* imap: only call UidSort with sort criteriaKoni Marti2023-06-251-2/+3
| | | | | | | | | | | | | Only call UidSort with some sort criteria. If we call it without, some imap severs report it as an error. For example, Fastmail imap with the sort config in aerc.conf commented out reports: "[Fastmail] unexpected error: Missing Sort criteria" and cannot display the messages.

* logging: remove ultra verbose trace logsRobin Jarry2023-06-123-21/+2
| | | | | | | | | | | | | | | | | Every message exchanged between the UI and the worker(s) is logged at least twice with some obscure IDs and struct pointer names. When enabling trace logging, this floods the files for very little or no benefit and makes the meaningful logging message hard to catch. Also, other messages tend to flood the output for no specific reason. These are most of the time leftovers from the development process and are not useful for tracking potential issues. Remove these.

* headers: enable partial header fetchingTim Culverhouse2023-05-164-4/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | Enable partial header fetching by creating config values for headers to specifically include, or specifically exclude. The References field will always be fetched, regardless of the include list. Envelope data is always fetched, but is not shown with :toggle-headers, since it isn't in the RFC822 struct unless explicitly included in the list. Partial headers can break the cache on changes. Update the cache tag key to include the state of the partially-fetched headers. Partial header fetching can have a significant performance increase for IMAP, and for all backends a resource improvement. Some data to support this is below. Gathered by opening aerc, selecting a mailbox with approximately 800 messages and scrolling to the end.

* imap: handle the NonExistent attributeKoni Marti2023-05-161-1/+4
| | | | | | | | | | | | | | | | | | Treat the "\NonExistent" attribute similar to the "\NoSelect" one. Only list folders without the "\NonExistent" or "\NoSelect" attribute. According to RFC 9501, section 7.3.1, the "\NonExistent" attribute implies "\NoSelect". When using the LIST-STATUS extension, some servers return a "\NonExistent" flag instead of the "\NoSelect" one. We only check for the "\NoSelect" attribute, and hence, a "\NonExistent" folder will appear in the directory list and raise an error when being selected. This occurs, e.g., for gmail accounts with the "[Gmail]" folder. Signed-off-by: Koni Marti <koni.marti@gmail.com> Acked-by: Robin Jarry <robin@jarry.cc>

* msgstore: fetch message list based on OpenDirectory msgTim Culverhouse2023-04-222-2/+0
| | | | | | | | | | | | | | | Fetching the message list is done in a convoluted way. The UI receives a DirectoryInfo message, which creates a message store. It then receives a second DirectoryInfo (an oddity from the IMAP worker), and this DirectoryInfo is passed to the message store which then requests a fetch of the message list via store.Sort. Use the OpenDirectory done response to tell the message store to fetch messages. This makes the code easier to follow, and does not rely on quirks from the IMAP worker.

* imap,smtp: cache and cycle XOAUTH2 refresh tokenDean2023-01-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Normally for emails with xoauth2, the help page says to pass the refresh token as the password. When the refresh token expires, aerc can't fetch the access token, and you must get a new refresh token from the external script. This patch implements a cycle of refresh tokens so you only need to use an external script to fetch the refresh token once. Once you have fetched the initial refresh token (with an external script like mutt_xoauth2.py or https://github.com/gaoDean/oauthRefreshToken), that refresh token is inputted as the password to aerc (as normal) to fetch the access token. Before this patch aerc used to only fetch the access token, but now it fetches that and a new refresh token, which it caches in $XDG_CONFIG_HOME/aerc/<account>-xoauth2.token. In the next opening of aerc, aerc will pull the refresh token from the cache, and use it instead of the inputted refresh token from the password. If it is not present in the cache, the refresh token is taken from the password as usual. Signed-off-by: Dean <gao.dean@hotmail.com> Acked-by: Robin Jarry <robin@jarry.cc>

| | | | | | | | | | | | | | | | | | | | | Add XOAUTH2 authentication support for IMAP and SMTP. Although XOAUTH2 is now deprecated in favor of OAuthBearer, it is the only way to connect to Office365 since Basic Auth is now completely removed. Since XOAUTH2 is very similar to OAuthBearer and uses the same configuration parameters, this is basically a copy-paste of the existing OAuthBearer code. However, XOAUTH2 support was removed from go-sasl library, so this change reimports the code that was removed from go-sasl and offers it a new home in lib/xoauth2.go. Hopefully it shouldn't be too hard to maintain, being less than 50 SLOC.
