Intermittent errors from the GDAL driver starting in 3.2.0

mojodna commented 9 years ago

I'm getting intermittent errors from the GDAL driver that eventually result in segfaults and aborts (I'm going to try to put together a repro for this tomorrow):

Error: /home/ubuntu/.../data/WA/n47.5w122.3.tif, band 1: IReadBlock failed at X offset 2, Y offset 5

The files that cause problems may be consistent. This also appears between 3.1.6 and 3.2.0 and makes me wonder about "Mapnik GDAL plugin now keeps datasets open for the lifetime of the datasource (rather than per featureset)" (from the change log).

springmeyer commented 9 years ago

yeah. I also wonder if https://github.com/mapnik/mapnik/pull/2686 is the cause. Another potential idea though: are you using any other gdal version besides what the node-Mapnik binaries are bringing in?

mojodna commented 9 years ago

Not unless it's picking up libgdal1h installed via apt. Would it?

springmeyer commented 9 years ago

Not unless it's picking up libgdal1h installed via apt

The only way that would happen is if LD_LIBRARY_PATH is set to point at /usr/lib

mojodna commented 9 years ago

These remain intermittent, but don't appear to segfault after https://github.com/mapbox/tilelive-mapnik/commit/37a96814534910b4b7df48ce2fad119edd7defe4

brianreavis commented 9 years ago

I'm also getting these intermittently (node-mapnik 3.3.0). Like @mojodna said, consistent repro is proving to be difficult. If there's anything else I can provide or ways to help, let me know!

ERROR 1: TIFFFillStrip:Read error at scanline 192; got 432 bytes, expected 8192
ERROR 1: TIFFReadEncodedStrip() failed.
ERROR 1: 13_745_382.tif, band 1: IReadBlock failed at X offset 0, Y offset 7
ERROR 1: GetBlockRef failed at X block offset 0, Y block offset 7

Not all GetBlockRef, IReadBlock errors are accompanied by the TIFFFillStrip,TIFFReadEncodedStrip error.

springmeyer commented 9 years ago

Not sure what is causing this yet. Also not replicated myself. So, I'll just collect what we know:

@mojodna thinks this started happening in 3.2.0 and did not happen in the previous release 3.1.6
okay, so what changed between those releases?
- the binaries changed from being built against gdal 1.11.1 to 1.11.2
- the binaries changed from being built against libtiff trunk at https://github.com/vadz/libtiff/commit/14bca0edd838b7dd8128960c7f12dd240411ba0b to being built against libtiff 4.0.4beta
- the binaries starting using mapnik with gdal.input that keeps datasources open: https://github.com/mapnik/mapnik/pull/2686

So, any of the above changes could be related. My hunch is that https://github.com/rouault/mapnik/commit/5551cae0be1ab56910ecae016a39eb670cf431b1 is the most likely. We don't want to revert it (keeping datasets open - as long as they are not simulataneously shared between two threads - is the right thing and helps perf). But it would be the first thing I'd try to revert if I had a reproducible testcase - just to see if it fixes the problem.

springmeyer commented 9 years ago

/cc @rouault - do you have ideas of what might cause the above error TIFFFillStrip:Read error at scanline 192; got 432 bytes, expected 8192 and or have suggestions about what things to try for debugging?

rouault commented 9 years ago

@springmeyer Are you absolutely sure that a dataset is read by no more than one thread simultaneously ? Otherwise, is it a scenario where GDAL is used in read-only mode ? Because if not, in a scenario where you would have N threads doing GDAL read and 1 thread doing GDAL writes (or read/writes), a known (well, maybe not so known) deficiency of the global block cache design is that when the cache is filled and a new block must be read, a block that is going to be discarded may be "dirty" (ie has been written) and is going to be flushed to disk. So you can potentially have thread T1 that reads in dataset D1 but must flush a dirty block of dataset D2. If at the same time, thread T2 is reading or writing D2, chaos might occur and the errors you got are very likely.

