templater: drop bool support from evalastype() Future patches will split evalastype() into two functions, evalrawexp() and unwrapastype(), so we can catch the exception of type conversion. # evaluating function may bubble up inner ParseError thing = evalrawexp(context, mapping, arg) try: return unwrapastype(context, thing) except ParseError: # add hint and reraise However, evalboolean() can't be factored out in this way since it has to process boolean-like symbols as non keyword. Fortunately, it's unlikely that we'll need a general type converter supporting bool, so this patch drops it from the table.

templater: do not use stringify() to concatenate flattened template output

templateutil: reimplement stringify() using flatten()

templateutil: move flatten() from templater It's the same kind of utility as stringify().

stringutil: move person function from templatefilters Move the person function from template filters to the stringutil module, so it can be reused in the mailmap template function. Differential Revision: https://phab.mercurial-scm.org/D2960

stringutil: add isauthorwellformed function The regular expression for this function formerly lived at https://hg.mozilla.org/hgcustom/version-control-tools/file/tip/hghooks/mozhghooks/author_format.py#l13 Differential Revision: https://phab.mercurial-scm.org/D2959

test-lfs-test-server: add a testcase for `hg serve` I haven't figured out yet how to make the authentication checks work for a specific list of users, so the 'web.allow-push' list is wildcarded. (It appears that the client doesn't react to a 401 by sending authentication data, which may be caused in part by not having all of the headers in httpbasicauthhandler's http_error_auth_reqed(), compared to a run of test-http.t. But in any case, we should probably have a separate set of tests for various authentication scenarios. As it is, without the wildcard, no push access is granted.) There are several deviations from the `lfs-test-server` case: - `hg serve` emits a Server header. I think Gregory indicated that this isn't easily suppressed. - `hg serve` names the "basic" transfer handler in the Batch API response. Not having to specify it was for backwards compatability, so this seems like the right thing to do. (`lfs-test-server` doesn't name it, whether it was explicitly requested by the client or not.) - PUT status for a newly created file is 201, per RFC-2616 [1]. The Basic Transfer API [2] shows an example upload transcript with a 200 response. It doesn't make much sense to re-upload a file (unless it is corrupt) in an example, but I wouldn't be surprised if some other implementations also expect 200 because of this. But the RFC says MUST use 201 for creation. - The Content-Type for the file transfers is "application/octet-stream", like the sample transcript (though I don't see it explicitly called out in the text elsewhere). Using "text/plain" seems clearly wrong. - `lfs-test-server` isn't removing the action property and sending back an error code like the spec calls out when a file is missing or corrupt. Doing so on the `hg serve` side reveals a bug in our client code when handling the response- it indicates the remote file is missing instead of corrupt around line 452. I'll probably glob over the Content-Length differences once this settles down. Prior to the recent hgweb refactoring, the Batch API response was using chunked encodings instead. Back to the RFC, I have no idea if the python framework handles the "MUST NOT ignore any Content-* (e.g. Content-Range) headers that it does not understand or implement and MUST return a 501" for a PUT request.
