3 years agofix incorrect reference counting of HTML-like strings in gvpack
Matthew Fernandez [Wed, 30 Jun 2021 03:11:13 +0000 (20:11 -0700)]
fix incorrect reference counting of HTML-like strings in gvpack

When duplicating graph attributes, gvpack was calling agstrdup_html to construct
an HTML-like string and then agattr/agset to assign this to an attribute. It did
not anticipate that *both* of these increment the reference count for the string
that has been interned in the graph’s dictionary. The result was a reference
count of 2 for a new HTML-like string, despite only 1 reference to the string
existing.

This was not directly visible to users (hence no changelog entry for this
commit) and the extra reference counts are disposed of when the graph itself is
destroyed. However, this persistent off-by-one issue internally confused some
debugging and potentially retained memory longer than was necessary. The issue
was visible with the following patch applied:

3 years agogv2gxl: in GXL output, indicate when a label originated as an HTML like label
Matthew Fernandez [Thu, 24 Jun 2021 02:55:29 +0000 (19:55 -0700)]
gv2gxl: in GXL output, indicate when a label originated as an HTML like label

When translating Dot to GXL, labels come out as strings. Input something like:
`label="foo"` and the GXL output is something like
`<attr name="label"><string>foo</string></attr>`. This translation is fine and
works well, until you start using HTML like labels.

Graphviz allows `<` and `>` as delimiters to indicate your label string contains
HTML that should be parsed. When you try to use this feature in combination with
gv2gxl, you get a lossy translation. E.g. the labels `label="foo"` and
`label=<foo>` come out identically in GXL.

This commit makes use of the GXL ‘kind’ field on attributes to note that the
source was an HTML like label. If you translate the two labels from above, you
will now get:

  <attr name="label"><string>foo</string></attr>

and

  <attr name="label" kind="HTML-like string"><string>foo</string></attr>

respectively.

This is a partial fix for #517. This makes the translation to GXL no longer
lossy. The other half of this is recognizing the ‘kind’ field during gxl2gv
translation and preserving it on the way back.

This commit also drops now-unused variables, as well as the static qualifier

a small struct and both its fields are overwritten immediately when entering

BSS-allocating it.
