Mercurial TextAuth plugin error “Parse exception: '*** failed to import extension textauth.file from C:\inetpub\auth: invalid syntax (auth, line 1)'”

Question

I've installed the TextAuth plugin to Mercurial to add basic authentication for pulling/pushing code.

Via Tortoise HG Mercurial interface, I get the error below, but the operation continues and authentication is accepted and working correctly, i.e, if I change the username inside the file named "auth", the old one is no longer accepted, etc.

This wasn't a problem until I started using Zend Studio with the Mercurial Eclipse plugin, the same error is thrown from Mercurial, but Zend/Eclipse doesn't continue, like the Tortoise HG workbench does, so it's stopping work completely...

Any help would be great, thanks.

"Parse exception: '*** failed to import extension textauth.file from C:\inetpub\auth: invalid syntax (auth, line 1)'"

EDIT: Here is the contents of the plain text file. It's UTF-8 without BOM.

The passwords have had characters scrambled, so if you try it and it doesn't work, that's why, but they were generated by the authedit command, and are accepted during authentication.

Here is the contents of the hgrc file with obvious stuff obfuscated/changed.

# Generated by TortoiseHg


[web]
push_ssl = False
allow_push = *
[ui]

Answer 1

I can't find reference to the textauth plugin online, but I suspect this is your problem:

[extensions]
textauth = C:\inetpub\textauth.py
textauth.file = C:\inetpub\auth

That's saying "load two separate extensions one called textauth and one (illegally) called textauth.file.

You want this:

[extensions]
textauth = C:\inetpub\textauth.py

[textauth]
file = C:\inetpub\auth

So just remove the textauth.file = line in the [extensions] section.

It's an easy mistake to make because when given on the command line the [section] and key syntax does become section.key like this:

hg --config ui.username=david ...

but in a .hgrc that's:

[ui]
username = david

Answer 2

Everything under [extensions] is treated as a plugin. The C:\inetpub\auth file is not a plugin, it's a file used by a plugin. You should just have (in addition to the textauth.py extension of course):

[textauth]
file = C:\inetpub\auth

This part of the documentation is where that is explained, it would have been nice if they had given an example:

textauth

Section that controls the behavior of the textauth extension.

Supported arguments:

file The path to the file containing authentication information. The contents of this file should be as described below.
