_array has been adopted by most ELF platforms to supersede .ctors. Neither _etext nor _edata is used, so rename MRB_USE_ETEXT_EDATA to MRB_USE_EHDR_START.

2019-04-01Avoid keeping pointers from `mrb_sym2name_len()`; fix #4342Yukihiro "Matz" Matsumoto
The addresses for packed inline symbols reference `mrb->symbuf` that could be overridden by the later call of `mrb_sym2name_len`. Since file names in call stack information are kept as symbols, keeping the address in the C structures could cause problems like #4342. This changes small incompatible changes in function prototypes: * `mrb_parser_get_filename`: return value changed to `mrb_sym`. * `mrb_debug_get_filename`: add `mrb_state*` as a first argument. * `mrb_debug_get_line`: ditto. I believe above functions are almost internal, and no third-party mrbgem use them.
2019-01-08Fix dump/load float leteral evaluate to infinityKOBAYASHI Shuji
Example: # example.rb p(2e308) p(-2e308) Good: $ bin/mruby example.rb inf -inf Bad: $ bin/mrbc example.rb $ bin/mruby -b example.mrb 0 -0 Cause: Float infinity representation is `inf` on dump and it is converted by corresponding `String#to_f` on load. Treatment: - Introduce new representations (`i`: +infinity, `I`: -infinity) - Allow old representations (`inf`, `-inf`, `infinity`, `-infinity`) too - Raise error for unknown representations (use corresponding `Kernel#Float`)

2016-09-25Remove needless MRB_APIKouhei Sutou
ref #3215 If a function (such as mrb_read_irep_file()) is declared without MRB_API in header file (such as include/mruby/dump.h), implementation of the function in source file (such as src/load.c) should also defined without MRB_API. If MRB_API is mismatch, Visual C++ reports link error with C2375 error code: https://msdn.microsoft.com/en-us/library/5k6kw95a.aspx

2015-12-29Support backtrace after method callsKouhei Sutou
GitHub: fix #2902, #2917 The current implementation traverses stack to retrieve backtrace. But stack will be changed when some operations are occurred. It means that backtrace may be broken after some operations. This change (1) saves the minimum information to retrieve backtrace when exception is raised and (2) restores backtrace from the minimum information when backtrace is needed. It reduces overhead for creating backtrace Ruby objects. The space for the minimum information is reused by multiple exceptions. So memory allocation isn't occurred for each exception.
