Todays topics[edit]
- Meet and greet 5 minutes before meeting (audio testing).
Discourse[edit]
- General question about the acceptance.
- We like it.
- Continue to no longer actively advertise the mailing-lists.
Octave 6.3.0[edit]
- 6.3 Release Checklist
- Bug #60620: octave-cli crashes when interacting with Java libraries
- Not blocking release.
- jwe takes a look.
- ABI breaking minor release? https://octave.discourse.group/t/more-frequent-minor-releases/1127
- Not blocking release.
- Do not increase major version number, only API version.
Octave releases[edit]
- Keep the current versioning scheme https://hg.savannah.gnu.org/hgweb/octave/file/1077d7c87fcc/etc/HACKING.md#l301.
- Only one major release per year.
- Should include new features.
- Developer time is limited, more not doable.
- More frequent minor releases, not 100% perfect, promise to try to keep API/ABI compatibility.
- Better error than crash on API/ABI changes.
- It seems this problem occurred with development versions of Octave.
- No mercy for developers: they hopefully know what they are doing, have to cope with breaking changes.
- Normally the API version of oct files is checked, thus it should not have crashed and rather have warned.
- Contrary with development version, even after breaking changes, the API is only incremented once for the release. This might have caused the trouble.
- It seems this problem occurred with development versions of Octave.
- Octave on MS Windows, Linux, macOS usually has somehow a compiler available (unlike Matlab on MS Windows), thus recompiling the oct files is annoying, but possible.
GitHub Actions[edit]
- Markus gave a small presentation of this project.
- https://github.com/gnu-octave/octave/actions (need to be member of the https://github.com/gnu-octave organization, just ask on Discourse https://octave.discourse.group/t/github-gitlab-organization-for-gnu-octave/178).
- Not 100% perfect yet, but already in a good shape.
- CodeQL static code analysis
- Help with macOS wanted
QScintilla signal/slot problem[edit]
- Bug #60469
- On MS Windows only for QScintilla the "safer" signal/slot changes seem to not work.
- Revert it until the problem is identified.
Previous topics[edit]
- The following items were not discussed. Just some links to progress on those items are displayed.
MXE Octave branches[edit]
- Which changes should go on which branch?
- "default": everything new
- "release": conservative updates
Buildbots[edit]
- Find out how to trigger a build on changes in two repositories?
GitHub[edit]
- Markus added a folder ".github" to the Octave main repo?
- How are the experiences so far? 😉
String class strategy[edit]
- Strategy for transition to string class syntax (incompatible to current double-quoted character vectors in Octave)?
- Issue treatment of escape characters (first interpreted when Xprintf is applied).
- Suggestion to implement an initial string class at one point
- Many existing Octave code (packages) might break.
- In the transition time using
- Octave .oct-config files to manage how double quoted strings are treated
- Implement convertStringsToChars and solve issue per function basis (Matlab compatible, probably straight forward, but many changes).
- Initial implementation by Andrew Janke
Classdef[edit]
- Wish to define classdef classes from C++ "nicely" (currently only from m-files comfortable usable).
- This would also help implementing the string class.
C++17[edit]
General consensus was to stay with C++11 until a "killer application" shows up that justifies changing to a newer standard.
