d9d3d3e6f0 Make maildir synchronization configurable
This adds group [maildir] and key 'synchronize_flags' to the
configuration file. Its value enables (true) or diables (false) the
synchronization between notmuch tags and maildir flags. By default,
the synchronization is disabled.

088801a14a Maildir synchronization
This patch allows bi-directional synchronization between maildir
flags and certain tags. The flag-to-tag mapping is defined by flag2tag
array.

The synchronization works this way:

1) Whenever notmuch new is executed, the following happens:
   o New messages are tagged with configured new_tags.
   o For new or renamed messages with maildir info present in the file
     name, the tags defined in flag2tag are either added or removed
     depending on the flags from the file name.

2) Whenever notmuch tag (or notmuch restore) is executed, a new set of
   flags based on the tags is constructed for every message and a new
   file name is prepared based on the old file name but with the new
   flags. If the flags differs and the old message was in 'new'
   directory then this is replaced with 'cur' in the new file name. If
   the new and old file names differ, the file is renamed and notmuch
   database is updated accordingly.

   The rename happens before the database is updated. In case of crash
   between rename and database update, the next run of notmuch new
   brings the database in sync with the mail store again.

c5416b6f1b notmuch new: Fix to work on filesystems returning DT_UNKNOWN
Such as reiserfs or xfs. This has been broken since the merge of
support for rename and deletion of files from the mail store.

Here's the original justification for the patch:

A review of notmuch-new.c shows three uses of ->d_type:

Near line 153, in _entries_resemble_maildir() we can simply allow for
DT_UNKNOWN. This would fail if people have MH-style folders which have
three folders called "new" "cur" and "tmp", but that seems unlikely, in
which case the "tmp" folder would simply not be scanned.

Near line 273 in add_files_recursive() we have another check. If
DT_UNKNOWN, we fall through, then add_files_recursive() does a stat
almost immediately, returning with success if the path isn't a
directory.

Thus, the fallback is already written.

Finally, near line 343, in add_files_recursive() (a long function) we
have another check. Here we can simply treat DT_UNKNOWN as DT_LNK, since
the logic for the stat() results are the same.

c340c1bd11 notmuch new: Print upgrade progress report as a percentage.
Previously we were printing a number of messages upgraded so far. The
original motivation for this was to accurately reflect the fact that
there are two passes, (so each message is processed twice and it's not
accurate to represent with a single count). But as it turns out, the
second pass takes zero time (relatively speaking) so we're still not
accounting for it.

If nothing else, the percentage-based reporting makes for a cleaner
API for the progress_notify function.

c485c51585 notmuch new: Don't prevent database upgrade from being interrupted.
Our signal handler is designed to quickly flush out changes and then
exit. But if a database upgrade is in progress when the user
interrupts, then we just want to immediately abort. We could do
something fancy like add a return value to our progress_notify
function to allow it to tell the upgrade process to abort. But it's
actually much cleaner and robust to delay the installation of our
signal handler so that the default abort happens on SIGINT.

21f8fd6967 notmuch new: Fix deletion support to recurse on removed directories.

1a38cb841c notmuch new: Never ask the database for any names from a new directory.
When we know that we are adding a new directory to the database, (and
we therefore are using inode rather than strcmp-based sorting of the
filenames), then we *never* want to see any names from the
database. If we get any names that could only make us inadvertently
remove files that we just added.

Since it's not obvious from the Xapian documentation whether new terms
being added as part of new documents will appear in the in-progress
all-terms iteration we are using, (and this might differ based on
Xapian backend and also might differ based on how many new directories
are added and whether a flush threshold is reached).

For all of these reasons, we play it safe and use NULL rather than a
real notmuch_filenames_t iterator in this case to avoid any problem.

7d8271dd9d notmuch new: Fix bug resulting in file removal on initial build of database.
The bug here was that we would see that the database did not know
anything about a directory so would get results from the filesystem in
inode rather than strcmp order.

However, we wouldn't actually ask for the list of files from the
database until after recursing into the sub-directories. So by the
time we traverse the filenames looking for deletions, the database
*does* have entries and we end up detecting erroneous deletions
because our filename list from the filesystem isn't in strcmp order.

So ask for the list of names from the database before doing any
additions to avoid this problem.

59c09623c8 notmuch new: Fix to detect deletions of names at the end of the list.
Previously we only scanned the list of filenames in the filesystem and
detected a deletion whenever that scan skipped a name that existed in
the database. That much was fine, but we *also* need to continue
walking the list of names from the database when the filesystem list
is exhausted.

Without this, removing the last file or directory within any
particular directory would go undetected.

39e81ca431 notmuch new: Fix regression preventing addition of symlinked mail files.
As described in the previous commit message, we introduced multiple
symlink-based regressions in commit
3df737bc4addfce71c647792ee668725e5221a98

Here, we fix the case of symlinks to regular files by doing an extra
stat of any DT_LNK files to determine if they do, in fact, link to
regular files.

49f09958df notmuch new: Fix regression preventing recursion through symlinks.
In commit 3df737bc4addfce71c647792ee668725e5221a98 we switched from
using stat() to using the d_type field in the result of scandir() to
determine whether a filename is a regular file or a directory. This
change introduced a regression in that the recursion would no longer
traverse through a symlink to a directory. (Since stat() would resolve
the symlink but with scandir() we see a distinct DT_LNK value in
d_type).

