Dear cscope devs, I'm a cscope user who was just browsing your project page and noticed a very long backlog of bug reports, some more than 10 years old. At first I thought the project may have been unmaintained for years, but it seems that's not the case. Are you interested in accepting patches which fix some of those bugs? If so, would you accept a contribution of a test suite first (to help prevent regressions when working on the bugs)? Thank you, Alex Dowad |

Hello everybody, I decided that the bug fix in egrep.y needed to be spread out more, so I made a new release of cscope today. It's tagged v15_8b in CVS, and the release tar ball is out on SourceForge.net. Hans-Bernhard Broeker |

You can generate a cscope.files using a find command where access time of the files must be bigger than date of last build (date when make was called, not date of last executable). -- Roberto E.

While that may be so, please keep in mind that cscope is a tool for inspecting the source. As in: all of it. It'll index code in non-taken #if/#else blocks, code in functions that aren't ever actually called, etc. And that's actually a good thing, because that way you won't miss stuff that's just disabled at the moment. Finding more than you were looking for may seem to hurt, but it's nowhere near as bad as _not_ finding stuff that you were, indeed, looking for, and never knowing about it. If you don't even see large parts of the source, any idea you form about the source by looking at that subset, and more so any change you make to it, is endangered by tunnel vision. You'll end up checking/changing "all" occurrences of a given name, but missing a good deal of them, because they weren't in your current filtered view. People will be _very_ cross with you if you submit a change that breaks virtually all builds of the kernel except the particular one you were looking at. > If there was a way to limit the search results to only contain hits > for source files that had actually been used for the last build it > would be awesome. So run cscope with a file list that holds only those files. Easy. Building that list is none of cscope's business, though. That would violate the "one tool <--> one task" principle of Unix. To make any sense, this file has to be built by make itself, using the actual Makefiles, and the same configuration options used to build the kernel + modules itself. The kernel Makefile already builds such a cscope.files, but it puts all available C sources in there, not just the active ones. IMHO, that's the correct way of doing it. |

I've been using cscope for years and there's one feature that I think would be awesome. Specifically when using it with the Linux kernel many of the search results aren't relevant to the build that's being worked on. If there was a way to limit the search results to only contain hits for source files that had actually been used for the last build it would be awesome. This could be done by looking for a matching object file in the same directory as the source or, even better, looking at the makefiles to see if the source files was used to generate an existing object file. I did some searching but didn't see any indication that this feature exists. I'd be curious to here what other people think about the idea. Thanks . |

Kbuild is not involved really, these files are just built with plain Makefiles, at least from the symlink side. FWIW ctags seems to cope, that's what I use. But I didn't think of cscope. Given you're the only person who's noticed I suspect most other things haven't broken, fingers crossed :) cheers |

I was made aware that the sorting code I wrote for min-cscope a few years ago (primarily targeted at Windows) was not performing very well on Linux and FreeBSD. I re-wrote the code which now runs faster than GNU sort (at least for the postings list produced by Cscope and compared with the sort version on Ubuntu 12.04). The code is also much more compact and fits nicely within a single source file. Consequently, I would like to propose its inclusion in the main Cscope code. The attached patch provides the new sort.c and sort.h files, the necessary changes to build.c, crossref.c, invlib.c and Makefile.am. It also replaces a linear search within invmake() with a binary search, which gives an additional performance boost. Performance results: Ran a clean Cscope build on the Linux 3.13.7 tree (~35K files) with a warm cache (i.e., ran a clean build first and discarded the results). Vanilla Cscope: elahav@...:~/src/linux-3.13.7$ time /usr/bin/cscope -b -k -q real 0m52.349s user 1m13.193s sys 0m2.680s Modified Cscope: elahav@...:~/src/linux-3.13.7$ time ~/tmp/cscope/src/cscope -b -k -q real 0m33.800s user 0m30.874s sys 0m1.224s Verified that the generated DB is sane by running a query for all references to '.*kernel.*' (there are 7647 of those) and made sure the vanilla and modified versions produced the same results. Note: after applying the patch, you need to run autoreconf to update the various build configuration files. --Elad P.S., There are annoying inconsistencies in indentation throughout the code, with a mixture of tabs and spaces, even within single files. Should probably be cleaned-up at some point. |

