The agenda was adopted as presented.

 

2. Approval of Minutes: P366 The minutes of the 3-Apr-1998 Panel meeting, as presented in P366, were approved with the following corrections: Panel members were asked to note the panel convener’s current email address, as:  

3. Matters Arising, including Action items:

3-Apr: NMS to request permission from the IST/5 secretary to pass BSI web site authorisation details to panel members and advise panel members of same.
  The BSI pages are available to IST/5 members only: [the current Userid and password are available to panel members from the Panel Convener on an ‘as needs’ basis.] [Done: 18-Dec-1998]
 
3-Apr: The Panel Convener to include the Panel comments on P351 (Electronic Working) in the UK report to WG15. [Done: 5-April-1998. See P367]

3-Apr: AJ to mail the Panel with proposed text for a NO vote recommendation on PDAM1 to IS 14515-1 for forwarding to IST/5. [Done: 27-Apr-1998. See P368]

3-Apr: Panel Convener: re 9945-1 PDAM 5 – the Panel recommends a YES vote, with no comments. [Done: 6-June-1998. See P369]

3-Apr: Panel Convener: The Panel proposes that the UK recommends that WG15 withdraw its Security Work Items, to maintain alignment with the (lack of) work in the IEEE.  [Done: 24-Apr-1998. See P371 Resolution 98-13]

  3-Apr: Panel Convener: The UK to propose that WG15 adopt the recommendations in the ‘Future of POSIX’ WG15 ad-hoc report. [Done: 24-April-1998. See WG15 N769]

3-Apr: DJ to check version control software, and to report any findings relevant to the proposed ‘Additional Utilities’ NP (P364) to the Panel email list within the next three weeks (ie, before the next WG15 meeting), for input to WG15. [Open]
 

The Panel believes that SCCS is currently the only version control software included in the scope of the current POSIX projects.
 
3-Apr: Panel Convener to convey the UK’s best wishes to WG15 on ten very successful years in the pursuit of Unix-based standardisation! [Done: 24-April-1998]

3-Apr: Panel meetings will start at 10:00 in future, commencing with the meeting on 2-Oct-1998. [Done: NB - meeting rescheduled to 18-Dec-1998]

 

4. Progress of ISO/IEC JTC1/SC22/WG15: P370, P371 Jim Oblinger has accepted the position of WG15 Convener, replacing Mr James Isaak who successfully steered the group through its first ten years. Jim Oblinger will convene his first meeting of WG15 in January 1999.     . Consideration of ISO ballots: P368, P374, P375, P376 P368, P374 and P375 were noted.   Re P375: 1003.13 was given special permission to do additional subsetting which was not defined in the base document, P1003.1. Should P1003.1 be amended to accommodate the real time profiles? The Panel considered whether this would be appropriate. AJ noted that he had been requested (in the IEEE) to look at this, and to suggest the best approach. The Panel has no objection to the introduction of feature groups, with the proviso that the base document does not become unreadable, or broken, or that individual elements of the API are not themselves sub-setted. The Panel considered that an implementation that claims conformance to the base standard should not be allowed to have less functionality than it presently does.   P376 was noted.
 
  . Actions: There were no actions outstanding relating to current ISO ballots.     . Status Report of SC22/WG15: P367 P367 was noted.     . Actions: P377 9804-06 All Member Bodies - Seek volunteers for the post of WG15 Convener, to run for three years from September 1998 at the latest. Applicants should have sponsorship from their employers and from their National Bodies. (Rolled over from 9705-55 and 9710-15) OPEN [See 9804-36] [Closed: OBE]
  The UK POSIX Panel applauds the appointment by SC22 of Mr James Oblinger to the office of WG15 Convener, and wishes him well in his new post.
 
