Android allows other apps to access protected content of an app without requesting the
necessary permission when the app returns an Intent with FLAG_GRANT_READ_URI_PERMISSION.
This regularly happens as a result of ACTION_GET_CONTENT, i.e. what we use to pick content
to be attached to a message. Accessing that content only works while the receiving activity
is running. Afterwards accessing the content throws a SecurityException because of the
missing permission.
This commit changes K-9 Mail's behavior to copy the content to a temporary file in K-9's
cache directory while the activity is still running.
Fixes issue 4847, 5821
This also fixes bugs related to the fact that K-9 Mail didn't save a copy of attached content
in the message database.
Fixes issue 1187, 3330, 4930
In addition to a couple of custom ROMs linking /dev/urandom to a non-writable
*random version, now Samsung's SELinux policy also prevents apps from opening
/dev/urandom for writing. Since we shouldn't need to write to /dev/urandom anyway
we now simply don't.
Don't convert the content-type to lower case in
MimeMessage.getContentType. The content-type may have optional parameters
that are case sensitive (boundary, name).
In removing the lower-case conversion from getContentType, a review was
made for inappropriate case-sensitive comparisons which use data obtained
with getContentType. The only ones found were in isMimeType in both
Message and MimeBodyPart.
Case-sensitive instances of isMimeType were made case-insensitive. Also,
isMimeType was moved from Message to MimeMessage for symmetry with
MimeBodyPart (MimeMessage & MimeBodyPart are similar and contain a good
bit of duplication such as this).
The unit test required fixing now that the case of the boundary text is
preserved.
References:
Commits 2c5186 and dc4002 added the toLowerCase to getContentType in
MimeMessage & MimeBodyPart (Issue 94).
Later, commit 50cd60 removed the toLowerCase addition from MimeBodyPart
(Issue 1289).
Fix the unit test to match.
All line endings in the unit test are now the same.
(Just for consistency. Not a big deal, since such problems are fixed when
the messages are run through EOLConvertingOutputStream.)
The preceding commit resulted in attachments of type message/rfc822 being
sent with 8bit encoding even when the SMTP server did not support
8BITMIME. This commit assures that messages will be converted to 7bit
when necessary.
A new interface CompositeBody was created that extends Body, and classes
Message and Multipart were changed from implementing Body to
CompositeBody. Additional classes BinaryTempFileMessageBody and
LocalAttachmentMessageBody were created (by extending BinaryTempFileBody
and LocalAttachmentBody, respectively), and they too implement
CompositeBody.
A CompositeBody is a Body containing a composite-type that can contain
subparts that may require recursive processing when converting from 8bit
to 7bit. The Part to which a CompositeBody belongs is only permitted to
use 8bit or 7bit encoding for the CompositeBody.
Previously, a Message was created so that it was 7bit clean by default
(even though that meant base64 encoding all attachments, including
messages). Then, if the SMTP server supported 8BITMIME,
Message.setEncoding("8bit") was called so that bodies of type TextBody
would been transmitted using 8bit encoding rather than quoted-printable.
Now, messages are created with 8bit encoding by default. Then, if the
SMTP server does not support 8BITMIME, Message.setUsing7bitTransport is
called to recursively convert the message and its subparts to 7bit. The
method setUsing7bitTransport was added to the interfaces Part and
CompositeBody.
setEncoding no longer iterates over parts in Multipart. That task belongs
to setUsing7bitTransport, which may in turn call setEncoding on the parts.
MimeUtility.getEncodingforType was created as a helper function for
choosing a default encoding that should be used for a given MIME type when
an attachment is added to a message (either while composing or when
retrieving from LocalStore).
setEncoding was implemented in MimeBodyPart to assure that the encoding
set in the Part's headers was the same as set for the Part's Body. (The
method already existed in MimeMessage, which has similarities with
MimeBodyPart.)
MimeMessage.parse(InputStream in, boolean recurse) was implemented so that
the parser could be told to recursively process nested messages read from
the InputStream, thus giving access to all subparts at any level that may
need to be converted from 8bit to 7bit.
The problem: Receive a message with an attachment of type message/rfc822
and forward it. When the message is sent, K-9 Mail uses base64 encoding
for the attachment. (Alternatively, you could compose a new message and
add such an attachment from a file using a filing-picking app, but that is
not 100% effective because the app may not choose the correct
message/rfc822 MIME type for the attachment.)
