[mkgmap-dev] Please try and report results of Huffman compression

Sun Jan 16 17:14:35 GMT 2022

Hi Arndt,

I don't see anything wrong in the diagnostic data. This seems to be a very small map. Please post a link to the tile(s) so that I can try to reproduce the crash here.

Gerd

Hi Gerd,

i forget to activate the diagnostic function. I build the maps new, but it takes time. Fabrik and NRWplusare running now......

Here are the information from "Fabrik", the other map send i later.

Hi.
https://files.mkgmap.org.uk/detail/544

ALLVARLIG (MultiPolygonRelation): folder/77700046.osm.pbf: Internal error:
Failed to render MultiPolygonRelation 2970267
that was with --latin1

mkgmap version 4839 works well.

Hi all,
during the last weeks Ticker and I decoded Garmin's String compression of
the global index for the PC (the *_mdr.img) . In the mdr2 branch I've coded
support for that in mkgmap and I think its ready for a first beta test.
It works with codepages 1250 ..1258 or 65001.
I've no idea how the 2-byte pages work, but Garmin seems to support that,
too. Maybe I'll work on this later.
The branch version produces around 200 lines of diagnostic output to show
what happens when compression is enabled. This will be changed to debug
level later.
The encoding is enabled by default, special option --x-no-mdr15-compression
can be used to turn it off.
Note that the size of the *_mdr.img file will be smaller (which is esp.
intersting for those who get close to the 2G limit) Note also that a zipped
*_mdr.img can and will be larger since zip cannot remove as much
redundancy. Note also that this branch includes the changes from the
faster-mp branch and introduces a few changes which are relavant for
--lower-case maps.
How to test?
Install the map in MapSource and check if you see any unexpected characters
in the result lists or maybe even crashes while searching. If so, please
try the same input files with the --x-no-mdr15-compression to verify if
this is caused by compression or maybe other changes.
Please don't yet publish the maps, but let me know if you see anything
unexpected. Some changes reg. lower-case in this branch are still
experimental.
The binary is here:
https://www.mkgmap.org.uk/download/mkgmap-mdr2-r4865.zip
If you see errors which are caused by compression, please attach the
diagnostic output.
@Ticker: Please review the source.
