Today the only thing that prevents public-inbox not reusing the

numbers of deleted messages.
Reusing the message numbers of existing messages is a problem because
if a client ever sees messages that are subsequently deleted the
client will not see the new messages with their old numbers.
In practice this is difficult to trigger because it requires the most
recently added message to be removed and have the removal show up in a
separate pull request. Still it can happen and it should be handled.

While playing with git fast export I discovered that mixing <> and

using sysread in ProcessPipe instead of plain read.
If it is desirable to use readline I can't see how using sysread
can work as readline to be efficient needs to use buffered I/O.

This also makes public-inbox more approachable for light hacking as

The way this is done is to add a method to SearchIdx called index_text
that wraps the call of the term generator method index_text. The new
index_text method takes care of calling both index_text and
increase_termpos (the two functions that are responsible for position
data).
Then index_users, index_diff_inc, index_old_diff_fn, index_diff,
index_body are made proper methods that calls the new index_text.

need to call increase_termpos as well.

had a time zone that was not 4 digits long. This time zone had been
passed straight from the Date line in the email into the author line

The query planner in sqlite3 < 3.8 is not very clever, so when it sees
num mentioned in the query filter, it decides not to use the fast idx_ts

sqlite-3.7, so loading the http landing page of a very large archive

selectid = 0
order = 0
from = 0
detail = SEARCH TABLE over USING INDEX sqlite_autoindex_over_1 (num>?) (~250000 rows)
However, if we slightly tweak the query per SQlite recommendations [1]
by adding + to the num filter, we force it to use the correct index
and see much faster performance:
$ time sqlite3 -line over.sqlite3 'SELECT ts,ds,ddd FROM over \
WHERE +num > 0 ORDER BY ts DESC LIMIT 1000;' > /dev/null
real 0m0.007s

order = 0
from = 0
detail = SCAN TABLE over USING INDEX idx_ts (~
1464303 rows)

running into this issue.
