free dating sites in qatar [email protected]1999-06-07 Upon cursory reading of the rfc 2518 sec 8.10.4 through 8.11 I was confused by the plethoria of error codes. Nothing seems to unify them.
8.10.4 speaks of a return code of 409 Conflict if a lock can't be granted.
- Firstly, I can't tell if it is saying that the 409 is within the multistatus body... or in the response header.
- Secondly, later text seems to use a different status codes and never mentions this one again.
8.10.7 lists status codes
- 200 OK, 412 Precondition Failed, and 423 Locked are listed, but 409 Conflict (mentioned above) is not.
- In the case of 412 Precondition Failed, the description the follows doesn't seem to describe a "precondition failed". And it sounds like it's talking about an access request that includes a "locktoken", not a LOCK request that generates one.
- The 423 Locked condition also sort of sounds like it's talking about an access request rather than a LOCK request.
8.10.10 lists LOCK status codes
- 207 Multistatus which was not mentioned above
- 403 Forbidden which was not mentioned above.
- 424 Failed dependency which was not mentioned above.
8.11 UNLOCK
- we don't mention what the failure response should look like.
- comment: 200 OK seems like a better response than 204 No Content. The brief explanation isn't persuasive and seems to say that the response code should serve the purpose of the Content-Length. header.
- we should probably explicitly say if an UNLOCK can only be done on the original resource... and will fail even if the resource specified is locked by virtue of being a child of the original resource. Or is this too obvious? I know it's something easy to goof up in an implementation.
free dating sites in qld [email protected]2004-06-04 (1) 8.10.4 is wrong. The return code is 207. See issue 037_DEEP_LOCK_ERROR_STATUS, resolved in draft 01.
(2) General agreement that descriptions of error marshalling needs to be redone. This applies both th LOCK and UNLOCK.
(3) Agreement that the argument given for 204 is lame; clients should handle all 2xx status codes with the notable exception of 207 as "success". We may want to explain that in RFC2518bis' section about 207.
2004-07-10Resolution: Resolved after cleaning up error marshalling descriptions and rewriting the statement about UNLOCK and status 204.

chat rooms barrie ontario 063_LOCKS_SHOULD_THEY_USE_AN_IF_HEADER_TO_VERIFY   (type: change, status: closed)
free dating websites in qatar [email protected] Is the complexity of the IF header appropriate for the simple task o verifying that a client knowingly owns a lock? The IF header seems to serve a different purpose. One of those purposes is for the server to verify that you have the lock token (and that you know the root of it?). Another is for the client to check some preconditions before doing an action. Another seems to be to specify what lock to refresh in a lock refresh request. This seems to create ambiguity in our definition of the semantics of the IF: header.
freshsingle de wirklich kostenlos [email protected] It is felt by the group that it's important that the client not just own and hold the lock token, but that it also know where the lock is rooted before it does tasks related to that lock. This still leaves the lock referesh issue unresolved.
www.single.de kostenlos [email protected]2004-06-02 Re.: using Lock-Token to identify the lock to be refreshed (single mit kind sucht eva): problems with current rfc2518bis-05 wording; also no support in popular implementations; suggestion to roll-back changes in -bis and keep "If" header based syntax.

Resolution: Resolved to flag the locking errors at the source resource that was affected by the problem. The details of how to describe the error was deferred to a subsequent version of WebDAV. - 6/15/02 - 2518bis does not reflect this.
partnerbörse für singles mit hund seriöse partnervermittlung schweiz youtube   (type: change, status: open)
The method of describing the details of (beyond what resolved by COPYMOVE_LOCKED_STATUS_CODE_CLARIFICATION) of the underlying cause of various locking and ACL COPY/MOVE problems is deferred. Two proposals were outlined in the discussion, but interest was not great and we clearly don't have interoperability to take these proposals forward.

