dbusclient - Client side DBus interactions
This manpage describes the dbusclient package which is a Tcl script extension that simplifies client side programing for access to services on the DBus.
The two TclOO class commands are exported from the dbusclient namespace and they form the subcommands of a namespace ensemble on the ::dbusclient namespace.
The Connection command creates a new instance and connects to the DBus specified by address. The return value of the commands is the fully qualified connection object command name, which is to be used when opening a service on the bus. On most systems where the DBus daemon is run, there are two well known busses named, system and session.
Connection create sysBus system
The Service command creates a new service instance for the service defined on the connobj bus. The return value of the commands is the fully qualified service object command name, which is to be used when accessing provided services. Although the service object may be named arbitrarily, it is most convenient to create a Service object that has the same name as the service with it accesses.
The following methods are available for Connection objects.
The destructor for a Connection object disconnects from the bus to which it was associated and cleans up any internal resources. Any Service objects using the connection are also destroyed.
The call method invokes the method method which belongs to the interface interface on the object instance specified by path which resides on the service target. The sig argument give the DBus signature for the method. If sig is specified as the empty string, no signature is used in the conversion of Tcl strings to the underlying data types required by method. The remaining argN arguments are passed as arguments to the method.
The listen method registers script to be invoked when signal on path is seen on the DBus. If script is not specified, the currently registered script is returned. If script is the empty string, then the currently registered script is removed. When script is invoked, a dictionary of the event details is supplied as an additional argument. See the dbus package documentation for the details of the event dictionary.
The following methods are available for Service objects.
The destructor for a Service object cleans up any internal resources.
The connectedTo method returns the Connection object command name for the service.
The pathList method returns a list of object instance path names for the service.
The findPathsByPropertyValue method returns a list of object path names specified by the interface and property arguments where expression also evaluates to true. The expression is evaluated in the context of the caller and may reference variables named Path, Interface, Property, Value, or Valid. The values of these variables is set for each property value that also matches the values of interface and property before expression is evaluated. This method provides a means of finding object paths whose property values match a specified expression. For example,
set conn [Connection create sysBus system] Service create DBus org.freedesktop.DBus $conn DBus findPathsByPropertyValue org.freedesktop.DBus Interfaces {"org.freedesktop.DBus.Monitoring" in $Value}
returns the object whose path is /org/freedesktop/DBus.
The pathInterfaces method returns a list of interfaces that are implemented for path.
The pathProperties method returns a list of property names that are implemented by interface for the object specified by path.
The interfaceMethods method returns a list of methods supported by the specified interface.
The methodSignature method returns the DBus signature string for the specified interface and method.
The interfaceProperties method returns a list of properties defined by interface.
The interfaceSignals method returns a list of signals defined by interface.
The call method invokes the method method that is contained in interface on the the object specified by path. Additional optional argN arguments are passes as arguments to the called method. The return value of the call method is the return value of the underlying service method from the DBus.
The property method reads and optionally updates the value of the property property for path that is part of interface. If value is specified, then property is set to that value (if possible). The return value of the method is the new value of property.
Note that writing property values to services on the DBus is an asynchronous operation and usually results in a property changed signal being sent. The dbusclient package handles such asynchronous updates but the Tcl event loop must be entered in order to do so.
The trace method causes Tcl commands to be executed when certain conditions on the DBus are met. The interface for this method is modeled after the core trace command. Legal operation argument values are:
The legal values for the type trace type are path, signal, or property. The return value of the command is a trace identifier, which can be used to remove or query the trace. Multiple traces may be added of any type and the parameters of the trace may be the same. Traces are executed in order from youngest (most recently added) to oldest.
Arranges for cmdprefix to be invoked whenever an object instance whose name matches pathpattern is added or removed from the service. The matching against pathpattern is done in the same manner as the string match command. When invoked, cmdprefix is supplied with two additional arguments, a status, which has a value of either added or removed, and the name of the added or removed path.
Arranges for cmdprefix to be invoked when the signal from interface on an object instance matching pathpattern is detected on the bus. The matching against pathpattern is done in the same manner as the string match command. When invoked, cmdprefix is supplied with additional arguments. The first argument is a dictionary of event information as described in the Event Handlers section of the dbus package documentation. Any arguments of the signal itself follow.
