2022-11-25Disable atomic refcounts with no-threadsJ.W. Jagersma
This is needed for building with '-march=i386 no-threads', on platforms where libatomic is not available (djgpp, specifically). The implementation now falls back to 'CRYPTO_atomic_add()', which performs plain lock-free addition in a 'no-threads' build.

2021-05-28Rework and make DEBUG macros consistent.Rich Salz
Remove unused -DCONF_DEBUG and -DBN_CTX_DEBUG. Rename REF_PRINT to REF_DEBUG for consistency, and add a new tracing category and use it for printing reference counts. Rename -DDEBUG_UNUSED to -DUNUSED_RESULT_DEBUG Fix BN_DEBUG_RAND so it compiles and, when set, force DEBUG_RAND to be set also. Rename engine_debug_ref to be ENGINE_REF_PRINT also for consistency.

2019-09-28Fix header file include guard namesDr. Matthias St. Pierre
Make the include guards consistent by renaming them systematically according to the naming conventions below For the public header files (in the 'include/openssl' directory), the guard names try to match the path specified in the include directives, with all letters converted to upper case and '/' and '.' replaced by '_'. For the private header files files, an extra 'OSSL_' is added as prefix. Reviewed-by: Richard Levitte <levitte@openssl.org> (Merged from https://github.com/openssl/openssl/pull/9333)

2019-03-14internal/refcount.h: allow non-atomic buildRichard Levitte
Configure with -DOPENSSL_DEV_NO_ATOMICS and you get refcount without atomics. This is intended for internal development only, to check the refcounting is properly coded. It should never become a configuration option, hence the name of the macro. Reviewed-by: Matthias St. Pierre <Matthias.St.Pierre@ncp-e.com> (Merged from https://github.com/openssl/openssl/pull/8479)