The warnings wouldn't even appear if cscope were allowed to do the tree traversal by itself. I.e. cscope -R already skips symlinks silently, without emitting any warnings (see issrcfile() testing for S_ISREG()). You only get those warnings if cscope was explicitly told, by way of a name list file (cscope.index, or -i option), to index a given set of files, and there are symlinks in that list. All you would have to do is keep the symlinks out of that name list file. I don't see a need for a change in cscope here. The desired behaviour can be had without changing cscope. |

I don't recall exactly the reason, but IIRC there was a big discussion long ago about symlinks and our ability to support them (around version 1.94 I think). We decided to not handle symlinks, as they would either point outside our search tree, which we didn't want to include, or would point to another file in the search tree, which made loading them pointless (as we would cover the search in the pointed file).

Gentlemen: The copy of xcscope.el that lives here appears to be stable, so I started a new project with JUST xcscope.el: https://github.com/dkogan/xcscope.el I don't consider this a fork, since the in-tree code doesn't really change. The main changes are listed at that page. This new code is now distributed in MELPA and in Ubuntu and in Debian. As I said before, this tree fixes bugs and adds features, but tries not to break anything or change any functionality that existing users may rely on. I ask that at the very least a note be added to the in-tree xcscope.el to point users to the new tree. If yall agree to do this, I'll reply with the bug tracker and patch tracker entries that have now been handled. Thanks dima |

Hi folks, About 20 years ago, I added some features to cscope, like the progress bar and the concept of using TAB to go back and forth in the interface and a variable number of results shown based on screen size, and a few others (my name is in the README already). I also added the ability to toggle showing the full paths of the files. That last change apparently never got in, so, I've just reimplemented it on top of cscope-15.8a. I have a sourceforge account, but I am unclear about the actual mechanics of how I can get code reviewed and added into the code. Any help you folks could provide would be greatly appreciated.

You're trying to argue against the cold facts there: cscope is one of the oldest Unix programs there is, and it evidently never bothered with VISUAL. Nor does any of the Unix standardization efforts (outside Linux) appear to have included it (not POSIX, not SUS). As-is, cscope already chooses between 4 different programs to run as the viewer/editor: $CSCOPE_EDITOR, $VIEWER, $EDITOR and plain vi. I don't see how adding yet another one makes anything any simpler. Regarding the idea of smuggling a tag letter into the search string: > Uhmmmm, it's true. I usually use cscope for c programs, but it is > possible to use it in other very different ways. I think this funcionality > is great, because there is a lot of information in the cscope index > that can be very usueful to the users, Unfortunately this aspect of the information in the database also appears to be routinely rather out of touch with reality, particularly where the definitions of enum/struct/union are concerned. That doesn't disturb normal operation of cscope, because these are never actually displayed. But exposing this level of detail would tend to cause quite some irritation --- quite possibly more than the feature's worth. cscope is not a replacement for the browsing capabilities of tools 40 years younger than itself like, say, the CDT brower in Eclipse. Nor should it even try to be, IMHO. |

I think this funcionality is great, because there is a lot of information in the cscope index that can be very usueful to the users, and define a new menu option for each of them is no a way. Maybe the solution is looking for a less intrusive way of defining the type of search, or defining a escape character or something like this. Best regards, -- Roberto E.

Hello, I send you some modifications I have done to cscope and I hope can be useful for other users. Patch 0001: Use VISUAL variable when it is avaible and the terminal is not a dumb terminal. I have to add this patch because I usually have to connect to system which terminal interfaces dumb type, so my EDITOR and VISUAL variables have different values, but I usually want see sources with vi and not with ex. Patch 0002: This patch is only a small addition to the manual page, because the assignmenet case was not showed in it. Patch 0003: This patch adds a way of filtering the results in finddef function, since we have information about the kind of symbol. I have add a solution which doesn't increment the number of options in the graphical interface (it is already big), and it is basically add the kind of definition in the search pattern. I don't have modified the manual page, because I don't know if this change will be good for you. I would like listen your opinion about these changes and if they must be modified or something.

