... And in some places where a library uses signed types, assert that
the reported number is not negative.
What led me to this, is that there are many places where a size_t value for
an allocation is the product of a number of channels and some other number.
...They may never have been large enough to matter, but some seek offsets into
files were written as 64 bits but read back as only 32. It ought to be
consistent.
... for functions in final classes.
override is like const -- it's not necessary, but it helps the compiler to
catch mistakes.
There may be some overriding functions not explicitly declared virtual and I did
not identify such cases, in which I might also add override.
... Should have no effect on generated code, except perhaps some slight faster
virtual function calls. Mostly useful as documentation of design intent.
Tried to mark every one of our classes that inherits from another, or is a
base for others, or has abstract virtual functions, and a few others besides.
A 4hr track used to take about 20s to cut a few samples. This is now significantly improved, to around 3s. Leland did this by
(a) moving the size calculation to when we examine the undo history, so it isn't slowing down the edits.
(b) in size calculation, using sizes that are cached rather than going to disk to find the sizes.
(c) writing the autosave file which is to an FFIle to a string first, i.e. using XMLStringWriter as a buffer for XMLFileWriter.
Step (c) may also make autosave marginally safer, as the risk of a partially updated autosave file is reduced.
Correct string formatting for:
2/15 %d + enum => %d + int
3/15 %lld + int64_t => %lld + long long
4/15 %d + int64_t => %lld + long long
5/15 %d + double => %f + double
6/15 %d + int32_t => %d + int
7/15 %d + intptr_t => %p + void*
8/15 gint, guint
9/15 %d + long => %ld + long
10/15 %n + int => %d + int
11/15 %x + int => %x + unsigned int
12/15 %f + int => %d + int
13/15 %S + wxChar* => %s + wxChar*
14/15 %d + size_t => %d + int
15/15 %d + size_t => %lld + long long
"The functions wxString::Format, wxString::Printf (and others indirectly) have become stricter about parameter types that don't match (format specifier vs. function parameters). So the bugs (that were already present in audacity before) become visible in wx3.0 as error message dialogs. I've checked all occurrences of Printf, wxPrintf, PrintfV, Format, FormatV, wxLogDebug and wxLogError systematically and made the type match."
Note (9/15): In TrackPanel.cpp, ExportMP2.cpp and CompareAudioCommand.cpp this patch supersedes related change done in r13466 because the new solution requires fewer casts and therefore simplifies the code.
Note: Many .po files are affected, and we need to be very careful about this. Incorrect "%d" and similar in translation files may lead to crashes in those languages (only). This is something we should actually have been more careful about in the past. We need to write a script to check that the "%d" and similar format specifiers match between English and translation.
