Description Timur 2021-08-31 11:58:33 UTC
In bug 109120, Mailmerge for individual documents was fixed to start filenames from 1 (one), not 0 (zero), for using Mail Merge toolbar.
Same problem with another approach, using simple File-Print. 

1. make a merge document or use ODT attachment 166250 [details] from bug 119942
2. save ODS attachment 166251 [details] to the same folder
3. open ODT and File-Print
4. Yes to Do you want to print a form letter.
5. Output: File - Save as individual documents, turn off "Generate file name..".

Reproduced: name0, name1....
Expected: name_1, name_2.....

Apart from fixing 0, there should be underscore just to be consistent with toolbar approach.

Note: I didn't check previous versions, but I doubt this is a regression, rather Inherited.

Leaving the Generate name from database option turned off asks for a custom file name, which gets numbered starting from 0 and no underscore between the entered name and the number.
Comment 2 Justin L 2021-09-22 11:16:54 UTC
This numbering comes from dbmgr.cxx
 aTempFile.reset( new utl::TempFile(sLeading, sColumnData.isEmpty(), &sExt, &sPrefix, true) );

where sColumnData.isEmpty() /*which means this is not a generated name*/ provides _bStartWithZero.

So to do this, we need to extend TempFile and SequentialTokens to accept provided starting values instead of automatically starting with 0.  (Well, on the other hand we could just start EVERY use of the general utility TempFile at 1, but that is not a very targeted case and may break many assumptions...)
Comment 3 Justin L 2021-09-22 19:13:52 UTC
Another easier option would be to always set _bStartWithZero to false.

In this case it would export
file.odt
file1.odt
file2.odt
...

But I don't think that would be terribly helpful because then 1 is actually the second record. Yeah - that really isn't different from the zero case except that we don't have an explicit zero. So bad idea.

P.S. CppunitTest_sw_mailmerge fails if starting m_value(1) instead of zero.

proposed fix http://gerrit.libreoffice.org/c/core/+/122489 tdf#144215 mailmerge: start individual document at 1, not 0

Adding the _ can be added separately.
Comment 4 Justin L 2021-09-23 10:00:57 UTC
Adding the _ is probably too tricky to be worth it since a simple attempt to do so breaks lots of unit tests.

At the time of defining the filename, it cannot be known whether a number will be used or not. So really it would require adding another variable to TempFile to allow for an optional a numberPrefix. That kind of complexity would require a more compelling reason.
Comment 5 Timur 2021-09-23 11:34:52 UTC
Justin, thanks for looking into this. If numbers are ok, underscore can be disregarded (while not clear how it works in bug 109120).
Please see discussion at bug 14448 and if you think that there should be a single code for mail merge.

bug what?

The mail merge wizard seems to design a name without worrying about whether it will trample over existing files. This wizard very carefully makes sure it creates a unique file. So you are NOT guaranteed that the first record will be file1.odt.  It could be file17.odt if 1-16 already existed.

So this is a completely different (and very generic) code path we are dealing with.

Sorry, bug 144483.
Comment 8 Justin L 2021-10-01 17:57:45 UTC
Based on review "Last time I did something like this, some people complained about failing scripts via UNO MM. You'll probably get new bugs as a regression." I abandoned https://gerrit.libreoffice.org/c/core/+/122489.