springmeyer commented 9 years ago

@rouault - yes, datasets are opened as read-only with GDALOpen (https://github.com/mapnik/mapnik/blob/master/plugins/input/gdal/gdal_datasource.cpp#L87) and we ensure that only one thread is accessing at a time by pooling the mapnik.Map (which holds a pointer to the mapnik::gdal_datasource holding the GDALDataset*.

rouault commented 9 years ago

Hum, if someone manages to reproduce it sometimes, an idea would be to run the test under GDB and define a break-point on CPLErrorV (with a debug build of GDAL). This will be triggered by the above errors. And then inspect that state. An explanation for "ERROR 1: TIFFFillStrip:Read error at scanline 192; got 432 bytes, expected 8192" would be that the file pointer is not at its expected location and thus not enough bytes are read. But I can't see how this could happen (expected if 2 threads were messing with the same GDALDataset object). It should be checked that there's no use of GDALOpenShared() too from the "main" thread.

springmeyer commented 9 years ago

Thanks @rouault - will look for a chance to do this. In this case I'm building libtiff separately - so I presume I'll need that in debug too? Or no? Also, correctly there should be no use of GDALOpenShared in this case.

brianreavis commented 9 years ago

Another case of "I don't completely know if this is related, but maybe it'll help?":

ERROR 1: TIFFFieldWithTag:Internal error, unknown tag 0x0 ERROR 1: TIFFFetchStripThing:Incompatible type for "unknown tagname"

Got this to show up today on a big tile rendering run. It's strange that the only crashes we're getting are all TIFF related. Although I suppose it could be a problem with rasters in general, it just so happens that TIFF is the only raster format we're using.

mojodna commented 9 years ago

(It's the only format I'm using.)

rouault commented 9 years ago

All this really sounds like multi-threading issue. Are TIFF directly used, or through a VRT ? If from a VRT, that could be the issue, since VRT use OpenShared() internally.

brianreavis commented 9 years ago

@rouault We're using them through a VRT (cc @brandonreavis)

mojodna commented 9 years ago

VRT here as well.

flippmoke commented 9 years ago

@rouault assuming they are still using a global cache, one cache block can be cleared by another while it is still in use, even in read only?

rouault commented 9 years ago

It's not an issue with the block cache but really concurrent use of the underlying TIFF dataset handle.

The issue is that the VRT driver implements a strategy of defered opening for underlying sources, and when opening of the underlying source is really needed, it uses shared mode. This addresses the case of VRT made of hundreds or more of sources that would exhaust the limit of file descriptors and for which the initial opening time could be really slow. Imagine we have a VRT that points to a single TIFF and 2 worker threads. In the main thread, we open 2 GDAL Datasets for this VRT. Up to now, no TIFF opened. In the main thread, we now read data from each dataset handle. Then the TIFF is opened, and since it is opened from the same thread, the same underlying GDAL dataset is reused. After that, we dispatch the 2 VRT datasets on the 2 worker threads, and bang, we have the underlying TIFF dataset concurrently used.

The easiest fix I see would be add a shared="0" attribute to the <SourceFilename> element (similarly to what is available in OGR VRT) and modify the VRT driver accordingly to open in non-shared mode. That assumes that your VRTs are made of a reasonably small number of sources.

rouault commented 9 years ago

The issue you ran into is actually described in the "Multi-threading issues" at the end of http://gdal.org/gdal_vrttut.html

mojodna commented 9 years ago

That assumes that your VRTs are made of a reasonably small number of sources.

My scenario (the one that's triggering this) immediately violates that, as the VRT contains 15654 sources (due to the way that the source data was provided).

rouault commented 9 years ago

Thinking more and reviewing the code, I think the GDALDatasetPool mechanism (that limits the number of "real" GDAL datasets opened) could be improved to implement a non-shared strategy (if instructed to do so through the shared="0" attribute), thus allowing VRTs with arbitrary number of sources.

rouault commented 9 years ago

I've created https://trac.osgeo.org/gdal/ticket/5992 and committed a fix in GDAL trunk (2.1dev). I'll backport in GDAL 2.0 branch too if it works OK. Backporting to 1.11 might be inpractical because it would require breaking the ABI of the VRT driver, unless I find a nasty trick.

