The calls to `fgets` in `src/nvim/if_cscope.c` (and elsewhere) can show
communication errors to the user if a signal is delivered during its
system calls. For plugins that proxy subprocess output into cscope
requests, a `SIGCHLD` might *always* interfere with calls into `fgets`.
To see this in a debugger, put a breakpoint on `cs_reading_emsg` and
watch signals come in (with lldb, using `process handle --notify true
--pass true`). Next, run a subcommand from neovim that calls through
cscope when it returns. A tag picker plugin, like vim-picker and fzy,
with `cscopetag` and `cscopetagorder=0` set, reproduced this reliably.
The breakpoint will hit after a `SIGCHLD` is delivered, and `errno` will
be set to 4, `EINTR`.
The caller of `fgets` should retry when `NULL` is returned with `errno`
set to `EINTR`.
Fix quickfix performance optimization which prevented quickfix items
from being updated when there were multiple windows with location lists
but the buffer with errors only in one of the lists.
vim-patch:8.0.0012
Problem: Typos in comments.
Solution: Change "its" to "it's". (Matthew Brener, closesvim/vim#1088)
9af4184276
vim-patch:8.0.0046
version.c: mark 8.0.0046 applied
vim-patch:8.0.0063
version.c: mark 8.0.0063 as NA patch
Problem: Cannot get the number of the current quickfix or location list.
Solution: Use the current list if "nr" in "what" is zero. (Yegappan
Lakshmanan) Remove debug command from test.
890680ca63
Problem: When creating a bufref, then using :bwipe and :new it might get
the same memory and bufref_valid() returns true.
Solution: Add br_fnum to check the buffer number didn't change.
45e5fd135d
Problem: The buffer that quickfix caches for performance may become
invalid. (Daniel Hahler)
Solution: Reset qf_last_bufref in qf_init_ext(). (Daniel Hahler,
closesvim/vim#1728, closesvim/vim#1676)
6dd4a53502
Problem: Get E924 when switching tabs. ()
Solution: Use win_valid_any_tab() instead of win_valid(). (Martin Vuille,
closesvim/vim#1167, closesvim/vim#1171)
0a9046fbcb
Problem: Checking did_throw after executing autocommands is wrong. (Daniel
Hahler)
Solution: Call aborting() instead, and only when autocommands were executed.
21662be221
Problem: On MS-Windows quickix does not handle a line with 1023 bytes
ending in CR-LF properly.
Solution: Don't consider CR a line break. (Ken Takata)
796aa9c804
Problem: QuickFixCmdPre and QuickFixCmdPost autocommands are not always
triggered.
Solution: Also trigger on ":expr", ":cbuffer", etc. (Yegappan Lakshmanan)
04c4ce650f
Problem: Cannot get all information about a quickfix list.
Solution: Add an optional argument to get/set loc/qf list(). (Yegappan
Lakshmanan)
d823fa910c
Problem: More buf_valid() calls can be optimized.
Solution: Use bufref_valid() instead.
NOTE: Some changes related to channels and the Python and Netbeans interfaces
were obviously left out.
7c0a2f367f
Problem: buflist_findname_stat() may find a dummy buffer.
Solution: Set the BF_DUMMY flag after loading a dummy buffer. Start
finding buffers from the end of the list.
NOTE: In Neovim, buflist_findname_stat() was replaced by
buflist_findname_file_id() in c41535d69.
ea3f2e7be4
Problem: buf_valid() can be slow when there are many buffers.
Solution: Add bufref_valid(), only go through the buffer list
when a buffer was freed.
b25f9a97e9
Problem: When there are many errors adding them to the quickfix list takes
a long time.
Solution: Add BLN_NOOPT. Don't call buf_valid() in buf_copy_options().
Remember the last file name used. When going through the buffer
list start from the end of the list. Only call buf_valid() when
autocommands were executed.
8240433f48
Problem: Compiler warning for char/char_u conversion. (Tony Mechelynck)
Inefficient code.
Solution: Use more lines to fill with spaces. (Nikolai Pavlov) Add type cast.
16ec3c9be3
Problem: When using ":vimgrep" may end up with duplicate buffers.
Solution: When adding an error list entry pass the buffer number if possible.
