cloudstorage: try to pick between multiple cloud servers

2021-04-19T19:51:01Z

The backend infrastructure will soon be able to support more than one cloud server which automagically stay in sync with each other. One critical requirement for that to work is that once a session was started with one of the servers, the complete session happens with that server - we must not switch from server to server while doing a git transaction. To make sure that's the case, we aren't trying to use DNS tricks to make this load balancing scheme work, but instead try to determine at program start which server is the best one to use. Right now this is super simplistic. Two servers, one in the US, one in Europe. By default we use the European server (most of our users appear to be in Europe), but if we can figure out that the client is actually in the Americas, use the US server. We might improve that heuristic over time, but as a first attempt it seems not entirely bogus. The way this is implemented is a simple combination of two free webservices that together appear to give us a very reliable estimate which continent the user is located on. api.ipify.org gives us our external IP address ip-api.com gives us the continent that IP address is on If any of this fails or takes too long to respond, we simply ignore it since either server will work. One oddity is that if we decide to change servers we only change the settings that are stored on disk, not the runtime preferences. This goes back to the comment above that we have to avoid changing servers in mid sync. Signed-off-by: Dirk Hohndel

cloudstorage: add API to just update on-disk setting

2021-04-19T19:51:01Z

This way we can change the host that we will use next time the app runs. Signed-off-by: Dirk Hohndel

cloudstorage: some cleanup of cloud url handling

2021-04-19T19:51:01Z

We know the preference is never empty, so stop testing for this. But don't maintain two different preferences with basically the same content. Instead add the '/git' suffix where needed and keep this all in one place. Simplify the extraction of the branch name from the cloud URL. Also a typo fix and a new comment.

mobile: add GF fields for ceiling calculation

2021-01-19T20:34:46Z

Adds fields to the advanced preferences page to modify GFLow and GFHigh for the Buhlmann decompression model for calculating ceilings. Updated preferences code to set the Buhlmann parameters in core/deco.c when the GF prefs are updated. Signed-off-by: Doug Junkins

preferences: remove pointless member

2021-01-06T18:18:23Z

This could never have worked the way it was used. Some whitespace fixes snuck into this commit. Signed-off-by: Dirk Hohndel

prefs: add option to display only actually used tanks

2020-12-13T19:49:59Z

A user complained about the default cylinders list. Provide a preferences option to turn this off. When changing the preferences, the tank-info model will be completely rebuilt. Currently, this is a bit crude as this will be done for any preferences change. Suggested-by: Adolph Weidanz Signed-off-by: Berthold Stoeger

revert preference settings for title color

2020-11-04T22:51:55Z

Because of subsequent changes there is no clean way to just revert the changes introduced in commit 8b36cf1051 ("desktop: offer different colors for info tab titles"), so this manually removes the parts we don't need anymore. This also restores a tooltip value that was inadvertantly removed in that commit. Signed-off-by: Dirk Hohndel

desktop: offer different colors for info tab titles

2020-11-04T07:08:39Z

Add a preference option to set the color of the text on the information tab to either MediumBlue, LightBlue or Black. The last two of these colors are meant to enable areadable font contrast on displays with dark mode. The choice is saved with the other preferences. [Dirk Hohndel: this isn't really about dark mode, so changed many of the types and variable names, changed the user visible texts, and addressed some whitespace issues] Signed-off-by: willemferguson Signed-off-by: Dirk Hohndel

desktop: remove user survey

2020-04-19T21:27:54Z

We have never made good use of the results. Let's just remove it. Signed-off-by: Dirk Hohndel

cleanup: don't call uiLanguage() in qPref::loadSync()

2020-03-22T19:01:09Z

uiLanguage() initializes the language fields from the preferences values. It is unclear why this function is called in qPref::loadSync() *before* the fields are loaded from disk. It can only initialize to the default values anyway. After qPref::loadSync() uiLanguage() is called again so that everything can be initialized with the correct perferences values. Remove the first call. If things break, let's fix them in a sensible way. Signed-off-by: Berthold Stoeger