rouault commented 9 years ago

Backported in 2.0 branch. Edit: the name of the configuration option is VRT_SHARED_SOURCE, to set to 0, to force opening of existing VRT files that haven't shared='0' attribute in non-shared mode

springmeyer commented 9 years ago

@rouault - incredible work, thank you. Since I've not personally replicated I'm hoping that @mojodna or @brianreavis might be able to test your work or share with me a reproducible testcase. @mojodna or @brianreavis - let me know if you are able to put together gdal/mapnik/node-mapnik enough to test @rouault's fix yourself or if you'd like an assist from me by creating testing binaries against gdal-latest.

mojodna commented 9 years ago

I just managed to get a full-fledged segfault, which appears to confirm the diagnosis here. I'll see about building my own mapnik against @rouault's patch (to be clear, which branch should I build GDAL from?).

@springmeyer can you point me at build instructions?

@mojodna @springmeyer You can either use the official GDAL 2.0.0 release, the https://svn.osgeo.org/gdal/branches/2.0 branch or the https://svn.osgeo.org/gdal/trunk (2.1dev, which has now a different C++ ABI than 2.0). You need in addition to either change your VRTs to include a shared="0" attribute in each element, or define the configuration option / environmenet variable VRT_SHARED_SOURCE to 0. I also realize that when disabling shared source, some optimizations will be disabled, notably if you make a VRT of a RGB dataset (or a mosaic of RGB datasets), up to now the same GDAL dataset was used for the 3 R,G,B bands. With shared=0, there will be a GDAL dataset for each band, which will likely negatively impact performance if the TIFF have INTERLEAVE=PIXEL (if they have INTERLEAVE=BAND that shouldn't matter much). A potential improvement could be for the VRT driver to realize that it can share the same dataset for the R,G,B component.

flippmoke commented 9 years ago

@mojodna I have been trying to make a test to reproduce this fault, do you have one?

mojodna commented 9 years ago

@flippmoke No consistent repro, but I'm still seeing it a bunch. Can you point me at instructions on building node-mapnik from source where I can introduce @rouault's patch?

springmeyer commented 9 years ago

@mojodna I think it would be ideal to put effort into helping us reproduce. Because:

I'm aware your setup is somewhat custom (fuse filesystem). I really want to reduce the testcase to something that others can replicate because I'm keen to fix this but also don't want to spin cycles maybe trying to fix the wrong thing.
if the patch does not fix this then the next step would be consider rolling back the "keep open" part of https://github.com/mapnik/mapnik/pull/2686. I really don't want to do that, however, without proof it is needed.

springmeyer commented 9 years ago

@mojodna shoot me an email if you want to discuss any details.

mojodna commented 9 years ago

This is actually occurring without the FUSE piece, which is both good and bad ;-)

I'm fully booked today, but can probably spend some time on this tomorrow. I'd like to get a version of node-mapnik w/ GDAL 2.0 and logging enabled. The behavior described above (multiple threads accessing the same TIFF within a large VRT in a specific order) matches the failures. The ordering seems to result in happy behavior, the warnings, or even full-blown segfaults.

rouault commented 9 years ago

@springmeyer I guess this is going to be difficult to have a fully reproducable test case as this is really a race condition. I could perhaps cook up a simple patch to the TIFF driver that would trigger an assertion in case of concurrent access (setting/checking a "bHasAlreadyEnteredThatMethod" boolean), more often than with the normal production code. Also thinking that setting GDAL_CACHEMAX=0 might also increase the chances for the race condition.

flippmoke commented 9 years ago

@mojodna I attempted to access a large several different VRTs from the an increasing number of threads on mapnik 3.1.6, 3.2.0, and 3.3.0 and none of them were able to reproduce the results for me. I will try with GDAL_CACHEMAX=0 here in a second though. Thanks @rouault

flippmoke commented 9 years ago

GDAL_CACHEMAX=0 seemed to have no effect. I am still not able to reproduce @mojodna. @springmeyer pointed out that this could be related to #445 so I will be testing the resulting output against multiple threads to see if any images are being corrupted.

flippmoke commented 9 years ago

I checked to make sure that multi-threading was not causing any issues with the rendering causing strange artifacts so checked if the resulting images were always the same as ones rendered from one thread.I have been unable still to reproduce any of the multithreaded failures mentioned.

mojodna commented 9 years ago

@springmeyer / @flippmoke help me get a version of node-mapnik compiled against GDAL 2.0 and with logging enabled.

