I'm (ab)using Mercurial to manage thousands of files that change often, but I'd like to be able to view the log (hg log) without having my term filled with all of the filenames that changed on each commit. hg log -q is a little too quiet, since I need to see the descriptions. Is there a flag I'm missing for hg log?
It sounds as if you might have the verbose flag turned on. You can check by running hg showconfig and looking for a line like ui.verbose=true.
There are a few ways you can fix it:
remove that line from the offending configuration file (Mercurial can use several, and they vary by OS: use hg help config to list the possibilities).
override the flag in your repository's .hg\hgrc or your private Mercurial configuration (Mercurial.ini or ~/.hgrc): add the following lines to it:
[ui]
verbose=false
clear the verbose flag on the commandline: hg log --config ui.verbose=false.

I'm trying to use mercurial file sets to add all the files in a directory tree, excluding very large files and any binary files. Cribbing from the mercurial documentation, this command should do it:
hg init
hg add 'set: size("<1M") and not binary()'
However this returns a status code of 0, and hasn't added anything to my new, empty repo. I've tried just 'set: not binary()' and that didn't work either.
The frustrating thing is that although I can google for mercurial file sets, and find lots of examples, I can't find anything to help troubleshoot when it doesn't work!
I don't have a .hgignore file, and it's a fresh empty repo. Mercurial 4.2.2.
The directory where I'm testing this has a couple of artificially created files for the purpose of testing. In my real use case, I inherit a multi-gigbyte tarball of assorted sources and binaries from a client, and I want to get all the sources into mercurial before I start hacking to fix their problems, hence the need to exclude the binaries and large files that otherwise choke mercurial.
Here's my little test script:
#!/bin/sh -ex
dd if=/dev/urandom of=binary_1k bs=1 count=1024
dd if=/dev/urandom of=binary_2M bs=1 count=2097152
echo "This. Is, a SMALL text file." > text_small
hexdump binary_1k > text_1k
hexdump binary_2M > text_2M
ls -lh
file binary_1k
file binary_2M
file text_1k
file text_2M
hg init
hg add 'set: size("<1M") and not binary()'
hg status -a
hg add 'set: not binary()'
hg status -a
hg add 'set: size("<1M")'
hg status -a
At the end of this, each status command reports no files in the repo, and the add commands report no errors.
The problem is that file sets do a query of Mercurial's repository data base, which knows only about files that are part of the repository or have been added.
One solution is to add all, and then to get rid of the files that you don't like, e.g.:
hg forget 'set:size(">1M") or binary()'
This works, because the query also requires recently added files, even if they haven't been committed yet.
Mercurial Queues is about patches, and patches know nothing about file renames. Is this the reason why Mercurial Queues don't support file renames, or am I doing something wrong renaming the file? I have worked on a patch queue modifying just one file called foo. Now I go back to patch 4 and rename the file via hg mv:
hg qpop 4 # Unapply all patches until patch 4.
hg mv foo bar # Rename file and led Mercuial know about it.
hg qrefresh # Should apply changes to unapplied patch 4.
hg qpush -a # Should apply all unapplied patches.
I get the following error:
unable to find 'foo' for patching
1 out of 1 hunks FAILED -- saving rejects to file foo.rej
patch failed, unable to continue (try -v)
patch failed, rejects left in working dir
errors during apply, please fix and refresh 5.diff
So how should I do to handle file renames with Mercurial Queues? Mercurial commits handle file renames for a reason (as without, it would lose the whole history about the editing of the file after renaming).
Update
Just noticed that hg histedit folding changesets and hg collapse also lose the information of file renaming, the file shows up as a new one instead of a renamed one, and I guess this is for the same reason. Seems like collapsing private changesets is not possible in Mercurial without loosing that information?
Update 2
Found out collapsing private changesets without loosing rename information is possible with hg rebase and its --collapse option, e.g. hg rebase -s 5 -d 4 --collapse. The issue that the other commands should sostain rename information is still vacant, but using the hg rebase command there is at least a way to achieve the desired result.
Is this the reason why Mercurial Queues don't support file renames,
no.
or am I doing something wrong renaming the file?
no.
