When the method is updated inside libcurl we must still not change the
method as set by the user as then repeated transfers with that same
handle might not execute the same operation anymore!
This fixes the libcurl part of #5462
Test 1633 added to verify.
Closes#5499
This test verifies the -w %json output and the test case includes a full
generated "blob". If there's no proxy support built into libcurl, it
will return an error for proxy related info variables and they will not
be included in the json, thus causing a mismatch and this test fails.

If `index.html` does not exist in the directory from which the example
is invoked, the fopen(upload, "rb") invocation in `setup` would fail,
returning NULL. This value is subsequently passed as the FILE* argument
of the `fread` invocation in the `read_callback` function, which is the
actual cause of the crash (apparently `fread` assumes that argument to
be non-null).
In addition, mitigate some possible crashes of similar origin.
Closes#5463
`http_proxy` will not be available in `conndata` if `CURL_DISABLE_PROXY`

This also includes the following changes:
- Use the same timeout for all jobs on Linux (60 minutes)
and Windows (90 minutes)
- Use CLI stable apt-get install -y instead of apt install
which warns about that and run apt-get update first
- Enable MQTT for Windows msys2 builds instead of
legacy msys1 builds
- Add ./configure --prefix parameter to the msys2 builds
- The MSYSTEM environment variable is now preset inside
the container images for the msys2 builds
Note: on Azure Pipelines the matrix strategy is basically
just a simple list of job copies and not really a matrix.

... and free it as soon as the transfer is done. It removes the extra
alloc when a new size is set with setopt() and reduces memory for unused
easy handles.
In addition: the closure_handle now doesn't use an allocated buffer at
all but the smallest supported size as a stack based one.

Due to bad escaping of the test code, the test wouldn't build and thus
result in a negative test result, which would lead to the unconditional
assumption that overwriting the arguments doesn't work and thus curl
would never hide credentials given in the command line, even when it
would otherwise be possible.
Regression from commit 2d4c2152c (7.60.0)
Reported-by: huzunhao on github
Fixes#5470Closes#5471
Tested with ngtcp2 built against the OpenSSL library. Additionally
tested with MultiSSL (NSS for TLS and ngtcp2+OpenSSL for QUIC).
The TLS backend (independent of QUIC) may or may not already have opened
the keylog file before. Therefore Curl_tls_keylog_open is always called
to ensure the file is open.
Tested following the same curl and tshark commands as in commit
"vtls: Extract and simplify key log file handling from OpenSSL" using
WolfSSL v4.4.0-stable-128-g5179503e8 from git master built with
`./configure --enable-all --enable-debug CFLAGS=-DHAVE_SECRET_CALLBACK`.
Full support for this feature requires certain wolfSSL build options,
see "Availability note" in lib/vtls/wolfssl.c for details.
Closes#5327
Create a set of routines for TLS key log file handling to enable reuse
with other TLS backends. Simplify the OpenSSL backend as follows:
- Drop the ENABLE_SSLKEYLOGFILE macro as it is unconditionally enabled.
- Do not perform dynamic memory allocation when preparing a log entry.
Unless the TLS specifications change we can suffice with a reasonable
fixed-size buffer.
- Simplify state tracking when SSL_CTX_set_keylog_callback is
unavailable. My original sslkeylog.c code included this tracking in
order to handle multiple calls to SSL_connect and detect new keys
after renegotiation (via SSL_read/SSL_write). For curl however we can
be sure that a single master secret eventually becomes available
after SSL_connect, so a simple flag is sufficient. An alternative to
the flag is examining SSL_state(), but this seems more complex and is
not pursued. Capturing keys after server renegotiation was already
unsupported in curl and remains unsupported.
Tested with curl built against OpenSSL 0.9.8zh, 1.0.2u, and 1.1.1f
(`SSLKEYLOGFILE=keys.txt curl -vkso /dev/null https://localhost:4433`)
against an OpenSSL 1.1.1f server configured with:
# Force non-TLSv1.3, use TLSv1.0 since 0.9.8 fails with 1.1 or 1.2
openssl s_server -www -tls1
# Likewise, but fail the server handshake.
openssl s_server -www -tls1 -Verify 2
# TLS 1.3 test. No need to test the failing server handshake.
openssl s_server -www -tls1_3
Verify that all secrets (1 for TLS 1.0, 4 for TLS 1.3) are correctly
written using Wireshark. For the first and third case, expect four
matches per connection (decrypted Server Finished, Client Finished, HTTP
Request, HTTP Response). For the second case where the handshake fails,
expect a decrypted Server Finished only.
tshark -i lo -pf tcp -otls.keylog_file:keys.txt -Tfields \
-eframe.number -eframe.time -etcp.stream -e_ws.col.Info \
-dtls.port==4433,http -ohttp.desegment_body:FALSE \
-Y 'tls.handshake.verify_data or http'
A single connection can easily be identified via the `tcp.stream` field.
For HTTP 1.x, it's a protocol error when the server sends more bytes
than announced. If this happens, don't reuse the connection, because the
start position of the next response is undefined.
