2021-04-06CLI/config: remove calls to notmuch_config_open from top levelDavid Bremner
This will allow simplifying the subcommand interface. Change the internal API to notmuch_config_open to not tie it to the implementation of subcommands in notmuch.c. It also fixes a previously broken test, since notmuch_config_open does not understand the notion of the empty string as a config file name.
2021-03-27CLI/config: support set/get with split configurationDavid Bremner
There are two small code changes. The main one is to retrieve the possibly updated config file name found during the database opening call. The second change is to allow empty config file names, as a (currently broken) way of specifying that configuration should only be taken from the database.
2021-03-27lib: provide notmuch_config_pathDavid Bremner
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.
2021-03-27CLI+lib: detect missing database in split configurations.David Bremner
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.
2021-03-27lib: add NOTMUCH_STATUS_NO_DATABASEDavid Bremner
This will allow more precise return values from various open related functions.
2021-03-27CLI/config: default to storing all config in external filesDavid Bremner
Previously the fact that some configuration options were only stored in the database (and thus editing the config file had no effect) was a source of user confusion. This was fixed with the series ending at d9af0af1646. On the other hand, the underlying partition of config options into those stored by default in the database and those stored in the config file remained. This is also confusing, since now some invocations of "notmuch config set" modify the config file, and others silently modify the database instead. With this commit, it is up to the user to decide which configuration to modify. A new "--database" option is provided for notmuch config to enable modifying the configuration information in the database; otherwise the default is to update an external config file.
2021-03-27CLI/config: drop cached data from notmuch_config_tDavid Bremner
The idea is to preserve notmuch_config_t as a thin wrapper for GKeyFile.
2021-03-27CLI/config: drop obsolete notmuch_config_get_*David Bremner
These are no longer used, replaced by notmuch_config_get.
2021-03-27CLI/notmuch: switch notmuch_command to notmuch_config_getDavid Bremner
The goal at this point is to remove the dependence on notmuch_config_get_* without breaking any existing functionality. This is a step towards removing notmuch_config_get_* in a future commit.
2021-03-27CLI/config: use notmuch_database_reopenDavid Bremner
This allows `notmuch config` to use the common configuration information carried by the notmuch_database_t opened at the top level.
2021-03-27CLI/config: migrate notmuch_config_open to new configDavid Bremner
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)
2021-03-27CLI/config: switch "notmuch config list" to merged configDavid Bremner
Use the database opened at the top level rather than opening another notmuch_database_t. Test output changes because keys are now listed in alphabetical order, and because a missing database is no longer an error.
2021-03-27CLI/setup: switch to new configuration frameworkDavid Bremner
Most of the changes are the elimination of notmuch_config_t accessor use. We also migrate some of the diagnostics to the top level where we are opening the files in question.
2021-03-27test/setup: check file output instead of notmuch config listDavid Bremner
This allows verification of comments added to new / updated config file.
2021-03-27CLI/config: use merged config for "config get"David Bremner
This commit starts the conversion of notmuch-config.c functionality (as opposed to just interface) to the new config framework. The change to T030-config is because of the move of the canonicalization database paths from the notmuch_config_t accessor to the internal function _choose_database_path.
2021-03-27CLI: load merged config at top levelDavid Bremner
This paves the way for the conversion of the remaining subcommands to the new configuration framework.
2021-03-27lib/open: canonicalize relative path read from config fileDavid Bremner
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.
2021-03-27lib/config: set default for primary user emailDavid Bremner
This is mainly copying code from the CLI into the lib. The CLI copy will be deleted in a later commit.
2021-03-27lib/config: set defaults for user full nameDavid Bremner
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.
2021-03-27lib/config: add config_pairs iteratorsDavid Bremner
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.
2021-03-27lib/config: add notmuch_config_get_values_stringDavid Bremner
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.
2021-03-27lib: provide notmuch_database_load_configDavid Bremner
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.
2021-03-27lib/open: pull _load_key_file out of _choose_database_pathDavid Bremner
Although this increases code duplication, it also increases flexibility in handling various combinations of missing config file and missing database.
2021-03-27test: convert random-corpus to use n_d_open_with_configDavid Bremner
Remove one more usage of notmuch_config_get_database_path
2021-03-27lib: add missing status stringsDavid Bremner
2021-03-27lib/open: fix leaks calling _trial_openDavid Bremner
_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.
