2021-12-04python-cffi: switch to notmuch_database_{open,create}_with_configDavid Bremner
Since release 0.32, libnotmuch provides searching for database and configuration paths. This commit changes the python module notmuch2 to use those facilities. This fixes the bug reported in [1], along with a couple of the deprecation warnings in the python bindings. Database.default_path is deprecated, since it no longer faithfully reflects what libnotmuch is doing, and it is also no longer used in the bindings themselves. This commit choose the default of config=CONFIG.EMPTY (equivalent to passing "" to notmuch_database_open_with_config). This makes the change upward compatible API-wise (at least as far as the test suite verifies), but changing the default to CONFIG.SEARCH would probably be more convenient for bindings users.

2021-12-04test: add known broken tests for python bindings in split configsDavid Bremner
This reproduces the bug(s) reported in id:87h7d4wp6b.fsf@tethera.net
2021-12-04test: add python-cffi bindings to path for test_pythonDavid Bremner
This will allow testing the new python bindings using test_python, in addition to the current invocation of pytest.
2021-12-03lib/config: don't overwrite database.path if the caller passed itDavid Bremner
If the user passed a path, and we opened it, then we consider that definitive definition of "database.path". This makes libnotmuch respond more gracefully to certain erroneous combinations of NOTMUCH_CONFIG settings and config file contents.
2021-12-03test: add known broken test for conflict with database parameterDavid Bremner
This is arguably user error: having configuration file with bad settings in it (and/or having a bad NOTMUCH_CONFIG environment variable). On the other hand returning a different path than was actually opened is definitely a bug.
2021-12-03test/libconfig: use 'export' for remaining sets of NOTMUCH_CONFIGDavid Bremner
It makes the tests easier to understand if we always use export for environment variables.
2021-10-30lib/load_config: deallocate / NULL database on fatal errorDavid Bremner
This fixes a potential memory leak, and makes the behaviour of notmuch_database_load_config (somewhat) consistent with n_d_{open,create} with config.
2021-10-30lib/load_config: document expectations for db on error, add testsDavid Bremner
This is a bit different than n_d_{open,create}_with_config, since there are several non-zero status codes where we do want to return a non-NULL database structure.
2021-10-30lib/create: fix memory leak, ensure *database=NULL on errorDavid Bremner
This code previously relied on _finish_open to free the notmuch struct on errors (except for the case of database == NULL, which was a potential double free). When we removed those frees from _finish_open, we introduced a (small) memory leak. In this commit, fix the memory leak, and harmonize the on-error behaviour with n_d_open_with_config.
2021-10-30lib/create: document expectations for db on error, add testsDavid Bremner
It seems sensible to harmonize the behaviour with n_d_open_with_config. In this commit we just assert the desired behaviour.
2021-10-30lib/open: fix potential double-free, ensure *database=NULL on errorDavid Bremner
During refactoring for 0.32, the code that set notmuch=NULL on various errors was moved into _finish_open. This meant that the the code which relied on that to set *database to NULL on error was no longer correct. It also introduced a potential double free, since the notmuch struct was deallocated inside _finish_open (via n_d_destroy). In this commit we revert to "allocator frees", and leave any cleanup to the caller of _finish_open. This allows us to get back the behaviour of setting *database to NULL with a small change. Other callers of _finish_open will need free notmuch on errors.
2021-10-30test: add two known broken tests for missing config filesDavid Bremner
The documentation claims that the database will be set to NULL in this case, but it is currently not happening. Based on a reproducer [1] from Austin Ray. [1]: id:20211021190401.imirxau2ewke6e2m@athena
2021-10-27test/libconfig: use 'export' when restoring NOTMUCH_CONFIGDavid Bremner
This is required when NOTMUCH_CONFIG has been unset, and is harmless otherwise.

2021-09-29test/T355-smime: Use key as exported by gpgsmDavid Bremner
As reported in id:87h7pxiek3.fsf@tethera.net, the previous version of the test is flaky. There is some so-far undebugged interaction between openssl and gpgsm that causes the keys to fail to import. As a potential workaround, use the key as exported by gpgsm, and eliminate openssl from this particular pipeline.
