histedit: move `continue` logic into a dedicated function When histedit "continue", there is several complicated logic to apply in order to detect intermediate changeset and concluded pending operation. This changeset extract this logic in a dedicated function to lighten the main one. No alteration to the logic is done.

histedit: rename `tip` to `topmost` I expected `tip` to be repo's tip when it was the rewritten set tip. I rename the variable to the less ambiguous `topmost`.

histedit: factorise node stripping logic Create a function dedicated to stripping a group of node. All existing duplicated code is replaced by call to this function. This new function take care of stripping known and relevant node only.

histedit: extract bookmark logic in a dedicated function This lighten the main function and will help to see future changes to this bookmark logic.

histedit: remove all usages of hex[:12] - `node.hex(n)[:12]` is the same as `node.short(n)` - `ctx.hex()[:12]` is the same as `str(ctx)`

largefiles: enable islfilesrepo() prior to a commit (issue3541) Previously, even if a file was added with --large, 'hg addremove' or 'hg ci -A' would add all files (including the previously added large files) as normal files. Only after a commit where a file was added with --large would subsequent adds or 'ci -A' take into account the minsize or the pattern configuration. This change more closely follows the help for largefiles, which mentions that 'add --large' is required to enable the configuration, but doesn't mention the previously required commit. Also, if 'hg add --large' was performed and then 'hg forget <file>' (both before a largefile enabling commit), the forget command would error out saying '.hglf/<file> not tracked'. This is also fixed. This reports that a repo is largefiles enabled as soon as a file is added with --large, which enables 'add', 'addremove' and 'ci -A' to honor the config settings before the first commit. Note that prior to the next commit, if all largefiles are forgotten, the repository goes back to reporting the repo as not largefiles enabled. It makes no sense to handle this by adding a --large option to 'addremove', because then it would also be needed for 'commit', but only when '-A' is specified. While this gets around the awkwardness of having to add a largefile, then commit it, and then addremove the other files when importing an existing codebase (and preserving that extra commit in permanent history), it does still require finding and manually adding one of the files as --large. Therefore it is probably desirable to have a --large option for init as well.

largefiles: handle commit -A properly, after a --large commit (issue3542) Previous to this, 'commit -A' would add as normal files, files that were already committed as largefiles, resulting in files being listed twice by 'status -A'. It also missed when (only) a largefile was deleted, even though status reported it as '!'. This also has the side effect of properly reporting the state of the affected largefiles in the post commit hook after a remove that also affected a normal file (the largefiles used to be 'R', now are properly absent). Since scmutil.addremove() is called both by the ui command (after some trivial argument validation) and during the commit process when -A is specified, it seems like a more appropriate method to wrap than the addremove command. Currently, a repo is only enabled to use largefiles after an add that explicitly identifies some file as large, and a subsequent commit. Therefore, this patch only changes behavior after such a largefile enabling commit. Note that in the test, if the final commit had a '-v', 'removing large8' would be printed twice. Both of these originate in removelargefiles(). The first print is in verbose mode after traversing remove + forget, the second is because the '_isaddremove' attr is set and 'after' is not.

i18n-ru: fix spelling of "unrecognized response" translation

localrepo: use "vfs" constructor/field for initialization around "store"

store: initialize "vfs" fields by "vfs" constructors For backwards compatibility, "opener" fields are still left as aliases for "vfs" ones.

store: rename "op" variables to "vfs"

store: rename "openertype" argument to "vfstype"

localrepo: use "vfs" constructor instead of "opener" one This patch also changes initialization order of "*opener" and "*vfs" fields: first, "*vfs" fields are initialized , and then, "*opener" ones are initialized.

scmutil: rename classes from "opener" to "vfs" For backwards compatibility, aliases for the old names are added, except for "abstractopener", "statichttpopener" and "_fncacheopener", because these are not used in Mercurial core implementation after this patch. "_fncacheopener" was only referred in "fncachestore" constructor, so this patch also renames from "_fncacheopener" to "_fncachevfs" there.

doc: add the tool to check section marks in help documents This patch adds "doc/check-seclevel.py" which checks below in help documents: - whether unknown or unavailable section marks are used or not - whether appropriate section mark is used at sub-sectioning It should be invoked in "doc" directory. It checks all help documents of Mercurial (topics, commands, extensions), if no file is specified by --file option. With --file option, it checks contents of the specified file as help document, for self testing purpose: -t/-c/-e/-C are used to specify what kind of help document contents of the specified file is. This checking is related to changeset 979b107eaea2.

histedit: replaces patching logic by merges The old and fragile patching logic is replaced by smart merges (as rebase and graft do). This should prevents some conflicts and smoother human resolution. For this purpose the "foldchanges" function is renamed to "applychanges" and handle a single revision only.

histedit-test: ensure that non commute test will never commute The previous version would commute if using merge algorithm (to be accurate, merge will cleanly prompt the user during the merge). The new version create and initial commit with some content for all involved files en ensure all changes are a content changes of the first lines. This lead to guaranteed conflict when commuted.

histedit: display action being processed in debug mode This is very useful when debugging histedit.

