* threading: add force-client-threads optionTim Culverhouse2022-07-102-0/+6
| | | | | | | | | | | | | | | | | | | | This patch adds a config option to force the use of client side threads. This option will override a servers Thread capability, and only build threads on the client. It can be enabled contextually. For example: [ui] threading-enabled = true [ui:folder~^Archive] force-client-threads = true This config would enable threads for all views, and use client threads for folders that start with Archive. This can be advantageous if, for example, the folder is very large and the server has a slow response due to building threads for the entire mailbox Signed-off-by: Tim Culverhouse <tim@timculverhouse.com> Acked-by: Robin Jarry <robin@jarry.cc>
* threading: enable toggle-threads for server-side threadsTim Culverhouse2022-07-101-4/+2
| | | | | | | | | | Enable the :toggle-threads command to work for workers which have Thread capability. The implementation of that feature has the side effect that the threading-enabled config option now sets the default view (threaded or not threaded) for any worker, not just IMAP or notmuch.

* perf: reduce calls to GetUiConfigTim Culverhouse2022-07-031-0/+4
| | | | | | | | | | | | | | | | | | GetUiConfig was being called many times, and came up as a high CPU user in a cpuprofile. Every call would merge a UIConfig, which is a costly operation. Ideally, we would only need to have a config for every account X every directory. We also have a context for subjects. This patch stores all FOLDER and ACCOUNT level configs and reuses those merged objects. The SUBJECT contexts are not stored in favor of merging on-the-go, with a TODO comment to deprecate that feature and implement a better per-message styling option. I suspect this feature is not used very much. Before applying this patch with my setup, GetUiConfig is called 1159 times just to open aerc. After applying, this is reduced to 37.

* config: fix setting of zero-value time.Duration config valuesTim Culverhouse2022-06-221-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using section.MapTo(struct) (go-ini), if the struct has a default value for a time.Duration type, a zero-value in the config will not overwrite the default. If the type is *time.Duration, it will be overwritten properly. One consideration was to change all time.Duration types to *time.Duration. This method was chosen for ease of implementation. For example, if you set dirlist-delay = 0s, the delay will be 200ms. This can be observed by logging the value just after mapping the ui section in config.go. A config value of 0.1ms will have a delay of 0.1ms. Currently, aerc has 4 time.Duration config values: 1. DirlistDelay - default 200 ms 2. CompletionDelay - default 250 ms 3. CheckMail - default unset (0) 4. CheckMailTimeout - default 10 s 1, 2, and 4 have a non-zero default value and are subject to this bug. Only 1 and 2 are fixed in this patch. Number 4 would not make sense to have a 0 second timeout, therefore we can prevent the user from doing this by keeping it as it is. Another option could be to set these to 0 in config.go. The default config (aerc.conf) has these keys in it with their default values. Presumably, we don't need to set them again in config.go. If a user deletes the config values out of aerc.conf, the UI will function but with 0s delays. Signed-off-by: Tim Culverhouse <tim@timculverhouse.com> Tested-by: Moritz Poldrack <moritz@poldrack.dev>
* binds: Open msgs in default Postpone folder in edit-modeTim Culverhouse2022-06-221-0/+3
| | | | | | | | | | | | | Add a default keybind to open messages in the default Postpone folder ("Drafts") in edit-mode. A frequent question on IRC is "how do I edit a draft?". When a user selects a Draft and presses <Enter>, the intent is usually to edit that draft. This commit makes this the default behaviour for the default Postpone folder.

* msgviewer: parse and display authentication resultsKoni Marti2022-06-091-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Parse the Authentication-Results header and display it in the message viewer (not enabled by default). DKIM, SPF and DMARC authentication methods are supported. Implement recommendation from RFC 7601 Sec 7.1 to have an explicit list of trustworthy hostnames before displaying the authentication results. Be aware that the authentication headers can be forged. To display the results for a specific authentication method, add the corresponding name to the layout of headers in the viewer section of aerc.conf, e.g. to display all three, use: header-layout = From|To,Cc|Bcc,Date,Subject,DKIM|SPF|DMARC More information will be displayed when "+" is appended to the authentication method name, e.g. DKIM+ or SPF+ or DMARC+. Also, add the trustworthy hosts per account with the trusted-authres parameter, e.g. trusted-authres = * to trust every host or use regular expressions for a finer control. Multiple hosts can be entered as a comma-separated list. Authentication results will only be displayed when the host is listed in the trusted-authres list.

| | | | | | | | | | | | | | | | | | | This commit adds gpg system integration. This is done through two new packages: gpgbin, which handles the system calls and parsing; and gpg which is mostly a copy of emersion/go-pgpmail with modifications to interface with package gpgbin. gpg includes tests for many cases, and by it's nature also tests package gpgbin. I separated these in case an external dependency is ever used for the gpg sys-calls/parsing (IE we mirror how go-pgpmail+openpgp currently are dependencies) Two new config options are introduced: * pgp-provider.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using aerc for multiple accounts often bindings might differ slightly between accounts. For example: * Account A archives to one directory (:archive) * Account B archives to monthly directories (:archive month) Add account specific bindings to allow the user to add a "context" to a binding group using a context specifier and a regular expression. Currently the only context specifier is 'account'. The regular expression is validated against the accounts loaded from accounts.conf and the configuration fails to load if there are no matches. Contextual bindings are merged with global bindings, with contextual bindings taking precedence, when that context is active. Bindings are be configured using a generic pattern of 'view:context=regexp'. E.g.: # Globally Applicable Archiving [messages] A = :read<Enter>:archive<Enter> # Monthly Archiving for 'Mailbox' Account [messages:account=Mailbox$] A = :read<Enter>:archive month<Enter> In the above example all accounts matching the regular expression will archive in the monthly format - all others will use the global binding.

* notmuch: allow sort by file orderKalyan Sriram2021-11-131-22/+27
| | | | | | | | | | | | When using the notmuch backend, it often makes more sense to sort folders (actual virtual folders, or queries) by the order specified in the query-map file, rather than alphabetically. This patch introduces a configuration option (disabled by default) that allows this. Additionally, due to the notmuch backend previously using maps (which are order-undefined) to store the list of queries, default query selection on aerc startup fluctuated. This patch fixes that by using slices to store query order.