 
9804-16 Member Bodies to respond to the subsetting proposal in PDISP ballot to 15287-2 (aka 1003.13) and indicate whether such subsetting should be supported in the base standard. [Closed: See the discussion under agenda item 4, Consideration of ISO Ballots, above.  P375 refers]

 

9804-22 All Member Bodies to identify specific issues that need to be addressed w.r.t. work in progress and co-operative development TOG/PASC/WG15 and report these to Roger Martin by May 31. [Closed: OBE]

Panel members were advised that discussions in the IEEE PASC Development body, The Open Group, and subsequently in the joint IEEE/WG15/TOG ‘Austin Group’ meeting proposes that work in progress stays with the current development groups. The Panel is aware of discussions in the Joint Procedures Committee (ProComm) (procedural experts from the IEEE, ISO and TOG), and supports the joint voting model. Ted Baker proposed (at ProComm) that, wherever there is not unanimity on a particular issue, three votes should be cast, one from each participating body, to determine a majority, which rules the day. Each participating body would apply its own procedures in determining what its vote should be. No authoritative minutes have so far emerged from ProComm.

The UK Panel approves what it understands to be the current intentions with respect to future co-operative development of the POSIX standard.

 
Action: NMS to request chair of ProComm to forward to WG15 the proposed procedures emerging from the San Diego meeting. 9804-24 All Member Bodies to review and Comment on N768 (LIS Techniques) by August 1.

[Closed: OBE]
 

WG15 N768: LIS Techniques has not been made available from WG15 either electronically or in paper form. Constructive comment is therefore problematic. The UK would be extremely interested in reviewing the paper, but have no copy to consider.  
Action: DC to request Keld Simonsen, author of the document, for a copy of N768.   [Done: 20-Dec-98.  The WG15 N768: LIS Techniques paper was issued as (SC22WG15.1269) LIS paper in May 1998, by email, with no reference to the WG15 document number.  Please accept my apologies for failing to spot the correlation.  The paper has been issued to the UK panel by email (20-Dec) and is now on the Panel web site as N768 in the WG15 pages]. 9804-35 Member bodies to continue to actively seek candidates for WG15 convener, and to report these no later than the August SC22 meeting in Copenhagen.

[Closed: OBE]

9804-36 Member bodies to propose alternative methods for continuing and maintaining the work of WG15 if there is no convener, and to report these at the August SC22 meeting in Copenhagen. [See 9804-06] [Closed: OBE]
 

See AI 9804-06 and 9804-22 above.  
Action: DC to create and post UK Action Item report to WG15, based on the above minutes.  

 

  . Resolutions: There were no WG15 resolutions not referenced by the above actions that required the Panel’s attention.   5. Progress of IEEE PASC Posix WGs

  . Consideration of IEEE ballots:     P378

Re P378, the panel convener explained the problems in applying the proposed ISO change to P1003.2b. Following discussion, the Panel is content to see the proposed ISO changes to P1003.2b dropped.   NMS reported that a number of IEEE ballots are in progress:  

  . Status Report of IEEE PASC:

1003.1g (Sockets): The Technical Editor of the document, Chris Harding, attended this section of the panel meeting and reported that it had received over 75% approval 2 years ago. ISO comment resulted in draft 6.6, mostly involving some integer/long changes to the document. This also received 75% approval. The draft was submitted to the IEEE SB, but was refused because objections had been received on the new text. Lack of participation in the IEEE ballot resolution group prevented further progress.

IEEE SEC have subsequently appointed a new ballot coordinator. A new ballot recirculation was organised, objections reviewed, and the new document is now ready for submission to the ballot group for final recirculation. It is expected that the draft will be approved by the IEEE SB in the next 3 to 6 months.

There is some concern that P1003.1g is now a couple of years behind current technology - the API of APB6 is now stable, for example. The Panel considered that the merge of P1003.1g into the base standard would not be a useful effort – better to use it as a basis of work for the Austin Group’s revision of the base standards.

It was reported that XNS, which also includes the basis of some threads work, is currently to be included in the remit of the Austin Group if and only if 1003.1g is approved – otherwise the Austin Group’s output will not include any networking interface.

The Panel debated the merits of locking the Austin Group to known, fixed technology, or of accepting and working on some evolution of the base standards: P1003.1g and XNS are technically aligned – and a POSIX standard without networking would be very restricted. The UK Panel propose that The Austin Group remit should include some form of networking interface, being XNS and/or 1003.1g.

