Not at all, though the newer versions (*.sln/vcproj) are. They are vaguely similar to a makefile, though you certainly ought to be more careful editing them since they have to be parsed back in (unlike a makefile).

Ho hum. No, those files are fine. The files that Pete marked CRLF in his gitattributes are the ones that actually "go weird". And I do need to touch them, though the problem arises even if I don't.

If you didn't apply [1], which also converted all the project files in the repo then, yes, as I tried to point out, your files would still be LF'd in the repo (while mine are CRLF'd). Another possibility is that git is not smart enough to detect that if a .gitattributes is part of a commit, it should create it first and apply its settings (and I guess I should have broken my commit there, as I did break it up for official), so even as the patch operation should have converted the files in your repo, it didn't, and you would have had to unix2dos them right after.

(But yes, as mentioned elsewhere, notepad and > windiff are my primary reasons.) Do we really care about Notepad? As for Windiff, I am not sure. But there are tools which works with LF line endings. Actually I do not understand why we have such a long thread, as Orin and others have pointed out the LF works for the VStudio. And then binmode is recommended by Cygwin as pointed by Segher. So why not make everything LF and do not allow MSysGit to act smart and convert anything. In that case, everything would be fine. I think this is the easiest and pragmatic solution. I use Cygwin git and never have any issues with various git repositories, some of them cross-platform. I usually use Notepad++ to view text file under Windows. -- Xiaofan |

It would seem I'm repeating myself multiple times in this thread, but having to do so here is a bit absurd, given that you quoted the answer to your own question: yes.

Neither did Pete, I'm sure. We respond until we either agree or get tired of arguing. So...I'm not sure I understand why it matters. Ignore it if you're not interested in the outcome. Believe it or not, you missed a few off-list responses on certain tangents. If all you look at is the length, then sure, it's all going to be statistics. But if you read the thread's content, then it should hopefully make sense. Regards, Michael |

It hasn't been the case when I've accidentally used more in a Linux shell window - flashing text if I'm lucky - invisible text if I'm not! As for the .ds?, .vcproj and .sln files, these are _opaque_ files that you shouldn't be poking around in. Sure, we happen to know that some are text with <CR><LF> line endings. IMO, whatever the OS, this SHOULD NOT be changed. You SHOULD NOT be editing them with a tool that does not preserve the <CR><LF>. They should be treated as binary files, but since we know they are text with <CR><LF> line endings, I don't see a problem with treating them as text files that always have <CR><LF> line endings _as an optimization_. As I recall, the problem I had was that git gave me files with <LF> line endings, Visual Studio didn't care, but wrote out lines with <CR><LF> endings and then Peter complained when a patch had some <CR>s in it. BTW, I'm not a fan of <CR><LF> line endings, so please don't interpret the above as such. Orin. |

There are lots of big advantages to having small, independent patches for independent problems / improvements. I agree it doesn't make much sense to spend lots of time on pulling apart bigger patches; but if you can make them as small commits _in the first place_, it is _less work in total_ even. And, in this case, I know for a fact that some of those were created as these three-liners (I suggested one of-em, the quoting thing -- newer autoconf complains without it). Segher |

Pete, please send also config.h along with config.log. Since libusbi.h has a #include <config.h> at the top (as it should) it seems that the configure test failed to detect lack of nfds_t on cygwin, although it worked on the older OS X. :\ //Peter |

I thought the problem was with the configure check, but thinking a little further about this I actually don't need those files because in fact the configure test is working correctly - just that Cygwin should be an exception. > I did check that nfds_t was properly detected from configure, that > the config.h defined it properly as a result, that it was included > in linusbi.h and concluded that the piece that's missing is a > #include <poll.h> in poll_posix.h. No. Cygwin is making things a bit complicated for us, because it provides a poll() which I believe we don't want to use. Right? I was thinking that nfds_t was being incorrectly detected, but it is of course available in Cygwin, and libusbi.h doesn't pull in the header that defines it. While that happens to be correct on Windows it is actually a bug which should also be fixed. I think it belongs in the same commit. > Now, properly including poll.h without breaking things is going to > require some time, Actually autoconf makes it trivial. But I don't think this is the problem for Cygwin. Do we want to use Cygwin's poll()? I think not - I'm not sure if it will do what we want, or perform as well as poll_windows. I would be happy with poll_windows also for Cygwin. What do you say? //Peter |

I've changed the commit a bit, and my current tree is now in the libusb-stuge.git branch called testing. I've reset my master back to the libusb.git state and will move on to clean up Trac later, maybe not until next week. Please grab the testing branch, I hope it'll fix this problem.

