Received from J.P. Rosen,
The Ada Group of AFNOR met on 2008-10-16, in preparation for the WG9 Portland
meeting.
The group reviewed the proposed AIs. We noted that
the provided link (AI05-SUMMARY.HTML) was not up-to-date, since two AIs (104 and 105) were missing; fortunately, they were
easily retrieved from the AI data base.
Regarding the future of Extended containers
(Resolution 50-5):
Regarding future direction of the
On the technical side:
On the editorial side:
The natural way of incorporating AIs is by producing a TC, however
this would not meet the goal of having a self-contained document.
It is clear that there is no desire (nor funding) for making big changes to the
language, although the outcome of WG23 (vulnerability) should be closely
watched. A possibility is to go formally for a revision, but without any change
beyond:
• producing the integrated document resulting from TC1+Amdt1
• incorporating AIs
• possibly adding some predefined packages (like extended containers, UTF8/16 coding functions, etc)
• possibly adding some pragmas if the outcome of the work of WG23 determines some needs that could be fulfilled that way.
Such a revision (minor in effect) would also send
a positive message to the world that the language is alive and well.
Received from T. Vardanega,
1) Work performed
Struggled to keep up with the ARG work, with
particular attention to the (few) AI that have a bearing on real-time issues.
Willing and interested in investing effort in resuming HRG work for the
production of a language-specific annex to the OWGV report.
2) Issues
of interest
2.1) Unfinished business
No position at this time.
Will follow up the ARG discussion until the time of the WG9 meeting and may provide an opinion by then.
2.2) New business
Being the host for the SC22 meeting this year, I have taken the opportunity of talking to Sally Seitz to better understand the ISO-side implications of the various options.
I have therefore come to form the following opinion:
Italy consider that to fully update the Ada Standard, similar to what was done for Ada 95, is too much effort at this stage of development and user awareness of the current language standard.
It is also clear that a corrigendum is too complex
for common users: the Ada Issues that have been written up and resolved for Ada
2005 need to be incorporated into the Standard.
According to the SC22 Secretariat, in fact, it is possible to produce a new
EDITION that incorporates the corrigendum without the expense and overhead of a
new REVISION. A revision would in fact open the whole standard up for review
and be for an expansion or significant change.
I wish all attendees a productive meeting and an excellent time.
Received from J. Barnes,
A recent meeting of the BSI Ada panel discussed at length
the issue of the form of the next version of
We also had an excellent curry.
Received from R. Brukardt,
Summary:
Reasons:
(1) A Corrigendum does not offer much to users (just bug fixes).
(2) A Revision is more risky than an Amendment, as it has the potential to add confusion due to renumbering of clauses, rewording of text, use of new/changed terminology and more. One participant called it an "apocalyptic earthquake".
(3) Users
and the world have expressed interest in additions to
invariants, user-defined constraints, etc.) and in making multicore
programming easier (lock-free algorithms, transactional memories, additional
static detection/prevention of tasking errors (races, deadlock, etc.). An
Amendment or Revision is needed to provide these additions.
(4) We expect the changes to be more contained than the last Amendment (not affecting as much of the standard).
(5) An Amendment or Revision will provide more energy (and potentially participants) in the process. New ideas are more interesting than bug fixes.
(6) An
Amendment or Revision would make
Risks:
(1) Some
organization needs to step up to create a consolidated standard (as Ada Europe
did in the last cycle). Otherwise, in the absence of a full revision,
(2) Some funding will be required. If that cannot be found, progress will be much slower or non-existent. (But this is true of all of the options.) Development of the last Amendment was more than a half-time job for 3 years; that level of commitment is unlikely from a pure volunteer.

Agenda
SIGAda is a Category C Liaison to WG9 (See N414)
The OWG: Vulnerabilities was an ad hoc Working Group of ISO/IEC/JTC1/SC22 (see N469). At the plenary session of ISO/IEC/JTC1/SC22 in September 2008, the Other Working Group was instantiated as Working Group 23 of ISO/IEC/JTC1/SC22
<TBD>
At Meeting #50 (N470), we learned that SC22 has created a project to provide a cross-language comparison of the vulnerabilities that exist in various programming languages and the manner in which these vulnerabilities may be avoided or mitigated. At the JTC1 SC 22 Plenary the OWG was converted into a Working Group under SC 22 – WG 23.
The most important work for this meeting is to come to closure on the path
forward for the
In addition, we will continue the various items of work underway, including:
ASIS – what is the progress on the development of this update and what is the schedule will be for completion,
POSIX/Ada binding – leadership and direction, and
This is the "To Do" list for WG9. Some are informal action items assigned to various participants. Some are formal resolutions, which are not yet implemented. Some items are simply in suspense awaiting action by other groups.

