As discussed in the thread starting at [1], the fully qualified domain
name is a bit tricky to get reproducibly, might reveal information
people prefer to keep private, and somewhat unlikely to provide
reliable mail routing.
The new approach of $current_username@localhost is better for the
first two considerations, and probably at least as good as a test mail
address.

notmuch release 0.32.3-1 for unstable (sid) [dgit]
[dgit distro=debian no-split --quilt=linear]
|
|
This fixes the bug id:87bl9lx864.fsf@kisara.moe
|
|
Notmuch 0.32 corresponds to libnotmuch 5.4 as indicated by docstrings;
however, the minor number wasn't bumped. Any libnotmuch downstream
consumer using the LIBNOTMUCH_CHECK_VERSION macro to support multiple
versions won't be able to access the new 5.4 functions.

Both notmuch_database_open() and notmuch_database_open_verbose()'s
documentation state they call notmuch_database_open_with_config() with
config_path=NULL; however, their implementations pass an empty string.
The empty string is the correct value to maintain their original
behavior of not loading the user's configuration so their documentation
is incorrect.
|
|
Partly this is to recognize the semantics we inherit from Xapian,
partly to mention the new autocommit feature.
|
|
This change addresses two known issues with large sets of changes to
the database. The first is that as reported by Steven Allen [1],
notmuch commits are not "flushed" when they complete, which means that
if there is an open transaction when the database closes (or e.g. the
program crashes) then all changes since the last commit will be
discarded (nothing is irrecoverably lost for "notmuch new", as the
indexing process just restarts next time it is run). This does not
really "fix" the issue reported in [1]; that seems rather difficult
given how transactions work in Xapian. On the other hand, with the
default settings, this should mean one only loses less than a minutes
worth of work. The second issue is the occasionally reported "storm"
of disk writes when notmuch finishes. I don't yet have a test for
this, but I think committing as we go should reduce the amount of work
when finalizing the database.

This will be used to control how often atomic transactions are
committed.
|
|
Unfortunately, it doesn't make a difference if we call
cancel_transaction or not, all uncommited changes are discarded if
there is an open (unflushed) transaction.
|
|
The spacing of the declaration was wrong in ea30110.

Since most memory allocation is (ultimately) in the talloc context
defined by a notmuch_database_t pointer, this gives a more complete
view of memory still allocated at program shutdown.
We also change the talloc report in notmuch.c to mode "a" to avoid
clobbering the newly reported log.
|
|
This commit fixes a small memory leak (per iterator restart) by
actually using the talloc context intended to be blown away on
restart.
|
|
'message' should always be initialized if we reach here, but in case it
is not, we still want to be able to log an error message.
|
|
They are not used outside their file, so being extern seems like an oversight
|
|
This will simplify filtering these message, e.g. in the test suite.
|
|
|
|
This prevents the message document getting multiple thread-id terms
when there are multiple files with the same message-id.
This change shifts some thread ids, requiring adjustments to other tests.

Although this default worked for "notmuch config get", it didn't work
most other places. Restore the previous functionality, with the
wrinkle that XDG locations will shadow $HOME/mail if they exist.
This fixes a bug reported by Jack Kamm in id:87eeefdc8b.fsf@gmail.com

|
This table is intended to be immutable
|
|
Work towards the goal of concurrent access to different Xapian
databases from the same process.
|
|
In principle this could be done without depending on C++11 features,
but these features should be available since gcc 4.8.1, and this
localized usage is easy to replace if it turns out to be problematic
for portability.
|
|
In some uses of reopen, new documents and threads maybe have been
added, and e.g. compaction may have changed the uuid.
|
|
This makes the treatment of relative paths consistent between the
database and config files.
|
|
Prior to 0.32, notmuch had the (undocumented) behaviour that it
expanded a relative value of database.path with respect to $HOME. In
0.32 this was special cased for database.path but broken for
database.mail_root, which causes problems for at least notmuch-new
when database.path is set to a relative path.
The change in T030-config.sh reflects a user visible, but hopefully
harmless behaviour change; the expanded form of the paths will now be
printed by notmuch config.
|
|
This (obvious) bug was caused by cut&pasting the code from
notmuch-config.c into the library and adding on a return at the end.
|
|
When compat canonicalize_file_name was introduced, it was limited to
C code only because it was used by C code only during that time.
>From 5ec6fd4d, (lib/open: check for split configuration when creating
database., 2021-02-16), lib/open.cc, which is C++, relies on the
existent of canonicalize_file_name.
However, we can't blindly enable canonicalize_file_name for C++ code,
because different implementation has different additional signature for
C++ and users can arbitrarily add -DHAVE_CANONICALIZE_FILE_NAME=0 to
{C,CXX}FLAGS.
Let's move our implementation into a util library.

