This change fixes a regression where redirect body would needlessly be
decompressed even though it was to be ignored anyway. As it happens this
causes secondary issues since there appears to be a bug in apache2 that
it in certain conditions generates a corrupt zlib response. The
regression was created by commit:

I couldn't reproduce with the oss-fuzz original test case, but looking

So far, the code tries to pick an authentication method only if
user/password credentials are available, which is not the case for
Bearer authentictation...
Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
Closes#2754
The Bearer authentication was added to cURL 7.61.0, but there is a
problem: if CURLAUTH_ANY is selected, and the server supports multiple
authentication methods including the Bearer method, we strongly prefer
that latter method (only CURLAUTH_NEGOTIATE beats it), and if the Bearer
authentication fails, we will never even try to attempt any other
method.
This is particularly unfortunate when we already know that we do not
have any Bearer token to work with.
Such a scenario happens e.g. when using Git to push to Visual Studio
Team Services (which supports Basic and Bearer authentication among
other methods) and specifying the Personal Access Token directly in the
URL (this aproach is frequently taken by automated builds).
Let's make sure that we have a Bearer token to work with before we
select the Bearer authentication among the available authentication
methods.

It was previously erroneously skipped in some situations.
libtest/libntlmconnect.c wrongly depended on wrong behavior (that it
would get a zero timeout) when no handles are "running" in a multi
handle. That behavior is no longer present with this fix. Now libcurl
will always return a -1 timeout when all handles are completed.
Closes#2733
Commit 38203f1585 changed engine detection to be version-based,
with a baseline of openssl 1.0.1. This does in fact break builds
with openssl 1.0.0, which has engine support - the configure script
detects that ENGINE_cleanup() is available - but <openssl/engine.h>
doesn't get included to declare it.
According to upstream documentation, engine support was added to
mainstream openssl builds as of version 0.9.7:
https://github.com/openssl/openssl/blob/master/README.ENGINE
This commit drops the version test down to 1.0.0 as version 1.0.0d
is the oldest version I have to test with.

Given the contstraints of SChannel, I'm exposing these as the algorithms
themselves instead; while replicating the ciphersuite as specified by
OpenSSL would have been preferable, I found no way in the SChannel API
to do so.
To use this from the commandline, you need to pass the names of contants
defining the desired algorithms. For example, curl --ciphers
"CALG_SHA1:CALG_RSA_SIGN:CALG_RSA_KEYX:CALG_AES_128:CALG_DH_EPHEM"

If configure detects fnmatch to be available, use that instead of our

different. Test case 1307 is adjusted for these differences.

OpenSSL has supported --cacert for ages, always accepting LF-only line
endings ("Unix line endings") as well as CR/LF line endings ("Windows
line endings").
When we introduced support for --cacert also with Secure Channel (or in
cURL speak: "WinSSL"), we did not take care to support CR/LF line
endings, too, even if we are much more likely to receive input in that
form when using Windows.
Let's fix that.
Happily, CryptQueryObject(), the function we use to parse the ca-bundle,
accepts CR/LF input already, and the trailing LF before the END
CERTIFICATE marker catches naturally any CR/LF line ending, too. So all
we need to care about is the BEGIN CERTIFICATE marker. We do not
actually need to verify here that the line ending is CR/LF. Just
checking for a CR or an LF is really plenty enough.
