In my patch series ending with rev 25e4b2f000c5 I switched most change/delete conflicts to be handled at the resolve layer. .hgsubstate was the one file that we weren't able to handle, so we kept the old code path around for it. The old code path added .hgsubstate to one of the other lists as the user specifies, including possibly the 'g' list. Now since we did this check after converting the actions from being keyed by file to being keyed by action type, there was nothing that actually removed .hgsubstate from the 'cd' or 'dc' lists. This meant that the file would eventually make its way into the 'mergeactions' list, now freshly augmented with 'cd' and 'dc' actions. We call subrepo.submerge for both 'g' actions and merge actions. This means that if the resolution to an .hgsubstate change/delete conflict was to add it to the 'g' list, subrepo.submerge would be called twice. It turns out that this doesn't cause any adverse effects on Linux due to caching, but apparently breaks on other operating systems including Windows. The fix here moves this to before we convert the actions over. This ensures that it .hgsubstate doesn't make its way into multiple lists. The real fix here is going to be: (1) move .hgsubstate conflict resolution into the resolve layer, and (2) use a real data structure for the actions rather than shuffling data around between lists and dictionaries: we need a hash (or prefix-based) index by file and a list index by action type. There's a very tiny behavior change here: collision detection on case-insensitive systems will happen after this is resolved, not before. I think this is the right change -- .hgsubstate could theoretically collide with other files -- but in any case it makes no practical difference. Thanks to Yuya Nishihara for investigating this.

We've discovered an issue with this flag during certain kinds of rebases. When: (1) we're rebasing while currently on the destination commit, and (2) an untracked or ignored file F is currently in the working copy, and (3) the same file F is in a source commit, and (4) F has different contents in the source commit, then we'll try to merge the file rather than overwrite it. An earlier patch I sent honored the options for these situations as well. Unfortunately, rebases go through the same flow as the old, deprecated 'hg merge --force'. We'd rather not make any changes to 'hg merge --force' behavior, and there's no way from this point in the code to figure out whether we're in 'hg rebase' or 'hg merge --force'. Pierre-Yves David and I came up with the idea to split the 'force' flag up into 'force' for rebases, and 'forcemerge' for merge. Since this is a very disruptive change and we're in freeze mode, simply undocument the options for this release so that our hands aren't tied by BC concerns. We'll redocument them in the next release.

Before this patch, "hg pull --update" doesn't advance current active bookmark correctly, if pulling itself doesn't advance it, even though "hg pull" + "hg update" does so. Existing test for "pull --update works the same as pull && update" in test-bookmarks.t doesn't examine this case, because pulling itself advance current active bookmark before actual updating the working directory in that test case. To advance current active bookmark at "hg pull --update" correctly, this patch examines 'movemarkfrom' instead of 'not checkout'. Even if 'not checkout' at the invocation of postincoming(), 'checkout' is overwritten by "the revision to update to" value returned by destutil.destupdate() in such case. Therefore, 'not checkout' condition means "update destination is revision #0", and isn't suitable for examining whether active bookmark should be advanced. Even though examination around "movemarkfrom == repo['.'].node()" may seem a little redundant just for this issue, this makes it easier to compare (and unify in the future, maybe) with the same logic to update bookmark at "hg update" below. if not ret and movemarkfrom: if movemarkfrom == repo['.'].node(): pass # no-op update elif bookmarks.update(repo, [movemarkfrom], repo['.'].node()): ui.status(_("updating bookmark %s\n") % repo._activebookmark) else: # this can happen with a non-linear update ui.status(_("(leaving bookmark %s)\n") % repo._activebookmark) bookmarks.deactivate(repo)

Previously, if the largefile was deleted at the time of a commit, the standin was silently not updated and its current state (possibly garbage) was recorded. The test makes it look like this is somewhat of an edge case, but the same thing happens when an `hg revert` followed by `rm` changes the standin. Aside from the second invocation of this in lfutil.updatestandinsbymatch() (which is what triggers this test case), the three other uses are guarded by dirstate checks for added or modified, or an existence check in the filesystem. So aborting in lfutil.updatestandins() should be safe, and will avoid silent skips in the future if this is used elsewhere.

There were two mistakes: one was accidental reuse of the fclnode variable from the loop gathering file nodes, and the other (masked by that bug) was not correctly handling deleted directories. Both cases are now fixed and the test passes.

