Hi Gerd Quite possibly, or maybe there are limits in the device. More testing reveals that although my lists of cities and streets within them appear correctly in Find>Address, it doesn't find anything. Ticker On Sat, 2017-07-29 at 17:22 +0000, Gerd Petermann wrote:
Hi Tcker,
thanks for the patch. I seem to remember that the number of entries in mdr5 is also used elsewhere. Will have a closer look tomorrow.

Hi Gerd
It looks as if can simply write 1/2/3 bytes as have indicated in the magic field in the MDR header and I've changed it to do this. All seems OK.
Yes - I do misuse a City POI. But now, after having worked out how the MDR20 index works, I might be able to do what I want in a better way.
Attached is patch to write the correct number of bytes.
Regards Ticker

Hi Ticker,
yes, sounds plausible. The comment seems to say that we don't know how to handle so many cities. Why do you have so many cities. Do you "abuse" the corresponding POI for something?

Hi Gerd
I think I've found the problem:
/src/uk/me/parabola/imgfmt/app/mdr/Mdr5.java line 227
private void putLocalCityIndex(ImgFileWriter writer, int cityIndex) { if (localCitySize == 2) // 3 probably not possible in actual maps. writer.putChar((char) cityIndex); else writer.put((byte) cityIndex); }
There were more than 63335 cities in the failing map.

Hi Gerd
I've done a bit of investigation and debugging. It seems to be building the indexes with enough cities and streets. MDR20 is the suspect index.
I'm now experimenting with mkgmap / Display
With just the suspect map built in gmapsupp:
$ ... test.ExtractFile gmapsupp.img filter[] Copying . 65024 Copying MAKEGMAP.MPS 78 Copying 74440044.RGN 4154927 Copying 74440044.TRE 18772 Copying 74440044.LBL 2174485 Copying 74440044.NET 1626350 Copying 74440044.NOD 3566829 Copying 00007444.MDR 2979295 Copying 00007444.SRT 912

seems fine but
$ ... test.display.MdrCheck 00007444.MDR ---------- 00007444.MDR -------------------- EXTRA remaining {} # reading 74440044 mdr5 check Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 308736, Size: 70018 at java.util.ArrayList.rangeCheck(ArrayList.java:653) at java.util.ArrayList.get(ArrayList.java:429) at test.display.check.MapDetails.getCity(MapDetails.java:188) at test.display.MdrCheck.check5(MdrCheck.java:282) at test.display.MdrCheck.print(MdrCheck.java:87) at test.display.CommonDisplay.display(CommonDisplay.java:171) at test.display.CommonDisplay.display(CommonDisplay.java:196) at test.check.CommonCheck.runMain(CommonCheck.java:145) at test.display.MdrCheck.main(MdrCheck.java:1789) + exit
On another map from the split this runs OK, producing masses of output:
$ ... test.display.MdrCheck 00007429.MDR ---------- 00007429.MDR -------------------- EXTRA remaining {} # reading 74290047 ERROR: map 1: city 1: no name; index 1 mdr5 check 1 map1; ABBEY WOOD mapCity=2 reg=0 (LONDON) country=0 (UNITED KINGDOM^]GBR) ind20=0 rep=false 2 map1; ABRIDGE mapCity=3 reg=0 (ESSEX) country=0 (UNITED KINGDOM^]GBR) ind20=0 rep=false ... 87000 more lines ...
Do you think mkgmap:Display is finding a real problem and I should pursue this line, or could it be unreliable and this exception is due to it rather than the format of the index?
Thanks Ticker

With a particular split of 'british-isles', one map from the split causes the list of cities in the Find>Address function to be empty.
Maybe you have the same problem here which I described for road name search when road names contain special characters. In your case this would mean special characters in the citiy names. I suggest to add debug code in uk.me.parabola.imgfmt.app.mdr.Mdr5.writeSectData(ImgFileWriter writer) to print all city names which are written to the global index.
