Reduce the verbosity of the progress indicator.
It's fast enough that we can wait for 1000 messages before updating.
Carl Worth [Thu, 15 Oct 2009 00:25:20 +0000 (17:25 -0700)]
Add support for message-part mime parts.
We could (and probably should) reparse and index all the headers from
the embedded message, but I'm not choosing to do that now---I'm just
indexing the body of the embedded message.
Carl Worth [Thu, 15 Oct 2009 00:24:28 +0000 (17:24 -0700)]
Avoid segfault on message with no subject.
It's fun how turning a program loose on 500,000 messages will find
lots of littel corner cases.
Carl Worth [Thu, 15 Oct 2009 00:10:14 +0000 (17:10 -0700)]
Add some sort of progress indicator.
It's nice to let the user know that something is happening.

Document the little details separating the sup and notmuch indexes.
As can be seen here, there are not a lot of differences. I've verified
this by using sup-sync to import a month of mail from the sup mailing
list, and comparing the database term-by-term, value-by-value, and
data-by-data with that created by notmuch. There are no differences
other than those documented here.
Carl Worth [Wed, 14 Oct 2009 23:38:21 +0000 (16:38 -0700)]
Avoid trimming initial whitespace while looking for signatures.
I ran into a message with an indented stack trace that my indexer
was mistaking for a signature.
Carl Worth [Wed, 14 Oct 2009 23:35:03 +0000 (16:35 -0700)]
Index an attachment's filename extension as well.
I hadn't realized that sup used a special term for this. But there
you go.
Carl Worth [Wed, 14 Oct 2009 23:28:07 +0000 (16:28 -0700)]
Index the filename of any attachment.

[sup-compat] Don't index mime parts with content-disposition of attachment
Here's another change which I'm making for sup compatibility against
my better judgment. It seems that sup never indexes content from
mime parts with content-disposition of attachment. But these
attachments are often very indexable, (for example, the first one
I encountered was a small shell script).
So I'll have to think a bit about whether or not I want to revert
this commit. To do this properly we would really want to distinguish
between attachments that are indexable, (such as text), and those
that aren't, (such as binaries). I know the mime-type alone isn't
alwas sufficient here as even this little plaintext shell script
was attached as octet-stream.
And if we wanted to get really fancy we could run things like antiword
to generate text from non-text attachments and index their output.
Carl Worth [Wed, 14 Oct 2009 23:18:17 +0000 (16:18 -0700)]
Add label "attachment" when an attachment is seen.
Carl Worth [Wed, 14 Oct 2009 23:04:25 +0000 (16:04 -0700)]
Split thread_id value on commas before inserting into hash.
One thread_id value may have multiple thread IDs in it so we need
to separate them out before inserting into our hash.
Carl Worth [Wed, 14 Oct 2009 22:55:07 +0000 (15:55 -0700)]
Add missing null terminator before using byte-array contents as string.
Thanks to valgrind for spotting this one.
Carl Worth [Wed, 14 Oct 2009 22:33:16 +0000 (15:33 -0700)]
notmuch-index-message: Add explicit support for multipart mime.
Instead of using the recursive "foreach" method, we implement our
own recursive function. This allows us to ignore the signature
component of a multipart/signed message, (which we certainly
don't need to index).
Carl Worth [Wed, 14 Oct 2009 21:06:06 +0000 (14:06 -0700)]
[sup-compat] Don't trim trailing whitespace on line introducing quotation.
Ignoring this whitespace seems like a good idea to me, but it's
interfering with my comparisons with sup since sup doesn't do this.
This might be a commit worth dropping in the future since it exists
only for pedantic consistency with sup and not for any reason of its
own.
Carl Worth [Wed, 14 Oct 2009 21:00:10 +0000 (14:00 -0700)]
notmuch-index-message: Fix handling of thread_id terms.
We now emit one term per thread_id, rather than the comma-separated
super-term we were doing previously.
Carl Worth [Wed, 14 Oct 2009 20:46:01 +0000 (13:46 -0700)]
notmuch-index-message: Use local-part of email addres in lieu of name.
If there's no name given, take the portion of the email addres
before the '@' sign.
One step closer to matching sup's terms in the database.
Carl Worth [Wed, 14 Oct 2009 20:30:33 +0000 (13:30 -0700)]
Use gmime's own reference-parsing code.
Here's another instance where I "knew" gmime must have support for
some functionality, but not finding it, I rolled my own. Now that
I found g_mime_references_decode I'm glad to drop my ugly code.
Carl Worth [Wed, 14 Oct 2009 19:48:58 +0000 (12:48 -0700)]
notmuch-index-message: Correctly parse and index encoded mime parts.
This cleans up some old code that was very ugly, (separately opening
the mail file and seeking to the end of the headers to parse the
body). I knew gmime must have had support for transparently decoding
mime content, but I just couldn't find it previously.
Note: Multipart and MultipartSigned parts are not handled yet.
Things are quite happy now. The few differences I see with sup are:
1. sup forces email address domains to lowercase, (I don't think I care)
2. sup and notmuch disagree on ordering of multiple thread_id values
(another thing that's of no concern)
We are still doing one thing wrong when a message belongs to multiple
threads. We've got a nice comma-separated thread-value just like sup,
but then we're also putting in a comma-separated thread-term where
sup does multiple thread terms. That should be an easy fix.
Beyond that, sup and notmuch are still disagreeing on the term lists
for some messages, (I think attachment vs. inline content-disposition
is at least one piece of this). But there are likley still differences
in the heuristics for which chunks of the message body to index. I'll
be looking into this more.