On repos with lots of heads, the filelog() code could spend several minutes decompressing manifests. This change instead tries to efficiently scan the changelog for candidates and decompress as few manifests as possible. This is a regression introduced in 3.3 by the linkrev adjustment code. Prior to that, filelog was nearly instant. For the repo in the bug report, this improves time of a simple log command from ~3 minutes to ~.5 seconds, a 360x speedup. For the main Mercurial repo, a log of commands.py slows down from 1.14s to 1.45s, a 27% slowdown. This is still faster than the file() revset, which takes 2.1 seconds.

The largefiles extension needs to set lfstatus for this status call. Otherwise, if a missing largefile is explicitly named, a confusing message is issued that says the largefile wasn't found, followed by another that says nothing changed.

The change in b68797f244e4 to handle a normal -> largefile switch was too aggressive in preserving the original matcher names. If a largefile is explicitly provided by the user, but only the standin exists in dirstate, then only the standin can be committed. There's still maybe an issue when the largefile is deleted outside of Mercurial: $ rm large $ hg ci -m "oops" large large: The system cannot find the file specified nothing changed [1]

In 81b391a45264 (context: clarify why we don't compare file contents when nodeid differs, 2016-01-12), I also changed "node2 != _newnode" into "self.rev() is not None". I don't remember why. They are similar, but the former also catches the case where the file is clean in the dirstate (so node2 is not _newnode), but different from the "other" context. This resulted in unnecessary file content comparison a few lines further down in the code. Let's just back out the code change. Thanks to Durham Goode for spotting this.

In this case, a template is parsed recursively with no thunk for lazy evaluation. This patch prevents recursion by putting a dummy of the same name into a cache that will be referenced while parsing if there's a recursion. changeset = {files % changeset}\n ~~~~~~~~~ = [(_runrecursivesymbol, 'changeset')]

It would be nice if we could detect recursion at the parsing phase, but we can't because a template can refer to a keyword of the same name. For example, "rev = {rev}" is valid if rev is a keyword, and we don't know if rev is a keyword or a template while parsing.

In 5c0fd878779c (treemanifests: set bundle2 part parameter indicating treemanifest, 2016-01-08), I didn't realize I had to set the parameter separately for getbundle and unbundle. Having the parameter there on push allows us to push to an empty repo and have the requirements updated correctly.

Before this patch, the help bar in crecord wouldn't be printed correctly when the terminal window didn't have enough column to display it. This patch adds logic to make sure that the help bar message is always displayed. We use an ellipsis when it is not possible to display the complete message.

In the crecord help dialog, the toggle all option was wrongfully documented. Instead of using 'a', one must use 'A' to toggle all the hunks. The crecord header that is always displayed on the screen contains the right shortcut and does not need to be changed.

This patch improves the error messages raised when an OSError occurs, since simply re-raising the exception can be both confusing and misleading. For example, if "hg identify" is run inside a repository that contains a Git subrepository and the git binary could not be found, it'll exit with the message "abort: No such file or directory". That implies "identify" has a problem reading the repository itself. There's no way for the user to know what the real problem is unless they dive into the Mercurial source, which is what I ended up doing after spending hours debugging errors while provisioning a VM with Ansible (turns out I forgot to install Git on it). Descriptive errors are especially important on Windows, since it's common for Windows users to forget to set the "Path" system variable after installing Git.

After 91ac8cb79125 graph canvas width is decided once on the initial rendering. However, after graph page gets scrolled down to load more, it might need more horizontal space to draw, so it needs to resize the canvas dynamically. The exact problem that this patch solves can be seen using: hg init testfork cd testfork echo 0 > foo hg ci -Am0 echo 1 > foo hg ci -m1 hg up 0 echo 2 > foo hg ci -m2 hg gl -T '{rev}\n' @ 2 | | o 1 |/ o 0 hg serve And then by navigating to http://127.0.0.1:8000/graph/tip?revcount=1 "revcount=1" makes sure the initial graph contains only revision 2. And because the initial canvas width takes only that one revision into count, after the (immediate) AJAX update revision 1 will be cut off from the graph. We can safely set canvas width to the new value we get from the AJAX request because every time graph is updated, it is completely redrawn using all the requested nodes (in the case above it will use /graph/2?revcount=61), so the value is guaranteed not to decrease. P.S.: Sorry for parsing HTML with regexes, but I didn't start it.

Laurent's commit 3203dfe341f9 still suffers from a race: by the time the "job" function tries to assign to channels[channel], that list has been truncated to empty. The result is that every job thread raises an IndexError. Earlier, I tried an approach of correctly locking channels, but that caused run-tests to hang on KeyboardInterrupt sometimes. This approach is strictly hackier, but seems to actually work reliably.

