This app does not seem to work with Python 3. I think it would be a good idea to have at least basic polyglot Python 2/3 support.

I also think running using Python 3 or at least emulating python 3 would make things a bit less thorny when dealing with, for example, unicode filenames.

I'm going to create custom client for anki server. And I found your repo on googling anki web api. Looks like your anki-sync-server reproduce API of anki-web. Can you share documentation for endpoints / format of requests / params / etc. ?

Thx in advance

I installed anki sync server on vagrant ubuntu. When I start server with ./ankiserverctl.py debug and curl anki server with curl 'http://localhost:27701'`, I got a responseAnkiServer 2.0.5, which means it is working.

But when I try to reach server from host machine (windows 8), browser's response is ERR_CONNECTION_RESET. I have port forwaring set up, which works ok.

What could be a problem?

I have Debain system and installed AnkiServer using pip in virtualenv:

pip install AnkiServer
cp ./examples/example.ini production.ini
./bin/ankiserverctl.py debug

The following error appears:

import anki
ImportError: No module named anki

If I download package from PyPi and install manually (python setup.py install)
everything works fine.

I have installed the server successfully. I would rather use a personal web than the desktop version anki provides. Is there a way to link one and does anki provide a rest api for this?

If I install anki-sync-server and anki from source, and then I adjust the settings in anki so it tries to sync from my local server, sync does not work. The client and server appear to start communicating but then it errors out.

If I run the server with debug, I get the following error.

In the client, at the same time, I get the generic pop-up error.

Syncing failed:
AnkiWeb encountered an error. Please try again in a few minutes, and if the problem persists, please file a bug report.

I assume that the client is too new of a version relative to the server. But I don't know what to do about that. Is this kind of thing the kind of thing that could be fixed with some screwing around? Is it a gorilla of a problem? Thanks for any thoughts or help!

My production.ini files
At server:main, in host, put your host/ip as the same in your local network. If your IP is always changing, you have to open your Router page and assign an IP to your machine so that it always grabs the same IP when you connect your machine to the router.

Look for the line with "allowed_host" and remove it. It will work flawlessly.

use = egg:AnkiServer#server
host = 192.168.1.105

My "mysyncserver.py" file looks like this:

anki.sync.SYNC_MEDIA_BASE = 'http://192.168.1.105:27701/msync/'
anki.sync.httpCon = lambda: httplib2.Http()

In order to make it work outside network (using internet, 3g, 4g etc), you can use this tutorial:
http://www.htpcguides.com/get-nag-free-dynamic-dns-with-freedns/

There is a bug in the sync process for upload and download. This seems to related when there is a mismatch in the decks.

The Anki Desktop client is telling me to a) Upload my Deck to the Server or B) Download it, to solve the issue. Both requests are causing a expection on the client side.

There was a quite long message on the server side, while running debug. But as far as I can tell this was the content of the Anki Deck.

I'm going to try to append the output, but only a fraction of it fits into the screen.

Best regards
Akendo

It seems like unless you are just running the server locally you would need a rather specific remote host - one that doesn't timeout large media syncs, lots of storage for said media files. I'm curious how others are hosting their content remotely.

I'm looking into how much amazon would cost, but guessing I would need something additional to the ec2 instance running the server like an external s3 bucket or something like that to store the media...

When I changed the directory from the original /home/anki/anki to /mnt/hgfs/ankiServer, then the client clicked the sync button and an error occurred.

I ran the server and sync'd with Anki. I saw this in the logs:

INFO:root:CollectionThread[.../collections/anki/collection.anki2]:
Running operation_upload(*['SQLite format... (the entire contents of my deck, in sqlite3 format)

I happened to be running in an Emacs terminal at the time, which is very slow to print output, and the sync operation timed-out. I set the log level to ERROR, and everything seemed to work OK.

But, I don't ever want the entire contents of my uploaded decks to appear in log output. Can this log line be modified to not include the entire contents, or at least bump to DEBUG level?

