Issues with CSV upload
Hello,

I'm running MediaWiki 1.31.1 on Mac OS and installed the "Data Transfer" extension according the instruction. From the "cheese" example I generated a CSV file and imported it via special page "Import CSV". The import worked well. Four pages were generated.

After this initial test, I deleted the four newly created 'cheese'-pages and uploaded another CSV-file. After importing this, the just deleted four 'cheese'-pages reappeared again. I needed to delete them but after uploading another file the showed up again.

Could you please be so kind and give advice? Thanks!


 * That's very odd... Data Transfer uses MediaWiki "jobs" to do all the page creation, so my only guess is that these jobs are not getting properly deleted after being run. If you have command-line access, try going to the main wiki directory and calling "php maintenance/runJobs.php", and see what happens. If you run it more than once and the same jobs get run, that's definitely a problem. Yaron Koren (talk) 21:47, 13 November 2018 (UTC)


 * Thanks for your reply. I needed some time to figure out how to work the Mac OS terminal. As adviced I move to the root of my wiki and entered "php maintenance/runJobs.php". After repeated calling, I received this:

 * This is not a Data Transfer issue - I did a web search on that error message and found this, among other things. Does that help? Yaron Koren (talk) 15:20, 21 November 2018 (UTC)


 * Hello Yaron, I followed your hint and started a google search as well and found some possible solutions (1, 2, 3, 4, 5, 6, 7, 8). It seems that some adjustments in Local Settings may be of help:

 * None of this worked for me. Unfortunately this type of work is out of my competences. Since I also have problems with some other extensions (see here and here), it might be a specific problem with my system. Thanks!

Fixed problem with processing Utf-8 characters
When I tried to import Unicode characters, I was getting garbage. This problem was fixed by changing the file "./extensions/DataTransfer/specials/DT_ImportCSV.php"

I commented out the code between lines 119 and 129, changed it to the following: After the line is read with "fgetcsv", the line does not need any additional processing. Mediawiki can handle a line with unicode text fine. I also changed the delimiter character, because I was having issues with the comma character (it was too common in the data I was importing). That should actually be a GUI option, but that is another issue. Zzmonty (talk) 20:25, 7 August 2018 (UTC)

My wiki is currently bugged. I think it may have something to do with the same info being submitted twice as a csv import.

As a side effect I'm unable to save pages as well as a few other things.

 * Hi - I would delete the contents of your "job" database table - that should at least take care of these current problems. Then, if you're ready to do the import thing again, it might work better now that you've updated all the software... but if you get the same problems, please let me know.

Import CSV error, line break SOLVED
In case you use Mac OS X, make sure you save your CSV file with Windows line break format. I have Excel and TextWrangler (just another text editor). I used Excel to edit the CSV file. Then I reopened the file in TextWrangler and save as, specifying that it uses Windows line breaks (CRLF) (as per the CSV specification linked to on the extension page), rather than Classic Mac (CR).

--Tommyheyser (talk) 22:19, 9 March 2014 (UTC)

That's very helpful! It's odd, a linux open source system using the DOS convention, but I suppose they do it deliberately.

In vi you need to type:


 * %s/^M/^M^J/

Incidentally, this isn't the right place to ask, but, is there a way to have vi instead of the editor mediawiki uses as a standard?

Fustbariclation (talk) 05:13, 10 March 2014 (UTC)


 * Tommyheyser - thanks for diagnosing that issue; I just added a note about that to the documentation. Fustbariclation - I believe CSV files saved with both Windows and Linux are handled fine; it's only Mac (apparently) that requires special treatment. (It could well be that the Data Transfer code could be modified to handle the Mac style as well; I haven't looked into it.) Yaron Koren (talk) 21:54, 10 March 2014 (UTC)

How to add text at the top the page while keeping current page content, ?
Thanks,

Nicolas NALLET (talk)


 * If you choose the "append" option, it will add content to the bottom of the page; there's no way to add content to the top of the page, as far as I know, but you could probably easily change the "append" behavior in the code. Yaron Koren (talk) 14:40, 25 March 2014 (UTC)

Extension breaking /mw-config/ [SOLVED]
Hi Yaron,

Firstly, I must say that I really admire your work and use several of your extensions. Bravo!

