It was possible for errors that occured in the first run to be shown
in the error list after the second run. Now, the errors are cleared
before the second run.
Although I do not have a reproducible example at hand, I imagine
this situation would occur if a rerun is required and there is still
an error after the rerun.
Related to #9765.
Before, the exit code for the first LaTeX run was used to set the
flag, which caused an error to be reported when in fact there was no
error on the second run.
This fix ammends 1dbf0e5a.
The "save-as" part of the bug is fixed by extending the \textclass tag
such that, if a local layout file is used, its path relative to the
document directory is now stored together with the name. If a relative
path cannot be used, an absolute one is used but, in this case, the
document is not usable on a different platform.
The "copy" part is fixed by introducing a new \origin tag, which is
written when the file is saved. This tag stores the absolute path of
the document directory. If the document is manually copied to a
different location, the local layout file is retrivied by using
\origin (which is only updated on save).
This new tag may prove useful also for locating other files when the
document is manually moved to a different directory.
As in the original implementation the files needed for the layout
(for example, a latex class) had to be in the same directory as the
layout file, this directory has also to be added to TEXINPUTS.
Because of our better mechanism for dealing with errors (72c5385f),
the problem described in the comment is no longer possible.
NO_OUTPUT is treated as an error so there will no longer be a
lingering PDF in this case.
As Enrico said, the user might have installed a package that was
missing (in which case the .tex file would not have changed).
Another reason is that changing some document settings did not
automatically lead to a fresh compile after an error (#9061).
Our old mechanism for detemining whether there was an error was to
check if the dependent file existed in the temporary directory. If
it did not exist, that meant it was removed, presumably because
there was an error during compilation. That mechanism cannot be used
anymore because we keep the files around even after error because of
the "Show Output Anyway" button (09700d5b). This commit implements a
more straightforward way of checking whether there was an error in
the previous preview by simply storing the success of last compile
in a buffer variable.
A PDF is often still produced after a LaTeX error.
If there was an error when exporting a PDF, we now give an error
and the PDF (if it exists), where before we gave the error and
not the PDF. The GUI and command line behaviors are consistent:
in the GUI an error is given and the PDF is viewed; on the
command line, a non-zero exit code is given and a PDF is created.
This also solves what was in my mind an inconsistency: if the user
"updated" a document and there was an error, the resulting
PDF would be shown; but if the user viewed a document and there
was an error, the document would not be shown.
Note that this applies to all output formats, not just PDF.

When scanning the LaTeX log, previously we only looked ahead 10 lines
after a "!" line and if we did not find a line number we did not count
an error. This lead to the problem that templates/ACM-sigplan.lyx was
showing a successful export and the PDF was shown (it is still
created despite the error). Now that the exit code of the latex
command is checked (as of the previous commit), an error is correctly
given, but by parsing the log better with this commit, a more
informative error is given.
Increasing the look-ahead to 15 lines leads to correct parsing of
the ACM-sigplan log. The excerpt in the log file where there are more
than 10 lines in-between the "!" line and the line number is below:
! Undefined control sequence.

