Problem: Using a full path is supported for 'directory' but not for
'backupdir'. (Mikolaj Machowski)
Solution: Support 'backupdir' as well. (Christian Brabandt, closes#179)
Problem: Swap file warning for a file in a non-existing directory, if there
is another with the same file name. (Juergen Weigert)
Solution: When expanding the file name fails compare the file names.
Problem: FEAT_WINDOWS adds a lot of #ifdefs while it is nearly always
enabled and only adds 7% to the binary size of the tiny build.
Solution: Graduate FEAT_WINDOWS.
Problem: When opening a buffer on a directory and inside a try/catch then
the BufEnter event is not triggered.
Solution: Return NOTDONE from readfile() for a directory and deal with the
three possible return values. (Justin M. Keyes, closes#1375,
closes#1353)
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: 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: Gcc sanitizer complains about using a NULL pointer to memmove().
Solution: Only call memmove when there is something to move. (Vittorio
Zecca)
Problem: On some systems automatically adding the missing EOL causes
problems. Setting 'binary' has too many side effects.
Solution: Add the 'fixeol' option, default on. (Pavel Samarkin)
Problem: When setting the crypt key and using a swap file, text may be
encrypted twice or unencrypted text remains in the swap file.
(Issue 369)
Solution: Call ml_preserve() before re-encrypting. Set correct index for
next pointer block.
Problem: When starting several Vim instances in diff mode, the temp files
used may not be unique. (Issue 353)
Solution: Add an argument to vim_tempname() to keep the file.
Problem: Valgrind reports errors when running test 72. (Dominique Pelle)
Solution: Reset the local 'cryptmethod' option before storing the seed.
Set the seed in the memfile even when there is no block0 yet.
Problem: Encryption implementation is messy. Blowfish encryption has a
weakness.
Solution: Refactor the encryption, store the state in an allocated struct
instead of using a save/restore mechanism. Introduce the
"blowfish2" method, which does not have the weakness and encrypts
the whole undo file. (largely by David Leadbeater)
Problem: MS-Windows: When there is a colon in the file name (sub-stream
feature) the swap file name is wrong.
Solution: Change the colon to "%". (Yasuhiro Matsumoto)
Problem: When running out of memory during startup trying to open a
swapfile will loop forever.
Solution: Let findswapname() set dirp to NULL if out of memory.
Problem: When recovering a file a range of lines is missing. (Charles Jie)
Solution: Reset the index when advancing to the next pointer block. Add a
test to verify recovery works.
Problem: When using ":make", typing the next command and then getting the
"reload" prompt the next command is (partly) eaten by the reload
prompt.
Solution: Accept ':' as a special character at the reload prompt to accept
the default choice and execute the command.
