17 <h2>SliTaz Cook & Cooker</h2>
19 <p>
20 The SliTaz Cookutils provide tools and utils to help build SliTaz packages. They
21 are easy to use and learn, fast and light. You will be able to create SliTaz
22 packages in a few commands. The cookutils provide the 'cook' utility and the
23 <a href="#cooker">Cooker</a>.
24 </p>
25 <p>
26 Cook lets you compile and create a package, provide a log file and check the
27 receipt/package quality. The Cooker is a build bot with more automation
28 and can be used as a frontend to cook, since it provides a CGI/web interface
29 which lets you view cook logs in a nice and colored way. Cook and the Cooker
30 use the same DB files and wok, they share <a href="#blocked">blocked</a>
31 and broken packages as well as any activity.
32 </p>
34 <h3>Cook usage</h3>
35 <p>
36 Cook provides a small built-in help usage that you can display with the
37 command 'usage'. It also has some options to perform special tasks on
38 a package before cooking it or after. To get help and usage:
39 </p>
40 <pre>
41 # cook usage
42 </pre>
44 <h3>Howto</h3>
45 <p>
46 The first thing you will have to do before building packages is setup
47 your environment. The 2 recommended ways of working: cook directly on host
48 or cook in chroot to protect your host. In the case you want to work in a
49 chroot you can install and use Tazdev to create one and chroot into it:
50 </p>
51 <pre>
52 # tazdev gen-chroot && tazdev chroot
53 </pre>
54 <p>
55 By default Tazdev creates a chroot in /home/slitaz/cooking/chroot but you
56 can specify a custom path in the argument. The chroot location is not
57 important, when you will be in the chroot you will use standard SliTaz
58 paths such as /home/slitaz/wok for the wok directory or /home/slitaz/log
59 for all the cook logs. As usual you can diplay tazdev help usage with:
60 tazdev usage.
61 </p>
62 <p>
63 When you use a chroot there are 2 special directories mounted with the bind
64 option: src and packages. The sources for all packages are stored by default
65 in /home/slitaz/src, this directory is mounted into the chroot so the utils
66 can use them. This method lets you share sources between many chroots such
67 as one for cooking and one for stable. The packages directory default
68 location is: /home/slitaz/[version]/packages so they are not in the chroot
69 and are safe in case the chroot is removed by error.
70 </p>
72 <h3>Getting started</h3>
73 <p>
74 So you have decided the way you want to work, so lets prepare the cook environment.
75 Cook uses the cook.conf configuration file, if you want to use custom paths for
76 SliTaz directories and files, you'll have to modify it. The setup will create
77 some directories and files to keep trace of activity and errors, all files
78 are pure plain text files that you can open in a text editor. To prepare
79 your environment:
80 </p>
81 <pre>
82 # cook setup
83 </pre>
84 <p>
85 The setup command has a --wok option which lets you clone a SliTaz wok while
86 setting up your cook environment. Even if you not yet an official developer
87 you can clone it and use existing packages as an example to create your own.
88 To setup and clone the wok:
89 </p>
90 <pre>
91 # cook setup --wok
92 </pre>
94 <h3>Test your environment</h3>
95 <p>
96 Cook provides a test command which will create a package and cook it. This lets
97 you see if your enviroment is working and it provides an example package with
98 a receipt. The dummy package is named 'cooktest' and can be removed after
99 testing. To cook the cooktest:
100 </p>
101 <pre>
102 # cook test
103 </pre>
105 <h3>Create and cook</h3>
106 <p>
107 If you environment is setup corectly you can start creating and compiling
108 SliTaz packages from your wok. To create a new package with an empty receipt:
109 </p>
110 <pre>
111 # cook new pkgname
112 </pre>
113 <p>
114 If you have just created a new package, you'll have to edit the receipt with your
115 favorite text editor. When the receipt is ready or if you have existing
116 packages, you can cook it:
117 </p>
118 <pre>
119 # cook pkgname
120 </pre>
121 <p>
122 If all went well you will find your packages in the $SLITAZ/packages
123 directory and any produced files in $SLITAZ/wok/pkgname.
124 </p>
126 <h3>Cook and install</h3>
127 <p>
128 If you want to cook and install the package in one command:
129 </p>
130 <pre>
131 # cook pkgname --install
132 </pre>
134 <h3>Get sources</h3>
135 <p>
136 If you want or need to download only the source of a package without
137 building it, you can use the option --getsrc as below:
138 </p>
139 <pre>
140 # cook pkgname --getsrc
141 </pre>
143 <h3>Clean packages</h3>
144 <p>
145 After compilation and packaging there are several files in the wok that take up
146 disk space. To clean a single package:
147 </p>
148 <pre>
149 # cook pkgname --clean
150 </pre>
151 <p>
152 You can also clean the full wok at once or you can choose to keep SliTaz
153 related files and just remove the source:
154 </p>
155 <pre>
156 # cook clean-wok
157 # cook clean-src
158 </pre>
160 <h3>Packages list</h3>
161 <p>
162 Cook can list packages in the wok and also create a suitable packages list
163 for Tazpkg. This lets you create a locale packages repository quite easily
164 and is used to create the official SliTaz packages list found on the mirrors.
165 To list the current wok used by cook (you don't need to be root):
166 </p>
167 <pre>
168 $ cook list-wok
169 </pre>
170 <p>
171 To create a packages list:
172 </p>
173 <pre>
174 # cook pkglist
175 </pre>
177 <a name="cooker"></a>
178 <h3>The Cooker</h3>
179 <p>
180 The Cooker is a Build Bot, its first function is to check for commits in a wok,
181 create an ordered cooklist and cook all modified packages. It can also be
182 used as a frontend to cook since they both use the same files. The Cooker can
183 also be used to cook a big list of packages at once such as all the packages
184 in a flavor. The Cooker provides a nice CGI/Web interface that works by
185 default on any SliTaz system since it provides CGI support via the Busybox httpd
186 web server.
