It cannot actually return an error, so the parent function does not need
to check for error and have an exit path that cannot be reached.

Closes#18855
To simplify dependencies, and sync tunits and units builds further.
`curlcheck.h` already depended on logic implemented within libtests:
it referenced a global variable (`unitfail`) defined in `first.c` and
declared in `test.h`.
Also:
- rename to `unitcheck.h` to indicate it's meant for unit tests.
- make `unitcheck.h` include `first.h` instead of `test.h`.
This brings header use closer to libtests. It also includes
`curlx/curlx.h` for all unit tests by default now.
- move `unitfail` declaration from `test.h` to `first.h`.
To match its definition in `first.c`.
- drop now redundant per-test curlx header includes.
Closes#17868
Make test bundles the default. Drop non-bundle build mode.
Also do all the optimizations and tidy-ups this allows, simpler builds,
less bundle exceptions, streamlined build mechanics.
Also rework the init/deinit macro magic for unit tests. The new method
allows using unique init/deinit function names, and calling them with
arguments. This is in turn makes it possible to reduce the use of global
variables.
Note this drop existing build options `-DCURL_TEST_BUNDLES=` from cmake
and `--enable-test-bundles` / `--disable-test-bundles` from autotools.
Also:
- rename test entry functions to have unique names: `test_<testname>`
This removes the last exception that was handled in the generator.
- fix `make dist` to not miss test sources with test bundles enabled.
- sync and merge `tests/mk-bundle.pl` into `scripts/mk-unity.pl`.
- mk-unity.pl: add `--embed` option and use it when `CURL_CLANG_TIDY=ON`
to ensure that `clang-tidy` does not miss external test C sources.
(because `clang-tidy` ignores code that's #included.)
- tests/unit: drop no-op setup/stop functions.
- tests: reduce symbol scopes, global macros, other fixes and tidy-ups.
- tool1621: fix to run, also fix it to pass.
- sockfilt: fix Windows compiler warning in certain unity include order,
by explicitly including `warnless.h`.

Using a mixture of techniques to avoid symbols collisions:
- reduce scope.
- add `t*_` / `T*_` prefix.
- move shared functions to `testutil.c`.
(`suburl()`, `rlim2str()`)
- clone re-used lib*.c sources.
(lib587, lib645)
- include shared symbols just once in re-used `lib*.c` sources.
(using `LIB*_C` guards.)
- drop re-used `lib*.c` sources where they were identical or
unused.
- make macros global.
- #undef macros before use.
What remain is the entry functions `test`, and `unit_setup`,
`unit_stop` in unit tests.
Also:
- fix formatting and other minor things along the way.
- add `const` where possible.
- sync some symbol names between tests.
- drop `mk-bundle-hints.sh` that's no longer necessary.
Closes#17468
- cmake: disable test bundles for clang-tidy builds.
clang-tidy ignores #included .c sources, and incompatible with unity
and bundles. It caused clang-tidy ignoring all test sources. It also
means this is the first time tests sources are checked with
clang-tidy. (autotools doesn't run it on tests.)
- cmake: update description for `CURL_TEST_BUNDLES` option.
- fix tests using special `CURLE_*` enums that were missing from
`curl/curl.h`. Add them as reserved codes.
- fix about ~50 other issues detected by clang-tidy: unchecked results,
NULL derefs, memory leaks, casts to enums, unused assigments,
uninitialized `errno` uses, unchecked `open`, indent, and more.
- drop unnecessary casts (lib1533, lib3207).
- suppress a few impossible cases with detailed `NOLINT`s.
- lib/escape.c: drop `NOLINT` no longer necessary.
Follow-up to 72abf7c13a#13862 (possibly)
- extend two existing `NOLINT` comments with details.
Follow-up to fabfa8e402#15825Closes#16756
Before this patch, the result code was a mixture of `int` and
`CURLcode`.
Also adjust casts and fix a couple of minor issues found along the way.
Cherry-picked from #13489Closes#13600
Also make the user and password arguments mandatory, since all code
paths in libcurl used them anyway.
Adapted unit test case 1620 to the new rules.
Closes#13584
Curl_read/Curl_write clarifications
- replace `Curl_read()`, `Curl_write()` and `Curl_nwrite()` to 1clarify
when and at what level they operate
- send/recv of transfer related data is now done via
`Curl_xfer_send()/Curl_xfer_recv()` which no longer has
socket/socketindex as parameter. It decides on the transfer setup of
`conn->sockfd` and `conn->writesockfd` on which connection filter
chain to operate.
- send/recv on a specific connection filter chain is done via
`Curl_conn_send()/Curl_conn_recv()` which get the socket index as
parameter.
- rename `Curl_setup_transfer()` to `Curl_xfer_setup()` for naming
consistency
- clarify that the special CURLE_AGAIN handling to return `CURLE_OK`
with length 0 only applies to `Curl_xfer_send()` and CURLE_AGAIN is
returned by all other send() variants.
SingleRequest reshuffling
- move functions into request.[ch]
- differentiate between reset and free
- add Curl_req_done() to perform last actions
- add a send `bufq` to SingleRequest for future use in keeping upload data
Closes#12963
- they are mostly pointless in all major jurisdictions
- many big corporations and projects already don't use them
- saves us from pointless churn
- git keeps history for us
- the year range is kept in COPYING
checksrc is updated to allow non-year using copyright statements
Closes#10205
Add licensing and copyright information for all files in this repository. This
either happens in the file itself as a comment header or in the file
`.reuse/dep5`.
This commit also adds a Github workflow to check pull requests and adapts
copyright.pl to the changes.
Closes#8869
More connection cache accesses are protected by locks.
CONNCACHE_* is a beter prefix for the connection cache lock macros.
Curl_attach_connnection: now called as soon as there's a connection
struct available and before the connection is added to the connection
cache.
Curl_disconnect: now assumes that the connection is already removed from
the connection cache.
Ref: #4915Closes#5009
We use "conn" everywhere to be a pointer to the connection.
Introduces two functions that "attaches" and "detaches" the connection
to and from the transfer.
Going forward, we should favour using "data->conn" (since a transfer
always only has a single connection or none at all) to "conn->data"
(since a connection can have none, one or many transfers associated with
it and updating conn->data to be correct is error prone and a frequent
reason for internal issues).
Closes#3442
