While looked good on paper, its attempted use caused confusion, complexity,
and potential for information leak when passed through wrapper scripts.
For slimmer code and to lessen demand for maintenance/support the set of
commits which added top level --stderr= option is now reverted.
With this option all writes to stderr are redirected to the specified
FILE (or to stdout on case FILE is '-'). This is immediately useful
in emacs interface as some of its exec intefaces do not provide
separation of stdout and stderr.
This allows specifying config file as a top level argument to notmuch,
and generally makes it possible to override config file options in
main(), without having to touch the subcommands.
If the config file does not exist, one will be created for the notmuch
main command and setup and help subcommands. Help is special in this
regard; the config is created just to avoid errors about missing
config, but it will not be saved.
This also makes notmuch config the talloc context for subcommands.
We now have a notmuch_config_is_new() function to query whether a
config was created or not. Change the notmuch_config_open() is_new
parameter into boolean create_new to determine whether the function
should create a new config if one doesn't exist. This reduces the
complexity of the API.
Keep track of whether the config is newly created, and add
notmuch_config_is_new() accessor function to query this.
This is to support anyone with a config handle to check this, instead
of just whoever called notmuch_config_open().
Currently there is a period of pain whenever we make
backward-incompatible changes to the structured output format, which
discourages not only backward-incompatible improvements to the format,
but also backwards-compatible additions that may not be "perfect". In
the end, these problems limit experimentation and innovation.
This series of patches introduces a way for CLI callers to request a
specific format version on the command line and to determine if the
CLI does not supported the requested version (and perhaps present a
useful diagnostic to the user). Since the caller requests a format
version, it's also possible for the CLI to support multiple
incompatible versions simultaneously, unlike the alternate approach of
including version information in the output.
This patch lays the groundwork by introducing a versioning convention,
standard exit codes, and a utility function to check the requested
version and produce standardized diagnostic messages and exit
statuses.
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.
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.
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.
This new structure, notmuch_crypto_t, keeps all relevant crypto
contexts and parameters together, and will make it easier to pass the
stuff around and clean it up. The name of the crypto context inside
this new struct will change, to reflect that it is actually a GPG
context, which is a sub type of Crypto context. There are other types
of Crypto contexts (Pkcs7 in particular, which we hope to support) so
we want to be clear.
The new crypto.c contains functions to return the proper context from
the struct for a given protocol (and initialize it if needed), and to
cleanup a struct by releasing the crypto contexts.
gmime 2.4 defines GMimeCipherContext, while 2.6 defines
GMimeCryptoContext. typedef them both to notmuch_crypto_context_t to
cover this discrepancy and remove a bunch of #ifdefs.
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.
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.
A new configuration key 'new.ignore' is used to determine which
files and directories user wants not to be scanned as new mails.
Mark the corresponding test as no longer broken.

This callback is the gateway to the new mime_node_t-based formatters.
This maintains backwards compatibility so the formatters can be
transitioned one at a time. Once all formatters are converted, the
formatter structure can be reduced to only message_set_{start,sep,end}
and part, most of show_message can be deleted, and all of
show-message.c can be deleted.
This makes the part numbers readily accessible to formatters.
Hierarchical part numbering would be a more natural and efficient fit
for MIME and may be the way to go in the future, but depth-first
numbering maintains compatibility with what we currently do.
All other config-related functions and args include the section
title in their name, so for the sake of consistency, mirror that.
Also, the "auto"matic part is a given, so that was dropped.
There are lots of API changes in gmime 2.6 crypto handling. By adding
preprocessor directives, it is however possible to add gmime 2.6 compatibility
while preserving compatibility with gmime 2.4 too.
This is mostly based on id:"8762i8hrb9.fsf@bookbinder.fernseed.info".
This was tested against both gmime 2.6.4 and 2.4.31. With gmime 2.4.31, the
crypto tests all work fine (as expected). With gmime 2.6.4, one crypto test is
currently broken (signature verification with signer key unavailable), most
likely because of a bug in gmime which will hopefully be fixed in a future
version.
This adds a "search" section to the config file and an
"auto_tag_exclusions" setting in that section. The search and count
commands pass tag tags from the configuration to the library.
This function matches how we number parts for the --part argument to
show. It will allow us to jump directly to the desired part, rather
than traversing the entire tree and carefully tracking whether or not
we're "in the zone".
This wraps all of the complex MIME part handling in a single, simple
function that gets part N from *any* MIME object, so traversing a MIME
part tree becomes a two-line for loop. Furthermore, the MIME node
structure provides easy access to envelopes for message parts as well
as cryptographic information.
This code is directly derived from the current show_message_body code
(much of it is identical), but the control relation is inverted:
instead of show_message_body controlling the traversal of the MIME
structure and invoking callbacks, the caller controls the traversal of
the MIME structure.
