FileName::tempName() created a new temp file name by using qt to create a
temporary file with a unique name, and then deleting that file and returning
the name. This was unsafe, since other processes or even other threads of the
running LyX could create files with the same name between deletion and then
using the temp name.
This is fixed by using the TempFile class instead. As a side effect, a few
cases where the temp files were not deleted after usage were fixed as well.
The only place that is still unsafe is createTmpDir().
the minibuffer. As the comments explain, this leaves a different
bug, but (a) it isn't a crash and (b) it probably won't affect
many users, if *any* users.
In [19024f72\lyxgit] this line was removed. Later this caused that floats were converted to strings using ','s instead of '.'s. Readding this line fixes this.
Get the default language by a mix of QLocale and LyXRC::gui_language
Known limitations:
* encoding is supposed to be UTF-8 (the charset parameter is checked);
* context is not handled (implemented differently in LyX);
* plural forms not implemented (not used for now in LyX);.
* tThe byte endianness of the machine on which the .mo file have been
built is expected to be the same as the one of the machine where this
code is run.
LyX uses QTemporaryFile to create a unique temporary directory. This
temporary directory will consist of two random characters and the process
identifier (PID).
Currently, the two random characters are often the same because Qt's
random generator was not seeded. If there are a lot of lyx temporary
directories accumulated, the chance of failing to find a unique temporary
directory is (N/100)%.
The temporary directories can be left behind if either LyX crashes, or
when a file in the temporary directory is opened in another viewer when
LyX closes. This can be a pdf that is viewed in a reader that disallows
the file to be removed while viewing it.

There are several places I was not sure what to do. These are marked
by comments beginning "LASSERT:" so they can be found easily. At the

Most images are generated by development/tools/generate_symbols_images.py, but
some were drawn manually. Now there is no image missing from the ones the
script can generate.
These are all generated by development/tools/generate_symbols_images.py, the
only manual adjustments were renamings due to case sensitive file systems on
windows.
buffer-forall only takes one parameter now, which is the LFUN to
dispatch on all non-hidden buffers. A hidden buffer is defined as being
internally open in LyX, but not visible in any window (view).
Thanks, JMarc.
In order to interact with native osx applications, AppleScript support is a plus.
Here is a patch that makes LyX respond to a simple command (run) and that allows to communicate with LyX as with the LyX client.
Example of use:
tell application "LyX" to run "server-get-filename" with argument ""'
returns
message:/Users/bpiwowar/newfile1.lyx, code:0
with a message and the error code
The goal here is to get rid of the old code that modified variables
LANGUAGE and LC_ALL, therefore creating the problems mentionned
in the ticket.
In the new system, there is no explicit "GUI" message handler, that
needs to be reset at each language change. Instead, getGuiMessages
calls getMessages with the correct parameter. This allows to simplify
greatly the code and to remove a lot of old cruft.
The idea is to record undo at the place where the document is modified:
1/ in Buffer::updateBuffer, add a recordUndo, with the caveat that a
const_cast has to be used (because updateBuffer is const but
modifies the document, go figure).
2/ in GuiApplication::dispatch, add an extra undo group that
encompasses the updateBuffer call. Some other undo groups may be
redundant now, but it is not a problem since they do not cost
anything.
In this version, the idea is to record undo at the place where the document is modified, which is definitely cleaner.

Both bugs above were due to a missing screen update. This patch
updates the current view after dispatching a lyxserver command
and thus solves both.
The patch is quite strightforward and the only difficulty was due
to the fact that the lyxserver needs the result of the dispatched
command. Now, GuiApplication::dispatch(FuncRequest const &) does
right this, but does not return the result, while
GuiApplication::dispatch(FuncRequest const &, DispatchResult &)
is called by the former but does not return the result. So, I
split the first one, isolating the code performing the update,
such that the second one can also update the current view when
the caller is the lyx server. When the action is initiated by
anything different from the lyx server, the behavior is unchanged.
Of course this will only work if output_changes was true when creating the
.tex file.

mess. It didn't work, so we have to do that.