Two years ago I used DataTransfer successfully on an earlier incarnation of my website. I was then using it with the Semantic bundle which is impressive, but the bundle was unsuited to my needs and I no longer use it.

Today I upgraded my site to Mediawiki 1.24 and coincidentally installed the DataTransfer extension soon afterwards. I have been trying to get Special:ImportCSV and Special:ViewXML to work but without success so far. Both just seem to hang. Import CSV responds with "Importing... 2 pages will be created from the CSV file" but it does not create either of the new pages. Two years ago Special:ImportCSV worked okay.

Later, when I visited the config page - eg. http://www.example.com/mw/mw-config/index.php - I found that DataTransfer did cause an error:

Warning: include_once(/languages/DT_LanguageEn.php) [function.include-once]: failed to open stream: No such file or directory in /home/mysite/public_html/mw/extensions/DataTransfer/DataTransfer.php on line 98

Warning: include_once [function.include]: Failed opening '/languages/DT_LanguageEn.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/mysite/public_html/mw/extensions/DataTransfer/DataTransfer.php on line 98

Fatal error: Class 'DT_LanguageEn' not found in /home/mysite/public_html/mw/extensions/DataTransfer/DataTransfer.php on line 102

I am hopeful that the /mw-config/ related error may in someway be symptomatic of the reason that I cannot get the extension to work.

Thanks in advance for any advice.

 * Are you using the latest version of Data Transfer, 0.6? The line numbers make it seem like you're using an older version. Yaron Koren (talk) 12:45, 26 September 2014 (UTC)


 * Yaron, I have just found that the Download Snapshot, using the Special:ExtensionDistributor for Mediawiki Release 1.23, was downloading Version 0.5. I have now downloaded Version 0.6 using the adjacent (Git master) link in the Infobox. It is still breaking Config however, but with different line numbers now:


 * Warning: include_once(/languages/DT_LanguageEn.php) [function.include-once]: failed to open stream: No such file or directory in /home/mysite/public_html/mw/extensions/DataTransfer/DataTransfer.php on line 106

 * Fatal error: Class 'DT_LanguageEn' not found in /home/mysite/public_html/mw/extensions/DataTransfer/DataTransfer.php on line 110


 * Special:ViewXML is now working with Version 0.6 installed. I have not tried ImportCSV as I have a lengthy BOT running at present, but my 'spider senses' guess that ImportCSV will probably work now.


 * By the way, I incorrectly said in my first post I had upgraded to 1.24; I meant to say I had upgraded to 1.23.4.


 * Regards, Cruickshanks (talk) 15:43, 26 September 2014 (UTC)


 * Oh, okay. I looked through my emails and realized that I had a an email discussion with someone about this very same problem a few weeks ago. We weren't able to figure out the underlying cause, but were able to fix it by just commenting out line 77 of DataTransfer.php, which reads "dtfInitContentLanguage($wgLanguageCode);". It's fine to do because the language stuff is only used for a few minor features, like XML grouping, that you're probably not using. Yaron Koren (talk) 16:40, 26 September 2014 (UTC)


 * Thanks Yaron, that fixed it. Regards, Cruickshanks (talk) 18:49, 26 September 2014 (UTC)

Multi-instance templates not preserved in output
If you import a file and update fields in the base template of a page it removes any multi instance templates embedded within and replaces them with the text "Array" this can be solved quite easily in DT_PageStructure.php public function toWikitext { if ( $this->mIsTemplate ) { $wikitext = '";      return $wikitext;     } else {	return $this->mFreeText;     } }

XML Import Only Imports 2 Pages
Hello:

I have an XML file coded to create 80 new pages.

When I try to do the import, I get a message saying:

How do I create all 80 pages at once?

Nothing exported

Fustbariclation (talk) 09:25, 11 June 2015 (UTC)


 * Are you trying create a "copy" of property pages, pages with properties on them or maybe both? If so you should be fine when you use . This will export the actual page content, it does not matter what is on them. You have to make sure you export everything you need for it to work on the other wiki, including categories and templates. This is why categorising pages is important :) it makes duplicating pages easier. When you import the resulting XML on your destination Wiki it will covert the page content back to properties and values. Regards, --Felipe (talk) 09:50, 11 June 2015 (UTC)

Nothing imported
Hello,

each time i try to import pages it simply does not work. It tells "0 pages will be created from the XML file". Mediawiki version 1.24.1.

