14404. By Alex Rousskov on 2016-03-11

Polished to address official review concerns.

No functionality changes expected.

14403. By Alex Rousskov on 2016-03-10

Code polishing, including ShmWriter move, and trunk diff reduction.

No functionality changes expected.

14402. By Alex Rousskov on 2016-03-10

Removed stale shm segment initialization fix.

We have already merged a better version of this fix from trunk, and
the stale parts were not doing anything useful since then.

14401. By Alex Rousskov on 2016-03-09

Explicitly #include <functional> when using std::function.

This solves compilation problems in some environments.

14400. By Alex Rousskov on 2016-03-02

Fixed header update for entries cached on disk but not in shared memory.

mem_obj->memCache.index is not set for shared memory-cached entries that
have been already copied into local RAM. It is just a "hint". Using it
as an authoritative reference leads to exceptions and stuck
transactions.

SourceFormat Enforcement

14398. By Alex Rousskov on 2016-02-29

Merged from trunk (r14571) to get recent CVE/stability fixes.

14397. By Alex Rousskov on 2016-02-29

Removed Ipc::IdQueue until we start push()ing .waitingToBeFreed names.

14396. By Alex Rousskov on 2016-02-29

Fixed handling of zero fileno. The FileNos map cannot both use zero to
mark stationary files and store a moved file location of a fileno==0
file. Store (fileno+1) instead and provide relocate() API.

Also removed victim iteration code duplication, closing a TODO.

Also removed .waitingToBeFreed=false code duplication. We always
rewind() when we clear that flag.

Also added an Ipc::Mem::PageStack-based Ipc::IdQueue to store names of
.waitingToBeFreed files. Squid does not yet push into the corresponding
"scrap" queue yet, and we will probably need a flag to mark anchors
listed as scrap (avoiding duplicate listings).

Increment loading entry size _before_ freeBadEntry() validates it.