Arranges for cmdprefix to be invoked when the property associated with interface for an object instance matching pathpattern is reported. The matching against pathpattern is done in the same manner as the string match command. When invoked, cmdprefix is supplied with up to five additional arguments. The first argument is a status value of changed or invalidated, indicating if the property value has changed or is no longer valid. The second argument is the path name of the object instance whose property was affected. The third argument is the name of the interface of which the property was part. The fourth argument is the name of the property that was affected. If the status was changed, a fifth argument is supplied giving the new value of the property.
Removes the trace identified by traceid. It is not an error to remove a non-existant trace.
Returns a dictionary containing information about the trace specified by traceid. The keys of the dictionary are:
Specifies the type of trace as either path, signal, or property.
Specifies the pattern that object instance path names must match to trigger the trace.
Specifies the command prefix to invoke when the trace performed.
For signal type traces additional keys are:
Specifies the interface that will trigger the trace.
Specifies the name of the signal that will trigger the trace.
For property type traces additional keys are:
Specifies the interface that will trigger the trace.
Specifies the name of the property that will trigger the trace.
For path type traces no additional information is provided.
The waitForProperty method establishes a property trace on the property property in interface matching pathpattern. These arguments are interpreted in the same manner as for the trace add method. Then the script specified by trigger is executed in the call stack of the caller. Then the Tcl event loop is entered waiting for the property change to occur. If timeout is specified it is the number of milliseconds to wait for the property change notification. A timeout value of 0 is interpreted to mean to wait forever. The default timeout value is 5000. If trigger executes successfully and the DBus notification is received before any timeout, then the return value of the command is a dictionary giving the details of the property change. The keys to the dictionary are:
A status element value of changed, indicates the property value has changed and the new value is given by the value element. A status element value of invalidated, indicates the property no longer has a valid value and in this case no value element is included in the dictionary.
The path name of the object to which the change occurred.
The interface of the changed property.
The name of the changed property.
The new value of the property if the status element has a value of changed.
The waitForSignal method establishes a signal trace on the signal signal in interface matching pathpattern. These arguments are interpreted in the same manner as for the trace add method. Then the script specified by trigger is executed in the call stack of the caller. Then the Tcl event loop is entered waiting for the signal notification to occur. If timeout is specified it is the number of milliseconds to wait for the property change notification. A timeout value of 0 is interpreted to mean to wait forever. The default timeout value is 5000. If trigger executes successfully and the DBus signal is received before any timeout, then the return value of the command is a dictionary giving the details of the signal. The keys to the dictionary are:
The path name of the object to which the change occurred.
The interface of the changed property.
The name of the received signal.
The sender of the signal.
The argument signature of the signal.
A list of argument values that came with the signal.
The waitForPath method establishes a path trace on the object instance matching pathpattern. Then the script specified by trigger is executed in the call stack of the caller. Then the Tcl event loop is entered waiting for the path change to occur. If timeout is specified it is the number of milliseconds to wait for the property change notification. A timeout value of 0 is interpreted to mean to wait forever. The default timeout value is 5000. If trigger executes successfully and the DBus notification is received before any timeout, then the return value of the command is a dictionary giving the details of the path change. The keys to the dictionary are:
A status element value of added, indicates the path is newly created and the value is given by the path element. A status element value of removed, indicates the path was deleted and the value of the deleted path is given by the path element.
The path name of the object which was added or removed.
The dbusclient package depends upon three binary Tcl packages.
dbus is the Tcl bindings to the DBus library.
tcom is used to parse XML returned during introspection.
ral is used to manage the introspection data.