Action: DC to add a pointer on the Panel web pages to the Austin Group pages, (http://www.opengroup.org/austin). Panel members are recommended to visit them. NMS reported that the SRAS group’s draft is due to go to ballot soon.

NMS is attempting to progress the 1003.2b work in the IEEE, and is currently chasing proposed ISO revisions – see P378. Discussion moved to recent email from Don Cragun which queried the status and reasoning behind the UK proposal (WG15 N730) to limit the ‘ring-fencing’ of identifiers by POSIX standards. The Panel felt the issue would be best resolved by putting the paper’s author in contact with the IEEE development group.

 
Action: NMS to contact Derek Jones re his proposals to limit POSIX namespace (WG15 N730 - UK Proposal: Reserved Identifiers in POSIX Standards) and suggest a way forward. MK reported that 1307.4 (Print Admin) has been terminated in IEEE. There are now no active 1307 drafts in IEEE, although the group is still in existence. Security is also dead, but 1003.1n (technical corrigenda) is progressing.

 

6. Liaison with other Standards Committees and Panels: P372, P373 P372 and P373 were noted.

NMS reported that there are moves afoot to get Linux developers more actively involved in the POSIX process, particularly the revision project.  The Linux community is also attempting to produce internal standards to avoid a diverging base.  A conformance test suite is being written.

 

  . IST/5 Report: (NMS) P369 The Panel's Q2 Report (P369) was submitted to IST/5 at its August meeting.

The Panel’s recommended response in the Letter Ballot on WG15 Proposed Record of Responses for Defect Reports 01 to 147 for IS 9945-2: POSIX Shell and Utilities - SC22 N2689 (P374) was one of approval.

The Panel had arranged a review of ISO/IEC 9945-2:1993 POSIX Part 2, Shell and Utilities (98/644635), deadline 98-09-30, and recommended a response of approval with comments to IST/5.

IST/5 agreed that the Panel Convener, Mr N Stoughton, should be the HoD at the WG’s meeting in New Orleans in January 1999, and AITS funding in respect of his attendance was authorized.

 

  . IST/5/-/14 Liaison: (DJ) Derek Jones was not present. No C status report is available.

It was noted by the panel that it has been common practice to include relevant parts of the C language definition in POSIX-based standards and guides. Inclusion was seen to be an aid to the reader, relieving him of the requirement to find the relevant portion of text in some other book. It also introduced the problem that the quoted text could become out-dated. The Austin Group were seeking guidance on the issue for its future output.
 

Action: AJ to contact IST/5/-/14 to solicit opinions on how or whether to include or reference the C standard in the Austin Group’s output.   . IST/5/-/53 (Java) (DJ) No report.

 

7. Any Other Business Move to electronic distribution of IST/5/-/15 documents: DC proposed that future mailings for the Panel would consist of the appropriate set of documents on disk, rather than the stack of paper which has up to now been the normal distribution medium. Paper copy would only be issued where no other form was available. Distribution on disk would result in cheaper mailings which could be assembled closer to the posting date, and would more closely mirror the availability of documents on the Panel's web pages.

A cover letter to the latest mailing and an email had been sent to Panel members detailing the proposal, emphasising that no response to the proposal would be taken as approval of the change.

The Panel proposed that no posting whatever would be necessary in future. The Panel authorised its secretary to send just a reminding email two weeks prior to panel meetings, pointing to the Panel web pages. Panel documents are to be emailed to the Panel membership thus ensuring that each receives a unique email reference number, one document per email, in addition to a reference to the web pages. The Panel document list would continue to be maintained; all panel documents would therefore also have an email reference, but not all panel emails would necessarily have a panel document number.
 

Action: DC (Panel Secretary): Panel documents to be emailed to the Panel members in future, together with a two-week calling notice of an upcoming panel meeting. The calling email to include a pointer to the current section of the panel’s web pages. NMS asked for volunteers to succeed him as Panel Convener, as he felt he wasn’t able to give as much time as he’d like. The Panel acclaimed his competency in the post, and asked him to continue.
