The old code only supports a file whose size is less then or equal
to INT_MAX (due to a reasonable(!) limit in M2Crypto). The actual
issue is in core.http_request which mmap(...)s the file, wraps it
into a memoryview/buffer and then passes the memoryview/buffer to
urlopen. Eventually, the whole memoryview/buffer is read into memory
(see m2_PyObject_GetBufferInt). If the file is too large (> INT_MAX),
m2_PyObject_GetBufferInt raises a ValueError (which is perfectly
fine!).
Reading a whole file into memory is completely insane. In order to
avoid this, we now simply pass a file-like object to urlopen (more
precisely, the file-like object is associated with the Request
instance that is passed to urlopen). The advantange is that the
file-like object is processed in chunks of 8192 bytes (see
http.client.HTTPConnection) (that is, only 8192 bytes are read into
memory (instead of the whole file)).
There are two pitfalls when passing a file-like object to urlopen:
* By default, a chunked Transfer-Encoding is applied. It seems that
some servers (like api.o.o) do not like this (PUTing a file with
a chunked Transfer-Encoding to api.o.o results in status 400). In
order to avoid a chunked Transfer-Encoding, we explicitly set a
Content-Length header (we also do this in the non-file case (just
for the sake of completeness)).
* If the request fails with status 401, it is retried with an
appropriate Authorization header. When retrying the request, the
file's offset has to be repositioned to the beginning of the file
(otherwise, a 0-length body is sent which most likely does not
match the Content-Length header).
Note: core.http_request's "data" and "file" parameters are now mutually
exclusive because specifying both makes no sense (only one of them
is considered) and it simplifies the implementation a bit.
Fixes: #202 ("osc user authentification seems to be broken with last
commit")
Fixes: #304 ("osc ci - cannot handle more than 2 GB file uploads")
This kind of guessing can not really work here and leads to failing
builds when using KVM. (eg. when using a preinstallimage)
Removing the code, since we have a now a way to allow the user to
specify building as user via su-wrapper config
If osc is invoked, for instance, via "osc -d rbl ... > log.txt 2>&1",
writes to stderr and stdout do not necessarily appear in program order
in the log.txt file. More precisely, it is possible that the buildlog
comes first and the http debug output is at the end of the
file.
During osc/python3 startup (with the redirection from above), the
following is done:
- make stdout line buffered (due to the code in osc-wrapper.py)
- make stderr buffered (but not line buffered) because stderr does
not refer to a tty (python3 startup)
Consequently, if osc has code like
print("foo")
print("bar", file=sys.stderr)
print("baz")
it is possible that the contents of the log.txt is
foo
baz
bar
because stderr is buffered (but not line buffered). In order to fix
this, make stderr line buffered, too.
Element.getchildren is deprecated and not available on python39
anymore. Instead, iterate over the element itself (which iterates
over the element's children).
Fixes: #903 ("AttributeError: 'xml.etree.ElementTree.Element' object
has no attribute 'getchildren'")
Most osc commands support slash notation for the specification of
a project package pair. That is, "osc <cmd> prj/pkg" has the same
semantics as "osc <cmd> prj pkg" (in most cases).
For consistency reasons, "osc creq" should also support the slash
notation for the action type's arguments. That is, for instance,
"osc creq -a submit src_prj/src_pkg dst_prj/dst_pkg" should have the
same effect as "osc creq -a submit src_prj src_pkg dst_prj dst_pkg".

