+Subject: [PATCH] Don't look into source package provides in depsolving
+
+Fixes regressions from commit 75ec16e660e784d7897b37cac1a2b9b135825f25:
+the newly added provides of to-be-built packages were being used for
+dependency resolution, such as spec satifying its own buildrequires,
+and matched against conflicts in installed packages.
+
+Source packages cannot obsolete anything or provide capabilities or files
+to transactions, don't add them to rpmal at all. Explicitly skip checks
+against source provides, similarly to what we already did with obsoletes.
+
+Fixes: #1189
