2021-07-15Revert "Add documentation on where to find async compatibile versions of ↵Evan Mesterhazy
ssh2-rs" This reverts commit 0d316d2f734a4ee03523f6001f5a1a4bb7535bc9. As of this commit, https://crates.io/crates/async-ssh2/0.1.2-beta is listed as deprecated on crates.io. I believe that the other alternative mentioned in the reverted commit, async-ssh2-lite, has at least two serious correctness issues and should not be recommended: 1. https://github.com/bk-rs/async-ssh2-lite/issues/9 2. https://github.com/bk-rs/async-ssh2-lite/issues/10 async-ssh2-lite is also lacking documentation and has no unit or integration tests to give confidence in its implementation. In my opinion, until such issues are resolved ssh2 should refrain from recommending either of these crates to avoid misleading users into believing that these implementations are tested and ready for production.
2021-02-01Expose libssh2_trace function (#209)Mike Harris
* Expose libssh2_trace function and associated constants, to allow enabling libssh2 trace output. * set LIBSSH2_WIN32 on windows build so that gettimeofday replacement will be compiled. * libssh2_trace actually returns int, even though the documentation says it returns void. This was causing systest to fail. Changed the FFI to match the C function. Co-authored-by: eharmic <michael.harris@ericsson.com>
2020-11-22Handle more precise SFTP error codes (#203)Matteo Bigoi
* Handle more precise SFTP error codes * Allow set-env in macos github action * Bump to 0.9 since the Error interface has changed, hence this is a breaking change

2020-01-29copy the error message obtained in last_errorYusuke Sasaki
The pointer obtained by `libssh2_session_last_error` points to the buffer that `LIBSSH2_SESSION` holds internally, so its contents may be overwritten by the next API call. This patch changes the data type for storing error messages inside `Error` from `&'static str` to `Cow<'static, str>`.

@richardwhiuk requested this. While it is safe to move to another thread, it will still lock internally, and if you are in blocking mode that may be undesirable.

2020-01-18remove now-unused Binding traitWez Furlong
2020-01-18Make properly Send safeWez Furlong
In earlier iterations I accidentally removed Send from Session and then later restored it in an unsafe way. This commit restructures the bindings so that each of the objects holds a reference to the appropriate thing to keep everything alive safely, without awkward lifetimes to deal with. The key to this is that the underlying Session is tracked by an Arc<Mutex<>>, with the related objects ensuring that they lock this before they call into the underlying API. In order to make this work, I've had to adjust the API around iterating both known hosts and agent identities: previously these would iterate over internal references but with this shift there isn't a reasonable way to make that safe. The strategy is instead to return a copy of the host/identity data and then later look up the associated raw pointer when needed. The purist in me feels that the copy feels slightly wasteful, but the realist justifies this with the observation that the cardinality of both known hosts and identities is typically small enough that the cost of this is in the noise compared to actually doing the crypto+network ops. I've removed a couple of error code related helpers from some of the objects: those were really internal APIs and were redundant with methods exported by the Error type anyway.

2020-01-18add shutdown and close methodsbold
This commit exposes the `shutdown` method of `Sft` and `close` method of `File` to free resources. Previously this was done synchronously and therefor not usable in async wrappers. Whith the methods exposed they can be polled until success. If successful a flag is set to notify the destructor that no resources need to be freed anymore. However, if resources were not cleaned up by calling `close` or `shutdown` the destructor will clean up synchronously.

2019-08-02tighten up `Session::rc`Wez Furlong
Previously, this function could return None even if passed an error result. This could happen in situations where no error had been recorded against the session object, but where libssh2 had returned an error condition anyway. It was also possible for the prior implementation to return the wrong information in a similar situation: if an error had been recorded against the session, that error would be returned rather than the current error code. This commit tidies up the implementation of this function by always returning an `Error` object that corresponds to the provided `rc` parameter. If the last error message recorded against the `Session` has a matching error value then that error message will be used, otherwise we'll synthesize one just from the error code.

Add a function to configure how extended data streams are to be handled. This allows for merging stderr to stdout, or discarding it.