frauen suchen nach männer This document describes the "locking" extension to the Web Distributed Authoring and Versioning (WebDAV) protocol that allows to keep more than one person from working on a document at the same time. This helps preventing the "lost update problem," in which modifications are lost as first one author then another writes changes without merging the other author's changes.singles im alltag kennenlernen

partnervermittlung salzburg heute A "precondition" of a method describes the state on the server that must be true for that method to be performed. A "postcondition" of a method describes the state on the server that must be true after that method has completed. If a method precondition or postcondition for a request is not satisfied and unless a more specific HTTP status code applies, the response status of the request MUST be either 403 (Forbidden) if the request should not be repeated because it will always fail, or 409 (Conflict) if it is expected that the user might be able to resolve the conflict and resubmit the request.pakistani chat rooms like yahoo

partnersuche 40 plus preis In order to allow better client handling of error responses, a distinct XML element type is associated with each method precondition and postcondition of a request. When a particular precondition is not satisfied or a particular postcondition cannot be achieved, the appropriate XML element MUST be returned as the child of a top-level DAV:error element in the response body, unless otherwise negotiated by the request. In a 207 Multi-Status response, the DAV:error element would appear in the appropriate DAV:responsedescription element.online dating erstes date begrüßung

partnersuche 40 plus preisvergleich The ability to lock a resource provides a mechanism for serializing access to that resource. Using a lock, an authoring client can provide a reasonable guarantee that another principal will not modify a resource while it is being edited. In this way, a client can prevent the "lost update" problem.online dating kostenlos nrw

kontakt partnervermittlung salzburg This specification allows locks to vary over two client-specified parameters, the number of principals involved (exclusive vs. shared) and the type of access to be granted. This document defines locking for only one access type, write. However, the syntax is extensible, and permits the eventual specification of locking for other access types.partnersuche berlin frau sucht frau

partnervermittlung salzburg kostenlos The most basic form of lock is an exclusive lock. This is a lock where the access right in question is only granted to a single principal. The need for this arbitration results from a desire to avoid having to merge results.seriöse partnervermittlung schweiz test

singlebörse ohne premium mitgliedschaft clipmyhorse However, there are times when the goal of a lock is not to exclude others from exercising an access right but rather to provide a mechanism for principals to indicate that they intend to exercise their access rights. Shared locks are provided for this case. A shared lock allows multiple principals to receive a lock. Hence any principal with appropriate access can get the lock.partnerbörse 40 plus anleitung

free dating sites in hungary With shared locks there are two trust sets that affect a resource. The first trust set is created by access permissions. Principals who are trusted, for example, may have permission to write to the resource. Among those who have access permission to write to the resource, the set of principals who have taken out a shared lock also must trust each other, creating a (typically) smaller trust set within the access permission write set.partnerbörse 40 plus aktualisieren

free dating site in hamburg Starting with every possible principal on the Internet, in most situations the vast majority of these principals will not have write access to a given resource. Of the small number who do have write access, some principals may decide to guarantee their edits are free from overwrite conflicts by using exclusive write locks. Others may decide they trust their collaborators will not overwrite their work (the potential set of collaborators being the set of principals who have write permission) and use a shared lock, which informs their collaborators that a principal may be working on the resource.partnerbörse 40 plus dating

free dating websites in hungary This specification does not need to provide all of the communications paths necessary for principals to coordinate their activities. When using shared locks, principals may use any out of band communication channel to coordinate their work (e.g., face-to-face interaction, written notes, post-it notes on the screen, telephone conversation, Email, etc.) The intent of a shared lock is to let collaborators know who else may be working on a resource.partnersuche frau sucht frau lena

free dating sites in holland Shared locks are included because experience from web distributed authoring systems has indicated that exclusive locks are often too rigid. An exclusive lock is used to enforce a particular editing process: take out an exclusive lock, read the resource, perform edits, write the resource, release the lock. This editing process has the problem that locks are not always properly released, for example when a program crashes, or when a lock owner leaves without unlocking a resource. While both timeouts and administrative action can be used to remove an offending lock, neither mechanism may be available when needed; the timeout may be long or the administrator may not be available. With a shared lock, another user can at least take out another shared lock and start modifying the resource.partnerbörse 40 plus treff

free dating sites in hyderabad The current lock state of a resource is given in the leftmost column, and lock requests are listed in the first row. The intersection of a row and column gives the result of a lock request. For example, if a shared lock is held on a resource, and an exclusive lock is requested, the table entry is "false", indicating the lock must not be granted.

