I was having trouble understanding the logic of the longish print_view
function, so I refactored the output generation into modular bits.
The basic text rendering is handled by Page, which has enough hooks
that HtmlPage can borrow the logic and slot-in HTML generators.
By modularizing the logic it should also be easier to build other
renderers if folks want to customize the layout for other projects.
Timezones
=========
This commit has not effect on the output, except that some dates have
been converted from the sender's timezone to UTC due to:
- val = m.get_header(header)
- ...
- if header == 'date':
- val = str.join(' ', val.split(None)[1:4])
- val = str(datetime.datetime.strptime(val, '%d %b %Y').date())
...
+ value = str(datetime.datetime.utcfromtimestamp(
+ message.get_date()).date())
I also tweaked the HTML header date to be utcnow instead of the local
now() to make all times independent of the generator's local time.
This matches Gmane, which converts all Date headers to UTC (although
they use a 'GMT' suffix). Notmuch uses
g_mime_utils_header_decode_date to calculate the UTC timestamps, but
uses a NULL tz_offset which drops the information we'd need to get
back to the sender's local time [1]. With the generator's local time
arbitrarily different from the sender's and viewer's local time,
sticking with UTC seems the best bet.

Make this all one big string, using '...{date}...'.format(date=...) to
inject the date [1]. This syntax was added in Python 2.6, and is
preferred to %-formatting in Python 3 [1].

The database in only used for notmuch.Query, so there's no need for
write access. This allows nmbug-status to run while the database is
being updated, without raising:
A Xapian exception occurred opening database: Unable to get write lock on …: already locked
Traceback (most recent call last):
File "./nmbug-status", line 182, in <module>
db = notmuch.Database(mode=notmuch.Database.MODE.READ_WRITE)
File "/…/notmuch/database.py", line 154, in __init__
self.open(path, mode)
File "/…/notmuch/database.py", line 214, in open
raise NotmuchError(status)
notmuch.errors.XapianError
The definitions of Thread, output_with_separator, and print_view were
between the main argparse and view-printing code. Group them together
with our existing read_config at the top of the module, which makes
for easier reading in the main section.
I also:
* Made 'headers' a print_view argument instead of a module-level
global. The list -> tuple conversion avoids having a mutable
default argument, which makes some people jumpy ;).
* Made 'db' a print_view argument instead of relying on the global
namespace to access it from print_view.
Now the suggested usage (listed by 'nmbug-status --help') is:
usage: nmbug-status [-h] [--text] [--config PATH] [--list-views]
[--get-query VIEW]
instead of the less obvious:
usage: nmbug-status [-h] [--text] [--config CONFIG] [--list-views]
[--get-query GET_QUERY]
Avoid:
$ ./nmbug-status --list-views
Traceback (most recent call last):
File "./nmbug-status", line 47, in <module>
'cat-file', 'blob', sha1+':status-config.json'],
TypeError: can't concat bytes to str
by explicitly converting the byte-stream read from Popen into a
Unicode string. On Python 2, this conversion is str -> unicode; on
Python 3 it is bytes -> str.
_ENCODING is derived from the user's locale (or system default) in an
attempt to match Git's output encoding. It may be more robust to skip
the encoding/decoding by using a Python wrapper like pygit2 [1] for
Git access. That's a fairly heavy dependency though, and using the
locale will probably work.

