Problem: Leaking memory when redefining a function.
Solution: Don't increment the function reference count when it's found by
name. Don't remove the wrong function from the hashtab. More
reference counting fixes.
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: 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: When updating viminfo with file marks there is no time order.
Solution: Remember the time when a buffer was last used, store marks for
the most recently used buffers.
Problem: On MS-Windows large files (> 2Gbyte) cause problems.
Solution: Use "off_T" instead of "off_t". Use "stat_T" instead of "struct
stat". Use 64 bit system functions if available. (Ken Takata)
Problem: Using 32-bit Perl with 64-bit time_t causes memory corruption.
(Christian Brabandt)
Solution: Use time_T instead of time_t for global variables. (Ken Takata)
Problem: When writing viminfo merging current history with history in
viminfo may drop recent history entries.
Solution: Add new format for viminfo lines, use it for history entries. Use
a timestamp for ordering the entries. Add test_settime().
Add the viminfo version. Does not do merging on timestamp yet.
Problem: When a channel appends to a buffer that is 'nomodifiable' there is
an error but appending is done anyway.
Solution: Add the 'modifiable' option. Refuse to write to a 'nomodifiable'
when the value is 1.
Problem: When using a partial on a dictionary it always gets bound to that
dictionary.
Solution: Make a difference between binding a function to a dictionary
explicitly or automatically.
Problem: Callbacks are invoked when it's not safe. (Andrew Stewart)
Solution: When a channel is to be closed don't invoke callbacks right away,
wait for a safe moment.
Problem: Leaking memory when there is a cycle involving a job and a
partial.
Solution: Add a copyID to job and channel. Set references in items referred
by them. Go through all jobs and channels to find unreferenced
items. Also, decrement reference counts when garbage collecting.
Problem: The versplit feature makes the code uneccessary complicated.
Solution: Remove FEAT_VERTSPLIT, always support vertical splits when
FEAT_WINDOWS is defined.
Problem: The Sniff interface is no longer useful, the tool has not been
available for may years.
Solution: Delete the Sniff interface and related code.
Problem: Error when reading fails uses wrong errno. Keeping channel open
after job stops results in test failing.
Solution: Move the error up. Add ch_job_killed.