See https://github.com/dsnopek/anki-sync-server/blob/2.0.6/AnkiServer/threading.py#L91

There seems to be an easier method of pointing Anki to the server, in the source I found:

SYNC_URL = os.environ.get("SYNC_URL") or "https://ankiweb.net/sync/"

So you could set the sync url by just setting the environment variable $SYNC_URL (untested).

This error happens when some users try to sync media sometimes. I don't know if it's tied to specific data in their collections, but it does usually happen several times in a row - and then doesn't happen again for a while.

I suspect this might have to do with an os.chdir() in the media sync'ing code which is a totally dangerous thing to do in a multithreading application - but I haven't had a chance to test that theory.

Overall, I don't think we need the 'send2trash' functionality on the server, so that can probably be removed all together.

The README mentions the debug command, but the most recent version in pip does not have that, because it's almost a year old. Of course one can clone from github as need be. Is that the desirable installation method? I'm OK with whichever, and it'd be nice for the documentation to match.

First, Thanks for building this wonderful project!
I've tried this project's instruction on Win10 64bit with python 2.7 and get some error.
Kindly help to check the solution, thanks.

Hi.
When i run this server with the bundled Anki (i.e. v2.0.11/dae/anki@1a9ef37) and use a new (2.0.18 or 2.0.19) desktop client, the sync process always wants to do a full sync. With the desktop Anki downgraded to the same commit it seems to work fine.

Hi, first, thank you for your work.

I manage to get anki-sync-server to run on my personnal server, I use it with 2 devices (1 one computer, and one phone). But each time that I do make a change on a device or on the other I get this error telling me that my decks can't be merged !

This is a pain, can you do something ?
Thanks again

I'm trying to setup anki-sync-server in combination with nginx because I want to use TLS (configured on port 27702). The anki-sync-server itself is working, I can sync when I connect directly to port 27701 over HTTP.
I used the recommended code snippet for nginx from the README page. But I had to change line
proxy_pass http://anki:27701;
to
proxy_pass http://127.0.0.1:27701;
because the orignal line was giving the error message:

nginx: [emerg] host not found in upstream "anki" in /etc/nginx/conf.d/secure.conf:92

When I press the sync button in Anki I get the error message:

Syncing failed:
AnkiWeb is under maintenance. Please try again in a few minutes.

In the logfile of nginx it says:

2017/05/03 00:24:18 [error] 2128#2128: *1783 connect() failed (111: Connection refused) while connecting to upstream, client: 1.1.1.1, server: mydomain.net, request: "POST /sync/hostKey HTTP/1.1", upstream: "http://127.0.0.1:27701/sync/hostKey", host: "mydomain.net:27702"

(I replaced my IP adress with 1.1.1.1 and the domain name of my server with mydomain.net in the error message for privacy reasons)

@Akendo I saw the issue #45 you raised for media sync. also noticed @cdpm provided a fix #46 for it.
I got same problem as you mentioned in comment, deleted files from anki PC, then trying to sync by using ankidroid, the console says file missing.

seems it is still trying to download those media files which was already deleted.

any ideas? thanks.

Hi !

I recently started to use Anki and now I want to synchronize my decks with a hosted server. I manage my services using Docker, so I wrote a quick Dockerfile for your server and you can find the result here. I'm using the latest version of AnkiServer on pip: 2.0.6.

Everything seems to work well, I can enter my username and password (I'm connecting with AnkiDroid), but when I try to synchronize, AnkiDroid fails due to "Internal Server Error (500)".

Meanwhile, on the server side, I get the following logs:

Any idea on why this happens ?

Hi,
i'm try make web client 4 anki , but have some problem in scheduler.

i have test collection and deck with reseted scheduler. On start learning, i have this value on scheduler counters
[learning_cards] => 0
[review_cards] => 0
[new_cards] => 20

while i make response, value in new_cards decrease not every time when i make positive response, and after several time (perhaps 15 minuts or less) counters make reset to 0,0,20 again.
Not understand why in can happen?

