Using a static variable here was premature optimization: fileNames() is only
called from GuiRef (directly or indirectly), and since this is a dialog the
copying of a FileNameList is not noticeable at all.
In this case I use a mutex, so the zip status of files is shared between
threads. This is possible because a deadlock can't happen, and it should give
better performance.
Don't create an intermediate copy (found by Jean-Marc).
I doubt that this has anything to do with the mystery crash, but it works, and
following the standard patterns is better anyway.
Without this, you get crashes in a few second when you set the autosave
interval to one second and edit quickly (typing new words etc). The reason
is that the cloned buffer wants to insert words into the word list and
remove them again, but it lives in a different thread.
The lyx2lyx conversion for format 352 was incomplete: It should have been
added the \use_indices setting, but it relied on the fact that the default in
LyX for missing \use_indices is the same as the old format without that
setting used. However, the default might change in the future, and later
lyx2lyx conversions rely on that setting as well.
The compiler-generated copy-constructor and assigment operators would be wrong
for IconvProcessor::Impl, since cd would be copied, and iconv_close() could
thus be called twice on the same descriptor. The old code did work, but now
IconvProcessor::Impl cannot be copied by accident in the future.
The IconvProcessor assignment operator did not delete pimpl_ and used a
non-standard signature. If you want to know why the standard signature is
important, read "Effective C++" by Scott Meyers.
The statement
if (pos < from + lyxrc.completion_minlength)
triggers a signed vs. unsigned warning. I don't know why this happens, it
could be a MSVC bug, or related to LLP64 (windows) vs. LP64 (unix)
programming model, or the C++ standard might be ambigous in the section
defining the "usual arithmetic conversions". However, using a temporary
variable is safe and works on all compilers.
* fix handling of boundary situations in Row::Elements::x2pos;
* fix handling of boundary situations in TextMetrics::getColumnNearX;
* make sure to always use Font::isVisibleRightToLeft instead of Font::isRightToLeft;
* Improve debug messages.
The horizontal position of the inset was not taken in account.
The rounding is not always the same as with the old code, but this
is not really important.
Additional changes:
* improve debug output of rows
* remove Bidi& argument of the RowPainter constructor, since it is always
an empty Bifi that is passed. This means that the Bidi class is not
used at all any more in TextMetrics.cpp. The only remaining user is
RowPainter.
Break words longer than the screen width. The code is more complicated
than I would like, but I have no better idea right now.
Implement properly the notion of a row broken by a display inset. This is useful in different places.
Also fix a bug with last line of a paragraph spotted by Kornel.
Use proper font everywhere for end-of-par marker
Fix getColumnNearX for RTL text and for centered/right-justified paragraphs.
Let computeRowMetrics update the row width.
* convert cursorX to new scheme; old computation is still there for the sake of comparison.
* use Row to compute separator width in computeRowMetrics; again, the old code is retained for now.
* Get rid of rowWidth()
* Row now contains a vector of Elements
* replace Row::dump by a proper << operator
* the width is updated as elements are added
* breakRow is reimplmented to use this infrastructure
Collect properly all strings to compute string metrics
Some changes with respect to existing code
- end of paragraph font is now the one of the text
- words longer than a line are not broken anymore. I think this is not useful if we have horizontal scrollbar
Other than that, the code is still compatible with rowWidth and friends.
