MdrSummary fix and improvements
by Ticker Berkin 02 Feb '22

Hi Gerd Patch attached to fix MdrSummary readHeaderLen, cope with different hdr lengths more clearly and improve output. I've found I can now split my old "City Navigator Europe NT" map and look at the MDR, which includes sections 30/31, 32/33, 34, 37 & 38 codePage=1252 id1=18 id2=1 unk=0x0011 hdrLen=708 Compressed strings flag=0x0000 MDR 1 NR=265 (000109) RS=4 magic=0x00000002 2 NR=0 (000000) RS=2 magic=0x00000000 3 NR=0 (000000) RS=2 magic=0x00000000 4 NR=0 (000000) RS=3 magic=0x00000000 MDR 5 NR=633075 (09a8f3) RS=15 magic=0x00003e51 MDR 6 NR=181613 (02c56d) RS=4 magic=0x00000001 7 NR=0 (000000) RS=9 magic=0x00001ae2 8 DS=0 (00000000) magic=0x00000000 MDR 9 NR=1 (000001) RS=4 magic=0x00000000 MDR 10 DS=1607528 (00188768) magic=0x00000000 MDR 11 NR=401882 (0621da) RS=13 magic=0x00000575 12 DS=0 (00000000) magic=0x00000000 13 DS=0 (00000000) magic=0x00000000 14 DS=0 (00000000) magic=0x00000000 15 DS=0 (00000000) magic=0x00000000 16 DS=0 (00000000) magic=0x00000000 MDR 17 DS=2868654 (002bc5ae) magic=0x00000000 18 DS=0 (00000000) magic=0x00000000 19 DS=0 (00000000) magic=0x00000000 MDR 20 DS=65810719 (03ec311f) magic=0x00060000 21 DS=0 (00000000) magic=0x00000000 MDR 22 NR=8006434(7a2b22) RS=9 magic=0x0004035e 23 NR=0 (000000) RS=9 magic=0x00000000 MDR 24 NR=15516 (003c9c) RS=7 magic=0x00000000 MDR 25 NR=649642 (09e9aa) RS=3 magic=0x00000000 26 DS=0 (00000000) magic=0x00000000 27 DS=0 (00000000) magic=0x00000000 28 NR=0 (000000) RS=13 magic=0x00000000 MDR 29 NR=1452 (0005ac) RS=20 magic=0x000003f6 MDR 30 NR=637 (00027d) RS=4 magic=0x00000000 MDR 31 DS=3983 (00000f8f) magic=0x00000000 MDR 32 NR=566 (000236) RS=4 magic=0x00000000 MDR 33 DS=3039 (00000bdf) magic=0x00000000 MDR 34 NR=12 (00000c) RS=3 magic=0x00000000 35 NR=0 (000000) RS=3 magic=0x00000000 36 NR=0 (000000) RS=4 magic=0x00000000 MDR 37 NR=2194204(217b1c) RS=23 magic=0x00000000 MDR 38 NR=17120 (0042e0) RS=40 magic=0x00000033 39 NR=0 (000000) RS=22 magic=0x00000000 40 DS=0 (00000000) magic=0x00000000 Ticker

Commit r4889: Improve interpretation of TRE7 data (extended types offsets) not written by mkgmap
by svn commit 01 Feb '22

01 Feb '22

Version mkgmap-r4889 was committed by gerd on Tue, 01 Feb 2022 Improve interpretation of TRE7 data (extended types offsets) not written by mkgmap - check magic value in TRE7 to find out which offsets are set (mkgmap write 0x607 which means all offsets are valid). GPXSee does something similar in TREFile::readExtEntry() and Steve already assumed this according to the comment for magic 0x0607 in TreHeader. - handle the case that the number of records in TRE7 is smaller than the number of subdivisions. In this case the subdivisions with the lowest resolution are probably without extended types. Should have no effect on mkgmap output but allows RgnDisplay to handle more maps. http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4889

Commit r4888: improve handling of data inside GMP file
by svn commit 01 Feb '22

01 Feb '22

Version mkgmap-r4888 was committed by gerd on Tue, 01 Feb 2022 improve handling of data inside GMP file - probably all uses of reader.position(xxx) where xxx is a constant must be changed to reader.position(reader.getGMPOffset() + xxx) - add more code to handle unexpected data in TRE7 It seems when subdiv record lengths > 13 there isn't extended offset data for all subdivisions. http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4888

Commit r4887: Fix assertions to actually check the calculated sizes.
by svn commit 01 Feb '22

01 Feb '22

Version mkgmap-r4887 was committed by gerd on Tue, 01 Feb 2022 Fix assertions to actually check the calculated sizes. The code to read TRE7 data (extended types offsets) only works for maps where tre7.recsize() <= 13. Maps can have larger record sizes and the current logic in TreFileReader.readExtTypeOffsetsRecords() fails with them. No problem for mkgmaps own maps but RgnDisplay may show nonsense with those maps http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=4887