Similar to previous change, this teaches shelve to pick the right changegroup version for repos that use treemanifests.
-
Martin von Zweigbergk authored
The newly created helper changegroup.safeversion() knows to pick version 03 if the repo uses treemanifests, so just using that means we pick the right changegroup version.
-
Martin von Zweigbergk authored
In a few places (at least repair.py and shelve.py), we want to find the best changegroup version that we can assume users of the repo will understand. For example, we choose version 01 by default, but if it's a generaldelta repo, we expect clients to support version 02 anyway, so we choose that for new bundles (for e.g. "hg strip"). Let's create a helper for this functionality in changegroup, so we can reuse it elsewhere later.

Since it would be terribly expensive to convert between flat manifests and treemanifests, we have decided to simply not support changegroup version 01 and 02 with treemanifests. Therefore, let's stop announcing that we support these versions on treemanifest repos. Note that this means that older clients that try to clone from a treemanifest repo will fail. What happens is that the server, after this patch, finds that there are no common versions and raises "ValueError: no common changegroup version". This results in "abort: HTTP Error 500: Internal Server Error" on the client. Before this patch, it was no better: The server would instead find that there were directory manifest nodes to put in the changegroup 01 or 02 and raise an AssertionError on changegroup.py#668 (assert not tmfnodes), which would also appear as a 500 to the client.

Before this patch, it was possible for run-tests to crash on a race condition. The race condition happens in the following case: - the last test finishes and calls: done.put(None) - the context switches to the main thread that clears the channels list - the context switches to the last test mentioned above, it tries to access channels[channel] and crashes This happened to me while running run-tests. This patch fixes the issue by clearing the channel before considering that the test is done.

changegroup.getchunks() determines the end of the stream by looking for an empty chunk group (two consecutive empty chunks). It ignores empty groups in the first two groups. Changegroup 3 introduced an empty chunk between the manifests and the files, which confuses getchunks(). Since it comes after the first two, getchunks() will stop there. Fix by rewriting getchunks so it first counts two groups (empty or not) and then keeps antostarts counting empty groups. With this counting, changegroup 1 and 2 have exactly one empty group after the first two groups, while changegroup 3 has two (one for directories and one for files). It's a little hard to test this at this point, but I have verified that this patch fixes narrowhg (which was broken before this patch). Also, future patches will fix "hg strip" with treemanifests, and once that's done, getchunks() will be tested through tests of "hg strip".

Before this patch if the hiddencache existed but was empty, it would crash mercurial. This patch adds exception handling when reading the hiddencache to avoid the issue. When encountering a corrupted cache file we print a devel warning. There would be no point in issuing a normal warning as the user wouldn't be able to do anything about the situation. The warning looks like: devel-warn: corrupted hidden cache, removing it at: /path/to/repoview.py

These operations are obviously invalid for file-like channels because they will read or write protocol headers. This patch works around the issue that "hg archive" generates a corrupted zip file on Windows commandserver because of unusable tell() implementation. But the problem still occurs without using a commandserver. $ hg archive -R not-small-repo -t zip - | cat > invalid.zip So, this patch cannot fix the issue5049 completely.

Before this patch, template files for "graph" web page use fixed width size "480" for canvas element. This causes pruned lanes and invisible vertexes, if there are 16 or more vertical lanes at once. In such case, part of graph in right side area over 480 is invisible, even though corresponded summary text blocks are visible correctly. This limitation isn't reasonable for workflow using many branches at once (e.g. "one branch per issue" workflow). There were changes below related to width of canvas: - 7359cb753a54 (templates: widen the graph canvas (issue2683)), released as a part of Mercurial 1.8.2 According to the description, this assumed that 15 parallel branches was enough for ordinary workflow, and bumped width of canvas up from 224 to 480. - d490edc71146 (hgweb: make graph data suitable for template usage), released as a part of Mercurial 2.3 This introduced "canvaswidth" template keyword as a part of refactoring around graph rendering. But 'width="480"' of canvas element in template files wasn't replaced by 'width="{canvaswidth}"' in it (or subsequent one). This patch uses dynamic value "{canvaswidth}" instead of fixed width size "480" for canvas element. This is posted for "stable", because: - this is re-fixing issue2683 - this is simple enough for stable - using "{canvaswidth}" doesn't require any additional cost Calculation of canvaswidth is already implied as a part of "graph" web command.
