When message viewing and tap the next icon, menu icons (previous, next, delete and replys) disappears for an instant.
But a compose icon remains, then tap it accidentally.
Also, include the sent-date in the header when using
the "prefix" quote style. "Be like mutt" (and gmail,

Also, the quoteOriginalHtmlMessage method was using the mSourceMessage
field in various places when it should be using its originalMessage
parameter.

Instead, have K9.onCreate initialize the location of the key
store file (similar to what is done with
BinaryTempFileBody.setTempDirectory).
Also, LocalKeyStore.getInstance has been changed so that it
no longer needs to be synchronized.
The classes are just as much related to com.fsck.k9.mail.transport
as com.fsck.k9.mail.store, so having them in
com.fsck.k9.mail.store doesn't seem appropriate.
Move LocalKeyStore to com.fsck.k9.security
Move TrustManagerFactory and TrustedSocketFactory to com.fsck.k9.net.ssl
Also, implement the ability to configure an alternate key store
file location. This permits the running of unit tests without
clobbering the live key store file.
Also, add a test to confirm that the key store file is being written
out and reread correctly.
Proper host name validation was not being performed for certificates
kept in the local keystore. If an attacker could convince a user to
accept and store an attacker's certificate, then that certificate
could be used for MITM attacks, giving the attacker access to all
connections to all servers in all accounts in K-9.
This commit changes how the certificates are stored. Previously, an
entire certificate chain was stored for a server (and any of those
certificates in the chain were available for validating signatures on
certificates received when connecting). Now just the single
certificate for the server is stored.
This commit changes how locally stored certificates are retrieved.
They can only be retrieved using the host:port that the user
configured for the server.
This also fixes issue 1326. Users can now use different certificates
for different servers on the same host (listening to different ports).
The above changes mean that users might have to re-accept certificates
that they had previously accepted and are still using (but only if the
certificate's Subject doesn't match the host that they are connecting
to).
This commit modifies AccountSetupBasics so that it now calls
AccountSetupCheckSettings twice -- once for checking the incoming
settings and once for the outgoing settings. Otherwise, an exception
could occur while checking incoming settings, the user could say
continue (or the user could accept a certificate key), and the
outgoing settings would not be checked. This also helps with
determining if a certificate exception was for the incoming or
outgoing server, which is needed if the user decides to add the
certificate to the keystore.
This string resource is used in two places -- both with and without the
linefeed at the end. Instead of having a linefeed in the string and
having the code remove it if not needed, the linefeed is now omitted from
the string and the code adds it if needed.
Also, the line ending is changed from \n to \r\n.
Also, the string in the DE and FR locales had linefeeds at the start that
were removed so they match all the other locales.
(The string in the zh-rTW locale was left alone, since it had no
linefeeds. It looks like that file has numerous instances where \n was
replaced with actual newlines, which is probably not correct.)
This builds upon the efforts started 2 commits back where \r\n is used for
all message text and \n is only used when the text is inside an
EolConvertingEditText widget.
Even with the fix in the parent commit, the X-K9mail-Identity header can
become invalid if, for example, a user creates a draft in K-9 Mail, then
edits the draft outside of K-9 Mail, then opens the draft again in K-9
Mail.
This commit assures that an invalid X-K9mail-Identity header will not
result in an IndexOutOfBoundsException.
The problem:
Configure the account (just an example -- problems can occur in other
configurations as well):
Message Format: HTML
Reply quoting style: Prefix
Quote message when replying: yes
Reply after quoted text: yes
Reply to a message that has a large quantity (20+) of \r\n scattered in
the body of its HTML version (not an unusual scenario).
Add a reply. Save the message as a draft. Go back & open the draft
again. A fatal IndexOutOfBoundsException occurs.
The cause:
When the draft was saved, the X-K9mail-Identity header was computed and
added to the message, then the text of the message was processed with
MimeUtility.fixDraftTextBody, replacing all occurrences of \r\n with \n in
the quoted message before being saved in LocalStore, thus invalidating the
X-K9mail-Identity header.
The fix:
Remove MimeUtility.fixDraftTextBody and implement
MessageCompose$EolConvertingEditText instead. Any message text placed in
an EolConvertingEditText widget is assured to have \n line endings. Any
message text extracted from an EolConvertingEditText widget is assured to
have \r\n line endings. The X-K9mail-Identity header will always be
computed correctly.

As noted in some of the referenced issues, errors didn't always result in
a fatal exception, but instead with mixed up text.

Update LocalStore code to handle the newly introduced temporary files
for attachments
Conflicts:
res/values/strings.xml

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
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.