Status: SC22 reassigned the standard to WG9 with Ted Baker as project editor. Processing of the document's confirmation by systematic review has not been completed.
Email note from Ted Baker,
I regret to say that will not be able to attend. I have exchanged several e-mails with Stephen Michell on the subject of the POSIX Ada binding standard. I provided him with a pdf version of the POSIX Ada binding document, so that he and a group of Canadian colleagues could review it. I understand that they will be estimating the scope of work that would be required to bring the standard up to date with respect to Ada and the base POSIX/Unix C-language API. There have been a few other exchanges, with a representative of Adacore Technologies and a user. The scope of the project can be scaled to fit the available human resources, by limiting the changes to only features that are not already provided by the existing POSIX Ada binding and the Ada language *and* have been requested by members of the Ada community. To this end, it might be reasonable to ask WG9 representatives to provide some e-mail lists of individuals and organizations that we could poll, to determine a list of features for which there is a demand.

ISO/IEC 15291:1999, Information Technology--Programming Languages--Ada Semantic Interface Specification (ASIS), 22.15291, Clyde Roby and Greg Gicca, Project Editors, supported by the ASIS Rapporteur Group.
This document was "confirmed" by JTC1 in its 2004 systematic review.
Report from Meeting #54
The scope of the ARG's ASIS activity is "to add or modify interfaces of the current ASIS specification in order to permit representation of the new language features that have been added to ISO/IEC 8652 since 1995. Care should be given to backward compatibility of existing ASIS applications."
A collection of ASIS items have been developed to meet this objective. To date, 24 SIs have been approved by the ARG and incorporated into the latest draft of the document. Eight SIs are still in work: SI99-0007, SI99-0019, SI99-0021, SI99-0024, SI99-0030, SI99-0035, SI99-0036, & SI99-0037.
Of these, most require only minor work. The largest and most difficult is SI99-0024, the purpose of which is to provide a semantic model in addition to existing syntactic model. The model has been developed, but needs additional review, as well as agreement on an approach for its documentation.
Additional action that is likely needed includes an update to the "ASIS technical concepts" section, both to be consistent with the current standard (e.g., remove references to obsolescent features), as well as to illustrate use of the new features (e.g., the semantic model).
Completion of SI-024, (and the related changes to other parts of the document) is likely to require several additional meetings. Having a complete draft available by the Ada-Europe 2009 meeting seems achievable, but prior to that may be challenging.

WG9 [N406]: Procedures of the ARG
Resolution 44-4 of [N428]: The convener directs the chair of the ARG to send the list of AIs intended for submission to WG9 to NB and liaison representatives at the time they enter the 'editorial review' state. It would then be the duty of each NB and liaison representative to circulate this information within their own organization for the purpose of developing a position for the forthcoming meeting of WG9.
WG9 N464r, N468: Terms of reference and approach for the revision of ISO/IEC 15291 (approved by Resolution 50-7 [N470])
Resolution 50-6 of [N470]: Until otherwise directed by WG9, the ARG is requested to observe the following priorities in its work: (1, the highest priority) develop a revision of ISO/IEC 15291, ASIS; (2) respond to Defect Reports and/or Ada Issues on ISO/IEC 8652; (3) develop Technical Reports or Standards improving the Ada libraries--notably with respect to containers; and (4) consider proposals for extending the language.
WG9 requests that the ARG consider solutions to the problem described in comment 12 of N459 [containers], as well as other possible extensions to the standard library, and develop a New Work Item Proposal for a Type 2 Technical Report that will provide a "trial use" specification to users and implementers, and that will be suitable for future standardization.