187 </p>
188 <p>
189 The Cooker provides a small built-in help usage and short command switch.
190 For example to display usage you can use:
191 </p>
192 <pre>
193 # cooker usage
194 # cooker -u
195 </pre>
197 <h3>Cooker setup</h3>
198 <p>
199 Like cook, the Cooker needs a working environment before starting to use it.
200 The main difference with the cook environment is that the Cooker needs 2 woks.
201 One Hg and clean wok as a reference and one build wok. In this way it is easy
202 to compare both woks and get modifications. If you already have a cook
203 environment, you must move your wok before setting up the Cooker or it
204 will complain. Setup will also install a set of development packages that
205 can be configured in the cook.conf configuration file and the variable
206 SETUP_PKGS. To setup your cooker environment:
207 </p>
208 <pre>
209 # cooker setup
210 </pre>
211 <p>
212 If all went well you have now 2 woks, base developement packages installed
213 and all needed files created. The default behavior is to check for commits,
214 you can run a test:
215 </p>
216 <pre>
217 # cooker
218 </pre>
220 <h3>Cooker cook</h3>
221 <p>
222 Again, 2 ways to work now: make changes in the clean Hg wok and launch the
223 cooker without any arguments or cook packages manually. The cooker lets you
224 cook a single package or all packages of a category or a flavor. You can also
225 try to build all unbuilt packages, but be aware the Cooker was not designed
226 to handle thousand of packages.
227 </p>
228 <p>
229 To cook a single package which is the same as 'cook pkgname' but with more
230 logs:
231 </p>
232 <pre>
233 # cooker pkg pkgname
234 </pre>
235 <p>
236 To cook more than one package at once you have different kind of choices.
237 You can use an existing package such as used for Live flavors, you can also
238 use a custom list using the package names listed line by line. Finally you can
239 build all packages of a category.
240 </p>
241 <pre>
242 # cooker flavor [name]
243 # cooker list [/path/to/cooklist]
244 # cooker cat [category]
245 </pre>
247 <a name="blocked"></a>
248 <h3>Blocked packages</h3>
249 <p>
250 Cook and the Cooker handle a file with a list of blocked package so they will
251 not cook when commits happen or if a cooklist is used. This is very useful
252 for a Cooker Build Bot in production. When you block or unblock a package
253 you can add a note to the cooknotes. Blocking packages example:
254 </p>
255 <pre>
256 # cook pkgname --block
257 # cooker block pkgname
258 # cooker -n "Blocked pkgname note"
259 </pre>
260 <p>
261 The list of blocked packages are also displayed on the Cooker web interface.
262 To unblock a package you have to use the unblock command or cook --unblock
263 option:
264 </p>
265 <pre>
266 # cook pkgname --unblock
267 # cooker unblock pkgname
268 </pre>
270 <h3>Cooker CGI/Web</h3>
271 <p>
272 To let you view log files in a nice way, keep trace of activity and help find
273 errors, you can use the Cooker Web interface located by default in the folder
274 /var/www/cgi-bin/cooker. If you don't use a chroot and the Busybox httpd
275 web server is running, the web interface will work without configuration and
276 should be reachable at: <a href="http://localhost/cgi-bin/cooker/cooker.cgi">
277 http://localhost/cgi-bin/cooker/cooker.cgi</a>
278 </p>
279 <p>
280 If you used a chroot environment, you should also install cookutils on your
281 host and modify the SLITAZ path variable. A standard working way is to have
282 a chroot in:
283 </p>
284 <pre>
285 /home/slitaz/cooking/chroot
286 </pre>
287 <p>
288 With /etc/slitaz/cook.conf modified as below:
289 </p>
290 <pre>
291 SLITAZ="/home/slitaz/cooking/chroot/home/slitaz"
292 </pre>
293 <p>
294 Note: It's not obligatory to install the cookutils on your host to use the
295 web interface, you can also copy the cooker.cgi and style.css files for
296 example in your ~/Public directory and use a custom cook.conf with it. The
297 advantage of installing cookutils on the host is to get regular updates via
298 the Tazpkg packages manager. Say you have cloned or downloaded the cookutils:
299 </p>
300 <pre>
301 $ cp -a cookutils/web ~/Public/cgi-bin/cooker
302 $ cp -f cookutils/cook.conf ~/Public/cgi-bin/cooker
303 </pre>
304 <p>
305 Edit the configuration file: ~/Public/cgi-bin/cooker/cook.conf to set your
306 SLITAZ path and you're all done!
307 </p>
309 <h3>Cooknotes</h3>
310 <p>
311 The cooknotes feature lets you write small personal notes about packaging
312 and is useful for collaboration. The cooknotes was coded to let the SliTaz
313 Cooker bot maintainers share notes between themselves and other contributors.
314 The Cooker can block a package's build or recook packages manually, for example
315 it's nice to make a note if a package is blocked so that the maintainer knows why
316 admin did that. Cooknotes are displayed on the web interface and can be
317 checked from a cmdline:
318 </p>
319 <pre>
320 # cooker note "Blocked pkgname due to heavy CPU load"
321 # cooker notes
322 </pre>
324 <h3>Cooker as a Build Bot</h3>
325 <p>
326 The Cooker is designed to be a Built Bot for SliTaz, this means it monitors
327 2 woks, updates the Hg wok, gets the differences and cooks all packages that
328 have been committed. To run The Cooker automatically you must use cron and add a
329 single line to root crontabs in /var/spool/cron/crontabs. Say you would like
330 to run the Cooker every 2 hours:
331 </p>
