Performance of high-resolution time (clock_gettime via uv_hrtime) is
expensive on some systems. For profiling VimL, syntax, etc., we don't
care about nanosecond-precision and monotonicity edge-cases, so avoid
uv_hrtime().
closes#10328
From the uv__hrtime() source:
0cdb4a5b4b/src/unix/linux-core.c (L442-L462)
/* Prefer CLOCK_MONOTONIC_COARSE if available but only when it has
* millisecond granularity or better. CLOCK_MONOTONIC_COARSE is
* serviced entirely from the vDSO, whereas CLOCK_MONOTONIC may
* decide to make a costly system call.
*/
This micro-benchmark (Debug build) shows negligible differences on my
system:
#include <sys/time.h>
...
proftime_T tm = profile_start();
int trials = 999999;
int64_t t = 0;
struct timeval tv;
for (int i = 0; i < trials; i++) {
t += gettimeofday(&tv,NULL);
}
tm = profile_end(tm);
ILOG("%d trials of gettimeofday: %s", trials, profile_msg(tm));
tm = profile_start();
for (int i = 0; i < trials; i++) {
t += os_hrtime();
}
tm = profile_end(tm);
ILOG("%d trials of os_hrtime: %s", trials, profile_msg(tm));
tm = profile_start();
for (int i = 0; i < trials; i++) {
t += os_utime();
}
tm = profile_end(tm);
ILOG("%d trials of os_utime: %s", trials, profile_msg(tm));
ILOG("%zu", t);
Problem: Cannot use a lambda for the skip argument to searchpair().
Solution: Evaluate a partial, funcref and lambda. (LemonBoy, closesvim/vim#1454,

Problem: setline() does not work on startup. (Manuel Ortega)
Solution: Do not check for ml_mfp to be set for the current buffer.
(Christian Brabandt)

Problem: Cannot change a line in a buffer other than the current one.
Solution: Add setbufline(). (Yasuhiro Matsumoto, Ozaki Kiichi, closesvim/vim#1953)

- In appimage, the message catalog is not used because there is no
message catalog in LOCALE_INSTALL_DIR. Therefore, change to
exepath/../share/locale instead of LOCALE_INSTALL_DIR.
- The old vim style($runtime/lang) is no longer used. Thus all relevant
code is removed.
Problem: When skipping over code after an exception was thrown expression
evaluation is aborted after a function call. (Ingo Karkat)
Solution: Do not fail if not executing the expression. (closesvim/vim#4507)

Problem: ":profdel func" does not work if func was called already.
(Dominique Pelle)
Solution: Reset uf_profiling and add a flag to indicate initialization was
done.

Problem: reg_executing() is reset by calling input().
Solution: Implement a more generic way to save and restore reg_executing.
(Ozaki Kiichi, closesvim/vim#4192)
9a2c091a74
Problem: A getchar() call while executing a register resets the
reg_executing() result.
Solution: Save and restore reg_executing. (closesvim/vim#406f0fab3046c
Problem: Cannot tell whether a register is being used for executing or
recording.
Solution: Add reg_executing() and reg_recording(). (Hirohito Higashi,
closesvim/vim#2745) Rename the global variables for consistency. Store
the register name in reg_executing.

Problem: There is no function for the ":sign jump" command.
Solution: Add the sign_jump() function. (Yegappan Lakshmanan, closesvim/vim#3780)
6b7b7190aa
Problem: ":sign place" only uses the current buffer.
Solution: List signs for all buffers when there is no buffer argument.
Fix error message for invalid buffer name in sign_place().
(Yegappan Lakshmanan, closesvim/vim#3774)
b589f95b38
Problem: Functionality for signs is spread out over several files.
Solution: Move most of the sign functionality into sign.c. (Yegappan
Lakshmanan, closesvim/vim#3751)

Problem: Deleting signs and completion for :sign is insufficient.
Solution: Add deleting signs in a specified or any group from the current
cursor location. Add group and priority to sign command
completion. Add tests for different sign unplace commands. Update
help text. Add tests for sign jump with group. Update help for
sign jump. (Yegappan Lakshmanan, closesvim/vim#3731)
7d83bf4f2b
Problem: Placing signs can be complicated.
Solution: Add functions for defining and placing signs. Introduce a group
name to avoid different plugins using the same signs. (Yegappan
Lakshmanan, closesvim/vim#3652)