Request from ARG |
The ARG Rapporteur posed the following question: Should it be permitted to select AIs of the amendment and implement them upon Ada 95? |
|
Discussion |
The ARG Rapporteur reported that there has been email discussion of applying some of the AIs of the amendment to the unamended language. It has been suggested that the AIs that constitute "corrections" or "clarifications" should be applied to old compilers. The Convener stated that AIs become part of the standard only when incorporated into a Corrigendum or an Amendment. AIs that are not incorporated but result in changing tests indicate only that the test was incorrect. Randy Brukardt (who operates the Ada Conformity Assessment Authority) noted that currently the ACATS suite is updated only for the Technical Corrigendum and has not been updated as a result of any AIs since then. As this is the operational test of conformity, it would not be possible to certify a compiler as conforming if it were to apply AIs processed since that date, but short of the full amendment. As a result of the discussion, the following resolution was approved. |
|
Resolution |
Resolution 49-7:WG9 recommends that all effort in enhancing the ACATS should be dedicated to tests appropriate for assessing conformance to Ada 2005. |
The ARG has its "usual" motion for the June meeting for approval of a series of AIs. See the list below. Pointers to retrieve the AIs are included. The list includes one Ada 95 AI: this is not a mistake; this AI makes it possible for existing compilers to support new Ada 2005 syntax in their Ada 95 implementation, in order to ease transition to the new language.

There has been no meetings or actions since the last meeting of WG9. However
the HRG is preparing to take on the task of producing the Ada-specific Annex to
the OWG-V report. We expect to be able to start this work following the
forthcoming meeting of OWG-V (WG23) on 29/9 - 1/10.
PRG Report to WG9
The PRG was created at SC22/WG9 meeting 51,
To date I have not called a meeting of the full PRG. An email reflector has been created at
posix-ada-comment@ada-auth.org
I have created a draft set of procedures from the ARG procedures. I can present them to WG9, but since a PRG meeting has not considered them, I think this is premature.
I have worked with Randy Brukhardt to set up a web-site similar to ada-auth.org, but this work is still in its beginnings.
I have met with Ted Baker, Brad Moore and Luke Wong in an informal review of IS14519. This "informal" meeting happened 19-21 February 2007 at Ted's locale and was a 3-day review of the existing document and a Canadian contribution that we prepared in Oct and Nov 2006. From this meeting we have a list of items that need likely attention. It is a large list, but many of the items can likely be dealt with directly. One of the issues that we would need to come to terms with is if we treat these as AI's are treated, can we lump them into a few larger PI's or will we need a plethora of PI's. My intention is to call a meeting and use this list as a starting point for discussions.
From this meeting and subsequent events I can report:
• Ted is willing to continue as editor, but has no financial resources to put to this task.
• Luke Wong was intending to volunteer as Rapporteur. This looks like it will not happen, which leaves me in a challenging position. My workload (and no funding) is one of the reasons why more progress has not been made.
• The standard needs updating, at least minimally. We reviewed most of the significant decisions from the earlier binding activities and believe that they are still correct, such as not implementing access to POSIX features that conflict with Ada-provided services, such as task (or thread) management, or IO, or not implementing services that were too large and troublesome, such as System V material, logging, etc. The main issues that need attention are those from mistakes in the current binding and changes because of new POSIX errors, symbols, and new capabilities in services that we already provide.
• There is some interest in seeing this standard progressed, but to date we have not found anyone wanting to fund one or more of us to do the work. That being said, if this is an all-volunteer effort it will run at a minimal rate.
Received from Stephen Michell,
Report to WG9 on status of Ada-POSIX Binding Investigation
Stephen Michell, Rapporteur PRG, November 2007.
Project: Revision of ISO/IEC 14519:1998 Ada POSIX Binding
Calling meeting for Feb 6-8 in
willing to host us 6-8 Feb. Hopefully we can overlap with ARG for Friday morning.
Analysed existing Ada POSIX Binding document, 9945:2008(Draft) to identify
What is still valid
What we don't want to include
(c-specific, already in Core Ada or in Annexes)
Parts that have been obsoleted by 9945 since 1996
(and there are quite a few)
Developed list of issues - about 1800 individual data points and categorized them.
A small group (Michell, Moore,
Wong) met in
analysis, reasons and to gain his perspective on various issues.
What we are left with is a set of approximately 350 individual datapoints that need further analysis. These have a significant variety of reasons for needing further analysis. Most will be solved by a careful review and a change of a name or just a POSIX reference in the document. A few might need new the possible addition of new procedures, constants or types. A very few could require new packages and functionality defined.
We have a plan to develop a web site in parallel with ada-auth.org mainitained by Randy Brukhart, and to develop a few POSIX Issues.
POSIX Issues
We predict only a small number (20-50) POSIX Issues needed to capture analysis done or to be done.
PRG Interest
There is a group of about 10 people that have expressed interest in the activity. An email reflector has been set up but has not been used much yet. (need web site to support the activity).
PRG Procedures
I have prepared a set of procedures for presentation and review at the first meeting. This document came from ARG procedures. I expect that some simplification will occur.
Standardization
The final product needs IEEE and ISO/IEC/JTC1 approval processes. This may govern the final product. Ideally an amendment or even a technical corrigendum might be possible, if IEEE agrees. We (Ted) asked IEEE to waive copywright but have had no response.
Austin Group has offered to help, but in non-technical ways. I expect that they could be used for sanity checks and to help navigate the EEE balloting processes.
Workload
The amount of work to be done probably translates to about 1 person years of work. Since we are unfunded, 5 or 6 people over 2 years could probably do this work.
Officers
It seems as though I should stay on as Rapporteur. My heavy workload interferes with progress, but given the lack of interest of anyone else wanting to lead this effort, it seems like the best alternative. Ted Baker has agreed to stay involved as editor. Given Ted's expertise and knowledge of the toolset in producing the document, this will also minimize our effort.
Report to WG9 on status of Ada-POSIX Binding Investigation
Stephen Michell, Rapporteur PRG, June 2008.
Project: Revision of ISO/IEC 14519:1998 Ada POSIX Binding
Officers:
Stephen Michell, Rapporteur
Ted Baker, Editor
Membership: Stephen Michell, Ted Baker, Luke Wong, Canada, Brad Moore, Canada, Matt Gingell, USA, Michael Gonzales-Harbour, Spain, some on internet as observers.

