Summary

In addition of being the base branch for the upcoming V2.0 release, this PR updates AGAS runtime behavior, release/version metadata, release-list tooling, and documentation across HPX.

AGAS Runtime Updates

  • RPC timeout & locality resolution (libs/full/agas_base/src/rpc_timeout.cpp, libs/full/agas_base/src/detail/hosted_locality_namespace.cpp)
    • RPC timeout storage now requires a nonzero millisecond value.
    • Locality resolution passes unresolved futures directly to timeout handling.

Release, Build, and Documentation Updates

  • Build and version metadata (CMakeLists.txt, libs/core/version/src/version.cpp)

    • Bumped version date to 20260930.
    • Updated release tag to -rc1.
    • Updated version file copyright year.
  • Release-list generation (tools/generate_issue_pr_list.sh, docs/sphinx/contributing/release_procedure.rst)

    • Script now uses GitHub CLI and jq.
    • Adds milestone validation and fails on query errors.
    • Applies shared limits and formats titles for reStructuredText.
    • Release procedure docs updated to reference the renamed script.
  • Doxygen and release documentation (cmake/templates/conf.py.in, docs/sphinx/releases/whats_new_2_0_0.rst)

    • Sphinx now reconstructs Doxygen signatures from parameter XML.
    • New aliases and substitutions defined for documentation generation.
    • 2.0.0 release notes updated with release summary, breaking changes, and generated issue/PR lists.
  • Documentation reference alignment (multiple files under docs/sphinx/... and libs/full/runtime_components/include/hpx/runtime_components/new.hpp)

    • Updated links, literalinclude anchors, source paths, punctuation, and formatting.
    • Updated the runtime-components Doxygen title.

Changes: Release documentation and tooling

Layer / File(s) Summary
Release metadata
CMakeLists.txt, CITATION.cff, libs/core/version/src/version.cpp
The HPX version date and tag and citation title and date are updated. The source copyright year is also updated.
Release inventory generation
tools/generate_issue_pr_list.sh, docs/sphinx/contributing/release_procedure.rst
The script accepts base and release refs and an optional limit. It queries milestone data, reconciles PR candidates against local Git history, and formats the resulting lists. The release procedure documents the invocation and separate handling of cherry-picked or rebased PRs.
HPX 2.0.0 release notes and inventory
docs/sphinx/releases/whats_new_2_0_0.rst
The release notes describe requirements, changes, and breaking changes. They include issue and PR inventories and separately list seven incorporated PRs with merge commits outside the comparison revisions.
Doxygen signature and link configuration
cmake/templates/conf.py.in, libs/full/runtime_components/include/hpx/runtime_components/new.hpp
The Sphinx configuration reconstructs function signatures from Doxygen XML and adds stdexec and LCI substitutions. The runtime-components page declaration also lists hpx::local_new.
Sphinx requirements and reference updates
docs/sphinx/contributing/*, docs/sphinx/examples/termination_detection.rst, docs/sphinx/manual/*
Documentation updates module-build requirements, links, include markers and paths, and manual text and formatting.

AGAS RPC timeout handling

Layer / File(s) Summary
RPC timeout acceptance
libs/full/agas_base/src/rpc_timeout.cpp
set_rpc_timeout stores the timeout only when its converted millisecond count is nonzero. It returns false without changing the stored value when that count is zero.

ITTNotify workflow checkout

Layer / File(s) Summary
Pinned ITTNotify revision
.github/workflows/linux_debug_ittnotify.yml
The installation step checks out a pinned ittapi commit and adds a comment about the init-guard fix.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: Moderate · previous review 9c271

Release readiness remains moderate because some valid configurations can fail or be ignored, one test can hang, and regression coverage and published release metadata remain inaccurate.

Inline comments:
In `@libs/core/algorithms/tests/unit/container_algorithms/fold_range.cpp`:
- Line 369: Mark the ref_constructible_accumulator constructor taking int const&
as explicit, while leaving its parameter and behavior unchanged, so seed
construction requires direct initialization.