DBus


"My first experience using the internet is most likely a relatable one. I was in school, in Paris, and the teacher brought the entire class up to the computer room. I can't remember if the computers were just installed or if it was just the first time we where allowed to use them but I do recall that one particular student had some previous knowledge, mainly due to the fact that he knew how to bypass the school block and was able to get us straight to the most exciting games website. I remember the walls were orange but I have not the recollection of the computer we where using or what we were supposed to be doing (most likely something less exciting like WolframAlpha or paint). Once we got onto the games website I was blown away by the number of games I could play at my will, it was like an endless supply of fun to me and I was incredibly excited. It was clear at that moment that I had underestimated the internet. My mother had a Mac in the house which she mainly used to write, and I'm sure we had an internet connection at that time but I had never tried using it. To me, the computer was just a tool for work and there was nothing cool or desirable about that, I had no interest in them whatsoever. This obviously changed when I found all the games. Shooting aliens or just simple platformers… I was hooked. So that's my first real memory of using one and being excited by one. First, the thrill of being able to bypass the school block on forbidden websites then finding out that there where entire websites filled with thousands of games, my mind was blown."
"I'm not sure if this was the first time I interacted with the web but what I do remember was email using AOL. My brother and I were still really young (around 6) and we would draw a lot. My father lived in Switzerland while we were in Germany, so we often would fax our drawings. But that meant that my father always saw them in greyscale. Then we got an email account where we could scan and send our drawings to my father. He finally got to see them in color and we could respond to our "artwork". I remember being amazed by this and we were always very excited to check our email to see any comments (Mum always supervised us, she wasn't very trusting of the web!)"
"To be honest I don't remember the first time I used the internet because as I remember it always was there. Though, I remember some funny stories about how I was learning to understand what is it and how it works. So I am going to write about one of them. As I already mentioned, the Internet was existing since I was born, and when I was 5 years old I remember that my family had one super old computer, which looked like a big plastic box, and a more new version of computer, which was already quite flat. Everyone, of course, was using the new one because it was faster and better, and I, as the smallest person in the family was left to play with an old one. Apparently, the new computer was connected to the internet and I was observing my parents searching web, so I knew everything about how it looked inside and how to use it. Well, at least I thought that I knew everything. And one day, playing around the old computer I found the icon of Internet Explorer and I was sure that this icon means that I can access the internet. And being very excited about my discovery I decided to search for something. When I clicked on it nothing happened because the computer was not connected to any network but for a moment I thought that I broke something in the computer because I was thinking that you can install the "Internet" on your computer like all the other programs. I came to my parents with this story and they explained to me that the internet is not just one program."
"I got my first computer in 2005. Operation System was Windows XP but the internet very very low speed. Was called Dial-Up modem which made creepy sounds and if someone calling, the internet immediately shot down) After one year, finally we have wi-fi router. One friend told me Microsoft introduced a new operation system Windows 7. I looked in Microsoft website (and yes it was my first web site) and I saw that Microsoft offers to download a new Windows Media Player free. It took me almost 4 hours to get the .exe file. When I installed NEW WMP. That was a very different design from Windows XP and I liked it. At that moment I realized that web it's powerful “tool”."
"I'd loved computers for a long time, ever since I was introduced to them in grade school. Classrooms had old Macs in them where you could do dot-matrix printing and play Oregon Trail. We used them to draw and to learn. I stayed fascinated for years, but it was one day when I was 12 years old that my neighbor friend told me they got the internet. I had heard about the internet, that it connected you to information and that you could find pages about anything you could think of. I called him up and asked if I could come over. When I got there we ran straight upstairs to the office and sat down. He connected and the modem made all its weird sounds and then he opened up Netscape and I watched the first webpage load in slowly. Yahoo. There was the funny logo with the exclamation point. The list of blue links. There were categories for all kinds of things. We spent the next 4 hours clicking from category to category and from page to page, seeing what kinds of wild sites we could find. That evening I started my campaign of annoying my parents to death to get a computer for our home and it had to be one that could connect to the internet."
"I can remember quite well the first time that I used the web since I was actually waiting for finally "getting installed the internet” on my computer. It was in 2000 and I had to dial in via a modem (I'm old enough to remember the pre-flat rate time) and I couldn't wait to create an E-Mail account for being able to send my very first E-Mail to the only other one of my classmates that had Internet already at this time. Funnily this new way of communication & connecting people that the Internet provided was the most exciting purpose for me and shortly after we discovered the world of chatrooms and were totally amazed of the possibility to talk to people somewhere in real-time."

