In `@backend/copr_backend/background_worker_build.py`:
- Around line 597-598: Update the archive creation flow around tarfile.open and
tar.add so uploaded_logs_dir is removed only after the archive is created
successfully; do not delete it in the finally block when an OSError occurs,
while preserving the existing error logging and cleanup behavior for successful
creation.
- Around line 592-594: Update the uploaded-log archive flow around tarfile.open
so an existing tarball_path is detected before opening; log the collision and
return immediately, preserving uploaded-logs for retry. Only create the archive
when the path does not already exist, while retaining the existing cleanup
behavior for successful new archives.
In `@cli/copr_cli/main.py`:
- Around line 1772-1775: Make the uploadrpm --logs contract unambiguous with
positional rpms by changing the option to accept one log path per occurrence
while retaining support for multiple logs. Update the --logs definition near
uploadrpm in cli/copr_cli/main.py and adjust the documented command in
cli/man/copr-cli.cheat (lines 39-42) and the Beaker command in
beaker-tests/Sanity/copr-cli-basic-operations/runtest-rpm-upload.sh (lines
154-158) to use the selected repeatable single-value form; ensure
action_upload_rpm receives all RPM paths and still invokes
create_from_rpm_upload.
In `@frontend/coprs_frontend/coprs/logic/builds_logic.py`:
- Around line 742-743: Update the suffix validation condition in the surrounding
build-upload method to compare the sanitized filename using the same lowercase
normalization as the form validators, while preserving the existing
allowed_suffixes and reject_suffixes checks and BadRequest behavior.
- Around line 762-765: After sanitizing filenames in the RPM processing flow,
validate that both sanitized RPM names and sanitized log names are unique before
any files are saved. Reject the upload when a collision is detected, rather than
allowing later entries to overwrite earlier files or leaving source_json
inconsistent. Use the existing _sanitize_uploaded_filename logic and the
collections built alongside rpm_names.
In `@frontend/coprs_frontend/coprs/views/backend_ns/backend_general.py`:
- Around line 216-219: Preserve compatibility with existing rpm_upload metadata
by updating the backend_general.py build-record construction at lines 216-219 to
use source_data["files"] when the rpms key is absent, while retaining rpms for
newer records. Also update _describe_source.html lines 82-86 to render files
when rpms is absent so existing uploaded RPMs remain visible.

Refresh the Copr repository metadata before this install.
The first phase caches metadata for the enabled repository. The later phase builds $PACKAGE_MULTI, waits only for the build state, and installs from the same repository without refreshing metadata. A valid cache may omit the new packages and cause the install to fail. Add --refresh.

WTForms IntegerField NumberRange accepts negative integers documentation
💡 Result:
Yes, WTForms IntegerField and the NumberRange validator fully support negative integers [1][2]. The NumberRange validator is designed to work with any comparable number type, including negative integers, by checking if the field's data falls within the specified min and/or max range [1][2]. If you are encountering issues where negative numbers are not being validated correctly, it is typically due to one of the following reasons: 1. Form Validation Method: Ensure you are calling form.validate_on_submit (in Flask-WTF) or form.validate rather than checking if the form was just submitted [3]. 2. Data Coercion: IntegerField coerces form data to an integer [4]. If you are passing data directly to the field (e.g., in a dictionary) during form construction without using the proper formdata argument, the data may remain a string and fail validation because it cannot be compared against integer bounds [5]. 3. Validator Configuration: Ensure the min and max parameters in NumberRange are set correctly to include the desired negative range (e.g., NumberRange(min=-100, max=0)) [1][6]. The NumberRange validator performs an inclusive check using standard Python comparison operators (e.g., data >= self.min and data <= self.max) [1][2], which natively support negative values.

RPM packaging Epoch field non-negative integer EVR syntax official documentation
💡 Result:
In the RPM packaging system, the Epoch is a non-negative integer used to override the default version-release sorting order [1][2]. It serves as the most significant component in the EVR (Epoch:Version-Release) syntax [1][2]. Key details regarding the Epoch field include: Syntax: The full EVR syntax is represented as [EPOCH:]VERSION[-RELEASE] [1][2][3]. The Epoch is separated from the Version by a colon (:) [1][4]. Behavior and Requirements: 1. Non-negative Integer: The Epoch must be a non-negative integer [1][2]. 2. Default Value: If the Epoch is not specified in an RPM package, it has an implicit value of zero during comparisons [1][2][5]. 3. Precedence: Because it is the most significant part of the EVR string, a package with a higher Epoch will always be considered newer than a package with a lower Epoch, regardless of the Version or Release components [1][2][5]. 4. Best Practices: Its use is generally discouraged and considered a last resort for resolving versioning anomalies (e.g., when an upstream project changes its versioning scheme) because it violates the principle of least surprise and requires manual updates to any related versioned dependencies [1][2][5]. Dependencies: When defining dependencies that include an Epoch, the full syntax [epoch:]version[-release] must be used [4][6]. For example, a dependency would be written as Requires: somepackage = 23:1.2.3-4 [4][6].