Yes, patches in chain will have troubles, if they was prepared for foo file, but later in will be bar, but due to different reasons: patches are independent, and every and each patch know nothing about changes in others - they work with context, not with sequence of operations in separate patches. You done rename correctly, but this changeset invalidates later changesets, prepared on old content
I push in our repository more big video files, my fault, I did not notice them and forgot to add the folder with the video to ignore file. Now my friends can not upgrade because a shortage of memory (abort: out of memory). How do I remove a video from the master repository? I tried to just delete the folder with the video in /home/hg/project/.hg/ But then do not start updating with an error. Help me pliz and sorry for my english/
See the Mercurial FAQ:
4.14. I committed a change containing nuclear launch codes, how do I delete it permanently?
4.15. I committed a large binary file/files, how do I delete them permanently?
There are some options described on the Editing History page as well.
You:
$ hg rm video.ogv
$ hg ci -m "removed video.ogv"
Other:
$ hg pull your-repository
$ hg update
The HG FAQ merely gives a few vague pointers. Here's how to do it:
Add to your .hgrc:
[extensions]
hgext.convert=
[convert]
hg.saverev=false
Create a filemap of what files you want to remove (myfilemap)
exclude "relative/path/to/file.mp4"
Use hg convert to make a new repo
hg convert --filemap myfilemap myrepo myrepo.new
Now you have the new repo without the excluded files.
I'd like to use TortoiseMerge with Mercurial to resolve conflicts, but its reporting every line in theirs and mine as added as though its not comparing properly
here is my mercurial.ini:
[ui]
merge = TortoiseMerge
[merge-tools]
TortoiseMerge.executable=C:\Program Files\TortoiseSVN\bin\TortoiseMerge.exe
TortoiseMerge.args=/mine:$local /theirs:$other /base:$base -o /merged:$output
I'm using Hg 1.7.5
What's going on?
Update: When using KDiff or BeyondCompare, the base is always empty.
Thanks
Your setup appears correct.
This is symptomatic of having no copy of the file in the base revision, in which case Mercurial acts as if the file was present but empty.
There are a couple ways of figuring out what's going on here. If there are no copies or renames involved, you should be able to simply do:
$ hg log -r "ancestor(p1(), p2())"
..to determine the ancestor of the merge, then:
$ hg manifest -r <rev> | grep <your file>
..to determine if the file was in fact present.
Alternately, you can run 'hg merge --debug' or 'hg update --debug' to see what changeset and file it's choosing for the merge (including rename/copy details).
If you find that the file is present in the common ancestor Mercurial chooses, then you should report a bug (including your debug output) at:
https://www.mercurial-scm.org/wiki/BugTracker
I'm looking for a way to set .hgrc configuration items without actually editing the text file. I'm trying to standardize the setup of the hgrc across multiple developers and I would like a command like
hg --config ui.username=foo
but which also saves that config change into the hgrc file.
It seems like this should be something that should be supported directly in the vanilla hg command, but I can't find it anywhere.
Someone -- either you or Mercurial -- will have to edit the configuration file if you want the config change to be saved :-)
And if you can call Mercurial with
hg --config ui.username=foo
then you should also be able to do
echo '[ui]' >> ~/.hgrc
echo 'username = foo' >> ~/.hgrc
which will save the config change, not matter how the ~/.hgrc file happens to look like (it is okay to have multiple [ui] sections).
Mercurial 3.0 and later has the hg config --edit command that opens an editor with the user config file. Still not quite what you're asking for, but at least this makes it easier to edit the file interactively.
This form:
hg --config ui.username=foo
Doesn't save anything. It sets the value for just the one run.
Also you can use /etc/mercurial/hgrc for system wide settings if that helps anything.
There is an extension that helps with this, https://bitbucket.org/alu/hgconfig/wiki/Home
After installing that hgext, you can do things like this.
% hg showconfig paths
paths.default=ssh://hg#bitbucket.org/alu/hgconfig
% hg config paths.upstream $(hg showconfig paths.default)
% hg config paths.default $(hg showconfig paths.default | sed 's|/alu/|/nassrat/|')
% hg showconfig paths
paths.default=ssh://hg#bitbucket.org/nassrat/hgconfig
paths.upstream=ssh://hg#bitbucket.org/alu/hgconfig
The only gotcha is this overrides the builtin config command, you can either tweak the code to change the command name, or live with it. Fortunately, it probably would not matter if your use case is simply to set and get specific configs.
