In particular, I discuss the main don'ts in VCS. So, - -3 -00:00:06,550 --> 00:00:09,110 -what are some things that you don't want to do, and - -4 -00:00:09,110 --> 00:00:12,687 -you should not do, when you're using a version control system? And - -5 -00:00:12,687 --> 00:00:15,382 -I'm going to mention two, in particular, because these are two - -6 -00:00:15,382 --> 00:00:18,028 -that I witnessed several times when I was teaching this class and - -7 -00:00:18,028 --> 00:00:21,820 -also when collaborating with other people. So, there are two kinds - -8 -00:00:21,820 --> 00:00:25,460 -of resources that you don't want to add to a VCS normally. - -9 -00:00:25,460 --> 00:00:29,070 -One is derived files. For example an executable that is - -10 -00:00:29,070 --> 00:00:31,930 -derived by compiling a set of source files, where the - -11 -00:00:31,930 --> 00:00:34,480 -source files all already in the repository. At that point, - -12 -00:00:34,480 --> 00:00:37,680 -there is no reason to also add the executable file in - -13 -00:00:37,680 --> 00:00:41,150 -the repository. So in general, any executable file should not - -14 -00:00:41,150 --> 00:00:44,570 -be added to repository. The second class of files that I - -15 -00:00:44,570 --> 00:00:47,760 -want to mention is these bulky binary files. If you - -16 -00:00:47,760 --> 00:00:50,600 -have one such file, it is normally not a good idea - -17 -00:00:50,600 --> 00:00:53,430 -to store them under a version control system, to store them - -18 -00:00:53,430 --> 00:00:56,670 -in the repository. There might be exceptions to these rules, but in - -19 -00:00:56,670 --> 00:00:59,070 -general, these are the kind of files that you want to - -20 -00:00:59,070 --> 00:01:02,540 -keep local, and you don't want to put in the VCS repository. - -21 -00:01:02,540 --> 00:01:06,500 -Another typical mistake, and that happens all the time, especially to - -22 -00:01:06,500 --> 00:01:10,650 -novice users of VCS. Is that you get your file from VCS - -23 -00:01:10,650 --> 00:01:13,120 -and so you get your local copy of the file that - -24 -00:01:13,120 --> 00:01:16,270 -was in the VCS, and you want to make some changes, and - -25 -00:01:16,270 --> 00:01:20,090 -before making the changes you decided, no, no let me actually save - -26 -00:01:20,090 --> 00:01:22,410 -a local copy of the file, and I'm going to work on - -27 -00:01:22,410 --> 00:01:24,950 -that one. Or let me save it before I modify it, or - -28 -00:01:24,950 --> 00:01:28,350 -let take a snap shot of a whole tree of files. Just because - -29 -00:01:28,350 --> 00:01:30,830 -I don't really trust the fact that VCS is going to be - -30 -00:01:30,830 --> 00:01:33,170 -able to help and is going to be able to recover from possible - -31 -00:01:33,170 --> 00:01:36,980 -mistakes. Never ever do that. I have seen that done many times, - -32 -00:01:36,980 --> 00:01:41,570 -and it always leads to disasters. First of all it is useless, and - -33 -00:01:41,570 --> 00:01:44,000 -second it's risky. Because then what happens is that at - -34 -00:01:44,000 --> 00:01:46,610 -the time in which you have to turn in your assignment, - -35 -00:01:46,610 --> 00:01:48,330 -in the case you are doing an assignment, but even in - -36 -00:01:48,330 --> 00:01:50,740 -more serious situation, when you have to turn in your code, - -37 -00:01:50,740 --> 00:01:54,620 -for example to your colleagues. You always end up being confused - -38 -00:01:54,620 --> 00:01:59,010 -about which is the version that you're really using. So absolutely - -39 -00:01:59,010 --> 00:02:03,262 -no local copies. No local redundancy when you're using a version - -40 -00:02:03,262 --> 00:02:06,798 -control system. Trust the version control system, and trust the version - -41 -00:02:06,798 --> 00:02:09,280 -control system to be able to manage your versions. You - -42 -00:02:09,280 --> 00:02:13,350 -can always save it, commit it, retrieve previous versions, and you'll - -43 -00:02:13,350 --> 00:02:15,530 -be able to do everything that you can do by copying - -44 -00:02:15,530 --> 00:02:19,240 -the file yourself, and even more. So again, try the VCS. |