This is a pretty basic config to get started, generated using 'doxygen
-s -g' and mildly tweaked.
To generate the library man page man/man3/notmuch.3 from lib/notmuch.h
use:
$ doxygen devel/doxygen.cfg
NOTMUCH_VERSION_* macros in lib/notmuch.h are replaced with
LIBNOTMUCH_VERSION_* macros. Check that the values of those
match the LIBNOTMUCH_*_VERSION values in lib/Makefile.local.
New defines NOTMUCH_MAJOR_VERSION, NOTMUCH_MINOR_VERSION and
NOTMUCH_MICRO_VERSION were added to lib/notmuch.h.
Check that these match the current value defined in ./version.
This fixes races in thread-local and global tagging in notmuch-search
(e.g., "+", "-", "a", "*", etc.). Previously, these would modify tags
of new messages that arrived after the search. Now they only operate
on the messages that were in the threads when the search was
performed. This prevents surprises like archiving messages that
arrived in a thread after the search results were shown.
This eliminates `notmuch-search-find-thread-id-region(-search)'
because these functions strongly encouraged racy usage.
This fixes the two broken tests added by the previous patch.
These queries will match exactly the set of messages currently in the
thread, even if more messages later arrive. Two queries are provided:
one for matched messages and one for unmatched messages.
This can be used to fix race conditions with tagging threads from
search results. While tagging based on a thread: query can affect
messages that arrived after the search, tagging based on stable
queries affects only the messages the user was shown in the search UI.
Since we want clients to be able to depend on the presence of these
queries, this ushers in schema version 2.
Previously, the show schema and the search schema used different
"thread" non-terminals. While these schemata don't interact, this is
still confusing, so rename search's "thread" to "thread_summary". To
further limit confusion, prefix all top-level search non-terminals now
begin with "search_".
I find this script pretty useful when figuring out who to blame for
MIME rendering problems.
The notmuch repo will be the new primary home for this script, unless
and until a better home turns up.
After new notmuch release has been published the NEWS and manual
pages have been updated using these 2 programs.
Adding the tools to notmuch repository eases their use, adds more
transparency to the "process" and gives more people chance to
do the updates is one is unavailable to do it at the time being.
Current code does not distinguish between an empty string in the
NMBPREFIX environment variable and the variable being undefined. This
makes it impossible to define an empty prefix, if, e.g. somebody wants
to dump all of their tags with nmbug.
This is at least easier to understand than the magic hash. It may also
be a bit more robust, although it is hard to imagine these numbers
changing without many other changes in git.
This should be more robust with respect to tags with whitespace and
and other special characters. It also (hopefully) fixes a remaining
bug handling message-ids with whitespace. It should also be
noticeably faster for large sets of changes since it does one exec per
change set as opposed to one exec per tag changed.
This should make nmbug tolerate tags with whitespace and other special
characters it. At the moment this relies on _not_ passing calls to
notmuch tag through the shell, which is a documented feature of perl's
system function.
Check that the underlining '===...' for first (header) line in NEWS
file is of the same length as the header text and it is all '=':s.
-- extra execs removed by db.
There seems to be consensus to use presence in contrib as
documentation of limited support by the notmuch developers; in fact
nmbug is pretty integrated into our current development process, so
devel seems more appropriate.
M-RET notmuch-show-open-or-close-all opens all closed messages.
The archiving change is mentioned twice, remove dupe.
"notmuch search" supports --format=text0 to work with xargs -0
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.
Version string has strict format requirements in release-check.sh:
only numbers and periods (in sane order) are accepted.
Mismatch there used to halt further execution.
In this case, checking versions like '*~rc1' for (more) problems
was not possible.
This 'fatal error' is now changed buffered error message like in
following tests, and is displayed at the end of execution.
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.
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.
Added FILE, notmuch_show_params_t and sprinter_t to be
types when uncrustifying sources. This affect spacing
when uncrustify is deciding for type declaration instead
of binary multiplication operation.
Currently Makefile.local contains some machine executable release
checking functionality. This is unnecessarily complex way to do it:
Multiline script functionality is hard to embed -- from Makefile point
of view there is just one line split using backslashes and every line
ends with ';'. It is hard to maintain such "script" when it gets longer.
The embedded script does not fail as robust as separate script; set -eu
could be added to get same level of robustness -- but the provided
Bourne Again Shell (bash) script exceeds this with 'set -o pipefail',
making the script to fail when any of the commands in pipeline fails
(and not just the last one).
Checking for release is done very seldom compared to all other use;
The whole Makefile.local gets simpler and easier to grasp when most
release checking targets are removed.
When release checking is done, the steps are executed sequentially;
nothing is allowed to be skipped due to some satisfied dependency.
Previously body: was a compulsory field in a message. The new
--body=false option causes notmuch show to omit this field so update
schemata to reflect this.
In id:"87sjdm12d1.fsf@awakening.csail.mit.edu" Austin pointed out that
devel/schemata needs a slight correction with the new
--entire-thread=false option. This is that correction.
Changes to devel/uncrustify.cfg:
* Updated header comment to state this is config file for *notmuch*.
* Added comment about the reason of 'type' keyword used.
* Added some more custom types woth 'type' keyword.
* Have (every) multiline comment lines start with '*'.
Adjusted some uncrustify variables to get closer to prevailing style:
* Label indent (for goto) relative to current indentation.
* Registered GMimeObject and mime_node_t being as types.
* Space after ! (not) operator.
* No space after 'stringify' (#) preprosessor token.
* No spacing change around ## (option not versatile enough).
There are at least 3 cases where attention needs to be paid:
* If there is newline between function name and open paren in function
call, the paren (and args) are indented too far right.
* #define HOUR (60 *MINUTE) -- i.e. no space after star (*).
* void (*foo)(args) -- i.e no space between (name) and (args).
Uncrustify is a free (as in GPL2+) tool that indents and beautifies
C/C++ code. It is similar to GNU indent in functionality although
probably more configurable (in fairness, indent has better
documentation). Uncrustify does not have the indent mis-feature of
needing to have every typedef'ed type defined in the
configuration (even standard types like size_t).
This configuration starts with the linux-kernel style from the
uncrustify config, disables aggressive re-indenting of structs,
and fine tunes the handling 'else' and braces.
In an ideal situation, running uncrustify on notmuch code would be
NOP; currently this is not true for all files because 1) the
configuration is not perfect 2) the coding style of notmuch is not
completely consistent; in particular the treatment of braces after
e.g. for (_) is not consistent.
Some fine tuning by Tomi Olilla.
