Problem: When using an assert function one can either specify a message or
get a message about what failed, not both.
Solution: Concatenate the error with the message.
Problem: Ubsan reports errors for integer overflow.
Solution: Define macros for minimum and maximum values. Select an
expression based on the value. (Mike Williams)
Problem: When compiling with EBCDIC defined the build fails. (Yaroslav
Kuzmin)
Solution: Move sortFunctions() to the right file. Avoid warning for
redefining __SUSV3.
Problem: On MS-Windows some float functions return a different value when
passed unusual values. strtod() doesn't work for "inf" and "nan".
Solution: Accept both results. Fix str2float() for MS-Windows. Also
reorder assert function arguments.
Problem: When the channel callback gets job info the job may already have
been deleted. (lifepillar)
Solution: Do not delete the job when the channel is still useful. (ichizok,
closes#1242, closes#1245)
Problem: Cannot make Vim fail on an internal error.
Solution: Add IEMSG() and IEMSG2(). (Domenique Pelle) Avoid reporting an
internal error without mentioning where.
Problem: A channel is closed when reading on stderr or stdout fails, but
there may still be something to read on another part.
Solution: Turn ch_to_be_closed into a bitfield. (Ozaki Kiichi)
Problem: getwininfo() and getbufinfo() are inefficient.
Solution: Do not make a copy of all window/buffer-local options. Make it
possible to get them with gettabwinvar() or getbufvar().
Problem: Cannot map <M-">. (Stephen Riehm)
Solution: Solve the memory access problem in another way. (Dominique Pelle)
Allow for using <M-\"> in a string.
Problem: A funccal is garbage collected while it can still be used.
Solution: Set copyID in all referenced functions. Do not list lambda
functions with ":function".
Problem: Using function() with a name will find another function when it is
redefined.
Solution: Add funcref(). Refer to lambda using a partial. Fix several
reference counting issues.
Problem: User defined functions can't be a closure.
Solution: Add the "closure" argument. Allow using :unlet on a bound
variable. (Yasuhiro Matsumoto, Ken Takata)
Problem: Using submatch() in a lambda passed to substitute() is verbose.
Solution: Use a static list and pass it as an optional argument to the
function. Fix memory leak.
Problem: filter() and map() either require a string or defining a function.
Solution: Support lambda, a short way to define a function that evaluates an
expression. (Yasuhiro Matsumoto, Ken Takata)
Problem: When a file gets a name when writing it 'acd' is not effective.
(Dan Church)
Solution: Invoke DO_AUTOCHDIR after writing the file. (Allen Haim, closes
#777, closes#803) Add test_autochdir() to enable 'acd' before
"starting" is reset.
