The problem was that, if we killed export when some graphic was
being converted, or some external template was being handled, it
would only cancel that process, and then it would just continue.
To deal with that, we need to do a few things:
1. Modify the return values for some of the Converters routines,
and similarly the routines for external templates, so we can
tell when something has been canceled.
2. Throw an exception from InsetGraphics or InsetExternal when this
has happened during export, but ONLY when the Buffer is a clone.
We shouldn't be able to 'cancel' export when we're, say, generating
code for the preview pane, but this keeps us on the safe side..
The exception then has to be caught, obviously, back in the export
routines in Buffer.
Probably Coverity will be unhappy about something here, but I'll
deal with that problem as it arises.
This is mandatory for some features (such as bookmarks,pdfusetitle)
to work, and only a handful of drivers can be auto-detected by hyperref.
Fixes: #6418
Allow a LaTeX backend to run external commands after user confirmation.
This is a per document and per machine setting. The authorization has
to be given through the document settings pane, but is not recorded in
the document itself. Moving the document to either another computer or
another directory on the same computer revokes the authorization.
This can also be done by right clicking the red icon that appears in
the status bar when a document is marked as one requiring shell escape.
The patch also checks whether the user has added the -shell-escape
option to a LaTeX converter and nags the user to remove the option
(which would be used for all documents) in favor of the (per document)
support offered by LyX.
Addressing #10481.
This patch adds the new 'needauth' option for converters launching
external programs that are capable of running arbitrary code on behalf
of the user. These converters won't be run unless the user gives explicit
authorization, which is asked on-demand when the converter is about to
be run (question is not asked if the file is cached and calling the
converter is not needed).
The user prompt has a 3rd button so that he/she's not prompted again
for (any converter over) the same document (identified through
buffer->absFileName()).
Two preference options are added:
lyxrc.use_converter_needauth_forbidden disables any converter with
the 'needauth' option, which is meant to force user to an explicit
action via the preferences pane, before being able to use advanced
converters that can potentially bring security threats;
lyxrc.use_converter_needauth enables prompting the user for 'needauth'
converters, or bypasses the check if not enabled, falling back to the
previous behavior.
So, the first option is for maximum security, the second is for
maximum usability.
If a converter specifies the needaux flag, latex (or xelatex) is
always run to produce the needed auxiliary files. This is wrong
because there are documents that can only be compiled with a specific
backend and thus the conversion may fail. On the other hand, even if
the document specifies the backend to be used, LyX ignores this info.
This commit rectifies this behavior by letting LyX run the same flavor
of the latex backend that shall be used for previewing the document
also for producing the auxiliary files.
to be a set. Not that speed will really be an issue here, but....