free dating site in holland A WebDAV compliant server is not required to support locking in any form. If the server does support locking it may choose to support any combination of exclusive and shared locks for any access types.online dating kostenlos ab 16

free dating sites in houston The reason for this flexibility is that locking policy strikes to the very heart of the resource management and versioning systems employed by various storage repositories. These repositories require control over what sort of locking will be made available. For example, some repositories only support shared write locks while others only provide support for exclusive write locks while yet others use no locking at all. As each system is sufficiently different to merit exclusion of certain locking features, this specification leaves locking as the sole axis of negotiation within WebDAV.date movie online kostenlos anschauen

virtual sim dating games online free A lock token is a type of state token, represented as a URI, which identifies a particular lock (see [RFC2518], section 9.4, for a definition of state tokens).

partnersuche frauen osteuropa Since server lock support is optional, a client trying to lock a resource on a server can either try the lock and hope for the best, or perform some form of discovery to determine what lock capabilities the server supports. This is known as lock capability discovery. Lock capability discovery differs from discovery of supported access control types, since there may be access control types without corresponding lock types.

Instead, this specification defines the new methods LOCK (creating and refreshing locks, see partnervermittlung jobs york) and UNLOCK (removing locks, see partnervermittlung jobs youtube) that act indirectly on locks.

junge frauen suchen reiche männer Owner information is kept with the lock so that it can be returned in the DAV:lockdiscovery property upon request. Note that this information is entirely client-controlled, thus a server MUST store the information faithfully just like if it appeared in a WebDAV dead property (see [RFC2518], section 4).

partnersuche 40 plus treff In general, a lock expires after a certain amount of time. This time can be specified in the LOCK creation request (however servers are not required to honor this request).

single mit kind partnersuche kostenlos If the timeout expires then the lock may be lost. Specifically, if the server wishes to harvest the lock upon time-out, the server SHOULD act as if an UNLOCK method was executed by the server on the resource using the lock token of the timed-out lock, performed with its override authority. Thus logs should be updated with the disposition of the lock, notifications should be sent, etc., just as they would be for an UNLOCK request.

partnervermittlung agentur deutschland The timers used for timeout expiry can be reset by the client by submitting a LOCK refresh request.

partnervermittlung deutschland akademiker Servers are advised to pay close attention to the values submitted by clients, as they will be indicative of the type of activity the client intends to perform. For example, an applet running in a browser may need to lock a resource, but because of the instability of the environment within which the applet is running, the applet may be turned off without warning. As a result, the applet is likely to ask for a relatively small timeout value so that if the applet dies, the lock can be quickly harvested. However, a document management system is likely to ask for an extremely long timeout because its user may be planning on going off-line.

partnersuche regensburg kostenlos online A client MUST NOT assume that just because the time-out has expired the lock has been lost. Clients MUST assume that locks may arbitrarily disappear at any time, regardless of the value given in the Timeout header. The Timeout header only indicates the behavior of the server if "extraordinary" circumstances do not occur. For example, an administrator may remove a lock at any time or the system may crash in such a way that it loses the record of the lock's existence.

suchen männer frauen wie ihre mutter Although the locking mechanisms specified here provide some help in preventing lost updates, they cannot guarantee that updates will never be lost. Consider the following scenario:wo treffen sich singles in mönchengladbach

  • Two clients A and B are interested in editing the resource 'index.html'. Client A is an HTTP client rather than a WebDAV client, and so does not know how to perform locking.
  • Client A doesn't lock the document, but does a GET and begins editing.
  • Client B does LOCK, performs a GET and begins editing.
  • Client B finishes editing, performs a PUT, then an UNLOCK.
  • Client A performs a PUT, overwriting and losing all of B's changes.

www frauen suchen männer There are several reasons why the WebDAV protocol itself cannot prevent this situation. First, it cannot force all clients to use locking because it must be compatible with HTTP clients that do not comprehend locking. Second, it cannot require servers to support locking because of the variety of repository implementations, some of which rely on reservations and merging rather than on locking. Finally, being stateless, it cannot enforce a sequence of operations like LOCK / GET / PUT / UNLOCK.singles mönchengladbach kostenlos

russische frauen in deutschland suchen männer WebDAV servers that support locking can reduce the likelihood that clients will accidentally overwrite each other's changes by requiring clients to lock resources before modifying them.

