This is the result of the discussion on the list "2.1.0 Blocker". Thanks to
all contributors!
The main idea is to use thread-local storage for all static variables.
This solution does not need any mutex. For more details, see the comment in
unicode.h.
It is no longer needed, and it had a comment that it needed review...
Now anybody who tries to make a copy again is forced to think about it,
instead of trying and using possibly wrong semantics by accident.
The Messages::gui_lang_ variable is instantiated in the '#ifdef ENABLE_NLS' block. To prevent compile problems, we should also instantiate it when NLS is disabled.
Make sure that the configure script only checks features using the C++ compiler.
Also get rid of our last C files, since they are not compiled nor distributed anyway.
The path to the lyx binary is either <build_dir>/bin (CMake) or
<build_dir>/src (autotools). This means the po directory can be found one
directory up.
Since 00387b2a38a1d5 it is possible to construct a dummy Messages object
which does not translate at all. With the old gettext implementation, a
Messages object without a defined language would have used a language from
an environment variable. Therefore, the duplicate definition of _() is no
longer needed. This gettext removal was really a good idea!
This is done by handling explicitly a dummy Message object, where no parsing of mo file is attempted. This avoids in turn that the lyxerr object is used during initialization of a global dummy Message object.
With gettext, we have been forced to install .mo files at the right place in order to read them. Now that we have our code, the situation changes.
* Add new method Package::messages_file(code), when returns the right path, depending on whether we are running in place.
* In Messages class use that intead of the existing one.
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.
Now, the temporary directories are composed of the PID + 8 random
characters. This used to be the PID + 2 random characters.

When running the test, you'll get the following messages:
Testing ../../src/../lib/layouts/siamltex.layout...
Layout.cpp (268): Cannot copy unknown style `Enumerate'
Testing ../../src/../lib/layouts/svglobal.layout...
Cannot delete style `Dedication'
Testing ../../src/../lib/layouts/svjog.layout...
Cannot delete style `Dedication'
Testing ../../src/../lib/layouts/svprobth.layout...
Cannot delete style `Dedication'
These are no errors of Layout::write(), but they indicate problems in the
definition of the layout files.
Kornel, it would be nice if you could do the cmake part.
* report results in milliseconds instead of microseconds
* report total time spent in block, additionally to mean time
* cause compilation error with --enable-stdlib-debug
each failure.
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
moment, they are at:
Author.cpp:105: // LASSERT: What should we do here?
Author.cpp:121: // LASSERT: What should we do here?
Buffer.cpp:4525: // LASSERT: Is it safe to continue here, or should we just return?
Cursor.cpp:345: // LASSERT: Is it safe to continue here, or should we return?
Cursor.cpp:403: // LASSERT: Is it safe to continue here, or should we return?
Cursor.cpp:1143: // LASSERT: There have been several bugs around this code, that seem
CursorSlice.cpp:83: // LASSERT: This should only ever be called from an InsetMath.
CursorSlice.cpp:92: // LASSERT: This should only ever be called from an InsetMath.
LayoutFile.cpp:303: // LASSERT: Why would this fail?
Text.cpp:995: // LASSERT: Is it safe to continue here?
When using CMake, the binary files are stored in <build-dir>/bin. LyX can't fin tex2lyx with the current code. So, we have to point configure.py to explicitly look in the binary dir.
FileName::tempName() is not thread safe, since the QTemporaryFile object is
immediately deleted after creating it. Therefore, another thread could create
the same temporary file in the time span before the user of FileName::tempName()
recreates it. This is not as theoretical as it may look: I observed that
repeated creation and deletion of QTemporaryFile objects always use the same
name.
This problem is solved by the new class TempFile which should be used like
QTemporaryFile itself.
This will be needed for layout forward compatibility, and could also be used
for a layout editor. Writing was only implemented for styles, not for complete
layout files (text class). I rarely made use of default values for missing
variables which exist in read(), so the output it a bit verbose (but more safe
against future changes). Also, some things like CopyStyle are never written for
obvious reasons.
The use of this profiler is trivial:
* #include <support/pmprof.h>
* in the block one wants to profile, add
PROFILE_THIS_BLOCK(some_identifier)
* At the end of the execution, statistics will be sent to standard error.
so we can write a limited amount when using this for TOC and
tooltip output.
This should solve the problem with slowness that Kornel noticed,
which was caused by our trying to write an entire plaintext
bibliography every time we updated the TOC. We did that because
he had a bibliography inside a branch, and we use plaintext for
creating the tooltip that goes with the branch list.
Other related bugs were fixed along the way. E.g., it turns out
that, if someone had an InsetInclude inside a branch, then we would
have been writing a *plaintext file* for that inset every time we
updated the TOC. I wonder if some of the other reports of slowness
we have received might be due to this kind of issue?
