transplant: don't honor whitespace and format-changing diffopts transplant uses diff purely internally.

hgk: don't honor whitespace and format-changing diffopts The diff-tree command is a plumbing command in Git, which means it is expected to have a stable output format. Ensure that our output is stable too.

patchbomb: don't honor whitespace and format-changing diffopts (BC) The whitespace diffopts break lossless transmission, and the format-changing ones make import harder. We expect parsers to be able to read git-style diffs, though.

merge: add more thorough tests for --force With generate-working-copy-states.py generalized to support arbitrarily many changesets, we can use it for generating test cases for merge: use one changeset each for base, remote and local. With the various working copy states, this is a total of 104 cases. The first candidate for additional testing is 'hg merge --force'. Even though the force option is deprecated, it is convenient for testing because it can be tested without first needing to revert any changes. Except for the lack of checking for uncommitted changes, it differs in only a few cases from unforced merge. The new tests cover all the cases in the existing test-merge-force.t, except for the unforced merge case, which is covered in several other files anyway, so nothing remains of the file after this patch.

merge: display modify/delete conflict prompts in sorted order The order is determined by manifest.diff(), which currently is not sorted. There are currently no tests for this, but we will soon add some that would be flaky without this patch.

generate-working-copy-states: accept depth arguments on command line Add a parameter to generate-working-copy-states.py that indicates how many changesets are wanted. This number impacts all the subcommands. The current 'filelist' subcommand becomes 'filelist 2', the current 'base' and 'parent' subcommands become 'state 2 1' and 'state 2 2' respectively, while 'wc' becomes 'state 2 wc'. See earlier patch for motivation.

generate-working-copy-states: generalize for depth The script can currently generate filenames and contents for exactly two changesets plus the working copy. For some tests (e.g. of plain dirstate status), only one changeset is needed, while for others (e.g. merge), three changesets are needed. Let's prepare for such tests by generalizing the code for any number of changesets.

generate-working-copy-states: make 'tracked' a string The only places the 'tracked' variable is only used is where it's converted to a string, so let's simplify by using the string value directly.

merge: demonstrate that directory renames can lose local file content When a directory has been renamed on the local branch and a file has been added in the old location on a remote branch, we move that new file to the new location. Unfortunately, if there is already a file there, we overwrite it with the contents from the remote branch. For untracked local files, we should probably abort, and for tracked local files, we should merge the contents. To start with, let's add a test to demonstrate the breakage. Also note that while files merged in from a remote branch are normally (and unintuitively) reported as modified, these files are reported as added.

mq: drop updateheader - inserthgheader and insertplainheader is enough

mq: smarter handling of plain headers 6333412245ec and 5ccced6eab0b fixed issue4453 with a simple insertplainheader function that fixed the regression but didn't make the implementation more stable. Now we introduce plain header handling similar to how we handle hg patches. The whole header is scanned for fields to update while determining the best position for inserting the field if it is missing. It also makes sure there is an empty line between headers and body.

largefiles: drop the override for 'fetch' The fetch extension has been calling cmdutil.bailifchanged() since a014fdc97154, so this is redundant. Add test coverage to prevent regression. It doesn't look like there is any testing for fetch with largefiles.

rebase: ignore negative state when updating back to original wc parent The state mapping also contains some magic negative values (detached parent, ignored revision). Blindly reading the state thus lead to unfortunate usage of the negative value as an update destination. We now filter them out. We do a minor alteration of the test to catch this.

bundle2-push: provide transaction to reply unbundler This patch series is intended to allow bundle2 push reply part handlers to make changes to the local repository; it has been developed in parallel with an extension that allows the server to rebase incoming changesets while applying them. This diff adds an experimental config option "bundle2.pushback" which provides a transaction to the reply unbundler during a push operation. This behavior is opt-in because of potential security issues: the response can contain any part type that has a handler defined, allowing the server to make arbitrary changes to the local repository.

bundle2.processbundle: let callers request default behavior This patch series is intended to allow bundle2 push reply part handlers to make changes to the local repository; it has been developed in parallel with an extension that allows the server to rebase incoming changesets while applying them. The default transaction getter for processbundle is a private function that raises an exception; this diff lets calling code pass None as the transaction getter to explicitly request this default behavior. The next diff will check a config option to determine whether to provide a transaction to the reply bundle processor. If one shouldn't be provided, the code needs a way to specify that the default behavior should be used.

push: elevate phase transaction to cover entire operation This patch series is intended to allow bundle2 push reply part handlers to make changes to the local repository; it has been developed in parallel with an extension that allows the server to rebase incoming changesets while applying them. Most pushes already open a transaction in order to sync phase information. This diff replaces that transaction with one that spans the entire push operation. This transaction will be used in a later patch to guard repository changes made during the reply handler.

pull: extract transaction logic into separate object This patch series is intended to allow bundle2 push reply part handlers to make changes to the local repository; it has been developed in parallel with an extension that allows the server to rebase incoming changesets while applying them. Aside from the transaction logic, the pulloperation class is used primarily as a logic-free data structure for storing state information. This diff extracts the transaction logic into its own class that can be shared with push operations.

record: don't honor format-changing diffopts (issue4459) record does support the whitespace options, so honor those. In upcoming patches we'll replace all the other uses.

patch.difffeatureopts: add a feature for format-changing diffopts Typically, callers that are interested in this set are also interested in the others. We still add it as a first-class flag for convenience.

patch.difffeatureopts: add a feature for whitespace diffopts These aren't exactly format-breaking features -- just ones for which patches applied to a repo will produce incorrect commits, In any case, some commands like record and annotate only care about this feature.

patch.difffeatureopts: add a feature for diff.git This deserves to be its own feature -- indeed, this is often the only feature several commands care about.

patch: rename diffopts to diffallopts This is meant to be used when all features are explicitly requested. diffopts is kept as an alias for now -- it will go away soon.

patch: add a new function to initialize diffopts by feature Not all callers are interested in all diffopts -- for example, commands like record (which use diff internally) break when diffopts like noprefix are enabled. This function will allow us to add flags that callers can use to enable only the features they're interested in.

patch.diffopts: use a dict for initialization In upcoming patches we'll conditionally add to and remove from the dict.

largefiles: split the creation of a normal matcher out of its install method Refactoring addremove to support subrepos will need the ability to keep passing the same matcher and narrowing it, instead of monkey patching scmutil's matcher.

addremove: print relative paths when called with -I/-X (BC) For "hg addremove 'glob:*.py'", we print any paths added or removed as relative to the current directory, but when "hg addremove -I 'glob:*.py'" is used, we use the absolute path (relative from the repo root). It seems like they should be the same, so change it so we use relative paths in both cases. Continue to use absolute paths when no patterns are given.
