alex2108 / syncthing-tray Goto Github PK

After few days I noticed my memory is getting low and syncthing-tray was on the top 11GB usage :D

Win10, 64x

I was using parameter -target="http://user:pass@localhost:8080" which apparently stop working on version 0.13. I removed user:pass and added -api="key" paremeter

I know Mac support wasn't ever officially mentioned but prior to syncthing v0.13.2 I was using syncthing-tray v.3 without any issue, but since upgrading to syncthing v.0.13.2 and syncthing-tray v.4 I've been having issues. Everything is working great on my debian box and would love to use the new version on my Mac. Unfortunately my Go knowledge is very minimal so I'm not sure where the issue is or if it's an easy fix, but I appreciate your time and I'm willing to test anything. Thanks.

It shoud be possible to get rid of gcc dependency for system tray icon on Windows - lxn/walk#68

Hi there,

I want to let you know I'm personaly using/packed Syncthing and syncthing tray for Mac OS X inside a DMG/App bundle. The syncthing-tray works perfect on Mac OS X.

https://forum.syncthing.net/t/mac-os-x-native-app-and-disk-image-installer-proof-of-concept
https://github.com/jerryjacobs/foo-app/releases
https://github.com/jerryjacobs/foo-app/tree/syncthing-tray-app

Thanks for you work, hopefully I will create a "real" package for the Syncthing community which they can use to distribute Syncthing on Mac OS X.

Kind regards,
Jerry

syncthing commit: syncthing/syncthing@bf7fcc6

workaround for now: provide apikey via -api INSERTSTAPIKEY

I don't see a pattern here, it just works for some time and then stops updating, tray menu also doesn't work. Log doesn't contain anything useful just state changes. Works fine on my Debian jessie amd64 though.

Hello,

Can you please release a 32-bit binary as well as the 64-bit? I noticed there is a 32 for Windows but not Linux. I typically would use 64-bit Linux but for an older machine I use 32. I'd greatly appreciate it.

It would be nice to have more info in icon tooltip text like

• current Download/Upload Rate
• Last File Received per device
• syncing errors

I found around 660,000 icon files (taking 2.4GB of space) in my temp directory (on windows 10 x64).
systray_temp_icon692992209 and similar.

It seems like it checks if the certificate domain matches the domain given via -target, which fails because of syncthings self-signed certificate with a fake domain:

ERROR: Get https://localhost:8080/rest/config: x509: certificate is valid for syncthing, not localhost

I run syncthing-tray with
./syncthing-tray -target="http://localhost:8384"

As expected, in my tint2 panel a red icon appears, and almost immediately it turns blue. However, there are no further changes in the icon's state, although in the console I get a lot of messages like this:
2015/09/29 12:28:06 main.go:345: updating status

2015/09/29 12:28:07 main.go:390: ul+dl

(and the icon /tmp/trayhosticon100407285 is correct).

Output of command /usr/bin/syncthing-tray as super-user - even if it doesn't make any sense, Icon stays red

I've tried using -u and -p

I've tried as:

-u username -u=username -u="username"

same with password

I suggest MIT, @rkfg are you fine with that? Since you contributed a change to the icon I wanted to ask.

Please see screenshot below:

Similar to: https://github.com/iss0/SyncthingTray

I think it should show when connected to a device, disconnected from a device, syncing

It would be nice to get host:port setting from syncthing config.xml if it is not set explicitly.

As the title suggests, there are several TLS handshake errors before it closes.

Hi,

I wanted to point to a stable version in my syncthing-mac build script but the gopkg.in sourcefile proxy will not allow the v0.5 but only allows major versions:

http://gopkg.in/alex2108/syncthing-tray.v0.5

This works:

http://gopkg.in/alex2108/syncthing-tray.v0

I can't determine which version of syncthing-tray I am running. It doesn't contain any identification info.

It would be awesome if this application would allow to authenticate with the syncthing/pulse ui via for example -user="username" -password="password".
Thanks for the great work on the indicator so far!

Once or twice each week, Syncthingtray crashes. Interestingly, when it crashes on one computer, it crashes on the other computer on which it's installed on my LAN. Here are the details:

Faulting application name: SyncthingTray.exe, version: 0.3.1.0, time stamp: 0x53e3b2a5
Faulting module name: KERNELBASE.dll, version: 6.3.9600.17415, time stamp: 0x54505737

First computer: Windows 8.1 64 bit.
Second computer: Windows 10 Insider Preview build th2_release 10525 (but prior to that, Windows XP SP3, on which Syncthingtray also crashed regularly)

Just before the application error above, I get a .NET runtime rror:

not sure if this helps since I was not running the most recent version here :/
should probably include some version info in my builds...
