copies: add more details to the documentation of mergecopies() This documentation is very helpful for any developer to understand what copytracing is and what the function does. Since this is the main function of doing copytracing, I have also included bits about copytracing in it. This additions are picked from a doc by Stash@Fb. So thanks to him.

httppeer: add support for httppostargs when we're sending a file This is probably only used in the 'unbundle' command, but the code ended up being cleaner to make it generic and treat *all* httppostargs with a non-args request body as though they were file-like in nature. It also means we get test coverage more or less for free. A previous version of this change didn't use io.BytesIO, and it was a lot more complicated. This also fixes a server-side bug, so anyone using httppostargs should update all of their servers to this revision or later *before* this gets to their clients, otherwise servers will hang trying to over-read the POST body.

i18n: get translation entries for description of each compression engines Now, hggettext can be applied safely on util.py, of which i18nfunctions contains appropriate objects related to each compression types.

i18n: ignore docstring for modules under mercurial Docstring of modules is needed only for "hg help -e EXTNAME". This is a preparation for applying hggettext on util.py, which has module docstring, but it isn't needed for translation.

i18n: use saved object to get actual function information if available To list up available compression types instead of ".. bundlecompressionmarker" in "hg help bundlespec" output, proxy object "docobject" is used, because: - current online help system requires that __doc__ of registered object (maybe, function) is already well formatted in reST syntax - bundletype() method of compressionengine classes is used to list up available compression types, but - __doc__ of bundletype() object (= "instancemethod") is read-only On the other hand, hggettext requires original function object, in order to get document location in source code. Therefore, description of each compression types isn't yet translatable. Even if translatable, translators should make much effort to determine location of original texts in source code. To get actual function information, this patch makes hggettext use function object saved as "_origfunc", if it is available. This patch also changes bundlecompressiontopics() side, in order to explain how these changes work easily. This patch is a part of preparations for making description of each compression types translatable.

i18n: ignore doctest part to avoid warning at "make update-pot" hggettext assumes that backslashes in docstring are always doubled in original source code, in order to find the location of original docstring out certainly. This assumption almost always works as expected. But doctest easily breaks it, because many of backslashes in doctests aren't doubled. This mismatching causes "unknown offset in ..." warning at "make update-pot". To avoid such warning, this patch ignores doctest part of docstring before finding the location of original docstring out. BTW, at this patch, only person() in templatefilters.py has doctest part, which causes "unknown offset ..." warning. Therefore, just making backslashes in that doctest doubled can avoid such warning, too. But forcing doctest writers to double backslashes in doctest isn't reasonable, IMHO.

largefiles: fix help text to avoid warning at "make update-pot" This change helps hggettext to find out help text in original source, because it assumes that backslash ('\') is doubled in docstring.

i18n: make hggettext use original docstring to compute offset Before this patch, hggettext uses __doc__ of each functions to compute offset of document text. But __doc__ of many functions is already modified by decorators in registrar (e.g. @templatekeyword adds ":NAME: " prefix to it), and hggettext can not find it out in original source. This causes many "unknown offset in ..." warning at "make update-pot", and leaving them might cause overlooking serious problems. This patch makes hggettext use original docstring, which decorators in registrar save into _origdoc, to compute offset. Even after this patch, there are still a few "unknown offset in ..." warning at "make update-pot" for specific reasons. These will be fixed later one by one.

run-tests: also color the summary messages (skipped, failed...)

crecord: fixes the formatting of the select status in the status line The status line in the crecord has the "space" status field which has variable length depending on the length of the status label in the language of choice. In English, the status labels are "space: deselect" and "space:select". The "deselect" label is 2 glyphs longer. This makes the terminal output jump around if the terminal width is just right so that the shorter label makes the status line 1 line long, and the longer label makes it 2 lines long. This patch formats the selected status into a fixed-width field. The field width is the maximum of the lengths of the two possible labels, to account for differing translations and label lengths. This should make the label behavior uniform across localizations. There does not seem to be a test for crecord, so I verified the change manually with a local build of 'hg'.
