Patch Package: OTP 20.3.8.21 Git Tag: OTP-20.3.8.21 Date: 2019-04-17 Trouble Report Id: OTP-14746, OTP-15551, OTP-15657, OTP-15660, OTP-15690, OTP-15691, OTP-15716, OTP-15717, OTP-15757, OTP-15758, OTP-15763, OTP-15766 Seq num: ERIERL-143, ERIERL-324, ERIERL-334, ERIERL-342, ERL-869 System: OTP Release: 20 Application: common_test-1.15.4.2, erl_interface-3.10.2.2, erts-9.3.3.10, snmp-5.2.11.1, ssh-4.6.9.4, tools-2.11.2.1 Predecessor: OTP 20.3.8.20 Check out the git tag OTP-20.3.8.21, and build a full OTP system including documentation. Apply one or more applications from this build as patches to your installation using the 'otp_patch_apply' tool. For information on install requirements, see descriptions for each application version below. --------------------------------------------------------------------- --- HIGHLIGHTS ------------------------------------------------------ --------------------------------------------------------------------- OTP-15691 Application(s): snmp Related Id(s): ERIERL-324 [snmp|agent] Add a get-mechanism callback module (and a corresponding behaviour). The agent calls this module to handle each get (get, get-next and get-bulk) request. --------------------------------------------------------------------- --- POTENTIAL INCOMPATIBILITIES ------------------------------------- --------------------------------------------------------------------- OTP-15717 Application(s): common_test Related Id(s): ERIERL-334 The test result when a hook function fails is in general the same as if the function that the hook is associated with fails. For example, if post_init_per_testcase fails the result is that the test case is skipped, as is the case when init_per_testcase fails.This, however, was earlier not true for timetrap timeouts or other error situations where the process running the hook function was killed. This is now corrected, so the error handling should be the same no matter how the hook function fails. --------------------------------------------------------------------- --- OTP-20.3.8.21 --------------------------------------------------- --------------------------------------------------------------------- --- Fixed Bugs and Malfunctions --- OTP-15551 Application(s): erts, otp Fixes of install/release phase in build system. -- The source tree was modified when installing/releasing and/or applying a patch. -- Some files were installed with wrong access rights. -- If applying a patch (using otp_patch_apply) as another user (except root) than the user that built the source, the documentation was not properly updated.

For example, if post_init_per_testcase fails the result is that the test case is skipped, as is the case when init_per_testcase fails.This, however, was earlier not true for timetrap timeouts or other error situations where the process running the hook function was killed. This is now corrected, so the error handling should be the same no matter how the hook function fails. OTP-15758 Application(s): common_test Related Id(s): ERIERL-342 In some rare cases, when two common_test nodes used the same log directory, a timing problem could occur which caused common_test to crash because it's log cache file was unexpectedly empty. This is now corrected. --- Improvements and New Features --- OTP-14746 Application(s): common_test Related Id(s): ERIERL-143 Two new common_test hook functions are introduced: post_groups/2, which is called after Suite:groups/0 post_all/3, which is called after Suite:all/0 These functions allow modifying the return values from the groups/0 and all/0 functions, respectively. A new term, {testcase,TestCase,RepeatProperties} is now also allowed in the return from all/0. This can be used for repeating a single test case a specific number of times, or until it fails or succeeds once. OTP-15716 Application(s): common_test OTP internal test improvements.

OTP-15657 Application(s): erts, otp, tools Minor fixes for make clean. OTP-15660 Application(s): erts Related Id(s): ERL-869 Fixed a bug in all ets:select* and ets:match* functions that could in some rare cases lead to very poor performance. OTP-15690 Application(s): erts Related Id(s): PR-2172 Fix a possible deadlock when terminating the ERTS caused by a dirty scheduler not releasing it's run-queue lock when terminating. OTP-15766 Application(s): erts Add missing documentation of new external tags NEW_PID, NEW_PORT and NEWER_REFERENCE introduced in OTP 19. These new tags are planned to be "activated" in OTP 23 when distribution capability flag DFLAG_BIG_CREATION becomes mandatory. Older nodes (>= 19) are able to decode these new tags and send them back to the new node. Nodes older than OTP 23 will however never encode their own local pids, ports and references using the new tags.