Mark the required upload fields in the API schema.
When direct RPM upload is enabled, CreateFromRpmUpload advertises tarball, name, version, and release as optional because CreateBuildRpmUpload.required_attrs is empty. BuildFormRpmUploadFactory requires all four fields and returns BadRequest when validation fails. Override required_attrs so the generated API model matches the reachable form contract.

Preserve legacy direct-RPM serialization for existing builds
When source_json contains tmp and files but no tarball, this code emits a prebuilt_tarball_url ending in /None. rpmbuild/main.py then selects the tarball path instead of the legacy prebuilt_rpm_urls path, so the pending build cannot process its uploaded RPMs. Emit prebuilt_rpm_urls when files is present, and emit prebuilt_tarball_url only for new tarball-based builds.

Close the tarball handle in a finally block.
FileRequest passes the handle to MultipartEncoder, which does not close caller-owned files. _create() sends the request synchronously, but it has no cleanup path when the request succeeds or raises. Repeated uploads can keep descriptors open until garbage collection. Close the handle after _create() returns or raises.

Python TarFile.extract filter parameter introduced Python 3.12 security backport 3.8.17 3.9.17 3.10.12 3.11.4 official documentation
💡 Result:
The filter parameter for the tarfile.extract and tarfile.extractall methods was introduced in Python 3.12 [1][2] and backported to security releases of older Python versions, specifically versions 3.11.4, 3.10.12, 3.9.17, and 3.8.17 [3]. This feature was implemented to address security vulnerabilities associated with extracting untrusted archives (such as path traversal attacks) [4][3][1]. The parameter allows users to specify how archive members are processed or restricted before they are written to the filesystem [1][5]. Key details regarding the implementation and use: 1. Recommended Practice: Because the filter parameter is not present in versions older than these security releases, official documentation recommends checking for its availability using hasattr(tarfile, 'data_filter') rather than relying on Python version checks [1][2]. 2. Usage: When the filter is available, users are encouraged to explicitly set it (e.g., filter='data') to prevent dangerous behaviors [1]. If the filter argument is not provided (and no global extraction_filter is set), the behavior defaults to 'fully_trusted' in older versions for backward compatibility [1][5]. 3. Security Backport Exception: Although CPython typically avoids adding new APIs in security patch releases, an exception was made for this feature because it was deemed essential for security, and the new API (including the filter argument and TarFile.extraction_filter) was required to make the feature functional [4]. 4. Evolution: While initially backported with a 'fully_trusted' default (to maintain compatibility), the system is designed to allow safer defaults. In Python 3.14+, the 'data' filter became the default [2][6].

Preserve Python compatibility for EL7
The package spec advertises epel-7, and EL7 Python 3 does not provide the TarFile.extract(..., filter=...) parameter. This call therefore raises TypeError during extraction. Either keep EL7 support with a backport-compatible safe extraction path, or declare a minimum Python version that provides filter="data".

💡 Result:
In the context of RPM packaging, architecture tags identify the specific processor family and instruction set that a package is built for. These tags ensure that package managers like DNF install software compatible with the user's hardware. x86 Architectures (Intel/AMD) These represent variations of the 32-bit x86 instruction set, with each level requiring support for more modern CPU features: - i386: The baseline architecture for the 32-bit Intel x86 instruction set, historically compatible with the Intel 80386 processor and later. - i586: Targets processors starting with the Intel Pentium (P5). - i686: Targets processors starting with the Intel Pentium Pro, Pentium II, and later, supporting additional instructions not present in older 32-bit chips. ARM Architectures These tags refer to specific configurations of the 32-bit ARM architecture, which differ primarily in their handling of floating-point arithmetic and instruction set versions: - armv7hl: Refers to ARMv7-A architecture with hardware floating-point support (hard float) and little-endian byte order. The 'h' indicates hard-float, and 'l' indicates little-endian. This is a common standard for many modern 32-bit ARM systems. - armhfp: Often used interchangeably or as a broader categorization for ARM architectures utilizing hardware floating-point (Hard Float) units, distinguishing them from soft-float configurations which perform floating-point calculations in software. Package managers use these identifiers to filter repository metadata, ensuring that if a system is running on a 686-compatible or ARMv7-capable processor, it only retrieves and attempts to execute binary code designed for its specific capabilities.

validate_binary_rpm_archs accepts only an exact match between hdr["arch"] and the final chroot component, plus noarch. This can reject valid i686/i586 RPMs for i386 chroots and armv7hl RPMs for armhfp chroots. Compare each header against a compatibility set for the chroot architecture.

Convert malformed sha256.json into a RuntimeError.
process_uploaded_tarball loads sha256.json before calling verify_sha256_manifest. Invalid JSON raises json.JSONDecodeError. Valid JSON that is not an object causes AttributeError when verify_sha256_manifest calls .items(). main_daemon handles RuntimeError as a build error, but re-raises these exception types and produces an unhandled traceback. Validate the parsed type and wrap the decode error.

@nikromen, I checked the builder path.
main.py catches RuntimeError, but it does not catch json.JSONDecodeError or AttributeError. Invalid JSON raises json.JSONDecodeError. A JSON array or string raises AttributeError at manifest.items().
These cases fail the process, but they bypass the normal Copr build error handling and produce an unhandled traceback. The conversion to RuntimeError is required for consistent build-error reporting.
