class synapse.axon.AxonHttpUploadV1(application: tornado.web.Application, request: tornado.httputil.HTTPServerRequest, **kwargs: Any)[source]

Bases: synapse.lib.httpapi.StreamHandler

async data_received(chunk)[source]

Implement this method to handle streamed request data.

Requires the .stream_request_body decorator.

May be a coroutine for flow control.

on_connection_close()[source]

Called in async handlers if the client closed the connection.

Override this to clean up resources associated with long-lived connections. Note that this method is called only if the connection was closed during asynchronous processing; if you need to do cleanup after every request override on_finish instead.

Proxies may keep a connection open for a time (perhaps indefinitely) after the client has gone away, so this method may not be called promptly after the end user closes their connection.

on_finish()[source]

Called after the end of a request.

Override this method to perform cleanup, logging, etc. This method is a counterpart to prepare. on_finish may not produce any output, as it is called after the response has been sent to the client.

async post()[source]

Called after all data has been read.

async prepare()[source]

Called at the beginning of a request before get/post/etc.

Override this method to perform common initialization regardless of the request method.

Asynchronous support: Use async def or decorate this method with .gen.coroutine to make it asynchronous. If this method returns an Awaitable execution will not proceed until the Awaitable is done.

New in version 3.1: Asynchronous support.

Many CoreApi methods operate on packed nodes consisting of primitive data structures which can be serialized with msgpack/json.

An example of a packaged Node:

( (<form>, <valu>), {

    "props": {
        <name>: <valu>,
        ...
    },

        "foo.bar": <time>,
    },
})

  • reqs (Union[Dict[str, Union[int, List[int]]], List[Dict[...]]]) – Either a dict of the fixed time fields or a list of such dicts. The keys are in the set (‘year’, ‘month’, ‘dayofmonth’, ‘dayofweek’, ‘hour’, ‘minute’. The values must be positive integers, except for the key of ‘dayofmonth’ in which it may also be a negative integer which represents the number of days from the end of the month with -1 representing the last day of the month. All values may also be lists of valid values.

synapse.glob module

synapse.glob.iAmLoop()[source]
synapse.glob.initloop()[source]
synapse.glob.setGreedCoro(loop: asyncio.events.AbstractEventLoop)[source]
synapse.glob.sync(coro, timeout=None)[source]

Schedule a coroutine to run on the global loop and return it’s result.

Parameters

coro (coroutine) – The coroutine instance.

Notes

This API is thread safe and should only be called by non-loop threads.

synapse.glob.synchelp(f)[source]

The synchelp decorator allows the transparent execution of a coroutine using the global loop from a thread other than the event loop. In both use cases, the actual work is done by the global event loop.

Examples

Use as a decorator:

@s_glob.synchelp
async def stuff(x, y):
    await dostuff()

Calling the stuff function as regular async code using the standard await syntax:

valu = await stuff(x, y)

Calling the stuff function as regular sync code outside of the event loop thread:

valu = stuff(x, y)

synapse.mindmeld module

synapse.telepath module

An RMI framework for synapse.

class synapse.telepath.Aware[source]

Bases: object

The telepath.Aware mixin allows shared objects to handle individual links managed by the Daemon.

async getTeleApi(link, mesg, path)[source]

Return a shared object for this link. :param link: A network link. :type link: synapse.lib.link.Link :param mesg: The tele:syn handshake message. :type mesg: (str,dict)

onTeleShare(dmon, name)[source]
class synapse.telepath.Client[source]

Bases: synapse.lib.base.Base

A Telepath client object which reconnects and allows waiting for link up.

Notes

The conf data allows changing parameters such as timeouts, retry period, and link pool size. The default conf data can be seen below:

conf = {
    'timeout': 10,
    'retrysleep': 0.2,
    'link_poolsize': 4,
}
async proxy(timeout=10)[source]

class synapse.telepath.Genr[source]

Bases: synapse.telepath.Share

class synapse.telepath.GenrIter(proxy, todo, share)[source]

Bases: object

An object to help delay a telepath call until iteration.

async list()[source]
class synapse.telepath.GenrMethod(proxy, name, share=None)[source]

Bases: synapse.telepath.Method

class synapse.telepath.Method(proxy, name, share=None)[source]

Bases: object

The telepath Method is used to provide proxy method calls.

class synapse.telepath.Pipeline[source]

Bases: synapse.lib.base.Base

class synapse.telepath.Proxy[source]

Bases: synapse.lib.base.Base

A telepath Proxy is used to call remote APIs on a shared object.

