While running autogen.sh on a blank mageia 5 install, and after installing all the packages that autogen.sh was complaining about, the script finally complete, albeit with a complaint about a missing gio-sharp and gtk-sharp-beans:

Package gtk-sharp-beans-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk-sharp-beans-2.0.pc'
to the PKG_CONFIG_PATH environment variable

Those two packages should cause the autogen.sh script to fail.

When building on Debian (sid, using mono 4.2.1.102) a host of build errors are produced:

   CSC: error CS0518: The predefined type `System.Object' is not defined or imported
   CSC: error CS0518: The predefined type `System.(lots-of-other-types)' is not defined or imported
   ...

These errors can be avoided by setting TargetFrameworkVersion to v4.5 in the relevant .csproj files. The affected files are:

/external/flickrnet/FlickrNet/FlickrNet.csproj
/external/mono-addins/Mono.Addins/Mono.Addins.csproj
/external/mono-addins/Mono.Addins.Setup/Mono.Addins.Setup.csproj
/external/mono-addins/Mono.Addins.Gui/Mono.Addins.Gui.csproj

As it is not clear as to whether this error only occurs on Debian, only on mono 4.2.1 or whether it is limited by some other environmental factor I did not make a pull request.

When I for example maximise F-Spot window (this is important as it effects the performance of F-Spot great amount) in Gnome 3 X11 environment in Fedora 26, and then grab sidebar's separator and make sidebar larger and smaller I get awfully lot of following kind of messages to terminal:

F-Spot performance is quite poor constantly. Similar terminal output to the above come out when I move any F-Spot UI element, click any buttons, click any images, transform any images, and so on. And while F-Spot doesn't crash, its speed can come down a lot to the point of chocking and almost hungs up completely but then comes back to it's stuttering self after few seconds.

Some items like moving the sidebar separator in browsing mode are clearly worse than others. Scrolling through the photo library by dragging scrollbar is quite bad as well and it can take many seconds for it to move to dragged spot and then even longer for images to show up on the browse view as thumbnails.

Hell, even the about dialog takes few seconds to pop-up and get drawn...

When I import my jpgs at some point I get very many warnings of the same kind:

...
[Warn 23:52:28.957] Metadata of file file:///home/david/Fotos/2007/05/05/DSC_0004.JPG may be corrupt, refusing to write to it, falling back to XMP sidecar.

...

What do you suggest me doing for fixing it?

When minimum versions of dependencies are updated, it would be really helpful if any associated mention in README is also updated. It looks like at minimum mono, liblcms, dbus-sharp, and dbus-sharp-glib need updating.

Steps to reproduce:

1. clean F-Spot instance (otherwise, you should logout first when you get the flickr export dialog)
2. Pick a file, select "Export to Flickr"
3. on the dialog, click "Authorize"
   Expected: browser opens, you are prompted to give permission to f-spot to use the flickr API on your behalf, and once done you can go back to F-Spot to Complete authentication
   Actual: Redirect in the browser gives you the flickr homepage, 'Complete authentication' button in F-Spot doesn't log you in.

Root cause: 'Frob' authentication to the Flickr API is deprecated in favor of OAuth.

line 964:  Mono: DllImport searching in: 'libgtk-x11-2.0.so.0' ('libgtk-x11-2.0.so.0').

This issue is caused by the fact that in the f-spot bin folder (and then in the runtime directory), gtk-sharp-beans.dll is copied without its gtk-sharp-beans.dll.config. This happens with versions of gtk-sharp-beans prior to 2.14, where the DLLs were installed in the GAC, and some symlinks were missing from /usr/lib/mono/gtk-sharp-beans-2.0, that f-spot uses to copy the gtk-sharp-beans locally.

