ICAT Server (SP & RK):
- SP working on making Datafile search configurable
- RK: ICAT Schema changes done. Pull request is in. Expected to release in icat.server 4.10.
- Bug fix for DfRestorer bug ready for next release.
Filesystem locking change pull request is ready. Enables concurrent access to the filesystem.
- requires plugins to be recompiled (if they inherit from mainstorage.
- or make a new call if they just implement the interface.
- ACTION (All): plugin authors to read and comment on RK’s email to icatgroup.
- Made new release with small change for own needs.
New snapshot release for Topcat 2.4.1
- getSize() call rewritten to improve performance.
- slight change to address issue where new user in same browser can see previous user’s cart and browse path.

- New starter in November: Louise Davies joins as a developer.
- SP increasing hours from 70% to 90% of full time in November.

- Had a student working; done good work; pull requests on the way.
- Continuing development of the new data portal.
- Have one early adopter who is providing helpful feedback.
Vulnerability in Apache HttpClient used in ICAT Server
- Github are now scanning our code for security vulnerabilities in our dependencies. This is only visible to project administrators.
- An alert was posted for the Apache HttpClient version 4.3.4 which is used by all versions of ICAT Server since 4.4.0.
CVE-2015-5262 More information
Vulnerable versions: < 4.3.6
Patched version: 4.3.6
http/conn/ssl/SSLConnectionSocketFactory.java in Apache HttpComponents HttpClient before 4.3.6 ignores the http.socket.timeout configuration setting during an SSL handshake, which allows remote attackers to cause a denial of service (HTTPS call hang) via unspecified vectors.
- RK and SP think that it is unlikely to present a danger to ICAT systems provided they have the ‘ip’ property configured to restrict access to ICAT to whitelisted ip address ranges.
- SP will include a fix (by upgrading the dependency to 4.3.6) in the next bug fix release of ICAT server (4.9.2)
INFRAEOSC-5 ExPaNDS H2020 proposal (SP)
- SP attending meeting at Heathrow next week.
- Work will establish a standard ontology for metadata in the catalogues used at facilities such as ISIS and DLS.
- Implements and adapts some of the output of PaNOSC (including ESRF) for other facilities.
- SP interested in possible changes to ICAT API.
- PSI (who are creating the SciCat metadata catalogue for ESS and presented at the last face to face meeting) are involved.
Google Dataset search (GC)
- GC has made ISIS data available through Google’s Dataset search facility.
- Many expressed interest in how this was achieved.
- ACTION: GC to post to the email group an explanation of how it was done.
