merge: standardize error message for dirty working dir

update: standardize error message for dirty update --check This and following patches will standardize the error message for dirty working directories to "uncommitted changes".

update: improve error message for dirty non-linear update with rev

update: add error message for dirty non-linear update with no rev Previously, the error message for a dirty non-linear update was the same (and relatively unhelpful) whether or not a rev was specified. This patch and an upcoming one will introduce separate, more helpful hints.

update: improve error message for clean non-linear update

pull: for pull --update with failed update, print hint if any An upcoming patch will add a hint to the abort message, and we don't want to lose that here.

debugshell: appease pyflakes

check-code: new rule to forbid imports of a.b on the same line as other imports This style of import can trip up 2to3 and cause it to produce invalid files if one of the imports is supposed to be a relative import. This prevents that behavior, and in the process exposed a lot of silly import errors related to the email module.

paper: add infinite scrolling to graph by calling ajaxScrollInit at the page

hgweb: add graph mode of ajax response processing While the default mode appends all the new entries to a container on the page, the graph mode resizes canvas correctly, and repaints the graph to include newly received data.

hgweb: make infinite scroll handling more generic and extensible Namely, this allows the next page pointer to be not only revision hash given in page code, but also any value computed from the value for previous page.

hgweb: add reset javascript function to Graph It makes the Graph object to be in the same state as just after the initialization. This will help to add infinite scrolling to graph view.

largefiles: setup "largefiles" feature in each repositories individually Before this patch, if largefiles extension is enabled once in any of target repositories, commands handling multiple repositories at a time like below misunderstand that "largefiles" feature is supported also in all other local repositories: - clone/pull from or push to localhost - recursive execution in subrepo tree This patch registers "featuresetup()" into "featuresetupfuncs" of "localrepository" to support "largefiles" features only in repositories enabling largefiles extension, instead of adding "largefiles" feature to class variable "_basesupported" of "localrepository". This patch also adds checking below to the largefiles specific class derived from "localrepository": - push to localhost: whether features supported in the local(= dst) repository satisfies ones required in the remote(= src) This can prevent useless looking up in the remote repository, when supported and required features are mismatched: "push()" of "localrepository" also checks it, but it is executed after looking up in the remote.

localrepo: make supported features manageable in each repositories individually Before this patch, all localrepositories support same features, because supported features are managed by the class variable "supported" of "localrepository". For example, "largefiles" feature provided by largefiles extension is recognized as supported, by adding the feature name to "supported" of "localrepository". So, commands handling multiple repositories at a time like below misunderstand that such features are supported also in repositories not enabling corresponded extensions: - clone/pull from or push to localhost - recursive execution in subrepo tree "reposetup()" can't be used to fix this problem, because it is invoked after checking whether supported features satisfy ones required in the target repository. So, this patch adds the set object named as "featuresetupfuncs" to "localrepository" to manage hook functions to setup supported features of each repositories. If any functions are added to "featuresetupfuncs", they are invoked, and information about supported features is managed in each repositories individually. This patch also adds checking below: - pull from localhost: whether features supported in the local(= dst) repository satisfies ones required in the remote(= src) - push to localhost: whether features supported in the remote(= dst) repository satisfies ones required in the local(= src) Managing supported features by the class variable means that there is no difference of supported features between each instances of "localrepository" in the same Python process, so such checking is not needed before this patch. Even with this patch, if intermediate bundlefile is used as pulling source, pulling indirectly from the remote repository, which requires features more than ones supported in the local, can't be prevented, because bundlefile has no information about "required features" in it.

extensions: list up only enabled extensions, if "ui" is specified Before this patch, "extensions.extensions()" always lists up all loaded extensions. So, commands handling multiple repositories at a time like below enable extensions unexpectedly. - clone from or push to localhost: extensions enabled only in the source are enabled also in the destination - pull from localhost: extensions enabled only in the destination are enabled also in the source - recursive execution in subrepo tree: extensions enabled only in the parent or some of siblings in the tree are enabled also in others In addition to it, extensions disabled locally may be enabled unexpectedly. This patch checks whether each of extensions should be listed up or not, if "ui" is specified to "extensions.extensions()", and invokes "reposetup()" of each extensions only for repositories enabling it.

largefiles: remove bailifchanged check from overridepull (BC) This brings pull --rebase with largefiles in line with pull --rebase without.

rebase: remove bailifchanged check from pullrebase (BC) This saves us a relatively superfluous status check for pull --rebase (if rebase runs, it'll check for a clean working directory anyway), and brings hg pull --rebase closer to hg pull && hg rebase. This is a behavior change because pull --rebase with a dirty working directory will now abort after performing the pull rather than before.

debugshell: check ui.debugger for which debugger to use

debugshell: add function to embed ipython

debugshell: abstract out pdb code.interact

templater: support using templates with non-standard names from map file Allow to add arbitrarily-named entries to a template map file and then reference them, to make it possible to deduplicate and simplify templates code.

help: use full name of extensions to look up them for keyword search Before this patch, "hg help -k KEYWORD" fails, if there is the extension of which name includes ".", because "extensions.load()" invoked from "help.topicmatch()" fails to look such extension up, even though it is already loaded in. "help.topicmatch()" invokes "extensions.load()" with the name gotten from "extensions.enabled()". The former expects full name of extension (= key in '[extensions]' section), but the latter returns names shortened by "split('.')[-1]". This difference causes failure of looking extension up. This patch adds "shortname" argument to "extensions.enabled()" to make it return shortened names only if it is True. "help.topicmatch()" turns it off to get full name of extensions. Then, this patch shortens full name of extensions by "split('.')[-1]" for showing them in the list of extensions. Shortening is also applied on names gotten from "extensions.disabled()" but harmless, because it returns only extensions directly under "hgext" and their names should not include ".".

hgweb: add link to force literal keyword search This makes it possible to make keyword search in case the search query also specifies an exact revision (like '1234' or 'abcdef'), or a revset expression.

raw: show current search mode name at search results

paper: show current search mode name at search results

hgweb: pass variable with current search mode name to the search template

generaldelta: initialize basecache properly Previously basecache was incorrectly initialized before adding the first revision from a changegroup. Basecache value influences when full revisions are stored in revlog (when using generaldelta). As a result it was possible to generate a generaldelta-revlog that could be bigger by arbitrary factor than its non-generaldelta equivalent.

paper: call ajaxScrollInit in shortlog This just calls ajaxScrollInit at the shortlog page template with all needed agruments. So, infinite scrolling is working now there.

hgweb: add ajaxScrollInit function, which does the ajax requests and processing This function should be correctly called on a page, otherwise there is no effect. When called, it makes ajax requests for the next portion of changesets when the user scrolls to the end. Also, when the monitor is high so that the default amount of changesets isn't enough to fill it, multiple portions are loaded if needed after the page load.

check-code: add bracket style check

util.h: getbe32() and putbe32() use intrinsic function to improve performance Refer to https://bugzilla.mozilla.org/show_bug.cgi?id=351557. It can improve byte-swapping performance by intrinsic function.