Networking and messaging¶
Corda uses AMQP/1.0 over TLS between nodes which is currently implemented using Apache Artemis, an embeddable message queue broker. Building on established MQ protocols gives us features like persistence to disk, automatic delivery retries with backoff and dead-letter routing, security, large message streaming and so on.
Artemis is hidden behind a thin interface that also has an in-memory only implementation suitable for use in unit tests and visualisation tools.
Note
A future version of Corda will allow the MQ broker to be split out of the main node and run as a separate server. We may also support non-Artemis implementations via JMS, allowing the broker to be swapped out for alternative implementations.
There are multiple ways of interacting with the network. When writing an application you typically won’t use the messaging subsystem directly. Instead you will build on top of the flow framework, which adds a layer on top of raw messaging to manage multi-step flows and let you think in terms of identities rather than specific network endpoints.
Network Map Service¶
Supporting the messaging layer is a network map service, which is responsible for tracking public nodes on the network.
Nodes have an internal component, the network map cache, which contains a copy of the network map (which is just a document). When a node starts up its cache fetches a copy of the full network map, and requests to be notified of changes. The node then registers itself with the network map service, and the service notifies subscribers that a new node has joined the network. Nodes do not automatically deregister themselves, so (for example) nodes going offline briefly for maintenance are retained in the network map, and messages for them will be queued, minimising disruption.
Nodes submit signed changes to the map service, which then forwards update notifications on to nodes which have requested to be notified of changes.
The network map currently supports:
- Looking up nodes by service
- Looking up node for a party
- Suggesting a node providing a specific service, based on suitability for a contract and parties, for example suggesting an appropriate interest rates oracle for an interest rate swap contract. Currently no recommendation logic is in place.
Message queues¶
The node makes use of various queues for its operation. The more important ones are described below. Others are used for maintenance and other minor purposes.
p2p.inbound : | The node listens for messages sent from other peer nodes on this queue. Only clients who are authenticated to be nodes on the same network are given permission to send. Messages which are routed internally are also sent to this queue (e.g. two flows on the same node communicating with each other). |
|---|---|
internal.peers.$identity : | |
These are a set of private queues only available to the node which it uses to route messages destined to other peers.
The queue name ends in the base 58 encoding of the peer’s identity key. There is at most one queue per peer. The broker
creates a bridge from this queue to the peer’s p2p.inbound queue, using the network map service to lookup the
peer’s network address. |
|
internal.services.$identity : | |
| These are private queues the node may use to route messages to services. The queue name ends in the base 58 encoding of the service’s owning identity key. There is at most one queue per service identity (but note that any one service may have several identities). The broker creates bridges to all nodes in the network advertising the service in question. When a session is initiated with a service counterparty the handshake is pushed onto this queue, and a corresponding bridge is used to forward the message to an advertising peer’s p2p queue. Once a peer is picked the session continues on as normal. | |
internal.networkmap : | |
This is another private queue just for the node which functions in a similar manner to the internal.peers.* queues
except this is used to form a connection to the network map node. The node running the network map service is treated
differently as it provides information about the rest of the network. |
|
rpc.requests : | RPC clients send their requests here, and it’s only open for sending by clients authenticated as RPC users. |
clients.$user.rpc.$random : | |
RPC clients are given permission to create a temporary queue incorporating their username ($user ) and sole
permission to receive messages from it. RPC requests are required to include a random number ($random ) from
which the node is able to construct the queue the user is listening on and send the response to that. This mechanism
prevents other users from being able listen in on the responses. |
Security¶
Clients attempting to connect to the node’s broker fall in one of four groups:
- Anyone connecting with the username
SystemUsers/Node
is treated as the node hosting the broker, or a logical component of the node. The TLS certificate they provide must match the one broker has for the node. If that’s the case they are given full access to all valid queues, otherwise they are rejected. - Anyone connecting with the username
SystemUsers/Peer
is treated as a peer on the same Corda network as the node. Their TLS root CA must be the same as the node’s root CA - the root CA is the doorman of the network and having the same root CA implies we’ve been let in by the same doorman. If they are part of the same network then they are only given permission to send to ourp2p.inbound
queue, otherwise they are rejected. - Every other username is treated as a RPC user and authenticated against the node’s list of valid RPC users. If that is successful then they are only given sufficient permission to perform RPC, otherwise they are rejected.
