The problem is due to the use of the mathpazo package because
it defines the macro \f@family as "ppl\n", i.e., it appends a
newline character at the end. Now, the "\if" TeX primitive
expands its arguments for comparing them and the newline causes
a "missing \begin{document}" error. Instead of complicating the
code to account for this, it is better using the ifthen package.
The log file generated by latex can contain strings encoded in
whatever supported encoding. Instead of guessing the encoding,
it is better to open it in binary mode and then performing the
necessary comparisons as "bytes". In order to do this, the
strings are encoded in utf8, so that, for example, b"pythön" is
encoded as "pyth\xc3\xb6n" (7 bytes). Of course, this means that
we can only successfully perform comparisons with ascii strings.
However, this is what we actually do, as we only search for
ascii strings in the log file.

Unfortunately, stat.st_ino returns 0 on Windows, at least on Python 2.7, so we can't use that way of telling when we're seeing the same directory again. Surely the real pathname should work.

In python 3 the colors need to be strings and not bytes:
This was the equivalent of
>> print("%s" % b"1")
"b'1'"
since the colors were bytes the call to dvipng was something like
dvipng -Ttight -depth -height -D 115 -fg "b'rgb 0.937255 0.941176 0.945098'" -bg "b'rgb 0.137255 0.149020 0.160784'" "lyxpreviewxBJEqm.dvi"
Note the "b'rgb after both -fg and -bg that wrecked havoc and thus dvipng failed. That was the difference between python2 and python3 calls.

Nix (https://nixos.org) is a Unix package manager, which can be used to
install LaTeX on macOS. A peculiarity of Nix is that all packages are
installed into separate directories and the actual directory tree is
then constructed via symlinks.
This interacts badly with the way LyX currently detects files in the
TeX setup, because TeXFiles.py does not follow symlinks. Therefore,
almost nothing is found when using LyX together with Nix’ LaTeX.
Patch from Michael Roitzsch.

The fixes are simple and on line with the changes made during
the 2.3 development. It was an oversight to leave them out.
With this commit all the python scripts should be supported by
python 2 and 3.

Now layouts can specify other layouts that should be nested in and
after the current one (if the layout is switched from the current one
and if it follows a paragraph in the current one).
This is particularly useful for things such as the beamer frames, where
particular layouts are practically always nested.
This is a backport from master, including all fixes.
The current spelling is not strictly wrong, but flagged as unusual or
historical by some authorities. It is also found fault with many
spell checkers. Thus we decided to move to the more standard "-ible"
form once and for all.
See #10678 for discussion
This part covers the most tricky part: the internal naming.
Translations and layouts will follow.
This will all also all be backported to 2.3.x, for the sake of backwards
compatibility (cherry-picking).

In 1a26f9b26c, all strings in the context of regexes and
comparisons have been converted to byte-like objects for python2/3
compatibility reasons. This has not been considered in the later
commit 5c54557350, which makes layout2layout break with
TypeError: can't concat str to bytes.
(cherry picked from commit 8fecdfc473)
Remove the trimming operation on LabelString, LabelStringAppendix,
EndLabelString and LabelCounter. This trimming meant that quotes
strings were not preserved, which is wrong.
To preserve layouts, the Layout format has been updated to 64, so that
layout2layout can remove extra spaces on existing strings, which
ensures that behavior is unchanged for old layouts (courtesy of rgheck).
It is now possible to re-add spaces in label strings where it makes
sense.
Fixes bug #10723.

The inkscape command was hardcoded, but it seems that we need the full
patch on Windows. Therefore we check in configure.py if inkscape is
installed and pass the proper name (and possibly path) to the scripts.
Should address problems mentioned in #10679
This fixes an error in the preview generation with polyglossia
and bidi that prevents snippet generation (and consequently also
"math as image" xhtml output).
Fixes: #10716.
Due to the peculiarities of Windows, it may happen that
pdftocairo is built without png support when compiled on this
platform. Unless explicitly requested (maybe for some peculiar
application and certainly not for usual distros), this is
highly improbable to occur on other platforms.
1.) Handle also 'LatexCommand inputminted' in lyxStatus.pm
2.) Add '-shell-escape' to the appropriate converters.
This applies only to the ctest-environment iff calling
the script 'prefTest.pl' in the build directory.
If we call parser.parse_args(), thus with no arguments, the parser uses
sys.argv (because that is the default). We should pass argv since that was
the purpose of handling argv in the main function.
We pass argv[1:] since when parsing the arguments we always ignore the name
of the program.
Use the full power of argparse to declare the default value of the end_format.

Remove support for python 1.x (really)
This code has not been used for a long time, probably never, since some code
above requires at least python 2.4 to work.
I got to this code by running futurize from python-future. There are no
significant warnings, mostly are related with the division but since
we are dividing floats there is no change between python 2 and 3.
python 2 does not allow to declare a string as raw byte so we double
the backslashes and remove the r preffix
python 3 accepts rb"..." meaning a byte string that is raw. In this context
raw means that the backslash does not has any special meaning and thus it
is not escaped. This is usefull together with regular expressions where the
backslashes are special.
In the worst possible case, like this one, we must use 4 backslashes to represent
one in the regular expression...
