mod_tile's Issues

mod_tile/extra/meta2tile does not comile for me

I get six error: dereferencing pointer to incomplete type
for lines 106, 113, 115, 156, 158, 159
the source was missing an include for metatile.h but has been subsequently updated with more functionality by the author prior to me figuring this out and the include is now in there so this is no longer an issue.

Support for OpenSuse

i tried to build the mod_tile as in the http://switch2osm.org/serving-tiles/manually-building-a-tile-server-14-04/

when i run make

the following error is coming

problem compiling

hi,

i'm compiling mod_tile under CentOS 6.
mapnik has been installed under /opt/osm.

$ locate mapnik-config
/opt/osm/bin/mapnik-config

./configure --with-boost=/opt/boost/ --with-libmapnik=/opt/osm/bin/mapnik-config
[..]
checking for mapnik-config... /opt/osm/bin/mapnik-config
checking for mapnik libraries... yes

yet it fails to compile. any idea? here's the output: http://pastebin.com/raw.php?i=fwtvAbBh

Host name warning at startup/reload

If something (AddTileConfig/LoadTileConfig) tries to add a tile config before the ServerName directive is seen (normal on Ubuntu where module config files are loaded before it is set) then you get this warning:

08:08:35 2013] [warn] Could not determine host name of server to configure tile-json request. Using localhost instead

Compiling with Mapnik master (3.x)

I'm trying to compile mod_tile for Mapnik 3.x, but compiling fails. I guess it has to do with the change to C++11, but I don't know enough about it to fix the problem myself.

• Current mapnik commit: mapnik/mapnik@37eaae3
• Current mod_tile commit: 681fbd4

Error Log: https://gist.github.com/plepe/7632178

32-bit instead of 8-bit PNG output

Rendering meta tiles with mod_tile/renderd always made my hillshade look ugly. This results in the 8 bit PNGs, which Mapnik doesn't rasterize nicely. The difference can be seen here:
8-bit:
32-bit:

Only two lines have to be changed in src/gen_tile.c:
Substitute both "png256" with "png"

There are two possible ways:

• Introduce option in user config file (/usr/local/etc/renderd.conf) for bit depth
• Improve Mapnik. Imagemagick can produce nice looking 8-bit PNGs for example by "convert -type Palette -quality 90 [...]"

Developer Documentation

I want to go into developing of mod-tile and renderd but can't find any developer documentation. Is there any and if so where to find it?

Incorrect ubuntu renderd.conf plugins_dir

Off of a clean install I got the error

An error occurred while loading the map layer 'default': Could not create datasource. No plugin found for type 'shape' (searched in: /usr/lib/mapnik/2.1/input

I traced this to an incorrect plugins_dir in renderd.conf and set plugins_dir=/usr/lib/mapnik/input but this should be set by default.

#2 (comment) suggests mapnik-config --input-plugins but a minimal install doesn't have mapnik-config which is part of libmapnik2-dev

Incompability with Postgis 2.1

I've got SQL error during pre-rendering process, because AsBinary and SetSRID functions has been renamed to ST_AsBinary and ST_SetSRID.

render_list default socket

The render_list default socket is reported as /tmp/osm-renderd but the default location in the renderd config file installed by packages is /var/run/renderd/renderd.sock. These should agree.

ModTileEnableTileThrottlingXForward=1 seems to block proxy requests

When configuring a tile server with ModTileEnableTileThrottlingXForward=1, I didn't get any answer when using X-Forwarded-for, but the same request without this header worked correctly. As soon as I changed the server configuration to ModTileEnableTileThrottlingXForward=0, the request worked correctly.

render_old ignores per-style timestamp files

Although store_file.c looks at both per-style timestamp files and a global one, render_old.c only looks at the global one...

"Failed to read cmd on fd" errors since mod_tile update on 2nd June

I have a fairly standard Ubuntu 14.04 based map server, set up as per http://wiki.openstreetmap.org/wiki/User:SomeoneElse/Ubuntu_1404_tileserver .

I installed it on 26th April, and everything worked as expected. On 2nd June I updated mod_tile from github and started seeing "Failed to read cmd on fd" errors in syslog:

Jun 9 12:20:52 ubuntuvm38 renderd[21354]: DEBUG: Got incoming request with protocol version 2

Jun 9 12:20:55 ubuntuvm38 renderd[21354]: DEBUG: Connection 0, fd 8 closed, now 5 left

This doesn't stop it working (all tiles are still being rendered as expected) but it does seem odd. Other server updates between 26th April and 2nd June include Ubuntu apt-get updates, a database reload from a new PBF file, but no changes to osm2pgsql style or (presumably) database columns etc.

http://forum.openstreetmap.org/viewtopic.php?id=25587

(from May 23rd) looks like it might be a similar issue.

