Fix bug #72093: bcpowmod accepts negative scale and corrupts _one_ definition We can not modify result since it can be copy of _zero_ or _one_, etc. and "copy" in bcmath is just bumping the refcount.
2016-04-25 01:33:32 +00:00
--TEST--
Ensure bcmath scale is between 0 and INT_MAX Make sure bcmatch scale is between 0 and INT_MAX, both for the ini setting, and all the functions accepting a scale argument. A ValueError is thrown if a function argument is out of range. Closes GH-5455.

bcpowmod(): Argument #4 ($scale) must be between 0 and 2147483647
Fixed bug #75169 (BCMath errors/warnings bypass error handling) Instead of writing warning messages to `stderr`, we employ PHP's error handling to raise `E_WARNING` even for the single case where `bc_rt_error()` has been called, since that did not actually error out. We choose to call `php_error_docref()` directly in libbcmath, since there is no upstream, and since other PHP core functionality is already used in our bundled libbcmath. Accordingly, we remove `rt.c` so it will not be accidentally used in the future. Besides adapting a few existing tests, we add new tests so that the warnings are tested at least once. We also get rid of the Windows specific tests, since the warning behavior is now supposed to be platform-agnostic.

Make error messages more consistent by fixing capitalization Closes GH-5066 As a first step, let's capitalize their initial letter when it is applicable.