partnervermittlungen in deutschland If a request would modify the content for a locked resource, a dead property of a locked resource, a live property that is defined to be lockable for a locked resource, or an internal member URI of a locked collection, the request MUST fail unless the lock-token for that lock is submitted in the request. An internal member URI of a collection is considered to be modified if it is added, removed, or identifies a different resource. partnervermittlung salzburg orf [yourlove christliche singles chemnitz: Copy of GULP, "Locked State". --reschke]

online dating nach dem ersten date While those without a write lock may not alter a property on a resource it is still possible for the values of live properties to change, even while locked, due to the requirements of their schemas. Only dead properties and live properties defined to respect locks are guaranteed not to change while write locked.

partnersuche ravensburg umgebung heute casual dating seite deutschland

free dating sites interracial A write lock on a collection, whether created by a "Depth: 0" or "Depth: infinity" lock request, prevents the addition or removal of member URIs of the collection by non-lock owners. As a consequence, when a principal issues a PUT or POST request to create a new resource under a URI which needs to be an internal member of a write locked collection to maintain HTTP namespace consistency, or issues a DELETE to remove an internal member URI of a write locked collection, this request MUST fail if the principal does not have a write lock on the collection.

free dating sites in italy However, if a write lock request is issued to a collection containing member URIs identifying resources that are currently locked in a manner which conflicts with the write lock, the request MUST fail with a 423 (Locked) status code (Note that this can only occur for a request of a "Depth: infinity" write lock).

online dating free app If a lock owner causes the URI of a resource to be added as an internal member URI of a "Depth: infinity" locked collection then the new resource MUST be automatically added to the lock. This is the only mechanism that allows a resource to be added to a write lock. Thus, for example, if the collection /a/b/ is write locked and the resource /c is moved to /a/b/c then resource /a/b/c will be added to the write lock.

partnersuche ohne registrierung schweiz youtube online date kostenlos xp

best online dating free apps If a user agent is not required to have knowledge about a lock when requesting an operation on a locked resource, the following scenario might occur. Program A, run by User A, takes out a write lock on a resource. Program B, also run by User A, has no knowledge of the lock taken out by Program A, yet performs a PUT to the locked resource. In this scenario, the PUT succeeds because locks are associated with a principal, not a program, and thus program B, because it is acting with principal A's credential, is allowed to perform the PUT. However, had program B known about the lock, it would not have overwritten the resource, preferring instead to present a dialog box describing the conflict to the user. Due to this scenario, a mechanism is needed to prevent different programs from accidentally ignoring locks taken out by other programs with the same authorization.

große männer große frauen In order to prevent these collisions a lock token MUST be submitted in the If header for all locked resources that a method may interact with or the method MUST fail. For example, if a resource is to be moved and both the source and destination are locked then two lock tokens must be submitted, one for the source and the other for the destination.

deutsche männer russische frauen Servers SHOULD restrict usage of the lock token to exactly the authenticated principal who created the lock.

singlebörse kärnten jobs In this example, even though both the source and destination are locked, only one lock token must be submitted, for the lock on the destination. This is because the source resource is not modified by a COPY, and hence unaffected by the write lock. In this example, user agent authentication has previously occurred via a mechanism outside the scope of the HTTP protocol, in the underlying transport layer.

was wollen männer von frauen im bett A successful MOVE request on a write locked resource MUST NOT move the write lock with the resource. However, the resource is subject to being added to an existing lock at the destination, as specified in frauen suchen männer mit geld. For example, if the MOVE makes the resource a child of a collection that is locked with "Depth: infinity", then the resource will be added to that collection's lock. Additionally, if a resource locked with "Depth: infinity" is moved to a destination that is within the scope of the same lock (e.g., within the namespace tree covered by the lock), the moved resource will again be a added to the lock. In both these examples, as specified in frauen suchen männer graz, an If header must be submitted containing a lock token for both the source and destination.

Note that there is a tradeoff in allowing non-owners of a lock to unlock a resource. It can be beneficial to allow non-lock owners to perform UNLOCK requests because it allows the adminstrator of the server to configure the server to grant longer lock timeouts because the administrator knows that there is a process in place to allow users to deal with forgotten locks left by other users. On the other hand, a disadvantage of unlocking someone else's lock is that can create a situation where two users are working on modifications to the same resource at the same time which can result in a client having to perform an merge that wasn't previously planned.die zeit partnersuche wien

