To make GRASS releases more often and more predictable, here is GRASS next releases feature plan. This feature plan has to be filled by developers working on GRASS 6.4.

There is the release branch for 6.4.x - releasebranch_6_4. See details at ​tags and branches. A release branch is considered as "frozen", only bugfixes can be done.

To be released

GRASS 6.4.3

(Please backport with one commit (log message) for one change, not all at once, thanks. In general it is a good idea to wait a few days after release before beginning lots of changes, in case a "brown bag" release is needed. otherwise we'd need to cut a new branch from the tag for that. [to avoid brown-bag releases, last minute changes just before release are also discouraged])

GRASS 6.4.2

List of backports (modules) - done in r45933

  • v.net.allpairs, v.net.bridge, v.net.centrality, v.net.components, v.net.connectivity, v.net.distance, v.net.flow, v.net.spanningtree, v.net.timetable
  • v.kernel: r45407 (#1277) - done in r45955, r45956
  • r.univar, r3.univar: zonal support - done in r45941
  • pythonlib - done in r45934, r45935, r45936
  • v.out.ogr transactions + overwrite - done in r45943

Candidates for backporting:

  • r44869, r44817, r44890 (#1128) done in r46624, r44930, r45069, r45190, r45191, r45262 + r45235
  • wxGUI - done in r45931
  • wxGUI/vdigit - done in r45931
  • ps.map (I ask that this change is not backported until further notice. Only the minimal patch to backport the "b flag" should be considered. I'm still considering reverting parts of the rest. thanks, HB.)
  • quoting: (HB: each change requires testing before backport, tx)
  • gislib: (HB: do not backport, it's buggy: returns before logging errors to GIS_ERROR_LOG.)

Already released

GRASS 6.4.1

  • Any open Trac bugs which are blockers for 6.4.1 should be flagged as such in the bug report.
  • Look over old ​Gforge and ​RT bug trackers. Refile in trac as blockers if they are release-critical and close old reports with a link to the new one. Copy over all past discussion so it has context and history.

Candidates for backporting:

GRASS 6.4.0

Can do

Merge in replacements from Addons:

Modules to consider:

  • r.pack rewrite using method similar to r.convert ({{trac|84}}) + tar.gzip?
    • script written as r.pack2, but not for inclusion in 6.4.0 to ensure compatibility with future gr7 raster file layout, which is not yet defined.

Delayed:

  • r.viewshed: note that there are precision issues to be fixed by Laura, see #390

HTML manual pages polishing

The ​validator reports faulty pages. Correct pages are also needed for a future reST/Sphinx conversion

DONE:

  • gis.m
  • d.colorlist
  • d.extend
  • d.nviz
  • d.profile
  • d.rast.arrow
  • db.execute
  • db.select
  • g.mkfontcap
  • g.proj
  • d.what.rast

TODO list (you may use validator ​file upload, the dillo web browser also has a nice validator built in):

Wishlist

  • modify Makefile system to support translated HTML pages. Store translated HTML files in centralized directory with locale specific subdirs, file name is module name.
  • Make sqlite the default DB? <- done for 7
  • drop d.m display manager (as now almost unmaintained; there is gis.m and/or a python based GUI)
    • Some people still prefer it (see posts to grass-dev) and I will fix bugs in it, but not enhance/add new modules to it without good reason. So I don't see the need to drop it before the WxPython version is ready. It's not hurting us any keeping it. --Hamish
      • We should keep plain d.mon interface but why keep d.m, if gis.m has become really good? Probably we should clearly state, that d.m is UNMAINTAINED and OBSOLETE? -- MarisN 08:24, 16 February 2007 (CET)
      • --HB: ok, d.m man page updated.
  • raster maps: implement SQL based time series support (working code from Soeren in GRASS Addons)
  • Clean up Makefile system to support extension compilation and installation outside the GRASS installation and without the full GRASS source. Much like what GEM does, but without needing the module source setup and not limited to installing within the GRASS installation dir. This could also simplify GEM on the compilation side.
Updates to vector querying
  • v.select (query using a vector map):
    • add flags -p and -g for text output instead of creating a new map. It would report which map(s) and feature(s)/cat(s) meet the query criteria.
    • allow multiple maps to be selected. This would directly address Eric's question. If the output is a map, it would be the equivalent of v.patch on all queried vector elements.
    • add operators "contains" and "adjacent". Contains=all vector features whose nodes are completely inside a polygon (or inside or touching the boundary). Adjacent=all vector features who share a node/point or line/boundary with the selecting feature. Because GRASS is topologically correct, adjacency information is readily available. --HB: op="not" too please.
    • maybe change option names from ainput and binput to selector and selected or queried. This would have to wait until GRASS 7, of course. I find ainput and binput not very clear where used in other vector operations either (maybe I'm just dense).
      • --HB: input order counts, so named map options have a function.
  • v.what (query using coordinates):
    • add flags -p and -g for current behavior (-pg could be the default if we wanted to do this before GRASS 7)
    • add "output=" option to allow v.what to create a new map from the results of its query, like v.select does
    • allow multiple maps for input, as with the suggestion for v.select
    • allow coordinates to be read optionally as a line or area boundary (-l or -a?) instead of only as individual points.
  • add operators overlap, contains, adjacent.(This also would make possible interactive vector selection with a mouse drawn box or polygon from the GUI)
  • In other words, have v.select and v.what work the same except that v.select uses a vector map for querying and v.what uses a set of coordinate points.
  • v.overlay (boolean combination of maps):
    • drop the ainput and binput. Replace with just input. --HB: careful, order of maps can matter.
    • allow multiple maps to be entered into input, not just 2
    • deprecate v.patch because v.overlay with the OR operator replaces it. (If we wanted to do this before GRASS 7, we'd have to create a new module, maybe named v.combine or something like that because this changes the default behavior of v.overlay).
      • --HB: does it completely? I could be totally wrong, but my thought was that v.patch is very fast and does not attempt to clean (overlay) features, just lump them together in the file. Certainly for most tasks v.overlay should be the suggested route in the documentation.
In progress
  • Database connection for v.out.vtk: -- User:Huhabla 20:47, 14 August 2006 (CEST)
    • single column support for numerical data (int, float, double)
    • GRASSRGB column support (done for ps.map)
    • multiple column support for vector data
  • rewrite most of the g3d modules to fulfill the grass function naming convention --huhabla 20:47, 14 August 2006 (CEST)
  • BLAS/LAPACK updates (?)
  • Provide interactive environment on GRASS startup ​#521
  • 6.4.0RC1 (23 Dec 2008)