Here is a pastebin in order to see if you can help me.

http://pastebin.com/kdS3K2Ci

Thanks.

P.D: Could it be because of language? Perhaps it does not simply understand spanish, but that would be really extrange, as extension itself gave that XML to me.

--00Maiser00 (talk)


 * I think I made a bad mistake by having the XML field names be translatable, instead of just always being in English. For the case Spanish, I think the issue is that the translation for "ID" is "Id." - I think the "." is causing the problem. It could be that the accents in "Páginas", etc. are also a problem. If it's not too much trouble, I would suggest replacing all the Spanish field names with their English-language equivalents (you can find them here), which will hopefully work. And I probably need to change that internationalization thing. Yaron Koren (talk) 17:11, 3 August 2015 (UTC)

I just made a program to translate all these tags from spanish to english, still not working. It may be because i have putted some tag incorrectly. Could you provide me with a viewxml in english where i can see all elements please?

Moreover, this is what is actually not working for me (as an example, trying to import forms).

http://pastebin.com/ZFFULXdi

Could it be because it is trying to read in spanish, but does not understand it? I have tried with other pieces of xml (simple ones) and is still not importing, no matter the language i use.

--00Maiser00 (talk)


 * It should be "Free_Text", not "Free Text" - maybe that's the issue. Yaron Koren (talk) 00:21, 17 August 2015 (UTC)

I changed that and it is still not working. Could you send me some text which can be confirmed is working so i can test if it is because of the syntax or simply because a problem in the import when the wiki is in another language?

--00Maiser00 (talk)

Any change yet for the language? If it is related to vocabulary, i guess it is regarding something which can not be changed in the xml generated document. Perhaps it is because of "user hidden" vocabulary in the import or something? I am pretty surprise i am the only non english user which is talking about this issue :S.

EDIT: I can confirm the problem is not solved changing vocabulary to english, i tried importing elements from your example page: http://discoursedb.org/wiki/Special:ViewXML And it still did a 0 import.--00Maiser00 (talk)

Feature request evaluation level (nested templates problem)
Hi,

using Data Transfer 0.6.1 the problem arises that in the 1st template level the value of a parameter can have further nested templates (2nd level). The 2nd level is also transformed to xml but embedded in partially Wiki-parsed HTML from the 1st level value, that is: plain text becomes &lt;p> (or &lt;ul>, &lt;dl> etc.), the value is then regarded as Wiki code to be parsed. See the XML output examples. Without the nesting templates it would transform to: But with nesting templates it parses each 1st-level-value partially that is split by a 2nd-level-template:

Why is the value in the 1st level (that has nested templates in it) partially wiki parsed? Could there be a feature to not evaluate that deep? Do you know what I mean? I did not expect that the 1st-level value, that embeds 2nd-level-templates, is parsed partially. Any solution to that?

Kind regards --Andreas P. 11:36, 18 May 2016 (UTC)


 * That sounds like a bug. Yaron Koren (talk)
 * Well, possibly not: I saw just now that there are  and   that prevent parsing. The default setting   causes this (for me unexpected) behaviour. --Andreas P. Icon_External_Link_E-Mail.png 14:22, 18 May 2016 (UTC)

Schema file for ViewXML import?
I have hundreds of non-wiki XML files, each containing thousands of entries which I'm trying to import as separate pages in my wiki. This extension seems like the right way to go. I'm trying to create an XSLT (Using the 30 day free trial of Altova MapForce because I have no idea what I'm doing) to convert the XML from the schema it's currently distributed in to the format generated by the Data Transfer ViewXML page. Is there an .xsd schema file available for the import? Thanks. Tcrimsonk (talk) 19:09, 29 June 2016 (UTC)


 * No, unfortunately. Yaron Koren (talk) 02:25, 30 June 2016 (UTC)

Best way to escape commas and double quotes in creating CSV to import?
Related to my question above, it would probably be easier for me to convert my existing non-wiki XML files into CSV for import rather than trying to match your XML schema. However, the existing XML contains fields with text including both commas and double quotes. How should I indicate which of these are deliberate delimiters in a way that Data Transfer will recognize? Thanks again. Tcrimsonk (talk) 19:09, 29 June 2016 (UTC)


