Now that we have the machinery of namespaces in-place, we use that instead of
hand-rolling our own template function.
Note, this can only be used for tags because both branches and bookmarks have
special case logic for 'default' and the current bookmark (which is something
outside the namespace api for now).
When looking for untracked files that would conflict with a tracked
file in the target revision (or the remote side of a merge), we
explcitly exclude ignored files. The code was added in f1db75422e70
(merge: refactor unknown file conflict checking, 2012-02-09), but it
seems like only unknown, not ignored, files were considered since the
beginning of time.
Although ignored files are mostly build outputs and backup files, we
should still not overwrite them. Fix by simply removing the explicit
check.
We don't seem to have any tests for updating to another revision when
there are untracked files on the local side that conflict with the
those on the remote side, so let's add tests. This shows how we
overwrite untracked ignored files when updating to a revision that
tracks the file.
The state mapping also contains some magic negative values (detached
parent, ignored revision). Blindly reading the state thus lead to
unfortunate usage of the negative value as an update destination. We
now filter them out.
We do a minor alteration of the test to catch this.
Before, merging would in some cases ask "wrong" questions about
"changed/deleted" conflicts ... and even do it before the resolve phase where
they can be postponed, re"resolved" or answered in bulk operations.
Instead, check that the content of the changed file really did change.
Reading and comparing file content is expensive and should be avoided before
the resolve phase. Prompting the user is however even more expensive. Checking
the content here is thus better.
The 'f in ancestors[0]' should not be necessary but is included to be extra
safe.
Use suffix -same for cases where file changed but content is the same - that is
the case where manifestmerge doesn't detect that a file is unchanged.
(The suffix -id is already used for cases where the file didn't change - that
is the trivial case where manifestmerge detects that the file is unchanged.)
These new tests are good but the results are bad. There shouldn't be any merge
conflicts or prompts when one side didn't change.
This allow to gracefully report the failure of the bookmark push and carry on.
Before this change set. Local push would plain quit and wireprotocol would
failed in various ungraceful way.
We need to gracefully handle some aborts for pushkey, especially
because it leads to a user-facing crash over the wireprotocols. So we
need a more specialized exception to catch.
Mq tried to insert headers in the right order. Sometimes it would stop
searching before checking all headers and it could thus duplicate a header
instead of replacing it.
This patch fixes a bug where hgweb would send an incomplete HTTP
response.
If an uncaught exception is raised when hgweb is processing a request,
hgweb attempts to send a generic error response and log that exception.
The server defaults to chunked transfer coding. If an uncaught exception
occurred, it was sending the error response string / chunk properly.
However, RFC 7230 Section 4.1 mandates a 0 size last chunk be sent to
indicate end of the entity body. hgweb was failing to send this last
chunk. As a result, properly written HTTP clients would assume more data
was coming and they would likely time out waiting for another chunk to
arrive.
Mercurial's own test harness was paving over the improper HTTP behavior
by not attempting to read the response body if the status code was 500.
This incorrect workaround was added in faced8f5c2af and has been removed
with this patch.
The result of 'hg rm' + 'hg rename' disagreed with the one from
'hg rename --force'. We align them on 'hg move --force' because it agrees with
what 'hg status' says after the commit.
Stopping reporting a modified file as added puts an end to the hg revert confusion in this
situation (issue4458).
However, reporting the file as modified also prevents revert from restoring the copy
source. We fix this in a later changeset.
Git diff also stop reporting the add in the middle of the chain as add. Not
sure how important (and even wrong) it is.
Because the same dictionary was used to (1) get node from parent and (2) store
annotated version, we could end up with buggy values. For example with a chain
of renames:
$ hg mv b c
$ hg mv a b
The value from 'b' would be updated as "<old-a>a", then the value of c would be
updated as "<old-b>a'. With the current dictionary sharing this ends up with:
'<new-c>' == '<old-a>aa'
This value is double-wrong as we should use '<old-b>' and a single 'a'.