I am using Anki desktop Version 2.0.44 on Windows
I am using AnkiDroid (2.9 version mentionned in help)
Sync server is running on ubuntu on raspberry (anki 2.0.32 installed on server + anki-sync-server install procedure , ubuntu version Linux raspberry 4.4.38-v7)

When I do modification on AnkiDroid only, then doing sync, it is ok (files are pushed on server).
When I do modification on Anki Desktop only, then doing sync, it is ok (files are pushed on server).
The problem is when I do modification on Anki Desktop, then sync on Anki Desktop, then try to sync on AnkiDroid. I then get an error message, and I have to overwrite.
And conversly if I do modification on AnkiDroid, then sync on ankidroid, then try to sync on Anki desktop, I have to overwrite.

I am able to synchronize cards between my two devices, but I get error messages, and have to overwrite.
Do you have any idea of why it happens?
Is there any way to troubleshoot that?

Timezone seems ok on server.

Thanks

I have a box running Debian sid. I make a new directory, install everything as documented, and I can't run the server. Help?

$ mkdir anki
$ virtualenv anki
$ cd anki

OK, maybe I should add a user first. That appears to work.

./ankiserverctl.py adduser joe2
Enter password for joe2: 
Password: 

The data and password files and directories look OK, as far as I can see, but if I try running the server, the above error shows up just like before.

Help?

Hi David,

I would like to run anki-sync-server over SSL, but pointing SYNC_URL to the HTTPS URL is not enough because Anki does SSL certificate validation and only accepts the certificates for AnkiWeb in ankiweb.certs. Are you aware of any workaround?

-ag

I noticed with the latest Anki 2.0.39 version, the PREFIX in makefile has changed from:

PREFIX=/usr

to

PREFIX=/usr/local

This causes sudo make install to install Anki in a different directory than for previous versions, which causes a ImportError: No module named anki when you try to start the server. I wish I could point you to where in the repo this change happened but it looks like Damien bumps the version from 2.0.36 to 2.1 alpha without any mention of going to 2.0.39. However, you can take a look for yourself in the 2.0.39 tar.bz2 or on the ankisrs.net changes page.

Here's how to reproduce the error in Ubuntu 16.04.

Install Anki 2.0.39

wget https://apps.ankiweb.net/downloads/current/anki-2.0.39-amd64.tar.bz2
tar jxvf anki-2.0.39-amd64.tar.bz2
cd anki-2.0.39
sudo make install

Install AnkiServer

sudo pip install AnkiServer
cd /usr/local/bin

Configure AnkiServer

sudo touch production.ini
sudo gedit production.ini

Start AnkiServer

sudo ./ankiserverctl.py adduser test
sudo ./ankiserverctl.py debug

Which produces the following error:

Traceback (most recent call last):

Workarounds:

Fortunately installing via the 2.0.39 deb file works without any problems. Also, going back to 2.0.36 works as well.

I tried simply changing the PREFIX=/usr/local in the makefile back to PREFIX=/usr and doing a sudo make install from there, but that still does not solve the problem.

• OS: Archlinux
• About Anki: Version 2.1.0a10
• Qt 5.8.0 PyQt 5.7.1

After update descktop app fulfilled daily tasks. Pressed 'Sinchronize with AnkiWeb' and got following error.

An error occurred. It may have been caused by a harmless bug, 
or your deck may have a problem. 
To confirm it's not a problem with your deck, please run Tools > Check Database.

Hello,

Thanks for working on this!

I've been trying to use anki-sync-server to see if I could sync to a collection on a personal server from my phone:

https://github.com/dsnopek/anki-sync-server

After much wrangling, I have been able to get the server running, so I can sync my Anki Desktop application to it. However, I've been having trouble getting my phone to sync with it using the following entries in the AnkiDroid Custom Sync server:

Sync url https://192.168.1.149:27701/

Media sync url https://192.168.1.149:27701/msync/

This IP address match what I have on my production.ini file and the mysyncserver.py plugin file. But when I try to sync with AnkiDroid on my home wifi, I am immediately getting a connection timeout error message, so I believe I may have missed something in configuring the server. However, the message takes less than a second to appear, so I don't think it's a matter of the connection taking too long, it seems to be denied altogether.

