* vc-dir and Bazaar @ 2010-07-23 12:03 Stephen Berman 2010-07-23 21:32 ` Óscar Fuentes 0 siblings, 1 reply; 10+ messages in thread From: Stephen Berman @ 2010-07-23 12:03 UTC (permalink / raw To: help-gnu-emacs The Emacs manual (32.1 Version Control) says: "The Emacs version control interface is called VC. Its commands work with several different version control systems; currently, it supports GNU Arch, Bazaar, [...]" and (32.1.6 VC Directory Mode): "The VC Directory buffer works with all the version control systems that VC supports." But when I type `C-x v d' (vc-dir) and at the prompt enter the directory of my bzr Emacs trunk tree, all I get is this: =============== VC backend : Bzr Working dir: /data/steve/bzr/emacs/trunk/ Parent branch : http://bzr.savannah.gnu.org/r/emacs/trunk/ Shelves : No shelved changes ./ =============== No files are listed, although the parent branch contains changes against my working directory. And when I type `+' (vc-update), all I get is the message from vc-call-backend: "Sorry, merge-news is not implemented for Bzr". (I don't understand the message; I thought I was invoking update, not merge or merge-news, whatever that is.) So does vc-dir not work with bzr, contrary to the manual, or do I need to do something else? I have no problem using bzr from the command line, updating the trunk, merging, etc. This is with Bazaar (bzr) 2.1.0 Python interpreter: /usr/bin/python 2.6.2 Python standard library: /usr/lib/python2.6 Platform: Linux-2.6.31.12-0.2-default-i686-athlon-with-SuSE-11.2-i586 bzrlib: /usr/lib/python2.6/site-packages/bzrlib Bazaar configuration: /home/steve/.bazaar Bazaar log file: /home/steve/.bzr.log and GNU Emacs 24.0.50.1 (i686-pc-linux-gnu, GTK+ Version 2.18.6) of 2010-07-18 on escher I'd be grateful for any help.

The commands pointed out by Óscar usually make sense on so-called "interesting" files -- those you have uncommitted changes for, those that were not add to the VC, etc. And vc-dir is documented to show only those "interesting" files. In your case, evidently there are none. IOW, before you can meaningfully use vc-dir, you need to do something worthy of it ;-) E.g., modify some file. ^ permalink raw reply [flat|nested] 10+ messages in thread

So, since my Emacs trunk tree is a mirror of the Savannah trunk and I only update it, I can't use vc-dir to do this. Moreover, I can't use it to merge the updated files from the trunk to my quickfixes branch. But once I have merged them from the command line, I can see them vc-dir (I just did this and do see them). So now I should be able to commit the merged files, right? I type `M' to mark all the files, then `v', then a log buffer pops, I write "Merge from trunk", type `C-c C-c' and get: "bzr: ERROR: Selected-file commit of merges is not supported yet: files ChangeLog, configure, configure.in, lisp/ChangeLog, lisp/play/tetris.el, lisp/progmodes/ps-mode.el, src/ChangeLog, src/alloc.c, src/font.c, src/frame.c, src/ralloc.c, src/w32menu.c" Does that mean I can only commit single files?

Yes, but more importantly, you can commit _all_ of the pending merges if you just don't mark any files. That's what you should do most of the time anyway, this being a changeset-based VCS, right? > I think the manual should document these limitations. The manual doesn't like to mention limitations of a temporary nature, because they are expected to be solved in some future release.

Why "merge-news" instead of simply "merge"? Is there a difference? The former term sounds strange and is confusing in a UI error message. >> But once I have merged them from the command line, I can see them vc-dir >> (I just did this and do see them).

That did what I wanted; but after it executed, I got this message: "vc-do-command: Running bzr status admin/nt/makedist.bat...FAILED (status 3)" and the *vc-dir* buffer showed all the files as uncommitted that it displayed before I had type `v'. But when I refreshed the buffer, it showed only the directories. And when I tried to commit the merged files from the command line, it said there were no changes to commit. So `v' worked in vc-dir despite the error message and the non-updated display. Should I report a bug about that? >> I think the manual should document these limitations. > > The manual doesn't like to mention limitations of a temporary nature, > because they are expected to be solved in some future release.

That's reasonable; yet reading that VC supports Bazaar does lead one to expect full support... Thanks for the feedback. Steve Berman ^ permalink raw reply [flat|nested] 10+ messages in thread

Is there a difference? The "merge-news" method merges recent changes from the current branch. That is different from "merge". You can see the list of all methods in the commentary at the beginning of vc.el. That said, I agree that the message is confusingly technical, especially since these methods are not documented in the manual.

So the failed command was not the one which committed the merged files, it was the "bzr status" command run afterwards to show the results in the *vc-dir* buffer. The error message usually means that some other bzr command was running when "bzr status" was invoked.