free dating sites in johannesburg south africa When submitting a lock request a user agent may also submit an owner XML field giving contact information for the person taking out the lock (for those cases where a person, rather than a robot, is taking out the lock). This contact information is stored in a DAV:lockdiscovery property on the resource, and can be used by other collaborators to begin negotiation over access to the resource. However, in many cases this contact information can be very private, and should not be widely disseminated. Servers SHOULD limit read access to the DAV:lockdiscovery property as appropriate. Furthermore, user agents SHOULD provide control over whether contact information is sent at all, and if contact information is sent, control over exactly what information is sent.frauen suchen erfahrene männer

free dating websites for singles If a request would modify the content for a locked resource, a dead property of a locked resource, a live property that is defined to be lockable for a locked resource, or an internal member URI of a locked collection, the request MUST fail unless the lock-token for that lock is submitted in the request. An internal member URI of a collection is considered to be modified if it is added, removed, or identifies a different resource.

reiche frauen suchen männer österreich A successful request for an exclusive or shared write lock MUST result in the generation of a unique lock token associated with the requesting principal. Thus if five principals have a shared write lock on the same resource there will be five lock tokens, one for each principal. quoka.de partnersuche [online partnersuche österreich online: (redundant with other sections, deleted) --reschke]

singlebörse ohne premium mitgliedschaft jugendherberge While those without a write lock may not alter a property on a resource it is still possible for the values of live properties to change, even while locked, due to the requirements of their schemas. Only dead properties and live properties defined to respect locks are guaranteed not to change while write locked.

free dating sites in zambia free dating sites in new zealand

partnersuche frauen gratis A write lock on a collection, whether created by a "Depth: 0" or "Depth: infinity" lock request, prevents the addition or removal of member URIs of the collection by non-lock owners. As a consequence, when a principal issues a PUT or POST request to create a new resource under a URI which needs to be an internal member of a write locked collection to maintain HTTP namespace consistency, or issues a DELETE to remove an internal member URI of a write locked collection, this request MUST fail if the principal does not have a write lock on the collection.

gebildete frauen partnersuche However, if a write lock request is issued to a collection containing member URIs identifying resources that are currently locked in a manner which conflicts with the write lock, the request MUST fail with a 423 (Locked) status code (Note that this can only occur for a request of a "Depth: infinity" write lock).

partnersuche große frauen If a lock owner causes the URI of a resource to be added as an internal member URI of a "Depth: infinity" locked collection then the new resource MUST be automatically added to the lock. This is the only mechanism that allows a resource to be added to a write lock. Thus, for example, if the collection /a/b/ is write locked and the resource /c is moved to /a/b/c then resource /a/b/c will be added to the write lock.

free dating site in zurich free dating sites in zimbabwe

free dating sites in bay area If a user agent is not required to have knowledge about a lock when requesting an operation on a locked resource, the following scenario might occur. Program A, run by User A, takes out a write lock on a resource. Program B, also run by User A, has no knowledge of the lock taken out by Program A, yet performs a PUT to the locked resource. In this scenario, the PUT succeeds because locks are associated with a principal, not a program, and thus program B, because it is acting with principal A's credential, is allowed to perform the PUT. However, had program B known about the lock, it would not have overwritten the resource, preferring instead to present a dialog box describing the conflict to the user. Due to this scenario, a mechanism is needed to prevent different programs from accidentally ignoring locks taken out by other programs with the same authorization.

free dating sites in my area In order to prevent these collisions a lock token MUST be submitted in the If header for all locked resources that a method may interact with or the method MUST fail. For example, if a resource is to be moved and both the source and destination are locked then two lock tokens must be submitted, one for the source and the other for the destination.

singles ab 50 kostenlos ausdrucken Servers SHOULD restrict usage of the lock token to exactly the authenticated principal who created the lock.

This is because the source resource is not modified by a COPY, and hence unaffected by the write lock. In this example, user agent authentication has previously occurred via a mechanism outside the scope of the HTTP protocol, in the underlying transport layer.

free dating websites in egypt A COPY method invocation MUST NOT duplicate any write locks active on the source. However, as previously noted, if the COPY copies the resource into a collection that is locked with "Depth: infinity", then the resource will be added to the lock.

free online dating sites in egypt A successful MOVE request on a write locked resource MUST NOT move the write lock with the resource. However, the resource is subject to being added to an existing lock at the destination, as specified in free dating sites za. For example, if the MOVE makes the resource a child of a collection that is locked with "Depth: infinity", then the resource will be added to that collection's lock. Additionally, if a resource locked with "Depth: infinity" is moved to a destination that is within the scope of the same lock (e.g., within the namespace tree covered by the lock), the moved resource will again be a added to the lock. In both these examples, as specified in free dating site in gauteng, an If header must be submitted containing a lock token for both the source and destination.