 * I agree that CSV would probably easier than XML. You should just look up how to handle commas and quotes in CSV; I think they both require extra double quotes. Yaron Koren (talk) 02:33, 30 June 2016 (UTC)


 * Thanks; from what I've found, there are various ways to handle commas and quotes in CSV, and the choice depends on what program is going to be interpreting/processing that CSV. So I would still need to know how Data Transfer (or perhaps just MediaWiki in general) handles them.  I'll try a CSV import with all fields encased in double quotes and see how that works.  I'll reply back here once I know.  (Unless someone else has a suggestion.) Tcrimsonk (talk) 03:25, 30 June 2016 (UTC)

Automatic/Bot/Script based Importing?
Is there any way to monitor a given directory, and automatically import any XML/CSV files that appear there? Or is there a command line way to invoke the import? Tcrimsonk (talk) 03:25, 30 June 2016 (UTC)


 * Unfortunately, no - Data Transfer doesn't provide an API. You would need to create a custom bot/script to do it, I think. Yaron Koren (talk) 14:47, 30 June 2016 (UTC)

If the extension should be extended with automatic importing, what would be the way to go? Would a maintenance script that reads a file and does the import be a simple way to do that?--AdSvS (talk) 12:03, 26 October 2016 (UTC)


 * A built-in import script does sound like the easiest approach, yes - I hadn't thought of that. Yaron Koren (talk) 17:14, 26 October 2016 (UTC)

After creating a csv-file: Title,Cheese[Country],Cheese[Texture],Free Text Mozarella,Italy,Semi-soft,It's good on pizzas! Cheddar,England,Hard/semi-hard,"Often sharp, but not always." Gorgonzola,Italy,"buttery or firm, crumbly","salty, with a ""bite"" from its blue veining" Stilton,,"",needs more data and a Template:Cheese: This cheese is from and the texture is generally

... all I see is: "Importing... 4 pages will be created from the CSV file."

My logfile shows these Exceptions and Errors: (shortened ) [exception] [93065002f4979874bc4e15f3] /Special:ImportCSV  DBUnexpectedError from line 2852 of /var/www/html/mediawiki/includes/libs/rdbms/database/Database.php: MWCallableUpdate::doUpdate: Cannot flush snapshot because writes are pending (WikiPage::insertOn, Revision::insertOn, Revision::insertOn, WikiPage::updateRevisionOn, WikiPage::updateRedirectOn, RecentChange::notifyNew). salty, with a "bite" from its blue veining requestId=93065002f4979874bc4e15f3 (id=224,timestamp=20170225134852) t=121 error=DBUnexpectedError: Invalid atomic section ended (got WikiPage::doCreate).

But where are the 4 pages??? No pages have been created. And why is it 4 pages? I would expect 1 page ...

What am I missing? Any help is highly appreciated! TieMichael (talk) 07:49, 26 February 2017 (UTC)


 * I hadn't seen the error "Cannot flush snapshot because writes are pending" before, so I did a web search on it, and I found some bug reports like this. This looks like a bug in MW 1.28.0, which I assume is what you're using. Hopefully it will get fixed soon.
 * It's four pages because each row gets turned into a page. Yaron Koren (talk) 14:08, 26 February 2017 (UTC)

UTF-8 not recognized
In a wiki with Data Transfer 0.6.1 I could correctly import an UTF8 formatted CSV with special characters. On the same wiki, I upgraded to 0.6.2 and it results in creaton of a wrong pagename, because the special character is no longer recognized. Seems to be a bug from version 0.6.1 to 0.6.2. UTF 16 works, though. --Krabina (talk) 08:59, 2 March 2017 (UTC)

I can confirm what Krabina reports : utf-8 csv file content is not correctly imported either in wiki page content (accented characters are mangled). utf-16 just works. ( Data Transfer 0.6.2/MW 1.27.3 )

It's the same here with V 1.0 (bf885af) / MW1.31.1. Carchaias (talk) 12:21, 23 November 2018 (UTC)

"0 pages will be created from the XML file"
Hello !

