  • Récupération d’informations sur le site maître à l’installation d’une instance

    Utilité
    Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
    Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

    avfilter/formats : Avoid code duplication when merging samplerates

    Right now, ff_merge_samplerates() contains three instances of the
    
MERGE_REF() macro, a macro which reallocates an array, updates some
    
pointers in a loop and frees several buffers. This commit makes it
    
possible to contain only one instance of said macro in the function,
    
thereby reducing codesize.

    avfilter/graphparser : Fix leaks when parsing inputs fails

    parse_inputs() uses a temporary linked list to parse the labeled inputs
    
of a filter ; said linked list owns its elements (and their names). On
    
success, the list of unlabeled inputs is appened to the end of the list
    
of labeled inputs and the new list is returned ; yet on failures, nothing
    
frees the already existing elements of the temporary linked list, leading
    
to a leak.
    

    This can be triggered by e.g. using '-vf [v][' in the FFmpeg
    
command-line tool.
    

    This leak seems to exist since 4e781c25b7b1955d1a9a0b0771c3ce1acb0957bd.

  • avfilter/af_amix : Fix double-free of AVFilterChannelLayouts on error

    7 août 2020, par Andreas Rheinhardt
    avfilter/af_amix : Fix double-free of AVFilterChannelLayouts on error

    The query_formats function of the amix filter tries to allocate a list
    
of channel layouts which are attached to more permanent objects
    
(an AVFilter's links) for storage afterwards on success. If attaching
    
a list to a link succeeds, the link becomes one of the common owners
    
of the list. Yet if a list has been successfully attached to links (or if
    
there were no links to attach it to in which case
    
ff_set_common_channel_layouts() already frees the list) and an error
    
happens lateron, the list was manually freed, which is wrong, because
    
the list has either already been freed or it is owned by its links in
    
which case these links' pointers to their list will become dangling and
    
there will be double-frees/uses-after-free when these links are cleaned
    
up automatically.
    

    This commit fixes this by removing the custom freeing code ; this is made
    
possible by using the list in ff_set_common_channel_layouts() directly
    
after its allocation (without anything that can fail in between).
    

    Notice that ff_set_common_channel_layouts() is buggy itself which can
    
lead to double-frees on error. This is not fixed in this commit.
