Commit 0f314c0c99 ("cli: convert notmuch_bool_t to stdbool")
over-eagerly converted EXCLUDE_TRUE and EXCLUDE_FALSE to EXCLUDE_true
and EXCLUDE_false in notmuch-count.c. We could just fix the case back,
but convert the option to an actual boolean argument instead.
We've used a keyword argument rather than a boolean argument for
notmuch count --exclude for five years, since commit 785c1e497f
("cli: move count to the new --exclude=(true|false|flag) naming
scheme."), "to allow future options to be added more easily". I think
we can conclude future options aren't coming any time soon.
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.
Fix the following cppcheck errors:
notmuch-count.c:207: error: Resource leak: input
notmuch-tag.c:238: error: Resource leak: input
We know that the program is shutting down here, but it does no harm to
clean up a bit.
This function was deprecated in notmuch 0.21. We re-use the name for
a status returning version, and deprecate the _st name. One or two
remaining uses of the (removed) non-status returning version fixed at
the same time
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.
This brings back status information that may have been hidden by the
great library logging conversion.
Note the change of the internal API / return-value for count_files. The
other count calls to the lib will also get error handling when that API
is updated in the lib.
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 the short term we need a way to get lastmod information e.g. for
the test suite. In the long term we probably want to add lastmod
information to at least the structured output for several other
clients (e.g. show, search).
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.
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.
Add support for querying the total number of files associated with the
messages matching the search. This is mostly useful with an
id:<message-id> query for a single message.
Add support for reading queries from stdin, one per line, and writing
results to stdout, one per line.
This will bring considerable performance improvements when utilized in
Emacs notmuch-hello, especially so when running remote notmuch.
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.
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.
Move the option --no-exclude to the --exclude= scheme. Since there is
no way to flag messages only true and false are implemented. Note
that, for consistency with other commands, this is implemented as a
keyword option rather than a boolean option.
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
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.
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.
previously we deleted the subcommand name from argv before passing to
the subcommand. In this version, the deletion is done in the actual
subcommands. Although this causes some duplication of code, it allows
us to be more flexible about how we parse command line arguments in
the subcommand, including possibly using off-the-shelf routines like
getopt_long that expect the name of the command in argv[0].
From both the implementation and from the documentation. This is
handled generically in the library for all search-based commands,
so count doesn't need special treatment.
If no parameters are given to notmuch-count, or just '' or '*' are
given, return the total number of messages in the database.
update notmuch count help
Getting the count of matching threads or messages is a fairly
expensive operation. Xapian provides a very efficient mechanism that
returns an approximate value, so use that for this new command.
This returns the number of matching messages, not threads, as that is
cheap to compute.
