zsh_completion: add completion of branch names

zsh_completion: fix issue with overlong branch/tag names

bundlerepo: remove old style check of file names The old check is no longer needed: The checked paths will be passed on to filelog.__init__ which will prefix the path with 'data/'. A leading '/' will thus not do any harm. And: The paths will be used by an opener which will use a pathauditor. And finally: The old check did not consider Windows paths and was thus insufficient.

bundlerepo: use revlog._checkhash The error message will mention datafile instead of indexfile.

bundlerepo: store validated deltabase rev in basemap instead of node This avoids some lookups and aligns bundlerepo more with what revlog do.

bundlerepo: use rev instead of node for iteration in revision() Avoids some lookups and avoids using rev while iterating.

bundlerepo: inline inbundle() It didn't make it faster, it didn't make the code smaller, it didn't make the code simpler. -1 is never in basemap.

bundlerepo: drop bundlebase wrapper function for basemap

bundlerepo: remove unused disktiprev attribute

bundlerepo: improve performance for bundle() revset expression Create the set of revision numbers directly instead of creating a list of nodes first.

bundlerepo: fix outdated comment Comment was made invalid by 01ee43dda681.

hgweb: pass repo object to revnav construction For compatibility with changelog filtering we need access to the changelog, a simple nodefunc is not sufficient, only the changelog and repo have access the filteredrevs information. For the filerevnav version, we use an unfiltered changelog. Linkrev is currently broken with filtering and we need some failsafe to prevent traceback. This is the same approach as the one used in 518c1403838f. The use of filectx.changectx() allowed the previous code to use the 518c1403838f hack. This changeset may result in an incorrect behaviors, Navigation link may point to missing revision. However this bad navigation generation is much better than a plain crash

hgweb: introduction a filerevnav subclass It'll be use to implement the file specific behavior.

hgweb: simplify addition of "(0) navigation entry"

hgweb: simplify the handling of empty repo This abstraction have two advantages: - If the revlog is empty, None of the code bellow is relevant, early returns seems a win. - Abtraction of the 'emptiness' check will help later when we stop relying on nodefunc. A bonus, with filtering, a non-empty revlog may not have '0' revision accessible. It'll be easier to handle with the emptiness test in a dedicated function

hgweb: move hex creation into an object method This is clearer and allow later overwrite.

hgweb: pass nodefunc to the revnav object The issue between hgweb and filtering lay in this function. Moving it into the object itself helps to abstract the erroneous bit.

hgweb: move revnavgen into an object For later compatibility with changelog filtering some part of the navigation generation logic will be altered. Those altered part will be different when in the changelog case and in the filelog case. Moving this into an object will allow to use inheritance to override just the part of the logic we need. The aimed logic are for example: - generation of revision 'hex' (different logic for changelog and filelog) - revlog emptyness test - fetching of the first revision of a revlog (may not be 0)

hgweb: `limit` argument is actually `latestonly` renames and enforce The `limit` argument of several generator have only two possible values in practice: 0 and 1. We rename this parameter to `latestonly` and simplify it's handling. The simplification allows us to save fetching of data that we are sure to not consume. Having a function minimal function perimeter will helps future refactoring.

hgweb: add test regarding filtering and hgweb Since 4d1671b39168 hgweb is broken with filtering. This changeset add test that should pass once it is fixed. Test currently broken are commented and will be uncommented by changeset that fix them. The filelog test is currently passing because we already have some hack in core regarding filelog (see 518c1403838f).

get-with-headers: add a --headeronly switch In some case we do not care about the actual rendering.

tests: more comment cleanup related to obsolescence

test: fix in-test comments related to obsolescence The `ui.prevent-unstable` option never made it into core. It always behaves this way when obsolescence feature is enabled. See changesets c5bd753c5bc6, bacf55bd8f90 and 0f5a0a2073a8 for details.

stream_in: write the remote branchcache for a usage as wide as possible Writing cache for unfiltered repo only is barely useful, Most repo user are now at least use the `hidden` filter. This changeset now assigns the remote cache for a filter as low as possible for a wider reuse as possible.

destroyed: update `unserved` branchcache instead Before this changesets the `destroyed` function updated the branchcache for unfiltered repository. As seen in a previous changeset, Read only repo does not cares about the unfiltered repo. We now update it for `unserved`.

