`setLang` alters the "browse" context of the documents
being printed, but it must also discard any values
already cached, as they could be using a different language.
This is the case when the report uses translatable fields
on `res.partner`, because `setLang` is usually called
with the target partner language, hence prefetching
the translatable fields with the user's language instead
of the partner's language.
E.g. `setLang(o.partner_id.lang)` will cache any
translatable field on `o.partner_id` in the language of
the *user*, not the *partner*.
While keeping the compatibility for reportlab 2.5.
Splitting the text node on line breaks '\n' leaded to orphans ending tags,
like '</font>', which is regarded by reportlab 3.0 as a paragraph,
and reportlab therefore surrounded these tags by <para> tags,
which leaded to not syntax correct html like
<para></font></para>
To test this patch:
- While having reportlab > 3.0
- Create a rml report containing (at least) '<font>\n</font>'
- Then print the report. It must not crash (obviously)
From reportlab 3.0, empty plaintext paragraphs do not lead to a break line anymore.
Before release 3.0, paragraphs having tags but no plaintext leaded to a break line.
This patch aims to recover the behavior of reportlab releases < 3.0, as
<para><font color="white"> </font></para> is used in allmost all rml reports
The current patch is not considered as clean, but we did not find any better solution.
If someone find a parameter to pass to reportlab in order to bring back the old behavior of reportlab
he is welcome to provide the better patch.
Besides, in reportlab 3.0, splitlongwords has been introduced as parameter,
to allow to break long words. The default value is True.
This parameter seems to break the columns headers
(it splits the text within the column header)
We therefore take the choice to not activate it, as it was not present anyway in reportlab < 3.0
To test the good behavior of this patch:
While having reportlab < 3.0 (2.5 for instance), print a draft invoice
Then, upgrade to reportlab > 3.0 (3.1.8 for instance), print the same draft invoice.
The generated pdf must be (allmost) identical, in particular concerning spaces.
Specifically, the space between the partner address and his phone.
Save the NumberedCanvas state before doing a page reset.
The order of execution when rendering an rml report is the following:
1. init canevas (_pageNumber = 1)
2. render the page element
3. if still pages to render, afterPage method
4. if still pages to render, showPage method (_pageNumber += 1)
5. back to step 2 for each page
6. draw the ResetPage element (setting flag _doPageReset=True)
7. end the document build with afterPage & showPage method
The PageReset element should be executed at the end of the rendering of a story (subdocument) to reinitialize the page numbers to 0 (for new story) and insert the pageCount element for that story with the total number of pages (needed if want to use tag <pageCount/> in rml).
In case of NumberedCanvas (e.g. used in Trial Balance report), the numbering is generated at the end of the build using the _saved_page_states dict in the canevas.
To have an accurate _saved_page_states content, it needs to be saved before the pageReset.
Fixes#2225
Commit b6a7402 (reverted at f8671cb) was almost correct, the PageReset should be added at the end of each stories but only if we have one more stories.
The PageReset will force the page count to be reseted at zero which means that last page of report would have been at zero.
res_font model gains family, path and mode field
Basic fonts embedded in pdf (Helvetica, Times and Courier) are data
Fix reports using font names to be valid (eg: DejaVu Sans Bold -> DejaVuSans-Bold)
default_get of res_company does not scan the filesystem anymore
family field is new name_get font for res_font (more user friendly)
Domain on displayed font to only 'normal ones' (not bold or italic)
Handle fonts in 'book' mode as normal in setTTFontMapping
Relax constraint on res_font to unique family and name ('name' was actually family before)
font_scan is called on 'reload fonts' action button and for each report rendering
font_scan is lazy when loaded from report and scanning the filesystem only if no font recorded in filesystem
'/dev/null' in font path is used to add fonts in the list but not loaded by reportlab
Scanning the filesystem triggers clear_caches
clear_cache resets the list of found fonts to empty list to make font_scan call to reload the full list (when redering a report on any worker, will always get the updated font list after a scan)
Add access rights for fonts (read everybody, create admin, call font_scan as superuser in report rendering)
Remove font hack with BaseCustomTTFonts, rely fully on the system fonts
Use glob instead of listdir (needed for path like '/usr/share/fonts/TTF/*')
Make warning message from reportlab more self-explaining.
Also make the runbot green (which is nice)
bzr revid: mat@openerp.com-20131209171338-o796pldia9da3kt2
search for TTF file on the system (in typical repositories)
add font field on the company and config wizard, the chosen value will replace the fontName value by the new one
