Nextcloud 11.0.0, OCR 2.0.0.

When trying to OCR and OCRWorker ist not running, the OCR queue is getting big and bigger.

After starting OCRWorker, freshly queued documents will be OCR'd, but the old the OCR queue from before won't vanish.

Also Apache log will be filled up a lot.
"GET /apps/ocr/status HTTP/1.1" 200 997 "

Can only disable the app at the moment until the bug is fixed.

Bug report

Expected Behavior

I have tried to install this app by downloading tarball from Nextcloud appstore and by cloning the repo. It should appear as an inactive app.

Current Behavior

App can't be found in list.

Steps to Reproduce (for bugs)

1. Install tesseract and ocrmypdf from package manager (Raspbian 8 unstable)
2. Clone git repository / donwload from NC appstore.
3. Open app settings page
4. App isn't there.

Context

I have tried to install the app from the old Owncloud apstore. As it is not there, I changed my settings.php to point to NC appstore. I couldn't find it there so I tried to download the tar.gz from there. I noticed there were some problems with file permissions and I fixed them manually, but app doesn't appear in the list.
I have also tried to install app by cloning the repository. I find the same permission issue.
The permissions in app folder are:

• -rw-r--r-- in files
• drwx------ in folders
  I checked other apps permisssions and I see the folders permssions are drwxr-xr-x.
  Additionaly, when there is an ocr folder in nc/apps, the 'disabled' section can't load, there's only the spinning circle. Erasing the ocr folder fixes this.

Bug report / Feature request

Expected Behavior

A file in a folder shared by another user should be able to be processed by the OCR app.

Current Behavior

Currently you may select files shared by other users and start the OCR process but it never finishes since the file is not accessible via nextcloud/data/user/current_user/files.

Possible Solution

There are two possilbe solutions: 1st: disallow OCR processing of shared files or 2nd implement a possibility to find out the real path of the file to process - and if writable by the current user, process it.

Steps to Reproduce (for bugs)

1. Share a directory of user A to user B, writeable.
2. Put a PDF in it.
3. Log in as user B, select the file and
4. choose OCR from the context menu.

Log File Content (nextcloud/owncloud.log of the "data"-directory)

OCRWorker outputs "ERROR - File not found"

Create the remaining unit tests for better test coverage. maybe exclude the worker from coverage report.

Fix the failing build. It only is an issue for php7 build.

Provide a better documentation, also for php7 and gearman for example.

Feature request

Expected Behavior

If a command/file fails to process the OCRWorker will recieve error messages which can be very helpful for bugtrakcing AND problem resolution for the user.

Current Behavior

Nothing of these messages is logged nor displayed during the status update to FAILED.

Possible Solution

The whole message which is recieved by the OCRWorker could be transferred (via tmp file solution) to occ command and get logged and shown as a "mouse-hover-tip" in the personal settings page.

Context

It would result in an easier bug tracking and provide much more information for the reason of a failed file.

I will test the app with ubuntu 14.04 LTS on a VM in the next days.

OCRWorker.php is running as a systemd service, as described in the documentation, with the correct user and group www-data same as the web server.
Yet, OCRWorker fails to ocr a newly uploaded pdf file.

Bug report / Feature request

Expected Behavior

The documentation states that, OCRWorker.php is supposed to automatically ocr a newly added pdf file.

Current Behavior

It doesn't ocr the pdf file, even after waiting about an hour. However, the command in the overlay menu, does indeed ocr the file.
Would prefer the automatic ocr to be working.

Possible Solution

Where to look to troubleshoot this?
Is there a log?
Has anyone had the same issue with OCRWorker and solved it?

Steps to Reproduce (for bugs)

1. Install the ocr app, and its prerequisites, as describe in the documentation.
2. Install the OCRWorker.php daemon using the systemd option as detailed in the wiki.
3. Upload a pdf file containing a scanned document, to owncloud/nextcloud.
4. Watch the process list, OCRWorker.php is doing nothing, even after a long time.
5. Click on the overlay menu, start the the ocr manually, watch the process list, the daemon OCRWorker and tesseract run with high load for 10 seconds, and a new file is produced adjacent to the original file, with _OCR.pdf suffix, correctly containing the ocr'ed data.

Bug report

Expected Behavior

Enabling the OCR app in Nextcloud 11 should succeed

Current Behavior

App "Array" cannot be installed because the following dependencies are not fulfilled: The command line tool ocrmypdf could not be found

Possible Solution

Steps to Reproduce (for bugs)

1. Install Ocrmypdf-tess4 docker image
2. Alias the ocrmypdf command using
   alias ocrmypdf='docker run --rm -v "$(pwd):/home/docker" ocrmypdf'
3. Run ocrmypdf on the CLI. (Success.)
4. Attempt to enable app in Nextcloud.

at the moment the js code is really ugly and not testable at all. I want to setup a package.json inside the "js" folder:

• js:

  • src
  • dist
  • test

• Webpack as bundler for the dist/ocr-app.js file (npm run buildApp).

• Webpack as bundler for the dist/ocr-personal.js file (npm run buildPersonal).

• Jasmine for unit tests (separate tsconfig.json) (step: npm run test).

