* Discussion with Vaclav Petras on current state of python packaging, build, and testing framework and coverage, Windows porting improvements, and future plans. Planning for the week. Lead to PRs addressing Windows blockers: [https://github.com/OSGeo/grass/pull/3850 #3850] and [https://github.com/OSGeo/grass/pull/3853 #3853], which I tested on my fork combined with my changes highlighting the bugs.
* Reviewing of PRs, managing CI during the sprint (restarting transient failures, finding inefficiencies, queueing jobs before and after active periods).
* Maintaining code quality CI and pre-commit. Example: Flake8 fails with Python 3.12 in pre-commit, as it is way outdated, harming contributions of the sprint's participants. Bumping to a new version has other failures and dependent changes needed. Related PRs include: [https://github.com/OSGeo/grass/pull/3808 #3808], [https://github.com/OSGeo/grass/pull/3831 #3831], [https://github.com/OSGeo/grass/pull/3833 #3833], [https://github.com/OSGeo/grass/pull/3840 #3840], [https://github.com/OSGeo/grass/pull/3814 #3814], [https://github.com/OSGeo/grass/pull/3799 #3799], [https://github.com/OSGeo/grass/pull/3834 #3834], [https://github.com/OSGeo/grass/pull/3815 #3815], [https://github.com/OSGeo/grass/pull/3820 #3820], [https://github.com/OSGeo/grass/pull/3818, #3818], [https://github.com/OSGeo/grass/pull/3813 #3813], [https://github.com/OSGeo/grass/pull/3855 #3855], [https://github.com/OSGeo/grass/pull/3817 #3817], [https://github.com/OSGeo/grass/pull/3812 #3812], [https://github.com/OSGeo/grass/pull/3859 #3859], [https://github.com/OSGeo/grass/pull/3860 #3860], [https://github.com/OSGeo/grass/pull/3861 #3861], [https://github.com/OSGeo/grass/pull/3841 #3841]
* Help Markus debugging Dockerfile builds. Reviewed docker-related PRs, improved docker builds, upgrade base images. (PRs: [https://github.com/OSGeo/grass/pull/3802 #3802], [https://github.com/OSGeo/grass/pull/3807 #3807], [https://github.com/OSGeo/grass/pull/3810 #3810], [https://github.com/OSGeo/grass/pull/3828 #3828], [https://github.com/OSGeo/grass/pull/3819 #3819], [https://github.com/OSGeo/grass/pull/3830 #3830], [https://github.com/OSGeo/grass/pull/3797 #3797], [https://github.com/OSGeo/grass/pull/3787 #3787], [https://github.com/OSGeo/grass/pull/3773 #3773], [https://github.com/OSGeo/grass/pull/3822 #3822], [https://github.com/OSGeo/grass/pull/3728 #3728])
* Helped multiple times Alen Mangafić with usage and building custom Docker images with different versions of PDAL.
* Designing and drafting the integration of docker build caching to improve build times whilst keeping risk of using cached old dependencies. [https://github.com/OSGeo/grass/pull/3821 #3821]
* With Vaclav Petras: reviewing backportable PRs, and designing the requirements and it's implementation of a automated backport solution with GitHub actions. Prioritized to work on the implementation after the sprint, as other features affecting productivity during the sprint should be worked on. Edit: implementation started on [https://github.com/echoix/grass/tree/backport-automation a branch of my fork]
* With Vaclav Petras: Discussing release notes generation improvements, deciding on new labels and classification, adjusting and improving titles regexes. Designed a process to validate PR that PR titles are classified correctly automatically, to greatly simplify future releases. This lead to Vaclav creating the validation function in [https://github.com/OSGeo/grass/pull/3824 PR #3824]. Implementation of validation workflow on PR creation and title changes will follow. PRs related to these decisions also include: [https://github.com/OSGeo/grass/pull/3823 #3823], [https://github.com/OSGeo/grass/pull/3829 #3829]
* Clarifying our supported languages standard support with Vaclav Petras and when changes should be made, leading to reduction of C/C++ CI usage in [https://github.com/OSGeo/grass/pull/3846 #3846]. Postponed checking of newer C++23 until Ubuntu 24.04 builds with newest GCC toolchain are included in CI.
* Helping Alen Mangafić with a local build to run alongside jupyter and conda environment.
* Reviewing Chung-Yuan Liang's PR, then assisting him multiple times with git operations, argparse, and unittest-related problems when programming. Sample of resulting PRs: [https://github.com/OSGeo/grass/pull/3835 #3835]
* Review and ajust repository's configuration to prevent some noticed problems, including pull request title/commit details (with Markus) and ruleset permissions related to branch creation (with Vaclav).
* PR title validation workflow implemented: [https://github.com/OSGeo/grass/pull/3877 #3877]
* Debug and investigate pytest timeout failures of [https://github.com/OSGeo/grass/pull/3879 #3879] that that same PR was supposed to prevent. The most probable explanation requires changing the multiprocessing startup method from fork to spawn, that also requires the code to be pickle-able. Alternative solution to avoid this requires changes of blocked and unmerged PRs that I worked to unblock. Unblocking these is also required to run pytest on macOS and Windows, and for a future python 3.14 on Linux too.
* Finish debugging porting Travis CI to Ubuntu 22.04 (Jammy) to unblock other PRs. Needed to fix some errors from -Wdeprecated-non-prototype to make Travis pass with the new -Werror flag. PR: [https://github.com/OSGeo/grass/pull/3002 #3002]
* Windows test failures due to external web content used for g.extension tests not being available for 8.5 on winGRASS yet. [https://github.com/OSGeo/grass/issues/3893 #3893]

