Before updating the actual bookmark update, we can start with updating the way
we check for push race. Checking bookmarks state earlier is useful even if we
still use pushkey. Aborting before the changegroup is added can save a lot of
time.
This new debugcommand prints the capabilities of any remote in a human friendly
way. Improved bundle2 capabilities support will be introduced in the next
changesets.
Mercurial read all data between the base of the chain and the last delta when
restoring content (including unrelated delta). To monitor this, we add data
about the size of the "delta chain span" to debugrevlog.
This will allow us to map repo["ff..."] to workingctx. _partialmatch() will
be updated later. I tried "return wdirrev" in place of raising the exception,
but earlier exception seemed better.
We are about to remove the branchmap cache update in changegroup application.
There is a debug message alongside this update that we do not want to loose. We
move the message beforehand to simplify the test update in the next changeset.
The message move is quite noisy and isolating that noise is useful.
Most tests update are just line reordering since the message is issued at a
later point during the transaction.
After this changes, the message is displayed in more case since local commit
creation also issue it.
That command make sure caches are updated. This is based on
'localrepo.updatecaches' so when we move support for new cache in that function this
command will benefit from it.
Each data entry ("chunk") in a revlog has a type based on the first
byte of the data. This type indicates how to interpret the data.
This seems like a useful thing to be able to query through a debug
command. So let's add that to `hg debugrevlog`.
This does make `hg debugrevlog` slightly slower, as it has to read
more than just the index. However, even on the mozilla-unified
manifest (which is ~200MB spread over ~350K revisions), this takes
<400ms.
We have debug commands for displaying overall revlog statistics
(debugrevlog) and for dumping a revlog index (debugindex). As part
of investigating various aspects of revlog behavior and performance,
I found it important to have an understanding of how revlog
delta chains behave in practice.
This patch implements a "debugdeltachain" command. For each revision
in a revlog, it dumps information about the delta chain. Which delta
chain it is part of, length of the delta chain, distance since base
revision, info about base revision, size of the delta chain, etc. The
generic formatting facility is used, which means we can templatize
output and get machine readable output like JSON.
This command has already uncovered some weird history in
mozilla-central I didn't know about. So I think it's valuable.
The current heuristic for deciding between storing delta and full texts
is based on ratio of (sizeofdeltas)/(sizeoffulltext).
In some cases (for example a manifest for ahuge repo) this approach
can result in extremely long delta chains (~30,000) which are very slow to
read. (In the case of a manifest ~500ms are added to every hg command because of that).
This commit introduces "revlog.maxchainlength" configuration variable that will
limit delta chain length.
Some versions of python 2.4 write ? instead of <module>. Ignore this detail by
a glob.
This fixes a failure spotted on buildbot, existing since this test lines were
introduced 1a6e234bd7c1.
This is often very handy when hacking/debugging.
Calling util.debugstacktrace('hey') from a place in hg will give something like:
hey at:
