8 4 - How to release lwIP
12 1 Obtaining lwIP from the CVS repository
13 ----------------------------------------
15 To perform an anonymous CVS checkout of the main trunk (this is where
16 bug fixes and incremental enhancements occur), do this:
18 cvs -z3 -d:pserver:anonymous@cvs.sv.gnu.org:/sources/lwip checkout lwip
20 Or, obtain a stable branch (updated with bug fixes only) as follows:
21 cvs -z3 -d:pserver:anonymous@cvs.sv.gnu.org:/sources/lwip checkout \
22 -r STABLE-0_7 -d lwip-0.7 lwip
24 Or, obtain a specific (fixed) release as follows:
25 cvs -z3 -d:pserver:anonymous@cvs.sv.gnu.org:/sources/lwip checkout \
26 -r STABLE-0_7_0 -d lwip-0.7.0 lwip
28 3 Committers/developers CVS access using SSH
29 --------------------------------------------
31 The Savannah server uses SSH (Secure Shell) protocol 2 authentication and encryption.
32 As such, CVS commits to the server occur through a SSH tunnel for project members.
33 To create a SSH2 key pair in UNIX-like environments, do this:
37 Under Windows, a recommended SSH client is "PuTTY", freely available with good
38 documentation and a graphic user interface. Use its key generator.
40 Now paste the id_dsa.pub contents into your Savannah account public key list. Wait
41 a while so that Savannah can update its configuration (This can take minutes).
43 Try to login using SSH:
45 ssh -v your_login@cvs.sv.gnu.org
49 Authenticating with public key "your_key_name"...
50 Server refused to allocate pty
52 then you could login; Savannah refuses to give you a shell - which is OK, as we
53 are allowed to use SSH for CVS only. Now, you should be able to do this:
56 cvs -z3 -d:ext:your_login@cvs.sv.gnu.org:/sources/lwip co lwip
58 after which you can edit your local files with bug fixes or new features and
59 commit them. Make sure you know what you are doing when using CVS to make
60 changes on the repository. If in doubt, ask on the lwip-members mailing list.
62 (If SSH asks about authenticity of the host, you can check the key
63 fingerprint against http://savannah.nongnu.org/cvs/?group=lwip)
66 3 Merging from DEVEL branch to main trunk (stable)
67 --------------------------------------------------
69 Merging is a delicate process in CVS and requires the
70 following disciplined steps in order to prevent conflicts
71 in the future. Conflicts can be hard to solve!
73 Merging from branch A to branch B requires that the A branch
74 has a tag indicating the previous merger. This tag is called
75 'merged_from_A_to_B'. After merging, the tag is moved in the
76 A branch to remember this merger for future merge actions.
78 IMPORTANT: AFTER COMMITTING A SUCCESFUL MERGE IN THE
79 REPOSITORY, THE TAG MUST BE SET ON THE SOURCE BRANCH OF THE
80 MERGE ACTION (REPLACING EXISTING TAGS WITH THE SAME NAME).
82 Merge all changes in DEVEL since our last merge to main:
84 In the working copy of the main trunk:
85 cvs update -P -jmerged_from_DEVEL_to_main -jDEVEL
87 (This will apply the changes between 'merged_from_DEVEL_to_main'
88 and 'DEVEL' to your work set of files)
90 We can now commit the merge result.
91 cvs commit -R -m "Merged from DEVEL to main."
93 If this worked out OK, we now move the tag in the DEVEL branch
94 to this merge point, so we can use this point for future merges:
96 cvs rtag -F -r DEVEL merged_from_DEVEL_to_main lwip
101 First, checkout a clean copy of the branch to be released. Tag this set with
102 tag name "STABLE-0_6_3". (I use release number 0.6.3 throughout this example).
104 Login CVS using pserver authentication, then export a clean copy of the
105 tagged tree. Export is similar to a checkout, except that the CVS metadata
106 is not created locally.
109 cvs -z3 -d:pserver:anonymous@cvs.sv.gnu.org:/sources/lwip checkout \
110 -r STABLE-0_6_3 -d lwip-0.6.3 lwip
112 Archive this directory using tar, gzip'd, bzip2'd and zip'd.
114 tar czvf lwip-0.6.3.tar.gz lwip-0.6.3
115 tar cjvf lwip-0.6.3.tar.bz2 lwip-0.6.3
116 zip -r lwip-0.6.3.zip lwip-0.6.3
118 Now, sign the archives with a detached GPG binary signature as follows:
120 gpg -b lwip-0.6.3.tar.gz
121 gpg -b lwip-0.6.3.tar.bz2
122 gpg -b lwip-0.6.3.zip
124 Upload these files using anonymous FTP:
125 ncftp ftp://savannah.gnu.org/incoming/savannah/lwip
129 Additionally, you may post a news item on Savannah, like this:
131 A new 0.6.3 release is now available here:
132 http://savannah.nongnu.org/files/?group=lwip&highlight=0.6.3
134 You will have to submit this via the user News interface, then approve
135 this via the Administrator News interface.