=== Vaclav Petras ===

* PR reviews (a lot)
* Work on RC1 (release notes, automatic generators)
* Venue organizing and hosting
* Review of media posts

Related PRs include: [https://github.com/OSGeo/grass/pull/3808 #3808], [https://github.com/OSGeo/grass/pull/3831 #3831], [https://github.com/OSGeo/grass/pull/3833 #3833], [https://github.com/OSGeo/grass/pull/3840 #3840], [https://github.com/OSGeo/grass/pull/3814 #3814], [https://github.com/OSGeo/grass/pull/3799 #3799], [https://github.com/OSGeo/grass/pull/3834 #3834], [https://github.com/OSGeo/grass/pull/3815 #3815], [https://github.com/OSGeo/grass/pull/3820 #3820], [https://github.com/OSGeo/grass/pull/3818, #3818], [https://github.com/OSGeo/grass/pull/3813 #3813], [https://github.com/OSGeo/grass/pull/3855 #3855], [https://github.com/OSGeo/grass/pull/3817 #3817], [https://github.com/OSGeo/grass/pull/3812 #3812], [https://github.com/OSGeo/grass/pull/3859 #3859], [https://github.com/OSGeo/grass/pull/3860 #3860], [https://github.com/OSGeo/grass/pull/3861 #3861], [https://github.com/OSGeo/grass/pull/3841 #3841]
* Help Markus debugging Dockerfile builds. Reviewed docker-related PRs, improved docker builds, upgrade base images. (PRs: [https://github.com/OSGeo/grass/pull/3802 #3802], [https://github.com/OSGeo/grass/pull/3807 #3807], [https://github.com/OSGeo/grass/pull/3810 #3810], [https://github.com/OSGeo/grass/pull/3828 #3828], [https://github.com/OSGeo/grass/pull/3819 #3819], [https://github.com/OSGeo/grass/pull/3830 #3830], [https://github.com/OSGeo/grass/pull/3797 #3797], [https://github.com/OSGeo/grass/pull/3787 #3787], [https://github.com/OSGeo/grass/pull/3773 #3773], [https://github.com/OSGeo/grass/pull/3822 #3822], [https://github.com/OSGeo/grass/pull/3728 #3728])
* Helped multiple times Alen Mangafić with usage and building custom Docker images with different versions of PDAL.
* Designing and drafting the integration of docker build caching to improve build times whilst keeping risk of using cached old dependencies. [https://github.com/OSGeo/grass/pull/3821 #3821]
* With Vaclav Petras: reviewing backportable PRs, and designing the requirements and it's implementation of a automated backport solution with GitHub actions. Prioritized to work on the implementation after the sprint, as other features affecting productivity during the sprint should be worked on. Edit: implementation started on [https://github.com/echoix/grass/tree/backport-automation a branch of my fork]
* With Vaclav Petras: Discussing release notes generation improvements, deciding on new labels and classification, adjusting and improving titles regexes. Designed a process to validate PR that PR titles are classified correctly automatically, to greatly simplify future releases. This lead to Vaclav creating the validation function in [https://github.com/OSGeo/grass/pull/3824 PR #3824]. Implementation of validation workflow on PR creation and title changes will follow. PRs related to these decisions also include: [https://github.com/OSGeo/grass/pull/3823 #3823], [https://github.com/OSGeo/grass/pull/3829 #3829]
* Clarifying our supported languages standard support with Vaclav Petras and when changes should be made, leading to reduction of C/C++ CI usage in [https://github.com/OSGeo/grass/pull/3846 #3846]. Postponed checking of newer C++23 until Ubuntu 24.04 builds with newest GCC toolchain are included in CI.
* Helping Alen Mangafić with a local build to run alongside jupyter and conda environment.
* Reviewing Chung-Yuan Liang's PR, then assisting him multiple times with git operations, argparse, and unittest-related problems when programming. Sample of resulting PRs: [https://github.com/OSGeo/grass/pull/3835 #3835]
* Review and ajust repository's configuration to prevent some noticed problems, including pull request title/commit details (with Markus) and ruleset permissions related to branch creation (with Vaclav).
* PR title validation workflow implemented: [https://github.com/OSGeo/grass/pull/3877 #3877]
* Debug and investigate pytest timeout failures of [https://github.com/OSGeo/grass/pull/3879 #3879] that that same PR was supposed to prevent. The most probable explanation requires changing the multiprocessing startup method from fork to spawn, that also requires the code to be pickle-able. Alternative solution to avoid this requires changes of blocked and unmerged PRs that I worked to unblock. Unblocking these is also required to run pytest on macOS and Windows, and for a future python 3.14 on Linux too.
* Finish debugging porting Travis CI to Ubuntu 22.04 (Jammy) to unblock other PRs. Needed to fix some errors from -Wdeprecated-non-prototype to make Travis pass with the new -Werror flag. PR: [https://github.com/OSGeo/grass/pull/3002 #3002]
* Windows test failures due to external web content used for g.extension tests not being available for 8.5 on winGRASS yet. [https://github.com/OSGeo/grass/issues/3893 #3893]