2021-03-20CLI/new: use configuration variable for backup directoryDavid Bremner
The stat is essentially replaced by the mkdir for error detection purposes. This changes the default location for backups to make things tidier, even in non-split configurations. Hopefully there is not too many user scripts relying on the previous location. Because the default location may not exist, replace the use of stat for error detection with a call to mkdir.
2021-03-20lib/config: add configuration variable for backup directoryDavid Bremner
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.
2021-03-20lib/open: fix hook directory calculation in split configurationDavid Bremner
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.
2021-03-20lib/compact: enable split configDavid Bremner
This promotes _choose_xapian_path from static to extern linkage in order to share between open.cc and database.cc.
2021-03-20CLI/insert: support split database and mail rootDavid Bremner
The new test is in T055-path-config because it uses the helper function split_config, and because it seems easier to put the database path related tests in one place.
2021-03-20lib/open: support XDG_DATA_HOME as a fallback database location.David Bremner
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.
2021-03-20CLI/new: support split database and mail locationDavid Bremner
This adds new state variable for the mail root, and uses it most places db_path was used. The notable exception is dumps from backups. The latter will be dealt with properly in a future commit.
2021-03-20lib/open: check for split configuration when creating database.David Bremner
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.
2021-03-20lib: support splitting mail from database location.David Bremner
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.
2021-03-20lib/open: Use check for existing database by trial openingDavid Bremner
This is a bit heavyweight for now, but it will make more sense when we check multiple locations for the Xapian database.
2021-03-20lib/open: use _finish_open in n_d_create_with_configDavid Bremner
This avoids reading the configuration file twice.
2021-03-20lib/open: factor out the second half of n_d_open_with_configDavid Bremner
The idea is to allow reuse in n_d_create_with_config. This is primarily code movement, with some changes in error messages to reduce the number of input parameters.
2021-03-20lib/open: reuse directory checks from n_d_c_with_configDavid Bremner
Make checks more uniform between creating new databases and opening existing ones.
2021-03-20lib/open: factor out library initializationDavid Bremner
This is slightly more tidy, but more importantly it allows for re-use of this code in n_d_create_with_config. That re-use will be crucial when we no longer call n_d_open_with_config from n_d_create_with_config.
2021-03-20lib: remove "path" from notmuch structDavid Bremner
This removes duplication between the struct element and the configuration string_map entry. Create a simple wrapper for setting the database path that makes sure the trailing / is stripped.
2021-03-20lib/open: allocate notmuch_t struct earlyDavid Bremner
This gives more flexibility in restructuring the database opening code.
2021-03-19lib/open: support NOTMUCH_DATABASE environment variableDavid Bremner
The additional code is trivial, but making sure we get the priority of various options correct takes a few tests.
2021-03-19CLI/show: complete conversion to new configuration framework.David Bremner
In order to open the database in main() for this command, we may need to re-open it in the (possibly less common) case where crypto options require write access.
2021-03-18CLI/new: drop the write lock to run the pre-new hook.David Bremner
This fixes a bug reported in [1]. In principle it could be possible avoid one of these reopens, but it complicates the logic in main with respect to creating new databases. [1]: id:9C1993DF-84BD-4199-A9C8-BADA98498812@bubblegen.co.uk
2021-03-18test: Add tests for write access to database from hooks.David Bremner
Recent changes to configuration handling meant the pre-new hook was run while the database was open read only, limiting what could be done in the hook. Add some known broken tests for this problem, as well as a regression test for write access from the post-new hook.
2021-03-18lib: support reopening databases for write access.David Bremner
In the future Xapian will apparently support this more conveniently for the cases other than READ_ONLY => READ_ONLY Conceptually this function seems to fit better in lib/open.cc; database.cc is still large enough that moving the function makes sense.
2021-03-18lib: save path of xapian database in notmuch struct.David Bremner
This will allow re-opening in a different mode (read/write vs. read-only) with current Xapian API. It will also prove useful when updating the compact functions to support more flexible database location.
2021-03-18lib: publish API for notmuch_database_reopenDavid Bremner
Include the (currently unused) mode argument which will specify which mode to re-open the database in. Functionality and docs to be finalized in a followup commit.
2021-03-18test/setup: add check for config exists, but no database.David Bremner
This code path is not currently tested, and will need updating if the location of the xapian database changes.