- Clients connecting without a username and password are rejected.
Artemis provides a feature of annotating each received message with the validated user. This allows the node’s messaging
service to provide authenticated messages to the rest of the system. For the first two client types described above the
validated user is the X.500 subject DN of the client TLS certificate and we assume the common name is the legal name of
the peer. This allows the flow framework to authentically determine the Party
initiating a new flow. For RPC clients
the validated user is the username itself and the RPC framework uses this to determine what permissions the user has.
Note
Party
lookup is currently done by the legal name which isn’t guaranteed to be unique. A future version will
use the full X.500 name as it can provide additional structures for uniqueness.
The broker also does host verification when connecting to another peer. It checks that the TLS certificate common name matches with the advertised legal name from the network map service.
Messaging types¶
Every Message
object has an associated topic and may have a session ID. These are wrapped in a TopicSession
.
An implementation of MessagingService
can be used to create messages and send them. You can get access to the
messaging service via the ServiceHub
object that is provided to your app. Endpoints on the network are
identified at the lowest level using SingleMessageRecipient
which may be e.g. an IP address, or in future
versions perhaps a routing path through the network.

The database I created is a movie database that holds both actors and movies. It allows users to add, edit, and delete actors from a table as well as add, edit, and delete movies from a table. These features are enabled through forms and extensions from a base webpage. Each page shares the same format and navigation bar on the top of the page.
I have created two tables: one for the Actors and one for the Movies. The columns in the Actors table are: name, about. The columns in the Movies table are: name, year, actor. It is a one to many relationship because one actor can be involved with many movies. The actor field in the movies table links the two tables together. (see README.md file for more detail)

54 (1998) 1 star out of 4
The people who populate the movie 54 are shallow, self-absorbed and self-indulgent. In other words, they perfectly mirror the era as well as the movie this feature depicts.
54 is the story of that well-publicized New York disco, Studio 54, the in-place in the '70s where anybody who was anybody went to be ogled, photographed and pampered.
The difficulty with 54, which was written and directed by Mark Christopher, is that his script takes no point of view. Christopher neither condemns nor glorifies the legendary excesses that were Studio 54's hallmark.
He keeps an uninvolved distance, thus keeping us from forming any emotional attachment with any of the protagonists.
The movie's one main asset is the surprising performance by Mike Myers as Steve Rubell, the famous owner of the nightspot. He is part rebel, part dreamer, part shrewd entrepreneur.
Myers, in his first straight character part, is in turn appealing and appalling. At one moment he can try to pressure a male employee into a sexual situation, then at the next moment apologize for his bad behavior and offer the young man a handful of cash.
The story is told by Shane O'Shea (Ryan Phillippe), a New Jersey lad who dreams of crossing the river to the Big Apple. Shades of John Travolta's Brooklyn-bound Tony in Saturday Night Fever.
Eventually, Shane does come to New York, attracts Rubell's eye and is admitted to the promised land. His looks get him a job as a busboy, and he is later promoted to the prestigious position of bartender, where he mixes with and makes drinks for the rich and famous.
Shane's dream is to meet soap star Julie Black (Neve Campbell), a fellow Garden Stater. But both characters are so sketchily drawn that even when they do hook up, it's no big deal. The chemistry between Shane and Julie is nonexistent.
54 is a very cold, uninvolving movie. It's all strobe lights and glitz, all substance. It's sort of like the musical era it covers.

The Gateway Server maintains connections with gateways supporting the UDP, MQTT, gRPC and Basic Station protocols. It forwards uplink traffic to Network Servers, and schedules downlink traffic on gateways.
Connectivity
Gateways can connect to Gateway Servers over multiple protocols.
Basic Station protocol
Gateways can connect to a Gateway Server using the Basic Station LNS protocol.
UDP protocol
Gateways can connect to a Gateway Server over the UDP protocol. The EUI that is sent with every message is used to identify the gateway.
If a gateway is found in the Identity Server with this EUI, messages are correlated to this gateway. Otherwise, depending on network configuration, uplinks may routed or dropped. However, the network will not send downlinks to this gateway, given that its regional parameters cannot be identified.
