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.
If LyX thinks the export was successful but no output file was
produced for preview, then something is wrong (most likely LyX
did not detect an error that occurred during export).
Also clean up some logic.
One declaration of doExport() was not used, and the other one was only used by
Buffer, so make it private since returning the exported file name is a bit
strange if it can also appear as input argument.
Add display_pixel_ratio to buffer params to use it for displays with high resolution.
It holds the highest ratio between physical pixels and device-independent pixels of the LyX application.
Preview snippets will be generated using this value to get high resolution preview.
As discussed on the list. No automatic contents detection is done, the user
needs to use the special paste menu instead. I used the new TempFile class
for safe temporary file handling.
The documentation would go into section 2.2 of UserGuide.lyx, but I am not
allowed to edit that document.
Both cvs and svn are able to retrieve non-existing files from repository,
but this was only implemented for rcs. This is a prerequisite for the
planned move and copy VCV operations. I also improved error schecking and
used extractFromVC() also for files specified on the command line if they
do not exist (in GUI mode, it was already the case in non-GUI mode).
The code does a reload on the buffer to avoid loose pointers if the
file changes directory. This commit adds a bool parameter to
Buffer::reload to allow for keeping the undo stack intact. This is of
couse only wanted in this case, not when reloading an earlier version
of the file.
We split Buffer::clone() into various routines that know whether
to clone the children.

The global list of cloned buffers was a bad idea. We don't have multiple
export threads, but we can have multiple autosave threads. So now we keep
more than one of these lists at the same time, and each cloned buffer has
a pointer to the relevant list. Note that this would make multiple export
possible, if we wanted to do that at some time.

- Let all doExport calls honor maintain_unincluded_children
- Also don't let the behaviour depend on supplying the result_file parameter

All calls to doExport from outside of Buffer have the same algorithm to
determine whether the included children parameter should be true. Moreover,
this decision is only based on information from the Buffer itself.
Now, Buffer only has 1 public function doExport and preview.

This restores \input@path handling, which turns out to be necessary, as
the TEXINPUTS mechanism is not used with relative paths. It turns out
that both methods must be used, because \input@path does not work in all
cases (most notably with tikz).

The PreviewLoader is created directly by Buffer on demand. The PreviewLoader cache was complex and unneeded because there is one and only one PreviewLoader per Buffer.

It's amazing we haven't seen problems with this before. The basic problem is that buf.errorList("whatever") would always return the same global, static error list, if it did not already exist. So, to a significant extent, there was only one global error list!
