vips dzsave core dumps #46
Comments

Sometimes it just says CORE DUMPED but actually doesn't dump anything, I also tried different tile sizes: The one tile size that tends to actually do the job is 512px: |

Hi, looks like it's a problem with google layout. If I compile with debugging I see: $ vips dzsave wtc.jpg x --layout google
** VIPS:ERROR:type.c:164:vips_area_unref: assertion failed: (area->count > 0)
Aborted (core dumped)I'll investigate tomorrow. |

This commit fixes it for me: The problem was that google maps output copies the background property for each tile it makes, and these tiles are made and freed in a background thread. There need to be locks on the reference counts used to manage array property lifetimes. Thanks for reporting this nasty thing. |

Hello, |
|
I haev recompiled, then ldconfig, then restarted the virtual machine and it is still there I will terminate the virtual machine and create new one where I will compile on a clean slate and will report back. |
|
Oh dear. I'll download Leica-1.scn and try with that tomorrow. This is the openslide test image I guess? Does it work if you try with a regular jpg image? J |

I haven't tried with regular image I will be using with digital slides, so I am testing it with slides. I just generated half a million files (altogether 700MB of them) in less than 9 minutes! 👍 I still can't get it to work where I need to use it though :( Right now what I do is hunt down libraries it requires one by one using |

Glad it's working! There are so many ways to deploy, it's hard to know what would be best for you without knowing a lot of detail. The simplest is just to build vips on each machine, or perhaps have a single VM image you send out to the servers. Next is to use jhbuild to make a private tree, then zip that up and copy to the target machines. If this is Debian or Redhat, you can make your own repository, put a private vips binary in there and deploy with apt or redcarpet. SuSE has something similar I think. It's not really my field though. There's a sysadmin stackoverflow now, perhaps they have a guide? |

Hi, we are having trouble installing libvips on CentOS 6, Any chance you will put a new tarball on the website soon? This is what we are getting: and then this when compiling from source (the old 7.30.6 from web): I finally feel quite comfortable getting VIPS to work on Debian based distributions, but this is Amazon Linux which is very close to Cent OS 6 and I have noc lue what is going on, it's like a different world :( . |

I've opened a new issue for this one: https://github.com/jcupitt/libvips/issues/47 It'll make it easier for other people to find if they have the same problem. |
Hi, vips dzsave seemingly randomly hangs (well it tends to happen when I request 256px tiles).
I compiled libvips from this commit 418427b
Before that I compiled openslide from this commit openslide/openslide@3b1e205
Is the following of any use to you?
