These definitions are directly derived from the RFC, so it should be safe
to cast them. clang complains about the different types, so cast them
explicitly.
The AES code historically has different build options for various size/speed
trade-offs. We never made use of them, so just drop the obsolete code. The code
now has four hard-coded fixed tables, both inverse and original.
Adds a flex/bison based parser for settings_t. It provides several
improvements over the previous parser e.g. quoted strings (with escape
sequences), unlimited includes, more relaxed newline handling, better
syntax error reporting, and a distinction between empty and unset
values (key = vs. key = "").
Found due to %option nodefault. A match for } was actually missing
and # was not properly matched if it was part of an include statement
on the last line of a file that did not end with a newline.
With Bison 3.x support for YYLEX_PARAM has been removed and %lex-param
should be used. Unfortunately, that option does not take expressions.
Instead we use a wrapper function that calls the lexer with the proper
scanner object, which should also be backward compatible to older Bison
versions.
This is not thread safe. If threads are reading from pointers to existing
values they could get a partially updated invalid value.
Refactored assignment to a separate function.
This parser features several improvements over the existing one.
For instance, quoted strings (with escape sequences), unlimited includes,
relaxed newline handling (e.g. at the end of files or before/after { and }),
and the difference between empty and unset values (key = vs. key = "").
It also complains a lot more about invalid syntax. The current one accepts
pretty odd stuff (like settings or sections without name) without any
errors or warnings.
This enumerator is a wrapper around glob(3). If that function is not
supported NULL is returned. If no files match or an error occurs during
the pattern expansion an error is logged and the enumerator simply returns
no items.
RFC: if GLOB_ERR is not supplied glob returns GLOB_NOMATCH if e.g. the
base directory of the pattern does not exist, which would otherwise
result in an error. This way there is at least a clear error message in
case of a typo.
__cmp__() is not supported anymore with Python 3 and cmp() is deprecated.
Instead rich comparisons should be used (only __lt__() is required for
sorting).