planet-import-complete path for memcached storage

Where should I put planet-import-complete file when I use memcached storage for tiles?

mod_tile config parsing

Fetching tiles at /buildingclip does not work with this renderd.conf

[renderd]
stats_file=/var/run/renderd/renderd.stats
socketname=/var/run/renderd/renderd.sock
num_threads=4
tile_dir=/var/lib/mod_tile

[mapnik]
plugins_dir=/usr/lib/mapnik/input
font_dir=/usr/share/fonts/truetype/
font_dir_recurse=true

[default]
URI=/osm/
XML=/home/ubuntu/mapnik-stylesheets/osm.xml

[carto]
URI=/carto/
XML=/home/ubuntu/openstreetmap-carto/osm-carto.xml

[noamenity]
XML=/home/ubuntu/openstreetmap-carto/noamenity.xml

[nolandcover]
XML=/home/ubuntu/openstreetmap-carto/nolandcover.xml

[roadbbox]

[z14road]
XML=/home/ubuntu/openstreetmap-carto/z14_road.xml

[buildingclip]
URI=/buildingclip/
XML=/home/ubuntu/openstreetmap-carto/building_clip.xml

But it does work with this second renderd.conf

[renderd]
stats_file=/var/run/renderd/renderd.stats
socketname=/var/run/renderd/renderd.sock
num_threads=4
tile_dir=/var/lib/mod_tile

[mapnik]
plugins_dir=/usr/lib/mapnik/input
font_dir=/usr/share/fonts/truetype/
font_dir_recurse=true

[default]
URI=/osm/
XML=/home/ubuntu/mapnik-stylesheets/osm.xml

[carto]
URI=/carto/
XML=/home/ubuntu/openstreetmap-carto/osm-carto.xml

[buildingclip]
URI=/buildingclip/
XML=/home/ubuntu/openstreetmap-carto/building_clip.xml

[noamenity]
XML=/home/ubuntu/openstreetmap-carto/noamenity.xml

[nolandcover]
XML=/home/ubuntu/openstreetmap-carto/nolandcover.xml

[roadbbox]
XML=/home/ubuntu/openstreetmap-carto/roadbbox.xml

[z14road]
XML=/home/ubuntu/openstreetmap-carto/z14_road.xml

The only difference is that the buildingclip style has been moved up. Perhaps the styles with no URI parameter are screwing up the config parsing?

Both config files result in a line with [notice] Loading tile config buildingclip at /buildingclip/ for zooms 0 - 18 from tile directory /var/lib/mod_tile with extension .png and mime type image/png

Adding AddTileConfig /buildingclip/ buildingclip to the apache config for the first renderd.conf causes it to work.

How to add a new projection support?

Hi!
I want to use srs="+init=epsg:3395" in my Mapnik rendering toolchain. How to add this projection in renderd?

iniparser should be removed from mod_tile source tree

Since iniparser "is a is a free stand-alone ini file parsing library" (according to http://ndevilla.free.fr/iniparser/) it should b removed from mod_tile and mentioned as a dependency instead.

Unit / functional / integration testing of renderd

Currently mod_tile and renderd don't have a regression test suit. It is therefore unfortunately too easy to break something without noticing.

To try and continue to improve the quality of the software, it would be good to have a unit / functional / integration test suit.

This issue can be used to discuss the initial creation of such a test suit and how best to go about it.

render_list lat/lon tile range option

Hi!

I've read here gravitystorm/openstreetmap-carto#20 (comment) by @apmon :

The command to render was
"./render_list --all -f -m carto -s ~/tiles/rednderd.sock --min-lon 8.1 --max-lon 8.6 --min-lat 48.9 --max-lat 49.2 -z 14 -n 4"

But this option is missing in the current code. Strange… But anyway, good to have this feature.

Hi there,

The man-page for clock_gettime states, that linking with -lrt is required. So, after adding -lrt to LIBS in Makefile, compilation works fine.

Please do so too.

CORS support sends bogus Access-Control-Allow-Headers header

If the request does not have a Access-Control-Request-Headers header then the response will include:

because it has tried to format a null pointer into the response.

UTFGrid support

It would be great to support UTFGrid generation using renderd and mod_tile.

https://github.com/mapbox/utfgrid-spec

An example UTFGrid-enabled mapnik xml file is at https://gist.github.com/gravitystorm/5824793

I'd suggest that it's a per-layer option to also generate the UTFGrid at the same time as the png (or other raster) output, and expire them as a pair. However, I can see there being some (rare) usecases where you may wish to generate UTFGrids without a corresponding png output.

init_storage_backend: Value too large for defined data type

There is problem with stat function on big filesystem (XFS, 2TB+)

Possible fix (worked for me):

define __USE_LARGEFILE64

define _LARGEFILE_SOURCE

define _LARGEFILE64_SOURCE

define __USE_FILE_OFFSET64

before #include <sys/stat.h>

segfault error 4 in osm.input

Set max_size automatically based on configured thread count?

