+Patch Life Cycle
+================
+
+[[!toc startlevel=2]]
+
+
+* * *
+
+
+Start
+-----
+
+Follow the steps listed on the [[package porting page|porting_guide_for_dummies]].
+
+
+Discuss
+-------
+
+Send the patch for review to [debian-hurd@lists.debian.org](mailto:debian-hurd@lists.debian.org).
+**Before** sending the patch, make sure that you've solved all the known problems listed in the [[package porting general introduction|hurd/porting/guidelines]]
+and the [[porting guide for dummies|porting_guide_for_dummies]].
+
+
+Submit Draft
+------------
+
+When the patch is good enough, you can write the draft of the official bug report.
+This draft should first be sent for review to [debian-hurd@lists.debian.org](mailto:debian-hurd@lists.debian.org) with the patch attached.
+
+Here is an example for memstat:
+
+ Source: memstat
+ Version: 0.9
+ Severity: important
+ Tags: patch
+ User: debian-hurd@lists.debian.org
+ Usertags: hurd
+ X-DebBugs-CC: debian-hurd@lists.debian.org
+
+ Hi,
+
+ This patch solves the build problems for GNU/Hurd due to PATH_MAX
+ issues. The solution is to make dynamic string allocations instead of
+ using fixed length buffers. The patch involves one file, and is
+ trivial.
+
+ FIXME:
+ Is it really useful to check if BUFSIZ is defined?
+
+ TODO:
+ Should the "whole package" be tested with valgrind on GNU/Linux?!
+ If yes, is there a standard procedure to do it?!
+
+ Thanks!
+ Special thanks to Jérémie and Richard for their comments!
+
+ (Not submitted yet, comments are welcome.)
+
+Once it's been approved, you can proceed to the submission.
+
+
+Submit
+------
+
+The bug report is the same as above, with all the **FIXME**, **TODO** and final comment removed.
+Attach the patch and send it to [submit@debian.org](mailto:submit@debian.org).
+Convention for the attachment name is: `fix_FTBFS4Hurd.patch`
+
+
+Accept
+------
+
+Once the patch has been accepted, update your patch page!
+**Congratulations!**
+

+Porting Guide for Dummies
+=========================
+
+The problems addressed here were encountered while working
+on fixing **PATH_MAX** and **MAXPATHLEN**.
+
+[[!toc startlevel=2 levels=3]]
+
+
+* * *
+
+
+Test on Hurd
+------------
+
+
+### Installing the required files
+
+As `apt-get source` will download and extract many files, you may want to create a dedicated folder for the package and work from there.
+
+ mkdir PACKAGE
+ cd PACKAGE
+ sudo apt-get build-dep PACKAGE
+ apt-get source PACKAGE
+
+
+### Trying to build the package
+
+ cd PACKAGE_SOURCE
+ dpkg-buildpackage -us -uc -rfakeroot -tc
+
+
+### Test a quick fix
+
+In all the files that use **PATH_MAX**, include those lines at the beginning.
+
+ #ifndef PATH_MAX
+ #define PATH_MAX 4196
+ #endif
+
+Try to rebuild the package and see if it's solved the problem.
+If yes, you can start working on the package.
+
+
+* * *
+
+
+Basic things
+------------
+
+### Maintaining a original version
+
+ mkdir old
+ cp -r PACKAGE_SOURCE old/
+
+
+### Coding style
+
+Follow the conventions used in the source code!
+
+ if (condition) {
+ do_smthg();
+ }
+
+is not the same as:
+
+ if (condition)
+ {
+ do_smthg();
+ }
+
+and is not the same as:
+
+ if (condition)
+ do_smthg();
+
+Pay attention to spaces surrounding, or not, arithmetic signs and symbols:
+
+ a = do_smthg( b + c );
+ a = do_smthg(b+c);
+
+
+### Indentation
+
+By default use 8 spaces as the size for 1 tab.
+Then figure out if the code uses tab + 1/2 tab:
+
+ ....if (condition) {
+ ------->do_smthg();
+ ....}
+
+or tab only:
+
+ ------->if (condition) {
+ ------->------->do_smthg();
+ ------->}
+
+
+### Creating a patch
+
+ diff -Naur old/PACKAGE-VERSION PACKAGE-VERSION > fix_FTBFS4Hurd.patch
+
+
+* * *
+
+
+Known problems
+--------------
+
+### Dynamically allocated buffer returned by a function
+
+Use a static buffer
+
+### Buffer used to format an expression containing an INTEGER
+
+The length of an INTEGER in a string can be up to sizeof (int) * 3 + 1.
+
+> The usual trick for "%d" is to use the constant 'sizeof (int) * 3 + 1'.
+I included + 1 for the sign, but it's not really necessary
+if we exepect sizeof(int) >= 2, which we probably should.
+**Jérémie Koenig**
+
+ log(MAX_INT)
+ = log(2 ^ 32)
+ = 32 * log(2)
+ = 4 * 8 * log(2)
+ = sizeof(int) * 2.40823997
+ < sizeof(int) * 3
+
+
+### Proper use of realloc()
+
+use a new_buff to check if everything went fine Free buf if realloc failed (and prog doesn't exit)
+
+
+### Reading lines from file
+
+Function to read line (no size limit, ending with "\n") from a file.
+
+ +static char *get_line(FILE *f)
+ +{
+ + char *buff = NULL;
+ + char *new_buff = NULL;
+ + size_t buff_size = 0;
+ + size_t last = 0;
+ +
+ + while (!feof(f)) {
+ + buff_size = buff_size ? buff_size * 2 : BUFSIZ;
+ + new_buff = realloc(buff, buff_size);
+ + if (new_buff == NULL) {
+ + free(buff);
+ + return NULL;
+ + }
+ + buff = new_buff;
+ + if (fgets(buff + last, buff_size - last, f) == NULL) {
+ + free(buff);
+ + return NULL;
+ + }
+ + last = strlen(buff);
+ + if (buff[last - 1] == '\n')
+ + return buff;
+ + }
+ + return buff;
+ +}
+
+
+### Proper use of readlink()
+
+One has to rely on lstat() to get the size of the link that readlink() returns.
+
+Declare what you need:
+
+ char *linkname = NULL;
+ struct stat sb;
+ ssize_t len = -1;
+
+Call lstat() and check return value:
+
+ if (lstat(filename, &sb) == -1) {
+
+Create a buffer of the appropriate size and check the return value:
+
+ linkname = malloc(sb.st_size + 1);
+ if (linkname == NULL) {
+
+Call readlink(), check return value and set the null char in the linkname:
+
+ len = readlink(filename, linkname, sb.st_size + 1);
+ if (len < 0 || len > sb.st_size) {
+ ...
+ linkname[sb.st_size] = '\0';

+The code uses `linux/types.h`, that has to be replaced by `sys/types.h`, but also uses `linux/random.h` which has no equivalent I know of.