(It's probably a link to a doc somewhere, but I don't know where to look.)

I doubt I can create a consistent repro, but given that it's still happening for me, I'd like to see if @rouault's suggestion makes it go away.

mojodna commented 9 years ago

Ok, I seemingly got it built, but before I can even test the GDAL bits, I'm seeing transparent images and corresponding libpng warning: Application built with libpng-1.5.18 but running with 1.6.17 errors (despite having set PNG_INCLUDES and PNG_LIBS to /usr/local/{include,lib} when building mapnik).

springmeyer commented 9 years ago

@mojodna - do you have two sets of libpng headers on your system? Does ldd should both libmapnik and libgdal are linked to the same png?

mojodna commented 9 years ago

Quite likely. libpng is also installed from homebrew.

Err, /usr/local/lib/libgdal.20.dylib doesn't exist. So much for trying to avoid polluting /usr/local... Rebuilding mapnik.

mojodna commented 9 years ago

Again: how do you configure your local development environments?

springmeyer commented 9 years ago

@mojodna currently I'm building mapnik/gdal with https://github.com/mapnik/mapnik-packaging and then node-mapnik against the product of that via this script https://github.com/mapnik/node-mapnik/blob/master/scripts/build_against_sdk.sh. The Mapnik-packaging scripts have some key lines like https://github.com/mapnik/mapnik-packaging/blob/master/build.sh#L215 and https://github.com/mapnik/mapnik-packaging/blob/master/osx/settings.sh#L384-L386 to avoid clashing system libs. I'm planning to move over to use mason package (https://github.com/mapbox/mason) but that is still a work in progress.

mojodna commented 9 years ago

This is what I've figured out from looking at the Travis config so far:

$ bash # since build_mapnik exits otherwise
$ source ./build.sh
$ build_mapnik

(I'm attempting to build on OS X 10.10, fwiw)

(It now crashes fairly reliably with VRT_SHARED_SOURCE=0.)

Without VRT_SHARED_SOURCE, this error message crops up pretty frequently:

ERROR 1: VRTSourcedRasterBand::IRasterIO() called recursively on the same band. It looks like the VRT is referencing itself.

The VRTs in question (there are 4 layers) point to a set of per-state VRTs that each contain TIFFs; I've confirmed that there are no circular references.

Interesting: when recreating the VRTs to point directly at the TIFFs, I can't reproduce (yet), with or without VRT_SHARED_SOURCE (using GDAL 2.0).

@mojodna OK I've managed to build a simple test case to reproduce the crash with the 2 levels of VRT in non-shared mode. Correction pushed in GDAL trunk and 2.0 branch. See https://trac.osgeo.org/gdal/ticket/6017. This is not related to multi-threading use. Hopefully with the fix, your use case shouldn't crash anymore...

rouault commented 9 years ago

And regarding the "ERROR 1: VRTSourcedRasterBand::IRasterIO() called recursively on the same band" message when not using VRT_SHARED_SOURCE, this is expected. There's a counter in VRTSourcedRasterBand::IRasterIO() that is used to detect potential cycles in VRT chains. Here you don't have cycles, but the same VRT dataset handle is used concurrently (due to shared open mode), which looks like a recursive call to the code that detects it. This is another symptom similar to random libtiff errors with VRTs that reference TIFF in shared open mode.

mojodna commented 9 years ago

@rouault: should I consider "ERROR 1: VRTSourcedRasterBand::IRasterIO() called recursively on the same band" a diagnostic warning (when I know there are no cycles) or something more severe?

(I intend to use the VRT w/ 1 level at this point in any case.)

Awesome re: crash repro! I'll rebuild soon w/ new bits and give it a shot.
