Closes#21280
To sync names for the same macro logic between lib and src, and to move
it to the curlx namespace, to match `curlx_free()` that it's calling.
Closes#21151
Curl_1st_err() does not return the second error if the first result is
CURLE_AGAIN. This may cause errors to not become noticeable when they
should be.
Replace all use of Curl_1st_err() with Curl_1st_fatal(), which handles
CURLE_AGAIN as a not-a-real-error case.
Closes#20980
Introduce `Curl_xfer_is_secure(data)` that returns TRUE for transfers
that happen(ed) over a end-to-end secured connection, e.g. SSL.
Add test1586 to verify behaviour for http: transfers via a https: proxy.

Closes#20951
Add protocol.h and protocol.c containing all about libcurl's
known URI schemes and their protocol handlers (so they exist).
Moves the scheme definitions from the various sources files into
protocol.c. Schemes are known and used, even of the protocol
handler is not build or just not implemented at all.
Closes#20906
Improve the name, type and handling of `data->req.keepon`:
- Rename `keepon` to `io_flags`
- make `io_flags` and `uint8_t` and reposition in struct
- Rename `KEEP_*` defines to `REQ_IO_*`, move to request.h
- Replace all direct bit tests to `CURL_REQ_WANT_*` use
- Replace all direct bit manipulations with new macros
Closes#20905
Convert more `int port` to `uint16_t` port types. Reshuffle ports in
connectdata to save some bytes. Change `conn->destination` format to
- make it more readable and thus usable in tracing
- add the IPv6 scope_id only when not default (global)
and make it resemble more the textual format for IPv6
(e.g. suffix '%<scope_id>')
Closes#20918
Eliminate `conn->bits.ipv6_ip`
The bit was only correct for the first transfer using a connection. Use
`data->state.up.hostname` instead in places that need the URL hostname
in its original form.
Fix parseurlandfillconn() to not modify `data->state.up.hostname` before
copying the connection's hostname, but modify the copy instead, leaving
the URL hostname intact.
Closes#20919
Follow-up to 04289c62de. Regression shipped in 8.13.0.
- a logic error made it not loop and thus only match if the searched string
was first
- it no longer matches a substring
Adjusted test 1 to use multiple values in the Connection: response
header. Adjusted test 1542 to have a "Connection: close-not" which
should not match.

Closes#20894
Also:
- support per-directory and per-upper-directory whitelist entries.
- convert badlist input grep tweak into the above format.
(except for 'And' which had just a few hits.)
- fix many code exceptions, but do not enforce.
(there also remain about 350 'will' uses in lib)
- fix badwords in example code, drop exceptions.
- badwords-all: convert to Perl.
To make it usable from CMake.
- FAQ: reword to not use 'will'. Drop exception.
Closes#20886
The protocol handler method `connection_check` allowed to variable
operations to trigger with variable result bits. Only the `CONNCHECK_ISDEAD`
and `CONNRESULT_DEAD` were in use. Transform the function into
`connection_is_dead` without extra parameter and a bool result.
- Remove defines for `CONNCHECK_*` and `CONNRESULT_*`
- Rename protocol function in handler comments
- Change RTSP implementation (only protocol that uses this)
Closes#20890
It's mostly a filler word. I've read through each use of it in the code
base and did minor rephrasings when "simply" carried some meaning. The
overwhelming majority of cases, removing it improved the text
significantly. Inspired by #20793.
Closes#20822
- replaced double spaces with single space where applicable
- replaced "favourite" with "favorite"
- added language identifiers to code blocks in markdown files
- added extra line after code blocks and after headings in markdown
files
Cloes #20748
- vms/curlmsg_vms.h: delete unused/commented code.
- vtls/schannel_verify: sort includes.
- typecheck-gcc.h: fix indent and alignment.
- lib/config-win32.h: drop idle `#undef`.
- spacecheck: check for stray empty lines before after curly braces.
- make literals more readable: 1048576 -> 1024 * 1024
- scope variables.
- use ISO date in a comment.
- drop redundant parentheses.
- drop empty comments.
- unfold lines.
- duplicate/stray spaces in comments.
- fix indent, whitespace, minor typos.
Closes#20690
- fix internal macro `AN_APPLE_OS` reused between sources without
resetting it. It may potentially have left the system sha256
function unused.
- fix to define `WOLFSSL_OPTIONS_IGNORE_SYS` so that it always applies
to wolfSSL headers, also during feature detection.
- md4, md5, sha256: simplify fallback logic.
- delete 20+ unused macros.
- scope or move macros to avoid `-Wunused-macros` warnings.
- examples: delete unused code.
The warning detects macros defined but not used within the same C
source. It does not warn for macros defined in headers. It also works
with unity builds, but to a lesser extent.
Closes#20593
- de-dupe lib/src strdup/memdup functions into curlx.
- introduce `CURLX_STRDUP_LOW()` for mapping `strdup()`, and to do it at
one place within the code, in `curl_setup.h`.
- tests/server: use `curlx_strdup()`. (Also to fix building without
a system `strdup()`.)
- curlx/curlx.h: shorten and tidy up.
- adjust Windows build path to not need `HAVE_STRDUP`.
