hgweb: move changeset "tags" to a template in map file (gitweb and monoblue) Less duplication and it's also easier to add extra "tags" everywhere at once. These aren't tags as defined `hg help glossary` (hence the quotes), they are simply called that. They include branch name (in different styles if changeset is a head of that branch or not), (actual) tags and bookmarks. Good candidates to add to this list would be changeset phase and obsoletion status.

hgweb: split long lines in gitweb and monoblue (changeset summary and tags)

debugdeltachain: output information about sparse read if enabled

rebase: exclude descendants of obsoletes w/o a successor in dest (issue5300) .. feature:: Let 'hg rebase' avoid content-divergence by skipping obsolete changesets (and their descendants) when they are present in the rebase set along with one of their successors but none of their successors is in destination. In the following example, when trying to rebase 3:: onto 2, the rebase will abort with "this rebase will cause divergence from: 4": o 7 f | | o 6 e | | | o 5 d' | | x | 4 d (rewritten as 5) |/ o 3 c | | o 2 x | | o | 1 b |/ o 0 a By excluding obsolete changesets without a successor in destination (4 in the example above) and their descendants, we make rebase work in this case, thus giving: o 11 e | o 10 d' | o 9 c | o 8 b | | o 7 f | | | | x 6 e (rewritten using rebase as 11) | | | | | x 5 d' (rewritten using rebase as 10) | | | | x | 4 d | |/ | x 3 c (rewritten using rebase as 9) | | o | 2 x | | | x 1 b (rewritten using rebase as 8) |/ o 0 a where branch 4:: is left behind while branch 5:: is rebased as expected. The rationale is that users may not be interested in rebasing orphan changesets when specifying a rebase set that include them but would still want "stable" ones to be rebased. Currently, the user is suggested to allow divergence (but probably does not want it) or they must specify a rebase set excluding problematic changesets (which might be a bit cumbersome). The approach proposed here corresponds to "Option 2" in https://www.mercurial-scm.org/wiki/CEDRebase. We extend _computeobsoletenotrebased() so that it also return a set of obsolete changesets in rebase set without a successor in destination but with at least one successor in rebase set. This 'obsoletewithoutsuccessorindestination' is then stored as an attribute of rebaseruntime and used in _performrebasesubset() to: * filter out descendants of these changesets from the revisions to rebase; * issue a message about these revisions being skipped. This only occurs if 'evolution.allowdivergence' option is off and 'rebaseskipobsolete' is on.

tests: add a couple of 'hg log' calls in test-rebase-obsolete.t It helps understanding tests.

tests: conditionally display obsfate in test-rebase-obsolete log output This helps understanding and debugging.

tests: clarify a comment in test-rebase-obsolete.t

bundlerepo: rename _bundle to _cgunpacker _bundle is really a changegroup unpacker instance. Rename the variable accordingly. Differential Revision: https://phab.mercurial-scm.org/D1379

bundlerepo: assign bundle attributes in bundle type blocks It is a bit wonky to assign the same object to multiple attributes and then possibly overwrite them later. Refactor the code to use a local variable and defer attribute assignment until the final values are ready. This required passing the bundle instance to _handlebundle2part(). The only use of this method I could find is Facebook's treemanifest extension. Since it is a private method, I don't think it warrants an API callout. Differential Revision: https://phab.mercurial-scm.org/D1378

bundlerepo: make bundle and bundlefile attributes private These attributes are implementation details and shouldn't be exposed outside the class. .. api:: bundlerepo.bundlerepository.bundle and bundlerepo.bundlerepository.bundlefile are now prefixed with an underscore. Differential Revision: https://phab.mercurial-scm.org/D1377

bundlerepo: don't assume there are only two bundle classes exchange.readbundle() can return a type that represents a stream clone bundle. Explicitly handle the bundle1 type and raise a reasonable error message for unhandled bundle types. Differential Revision: https://phab.mercurial-scm.org/D1376

bundlerepo: rename arguments to bundlerepository.__init__ To reflect what they actually are. Differential Revision: https://phab.mercurial-scm.org/D1374

bundlerepo: use suffix variable It looks like the refactor in 702a26fec3e2 attempted to establish this method argument but failed to use it. My editor caught it. Differential Revision: https://phab.mercurial-scm.org/D1373

bundlerepo: make methods agree with base class My editor was complaining about mismatches between method signatures. For methods that are implemented, we change arguments to match the base. For those that aren't, we use variable arguments because it shouldn't matter. Differential Revision: https://phab.mercurial-scm.org/D1372
