Such an URL would be, for instance: - -pop3://po.myisp.com:1 - -Meaning: "Access message 1 on Pop3 server po.myisp.com" - - -However, referencing a message with its number within a folder is a -very unreliable method: - -1) Message order in a folder can change during a session: - - The user can move or remove messages from the folder, thus - completely changing message numbers. We could however imagine to - follow message operations in order to keep camel in a coherent - state at each time instant. This could be quite complex but may - be feasible using gtk signal system. - -2) Message order can change between sessions: - - Gnome-mailer was designed from the begining to allow messages to be - stored in classical mailboxes (mbox, maildir, MH, IMAP ...), in - order to allow users to run other MUA on their mailboxes if - necessary. These other MUA can change message order within folders - without any chance for Camel to trace the operations. - -These two scenarii show that it is quite impossible to use reliable -folder caching or message referencing if messages are referenced only -by their position within their parent folder. - - -We thus have to find a general way to identify and retreive a message -within its folder. One thing is sure, however: all folders -implementation won't allow this method. Pop3 stores will always access -messages using their rank on the server. MUA using Camel will thus -have to be prepared to access some stores providing only the old -fashionned message number access method. - -Basically, we have two choices: - -1) Accessing messages using (mailbox) Unique ID (UID) - - A UID is a string identifier associated to a message, which is - guaranteed to be unique within its parent folder and which will not - change between sessions. - -2) Accessing messages using Message ID - - A Message ID is a string identifier associated to a messages which - is guaranteed to be unique in the world, that is, no other message - can have the same Message ID. The message ID is defined in RFC 822, - and is stored as the message header "Message-id" - -Method (1) already exists in IMAP. -It is quite simple to define on local stores (MH, mbox, ....) but it -may not resist to message modification by other MUA. -Methods based on Message-id matching or message content checksum seem -to be the best one. Using an "X-" header is another possibility for -non read-only folders. A combination of these three methods may be the -most reliable solution. -The UID is impossible to implement in a POP3 store provider. - -(2) Can be used with IMAP, but would be very ineficient. -The main issue with this method is its dependancy upon other MUAs and -MTAs. Message-id is set before or during message transport. Moreover, -some rfc822 compliant messages may not even have any Message-id -header. -These are major issues when accessing read-only stores. -The M-ID is also impossible to implement in a POP3 store provider. - - -We may not rely on external MUA and MTA to guarentee the uniqueness of -the identifier . We may loose messages by never being able to read them -if two had the same uid. It would be possible to find workarounds, but -it could make Camel use a bit tricky. - -Given that most users will use IMAP or a database based store as their -main mail store, and given that this stores allow UID very -easily, I suggest that we use method (1). Discussion is still open, -though. - -Here are the public methods I propose to add to CamelFolder: - -gboolean camel_folder_supports_uid (CamelFolder *folder) - returns true if the folder can get messages - by their uid. - -gchar * camel_folder_get_uid_by_number (CamelFolder *folder, gint message_number) - return the uid of message which number in the folder - is %message_number. - -gchar * camel_folder_get_message_uid (CamelFolder *folder, CamelMimeMessage *message) - return the uid of the message within the folder. - -CamelMimeMessage *camel_folder_get_message_by_uid (CamelFolder *folder, gchar *uid) - return the message which uid is %uid - -In addition, the CamelMessage Class will have a new public method - -gchar * camel_mime_message_get_uid (CamelMimeMessage *message) - return the uid associated to the message in its physical parent - folder. - - - -B) Handling message references in (v)folders. ---------------------------------------------- - - -We want the future Gnome mailer to be able to build (virtual) folders -holding references to messages physically located in other -folders. More generally, we