Thread Safety Notes
by Andy Heninger Sept. 22, 2014

Sept. 22, 2014

I've been looking over the thread safe additions to localtime.c, and have a few comments. 1. Use of C's 'volatile' declaration is not sufficient to implement fully thread-safe double-checked locking. The complications are confusing and subtle. Here is a paper that goes into the question in depth: http://www.aristeia.com/Papers/DDJ_Jul_Aug_2004_revised.pdf The bottom line is that doing it right needs memory barrier operations - a read acquire and write release or equivalent for the flag variable being tested. Volatile does not guarantee these. C11 has the necessary functions, but is not yet widely available. [ http://www.open-std.org/jtc1/sc22/WG14/www/docs/n1570.pdf ] Compilers mostly have non-standard extensions available that will do the job, often modeled after those in gcc. 2. The function gmtcheck() needs to recheck the gmt_is_set flag after acquiring the lock. As it stands, multiple threads could replicate the initialization, overwriting a previously set gmtptr in the process. This is unrelated to the volatile question. 3. The volatile variable lcl_is_set is referenced while not holding the lock in only one place, in localtime_r(). And from there the function localtime_tzset() is unconditionally called, which unconditionally acquires the lock. With minor refactoring, all access to lcl_is_set could be from code that is holding the lock, which would allow lcl_is_set to be an ordinary variable with no special thread safety considerations. If it were up to me, I would probably remove use of the double-checked idiom, and rely on solely lock(). Slightly slower, but simple, portable and safe. The alternative is to #define some compiler-dependent atomic operations. Thanks, -- Andy Heninger

valgrind errors loading UTC
by Richter, Jörg Sept. 8, 2014

Sept. 8, 2014

When loading ‚UTC‘ the function tzload seems to use an uninitialized value here: localtime.c:574: for (i = 0; i < sp->typecnt; ++i) if (sp->types[i] == 0) // <- sp->types[0] is uninitialized (sp->typecnt is 1) break; It might be a user error on my side. But I am unable to spot it. Note that the UTC file was generated with an older version. This is with tzcode2014g - Jörg
