The ':' character is used as a separator in Open Build Service
and constantly appears in directory names after running osc commands.
Windows do not support ':' as a valid character on file system.
This breaks not only osc but also basic commands such
as 'git clone' on a project that contains colons in paths.
That's why we decided to make osc unsupported on Windows.
Do not fail with a traceback if the config file parsing fails.
Hence, catch the configparser.Error exception and print its
"message" attribute to the user.
Fixes: #985 ("Type error on any osc call")
Since a recent backend change, a bdep has a hdrmd5 by default. That
is, osc always downloads these bdeps from the API (unless they are
cached) instead of a mirror. This is not intended.
Using a mirror is no problem because the hdrmd5s are verified in
the build module.
Note: If this causes a problem, one could also use "osc build
--download-api-only" to mimic the old behavior.
If the oscrc is a symlink, follow the symlink when writing the
configuration file. The old code replaced the symlink with a
regular file (see #390 ("symlinked $HOME/.oscrc gets replaced
with a ordinary file")).
Implementation note: if the directory, which contains the resolved
config file, has a <config file>.new file, the file is overwritten.
When a user creates a symlink pointing from ~/.config/osc/oscrc
to a different location, don't overwrite the symlink but follow
it when writing configuration on disk.
Without escaping the % character, the download URL could be subject
to string formatting (depending on the subsequent characters). For
instance, if the url attribute's value of a buildinfo's path element
contains the substring "c_c%2B%2B", the "%2B" is interpreted as a
format string (see issue #965), which is wrong ("B" is not a valid
format character at all). In order to avoid this, escape all
% characters in the download urls.
Note: escaping the % characters in the download url itself is OK
because we only intend to "format" the path.
Note: we do not escape the % characters for urls from the config
file (implicit assumption: the user already correctly escaped the
urls (whether this assumption is sensible or not is debatable, of
course)).
Fixes: #965 ("unsupported format character 'B' (0x42) at index 66")
The old code passes try_again=False to the recursive postoptparse
call when calling it from one of the exception handlers. This is
wrong because it can result in an incomplete conf.config dict (for
instance, if two apiurl sections have no user and no password and
no credentials_mgr_class option - see #761 ("Traceback config with
two backends and no username")).
Hence, Osc.postoptparse should only return if the conf.get_config
call succeeds. For this, unconditionally call Osc.postoptparse from
within the exception handlers. Note: this could potentially (although
quite unlikely) result in an endless recursion but in each recursive
call "user" interaction is required (that is, the user could simply
press CTRL+c) - so this should not be a problem.
Implementation note: this change breaks the API. Rationale: the
semantics of Osc.postoptparse changed. Hence, "pretending" to
honor the try_again parameter could result in unexpected behavior
(from the API consumer's POV). Hence, a traceback might be more
sensible.
Fixes: #761 ("Traceback config with two backends and no username")
Support a zst compressed control.tar in debquery.DebQuery. A zst compressed

Do not create an MR for the entire project if "osc mr" is invoked in
a package wc (only create an MR for the specific package instead).
Strictly speaking, the "breaks" the existing UI - but this rather seems
to be a "fix" than a "break";)
Some of our repositories have specific download urls. osc is ignoring
this so far and just tries to use the generic downloadurl
This code prefers definitions for individual path elements if they exist.
We could IMHO remove the old code, since old OBS instances would still
work via the api download fallback.
Real life examples for repo specific configs are on openSUSE all
repositories outside of the /repositories/ directory. eg.
<path project="openSUSE:Tumbleweed" repository="dod" url="http://download.opensuse.org/tumbleweed/repo/oss/"/>

The old code does not print any information about the host, for
which the access failed, in case of an URLError. In order to fix
this, add information about the host (and port) to the URLError
instance in core.http_request and use this information in the
babysitter to print out a more detailed error message (which includes
the host (and port)).
For now, we simply add a "private" "_osc_host_port" attribute to
the URLError instance (this way we avoid potential name clashes (due
to the "_osc" prefix) and could come up with a different/more clever
way in the future (due to its privateness)).
Fixes: #954 ("Better diagnostic for domain name issues")
os.sysconf is not available on all platforms (like Windows) but it
is used to retrieve the number of online processors. If missing,
assume one processor (building on such a platform will most likely
not work, though).
Fixes: #948 ("Windows compatibility") (at least it improves the
Windows support a bit)
A workflow token can be created via "osc token --create --operation
workflow --scm-token <SCM_TOKEN>".
Triggering a workflow token via osc is probably unlikely - that's
why it is not yet implemented (it would also make the UI a bit
awkward because one has to specify a concrete http header).
Fixes: #943 ("implement osc token --operation=workflow")
The use of makeurl makes the code more readable/maintainable (IMHO)
and it also does proper percentage encoding of the query string (not
that the osc codebase cares much about it, though:/).

Offer a force ("f") choice if, for instance, "osc meta prj foobar -e"
fails due to a HTTPError in metafile.edit. If the force choice is
selected, a new url is constructed by invoking the metafile._URLFactory
instance with a "force='1'" argument (this adds a "force=1" to the
original url's query string (*)) and the corresponding file is PUTed
to the new url. If this PUT fails again and now the "y" choice is
selected, the file is PUTed to the original url (*).
(*): Stricly speaking, from metafile.edit's POV, the concrete url
depends on the passed in metafile._URLFactory instance, though.
Note: the metafile._URLFactory class and its is_force_supported method
is a gross hack. That's why this class is marked as private (that is,
we can remove it at any point in time again without breaking the
API/3rd party applications). An alternative to the metafile._URLFactory
approach would be manual URL parsing and manual URL construction
(adding "force=1" to the query string)... but this is also pretty
awkward (if done properly).

