The only difference between the two flavors will be the public header files, linked symbols and library name. Note that this add a regression in term of performance, since the implementation of liburcu-mb adds memory barriers on the reader side which are not present in the original liburcu-signal implementation. 2) Adding the deprecated attribute to every public functions exposed by the liburcu-signal flavor. At this point, tests for liburcu-signal will also be removed from the project. There will be no more support for this flavor. 3) Removing the liburcu-signal flavor completely from the project. Finally, here is a tentative versions release of mine for each phase: 1) 0.15.0 [October 2023] (also TSAN support yay!) 2) 0.15.1 3) 0.16.0 || 1.0.0 (maybe a major bump since this is an API breaking change) -- Olivier Dion EfficiOS Inc. https://www.efficios.com _______________________________________________ lttng-dev mailing list lttng-dev@lists.lttng.org https://lists.lttng.org/cgi-bin/mailman/listinfo/lttng-dev