would like folders to be able to hold: - -1) messages -2) subfolders -3) references to messages - -(1) and (2) are already implemented in Camel because most mail stores -can hold messages and/or subfolders. - -(3) is a different issue, because no existing mail store can currently -hold, within folders, references to messages in other folders. -It will thus be a specific gnome-mailer extension. - - -One of the main issue is to determine what kind of behaviour we expect -from folders holding references. Here is a possible API. - -( the world (v)folder is used to distinguish between the physical -parent folder and the folder holding a reference to the message, when -a confusion may arise) - -Addition to CamelFolder: - -gboolean camel_folder_can_hold_references (CamelFolder *folder) - return true if the folder can contain references - -void camel_folder_add_reference_by_uid (CamelFolder *folder, gchar *folder_url, gchar *message_uid) - add a reference into a folder. %folder_url is the url of - the folder, %message_uid is the uid of the message within - its physical parent folder. - -void camel_folder_add_reference_by_message (CamelFolder *folder, CamelMessage *message) - add a reference. The place where the reference points - to is found using CamelMessage methods - -void camel_folder_remove_reference_by_uid (CamelFolder *folder, gchar *uid) - remove a message reference form a folder. Reference - is identified using its uid within the folder. - -gboolean camel_folder_uid_is_reference (CamelFolder *folder, gchar *uid) - return true if the message corresponding to the uid is a reference. - -Then all usual operations on the folder act if the message was -actually physically stored in this folder. For example, when the mailer -uses camel_folder_get_message_by_uid onto the (v)folder, the actual -message is retreived from its physical store. - -As you can see, the uid of the message within its physical parent -folder is different than its uid within the (v)folder. This is because -there is no way to guarantee that the uids of two messages in two -different folders would be different. Using references on this two -message in the same vfolder would break uniqueness of the uid in the -(v)folder. - -A couple of other methods could be defined but all the basics are -described here. - -This draft API is far from complete nor perfect, and is described here -only to stimulate discussions before the actual implementation. - - -The question now is to know how we store references. There are basically -two ways: - -1) references are stored using the URL of the physical folder - and the uid of the message within the folder - -2) a list of reference is kept, and in this list, reference are stored -as in (1). Folders would refer to the actual message using index in -the list - - - -The main problem with (1) is that references get lost as soon -as the actual message is moved. There is no way to find in which -folders references to the message exist. - -(2) is a way to solve this issue. When messages are used, Camel looks -in the list to see if the message is refered somewhere, and actualize -the URL and the uid with their new values. - -The problem with (2) is that we need to keep this information in a file -and libraries writing automatically to files are generally a bad idea. - -As in additional remark, it is clear that Camel will only be able to -hold references to messages on stores supporting UIDs. - - -Thanks in advance for your comments and ideas, - - - Bertrand <Bertrand.Guiheneuf@aful.org> - - --- - -[1] : http://www.selequa.com/%7epurp/gnomail/mail2db.html -[2] : http://www.selequa.com/%7epurp/gnomail/dbRecFmt.html -[3] : http://www.gnome.org/mailing-lists/archives/gnome-mailer-list/1999-April/0248.shtml diff --git a/devel-docs/query/virtual-folder-in-depth.sgml b/devel-docs/query/virtual-folder-in-depth.sgml deleted file mode 100644 index d3e3e0504b..0000000000 --- a/devel-docs/query/virtual-folder-in-depth.sgml +++ /dev/null @@ -1,407 +0,0 @@ -<!doctype article PUBLIC "-//Davenport//DTD DocBook V3.0//EN" []> - -<!-- SGMLized by Bertrand <Bertrand.Guiheneuf@aful.org> --> - -<article id="index"> - <artheader> - <authorgroup> - <author> - <firstname>Giao</firstname> - <surname>Nguyen</surname> - </author> - </authorgroup> - - <title>An in-depth look at the virtual folder mechanism</title> - <abstract> - <para> - This document describes a different way of approaching mail - organization and how all things are possible in this brave new - world.