2021-09-11test/emacs: tests for notmuch-{tree,unthreaded} with bad CWDDavid Bremner
These work thanks to the previous wrapping of process creation primitives.
2021-09-11emacs: wrap call-processDavid Bremner
Provide safe working directory
2021-09-11test/emacs: test for notmuch-show with nonexistent CWDDavid Bremner
Somewhat predictably, the other code path in notmuch-call-notmuch--helper also needs to be fixed.
2021-09-11emacs: wrap make-processDavid Bremner
Provide a safe working directory.
2021-09-11test/emacs: test for notmuch-search with nonexistent CWDDavid Bremner
(At least) notmuch-start-notmuch needs to be updated to set a safe working directory.
2021-09-11emacs: wrap call-process-regionDavid Bremner
As with notmuch--process-lines, initial purpose is to provide a safe binding for default-directory. This is enough to make notmuch-hello robust against non-existent or corrupt values default-directory, but probably not other views.
2021-09-11test/emacs: run notmuch-hello with a nonexisting default dirDavid Bremner
This replicates the problem reported in Debian bug #922536.
2021-09-11test/emacs: provide macro test-log-errorDavid Bremner
Because of the way emacs reports errors, a test form can crash and not change the main buffer. To work around this, capture both signalled errors and any other messages.

notmuch 0.33.1 release
2021-09-10lib: use 'localhost' rather than fqdn for default mail address.David Bremner
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. [1]: id:87sfyibqhj.fsf@tethera.net
2021-09-08test/emacs: test for functions in notmuch-search-result-format.David Bremner
Based on the commit message in id:20210221151902.2301690-3-dme@dme.org Add the function notmuch-test-result-flags to test-lib.el to avoid repeating it in 3 T*.sh files.
2021-09-04CLI/tag: enable sexp queriesDavid Bremner
We have to rewrite _optimize_tag_query here because it is generating a query string in the infix Xapian syntax. Luckily this is easy to do with the sexp query syntax.
2021-09-04CLI/{count, dump, reindex, reply, show}: enable sexp queriesDavid Bremner
The change in each case is to call notmuch_query_create_with_syntax, relying on the already inherited shared options. As a bonus we get improved error handling from the new query creation API. The remaining subcommand is 'tag', which is a bit trickier.
2021-09-04lib/parse-sexp: apply macrosDavid Bremner
Macros implement lazy evaluation and lexical scope. The former is needed to make certain natural constructs work sensibly (e.g. (tag ,param)) but the latter is mainly future-proofing in case the DSL is is extended to allow local bindings. For technical background, see chapters 6 and 17 of [1] (or some other intermediate programming languages textbook). [1] http://cs.brown.edu/courses/cs173/2012/book/
2021-09-04lib/parse-sexp: support saved s-expression queriesDavid Bremner
It turns out there is not really much code in query-fp.cc useful for supporting the new syntax. The code we could potentially factor out amounts to calling notmuch_database_get_config; both the key construction and the parsing of the results are specific to the query syntax involved.
2021-09-04CLI/config support saving s-expression queriesDavid Bremner
This commit does not enable using saved s-expression queries, only saving and retrieving them from the config file or the database. Use in queries will be enabled in a following commit.
2021-09-04lib/parse-sexp: handle saved queriesDavid Bremner
This provides functionality analogous to query: in the Xapian QueryParser based parser. Perhaps counterintuitively, the saved queries currently have to be in the original query syntax (i.e. not s-expressions).
2021-09-04lib/parse-sexp: parse user headersDavid Bremner
One subtle aspect is the replacement of _find_prefix with _notmuch_database_prefix, which understands user headers. Otherwise the code mainly consists of creating a fake prefix record (since the user prefixes are not in the prefix table) and error handling.
2021-09-04lib/parse-sexp: support infix subqueriesDavid Bremner
This is necessary so that programs can take infix syntax queries from a user and use the sexp query syntax to construct e.g. a refinement of that query.
