This function is meant to work *exactly* as curl_easy_perform() but will
use the event-based libcurl API internally instead of
curl_multi_perform(). To avoid relying on an actual event-based library
and to not use non-portable functions (like epoll or similar), there's a
rather inefficient emulation layer implemented on top of Curl_poll()
instead.
There's currently some convenience logging done in curl_easy_perform_ev
which helps when tracking down problems. They may be suitable to remove
or change once things seem to be fine enough.
curl has a new --test-event option when built with debug enabled that
then uses curl_easy_perform_ev() instead of curl_easy_perform(). If
built without debug, using --test-event will only output a warning
message.
NOTE: curl_easy_perform_ev() is not part if the public API on purpose.
It is only present in debug builds of libcurl and MUST NOT be considered
stable even then. Use it for libcurl-testing purposes only.
runtests.pl now features an -e command line option that makes it use
--test-event for all curl command line tests. The man page is updated.
Implement wrappers around strtod to convert the user argument to a
double with sane error checking. Use this to allow --max-time and
--connect-timeout to accept decimal values instead of strictly integers.
The manpage is updated to make mention of this feature and,
additionally, forewarn that the actual timeout of the operation can
vary in its precision (particularly as the value increases in its
decimal precision).
In this change, --metalink option no longer takes argument. If
it is specified, given URIs are processed as Metalink XML file.
If given URIs are remote (e.g., http URI), curl downloads it
first. Regardless URI is local file (e.g., file URI scheme) or
remote, Metalink XML file is not written to local file system and
the received data is fed into Metalink XML parser directly. This
means with --metalink option, filename related options like -O
and -o are ignored.
Usage examples:
$ curl --metalink http://example.org/foo.metalink
This will download foo.metalink and parse it and then download
the URI described there.
$ curl --metalink file://foo.metalink
This will parse local file foo.metalink and then download the URI
described there.
This change adds experimental Metalink support to curl.
To enable Metalink support, run configure with --with-libmetalink.
To feed Metalink file to curl, use --metalink option like this:
$ curl -O --metalink foo.metalink
We use libmetalink to parse Metalink files.
Configuration files such as curl_config.h and all config-*.h no longer exist
nor are generated/copied into 'src' directory, now these only exist in 'lib'
directory from where curl tool sources uses them.
Additionally old src/setup.h has been refactored into src/tool_setup.h which
now pulls lib/setup.h
The possibility of a makefile needing an include path adjustment exists.
This new option tells curl to not work around a security flaw in the
SSL3 and TLS1.0 protocols. It uses the new libcurl option
CURLOPT_SSL_OPTIONS with the CURLSSLOPT_ALLOW_BEAST bit set.
Previously we required that -S/--show-error was used _after_
-s/--silent. This was slightly confusing since we strive to make
arguments as position independent as possible.
Now, you can use them in any order and the result should still be the
same.
