Problem: tagfiles() can have duplicate entries.
Solution: Simplify the filename to make checking for duplicates work better.
Add a test. (Dominique Pelle, closes#2979)
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 'hlsearch' is set and matching with the last search pattern
is very slow, Vim becomes unusable. Cannot quit search by
pressing CTRL-C.
Solution: When the search times out set a flag and don't try again. Check
for timeout and CTRL-C in NFA loop that adds states.
Problem: The ":stag" command does not respect 'switchbuf'.
Solution: Check 'switchbuf' for tag commands that may open a new window.
(Ingo Karkat, closes#1681) Define macros for the return values
of getfile().
Problem: When the same tag appears more than once, the order is
unpredictable. (Charles Campbell)
Solution: Besides using a dict for finding duplicates, use a grow array for
keeping the tags in sequence.
Problem: Coverity gets confused by the flags passed to find_tags() and
warnts for an uninitialized variable.
Solution: Disallow using cscope and help tags at the same time.
Problem: Jumping to a tag that is a static item in the current file fails.
(Kazunobu Kuriyama)
Solution: Make sure the first byte of the tag key is not NUL. (Suggested by
James McCoy, closes#1387)
Problem: Detecting duplicate tags uses a slow linear search.
Solution: Use a much faster hash table solution. (James McCoy, closes#1046)
But don't add hi_keylen, it makes hash tables 50% bigger.
Problem: When reading English help and using CTRl-] the language from
'helplang' is used.
Solution: Make help tag jumps keep the language. (Tatsuki, test by Hirohito
Higashi, closes#1249)
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: When cancelling the :ptjump prompt a preview window is opened for
a following command.
Solution: Reset g_do_tagpreview. (Hirohito Higashi) Add a test. Avoid that
the test runner gets stuck in trying to close a window.
Problem: There is no equivalent of 'smartcase' for a tag search.
Solution: Add value "followscs" and "smart" to 'tagcase'. (Christian
Brabandt, closes#712) Turn tagcase test into new style.
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: 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: ":help !!" does not find the "!!" tag in the help file. (Ben
Fritz)
Solution: When reading the start of the tags file do parse lines that are
not header lines.
Problem: Tags are not found in case-folded tags file. (Darren cole, Issue
90)
Solution: Take into account that when case folding was used for the tags
file "!rm" sorts before the "!_TAG" header lines.
