Sieve regex behavior
Hi,
I'm having troubles lately with a Sieve script of mine:
require "fileinto";
require "mailbox";
require "regex";
if header :regex "Subject" "\\[.*PATCH.*\\]" {
fileinto :create "Inbox.Patches";
}This should move all patches with "[PATCH]" or "[RFC PATCH v3]" into this Inbox subfolder, I'm pretty sure this version worked flawlessly in the past but since a couple of weeks ago it's not working with some emails.
Debugging this, with manually editing mail files, I came to this discovery. That one mail matches and it's getting moved to the correct folder:
Subject: Re: [PATCH v2 3/6] arm64: dts: qcom: qcm6490-shift-otter: AAdding one more character leads to it not getting moved:
Subject: Re: [PATCH v2 3/6] arm64: dts: qcom: qcm6490-shift-otter: Ad
Does anybody have an explanation for this why this broke, and how to fix either Dovecot/Pigeonhole or my Sieve script?
I've already lost hours trying to figure this out and I'm not getting any wiser...
Regards Luca
2.4.2 replaced libc regex(3) with libpcre2, maybe it is this?

You may find it helpful to test the regex at command line. e.g.
$ pcre2test PCRE2 version 10.47 2025-10-21 (8-bit) re> '\[.*PATCH.*\]' data> 'Subject: Re: [PATCH v2 3/6] arm64: dts: qcom: qcm6490-shift-otter: Ad' 0: [PATCH v2 3/6] data> 'Subject: Re: [PATCH v2 3/6] arm64: dts: qcom: qcm6490-shift-otter: A' 0: [PATCH v2 3/6] data> '[RFC PATCH v3]' 0: [RFC PATCH v3] data> '[xxx]' No match data> 'PATCH' No match
