bundle2: capture output issue during transaction close We were capturing all output issue during bundle2 processing, and all output issue during transaction rollback in case of failure. However, the output issue during transaction commit was still roaming the land freely. It is now put back in line. This let the user see output from 'pretxnclose' and 'txnclose' (and related) in the right order.

bundle2: also capture hook output during processing External hook used to directly write on stdout and stderr. As a result their output was not captured by the bundle2 processing. This resulted in confusing out of order output on the client side. We are now capturing hooks output in this context.

ui: allow capture of subprocess output We want to capture hooks output during bundle2 processing. For this purpose we introduce a new 'subproc' argument to 'ui.pushbuffer'. When set, the output of sub process created through 'ui.system' will be captured in the buffer too. This will be used in the next changeset.

bundle2: capture transaction rollback message output (issue4614) The output from the transaction rollback was not included into the reply bundle. It was eventually caught by the usual 'unbundle' output capture and sent to the client but the result was out of order on the client side. We now capture the output for the transaction release and transmit it the same way as all other output. We should probably rethink the whole output capture things but this would not be appropriate for stable. The is still multiple cases were output failed to be properly capture, they will be fixed in later changesets.

bundle2: issue remote output as "status" (issue4612) Remote output should be silenced by --quiet. The issue was found while running `test-largefiles-cache.t` so it will get tested once we switch bundle2 by default.

record: edit patch of newly added files (issue4304) I tried to fix this issue in the past and had to revert the fix. This is a second attempt without the regression we found with the first one. record defines special headers (of file) as headers whose hunk are not shown to the user for editing, they are used to represent deleted, moved and new files. Since we want to authorize editing the patch of newly added file we make the newly added file with some content not special anymore. This entails that we have to save their content before applying the backup to be able to revert it if the patch does not apply properly. We reintroduce the test showing that newly added files can be edited and that their content is shown to the user.

record: remove useless line in test Remove a useless line in test to make the next patch cleaner.

revert: apply normallookup on reverted file if size isn't changed (issue4583) Before this patch, reverting a file to the revision other than the parent doesn't update dirstate. This seems to expect that timestamp and/or size will be changed by reverting. But if (1) dirstate of file "f" is filled with timestamp before reverting and (2) size and timestamp of file "f" isn't changed at reverting, file "f" is recognized as CLEAN unexpectedly. This patch applies "dirstate.normallookup()" on reverted file, if size isn't changed. Making "localrepository.wwrite()" return length of written data is needed to avoid additional (and redundant) "lstat(2)" on the reverted file. "filectx.size()" can't be used to know it, because data may be decoded at being written out. BTW, interactive reverting may cause similar problem, too. But this patch doesn't focus on fixing it, because (1) interactive (maybe slow) reverting changes one (or both) of size/timestamp of reverted files in many usecases, and (2) changes to fix it seems not suitable for stable branch.

win32: remove cacert.pem file from Inno Setup installer Duplicate the modification done in 6e38b6fc4123 for wix installer so that CA certificates loading works fine with Python 2.7.9+.

revert: accept just -I/-X without paths or -a/-i (issue4592) 'hg revert -I foo' currently fails with abort: no files or directories specified (use --all to revert all files, or 'hg update 1' to update) It doesn't seem intentional that -I/-X without other paths or --all/--interactive should fail, and it doesn't seem that harmful to allow it either, so let's just do that.
