+
+  * server: rest: implement max URI path and query length request limits
+
+  * server/rest: implement request access log and log the query part of
+    URL and the user agent
+
+  * api: access: log to separate file, use syslog to errors only to reduce
+    syslog spam
+
+  * client: set HTTP connect timeout to 10 seconds
+
+  * client: sent TCP keep-alive after 2 minutes instead of the Linux default
+    of two hours.
+
+  * CLI completion: fix ACL path completion
+
+  * fix #2988: allow one to enable automatic verification after finishing a

+
+  * fix #2934: list also new to-be-installed packages in updates
+
+  * apt: add /changelog API call similar to PVE

+//! # Locking
+//!
+//! Since PBS allows multiple potentially interfering operations at the
+//! same time (e.g. garbage collect, prune, multiple backup creations
+//! (only in seperate groups), forget, ...), these need to lock against
+//! each other in certain scenarios. There is no overarching global lock
+//! though, instead always the finest grained lock possible is used,
+//! because running these operations concurrently is treated as a feature
+//! on its own.
+//!
+//! ## Inter-process Locking
+//!
+//! We need to be able to restart the proxmox-backup service daemons, so
+//! that we can update the software without rebooting the host. But such
+//! restarts must not abort running backup jobs, so we need to keep the
+//! old service running until those jobs are finished. This implies that
+//! we need some kind of locking for modifying chunks and indices in the
+//! ChunkStore.
+//!
+//! Please note that it is perfectly valid to have multiple
+//! parallel ChunkStore writers, even when they write the same chunk
+//! (because the chunk would have the same name and the same data, and
+//! writes are completed atomically via a rename). The only problem is
+//! garbage collection, because we need to avoid deleting chunks which are
+//! still referenced.
+//!
+//! To do this we use the
+//! [ProcessLocker](../tools/struct.ProcessLocker.html).
+//!
+//! ### ChunkStore-wide
+//!
+//! * Create Index Files:
+//!
+//!   Acquire shared lock for ChunkStore.
+//!
+//!   Note: When creating .idx files, we create a temporary .tmp file,
+//!   then do an atomic rename.
+//!
+//! * Garbage Collect:
+//!
+//!   Acquire exclusive lock for ChunkStore. If we have
+//!   already a shared lock for the ChunkStore, try to upgrade that
+//!   lock.
+//!
+//! Exclusive locks only work _between processes_. It is valid to have an
+//! exclusive and one or more shared locks held within one process. Writing
+//! chunks within one process is synchronized using the gc_mutex.
+//!
+//! On server restart, we stop any running GC in the old process to avoid
+//! having the exclusive lock held for too long.
+//!
+//! ## Locking table
+//!
+//! Below table shows all operations that play a role in locking, and which
+//! mechanisms are used to make their concurrent usage safe.
