How to update hg with ignoring one file - mercurial

When checking hg verify
portfolio/600x600/72.jpg#8: unpacking 346174023f35: revlog decompress error: Error -3 while decompressing data: incorrect data check
And I need update another files except this. Have any command in hg for do this?
for example from version 49 to 50
like this
hg update 50 -ignore portfolio/600x600/72.jpg

Updating to a revision does not support this. However you can revert selected files to a certain revision:
hg revert -rXXX FILENAME
it also supports the --exclude and --include flags, so you could try:
hg revert -r50 --all --exclude portfolio/600x600/72.jpg
Mind: the repository will be a modified state after this, should you commit, the parent will be your currently checked-out revision.

Resolving conflicts: how to accept "their" changes automatically?

When merging conflicting changes using hg merge, Mercurial inserts a set of markers into the files to be merged in my working copy like this:
<<<<<<< local
version = 0.2
=======
version = 0.1
>>>>>>> other
Then I manually edit all files marked as U from a list produced by hg resolve --all -l and then I tell mercurial I have resolved them by hg resolve -m file1 file2 file3 ...
In many situations I would like however accept either my-only or their-only changes on some conflicting files. I am thinking to create two simple sed/awk/whatever scripts named accept-theirs.sh and accept-my.sh or is there any "proper" way to do it?
Use
hg resolve -t internal:other --all
to accept theirs and
hg resolve -t internal:local --all
to accept yours
Try this:
hg merge --tool internal:other

Mercurial: How to compact/combine specified old revisions into one?

I've got a repository. In the middle of its life-cycle I deleted a lot of unnecessary files from it (I decided to keep them unversioned).
hg remove
hg commit
The repo grows bigger and bigger.
And I decided to get rid of old revisions the from initial one to the revision where lot of files were removed (let's name it X).
Other words I want combine these revisions (from the initial to the X) into one initial revision.
But same time to keep the history of the following revisions (X+1, etc..) as they are.
I googled for the solution, but failed.
And found nothing clever than do this:
hg init newrepo
cd oldrepo
hg archive -r X newrepo
hg export -r X+1: -o "~/patches/%R-%h.diff"
cd newrepo
hg commit -A -m 'initial release (after archiving)'
hg import ~/patches/*.diff
And damn it, after few successfully applied patches
I receive:
Hunk #1 FAILED at xxx
Hunk #2 FAILED at xxx
2 out of 2 hunks FAILED -- saving rejects to file xxx.rej
abort: patch failed to apply
What I do wrong?
I've got 1 repo without branches (to be more exact to the revision X all branches were merged).
The second solution was
* hg convert to svn
* hg convert to mercurial from revisiob X+1
Failed with python backtrace (probably it was caused by our repo has about 3K files).
To filter out files from repository, you want to use hg convert (Mercurial to Mercurial) with --filemap argument (see documentation for more details). Keep in mind the affected changeset IDs (and those of all their descendants) will change.
Take a look at the Collapse extension which seems to do what you want.
You can fold changesets with MQ, or use histedit extension

Mercurial - determine where file was removed?

If you do hg log myfile -v you see a list of changesets that the file was modified in.
In our case, in the most recent changeset, the file was removed. But you can't tell this by looking at the verbose (-v) output of hg log. Is there an easy Mercurial command you can use to determine if and when a file has been removed from the repo?
Update: Note that this is on a Windows client, and we are using Mercurial v 1.4.3
Update 2: Appears the answers below would work with a more recent version of Mercurial, however an upgrade isn't in the cards right now. Any other ideas for v 1.4.3 ???
You can check which revision deleted a file (any many other interesting features) using revsets:
hg log -r 'removes(<myfile>)'
Some examples:
hg log -r 'removes(build.xml)' // where build.xml used to be in the current directory
hg log -r 'removes("**/build.xml")' // where build.xml may have been in sub directories
See hg help revsets for details.
The --removed flag should get you what you are looking for:
hg log myfile -v --removed
From the help for hg log:
--removed include revisions where files were removed
This is what I use to list all the deleted files in my repository:
hg log --template "{rev}: {file_dels}\n" | grep -v ':\s*$'

How can I recover a removed file in Mercurial (if at all)?

