biblatex defines two refsections if I print two bibliographies
Woe is me, I maintain my alma mater's thesis document class and template: technion-iit-thesis.
In theses at the Technion, it is required to produce a list of publications of results covered by the thesis, which I achieve through the printing of a (mini-)bibliography, according to a suggestion on TeX.SX from a while back the code for which is listed below (cautioning in advance it's ugly code and I'm not very good with LaTeX). It uses a refsection command within a refcontext, and somewhere inside there's a \printbibliography. At the end of the thesis, the 'regular' bibliography is printed usign a plain \printbibliography command.
The problem I'm encountering is that, in the document .aux file, I get two labels with the same name:
\newlabel{refsection:1}{{}{5}{}{Doc-Start}{}}
\newlabel{refsection:1}{{}{}{}{Doc-Start}{}}
My complaint is one of two things: Either I should not be getting a second label with the same name (after all, it's a different refsection, right?), or alternatively, the documentation should tell me how I can suppress the generation of the label, or control the label name etc.
That is - unless I'm getting things totally wrong and I should be doing something else entirely.
PS - This started happening not a long time ago - somewhere between 3 years and a few months; I have not had to perform any maintenance work recently. Before that time, my code was essentially the same, and I would not get warnings about duplicate labels. I'm sorry I can't bibisect when this started occuring more precisely.
My code for the mini-bibliography:
\defbibenvironment{pubinfo}
{\list
{}
{\setlength{\leftmargin}{0in}%
\setlength{\rightmargin}{0in}%
\setlength{\itemindent}{-\leftmargin}%
\setlength{\itemsep}{\bibitemsep}%
\setlength{\parsep}{\bibparsep}}}
{\endlist}
{\item}
\AtEveryBibitem{
% For front-page bibliography remove url and doi.
\ifkeyword{pubinfo}{%
\clearfield{url}%
\clearfield{doi}%
}{}%
}
\newcommand{\preparebutcheredbibliography}[1]{%
% Set the keyword "pubinfo" for the references in the front page bibliography

\DeclareSourcemap{
\maps[datatype=bibtex, overwrite]{
\map{
% https://tex.stackexchange.com/a/516673/5109
\step[fieldset=ABSTRACT, null]
\step[fieldset=KEYWORDS, null]
}
\map{
\perdatasource{#1}
\step[fieldset=KEYWORDS, fieldvalue=pubinfo, append]
}
}
}
}
\newsavebox{\butcheredbib@box}
\newcommand{\butcheredbibliography}[1]{
%\makeatletter
\ifdefined\butcheredbib@pubinfo
\else
\begin{lrbox}{\butcheredbib@box}%
\begin{refcontext}[sorting=none]
% See: https://tex.stackexchange.com/a/171153
\begin{refsection}[#1]
\nocite{*}
\begingroup
\def\bibfont{\footnotesize}
\begin{minipage}{0.9\textwidth}
\printbibliography[heading=none,env=pubinfo]
\end{minipage}
\endgroup%
\end{refsection}
\end{refcontext}
\end{lrbox}%
\fi
\begin{center}
\par
\fbox{%
\usebox\butcheredbib@box%
}%
\end{center}
\global\def\butcheredbib@pubinfo{}
%\makeatother
}
Can you show us a short example document that reproduces the issue, please?
