Package: release.debian.org
Severity: normal
User: release.debian....@packages.debian.org
Usertags: unblock
Please unblock package libevent
[ Reason ]
libevent in testing has a ftbfs bug with glibc 2.36: #1023284
[ Impact ]
The package libevent 2.1.12-stable-5 recompiled with glibc 2.36 breaks the ABI
by removing the symbol evutil_secure_rng_add_bytes.
[ Tests ]
Tests and autopkgtest passed
[ Risks ]
Low risks, the issue has been discussed upstream
(https://github.com/libevent/libevent/issues/1393) and the patrch, which is
already implemented in other distribs, has been accepted upstream
(https://github.com/libevent/libevent/pull/1427). The patch noops the function
evutil_secure_rng_add_bytes when arc4random is already provided by the system.
[ Checklist ]
[X] all changes are documented in the d/changelog
[X] I reviewed all changes and I approve them
[X] attach debdiff against the package in testing
[ Other info ]
The package should have been update sooner (before freeze), the first attempt
was to change the package name to libevent-2.1-7a, as in Ubuntu, the new
package went in NEW queue and was rejected (2.1.12-stable-7), then then
question was asked upstream to find a better solution.
Thanks in advance!