I've got a problem with DataTransfer import from XML, when I import an XML file with "Special:ImportXML" it show me that error message: Expected 'Pages', got 'pkg:package'Expected ,got Expected , got Expected , got Expected , got 

"0 pages will be created from the XML file" And the import does not work, anyone know or have a clue to fix it ?


 * The Special:ImportXML page requires that the XML be in a specific XML format. I'm surprised now to see that the documentation page doesn't actually describe the format, but you can see an example of it here. Though the "import" version of the format is slightly different - you can see the differences explained in the 2nd paragraph here. Yaron Koren (talk) 14:40, 9 May 2017 (UTC)


 * Thanks for the answer i'll try it :)

Hi it's me again :D I created XML files with the right format, but now I've this : Import in process, 1 page will be created from XML file But it doesn't work, I tried many importations with different syntax with no results. I tried to let it load during 1 hour but no results too. I can't find where is the problem :/


 * Maybe it's still in the job queue? See the first item here. Yaron Koren (talk) 17:40, 11 May 2017 (UTC)

1.28.* change in $wgRunJobsAsync a problem? [SOLVED]
Recently upgraded to 1.28.1 and can no longer get CSV imports to work. The import page seems to work and read the file as it always did, but no pages are added. Would the change in the default of $wgRunJobsAsync to false cause this? Thanks! --DHillBCA (talk) 17:37, 25 May 2017 (UTC)


 * Could be. Try changing that setting's value in LocalSettings.php? Yaron Koren (talk) 18:14, 25 May 2017 (UTC)


 * Adding the setting worked. Thanks! --DHillBCA (talk) 14:13, 30 May 2017 (UTC)

Xml import not creating all pages
I'm trying to use this extension to import XML of new pages. I followed the template exactly as what is exported from "View XML" but no matter how many pages in my import XML file, it doesn't import all of them. If, for example, I have 30 pages to import, it may import 15, or if it's 15 it may import 12. Running the exact same XML file again will import the missing pages. Any idea what's going on? I've increased run rate to 50 and also run the runJobs.php from the command line but the remaining pages are still missing until I import the exact same xml file again.

A second question is that I need to import about 7000 pages. Any tips or tricks how to do this efficiently? Is there a rule of thumb for the most pages that should be imported at once? or a limit on the length of a file to import (# lines or KB)?

--Anrake (talk) 01:50, 18 June 2017 (UTC)

Correction: it seems the pages show up eventually, but is there anything I can do to speed the process? runJobs is not creating them and run rate is set much higher.

--Anrake (talk) 04:05, 18 June 2017 (UTC)


 * It's good to hear that all the jobs are getting run - otherwise it would be a much bigger problem. I confess that I still don't know much about the inner workings of how jobs are run, but: if you're using MW 1.28 or higher, the section above may be helpful. If not, your high job run rate may ironically be making the problem worse, by overloading the system and leading to jobs that do not get run; I would try reducing the rate to 1 and running runJobs.php. Yaron Koren (talk) 02:13, 19 June 2017 (UTC)


 * Thanks I will give that a try this weekend. I did try fiddling with async before writing originally but that didn't help either.  Anrake (talk) 11:42, 22 June 2017 (UTC)


 * Actually that took care of it. Once I set the run rate to 5 runjobs.php made all the required pages instantly. --Anrake (talk) 13:12, 22 June 2017 (UTC)


 * Great! And that's good to know. I just added a note about that to the documentation. Yaron Koren (talk) 19:11, 22 June 2017 (UTC)

Speed
When uploading a spreadsheet of around 500 lines it takes several minutes for MW to come back. The request itself (i.e. sending the file to the server) finishes reasonably fast, but for the answer to be generated takes on the order of 5 to 10 minutes minutes. Does anybody have similar experiences? --F.trott (talk) 08:10, 7 July 2017 (UTC)

Multi templates & ImportCSV
Hi Yaron,

I'm testing out the ImportCSV routine of Data Transfer. One thing I noticed is that multi-templates seem to be not supported yet (only last values are stored(. I found a similar post reporting this earlier. Is this something you have found a way around for and if so what would that be? Or would the best way to work around this by following the suggestion posted at: https://www.mediawiki.org/wiki/Extension_talk:Data_Transfer/Archive_2008_to_2013#Multiple_templates_.26_ImportCSV