We now use a read-only value for lookup. The 'test-rename.t' test is impacted
because such a chained added file is suddenly detected as such.
Changeset 5b64e22ecd8e introduced the examination of exec bit of
largefiles in "hg status --rev REV" case, but it doesn't avoid it on
the platform being unaware of exec-bit (e.g. on NTFS of Windows).
Previously, if reorder was true during the creation of a changegroup bundle,
it was possible that the manifest and filelogs would be reordered such that the
resulting bundle filelog had a linkrev that pointed to a commit that was not
the earliest instance of the filelog revision. For example:
With commits:
0<-1<---3<-4
\ /
--2<---
if 2 and 3 added the same version of a file, if the manifests of 2 and 3 have
their order reversed, but the changelog did not, it could produce a filelog with
linkrevs 0<-3 instead of 0<-2, which meant if commit 3 was stripped, it would
delete that file data from the repository and commit 2 would be corrupt (as
would any future pulls that tried to build upon that version of the file).
The fix is to make the linkrev fixup smarter. Previously it considered the first
manifest that added a file to be the first commit that added that file, which is
not true. Now, for every file revision we add to the bundle we make sure we
attach it to the earliest applicable linkrev.
"/search", which is an invalid command in hgweb, was mistakenly used for
"[show] more [revsets]" and "[show] less [revsets]" links on search page in
templates "paper" (and those which inherit paper, such as coal) before and
worked fine until 73c8d0c02c22, which made hgweb more strict about invalid
commands.
The phase-syncing code was using bundle2 if the remote supported it. It was
doing so without regard to bundle2 activation on the client. Moreover, the
phase push is now properly included in the unified bundle2 push, so having extra
code in syncphase should be useless. If the remote is bundle2-enabled, the
phases should already be synced.
The buggy verification code was leading to a crash when a 3.2 client was pushing
to a 3.1 server. The real bundle2 path detected that their versions were
incompatible, but the syncphase code failed to, sending an incompatible bundle2
to the server.
We drop the useless and buggy code as a result. The "else" clause is
de-indented in the process.
Fix inconsistent handling of plain header separation in mq patcheader - and
contrary to 05acc6157816, do it in the direction of having an empty line
between header and description. Plain patches are like mails and should thus
have an empty line between headers and body in compliance with RFC 822 3.1.
The new rebase revset didn't check for the case when there are no common
ancestors. Now it does. The new behavior should be the same as the pre-3.2
behavior. Added a test.
simplejson produces slightly different output from the built-in json
module, specifically:
* It uses 0.000 instead of 0.0000
* It likes to put a trailing space after a comma
This change works around both of those variations.
A matcher is required when enabling the subrepo option on archival.archive(),
because that calls match.narrowmatcher(), which accesses fields on the object.
It's therefore probably a bad idea to default the matcher to None on archive(),
but that's a fix for default.
Previously, fnodes had a key and empty dict value for every element in
changedfiles. This is somewhat wasteful. Empty dicts in CPython consume
a lot more memory than you would expect - 280 bytes.
On mozilla-central, which has ~190,000 files/fnodes keys, the previous
loop populating fnodes allocated 91,924 KB of memory, most of that for
the empty dicts.
With this patch in place, our peak RSS during mozilla-central clone
drops:
before: 364,356 KB
after: 326,008 KB
delta: -38,348 KB
When combined with the previous patch, total peak RSS decrease is now
190,116 KB.
The contents of fnodes are only accessed once per key. It is wasteful to
cache the value since nobody will use it.
Before this patch, the caching of unused data in fnodes was effectively
causing a memory leak during the file streaming part of bundle creation.
On mozilla-central (which has ~190,000 entries in fnodes), this patch
has a significant impact on RSS at the end of generate():
before: 516,124 KB
after: 364,356 KB
delta: -151,768 KB
The origin of this code can be traced back to 1f567a607f1f and has been
with us since the 2.7 release.
lookupmf() is currently defined earlier than when it is needed. Future
patches further refactoring this code will be easier to read when
lookupmf() is in its new home.
