Problem: Getting name of cleared highlight group is wrong. (Matt Wozniski)
Solution: Only skip over cleared names for completion. (closes#1592)
Also fix that a cleared group causes duplicate completions.
Problem: Not enough testing for the client-server feature.
Solution: Add more tests. Add the remote_startserver() function. Fix that
a locally evaluated expression uses function-local variables.
Problem: The return value of mode() does not indicate that completion is
active in Replace and Insert mode. (Zhen-Huan (Kenny) Hu)
Solution: Add "c" or "x" for two kinds of completion. (Yegappan Lakshmanan,
closes#1397) Test some more modes.
Problem: It is not so easy to write a script that works with both Python 2
and Python 3, even when the Python code works with both.
Solution: Add 'pyxversion', :pyx, etc. (Marc Weber, Ken Takata)
Problem: When making a character lower case with tolower() changes the byte
cound, it is not made lower case.
Solution: Add strlow_save(). (Dominique Pelle, closes#1406)
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: Warning for an unused parameter when the libcall feature is
disabled. Warning for a function type cast when compiling with
-pedantic.
Solution: Add UNUSED. Use a different type cast. (Damien Molinier)
Problem: When compiling with EBCDIC defined the build fails. (Yaroslav
Kuzmin)
Solution: Move sortFunctions() to the right file. Avoid warning for
redefining __SUSV3.
Problem: str2nr() and str2float() do not always work with negative values.
Solution: Be more flexible about handling signs. (LemonBoy, closes#1332)
Add more tests.
Problem: JSON with a duplicate key gives an internal error. (Lcd)
Solution: Give a normal error. Avoid an error when parsing JSON from a
remote client fails.
Problem: To pass buffer content to system() and systemlist() one has to
first create a string or list.
Solution: Allow passing a buffer number. (LemonBoy, closes#1240)
Problem: When reading channel output in a timer, messages may go missing.
(Skywind)
Solution: Add the "drop" option. Write error messages in the channel log.
Don't have ch_canread() check for the channel being open.
Problem: When using ch_read() with zero timeout, can't tell the difference
between reading an empty line and nothing available.
Solution: Add ch_canread().
Problem: When the input or output is not a tty Vim appears to hang.
Solution: Add the --ttyfail argument. Also add the "ttyin" and "ttyout"
features to be able to check in Vim script.
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: Order of matches for 'omnifunc' is messed up. (Danny Su)
Solution: Do not set compl_curr_match when called from complete_check().
(closes#1168)
Problem: Code for MS-Windows is complicated because of the exceptions for
old systems.
Solution: Drop support for MS-Windows older than Windows XP. (Ken Takata)
Problem: Can't tell which part of a channel has "buffered" status.
Solution: Add an optional argument to ch_status(). Let ch_info() also
return "buffered" for out_status and err_status.
Problem: A string argument for function() that is not a function name
results in an error message with NULL. (Christian Brabandt)
Solution: Use the argument for the error message.
Problem: Crash when stop_timer() is called in a callback of a callback.
Vim hangs when the timer callback uses too much time.
Solution: Set tr_id to -1 when a timer is to be deleted. Don't keep calling
callbacks forever. (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().
