From d92cf25f90a398c7f17466f804df020586cb2c1f Mon Sep 17 00:00:00 2001 From: Siri Hansen Date: Thu, 7 Jul 2011 10:58:57 +0200 Subject: Allow appup instruction delete_module module which is not loaded The appup instruction 'delete_module' would cause a crash during upgrade if the module to be deleted was not loaded. The reason was that the release_handler tried to read the version number of the old module after the code path had changed to point to the new version of the application. Thus, if the module had not been loaded before the upgrade, there would no longer be any such module in the path (delete_module indicates that the module is deleted from the new version of the application). This is corrected by letting the release_handler read the old version of the module only if the module is updated - not if it is removed. And it is always read before the code path is changed. --- lib/sasl/test/release_handler_SUITE.erl | 63 ++++++++++++++++++++-- .../test/release_handler_SUITE_data/Makefile.src | 28 +++++++--- .../test/release_handler_SUITE_data/lib/README | 9 +++- .../lib/b-1.0/ebin/b.app | 7 +++ .../lib/b-1.0/src/b_lib.erl | 3 ++ .../lib/b-1.0/src/b_server.erl | 37 +++++++++++++ .../lib/b-2.0/ebin/b.app | 7 +++ .../lib/b-2.0/ebin/b.appup | 3 ++ .../lib/b-2.0/src/b_lib.erl | 3 ++ .../lib/b-2.0/src/b_server.erl | 37 +++++++++++++ 10 files changed, 183 insertions(+), 14 deletions(-) create mode 100644 lib/sasl/test/release_handler_SUITE_data/lib/b-1.0/ebin/b.app create mode 100644 lib/sasl/test/release_handler_SUITE_data/lib/b-1.0/src/b_lib.erl create mode 100644 lib/sasl/test/release_handler_SUITE_data/lib/b-1.0/src/b_server.erl create mode 100644 lib/sasl/test/release_handler_SUITE_data/lib/b-2.0/ebin/b.app create mode 100644 lib/sasl/test/release_handler_SUITE_data/lib/b-2.0/ebin/b.appup create mode 100644 lib/sasl/test/release_handler_SUITE_data/lib/b-2.0/src/b_lib.erl create mode 100644 lib/sasl/test/release_handler_SUITE_data/lib/b-2.0/src/b_server.erl (limited to 'lib/sasl/test') diff --git a/lib/sasl/test/release_handler_SUITE.erl b/lib/sasl/test/release_handler_SUITE.erl index d1939694ea..9c7733b7ec 100644 --- a/lib/sasl/test/release_handler_SUITE.erl +++ b/lib/sasl/test/release_handler_SUITE.erl @@ -55,7 +55,7 @@ win32_cases() -> %% Cases that can be run on all platforms cases() -> -
