fix#2254: if the DB was closed without calling stop_io() and then an interrupt arrives (e.g. incoming message), the db was corrupted.
* Add result.log() for logging with less boilerplate code
* Bugfix: Resultify housekeeping() to make it abort if the db is closed instead of just deleting everything
* Require the UI to call dc_stop_io() before backup export
* Prepare a bit better for closed-db: Resultify get_uidvalidity and get_uid_next and let job::load_next() wait until the db is open
About the bug (before this PR):
if the DB was closed without calling stop_io() and then an interrupt arrives (e.g. incoming message):
- I don't know if it downloads the message, but of course at some point the process of receiving the message will fail
- In my test, DC is just in the process of moving a message when the imex starts, but then can't delete the job or update the msg server_uid
- Then, when job::load_next() is called, no job can be loaded. That's why it calls `load_housekeeping_job()`. As `load_housekeeping_job()` can't load the time of the last housekeeping, it assumes we never ran housekeeping and returns a new Housekeeping job, which is immediately executed.
- housekeeping can't find any blobs referenced in the db and therefore deletes almost all blobs.
* deprecate mostly unused dc_get_blocked_cnt() api
instead, the size returned by get_blocked_contacts() should be checked,
this is safer and allows easier adaption of blocking rules.
ui or python seems not to use dc_get_blocked_cnt(),
however, there is one test in node,
therefore, the function will continue working for now
(by just returning Contact::get_all_blocked().len() then)
* add decision api to repl tool
* add block/unblock api to repl tool
* unify usage of @deprecated doxygen command
* draft dc_msg_set_html() api
* implement setting 'html to be send'
* test sending html-parts
* more flexible html-partbuilder
* write html-parts to database and also send them
* add 'sendhtml' command to repl tool
This removes the proxy via crate::error to depend on anyhow directly.
There is no benefit to this indirection and this makes it simpler to
see which error types are used.
* add failing tests for forwarding html-mails
* let MsgId.get_html() return an option
* write html-part to local database on forwarding
* add html-part to forwarded non-dc messages
* read HTML-parts from encrypted messages
* avoid clone()
* Received:-header is no longer needed since #2152
* Update src/html.rs

* draft API to deal with uncut message texts
* add column mime_modified
* add mime_modified flag to MimeParser and save it in the database
* save mime_headers also when mime_modified is set
* cargo fmt
* set mime_modified on parsed html-texts and when there are multiple alternative-parts; add test for that
* prototype functions, add to repl and ffi
* use correct mime_modified flag
* basically parse Mime-Structure to HTML
* add basic tests for HTML-parsing
* convert text/plain to html for getting original
* respect charset for plain texts
* make test more specific
* fix handling non-utf-8 charsets for plain messages
* add test for plain_to_html()
* add failing test for plaintext linkify
* linkify urls in plain text
* fix regex
* plain text linkify: add failing test for encapsulated links as <https://domain.com>
* plain text linkify: make encapsulated links as <https://domain.com> work
* plain text linkify: require word boundary at beginning of link, add tests for that
* plain text linkify: linkify emails
* plain text: support format=flowed
* plain text: support quotes
* make clippy happy
* set mime-modified also when simplify() cuts non-html messages, add tests for that
* streamline mime recursion
* repl tool: write original html to file for further processing
* convert cid:- to data:-protocol
* add a test for cid: to data: conversion
* make clippy happy
* fix html-tests to work with windows-lineends
* clarify what the returned html-code may contain
* add some more detailed doc comments
* add mime_modified column only if not exist
this additional check is needed
as the column may added with another dbversion in
some shipped beta-versions.
* incorporate documentation suggestions from review
* rename get_original_mime_html() to more simple get_html()
* rename api is_mime_modified() to more simple has_html(); internally, mime_modified-flag stays as-is, however
* rename MimeS to MimeMultipartType
* do not set mime-modified flag for encrypted messages that need extra-handling for saved mime-structure
* fix typo
* move get_msg_html() to MsgId.get_html()
* incorporate more documentation suggestions from review
* remove unused return value from collect_texts_recursive()
* avoid mime_modified being mutable in write-parts-loop
* move 'use futures::future::FutureExt' atop of html.rs
* move attributes defining plain-text to a dedicated structure
* more PlainText to separate file
* escape cid when building regex
* let dc_get_msg_html() return NULL when calling with bad param
Previously MX records were queried only for OAuth 2 configuration and
did not affect the list of servers tried. User was required to manually
configure the servers for Google Workspace (former GSuite) domains.
Now MX records are queried during configuration. If provider is found in
offline database, its ID, corresponding to the filename, is saved as
`configured_provider`.
`configured_provider` is also set during database migration if email
address uses the domain from the provider database, but no MX querying
is done.
update_device_chats() takes about 2 seconds on a modern device (Android) because the
welcome image file has to be written to the disk as a blob. The problem
was that this was done after the progress bar had vanished and before
anything else happened so that I thought that something had gone wrong
multiple times.
The UIs have to remove update_device_chats(), too..
both are not used in productive:
- chat-id "in-creation" was dropped completely already in core-c
as it does not allow assigning messages to chats in time.
- message flag "starred" was added at some point and never used.
ux-wise, "disappearing messages" promises to clean up a chat -
this does not fit well with "starring" messages.
"saved messages" chat seems to be superior in that regard.
but anyway, it is not used but comes at maintainance costs,
so it is better to delete its functionality for now.
(the db entries, however, are left for now,
that might be more tricky to remove)
'Delete emails from server' was an experimental ad-hoc function
that was added before 'Automatically delete old messages' was introduced
to allow at least some way to cleanup.
'Delete emails from server'-UI was already removed from android/ios in june
(see https://github.com/deltachat/deltachat-android/pull/1406)
and the function never exists on desktop at all.