Such encoding is prohibited per RFC 2046 (5.2.1) and RFC 2045 (6.4). Only
8bit or 7bit encoding is permitted for attachments of type message/rfc822.
Thunderbird refuses to decode such attachments. All that is shown is the
base64 encoded body.
This commit implements LocalAttachmentBody.setEncoding. If an attachment
to a newly composed message is itself a message, then setEncoding("8bit")
is called, otherwise setEncoding("base64") is called for the attachment.
Similar behavior occurs when an attachment is retrieved from LocalStore.
The setEncoding method was added to the Body interface, since all
implementations of Body now declare the method.
The problem here differs from that in the preceding commit: Here, the
encoding problem occurs on sending, not on receipt. Here, the entire
message (headers and body) is base64 encoded, not just the body. Here,
the headers correctly identify the encoding used; it's just that the RFC
does not permit such encoding of attached messages. The problem here
could in fact occur in combination with the preceding problem.
Issue 5734 exemplifies the problem: receive a message with an attachment
of type message/rfc822 that doesn't use base64 encoding for the body of
the attached message. K-9 Mail incorrectly stores the attached message
locally with its original headers but using base64 encoding for the body.
A discrepancy thus exists between what the headers say about the encoding
of the body versus the actual encoding used. This is obvious when
attempting to view the attachment (either by using a compatible message
viewer available on the device or by saving the attachment to a file and
viewing the file contents).
The process: When a message with an attached sub-message is received,
Message.parse puts the attachment in a new MimeMessage with the
attachment's body in a BinaryTempFileBody. LocalFolder.saveAttachment
then calls Message.writeTo (which later calls BinaryTempFileBody.writeTo)
to place the entire attachment (headers and body) in a new file that will
become a LocalAttachmentBody. Until now, BinaryTempFileBody.writeTo
could only save the message body using base64 encoding.
This commit implements BinaryTempFileBody.setEncoding and assures that the
body is written out with the same encoding that was found in its headers.
Currently, K-9 Mail detects if an SMTP server supports 8BITMIME (RFC
6152), and if so, TextBody parts are sent with content-transfer-ecoding =
8bit. Otherwise, they are sent using quoted-printable.
This adds the required "BODY=8BITMIME" parameter to the MAIL command when
sending messages to servers that support 8BITMIME.
The new method is a little bit janky, but a little bit of jank is better than 2n
heavy SQL count queries per folder before we even show the folder list.
On my 200 folder account, display of the folder list activity drops from 10+s to

If you attempted to use SSL to connect to a server that speaks
STARTTLS, you should get an SSL protocol error. Instead, you
were likely to get an "Unrecognized Certificate" error that shows
you an unrelated certificate chain and asks you to accept it or
reject it. Neither action would work because the actual problem
had nothing to do with certificates. The unrelated certificate
chain that popped up had been statically stored when validating
a prior connection to a different server.
With this patch, certificate chains are no longer stored statically
when validating server connections.
Issue 5886 is an example of a user experiencing this problem.
Deleting a message creates an entry in EmailProviderCache so
EmailProviderCacheCursor can skip the Cursor row during the time
it takes to update the database.
Previously EmailProviderCacheCursor.isLast() returned the wrong
result when the last row in the wrapped Cursor was hidden. This
lead to the crash in MergeCursor.
Fixes issue 5820
Effective with earlier commit e2c5229e85,
messages are wrapped with <html> tags at display time, rather than
when messages are saved.
For consistency, this commit removes tags from a status message, because
they, too, will be added back at display time.

This patch makes sure actions started via the context menu operate on
the correct message even when the message list changes and the 'adapter
position' accessible via the menu object points to another message.
When the message the menu was opened for is deleted the context menu
will be closed.
Previously the app crashed when upgrading the database failed. Now we
reset the database version and run the upgrade code again (recreating
all tables).

This reverts commit bbdec62e37.
Aside from being the incorrect solution for fixing the problem
described in pull request 211, the patch generates 'Dead code'
warnings inside the if(){} statements on lines 46 and 47.
The correct fix for the problem was already implemented in commit
5678786c97.