Many packet forwarders implementing the UDP protocol do not implement any queuing system for downlinks, resulting in packet loss since SX1301 concentrators cannot buffer multiple downlinks. The Things Stack therefore implements, for the UDP protocol, a delay to send downlinks to gateway just before they’re meant to be emitted by the concentrator. You can disable this feature individually per gateway, for example if the RTT between your gateway and the Gateway Server is too high.
MQTT protocol
Gateways can connect to a Gateway Server by exchanging protocol buffers over MQTT. MQTT is also available over TLS, providing confidentiality of messages exchanged between the gateway and the network. The encoding with protocol buffers reduces bandwidth usage compared to the UDP protocol, which uses JSON encoding.
Gateway Information
While a gateway is connected, the Gateway Server collects statistics about the messages exchanged with the gateway, and about the status messages sent by the gateway. Those statistics can be retrieved from the Gateway Server using its gRPC and HTTP APIs.
Communication with Network Server
The main function of the Gateway Server is to establish a stable connection with gateways, and to serve as a relay between those gateways and the Network Servers.
When routing an uplink, the Gateway Server decides which Network Server to send it to based on the DevAddr
of the device. Join request are similarly routed based on the DevEUI
of the device.
The Gateway Server exchanges with Network Servers over gRPC. It claims identifiers of gateways using ClaimIDs
and UnclaimIDs
in the cluster, and sends uplinks using HandleUplink
. It exposes an service with ScheduleDownlink
, that the Network Server uses to send downlinks to gateways.
Downlink Scheduling
The Gateway Server keeps track of all downlinks emitted and to be emitted by gateways connected to it. This allows the stack to do smarter scheduling. When the Network Server requests the Gateway Server to schedule a downlink message on a gateway, it checks the schedule to see if a downlink is possible:
- Downlink overlap: If the emission of a downlink overlaps the emission of another downlink, the downlink is refused.
- Time off air: Some frequency plans have time-off-air constraints, meaning a gateway must not emit for a certain period of time after emitting a downlink.
- Duty cycle: Many countries have duty cycle restrictions, prohibiting a device for emitting for more than a certain percentage of time on a certain band.
- Dwell time: Some countries, such as the United States, are subject to dwell time regulations - meaning the duration of a transmission can’t exceed a certain limit.

5 dead in KZN bus accident
by Nicole McCainFive people have died in a bus accident on the South Coast of KwaZulu-Natal.
The accident, which occurred on Saturday morning on the R56 near Rietvlei, saw paramedics treating another 42 patients.
Although the cause of the crash is not known, the bus appears to have veered off the road when the driver lost control, according to a SABC report.
KwaZulu-Natal Emergency Medical Services spokesperson Robert McKenzie confirmed the accident took place in the early hours of the morning.
"A bus left the road and crashed leaving five people fatally injured. Paramedics treated 42 patients at the scene of the crash for various injuries ranging from critical to minor," he added.
All patients were transported to nearby hospitals.
The exact cause of the accident is not known and police are investigating the circumstances, McKenzie said.