Can you please help me with this?

Thanks!

Hello,

I'm having some trouble while trying to install Anki Server from source. I'll walk you through what I did:

Install all the dependencies we need using easy_install or pip:

$ easy_install webob PasteDeploy PasteScript sqlalchemy simplejson

Or using pip:

$ pip install webob PasteDeploy PasteScript sqlalchemy simplejson

Or you can use your the package manager provided by your OS.

This went okay. I did sudo pip install webob PasteDeploy PasteScript sqlalchemy simplejson instead, if that matters.

Download and install libanki. You can find the latest release of Anki here:

http://code.google.com/p/anki/downloads/list

Look for a *.tgz file with a Summary of "Anki Source". At the time of this writing that is anki-2.0.11.tgz.

Download this file and extract.

Then either:

Run the 'make install', or
Copy the entire directory to /usr/share/anki

This went okay, too. Except I installed version 2.0.39 using sudo make install.

Make the egg info files (so paster can see our app):

$ python setup.py egg_info

This is where I'm having trouble. This is what I did after cloning the anki-sync-server github repo:

test@test-VirtualBox:~/anki-sync-server$ sudo python setup.py egg_info
running egg_info
creating AnkiServer.egg-info
writing requirements to AnkiServer.egg-info/requires.txt
writing AnkiServer.egg-info/PKG-INFO

warning: no previously-included files matching '*.pyc' found under directory 'anki-bundled'
no previously-included directories found matching 'anki-bundle/.git'
writing manifest file 'AnkiServer.egg-info/SOURCES.txt'

As you can see, I have a few warning messages. The libraries didn't end up in the usual place (/usr/local/lib/python2.7/dist-packages) and I have been unable to launch the server. What am I doing wrong?

Thank you!

We've recently gotten a number of reports of people trying Anki Server but it not starting and them getting no feedback:

https://groups.google.com/forum/#!topic/anki-sync-server/OaOadyGmzAE

https://groups.google.com/forum/#!topic/anki-sync-server/IXGpxsdWfOs

It looks like ankiserverctl.py is routing all output to /dev/null. It should either (1) send something out to the console (maybe stderr?) or (2) log stdout/stderr somewhere. When running with supervisord, both stdout/stderr get logged by it which I find very useful, personally...

Hi, first, thank you for your work.
I try to get anki-sync-server to run on my linuxmint 17.1.
I do it following these steps
sudo apt-get install python-pip
sudo pip install AnkiServer
cd /usr/local/bin
cp /usr/local/lib/python2.7/dist-packages/AnkiServer-2.0.6-py2.7.egg/examples/example.ini production.ini
./ankiserverctl.py adduser
./ankiserverctl.py debug
./ankiserverctl.py start
it works great.

and then I open port for anki-sync-server

sudo vim /etc/iptables.firewall.rules
*filter

hi team:
I installed this package (2.0.6) by using easy_install, I successfully logon as username "test" in anki windows client, and anki client prompt me to upload/download all deck info for first time sync, I choose upload. then I got some errors in console.

seems something happened after checking log file

in operation_upload
os.rename(temp_db_path, session.get_collection_path())
WindowsError: [Error 183]

WindowsError: [Error 183] in python usually means you just can not rename that file because it already exists.

According to the following pull request on the Anki-Android repo, the ability to use a custom sync server is now enable for the Android client. Haven't tested it though.

(After confirmed as usable) please update your README accordingly.

If you get the error called "no module named Anki" on Windows, simply copy the anki-bundled folder to

C:\Python27\lib\site-packages (put inside this folder)

Your structure must be like this:
C:\Python27\lib\site-packages\anki-bundled

It works flawlessly.

Hi,

in api I don't see how I can get tags from a deck instead of all decks of collections.
Did you plan to implement an "list_tags_by_deck" or something like that ?