Add --lastsucceeded/--last-succeeded option to "osc buildlog" (the latter
option is also added to "osc remotebuildlog").
Also take the --lastsucceeded option into account when computing the
file offset (for the corresponding *tail commands).
Moreover, improve the error message in case of an unknown build type (now,
it also includes flatpak* filenames).
Workaround/fix for pypi deployment via travis.
Note: I cannot really "review" this change because I have no clue about
travis. Since the current pypi deployment via travis does not seem to
work, merging it does not seem to be a problem.
Probably fixes: #884 ("osc pypi artifact is not up to date")
Deployment via Travis CI failed due an error during
cleanup (#884):
`Could not restore untracked files from stash entry`
Disabling the cleanup fixes this problem.
If there are existing requests that should be superseded, the old
code stores the Request instances in the myreqs list, which is
returned to the caller. However, the caller expects only request
ids instead of instances of class Request. Eventually, this results
in a type error - excerpt:
...
File "/usr/lib/python3.8/site-packages/osc/commandline.py", line 1892, in do_createrequest
change_request_state(apiurl, srid, 'superseded',
File "/usr/lib/python3.8/site-packages/osc/core.py", line 4322, in change_request_state
u = makeurl(apiurl,
File "/usr/lib/python3.8/site-packages/osc/core.py", line 3326, in makeurl
return urlunsplit((scheme, netloc, '/'.join([path] + list(l)), query, ''))
TypeError: sequence item 2: expected str instance, Request found
Hence, simply return the request ids instead of the Request instances.
Note: this changes the API of the Osc._submit_request method but
this is OK because it is not part of the public API.
When calling "osc creq -a prj1 foo prj2 bar -a submit prj1 bar prj2 bar",
the requests that could be superseded are calculated two times for the
prj2/bar package. Hence, they could end up two times in the "supersede"
list (see do_createrequest) In order to avoid duplicates, use a set
instead of a list.
Kudos to darix for pointing this out!
Note: it is a bit questionable if osc's current semantics makes sense
in the above example.
When creating a new request via the core.Request.create method, there is
no need to escape the data that is assigned to the "description" attribute
of a core.Request instance. Internally, core.Request.create ensures that
the data, which is POSTed to the api, is correctly escaped (the escaping
is implicitly done by ET (see core.Request.to_str)). Manually escaping the
description results in a double escaping (the escaped description is
escaped by ET again) - this is not the desired behavior.
Analogously, there is no need to escape the data that is passed to the
message parameter of the core.create_submit_request function because
core.create_submit_request takes care of escaping it.

Using os.getcwd() in combination with a subsequent .encode() is error
prone:
marcus@linux:~> mkdir illegal_utf-8_encoding_$'\xff'_dir
marcus@linux:~> cd illegal_utf-8_encoding_$'\xff'_dir/
marcus@linux:~/illegal_utf-8_encoding_ÿ_dir> python3
Python 3.8.6 (default, Nov 09 2020, 12:09:06) [GCC] on linux

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'utf-8' codec can't encode character '\udcff' in position 36: surrogates not allowed

Hence, use os.getcwdb(), which returns a bytes, instead of
os.getcwd().encode().
Fixes: commit 36f7b8ffe9 ("Fix a
potential TypeError in CpioRead.copyin and CpioRead.copyin_file")
If no dir is passed to util.ArFile.saveTo, dir is set to os.getcwd(),
which returns a str. Since self.name is a bytes, the subsequent
os.path.join(dir, self.name) results in a TypeError.
To fix this, use os.getcwdb(), which returns a bytes instead of a
str.
Support "osc build --vm-type=nspawn". Without this change build_root
is changed to "build_root/.mount", which results in an invalid name
for systemd-nspawn (see build-vm-nspawn in the obs-build codebase).
Now, --vm-type=nspawn behaves the same as --vm-type=lxc wrt. option
passing to the build script and package signature checking.
This allows to utilise support for systemd-nspawn backend in build engine.
Like LXC, systemd-nspawn creates isolated lightweight container.

If no "dest" argument is specified when calling CpioRead.copyin or
CpioRead.copyin_file, a TypeError occurs in CpioRead._copyin_file
because os.getcwd(), which returns a str, is used as dest and, hence,
the subsequent os.path.join(...) fails (because it tries to join a
str and a bytes).
In order to avoid this, encode the result of os.getcwd().
Note that the existing
archive.copyin_file(hdr.filename,
os.path.dirname(tmpfile),
os.path.basename(tmpfile))
was OK because CpioRead._copyin_file os.path.join()s "dest" and
"new_fn", which are both str. It is just changed to stress that
CpioRead is a bytes-only API.
Fixes: #865 ("Traceback in osc/util/cpio.py line 128: TypeError:
Can't mix strings and bytes in path components")
Currently, when trying to initialize a non existent (server-side)
project via "osc init <prj>", osc errors out (after creating the wc)
because it fails to retrieve the package list. However, there is no
need to retrieve the package list in the "osc init <prj>" case. Hence,
skip the package list retrieval. As a result, osc does not error out.
For the background, see the discussion in #858 ("osc fails to check
out an empty project as project") [1].