The mail module only verifies the smtp ssl certificate if 'verifycert' is enabled
(the default). The 'verifycert' can take three possible values:
- 'strict'
- 'loose'
- any "False" value, eg: 'false' or '0'
We tested the validity of the third value, but never converted it to actual
falseness, making 'False' an equivalent for 'loose'.
This changeset fixes it.
2ec3e28dea6b changed 'sample' from a list to a set. The iteration order is thus
undefined and the yesno indices are not stable.
To solve this, repeat the listification and comment from elsewhere in the code.
Note: the randomness in the discovery protocol can make this problem hard to
reproduce.
2ec3e28dea6b made it possible that the initial head check didn't include all
heads. If that is the case, don't use the early exit just because this random
sample happened to be 'all known'.
Note: the randomness in the discovery protocol can make this problem hard to
reproduce.
This keyword remapping was introduced in 236440938a03 as part of converting
generator based iterators into list based iterators, mentioning "undesired
behavior in template" when a generator is exhausted, but doesn't say what and
introduces no tests.
The problem with the remapping was that it corrupted the output for keywords
like 'extras', 'file_copies' and 'file_copies_switch' in templates such as:
$ hg log -r 82a4f5557c6b --template "{file_copies % ' File: {file_copy}\n'}"
File: mercurial/changelog.py (mercurial/hg.py)
File: mercurial/changelog.py (mercurial/hg.py)
File: mercurial/changelog.py (mercurial/hg.py)
File: mercurial/changelog.py (mercurial/hg.py)
File: mercurial/changelog.py (mercurial/hg.py)
File: mercurial/changelog.py (mercurial/hg.py)
File: mercurial/changelog.py (mercurial/hg.py)
File: mercurial/changelog.py (mercurial/hg.py)
What was happening was that in the first call to runtemplate() inside runmap(),
'lm' mapped the keyword (e.g. file_copies) to the appropriate showxxx() method.
On each subsequent call to runtemplate() in that loop however, the keyword was
mapped to a list of the first item's pieces, e.g.:
'file_copy': ['mercurial/changelog.py', ' (', 'mercurial/hg.py', ')']
Therefore, the dict for the second and any subsequent items were not processed
through the corresponding showxxx() method, and the first item's data was
reused.
The 'extras' keyword regressed in 56b014c52204, and 'file_copies' regressed in
4e182fb53989 for other reasons. The common thread of things fixed by this seems
to be when a list of dicts are passed to the templatekw._hybrid class.
For any namespace, we generate a template keyword. For example, given a
namespace 'babar', we automatically have the ability to use it in a template:
hg log -r . -T '{babars % "King: {babar}\n"}'
Furthermore, we only generate this keyword for a namespace if one doesn't
already exist. This is necessary for 'branches' and 'bookmarks' since both of
those have concepts of 'current' (something outside the namespace api) and also
allows extensions to override default behavior if desired.
This marks our second feature of the namespace api: automatic template keyword.
This patch adds a method that takes in a namespace and uses the node-to-name
map to output the list of names.
This patch adds a node-to-name map property to the namespace. This is necessary
because we cannot simply invert the name-to-node map because we do not assume
the name-to-node map to be unique (for example, consider named branches: many
nodes have one branch name).
The node-to-name is helpful in log commands where we are already iterating over
a set of nodes and want to display some kind of naming information to the user.
This patch adds the public api for getting the template name of a namespace so
that the next patch can use it to generate a template keyword automatically.
The template name property will be used in upcoming patches to automatically
generate a template keyword. For example, given a namespace called 'babars', we
will automatically generate a template keyword 'babar' such that we can use it
in the following way,
$ hg log -r . -T '{babars % "King: {babar}\n"}'
Because:
- the test to avoid regression for issue4470 was already added to
test-commit-amend.t by previous patch
It is also a part of test series about manifest calculation issues
of memctx in test-commit-amend.t.
- this is the only test using "commit --amend" in test-commit.t