Although the logcat in the pull request was generated after the fix,
line numbers in the log indicate that it was based on an outdated
version of MimeUtility.java from before the fix.

Previously the activity theme was used to display the auto-complete
suggestions. This lead to unreadable text when the activity theme was
different from the "composer theme".
This was disabled in faa666394c
because it isn't possible to extract the name of the android
contact in the 'ORDER BY...' clause when querying the database.
Instead it simply sorts by the email address.
This may cause the same contact to appear multiple times in
the list, if they have multiple email addresses assigned.
But in most cases this is good enough and surely better than
not having the option to sort by sender at all.
Desktop mail clients such as Thunderbird also simply use the
sender email information when sorting the column.
This also adds a SenderComparator for usage in the MergeCursor.
Seemingly the intents in the task back stack got confused when the
pending intent was updated in those versions (the Accounts intent was
delivered to MessageList). Avoid that by not updating the current
intent, but dropping the old one.
Fixes issue #4955.
Previously messages in the local Trash folder were marked as deleted,
then deleted from the server. During the next sync the placeholders for
deleted messages are removed from the database.
Obviously this doesn't work for POP3 accounts because the Trash folder
can't be synchronized with the server. So, for POP3, we now immediately
clear out all messages in that folder.
The server search itself does work. But the results are not displayed
to the user because only the message headers of found messages are
downloaded and the subsequent search in the local database won't return
those messages.
This requires another database schema change. With this change messages
at the root of a thread reference themselves in the 'threads' table,
i.e. 'root' contains the value of 'id' for these messages. It makes
selecting all messages in a thread much simpler.
Dynamically generate the CSS style for <pre> elements
for inclusion in the HTML <head> element when messages
are displayed.
This permits a user to change their font-family preference
for plain text messages and see the results immediately.
Obviously any old locally-stored messages that had their
font-family stored with them will continue to display using
that font-family, irrespective of the user's current
preference setting.
The MIME type for the supplied text was always text/html,
so there is no need to pass that as a parameter.
Furthermore, we are relying on it being text/html because
we are wrapping it with HTML code.
Likewise, change/simplify/rename AccessibleWebView.loadDataWithBaseURL().
Previously, <html>, <head>, & <body> tags were
attached to messages before they were stored locally.
But now that the <head> element also needs to include
a <meta> element (for proper MessageWebView display),
it seems unecesary to store all these tags with each
message.
Now the tags are no longer stored with the messages. Instead,
MessageWebView applies the tags before displaying the message.
This also eliminates the need to upgrade an older
message database where all the old messages would have
otherwise needed to be wrapped with the new tags.
Now that MessageWebView has 'setUseWideViewPort(true)',
the wide view port is excessively wide. It turns out
Android is using a fixed width of 980 px, so that even
plain text messages (which are already wrapped to fit
the screen) have a large empty area beside them when
scrolled to the left.
Injecting a meta tag in the html header fixes the
problem.
Database updates can be surprisingly slow. This lead to slow updates of
the user interface which in turn made working with K-9 Mail not as fun
as it should be. This commit hopefully changes that.
This happened for example in a starred-message-only view when
un-starting the last message. This led to isFirst() and isLast()
causing a NullPointerException when trying to update the
previous / next buttons.
- Android does not support ellipsize in combination with maxlines
for TextViews. This caused getEllipsisCount() in MessageTitleView
to always fail, and the full subject was never shown in the regular
headers area when needed.
To work around that, check for ourselves whether the text is
longer than 2, and ellipsize manually.
- Clicking the star button on a message caused the subject line to
re-appear, even if it fits in the action bar title without being
cut off. This was caused by MessageHeader.populate(), which always
set the subject to visible.
As a workaround: Only set subject to visible in case populate()
actually shows a new message.
- delete res/layout/actionbar_message_view.xml, its already present
in the actionbar_custom.xml
This fixes the following scenario:
- Get a mail notification
- Click on notification -> message view appears
- Press home
- Get a new notification
- Click on notification -> last instead of new message is displayed
This way also the From: selection, To:, Cc, and Bcc: are themed correctly.
It looks more homogeneous and is consistent with the looks of the MessageView.
by default.
The message view theme isn't something the user is likely to change on a
regular basis, so we don't need to clutter the message view menu with
this setting. The menu item can still be enabled for those who want it.
