The character set is chosen to be suitable for pathnames, and the same
as that used by contrib/nmbug

This program is used both as a test-bed/unit-tester for
../util/hex-escape.c, and also as a utility in future tests of dump
and restore.

These are more like unit tests, to (try to) make sure the library
functionality is working before building more complicated things on
top of it.

To: notmuch
Add support for batch tagging operations through stdin to "notmuch
tag". This can be enabled with the new --stdin command line option to
"notmuch new". The input must consist of lines of the format:
T +<tag>|-<tag> [...] [--] <search-terms>
Each line is interpreted similarly to "notmuch tag" command line
arguments. The delimiter is one or more spaces ' '. Any characters in
<tag> and <search-terms> MAY be hex encoded with %NN where NN is the
hexadecimal value of the character. Any ' ' and '%' characters in
<tag> and <search-terms> MUST be hex encoded (using %20 and %25,
respectively). Any characters that are not part of <tag> or
<search-terms> MUST NOT be hex encoded.
Leading and trailing space ' ' is ignored. Empty lines and lines
beginning with '#' are ignored.

My issues from v1 still stand. I would rather see some unification with
the existing tag file format, rather than introduce a second format,
with it's increased maintenance burden and confusion to users. Either
that or a more general batch command interface.

The existing dump/restore file format is a dead end. It fails
magnificently with tags and message-ids that have spaces or some other
special characters in them. It doesn't support removal of tags. There's
zero room for extensibility. I can't imagine how that could be used for
notmuch tag.
David originally wrote the dump/restore patches
id:"1324214111-32079-1-git-send-email-david@tethera.net" to add a
"notmuch" format (yes, a second format) in addition to the "sup" format
we currently have, to fix the issues with special characters. That too
lacked features to support batch tagging in notmuch new. The format
proposed here would fix the issues and work with notmuch tag, and it
would be obvious to use for anyone who has used notmuch tag.
I see a general batch command interface overkill. Too many problems to
solve for little gain (see the previous thread for details). What other
notmuch commands than tag would really benefit from it? If you want to
do search or show or whatever, the general batch command interface to
use is /bin/sh.
For notmuch tag, particularly in connection with notmuch new, there's a
clear benefit in having a batch mode: if you have "new" in new.tags, and
do initial tagging on the "new" tagged messages (e.g. in post-new hook),
you don't want anyone messing with the database while you're processing
the messages tagged "new". The batch tagging of this series keeps the db
locked for the duration of such initial tagging.
I'm totally fine with modifying the proposed format (e.g. change "T" to
"tag", make things compatible with a future general batch mode), but to
be absolutely clear: I will not implement a general batch command
mode. If that is deemed to be what is wanted, that's okay too. I can
share my WIP patches for dump/restore, and focus on something else.
BR,
Jani.

I was thinking about the best way of making the interface extensible,
and it might be better have a kind of modal interface, where some well
defined escape at the beginning of the line introduces a mode switch.
This has two apparent advantages: it avoids duplication of redundant
information at the beginning of each line, and for input to a subcommand
it could be optional.
something like
* tag
+foo +bar msg.id@blah
+glub -glog other.msg.id@blog
vs
* restore
foo bar msg.id@blah
glub glog other.msg.id@blog
where a hypothetical general batch interface could take those two files
concatenated together, and the "*" lines would be optional feeding to
tag and restore respectively.
I guess the current proposal is to have the restore format and tag
format a bit closer
* restore
+foo +bar msg.id@blah
+glub +glog other.msg.id@blog
This looks like it would be a 2% space increase for my tags. I guess I
could live with that. Another option would be to have the '+' be
optional for tag as well; I suppose then tags starting with + would be
ambiguous, which is probably a bad idea.

Does it not worry you that such a modal format isn't much fun to filter
with regular command line tools?

Restore currently has two modes of operation: with and without
--accumulate option. How would you specify that *outside* the file, if
the restore was done with the hypothetical general batch interface? And
if there was such an interface, we shouldn't have a dedicated restore
command for restoring such dump files, should we...? (It's useful to be
able to use the same dump file with/without --accumulate. See e.g. [1].)

Something like that... though in my original idea the same dump file
could be fed to either tag or restore. They would interpret the file
using the same routine, but perform the tagging in slightly different
ways (mainly to keep restore very strict as it's a backup/restore
command).

I'd like to keep the new format unambiguous if at all possible.