Recipe 9.7. Storing Per-Thread InformationCredit: John E. Barham, Sami Hangaslammi, Anthony Baxter ProblemYou need to allocate to each thread some storage that only that thread can use. SolutionThread-specific storage is a useful design pattern, and Python 2.3 did not yet support it directly. However, even in 2.3, we could code it up in terms of a dictionary protected by a lock. For once, it's slightly more general, and not significantly harder, to program to the lower-level thread module, rather than to the more commonly useful, higher-level tHReading module that Python offers on top of it: _tss = { } try: import thread except ImportError: # We're running on a single-threaded platform (or, at least, the Python # interpreter has not been compiled to support threads), so we just return # the same dict for every call -- there's only one thread around anyway! def get_thread_storage( ): return _tss else: # We do have threads; so, to work: _tss_lock = thread.allocate_lock( ) def get_thread_storage( ): """ Return a thread-specific storage dictionary. """ thread_id = thread.get_ident( ) _tss_lock.acquire( ) try: return _tss.set_default(thread_id, { }) finally: _tss_lock.release( ) Python 2.4 offers a much simpler and faster implementation, of course, thanks to the new tHReading.local function: try: import threading except ImportError: import dummy_threading as threading _tss = threading.local( ) def get_thread_storage( ): return _tss._ _dict_ _ DiscussionThe main benefit of multithreaded programs is that all of the threads can share global objects when they need to do so. Often, however, each thread also needs some storage of its ownfor example, to store a network or database connection unique to itself. Indeed, each such externally oriented object is generally best kept under the control of a single thread, to avoid multiple possibilities of highly peculiar behavior, race conditions, and so on. The get_thread_storage function in this recipe solves this problem by implementing the "thread-specific storage" design pattern, and specifically by returning a thread-specific storage dictionary. The calling thread can then use the returned dictionary to store any kind of data that is private to the thread. This recipe is, in a sense, a generalization of the get_transaction function from ZODB, the object-oriented database underlying Zope. One possible extension to this recipe is to add a delete_thread_storage function. Such a function would be useful, particularly if a way could be found to automate its being called upon thread termination. Python's threading architecture does not make this task particularly easy. You could spawn a watcher thread to do the deletion after a join with the calling thread, but that's a rather heavyweight approach. The recipe as presented, without deletion, is quite appropriate for the common and recommended architecture in which you have a pool of (typically daemonic) worker threads (perhaps some of them general workers, with others dedicated to interfacing to specific external resources) that are spawned at the start of the program and do not go away until the end of the whole process. When multithreading is involved, implementation must always be particularly careful to detect and prevent race conditions, deadlocks, and other such conflicts. In this recipe, I have decided not to assume that a dictionary's set_default method is atomic (meaning that no thread switch can occur while set_default executes)adding a key can potentially change the dictionary's whole structure, after all. If I was willing to make such an assumption, I could do away with the lock and vastly increase performance, but I suspect that such an assumption might make the code too fragile and dependent on specific versions of Python. (It seems to me that the assumption holds for Python 2.3, but, even if that is the case, I want my applications to survive subtle future changes to Python's internals.) Another risk is that, if a thread terminates and a new one starts, the new thread might end up with the same thread ID as the just-terminated one, and therefore accidentally share the "thread-specific storage" dictionary left behind by the just-terminated thread. This risk might be mitigated (though not eliminated) by providing the delete_thread_storage function mentioned in the previous paragraph. Again, this specific problem does not apply to me, given the kind of multithreading architecture that I use in my applications. If your architecture differs, you may want to modify this recipe's solution accordingly. If the performance of this recipe's version is insufficient for your application's needs, due to excessive overhead in acquiring and releasing the lock, then, rather than just removing the lock at the risk of making your application fragile, you might consider an alternative: _creating_threads = True _tss_lock = thread.allocate_lock( ) _tss = { } class TssSequencingError(RuntimeError): pass def done_creating_threads( ): """ switch from thread-creation to no-more-threads-created state """ global _creating_threads if not _creating_threads: raise TssSequencingError('done_creating_threads called twice') _creating_threads = False def get_thread_storage( ): """ Return a thread-specific storage dictionary. """ thread_id = thread.get_ident( ) # fast approach if thread-creation phase is finished if not _creating_threads: return _tss[thread_id] # careful approach if we're still creating threads try: _tss_lock.acquire( ) return _tss.setdefault(thread_id, { }) finally: _tss_lock.release( ) This variant adds a boolean switch _creating_threads, initially true. As long as the switch is true, the variant uses a careful locking-based approach, quite similar to the one presented in this