If a leaf part's body content is omitted, return the encoded length and
transfer encoding in --format=json output. This information may be used
by the consumer, e.g. to decide whether to download a large attachment
over a slow link.
Returning the _encoded_ content length is more efficient than returning
the _decoded_ content length. Returning the transfer encoding allows
the consumer to estimate the decoded content length.
Write a "charset" field for all omitted parts for which it is applicable,
not only text/html parts. Factor out the code to a separate function.
It will be extended with more fields next.
All the structured output functions in notmuch-reply and notmuch-show
are renamed to a generic name (as they do not contain any json-specific
code anyway). This patch is a preparation to actually using the new
S-Expression sprinter in notmuch-reply and notmuch-show.
Previously, the only mention of devel/schemata was a comment at the
top of format_part_json, but the JSON output code is spread across
several functions that are distributed across notmuch-show.c. Add
references from the other three key JSON output functions.
Output the Reply-To header field if present in a message.
I want to be able to see what the sender intended in my mail client,
before hitting the reply key. Only json output is changed,
like the recently added Bcc field.
Unlike the previous patches, this function is used for all formats.
However, for formats other than the JSON format, the sprinter methods
used by show_message are all no-ops, so this code continues to
function correctly for all of the formats.
Converting show_message eliminates show_null_message in the process,
since this maps directly to an sprinter method.
There are several levels of function calls between where we create the
sprinter and the call to the part formatter in show_message. This
feeds the sprinter through all of them and into the part formatters.
This associates an sprinter constructor with each show format and uses
this to construct the appropriate sprinter. Currently nothing is done
with this sprinter, but the following patches will weave it through
the layers of notmuch show.
This option allows the caller to suppress the output of the bodies of
the messages. Currently this is only implemented for format=json.
This is used by notmuch-pick.el (although not needed) because it gives
a speed-up of at least a factor of a two (and in some cases a speed up
of more than a factor of 8); moreover it reduces the memory usage in
emacs hugely.
The --entire-thread option in notmuch-show.c defaults to true when
format=json. Previously there was no way to turn this off. This patch
makes it respect --entire-thread=false.
To do this the patch moves the --entire-thread option to be a keyword
option using the new command line parsing to allow the existing
--entire-thread to keep working.
All formats except Json can output empty messages for non
entire-thread, but in Json format we output "null" to keep the other
elements (e.g. the replies to the omitted message) in the correct
place.
This has the affect of lazily creating the crypto contexts only when
needed. This removes code duplication from notmuch-show and
notmuch-reply, and should speed up these functions considerably if the
crypto flags are provided but the messages don't have any
cryptographic parts.
Use this flag rather than depend on the existence of an initialized
gpgctx, to determine whether we should verify a multipart/signed. We
will be moving to create the ctx lazily, so we don't want to depend on
it being previously initialized if it's not needed.
It has been a long-standing issue that notmuch_database_open doesn't
return any indication of why it failed. This patch changes its
prototype to return a notmuch_status_t and set an out-argument to the
database itself, like other functions that return both a status and an
object.
In the interest of atomicity, this also updates every use in the CLI
so that notmuch still compiles. Since this patch does not update the
bindings, the Python bindings test fails.
This moves notmuch show to the --exclude=(true|false) naming
scheme. When exclude=false show returns all threads that match
including those that only match in an excluded message. The excluded
messages are flagged.
When exclude=true the behaviour depends on whether --entire-thread is
set. If it is not set then show only returns the messages which match
and are not excluded. If it is set then show returns all messages in
the threads that match in a non-excluded message, flagging the excluded
messages in these threads. The rationale is that it is awkward to use
a thread with some missing messages.
Previously, show and reply had separate implementations of decoding
and printing text parts. Now both use show's implementation, which
was more complete. Show's implementation has been extended with an
option to add reply quoting to the extracted part (this is implemented
as a named flag to avoid naked booleans, even though it's the only
flag it can take).
This new JSON format for replies includes headers generated for a
reply message as well as the headers of the original message. Using
this data, a client can intelligently create a reply. For example, the
emacs client will be able to create replies with quoted HTML parts by
parsing the HTML parts.
This is fully compatible for root and leaf parts, but now has proper
support for interior parts. This requires some design decisions that
were guided by what I would want if I were to save a part.
Specifically:
- Leaf parts are printed without headers and with transfer decoding.
This is what makes sense for saving attachments. (Furthermore, the
transfer decoding is necessary since, without the headers, the
caller would not be able to interpret non-transfer-decoded output.)
- Message parts are printed with their message headers, but without
enclosing part headers. This is what makes sense for saving a
message as a whole (which is a message part) and for saving attached
messages. This is symmetric for whole messages and for attached
messages, though we special-case the whole message for performance
reasons (and corner-case correctness reasons: given malformed input,
GMime may not be able to reproduce it from the parsed
representation).
- Multipart parts are printed with their headers and all child parts.
It's not clear what the best thing to do for multipart is, but this
was the most natural to implement and can be justified because such
parts can't be interpreted without their headers.
As an added benefit, we can move the special-case code for part 0 into
the raw formatter.
Formatter errors are propagated to the exit status of notmuch show.
This isn't used by the JSON or text formatters, but it will be useful
for the raw format, which is pickier.
In all cases of notmuch count/search/show where the results returned
cannot reflect the exclude flag return just the matched not-excluded
results. If the caller wishes to have all the matched results (i.e.,
including the excluded ones) they should call with the
--no-exclude option.
The relevant cases are
count: both threads and messages
search: all cases except the summary view
show: mbox format
This adds the excludes to notmuch-show.c. We do not exclude when only
a single message (or part) is requested. notmuch-show will output the
exclude information when either text or json format is requested. As
this changes the output from notmuch-show it breaks many tests (in a
trivial and expected fashion).
This has three ramifications:
- Blank To and Cc headers are no longer output for messages.
- Dates are now canonicalized for messages, which means they always
have a day of the week and GMT is printed +0000 (never -0000)
- Invalid From message headers are handled slightly differently, since
they get parsed by GMime now instead of notmuch.
Previously, top-level message headers were printed as Subject, From,
To, Date, while embedded message headers were printed From, To,
Subject, Date. This makes both cases use the former order and updates
the tests accordingly.
As before, this is all code movement and a smidgen of glue. This
moves the existing JSON formatter code into one self-recursive
function, but doesn't change any of the logic to take advantage of the
new structure.
In general, "leafs" of the JSON structure are left in helper functions
(most of them untouched), so that it's easy to see the overall
structure of the format from the main recursive function.
The last lines of notmuch_show_command() function were
unreachable. Fix it by using a variable for return value.

Use the new notmuch argument parser to handle arguments in "notmuch
show". There are three minor functional changes:
1) Also set params.raw = TRUE when defaulting to raw format when part
is requested but format is not specified. This was a bug, and
--part=0 without --format=raw did not work previously.
2) Set params.decrypt = FALSE if crypto context creation fails.
3) Only use the parameters for the last --format if specified multiple
times. Previously this could have resulted in a non-working mixture
of parameters.