- build: stop detecting `HAVE_STRDUP` on Windows.
Closes#20497
And a few variables around.
There remain cases where the accepted pointer is const, yet the returned
pointer is written to.
Partly addressing (glibc 2.43):
```
* For ISO C23, the functions bsearch, memchr, strchr, strpbrk, strrchr,
strstr, wcschr, wcspbrk, wcsrchr, wcsstr and wmemchr that return
pointers into their input arrays now have definitions as macros that
return a pointer to a const-qualified type when the input argument is
a pointer to a const-qualified type.

Ref: #20420Closes#20421
When the compiler supports C99.
- map logging functions to macro stubs when verbose logging is disabled
and the compiler is C99. Make sure these stubs silence unused variable
warnings for non-variadic arguments.
Before this patch they mapped to function stubs, the same codepath
used for C89 compiler in this configuration.
- introduce new macros to tell the compiler which code to include
when verbose code is active, or inactive:
- `CURLVERBOSE`: defined when verbose code is active.
To enclose blocks of code only used for verbose logging.
- `VERBOSE(statement);`:
compile statement when verbose code is active.
To mark code lines only used for verbose logging.
- `NOVERBOSE(statement);`:
compile statement when verbose code is inactive.
To suppress warnings for arguments passed to logging functions via
printf masks, e.g. `NOVERBOSE((void)ipaddress);`, yet keeping
the warning in verbose builds.
Note these macros are not the same as `CURL_DISABLE_VERBOSE_STRINGS`.
Verbose code is always active in C89 mode (without variadic macro
support).
- drop existing uses of `CURL_DISABLE_VERBOSE_STRINGS` where redundant,
or replace with the above macros. Ending up reducing the number of
`#ifdef`s, and also the number of lines.

Fixes#20341
Refs: #12105#12167Closes#20353
This allows builds know about all schemes - but only have the protocol
implementations for those actually built-in.
It further allows multiple protocols to reuse the same protocol setup
and functions for both TLS and non-TLS implementations instead of
needing two (or more) structs.
The scheme information is now in 'struct Curl_scheme' and all the
function pointers for each scheme/protocol implementation are in struct
Curl_protocol.
The URL API now always work with all known protocols.
Closes#20351
Add casts to `bool`, or use `bit` type in local variables, where
neccessary to avoid MSVC compiler warnings C4242.
Note: There may remain places needing the above updates, where not
tested in CI, and missed in manual review.
Also:
- urldata: convert struct field `connect_only` to bitfield to match its
counterpart in another struct.
- rename curl-specific `bit` type to `curl_bit`.
Closes#20142
For protocols: dict, file, gopher, tftp, http, mqtt, smb.
Move protocol hander table to the end of sources, rearrange static
functions is reverse dependency order as necessary.
Closes#20274
This makes the easy handle 432 bytes smaller (totally 5352 bytes on my
rather maximized Linux 64 bit build). The 440 byte mimepost struct is
now allocated only when needed.
Closes#20260
In particular, it turns 'unsigned long' into 'uint32_t' since the code
needs to build and run just as fine on Windows which has 32 bit longs,
so we know the code works with 32 bit field versions.
This makes Curl_easy 56 bytes smaller on my 64 bit Linux (maximized
build).
Closes#20209
Note: This patch doesn't aim to add `timeval.h` includes missing from
local headers using `curltime` type. They remain relying on `urldata.h`
being included first. This patch also doesn't delete existing, used
includes already present in local headers (as internal users may rely
on them).
Ref: #20106Closes#20126
- asyn-thrdd.c: scope an include.
- apply more clang-format suggestions.
- tidy-up PP guard comments.
- delete empty line from the top of headers.
- add empty line after `curl_setup.h` include where missing.
- fix indent.
- CODE_STYLE.md: add `strcpy`.
Follow-up to 8636ad55df#20088
- lib1901.c: drop unnecessary line.
Follow-up to 436e67f65b#20076Closes#20070
- drop unused `http.h` includes.
- drop unused `http1.h` include.
- drop unused `http2.h` includes.
- vssh/ssh.h: drop unused `vssh.h` include.
- urldata.h: drop unused protocol includes.
- url: include `smtp.h` directly.
- rtsp.h: include directly where used.
- imap, smtp: drop redundant include, move another from .h to .c.
Verified with an all non-unity CI run.

Update test 1941 to verify this
Remove unused code from dynhds for handling folded headers, and the
associated unit tests of those functions in test 2602 and 2603.
Closes#20080
- replace `sendf.h` with `curl_trc.h` where it was included just for it.
- drop unused `curl_trc.h` includes.
- easy: delete obsolete comment about `send.h` include reason.
Also:
- move out `curl_trc.h` include from `sendf.h` and include it directly
in users, where not done already. To flatten the include tree and
to less rely on indirect includes.
- stop including `sendf.h` from other headers, replace it with forward
declaration of `Curl_easy`, as done already elsewhere.
Verified with an all non-unity CI run.
Closes#20061
To make it available for all files. Drop includes from individual
sources. This header was already included from most sources and not
specific to any internal subsystem.
Also to ensure that two system symbol redefines on Windows (`read()` and
`write()`) get applied to all sources. Move them to `curl_setup.h`.