Also, if you're adding .gitattributes [1], can you please add "*.sh eol=lf" in it (or at least autogen.sh).

Finally, it looks like if you have both the .gitattributes and configure.ac changes in the same commit, you still get CRLFs, because obviously the .gitattributes does not apply to this pull yet. To be safe, (and I can't believe I'm advocating this), this commit should be broken down. Regards, /Pete |

They are distinct changes, and they were not all split after the fact.

Again, distinct changes, they may or may not be applied. git is quite able to deal with many commits, and high commit resolution allows us to get the most out of git. > IMO, a simple "configure.ac improvements" with bullet points detailing > each improvements could do wonders, especially as configure.ac is far > from being our bread and butter. Actually here the distinct commits help a lot, specifically *because* we're still learning about configure.ac. It makes each step clear for reviewers. You may already have noticed that several of the commits touch the same code, and quite a lot of information about the way from point A in the code to point B would have been lost if everything was jammed into a single commit. Very difficult to review, and I think not acceptable at least for anything in libusb core. As for backend-specific changes I will try to follow Daniel's lead and go with whatever patches are sent. > If producing such commits has been taking time away from > progressing on the actual official integration for 1.0.9, > maybe we need to review our approach... It is very much a part of the work to prepare the next release. The many commits is how I work, and also how I expect others to work; because it allows us to take full advantage of git, and because it is logical, which makes it easy for others to follow. One change = one commit. I rebased quite frequently making those changes, because I didn't have a plan and was learning along the way, and because I discovered more and more things to fix. This is why I like personal repos - they're a sandbox, but still allow easy review so that the sandcastle can be made even greater. :) //Peter |

In that case, maybe things would work better for you. Please understand that we are not trying to address a problem that only affects me here, even if I'm the only one to have reported it so far. We are trying to address a problem that *will* potentially affect all TGit/msys-git users even if they switch to different gits afterwards, including Linux. As far as my testings are concerned, any user of Tgit/msys-git using default settings should be affected, and that's not something we can fix upstream. Even if you later switch to using cygwin or even Linux git on the directory you cloned with Tgit/msys-git, you will get issues [1], so basically that means either not using Tgit/msys-git or making sure that you change your default options before you even attempt to clone a directory. If someone is new to git (yes, you can be both new to git AND want to participate in libusb internal development), they're unlikely to be aware of the problem. Sure, we could point the issue out on our website, but that's just a selfish approach IMO - see the end of my e-mail. Even if I was the only person affected, "don't use tool X, use tool Y instead" seems like poor advice when we know exactly how to fix the issue for tool X, especially when it's a 10 secs fix. When something's difficult to fix with tool X, advocating switching to tool Y may be good advice. That is not the case here. And I'm really starting to wonder how committed we are to our users when it looks like, there again, we are reluctant about introducing *simple* 30 seconds fixes in our tree, and instead foster the "upgrade your tools / don't use tool X" approach. We know exactly how to avoid the issue, and it's trivial to fix, so let's help our users instead of placing yet another set of demands on them dammit! But let me elaborate a little bit on where I come from here. Unless you are omniscient and know for certain that this fix will introduce problems that will result in more time spent by the libusb developers to fix them than the collective amount of time that is going to be wasted by libusb users having to switch/upgrade/fix their tools, then you should go for the fix, because the expectation is that, for what looks to me as a very selfish reason (spare some of *your* time by placing an unneeded burden on others), you are likely to deprive your users of the very same valuable resource, and more damagingly, to a greater collective amount, especially if you aim your project at becoming a de-facto standard of accessing USB devices on all the major platforms. That's the precise reason I pushed so hard for the CJK libtool fix, that's the reason I will push again to have xusb and MSVC projects included, regardless of what the maintainers want, as the equation is very simple: If you know that implementing something will take some or potentially a lot of your development time, but you suspect that not doing it will force your users to collectively waste a larger amount of time, then it becomes *criminal* not to do it when you have the capacity to do so. Not providing xusb (which we have the capacity for - it's already there) = time wasted for users who want something with more meat than lsusb. Not having MS project files (same) = time wasted for MS users that have either to recreate or download them for a separate source, etc. That's how libusb should work IMO and also why, for instance, we should also be fast-tracking things like hotplug (capacity wise, it's pretty much already there too!), because there is actual demand for it, and, unlike what is the case for libusb-win32, there doesn't exist an alternative, which results in time wasted (working around or doing their own implementation) by our users.