Accidentally, by using a GUI as opposed to CLI, I removed every file in a Mercurial project.
I recovered with Revert ok and lost some work, which as I have time machine I could easily get back. But is there a way of un-remove/undelete such files? Trawled through the manual and googled but cannot see anything. Any plugins?
I am probably answering my own question here but the files were gone from the directory and were not in the trash to recover so I am assuming Remove is irrevocable?
p.s. I know that hg forget or hg remove -Af will remove without deleting from the directory but my question has to do with the error I made as opposed to cool thinking the action through.
First, use hg grep to find the deleted file you wish to recover. The output of this command will show you the last revision for which the file was present, and the path to the deleted file.
Second, run hg revert -r <revision number> <path to deleted file>
The deleted file will now be in your working copy, ready to be committed back into head.
Quote from comment:
I set up a repository, committed all, Removed and then committed again
If this is the case then you just need to update the working directory to the previous revision:
$ hg update -C -r-2
Note the negative revision number. If the files you deleted aren't in the previous revision, you can find them by using:
$ hg log -v
For Mercurial 1.6 and above
If you know the name of the delete file you can find its revision easily with:
hg log -r "removes('NAME.c')"
This will give you the revision in witch a file called NAME.c (in the root) is deleted.
Then you can revert the file to the previous revision with (like other answers):
hg revert -r <revision number> <path to deleted file>
You can use a file name pattern instead to adapt to what you know, for example you can use **/NAME.c to search in all directories. You can read about it in File Name Patters. And use this link to know about the new revset specifications.
Well this worked for me.
hg revert -r revision pathToTheFile
An addition to the accepted answer - this is faster if you want to undo all removals in a commit. I deleted a large folder with a few hundred files in it and did hg addremove, which was not at all my intent, so had to undo all of those deletes.
Using Find deleted files in Mercurial repository history, quickly? + xargs + tr, revert all revision -3 removals to the version from revision -4:
hg log -r -3 --template "{rev}: {file_dels}\n" | tr ' ' '\n' | xargs hg revert -r -4
Note that this will fail if any of your files have spaces in the name; http://hgbook.red-bean.com/read/customizing-the-output-of-mercurial.html doesn't appear to have any templates where {file_dels} is split by \n at the moment.
You can undo the last commit on a repo with hg rollback. There's only one level of rollback available, so if you did the remove with more than one commit, this won't completely undo your change. This only works on your local repository, so if you've pushed you won't be able to undo it in the remote repo.
You can remove committed revisions using the hg strip command, which is provided by the mq (Mercurial Queues) extension. This should give you back your files.
Make a backup before trying that out, because it will alter Mercurial's database of changesets.
The following worked for me.
hg revert -r <Revision Number> <File Name>
(Optional, to revert all files)
hg revert -r <Revision Number> --all
The below method is straightforward and so stupid that it cannot go wrong.
If you have deleted or renamed multiple files, it will be ok.
hg clone mydirectory mydirectory1
and now you start mc (or Far Manager) and compare what it was vs what it has become.
when it's done, just delete mydirectory1.

How to resolve merging conflicts in Mercurial (v1.0.2)?

I have a merging conflict, using Mercurial 1.0.2:
merging test.h
warning: conflicts during merge.
merging test.h failed!
6 files updated, 0 files merged, 0 files removed, 1 files unresolved
There are unresolved merges, you can redo the full merge using:
hg update -C 19
hg merge 18
I can't figure out how to resolve this. Google search results instruct to use:
hg resolve
but for some reason my Mercurial (v1.0.2) doesn't have a resolve command:
hg: unknown command 'resolve'
How can I resolve this conflict?
To highlight an answer in a comment for Hg 1.1+:
For Hg 1.1+ fix the file by hand and then do
hg resolve -m test.h
to mark the file as merged.
Valid for hg < v1.1 only
There is no need to call any hg commands. Unlike svn, Mercurial does not track conflicted files. If you call hg status, you'll see that the file is simply marked as modified.
Just fix the file by hand and commit.
Tracking conflicts was introduced in Mercurial 1.1, which is a newer version that you are using (you should really upgrade, Mercurial 1.1. was released in December 2008).
In that version you gained the resolve command which works similarly to svn resolve.
As I remember it, Mercurial would leave merge markers (the <<<< and >>>> lines) in your file when there is a conflict, unless you have configured a merge tool. This also applies to newer versions -- I have no merge tool configured and get the merge markers when conflicts occur. I can then manually fix the file and mark it resolved with hg resolve.