Ignoring this return value seems like a bad idea in general, and in
particular it has been hiding one or more bugs related to handling
long directory names.

This is intended to fix the slow behaviour of "notmuch new" (and possibly
"notmuch reindex") when large numbers of files are deleted.
The underlying issue [1] seems to be the Xapian glass backend spending
a large amount of time in db.has_positions when running queries with
large-ish amounts of unflushed changes.
This commit removes two uses of Xapian queries [2], and replaces them with
an approximation of what Xapian would do after optimizing the
queries. This avoids the calls to has_positions (which are in any case
un-needed because we are only using boolean terms here).
[1] Thanks to "andres" on IRC for narrowing down the performance
bottleneck.
[2] Thanks to Olly Betts of Xapian fame for talking me a through a fix
that does not require people to update Xapian.

Since the library searches in several locations for a config file, the
caller does not know which of these is chosen in the usual case of
passing NULL as a config file. This changes provides an API for the
caller to retrieve the name of the config file chosen. It will be
tested in a following commit.
|
|
Eventually we want to do all opening of databases in the top
level (main function). This means that detection of missing databases
needs to move out of subcommands. It also requires updating the
library to use the new NO_DATABASE status code.
|
|
This will allow more precise return values from various open related functions.
|
|
notmuch_config_open will be preserved in the medium term for use by
the commands that are manipulating the config file directly (config
and setup)
|
|
This matches functionality in the the CLI function
notmuch_config_get_database_path, which was previously used in the CLI
code for all calls to open a database.
|
|
This is mainly copying code from the CLI into the lib. The CLI copy
will be deleted in a later commit.
|
|
This just copies code from from the CLI into the library. New test
infrastructure is needed because apparently we have never tested this
code path.
|
|
The layer of shims here seems a bit wasteful compared to just calling
the corresponding string map functions directly, but it allows control
over the API (calling with notmuch_database_t *) and flexibility for
future changes.
|
|
This is to support the less common (at least in the notmuch codebase)
case of accessing a ;-delimited list config value with an arbitrary
string key.
|
|
This is mainly targetted at notmuch-config.c, or similar applications
that don't necessarily need both a configuration file and a database
to exist.
|
|
Although this increases code duplication, it also increases
flexibility in handling various combinations of missing config file
and missing database.
|
|
|
|
_trial_open can't know if the PATH_ERROR return value will cause the
error message to be returned from the library, so it's up the caller
to clean up if not.
|
|
Like the hook directory, we primarily need a way to communicate this
directory between various components, but we may as well let the user
configure it.
Most of the diff is generalizing choose_hook_dir to work for both
backup and hook directories.
|
|
Choose sibling directory of xapian database, as .notmuch may not
exist.
libgen.h is already used in debugger.c, so it is not a new dependency
/ potential portability problem.
|
|
This promotes _choose_xapian_path from static to extern linkage in
order to share between open.cc and database.cc.
|
|
This changes some error reporting, either intentionally by reporting
the highest level missing directory, or by side effect from looking in
XDG locations when given null database location.
|
|
The main functionality will be tested when notmuch-new is converted to
support split configuration. Here only the somewhat odd case of split
mail root which is actually symlinked to the database path is tested.
|
|
Introduce a new configuration value for the mail root, and use it to
locate mail messages in preference to the database.path (which
previously implied the mail messages were also in this location.
Initially only a subset of the CLI is tested in a split
configuration. Further changes will be needed for the remainder of the
CLI to work in split configurations.
|
|
This is a bit heavyweight for now, but it will make more sense when we
check multiple locations for the Xapian database.