Required gtk-sharp-beans version needs to be bumped to 2.14

I've been trying to track down a crash importing photos, but I found every time I try to scoll to a specific date range, I get what seems to be the same crash. If I'm in browse view, it doesn't matter if I use the scroll bar, the mouse wheel, or up- or down-arrow to get the the offending date or image. In filmstip view, it also crashes when I get to near a particular image/date. I can select from the time-line either before or after, but if I select the right time - crash.
The following is one line I've seen repeatedly, which seems really strange to me, and I hope will help track this down:
System.Exception: Something is horribly wrong, this should never happen: no default version!

scroll_crash.txt
scroll_crash2.txt

Note I've looked at every image within the area that causes the crash, and I don't see anything special about any one of them.

Are you seeing this?

cf. Gnome Bugzilla's https://bugzilla.gnome.org/show_bug.cgi?id=724386

I would have written this as a comment on #32 but I guess this needs quite some maximum attention from the devs now that the development of this program started again. The website for f-spot is now NSFW and I don't think you'd like people to access this repo just to have a look on it outside working hours (or even at work, who am I to judge?).

I think you guys would rather have it removed from the README.md, but I don't mind you keeping it.

( ͡° ͜ʖ ͡°)

While using dbus-sharp 0.7.0 and dbus-sharp-glib 0.5.0, the autogen.sh passes. However, the make step fails with the following error.

/usr/lib/mono/4.5/Microsoft.Common.targets:  warning : Reference 'dbus-sharp, Version=2.0.0.0, Culture=neutral, PublicKeyToken=5675b0c3093115b5' not resolved

Since dbus-sharp jumped to API 2.0 from version 0.8, and dbus-sharp-glib from 0.6, the autogen.sh script and README need to be updated to reflect the updated version requirement.

Raised on Ubuntu as https://bugs.launchpad.net/ubuntu/+source/f-spot/+bug/1335877

On June 27th, Flickr decided to switch all their API URLs to HTTPS-only. The FlickrNet API, prior to version 3.13, was using HTTP only to connect to the Flickr API. As a result, the Flickr Export is broken.

F-Spot sees but fails to import Nikon NEF format RAW images (see attached screenshot).

Thanks.

lcms1 is depracated and likely to be completely removed from Gentoo, and is one of the reasons given for removing f-spot itself from their tree. I've started looking at this, and will provide a patch if I succeed, but I suspect it will be a bit beyond me to actually complete.

Currently, the checkbox on the import dialog to delete images after import only applies to images actually imported. If the import directory contains duplicates of images previously imported, and the user has selected to check for duplicates, then only those images actually imported (i.e., not duplicates) will be deleted from the source directory.

I sometimes do NOT check the delete after import, especially if I absolutely want to confirm the import before deleting. I know I can manually go the the import directory and delete the files, but I would like to be able to check the delete box, repeat the import, and have f-spot delete the files. I am NOT requesting that the default behaviour be changed, but that some option be presented such as "Also delete images not imported because they were detected as duplicates." It might also be less confusing if this checkbox only appears if the main "delete after import" and "detect duplicates" are both checked.

Not a bug, but notes from my recent build from git head on a newly installed Ubuntu 18.04 in a VirtualBox on a Gentoo host. Probably most useful in updated requirements in README. It's pretty abbreviated, so ask if any explanation or expansion is needed.

Notes.txt

If you rotate an image when its in editing mode it doesn't appear rotated. Going back to the browsing mode shows the image as rotated.

When ./autogen.sh is run without --enable-tests the following make still requires Moq to build f-spot.

this should point to the existing higher res icon somehow.

Using commit 9e21938 with the package here:

https://launchpad.net/~christopher-hoskin/+archive/ubuntu/f-spot

Steps to reproduce:

Start F-Spot, select one or more images. From the 'Photo' menu, choose 'Export To...' Choose any of the options, e.g. 'Folder..' F-spot then quits unexpectedly.