histedit: fold in memory Update the folding code to works in memory instead of applying patches on the working directory. This is cleaner, faster and prepare the removal of the whole patching logic. This new collapse function will probably move into core sooner or later. A lot of other rewriting operation may benefit from it.

histedit: move makedesc function near other rules related function Having it in the middle of action logic is confusing

histedit: move `between function` outside the action logic Having this function in the middle of action and patching logic did not make sense

template: add join function This allows: {join(files % "{files}", ", ") }\n to produce a properly comma-separated list

templater: factor out runtemplate method As a side-effect, this makes the output of runmap non-flattened

templating: make new-style templating features work with command line lists

formatter: improve implementation of data method This alternate syntax was proposed by Bryan O'Sullivan in a review of 772b3764d3e8. I haven't been able to measure any particular performance difference, but the new syntax is more concise and easier to read.

archival: add "extended-timestamp" extra block for zip archives (issue3600) Before this patch, zip archives created by "hg archive" are extracted with unexpected timestamp, if TZ is not configured as GMT. This patch adds "extended-timestamp" extra block to zip archives, and unzip will extract such archives with timestamp specified in added extra block, even though TZ is not configured as GMT. Please see documents below for detail about specification of zip file format and "extended-timestamp" extra block: http://www.pkware.com/documents/casestudies/APPNOTE.TXT http://www.opensource.apple.com/source/zip/zip-6/unzip/unzip/proginfo/extra.fld Original implementation of this patch was suggested by "Jun Omae <jun66j5@gmail.com>".

bookmarks: use "changectx.descendant()" for efficient descendant examination This patch uses "old.descendant(new)" expression instead of "new in old.descendants()" for efficiency.

context: add "descendant()" to changectx for efficient descendant examination This patch adds "descendant()", which uses "revlog.descendant()" for descendant examination, to changectx. This implementation is more efficient than "new in old.descendants()" expression, because: - "changectx.descendants()" creates temporary "changectx" objects, but "revlog.descendant()" doesn't "revlog.descendant()" checks only revision numbers of descendants. - "revlog.descendant()" stops scanning, when scanning of all revisions less than one of examination target is finished this can avoid useless scanning in "not descendant" case.

store: use native fncache encoding function if available This currently falls back to Python for hashed encoding.

tests: run test-hybridencode.py over both Python and C encoders This ensures that the two always give the same answers.

store: implement fncache basic path encoding in C (This is not yet enabled; it will be turned on in a followup patch.) The path encoding performed by fncache is complex and (perhaps surprisingly) slow enough to negatively affect the overall performance of Mercurial. For a short path (< 120 bytes), the Python code can be reduced to a fairly tractable state machine that either determines that nothing needs to be done in a single pass, or performs the encoding in a second pass. For longer paths, we avoid the more complicated hashed encoding scheme for now, and fall back to Python. Raw performance: I measured in a repo containing 150,000 files in its tip manifest, with a median path name length of 57 bytes, and 95th percentile of 96 bytes. In this repo, the Python code takes 3.1 seconds to encode all path names, while the hybrid C-and-Python code (called from Python) takes 0.21 seconds, for a speedup of about 14. Across several other large repositories, I've measured the speedup from the C code at between 26x and 40x. For path names above 120 bytes where we must fall back to Python for hashed encoding, the speedup is about 1.7x. Thus absolute performance will depend strongly on the characteristics of a particular repository.

rebase: ensure rebase does not revive extinct revision Here, we exclude hidden changesets from a rebase operation. If we don't, a rewritten version of the hidden changesets will be created by rebase. Those rewritten versions won't be hidden and will likely conflict with other rewriting or revive pruned changeset. Moreover, rewriting hidden revisions will surprise the user. This change would not be necessary if changelog filtering were already in core. But it's fairly cheap and helps to increase the test-suite for such filtering. Once changelog level filtering is added, hidden changes will be automatically excluded or included according to the global --hidden flags. Plain ignoring them is good enough for now.

rebase: remove useless list around repo.revs As repo.revs already returns a list.

rebase: properly handle --collapse when creating obsolescence marker In collapse mode, that content of state is not suitable to compute obsolescence markers. We explicitly pass the resulting revision instead and use it as the successors for all elements of the rebased set.

rebase: allow creation obsolescence relation instead of stripping When obsolescence feature is enabled we now create markers from the rebased set to the resulting set instead of stripping. The "state" mapping built by rebase holds all necessary data. Changesets "deleted" by the rebase are marked "succeeded" by the changeset they would be rebased one. That the best guess of "successors" we have. Getting a successors as meaningful as possible is important for automatic resolution of obsolescence troubles. In other word, emptied changeset will looks collapsed with their former parents. (see "empty changeset" section of the test if you are still confused)

rebase: extract final changesets cleanup logic in a dedicated function At the end of the rebase, rebased changesets are currently stripped. This behavior will be eventually dropped in favor of obsolescence marker creation. The main rebase function is already big and branchy enough. This changeset move the clean-up logic in a dedicated function before we make it more complex.
