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.
* Fix memory leaks.
* Add comments about initializations and checking for successful results.
* Add checks for NULL deref.
* Consistency in "TODO" vs "TO-DO" comments!
Modified by mchinen to cleanup debug messages and fix unbalanced mutex on error.
Original patch notes:
OD loader doesn't properly continue scanning files
BUG:
* import large audio file with OD import
* save and close project before OD finishes
* open project again: OD failes badly on continuing
Syntoms:
* .auf.auf.auf worm files ...
* truncated wave display
The isse is subtile:
<odpcmaliasblockfile summaryfile="e000031a.auf" aliasfile="/home/chris/Records/test/0.5seek+cue.flac" aliasstart="26738688" aliaslen="524288" aliaschannel="1"/>
A ODPCMAliasBlockFile is a AliasBlockFile which has 3 overloaded
constructer. One of then silently adds '.aup' to the summaryfile.
So when creating those tracks from XML, we must use the other constructor.
Now we run into a second bug:
AudacityProject::OpenFile calls ProjectFSCK after reading which deletes
the just created empty directories in the _data/e00 dir. OD is doomed.
So simply skip rmdir in fsck. The OD..Blockfiles will disapper when the
OD finishes, so empty dirs will be deleted on further opening the project.
I refactored the code into AudacityApp with a new timer. This is provisional pending discussion - if it is decided that it should go somewhere else I will move it.
Make DirManager::MoveToNewProjectDirectory(), DirManager::CopyToNewProjectDirectory(), and several BuildFromXML() methods check the result of AssignFile() and do something appropriate about it on failure, rather than ignoring it. Also made AssignFile() check whether the assigned name is well-formed, so it doesn't always return TRUE when disckcheck is FALSE.
Briefer and more correct checks for uninitialized wxFileName objects.
Several "//ANSWER-ME" comments about file ops and commented-out cruft to probably remove.
Clarify some logic and readability.
better handling of error conditions in all BuildFromXML methods, per comment:
// BuildFromXML methods should always return a BlockFile, not NULL,
// even if the result is flawed (e.g., refers to nonexistent file),
// as testing will be done in DirManager::ProjectFSCK().
better handling of error conditions in PCMAliasBlockFile::BuildFromXML so that DirManager::ProjectFSCK can report cases of missing PCMAliasBlockFile files on opening projects where missing files were not corrected
code cleanup
naming improvements for clarity (e.g., aliasedFileName instead of aliasedFile for an instance of wxFileName -- it's not an instance of AliasedFile)
parens, not square brackets, for parenthetic phrases
Basic problem was in using wxConvUTF8 instead of wxConvFile. I believe wxConvFile should work on all platforms, but if not we can "#ifdef _WIN32" its use.
Also simplified the code by getting rid of the mFileNameChar member. It was used only in ODPCMAliasBlockFile::WriteSummary() so there's no reason to do the conversion from mFileName in so many places -- just do it once, in ODPCMAliasBlockFile::WriteSummary().
Also some minor refactoring.
This feature works with mp3 right now - may work on other formats, but that will be a seperate commit.
It is not enabled so most of the changes won't even be compiled, and those that do won't be run.
To enable it uncommment the EXPERIMENTAL_ODFFMPEG def in Experimental.h