Do not try to run source services when building in a non package wc. This
is the behavior we had prior commit c39c3b8cae
("Cleanup the source services execution code in do_build").
There is no "sane" way to execute the source services in case of a
non package wc build because we cannot export the OBS_SERVICE_PACKAGE
env variable with a meaningful value.
Fixes: #936 ("'osc build --local-package ...' fails with 'not an osc
package working copy'")
When building a package from a directory that is not a checked-out
OBS working, the error message:
"Error: "<directory>" is not an osc package working copy."
is generated.
This occurs when build.main() attempts to run source services which
is probably not a good idea as these are part of the core.Package
infrastructure which cannot be initialized for such packages.
It is probably best to disable the source services in this case.

The old code does not support the --binary option in combination
with the --verbose option. Specifying --binary and --verbose at
the same time results in a crash (because the binary listing
contains no <title>...</title> element).
In order to fix this, do not try to access a <title>...</title>
element when --binary and --verbose are both specified. Instead,
in this case, include information about the repo, arch, version,
and release of the corresponding binary element.
Fixes: #933 ("osc se -v -B crash")
The old code uses a variable .rXYZ suffix (where XYZ is the revision
of the package wc during the merge operation). Now, if Package.mergefile
is invoked during an update, XYZ represents the "old" revision. That
is, if a merge conflict happens, then a subsequent "osc resolved <file>"
will not unlink the <file>.rXYZ file (because
Package.clear_from_conflictlist only takes the current rev into account).
In order to fix this, use a fixed ".new" suffix. This way,
Package.clear_from_conflictlist can properly unlink the corresponding
*.new file. This naming scheme for the "upfilename" is in line with
"osc pull" and "osc repairlink".
Note: if a working copy was updated with an "old" osc version (without
this commit) and a "new" osc version (with this commit) is used to run
"osc resolved <file>", then the <file>.rXYZ file is _NOT_ removed (it
is not worth the effort to add compat code for this).
A password can be deleted via "osc config -d <apiurl> pass". Actually,
if we really want to support password deletion, we should introduce
a --delete-password option because the "pass" config option can be
considered as an implementation detail, which we should not expose
to our users.
The password store can be changed (without entering the password
again) via "osc config <apiurl> --select-password-store". This
command deletes the password from the current password store and
stores it in the selected password store.
Previously, the --select-password-store option had no meaningful
semantics. In order to use it, one always had to provide a password
and explicitly pass "pass" as the config option (the same could be
achieved by using --change-password). Hence, in a strict sense,
this change breaks the UI.
Without the slash splitting, "osc browse prj/pkg" interprets the
argument as a project, which is wrong. Hence, perform the slash
splitting (as most commands do).
Always send the sha256sums of all tracked files in case of a
frozen package wc. For instance, this is needed if the package is
a plain link (no branch) because in this case the backend might
request a sha256sum for a tracked but unmodified file (this can
happen because the backend cannot expand the link).
The new behavior is in line with a pulled/linkrepair package wc.
Fixes: #924 ("Transmitting file data There is no sha256 sum for
file")
When trying to commit a non-existent package via Project.commit it
is treated as an external package (because a non-existent package
has no "state" inside the project). That is, Project.commitExtPackage
is called, which fails with a FileNotFoundError in case of a
non-existent package (and the traceback is printed to the user).
In order to fix this, treat a non-existent package as broken package.
That is, simply print an info message and do not error out with a
traceback (note: the commit is _not_ aborted).
Fixes: #920 ("osc commit should fail gracefully in case of
nonexistent filename")
Sccache is an alternate build caching system to ccache/icecream. It
supports C, C++ and Rust. It can optionally have distributed or remote
caches via redis, s3 object stores, memcached, azure storage or
google cloud storage.
This can help to significantly improve the performance of Rust rebuilds.
For example, Kanidm changes from 400s to 122s on a rebuild, and rust-lang
rebuilds improve from 7200s to 4770s. With some changes to the rust
packages especially this will be possible to speed up over version
changes as well.

Do not use a preinstallimage if the local build is executed as a non-root

by a non-root user - this is not a problem in the non-preinstallimage
codepath (see [1])).

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.

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".

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.
Fixes: #869 ("Silly encoding of htmlencodable entities")
So far, core.get_prj_results only supports a substring based name
filtering mechanism. Now, a regex based name filtering mechanism
is used. That is, if the regex matches a package name, the package
is not filtered out.
This is an API incompatible change:
- 3rd party code which looks like this is going to break:
class Foo(str):
...
def __eq__(self, other):
return ...
... = core.get_prj_results(..., name_filter=Foo())
(My gut feeling says there are no such callers. However, if this
really breaks any serious code, we can fix it in a follow-up commit)
- "osc prjresults openSUSE:Leap:15.2:Update --name-filter zypper." will
now also show "zypper-docker" etc. because the dot (".") matches any
character (except a newline). Previously, only packages that contained
the str "zypper" followed by a dot (".") were shown. The old behavior
can be restored, if the dot is escaped: "osc prjresults
openSUSE:Leap:15.2:Update --name-filter 'zypper\.'".
Of course, this affects all other special characters, too.
Additionally, if an illegal regex is passed to the --name-filter option,
an exception is raised. The previous code did not fail.
This can break existing workflows and scripts. We could avoid this by
introducing a --name-filter-regex option but this would clutter the
UI (IMHO).
A regex based name filtering feature was requested by darix.

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))

"new_fn", which are both str. It is just changed to stress that
CpioRead is a bytes-only API.

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.