Regards,

In debug with media sync sometimes I get this:

192.168.0.24 - - [20/Aug/2017:16:01:39 -0500] "POST /sync/meta HTTP/1.1" 200 115 "-" "Python-httplib2/0.7.7 (gzip)"

    return fmt.format(record)
  File "/usr/lib/python2.7/logging/__init__.py", line 467, in format
    s = self._fmt % record.__dict__
MemoryError

I'm on ubuntu bash on windows. I managed to get the server running, but my deck has about 200k media cards. I originally got a memory error, but now the server in debug mode doesn't say anything and the anki client says the string buffer error below, under the condition i don't do a media sync.
I'm getting this ambiguous error and not able to figure out what the bad response actually is, since anki only throws this up:

Syncing failed:
Traceback (most recent call last):

  File "json\decoder.py", line 366, in decode
TypeError: expected string or buffer

The reason for me doing a custom server is because I hope to get around the 250MB collection limit. Is it possible to only sync with the custom server your base and no media - since there is no restriction on collection media size?

I removed the line from mysyncserver.py to be, but get the same ambiguous error

import anki.sync
anki.sync.SYNC_BASE = 'http://127.0.0.1:27701/'

and removed anki.sync.SYNC_MEDIA_BASE = 'http://127.0.0.1:27701/msync/'

If I disable media sync, things work just fine.

I'm not good at English.So I can only briefly describe the situation.
I encountered some errors during the execution of the program like the picture.

I've recently forked this project to dockerize it, which went pretty smoothly. I'd like to send a pull request to merge this in, but before then I think it would be great if there were a RESTful way to add & delete users, and change their passwords.

If this project is still under active development, it would be great if this could be added. Glancing at the code it looks like it would be pretty easy to add, but I'm new to Python. The interface could itself be protected by a username & password that the server gets from the environment, which is easy for Docker users to set at deploy time.

Also, to facilitate docker deployments, it would be most welcome if the various databases could be created in a subdirectory containing nothing else, so that this directory can be mapped to persistent storage on the host.

I'm willing to do all this work myself, but I thought I'd open an issue first to give you the opportunity to do it yourself and avoid any potential blunders by a Python newb like myself.

I switched from AnkiWeb to this sync server a few days ago, and I've encountered this problem multiple times since then. Tried Check Database, and full sync multiple times, but it didn't solve my problem.

I couldn't exactly pinpoint what causes this problem, but is seems like doing a bunch of reviews or editing a few cards can trigger this error. After doing some reviews on AnkiDroid and then sync, when I try to sync with desktop anki, I sometimes get "Your collection is in an inconsistent state." error, and forces a full sync. The same can happen if I edit my cards on desktop, and try to sync back to AnkiDroid.

I tried what happens if I leave out AnkiDroid and try to sync between two desktop an ankis. I've rescheduled some cards on computer A, synced A, synced B, looks ok, except the changes are not visible on B. If I force a full sync, changes appear on computer B too.

I use the version from pip in a virtualenv (I had to work-around #40 by moving the anki-bundled folder into lib/python2.7/site-packages...). ankiserverctl.py debug doesn't show any obvious errors or problems.

There is a particular user who gets this error any time they sync:

I don't know what in particular is up with their collection that this happens - I'll attempt to determine that. However, this error occurs when the Anki Server is attempting to close the collection - which means it never gets closed and the server keeps trying over and over again. In fact, the only way to stop it, is to restart the server!

So, even if I don't figure out what's causing this, I need to at least change the close code to make sure it gets closed (even if it's forced!) so that we don't have an infinite loop.

Hello,

I've been experiencing some odd behavior regarding the sync on AnkiDroid. Sometimes when I sync, "Writing changes into database..." will hang at 1459 kB for about 3 minutes, after which I get the error message:

The cards seem to update, but the media doesn't. I tried syncing against an empty folder, but only about 1/3rd of the media downloaded, then I got the error message above. This issue is only happening on my phone. Desktop-to-desktop syncs work fine.

I did a hard reboot of my phone and I was able to redownload all the media files. I then added some media to my desktop collection to see if I could sync it to my Android phone. The syncing screen took a minute, but I was able to successfully sync the media. I'll see if I can reproduce the issue.