• Restructure the client code to a good class structure.

• Add unit tests for the classes/methods.

• Adjust the php application to only include the ocr-app.js file in the dist folder.

• Adjust the .travis.yml that the node_modules are installed and tests run properly.

Bug report

Following the Supervisord example results in the file sitting in the queue.

Expected Behavior

To process the files

Current Behavior

The file stays in a pending mode

Possible Solution

I added user=www-data to supervisord.conf which fixed it.

Steps to Reproduce (for bugs)

Install per current instructions

An installation of the OCR app on Debian Stretch fails to work. Users are able to start the OCR with a selected language, but then see a never ending sequence of messages reporting that "Temp file does not exist.". This sequence can only be stopped by hacking the database and removing the row related to the OCR job. Technically, the code should reset the job status before raising the exception (see pull request #64).

The file which was not found exists in /tmp/ and has the correct permissions. Nevertheless, the PHP code claims that the file does not exist. This is caused by a security feature of systemd: apache2.service gets its own /tmp directory. Therefore /tmp seen by PHP code running in Apache2 is not the same as /tmp seen by the OCRWorker.php process.

It is possible to disable the security feature with a private /tmp for apache2.service, but that would be a bad solution. The better solution is using systemd to start OCRWorker.php and tell it to share /tmp with apache2.service. This works for me.

I downloaded the master.zip and the 0.8.8: same error.

I put the folder in apps/ and open the App webpage. Can't display the list of disabled appsand I got this message:

Array to string conversion at /home/www/kh.ro/dev/nextcloud-dev/settings/Controller/AppSettingsController.php#238

Feature request
This may already be available and implicit in docs and I've just failed to understand it.
Make it possible to have the OCR work running on another server to help split workloads

On larger installations (250+ users, 1m+ docs) the servers have been specified for the job envisaged. Adding in (the very useful) OCR functionality puts additional load on the frontend server and potentially impacts UX for all users; offloading it reduces impact and also means the OCR server is more easily updated/optimised.

I will test the app on nextcloud with raspbian.

Bug report

Expected Behavior

The file should be OCRed as in any other common Nextcloud folder.

Current Behavior

An error is outputted in the top area of the web interface and the file is not processed.

Possible Solution

Steps to Reproduce (for bugs)

1. Install the "External storage support" app
2. Create a local folder in the server, mine (/data/data) is out of the /var/www/nextcloud path, this folder should be owned by www-data user and group, for more details please check https://docs.nextcloud.com/server/11/admin_manual/configuration_files/external_storage/local.html
3. In the Admin > External storages add the previously configured folder
4. I have added a file through the Nextcloud Mac OS X client
5. I tried to OCR the file via web interface and it showed an error.

Context

I'm trying to OCR a file in a external storage local folder to made it available to other users with access to this folder.

Mark a folder and process it. Maybe even specify a folder in the user settings, which then can be processed automatically by the cron jobs in nextcloud.

Most parts of ocr service are left out, because of global php functions.

It would be useful to have the ability for the app to use instances of the required dependencies:
a) OCRmyPDF
b) tesseract-ocr
Present at an external site, if this is possible.
This would benefit those using hosted Nextcloud versions where they cannot control the software on the server.

Currently JPEG2000 images are not supported.

Those files are typically named *.jp2 and use the mime type image/jp2 which is supported by Tesseract 3.x and could be added to the OCR app.

Some more image formats are also supported by Tesseract 3.x and missing in the OCR app.

Bug report

Expected Behavior

I'm trying to install the OCR app on a Nextcloud 11.0.0 installation with PHP 7.0.
Tesseract and Ocrmypdf commands are installed and executable for any user:

% which ocrmypdf
/usr/local/bin/ocrmypdf
% ls -l /usr/local/bin/ocrmypdf
-rwxr-xr-x  1 root  wheel  242 Dec 20 19:53 /usr/local/bin/ocrmypdf

% which tesseract
/usr/local/bin/tesseract
% ls -l /usr/local/bin/tesseract
-rwxr-xr-x  1 root  wheel  21280 Dec 15 01:42 /usr/local/bin/tesseract

Current Behavior

When I click "Activate" in the Nextcloud App Admin, I get the following error message:

App "Array" cannot be installed because the following dependencies are not fulfilled: The command line tool ocrmypdf could not be found The command line tool tesseract could not be found

In the Admin/Logging section I can then see two error messages:

Error PHP Array to string conversion at /next/data/nextcloud/lib/private/legacy/l10n/string.php#72

Error core App "Array" cannot be installed because the following dependencies are not fulfilled: The command line tool ocrmypdf could not be found The command line tool tesseract could not be found

OCR should be written in uppercase letters.

Evaluate and compare the php native semaphore features. Maybe we can get rid of gearman.

Feature request

Expected Behavior

More tests which cover the whole ocr service part. not only a little of them.

Current Behavior

Most parts of ocr service are left out, because of global php functions which cannot be mocked.

Possible Solution

Maybe we can build up a better environment where the global functions can be processed correctly in travis. (As for now the processing is available in local dev env only)

Context

The project becomes more reliable with this.

