Merge lp:~widelands-dev/widelands/bug-1796364-blinking-buildings into lp:widelands

[GunChleoc]

Remove z-layering fix for building texts introduced in r8847 because it is buggy and can make building animations disappear

[bunnybot (widelandsofficial)]

Continuous integration builds have changed state:

Travis build 4280. State: passed. Details: https://travis-ci.org/widelands/widelands/builds/459059413.
Appveyor build 4074. State: success. Details: https://ci.appveyor.com/project/widelands-dev/widelands/build/_widelands_dev_widelands_bug_1796364_blinking_buildings-4074.

[Arty (artydent)]

Started reviewing the code. Have one diff comment so far. Will continue later tonight.

[Arty (artydent)]

I finished looking over it but admittedly not too deeply because it's just old code re-enabled. Code looks fine (aside from the ~ operator mentioned in the diff comment).

[GunChleoc (gunchleoc)]

I have added some asserts to the ~ operator and a comment to the enum class.

[Klaus Halfmann (klaus-halfmann)]

Hmm I don get these travis Errors,
one looks like a timeout, next one hapens only att a pecific compile?

/home/travis/build/widelands/widelands/doc/sphinx/source/autogen_ai_hints.rst:117:
Definition list ends without a blank line; unexpected unindent.

Will try to test this anyway

[Klaus Halfmann (klaus-halfmann)]

Uhm, the savegame fails me:
Assertion failed: (result >= 0), function operator~, file ../src/logic/map_objects/draw_text.h, line 38.

[Klaus Halfmann (klaus-halfmann)]

Oops was killed with:
Assertion failed: (result >= 0), function operator~, file
../src/logic/map_objects/draw_text.h, line 38.

will ty to reproduce this in a debugger.

review: Needs Fixing (testplay)

[Klaus Halfmann (klaus-halfmann)]

I attached a Debuugger and starte to play my latest youtube Video:
https://www.magentacloud.de/share/tu4ayusx.k
   Fie_: FRI01_H50_End.wgf

The asser ht me amost immediatedly when Itried to open the Map.

The TextToDraw Enum was 3 which is out of range, hence the assert.

Gun: I assume he latest merge to trunk broke something?

As I have never seen this blinking anywhere I hae no idea
what do about this now. Maybe it does not happen on OSX?

Benedikt: can you provide a videdo of this blinking?

review: Abstain (debug)

[kaputtnik (franku)]

A video is added to the bugreport in comment 1.

I have merged trunk into this branch, so appveyor should give a windows executable.

Funnily playing the saved game, with was saved with revision r8874, do work with this branch after merging trunk (so r8913).

Didn't saw those blinking buildings also.

[Klaus Halfmann (klaus-halfmann)]

Oops, Benedikt is playing in Frisian/Platdütsch that complicates the Issue :-)

I pulled the branch again and will try tommorow, hopefully merging trunk fixed
the Assertion.

A Debug builds now shows this, too:

I could reproduce the assert error and it should be fixed now.

[hessenfarmer (stephan-lutz)]

I will test a windows debug build tonight.

@ Klaus could you test this another time as well?

[hessenfarmer (stephan-lutz)]

Tested with the latest win debug build from appveyor.

no crashes and I couldn't see any blinking buildings or similar.

review: Approve (playtest)

[hessenfarmer (stephan-lutz)]

@GunChleoc

From my side this is ready to merge. Travis is not green due to a transient failure.
But as I am not an expert for this code I'll leave the decision for merging to you

[GunChleoc (gunchleoc)]

I overlooked that Arty had already done a code review. So, this is ready now, thanks

@bunnybot merge

[bunnybot (widelandsofficial)]

Refusing to merge, since Travis is not green. Use @bunnybot merge force for merging anyways.

Travis build 4536. State: errored. Details: https://travis-ci.org/widelands/widelands/builds/499415843.
