notmuch_message_tags_to_maildir_flags: Do nothing outside of "new" and "cur"

2010-11-11T22:32:17Z

Some people use notmuch with non-maildir files, (for example, email messages in MH format, or else cool things like using sluk[*] to suck down feeds into a format that notmuch can index). To better support uses like that, don't do any renaming for files that are not in a directory named either "new" or "cur". [*] https://github.com/krl/sluk/

lib: Add new, public notmuch_message_get_filenames

2010-11-11T11:40:19Z

This augments the existing notmuch_message_get_filename by allowing the caller access to all filenames in the case of multiple files for a single message. To support this, we split the iterator (notmuch_filenames_t) away from the list storage (notmuch_filename_list_t) where previously these were a single object (notmuch_filenames_t). Then, whenever the user asks for a file or filename, the message object lazily creates a complete notmuch_filename_list_t and then: For notmuch_message_get_filename, returns the first filename in the list. For notmuch_message_get_filenames, creates and returns a new iterator for the filename list.

lib: Add new implementation of notmuch_filenames_t

2010-11-11T11:40:19Z

The new implementation is simply a talloc-based list of strings. The former support (a list of database terms with a common prefix) is implemented by simply pre-iterating over the terms and populating the list. This should provide no performance disadvantage as callers of thigns like notmuch_directory_get_child_files are very likely to always iterate over all filenames anyway. This new implementation of notmuch_filenames_t is in preparation for adding API to query all of the filenames for a single message.

lib: Rework interface for maildir_flags synchronization

2010-11-11T11:40:19Z

Instead of having an API for setting a library-wide flag for synchronization (notmuch_database_set_maildir_sync) we instead implement maildir synchronization with two new library functions: notmuch_message_maildir_flags_to_tags and notmuch_message_tags_to_maildir_flags These functions are nicely documented here, (though the implementation does not quite match the documentation yet---as plainly evidenced by the current results of the test suite).

Maildir synchronization

2010-11-10T21:09:31Z

This patch allows bi-directional synchronization between maildir flags and certain tags. The flag-to-tag mapping is defined by flag2tag array. The synchronization works this way: 1) Whenever notmuch new is executed, the following happens: o New messages are tagged with configured new_tags. o For new or renamed messages with maildir info present in the file name, the tags defined in flag2tag are either added or removed depending on the flags from the file name. 2) Whenever notmuch tag (or notmuch restore) is executed, a new set of flags based on the tags is constructed for every message and a new file name is prepared based on the old file name but with the new flags. If the flags differs and the old message was in 'new' directory then this is replaced with 'cur' in the new file name. If the new and old file names differ, the file is renamed and notmuch database is updated accordingly. The rename happens before the database is updated. In case of crash between rename and database update, the next run of notmuch new brings the database in sync with the mail store again.

lib: Add GCC visibility(hidden) pragmas to private header files.

2010-11-02T05:35:48Z

This prevents any of the private functions from being leaked out through the library interface (at least when compiling with a recent-enough gcc to support the visibility pragma).

Add support (and tests) for messages with really long message IDs.

2010-06-04T20:35:07Z

Scott Henson reported an internal error that occurred when he tried to add a message that referenced another message with a message ID well over 300 characters in length. The bug here was running into a Xapian limit for the length of metadata key names, (which is even more restrictive than the Xapian limit for the length of terms). We fix this by noticing long message ID values and instead using a message ID of the form "notmuch-sha1-". That is, we use SHA1 to generate a compressed, (but still unique), version of the message ID. We add support to the test suite to exercise this fix. The tests add a message referencing the long message ID, then add the message with the long message ID, then finally add another message referencing the long ID. Each of these tests exercise different code paths where the special handling is implemented. A final test ensures that all three messages are stitched together into a single thread---guaranteeing that the three code paths all act consistently.

Avoid database corruption by not adding partially-constructed mail documents.

2010-06-04T17:16:53Z

Previously we were using Xapian's add_document to allocate document ID values for notmuch_message_t objects. This had the drawback of adding a partially constructed mail document to the database. If notmuch was subsequently interrupted before fully populating this document, then later runs would be quite confused when seeing the partial documents. There are reports from the wild of people hitting internal errors of the form "Message ... has no thread ID" for example, (which is currently an unrecoverable error). We fix this by manually allocating document IDs without adding documents. With this change, we never call Xapian's add_document method, but only replace_document with either the current document ID of a message or a new one that we have allocated.

Make Received: header special in notmuch_message_file_get_header

2010-04-26T21:44:06Z

With this patch the Received: header becomes special in the way we treat headers - this is the only header for which we concatenate all the instances we find (instead of just returning the first one). This will be used in the From guessing code for replies as we need to be able to walk ALL of the Received: headers in a message to have a good chance to guess which mailbox this email was delivered to.