Add mechanism for running user defined hooks. Hooks are executables or
symlinks to executables stored under the new notmuch hooks directory,
<database-path>/.notmuch/hooks.
No hooks are introduced here, but adding support for a hook is now a simple
matter of calling the new notmuch_run_hook() function at an appropriate
location with the hook name.

As we noticed when Jani kindly converted things to getopt_long, much
of the work in argument parsing in notmuch is due to the the key-value
style arguments like --format=(raw|json|text).
The framework here provides positional arguments, simple switches,
and --key=value style arguments that can take a value being an integer,
a string, or one of a set of keywords.
This new function takes a GMimeMessage as input, and outputs the
formatted headers. This allows for message/rfc822 parts to be
formatted on output in a similar way to full messages (see previous
patch that overhauls the multipart test for more info).
Our use of GMimeSession was unneeded boilerplate, and we weren't doing
anything with it. This simplifies and clarifies that assumption.
If we want to do anything fancier later, the examples in the gmime
source are a reasonable source to work from in defining a new
GMimeSession derivative.
Since GMimeSession is going away in GMime 2.6, though, i don't
recommend using it.
This adds support for decrypting PGP/MIME-encrypted parts to
notmuch-show and notmuch-reply. The --decrypt option implies
--verify. Once decryption (and possibly signature verification) is
done, a new part_encstatus formatter is emitted, the part_sigstatus
formatter is emitted, and the entire multipart/encrypted part is
replaced by the contents of the encrypted part.
At the moment only a json part_encstatus formatting function is
available, even though decryption is done for all formats. Emacs
support to follow.
This is primarily for notmuch-show, although the functionality is
added to show-message. Once signatures are processed a new
part_sigstatus formatter is emitted, and the entire multipart/signed
part is replaced with the contents of the signed part.
At the moment only a json part_sigstatus formatting function is
available. Emacs support to follow.
The original work for this patch was done by
Daniel Kahn Gillmor <dkg@fifthhorseman.net>
whose help with this functionality I greatly appreciate.
Future improvements (eg. crypto support) will require adding new part
header. By breaking up the output of part headers from the output of
part content, we can easily out new part headers with new formatting
functions.
Outputting of single MIME parts is moved to an option of notmuch show,
instead of being handled in it's own sub-command. The recent rework
of multipart mime allowed for this change but consolidating part
handling into a single recursive function (show_message_part) that
includes formatting. This allows for far simpler handling single
output of a single part, including formatting.
We rename here in order to make do_show_single into a generic function
for handling output of just a single message, or which format=raw is a
special case. The raw case is handled by setting a new parameter,
params.raw, which is used to tell do_show_single to output a single
message as a raw file.
This is mostly in preparation for much improved part handling to
follow imminently.
A new field "part_sep" is added to the notmuch_show_format structure,
to be used for part separation. This is cleaner than the "first"
argument that was being passed around to the part arguments, and
allows the function that handles overall part output formatting
(show_message_part) to directly handle when outputting the separator.
This simplifies the passing of arguments to the show functions. This
will be very useful as we accumulate more parameters that will need to
be passed. Currently only the entire_thread parameter is passed this
way.
Various show_message* functions require formatting functions, which
were previously being passed individually as arguments. Since we will
need to be needing to passing in more formatting function in the
future (ie. for crypto support), we here modify things so that we just
pass in the entire format structure. This will make things much
simpler down the line as we need to pass in new format functions.
We move the show_format structure into notmuch-client.c as
notmuch_show_format. This also affects notmuch-reply.c, so we create
a mostly-empty format_reply to pass the reply_part function to
show_message_body.
Previously, notmuch show flattened all output, losing information
about the nesting of the MIME hierarchy. Now, the output is properly
nested, (both in the --format=text and --format=json output), so that
clients can analyze the original MIME structure.
Internally, this required splitting the final closing delimiter out of
the various show_part functions and putting it into a new
show_part_end function instead. Also, the show_part function now
accepts a new "first" argument that is set not only for the first MIME
part of a message, but also for each first MIME part within a series
of multipart parts. This "first" argument controls the omission of a
preceding comma when printing a part (for json).
Many thanks to David Edmondson <dme@dme.org> for originally
identifying the lack of nesting in the json output and submitting an
early implementation of this feature. Thanks as well to Jameson Graef
Rollins <jrollins@finestructure.net> for carefully shepherding David's
patches through a remarkably long review process, patiently explaining
them, and providing a cleaned up series that led to this final
implementation. Jameson also provided the new emacs code here.
Since the name of the configuration parameter here is:
maildir.synchronize_flags
the convention is that the functions to get and set this parameter
should match it in name. Hence:
notmuch_config_get_maildir_synchronize_flags
etc. (as opposed to notmuch_config_get_maildir_sync).