In `@libs/core/debugging/tests/regressions/hostname_print_helper_7520.cpp`:
- Around line 102-105: Remove the character whitelist assertion from the
regression test while retaining the non-empty check and cross-thread hostname
equality checks around get_hostname().

In `@libs/full/agas_base/src/detail/hosted_locality_namespace.cpp`:
- Around line 93-94: Update resolve_locality so the bootstrap path applies the
hpx.agas.rpc_timeout bound before waiting for endpoints_future, replacing the
unbounded is_ready spin with a bounded wait while preserving existing bootstrap
behavior and wait_or_handle_timeout handling.

In `@libs/full/agas_base/src/rpc_timeout.cpp`:
- Around line 21-27: Update set_rpc_timeout so positive sub-millisecond
durations are not silently stored as zero: preserve the timeout using
steady_duration resolution, or validate and reject unrepresentable values before
returning success. Ensure get_rpc_timeout reflects the accepted positive timeout
and retain the existing atomic storage behavior.

In
`@libs/full/runtime_components/tests/unit/components/reflect_async_distributed_test.cpp`:
- Line 92: Replace the unbounded while loop waiting for the posted callback in
the asynchronous distributed test with an HPX completion primitive that suspends
the thread and supports a bounded timeout. Ensure the test fails cleanly when
the callback is not completed or dispatch fails, while preserving the existing
callback completion behavior.

🟡 Minor · Accept every strictly positive timeout.

libs/full/agas_base/src/rpc_timeout.cpp:19-30
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Accept every strictly positive timeout. The public contract states that set_rpc_timeout succeeds for a strictly positive hpx::chrono::steady_duration. A positive duration below one millisecond is truncated to zero by duration_cast, so the timeout_ms.count() != 0 guard returns false and leaves the previous timeout unchanged. Preserve sub-millisecond precision, or change the public contract and documentation to require a whole-millisecond minimum at the API boundary.

set_rpc_timeout to accept every strictly positive timeout, including durations
below one millisecond; avoid rejecting values solely because duration_cast to
milliseconds produces zero, while preserving the existing stored-timeout
behavior and return contract.
🟡 Minor · Limit the sample rate to the supported int range.

CMakeLists.txt:1240
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Limit the sample rate to the supported int range.

2147483648 passes the positive-integer check and is emitted as #define HPX_TRACING_SAMPLE_RATE 2147483648. With Tracy enabled, std::atomic<int> sample_rate{HPX_TRACING_SAMPLE_RATE} causes a narrowing-conversion compile error. Reject values greater than INT_MAX during CMake configuration.

Exercise the Tracy configuration path. Configure with HPX_WITH_TRACY=ON and test the default value, a valid override such as 2, and invalid values such as 0 and 2147483648. Verify that valid values configure successfully and invalid values fail during configuration.

Sorry for the delay. Regenerated both lists against the 2.0.0 milestone and opened #7610 against release-2.0.X.

before now
closed issues 120 (#2235-#7539) 127 (#2235-#7591)
closed pull requests 687 (#5843-#7554) 722 (#5843-#7605)

The paragraph above the lists still quoted the old figures, so that is updated too. It also said "merged" where the query is is:closed, so that word changed with it.

Say the word when you are close to tagging and I will run it once more, since the milestone will keep moving until then.

The script was built entirely on hub, which GitHub archived in favour of
gh, and it exited immediately when hub was not on PATH. Rewrite the three
calls it made in terms of gh.

The GraphQL milestone lookup is gone: gh accepts a milestone title
directly, which is what the version parsed out of CMakeLists.txt already
is, so the number never has to be resolved. gh pr list has no --milestone
option, so the milestone is passed as a search qualifier there, which also
removes the need to print the milestone per PR and strip it back off with
sed. The separate jq dependency goes away with the GraphQL query, since gh
applies the filter itself.

