With the 4 header files removed in the previous patch, this commit just changes all those obsolete references to that new consolidated 'misc.h' header file instead. Signed-off-by: Jim Warner <james.warner@comcast.net>

BUG REPORTS
|
|
===========
|
|
|
|
The following is information for reporting bugs. Please read
|
|
the file as well as the documentation for the relevant program
|
|
before posting. This document is more useful for advanced users
|
|
and the people that package for the distributions.
|
|
|
|
Also if you are an end-user of the programs and not the packager
|
|
and are using a distribution, check their bug tracker first,
|
|
you may find its a known bug already.
|
|
|
|
|
|
Where to send
|
|
-------------
|
|
You can raise issues on the GitLab issues tracker which is
|
|
located at https://gitlab.com/procps-ng/procps/issues You
|
|
will need a GitLab login to do so.
|
|
|
|
Alternatively send comments, bug reports, patches, etc.
|
|
to the email list procps@freelists.org
|
|
|
|
What to send
|
|
------------
|
|
It is much more useful to us if a program really crashes to recompile it
|
|
with make `CFLAGS=-ggdb -O`, run it with `gdb prog` and `run` and send
|
|
me a stack trace (`bt` command). That said, any bug report is still
|
|
better than none.
|
|
|
|
strace and ltrace output are very helpful:
|
|
|
|
> strace -o output-file ps --blah
|
|
> bzip2 output-file
|
|
|
|
The output of `ps --info` is often quite useful, even if the problem
|
|
is not with ps itself. A lot of the utilities use the same library.
|
|
|
|
Merge Requests
|
|
--------------
|
|
Merge requests are fine to use and give a central place for
|
|
everyone involved to have a look. Merge requests are found
|
|
on GitLab at https://gitlab.com/procps-ng/procps/merge_requests
|
|
It is best to follow up your merge request with an email to
|
|
the list saying what you have done.
|
|
|
|
Patches
|
|
-------
|
|
While merge requests are preferred, patches are also welcome.
|
|
Get latest version of the source from upstream git.
|
|
|
|
> git clone git@gitlab.com:procps-ng/procps.git
|
|
|
|
and use `git format-patch` format. It is fine to attach patches as
|
|
compressed tar balls. When you are about to send very large number
|
|
of patches consider setting up your personal clone, and send a pull
|
|
request.
|
|
|
|
> git request-pull commit-id \
|
|
> git://gitorious.org/~yourlogin/procps/your-clone.git
|
|
|

|
Kernel-Dependent Patches
|
|
------------------------
|
|
If you send patches which are specific to *running* with a particular
|
|
kernel version of /proc, please condition them with the runtime determined
|
|
variable `linux_version_code` from libproc/version.c. It is the same
|
|
number as the macro `LINUX_VERSION_CODE` for which the kernel /proc fs
|
|
code was compiled.
|
|
|
|
A macro is provide in libproc/misc.h to construct the code from its
|
|
components, e.g.
|
|
> if (linux_version_code < LINUX_VERSION(2,5,41))
|
|
> /* blah blah blah */
|
|
A startup call to `set_linux_version` may also be necessary.
|
|
|
|
Of course, if a bug is due to a change in kernel file formats, it would
|
|
be best to first try to generalize the parsing, since the code is then
|
|
more resilient against future change.
|
|
|
|
Code Structure
|
|
--------------
|
|
A goal is to encapsulate *all* parsing dependent on /proc
|
|
file formats into the libproc library. If the API is general enough
|
|
it can hopefully stabilize and then /proc changes might only require
|
|
updating libproc.so. Beyond that having the set of utilities be simple
|
|
command lines parsers and output formatters and encapsulating all kernel
|
|
divergence in libproc is the way to go.
|
|
|
|
Hence if you are submitting a new program or are fixing an old one, keep
|
|
in mind that adding files to libproc which encapsulate such things is
|
|
more desirable than patching the actual driver program. (well, except
|
|
to move it toward the API of the library).