recipe's Solution. At some point in time, when all threads that will ever exist (or at least all that will ever require access to get_thread_storage) have been started, and each of them has obtained its thread-local storage dictionary, your application calls done_creating_threads. This sets _creating_threads to False, and every future call to get_thread_storage then takes a fast path where it simply indexes into global dictionary _tssno more acquiring and releasing the lock, no more creating a thread's thread-local storage dictionary if it didn't yet exist. As long as your application can determine a moment in which it can truthfully call done_creating_threads, the variant in this subsection should definitely afford a substantial increase in speed compared to this recipe's Solution. Note that it is particularly likely that you can use this variant if your application follows the popular and recommended architecture mentioned previously: a bounded set of daemonic, long-lived worker threads, all created early in your program. This is fortunate, because, if your application is performance-sensitive enough to worry about the locking overhead of this recipe's solution, then no doubt you will want to structure your application that way. The alternative approach of having many short-lived threads is generally quite damaging to performance. If your application needs to run only under Python 2.4, you can get a much simpler, faster, and solid implementation by relying on the new threading.local function. threading.local returns a new object on which any thread can get and set arbitrary attributes, independently from whatever getting and setting other threads may be doing on the same object. This recipe, in the 2.4 variant, returns the per-thread _ _dict_ _ of such an object, for uniformity with the 2.3 variant. This way, your applications can be made to run on both Python 2.3 and 2.4, using the best version in each case: import sys if sys.version >= '2.4': # insert 2.4 definition of get_local_storage here else: # insert 2.3 definition of get_local_storage here The 2.4 variant of this recipe also shows off the intended use of module dummy_threading, which, like its sibling dummy_thread, is also available in Python 2.3. By conditionally using these dummy modules, which are available on all platforms, whether or not Python was compiled with thread support, you may sometimes, with due care, be able to write applications that can run on any platform, taking advantage of threading where it's available but running anyway even where threading is not available. In the 2.3 variant, we did not use the similar approach based on dummy_thread, because the overhead would be too high to pay on nonthreaded platforms; in the 2.4 variant, overhead is pretty low anyway, so we went for the simplicity that dummy_threading affords. See AlsoFor an exhaustive treatment of the design pattern that describes thread-specific storage (albeit aimed at C++ programmers), see Douglas Schmidt, Timothy Harrisson, Nat Pryce, Thread-Specific Storage: An Object Behavioral Pattern for Efficiently Accessing per-Thread State (http://www.cs.wustl.edu/~schmidt/PDF/TSS-pattern.pdf); the Library Reference documentation dummy_thread, dummy_threading, and Python 2.4's tHReading.local; ZODB at http://zope.org/Wikis/ZODB/FrontPage. |

As you surmise, it contains a substance of incalculable value—the first practical preparation of Zapt's Repulsive Paste.'… Sargent crossed to gaze into the little bucket his fiancée was holding. ‘Does look sort of repulsive,’ he agreed after a glance at the mess in the bottom of the pail. 'But—you mean this stuff is responsible for Fluffy's sudden elevation in life?' ” — J U Giesy, Zapt's Repulsive Paste

Learn how to convert your html into a dynamic realtime application.
Collaborative Elements
Simply define a collection and a name.
<input data-collection='my-profile' name='firstname'>
Typing in the input will generate a document in the collection specified and the name will contain the value.
<input data-collection='my-profile' data-document_id="generated_id" name='firstname'>
Copy the generated document_id and reuse it to edit that value. Add it to any html element and display the value. Apply contenteditable attribute and edit the value from any element.
Forms

If form realtime false it will require submitBtn
You will have the option to set realtime as true or false. If data-realtime set to false then the form will require a button to save.
<button class="submitBtn"> </button>
Inputs

Dem Rep Himes: 'Forget Quid Pro Quo' -- Trump ‘Extorted’ Ukraine Like a ‘Mob Boss’ | Breitbart
by Pam KeyOn Sunday’s “Meet The Press” on NBC, Rep. Jim Himes (D-CT) said that “quid pro quo” was not the correct term to describe the actions of President Donald Trump during his dealings with Ukraine.
Himes said, “Let’s forget quid pro quo. It’s one of these things to muddy the works.”
He continued, “When are you trying to persuade the American people of something really pretty simple, which is that the president acted criminally and extorted in the way a mob boss would extort somebody, a vulnerable foreign country it is probably best not to use Latin words to explain it.”
He added, “Extortion doesn’t require a ‘you give me this and I’ll give you that kind of quid pro quo’ It simply requires using your muscle to get something that you don’t have a right to. By the way, the crowning absurdity is, they’re all pretty much admitting–because Ambassador Sondland has refreshed his recollection–they are all basically admitting there was a quid pro quo, go, but gosh it wasn’t that bad, it was exactly the same thing as Joe Biden and Hillary Clinton. Look, we got to get off this quid pro quo thing because it’s complicated.”
