hgweb: do not ignore [auth] if url has a username (issue2822)
The [auth] section was ignored when handling URLs like:
http://user@example.com/foo
Instead, we look in [auth] for an entry matching the URL and supplied user
name. Entries without username can match URL with a username. Prefix length
ties are resolved in favor of entries matching the username. With:
foo.prefix = http://example.org
foo.username = user
foo.password = password
bar.prefix = http://example.org/bar
and the input URL:
http://user@example.org/bar
the 'bar' entry will be selected because of prefix length, therefore prompting
for a password. This behaviour ensure that entries selection is consistent when
looking for credentials or for certificates, and that certificates can be
picked even if their entries do no define usernames while the URL does.
Additionally, entries without a username matched against a username are
returned as if they did have requested username set to avoid prompting again
for a username if the password is not set.
v2: reparse the URL in readauthforuri() to handle HTTP and HTTPS similarly.
v3: allow unset usernames to match URL usernames to pick certificates. Resolve
prefix length ties in favor of entries with usernames.
Corrupt an hg repo with a pull started during an aborted commit
Create two repos, so that one of them can pull from the other one.
$ hg init source
$ cd source
$ touch foo
$ hg add foo
$ hg ci -m 'add foo'
$ hg clone . ../corrupted
updating to branch default
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ echo >> foo
$ hg ci -m 'change foo'
Add a hook to wait 5 seconds and then abort the commit
$ cd ../corrupted
$ echo '[hooks]' >> .hg/hgrc
$ echo 'pretxncommit = sleep 5; exit 1' >> .hg/hgrc
start a commit...
$ touch bar
$ hg add bar
$ hg ci -m 'add bar' &
... and start a pull while the commit is still running
$ sleep 1
$ hg pull ../source 2>/dev/null
pulling from ../source
transaction abort!
rollback completed