2021-09-04lib/parse-sexp: expand queriesDavid Bremner
The code here is just gluing together _notmuch_query_expand with the existing sexp parser infrastructure.
2021-09-04lib/parse-sexp: support regular expressionsDavid Bremner
At least to the degree that the Xapian QueryParser based parser also supports them. Support short alias 'rx' as it seems to make more complex queries nicer to read.
2021-09-04lib/query: generalize exclude handling to s-expression queriesDavid Bremner
In fact most of the code path is in common, only the caching of terms in the query needs to be added for s-expression queries.
2021-09-04lib/parse-sexp: handle unprefixed terms.David Bremner
This is equivalent to adding the same field name "" for multiple prefixes in the Xapian query parser, but we have to explicitely construct the resulting query.
2021-09-04lib/parse-sexp: add '*' as syntactic sugar for '(starts-with "")'David Bremner
Users that insist on using a literal '*' as a tag, can continue to do so by quoting it when searching.
2021-09-04lib/parse-sexp: 'starts-with' wildcard searchesDavid Bremner
The many tests potentially overkill, but they could catch typos in the prefixes table. As a simplifying assumption, for now we assume a single argument to the wildcard operator, as this matches the Xapian semantics. The name 'starts-with' is chosen to emphasize the supported case of wildcards in currrent (1.4.x) Xapian.
2021-09-04lib/parse-sexp: add term prefix backed fieldsDavid Bremner
We use "boolean" to describe fields that should generate terms literally without stemming or phrase splitting. This terminology might not be ideal but it is already enshrined in notmuch-search-terms(7).
2021-09-04lib/parse-sexp: support phrase queries.David Bremner
Anything that is quoted or not purely word characters is considered a phrase. Phrases are not stemmed, because the stems do not have positional information in the database. It is less efficient to scan the term twice, but it avoids a second pass to add prefixes, so maybe it balances out. In any case, it seems unlikely query parsing is very often a bottleneck.
2021-09-04lib/parse-sexp: support subject fieldDavid Bremner
The broken tests are because we do not yet handle phrase searches.
2021-09-04lib/parse-sexp: support and, not, and or.David Bremner
All operations and (Xapian) fields will eventually have an entry in the prefixes table. The flags field is just a placeholder for now, but will eventually distinguish between various kinds of prefixes.
2021-09-04lib/parse-sexp: stem unquoted atomsDavid Bremner
This is somewhat less DWIM than the Xapian query parser, but it has the advantage of simplicity.
2021-09-04lib/parse-sexp: parse single terms and the empty list.David Bremner
There is not much of a parser here yet, but it already does some useful error reporting. Most functionality sketched in the documentation is not implemented yet; detailed documentation will follow with the implementation.
2021-09-04CLI/search+address: support sexpr queriesDavid Bremner
Initially support selection of query syntax in two subcommands to enable testing.
2021-09-04configure: optional library sfsexpDavid Bremner
The configure part is essentially the same as the other checks using pkg-config. Since the optional inclusion of this feature changes what options are available to the user, include it in the "built_with" pseudo-configuration keys.
2021-09-04CLI: make variable n_requested_db_uuid file scope.David Bremner
It turns out that now that we pass an open database into the subcommands, it is easy to check any requested uuid against the database at the same time as we process the other shared arguments. This results in overall less boilerplate code, as well as making a CLI scope function and variable file scope in notmuch.c.
2021-08-30test: known broken test for emacs display of message/rfc822 partsDavid Bremner
There are at least 3 bugs present. 1) notmuch-show-insert-part-message/rfc822 assumes that message/rfc822 parts will have a ":content" property, but that turns out not to be the case. 2) something deep in gnus wants gnus-newsgroup-charset, but that is defined in gnus-sum, which is not loaded by default. 3) If gnus-sum is loaded, then the display of the message/rfc822 part succeeds, but the buffer gets put into gnus-article-mode, which means that, inter alia, notmuch text properties and keybindings get wiped.