notmuch-index-message: Lookup children for thread_id as well.
This provides the thread_id linkage for when a child message is
indexed before the parent.

notmuch-index-message: Use more meaningful variable names.
The abuse of the generic "value" name was getting very hard to read.
Carl Worth [Wed, 14 Oct 2009 16:54:05 +0000 (09:54 -0700)]
notmuch-index-message: Start generating correct thread_id values.
Currently we're looking up all parents (based on In-reply-to and
References header) and using the list of all thread_id values
from those as our thread_id value. We're missing one step which
sup does which is to also look up any children in the database
that have reference our message ID. So we'll need to do that next.
Carl Worth [Wed, 14 Oct 2009 15:02:27 +0000 (08:02 -0700)]
Factor out parsing of reference-header values and pickup In-reply-to.
This is in preparation for doing a couple of passes over the references,
(one to add terms to the database, and a second to find the thread_id).
We also now parse the In-reply-to header which we were missing before.
We treat it identically to the References header.

Getting more sup-compatible all the time.

notmuch-index-message: Avoid crashing when a message has no references.
It's obviously an innocent-enough message, and the right thing is
so easy to do.

notmuch-index-message: Read message filenames from stdin
This allows for indexing an arbitrary number of messages with a
single invocation rather than just a single message on the command
line.

Move index_file out from main() into its own function.
This is a step toward having a program that will index many messages
with a single invocation.

notmuch-index-message: Index References as well.
We're basically matching sup now! (As long as one uses sup with my
special notmuch_index.rb file).

Minor code re-ordering for clarity.
Pull the "constant" source_id value out from among several calls
that set a value based on the Message ID.

notmuch-index-message: Don't index the line introducing a quote.
We identify it based on a trailing ':' on the line before a quote
begins.
At this point the database-dump diff between sup and notmuch is
getting very, very small, (at least for our one test message).

notmuch-index-message: Don't index quoted lines and signatures.
At this point, we're achieving a result that is *very* close to
what sup does. The only difference is that we are still indexing
the "excerpts from message ..." line, and we are not yet indexing
references.

notmuch-index-message: Add code to actually create a Xapian index
Most of this code is fairly clean and works well. One part is
fairly painful---namely extracting the body of an email message
from libgmime. Currently, I'm just extracting the offset to
the end of the headers, and then separately opening the message.
Surely there's a better way.
Anyway, with that the results are looking very similar to sup-sync
now, (as verified by xapian-dump). The only substantial difference
I'm seeing now is that sup does not seem to index quoted portions
of messages nor signatures. I'm not actually sure whether I want
to follow sup's lead in that or not.

xapian-dump: Add a little mor indentation
Just to make it easier to visually identify where one document ends

Carl Worth [Tue, 13 Oct 2009 20:18:32 +0000 (13:18 -0700)]
Include document data in the dump.
At the same time, I've started hacking up sup with a new NotmuchIndex
class in the place of the previous XapianIndex class. The new class
stores only the source_info field in the document data, (rather than
a serialized ruby hash with a bunch of data that can be found in the
original message).
Eventually, I plan to replace source_info with a relative filename for
the message, (or even a list of filenames for when multiple messages
in the database share a common message ID).

xapian-dump: Add support to unserialize values.
The interface for this is cheesy, (bare integer value numbers on the
command line indicating that unserialization is desired for those
value numbers). But this at least lets us print sup databases with
human-readable output for the date values.

Add sup-compatible prefixes and achieve sup-compatible print output
What I've done here is to instrument sup-sync to print the text
and terms objects it constructs just before indexing a message.
Then I've made my g_mime_test program achieve (nearly) identical
output for an example email message, (just missing the body
text). Next we can start shoving this data into a Xapian index.

Initial commit of a test program to form the basis of notmuch.
