arbitrary length computed sound. (So as before, sound after the selection
is shifted in time if the replacement sound is shorter or longer than the
original selection.) If stereo is computed and one channel is shorter than
the other, the shorter channel is extended with zeros to match the length
of the longer one.
This update contains to important features:
1. Improved performance of WAL mode locking primitives in cases where there are hundreds of connections all accessing the same database file at once
2. In WAL mode, if a writer crashes and leaves the shm file in an inconsistent state, subsequent transactions are now able to recover the shm file even if there are active read transactions. Before this enhancement, shm file recovery that scenario would result in an SQLITE_PROTOCOL error.
On second display of LV2 effect using an X11UI, Audacity
would hang due to the glib class not being in the expected
state.
Workaround is to not unload the suil wrapper library. The
unload was already being bypassed on Windows so I'm unsure
why the author didn't do it on the other platforms.
The real problem is that whatever created the file mentioned in
the bug report, did not include the Unicode BOM and libid3tag
defaulted to big endian. This commit uses some code from ReactOS
that TRIES to autodetect the endianness.
When compiling, I got this error:
/lib-src/libnyquist/nyquist/nyqsrc/sndread.c: In function 'snd_make_read':
/lib-src/libnyquist/nyquist/nyqsrc/sndread.c:169:30: error: invalid operands to binary | (have 'int' and 'long int *')
169 | susp->sf_info.format |= format;
| ^~
I would like to suggest this fix for this error.
* [NYQUIST] Fix build on CYGWIN
Cygwin requires to include unistd.h for building without errors.
* [NYQUIST] Fix build on CYGWIN.

Possible fix for bug #590
This change reduces the risk of LADSPA plugins referencing
Audacity symbols by using the RTLD_DEEPBIND flag when loading
the plugins.
It also addresses an issue specific to the "blop" plugins where
they load their own libraries (without RTLD_DEEPBIND).
A much better solution would be to change Audacity's default
symbol visibility to "hidden" which would expose ONLY symbols
specificially marked as visible.

Bug1223: (correction). Fix new potential crash in following pointer.
With recent changes to the Nyquist code for freeing blocks, the pointer 'next' could be uninitialised when 'list' points to the zero chain. So Audacity would follow a rogue pointer. We'd get away with it if the uninitialised value happened to be zero.

Modified WIN32 32-bit XLisp to use 64-bit FIXNUMs. This allows XLisp and Nyquist to handle big sounds even on 32-bit machines. Probably at some cost, but inner loops are mostly float and int32, and the Nyquist release is 64-bit anyway. Maybe we'll have to run some benchmarks on Audacity, which is still 32-bit on Windows.

This commit has many more fixes to handle long (64-bit) sounds, including a lot of fixes for warnings by Visual Studio assigning int64_t to long (works on macOS, doesn't work on VS). This was compiled and tested on macOS, and even computed a 27.1-hour sound using OSC, LP, SUM and MULT (haven't tested I/O yet).
------------------------------------------------------------------------
r297 | rbd | 2020-10-07 13:04:02 -0500 (Wed, 07 Oct 2020) | 2 lines
This is a major cleanup. It started with the goal of changing long to int64_t for sample counts so that on 64-bit windows, where long is only 32-bits, the sample counts would nevertheless be 64-bit allowing long sounds, which was a limitation for long recordings in Audacity. Since I was using compiler warnings to track possible loss-of-precision conversions from 64-bit sample counts, and there were *many* warnings, I started cleaning up *all* the warnings and ended up with a very large set of changes, including "modernizing" C declarations that date back to XLisp and CMU MIDI Toolkit code and were never changed. This version runs all the examples.sal code on macOS, but will surely have problems on Windows and Linux given the number of changes.

That seems to be going toward a fully vectorized model. Not going there for now.
