2022-04-28imap: avoid crash when replying to unread messageRobin Jarry
When running `:reply -q` on an unread message, aerc crashes after opening the editor: panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x1 addr=0x18 pc=0x5d1019] goroutine 63 [running]: bufio.(*Reader).fill(0xc000086ef8) /usr/lib/golang/src/bufio/bufio.go:106 +0xd9 bufio.(*Reader).Peek(0xc00020bef8, 0x1) /usr/lib/golang/src/bufio/bufio.go:144 +0x5d github.com/emersion/go-message/textproto.ReadHeader(0xc00004a700?) emersion/go-message@v0.15.0/textproto/header.go:525 +0x5f git.sr.ht/~rjarry/aerc/worker/imap.(*IMAPWorker).handleFetchMessageBodyPart.func1(0xc00056e280) worker/imap/fetch.go:99 +0x1ab git.sr.ht/~rjarry/aerc/worker/imap.(*IMAPWorker).handleFetchMessages.func1() worker/imap/fetch.go:178 +0xd7 created by git.sr.ht/~rjarry/aerc/worker/imap.(*IMAPWorker).handleFetchMessages worker/imap/fetch.go:172 +0x12b This happens because the flags are updated in the callback that receives the message itself.

2022-04-27feat: add gpg integrationTim Culverhouse
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. If it is not explicitly set to "gpg", aerc will default to it's internal pgp provider * pgp-key-id: (Optionally) specify a key by short or long keyId Signed-off-by: Tim Culverhouse <tim@timculverhouse.com> Acked-by: Koni Marti <koni.marti@gmail.com> Acked-by: Robin Jarry <robin@jarry.cc>

2022-04-25pgp: ensure CRLF line endings in pgpmail readerKoni Marti
Ensure CRLF line endings in the pgpmail reader. Fix the pgp signature verification for maildir and notmuch. These backends do not return the full message body with CRLF line endings. But the accepted OpenPGP convention is for signed data to end with a <CR><LF> sequence (see RFC3156). If this is not the case the signed and transmitted data are considered not the same and thus signature verification fails.

2022-04-14Initialization fix for dynamic foldersAivars Vaivods
There is an issue with backends, that provide dynamic folders, namely when opening folder, that isn't defined in config file, you get empty folder. To actually get messages listed, you need to open that folder twice. At first attempt only DirectoryInfo is fetched and new MessageStore created. Second attempt populates previously created MessageStore with list of messages. For pre-configured folders, DirectoryInfos are fetched upon connection to backend and, when folder is opened, MessageStore is updated with list of messages.

2022-04-11imap: fix no-envelope-for-message errorKoni Marti
Fix the "no envelope available for this message" error that can occur when using the same imap mailbox in another mailclient (e.g. through a webmail interface) at the same time. Complements the fixes in commit 7fe7fe4 ("ui: fix panic in header formatter") and commit 074b0a1 ("view,list: fix crash when viewing incomplete imap messages"). The error is caused when a message attribute update is received by the message store before the message list had a chance to fetch the proper header first. In this case, an (incomplete) message info is stored in the message store and the message list will never fetch the correct header. To prevent this, add only messages to the store with a non-nil envelope but make sure that message attribute updates are properly merged.

The LDFLAGS environment variable is usually indented for C the linker flags which are not compatible with go -ldflags. Use a more explicit GO_LDFLAGS variable instead. Allow adding extra flags without overriding the default ones by specifying GO_EXTRA_LDFLAGS. This may break the build on some distros that rely on setting LDFLAGS to change the default shareDir or version. They will have to switch to GO_EXTRA_LDFLAGS.

Keep the sort criteria applied to the selected folder until the default sort order should be restored. Call the sort command without arguments to restore the default sort order. The current behavior is that the default sort order is restored as soon as the folder reloads. This happens often and then the results of the sort command are lost. This makes the sort command not very user-friendly. Instead, we should keep the sort criteria applied until the user explicitly wants to restore the default sort order again.
