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 primarily intended as a counterpart to prepare. However, there are a few error cases where on_finish may be called when prepare has not. (These are considered bugs and may be fixed in the future, but for now you may need to check to see if the initialization work done in prepare has occurred)

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. There is no guarantee that prepare will be called if an error occurs that is handled by the framework.

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.

Added in version 3.1: Asynchronous support.

SYNC_LAYR_ADD: item is an empty tuple () SYNC_LAYR_DEL: item is an empty tuple () SYNC_NODEEDIT: item is (buid, form, ETYPE, VALS, META)) or (None, None, s_layer.EDIT_PROGRESS, (), ())

For edits in the past, events are yielded in offset order across all layers. For current data (wait=True), events across different layers may be emitted slightly out of offset order.

Note

Will not yield any values from layers created with logedits disabled

Parameters:

  • matchdef (Dict[str, Sequence[str]]) – a dict describing which events are yielded. See layer.syncIndexEvents for matchdef specification.

  • offsdict (Optional(Dict[str,int])) – starting nexus/editlog offset by layer iden. Defaults to 0 for unspecified layers or if offsdict is None.

  • wait (bool) – whether to pend and stream value until this layer is fini’d

async syncLayerNodeEdits(iden, offs, wait=True)[source]

Yield (offs, mesg) tuples for nodeedits in a layer.

async syncLayersEvents(offsdict=None, wait=True)[source]

Yield (offs, layriden, STYP, item, meta) tuples for nodeedits for all layers, interspersed with add/del layer messages.

STYP is one of the following constants:

SYNC_NODEEDITS: item is a nodeedits (buid, form, edits) SYNC_LAYR_ADD: A layer was added (item and meta are empty) SYNC_LAYR_DEL: A layer was deleted (item and meta are empty)

Parameters:

  • offsdict (Optional(Dict[str,int])) – starting nexus/editlog offset by layer iden. Defaults to 0 for unspecified layers or if offsdict is None.

  • wait (bool) – whether to pend and stream value until this layer is fini’d

synapse.glob module

synapse.glob.iAmLoop()[source]
synapse.glob.initloop()[source]
synapse.glob.setGreedCoro(loop: 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)

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

Bases: 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]
setBootUrls(urlinfo)[source]
async task(todo, name=None)[source]
async waitready(timeout=10)[source]
class synapse.telepath.ClientV2[source]

Bases: Base

A telepath client which:

  • connects to multiple services

  • distributes API calls across them

  • receives topology updates from AHA

NOTE: This must co-exist with Client until we eliminate uses that

attempt to call telepath APIs directly from the Client rather than awaiting a proxy()

class synapse.telepath.Genr[source]

Bases: 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: 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: Base

class synapse.telepath.Proxy[source]

Bases: 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)

class synapse.telepath.Share[source]

Bases: 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]
class synapse.telepath.TeleSSLObject(*args, **kwargs)[source]

Bases: SSLObject

do_handshake()[source]

Start the SSL/TLS handshake.

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.getAhaProxy(urlinfo)[source]

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

synapse.telepath.loadTeleCell(dirn)[source]
async synapse.telepath.loadTeleEnv(path)[source]
synapse.telepath.mergeAhaInfo(info0, info1)[source]
synapse.telepath.modurl(url, **info)[source]
async synapse.telepath.open(url, onlink=None)[source]

Open a new telepath ClientV2 object based on the given URL.

Parameters:

  • url (str) – The URL to connect to.

  • onlink – An optional async callback function to run when connections are made.

Notes

The onlink callback function has the call signature (proxy, urlinfo). The proxy is the Telepath Proxy object. The urlinfo is the parsed URL information used to create the proxy object. The urlinfo structure may change between versions of Synapse.

Returns:

A ClientV2 object.

Return type:

ClientV2

async synapse.telepath.openinfo(info)[source]
synapse.telepath.withTeleEnv()[source]
synapse.telepath.zipurl(info)[source]
