copies: extract method for getting non-wdir forward copies I may add an alternative way of getting copy metadata (from changelog, not filelog) but the chaining with the dirstate copy metadata will be the same, so it will probably help to have this extracted. Even if that doesn't happen, the next patch will show that we can simplify this a bit after this refactoring, so it seems worth it regardless.

copies: consistently use """ for docstrings Differential Revision: https://phab.mercurial-scm.org/D1696

copies: always respect matcher arg to _forwardcopies() The function would ignore the matcher if the dirstate copies were requested. It doesn't matter in practice because all callers used the returned map only for looking up specific files from and those files had already been filtered by the matcher (AFACT). Still, it's a little confusing, so let's make it clearer by respecting the matcher in this case too. Differential Revision: https://phab.mercurial-scm.org/D1695

tests: avoid echo with backslash escapes Some shells' echo (e.g. Bash's) do not interpret backslash escapes by default, while others shells' do (e.g. Dash's). This led to a failure in test-run-tests.t. We could switch to the more compatible printf, but using a heredoc seems simpler, so that's what this patch does. For anyone who wants to test this for themselves, remove the "unset HGTEST_SHELL" line in helper-runtests.sh and pass e.g. "--shell=/bin/dash" to the test runner.

hgweb: stop using HTML comments in <script> Once upon a time, in 1995, there were browsers that didn't understand <script> tags and they would simply show the code inside as text. This started a tradition of wrapping everything inside <script> in <!-- HTML comments -->. Nowadays, it's not only not needed, but can be considered harmful[1]: - within XHTML documents, the source will actually be hidden from all browsers and rendered useless - `--` is not allowed within HTML comments, so any decrement operations in script are invalid [1]: http://www.javascripttoolbox.com/bestpractices/#comments

extdata: abort if external command exits with non-zero status (BC) Per the last discussion, this is more reliable and consistent way than suppressing an error. For grep, erroring out might be inconvenient, but for curl, non-zero exit status should be detected. The latter wouldn't be possible if non-zero status is ignored. https://www.mercurial-scm.org/pipermail/mercurial-devel/2017-October/105727.html

hgweb: update graph function docstring

rebase: fix for hgsubversion 5c25fe7fb1e broke something in the hgsubversion test path, causing it raise an abort (Abort: nothing to merge) during a perfectly good rebase. I tracked it down to this change. It's probably not hgsubversion related. I suspect that using the same `wctx` from before the initial update causes problems with the wctx's cached manifest property. I noticed we also sometimes stick random gunk on the wctx object in other places (like in `copies.py`) so it's probably best to reset it for now. The line I added before was actually useless since we don't pass wctx to the initial `merge.update`, so it defaults to `repo[None]`. So I just removed it.

hgweb: render next pages on /graph incrementally Previously, when user scrolled down to see the next page on /graph, all hgweb did was re-render everything that would be visible (by simply incrementing revcount). It was not efficient at all, and this patch makes /graph page behave similarly to the regular /log: every new page only consists of new changesets, no duplication, and only jsdata is based on the full set of changesets required to build accurate graph. This is achieved by adding "?graphtop=<node>" to the next page URL template, effectively remembering where the graph started, and using that value to create the new `tree` that covers the whole visible graph. That variable is then used to produce jsdata for redrawing graph client-side. nextentry is used for the same purpose as on /log page (to format the next page URL), but it's not a part of the graph.

hgweb: split graphdata() into jsdata() and nodes() nodes keyword passed to the template can be any iterator, but jsdata needs to be a list because it gets JSONified.

hgweb: calculate <canvas> width and height client-side hgweb determines and passes to templates some variables related to graph appearance, like bg_height, canvaswidth and canvasheight. bg_height was and still is used for graph.scale() call in graph.tmpl, and the two latter variables were used in <canvas> element as width and height properties, and they were set before JS code got to run. Setting these properties server-side doesn't make a lot of sense, because a graph that has been scaled should calculate things like width and height on its own when being rendered. Let's move (re)sizing <canvas> to JavaScript (to Graph.render function) and stop parsing HTML with regular expressions just to know new width and height. That extra loop that only counts cols is required because <canvas> can't be resized after or in the process of rendering (or it gets cleared). Incidentally, SVG doesn't have this problem and I'm hoping to switch graph to using it in future. There also was truecanvasheight, but according to hg grep --all it was never used, see d490edc71146.

hgweb: filter graphmod.colored() output before iterating over it Consumers in this function use output of graphmod.colored(), but only want items with type == CHANGESET, so let's filter it early. This is primarily just a refactoring, but it also fixes a potential small bug with `rows = len(tree)` (this variable is used for "Rows shown" line in raw-graph) if there are items of other types.

py3: introduce pycompat.ziplist as zip is a generator on Python 3 Similar to map, the return value of zip was also turned into a generator on Python 3.

memfilectx: make changectx argument mandatory in constructor (API) committablefilectx has three subclasses: workingfilectx, memfilectx, and overlayfilectx. committablefilectx takes an optional (change) ctx instance to its constructor. If it's provided, it's set on the instance as self._changectx. If not, that property is supposed to be defined by the class. However, only workingfilectx does that. The other two will have the property undefined if it's not passed in the constructor. That seems bad to me. This patch makes the changectx argument to the memfilectx constructor mandatory because that fixes the failure I ran into. It seems like we should also fix the overlayfilectx case.