2009 in
Meeting 2-4 Feb 2008
Discussed PRG Procedures document. The document
discusses the way that PIs are discussed, but not how the standard itself is
dealt with. The document does not include IEEE maintenance issues. We probably
need to make this a joint maintenance committee and figure out how to make this
work. Steve and Ted have an action Item to discuss with IEEE how a standards
group can be organized.
Discussed various approaches for standardization. The largest challenge is the IEEE balloting effort, as it would seem that we are unlikely to build the balloting membership with the proper mix of vendors, users, acedemia to carry a successful ballot. We have tried to identify IEEE officers to help us examine alternative approaches, but have no responses to any queries for information. I have also been thinking that ISO could use their copywrite to unilaterally issue an amendment to the document, but need to hold discussions with ITTF and the JTC1 secretariat to determine feasibility of such an approach.
We took the list of issues developed in 2007 and developed 22 PI's. These PI's
are a statement of the issue and a collation of the issues collected. Each PI was
assigned to a member to develop a primary writeup, analysis
and proposed approach. In many cases the proposed approach will be no action
(since the
Meeting 15-16 June 2008
A small subset met in
Although the PRG web site is up, no PI's have been placed on this site, due to the immaturity of the issues identified and lack or writeups.
Progress has been slower than I want, and we are not getting the attendance
necessary. I have therefore proposed holding the next meetings by monthly phone
conferences, with a goal to push the generation and review of PI's. A full PRG
meeting is planned for
Developed list of issues - about 1800 individual data points and categorized them.
POSIX Issues
We predict only a small number (30-40) POSIX Issues needed to capture analysis done or to be done.
PRG Interest
There is a group of about 10 people that have expressed interest in the activity. An email reflector has been set up but has not been used much yet. (need web site to support the activity).
PRG Procedures
I have prepared a set of procedures for presentation and review at the first meeting. This document came from ARG procedures. We need to include more focus on standardization.
Standardization
The final product may need IEEE and ISO/IEC/JTC1 approval processes. This may govern the final product. Ideally an amendment or even a technical corrigendum might be possible, if IEEE agrees. We (Ted) asked IEEE to waive copyright but have had no response.
Austin Group has offered to help, but in non-technical ways. I expect that they could be used for sanity checks and to help navigate the IEEE balloting processes, if we use this process.
Work Item:
We should not need to create an NP for maintenance or development of a TC. At this point we would fail the requirement for 5 countries but could likely add some supporting folks.
Workload:
The amount of work to be done probably translates to about 1 person years of work. Since we are unfunded, 5 or 6 people over 2 years could probably do this work.