Behaviour differences, all intentional:

- closed milestones are now considered as well, so the lists can be
  regenerated after a release is out. The old lookup only searched open
  milestones.
- a milestone that cannot be found is reported instead of silently
  producing two empty lists.
- errexit is enabled alongside pipefail. pipefail alone does not stop the
  script after a failed standalone command, so a failing issue query
  paired with a succeeding pull request query used to exit successfully
  and emit notes with the issue list missing. Both queries exit 0 on an
  empty result set when --json is used, so a milestone with nothing closed
  still produces the empty section rather than aborting.
- underscores that end a word are escaped. reStructuredText reads such a
  word as a hyperlink reference, so the title of #6500, "The test
  partitioned_vector_ doesn't finish in a very long time", rendered as a
  broken link. Underscores inside words are left alone.

Also correct the name of the script in the release procedure, which
referred to tools/generate_pr_issue_list.sh rather than
tools/generate_issue_pr_list.sh.

Verified against the 2.0.0 milestone: the generated lists parse with no
structural warnings under docutils, the counts match what the milestone
itself reports, and the lines match the formatting already used in the
existing release notes.

GitHub titles are not restricted to ASCII: the ones on this milestone
carry ellipses from GitHub truncating long titles, curly quotes, en and
em dashes, and in one case an emoji. The release notes are kept plain
ASCII, so map the punctuation that has an ASCII equivalent and drop
whatever is left, tidying up the whitespace an emoji leaves behind.

Requested by Hartmut in #7549. Doing it in the generator rather than in
the release notes keeps the next regeneration from undoing it.

docs/sphinx/releases/whats_new_2_0_0.rst was still the empty skeleton,
although master is already at 2.0.0 and the file is already listed in
docs/sphinx/releases.rst.

Fill it in with the detailed notes Hartmut wrote in #7549, covering the
language baseline, C++20 modules, the early C++26 adoption, the move to
stdexec for senders and receivers, the tag_invoke removal, the parcelport
and AGAS work, the new tracing infrastructure, collectives, the
supervision module, parallel algorithms, the scheduler, the build system
and the security fixes. Add the closed issue and closed pull request
lists generated from the 2.0.0 milestone: 120 issues and 687 pull
requests.

The external projects the notes mention are linked through the
substitutions the documentation already defines for Tracy, the Intel ITT
API, APEX, EVE and NVIDIA. stdexec and LCI had no substitution yet, so
add those two to the epilog in cmake/templates/conf.py.in, pointing at
the repositories the build system already fetches them from.

The prose follows the conventions of the surrounding documentation: the
|hpx| substitution rather than a bare HPX, "-" bullets, and plain ASCII
throughout. The generated lists are ASCII as well, as of the change to
tools/generate_issue_pr_list.sh on the branch of #7548.

Two adaptations to fit the file into the documentation as it stands:

- the title block is the one this file already had, so the hpx_2_0_0
  label and the entry in docs/sphinx/releases.rst keep working.
- a Breaking changes section is kept, as in every previous release notes
  file, summarising the four changes that require users to act and
  pointing at the detailed sections for each.

The lists will want regenerating once more shortly before the release,
since the milestone still has open items. The release date in the title
is deliberately left as TBD.

The Windows builds of jq end their output lines with CRLF. The carriage returns ended up in the PR numbers and merge commit hashes the script reads back, so git did not find any merge commit and every PR found through the milestone was silently omitted from the generated list.

The console unregisters a locality that force_disconnect() removes before
it records it as disconnected. A resolution in between that finds no cached
endpoints got bad_parameter, which the credit decrements don't ignore. The
locality is marked as disconnecting before it is unregistered, so report
that as locality_was_disconnected too. departed_locality_7384 now accepts
locality_was_disconnected for a resolution of the departed locality.
