• Add multiple buffer support for reads in case of simultaneous threads reading the same file

• Enhanced logging for cluster metrics and readV layer improvments

• Add time taken to unlink a file in the logging message

• Additional statistics on buffered reading added for cache hit fractions

XRootD 5.5.0-2

RAL build of Core XRootD packages
Based on the tagged official release version of 5.5.0
Adds (server side) fix from Jyotish for 5.4.3 client protection in Paged Reads
https://github.com/xrootd/xrootd/issues/1740

Proposed fix: https://github.com/xrootd/xrootd/pull/1749

XrdCeph 5.3.3-2

Xrootd 5.3.3 with https://github.com/xrootd/xrootd/commit/dd54932bfca32acab5c34d269bce81ff38f8aaa5 to fix openssl3 compatibility (for workernodes until they’re 5.5 ready)

XRootD + XrdCeph 5.3.3-9

Xrootd 5.3.3 + xrootd-ceph with ​ the following patches:
1. vector read implementation using atomic reads (xrdceph).

2. Caching layer (xrdceph).

3. Timeout increase for readv operations (xrootd)

XRootD + XrdCeph 5.3.3-11

Xrootd 5.3.3-9 with https://github.com/xrootd/xrootd/commit/dd54932bfca32acab5c34d269bce81ff38f8aaa5 (see 5.3.3-2) and a fix for caching layer.

XrdCeph 5.5.0-4

Largely for testing; 35334eec003940babff6e79f5209522b1bdc7089

Additional logging for deletes
clusterLevelLogging info
readvalgname “basic” updated to allow for a basic buffering at the readv level

XrdCeph 5.5.0-2

• Adds Correct return error code for attempted write on existing file with O_EXCL is set (permission denied).

• Adds timestamp info for ceph_posix calls.

• Disable POSC at XrdCeph layer (https://github.com/stfc/xrootd-ceph/pull/30 ), as proxy+ceph disabled it, but a merged configuration does not. POSC results in all files being treated as folders.