(I've seen this on both Gentoo and Arch) The source includes f-spot-question-mark, but it doesn't get installed anywhere, leading to a null reference exception. Manually putting this file in /usr/share/f-spot/icons/hicolor/status eliminates the exception. (Oddly, I don't actually see that icon displayed anywhere on screen, so I'm not sure in my case why it's trying to load/dislay it.) The actual error is:

I just tried a fresh compile, and it failed looking for gnome-icon-theme. It took me a while to track this down, but that package was removed from Gentoo in April with the comment that Gnome is now using Adwaita instead. I'm not sure at what point other distros will also drop it (artix linux still has it available.) but configure should allow for either.

When opening the import dialog the combo box labeled "Choose Import source..." correctly shows connected cameras, SD cards, DAV mounts, etc.
When the dialog is opened a second time, all connected cameras, SD cards, etc. are listed twice. Some sources are even listed with different names and icons (e.g., 'user on server' vs 'user@server' for DAV mounts), although they point to the exact same gvfs path.

The code uses gio-sharp to list all mounts which itself calls g_volume_monitor_get_mounts to enumerate the mounts. This method returns the duplicates when the dialog is opened a second time. The behavior is somehow triggered by GLib.Idle.Add in ImportDialog.cs. Simply enumerating the mounts twice via GLib.VolumeMonitor.Mounts does not cause the duplicate entries.
Once the duplicate entries are there, they don't seem to disapear on subsequent enumerations.

I'm not sure if this is a bug in gio-sharp or in glib2.

When trying to import the following photo

this is happening

I tried to dig to the issue but failed.

Have a directory with at least 10 images which are each larger than 2MBs in size, open "Import Photos..." window, toggle off the "Copy files to the Photos folder", choose the directory and click "import" button and F-Spot crashes. It leaves following behind:

I'm using Fedora 26 at the moment. I can provide you more information if you need any.

It looks like it is MIT and gpl2?

Review code, possible just delete extension? This should be MIT only

Steps to reproduce

• git clone https://github.com/mono/f-spot.git (used repository tree as of May 4th when writing this issue)
• run autogen.sh and fail to find all requirements
• add Mono deb repository to Ubuntu
• frantically keep installing packages until autogen.sh doesn't complain
• finally, end up with a successful run of autogen.sh and you get Run 'make' to build F-Spot. - yay!
• make

make

Running f-spot (compiled from git head) produces many errors like:

although the trace differs widely. Based on googling, I'm not sure if this is a bug in f-spot (attempt to double free?) or a problem in an underlying library. Right now, I can only find one report: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1264368

There is an upstream but: https://bugzilla.gnome.org/show_bug.cgi?id=721369 but I can't quite follow all the finger pointing.

This one is not related to f-spot, but does have some interesting (relevant?) comments: http://stackoverflow.com/questions/23199699/glib-critical-source-id-xxx-was-not-found-when-attempting-to-remove-it

It is obviously not critical, but would be nice to solve, as it clutters up debugging output for other problems.

With the latest master I get this strange error when I try to import fotos to the collection. Any idea what it is or how I can fix that?

• Can't import images (PhotoStore CreateFrom is commented out)
• PhotoVersion stuff is messed up currently, right now it just creates them, not sure it is actually storing them. Also, there is an InsertVersion that might not be necessary?
• Imported photos don't show up in the photo browser
• Tag icon stuff is messed up. Review the whole thing.

It is possible to reorganize tags by drag/drop.
In this way, user can move one tag to be re-parented under a different parent.

While in process of drag, there are GUI indications that dragged tag can be dropped in between two tags (see screenshot). This would make it possible to reorder sibling tags manually.

Sibling tags are ordered according to property Tag::SortPriority, and then alphabetically in case Tag::SortPriority values are the same. Initial value of Tag::SortPriority property for all user created tags is 0.

The problem is that Tag::SortPriority property is never updated after drop, so no matter where item is dropped it is always sorted alphabetically among all sibling tags (all have value 0).