We fix this for directories by allowing both DT_DIR and DT_LNK values
to recurse, and then downgrading the existing not-a-directory check
within the recursion to not be an error. We also add a new
not-a-directory check outside the recursion that is an error.

3fa2385f7c notmuch new: Proper support for renamed and deleted files.
The "notmuch new" command will now efficiently notice if any files or
directories have been removed from the mail store and will
appropriately update its database.

Any given mail message (as determined by the message ID) may have
multiple corresponding filenames, and notmuch will return one of
them. When a filen is deleted, the corresponding filename will be
removed from the message in the database. When the last filename is
removed from a message, that message will be entirely removed from the
database.

All file additions are handled before any file removals so that rename
is supported properly.

2e96464f97 notmuch new: Store detected removed filenames for later processing.
It is essential to defer the actual removal of any filenames from the
database until we are entirely done adding any new files. This is to
avoid any information loss from the database in the case of a renamed
file or directory.

Note that we're *still* not actually doing any removal---still just
printing messages indicating the filenames that were detected as
removed. But we're at least now printing those messages at a time when
we actually *can* do the actual removal.

03d5175001 notmuch new: Detect deleted (renamed) files and directories.
This takes advantage of the notmuch_directory_t interfaces added
recently (with cooresponding storage of directory documents in the
database) to detect when files or entire directories are deleted or
renamed within the mail store.

This also fixes the recent regression where *all* files would be
processed by every run of "notmuch new", (now only new files are
processed once again).

The deleted files and directories are only detected so far. They
aren't properly removed from the database.

2a98b1d487 add_files_recursive: Make the maildir detection more efficient.

28ce73848d add_files_recursive: Separate scanning for directories and files for legibility.
We now do two scans over the entries returned from scandir. The first
scan is looking for directories (and making the recursive call). The
second scan is looking for new files to add to the database.

This is easier to read than the previous code which had a single loop
and some if statements with ridiculously long bodies. It also has the
advantage that once the directory scan is complete we can do a single
comparison of the filesystem and database mtimes and entirely skip the
second scan if it's not needed.

2c4555f1a5 notmuch new: Remove an unnecessary stat of every regular file in the mail store.
We were previousl using the stat for two reasons. One was to obtain
the mtime of the file. This usage was removed in the previous commit,
(since the mtime is unreliable in the case of a file being moved into
the mail store).

The second reason was to identify regular and directory file
types. But this information is already available in the result we get
from scandir.

What's left is simply a stat for each directory in the mailstore,
(which we are still using to compare filesystem mtime with the mtime
stored in the database).

dde214c768 notmuch new: Eliminate the check on the mtime of regular files before adding.
This check was buggy in that moving a pre-existing file into the mail
store, (where the file existed before the last run of "notmuch new"),
does not update the mtime of the file. So the message would never be
added to the database.

The fix here is not practical in the long run, (since it causes *all*
files in the mail store to be processed in every run of "notmuch new"
(!)). But this change will let us drop a stat() call that we don't
otherwise need and will help move us toward proper database-backed
detection of new files, (which will fix the bug without the
performance impact of the current fix).

29908b9f13 notmuch new: Avoid updating directory timestamp if interrupted.
This was a very dangerous bug. An interrupted "notmuch new" session
would still update the timestamp for the directory in the

to the original interruption *never* being picked up by future runs of
"notmuch new". Yikes!

reported by stat() such as a missing file or insufficient privilege,
we can simply ignore and skip the file. For the others, such as a fault

24ae7718b7 notmuch-new: Test if directory looks like Maildir before skipping tmp.
'notmuch new' skips directory entries with the name 'tmp'. This is to
prevent notmuch from processing possibly incomplete Maildir messages
stored in that directory.

This patch attempts to refine the feature. If "tmp" entry is found,
it first checks if the containing directory looks like a Maildir
directory. This is done by searching for other common Maildir
subdirectories. If they exist and if the entry "tmp" is a directory
then it is skipped.

Files and subdirectories with the name "tmp" that do not look like
Maildir will still be processed by 'notmuch new'.

d024ab4a04 ANSI escapes in "new" only when output is a tty
When running "notmuch new --verbose", ANSI escapes are used. This may not be

5fdce046a1 Support for printing file paths in new command
For very large mail boxes, it is desirable to know which files are being
processed e.g. when a crash occurs to know which one was the cause. Also,
it may be interesting to have a better idea of how the operation is
progressing when processing mailboxes with big messages.

This patch adds support for printing messages as they are processed by
"notmuch new":

* The "new" command now supports a "--verbose" flag.

* When running in verbose mode, the file path of the message about to be
  processed is printed in the following format:

    current/total: /path/to/message/file

  Where "current" is the number of messages processed so far and "total" is
  the total count of files to be processed.

  The status line is erased using an ANSI sequence "\033[K" (erase current
  line from the cursor to the end of line) each time it is refreshed. This
  should not pose a problem because nearly every terminal supports it.

* The signal handler for SIGALRM and the timer are not enabled when running
  in verbose mode, because we are already printing progress with each file,
  periodical reports are not neccessary.