Any matches are added to the -resulting vfolder. - -* Summary files - -Summary files are only meaningful when applied to the context of the -default-vfolder of a store. - -Summary files should be generated for queries of the form: - -(function "constant value") - -Summary files should never be generated for queries of the form: - -(function (function1)) - -(and (function "value") - (another-function "another value")) - -Given a query of the form: - -(and (function "value") - (another-function "another value")) - -The system should use one summary file for (function "value") and -another summary file for (another-function "another value"). I will -call the prior form the "plain form". - -It should be noted that the signature of the store should be based on -the assumption that new data may have been added to the store since -the application generated the summary file. Signatures generated on -the entirety of the store will most likely be meaningless for things -like POP/IMAP servers. - -* Incremental indexing - -When new messages are detected, all known queries should be evaluated -on the new messages. vfolders should be notified of new messages that -are positive matches for their queries. The indexes generated by this -process should be merged into the current indexes for the vfolder. - -* Can I have multiple stores? - -I don't see why not. Again, the inbox is a vfolder so you can get a -unified inbox consisting of all new mail sent to all your stores or -your can get inboxes for each store or any combination your heart -desire. You get your cake, eat it, and someone else cleans the dishes! - -* Why all this? - -Consider the dynamic nature of the following query: - -(and (author "Giao") - (sent-after (today-midnight))) - -today-midnight would be a function that is evaluated at run-time to -calculate the appropriate object. - -* Scenarios of usage and their solutions - -** Mesage alterations - -This is a fuzzy area that should be left to the UI to handle. Messages -are altered. Read status are altered when a new message is read for -example. How do we handle this if our query is for unread messages? -Upon viewing the state would change. - -One idea is to not evaluate the queries unless we're changing between -vfolder views. This assumes that one can only view a particular -vfolder at a time. For multi-vfolder viewing, a message change should -propagate through the vfolder system. Certain effects (as in our -example) would not be intuitive. - -It would not be a clean solution to make special cases but they may be -necessary where certain defined fields are ignored when they are -changed. Some combination of the above rules can be used. I don't -think it's an easy solution. - -** Message inclusion and exclusion - -Messages are included and excluded also with queries. The final query -will have the form of: - -(and (author "Giao") - (criteria value) - (not (criteria other-value))) - -Userland criterias may be a label of some sort. These may be userland -labels or Message-IDs. What are the performance issues involved in -this? With short circuiting, it's not a major problem. - -The criterias and values are determined by the UI. The vfolder -mechanism isn't concerned with such issues. - -Messages can be included and excluded at will. The idea is often -called "arbitrary inclusion/exclusion". This can be done by -Message-IDs or other fields. It's been noted that Message-IDs are not -unique. - -I propose that any given vfolder is allocated an inclusion label and an -exclusion label. These should be randomly generated. This should be -part of the vfolder description. It should be noted that the vfolder -description has not been drafted yet. - -The result is such that the rules for a given named query is: - -(and (user-query) - (label inclusion-label) - (not exclusion-label)) - -** Query scheduling - -Consider the following extremely dynamic queries: - -A: -(and (author "Giao") - (sent-after (today-midnight))) - -B: -(and (sent-after (today-midnight)) - (author "Giao")) - -C: -(or (author "Giao") - (sent-after (today-midnight))) - -Query A would be significantly faster because (author "Giao") is not -dynamic. A summary file could be generated for this query. Query B is -slow and can be optimized if there was a query compiler of some -sort. Query C demonstrates a query in which there is no good -optimization which can be applied. These come with a certain amount of -baggage. - -It seems then that for boolean 'and' operations, plain forms should be -moved forward and other queries should be moved such that they are -evaluated later. I would expect that the majority of queries would be -of the plain form. - -First is that the summary file is tied to the query and the store -where the query originates from. Second, a hashing function for -strings needs to be calculated for the query so that the query and the -summary file can be associated. This hashing function could be similar -to the hashing function described in Rob Pike's "The Practice of -Programming". (FIXME: Stick page number here) - -** Archives - -Many people are concerned that archives won't be preserved, archives -aren't supported, and many other archive related issues. This is the -short version. - -Archives are just that, archives. Archives are stores. Take your -vfolder, export it to a store. You are done. If you load up the store -again, then the default-vfolder of that store is the view of the -vfolder, except the query is different. - -The point to vfolder is not to do away with classical folder -representation but to move the queries to the front where it would -make data management easier for people who don't think in terms of -files but in terms of queries because ordinary people don't think in -terms of files. - -* Miscellany - -** Annotations - -There should be a scheme to add annotations to messages. Common mail -user agents have used a tag in the message header to mark messages as -read/unread for example. Extending on this we have the ability to add -our own data to a message to add meaning to it. If we have a good -scheme for doing this, new possibilities are opened. - -*** Keywords - -When sending a message, a message could have certain keywords attached -to it. While this can be done with the subject line, the subject line -has a tendency to be munged by other mail applications. One popular -example is the "[rR]e:" prefix. Using the subject line also breaks the -"contract" with other mail user agents. Using keywords in another -field in the message header allows the sender to assist the recipient -in organizing data automatically. Note that the sender can only -provide hints as the sender is unlikely to know the organization -schemes of the recipient. - -** Scope - -Let us assume that we have multiple stores. Does a query work on a -given store? Or does it work on all stores? Or is it configurable such -that a query can work on a user-selected list of stores? - -* Alternatives to the above - -Jim Meyer <purp@selequa.com> is putting some notes on where -annotations needs to be located. They'll be located here as well as -any contributions I may have to them. |
