Mercurial API: reading config over https

Question

In the Mercurial API, is there any way to read the configuration values associated with a repository that you're accessing over HTTPS? The repository's ui object doesn't seem to hold them.

Answer 1

The short answer is "no". There is no way to read the config values from a repo over HTTP using the Mercurial API. These values are never transmitted over the network. A more detailed explanation follows.

---

The ui.ui() class provides access to system, user and local repository config values.

>>> from mercurial import hg, ui
>>> u = ui.ui()
>>> u.configlist('ui', 'username')
['Your', 'Name', '<your@email.com>']

The constructor for a repository object requires a ui object and a path to be provided.

The values from ui are copied into the repo object.

If path is a local repository, then the config settings for that repository may be accessed via repo.ui. However if path is a URL, the API does not query the remote server for config settings. In that case, repo.ui only includes the system and user settings.

>>> repo = hg.repository(ui.ui(), '.')
>>> repo.ui.configlist('paths', 'default')
['https://www.mercurial-scm.org/repo/hg']

... start an hg serve session at http://localhost:8000 ...

>>> repo = hg.repository(ui.ui(), 'http://localhost:8000')
>>> repo.ui.configlist('paths', 'default')
