This would be a problem if e.g. only some files in the priv dir were changed, since calls to code:lib_dir or code:priv_dir would then point to the old location of the application. This has been corrected - now code:replace_path/2 will be called for all applications that are changed (i.e. when the application's vsn is changed in the .rel file). --- lib/sasl/src/release_handler.erl | 40 +++++++++++++++++++++++++++++++++----- lib/sasl/src/release_handler_1.erl | 32 +++++++++++++++--------------- 2 files changed, 51 insertions(+), 21 deletions(-) (limited to 'lib/sasl/src') diff --git a/lib/sasl/src/release_handler.erl b/lib/sasl/src/release_handler.erl index eb29787103..ab54b1d00b 100644 --- a/lib/sasl/src/release_handler.erl +++ b/lib/sasl/src/release_handler.erl @@ -291,7 +291,8 @@ check_script(Script, LibDirs) -> release_handler_1:check_script(Script, LibDirs). %%----------------------------------------------------------------- -%% eval_script(Script, Apps, LibDirs, Opts) -> {ok, UnPurged} | +%% eval_script(Script, Apps, LibDirs, NewLibs, Opts) -> +%% {ok, UnPurged} | %% restart_new_emulator | %% {error, Error} %% {'EXIT', Reason} @@ -299,9 +300,13 @@ check_script(Script, LibDirs) -> %% net_kernel:monitor_nodes(true) before calling this function. %% No!

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/src/release_handler_1.erl | 59 ++++++++++++++------------------------ 1 file changed, 22 insertions(+), 37 deletions(-) (limited to 'lib/sasl/src') diff --git a/lib/sasl/src/release_handler_1.erl b/lib/sasl/src/release_handler_1.erl index 3d6bc9fbc3..ff62f847ac 100644 --- a/lib/sasl/src/release_handler_1.erl +++ b/lib/sasl/src/release_handler_1.erl @@ -33,7 +33,7 @@ %% libdirs = [{Lib, LibVsn, LibDir}] - Maps Lib to Vsn and Directory %% unpurged = [{Mod, soft_purge | brutal_purge}] %% vsns = [{Mod, OldVsn, NewVsn}] - remember the old vsn of a mod -%% before it is removed/a new vsn is loaded; the new vsn +%% before a new vsn is loaded; the new vsn %% is kept in case of a downgrade, where the code_change %% function receives the vsn of the module to downgrade %% *to*. @@ -224,7 +224,7 @@ eval({load_object_code, {Lib, LibVsn, Modules}}, EvalState) -> FName = filename:join([LibDir, "ebin", File]), case erl_prim_loader:get_file(FName) of {ok, Bin, FName2} -> - NVsns = add_new_vsn(Mod, Bin, Vsns), + NVsns = add_vsns(Mod, Bin, Vsns), {[{Mod, Bin, FName2} | Bins],NVsns}; error -> throw({error, {no_such_file,FName}}) @@ -258,32 +258,21 @@ eval({load, {Mod, _PrePurgeMethod, PostPurgeMethod}}, EvalState) -> {value, {_Mod, Bin, File}} = lists:keysearch(Mod, 1, Bins), % load_binary kills all procs running old code % if soft_purge, we know that there are no such procs now - Vsns = EvalState#eval_state.vsns, - NewVsns = add_old_vsn(Mod, Vsns), code:load_binary(Mod, File, Bin), % Now, the prev current is old.
