Fix out-of-bounds read in error code format parsing (#4934) 2026-09-07 11:35:29 -07:00

21d4cc15c8 Reject sign-aware zero padding in std::exception and error_code formatters
Treat a leading '0' as the zero flag rather than the start of the width so
it is rejected (as in the core formatter) instead of being silently consumed.
Also trim the exception_align test to the cases this actually introduces.

Support width and alignment in std::exception formatter (#4860)
* Support width and alignment in std::exception formatter

The formatter for std::exception (and std::exception_ptr) previously
accepted only the optional 't' type-name specifier, so standard fill,
align and width specifiers were rejected with "unknown format
specifier". This made it impossible to pad or align exception messages,
e.g. when laying them out in a log column.

Parse the standard fill/align/width specifiers (as the std::filesystem::
path formatter already does) and apply them when writing the message.
Dynamic width ({:{}}) and the 'none'/'unknown exception' cases for
exception_ptr are handled too. Existing behavior ({}, {:t}, nested
exception unwinding) is unchanged.

* Update std.h

Format nested exceptions in std::exception formatter (#4844)
Detect when a std::exception also derives from std::nested_exception
(e.g. via std::throw_with_nested) and unwind the whole chain, joining
each level with ": ". The type-name flag ({:t}) is honored at every
level, and the std::exception_ptr formatter inherits this behavior.

9d13c41ce6 Format null std::exception_ptr as "none"
Change the null exception_ptr representation from "nullptr" to "none" to
convey the "no exception" state more clearly, and update the test.

std.h: Allow formatting std::unexpected type. (#4675)
In some cases, people might want to format the std::unexpected type itself,
independent of the value type, this commit makes it possible.

due to set_debug_format being hidden by private inheritance. This fix makes the function available through a using clause.
