See the dlopen(3) ++man page for more information. ++ ++This can be useful with Apache httpd, where two different modules are ++loaded like: ++ ++1. mod_foo.so uses library "libfoo.so" ++ libfoo.so defines a function "SomeSym" ++2. mod_bar.so uses library "libbar.so" ++ libbar.so defines a different "SomeSym" function ++ ++By default, mod_bar or mod_foo would use the "SomeSym" definition from ++the "wrong" library depending on the load order. If RTLD_DEEPBIND is ++used, the "SomeSym" definition will always be mapped to the definition ++from the corresponding dependent library. This can avoid symbol ++conflicts. ++ ++There are some risks with using RTLD_DEEPBIND, in particular potential ++issues with modules written in C++. It is not recommended to enable ++$APR_DEEPBIND unless it solves a specific problem and after thorough ++testing of the configuration. diff --git a/SPECS/apr.spec b/SPECS/apr.spec index 2743cce..8456a3b 100644 --- a/SPECS/apr.spec +++ b/SPECS/apr.spec @@ -6,7 +6,7 @@ Summary: Apache Portable Runtime library Name: apr Version: 1.6.3 -Release: 11%{?dist} +Release: 12%{?dist} # ASL 2.0: everything # ISC: network_io/apr-1.4.6/network_io/unix/inet_?to?.c # BSD with advertising: strings/apr_snprintf.c, strings/apr_fnmatch.c, @@ -122,7 +122,7 @@ popd %files %defattr(-,root,root,-) -%doc CHANGES LICENSE NOTICE +%doc CHANGES LICENSE NOTICE README* %{_libdir}/libapr-%{aprver}.so.* %files devel @@ -141,6 +141,9 @@ popd %{_datadir}/aclocal/*.m4 %changelog +* Wed Jun 23 2021 Joe Orton - 1.6.3-12 +- document $APR_DEEPBIND env var (#1886222) + * Thu Jun 11 2020 Joe Orton - 1.6.3-11 - only enable RTLD_DEEPBIND if $APR_DEEPBIND is set in env (#1845912)
