v20.8.0

GeoDms 20.8.0 is a large engineering release. The headline is an object-ownership refactor — the TreeItem / data-item family moved from intrusive reference-counting onto standard std::shared_ptr / std::weak_ptr, closing a class of teardown hangs, exit leaks and use-after-frees. Alongside it are a broad build & compile-time modernization (precompiled headers, std::format, a large boost reduction down to a handful of header-only libraries, a three-DLL merge), a Qt 6.11 upgrade, a big Linux/GCC warning cleanup, expanded Python bindings, and a set of view, operator and storage fixes.

The sections below cover everything since 20.3.0 — the 20.4 / 20.5 / 20.6 / 20.7 builds were internal and not published as GitHub releases.

Builds are provided at the same source revision in three flavors:

Flavor Platform Asset
.m Windows x64 (MSBuild) GeoDms20.8.0.m-Setup-x64.exe
.c Windows x64 (CMake) GeoDms20.8.0.c-Setup-x64.exe
.l Linux x64 (WSL / Ubuntu 24.04) GeoDms20.8.0.l-linux-x64.deb (+ .tar.gz)

🧬 Object-ownership refactor (internals)

  • The TreeItem / data-item family was migrated from intrusive SharedPtr / WeakPtr onto standard std::shared_ptr / std::weak_ptr, with an explicit parent-owns-child model and non-owning std::weak_ptr back-references.
  • Fixed a class of ownership bugs surfaced by the migration: several teardown drain hangs, memory leaks reported at exit, cache-unit liveness use-after-frees, move-assignment lock leaks (ItemWriteLock / DataWriteLock / DataReadLockAtom), and interest-at-destruction leaks that hung GUI close.
  • Fixed a GUI exit deadlock: open map views and value-info windows are now destroyed before the shutdown drain waits on the item interest they hold (previously their deletion was deferred past the drain, hanging test-script and app-exit teardown — reproducibly so on Linux).
  • Debug unit tests now exit cleanly; headless Debug runs surface asserts and leak dumps without modal abort() dialog stalls.

🏗️ Build & compile-time modernization

  • Precompiled headers enabled for the 8 DLL projects.
  • boost::format → std::format; broad boost reduction (random / locale / tuple / mpl / core / preprocessor → std / native); boost_thread eliminated (Spirit parsing serialized behind a single mutex); boost::signals2 replaced by a ~100-line synchronous Signal<> (drops ~1100 transitive headers from 29 view-DLL translation units).
  • The boost dependency narrowed to 11 header-only libraries actually used; GeoDMS links zero compiled boost, and the installed boost runtime DLLs went from 37 to 15 (the remainder are CGAL / asio package dependencies).
  • rtc + sym + tic merged into a single DLL (DmRtc / Rtc.dll); source tree flattened accordingly.
  • clc: the four largest translation units split per value-type for faster, more parallel builds.
  • On-demand MSVC /analyze (PREfast) pass (analyze.bat); fixed the intermittent vcpkg runtime-DLL deploy gap for good (both a stray machine-wide vcpkg integration and an IncrementalClean bookkeeping asymmetry that reaped the GDAL/GEOS/PROJ runtime DLLs on certain build sequences).

🐧 Linux / GCC

  • Warning cleanup from ~67k down to a few hundred, fixing a handful of latent bugs along the way (a delete[] of void*, a pointer-vs-literal comparison, a 16-bit truncation, a 1 << 63 shift overflow, an always-false IsInTrans()).
  • Self-contained Linux package — the .l setup bundles the Qt6 runtime with an $ORIGIN rpath, so the GUI runs without a system Qt6 install.
  • Fixed an exit-time SIGABRT after GDAL write sessions (the GDAL cleanup atexit hook is now Windows-only; on Linux it ran after GDAL's own teardown).
  • Missing-#include and link fixes that GCC surfaces but MSVC hides.

🖥️ Qt & Python

  • Qt upgraded to 6.11.1.
  • Python bindings: primary-data accessors, InMemoryConfig functions, an example and binding test scripts; the CMake build now ships Python 3.13.

🗺️ View & interaction

  • #515: overview zoom-out limited to the background / world extent.
  • #1151: drag sliders widened to 8 px (was 5 px).
  • #1150: table resize works after Toggle Rows/Cols; honest, non-sticky resize cursors; added untoggled row-height resize.
  • #1149: statistics copy-to-clipboard now starts with an Item name <path> row (and fixes a ReplaceChar infinite loop).

🔧 Operators, storage & fixes

  • #1152: items whose storage turns out to hold no primary data now fail with a clear error instead of lingering non-ready and non-failed.
  • #411: the table-view export button opens the Export Primary Data dialog (adds XML format) and reports export failures.
  • #367: internal file:// UNC encoding is converted to native paths at the GDAL / cfs boundaries.
  • #1146 / #1148: actionable errors on export-meta self-reference instead of recursing; force a 0 class-break when signed data straddles zero.
  • #1124: MetaInfo sidecar diverted to <stem>.meta.<ext> when it would collide with the dataset; GML classified as non-updatable.
  • Removed long-obsolete operators (format / unprefixed boost::polygon / non-DPoint GEOS).