Only default tags (Favorites, Hidden, People, ...) have this property set because they are created programatically by application.

There are couple of possible courses of action:

Remove possibility to reorder tags using drag/drop

By removing following code segment from TagSelectionWidget::HandleDragMotion, it will no longer be possible to drop tag between two rows:

// Tags can be dropped before, after, or into another tag
if (args.Context.Targets[0].Name == "application/x-fspot-tags") {
  Gdk.Rectangle rect = GetCellArea(path, Columns[0]);
  double vpos = Math.Abs(rect.Y - args.Y) / (double)rect.Height;
  if (vpos < 0.2) {
    position = TreeViewDropPosition.Before;
  } else if (vpos > 0.8) {
    position = TreeViewDropPosition.After;
  }
}

All tags will be alphabetically ordered.

Implement only manually ordered tags

• When new tag is added it is automatically added as the last child of node and its' Tag::SortPriority property is set accordingly.
• During drag/drop and tag deletion Tag::SortPriority properties of all sibling tags are updated so that they always reflect current position of a tag.

In this scenario name of the tag will never have an effect on item position because Tag::SortPriority properties of all siblings will be unique.

Implement full support for reordering of tags

Tag::SortPriority property should be updated on drop.
I haven't tested this behavior of Tag tree. We might end up with behavior that is confusing to user because of complex interaction of Tag::SortPriority property that can be any integer number.

Couple of discussion points:

• Do we always keep Tag::SortPriority as incremental number? If we allow manual sorting, we might consider exposing this value to user so he might assign some specific value to one tag. That way he can have one tag with Tag::SortPriority value of 1000 that will always keep last position.
• How to restore alphabetical ordering once manual order was created?
• What is Tag::SortPriority value of a newly created tag? Currently it is 0 and all tags with same value are sorted alphabetically among themselves.
• If we drag any item in a group with Tag::SortPriority == 0, we should update Tag::SortPriority properties on all of them. In case of screenshot we would need to update Tag::SortPriority of all tags in order to keep Item 3 in between Item 1 and Item 2.

Possible solution

• New tags are created with Tag::SortPriority = 0 in case it is the first tag in group or if all other tags have Tag::SortPriority == 0.
• If there already exists a tag in a group with Tag::SortPriority !=0, than new tag will go to last place and it's Tag::SortPriority property will be set accordingly
• Whenever a tag is deleted or reordered, we update Tag::SortPriority properties on all sibling tags to keep them reflect their position in a group

In this case we would have alphabetically sorted tags if user didn't do any manual ordering, and manual sorting in case any reorder has been done inside a tag group.

Personal take on the problem

I would prefer to avoid last solution.
Combination of both alphabetical sorting and manual reordering might get confusing to users. I think we should choose either alphabetical sorting or manual ordering for all user created tags.

On distributions like Fedora or Mageia, Mono installations come without root certificates installed, and those may not necessarily be synced from the local root certificates as a post installation step either.
The solution is to use the recommended cert-sync tool, but it should be documented in the README

Can Someone please tell me how to draw a circle on a given layer or on a shapefile?Is there any way to draw a circle knowing the center point and the radius?Being a beginner i have very less knowledge of this part.Also if u can tell me if it is necessary to add a layer on existing layer while drawing a circle or we can draw it on the same existing layer of the shapefile using Sharpmap only?Thanks

F-Spot shows up in Gnome-System-Monitor as "Main Thread" instead of something more descriptive like "F-Spot".

While using Nunit 2.4.8 bundled with mono, the autogen.sh passes. However, the make step fails with the following error.

/usr/lib/mono/4.5/Microsoft.Common.targets:  warning : Reference 'nunit.framework, Version=2.6.3.0, Culture=neutral, PublicKeyToken=96d09a1eb7f44a77' not resolved

If the project files require version 2.6.3, the autogen.sh script and README need to be updated to reflect the updated version requirement.
