* src/sysdep.c (get_host_uptime) [GNU_LINUX || CYGWIN || __ANDROID__]:
New function, replacing get_host_boot_time.
Use CLOCK_BOOTTIME instead of inspecting /proc/stat.
All callers changed. This should be an even better way to fix Bug#63496.
With a Linux kernel, use /proc/stat rather than get_boot_time
to get boot time, since when Emacs is running in a container
we want the underlying host boot time, not the container boot time.
This should be a better way to fix Bug#63496.
* src/sysdep.c: Do not include boot-time.h.
(get_host_boot_time) [GNU_LINUX || CYGWIN || __ANDROID__]:
New function.
(system_process_attributes) [GNU_LINUX || CYGWIN || __ANDROID__]:
Use it instead of get_boot_time.
* src/xdisp.c (try_scrolling): Don't loop when the
partially-visible cursor line is at the top of the window. This
looping are pointless, and just makes redisplay slow for no reason.
(Bug#78766)
I noticed this issue while looking into Bug#63496.
GNU Emacs does not infer the boot time consistently on GNU/Linux
and similar platforms: android_notifications_notify_1 and
get_boot_sec use Gnulib’s boot-time module, but process-attributes
has idiosyncratic code that evidently predates that module.
The idiosyncratic code returns an unstable etime, which is a minor bug.
Simplify process-attributes by just using Gnulib.
This returns a stable etime.
It may also fix Bug#63496; if not, we can fix Gnulib later.
* src/sysdep.c: Include <boot-time.h>.
(get_up_time) [GNU_LINUX || CYGWIN || __ANDROID__]: Remove.
(system_process_attributes) [GNU_LINUX || CYGWIN || __ANDROID__]:
Use get_boot_time instead of get_up_time.

When there are many directories on load-path, the part of load which

front to only contain directories which are likely to contain the

Add line-column tracking for tree-sitter parsers. Copied from
comments in treesit.c:
Technically we had to send tree-sitter the line and column
position of each edit. But in practice we just send it dummy
values, because tree-sitter doesn't use it for parsing and
mostly just carries the line and column positions around and
return it when e.g. reporting node positions[1]. This has
been working fine until we encountered grammars that actually
utilizes the line and column information for
parsing (Haskell)[2].
[1] https://github.com/tree-sitter/tree-sitter/issues/445
[2] https://github.com/tree-sitter/tree-sitter/issues/4001
So now we have to keep track of line and column positions and
pass valid values to tree-sitter. (It adds quite some
complexity, but only linearly; one can ignore all the linecol
stuff when trying to understand treesit code and then come
back to it later.) Eli convinced me to disable tracking by
default, and only enable it for languages that needs it. So
the buffer starts out not tracking linecol. And when a
parser is created, if the language is in
treesit-languages-require-line-column-tracking, we enable
tracking in the buffer, and enable tracking for the parser.
To simplify things, once a buffer starts tracking linecol, it
never disables tracking, even if parsers that need tracking
are all deleted; and for parsers, tracking is determined at
creation time, if it starts out tracking/non-tracking, it
stays that way, regardless of later changes to
treesit-languages-require-line-column-tracking.
To make calculating line/column positons fast, we store
linecol caches for begv, point, and zv in the
buffer (buf->ts_linecol_cache_xxx); and in the parser object,
we store linecol cache for visible beg/end of that parser.
In buffer editing functions, we need the linecol for
start/old_end/new_end, those can be calculated by scanning
newlines (treesit_linecol_of_pos) from the buffer point
cache, which should be always near the point. And we usually
set the calculated linecol of new_end back to the buffer
point cache.
We also need to calculate linecol for the visible_beg/end for
each parser, and linecol for the buffer's begv/zv, these
positions are usually far from point, so we have caches for
all of them (in either the parser object or the buffer).
These positions are far from point, so it's inefficient to
scan newlines from point to there to get up-to-date linecol
for them; but in the same time, because they're far and
outside the changed region, we can calculate their change in
line and column number by simply counting how much newlines
are added/removed in the changed
region (compute_new_linecol_by_change).
