Mercurial: Changelog

phabricator: post revisions in ascending topological order (issue6241) The parent in phabricator ends up being the last revision posted, so sorting the user input into ascending order should be enough to preserve the proper relationships. Differential Revision: https://phab.mercurial-scm.org/D7874

doc: fix references to `revset.abstractsmartset` Differential Revision: https://phab.mercurial-scm.org/D7873

fsmonitor: properly handle str ex.msg ex.msg is always a str, since pywatchman uses str for exception messages. This commit removes a b'' from a string compare to avoid types mismatch and adds a coercion to bytes before stuffing the exception message on our local exception type, which uses bytes for the message elsewhere in this file.

verify: allow the storage to signal when renames can be tested on `skipread` This applies the new marker in the lfs handler to show it in action, and adds the test mentioned at the beginning of the series to show that fulltext isn't necessary in the LFS case. The existing `skipread` isn't enough, because it is also set if an error occurs reading the revlog data, or the data is censored. It could probably be cleared, but then it technically violates the interface contract. That wouldn't matter for the existing verify algorithm, but it isn't clear how that will change as alternate storage support is added. The flag is probably pretty revlog specific, given the comments in verify.py. But there's already filelog specific stuff in there and I'm not sure what future storage will bring, so I don't want to over-engineer this. Likewise, I'm not sure that we want the verify method for each storage type to completely drive the bus when it comes to detecting renames, so I don't want to go down the rabbithole of having verifyintegrity() return metadata hints at this point.

lfs: don't skip locally available blobs when verifying The `skipflags` config was introduced in a2ab9ebcd85b, which specifically calls out downloading and storing all blobs as potentially too expensive. But I don't see any reason to skip blobs that are already available locally. Hashing the blob is the only way to indirectly verify the rawdata content stored in the revlog. (The note in that commit about skipping renamed is still correct, but the reason given about needing fulltext isn't.) Differential Revision: https://phab.mercurial-scm.org/D7712

lfs: add a switch to `hg verify` to ignore the content of blobs Trying to validate the fulltext of an external revision causes missing blobs to be downloaded and cached. Since the downloads aren't batch prefetched[1] and aren't compressed, this can be expensive both in terms of time and space. I made this a tri-state instead of a simple bool because there's an existing (undocumented) config to handle this, and it would be weird if `hg verify` were to suddenly start ignoring that config but an `hg recover` initiated verify honors it. Since this uses the same config setting, it too will skip rename verification (which requires fulltext, but not for LFS).