destroyed: drop complex branchcache rebuilt logic The strip code used a trick to lower the cost of branchcache update after a strip. However is less necessary since we have branchcache collaboration. Invalid branchcache are likely to be cheaply rebuilt again a near subset of the repo. Moreover, this trick would need update to be relevant in the now filtered repository world. It currently update the unfiltered branchcache that few people cares about. Make it smarter on that aspect would need complexes update of the calling logic So this mechanism is: - Arguably needed, - Currently irrelevant, - Hard to update and I'm dropping it. We now update the branchcache in all case by courtesy of the read only reader. This changeset have a few expected impact on the testsuite are different cache are updated.

branchmap: update cache of 'unserved' filter on new changesets The `commitctx` and `addchangegroup` methods of repo upgrade branchcache after completion. This behavior aims to keep the branchcache in sync for read only process as hgweb. See ee317dbfb9d0 for details. Since changelog filtering is used, those calls only update the cache for unfiltered repo. One of no interest for typical read only process like hgweb. Note: By chance in basic case, `repo.unfiltered() == repo.filtered('unserved')` This changesets have the "unserved" cache updated instead. I think this is the only cache that matter for hgweb. We could imagine updating all possible branchcaches instead but: - I'm not sure it would have any benefit impact. It may even increase the odd of all cache being invalidated. - This is more complicated change. So I'm going for updating a single cache only which is already better that updating a cache nobody cares about. This changeset have a few expected impact on the testsuite are different cache are updated.

tests: make test-hgweb.t output stable Instability introduced in combination of a4d7fd7ad1f7 and e389a25e7e60.

hgweb: ensure _navseq yield strictly increasing numbers This is not hard and allows to drop hack in the customer code.

hgweb: better names for _navseq arguments The old names were misleading.

hgweb: drop recursivity in _navseq This is totally not needed.

hgweb: move the `seq` function out of the revnavgen scope There is not reason for it to be a in there. And this function could use a major reworks.

hgweb: simplify return value creation in for navgen We now have access to better syntax allowing a clearer version.

hgweb: do not access first changeset with a string There is not reason not to use an int

refactoring: use unlinkpath with ignoremissing

docs: "deprecate" checkchanged and checkconflicts in merge-tool configuration These settings were replaced by check=changed and check=conflicts in a912f26777d3. There is no reason to announce two different ways to achieve the same. The old way should be kept but not announced.

tests: run with PYTHONHASHSEED=random Python set and dict iteration order is in principle undefined but usually 'quite stable'. Setting PYTHONHASHSEED=random will make the iteration order more random in Python 2.6.8 and 2.7.3 and where it has been backported. This can thus help spot dependencies on undefined behaviour and prevent future problems.

run-tests: exit cleanly if parallel run is interrupted If interrupted while running with "--jobs N", run-tests asynchronously spewed a bunch of output and backtraces from both the master and slave processes, leaving the terminal full of goop. This patch makes it behave more sensibly.

filtering: rename filters to their antonyms Now that changelog filtering is in place, it's become evident that naming the filters according to the set of revs _not_ included in the filtered changelog is confusing. This is especially evident in the collaborative branch cache scheme. This changes the names of the filters to reflect the revs that _are_ included: hidden -> visible unserved -> served mutable -> immutable impactable -> base repoview.filteredrevs is renamed to filterrevs, so that callers read a bit more sensibly, e.g.: filterrevs('visible') # filter revs according to what's visible

clone: don't include empty revlogs in stream

serve: don't send any content headers with 304 responses Fixes HTTP protocol violation introduced in cf5c76017e11. 'hg serve' would show a stacktrace when loading pages that not had been modified. There was test coverage for this, but the wrong response headers wasn't shown and thus not detected.

tests: fix doctest stability over Python versions pprint ain't pretty in Python 2.4: Changed in version 2.5: Dictionaries are sorted by key before the display is computed; before 2.5, a dictionary was sorted only if its display required more than one line, although that wasn’t documented. Fixes issue introduced in 404feac78b8a.

tests: stabilize doctest output Avoid dependencies to dict iteration order.

tests: make test-hook.t output more stable

convert: make toposort order stable when multiple orderings are possible The output of some tests are changed. Not necessarily to the better, just other valid permutations.

convert: report cvsps branchpoints sorted

convert: process subversion branch in a sorted order

convert: process missing branches in sorted order