A successful result MUST return a single lock token which represents all the resources that have been locked. If an UNLOCK is successfully executed on this token, all associated resources are unlocked. If the lock cannot be granted to all resources, a 207 (Multistatus) status code MUST be returned with a response entity body containing a multistatus XML element describing which resource(s) prevented the lock from being granted.

partnersuche rumänien frauen If the timeout expires then the lock may be lost. Specifically, if the server wishes to harvest the lock upon time-out, the server SHOULD act as if an UNLOCK method was executed by the server on the resource using the lock token of the timed-out lock, performed with its override authority. Thus logs should be updated with the disposition of the lock, notifications should be sent, etc., just as they would be for an UNLOCK request.

singlebörse kärnten kostenlos Servers are advised to pay close attention to the values submitted by clients, as they will be indicative of the type of activity the client intends to perform. For example, an applet running in a browser may need to lock a resource, but because of the instability of the environment within which the applet is running, the applet may be turned off without warning. As a result, the applet is likely to ask for a relatively small timeout value so that if the applet dies, the lock can be quickly harvested. However, a document management system is likely to ask for an extremely long timeout because its user may be planning on going off-line.

As noted in free dating sites in malaysia, there are several security risks associated with exposing a machine's IEEE 802 address. This section provides an alternate mechanism for generating the "node" field of a UUID which does not employ an IEEE 802 address. WebDAV servers MAY use this algorithm for creating the node field when generating UUIDs. The text in this section is originally from an Internet-Draft by Paul Leach and Rich Salz, who are noted here to properly attribute their work.free dating sites in mexico

männer suchen frauen kostenlos The ideal solution is to obtain a 47 bit cryptographic quality random number, and use it as the low 47 bits of the node ID, with the most significant bit of the first octet of the node ID set to 1. This bit is the unicast/multicast bit, which will never be set in IEEE 802 addresses obtained from network cards; hence, there can never be a conflict between UUIDs generated by machines with and without network cards.free dating sites in manila

partnersuche linz land führerscheinstelle If a system does not have a primitive to generate cryptographic quality random numbers, then in most systems there are usually a fairly large number of sources of randomness available from which one can be generated. Such sources are system specific, but often include:free dating sites in michigan

  • the percent of memory in use
  • the size of main memory in bytes
  • the amount of free main memory in bytes
  • the size of the paging or swap file in bytes
  • free bytes of paging or swap file
  • the total size of user virtual address space in bytes
  • the total available user address space bytes
  • the size of boot disk drive in bytes
  • the free disk space on boot drive in bytes
  • the current time
  • the amount of time since the system booted
  • the individual sizes of files in various system directories
  • the creation, last read, and modification times of files in various system directories
  • the utilization factors of various system resources (heap, etc.)
  • current mouse cursor position
  • current caret position
  • current number of running processes, threads
  • handles or IDs of the desktop window and the active window
  • the value of stack pointer of the caller
  • the process and thread ID of caller
  • various processor architecture specific performance counters (instructions executed, cache misses, TLB misses)

singlebörse ohne premium mitgliedschaft parship In addition, items such as the computer's name and the name of the operating system, while not strictly speaking random, will help differentiate the results from those obtained by other systems.free dating sites in manchester

100 free dating site in czech republic The exact algorithm to generate a node ID using these data is system specific, because both the data available and the functions to obtain them are often very system specific. However, assuming that one can concatenate all the values from the randomness sources into a buffer, and that a cryptographic hash function such as MD5 is available, then any 6 bytes of the MD5 hash of the buffer, with the multicast bit (the high bit of the first byte) set will be an appropriately random node ID.free dating sites in minneapolis

partnersuche griechenland kostenlos Other hash functions, such as SHA-1, can also be used. The only requirement is that the result be suitably random in the sense that the outputs from a set uniformly distributed inputs are themselves uniformly distributed, and that a single bit change in the input can be expected to cause half of the output bits to change.free dating sites in miami
