The layout of crates.io means that code blocks overflow after 60
characters, so wrap before 60 to avoid needing a scrollbar.
Remove the warning about the Agent code. I think after our recent
testing, I believe it's good enough that it doesn't need a separate
warning.
Remove the old-style macro-use directive and the extern crate directive.
Since tls and native-tls are mutually exclusive, we can't use
all-features anymore. Instead we enumerate the features needed to
build the docs for docs.rs.
The reference to time::Instant under feature = socks-proxy was
incorrectly scoped, and should have been just Instant. This breaks the
doc build and any builds that use feature = socks-proxy.
time_until_deadline had a time of check to time of use problem - the
deadline could pass between a call to checked_duration_since and the
evaluation of `deadline - now` (which panics if the result would be
negative). Resolve that by flipping the order of
checked_duration_since's arguments and using the result rather than
ignoring it.
Also there were three places that called deadline - now(), which could
panic. Replace those with time_until_deadline().
Adds limit of 100 connections to ConnectionPool. This is implemented
with a VecDeque acting as an LRU. When the pool becomes full, the oldest
stream is popped off the back from the VecDeque and also removed from
the map of PoolKeys to Streams.
Fixes#77
This loads a list of top domain names (e.g. from
https://tranco-list.eu/) and tries to fetch them all, in parallel. This
can be used to exercise ureq and find panics.
PoolKey calls unwrap() on an option that can be None. Specifically, the
local variable `port` can be None when PoolKey is constructed with a Url
whose scheme is unrecognized in url.port_or_known_default().
To fix that, make port an Option. Also, make scheme part of the PoolKey.
This prevents, for instance, a stream opened for `https://example.com:9999`
being reused on a request for `http://example.com:9999`.
Remove the test-only pool.get() accessor. This was used in only one test,
agent_pool in range.rs. This seemed like it was testing the agent more
than it was testing ranges, so I moved it to agent.rs and edited to
remove the range-testing parts.
Also, reject unrecognized URLs earlier in connect_socket so they don't
reach try_get_connection.
This also reverts a change to send_body that was originally added to
return the number of bytes written. It's no longer needed now that we
check the size of the reader in advance.
Fixes#76.
In https://github.com/algesten/ureq/pull/67#issuecomment-647112883,
Shnatsel points out that there are uses for read_timeout vs timeout. For
instance, when downloading a large file it's useful to have a read
timouet in case the download stalls, but it would be hard to pick a good
overall timeout without knowing the size of the file and the bandwidth
of the connection.
* Update documentation.
Synchronize goals section between README and rustdoc, and add two goals
(blocking API; no unsafe) that were mentioned elsewhere in the README.
Add error handling to examples for the module and for the Response
object.
And a section on synthetic errors to the top-level module documentation.
* Add back missing close brace.
* Add main function that returns Result.
* Add links to send_bytes and send_form.
* Document chunked encoding for send.
* Use a larger vec of bytes for send.
Adds some feature guards, and removes an unnecessary feature guard
around a call to connect_https (there's an implementation available for
non-TLS that returns UnknownScheme).
Also, remove unnecessary agent.state() method that was only available in
TLS builds. The state field is directly accessible within the crate, and
can be used in both TLS and non-TLS builds.

This deprecates timeout_read() and timeout_write() in favor of
timeout(). The new timeout method on Request takes a Duration instead
of a number of milliseconds, and is measured against overall request
time, not per-read time.
Once a request is started, the timeout is turned into a deadline
specific to that call. The deadline is used in conjunction with the
new DeadlineStream class, which sets a timeout on each read according
to the remaining time for the request. Once the request is done,
the DeadlineStream is unwrapped via .into::<Stream>() to become
an undecorated Stream again for return to the pool. Timeouts on the
stream are unset at this point.
Still to be done:
Add a setting on Agent for default timeout.
Change header-writing code to apply overall deadline rather than
per-write timeout.
Fixes#28.
Fix up cfg attributes to work on an xor basis.
Previously, the cfg(any()) attributes would cause issues when
both native-tls and tls features were enabled. Now, https functions
and enum variants will only be created when tls xor native-tls are
enabled. Additionally, a compile error has been added for when
both tls and native-tls features are enabled.
This test was making requests to a server on the Internet. That has the
potential to make the test flaky. Also, the test was relying on a
specific behavior from that server (timing out after 2s), which it no
longer exhibits.
This sets up a local test server that exhibits the specific properties
needed for this test.
This builds on 753d61b. Before we send a request, we can do a 1-byte
nonblocking peek on the connection. If the server has closed the
connection, this will give us an EOF, and we can take the connection out
of the pool before sending any request on it. This will reduce the
likelihood that we send a non-retryable POST on an already-closed
connection.
The server could still potentially close the connection between when we
make this check and when we finish sending the request, but this should
handle the majority of cases.
If DNS resolves to multiple IPs but the service is only running on one
of them and it isn't teh first IP, a connection will fail.
This was detected via running vault that would only bind to IPv4 but
localhost was returning ::1 followed by 127.0.0.1.
After this fix, the service connects without problem.
