I've been attempting to port nmweb to the new bindings, but I got stuck on a bug that segfaults python. I attached a reduced version that reproduces the problem for me. It uses recent messages from the notmuch list; it others can't reproduce let me know and I will try to make something more self contained including a message set.
It's a bit tricky to get ASAN working but I managed with % env ASAN_OPTIONS=alloc_dealloc_mismatch=0 LD_PRELOAD="libasan.so.6 libstdc++.so.6" LD_LIBRARY_PATH=../../lib python3 ~/test.py You can see in the attached output that one of the notmuch messages structs is used after being freed. I suspect it has something to do with the iterator code in the bindings, but I have not examined it in detail.
from notmuch2 import Database
def mailto_addrs(msg,header_name):
hdr = msg.header(header_name)
return
def show_msgs(msgs):
print("show msgs" + str(msgs))
for msg in msgs:
print("\t",msg.messageid)
frm = mailto_addrs(msg,'From')
rs = show_msgs(msg.replies())
return
db = Database(config=Database.CONFIG.SEARCH)
msg=db.find("87fsqijx7u....@metapensiero.it")
threads = db.threads(query="thread:"+msg.threadid)
thread = next (threads)
show_msgs(thread)
