SYNOPSIS
use Debbugs::Status;DESCRIPTION
This module is a replacement for the parts of errorlib.pl which write and read status and summary files.It also contains generic routines for returning information about the status of a particular bug
FUNCTIONS
readbug
readbug($bug_num,$location) readbug($bug_num)
Reads a summary file from the archive given a bug number and a bug location. Valid locations are those understood by ``getbugcomponent''
read_bug
read_bug(bug => $bug_num, location => 'archive', ); read_bug(summary => 'path/to/bugnum.summary'); read_bug($bug_num);
A more complete function than readbug; it enables you to pass a full path to the summary file instead of the bug number and/or location.
Options
- bug --- the bug number
- location --- optional location which is passed to getbugcomponent
- summary --- complete path to the .summary file which will be read
- lock --- whether to obtain a lock for the bug to prevent something modifying it while the bug has been read. You must call "unfilelock();" if something not undef is returned from read_bug.
One of "bug" or "summary" must be passed. This function will return undef on failure, and will die if improper arguments are passed.
split_status_fields
my @data = split_status_fields(@data);
Splits splittable status fields (like package, tags, blocks, blockedby, etc.) into arrayrefs (use make_list on these). Keeps the passed @data intact using dclone.
In scalar context, returns only the first element of @data.
join_status_fields
my @data = join_status_fields(@data);
Handles joining the splitable status fields. (Basically, the inverse of split_status_fields.
Primarily called from makestatus, but may be useful for other functions after calling split_status_fields (or for legacy functions if we transition to split fields by default).
lockreadbug
lockreadbug($bug_num,$location)
Performs a filelock, then reads the bug; the bug is unlocked if the return is undefined, otherwise, you need to call unfilelock or unlockwritebug.
See readbug above for information on what this returns
lockreadbugmerge
my ($locks, $data) = lockreadbugmerge($bug_num,$location);
Performs a filelock, then reads the bug. If the bug is merged, locks the merge lock. Returns a list of the number of locks and the bug data.
lock_read_all_merged_bugs
my ($locks,@bug_data) = lock_read_all_merged_bugs($bug_num,$location);
Performs a filelock, then reads the bug passed. If the bug is merged, locks the merge lock, then reads and locks all of the other merged bugs. Returns a list of the number of locks and the bug data for all of the merged bugs.
Will also return undef if any of the merged bugs failed to be read, even if all of the others were read properly.
makestatus
my $content = makestatus($status,$version) my $content = makestatus($status);
Creates the content for a status file based on the $status hashref passed.
Really only useful for writebug
Currently defaults to version 2 (non-encoded rfc1522 names) but will eventually default to version 3. If you care, you should specify a version.
writebug
writebug($bug_num,$status,$location,$minversion,$disablebughook)
Writes the bug status and summary files out.
Skips writting out a status file if minversion is 2
Does not call bughook if disablebughook is true.
unlockwritebug
unlockwritebug($bug_num,$status,$location,$minversion,$disablebughook);
Writes a bug, then calls unfilelock; see writebug for what these options mean.
VERSIONS
The following functions are exported with the :versions tagaddfoundversions
addfoundversions($status,$package,$version,$isbinary);
All use of this should be phased out in favor of Debbugs::Control::fixed/found
removefoundversions
removefoundversions($data,$package,$versiontoremove)
Removes found versions from $data
If a version is fully qualified (contains /) only versions matching exactly are removed. Otherwise, all versions matching the version number are removed.
Currently $package and $isbinary are entirely ignored, but accepted for backwards compatibilty.
splitpackages
splitpackages($pkgs)
Split a package string from the status file into a list of package names.
bug_archiveable
bug_archiveable(bug => $bug_num);
Options
- bug --- bug number (required)
- status --- Status hashref returned by read_bug or get_bug_status (optional)
- version --- Debbugs::Version information (optional)
- days_until --- return days until the bug can be archived
Returns 1 if the bug can be archived Returns 0 if the bug cannot be archived
If days_until is true, returns the number of days until the bug can be archived, -1 if it cannot be archived. 0 means that the bug can be archived the next time the archiver runs.
Returns undef on failure.
get_bug_status
my $status = get_bug_status(bug => $nnn); my $status = get_bug_status($bug_num)
Options
- bug --- scalar bug number
- status --- optional hashref of bug status as returned by readbug (can be passed to avoid rereading the bug information)
- bug_index --- optional tied index of bug status infomration; currently not correctly implemented.
- version --- optional version(s) to check package status at
- dist --- optional distribution(s) to check package status at
- arch --- optional architecture(s) to check package status at
- bugusertags --- optional hashref of bugusertags
- sourceversion --- optional arrayref of source/version; overrides dist, arch, and version. [The entries in this array must be in the "source/version" format.] Eventually this can be used to for caching.
- indicatesource --- if true, indicate which source packages this bug could belong to (or does belong to in the case of bugs assigned to a source package). Defaults to true.
Note: Currently the version information is cached; this needs to be changed before using this function in long lived programs.
bug_presence
my $precence = bug_presence(bug => nnn, ... );
Returns 'found', 'absent', 'fixed' or undef based on whether the bug is found, absent, fixed, or no information is available in the distribution (dist) and/or architecture (arch) specified.
Options
- bug --- scalar bug number
- status --- optional hashref of bug status as returned by readbug (can be passed to avoid rereading the bug information)
- bug_index --- optional tied index of bug status infomration; currently not correctly implemented.
- version --- optional version to check package status at
- dist --- optional distribution to check package status at
- arch --- optional architecture to check package status at
- sourceversion --- optional arrayref of source/version; overrides dist, arch, and version. [The entries in this array must be in the "source/version" format.] Eventually this can be used to for caching.
max_buggy
max_buggy()
Options
- bug --- scalar bug number
- sourceversion --- optional arrayref of source/version; overrides dist, arch, and version. [The entries in this array must be in the "source/version" format.] Eventually this can be used to for caching.
Note: Currently the version information is cached; this needs to be changed before using this function in long lived programs.
buggy
buggy(bug => nnn, found => \@found, fixed => \@fixed, package => 'foo', version => '1.0', );
Returns the output of Debbugs::Versions::buggy for a particular package, version and found/fixed set. Automatically turns found, fixed and version into source/version strings.
Caching can be had by using the version_cache, but no attempt to check to see if the on disk information is more recent than the cache is made. [This will need to be fixed for long-lived processes.]
