lua/testes/utf8.lua, branch v5.4.9

More control over encoding of test files

2023-08-17T13:42:56+00:00

The few UTF-8 test files are commented as such, and there is only one non UTF-8 test file (to test non UTF-8 sources).

Avoid excessive name pollution in test files

2022-12-28T21:34:11+00:00

Test files are more polite regarding the use of globals when locals would do, and when globals are necessary deleting them after use.

Bug: 'utf8.codes' accepts spurious continuation bytes

2022-09-23T13:41:16+00:00

Avoid overflows when incrementing parameters in C

2021-09-22T16:10:39+00:00

Any C function can receive maxinteger as an integer argument, and therefore cannot increment it without some care (e.g., doing unsigned arithmetic as the core does).

Details (more uniformity in error messages)

Added macro 'luaL_pushfail'

2019-08-16T17:58:02+00:00

The macro 'luaL_pushfail' documents all places in the standard libraries that return nil to signal some kind of failure. It is defined as 'lua_pushnil'. The manual also got a notation (@fail) to document those returns. The tests were changed to be agnostic regarding whether 'fail' is 'nil' or 'false'.

Fixed wrong error message in 'return math.seed(0)'

2019-04-04T19:31:24+00:00

Bug introduced in commit 28d829c8: OP_TAILCALL might raise an error without saving 'pc'. (This commit also fixes a detail in 'testes/uf8.lua'.)

Small optimizations in range checks

2019-03-27T17:56:10+00:00

Checks of the form '1 <= x && x <= M' were rewritten in the form '(unsigned)x - 1 < (unsigned)M', which is usually more efficient. (Other similar checks have similar translations.) Although some compilers do these optimizations, that does not happen for all compilers or all cases.

Changes in the validation of UTF-8

2019-03-15T16:14:17+00:00

All UTF-8 encoding functionality (including the escape sequence '\u') accepts all values from the original UTF-8 specification (with sequences of up to six bytes). By default, the decoding functions in the UTF-8 library do not accept invalid Unicode code points, such as surrogates. A new parameter 'nonstrict' makes them accept all code points up to (2^31)-1, as in the original UTF-8 specification.

Added directory to test file names in '$Id:'

2018-07-25T18:31:04+00:00

From the point of view of 'git', all names are relative to the root directory of the project. So, file names in '$Id:' also should be relative to that directory: the proper name for test file 'all.lua' is 'testes/all.lua'.