Example

import synapse.telepath as s_telepath

# open the “foo” object shared in a dmon on localhost:3344

async def doFooThing():

proxy = await s_telepath.openurl(’tcp://127.0.0.1:3344/foo’)

valu = await proxy.getFooValu(x, y)

The proxy (and openurl function) may also be used from sync code:

proxy = s_telepath.openurl(’tcp://127.0.0.1:3344/foo’)

valu = proxy.getFooValu(x, y)

async call(methname, *args, **kwargs)[source]

Call a remote method by name.

Parameters
  • methname (str) – The name of the remote method.

  • *args – Arguments to the method call.

  • **kwargs – Keyword arguments to the method call.

Most use cases will likely use the proxy methods directly:

The following two are effectively the same:

valu = proxy.getFooBar(x, y) valu = proxy.call(‘getFooBar’, x, y)

async getPipeline(genr, name=None)[source]

Construct a proxy API call pipeline in order to make multiple telepath API calls while minimizing round trips.

Parameters
  • genr (async generator) – An async generator that yields todo tuples.

  • name (str) – The name of the shared object on the daemon.

Example

def genr():

yield s_common.todo(‘getFooByBar’, 10) yield s_common.todo(‘getFooByBar’, 20)

for retn in proxy.getPipeline(genr()):

valu = s_common.result(retn)

async handshake(auth=None)[source]
async task(todo, name=None)[source]
async taskv2(todo, name=None)[source]
class synapse.telepath.Share[source]

Bases: synapse.lib.base.Base

The telepath client side of a dynamically shared object.

class synapse.telepath.Task[source]

Bases: object

A telepath Task is used to internally track calls/responses.

reply(retn)[source]
async result()[source]
async synapse.telepath.addAhaUrl(url)[source]

Add (incref) an aha registry URL.

NOTE: You may also add a list of redundant URLs.

synapse.telepath.alias(name)[source]

Resolve a telepath alias via ~/.syn/aliases.yaml

Parameters

name (str) – Name of the alias to resolve.

Notes

An exact match against the aliases will always be returned first. If no exact match is found and the name contains a ‘/’ in it, the value before the slash is looked up and the remainder of the path is joined to any result. This is done to support dynamic Telepath share names.

Returns

The url string, if present in the alias. None will be returned if there are no matches.

Return type

str

synapse.telepath.chopurl(url, **opts)[source]
async synapse.telepath.delAhaUrl(url)[source]

Remove (decref) an aha registry URL.

NOTE: You may also remove a list of redundant URLs.

async synapse.telepath.disc_consul(info)[source]

Support for updating a URL info dictionary which came from a protocol+consul:// URL.

Notes

This updates the info-dictionary in place, placing the host value into an original_host key, and updating host and port.

By default we pull the host value from the catalog Address value, and the port from the ServicePort value.

The following HTTP parameters are supported:

  • consul: This is the consul host (schema, fqdn and port) to connect to.

  • consul_tag: If set, iterate through the catalog results until a result is found which matches the tag value. This is a case sensitive match.

  • consul_tag_address: If set, prefer the TaggedAddresses from the catalog.

  • consul_service_tag_address: If set, prefer the associated value from the ServiceTaggedAddresses field.

  • consul_nosslverify: If set, disables SSL verification.

async synapse.telepath.getAhaProxy(urlinfo)[source]

Return a telepath proxy by looking up a host from an aha registry.

async synapse.telepath.loadTeleEnv(path)[source]
synapse.telepath.mergeAhaInfo(info0, info1)[source]
async synapse.telepath.openinfo(info)[source]
synapse.telepath.zipurl(info)[source]

Reconstruct a URL string from a parsed telepath info dict.