=== Vaclav Petras ===

{{toc|right}}
The ''GRASS GIS Community Meeting'' for contributors and developers will be happening from '''June 14 to June 19, 2024''' in Prague, Czechia.

[[File:Prague-Community-Meeting-2023-crop.jpg|500px|frameless|center]]

== Sponsor us! ==

We welcome financial contributions to support the meeting and we are looking for sponsors to cover costs such as meals or to help reducing travel and accommodation expenses for GRASS developers who volunteer their time. If you are interested in sponsoring the GRASS Community Meeting, please go to:

::: '''[https://opencollective.com/osgeo/projects/grass/contribute OpenCollective]'''

Any surplus at the end of the event will be used for future activities of the GRASS GIS project such as the [[Student Grants|Student Grant program]].

This GRASS Community Meeting is a great occasion for you to support the development of GRASS. With your contribution you'll enable more developers to meet. Community meetings are important opportunities for developers to discuss, fix bugs, plan the direction for the project and work on new features. The developers and other contributors or their employers are donating their valuable time, so it would be great if funding can be made available from within the community to cover out-of-pocket expenses. All of the work that takes place at the community meeting will be directly contributed back into the GRASS project to the benefit of everyone who uses it. Note that while we have our general plan, we can't accept any earmarked donations, i.e., we can't make any promises for a specific work to be done, please contact specific developers or support commercial providers for that.

We are grateful to the following sponsors for their support and commitment!

* U.S. National Science Foundation, award 2303651. (Travel for 5 participants and their time, event venue.)

[[File:NSF Official logo.png|none|left|200px|alt=Logo of US NSF|U.S. National Science Foundation]]

* In-kind contributions will be acknowledged here.
* Personal time and/or financial contributions will be acknowledged here.

== Purpose ==

The ''GRASS GIS Community Meeting'' is a great occasion for folks to support the development by actively contributing to the project in different ways. These include source code updates, documentation (manuals, wiki, tutorials), translations, website improvements or likewise. The community meeting is also a get-together where supporters, contributors, power users and developers make decisions and tackle larger problems related to the project, discuss and collaboratively resolve bugs, plan the direction for the project and work on new features. We welcome people committed to improving the GRASS GIS project and the interfaces to QGIS, GDAL, PostGIS, R, OGC Services and others.

In this meeting, building on momentum from the 40th birthday meeting, we will continue the revisions of the maintenance processes and infrastructure - a process which highly benefits from the current maintainers being in one place (and time zone). Topics which require highly synchronous collaboration will be included such as Markdown documentation and CMake build transitions. Other contributors are expected to enhance existing tools and their documentation. A [https://grass.osgeo.org/news/2023_08_13_grass_community_meeting_prague_june_2023_report/ press release] gives an overview of last year's event.

We do require participants to work on GRASS GIS or connections to other projects. However, we leave them the freedom to work on what they think is the best contribution to the project given their skills and time available.