If renderd is configured to use more than 10 threads then the max_size parameter on each postgres layer in the stylesheet needs to be increased. It would be nice if renderd could do this automatically by iterating over the layers in the stylesheet and updating the max_size value based on the thread count.

Virtual host stops mod_tile?

Hello,

I installed OSM via switch2osm package installer on Ubuntu 12.4.04. When I add a subdomain with a2ensite and reload, the tile (0/0/0.png for instance) goes 404. If I a2dissite and reload it's back up again.

How can I fix this?

render_list verbosity

render_list has no options to control the verbosity, but always outputs debug options. An option to only display the results or to display no output except errors would be helpful.

Can't use semicolons (and therefore html entities) in per-style attribution

The default attribution can be interpreted as html, e.g. when shown in tilejson output

https://github.com/openstreetmap/mod_tile/blob/master/mod_tile.h#L32

It can be overwritten per-style in renderd.conf

https://github.com/openstreetmap/mod_tile/blob/master/renderd.conf#L38

However, this doesn't work if you have any semicolons in your override string, e.g. for ampersands, copyright entities or similar. The role of semicolons in .ini files seems to be implementation-specific as to whether they are a comment delineator only at the start of the line, only when preceded by whitespace, or at any point during the line. Additionally, escape sequences (typically backslash, e.g. ; ) are implementation-specific. At the moment, we have an anywhere-no-escape parser.

Perhaps we need a different ini parser, or a different configuration file format.

Does "tile_dir" option really work?

Hi!
I have no success with the "tile_dir" option. Seems that it doesn't work for me. So I need to put a symlinks in /var/lib/mod_tile directory to specify the desired tiles location. Maybe I missed something? Help me understand.

Specifying two different XMLs for one map for various zooms

Hello again!
Is it possible to specify two different XML stylesheets for one map at different zoom levels? I tried this config:

[map]
URI=/map/
XML=/path/to/xml/xml1.xml
MINZOOM=10
MAXZOOM=18

[map2]
URI=/map/
XML=/path/to/xml/xml2.xml
MINZOOM=0
MAXZOOM=9

But with no success. Looks like URI=/map/ doesn't work. Maybe I've misunderstood the function of URI?

render_* tools, not waiting end of threads as before

Hi all,

Rendering tools like render_list or render_old do not wait the end of threads before ending. Looks like it finished at end of enqueing instead of rendering.
I need to know when rendering finished to work on new tiles (eg meta2tile)
Not sure if it's a bug or a new feature.
If new feature, could we have a option to command line in order to wait until rendering finished ?

Regards,
Bruno.

renderd doesn't respect the 'buffer-size' property

Hi.
renderd doesn't respect Mapnik XML's <Map buffer-size="xxx"> property. This property is important to help avoid cut labels.
I have tried several values (buffer-size="128", buffer-size="256", buffer-size="512"), but with no difference for a result.

Apache's error.log: tile storage hook

Hello,
I have a mapserver running in Debian squeeze with Mapnik 2.0, Mod_tile and renderd. It works fine, but in the apache's log appears the error:

initialising file storage backend debug messages

UTFGrid support for mod_tile

Trying to get mod_tile producing UTF8Grids. Wondering if anyone else has looked at this. Apparently the fix would be in mapnik itself. Some notes on this from @springmeyer below.

The reason renderd does not support tile end points for interactivity/grids is that Mapnik support is partially in C++ and partially in the bindings (python or JavaScript). It ended up this way because to leverage the json support in each of those languages and not implement the full json encoding for utf8grids in C++. But in doing so, renderd needs to implement that json encoding on its own, which has not happened yet and likely shouldn't since ideally Mapnik would just do this in C++ to save the duplicative work.

The grid_renderer builds up an image like array of feature ids. Then that needs to be turned into json. The code to do it is is already in c++ actually but writes to a c++ boost python object. Instead it would need to write to a string that could be parseable as json. The bindings code is mapnik/bindings/python/python_grid_utils.hpp. We don't actually need a json encoder and the intermediate objects it would likely require.

I don't know about to workaround this. Passing --tag=CC fixes the problem, but its unclear to me how to pass it to libtool

Don't use apr_global_mutex to guard storage backend initialisation

Commit 2c53891 introduced locking around memory allocation for an array containing pointers to the storage backends, as apache's memory pool functions aren't thread safe. It used apr_global_mutex, but I think apr_global_mutex not only synchronizes between threads, but also between process which isn't necessary for the storage backend memory allocation. Instead presumably apr_thread_mutex is what we want.

I need to verify this before committing the change, hence this reminder ticket.