Here is the stacktrace seen in the wild:

Unable to answer_card(*[<AnkiServer.apps.rest_app.RestHandlerRequest object at 0x179da50>], **{}): 'Scheduler' object has no attribute 'lrnCount'
Traceback (most recent call last):
  File "/opt/anki_server/src/anki-sync-server/AnkiServer/threading.py", line 95, in _run
    ret = self.wrapper.execute(func, args, kw, return_queue)
  File "/opt/anki_server/src/anki-sync-server/AnkiServer/collection.py", line 58, in execute
    ret = func(*args, **kw)

  File "/usr/share/anki/anki/sched.py", line 549, in _answerLrnCard
    self.lrnCount += card.left // 1000
AttributeError: 'Scheduler' object has no attribute 'lrnCount'

It happens when a review is started (reset_scheduler(), next_card()), the Collection is closed for inactivity, and THEN the user does answer_card(). The Collection is re-opened, but reset_scheduler() isn't run.

The error will only appear when the card is in the "learning" queue, but it's probably a problem in many other cases. For example, .next_card() won't necessarily know the current deck and so who knows what it will return!

Additionally, in the specific case of answer_card(), we're marking as @noReturnValue, so the error never bubbles up to user. They don't even know that their answer wasn't recorded. :-/

Beyond this specific issue, this is a problem of using a stateless protocol (HTTP) to work with an inherently stateful system (Anki). I'm not sure what the full solution is... Maybe passing some sort of session setup information with every call to .next_card() and .answer_card()? That way, if the schedule isn't setup, it can be re-setup?

I'm not yet sure how to handle this...

I can run ./ankiserverctl.py debug without errors, but when I try to use it as a customer sync server for my desktop anki, I can't log on. Does it need additional set up to make it work? I'm from china, and the official ankiweb is very slow, so it would be so nice to have a personal anki sync service running on my server. Thanks for you hard work!

Please note the anki-bundled directory is a git submodule.

Simply run git submodule update will sync it.

And this step is useless if you have submodule initialized.

2. Download and install libanki. You can find the latest release of Anki here

There is a problem after pip install AnkiServer:

1. Server code need run with python2.
2. Anki code in anki-bundled fold need run with python3.
   How to resolve this?

From the README:

Download and install libanki. You can find the latest release of Anki here:

http://code.google.com/p/anki/downloads/list

Look for a *.tgz file with a Summary of "Anki Source". At the time of this writing that is anki-2.0.11.tgz.

There are no longer any download links at http://code.google.com/p/anki/downloads/list, and based on Google Code's end-of-life status, I doubt they will ever be restored.

I was able to find the Anki source via the following method:

Go to https://apps.ankiweb.net/

In the section "Download Anki" select "Linux/BSD".

In the "Other Options" section, there should be a link reading "Source .tgz". At the time of writing this file is called "anki-2.0.45.tgz".

The README should be updated to provide a working path to download the Anki source.

Hi

I did run in on of my decks following check_media feature to clean up all of my unnecessary elements.

Afterwards I did sync to the anki-sync-server.
But the sync nerver finsihed, the client is keeping uploading to the server without any progress.

In the logs files I can see that he's executing all the time the uploadChanges .

at first I can see how some payload is uploaded, but then I can't see any change.
It seems to me like a loop that is not finished or something.

Any idea?

When installing in a fresh virtualenv, trying to run ankiserverctl.py gives:

ImportError: No module named httplib2

I believe this is just a matter of adding httplib2 into the dependencies in setup.py. Installing httplib2 with pip fixes the issue.

I found out about the project and as far as I can tell the server itself doesn't require anything graphical or X-related. However, at least for my Linux distro, anki itself is a dependency, which necessitates all of X. Of course, I was keen to use this on my headless server (for my home LAN), and would very much prefer to not install that whole set of packages.

Is there something I've fundamentally misunderstood / overlooked about how anki-sync-server operates? If not, should I request the maintainers of anki-sync-server that "anki" no longer be a dependency, or at least be "optional"?