Hi Darryl. A diff between the 15.8a release and the latest code is here: http://pub.secretsauce.net/xcscope.el.2013_09_16.patch However I ask that you do not commit it. This patch is large, and is made up of many discrete commits in version control. There is value in preserving the history, so if the changes look good to you, the git repo should be imported rather than squashing it all into a single patch. The history is here for easy review: https://github.com/dkogan/cscope/commits/xcscope_patches[1] If we decide that leaving xcscope.el as part of the larger cscope repository makes sense then I can do the import into CVS. There was a question of coupled releases I asked in an earlier email. Also it would be great to get this code a bit more tested before doing a merge; if you can try it out, that'd be great. As I mentioned to you earlier, I only tested this in emacs 24. What is the oldest version of xemacs you were targeting? How about GNU emacs? I'll test these once I know what they are. Thanks. dima |

Our release cycle has > been very slow these last few year, but it should be possible to > organize a release of cscope once you have done all those xcscope > patches you consider necessary. Hi all. I went through xcscope.el code, and the bugtracker entries. I now have a git tree that merges some of the contributed patches, fixes various bugs and adds some major features I've wanted for a while. Incidentally the biggest feature I've added (handling of multiple searches) was the subject of the larger bugtracker patches. I consider my implementation much better than what was contributed, so those patches were not merged. A changelog is at the bottom of this email. I haven't yet made any comments on the bug tracker itself since the future of my tree isn't decided yet. Now about logistics. I added some features, but there are more I'd like to write when I have some time. If xcscope.el lives in the cscope tree, then any release of xcscope.el is attached to a release of cscope. At least in the near future xcscope.el is going to be a faster-moving project than cscope, so would we be ok with making releases mostly for the sake of xscope.el? Hans-Bernhard and Darryl: I take it you are against splitting this code out of the main cscope tree? I still think this is the best option, but if more frequent releases are possible, then staying joined maybe is ok. I do NOT want to create a fork, so let's try to work something out. The updated xcscope.el tree is at https://github.com/dkogan/cscope/tree/xcscope_patches The feature changelog: - New searches are appended to the *cscope* buffer, instead of overwriting. The user thus sees a history of cscope search results in this buffer, and is able to navigate through all fo them. There is a size limit to keep the buffer from growing out of control. - The *cscope* buffer can be navigated and edited similarly to emacs Diff buffers: - n/p navigates over individual results - k kills individual results - N/P or M-n/M-p navigates over file results - M-k kills file results - M-N/M-P navigates over result sets - M-K kills result sets - Navigation from outside the *cscope* buffer (C-c s n/p/N/P) is restricted to the result set at (point) - Previous searches can be re-run with the 'r' key in the *cscope* buffer. These are written in-place, overwriting the older results. - Fuzzy matching is now enabled/disabled for specific types of searches. This was implemented earlier, but the implementation had a bug and wasn't working - xcscope.el can now work remotely over TRAMP - The cscope-index output now goes to the echo area instead of an explicit new buffer that the user must deal with - Fuzzy searching now works for non-trivial regex searches - The mouse face respects cscope-use-face - Better mouse support: - button3 opens a popup menu that runs prompt-less searches - shift-button3 reruns the last search on the point. This is thus even more prompt-less dima |

Hi,
I'm using version 15.8a on OS X 10.8.4.
Using the curses interface, I'm trying to a text replacement, looking for "free(badptr);" and replacing it with "better_free(goodptr);" [Names have been changed to protect the guilty as sin. ;-) ]
I'm able to search for "free", or "badptr", but I can't get scope to find "free(" or "free\(".
What's the magic here?
Thanks,
Tony

It's good you're around and thank you very much for writing the emacs interface to begin with; I use it all the time. The tracker items in question are in the "bugs" and "patches" trackers: https://sourceforge.net/p/cscope/bugs/ https://sourceforge.net/p/cscope/patches/ As you can see there are quite a few items assigned to "Darryl". I haven't done the work to go through them all, so I can't comment on the quality of the reports. After the maintainership/hosting situation is figured out, I'd like to at least merge the history patch: https://sourceforge.net/p/cscope/patches/65/ and fix its warts (I've been using it for a while; mostly it's good). I'd like to make some UI adjustments. I've seen a patch floating around that moves from one-cscope-process-per-search to one-cscope-process-per-instance. This should help with performance on larger repos. In that same vein, adding support for the interted index would be a good feature. Maybe that should simply be the default. Let me know if you intend to deal with some of the open issues in the tracker. If not, I'm happy to take on both that and further maintenance; ideally outside of sourceforge and CVS. dima |

I'm still here, although I've had no time for anything. If the patches are still in the tracker, point me to them, and I'll take a look and try to merge them. I'll have to again learn how to use sourceforge, though. I think I still have commit permission for the .el files.