Thanks, --Albert Ke (talk) 18:13, 7 July 2017 (UTC)


 * This still isn't supported, unfortunately. That workaround may be the best way to do it. Yaron Koren (talk) 18:23, 7 July 2017 (UTC)

How to have line breaks inside each article
Lets say I want to have a paragraph break or line break within the article. Using will do the trick but it will show when editing the article.--Spiros71 (talk) 17:13, 8 July 2017 (UTC)


 * You can just have line breaks, in the CSV or XML... Yaron Koren (talk) 13:41, 9 July 2017 (UTC)

Section edit links only show template tags, not the included text
I am not sure whether there is a MW setting for that, but for text imported with templates and Data transfer, when trying a section edit, I only see the template and not the actual text that has been imported in that page. The only way to see the actual text is to use the page edit link. --Spiros71 (talk) 13:41, 16 August 2017 (UTC)


 * Is this a Data Transfer issue? Or would the same problem exist if the page were created in any other way? I'm not sure I understand the problem. Yaron Koren (talk) 14:38, 16 August 2017 (UTC)
 * No, it is not, but I thought you may know the answer. Here is an image: https://www.translatum.gr/test/test2.png --Spiros71 (talk) 04:38, 17 August 2017 (UTC)


 * Alright. I'm guessing that the issue is that the section header is defined in the template itself - meaning that the section can't really be edited on the page. If that's true, the best course of action is to add a " " line to the template, so that those "Edit" links don't appear, since they just cause confusion.

Hebrew words import problem
Although the import apparently worked and new words are listed in the category, when clicking any of the links, it will show "There is currently no text in this page". Is this some sort of directionality issue? Searching the word is displayed in search results, but when clicking on it, again the same page. --Spiros71 (talk) 05:28, 26 August 2017 (UTC)


 * That's very strange. What do you see when you go to "action=history" or "action=edit" for those "nonexistent" pages? Do the pages actually have the right text in them? Yaron Koren (talk) 12:44, 27 August 2017 (UTC)
 * "There is no edit history for this page." and "Creating". It is even stranger, that some terms have been imported OK and display OK. It makes me thing that MW does not like certain Hebrew characters? For example, these entries:
 * 1, 2, 3, 4 work OK.


 * I would try running the import again - maybe it's just a matter of some import "jobs" not being run. Yaron Koren (talk) 12:09, 28 August 2017 (UTC)
 * I had already done so (even with the "Overwrite existing content" option). Although other jobs are run just fine, these (if there are Hebrew titles already entered in the past), apart from the initial "imported x successfully" notice, do not even show in the Recent Changes. But, it is not that they did not get imported at the first place, apparently they are somehow only "entered" in the search system (and listed in the relevant Category) and not in actual pages. I even thought of trying UTF-16 but the flavours I tried did not work at all (LE/BE without signature using EmEditor). If I manually create any of these pages (I.e. by following a link from the category listing), text is stored OK. --Spiros71 (talk) 16:00, 28 August 2017 (UTC)

Allow import for all users does not work
Hello,

The instruction $wgGroupPermissions['*']['datatransferimport'] = true;

does not work for me. I still get the message : "You do not have permission to import pages from another wiki, for the following reason:

The action you have requested is limited to users in the group: Administrators."

Mediawiki 1.28.0 Datatransfer 0.6.2


 * That's unexpected... do you have that line in LocalSettings.php after the inclusion of Data Transfer? Yaron Koren (talk) 16:36, 8 December 2017 (UTC)

PHPExcel - DEPRECATED .. what to do?
The PHPExcl project [0] says that "All users should migrate to its direct successor PhpSpreadsheet, or another alternative." For new wikis wanting to use the "Data Transfer" extension, what should we do? -Rich (revansx)

[0] https://github.com/PHPOffice/PHPExcel


 * I'm aware that PHPExcel is deprecated, and it would be great if it were updated. Do you know if the current library fails, or if it still works? I haven't tried it in a long time. Yaron Koren (talk) 03:40, 15 March 2018 (UTC)

PHPExcel
Hi Yaron, PHPExcel appears depreciated and they recommend instead PhpSpreadsheet. Is that supported too? Not sure how to either of those on a CentOS/WHM server.--Spiros71 (talk) 10:38, 6 December 2018 (UTC)
