bundle2-localpeer: properly propagate the server output on error (
issue4594)
In case of errors, output parts salvaged from the reply bundle need to be
processed for outputting their content. This concludes our quest for fixing
issue4594.
bundle2: add on more layer of exception catching in localrepo.unbundle
We are going to add output related logic in this function. We do the
indentation first to help next changeset readability. We need a new try except
because we want to handle output on any exception, including PushRaced ones.
bundle2-wireproto: properly propagate the server output on error (
issue4594)
In case of errors, output parts salvaged from the reply bundle are re-injected
into the bundle carrying the exception.
We still need to fix the situation for non-wireprotocol push.
bundle2: refactor error bundle creation for the wireprotocol
We want to add output information to the error bundle. Before doing this, we
rework the code to have a single bundler creation and return statement. This
will make the update with the output simpler as only one place will have to be
touched.
bundle2: store the salvaged output on the exception object
The re-handling of output is happening in some 'unbundle' callers. We have to
transmit the output information to this place so we stick it on the exception.
This is the third step in our quest for preserving the server output on error
(
issue4594). We want to be able to copy the output part from the aborted reply
into the exception bundle.
bundle2: add a 'salvageoutput' method on bundle20
This method returns a copy of all 'output' parts added to the bundler.
This is the second step in our quest for preserving the server output on error
(
issue4594). We want to be able to copy the output parts from the aborted reply
into the exception bundle.
The function will be used in a later patch.
bundle2: add a 'copy' method on parts
This is the first step in our quest for preserving the server output on error
(
issue4594). We want to be able to copy the output parts from the aborted reply
into the exception bundle.
The function will be used in a later patch.
hooks: add a 'txnabort' hook
This hook will be called whenever a transaction is aborted. This will make it
easy for people to clean up temporary content they may have created during a
transaction.
help: document the ''HG_TXNID'' environment variable during hooks
We forgot to document the new "transaction ID" mechanism.
match: add a subclass for dirstate normalizing of the matched patterns
This class is only needed on case insensitive filesystems, and only
for wdir context matches. It allows the user to not match the case of
the items in the filesystem- especially for naming directories, which
dirstate doesn't handle[1]. Making dirstate handle mismatched
directory cases is too expensive[2].
Since dirstate doesn't apply to committed csets, this is only created by
overriding basectx.match() in workingctx, and only on icasefs. The default
arguments have been dropped, because the ctx must be passed to the matcher in
order to function.
For operations that can apply to both wdir and some other context, this ends up
normalizing the filename to the case as it exists in the filesystem, and using
that case for the lookup in the other context. See the diff example in the
test.
Previously, given a directory with an inexact case:
- add worked as expected
- diff, forget and status would silently ignore the request
- files would exit with 1
- commit, revert and remove would fail (even when the commands leading up to
them worked):
$ hg ci -m "AbCDef" capsdir1/capsdir
abort: CapsDir1/CapsDir: no match under directory!
$ hg revert -r '.^' capsdir1/capsdir
capsdir1\capsdir: no such file in rev
64dae27060b7
$ hg remove capsdir1/capsdir
not removing capsdir1\capsdir: no tracked files
[1]
Globs are normalized, so that the -I and -X don't need to be specified with a
case match. Without that, the second last remove (with -X) removes the files,
leaving nothing for the last remove. However, specifying the files as
'glob:**.Txt' does not work. Perhaps this requires 're.IGNORECASE'?
There are only a handful of places that create matchers directly, instead of
being routed through the context.match() method. Some may benefit from changing
over to using ctx.match() as a factory function:
revset.checkstatus()
revset.contains()
revset.filelog()
revset._matchfiles()
localrepository._loadfilter()
ignore.ignore()
fileset.subrepo()
filemerge._picktool()
overrides.addlargefiles()
lfcommands.lfconvert()
kwtemplate.__init__()
eolfile.__init__()
eolfile.checkrev()
acl.buildmatch()
Currently, a toplevel subrepo can be named with an inexact case. However, the
path auditor gets in the way of naming _anything_ in the subrepo if the top
level case doesn't match. That is trickier to handle, because there's the user
provided case, the case in the filesystem, and the case stored in .hgsub. This
can be fixed next cycle.

The narrowmatcher class may need to be tweaked when that is fixed.