See nextcloud/server#2139

To properly work with Nextcloud 11+ the appinfo.xml needs following entry in the <dependencies> tag (of course adjust the numbers to the ones that actually work ;)):

<nextcloud min-version="9" max-version="11" />

cc @janis91

https://github.com/janis91/ocr/blob/master/templates/settings-personal.php#L16

The info.xml should be also translated according to get a better understanding for other users, what this app is about.

should be included for translation.

Bug report

NC Version 11.01, current OCR app.

When I want to OCR a file that has been uploaded by me, but resides on a directory that has been shared to me, OCR will not start but display an error in the log:

OCP\AppFramework\Db\DoesNotExistException: Did expect one result but found none when executing: query "SELECT file_target FROM *PREFIX*share WHERE file_source = ? AND share_with = ? AND uid_owner = ?"; parameters Array ( [0] => 168228 [1] => current.user[2] => OwnerOfSharedDir ) ; limit ""; offset ""

When I login as (OwnerOfSharedDir), OCR works fine.

Is this reproducible or shall I do some more tests and provide more info here?

Bug report

Expected Behavior

I should be able to keep using Nextcloud even if the app is broken.

Current Behavior

It's impossible to use the Files app

Possible Solution

Steps to Reproduce (for bugs)

1. Enable app

Context

Add exception handling to not break Nextcloud when a serious issue occurs.

As stated here: https://github.com/tesseract-ocr/tesseract/wiki#running-tesseract
tesseract also supports multiple languages to process for.

Include such a behaviour in the app.

Should be Empty parameters passed instead of Empty passed parameters.
You don't say Leere übergeben Parameter in german either ;)

OCR 2.0.0

Expected Behavior

Mark a folder and say OCR it

Current Behavior

Cannot OCR a folder

update the travis.yml for mysql. first the mysql service has to be available in the trusty beta of travis.

New release

Have a new branch available which is ready for the latest nextcloud 12.

For example there is a new feature available:
nextcloud/server#3151

Hey guys,
first of all. The nextcloud ocr plugin is great and works fine. Thank you for your work.

Did you think about an option to replace the original file during ocr process? Every time I do this I delete the old file and rename the new one.

Possible solution:
I would appreciate an option in the plugin settings or somewhere else to automatically replace a file when processing ocr. In case of an error or bad result e.g. I would be able to restore the orginal file via NC history feature.

Bug report

Expected Behavior

After a file was selected and the delete action is clicked (in the top action bar). The file action bar gets hidden and the file information sorting is available again.

Current Behavior

The ocr icon and menu option is still available and does not get disabled.

Possible Solution

maybe hide it after the events of the other actions fired?

I have a queueing solution in mind (3rd party) which could allow to cue the tesseract processing for multiple files.
It could run in background and use the Webdav to upload it to the owncloud.
Feedback for the status should be available. (Websockets maybe)

Bug report

Current Behavior

After extracting the current master version of OCR to nextcloud/apps/ocr/ on my Nextcloud 10.0.1 installation, it appears in the Apps section under "Not activated" like this:

[object Object],[object Object] 1.0.0
von Janis Koehr (agpl-lizensiert)

I can enable and use OCR just fine, but as soon as it is enabled, the "Activated" page of the Apps view does not load anymore (endless loading animation).

After disabling the OCR app on the command line (with occ disable:app ocr), the "Activated" page works again.

I took a quick look at the OCR app code, but couldn't find the reason for this behaviour myself.

Log File Content (nextcloud/owncloud.log of the "data"-directory)

Nothing that looks like it has to do with this issue.

transifex setup required.

Scrutinizer awaits the code coverage very long and runs into a timeout. Maybe change the behaviour of travis once again in order to get this right.

Also: change the timeout time to 10 minutes.

I probably should have added this to the other issue (oops).

I forget the exact error but since you are specifying multiple processes you have to specify process_name This is what worked for me: process_name = %(program_name)s_%(process_num)02d

And this is the output of servervisorctl status:
myworker:myworker_00 RUNNING pid 2223, uptime 0:12:02
myworker:myworker_01 RUNNING pid 2240, uptime 0:12:02

Inside a pdf viewer (acrobat reader, or pdf.js in the browser), you cannot search for a phrase of multiple words. The phrase matches nothing even when it is in the document.

Bug report / Feature request

Expected Behavior

When the document contains, for example, "Breakfast menu", when you click the search icon (magnifying glass) and enter text "breakfast menu", it should match the text and find it.

Current Behavior

It olny matches one word. For example, it matches "breakfast", or it matches "menu". If you try to search for two words, it fails to find a match, even when the two words are clearly together on the same line, in the document!

Possible Solution

Possibly take a look at the parameters or settings for tesseract-ocr and see if it can be made to connect words which are on the same line, into the same continuous text line.

Steps to Reproduce (for bugs)

1. Upload a scan of a page of text in pdf format.
2. Run the ocr on it.
3. Open the _OCR.pdf version of the pdf file which contains the recognized text.
4. Click the magnifying glass, enter text for two adjacent words on the same line. Search fails to find the two words. It finds only one word at a time.

Context

Searching for only one word at a time is awkward and time consuming.
