When a download size is known and rate limiting is in effect, adjust the
duration of each measurement step and its rate for maximum precision.
Since it is unpredictable how long the last bytes of a download will
take, download speed can be thrown off if the "last bytes" are a
significant amount of the total download. Make the "last bytes" small in
comparision to the rest and "stretch" the rate limit intervals to
accommodate the difference.
Fix ngtcp2 receive data acknowldgements to be based on a local window
size tracking. This allows window updates controlled by rate limits.
Fix ratelimit wait time calculation to accomodate negative tokens.
h3 rate limit, update timeers
Make download rate limits work correctly in ngtcp2. Fix multi handling
of rate limits to set a timer for when limits will update again.
Without running the transfer on limit updates, protocols like h2/h3 may
stall if the server does not send due to stream windows being too small.
scorecard: measure download speedlimits
When running scorecard with --limit-rate=n, show the reported download
speed averages plus percentage deviation from the limit.

This makes the easy handle 432 bytes smaller (totally 5352 bytes on my

now allocated only when needed.
Closes#20260
Avoid using PRIu32 and PRId32 in product source code. We don't need it.
It reduces readability. It is also inconsistent since unsigned int has
the same size and does not require the define.
DJGPP warns about using %u for uint32_t by default because it seems to
typedef it to unsigned long instead of unsigned int. Which even that is
annoying since long and int are both 32 bit on this platform.
We use our own *printf() implementation and we know this is safe.
This work-around defines uint32_t for DJGPP into unsigned int to avoid
the warnings and thus the need to use PRIu32 and PRId32.
Closes#20215
- Each time field is now 7 characters wide, so that the total width
never exceeds 79 columns so that it works correctly also in Windows
terminals. The title lines are adjusted accordingly.
This is accomplished by using h:mm:ss style up to 10 hours, and for
longer periods switch to "nnX nnY" style output. For hours, days,
months and years.
For less than one hour, the hour field is now dropped.
When no time info is provided, the field is now space-only. No more
`-:--:--`.
Also fixed the output for really long times which previously was
completely broken. The largest time now shows as ">99999y". (Becase
I can't figure out a better way).
- For sizes, the widths are now properly fixed to 6 characters. When
displaying a unit with less than 3 digits, it shows two decimal
precision like "16777215 => 15.99M" and one decmal otherwise: "262143
=> 255.9k"
Also fixes the decimal math. 131071 is 127.9k, which it previously did
not show.
- The time and size field outputs are now properly verified in test
1636.

Closes#20018
Use `data->progress.now` as the timestamp of proecssing a transfer.
Update it on significant events and refrain from calling `curlx_now()`
in many places.
The problem this addresses is
a) calling curlx_now() has costs, depending on platform. Calling it
every time results in 25% increase `./runtest` duration on macOS.
b) we used to pass a `struct curltime *` around to save on calls, but
when some method directly use `curx_now()` and some use the passed
pointer, the transfer experienes non-linear time. This results in
timeline checks to report events in the wrong order.
By keeping a timestamp in the easy handle and updating it there, no
longer invoking `curlx_now()` in the "lower" methods, the transfer
can observer a steady clock progression.

Closes#19833
Before this patch curl used the C preprocessor to override standard
memory allocation symbols: malloc, calloc, strdup, realloc, free.
The goal of these is to replace them with curl's debug wrappers in
`CURLDEBUG` builds, another was to replace them with the wrappers
calling user-defined allocators in libcurl. This solution needed a bunch
of workarounds to avoid breaking external headers: it relied on include
order to do the overriding last. For "unity" builds it needed to reset
overrides before external includes. Also in test apps, which are always
built as single source files. It also needed the `(symbol)` trick
to avoid overrides in some places. This would still not fix cases where
the standard symbols were macros. It was also fragile and difficult
to figure out which was the actual function behind an alloc or free call
in a specific piece of code. This in turn caused bugs where the wrong
allocator was accidentally called.
To avoid these problems, this patch replaces this solution with
`curlx_`-prefixed allocator macros, and mapping them _once_ to either
the libcurl wrappers, the debug wrappers or the standard ones, matching
the rest of the code in libtests.
This concludes the long journey to avoid redefining standard functions
in the curl codebase.
Note: I did not update `packages/OS400/*.c` sources. They did not
`#include` `curl_setup.h`, `curl_memory.h` or `memdebug.h`, meaning
the overrides were never applied to them. This may or may not have been
correct. For now I suppressed the direct use of standard allocators
via a local `.checksrc`. Probably they (except for `curlcl.c`) should be
updated to include `curl_setup.h` and use the `curlx_` macros.
This patch changes mappings in two places:
- `lib/curl_threads.c` in libtests: Before this patch it mapped to
libcurl allocators. After, it maps to standard allocators, like
the rest of libtests code.
- `units`: before this patch it mapped to standard allocators. After, it
maps to libcurl allocators.
Also:
- drop all position-dependent `curl_memory.h` and `memdebug.h` includes,
and delete the now unnecessary headers.
- rename `Curl_tcsdup` macro to `curlx_tcsdup` and define like the other
allocators.
- map `curlx_strdup()` to `_strdup()` on Windows (was: `strdup()`).
To fix warnings silenced via `_CRT_NONSTDC_NO_DEPRECATE`.
- multibyte: map `curlx_convert_*()` to `_strdup()` on Windows
(was: `strdup()`).
- src: do not reuse the `strdup` name for the local replacement.
- lib509: call `_strdup()` on Windows (was: `strdup()`).
- test1132: delete test obsoleted by this patch.
- CHECKSRC.md: update text for `SNPRINTF`.
- checksrc: ban standard allocator symbols.

-1.

Windows CRTs have a `share.h`. Before this patch when trying to

Also rename `lib/share.c` to keep matching the header.

Description of how this works in `docs/internal/RATELIMITS.ms`.
Notable implementation changes:
- KEEP_SEND_PAUSE/KEEP_SEND_HOLD and KEEP_RECV_PAUSE/KEEP_RECV_HOLD
no longer exist. Pausing is down via blocked the new rlimits.
- KEEP_SEND_TIMED no longer exists. Pausing "100-continue" transfers
is done in the new `Curl_http_perform_pollset()` method.
- HTTP/2 rate limiting implemented via window updates. When
transfer initiaiting connection has a ratelimit, adjust the
initial window size
- HTTP/3 ngtcp2 rate limitin implemnented via ack updates
- HTTP/3 quiche does not seem to support this via its API
- the default progress-meter has been improved for accuracy
in "current speed" results.
