Hi > send-email: fix bug resulting in increased message number if a message is edited I don’t understand what the bug is from the title. “Message number” sounds harmless. It breaks the threading? The summary/subject could say that instead. Fix threading bug.

It feels like this part about increasing by one and if-editing gets repeated at least two times in this paragraph. > The cause of this bug was that when a person attempts to edit the > message, the whole sub process_file gets terminated, and the user is > asked to edit the message. Here’s the repetition. Also I am not familiar with the code. Just testing it I get this `6` here: Message-ID: <20250525181003.40129-6-kristofferhaugsbakk@xxxxxxxxxxxx> Which was incremented every time I did an edit with: send-email --suppress-cc=all --to=<me> \ --confirm=always one two But that turned out to be benign in my simple case since the next email used the correct In-Reply-To. So at this point (reading the paragraph) I don’t know what the bug is. > After necessary edits are done, the whole sub process_file is executed again. > The way sub process_file is designed, every time is runs, it increases the > $message_num variable by 1.

This feels like repetition again. You say that a variable is incremented because the message is edited. > This breaks the shallow thread logic which relies on $message_num > being 1 for the first message, and it gets changed in case the user > edits the first message. If I’m right in my assumption that this number is the `4` here: Message-ID: <20250525182426.41076-4-kristofferhaugsbakk@xxxxxxxxxxxx> This was the first proposed email I got with “shallow thread” (all in reply to first): git send-email --suppress-cc=all --to=<me> \ --thread --no-chain-reply-to --confirm=always one two three Then I edit all the messages. They still all manage to refer to the first message id in the thread. I still don’t understand what the bug is. ❦ $ git diagnose Collecting diagnostic info git version 2.49.0.780.g892193c3f50 cpu: x86_64 built from commit: 892193c3f509fb8a9e4e7a5a19a2e24137befda8 sizeof-long: 8 sizeof-size_t: 8 shell-path: /bin/sh libcurl: 7.81.0 OpenSSL: OpenSSL 3.0.2 15 Mar 2022 zlib: 1.2.11 SHA-1: SHA1_DC SHA-256: SHA256_BLK Repository root: /home/kristoffer/programming/git Available space on '/home/kristoffer/programming/git': 200.56 GiB (mount flags 0x1000)
