docker: install less as a build-time dependency in deb-based distros It's needed since 387a76cac28e, otherwise dpkg-checkbuilddeps errors out.

py3: add utility to forward __str__() to __bytes__() It calls unifromlocal() instead of sysstr() because __bytes__() may contain locale-dependent values such as paths.

share: use dict literal instead of dict(key=value) check-code.py has the rule, but it isn't smart enough to catch this.

py3: use r'' to prevent conversion to bytes by transformer

py3: define __bytes__ for basefilectx class The implementation is shamely copied from the __str__ function

py3: check for bytes instead of str in isinstance

py3: convert kwargs' keys' to str using pycompat.strkwargs() On Python 3, we must have keys of keyword arguments as str.

py3: convert kwargs keys' back to bytes using pycompat.byteskwargs()

py3: use "%d" % val for int rather than pycompat.bytestr Earlier I used pycompat.bytestr() to convert integers to bytes, but we can do b"%d" % val to convert that int to bytes. b'' is already added by the transformer. Thanks to Yuya for suggesting this.

extensions: call afterloaded() with loaded=False for disabled extensions If an extension was loaded but disabled due to a minimumhgversion check it will be present in the _extensions map, but set to None. The rest of the extensions code treats the extension as if it were not present in this case, but the afterloaded() function called the callback with loaded=True.

fetch: remove shorthand of --edit colliding against -e/-ssh in remoteopts (BC) Before this patch, -e/--edit and -e/--ssh of fetch command collide against each other. This causes that -e is treated as shorthand of --edit but doesn't work as same as --edit. Therefore, -e works as neither --edit nor --ssh, in practice. This issue was introduced at 595a69a01129 (or 1.0), which renamed -f/--force-editor to -e/--edit. At that point, -e was already used as shorthand of --ssh. After this patch, -e is treated as shorthand of --ssh. This patch is marked as "(BC)", because -e as shorthand of --edit in existing scripts causes failure (or unexpected result) after this patch. This impact should be less enough, because --edit mainly focuses on interactive use. BTW, test-duplicateoptions.py (since 7d171c05a631 or 1.9) can't detect this kind of issues as expected, because direct invocation of extensions.loadall() doesn't involve registration of commands defined in extensions (this issue is fixed in subsequent patch).

releasenotes: improve parsing around bullet points Earlier, on parsing the bullet points from existing release notes the bullet points after the first one weren't written correctly to the notes file. This patch makes changes to parsereleasenotesfromfile() function that introduces a new bullet_points data structure that tracks the bullets and associated subparagraph. It also makes necessary changes to the tests related to merging of bullets.

bookmarks: factor method _printer out of for loop in printbookmarks This allows even further customization via extensions for printing bookmarks. For example, in hg-git this would allow printing remote refs by just modifying the 'bmarks' parameter instead of reimplementing the old commands.bookmarks method. Furthermore, there is another benefit: now multiple extensions can chain their custom data to bookmark printing. Previously, an extension could have conflicting bookmark output due to which loaded first and overrode commands.bookmarks. Now they can all play nicely together.

bookmarks: factor out bookmark printing from commands

commands: move activebookmarklabel to bookmarks module This is going to be used in an upcoming patch that moves more methods to bookmarks.py.

commands: replace locking code with a context manager Note that this means that we're unnecessarily creating a transaction in the pure "--inactive" (i.e. when deactivating the current bookmark), but that should be harmless.

bookmarks: factor out adding a list of bookmarks logic from commands We keep the lock in the caller so that future devs are aware of the locking implications.

bookmarks: factor out rename logic from commands We keep the lock in the caller so that future devs are aware of the locking implications.

bookmarks: factor out delete logic from commands We keep the lock in the caller so that future devs are aware of the locking implications.

revset: add startdepth limit to ancestors() as internal option This is necessary to implement the set{gen} (set subscript) operator. For example, set{-n} will be translated to ancestors(set, depth=n, startdepth=n). https://www.mercurial-scm.org/wiki/RevsetOperatorPlan#ideas_from_mpm The UI is undecided and I doubt if the startdepth option would be actually useful, so the option is hidden for now. 'depth' could be extended to take min:max range, in which case, integer depth should select a single generation. ancestors(set, depth=:y) # scan up to y-th generation ancestors(set, depth=x:) # skip until (x-1)-th generation ancestors(set, depth=x) # select only x-th generation Any ideas are welcomed. # reverse(ancestors(tip)) using hg repo 3) 0.075951 4) 0.076175

revset: add depth limit to ancestors() This is proposed by the issue5374, and will be a building block of set{gen} (set subscript) operator. https://www.mercurial-scm.org/wiki/RevsetOperatorPlan#ideas_from_mpm # reverse(ancestors(tip)) using hg repo 2) 0.075408 3) 0.075951

dagop: compute depth in revancestors() generator Surprisingly, this makes revset benchmark slightly faster. I don't know why, but it appears that wrapping -inputrev by tuple is the key. So I decided to just enable depth computation by default. # reverse(ancestors(tip)) using hg repo 1) 0.081051 2) 0.075408

dagop: just compare with the last value to deduplicate input of revancestors() Since we're using a max heap, the current rev should be a duplicate only if it equals to the previous one. We don't have to maintain the whole seen set. # reverse(ancestors(tip)) using hg repo 0) 0.086420 1) 0.081051

dagop: bulk rename variables in revancestors() generator - h -> pendingheap: "h" seems too short for variable of long lifetime - current -> currev: future patches will add current "depth" variable - parent -> prev or pctx: short lifetime, follows common naming rules

dagop: comment why revancestors() doesn't heapify input revs at once I wondered why we're doing this complicated stuff without noticing the input revs may be iterated lazily in descending order. c1f666e27345 showed why.

dagop: unnest inner generator of revancestors() This just moves iterate() to module-level function.

hgweb: plug followlines action in annotate view Add the followlines.js script and corresponding parameters as data attribute on <tbody class="sourcelines"> element. Extend CSS rules so that they also match the DOM structure of annotate view. As previously, only address paper and gitweb styles (other styles do not have followlines at all).

hgweb: parameterize the tag name of elements holding followlines selection While plugging followlines.js into "annotate" view, we'll need to walk a different DOM structure from that of "filerevision" view. In particular, the selectable source line element is a <tr> in annotate view (in contrast with a <span> in filerevision view). So make this tag name a parameter of followlines.js script by passing its value as a "selectabletag" data attribute of <pre class="sourcelines"> element. As <pre class="sourcelines"> tags are getting quite long in templates, rewrite them on several lines.

gitweb: wrap table rows of annotate view into a <tbody> element We will use this element to hook data attribute for the followlines.js script to be plugged in annotate view. Also this gets symmetrical with paper style which already has a <tbody> element.
