wireproto: allow direct stream processing for unbundle Introduce a new option server.streamunbundle which starts a transaction immediately to apply a bundle instead of writing it to a temporary file first. This side steps the need for a large tmp directory at the cost of preventing concurrent pushes. This is a reasonable trade-off for many setups as concurrent pushes for the main branch at least are disallowed anyway. The option defaults to off to preserve existing behavior. Change the wireproto interface to provide a generator for reading the payload and make callers responsible for consuming all data. Differential Revision: https://phab.mercurial-scm.org/D2470

verify: drop "revlog" from warning message Not all stores may be backed by revlogs. Switch to a more generic error message. Differential Revision: https://phab.mercurial-scm.org/D3094

store: make file filtering during walk configurable Previously, the walking mechanism assumed the use of revlogs for storage. Making the file filter configurable will enable custom stores to override _walk() so it recognizes additional files. Differential Revision: https://phab.mercurial-scm.org/D3093

simplestore: shore up lookup errors When revisions or nodes can't be resolved, we're expected to raise an error.LookupError. When I ported code from revlog.py, I failed to realize that "LookupError" in that module is aliased to error.LookupError. I thought we were using the builtin LookupError instead. This commit switches us to error.LookupError. It also fixes rev() to raise error.LookupError instead of KeyError. Differential Revision: https://phab.mercurial-scm.org/D3092

tests: extract dumprevlog tests to own file And mark the test as requiring the revlog store. Differential Revision: https://phab.mercurial-scm.org/D3091

tests: skip test-censor.t when using simple store Censor assumes the use of revlogs. Proper censor support for non-revlog storage will require a better abstraction in the storage layer to remove data. Let's skip the censor tests until we have something in place.

templater: deduplicate iterator of overlay mappings

templater: complain about invalid application of '%' operator (BC) Before, '{x % y % z ...}' was silently evaluated as '{x % y}'. We no longer need this hack since the web template bugs was fixed by earlier patches. At this point, the error message may contain '<generator *>', which will be fixed later.

hgweb: fix type of {nav} keyword when linerange filter is active Spotted by making '%' operator check the operand type more strictly. Before, "{nav}" would be evaluated to a lazy "" (empty string) and {"" % x} would yield one empty string.