Another example is posted here:
http://tex.stackexchange.com/questions/231655/lyx-cannot-output-to-pdflatex-for-a-specific-file
Systemcall::startscript returns the exit code of the LaTeX command
that is run, but the return value was not being checked by
LaTeX::run. Instead, we relied on parsing log files. However, this
parsing is not perfect.
The return value is now checked and if the exit code of the command
is non-zero, an enum value is added to the return and the user is
notified of the error.
At a higher level, if the LaTeX command returns a non-zero exit code,
in the GUI a message such as
"Error while exporting format: PDF (LuaTeX)" will be given instead of
"Successful preview of format: PDF (LuaTeX)".
When run on the commandline, lyx -e lualatex example.lyx
will give "Error: LaTeX failed" and a non-zero exit code
where before it gave a zero exit code.
A real example of the bug this commit fixes is LyX's (as of this commit)
ACM-sigplan.lyx template.
Before this commit:
$ lyx -e pdf2 ACM-sigplan.lyx
[...snip...]
support/Systemcall.cpp (288): Systemcall: 'pdflatex "ACM-sigplan.tex"'
finished with exit code 1
$ echo $?
0
Starting with this commit:
$ mylyx master -e pdf2 ACM-sigplan.lyx
support/Systemcall.cpp (288): Systemcall: 'pdflatex "ACM-sigplan.tex"'
finished with exit code 1
Error: LaTeX failed
----------------------------------------
LaTeX did not run successfully. The command that was run exited with
error.
$ echo $?
1
This commit solves two issues:
(1) A PDF from a previous run could have been the result of a command
that exited with error (e.g. sometimes pdflatex still produces a PDF if
it exits with error). If the "View" button were clicked a second time
without changing the .lyx file, then the checksum of the .tex file would
not have changed so LyX would show the PDF (which was created from the
first run that exited with error), and this time LyX would not report
the error (because the parsing of the logs only happens when the .tex
file is compiled).
(2) A myfile.tex that results in no output does not yield a myfile.pdf.
Thus, Any myfile.pdf in the temporary directory will not be overwritten.
Before this commit, the following scenario was possible: LyX runs
pdflatex which processes myfile.tex and no error is given so LyX opens
myfile.pdf. However, it could have been the scenario that pdflatex did
not exit with error and did not create myfile.pdf, in which case
whichever myfile.pdf is being shown is not correct. To see this bug in
action, start a new document, type "abc", view the PDF, delete "abc",
view the PDF (this correctly gives an error that empty output was
created), view the PDF again (this does not give an error because the
checksum has not changed). The PDF shown will contain "abc".
Note that the above also applies to DVI files and that the fix is
general.
The assignment name = sub.str(1) reads from the first argument given to
regex_match(), but previously this was a temporary object which was already
out of scope. This did probably not matter much in practice, but invoked
undefined behaviour, and as we all know this is allowed ton format your hard
disk or kill to your cat, so better fix this.
for possible thread conflicts, of the sort Georg resolved at
6a30211f. I have made static variables const where possible,
and marked cases that looked potentially problematic with the
comment:
// FIXME THREAD
Many of these definitely are vulnerable to concurrent access, such
as the static variables declared at the start of output_latex.cpp.
Suppose, e.g., we were outputting latex and also displaying the
source of a different document.
I'd appreciate it if others could grep for "FIXME THREAD" and see
if some of these are harmless, or what.

This allows these citation packages can be Required by the document layout.
LyX handles the package ordering, loading any of these packages before natbib
when both are required by the document layout. For example, apacite can be
used with or without natbib.
The package achicago isn't compatible with natbib out-of-the-box,
but the following compatibility code makes it work:
\usepackage{achicago}
\let\achicagobib\thebibliography
\usepackage[authoryear]{natbib}
\let\thebibliography\achicagobib
\let\UnexpandableProtect\protect
\let\SCcite\astroncite
Filenames embraced in <...> can occur anywhere on the line and multiple times. This fixes for me the case that graphics included via ERT were not tracked. It probably also fixes#8336.

variable. This is done in the preferences, much like as the PATH prefix.
A single '.' in the paths will get replaced with the current document dir
and also non-absolute paths will be prefixed with that dir.
The default semantics of TEXINPUTS apply, such that, for example, if a
path is terminated with a double slash, all subdirectories will be also
searched by both the TeX engine and ancillary programs such as dvi
previewers or dvips. As an example, if the prefix is set to ".:figs", the
TEXINPUTS variable will be set as ".:<docdir>:<docdir>/figs:$ORIGTEXINPUTS",
where <docdir> is the document directory.
The initial '.' is necessary to address the actual current dir (this will
be the temp dir at preview time), while if TEXINPUTS was initially unset,
such that $ORIGTEXINPUTS is empty, a colon (or semicolon on Windows) will
end the path list. This is very important, because we don't want to replace
the system directories but to complement them and, in order to do that, an
empty element has to be present in the list. Indeed, according to the
TEXINPUTS semantics, an empty element means the standard search path.
This works whether TEXINPUTS is originally set or not, because if the
original TEXINPUTS starts with a colon (meaning that the standard search
path is wanted there) we will have an empty element at that point,
otherwise the final colon will simply serve as a path separator.
Of course, on Windows a ';' has to be used as a path separator. LyX will
take care of transforming the platform path list into one understandable
by the TeX engine. For example, this will be the case for a Cygwin version
of LyX using a native Windows TeX engine or viceversa. I tested all of
this and it works for me.
