This new automatic decryption policy should make it possible to
decrypt messages that we have stashed session keys for, without
incurring a call to the user's asymmetric keys.
Future patches in this series will introduce new policies; this merely
readies the way for them.
We also convert --try-decrypt to a keyword argument instead of a boolean.
the command-line interface for indexing (reindex, new, insert) used
--try-decrypt; and the configuration records used index.try_decrypt.
But by comparison with "show" and "reply", there doesn't seem to be
any reason for the "try" prefix.
This changeset adjusts the command-line interface and the
configuration interface.
For the moment, i've left indexopts_{set,get}_try_decrypt alone. The
subsequent changeset will address those.
"notmuch help" doesn't mention "notmuch-emacs-mua" even though we
support it through the try_external_command() mechanism.
In addition, "notmuch help emacs-mua" doesn't work, even though we
ship the appropriate manpage.
This changeset fixes both of these problems.
We have an indexopts structure for manipulating indexing in different
ways, but we also have three command-line invocations that can trigger
indexing: new, insert, and reindex.
This changeset prepares a common parser that these subcommands can
share.
Note: if the deprecated crypto.gpg_path configuration option is set to
anything other than "gpg", we ignore it (and print a warning on
stderr, if built against gmime < 3.0).
At the moment, it's just --try-decrypt, but others will likely follow.
C99 stdbool turned 18 this year. There really is no reason to use our
own, except in the library interface for backward
compatibility. Convert the cli and test binaries to stdbool.
Several changes at once, just to not have to change the same lines
several times over:
- Use designated initializers to initialize opt desc arrays.
- Only initialize the needed fields.
- Remove arg_id (short options) as unused.
- Replace opt_type and output_var with several type safe output
variables, where the output variable being non-NULL determines the
type. Introduce checks to ensure only one is set. The downside is
some waste of const space per argument; this could be saved by
retaining opt_type and using a union, but that's still pretty
verbose.
- Fix some variables due to the type safety. Mostly a good thing, but
leads to some enums being changed to ints. This is pedantically
correct, but somewhat annoying. We could also cast, but that defeats
the purpose a bit.
- Terminate the opt desc arrays using {}.
The output variable type safety and the ability to add new fields for
just some output types or arguments are the big wins. For example, if
we wanted to add a variable to set when the argument is present, we
could do so for just the arguments that need it.
Beauty is in the eye of the beholder, but I think this looks nice when
defining the arguments, and reduces some of the verbosity we have
there.
If the given subcommand is not known to notmuch, try to execute
external notmuch-<subcommand> instead. This allows users to have their
own notmuch related tools be run via the notmuch command, not unlike
git does. Also notmuch-emacs-mua will be executable via 'notmuch
emacs-mua'.
By design, this does not allow notmuch's own subcommands to be
overriden using external commands.
Many of the external links found in the notmuch source can be resolved
using https instead of http. This changeset addresses as many as i
could find, without touching the e-mail corpus or expected outputs
found in tests.
The function notmuch_exit_if_unmatched_db_uuid is split from
notmuch_process_shared_options because it needs an open notmuch
database.
There are two exceptional cases in uuid handling.
1) notmuch config and notmuch setup don't currently open the database,
so it doesn't make sense to check the UUID.
2) notmuch compact opens the database inside the library, so we either
need to open the database just to check uuid, or change the API.
In particular this fixes a recently encountered bug where the
"--config" argument to "notmuch setup" is silently ignored, which the
unpleasant consequence of overwriting the users config file.
Unfortunately it seems trickier to support --config globally
The non-trivial changes are in notmuch.c; most of the other changes
consists of blindly inserting two lines into every subcommand.
We call it with NULL at one point anyway, so it needs to work with
NULL. Since the only place we use talloc is right before exec, there
is no harm in always using NULL.
Recognize 'notmuch command --help' at the top level as a special case,
and show help for the command. Note that for simplicity, --help is
only recognized as the first option for the subcommand.
If the top level --help is combined with other options, help
fails. For example:
$ notmuch --version --help
Sorry, --help is not a known command. There's not much I can do to help.
Fix this by adjusting argc and argv appropriately. The help command
ignores argv[0] anyway, so we don't have to set it to "help".
This moves address-related functionality from search command to the
new address command. The implementation shares almost all code and
some command line options.
Options --offset and --limit were intentionally not included in the
address command, because they refer to messages numbers, which users
do not see in the output. This could confuse users because, for
example, they could see more addresses in the output that what was
specified with --limit. This functionality can be correctly
reimplemented for address subcommand later.
Also useless values of --exclude flag were not included in the address
command.
This was inspired by a patch from Jani Nikula.
Apart from the status codes for format mismatches, the non-zero exit
status codes have been arbitrary. Make the cli consistently return
either EXIT_SUCCESS or EXIT_FAILURE.
Previously, the CLI would print a deprecation warning if a client
requested any format version other than the current one. However, if
we add fields that are backwards-compatible, but want clients to be
able to depend on, we need to bump the version, but that doesn't make
the older version deprecated.
Hence, separate out the "minimum active" version and only print a
warning for requests below this version number.

The notmuch insert command reads a message from standard input,
writes it to a Maildir folder, and then incorporates the message into
the notmuch database. Essentially it moves the functionality of
notmuch-deliver into notmuch.
Though it could be used as an alternative to notmuch new, the reason
I want this is to allow my notmuch frontend to add postponed or sent
messages to the mail store and notmuch database, without resorting to
another tool (e.g. notmuch-deliver) nor directly modifying the maildir.
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.
This allows top level arguments to be added to notmuch in a way that
doesn't require special handling for the plain notmuch command without
a subcommand.
This really should have been there before. I think it's better to do
the actual operation and then possibly fail writing the memory log,
but it would not be too hard to change it to abort earlier.
The commands are long deprecated, so removal is probably overdue. The
real motivation is to simplify argument handling for notmuch so that
we can migrate to the common argument parsing framework.
The argument handling in notmuch.c seems due for an overhaul, but
until then use an environment variable to specify a location to write
the talloc leak report to. This is only enabled for the (interesting)
case where some notmuch subcommand is invoked.
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.
"notmuch help" now relies on a working man installation, and a correct
setting of MANPATH, for users that install in "unusual" places. This
should probably noted in NEWS before shipping.
There is still some small duplication of docs as the one line
summaries are hard coded in the binary. This seems preferable to
complicated script games, at least as long was we are using a
presentation level markup like nroff.
Run notmuch new pre and post hooks, named "pre-new" and "post-new", if
present in the notmuch hooks directory. The hooks will be run before and
after incorporating new messages to the database.
Typical use cases for pre-new and post-new hooks are fetching or delivering
new mail to the maildir, and custom tagging of the mail incorporated to the
database.
Also add command line option --no-hooks to notmuch new to bypass the hooks.

When I changed the calling convention to pass in all but the zero-th
argument to subcommands, I missed this one call, resulting in a
segmentation fault.
As a bonus, the syntax "notmuch --help foo" is now equivalent to
"notmuch help foo".
Add options --offset=[-]N and --limit=M to notmuch search to determine the
first result and maximum number of results to display.
Option --limit=M limits the maximum number of results to display to M.
Option --offset=[-]N skips the first N results; with the leading '-' skip
until the Nth result from the end.
Note that --offset with a negative N for thread or summary output requires
counting the number of matching threads in advance.
