hgweb: use template context to render {files} of changelist entries This is a preferred way to process nested templates.

hgweb: wrap {files} of changelist entries with mappedgenerator This also switches the associated templates conditionally, which can't be a mappinggenerator.

hgweb: use template context to render {files} of changesetentry() This is a preferred way to process nested templates.

hgweb: wrap {files} of changesetentry() with mappedgenerator This can't be easily adapted to mappinggenerator because the associated templates are switched per item.

hgweb: extract generator of {files} from changesetentry() This will be wrapped with mappedgenerator.

templatefilters: document the json filter I don't know the exact reason why it was undocumented, but that would be because unicode is difficult for humans. Since the json filter can now get localstr back to UTF-8 as long as it is unprocessed (i.e. {desc|json} works, but {desc|firstline|json} doesn't), it seems good enough to advertise the json filter.

encoding: introduce tagging type for non-lossy non-ASCII string This fixes the weird behavior of toutf8b(), which would convert a local string back to UTF-8 *only if* it was lossy in the system encoding. Before b7b26e54e37a "encoding: avoid localstr when a string can be encoded losslessly (issue2763)", all local strings were wrapped by the localstr class. I think this would justify the round-trip behavior of toutf8b(). ASCII strings are special-cased, so the cost of wrapping with safelocalstr is negligible.

encoding: fix toutf8b() to resurrect lossy characters even if "\xed" in it If 's' is a localstr, 's._utf8' must be returned to get the original UTF-8 sequence back. Because of this, it was totally wrong to test if '"\xed" not in s', which should be either '"\xed" not in s._utf8' or just omitted. This patch moves the localstr handling to top as the validity of 's._utf8' should be pre-checked by encoding.tolocal().

sshserver: redirect stdin/stdout early and use duplicated streams This is what we achieved with hook.redirect(True) plus ui.fout = ui.ferr. The hook.redirect() function can't be completely removed yet since hgweb still depends on it. I'm not sure if it is necessary for WSGI servers. CGI needs it, but does WSGI communicate over stdin/stdout channels?

sshserver: do setbinary() by caller (API) In most cases, stdio should be set to binary mode by the dispatcher, so the sshserver does not have to take care of that. The only exception was hg-ssh, which is fixed by this patch. .. api:: ``sshserver()`` no longer sets stdin and stdout to binary mode.
