* imgdiff: skip spurious gzip headers in image filesDavid Riley2015-12-281-6/+14
| | | | | | | | | | | | | dragon kernel is compressed via lz4 for boot speed and bootloader support reasons and recent prebuilts happen to include the gzip header sequence which is causing imgdiff to fail. Detect a spurious gzip header and treat the section as a normal section.

| | | | | | | | | | mkstemp() allocates a file description that is never released. If MakePatch() is called too many time, imgdiff reaches the Operating System EMFILE (too many open files) limit.

* Use f_bavail to calculate free spacecaozhiyuan2015-06-261-1/+1
| | | | | | | | | | | | | Failures are seen on devices with Linux 3.10. And they are mainly due to this change: https://lwn.net/Articles/546473/ The blocks reserved in this change is not the same thing as what we think are reserved for common usage of root user. And this part is included in free blocks but not in available blocks.

* | fix unnecessarily slow writing of EMMC partitionsDoug Zongker2013-12-191-15/+3
|/ | | | | | | | | | | These were attempts to write partitions "conservatively" in hopes of fixing the problems with writing the radio partition on Nexus 4. They didn't work (a kernel patch was needed), but got left in. They make writing of partitions unnecessarily slow (ie, we really shouldn't need to sync() after every 4kb). Roll back most of them, but leave the verification read-back in. Change-Id: I94badc0979e88816c5aa0485f6316c02be69173c

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nexus 4 has flash errors that manifest during large writes (eg, of the radio partition). Writes of some blocks seem to be dropped silently, without any errors being returned to the user level. Make two changes to the partition-writing code: - break it up into 1MB writes instead of writing partitions with a single fwrite() call. Pause for 50ms in between every chunk. - read the partition back after writing and verify that we read what we wrote. Drop caches before reading so we (hopefully) are reading off the actual flash and not some cache. Neither of these should be necessary.

| | | | | | | | | | | Make minzip log only a count of files when extracting, not individual filenames. Make patching only chatter about free space if there's not enough and compact the other messages. Only the last 8k of the recovery log gets uploaded; this makes it more likely that we will get all of it. Change-Id: I529cb4947fe2185df82b9da5fae450a7480dcecd
* add bonus data feature to imgdiff/imgpatch/applypatchDoug Zongker2012-08-205-21/+99
| | | | | | | | | | | | | | The bonus data option lets you give an additional blob of uncompressed data to be used when constructing a patch for chunk #1 of an image. The same blob must be available at patch time, and can be passed to the command-line applypatch tool (this feature is not accessible from edify scripts). This will be used to reduce the size of recovery-from-boot patches by storing parts of the recovery ramdisk (the UI images) on the system partition.

Remove it. Enforce an absolute minimum of free space as well, to avoid running into problems patching small files, now that the copy-to-cache path is (inadvertently) well-tested.
